IMPROVEMENT IN CARPENTERS’ PLANES.

To all whom it may concern:

Be it known that I, ELLIOT G. STORKE, of Auburn, in the State of New York, have invented certain new and useful Improvements in Carpenters’ Planes, of which the following is a specification:

The object of my invention is to provide a simple, easy, and exact method of adjusting the bits or cutters of carpenters’ planes.

Figure 1 is a longitudinal vertical central section of an ordinary metallic plane embodying my improvements. Fig. 2 is a perspective view of the same with the bit removed.

Similar letters refer to the same parts in the respective figures.

A is the bed-plate for the support of the bit. Near the transverse center thereof is placed the sliding plate B, running in ways cut in the said bed-plate, having in its upper face an oval recess, C, for the reception of the cap screw heads of double plane-irons. From the lower face of the said sliding plate projects the shank-nut D, so far below the bed-plate that when the screw E is passed through its lower end, on a line parallel with the pitch of the plane-iron, a large thumb-wheel, F, can be mounted upon the upper end thereof without colliding with the plane-iron above or the plane-body below. That thumb-wheel is supplied with six arms, H, equally spaced upon its hub, giving as many distinct and conveniently-located levers, by which the workman can easily revolve the said wheel and move the parts with which it is connected. From the lower face of the bed-plate A, and near its upper end, projects the shank-bearing for the adjusting-screw G, of the same length as the shank-nut D, and in line therewith. Through the lower end of the said shank-bearing passes the upper end of the screw E into the hub of the said thumb-wheel, the former being shouldered where it joins the inner face of the latter, and the wheel, being pinned to the screw, carries the latter with it. Now, by revolving the thumb-wheel in the shank-bearing G, the shank-nut D and the sliding plate B are raised or lowered at pleasure, giving to the cutters a corresponding movement, and securing any desired thickness of shaving.

It will be seen from the foregoing description that my invention consists, mainly, in devices by which plane-bits are adjusted by a single direct-acting screw, operating through the medium of the cap-plates of double irons. The two shanks or lugs D and G, the screw E and sliding plate B, and the thumb-wheel F, with its arms H, are the devices employed for this purpose.

By projecting those lugs far below the bed-plate A — that is to say, far enough to carry the axis of the thumb-wheel to the center, or thereabout, of the space between the plane-iron and plane-body — I am enabled to use upon the screw E a large thumb-wheel supplied with the lever-arms H, and I thus gain all the power necessary to move the bits easily by the single screw E. The arms H, lying both to the right and left of the plane-handle, are easily and conveniently operated by the workman, either by the thumb from the left, or the fingers from the right, or both conjointly, without removing the hand — a device possessing decided conveniences over the circular thumb-screw heads heretofore in use for the same purpose.

I am aware that screws have been applied directly to plane-irons for their adjustment, but not in that way to the cap-plates of double irons, nor to their screw-heads. In the latter application the maximum movement of the operating-screw is less than one-half inch, in the former fully two and one-half inches, and a special attachment must be made to the cutter in which to work the screw; but that application, so far as I am informed, has been abandoned for the lack of power to operate the bits, and in its stead various combinations of single levers, or levers and cams operated by screws, have been resorted to, the objection to which is the increased cost of construction, and the greater liability to derangements and backlash.

I am also aware that various devices for adjusting plane-bits have been applied to the cap-plates or cap-screw heads of double plane-irons, but none, it is believed, in which that adjustment has been effected by a single screw without other intermediate devices.

The simplicity, durability, and practical efficiency of the devices herein described will, it is believed, be clearly apparent, as well as their superiority to those hitherto employed for the same purpose.

Having described my invention, I shall state my claim as follows:

The direct-acting or adjusting screw, having a thumb-wheel formed with lever-arms, as described, in combination with the bed-plate, having an elongated shank-bearing, and the sliding socket-plate, having an elongated shank-nut, all substantially as and for the purposes shown and set forth.

In testimony whereof I have hereunto signed my name this 3d day of February, A. D. 1876.

IMPROVEMENT IN CARPENTERS’ PLANES.

To all whom it may concern:

Be it known that I, ELLIOT G. STORKE, of Auburn, New York, have invented certain new and useful Improvements in Carpenters’ Planes, of which the following is a specification:

My improvements relate to setting and fastening the bits of planes, and also to means for giving to bench-planes a metallic and adjustable throat-piece.

The nature of my invention can best be explained by reference to the accompanying drawings, in which —

Figure 1 is a longitudinal vertical central section of a plane embodying my improvements. Fig. 2 is a perspective view of the same with the plane-iron fastener and bit removed. Fig. 3, 4, 5, are views of detached parts hereinafter described. The plane represented is one with a metal top and wooden face.

A is the lever by which the bit is set or adjusted to cut fine or coarse shavings, and Y its upward-projecting point; B, the standards which support the upper end of the bit B’; C, the journals of the said lever A, said journals resting in bearings cut in projections on the front of standards B, in which bearings the journals have a lateral or end-wise play. L L are two grooves cut on the interior opposite sides of the frame or plane-body, for the reception of lugs D’ of the plane-iron fastener D, shown in perspective in Fig. 3. The lugs are on the sides of the fastener and near its longitudinal center, and at its rear end is the thumb-screw. F is the cap and G the screw of an ordinary plane-iron, the screw-head being countersunk at at to receive the globular point Y of the lever A. s is a blank screw-hole tapped in the cap, into which the said cap-screw can be removed when it becomes necessary, by the wearing away of the wooden face of the plane, if such be used, to raise the cutting-iron.

