ARTIFICIAL TOOTH.
SPECIFICATION forming part of Letters Patent No. 429,285, dated June 3, 1890. Application filed December 24, 1889. Serial 110.3%,901. (No model.)
To all whom it may concern:
Be it known that we, ALFRED PAGE, a citizen of the United States, and SAMUEL S. BLOOM, a citizen of Russia, both residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Artificial Teeth;
and we do 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 the letters of reference marked thereon, which form a part of this specification;
Our invention relates to improvements in artificial teeth; and it consists in the provision of novel means or provisions for securing the rubber plate to. the teeth or gum. Pins set transversely in the teeth and projecting inwardly past the teeth to afford a hold for the rubber plate are well known in the pro- I fession and trade, and to secure such pins it has been customary to insert them when the material is being molded andbefore it is baked. This necessitates the use of platina pins, as no other material will withstand the heat of the annealing or baking process. The use of platina pins involves a great cost, as the material is expensive. By reason of our invention we are enabled to secure just as good results without this heavy expense.
In carrying our invention into practice we provide a small platina tube or cylinder of coiled Wire, which is inserted in the teeth before baking, and after the tooth is baked we secure a pin, of silver or other suitable and less expensive metal, in the tube or cylinder. In any case the amount of platina necessary to secure the result is very materially diminished, while the efficacy of the device is in nowise impaired.
The accompanying drawings illustrate the manner of carrying our invention into practice.
Figure 1 is a longitudinal section of a tooth, showing a section of plain platina tube. Fig. 2 is a similar section showing a threaded tube. Fig. 3 is a similar section showing an elevation of a coil-wire tube. Fig. 4 is a section corresponding to Fig. 1, showing the pin in place. Fig. 5 is a section corresponding to Fig. 2, showing the pin in place. Fig. 6 is a view corresponding to Fig. 5, showing the pin in place. Fig. 7 is an inside elevation of a tooth, showing the end of the tube.
Similar letters of reference indicate corresponding parts in all the figures where they occur.
A is the tooth, and B the tube or cylinder of platina, which is placed therein when the tooth is being molded from the plastic material. This tube or cylinder may, as already stated, be plain, as shown in Fig. 1; or screwthreaded interiorly, as shown in Fig. 2; or it may consist of a coil of platina wire, as shown in Fig. 3, which latter may be formedbycoiling it over a rod of the same diameter as the pin, which is afterward to be inserted in it. The wire coil may perhaps be found the most economical as well as the best form for being retained in the tooth, and in turn for retaining the pin, as it gives the best holding-surface.
O is the pin, which is preferably formed of silver oi some other suitable metal, and may be fastened in the tube by means of solder, as would be the case with the plain tube shown in Figs. 1 and 4, or with the coil-wire tube of Figs. 3 and 6; or it may be threaded into a threaded tube, as would be the case in Figs. 2 and 5.
The coil'wi e form shown in Figs. 3 and 6 may be secured without solder by having a thread formed on the pin corresponding to the coil of the wire.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is
The combination, in an artificial tooth, of a tube formed of coiled platina wire and a pin secured in said tube, as set forth.
I11 testimony whereof we affix our signatures in presence of two witnesses.
ALFRED PAGE. SAMUEL S BLOOM.
