Abstract
Abstract A fluid conveying connection coupling comprising two identical couplings which, when connected to the end of two fluid conveying flexible lines, can be leaklessly attached to each other to join the lines and simultaneously therewith, permit flow of fluid therein and self-sealingly interrupt the flow upon disconnecting the couplings.

Claim 1
Independent Claim
352 words
In fluid conveying couplings of the type disclosed comprising: a pair of identical coupling means each consisting of, a housing member; an end member adapted to be rotatably disposed within one end of said housing member; said end member having a threaded opening in one end to receive a conduit; a threaded opening at the other end of said end member adapted to receive and support a valve means within said housing; fluid conveying ports disposed within said valve means, spring means adapted to urge said valve means to its closed position; a clutch member rotatably interposed between said housing member and said valve means and axially retained in said housing member by said valve means and said end member; said clutch member including a plurality of fingers, including teeth; said housing member including a plurality of teeth adapted to engage said teeth of said clutch member upon connecting said coupling means; said clutch member being adapted to cooperate with said housing member in such manner as to predeterminately limit rotary movement of said housing member relative to said clutch member, whereby, when said identical coupling means are brought into connecting relation, said clutch allows said limited rotary movement of said housing member to effect interlocking of said teeth of said clutch member and said teeth of said housing member to prevent axial disengagement of said identical coupling means; said connecting of said coupling means simultaneously activating said valve means allowing said fluid ports in said valve to open for passage of fluid therethrough; said housing member including retaining means adapted to cooperate with said clutch member and said end member to axially retain said last-mentioned two members within said housing member, whereby; said coupling means as connected by said clutch member and said housing member tend to pull each coupling means toward the other by action of said spring means augmented by fluid pressure internal of said coupling means, and whereby; and increasing of internal fluid pressure increases the sealing effect at the abutting faces of said housing member of said coupling means to prevent fluid leakage at said abutting faces.
Claim 2
Dependent Claim
352 words
In fluid conveying couplings of the type disclosed comprising: a pair of identical coupling means each consisting of, a housing member; an end member adapted to be rotatably disposed within one end of said housing member; said end member having a threaded opening in one end to receive a conduit; a threaded opening at the other end of said end member adapted to receive and support a valve means within said housing; fluid conveying ports disposed within said valve means, spring means adapted to urge said valve means to its closed position; a clutch member rotatably interposed between said housing member and said valve means and axially retained in said housing member by said valve means and said end member; said clutch member including a plurality of fingers, including teeth; said housing member including a plurality of teeth adapted to engage said teeth of said clutch member upon connecting said coupling means; said clutch member being adapted to cooperate with said housing member in such manner as to predeterminately limit rotary movement of said housing member relative to said clutch member, whereby, when said identical coupling means are brought into connecting relation, said clutch allows said limited rotary movement of said housing member to effect interlocking of said teeth of said clutch member and said teeth of said housing member to prevent axial disengagement of said identical coupling means; said connecting of said coupling means simultaneously activating said valve means allowing said fluid ports in said valve to open for passage of fluid therethrough; said housing member including retaining means adapted to cooperate with said clutch member and said end member to axially retain said last-mentioned two members within said housing member, whereby; said coupling means as connected by said clutch member and said housing member tend to pull each coupling means toward the other by action of said spring means augmented by fluid pressure internal of said coupling means, and whereby; and increasing of internal fluid pressure increases the sealing effect at the abutting faces of said housing member of said coupling means to prevent fluid leakage at said abutting faces.
Claim 3
Dependent Claim
61 words
A fluid coupling as set forth in claim 1, wherein: said valve means comprIses a valve body member; a movable valve member including said flow ports; and said spring means partially surrounding said movable valve member and adapted to move said movable valve member axially within said body member to close said fluid ports once said coupling means have been disconnected.
Claim 4
Dependent Claim
140 words
A fluid coupling as set forth in claim 1, wherein: said coupling means are provided with a plurality of knobs angularly disposed upon said housing member to facilitate hand rotation of said housing member during said connecting of said coupling means; said housing member being rotatable relative to said clutch member within limits determined by a rotary indexing means operably disposed in said housing member and said clutch member so that during said connecting of said coupling means, rotation of said housing; member of a first coupling means to its locked position, as determined by said indexing means, and rotation of said housing member of said second coupling means to the locked position thereof; and said knobs of said first and said second coupling means said housing members become axially aligned to indicate that both coupling means are completely interlocked.
Claim 5
Dependent Claim
27 words
A fluid coupling as set forth in claim 1, wherein: said clutch member and said housing member are adapted to be rotated independently of said each member.
Claim 6
Dependent Claim
91 words
A fluid coupling as set forth in claim 1, wherein; said clutch member is of such axial length as to cooperate with a pilot means disposed within said clutch member when said coupling means are disconnected; whereby said clutch member said fingers of one coupling means can be axially meshed with said clutch fingers of said second coupling means during the start of connecting said couplings; and said fingers being piloted onto said pilot means to centralize said first coupling relative to said second coupling and thereby facilitate connecting said couplings.
