L. A. YOUNG DENTAL POLISHING CUP AND OTHER POINT Filed Dec. 19, 0
WNW two Patented Dec. 22, 1931 UNITED STATES LUTHER ALVIN YOUNG, OF ORLANDO, FLORIDA DENTAL POLISHING GUI OTHER POINT I Application filed December 19, 1930. Serial No. 503,547.
The invention relates to improvements in cups and other points adapted for rotation by means of driven arbors and designed primarily for use by dentists for polishing purposes.
It is the object of the invention to provide a new and improved construction permitting one cup or point to be quickly and easily removed from the arbor and another one applied with equal ease, whenever desired, novel provision being made for tenaciously connecting the cup or point with the arbor, yet for permitting easy disconnection thereof.
With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.
Fig. 1 is a verticalsectional view partly in elevation showing one form of construction.
Fig. 2 is a transverse sectional view on line 2-2 of Fig. 1.
Fig. 3 is a perspective view of the driving member shown embedded in the cup or point, in Fig. 1. V Fig. 4 is a plan view of the blank from which the driving member of Figs. 1 and 3 is formed.
Fig. 4 is a fragmentary elevation, showing a variation over Fig. 4.
Fig. 5 is a side elevation partly in section showing the relation of the cup or point with the usual angular terminal on the flexible shaft of a dental engine or the like.
The device is shown in the form of a cup, but may be of other shape, corresponding to any of the points now used. It is formed. from rubber or other suitable material and terminates at its rear portion, in a body 11 having a socket 12 which is closed at its front end, open at its rear end, and pro vided with a non-circular cross-sectional shape, the socket being preferably four-sided as seen most clearly in Fig. 2, with its side walls substantially flat. The rear extremity of the body 11 is preferably formed with a recess 13, around which is a flexible flange 1 1 to abut the usual handle or other terminal on the end of the flexible shaft of a dental engine or the like as seen in Fig. 5, preventing any grit and the like from finding its way into the shaft bearings. The interior diameter of the flange 14 is greater than the diameter of the arbor or mandrel with which the cup or point is used, to accommodate the projecting end 14: of the usual hollow spindle of the shaft terminal.
In the form of construction shown in Fig. 1, a driving plate 15 is embedded in the rear portion of the body 11 and is formed with a non-circular opening 16 whose edges are exposed at the sides of the sockets 12, said plate being provided with a plurality of forwardly projecting arms 17 which are also embedded in the body 11. The structure 15-1617 is preferably bent from a single metal blank such as that shown in Fig. 4. This blank may be varied in form, for instance by widening the ends 17 of its arms 17.
The mandrel or arbor 18 for use with the cup or point having the embedded driving plate 15, is provided at its front end with a non-circular coupling member 19 shaped for reception in the opening 16 and the socket 12, said member 19 and an adjacent portion of the mandrel or arbor 18 being longitudinally split as at 20 to render them radially yieldable. The member 19 is provided with a peripheral groove 21 adapted to be held in engagement with the edges of the opening 16, under the resiliency of said member, as seen in Fig. 1, thereby tenaciously connecting the cup or point with the mandrel or arbor. 8
Whenever, the cup or point is to be removed however, it is simply necessary to pull it in the proper direction. Similarly, to apply this cup or point or another, it is only neces sary to force it onto the coupling member 19.
Hence, quick and easy changing of cups or points may be effected.
While the details disclosed may Well be followed, attention is invited to the fact that Within the scope of the invention as claimed, minor variations may be made.
I claim I y Y A dental polishing device comprising a body Whose rear portion is formed With a central socket, said socket having an open rear end and a closedfront end and being of non-circular cross section, and a plate embedded in said bodyand havingintegral-arms projecting forwardly and also embedded in said body, said plate havingia non-circular, opening Whose edges are exposed at the side Wall of the socket for yielding engagement With a mandrel-carried coupling member.
In testimony whereof I aflixrmysignatnre.