The devices thus far described for fastening and setting the bit are operated as follows: The lever A is placed in its bearings in the standards B; the cap is screwed in the usual way upon an ordinary plane-iron, and the recess in the screw-head laid upon the point Y. When so laid the bit is upon its bearings, and the point Y fits neatly the recess a in the cap. The lugs D’ of the fastener are now placed in the grooves L L and the thumb-screw E tightened, which binds the bits to its bearings with more or less firmness, according to the pressure given by the screw.

The lugs D’ of the plane-iron fastener are introduced into the inclined grooves L L at the lower and open ends of the latter. The upper ends of said grooves are shouldered or closed, as seen in the drawing. The thick heel of the plane-iron, when drawn back, tends to force the fastener upward. This movement in time has the effect of smoothing the surfaces of contact of the lugs and grooves, thus increasing the liability of the fastener to work upward in the grooves. To remedy this difficulty l shoulder or close the grooves at their upper ends, as shown, thus preventing liability of the fastener becoming disengaged from the grooves. The long arm of the lever A is immediately under and within easy reach of the fingers of the workman, while grasping the plane-handle, and by raising or lowering it the adjustments of the bits are quickly and easily made, under the firmest pressure of the screw. I so construct the lever with a central hub bearing accurately-turned journals at its ends, with the spherical point Y rising upward from its center, and from which extends the long arm toward the plane-handle, that all its parts, being in one piece, are wrought with much greater facility, accuracy, and economy, and placed and maintained in position more easily and firmly than if separate pieces were employed in its construction, and so also that its journals have a free and accurate lateral or sidewise movement, by which the upper end of the bit, when fastened, can be so pushed to right or left as to square its cutting-edge with the face of the plane. By connecting the spherical point Y with the screw-heads of double plane-irons, I obtain not only a very cheap, but a very efficient means of adjusting them, for these screw-heads always maintain, practically, the same position, relatively to the cutting-edge of the bit, and can be countersunk at a merely nominal cost. The sweep of the long arm of the lever A carries the point Y through a sufficient arc to give the required adjustment to the bit, and a leverage of such power that the adjustment is easily made.

As this device for fastening and setting the bits of planes can be applied with equal facility to metallic planes, and to those having metallic tops and wooden faces, I provide for the wearing away of the latter by tapping the said cap a second time at s, into which, as the face of the plane wears away, the said screw can be removed, and in that way the bit can be worked higher up.

The metallic and adjustable section or throat-piece is shown detached in Fig. 5. I is the flat surface thereof, accurately milled on its sides to fit ways or guides out on each of the inner sides of the said frames or plane-body, on its upper face and immediately forward of the bit. K is the vertical portion thereof, which, when the said section is in place, projects downward to and directly in front of the bit, as seen in Fig. 1, having the same width as the latter, and its lower edge precisely in line with the face of the plane, thus forming a metallic throat-piece to keep down the grain, and to prevent wear from the friction of the shavings. To hold the said section in place a hub, M, is formed on the upper front face of the plane, so placed thereon as to enter along oval aperture, b, in said section, when the latter is in position. The said hub is tapped to receive a screw cut on the lower end of the shank of the knob N; or, if a knob be not used, the section may be held in place by a thumb or other screw, such screws having suitable washers. By driving the said screw the section is firmly held at the point desired, and loosened by a backward turn thereof. The said section is applied to an ordinary wooden plane by screwing a nut in the upper front face thereof, at the point occupied by the said hub M, as above described, and employed for the same purpose; or a plate may be formed to screw thereon, containing the hub M and the ways to guide the said section, effecting precisely the same edect in wooden planes as in those of iron, or in those with wooden faces.

As this section and throat-piece can be applied with facility and cheapness to common wooden planes and to iron planes at much less cost than the prevailing method of bedding the section in the face of the plane, its utility and importance must be manifest. No plane works well unless that part of the face in front of the bit is true and perfect, so that it will press down the wood as the bit cuts it; and in line work that pressure must be very close to the edge of the bit. Now, in wooden planes, the friction of the shavings, and of the work over which they are moved, very soon wears them away at the throat, so as to compel their frequent refacing, and supplying temporary wooden throat-pieces. My device gives to them at once a metallic throat-piece, which will permanently endure the necessary friction to which it is exposed, and also an adjustable one, by which the plane may instantly be adapted to fine or coarse work.

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

1. The setting-lever, provided with journals which rest in fulcrum-bearings on the front of the plane-iron standards, and have lateral play in said bearings, substantially as shown and described.

2. The combination, with the conntersunk or recessed screw-head of a double plane-iron, of the journaled setting-lever engaging with its shorter arm the recessed screw-head, substantially as herein shown and set forth.

3. The metallic section or throatpiece applied to and movable and adjustable upon the upper face ofthe plane-body, as described, and formed with a vertical portion projecting downward through the plane body to form the front of the throat, substantially as set forth.

In testimony whereof I have hereunto signed my name this 26th day of December, A. D. 1874.
