Abstract: Retaining clips are provided by the present invention for use in a novel method of constructing radiant heat flooring. The clips are used to secure heating pipe that has been laid on top of a wire grid. The pipe is secured by attaching the retaining clip to the wire grid so that the retaining clip passes from one point of attachment on the wire grid, over the pipe, to another point of attachment on the grid, without passing beneath the grid or the pipe.

Abstract: This invention is directed to a novel quick action crimping tool. More particularly, this invention pertains to a novel high leverage tool which can be used to crimp metal rings onto piping joints. A quick-action crimping tool comprising: (a) a first jaw means with a portion of a crimp opening in a side thereof adjacent a second jaw means; (b) a second jaw means with a portion of a crimp opening in a side thereof adjacent the first jaw means; (c) a jaw constraint arm means, the first jaw means being rigidly connected to the jaw constraint arm means, the second jaw being pivotally connected to the jaw constraint arm means; and (d) a leverage arm means pivotally connected to the jaw constraint arm means and during pivotal movement relative to the jaw constraint arm means reciprocally moves the second jaw means between an open position and a closed position relative to the first jaw means.

Abstract: This invention is directed to a novel pipe ring crimping tool which is adapted for crimping a ring over plastic plumbing pipe onto a plastic fitting.
