1 Claim.
My invention has relation to improvements in cauterizing instruments and it consists in the novel features of construction more fully set forth in the specification and pointed out in the The object of the present invention is to provide a cauterizing instrument especially for removing Warts, moles and similar skin blemishes, said instrument being of the general shape of a pen or pencil so that it may be conveniently held in the hand, which instrument will comprise a holder and a series of points so constructed as to be interchangeable so that a point of any desired shape may be used according to the size and nature of the blemish that is to be cauterized.
A further object of the invention is to so construct the cauterizing instrument that the heat 0l' the cauterizing point may be readily controlled.
Further objects, such as simplicity and dura- ;0 bility of the device, will be better apparent from a detailed description of the invention in connection with the accompanying drawing, in which:
Fig. 1 is an elevational view of my improved ,5 cauterizing instrument; Fig. 2 is an enlarged medial, longitudinal section taken on the line 2-2 of Fig. 1, with parts left in elevation; Fig. 3 is an enlarged longitudinal, sectional view of the point of the instrument with the heating coil 0 left in elevation; Fig. 4 is an enlarged longitudinal section of the point of the instrument taken on a plane indicated by the line 4-4 of Fig. 3; Fig. 5 is a perspective View of the core of the heating coil; Fig. 6 is an elevation of the tip of the 5 pencil showing an auxiliary cauterizing point applied thereto; and Figs. 7 to 10, inclusive, are detached views of different forms of auxiliary points that may be applied to the main tip of the instrument.
0 Referring to the drawing, my improved cauterizing instrument comprises a holder I, a tip 2 and a removable point 3 secured in said tip. The holder I comprises an elongated tubular member of a size that may be conveniently held in the 5 hand and is preferably formed from insulating material, such as bakelite or other material having equally good insulating properties. One end of the holder I is provided with a screw-threaded socket 4, in which is screwed a plug 5, and the D other end of the holder is provided with a screwthreaded socket 6, in which is screwed the threaded stem I of the conical tip 2. The cauterizing point 3 comprises a tubular shell formed of some metal that has high heat conductivity and has a 5 screw-threaded portion 8 threaded into the end of the tip 2 and a conical flange 9 flush with the surface of the tip 2 when the point 3 is securely in place. A heating element I0 fits snugly within the hollow point 3, said heating element comprising a hollow core I I formed of insulating ma- 5 terial that has high heat resistant qualities and a coil I2 (preferably of nichrome wire) wound on the intermediate reduced portion I3 of the core. The ends of the core II are provided with slots I4 and I5 on one end and slot I6 on the opposite 10 end, and in winding coil I2 the wire I1 traverses the center opening I8 in thecore II and is bent through the slot IB at the outer end and connecting slot I6', and after being wrapped around the core the wire is brought through slots I5 and 15 I5 so that both ends of the coil are at the same end of the yheating element for simplicity of connection with the ends of the conductors I9 and 20 which lead to an outlet or other source of electrical supply.
The slots I4, I5, I5', I6 and I6 are filled with suitable insulation 2| so as to effectively insulate the wire I'I of the heating coil, and suitable insulation 22 is wrapped or otherwise disposed over the coil around the core II. In order that the operator may be able to control the temperature of the point 3, a switch is provided on the handle I, said switch comprising a contact 23 secured in place by a rivet 24, a spring contact 25 secured in place by a rivet 26, and a push but- 30 ton 21 operable against the spring contact 25 so that pressure thereon will separate the contacts 23 and 25 and open the circuit, giving the coil Ill and of course the point 3 an opportunity to cool somewhat. The switch comprising the parts just described is connected in one of the conductors I9 or 20 (in the present instance conductor I9 is opened to receive the switch). In order that there will beno strain on the connections of conductors I9 and 20 with the heat- 40 ing coil wire I1, a. stop element 28, which may be either a knot or a wrapping of tape or any equivalent device, is provided on the conductors I9 and 2D for engagement with the plug 5.
In Fig. 6 I show an auxiliary point 29 con- 45 siderably sharper than the point 3, said point having a socket 3l) which receives point 3 snugly so that in operation the heat of the point 3 will be communicated to the point 29. In order that this heat may not unduly raise the temperature of the tip 2 of the holder, I provide two series of openings o and 0' in close proximity to the threaded stem 8 of the point 3 through which the heat may be vented.
A screw-cap 35 (similar to that on a fountain 55 pen) is positioned over the point 3 when the instrument is not in use, and is held in place by the threads 36 on the holder.
In Fig. '7 I show a slightly diierent .shape of auxiliary point 3|, and in Fig. 8 I show a needle point 32, and in Fig. 9 a. slight variation and somewhat larger point 33 than the point 3 I, while in Fig. 10 I show a knife-shaped point 34. Obviously, any number of shapes or sizes of points may be utilized, and I do not wish to be restricted to the specific points herein illustrated and described.
Having described my invention, I claim:
A cauterizing instrument comprising a handle, a tip secured in one end of said handle, a cauterizing point removably fixed in said tip, said point comprising a hollow metallic member, and a tubular heating coil disposed therein in contact with the inner wall of said member, and an auxiliary point disposed over and in contacting relation with said hollow metallic member, and
suitable electric conductors connected to said coil 10 and passing through the handle.
GEORGE DINYER.
