ABSTRACT:
A dispensing pump including a double trigger mechanism for actuating a reciprocal plunger having a through passage for communication with the pump at one end and a nozzle at the other end. The trigger mechanism includes a body portion and structure on the body portion for pivotally mounting the trigger on the plunger. A pair of angularly spaced handles extend from the body portion and extend from the plunger and pump to permit the grasping thereof. The trigger mechanism is interengaged with the plunger so that movement of either handle or in a further embodiment both handles will pivot the body portion and move the plunger in one direction and release of the handle will permit the plunger to reciprocate to the original position by pivoting the body portion and handle to the original position.
