ELECTRIC TOASTER. I

Speeifiiiation of Letters Patent. P t t 1 Application filed Ka 1, 1909; Serial no. 493,410. Renewed and 21, 1910, Serial 550,807.

To all whom 'it may concern.

Be it known that I, WILLIAM S, Han-r WAY, J12, a citizen of the United States, and

a resident of East Orange, in the county of Essex and State of New Jersey, have invented anew and useful Improvementin Electric Toasters, of which the following is a specification.

My invention relates to electric resistance or heating devices, and it has for its object to provide a simple and durable electric toaster so constructed that slices of bread or other articles to be toasted may be subjected to the directheat of the current-conducting element Figure 1 of the accompanying drawings is a plan view .of a toaster constructed in accordance with my invention, certain of the parts being broken away to disclose a portion of: the resistance element. v Fig. 2 is a side elevation, Figs. 3, 4, 5 and 6 detail views and Fig. 7 a fragmentary perspective view, of the device shown in Fig. 1.

Referrin to the. drawings, the structure here illustrated comprises a substantially rectangular supporting frame'l, having side strips 2 and 3 and end strips 4 and5 that are supported at their corners by brackets 6 which project downwardly to constitute feet on whichthe structure rests, and a plurality of stamped or punched cross bars 7 which are supported at their ends by the side strips 2 and 3. l 3

Each of the cross bars 7 is formed from a strip of sheet metal whichis criinped longitmlmallyqinto an S-section and its edges are bent v.in opposite directions, at right migles to its body portion to form flanges 8 upon which slices of'bread, or other articles to be toasted, may be laid. The body portions of the bars are-cut back so that the ends of the flanges form projections 9 which extend through suitable perforations 10 in the side strips 2 and 3 and are bent over to hold the parts togetherv (see Fig. 7).

The resistance element comprises a strip or ribbon 11 of steel or other suitable resistance material having a pluralitvof lateral slots 12 cut alternately from opposite edges to form a zig-zag path for the elecorder to expose a maximum area of the rib b011, strips 13 ofniica or other suitable in sulation arefolded overthe edges of each section, the insulated edgesYbeing then in serted in the grooves 1st whichare formed by the crimps in the cross bars. The slotted sections of the resistance ribbon are joined by low resistance sections 11 which are bent back to avoid making contact with the side strips 2 and 3. The terminalsof the resistance ribbon are clamped to

connectors

15 and 16 that are secured to and insulated from the corner brackets 6.

Since all of the partsof my toaster are punched or stamped, no machine work is required and the manufacturing cost is materially reduced.

It is evident that modifications may be effected in the size 'of the structure shown and described and in the urrangements'of its parts without departing from the spiritof my invention, and I desire that itsscope shall be limited only by the appended claims.

1 claim as my invention:

1 1. A heating device comprising a supporting frame, a plurality of cross bars and sections of resistance ribbon supported only at their edges by, and insulated from, said bars.

2. An electric heater or resistance device comprising a substantially rectangular sup porting frame, a plurality of longitudinally erimped channel shaped cross bars that are supported at their ends by the sides of the supportingframe, and a resistance element supported by, and insulated from, the

crlmped portions of the cross bars.
