WILLIAM S. HADAVAY, J R., OF EAST ORANGE, NEW JERSEY, ASSIGNOR T WESTING- HOUSE ELECTRIC & MANUFACTURING COMPANY, A CORPORATION OF PENNSYL- VANIA.
To all whom it may concern) Be it known that I, WILLIAM S. HAD.- AWAY, Jr., a citizen of the United States, and a resident of East Orange, in the county of Essex and State ofNew. Jersey, have invented a new and useful- Improvement in Resistance or Heating Elements, of which the following is a specification.
My invention relates to electric resistance or heater elements, and it has for its object to provide a simple and durable element or unit of this class that shall have a relatively high resistance and, at the same time, be rigid and self supporting. v
Strips or ribbons of steel, or other suitable resistance material, having a plurality of lateral slots to provide zig-zag paths forupon itself and by providing suitably located portions of greater width without slots, the edges of which may be folded over the slotted portions of the ribbon, thereby forming a rigid unit. A single ribbon may obviously be utilized for producing a series of units, so that no additional connections between units shall be required.
Figure 1 of the accompanying drawings is a plan view of a portion of aresistance strip or ribbo n which is suitable for producing the unit of my invention. Fig. 2 is a plan view of an insulating strip which is used iii connection with the resistance strip of Fig. 1, and Fig. 3 is a perspective view of a series of units constructed in accordance with. iny invention- Fig. 4 is a perspective. view of a single unit, on a larger scale, and Fig. 5 is an outlineof. a set of electrically heated laundry rolls that serve to illustrate.

of cast grid resistance unit.
Referring to Figs. 1, 2, 3 and 4, a resistance strip or ribbon 1 is provided with a; plurality of lateral slots 2 and 3 out alternately from opposite edges to provide a zigzag path for the electric current, said slots beiiig'arranged in groups such as 4, 5 and 6 which are. separated by lengths of uns'lotted ribbon 7, 8 and 9. tions are materially wider tl a portions of the ribbon, in order to provide flanges or edges 10 which may be folded over the narrower parts, as hereinafter described. The ribbon is formed into a series of rigid resistance units by folding back the slotted portions on-tlie unslotted portions and folding over the flanges or projections 10 to hold the ribbon, which has assumed a zig-zag form, in position. For example, if the strip or ribbon shown in Fig. 1 is considered, the
portion 4 may be folded backiipon the poriion 7 and the flanges 10 of the portion 7 finally folded over the edges. of the outermost layer, which preferably constitutes one-half of the portion 8. The portion 5 and the other half of the portion 8 are similarly folded on to the portion 9, the flanges of which are bent in a similar manner. By this means, a series of units 1], such as is shown in Fig. 3, is produced. Before the ribbon is folded back upon itself, it is, of.
course, insulated by some suitable means, such as the ribbon or strip of Fig. 2. The relative position of the insulating strips and the conducting ribbon is clearly shown in Fig. 4.
The resistance units may be utilized for various purposes, of which the set of laundry rolls of Fig. 5 constitutes an illustration. In this figure, a plurality of units are wound in the form of a helix 12 within each of the rolls 13 and may be held in position by any suitable means. I
Referring to Figs. 6 a nd 7 of the drawings, the resistance unit 15 here shown is formed by folding back the unslotted end 16 of the punching or stamping of Fig. 7 and bending the flanges or projections 17 over the zig-zag grid portion 18, after suitable heat-resisting insulation 19 has been interposed between the two pints of the unit, as shown in Fig. 6. This resistance unit is Alternate unslotted porn the other railway service.
I venient intervals, and insulating strips being a series of slotted sections separated specially rigid and at the same time may be of relatively high resistan e, and inexpensive to manufacture.
The form may he modified so that the projections 20 which form the terminals and the points of supportf the device, correspond to any iv'ell known formof cast metal resistance grid. By this means, the stam-ped unit may replace the fragile highrcsistance cast grids in the assembled frames or boxes which are so generally employed in electric It is evident that variations in the size and arrangement of parts may be effected in the structure illustrated without departing-from the spirit of my invention.
I claim as my invention:
1. A resistance strip or ribbon comprising sections of different widths folded upon each other and having the edges of the Wider sections bent over the d es of the contigu ous narrower-section's.
2.. A resistance or heater unit comprising a single folded resistance strip or ribbon having relatively wide short sections at 0011-,
tween which the resistance ribbon is assembled, the edges of said wide sections being bent over the edges :of the intermediate. folded section's.
.3; k resistance or heater-unit comprising a single -folded resistance strip or ribbon having short sections ofrelatively great rigidity which are secured to the adjacent folded portions.
4. A res1stance or heater unit comprising a continuous resistance strip or ribbon hay-- '5 sections of greater rigidity, said slotted secsa-id strip and said grid and having its edges bent over the edges of the grid. 1
7..-A resistance ribbon comprising slotted 4 and unslotted sections of a given width and of different lengths and unslotted sections of greater widtlnsaid' slotted sections being folded upon themselves andsaid ivider unslotted sections being folded upon the adjacent slotted section folds and attached. thereto by bent over edges.
S. A resistance unit consisting of'resistance material and a ribbon comprising relatively longslotted sections folded upon themselves, relatively short tmslotted con- 'necting sections ,and relatively, wide' unslotted sections-4 folded against the slotted 7 section; folds and secured thereto by. bent- ,over'edges.
