Abstract
792,062. Variable resistances. GENERAL MOTORS CORPORATION. Sept. 20, 1955 [Sept. 22, 1954], No. 26842/55. Class 37. [Also in Group XXXVII] A rheostat combined with a switch (see Group XXXVII) comprises a spring contact 97 having a crescent-shaped slot 116 and mounted on a bush 100 rotatable with a shaft 77 within the insulating rheostat body 30. The outer contact rim 114 rides over the resistance wire coil 96 received in a groove 29 in the body 30, whilst the inner part 122 of the contact rides over an annular contact 120. A tongue 31 of the body 30 extends through an aperture 33 in a mounting bracket 18.
