US 6,269,675 B1 · Crimping tool for plastic pipe and the like

Abstract

A first jaw is rigidly mounted to a handle. A second jaw is pivotally mounted to a portion of the first jaw adjacent the portion to which the handle is secured. A spring biases second jaw member toward a closed position with respect to the first jaw. A crimping force application assembly is rotatably attached to the second jaw using a bushing which rotatably receives a second end of a longitudinally extending rod of the assembly. A second end of the rod is threadedly received in a spindle. The spindle has first and second pintles which can be seated in slots in the upper surface of the first jaw. The rod can be rotated using a manually actuated member or a second member which can be engaged by a power tool or hand tool to draw the first jaw engaged by the spindle toward the second jaw which is attached to the bushing applying a crimping force to a compression sleeve to affix it to a portion of plastic pipe.

Dependent claims

A manually operable crimping tool comprising

a) a first jaw member for engaging an element to be crimped;
b) a handle fixedly attached to said first jaw member;
c) a second jaw member for engaging the element to be crimped, said second jaw member being pivotally attached to said first jaw member for pivotal movement about a first axis;
d) a crimping-force-application assembly including
i) means to pivotally attach said assembly to one of said first and second jaw members for pivotal movement about a second axis generally parallel to said first axis;
ii) means to releasably engage another one of said first and second jaw members, said means to releasably engage being movable between a first disengaged position in which said crimping-force-application assembly is not touching said second jaw member permitting movement of said first and second jaw members onto and off of the element to be crimped and a second engaged position permitting application of a crimping force;
iii) manually operable means to reduce a distance between said means to pivotally attach said assembly and said means to releasably engage thereby causing said first and second jaw members to interact to crimp the element therebetween.
