IPATE'NTED APR. 2, 190v.
IINVENTOR ATTZRNE Y WITNESSES THE NORRIS PETERS cc., wAs m croN. 04 c murnn STATES PATENT rron.
Specification of Letters Patent.
Patented April 2, 1907.
Application filed November 1,1906. Serial No. 341,583.
To all whom, it may concern.-
Be it known that I, WILLIAM G. WILsoN, a citizen of the United States, residing at Wheatland, in the county of Yuba and State of California, have invented new and useful Improvements in Shears-Sharpeners, of which the following is a specification.
My invention relates to a device for sharpl holding with the fin emng shears, scissors, and like tools having beveled cutting edges.
It consists in the combination of holder and sharpening-tool and associated parts and in details of construction, which will be more fully explained by reference to the accompanying drawings, in which igure 1 is a perspective view of the device. Fig. 2 is a vertical section. Fig. 8 is a detail of the stop-hook, and Fig. 4 a detail of the clamp-spring.
In sharpening tools having beveled cutting edges, and especially shears such as are used by barbers for hair-cutting, it is necessary to have the shear-blade held with its beveled edge accurately in the plane of movement of the grinding or sharpening tool, and it is also desirable to hold such tool so that its line of movement will be diagonally across the edge to be sharpened, so that the micro scopic roughened edges produced by the tool will stand at such an angle with relation to the cutting movement of the shears that the hair will be held so as to be cut instead of being pushed away or caused to slide along the edges of the blades, as would be the case if the incline of the grinding was'in the opposite direction.
In the drawings I have shown a base A, having a front portion A inclined with relation to the bottom portion A, so that the flat surface of the shear-blade 2 may rest upon this inclined surface with the beveled edge of the blade 3 presented upwardly.
4 are nuts turnable upon screw-threaded shanks 5, which extend through slots 6 in the inclined front A, and these screw-threaded shanks have heads 7 interior to or behind the front A, which limit the outward movement of the bolts. These bolts are normally pressed outward by springs 8, located behind the inclined front A, and they may be set at any desired point, so that the shearblade being laid upon this inclined front and its rear portion resting against the blades the beveled edge 3 will be presented just above the upper edge of the inclined front A.
9 are spring or equivalent stops located near the ends'of the upper edge of the front A and so formed that the beveled edge 3 of the shear-blade will contact with these stops when the springs 8 have moved the holdingnuts 4 and the shear-blade up to the proper position. The blades may then be secured either by screwing the nuts 4 down tight by gers, or by means of a clamping-spring 11, so that the beveled edge of the blade will be held in the proper position.
12 are standards or supports extending upward from the base portion A, and between these supports extends a rod 13, which is substantially parallel with the edge of the shear-blade when the latter is in position.
The grinding or abrading surface 14 may consist of any suitable sharpening-stone fixed upon a holder or carrier having a handle 15, and this carrier has a-guiderod 16 fixed to its back.
17 is a link so formed as to inclose the guide-rod 16 and the transverse rod 13 and to thus hold the sharpening-tool 14 at an inclination diagonally to the edge of the shearblade.
The operation would then be as follows: The blade being fixed as previously described, the sharpening-stone 14 is allowed to rest upon the edge of the blade, and the position of the rod 13 will hold the stone in the plane of the bevel of the shear-blade. The stone may then be reci rocated by taking hold of the handle 15, t e guide 16 and the link 17 insuring its movement in the plane of the beveled edge of the blade, and at the same time the movement will be diagonal with it, so that all the fine roughnesses formed upon the edge of any sharpened blade will be diagonally across the blade and will thus insure its catching and holding the hair to be cut. It will be understood that after the blade has been set the stops 9 may, if desired, be turned backwardly out of the way, so as to allow the sharpening or grinding device to be moved the full length of the shear-blade, the latter being held in place by the spring 11, or it may be held by the fingers, if desired.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. In a device for sharpening tools having beveled edges, an inclined support for the tool, means by which the beveled edge is held with relation to the support, a guide- IIO reciprocated transversely bar standing parallel with the tool edge, a sharpening-tool having a longitudinallyfiXed rod upon the back, links loosely connecting said rod with the first-named guidebar whereby the sharpening device may be of the blade, and is also slidable from end to end of the guide- 2. In a device for sharpening beveled-edge tools, an inclined surface upon which the tool may rest, said surface having transverse slots made in it, spring-pressed bolts extending through the slots having heads adjustable upon the outer ends and forming supports for the blade, stops against which the edge of the blade contacts, a reciprocating guided sharpening device, and mechanism whereby said device may be moved transversely across the edge of the tool, and longitudinally from end to end thereof.
3. In a sharpening device for beveled-edge tools a base having an inclined slotted face,
spring-pressed adjustable clamps carried upon said inclined face and adapted to support the back of the tool, stops against which the cutting edge of the tool abuts and by which its position is adjusted, a bar supported arallel with the beveled edge of the tool, a s arpening device having a guide u on its back, links connecting the guide and t e bar, said links being so disposed as to maintain the sharpening device in the plane of the edge to be sharpened and diagonal thereto, said sharpening device being also movable from end to end of the supporting-bar and the tool edge.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
WILLIAM G. WILSON.
