To all whom it may concern:

Be it known that I, LOUIS C. RODIER, of Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Planes; and I do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to bench-planes, and more particularly to metallic bench-planes, and has for its object, first, the combination, with a stock, of an improved knife holder or carriage provided with devices for operating the same and adjusting the knife to secure the desired depth of cut; second, the combination, with a stock, of a novel attachment for holding a toothing iron or scraper; third, to combine in a bench-plane the said knife-holder and said attachment for toothing irons and scrapers, said attachment being removable, so that the knife or bit may be removed and the toothing or scraper attachment be engaged with the stock,or said attachment be removed and the knife inserted, the plane being thus readily convertible for various uses; and, fourth, it consists in the general construction and arrangement of the novel devices, hereinafter described, and more particularly pointed out in the claims.

I carry out my invention as follows:

In the drawings, Figure 1 is a longitudinal section of a jack-plane, showing the knife-holder in position with the knife or bit in place. Fig. 2 is a similar section showing the toothing or scraper attachment in position. Fig. 3 is a modihcation adapting features of the device more particularly for a smoothing-plane or block-plane. Fig. 4. is a separate view of the toothing iron and scraper attachment. Fig. 5 is a cross-section along the line at x y, Fig. 6. Fig. 6 is a view showing the knife-carriage and its operating devices. Fig. 7 is a side elevation.

A represents the stock provided with a throat, a.

B is the knife-rest, which may be constructed of any suitable form or pattern, and adapted to hold the knife on a proper incline. It may be provided with ears b extending upward at the side of the knife, or these ears may be dispensed with, as shown in Fig. 3. This knife-rest is provided with a rearwardly-extending arm, b’, provided with a screw-orifice, b2, (shown in Fig. 1,) or otherwise adapted to receive the head of a screw, and to receive its force, as shown in Fig. 3. I also prefer to construct the knife-rest, when applied to jack-planes, with an extended knife-brace, b8. This knife-rest may be secured within the walls of the stock and suitably adjacent to the throat in any suitable manner, as sh own in Fig. 5. The knife-rest is screw-tapped to receive the screws b3 and b4 These screws are preferably constructed with rounded ends to engage in corresponding sockets, a’ and a2, in the base of the stock, the construction being such that the knife-rest may have a movable or slightly-vibratory movement, so that either side of said knife-rest may be elevated or depressed to more effectually adjust the knife to cut evenly across its entire edge.

C is a spring engaged with the knife-rest at one end, as shown at c, and under the arm b’
and upon a raised bed, A’, upon the base of the stock.

D is a bridging constructed preferably integral with the stock, under which the spring is extended, said bridging also preferably provided with a screw, d, adapted to bear upon the spring to give it greater tension upon the knife-rest. I do not limit myself to any special construction of this bridging.

The bed A’ is screw-tapped, as shown at a3, to receive a screw, B’.

B2 is a thumb-nut adapted to operate upon said screw, and to bear upon the rear of the arm b’ to tilt the knife-rest to any desired angle.

E is a knife-clamp provided with hooked arms e, adapted to engage over the ears b of the knife-rest, said ears being suitably cut away at their rear edge to receive said hooked arms, so that the one will be flush with the other, as shown in Fig. 7. The side walls of the stock are preferably cut away slightly to receive said ears and arms also, as shown also in Fig. 7.

E’ is a thumb-screw tapped into said clamp and adapted to tighten and hold the knife upon the knife-rest beneath. F is the knife. The clamp may have, however, any suitable engagement with the knife-rest.

When the thumb-nut B2 is forced down upon the arms b’ of the knife-rest, the effect will be to tilt the knife-rest and so adjust the knife relatively to the throat, said rest being adapted to have a slight longitudinal vibratory motion upon the ends of the screws b3 and b4, as well as a vibratory motion across the stock, while the pressure of the thumb-screw E clamps the lower part of the knife-clamp upon the knife near its cutting-edge, so that the knife is held firmly between said clamp and the knife-rest. The knife is thus readily held in position. The knife may be put in place by loosening the clamp, which is then raised to disengage its hooked arms from the ears of the knife-rest. When the knife is in place, the clamp is forced down so that its hooked arms shall be engaged over the ears of the knife-rest, and the thumb-screw may be tightened thereon when the cutting-edge of the knife has been properly adjusted.

