Description
H. A. LANGE. GRAVER SHARPENER.
APPLICATION EILED JAN-15. I917- Patented Sept. 11, 1917.

GRAVER-SHARPENEB.
manner.
Application filed January 15, 1917.
To all whom 2'25 may concern:
Be it known that I, HUGO A. Larson, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in. Graver- Sharpeners, of which the following is a specification.
This invention relates to a tool for sharpening gravers, and is especially intended for the purpose of enabling an engraver or his assistant to sharpen a number of gravers exactly alike, sometimes very difficult if not in section.
Fig. 3 is an enlarged sectional view, the tool being in side elevation and the parts constituting my invention being in a slightly different position from that shown in Fig. 1.
Fig. a is a detail perspective view of a split block.
Fig. 5 is a detail perspective view of a plug.
In the drawing A represents the tool handle and B the tool. These form no part of the invention, and the invention is not limited in its use to this one particular kind of tool, which is shown only for the purposes of illustration and in order to more clearly bring out the use of the device.
My invention consists of a sleeve 1 having a shghtly reduced portion 2 and a boss 3. Working through the boss is a binding screw 4. The inner end of this screw is recessed shown at 5 and in said recess is loosely mounted a cylindrical plug 6. Said plug carries a notched binding member or head 7, as most clearly shown in Fig. 5. Arranged within the sleeve in any desired manner is a cooperating notched block 8 which rests opposite to and faces the transversely movable head 7 of the plug 6. The tool B is passed through the sleeve 1 and the sleeve is then clamped upon the tool by Specification of Letters Patent.

Serial No. 142,519.
tightening the screw 4: forcing the head 6 of the plug into engagement with the tool, clamping the tool between the head 7 and the block 8. The screw of course rotates with respect to the plug 6.
At its forward end the sleeve carries a yoke 9 which yoke at one end is provided with a roller 10 extending substantially the width-of the yoke. At the other end it is provided with side brackets 11 in which are mounted rollers 12, and as shown in Figs. 1 and 3 either set of rollers may be brought into use, the yoke being rotatable on the sleeve, said yoke carrying between its side members a split block 13 which is rotatable about the reduced portion 2 of the sleeve 1. The block 13 is held in the yoke and is also clamped to the sleeve by means of a binding screw 14, the yoke being slotted longitudinally along one member as shown at 16, and the screw 1 lpassing through said slot and through the split portion of the block. The block is suitably flanged as shown at 15 so that it is held within the yoke, and at the same time permitted to have a sliding movement therein. Suitable degree marks are placed upon the front face of the block 13 and a suitable scale is placed upon one member of the yoke 9.
The bore of the sleeve is not cylindrical but is rather triangular in cross section, thereby afiording a better bearing surface for the tool, as shown in Fig. 2.
In operation the graver is fastened to the device by the screw 4 and the swivel plug 6, about one and a half inches of the tool projecting beyond the sleeve. The slidable block 13 is then adjusted in the yoke the desired height, and the sleeve rotated with respect to the block, or the yoke and block with respect to the sleeve, until a suitable mark upon the sleeve, indicated at w registers with one of the forty-five degree marks on the block.. It is then clamped by the screw 14, and the device is then run back and forth upon the stone, traveling on the rollers 12. It is then adjusted to the other forty five degree mark, and the operation repeated. Both of the lower sides of the tool must be beveled so that the point is directly in the center of the graver. After the lower sides are finished, the sleeve is turned to bring the mark at .to the highest point, or the one of ninety degrees. It is then tightened and the tool inverted, but the sliding adjustment of the block is not disturbed, and the top of the tool ground, the device traveling on the roller 10. This will give a perfect cutting angle of forty five degrees, and perfectly flat, and the lower sides only are then polished with 4:0 emery paper.
time to complete the entire operation.
WVhat I claim is:
1. A device of the kind described com prising a sleeve, means for clamping said sleeve to a tool to be sharpened, a block rotatably mounted on said sleeve, a yoke adjustably connected to said block, and rollers carried by said yoke and adapted to support the yoke, sleeve and tool. e
2. The combination with a tool, a sleeve adapted to fit thereon, means for clamping to the tool, a split block rotatably mounted This completes the sharpening of the tool and 1t requlres about one minutes' upon said sleeve, and a yoke mounted upon said block, the block being slidable between the yoke members, and suitable graduation marks carried by the sleeve, block and yoke respectively.
3. A graver sharpener consisting of a sleeve adapted to receive the graver, a screw working transversely in the sleeve, a plug fitting loosely in the inner end of the screw and projecting therefrom and adapted to engage said graver, a split block rotatably mounted on said sleeve, ,a yoke adjustably mounted on said block,,:rollers carried by the ends respectively of the yoke, and ,a binding screw working through said yoke and block. 7
