  • Patent number: 4441706
    Abstract: An exercising machine including a vertically disposed framework defined by a pair of parallel, vertical, channel-shaped side members interconnected at their top by a top connecting member and having stabilizing supporting feet extending horizontally at their lower ends. The side members support independent slides in the form of inner channels having an inwardly extending arm and an upwardly extending peg thereon for receiving a desired number of barbell weights with a cable and pulley system being associated with the slides to enable independent vertical movement of the slides by pulling downwardly on independent handles or pulling upwardly on independent handles depending upon the manner in which the cable and pulley systems are associated. A locking bar is provided to selectively interconnect the arms on the two slides together with a central pulley system and cable system enabling the two slides and the weights thereon to be lifted by a single cable.
