UNITED STATES PATENT OFFIC WILLIAM CURTIS DEANE, OF NEW YORK, N. Y.
DENTAL TOOL.
SPECIFICATION forming part of Letters Patent No. 391,302, dated October 16,1888.
Application filed August 23, 1888. Serial No. 283,558. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM CURTIS DEANE, of the city, county, and State of New York, have invented a new and useful Improvementin Tootl1-Grown-Trimming Wheels; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure l is a side elevation of my improved tooth-trimming wheel, and of a Logan toothcrown to be operated upon; Fig. 2, a central diametric section of the wheel and its spindle, illustrating its application and use in grinding the toothcrown; Fig. 3, a similar sectional view showing a modification in the form of the face of the wheel.
The object of my invention is to facilitate the grinding of a toothcrown having a central pin or post without risk of damaging the post to adapt the crown for mounting upon an appropriate root.
It consists in the combination of a suitable facing-wheel with a rotating mandrel or spindle having a central axial recess in the outer end thereof large and deep enough to permit of the free insertion therein of the post of the tooth, so as to permit the outer face of the wheel to bear upon the end of the crown concentrically about the post without contact with the post.
In the accompanyingdrawings, A represents a Logan or Brown tooth-crown, and Bits platinum .post.
0 represents a corundum-wheel adapted to grind the upper end of the crown, and D the rotating spindle or mandrel to the end of which said wheel is secured. This spindle D is enlarged at its outer end, which is formed with a suit-able bearing, e, to fit accurately within the central perforation in the wheel, and with an annular offset, f, forming a shoulder against which the wheel is supported when forced in upon said hearing, as shown in Fig. 2. A cen tral recess, G, is formed axially in the outer end of the spindle of such depth and diameter as to admit of the free insertion therein of the post B of the tooth A and permit of the application of the outer face of the wheel to the upper face of the crown encircling the post without contact with the post, as shown in Fig. 2. The diameter of the recess G so far exceeds that of the post B as that the post may be inclined more or less within the recess without contact with its sides, so as to permit the crown to be inclined more or less to the face of the wheel, if required.
The face of the wheel to be applied to the crown may be flat, as shown in Figs. 1 and 2, or be centrally convex, as shown in Fig. 3, so as to project more or less for the purpose of grinding out a concentric recess in the face of the crown around the base of the post.
The spindle or mandrel D is adapted to be attached in the customary manner to the flexible shaft of a dental engine, or to any suitable form of lathe, so that it may be rapidly rotated when in use.
I claim as my invention-- 1. The combination, in a tooth-crown trimmer, of the axially-recessed spindle and the encircling facing-wheel fitted thereon, substantially in the manner and for the purpose herein set forth.
2. The toothcrown trimmer consisting of a central spindle formed with an axial recess at its outer end, a bearing encircling said recess, and an annular shoulder encircling the inner end of said bearing, in combination with a grinding-wheel fitted upon said bearing to rotate with the spindle, substantially in the manner and for the purpose herein set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WILLIAM OURTIS DEANE.
