B. E. GRUZEN. ELECTRIC HEATER.
Patented Feb. 1, 1898.
if 2 N6 P6. M
VCAAA/JVLLQM UNITED STATES PATENT OFFICE.
ELHOR E. ORUZEN, OF BALTIMORE, MARYLAND.
ELECTRIC HEATER.
SPECIFICATION forming part of Letters Patent No. 598,303, dated February 1, 1898.
Application filed August '7, 1897.
cleansed preparatory to being filled. It is important that this canal, which in some teeth is tortuous instead of straight, be effectually dried before inserting the filling. Efforts to eifect this drying have been attended with difficulty, and the methods resorted to have proved ineffectual. To accomplish this drying of the whole length of the canal quickly, I have provided a flexible metal probe which may be inserted while cold into the root-canal, heated by electricity to expel all moisture in the canal, and then withdrawn.
The instrument is shown in the accompanying drawings, in Which- Figure 1 is a side view of the electric drier. Fig. 2 is an end view of same.
The instrument is intended to be held in one hand of the operator, while a flexible probe heated by an electric current is inserted into the nerve-cavity or root-canal of the tooth, where its heat dries out the moisture in the canal.
The letterA designates an insulated handle containing two metallic conductors, which extend longitudinally through the handle and Serial No. 647,428. (No model.)
construction and operation of these parts in the handle are well known and are not deemed necessary to be shown in the drawings, as they are not my invention. Attached to the couplings Z9 Z9 at that end near which the pushbutton 0 is located is a loop or return-circuit Wire d, more or less of which is covered with a wrapper e, of insulating material. At the extremity this loop for a short length is composed of fine wire cl or wire much smaller in cross-section than the other portion which has the insulating-wrapper e. lVhen the electric current is on, the fine-wire extremity d becomes heated.
Iprovide aprobef, of copper or similar flexible metal, thicker at one end and tapered to a point at the other end, and attach the thick end of the probe to the fine-wire extremity d of the loop, which is of higher resistance. By this construction the pointed end of the flexible probe may be readily inserted into the root-canal of a tooth even where the canal is tortuous, and the probe f will be heated by the electric current, and the heat of the probe will quickly dry out any moisture in said canal and put it in condition to be filled.
Having thus described my invention, what I claim is An electric heater for drying canals in the roots of teeth, comprising an insulated handpiece; two wires of an electric circuit passing through the handpiece'and projecting from one end thereof and covered and lashed together by an insulating-wrapper,e, and a wireloop extremity of said circuit of higher resistance; and a metal probe, f, attached by one end to said high-resistance extremity and having a flexible point, whereby the probe may be inserted in the root-canal and heated by an electric current, as set forth.
In testimony whereof I affix my signature in the presence of two witnesses.
ELMOR E. CRUZEN.
