Abstract
A repeating dispenser for dispensing uniform quantities of liquid includes an actuator rotatably connected to an actuating button. The actuator is biased upward by a spring towards a downwardly facing abutment in the non-actuated condition of the dispenser and is connected through a vertically displaceable rack shaft to a slide which releaseably mounts a cylinder piston device comprising a plurality of identical pistons and cylinders. An operating rod connects the slide to a suction button which is slideable along the outside surface of the dispenser. A pawl cooperates with the rack shaft and is kept from engagement with the rack shaft in the non-actuated condition of the dispenser. The actuating button includes a series of step-like stop portions engageable with an upwardly facing abutment to allow the repeated dispensing of uniform quantities of liquid.
