Benefits of technology

[0007]A crimping tool for pipe fittings has a pair of semi-cylindrical opposing jaws with opposing ends, pivotally attached at one end of each, for closing and opening movement about the pivot axis. When closed, the jaws define a cylinder for engaging a pipe or other cylindrical element to be crimped. The other ends of the jaws have integral extensions that meet when the jaws are closed and are clamped together by a si

Problems solved by technology

However, its size, which is slightly larger than a battery-powered hand-held electric drill, prevents its use in very small spaces.
However the arrangement of parts with a handle adjacent the pivoting connection of the jaws and the complicated crimping-force-application assembly make the invention bulky, awkward to use, and complicated and expensive to manufacture.

Embodiment Construction

[0012]Referring to FIG. 2, a T-shaped, hollow ProPress® T-shaped pipe fitting 30 of the type made by the Rigid Tool Company is shown with circumferential ribs 32 spaced near each end 31 of the connector 30. Each rib covers a sealing 0-ring of high-performance elastomer, not shown. When crimped with an appropriate tool, the fitting, copper tubing and sealing ring are combined to form a permanent watertight seal. The ProPress® high-performance fittings are more particularly described and depicted at www.propresssystem.com / and www.ridgid.com / propresssystem / ppfittings.asp.

[0013]Referring now to FIGS. 1 and 3, the present invention 10 comprises a first semicircular jaw 12 opposing and pivotably attached to a second semicircular jaw 16 by first pin 20. Jaw extensions 14 and 18 are integral and extend from jaws 12 and 16 at their free unattached ends. Optimally the jaws and jaw extensions are made of rigid, heavy-weight, tempered metal. Jaw extensions 14 and 18 have slots 22 and 24 at the...

Abstract

A crimping tool for pipe fittings has a pair of semi-cylindrical opposing jaws with opposing ends, pivotally attached at one end of each, for closing and opening movement about the pivot axis. When closed, the jaws define a cylinder for engaging a pipe or other cylindrical element to be crimped. The other ends of the jaws have integral extensions that meet when the jaws are closed and are clamped together by a simple crimping force assembly comprising a threaded eyebolt, the eye end being pivotally attached to the end of one jaw extension. The bolt swivels in and out of a slot in the other jaw extension. A nut on the other end of the eyebolt is used to compress the two jaw extensions together. In another embodiment, the jaws have annular grooves on their inner surfaces to accommodate the male ridges of ProPress® pipe fittings.

Description

[0001]This invention claims the benefit of the inventor's previously filed provisional application, No. 60 / 699433.BACKGROUND OF THE INVENTION[0002]This invention is directed to apparatus for crimping and sealing copper fittings joining copper pipe, more particularly for crimping ProPress® fittings.[0003]The need for leakproof conduit for fluids is extensive and entails the use of variously shaped connectors and pipe fittings for routing the conduit. Copper tubing and fittings were traditionally connected by “sweating ” the joints, or with threaded connectors. Then polyvinyl choride (PVC) conduit became widely used, particularly in residential plumbing applications. Sections of PVC were glued together. Later technology substituted flexible PVC and utilized a crimp ring to compress the tubing ends deformably down against a rigid insert positioned in the internal conduit in the tubes. This use of crimp rings is particularly well known in association with elastomeric hose or tubing, whe...
