CLARENCE PETER STANBROUGH, OF NEVBURGH, NEW YORK.

VETERINARY TOOTH=CUTTER.

`l..'in'iTGN forming part of Letters Patent No. 670,086, dated March 19, 1901.

Application filed June 26, 1900. Serial No. 21,611. (No model.)

To all 'LU/tom t may concern:

Be it known that. I, CLARENCE PETER STAN- BROUGH, a citizen of the United States, and a resident of Newburglncountyof Orange,and State of New York, (post-office address, Newburg, New York, Box 87,) have invented certain new and useful Improvementsin Equine- Tooth-Outting Apparatus, of which the followingis a specification, reference being` had to the accompanying drawings, forming a part thereof', in which similar letters of referlence indicate corerspondiug parts.

This invention relates I0 an improved equine-tooth-cutting apparatus; and the object thereof is to provide a device of this character which is readily adapted for operation upon the molar or back as well as the front teeth of a horse.

The deviceis simple in construction, durable, and inexpensive, and it can be operated by any common form of motor.

The invention will be hereinafterfully described, and specifically set forth in the annexed claims.

In the accompanying drawings, forming part of this specification, Figure l is a side elevation of an improved cutter, partly in section: and Fig. 2 is an edge elevation.

ln the practice of my invention I employ, primarily, a metallic guard A, embodying the rear wall n, the side walls d', the journal-box a2, and the end wallets. Withiuthis guard revolve the cutters B, which preferably comprises a plurality of disks composed of any suitable material having a rougheued peripheral surface. The cutters B are mounted upon the end of a shaft C, which is journaled through the box d2, and said cutters are retained in place by means of a nut c, which is threaded to the end of the shaft C. This said shaft C extends downwardly through a metallic tube D and connects with a flexible shaft 0, which has connection with a squared rod C2, adapted to be coupled to a suitable motor for operating the cutters. The flexible shaft C is covered by a exible tube D', which is provided at its upper end with a metallic collar d for engagement with the tube D and at its lower end with a metallic collar CZ, adapted to act as a journal-box for the driving-rod C2.

Extended from the rear wall et of the guard A are two lugs A4, and pivoted between these said lugs by means ofthe pin e is the handle E, which is adapted to swing freely upon the said pivot. This handle embodies the screw E@ the tubular coupling F, which abnts against the lower surface of the lugs a4 or against the angular shoulders a5 thereof, as desired, the extension-rod G, the tube H, and the wooden hand-grip I. The screw E/ threads into a socketf of the coupling F, anda similar screw E2 ispivoted between the jaws f of the coupling F and threaded into a socket g in the headg/ of the rod G. The couplingF is further provided with angular' shouldersjl2 and f3 for contact with the upper end of the rod-head g to maintain the rod Gin position at an angle with the coupling F.

The tube H, which surrounds the rod Gr, is provided with a longitudinal slot h, which engages a pin g2, extended from the said rod. This pin limits the sliding ,movement of the tube on the rod to keep them from becoming detached from each other.

As a means for locking the tube H in desired position on the rod G, I provide a thumbscrew J, which threads through a tubular extensionh' of the tube H and contacts at its inner end with the rod G.

In the operation and use of the device rapid rotary motion is imparted to the cutters through the medium of the flexible shaft C and any suitable motor. The operator then places the handle Ein desired relative arrangement with the guard A, eitherat an angle to or parallel therewith, by adjusting the screws E and E2 in their respective sockets, which permits of the handle being extended at angle as illustrated by dotted lines l, Fig. l of the drawings, or at either of the angles as shown by dotted lines 3 and 4, Fig. 2 of the drawings, thus providing a device which can be variously employed for bringing the cutters into Contact with any tooth of the horses head--mOIa-r, front, top, and bottom.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

l. Asacutting device for horses teeth the combination with a rotary cutter and means for operating the same, of a guard having lugs extended therefrom with angular shoulders and a swinging handle pivoted between IOO said lugs and adapted to alternately engage the surface of the lugs and the angular shoulders thereof, substantially as shown and described.

2. As a cutting,r device for veterinary use the combination with a rotary cutter embodying` a plurality of disks, a shaft retaining said disks and a flexible shaft for rotatingr them, of a guard having lugs thereon with angular shoulders, and a swinging handle comprising a coupling having jaws with angular shoulders, a screw threaded in a socket of said coupling and pivoted between the said lugs, a screw pivoted within the jaws of the said coupling and a rod provided with a threaded socket and engaging said screw, whereby the handle may be maintained at Varyingr angles relative to the said guard, substantially as Shown and described.

3. As a cutting' device for veterinary use,

the combination with a rotary cutter and means for rotating the sam e, of aguard having lugs with angular shoulders, a swinging handle comprising a telescopic rod adapted for extension, a coupling having angular shoulders, and screws connecting said coupling respectively to the telescopic rod and the said lugs of the guard, whereby the handle may be maintained at varying' angles relative to the guard and its cutters, substantially as i shown and descri bed.

In testimony that I claim the foregoing as myuvention I have signed my naine, iu presence of two witnesses, this 15th day of June, 1900.

CLARENCE PETER S'IANBROUGI.
