Abstract
Abstract A releasable connector for various conduits utilizing a canted locking ring and is provided with canting means in the form of a projection from the locking ring having an aligning finger and intermediate abutting shoulder. A releasable pin assembly is incorporated with a boss or groove on the outside of the housing of the connector to permit release of the locking ring from the conduit. A jamming screw may be used to add additional pressure to cant the locking ring for holding a conduit. The releasable connector may be extensible by use of telescopic parts to repair various lengths of pipe. A funnel shaped skirt may be secured to the releasable connector to guide the connector to cap wild wells.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
203 words
A releasable connector for pipes, tubes and like conduits comprising: a. a housing having a central bore sized to receive said conduit, 1. means positioned in said sized central bore for sealing said conduit to effect a watertight seal, b. an enlarged bore positioned adjacent the mouth of said central bore, c. a spring sized to fit within said enlarged bore and freely receive said conduit, d. a locking ring biased against said spring to a canted position for grasping and holding the outer surface of said conduit, e. canting means on the opposite side of said ring for canting said locking ring to hold said conduit in position, f. abutment means at one end of said enlarged bore to limit movement of said canting means, g. support means on the exterior of said housing to position a release pin for contact with said locking ring and to permit axial alignment of said locking ring with said conduit for release of said conduit, h. release pin actuating means pivotally and releasably connectable to said support means, and i. a release pin pivotally connected to sAid release pin actuating means to effect release of said conduit by substantially axial movement of said release pin.
