  • Shuttle returner and improved body therefor
    Patent number: 4880037
    Abstract: An improved body member for a shuttle returner used in a projectile loom. Embedded within the relatively elastic body member is a relatively inelastic reinforcing element which takes up tensile force applied to the body member, thereby strengthening the body member. The reinforcing element is substantially flexible in response to compressive force applied to the body member, so that the elasticity of the body member in compression is not reduced by inclusion of the reinforcing element.

  • Exercise machine
    Patent number: 4842268
    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.

  • Shuttle returner apparatus
    Patent number: 4757843
    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.
