Abstract: A hysteresis brake assembly comprising a fan member, a vaned heat dissipating cover member, a pair of pole members, a pair of hub members and a disc shaped ferro-magnetic brake member. The fan propells air through holes provided in the cover and one pole member and the air is directed by vanes on a first hub member to flow (1) in part over one side of the brake disc and (2) in part through holes in the brake disc to the other side of the brake disc, where a second vaned hub directs the air over the other side of the brake disc; thereby cooling the brake disc on both sides. After cooling the brake disc, the air is forced outward from the brake assembly through escape holes provided in the cover member and one pole member.

Abstract: A power driven transmission assembly for an internal combustion engine, which assembly includes an endless V-belt that extends between a driving and a driven pulley. The driven pulley is subject to varying loads. The driving and driven pulleys each include first half portions which are transversely movable relative to the second half portions. By concurrently moving the second half portions relative to the first half portions, the effective pitch diameters of the driving and driven pulleys relative to the belt is varied for the transmission assembly to automatically deliver rotational power that in magnitude is related to a desired degree to the torque curve or torque capability of the prime mover with which the invention is associated. The effective pitch diameter ratio of the pulley system is changed by varying the pitch diameter of the driving pulley by power means.
