ABSTRACT:
A coin-operated apparatus for dispensing a predetermined volume of a fluid to be purchased by insertion of a coin into a slot, includes a plunger for forcing the coin between two slides, one of which is moved by the coin to a fluid pumping position and the other of which is moved by a piston after the predetermined volume of fluid has been pumped, to a coin release position. Upon coin release, the fluid pumping is discontinued and the piston moves back to dispense the purchased fluid, whereupon the parts return to their initial position. The two slides move at right angles to each other.
