Abstract
346,085. Variable resistances. THOMAS, J. E., 63, Rue Edgar-Quinet, Malakoff, Seine, France. Feb. 7, 1930, No. 4188. Convention date, Oct. 22, 1929. [Class 37.] A contact element for a rheostat &c. consists of an elastic ring opposite points on the outside of which press against the operating spindle or a member attached thereto and the resistances element, on which the ring rolls as the spindle is turned. In the arrangement shown the ring 12 is placed between the spindle 3 and the resistance element 1 and is caused to roll on the resistance element by rotating the spindle. A plate 13 on the spindle retains the ring 12 in place and a forked piece 6 mounted on a sleeve 5 surrounding the spindle 3 engages the ring 12 and is rotated thereby so as to operate a pointer 8 attached to the sleeve 5. A flexible band of metal may be interposed between the resistance element 1 and the ring 12, which may then be of insulating materials.
