APPLICATION FILED JULY31, 1905.
UNITED sT TEs HARRY SANFORD-BURTON, OF OXFORD, ENGLAND.
GRINDING STONE AND DISK EMPLOYED IN MECHANICAL AND OPERATIVE DENTISTRY.
Specification of Letters Patent.-
Patented Feb. 20, 1906.-
Applioation filed July 31, 1905- Seiiiil No. 271,967.
To all whom it may concern:
Be it known that I, HARRY SANFORD-BUR- TON, asubject of the King of Great Britain, residing at 63 St. Giles, Oxford, En land, have invented certain new and usefuI Improvements in Grinding Stones and Disks, Especially Those Employed in Mechanical and Operative Dentistry, of which the following is a specification.
The object of my invention is to supply means for providing the disks with water or other uid automatically that the work can proceed without the oftentimes interruption due to the operator having to supply and keep supplied the grindingsurfacew1th water, t e invention being specially applicable for use with grinding disks or stones used in mechanical or operative dentistry, but is also applicable to porous and other stones or disks used for other grinding.
My invention will be clearly understood from the following description, aided by the examples shown in the accompanying drawings, in which- 1 re 1 is a sectional elevation of a watersupp y tube having a porous grind stone or disk attached. Fig. 2 is a similar view to Fig. 1, showing a water-tight acking between the reservoir-tube and t e grinding disk or stone. Fig. 3 is a similar view to Fig. 1, but showing means for su lyin Water to each side of agrind stone or dls k, eit er porous or non-porous. Fig. 4 is an elevation of a lathe-head with my reservoir-tube, axle and grinding stone or disk applied.
I attach toor makethe whole or a portion of the spindle carrying the carborundum or other grinding disk or stone A as a tube B, and connect same to the disk or stone A in the usual or other manner, preferably. by a screw O of a smaller diameter than the hole in the disk. The end of the tube B next the disk A is preferably closed except to one,'two, or more holes D, and the connection between the tube B and the disk A may be made Water-tight at the edge of the tube B in some cases b a rubber ring E, as at Fig. 2, and especia ly so when a porous stone or dlsk is used. The tube B,.I fill with water through 1grinding stones or the tube by a band G or other means, so that the water can only pass through the holes D in the end, and I have found that on the rotation of'the disk A and tube B in the usual manner the water will slowly pass from the tubular axle through or around the disk in a sufficient degree to keep the working edge or surface sufliciently moist for eiiective grindan. opening F and then seal the opening F in ing. When a non-porous stone or disk is affixed to the tube B, I place the holes D that they are open to the stone or disk outside of then connection with the tube, so that water ma be conveyed to that side of the stone, an I also slit the screw C, so that the water will pass through same and to the other side of the stone or disk, as at H, Fig. 3, whereby both sides can be supplied with water for efficient working; but such arrangement can equally .well be applied whena porous stone is employed.
In some cases, and especially for fixed machines, the tubular axle may be open to a trough or supply of water, so that it will not be necessary to refill the tube when exhausted. 7
What I claim, and desire tosecure by Letters Patent, is
1. A spindle having a hollow enlarged end forming a closed water-reservoir, and a grinding-stone secured to the outer extremity of said spindle, said reservoir provided with openings forming communications with the stone for sup lying water thereto.
2. A spin e having a hollow end forming a closed reservoir and provided with aninletport for supplyin water thereto, a grindingstone secured to t c said spindle, said hollow end provided with openings forming conduits for supplyin water to the stone, and an annular rlng s idable on the spindle for closing the inlet-port.
In testimony whereof I have hereunto set my 'hand in presence of two subscribing witnesses. I
HARRY SANFORD-BURTON. Witnesses:
RICHARD CORE GARDNER, CHARLES A. GROSSETETE.
