RESISTANCE umr.
.for electric circuits and has for its object the of wire in t provision of a device of this character which can be made at a very low cost, is adapted to a variety of uses, and is at the same time .thoroughly eflicient, safe and durable.
In carrying out my invention 1 provide a sheet of insulating material, having secured thereto a resistance conductor. Resistance units have heretofore been made of a sheet of insulating material having resistance conductors secured to the surface of or within the sheet, but they have been open the size of resistit has facture or are limited as to ance wire to be used. For instance,
been suggested that the resistance wire be sewed into the resistance sheet; For very small sizes of wire this might be satisfactory but it is impracticable to use the larger sizes is way. Iovercome this objection by securing the resistance conductor to the sheet byjected through the sheet and fastened by some means, as for instance, by bending the back onto the sheet.
1001:? the accompanying drawings, in which I device e a stiffer and have shown one embodiment of my invention, Figire 1 represents a plan view of my ig. 2 is anend view; and Fig. 3 is a rear view of the same.
Referring to the drawings, 10 is a' sheet or block of insulating material, the particular nature of which is not essential to my invention. The sheet may be flexible and comosed of asbestos, fiber or the like, or it may more rigid material, such as porcelain or the like. The material will depend to acertain extent upon the particular use to which the device is to be put, upon the size and the fineness of the resistance wire to be mounted thereon. A resistance conductor 11 is secured to this sheet at intervals by Specification of Letters Patent. Application filed September 22. 1906. Serial No. 335,696.
to obj ection that they are either expensive to manumeans of loops which are pro- Patented May 14, 1907.
1 means of 100 s 12 which are projected through the hol es 13. The particular method of performing this operation is no part of my invention. The sheet may be previously perforated, and theloops forced through or in a case of'fiexible and .easily worked material, the loops may be'forced through the material by means of a punch or other appro priate implement. These loops are secured in place in any desired manner, as by bending them back onto the sheet as shown at .12.
Any desired arrangement of the conductor on the sheet may be made and many other changes. will suggest themselves to those skilled in the art without departing from the spirit of my invention, sco e of which is set forth in the claims annexe hereto.
. What by Letters Patent of the United States, is,
1. A resistance unit comprising a sheet of ductor mounted thereon and secured at intervals by projecting loops into thesheet.
2. A resistance unit comprising a sheet of insulating material and a resistance 'conductor mounted thereon and secured to the sheet by projecting loops therethrough at intervals.
'3. A resistance unit comprising a sheet of insulating material and a resistance conductor mounted thereon and having loops 5. A resistance unit comprising a sheet of insulating material having a resistance conby projecting loops through the sheet and bending the conductor to prevent its return.
In witness whereof, I have hereunto set my hand this twentieth day of September,
