Abstract The apparatus described is a make-and-break joint connection for a conduit of a pressure-fluid-supply line. The apparatus includes a relatively fixed tubular socket having a tubular plunger reciprocable therein and protruding from one end thereof. A flexible fluid-supply conduit is connected with the plunger and communicates with a fluid passageway extending longitudinally through the plunger. Spring means are disposed within the socket to provide a floating mounting for the plunger so that it is capable of being tilted angularly and moved horizontally relative to the socket. The apparatus further includes a cup movable toward and from the protruding end of the plunger for telescoping engagement therewith. A fluid tube is provided through the bottom of the cup for connection with a fluid conduit leading to an operating pressure cylinder A coupling on the protruding end of the plunger is adapted to engage a coupling on the inner end of the fluid tube in the cup to create an unobstructed fluid passageway between the two conduits when the cup is telescoped onto the protruding end of the plunger. The apparatus is particularly suitable where it is desired to utilize a make-andbreak connection which is self-aligning and speedy in operation.
A make-and-break joint for a conduit comprising conduit means, a relatively fixed tubular socket, a tubular plunger reciprocable in said socket and protruding from one end thereof, said plunger having a loose fit in said socket permitting limited angular relation therebetween, sprIng means urging said plunger toward said one end of said socket, a cup movable toward and from the protruding end of said plunger for telescoping engagement therewith, the interior of said cup making a snug fit with the exterior of said protruding end when telescoped therewith, a portion of said conduit means fixed to and projecting inwardly of said cup, a first coupling fitting disposed on the projecting end of said conduit means portion in said cup, a passageway means formed in the protruding end of said plunger, a second coupling fitting disposed on said protruding end of said plunger in communication with said passageway means, and said second coupling fitting adapted to engage said first coupling fitting when said cup is in engagement with the protruding end of said plunger.
