TO ALL WHOM IT MAY CONCERN:

Be it known that we, F. SMITH and I. CARPENTER, of Lancaster, in the county of Lancaster, and State of Pennsylvania, have invented a new and useful Improvement in Joiners’ Planes; and we 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 nature of our invention relates to improvements in joiners’ planes, whereby it is designed to render the stocks less liable to warp, to regulate the weight of the same, to provide for a more perfect delivery of the shaving, adjusting the some to be used as a single or a double plane, and adjusting the mouth, so as to govern the width of the same for the passage of the shaving.

And it consists in constructing the stock partly of iron, substituting, for the tapered notches of wooden stocks for holding the tightening-wedges, set-screws for holding the wedge, which is made of metal, and provided with an additional tightening-screw in its upper end, which works against the face ofthe plane-bit, or into a swivel-nut which slides in the slots of plane-bits, as ordinarily constructed, and providing a wooden wedge at the back side ofthe plane-bit, as will be more fully described on reference to the accompanying drawings, wherein —

Figure 1 represents a plan view of our improved plane.
Figure 2, a central section ofthe same on the line x x of fig. 1.
Figure 3, a plan view of a part of our improvement applied to plane-bits, having the ordinary slot in the same; and
Figure 4 a section on the line y y of fig. 3.

Similar letters of reference indicate corresponding parts.

A represents the wood part of the stock, and B the iron portion of the same, which are secured together by the screws d d.

The part B may-be made of cast iron, and of different thicknesses, as may be desired to govern the weight of the plane.

The handle and knob may be secured to the part B in suitable sockets provided for them by the screws d d.

The part B is provided with lugs, a1 a1, through which set-screws, a2 a2, are arranged to hold the cap.

C represents a metal cap or wedge, provided with a set-screw, b, by which it may be, if desired, raised at its upper end from the bit D.

The said cap is provided with a raised portion, C’, in advance of the set-screw b, which rises by a gentle curve from the wedge portion of the same, so as to prevent the shavings from clogging against the screw.

When a plane-bit is used without a slot, as in figs. 1 and 2, we use a set-screw arranged as therein shown, but to adapt our improved tightening-wedge to plane-bits of the old construction, having the slot for set-screws as ordinarily constructed, we attach, to the ends of the set-screws, swivel-nuts, e, having slots in two edges of the same, which admit it to slide within the slot in the plane-bit, by taking the edges of the bit forming the side walls of the slot in the latter into the slots in the nut, the nut being of the proper size to be admitted through the enlarged portion of the slot in the plane-bit.

E represents a wedge, which may be made of wood or metal, and arranged in the bottom of the mouth of the stock under the plane-bit, and held there by the set-screw e1 passing through a slot in the said wedge, whereby it may be adjusted within the mouth ofthe stock.

The face of the wedge next the plane-bit is provided with a recess, e2, to admit the nut e of the set-screw.

The under side of the upper end of the metallic wedge C is provided with a recess, f, (see fig. 4,) when the nut e is used.

By the use of our improved wedge, the same plane-bit may be used for a double or single bit.

When used as a single bit, it may be applied as shown in fig. 2, and when used as a double bit, the set-screws a2 may be withdrawn, so that the wedge may be moved down sufficiently near to the edge of the bit to serve the purpose of a double bit.

By adjusting the upper end of the wedge by a set-screw, b, the width of the mouth may be adjusted to suit the different requirements of different kinds of work, or of different kinds of wood, or may be made of uniform width from bottom to top.

The same may be also adjusted by the wedge E to some extent, but the more important function of the wedge E is to govern the width of the throat at the cutting-edge of the bit, as at k, as will be readily understood.

In adjusting the wedge to the bit, when constructed as shown in figs. 3 and 4, the lower end of the wedge is placed at the right position with reference to the cutting-edge of the bit, and the thumb-screw turned to the left until the upper end of the wedge is screwed tightly to the bit. They are then inserted in the stock, the set-screws a2 adjusted to their right positions, when the set-screw b is turned in the opposite direction, and the wedge forced out against the set-screws a2.

The metallic part, B, of our stock may be taken off from a worn-out wood stock, and readily applied to a new one, or old plane-stocks of ordinary construction may be readily fitted to be attached to it.

