DENTAL-'INSTRUMENT SHARPENER.
The object of my invention is to providemeans for supporting a dental tool on an oil stone and insure the accurate and 1uniform sharpening of the point ofthe tool and an even beveling4 of its cutting face.
The invention consists generally in an arm, having a foot piece or base at one end and a clamping member at the other end provided with a single clamping screw, by
means of which a dental 4tool can be held and locked at any desired angle with respect to the surface of the stone.
In the accompanying drawings, forming part of this specification, Figure 1 is a perspective View, illustrating my tool in use, Fig. 2 is a top view of the tool, Fig. 3 is a side view, Fig. 4 is a detail, sectional view, illustrating the construction of the clamping mechanism. y
In the drawing, 2 represents a table, 3 an oil stone, 4 a metallic arm having a base or foot piece 5 that is adapted to restand slide upon the table. This arm is ofv suitable length and is provided on its outer end with a split collar 6 that is held in place on the arm by a washer 7 and a rin 8, the collar being ca able of oscillating 'reely between said was ier and ring. A pin 9 is fitted within a socket in the collar and has one end provided with a head 10 having a-hole 10 therethrough, in which the shank of the dental tool is inserted. A disk 11 is provided on the pin 9 and has a socket 12 to receive the head 10-the pin having a squared portion 14 at the point where `it passesthrough the disk to prevent rotation of the disk on the pin. Thedisk is also preferably provided with a hub 15, fitting within a correspondingly shaped socket in the collar. Onthe opposite side of the collar the pin is threaded and provided with a thumb nut 16, having a sleeve 17 on one side inclosing a spring 18 that is adapted to bear on the split collar and draw the head 10 into the socket 12 and hold the shank of the tool 'a ainst the disk with a yielding pressure. on releasing thisthumb nut, the tool can e revolved with the pin as an axis 'and at the same time. the collar will Specification of Letters Patent.

be loosened on the arm 4 and the tool and pin. may be oscillated with the collar on the arm 4 as an axis. I am thus able to adjust the tool in vertical planes at right angles to one another and set 1t at any desired inclination to the surface of the oil stone.
IV ith this device, a dental tool of any shape can be` supported on an oil stone and a uniform bevel obtained on the cutting edge and whenever it is desired to re-adjust the tool or remove it from its support, it is onl necessary to manipulate a single thumb screw. 'l
The ring 8 and the disk 1l have graduations 19 and 2O thereon opposite marks A. and B. on the collar and by means of these graduations, the. operator of the tool can adjust the clamp to obtain the right inclina'- tion for the bevelon the tool. Then the shank of the tool can be marked to correspend to the adjustment of the graduations and -when the tool is sharpened again, it will only be necessary to set the graduations asindicated by the marks on the tool. shank and be sure that the proper inclination is obtained for the bevelon the tool point. The disk 1l is provided with a Bange 11 that is adapted to enter the notch 1n the shank of the tool and enable the operator to easily and quickly set the tool in the clamp.
Considerable time would be required in adjusting the clamp device to Iit the bevel on the tool to the surface of the stone, but with my device, when this adjustment has once been obtained and the shank of the tool marked, it will be a very simple matter to again mount the same vtool in the clamp so that its bevel will bear evenly on the stone surface.
I claim as my invention:
1. A device of the class described comprisign an arm having a base or foot at one end adapted to rest upon a table and freely .movable thereon and a clamp mounted on the op posite end ot' said arm, said clamp having a socket to receive a dental tool shank, said shank having a revolving movement inde pendently of said clamp and a movement with said clamp at an angle to said arm, substantially as described.
2. A device of the class described, compris- 'ing an arm having a base or footat one end p i be swung. in a plane parallel with said arm orat an angle thereto, and a single clampin screw adapted to lock said clamp on said arm andthe shank of the tool on said clamp simultaneously. A
3. A device of the class described, comprising an arm having a base or foot piece at one end adapted to rest on ya table or other surface, a clamp mounted on the opposite end of said arm and comprising a split :collar adapted to oscillate at right angles to said arm, a screw passing through said collar and having a head at one end provided with a socketJ to receive the shank of a dental tool,
the opposite end of said screw being threaded and provided with a thumb nut and the movement of said nut serving to tighten said collar on said arm and look the tool shank in its socket, substantially as` described. l
4. The combination, with a supporting arm, of a clamping device'm unted thereon andy comprising a split collar? a screw passing therethrough and having a head on one end and provided With a socket to receive4 the shank of a tool, a disk interposed between said head and collar and adapted to bear on the tool shank and having a graduated periphery, and a ring secured on said arm also having la graduated surface and said collar having marks opposite Said graduated surfaces, and said screw having a threaded end and a thumb nut therefor adapted to contact with said collar, substantially as described.
5. The combination, with a supporting arm, having a graduated ring secure thereon, of a s ht collar loosely mounted on said arm and iaving a mark opposite the graduations on said ring, a pin passin through said collar and having a threade end provided with a thumb nut, and ay head having a socket to receive the shank of a dental tool, and a spring arranged on said screw between said thumb nut and collar, substantially as described.
6. A devicel of the class described, couiprising an arm having a foot or rest at one end, 'and a clamping device mounted on its opposite cud, said clamping device having a socket to receive the shank of a dental tool, and a'single screw and a thumb nut therefor, arranged to lock said clamping device on lsaid arm and simultaneously secure the shank of the tool in said socket, substantialhv as described. i
In Witness whereof, I have hereunto set myhand this 2nd da of Januar 1909.
