A power operated chair having a base frame assembly, a chair assembly mounted on the base frame assembly, and an internal combustion engine mounted on the base frame assembly. A fuel tank is mounted on the back of the chair assembly. One or two rear drive wheels are rotatably mounted on a transversely extending rear axle that is supported from the base frame assembly. If one wheel is utilized it would be centrally positioned along the length of the rear axle and if two drive wheels are used they would be centrally placed along the length of the rear axle and close enough to each other so that a differential gear assembly would not be necessary between them. A pair of laterally spaced steerable front wheels are mounted to the forward end of the base frame assembly and a pair of laterally spaced rear wheels that are non-steerable are mounted to the rearward end of the base frame assembly. There is also a drive system connecting the internal combustion engine to the rear drive wheel. The drive wheel has a bottom surface spaced vertically lower than the bottom surface of each of the laterally spaced rear wheels so that when the power operated chair is oriented in a level state, the laterally spaced wheels do not touch the ground.

Power operated chair

A C-shaped or ring-shaped collar member having a groove along the inner periphery of one end in combination with an adjustable pin insert for engaging the end of a torsion spring threaded on a cone. Apertures are provided in the collar for accepting a winding bar to rotate the collar.
