Quick-action crimping tool

A quick-action crimping tool for crimping a crimp ring on a pipe comprising:

• (a) a first jaw means with a first portion of a crimp opening in a side thereof adjacent a second jaw means;
• (b) a second jaw means with a second portion of a crimp opening in a side thereof adjacent the first jaw means, said second jaw means having a concave surface on a side thereof opposite the second crimp portion;
• (c) a jaw constraint lever arm means having a first end and second handle end, the first jaw means being rigidly connected to the first end of the jaw constraint lever arm means, the second jaw means being pivotally connected at a first pivot point to the jaw constraint lever arm means adjacent the first jaw means so that the second jaw means can pivot about the first pivot point and thereby open and close relative to the first jaw means;
• and
• (c) a leverage arm means having a first end and a second handle end, said leverage arm means being pivotally connected to the jaw constraint lever arm means at a second point spaced from the first pivot point, the first end of the leverage arm means bearing in slidable engagement with the concave surface of the second jaw means, the concave surface being oriented so that during pivotal movement of the leverage arm means about the second pivot point relative to the jaw constraint lever arm means reciprocally moves the second jaw means into a closed position relative to the first jaw means when the leverage arm means is spaced furthest apart from said jaw constraint lever arm means.
