To all whom it may concern:

Be it known that I, JOHN A. KEISER, a citizen of the United States,and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Cabinet-Scrapers, of which the following is a specification, reference being had to the accompanying drawings forming a part hereof.

My invention relates to an improved cabinet-scraper.

Figure 1 is a top plan view of my improvement. Fig. 2 is a bottom plan view of the same; Fig. 3, a section on line x x, Fig. 1; Fig. 4, a perspective view of the pivoted clamp; Fig. 5, a section on line z z, Fig. 1.

A A’ represent the handle of the scraper. The stock of the tool is composed of the following parts.

B b represent the face of the scraper; C, a slot separating the faces in which the cutter is set.

D represents a ledge, against which the cutter c is clamped. This ledge is rigidly attached to the face B, the parts forming an L, as shown in Fig. 3. F represents the ends of the stock, from which the handles A A’ spring, as shown in Figs. 1 and 2.

E e represent arms forming a part of the end plates of the stock F, for firmly holding face b rigidly in a plane parallel with face B.

G represents a pivotal clamp for clamping the knife c against the ledge D. This clamp is suspended on pivots a to the end plates ofthe stock F, passing through ears d of the clamp G.

H represents a lever-arm extending upward a considerable distance above the pivots of ears d.

I represents a set-screw tapping through the arms H, the point of which bears against the ledge D and forces the lower edge of clamp G against the cutter c at its lower end, and firnily clamps it against D.

This tool is very cheap, strong, and efficient. The cutter c works clear to the ends of face B b, and is a decided improvement over the tool shown in Letters Patent granted Samuel C. Tatum & Co., my assignees, June 10, 1884, No. 300,266, and other tools for the same purpose hitherto used.

Instead of screw I, a cam may be used to operate the clamp, and would be the equivalent therefor.

I do not broadly claim a stock having rigid faces separated by a slot, and the front face strengthened by arms forming part of the ends of the stock; nor do I claim, broadly, a cutting-bit attached to an oscillating plate adjustable by a thumb-screw and spring; nor a spokeshave having a bearing-surface in front of the cutter applied by a lever having an adjusting-screw for regulating the width of the month, the thickness of its cut, or the shaving; and I do not broadly claim the bearing-surface of a stock provided with a ledge or flange serving as a bearing for the cutting-bit.

I claim —

1. A cabinet-shave consisting of the stock F, rigid faces B b, separated by slot C, the part b being braced by arms E e, forming part of the end plates of the stock, ledge D, and cutter c, clamped against the ledge, substantially as described.

2. A cabinet-shave consisting of the stock F, rigid faces B b, separated by slot C, ledge D, and clamp G, pivoted to stock F, and adapted to clamp a cutter, c, against the ledge D, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand.

To all whom it may concern:

Be it known that I, JOHN A. KEISER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Bench-Planes, of which the following is a specification.

This invention relates to improvements in benoh-planes; and it has for its object to provide novel and efficient means for adjustably connecting the cutter with the plane-stock. This I accomplish in the manner and by the construction and combination of devices hereinafter described and claimed, reference being had to the accompanying drawings, illustrating my invention, in which —

Figure 1 is a side elevation of my improvement. Fig. 2 is a cross-section on line x x, Fig. 1. Fig. 3 is a perspective view of the side gage. Fig. 4 is an enlarged detail view of the side gage and fastening-clamp. Fig. 5 is a detail view of the clamping device.

A represents the base of my plane-stock; B, the side of the stock, G, the handle; c, the ledge on which cutter a rests and is secured.

D represents the cutter-clamp, which is operated as follows:

E represents a bell-crank lever, which is pivoted at e and the side of the stock B.

b represents the arm of bell-crank lever, to which the clamp D is pivotally attached.

b’ represents a shoulder or stop for limiting the pivotal movement of clamp D on arm b, to force the points d down upon the cutter a.

The crank E is made to have two bearing-points, d d. The clamp D is raised and lowered by the movement of the bell-crank lever E. When occupying the position shown in Fig. 1, the clamp D is forced down upon the cutter a, and holds it securely in position. When it is desired to readjust the cutter a, or to take it out, the bell-crank E is lifted up, which moves the points of the clamp away from contact with the cutter a, and allows it to be removed or adjusted.

F represents a mortise or opening pierced through the side of the stock B.

G represents the adjustable side gage, which is provided with a mortise, g, through which is inserted a clamp, and a slot, h, which slides over the shank of the clamp, for allowing the gage G to be adjusted.

H represents a headed clamp-bolt.

I represents the shank of the same, over which the slot h of the gage G moves up or down for its adjustment.

