Abstract
22,716. Laffoon, R. F. Oct. 13. Heating by electricity. - Relates to electric blankets provided with means for varying the strength of the heating - current. A resistance wire B, preferably insulated, is arranged in a tortuous way within a fabric A, and a variable resistance is connected in series with it. This resistance consists of a number of electric lamps E mounted on a board D and wired in parallel with switches, so that any number of the lamps may be in use at a given time. The leads F<1>, F are connected to the fabric and the source of current, respectively.
