T0 at whom it may oonoern:

Be it known that I, CHARLES A. SPAHN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dental Tools; and I do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to i which it appertains to make and use the same, .reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention has reference to improvej ments in tools for dentists uses; and the in f vention has for its principal objects to pro- 1 vide a novel construction of tool, made in the manner of forceps, which are to be used in backing false teeth with old.

My present invention has for its principal object to provide a simply-constructed tool of the general character hereinafter more fully set forth, and which is especially adapted for quickly and easily applying gold to the I back of a tooth in an 'eflicient manner.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following de tailed description of the same.

With the various objects of this invention in view the same consists in the novel construction of dentists tool, to be hereinafter more fully set forth, for quickly, easily, and efiiciently backing false teeth with gold.

My invention consists, furthermore, in such novel arrangements and combinations of the parts of the tool, all of which will be hereinafter more fully described and then finally embodied in the clauses'of the claim, which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in whieh Figure 1 is a plan view of the dental tool embodying the principles of the present invention. Fig. 2 is a similar View of the same, the handle portions being shown partly broken away and the jaws arran ed or set for the first operation in backing false teeth with gold. Fig. 3 is a View similar to that shown in Fig. 2, except that the jaws are arranged or set to complete the operation of backing false teeth with gold. Fig. 4 is a side elevation of the novel dental tool embodying the principles of the present invention, the handle portions thereof being shown partly broken away. Fig. 5 is a detail longitudinal vertical section of the jaws of the novel dental tool set or arranged as shown in Fig. 2. Fig. 6 is a similar detail vertical longitudinal section showing the dental tool performing the first operation in backing false teeth with gold, and Fig. 7 is a similar View showing the jaws of the novel dental tool arran ed to complete the operation of backin fa se teeth with gold.

Simil ar characters of reference are employed in all of the above-described views to indicate corresponding parts. 1

In the said drawings the reference charac- 5 ter 1 indicates the complete tool, which consits, essentially, of a pair of handle portions 2 and 3, pivotally connected at 4 by means of a pin or rivet, substantially as illustrated. The handle portion 2 is provided with a forwardly and preferably downwardly extending jaw member 5, the same being of any desired and suitable configuration. The said jaw member 5 is provided at its outer or free end with a cup-like receiving-socket 6, the

5 said cup-like receiving-socket 6 being adapted to receive and hold a cap or covering 7, preferably made of rubber or a similar resilient material. The said cap or covering 7 is made slightly concave on its outer surface and is provided with a main body portion 8,

preferably in the form of a truncated cone adapted to be inserted in the said cup-like receiving-socket 6, and the said cap or covering 7 is further provided with an an'nularlyextending rim or bead 9, adapted to engage the outer edges of the said cup-like receivingsocket, substantially as illustrated, and the whole providing a suitable supporting mernber or cushion, as will beclearly evident more particularly from an inspection of Figs. 6 and 7 of the drawings.

The handle portion 3 is provided with a forwardly-extending arm 10, provided at its outer or free end witha slot or opening 11, within which is pivotally connected, by means of a pin or rivet 12, the tongue 13 of a forked jaw member 14. The said forked jaw member 14 is provided with a pair of downwardly-extending arms 15 and 16, the said arm 15 being provided upon its outer or free end with a cup-like receiving-socket 17, the said cup-like receiving-socket 17 being adapted to receive and hold a cap or covering 18, preferably made of rubber or a similar resilient material. The said cap or cover ing 18 is made slightly convex on its outer surface and is provided with a main body portion 19, preferably in the form of a truncated cone, adapted to be inserted in the said cup-like receivin -socket 17, and the said cap or covering 18 is rther provided with an annularly-extending rim or bead 20, adapted to engage the outer edges of the said cup-like receiving-socket 17, substantially as illustrated, and these parts providing a suitable presser or conforming member or cushion. The said arm 16 of the said forked jaw member 14 is provided on its outer or free end with a downwardly-extending pressure-exerting member 21, provided at its end with a small hole or opening 22.

The manner of using the tool for backing false teeth with gold is as follows: In Fig. 6 I have represented a tooth 23, provided with the usual studs or pins 24 for securing the same to a bridge or the like. The said tooth 23 is placed upon the concave surface of the cap or covering 7 of the jaw member 5, and the arm 15 of the forked jaw member 14 is turned so as to form the opposing jaw and provide a forceps-like tool. The cap or covering 18 of the arm 15 is then opposite the cap or covering 7 of the jaw member, 5. A sheet or piece of gold is then laid over the back of the tooth and the two caps or coverin s 7 and 18 are pressed together with the said tooth between them. The action of the rubber caps or coverings 7 and 18 serves both to hold the tooth in place and at the same time by equalizing the pressure over the surface of the tooth adapts the gold thereto, forcing the gold into all the uneven places in the conformation of the tooth. To complete the operation, the downwardly extending member 21 is turned into its operative position to form the opposing jaw of the forcepslike tool and the hole or opening 22 therein is placed over the pin or stud 24 of the tooth, and the pressure which is then exerted serves to adapt or press the gold around the base of the pin or stud 24. The false teeth are usually provided with two of such pins or studs 24, and the punch member 21 is so constructed that it will readily pass between them while in operation.

From the above description it is clearly evident that I have provided a simple and inexpensive tool which can be easily and quickly manipulated to efficiently back false peettlli With gold, for the purpose above set ort I claim- 1. A dental tool for backing false teeth with gold, comprising a pair of pivoted handle portions, a forwardlyextending jaw member-provided at its free end with a resilient cap or covering connected with one of said handle portions, and a forwardly-extending arm connected to the other handle portion, said forwardly-extending arm being rovided with an oscillating forked j aw memher, one of the arms of the said forked jaw member being provided at its free end with a resilient cap or covering and the other arm of the forked jaw member being provided at its free end with a pressure-exerting member, substantially as and for the purposes set forth.
