ROBERT F. WHER'LAND, OF STANLEY, NORTH DAKOTA.

ELEGTRICALLY-HEATED APPARATUS.

T 0 all whom it may concern:

Be it known that I, ROBERT F. WHERLAND, a citizen of the United States of America, residing at Stanley, in the county of Mountrail and State of North Dakota, have invented new and useful Improvements in Electrr cally-Heated Apparatus, of which the fol lowing is a specification.

This invention relates to an electrically heated apparatus, and the object is to provide a device of the type indicated, which shall be especially adapted for use in a battery service station, for heating battery compound.

A further object is to providea device of the character indicatedwhich shall include a receptacle provided with a main interior chamber for the compound, a pouring tube connected therewith, said tube enclosing a heat conducting element, having connection with a duct passing through the main chamher, and an electrically heated device enclosed within said duct.

A still further object is to provide, broadly, an electrically heated device, for the purpose indicated, in which the material to be heated shall be placed under, or sub jected to, a high temperature, not only with in the main chamber of the apparatus, but also in the discharge spout, whereby the required fluid condition is maintained as long as possible.

With the foregoing and other objects in view, the invention consists in the novel construction, combination, and arrangement of elements hereinafter described and claimed.

In the drawings, Figure l is atop plan view of the device, and Figure 2 is a View in vertical section and side elevation.

In carrying out my invention, I provide a receptacle of any suitable form and capacity, the form shown in the drawing being adapted for the purpose indicated. The main portion of the receptacle is designated 10 and a cover 12 is provided therefor, and likewise a handle 13.

A tubular element 14 connects with the inner chamber of the receptacle and has connection with a discharge spout 15. The latter may be supported by a handle 16. A layer of asbestos 17 is shown as being located in the lower portion of the chamber 10, and serves as a nonconducting element. Within the tubular element 14 is a duct 20, extend- Specification of Letters Patent. Pat t d J 1 1922.

ing to a point above the element i l and havlng connection at its lower end with the d not 21 which passes through the main chamber and preferably in an inclined direction.

I-Ieated air passes through a duct or housmg 21 and thence upwardly through the duct 20, so that the compound within the element 14; is maintained at a temperature approaching the temperature in the main receptacle. An electric heating unit includes a member 24 receiving current through connections 25 and 26. A cord for connection with a source of current supply is designated 27, the usual plug 28 effecting the connection with the terminals of the resistance coil.

In actual use the device. has proved to be highly eflicient, and the fact that the compound is poured from a point below the surface is of importance since the impurities collecting on the surface are not poured off, as with the use of a ladle.

While the duct 20 maintains the heat to the required degree, it is so proportioned that the heat of the compound will not be excessive when being discharged.

TV hat I claim is:

l. A device of the class described, comprising a receptacle, a duct extending transversely therethrough, a discharge spout, a tube extending through said spout and having connection with the aforesaid duct, and an electrically heated element within said duct.

2. A device. of the class described comprismg a receptacle a discharge spout therefor, an electric heating unit within the recep tacle, and means for conducting heated air from said unit through the discharge spout.

A device of the class described comprising a receptacle, a cover therefor, a tubular member connected with one sideof the receptacle at a point below the top thereof, a

housing within the receptacle, extending transversely thereof and having one end open, the opposite end projecting into the tubular member, an air duct extending from said housing through the tubular member, a discharge element projecting from said tubular member, and handle connected with the discharge element.

In testimony whereof I afIiX my signature ROBERT F. WHERLAND.
