To all whom it may concern:

Be it known that I, THOS. D. WORRALL, of Lowell, Massachusetts, have invented certain new and useful Improvements in Planes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in certain devices for securing and regulating the bits in planes, the peculiarities of which will be hereinafter fully described.

In order that others skilled in the art may manufacture and use my invention I will proceed to describe its construction and operation.

In the accompanying drawings which make a part of this specification Figure 1 is a side elevation showing its internal arrangement in dotted lin. Fig. 2 is a plan view of the bit. Fig. 3 is a view of the cap. Fig. 4 is a perspective view of the bottom of the clamp lever. Fig. 5 is a top view of said lever.

In Fig. 1 (A) is the body or stock of the plane. B is a strap attached to the back of the bit — having a screw in its upper extremity — its lower extremity being in the form of a T. (G) is the bit secured to the T strap by means of screws (n n’) seen in Fig. 2. H is the cap having a slot in it as seen in Fig. 3, and secured to the bit by means of a screw (m), said cap being concave as seen in Fig. 1. (D) is a rest attached to the top of the plane. (C) is a clamp lever, being pivoted at (i) and having a slot in its upper extremity (o) seen in this figure being one of the arms of said slot. (F) is a nut, working on the screw on the end of T strap (B), said nut having a groove in it, the groove fitting in the slot on the end of lever C. (E) is a screw passing through rest (D) and serving to operate lever (C).

Fig. 2 represents the bit, (n, n) being screws through it for the purpose of adjusting the T strap, as the plane bit wears. As the bit wears away the screws (n’ and n) may be removed; also, screws (m). Then after slipping the bit down (n’) will enter the place occupied by (n). (n) will occupy hole (x) and m will occupy the hole (n). In this manner I may use a suflicient number of holes and wear the bit entirely up, which cannot be done in the ordinary plane secured with strap.

Fig. 4 shows the bottom of clamp lever C — the T arms of lever C slip in between jaws (a) and slide on flanges (c), being clamped by said flanges when the lever is operated above by means of screw (E).

Fig. 5 shows a top view of the clamp lever with its slot for receiving the tap or nut (F).

In operating this plane the bit is first secured to the T strap, then the cap may be adjusted to its proper position on the bit, and the strap inserted into position in the plane stock — the lower extremity of the T strap enters the jaws of clamp lever C and its arms slide on, and are secured by flanges (c) — the groove in nut (F) being adjusted in slot into top of lever C the screw (E) is operated and the bit firmly secured.

The advantages of clamp lever C are very readily perceived (the lever may be made any desired or convenient length and the power obtained by it may be very great) for there is no known process by which a plane bit may be so securely bedded as by this — this lever operates upon the bit at two important points for bedding it — it draws the bit in at the bottom, with the power, and in a manner that can be done by no other means. The easy adjustment of the plane by means of lever C and screw (E) gives it advantages not possessed by other planes.

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

I claim —

The employment of the clamp lever C for securing and bedding the bit, in the manner herein fully set forth and described.

In testimony whereof I hereunto set my hand.

METHOD OF ATTACHING ADJUSTABLE HANDLES TO JOINERS’ PLANES.

Specification of Letters Patent No. 18,312, dated September 29, 1857.

_________________

To all whom it may concern:

Be it known that I, THOS. D. WORRALL, of Lowell, Massachusetts, have invented certain new and useful Improvements in Movable and Adjustable Handles for Molding-Planes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in certain devices for attaching and adjusting the handles on molding planes, the peculiarities of which will be hereinafter described.

In order that others skilled in the art may manufacture and use my invention I will proceed to describe its construction and operation.

In the accompanying drawings which make a part of this specification Figure 1 is a side elevation. Fig. 2 is a plan view of plate, D, Fig. 1. Fig. 3 is a view showing the slotted face of rectangular strap C. Fig. 4 is view of the nut, button and screw, for attaching plate D to the stock or wood part of the plane.

