    Newmans Improvements in the Construction of Artificial Teeth, §c. for repair without moving the others or “passing through the fire.’* A comfortable and neat fit, with great strength, are the advantages of this Invention. I make the fronts or that part of the teeth shewn, when in use, of porcelain 5 or any of the other substances at present used, and the backs of metal or other hard and tenacious material; these I fasten together by various mechanical con¬ trivances, say, by the pins, usually moulded or cast in teeth, screws, rivets, part of the back cast or moulded into the fronts, or by an adhesive material. The backs consist of a plate, with an aperture, forming a short tube made therein, 10 or fastened thereto, or simply a plain tube; the plate may cover the whole or part of the tooth, and the tube, made of any shape or configuration to suit the mould, may be shortened at either end. The frame or palate has studs or pins fastened therein, which are made of the same shape and configuration as the apertures or tubes on the back of the teeth; by passing these studs through the 15 apertures referred to, and rivetting or otherwise fastening, the teeth will be affixed on the frame and ready for use without further support. Where gutta percha, india-rubber, or other flexible frames or palates are used the same con¬ struction is retained, either with metal backs, tubes, and stubs, or by having a tube formed of the material used fastened to the back of the tooth, and a 20 metal or other inflexible stud. These my improvements will be better understood, reference being had to the Drawings accompanying this, and to the letters of reference thereon. In all the views the same letters of reference represent the same parts. Fig. 1 represents a back view, Fig. 2 a side view, Fig. 3 a plan, and Fig. 4 25 a vertical section of one of my improved teeth, with the plate entirely covering the back thereof, and the tube partially shortened ; Fig. 5 a back view, and Fig. 6 a vertical section, of another modification, the tube being fastened to the pins usually cast in teeth; Fig. 7 a back view, and Fig. 8 a vertical section of another modification, the plate partially covering the back of the 80 tooth and tube, the latter being embedded in the front part; and Fig. 9, a front view of a set, with two teeth removed, shewing the studs for affixing to the frame, a represents the porcelain or other light-colored front; h, the plate ; c, the tube ; d, the frame ; e, the stud. Although I have described the nature and particulars of my said Invention, 35 and the manner of performing the same under several modifications, still 1 do not confine myself thereto, as such may be varied and further modified without departing from the principle of the same; but what I claim as my Invention, and which to the best of my knowledge and belief has not been hitherto used