As shown in Fig. 3, instead of providing the knife-rest with the screws b3 and b4, having rounded ends, forming the bearings of said rest, I may construct said rest with integral bearings or lugs b5, answering the same purpose as the screws in Fig. 5, the only difference being that the knife-rest cannot readily be adjusted across the stock as can be done, as already described, where the screws b3 and b4 are employed. So, also, instead of engaging the spring in the knife-rest, as shown in Figs. 1 and 2, the tension may be secured in essentially the same way by constructing the arm b with a cross-bar, as shown at b6, in which case the end of the spring may be engaged under the bridging, being passed over said cross-bar, as shown in Fig. 3, the tension being secured by means of the screw B’. By operating said screw the knife-rest may be tilted, as before, to secure the desired adjustment of the knife relative to the throat to make it cut more or less, as may desired.

To insure the proper location of the knife upon the rest and relatively to the throat, I also prefer to construct the knife with an orifice, f adapted to engage over a lug, G, which may be adjustably located beneath it either upon the spring, as shown in Fig. 3, or upon an arm, b7, integral with the knife-rest. This device when the lug is once adjusted properly will permit the ready engagement of the knife relatively to the throat, and when the knife becomes worn the lug can be adjusted to compensate for the wear.

H represents my improved toothing iron or scraper attachment, substantially as shown in Fig. 2, consisting of a suitable front clamp, H’, and rear clamp, H2, the front clamp being preferably provided with engaging-arms h, adapted to engage upon the rear clamp, said clamps provided with thumb-screws h and h2 to bind the toothing iron or scraper H3 between said clamps, as shown in Fig. 2. By means of the said screws the toothing-iron may be readily engaged in said clamps or removed thereupon for the insertion of the scraper, as desired, said clamps forming a holder or harness for the cutting-tool.

The rear clamp is provided with a wing, h3, constructed and arranged to be seated upon the knife-rest B. The knife-clamp E is then clamped upon the wing, the knife F being removed, which holds the said attachment firmly in place. It is evident that this attachment may be readily removed and the knife inserted, and vice versa.

Instead of engaging the wing h3 upon the knife-rest by means of the knife-clamp already described, the wing itself may be provided with engaging-shoulders h4, similar to the hooked arms e of said clamp, and serving a similar purpose.

I design to provide the stock of the plane with a scale-bar or measure, as shown in Fig. 7. The spring serves to take up any slack which may result in the adjustment of the knife-rest by means of the screw B’.

In the jack-plane, as shown in Figs. 1 and 2, the spring is engaged with the knife-rest forward of the bearings b3 and b4. In Fig. 3 the spring is engaged with the rest in the rear of the bearings, the spring operating simply in a reverse manner to take up the slack.

Instead of a screw, B’, a suitable cam may be employed. I would have it understood that I do not limit myself to the screw alone to secure this proper adjustment.

I do not limit myself to the definite and precise construction of the parts H’ and H2 of the attachment, as shown, nor providing the part H2 with a wing, h3, as they may be of any suitable construction to removably hold the toothing iron or scraper suitably in position in the stock.

What I claim is —

1. The combination of a plane-stock, a knife-rest provided near its lower end with a support which permits the rest to be tilted in the direction of the length of the stock and also transversely thereto, a spring to exert an upward pressure upon the rest, and means to regulate the longitudinal tilting of the rest, substantially as described.

2. The combination of a plane-stock, a knife-rest, screws passed through said rest near opposite sides thereof and bearing against said stock to permit the rest to be tilted in the direction of the length of the stock and transversely thereto, a spring to exert an upward pressure upon the rest, and means to regulate the longitudinal tilting of the rest, substantially as described.

3. The combination of a plane-stock, a knife-rest, screws passed through said rest near the opposite sides thereof and bearing against said stock to permit the rest to be tilted in the direction of the length of the stock and transversely thereto, a spring to exert an upward pressure upon the rest, means to regulate the tension of said spring, and a screw to regulate the longitudinal tilting of the rest, substantially as described.

4. The combination of the plane-stock, the knife-rest, a support under the rest, a lug, G, supported by and capable of sliding longitudinally on the support and adapted to engage and move with a knife, a knife-clamp above the rest, and a screw engaging a screw-socket in the clamp for holding the knife upon the rest, substantially as described.

5. The combination, with a metallic plane-stock, of a removable toothing iron or scraper composed of two clamps provided each with a clamping-screw, one of said clamps being provided with a wing to engage with a knife-rest on the stock, substantially as described.

6. The combination, with a plane-stock provided with a knife-rest and knife-clamp, of a removable toothing iron or scraper attachment consisting of front and rear clamps constructed and arranged to be engaged with each other and provided with clamping-screws, said rear clamp provided with a wing, h3, adapted to be engaged upon the knife-rest, the construction being such that said attachment may be removed and the knife be clamped upon the rest, and vice versa, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

To all whom it may concern:

Be it known that I, HENRY P. COPE, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Router-Planes, of which the following is a specification.

