Application March 16,

4 Claims.

This invention relates to new and useful improvements in heating devices generally, although more particularly to electric melting pots for substances having relatively low melting pointssuch as ordinary solder.

The principal object of my invention is to provide'an electrically heated melting pot to be used .in soldering the ends of electrical conduc tors. e

Another object of my invention is to provide a device of the abovecharacter' which will ret'ain a-relatively large amount of heat for a maximum time. I

Another object of my invention is to provide a d'e'vic'e of the above character which is simple in construction and economical to manufacture.

With these and other objects in view which will more fully appear, the nature of the invention will be more clearly understood by following the description, the appended claims, and the several views illustrated in the accompanying drawing.

In the drawing:

Figure 1 is a vertical section of a heating device constructed in accordance with my invention,

Figure 2 is a top plan view thereof,

Figure 3 is a horizontal section taken on line 33 of Figure 1, and

Figure 4 is a bottom plan view of the covering sleeve.

Like reference numerals designate corresponding parts throughout the several figures of the drawing.

Referring to the drawing in detail, my invention includes a support 5, an electrical socket 6 secured thereto, a heating element 1 mounted in the socket, and a handle 8 secured to the support.

The support 5 is preferably a standard octag- 40 onal electrical outlet box and includes a top 9 provided with an opening Ill, a bottom II, and sides I 2.

The socket 6, which is preferably of the standard screw-base type, is secured on top of the support by the bolts 13, I3. The socket includes a base l4 made of non-conducting material, such as porcelain, but has its base shell enclosed in a removable open ended porcelain sleeve IS, the sleeve being interiorly threaded to engage the exterior threads on the sleeve. The upper surface of the base forms a stationary clamping device of which the complemental removable element is the sleeve IS.

The heating element 1 is vertically disposed and is threadably engaged in the socket 6 and 1938, Serial No. 6,283

includes a core i! of porcelain or analogous material, a metallic screw plug base l8, and a coil E9 of resistance wire disposed around the core and having its ends attached to the plug base I8 in the usual manner. The core ii is provided with an axially disposed cylindrical recess 28 extending downwardly from the upper end thereof. The lower half of the recess is filled with heat resistant material, such as asbestos plaster.

A frusto-conical covering sleeve 2| of sheet metal surrounds the heating element and is spaced therefrom, the sleeve being provided at its lower end with a plurality of inwardly bent ears 22. These ears are located between the lower end of the sleeve l6 and base [4 and clamped therebetween. The space between the heating element and the covering sleeve is filled with insulating material 23 such as asbestos to assist in retaining heat in the device when in use.

When the device is to be used, electricity is brought to the heating element from a source of power through the medium of an electrical plug 24 mounted on the support and connected to the socket 6 by leads 25, 25 in the usual manner. Solder 26 is then inserted in the recess 20 of the heating element and then melted. The joined ends of the conductors which are to be soldered, are then immersed in the melted solder and then withdrawn therefrom whereby the joint Will be evenly coated with solder.

The handle 8 is resilient in its action to provide a means whereby the device may be easily and conveniently clamped to any desirable supporting structure to hold the same in close proximity to the work.

Thus it will be seen that I have constructed an electrically heated melting pot for soldering joints in electrical conductors which is heat retentive and which is simple in construction and economical to manufacture.

It is of course to be understood that the details of structure and arrangement of parts may be variously changed and modified without departing from the spirit and scope of my invention.

I claim:

1. An electric heating device comprising the combination of a support, an electrical socket mounted on top of the support and including a base of non-conducting material and a metallic shell upstanding therefrom and shaped to provide both interior and exterior threads, an internally threaded sleeve removably engaging the exterior threads of the shell and having its lower 2. An electric heating device comprising th V combination of a base member, an electrical contact carried by said base member including an insulated base and vertically disposed screw threaded socket, a heating element including a resistance coil terminating at one end in a plug threadedly received within said socket, a receptacle positioned within said resistance coil and opening through one end thereof, an external shell, insulated from and enclosing the coil, said shell being formed at its upper end with an opening registerable with the open end of the receptacle and at its bottom end with an inwardly extending annular flange engaging the insulated base circumjacent to the socket, and a sleeve threadedly received exteriorly of the said socket and engaging the annular flange of the said 3. An electric heating device comprising the combination of a base member, an electrical contact carried by said base member including an insulated base and vertically disposed screw threaded socket, a heating element including a resistance coil and a plug threadedly engaged within said socket, a receptacle positioned within said resistance coil and opening through the end thereof remote from the said plug, an exterior cover insulated from and enclosing the coil and formed with an opening registering with the opening in the receptacle, said cover being formed at its bottom end with an inwardly extending annular flange, a sleeve threadedly received exteriorly of the said socket and engaging the annular flange of the said cover to hold the same against displacement, and handle means secured to the said insulated base.

4. An electric heating device comprising the combination of, an electrical contact including an insulated base and vertically disposed screw threaded socket, a heating element including a resistance coil one end of which terminates in a plug threadedly engaged within said socket, a receptacle positioned within said resistance coil and opening through the end thereof remote from the said plug, an exterior cover thermally and electrically insulated from and enclosing the coil and formed at one end with an opening registering with the open end of the receptacle andv at its other end with an inwardly extending annular flange bearing against the base circumjacent to the said socket, a sleeve threadedly received exteriorly of the said socket and engaging. the annular flange of the said cover to hold the same against displacement, and means carried by the said insulatedbase to permit they said heating device to be detachably secured to any suitable support.
