Abstract
A leverage device includes elongated body connected to a pivoting base, and a means for attaching the elongated body to the “T” handle of a pump used in filling air tanks. In use one securely connects the pivoting base to a stationary vertical surface, connects the attachment assembly to a pump, and repeatedly moves the elongated body in an up-and-down motion. This action moves the attached pump's “T” handle, thereby causing the pump's piston to move with decreased effort and increased speed over the conventional motion of pumping. In this manner a compressed air tank can be filled to approximately 3,000 psi using human power only.
Claims17
A leverage device including:
- A. An elongated body having a proximal end, a distal end, and mid-body portion there between;
- B. A mounting assembly connected to said proximal end;
- C. A grip engaged with said distal end;
- and
- D. An attachment assembly connected to said mid-body portion.
A compressed air tank filling system including:
- A. An air pump having a T-shaped handle;
- and
- B. A leverage device releasably engaged with said T-shaped handle.
A method for filling an air tank with compressed air including the steps of:
- A. Connecting an air tank to an air pump having a T-shaped handle;
- B. Engaging said T-shaped handle with a leverage device having an elongated body;
- and
- C. Pumping the distal end of said elongated body to effectuate corresponding movement of said T-shaped handle, said pumping performed manually by a human.
