V CABINET SHAVE. N0.'300,Z66.' Patented June 10, 1884.
UNITED STATES PATENT (Enrica.
JOHN A. KEISER, or CINCINNATI, OHIO, ASSIGNOR TO SAMUEL o. TATUM & 00., or SAME PLACE.
CABINET-SHAVE.
SPECIFICATION aimin part of Letters Patent No. 300,266, dated June 10, 1884.
Application filed February 28, 1884. (No model.)
To all whmn it new concern:
Be it known that I, JOHN A. KEISER, a citi zen of the United States, and a resident of Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements 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 wilt be fully set forth in the description of the accompanying drawings.
Figure l 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 a .r, 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 13.
C represents the swiveling or detachable bit-face; G, the stationary bit-face, which forms a part of the stock B.
'0 represents ears attached to the face 0, and provided with. pivots 2', which hinge the ears I) to the ears 0.
(1 represents ayoke or bar connected to the ears I).
The parts C, I), I), and d are made of metal formed in one piece, and arranged so as to move freely upon the pivots i.
1) represents a cam connected by pivot c to the center of the yoke (Z.
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 pointsfirst, 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 0, and adapted to bear against the cutter E upon each side of 0 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 l) hanging loosely upon the yoke d. The knife E is inserted with the proper feed, (the edge depending below the faces 0 O,) and cam D is turned up= ward so as to bring the shoulder against the face of the knife. This movement draws the lugs h on the face 0 firmly against the blade E, pressing or gripping it tightly against the face 0 of the stock by the inward movement of the face 0, caused by the pressure of the shoulder of cam D against the upper end of the knife, forcing the yoke (l 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 cuttingedgc, and central at or near its upper end, and at the same time not be apt to become acci- 7 dcntally disconnected from its bearings.
An inferior modification of my invention would be to employ a thumb-screw passing through the yoke (Z, 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. Spokcshaves and other tools could be made in a similar manner as the within-described cabinet'shave. Another modification could be made by having 85 thclugs it attached to the face (3 and the shaving-slot in the same side of the bit-face. So, too, one lug it might be employed near the center of the bit-plane; but it would not be as efficient as the plan here shown. 90
I claim 1. A shave composed of the stock B and bit-face O, 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 adapt ed 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'I) and bit-face, independently of other fastenings, substantially 8. The combination of the stock B and sta 15 tionary bit-face 0, provided with ears (1, the bit-face 0, provided with ears b and yoke d, and swiveled to ears a by pintles i, and the cam-lever D, fulcrulned 0n yoke d, for instantaneously fastening and releasing the bit, substantially as described.
In testimony whereof I have hereunto set my hand.-
JOHN A. KEISER.