In Fig. 1 A is the stock or body of the plane, (B), is the handle, (D), is a slotted cap plate, resting on the top of the plane as seen in this figure. (C), is a rectangular strap of metal, the handle (D), being attached to one arm, the other extending several inches in front of the handle, is slotted, as seen in Fig. 4. (F), is a nut, with jaws as seen in Fig. 3. (G), is a button on the back of nut (F). (E), is a thumb screw passing through plate (D), and entering nut (F) as seen in Fig. 3.

Fig. 2 represents the slotted plate (D), (B), is a square shaft, passing through slot in strap C, (c), is a screw on the end of shaft b. Nut (a) in Fig. 1 passes over this screw and attaches plate (D), to strap (C).

In attaching this handle to planes, I first cut a groove in the top of the plane and a mortise in the side, the groove and mortise meeting form a T-shaped slot. The nut, F, fits in the body of this slot and the flanges formed by the projecting of the button beyond the sides of the nut fit in the arms of the slot. Plate D fits on top of the plane, between the arms, or jaws of nut, F, and over the slot, screw, E, passes through the slot in cap plate, D, and enters the nut, F, and secures the handle firmly to the plane. By means of the slot in cap plate D, the handle may be made to assume the position seen in Fig. 1 or strap, C, may lit up snugly against the plane as is the general manner of using it.

Strap C it will be seen is slotted for the purpose of adjusting the handle, elevating or lowering it as circumstances or convenience may require; the handle when placed at any desired position may be secured by means of the nut, (a). This adaptation of the handle to the top or bottom of the plane is particularly desirable in some instances. If the bit is set for cutting a very thin shaving the handle may be at the top or above the top of the plane, but if set for cutting a heavy shaving the handle should be as low as possible in order to have the power in a line with the work, so that the plane will not tilt but move steadily.

One of the chief advantages of my movable handle is that it does away with the necessity of making handle to my planes. They may thereby be aiforded at a much cheaper rate. This handle is so easily adjusted on the plane that but little time will be consumed in changing from one to the other.

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

1. I claim the combination and arrangement of cap plate D, screw E, nut F, and T slot o, in the plane for the purpose of providing and securing a movable handle to planes.

2. I claim the arrangement of cap plate D, slotted strap C, and screw a, for the purpose of adjusting the handle vertically when desired by the operator as set forth and described.

To all whom it may concern:

Be it known that I, THOMAS D. WORRALL, of Lowell, in the county of Middlesex and State of Massachusetts, have invented an Improved Bench Plane or Jointer; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which —

Figure 1 is a top view of the same. Fig 2 a side elevation o it. Fig. 3 a vertical, central, and longitudinal section of it. Fig. 4 a horizontal section of its cutter holder and clamp.

In these drawings A denotes the body or stock of the plane as made of wood and having a handle B projecting upward from it, such part A generally being about one-half or less than one-half the thickness of stocks for bench planes or jointers as ordinarily made. The said stock is provided with a separate metallic cutter holder C, which is placed on its top and fastened to it by means of screws as seen at a, a. This cutter holder formed as shown in the drawings, is furnished with a slide clamp D, made so as to embrace a dovetailed projection ln, extending from the rear side of the cutter or plane iron E, as shown in the drawings. Such slide is provided with a slot f, for the reception of wedges F, G, which act against one another, the rear end of the slot and a shoulder c formed in the cutter holder. By driving up these wedges the cutter is drawn firmly down upon its seat d, formed in the holder and does not depend on the wood of the plane iron to enable it to be held in place.

By my construction of the plane important advantages are gained. It may be made lighter than ordinary planes of the kind ; its cutter is more firmly held in position ; its devices for clamping the cutter are compact and disposed in convenient positions for the carpenter to operate them as occasion may require. Furthermore, they are well protected both by the handle and the cutter so as not to be liable to be disturbed or disarranged except as occasion may require.

What I claim is —

The improved manufacture of carpenter’s bench plane or jointer as made with its handle, its wooden stock to which said handle is atlixed, and a separate metallic cutter holder, and cutter clamping devices arranged together substantially as specified.
In testimony whereof I have hereunto set my signature.

ADJUSTING THE BITS OF CARPENTERS’ PLANES.