Figure 1 is a perspective, the iron and clamp being removed. Figs. 2 and 3 are vertical sections on the center of the iron, and Fig. 4 is a horizontal section through the thumb-screw which holds the iron in place.

My invention consists in an improvement in router-planes, whereby the iron can be set either within or without the stock, to adapt the plane for working into corners.

A represents the stock, having an opening therein, as is usual in router-planes. I usually make the stock of cast metal, thickened around the edges and opening, as shown in Fig. 1; but this is not material, as the stock may be made of any suitable shape and material.

B B represent handles secured to the stock.

C represents a post cast with or secured to the stock between one edge thereof and the opening therein. The opposite sides of post C are flattened, and a groove, D, cut therein on each of the two flattened sides.

E represents the plane-iron, which is shown as having a square shank, the sides thereof being the same or nearly the same width as the flattened sides of post C, and having a cutting end projecting at an angle from the lower end of the shank.

F represents a metal clamp having one portion adapted to fit post C, and another portion adapted to fit the shank of the iron, as clearly shown in Fig. 4.

G represents a set-screw working in a screw-thread tapped through clamp F, its end being adapted to engage with one of the grooves D, as clearly shown in Figs. 2, 3.

The operation of my invention is as follows: The iron being set as shown in Fig. 2, so that the cutting-edge projects through the opening in the stock, clamp F is slipped over the square shank of the iron and post C, until set-screw G is opposite one of the grooves D, when, by turning up set-screw G, the iron E is firmly clamped to post C, and the plane is ready for all work which can be done by an ordinary router-plane. By loosening the set-screw the iron can be raised or lowered to suit the work to be done. When it is necessary to rout out a channel close to a projecting piece which cannot be reached by the ordinary router-plane, because the stock comes in contact with the projecting piece before the iron reaches the end of the channel, I shift the iron E to the outer side of post C and reverse clamp F, as shown in Fig. 3, so that the iron works entirely outside of the stock and will work close up to a projection.

It is evident that many alterations may be made in the shape of the post, the shape of the iron, and the manner of securing the iron to the post, so that its cutting-edge may be placed at will inside or outside of the stock, without departing from the principle of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is —

1. A router-plane having a support secured to its stock between one edge thereof and an opening therethrough, combined with means for connecting the plane-iron to either the inner or the outer portion of said support, to bring the cutting-edge of the plane-iron within or without the stock, substantially as described.

2. A router-plane having a post secured to its stock between one edge thereof and an opening therethrough, and a clamp adapted to secure the plane-iron to either the inner or outer side of said post, substantially as shown and described.

3. A router-plane having a post, C, secured to its stock, and having grooves D on its inner and outer sides, respectively, combined with the plane-iron E, the clamp F, and the set-screw G, passing through the clamp and entering one of the grooves, for holding the plane-iron on either the inner or the outer side of the post, to bring the cutting-edge of said iron within or without the stock, substantially as described.

To all whom it may concern:

Be it known that I, JAMES H. LEWIS, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Bench-Tools,of which the following is a specification:

The nature of my invention relates to certain new and useful improvements in hand or bench tools of the plane class, and is particularly designed for use in sticking a bead or molding upon circle or irregular work.

The invention consists in a double-faced plane-stock, in which are removably secured proper heads, carrying the cutting-blades, all as more fully hereinafter set forth.

Figure 1 is a perspective view of my improved device ready for use. Fig. 2 is a perspective view of one of the cutter-heads removed. Fig. 3 is a bottom plan of the same, and Fig. 4 is a longitudinal section on the line x x in Fig. 2.

In the accompanying drawing, which forms a part of this specification, A represent a metallic stock with the plane-faces d, in which are cut proper openings to receive the heads and cutters, hereinafter described. B represent cutter-heads provided with throats. Upon these heads B are removably secured the blades C, which are held in position by means of the plates D and screws b, or in any other suitable manner. Adjustably secured to one side of the heads B are spur-blades E, which cut the straight side of the channel in a beading.

Extending downward from the faces of the heads B are two ribs, F G, the latter of which is oval in longitudinal section, while the inner face of the former has a contour corresponding to the cutting-edge of the blade C, which passes through it, and which produces the molding desired. The faces of these ribs are formed in the segment of a given circle. When the heads are placed in the stock, they are held in position by buttons H, or other suitable means.

In practice, when it is desired to cut a bead or molding upon the inner edge of an arch or circle, the device is placed to its work, so as to cut with the grain, the rib G following the line of the edge of the board, while the blade C and spur-blade E cut the inner half of the bead and channel. To cut the remaining half of the bead, the device is reversed or turned over, and the other head used, as the nature of the work may require, so that the cut will always be with the grain.

