    • 22,772. Gardner, E. Nov. 19. Auxiliary actuating- gear; cam - actuated pumps; eccentric - actuated pumps; leveractuated pumps; spring- actuated pumps; stroke, varying.-A fuel pump for internal-combustion engines comprises means giving a reciprocating motion of constant length and duration, and, between such means and the pump plunger, a yielding device for transmitting motion between these parts, and governorcontrolled means for arresting the motion of the yielding device. In one form an eccentric sleeve c has secured in it one end of a sleeve d enclosing springs e, and an adjustable plunger i for transmitting the motion of the sleeve c to the springs. The springs transmit their motion to the pump ram b by means of a plunger f, the stroke of which is controlled by a wedge g under governor control, whereby the length and duration of the stroke of the ram b is controlled. An arm m is provided for hand actuation. In a modification, the eccentric a is replaced by a cam, and the sleeve c by a sliding member carrying the plunger i. In another form, a cam actuates a lever in contact with a member carrying the plunger i. The springs also act as a safety device.
