Pneumatic exercising device

A pneumatic exercise device comprising:

• a. a frame having a base supporting an upright elongate hollow support member which support member has therein an integral airtight accumulator of fixed capacity;
• b. an external bracket supported by said support member and being adjustable in position along the length thereof;
• c. a lever arm pivotally mounted to said bracket for rotation thereabout in a plane of the longitudinal axis of said support member, one end of said lever having means to be grasped by the user of said device;
• d. a pneumatic cylinder including a piston and piston rod, one end of which cylinder is pivotally mounted to said lever arm and acts thereagainst, the capacity of said pneumatic cylinder being less than 1/30th of the capacity of said airtight accumulator;
• e. a length of flexible conduit connecting the compression slide of said pneumatic cylinder with said accumulator;
• and
• f. a pump adapted to compress and admit ambient air to said accumulator and permitting the pressure in such accumulator to be controllably increased.