While the ribs F G are formed in the segment of a given circle, the device is by no means limited to work in such circle, but can be used in work the radii of which is greater or upon straight work.

The heads carrying the cutting-blades may be constructed to out different sizes, and be interchangable, using but one stock for a set of heads.

What I claim as my invention is —

1. The double-faced triangular stock A, having the cutter-heads B on opposite sides, and the cutters C E, adjustably secured in such heads, substantially as and for the purposes set forth.

2. A bench-tool for cutting circular or irregular moldings, consisting of a double-faced triangular stock, A, cutter-heads B on opposite sides of said stock interchangeably held therein, cutters C E adjustably secured in such cutter-heads, guide-ribs E G, and button H, for holding the cutter-heads in position, all substantially as described and shown.

Be it known that I, JAMES H. LEWIS, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Bench-Tools, of which the following is a specification:

The nature of my invention relates to certain new and useful improvements in hand or bench tools of the spokeshave class for working curved moldings, having for its object to so construct the same as to enable the operator to work with the grain of the timber when it reverses in direction, thus avoiding the expense of a second tool of the same configuration.

The invention consists in providing the segment stock or head with two throats and cutters, inclined toward each other, as is more fully hereinafter set forth.

In the drawings, Figure 1 is a perspective view of my device. Fig. 2 is a cross-section of the same; and Fig. 3 is a vertical longitudinal section, showing the relative position of the centers.

In the accompanying drawings, which form a part of this specification, A represents a metal stock or head, being a segment whose face has the cross-section of the molding that is to be produced. a are throats, inclined toward each other, as shown, and in which are secured the cutter-bits B by means of clamp-plates B’ and screws b, or in any other convenient manner. These bits have a contour at the cutting-edge adapted to produce a molding of the desired cross-section, but are designed to out in opposite directions, so that in working a curved molding either bit may be used to cut with the grain when it reverses its direction, as it necessarily does, thus avoiding the necessity of having a pair of such tools for working each pattern of molding, the one having a reverse cut from that of the other.

The handles are made detachable, as shown; but it is evident that the stock may be provided with permanent or stationary handles, if desired.

What I claim as my invention is —

The bench-tool described, consisting of the segmental head A, having the throats a a and the cutters B, secured in opposite directions in said head by the adjustable plates B’ and screw b, substantially as and for the purpose set forth.

To all whom it may concern:

Be it known that I, JAMES H. LEWIS, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Hand-Tools for Working Moldings, of which the following is a specification:

The nature of my invention relates to an improvement in hand-tools for working moldings, of which there is a great variety of shapes and sizes in a set; and has for its object to so construct the same that one pair of removable handles will fit and can be secured to any of the heads of the various tools.

The invention consists in the peculiar construction of the tool-heads and the handles, as more fully hereinafter set forth.

Figure 1 is a perspective view of one of my improved tools, with one handle detached. Fig. 2 is a longitudinal section through one handle.

In the drawing, A represents a metal stock or head, adapted to receive and have secured to it a bit, B, of the form to produce a given cross-section of molding. The head is cast at each side with a double-flanged rib, a, over which slides a T-slotted head, b, on the inner end of a wooden handle, C, which is secured thereon by driving in a taper key, c.

As hereinbefore stated, a full set comprises a great variety of forms and sizes of molding-tools, the heads alone of which take up but very little space in a joiner’s chest. In the present case one pair of handles will answer for the entire set, which costs less and takes up less space than a set with handles permanently attached.

What I claim as my invention is —

The head A of a hand molding-tool, cast with the flanged ribs a a and the handles C C, provided with the slotted heads b, adapted to be secured to said ribs by a taper key, c, driven in each, substantially as described.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE BUCKEL, of Detroit, in the county of Wayne, and State of Michigan, have invented a new and improved Plane; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of this invention is to provide a plane so arranged that the out may be regulated either in a positive manner or by the pressure of the hand, and that the bit may be raised out of contact with the board being operated on when it is being moved back.

It consists in making the stock in two parts, one part, which supports the bit, being pivoted at the rear end in a longitudinal channel through the other, and provided with a spring and adjusting-screw at the other end, the springs being so arranged as to throw the bit out of contact with the board when the pressure of the hand is removed, and the set-screw governs the amount of such movement.

Figure 1 represents a longitudinal sectional elevation of my improved plane, and
Figure 2 represents a transverse section on the line x x of fig. 1.

Similar letters of reference indicate corresponding parts.

A represents one part of the stock, which is provided with a deep and wide channel in the upper portion from end to end, as clearly shown in fig. 2, and with an opening through the bottom for the plane-bit, as shown at B.

