lgmom Ziodo .Zldef citizen of the United "States,
stant temperature by arena ornron TIODOLF LIDBERG, OF. CHICAGO, ILLINOIS.
asaosa To all whom it may concern:
Be it known that I, TIODOLF LIDBERG, a
residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Therapeutic Instruments, of which the following is a specificat1on.
My invention relates to improvements in 'electro-therapeutic instruments for orificial application, whereby to maintain constant, any desired temperature, of the operative portions of the instrument, preferably below that required to cauterize or directly destroy the tissues with which it may be brought into contact.
One of the especial objects of my invention is to provide an instrument of this character adapted for medical treatment, and especially for orificial application, whereby to automatically maintain a constant, but regulable temperature, by means contained in the heated zone, or preferably within the applicator of the instrument, near the point of application, and to pro vide, in such an instrument, a heat-responsive temperature indicator, preferably withinthe applicator, and having an exterior portion located outside of the applicator,
provided with suitable graduations that it may be visible at all times to the operator or attending physician, whereby the temperature of the applicator is indicated.
Another object of my invention is to provide two or more applicators, capable of being connected together and automatically controllable to maintain, substantially, cona single heat respon-' sive regulator.
Other, and further objects of my invention will become readily apparent, to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein:--
The spring blade 49 extends vertically,
- substantially parallel with the heating coil 22, and has its remote end inturned, asat 70, to provide a means for connection to the terminal 71 of the spring'jack switch plug 28. The switch plug terminal 71 is connected to a wire 72, and the switch ring or terminal 27, is connected to a wire 73, for
connection to another applicator of similar character, or to an applicator 74, as shown. The applicator 74 consists of a two part spectively, so as to be removed from the head 82, to connect and to disconnect the heating coil 7 8. The wires 72 and 73, of a duplex cord, are connected to the terminals 85 and 86, respectively, and are also connected to the terminals 27 and 71 of the Specification of Letters Patent. Patented Sept, 24L, 1918,, Application filed December 18, 1916. Serial No. 137,48
spring-jack plug 28. When it is desired to connect the heating coil 78, of the applicator 74:, in circuit with the'heating coil 22 of the applicator 11, it is only necessary to "insert the plug 28, into position shown in the figure. When the applicator 11 is to be used alone, then the cap 69 is removed from the upper end of the applicator tube 65 and a similar imperforate cap is substituted.
When the applicator 74 is being used the instrument containing the current-regulator may be hung upon the wall or supported in any other convenient manner adjacent to the position of the applicator 74.
While I have herein shown a single embodiment of my invention, for the purpose of clear disclosure, it is manifest to persons skilled in the art that many changes may be made in the general arrangement and configuration of the parts within the scope of the appended claims.
Having described my invention, what I claim is:-
1. An electro-tlwrmie applicator comprising a heatingelement; a heat-responsive, cul'rent-eontrolling regulator: a tube. or jacket closed at one end. covering said instrumentalities and having a replaceable perforated cap through which to insert a connecting plug, a graduated temperature indicator, the graduations of which are without said jacket, and a connecting plug bearing terminals whereby to connect another applicator to the circuit, including said regulator, within said jacket.
2. An electro-thermic applicator comprising an elongated tube having a closed, curved end; a heating element therein localized in the curved end of the tube leaving the straight portion thereof relatively unin a plug receptacle and a connecting plug, heated, and-wires connected to the heating bearing terminals to connect said applicaelement passing through the straight portor to an electric circuit. tion of the tube.
