Abstract: A constant mesh gear driven continuously variable transmission including a minimum of two cones in mesh with either an axial sliding ring gear or an axial sliding circular gear. The cones and ring gear or circular gear are enclosed in a housing. An input shaft is journaled in the housing. The cones rotate about their own axes and revolve about the shaft in some embodiments. The ring gear or axial sliding circular gear is slidable axially relative to the cone gear, and the output gear ratio is varied by the axial position on the ring gear or sliding circular gear.

Abstract: A gear driven continuously variable transmission including an epicyclic cone in mesh with an axially slidable nonrotating ring gear. The cone and ring gear are enclosed in a housing. An input shaft is journaled in the housing. The cone revolves about the axis of the shaft as it rotates on its own axis and is connected to the shaft to convert axial rotation of the input shaft into rotation of an output gear. The ring gear is slidable axially relative to the shaft, and the output gear ratio is varied by the axial position of the slidable ring gear.

Abstract: A self-adjusting, mechanically actuated disc brake assembly in which the brake pads are pressed against the brake disc by cooperating drive threads formed on an actuating shaft and a piston. Adjustment is obtained by an adjuster nut having a fine thread complementary to and in engagement with a fine thread formed on the actuating shaft and a ratchet mechanism, including cooperating inclined teeth and spring loaded pins carried by the adjuster nut and an opposing portion of the piston. The frictional forces between the nut and the shaft are greater than those generated by contact between the nut and other portions of the assembly so that the nut tends to rotate in unison with the shaft.
