    N° 10,016 A.D. 1898 Date of Application, 2nd May, 1898—Accepted, 1st Oct., 1898 COMPLETE SPECIFICATION. Dental Appliance. I, Israel Stewart Kirkwood, of 41b, New Fru Buildings, Chicago, in the County of Cook and State of Illinois, one of the United States of America, Dentist, do hereby declare tlie nature of this invention, and in what manner the same is to be performed, to be particularly described and ascertained by the follow- 5 ing statement: — The invention relates to a stand or bracket, and apparatus carried thereby or accessory thereto, for the convenience of a dental table, comprising a box for the holding of absorbent or sterilized cotton and the stripping and reception of saturated wads, trays for the reception and separate support of cylinders or pellets 10 of gold or other filling material, means for warming said trays; means for heat¬ ing alloy or amalgam ; means for moistening or damping drills or burrs, and various other facilities. In dentistry it is of importance to keep the cylinders or pellets, and so forth, of fresh, unused annealing gold or silver or of gutta percha apart, since they 15 anneal or combine if brought into contact; therefore I form the trays for their reception with dividing ridges, corrugations or pockets in which each cylinder or pellet or other form is kept isolated from the next. One of the trays holding cylinders or pellets is so formed that it will receive the ends of the nippers or pluggers, or other instruments, which are supported upon a rack projecting from 20 the stand and movable therearouud to accommodate itself to the position of the tray. A sponge cup, and a cotton case for both fresh and refuse cotton, are also mounted on the stand and swingable thereabout. A hot water tank and a gas jet to heat it are also provided. In the drawings; 25 Figure 1 is an elevation of a stand embodying my invention; Figure 2 is a top plan view; Figures 3 and 4 are details; Figure 5 represents a tray for sterilizing burrs and like small instruments, and 30 Figure b is a front view of the cotton box. A represents a base in which is supported a vertical standard or post B. Upon this post, suitably spaced by sleeves b, are swinging sockets C, each adapted to hold a removable crane-like arm for the support of a tray or other device. Commencing with the lowest agency of the apparatus, 1) is a burner supported 35 at the end of the crane-arm d, and having nipple dl whereby it is secured to the flexible tube l)1 leading to a gas jet; air ports d? are provided in the burner to give an intense flame instead of an incandescent one, and by means of the socket and crane-arm it can be swung in any direction around the standard. E is a shield mounted in such manner that it can be swung to follow the burner, 40 or to go on opposite sides thereof, to guard it from air currents, and F is a cotton- box which is shown as made in two sections Fx and F2, and preferably cylindrical in shape, since this or some other rounded outline is best adapted to thorough cleansing and disinfecting. The section Fx is intended to hold saturated wads and refuse and is closed at one end only and at its other end is dammed by a low 45 barrier f, which serves to confine the refuse wads, the saliva etc., until inten- [Price 8d.~\ • - «
