Patent ID: 7387037

Claim:
An assembly operatively cooperatable with a piston plate of a dispense head apparatus to facilitate dispensing via a set of pins temporarily mounted with respect to the assembly, the assembly comprising: a pin engagement actuation member positionable to be selectively movably engaged by the piston plate of the dispense head; a pin engagement member opposed to the pin engagement actuation member and mounted for movement with respect thereto; and a linkage coupling the pin engagement actuation member and the pin engagement member to selectively move the pin engagement member away from the pin engagement actuation member as the pin engagement member moves towards an engaged position in which a portion of the pin engagement member contacts each pin in the set of pins to apply a force thereto, and to move the pin engagement member towards the pin engagement actuation member as the pin engagement member moves toward a disengaged position spaced from the engaged position in which the portion of the pin engagement member does not contact the pins in the set of pins.