C represents the other part of the stock, which is fitted to the channel in the part A, and pivoted thereto at the rear end, as shown at D.

It is provided with the usual opening for the plane-bit and wedge, and for the escape of the shavings, and at the front end with a spring, E, in a recess in the under face of the same. The said spring bears upon the bottom of the channel, and has a constant tendency to raise the part C away from the said bottom of the channel.

F represents a set-screw, which screws into a nut in the bottom of the channel in the part A, and arrests the upward movement of the part C, due to the action of the spring. The said screw may be adjusted to regulate the said movement of the part C, as desired.

The plane-bit being set by the wedge in the part C as desired, the operator, in using the plane, may, on shoving it forward, so press down the front end of the part C as to cause the bit to take the full cut for which it is set, or, by a lighter pressure, take but a part of the said cut, and when the cut has been made, and the pressure necessary for making the same is relaxed, the spring will throw the part C up so as to take the edge of the bit out of contact with the surface being planed while the plane is being drawn back, thereby protecting the edge from being worn round from that cause.

I claim as new, and desire to secure by Letters Patent —

A plane-stock, constructed of the parts A and C, pivoted together, and provided with a spring, E, and set-screw, F, substantially as and for the purpose set forth.

The above specification of my invention signed by me, this eighth day of July, 1868.

Specification of Letters Patent No. 16,569, dated February 3, 1857.

To all whom it may concern:

Be it known that I, J. F. PALMER, of Auburn, in the county of Cayuga and State of New York, have invented a. new and useful Improvement in Joiners’ Planes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, said drawing being a longitudinal vertical section of my improvement.

My invention consists in the peculiar means employed for adjusting the plane iron, as will be hereinafter fully shown and described, whereby the plane iron may be set with the greatest facility and also be raised free from the work as the plane is drawn back so that the cutting edge of the iron is not impaired thereby.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the plane stock which is constructed of wood and in the usual manner. B is the opening or throat in the plane, and C is a metal plate which is screwed to the back side of the opening or throat, the lower edge of the said plate being beveled and made flush with the bottom or face of the stock. The upper end of the plate is also flush with the upper surface of the stock. The plate C has an oblong recess (a) made in it to receive a spiral spring (b) and also has four guide slots made in it to receive pins (d) which are attached to the back of a plate D which is fitted over the plate C, the plate D being a trifle shorter than the plate C. The plate D has a projection or lip (e) on its back side, said projection or lip fitting over the spring (b) in the recess (a) of the plate C. The projection or lip (e) is notched, or it may be formed of two parts to allow a screw rod E to pass through it. The upper end of the screw rod has a small thumb wheel (f) upon it, and a groove or recess (g) is made circumferentially in the upper part of said rod to receive a fork (h) which is attached to the back side of the plane iron E’. The lower part of the screw rod has a nut F upon it which leans upon the projection or lip (e) on the plate D, and this nut has a screw (i)attached to it, said screw passing through a hole (j) in the plate D, and through a slot (j’) in the plane iron E’, and having a thumb nut (k) on its outer end. The lower part of the plane iron E’ has a cover iron G attached to it.

The upper edge of the nut F is beveled as plainly shown in the drawing, and a rod H is fitted longitudinally in the stock A, said rod having a vertical plate I attached to its back end, the plate I being at the back side of the tote or handle J. The front end of the rod H has a fork (l) formed on it, and when the rod H is pressed forward, it passes through an opening in the plate C and bears upon the upper nut F — a spiral spring (m) is placed upon the rod H, said spring keeping the fork free from the nut F.

From the above description will be seen that by turning the screw rod E, the plane iron E’ may be raised or lowered so as to give it the required “set,” and the plane iron is firmly secured in position or prevented from turning casually. The plate D is connected with the plate C by a guide pin so as to regulate the length of vibration of the plate D and plane iron E’, which are forced downward as the plane is shoved forward by pressing the palm of the hand against the plate I, the rod H being shoved forward thereby and the fork (l) bearing or pressing down the nut F, and consequently the plate D and plane iron E’, said plate and plane iron being kept up above the work or board being planed by means of the spring (b).

By the above improvement the plane iron may not only be set with facility but it is kept up from the work as the plane is drawn backward and consequently the cutting edge of the iron E’ is prevented from being rounded and rendered dull. The plane irons of ordinary planes are soon deprived of their sharp edges in consequence of being drawn backward over the work.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,

The two plates C, D, and plane iron E’ arranged relatively with each other as shown and used in connection with the screw rod E, and rod H as herein described and for purpose set forth.