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

1. The adjustable cap, provided with the guard in front of the set-screw b, substantially as and for the purpose described.

2. The set-screws a2 in the lugs a1, arranged to clamp upon the adjustable wedge C, as herein shown and described for the purpose specified.

I. CARPENTER.

To all whom it may concern:

Be it known that I, EMANUEL W. CARPENTER, of Lancaster city, in the county of Lancaster and State of Pennsylvania, have invented a new Improvement in the Regulation of the Mouths in Planes so as to Enlarge or Diminish the Same and for the Preservation of a Close Mouth in Planes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification.

The object contemplated by my improvement, is the regulation of the mouth in planes, so as to enlarge or diminish the same; and for the preservation of a close mouth in planes.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, as follows, viz.:

A is a bench plane with the improvement.
B represents the wedge or key, with a. longitudinal aperture, over which is a scutcheon, inlaid with a similar aperture but not so wide, leaving room for the head of the screw to rest upon, (or by a washer or plate, as shown in the key in the double bit) for the purpose of fastening the key to the upper part of the bed of the plane, under the bit, by means of which the mouth of the plane can with ease be tightened by gently driving the key downward, or with equal ease enlarged, by drawing back the same.

The improvement is applicable to all kinds of planes.

The wedge or key in the double-bit plane is similar to that in the single-bit, with the exception of the opening left below the longitudinal aperture to receive the head of the screw that fastens the cap to the bit. A washer or plate is here used instead of the scutcheon as in the single-bit, to show its application, but the scutcheon is equally applicable.

C, is the molding plane, with the improvement. The wedge or key in the molding plane, is shaped like the bit, but the key part somewhat longer, and tapered down to the face of the plane; the bed of which, is out to suit the bevel or shape of the key B. The screw is here inserted at the upper side of the plane, to keep the key B, permanent while setting the bit.

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

The regulation of the mouth in planes, so as to enlarge or diminish the same, and for the preservation of a close mouth in planes, as herein described, by a wedge or key (B)
being placed under the bit, and fastened by a screw.

METHOD OF CONSTRUCTING THE SCREW-ARMS FOR ALL KINDS OF PLANES REGULATED WITH SCREW-ARMS.

Specification of Letters Patent No. 594, dated February 6, 1838.

_________________

To all whom it may concern:

Be it known that I, EMANUEL W. CARPENTER, of the city of Lancaster, State of Pennsylvania, have invented a new and useful improvement in the mode of regulating plow-planes, tongue and grooves, fillisters, and such other planes as are regulated by screw-arms; and I do hereby declare that the following is a full and exact description.

That part of the arm to which the fence is attached (marke E in the drawing) I make of hard wood about an inch thick, one inch and seven eighths broad and about two and three fourths inches high. A hole is bored near its upper edge large enough to receive the screw part of the arm (letter F) which is kept to its place by means of a groove cut around the screw near its head and by a broad dowel (letter I) let into this groove from the top of the first described piece. Two screw holes are made through the body of the plane one near each end to receive the screw arms or male screws (F) ; then by turning these screw arms, by applying the power to their heads, you regulate the fence with the body of the plane, with ease and exactness, but to hold each more firmly to its place when regulated, a screw nut (G) is placed on each arm on the left side of the body of the plane and a larger one (H) on the right side and by screwing these up when the plane is set, to wit, by bringing the two on the right side close to the body of the plane and the two on the left side close to the upright (E) part of the arm, the fence is kept firm to its place during the working of the plane. A 2d method : In this arm, the dowel may be omitted, the screw nut (G) being brought close to the first described piece E and pinned fast through the screw arm. A 3d method is by having the arm to which the fence is attached, E, in two pieces, the lower piece to extend up to the center of the arm. A hole is made, one half in each of these pieces, a groove is cut, round, in the head of the screw arm sufficiently large to admit these pieces into it, these pieces are then fastened together with two iron screws. A 4th method differs from the last described, in boring the hole half through on the left side with one bit end and on the other with a larger bit and cutting the groove in the screw arm to fit this hole and then fastening the two pieces together with iron screws as in the last, this one like the first, has also a screw nut on the arm F to keep this part more firm.

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

The method of making and applying the screw arms to the plane as described, which regulate the fence with great ease and accuracy and give it an increased firmness over all others now in use.
