  • Accessory apparatus for weight lifting
    Patent number: 4253662
    Abstract: Accessory apparatus for use by a person working with weights in a body building program. Under a modern, well accepted theory muscle growth and strength can best be promoted by "high intensity" exercise which means the repetitive performance of a resistance movement to the point of momentary muscular failure. In performing a high intensity exercise, as for example in bench pressing, the exerciser may find himself trapped beneath a heavy weight upon reaching the point of muscular failure. In such case, the apparatus of the invention eliminates the need for a human partner by providing power driven mechanical device for lifting the weight, said mechanical device being put into operation by a hand or foot operated switch easily accessible to the exerciser.

  • Railway car wheelset and rails therefore
    Patent number: 4230043
    Abstract: An improved railway car wheelset having a novel wheel configuration that permits greatly improved performance on existing and improved track. This means that substantially higher rolling speeds can be achieved without loss of stability and while maintaining the ability of the wheelset to self center and self steer. The improved performance is enabled primarily by forming the track engaging surface of each wheel of the wheelset with an outward arcuate projection also referred to herein as the convex annular portion of the wheel. This wheel configuration operates to reduce the magnitude of the effects that occur when disturbances cause the wheelset to deviate from centered position on the track.