K represents a cam or eccentric lever pivoted to the shank I, which, when turned up, bears against the face of the gage G, securely clamping it in position by drawing the head of clamp-bolt H against the side of the plane-stock, and the cam clamping or pressing against the outside of the gage G. When the lever K is turned down, gage G is released, so that it may be adjusted to the desired height. The mortise g is sufficiently large to allow the eccentric-lever K to pass through the opening g, for the engagement of the slot h, upon the shank I of the clamp-bolt. This device may be readily adjusted and attached to, or removed from the plane. By this method of constructing the side gage the metal of the plane-stock is but slightly weakened, and a very convenient detachable gage is obtained.

I Claim —

In combination with the plane A B, having the ledge c, and the bell-crank E, pivoted to the side of the plane and pivotally connected to the cutter-clamp D, said bell-crank being provided with stop b’, substantially as described.

In testimony whereof I have hereunto set my hand.

To all whom it may concern:

Be it known that I, JOHN A. KEISER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful lmprovements in Cabinet-Shaves, of which the following is a specification.

My invention relates to an improved cabinet-shave, and other similar tools.

The object of my invention is to provide ready means for removing or inserting the bit or knife, all of which will be fully set forth in the description of the accompanying drawings.

Figure 1 is a perspective view of my invention with the bit removed. Fig. 2 is a front elevation of my improvement with the bit in position for use. Fig. 3 is a bottom plan view of Fig. 2. Fig. 4: is a vertical section on line x x, Fig. 2.

A A represent the handles of my improved shave.

B represents the central portion of the stock of the shave, which, with the handles, is preferably made of malleable iron, cast in one piece. a represents ears cast on and with the stock B.

C represents the swiveling or detachable bit-face; C’, the stationary bit-face, which forms a part of the stock B.

b represents ears attached to the face C, and provided with pivots i, which hinge the ears b to the ears a.

d represents a yoke or bar connected to the ears b.

The parts C, b, b, and d are made of metal formed in one piece, and arranged so as to more freely upon the pivots i.

D represents a cam connected by pivot c to the center of the yoke d.

E represents the bit or knife, which is made to fit into the head B, as shown in Figs. 2 and 4. In order to hold the knife in position by detachable fastenings, it is essential to have it gripped at two points — first, at or near the cutting edge, and, second, at the central point of the knife, sufficiently near the upper end to prevent its rocking or moving. To accomplish this I provide lugs h, at each end of the cutter E on the bottom of face C, and adapted to bear against the cutter E upon each side of the shaving-slot L.

The mode of operation in inserting the knife is as follows: Fig. 1 represents the device with knife or bit removed from the stock of the shave and the cam D hanging loosely upon the yoke d. The knife E is inserted with the proper feed, (the edge depending below the faces C C’,) and cam D is turned upward so as to bring the shoulder against the face ofthe knife. This movement draws the lugs h, on the face C firmly against the blade E, pressing or gripping it tightly against the face C’ of the stock by the inward movement of the face C, caused by the pressure of the shoulder of cam D against the upper end of the knife, forcing the yoke d outward. This mode of constructing the stock and attaching the parts holds the knife firmly in position, and yet allows it to be instantly inserted and removed.

The principal feature of my invention consists in constructing the pivoted portion of the stock so as to grip the knife near the cutting-edge, and central at or near its upper end, and at the same time not be apt to become accidentally disconnected from its bearings.

An inferior modification of my invention would be to employ a thumb-screw passing through the yoke d, instead of the cam D, for gripping the upper end of the knife E. Such a construction would be covered by the first and second claims herein. Spokeshaves and other tools could be made in a similar manner as the within-described cabinet-shave. Another modification could be made by having the lugs h, attached to the face C’ and the shaving-slot in the same side of the bit-face. So, too, one lug h might be employed near the center of the bit-plane; but it would not be as efficient as the plan here shown.

I claim —

1. A shave composed of the stock B and bit-face C’, in combination with the bit-face C, swiveled by a pintle placed parallel with the axis of rotation of the bit-face, and a fastening device, D, suitably supported, and adapted to grip the bit at or near the top and force one of the bit-faces against the lower edge of the bit, whereby the bit will be held to its place by said fastening D and bit-face, independently of other fastenings, substantially as described.

2. The combination, with the stock B and stationary bit-face C’, of the bit-face C, provided with lugs h to bear against the bit and with yoke d, and swiveled by a pintle parallel with its axis of rotation, and a fastening device, D, connected with the yoke d and adapted to bear against the upper part of the bit, the bit being held to its place by said fastening D and the face C, independently of other fastenings, substantially as described.

3. The combination of the stock B and stationary bit-face C’, provided with ears a, the bit-face C, provided with ears b and yoke d, and swiveled to ears a by pintles i, and the cam-lever D, fulcrumed on yoke d, for instantaneonsly fastening and releasing the bit, substantially as described.

In testimony whereof I have hereunto set my hand.