To all whom it may concern:

Be it known that I, THOMAS D. WORRALL, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Carpenters’ Bench-Planes; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which —

Figure 1, is a top view. Fig. 9, a side elevation. Fig. 3, a vertical and longitudinal section, and Fig. 4, a horizontal and longitudinal section of one of my improved bench planes, the latter section being taken through the pinion gear by which the plane-iron or cutter may be elevated or depressed within the throat of the stock.

In the said drawings, A, denotes the stock, B, the cutter or plane-iron, and, C, the throat of the stock.

In order to hold the plane-iron within the stock, I employ a clamp or piece of metal, D, made so as to embrace a dovetailed rack bar E, fixed to the rear side of the cutter, B, as shown in Figs. 3 and 4. The clamp is arranged within a cavity or recess, F, formed in the stock and leading out of the rear side of the throat thereof. A female screw, a, is made through the rear part of the clamp and so as to receive a male screw cut on the end of a long rod, G, which extends backward through the stock and has a hexagonal head, c, as shown in the drawings. The rack, E, is provided with teeth on its rear side to cooperate with a pinion, H, arranged and made to turn within the clamp, and to have its shaft, I, extended laterally through the plane stock and formed so as to receive a key, by which it and the pinion may be put in rotation for the purpose of regulating the distance of the cutting edge of the plane-iron relatively to the lower surface of the stock. Such distance having been obtained, the clamp, D, is to be brought into action or to be drawn backward so as to act upon the dovetail of the rack and so as to draw the plane-iron firmly against the rear face or side of the throat and hold said plane-iron in its proper place.

From the above it will be seen that we not only have a means of clamping the plane-iron, but of readily adjusting it in the stock. Furthermore a cap iron, K, is applied to the plane iron for the purpose of enabling it to plane cross grained stud, a top view of said cap and the plane-iron being represented in Fig. 5. Instead of making this cap straight from end to end, or with its under surface a plane surface, as it is usually made, I give to it a curved form throughout its entire length as shown in Fig. 3, and provide the cap with a slot, L, arranged in it as shown in the drawings. A clamp screw, M, extends through the slot and into the plane-iron, the same being for the purpose of confining the cap to the plane-iron. In order to regulate the longitudinal movement of the cap iron, or plane-iron I apply to the cap and plane-iron an adjusting screw, as shown at N. Thus it will be seen that the plane stock is not employed as a bearing for the device by which the cap is held to the plane-iron, such device being entirely independent of the stock.

By making the cap curved in manner as described its lower end may be forced down into perfect contact with the upper surface of the plane-iron, and will not spring there from so as to admit shavings or pieces of wood between it and the cutting edge of the plane while it is in use. It is well known that when the cap is made perfectly flat it is liable to be raised off the iron by slivers or chips which may become wedged between their lower ends, the same serving to interrupt the proper action of the cap. By making the cap in my improved manner and by applying a clamp to it so as to be independent cf the stock in the way above described, I am not only able to effect the proper fixation of the cap iron, but can adjust the plane iron or move it up and down without disturbing the said adjustment of the cap thereon.

I claim —

The arrangement of the rack and pinion and the clamp so that while the pinion is placed within the clamp, the rear or dove-tailed sides of the rack bar shall serve as bearings for the clamp to work against.
In testimony whereof I have hereunto set my signature this eighteenth day of September, 1856.

To all whom it may concern:

Be it known that I, THOMAS D. WORRALL, of Boston, in the county of Suffolk, and State of Massachusetts, have invented an Improvemnt in Carpenters’ Molding-Planes; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which —

Figure 1, is a top view, and Fig. 2, a side elevation of a plane containing my improvement. Fig. 3, a vertical, central and longitudinal section of it. Fig. 4, a side view of the clamp to be hereinafter described. Fig. 5, a front view of said clamp. Fig. 6, a front view of the plane iron as removed from its stock.

The nature of my invention consists in an improved arrangement of clamping mechanism, or that used for retaining the plane-iron within the throat of its stock. In the said drawings A, denotes the stock; B, the cutter or plane-iron; and C, the throat of the stock.

