ABSTRACT:
A pick up device having an elongated tubular member whose opposite ends are attached respectively to a handgrip assembly and a dual jaw member gripping assembly. The handgrip assembly has a trigger which is attached to a rod member that passes through the interior of the elongated tubular member and which has its opposite ends attached to the dual jaw member gripping assembly. The dual jaw member gripping assembly has a pair of elongated jaw members each having a front leg portion, a rear leg portion, and a pivot pin aperture intermediate the front and rear leg portions. It also has a top plate and a bottom plate. The bottom plate has an upstanding hub formed at the opposite corners of its front portion. The jaw members fit over the hubs and are held in place by self-tapping screws which thread into the hubs extending upwardly from the bottom plate. Shoulders on the hubs position the top plate at the correct spacing from the bottom plate. The dual jaw member gripping assembly further has a clevis with vertically spaced top and bottom walls interconnected at their forward end by a pressure wall. The rear leg portions of the respective jaw members are captured within the clevis and as the clevis is drawn rearwardly by the rod member connected to the trigger, the pressure wall draws against the tips of the jaw members causing them to pivot toward each other as the clevis travels rearwardly. As the trigger is released, a spring located in back of the clevis pushes it forwardly causing the jaw members to pivot away from each other at the point of contact with the axial travel stop member.
