(No Model.) G. E. BROOKS. DENTAL APPLIANGE. No. 336,790. Patented Feb. 23, 1886. UNITED STATES PATENT OFFICE. CHARLES E. BROOKS, OF BROOKLYN, NEW YORK. DENTAL APPLIANCE. SPECIFICATION forming part of Letters Patent No. 336,790, dated February 23, 1886. Application filed November 17, 1885. Serial No. 183,065. (No model.) To all whom it may concern.- Be it known that 1, CHARLES E. Baoons, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Instrument or Appliance for the Use of Dentists or Surgeons, of which the following is a specification. My invention consists of a post or posts, preferably a tube affixed to the floor, ceiling, or walls of the operating-room or to the operating chair or table, as may be most convenient, and in such manner as to be either stationary or movable, and adjustable, preferably,on a movable foot provided with adjustable spring arms and branches; and the object of my invention is, first, to provide a steady, continuous, and uniform pressure in any desirable direction, at the same time allowing the parts so held, pressed, or attached to be moved at pleasure; second, to afford facilities for filling cervical dental cavities in upper or lower teeth by retaining in position the rubber dam or apron S, and thus more surely preventing a flow of salivainto cavities which are being operated on, increasing the comfort of the patient, and the convenience of the operator, and the certainty of the operation; third, to hold parts in any desirable position for indefinite periods with steady tension, while allowing change of position of the subject in surgical operations or dissection, to the end that they may be more properly examined and treated. I attain the results and advantages above specified by the mechanism or contrivance illustrated in the accompanying drawings, in which- 1 Figure 1 represents an elevation of the complete apparatus, and Figs. 2, 4, 5, and 6 show elevations, and Fig. 3shows a ground plan,on a larger scale, of parts of the device. Like letters in the different views indicate corresponding parts. A is a plate fastened in position, preferably to the floor, near the operating chair, by a screw or bolt, B, so arranged that it can be moved longitudinally in the slot 0, and also allow the plate A to revolve horizontally, as may be desirable. The edges of the plate A are so turned over as to makea groove on each side of the plate A in such manner as to hold the movable foot or shoe D, "and allowing to it a longitudinal motion only, by which means the post maybe made to assume any position within the radius of the plate A. Into the foot or shoe D is fastened, (pref. as a hook, ring, pliers, &C.--Wl1l0h attachment may be either permanent or detachable. To said attachment may be fastened a cord, Q, attached t0 apron S. At F or near the end of the post E is a small set-screw, to prevent the slipping of the spring 1?. G G are movable swivel-clamps, of which one or more may be used, so arranged as to slide lengthwise on said post E, holding similar or suitable wires or springs of desirable length in any desirable position, as shown in Figs. 2 and 6, in which G is the slide held in place by the set-screw H. On any side of the slide G is a ball-and-socket or other suitable joint, I, to which is attached a short tube, K, which may be retained in any position by the setscrew N. Passing through the tube K is a spring wire or wires, L, in Fig. l, of any convenient length, with any desirable attachments at its ends, said wire L being retained in position by the set-screw R. Fig. 4 represents an end view of the plate A with the movable foot or shoe D in position. Fig. 5 represents the movable foot or shoe and the foot of the post E. Figs. 2 and 6 represent the movable swivelclamps. I claim as my invention and desire to secure by Letters Patent- In a dental apparatus, the post E, having the movable and adjustable foot or shoe D, and provided with the spring P and swiveled spring-rods L and L, substantially as for the purposes set forth.
