mm M wire STATES CLINTON \V. MILLER, OF CHICAGO, ILLINOIS.

DENTAL'TOOL.

SPECIFICATION forming part of Letters Patent N 0. 644,932, dated March 6, 1900. Application filed July 20,1899. Serial No. 724,539. (No model.)

To all whom it may concern:

Beit known that I, CLINTON W. MILLER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dental Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to dental tools, and particularly to that class designed for use in shaping metals.

The object of the invention is to provide novel means whereby tooth-crowns, of metal, may be bent, expanded, or otherwise altered that the proper contour or configuration of the natural crown may be imparted to the artificial crown to insure contact throughout the usual contiguous surfaces of the said natural and artificial crowns.

Furthermore, the object of the invention is to provide a device which will prove simple, eflicient, and comparatively inexpensive.

With the above and other objects in view the invention consists in the detail of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing'the invention in detail reference will be had to the accompanying drawings, forming part of the specification, wherein like characters refer to corresponding parts in the several views, and in which- Figure 1 is a perspective view of a dental tool embodying the invention. Figs. 2 and 3 are detail views showing rollers having faces of varying contours and also the relative sizes and position of the parts.

In the drawings, 1 1 indicate the two members of the ordinary pliers joined by the pivot 2. The noses 3 3 of themembers are preferably round in cross-section, and the end of one is reduced to produce a spindle 4, while the other is truncated and provided with a socket A. The spindle 5 is removably fitted in the socket, and the set-screw A of any ordinary construction is supplied for retaining said spindle in place. Rollers 6 and 7 are mounted on the spindles, and the faces thereof engage the metal or crown operated upon. The faces of the rollers may be plain,

with the outer edges rounded, or one may be convexed and the other concaved, as illustrated in Fig. 2, or both may be convexed, as shown in Fig. 3. In operation the bicuspidcrown would best be produced by the use of the concaved wheel a, as shown in Fig. 2, and a molar-crown could be formed with a convexed wheel, as shown in Fig. 3. It will of course be apparent that the wheel may be of various other shapes to produce the results sought by the individual operator.

The spindle A has a head A and theroller 7 thereof is recessed at the end that the head may fit almost flush with the end of the roller to produce a neat appearance and prevent the head of the spindle from contacting with the crown.

The end of the spindle 4 is upset to hold the roller in place; but instead of its being upset means (not shown) may be provided whereby this roller could also be made removable, as it is mypurpose to have them interchangeable that a set of rollers designed for different results might be employed with one pair of pliers.

The spindle 4 is usually shorter than the spindle 5, and the roller 6 is shorter than the roller 7. The roller 6 is also of less diameter than the roller 7. When thus arranged, the smaller roller lies within the crown against the inner surface, and th'e'larger roller engages the outer surface. As the larger roller is also longer than the smaller one, the said larger roller will extend above the grindingsurface of the crown to prevent the formation of a crease or ridge. If desired, the rollers may be made sufficiently small to pass within the crown for expanding or otherwise operating on the metal.

The construction and advantages will, it is thought, he understood from the foregoing description, it being understood that changes in the proportions or shape of the rollers, spindles, or pliers may be made without departing from the scope of the invention and claims.

Having fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A dental tool comprising two members pivoted together, each member having a roller with its axis longitudinally disposed with relation to said member.

2. In a dental tool, two members pivoted together to produce handles, with extensions beyond the pivot; one of which is reduced to form a spindle, a removable spindle attached to the other nose and rollers on the spindles.

3. In a dental tool, two members pivoted together to produce handles, extensions beyond the pivot, spindles carried by the extensions; one of said spindles being longer than the other, and rollers of varying dimensions and shapes mounted on the spindles.

4:. In a dental tool, two members acting in conjunction, and a fixed and removable roller carried by the members.

In testimony whereof I affix my signature in the presence of two witnesses.

CLINTON W. MILLER. Witnesses:
