Specification of Letters Patent.

Patented Jan. '7, 1908.

Application filed March 19. 1907. Serial No. 863,221.

T 0 all whom it may concern:

Be it known that I, HARRY A. GoLLoniN, 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 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention is designed to provide pliers or a 'combinatioi'i tool for a dentists use, which is to be operated when a tooth is to be attached to the crown of another tooth, and where it is necessary to solder the artificial tooth to the back of the adjoining tooth or teeth, in the mouth of the person.

The invention is designed to provide a tool that will fasten, to the artificial tooth, a gold backing which is commonly used, and to pass through the backing to perforate it to allow the backing to be set over a pair of pins, which project from the artificial tooth; to distort or upset these pins to cause the backing to lie flat and tight against the tooth; to provide a means for cutting off these pins after they have been upset, and to thus furnish an instrument that will take up all the steps necessary in the class of work mentioned herein.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a side view of the combination tool, and Fig. 2 is a top view of the same on an enlarged scale. Fig. 3 is a view of the artificial tooth to be attached, and Fig. 4 is a perspective view of the backing, this backing being exaggerated in thickness in the drawings. Figs. 5 to 9 inclusive, are views illustrating the steps in which this tool is employed.

1 form the pliers of any usual handle portions 10 which are pivoted at 11, and have the two projecting jaws 12 which are made somewhat elongated so as to allow a good view of the work being done. These jaws 12 provide a space 18 between them, and on the ends where they clamp together they are provided with the recesses 14, the purposes of which will be described. hereinafter. Secured to one side of one of the jaws 12 is a plate 14 which has the projecting arms 15,

each arm having a perforation 16, these perforations being of different sizes, according to the pin inuse on the tooth on which the work is to be done. The plate 14 has a projecting edge 17 which has a recessed portion 18, and a lip 12) having a perforation 20 therein.

Attached to one of the jaws 12, and projecting therefrom, is a stud 21 which has on its end a pin 22. When the tool is to be operated, a tooth 23 which is to be secured in a patient's mouth, is provided with pins 24, these pins being common as now used in the dentists art, and these pins are made of platinum. in conjunction withthis toothis used a plate or backing 25 which goes next to the. tooth.

The first step is illustrated in Fig. 5, where the backing is taken and placed on a rubber or other resilient block 26, and the pin is used. to perforate the backing with holes spaced so that they will go over the pins 24 on. the tooth. The backing is then placed over the pins as in Fig. 6, and to make it fit tightly down thereon and burnish it, one of the arms 15, provided with a perforation 16 to tightly lit the pin on the tooth being treated, is placed over the pin and a pressure exerted thereon, and the tool is rapidly twisted to the right and left, and in this way the backing is flattened out at pins and is caused to he very close to the tooth. 1 next subject each pin to pressure from the ends of the arms 12, where the recesses .14 will engage each pin 24 and flatten it out, and. force it down on the backing 25, as shown in Fig. 7, the flattened portion 27 of each pin not only locking the backing against removal, but if the work is done close up, the spread .ing will force itself down on the backing, and serve to bind it tighter against the artificial tooth 23.

In Fig. 8 I show sections of the pins, one before it has been distorted or upset by the pliers, and the other showing the result of the treatment by the pliers. The pins 24 are now cut oil by setting them in the recess 18 of the plate 141, when the jaws 12 are open, and then operating the handles 10 to bring the jaws together, whereby the pins are cut off close up to the backing 25, leaving sufficient of the pins to form a slight head. If desired, one of the pins 24 can be passed down through the perforation 20 in the lip 19, and the tooth will be held. better while the cutting is taking place.

Fig. 9 shows a finished article having the.

tively to perform each step in the process of affixing an artificial tooth by means of the pins, the backing and the solder, now commonly employed by dentists in this process.

Having thus described my invention, what I claim is 1. A dental tool comprising a pair of hinged'members having handle portions, the free ends of the jaws of the members having abutting faces adapted to distort a post, a pin projecting from one of the members, a plate secured to one jaw and arranged to shear in conjunction with the other jaw, and burnishing arms on the plate provided with perforations for the reception of a post.

2. A dental tool comprising a pair of hinged members having handle portions, the free ends of the aws of the members having their abutting faces provided with recesses placed slightly out of alinement to distort a post pressed between them.

3. A dental tool comprising a pair of hinged members having handle portions, the jaws of the members having their abutting faces recessed to distort a post pressed between them, and a plate secured to one jaw and adapted to have a shearing action on the other jaw to out off the post.

4. A dental tool comprising a pair of hinged members, the jaws of the members being arranged to distort a post placed between them, a plate secured to one jaw and having a shearing action with the other aw, the shearing edge of the plate being recessed, and burnishing arms projecting from the plate beyond the jaw and having perforations therein. c

In testimony, that I claim the foregoing, I have hereunto set my hand this 15th day of March 1907.
