Abstract: An exercise machine in the nature of a stationary cycle exerciser. The exercise machine replaces the conventional crank-arm rotary pedal drive with reciprocating treadles or pedals connected to drive a work-utilizing device at a substantially uniform rate throughout the entire input stroke by the user. Hand-operated levers are also provided for manipulation by the user, and movement of these levers is coupled to the working load.

The hand levers are operatively interconnected to the treadles for simultaneous movement.

Abstract: An improved shuttle returner for use in projectile looms. The shuttle returner comprises a relatively inelastic member for receiving the impact of an arriving shuttle, and a relatively elastic member coupled to the receiving member for absorbing the shuttle impact. The receiving member and elastic body member are joined together along mutually confronting surfaces substantially perpendicular to the line of impact, maximizing transfer of force into the body member without transmitting substantial impact through the elements interconnecting the receiving member and body member.
