ELECTRICAL cboKING UTENSIL.

.To all whom t may concern:

BeA it known that I, ALF'gnED B. ANTISELL,^ a citizen of the United States, and resident .of New Yorkcity, in the county of New York and State of New York, have invented certain new and useful improvements in Electrical Cooking Utensils, of which the following is a specification.

This invention relates to improvements in electric cooking utensils and has particular reference to an improved electrically heated vessel for quickly warming liquids, 'though y vits use is not limited thereto.

The object of the'inventionis to provide a generally improved cooking utensil or vessel adapted to be heated electrically and comprising such features of improved construetion as are hereinafter set forth and as illustrated in the accompanying drawing in which, f

Figure.

1 is a view of an electric cooking i utensil embodying the invention, parts being in elevation and parts in section. F1g. 2 is a horizontal sectional viewrthroughthe handle and Fig. 3-is an enlarged view of the y terminal connections of the heating element.4

.The utensil or vessel comprises an inner ,shell 4 and an outer shell l5, each preferably of copper and nickel plated.` The inner shell is provided withv aj rim or bead 6 within which the router shell 5 is secured by `'any 1 suitable means', as lby soldering, welding,

crimping or otherwise.

This may be done by heating the an' therein, so that after 'cooling a partial vacuum exists in space 10, or'the 'vacuum may be obtained by othermeans and serves as a non-conductor of the heat :from the coil 7. rLhe terminals of the coil 7.consist of separate strips 11 and 12 of conducting material, for instance brass. -The strips 11 and 12...

are laid between the -coil 7 and `the cementY layer 8 with a piece of nonfconducting mate` rial 13, forIr instance mica, between the coil and the terminals as clearly shown in Fig. 3.

The upper inner end-of the terminal 11 is electrically connected at 14 to the upper turn with force so as to make a good electrical vided to keep the rods 2O inconstant touch vwith the terminals. rPhe rods are further insulatedv and positioned in the handle by-a liber washer 23 and nuts 24, the ends 425 of lightvsocket, all of'which is not shown". l

The utensil as herein described and illus trated may be made quickly ata low cost and tests. have shown that liquid in the vessel is quickly and 'economically heated when` the l current is turned on.

- The detailed construction maybe changed and: the invention is not limited to the precise manner of making or the forms of parts as illustrated otherwise thanrequired'by the lscope of the appended cla' s. vIela .i m:

1. A utensilil of thev characterl described .comprising an inner and an .outer sll'ell, a heating element carried by said inner-shell, vy aninsulating covering over saidheating ele-` ment, separatev terminal vpieces 'secured to said heatlng element and bent vto lay' on the loutside of said insulating covering, ahandl'e secured'to 'saidv outer shell and terminal rods s in said handle secured therein and in contact described comprislng an inner and an outer shell se- A 'cured together to form acha'mber, in which with the said terminal pieces.

2. A utensil of thel character a partialvvacuumis createdaheating element` around saivd inner she11,iusulatin'g ma-A yterial on both sides of said heating element,

separate terminal pieces electrically connected at the ends of said heating element and secured between said heating element `and the insulating material on the one side therelof, a handle securedto said outer shell, terminalrods in said handle projecting ining outside said coil of wire, terminal pieces secured between said coil and said cementitious-A material, insulating vmaterial between said coil of'wire and said terminal pieces, which latter are connected respectively to the upper and lower turn of Wire in said coil, said terminal pieces being further bent to lay on the outside of said insulating covering, a handle secured to said outer shell and terminal members secured in said handle in contact with the said terminal pieces.