In order to hold the plane iron within the stock, I employ a clamp or piece of metal, D, made to extend partially around it or embrace it and to be arranged with respect to it as seen in the drawings, the said clamp being placed in a recess a, leading out of the rear and upper part of the throat and made of a suitable size to allow the clamp to be moved backward far enough to draw the plane iron closely against the surface of the throat. A female screw, b, is formed through the rear part of the clamp and so as to receive a male screw, C’, out on the end of a long rod E, which extends longitudinally through the stock A and from its rear end to the clamp and has a shoulder, d, and a flat head or handle, e, as seen in the drawings. By turning the rod so as to cause the screw, C’, to enter the clamp, the said clamp may be drawn down closely upon the plane-iron so as to confine it closely or firmly in the throat of the stock.

By my arrangement of the confining contrivances, the throat of the plane-iron is not obstructed by any device, extending across it transversely, the plane cutter being held in place by the backward draft of the clamp and the bearing of the rod of the shoulder E, against the rear end of the plane stock.

I do not claim merely holding the plane or cutter in place in its throat by a wedge, screw, or equivalent device forced into the throat and across it and against the plane-iron, but

What I do claim is —

The arrangement of the clamp, D, and the screw rod E with respect to the plane cutter and its stock substantially as described.

In testimony whereof, I have hereunto set my signature this twenty-seventh day of February A. D. 1856.

MULTIFORM MOLDING-PLANE.

Specification of Letters Patent No. 11,635, dated August 29, 1854.

_________________

To all whom it may concern:

Be it known that I, THOMAS WORRALL, of Mount Holly, in the county of Burlington, in the State of New Jersey, have invented an Improveinent in Carpenters’ Molding and Grooving Planes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the application of slides, by means of plates and screws) to the plane which will render that plane capable of working all kinds of moldings rabbets and grooves.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. I make a dovetail and groove in the face of a plane, then screw or pivot a plate to the side of that plane, with holes through which screws may pass to secure the slide, I now make a slide of any pattern and put into the groove and dovetail which I secure by means of the screws which pass through the plate.

Figure 1 in the drawing is the end of the plate. Fig. 2, shows the end of the plane dovetailed and groove on the face. Fig. 1 is securely screwed or riveted to Fig. 2, at a, which forms Fig. 3, and thus forming the opening for the slide as seen on Fig. 3, at b–b. C, D, E, F are slides made to fit into this opening. Fig. 5 is the guide to a common plow, or sash filleter. Fig. 4, is the side of a plane, showing the brass, or iron plate.

g, g, on Fig. 5, should pass through the holes g, g, on Fig. 4. Now take slide C, and put it into the plane at b, b, as seen on Fig. 3 and you have a sash filleter complete; then take out slide C, and put in slide D, and you have a plow plane complete.

The stop on the side of the plane marked, h, is to regulate the depth of groove by the plow, or of the rabbet by the filleter. The two planes thus formed, are the only two requiring either the guide Fig. 5, or the stop, h. Let these be taken off, and in the place of slide D, put in slide E, and you have a common bead plane, remove that slide, and put in slide F, and you have a molding plane, and so on with every conceivable kind of plane. The only thing required to make as great a variety of moldings &c. as you please, are a new slide and a new iron to each.

The slides are made firm to the bed of the plane, by screws as seen on the plate on Fig. 4, and marked i, i, i. These pass through the plate into another plate on each of the slides, (which plate is denoted by the thick black mark on the drawings at j) and are thus screwed firmly to the plane, and if additional firmness should be required, which may be the case when the plane is required to make very wide moldings, it may be obtained by passing a, screw through the plane at k, as seen on Fig. 3, into a plate denoted on the drawings by the thick black mark at l in slide C and thus screwing the slide more firmly against the base of the plane at m, on Fig. 3.

What therefore I claim as my invention, and for which I desire security by Letters Patent, is —

The slide attached to a plane, by means of plates and screws, which will make that plane capable of working all kinds of grooves fillets and moldings.
