Abstract
Abstract Coupling has two tubular body sections. When assembled, the sections are axially aligned, with abutting, coextensive, resilient, rubberlike gasket rings providing a rubber-to-rubber seal. The body sections have open areas completely surrounding the gasket rings to prevent fouling of the seal by accumulation of foreign material. A detachable pivot on one side of the coupling and a detachable toggle on the other side hold the body sections assembled. The coupling is disassembled and the body sections separated by releasing the toggle. The body sections are aligned, automatically, during assembly, by the pivot, which restrains relative movement in one transverse direction, and guide lugs which restrain relative movement in another transverse direction. Compression of the gasket rings and hence effectiveness of the seal, is adjusted by a threaded connection between the toggle and one of the body sections.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
259 words
A quick connect and disconnect coupling for connecting hose or the like, comprising: a pair of tubular body sections adapted to be assembled in axially aligned, confronting, end-to-end relation; each body section having an annular seat at the confronting end portion; a resilient, rubberlike gasket ring in fluid-sealing engagement with the seat on each body section, the gasket ring extending forwardly of the body section and being compressibly engageable with its counterpart on the other body section when assembled; each body section having an open area completely surrounding the gasket ring to prevent accumulation of foreign material between the gaskets when assembled; detachable pivot means between the body sections on one side of the coupling and detachable toggle means on the opposite side, the pivot means being effective when assembled to restrain relative transverse movement of the body sections in a longitudinal plane containing the pivot and toggle means; and the body sections having guide lugs each of which extends from one body section and is engageable with the other to restrain relative movement between the body sections in a direction transverse to said longitudinal plane; whereby upon relative movement of the body sections toward and away from one another, about the pivot means, the body sections are guided by the guide lugs precisely to and from an assembled position of axial alignment in which the gasket rings are compressible against one another and their respective seats by tightening the toggle means; and whereby further, the body sections may be completely disassembled and separated by releasing the toggle means.
Claim 2
Dependent Claim
259 words
A quick connect and disconnect coupling for connecting hose or the like, comprising: a pair of tubular body sections adapted to be assembled in axially aligned, confronting, end-to-end relation; each body section having an annular seat at the confronting end portion; a resilient, rubberlike gasket ring in fluid-sealing engagement with the seat on each body section, the gasket ring extending forwardly of the body section and being compressibly engageable with its counterpart on the other body section when assembled; each body section having an open area completely surrounding the gasket ring to prevent accumulation of foreign material between the gaskets when assembled; detachable pivot means between the body sections on one side of the coupling and detachable toggle means on the opposite side, the pivot means being effective when assembled to restrain relative transverse movement of the body sections in a longitudinal plane containing the pivot and toggle means; and the body sections having guide lugs each of which extends from one body section and is engageable with the other to restrain relative movement between the body sections in a direction transverse to said longitudinal plane; whereby upon relative movement of the body sections toward and away from one another, about the pivot means, the body sections are guided by the guide lugs precisely to and from an assembled position of axial alignment in which the gasket rings are compressible against one another and their respective seats by tightening the toggle means; and whereby further, the body sections may be completely disassembled and separated by releasing the toggle means.
Claim 3
Dependent Claim
44 words
A quick connect aNd disconnect coupling according to claim 1 in which the toggle means includes an adjustable threaded connection to one of the body sections, the threaded connection being adjustable to vary the compression of the gasket rings when the coupling is assembled.
Claim 4
Dependent Claim
35 words
A quick connect and disconnect coupling according to claim 1 in which the pivot means includes transverse extensions of the body sections, one having a pivot pin engageable within an open-ended slot in the other.
Claim 5
Dependent Claim
114 words
A quick connect and disconnect coupling according to claim 1 in which the toggle means includes a manually operable lever pivotably mounted on a transverse extension of one body section, an adjustment screw threadedly engaged with the other body section, the adjustment screw having a head which is adjustable lengthwise relative to the body sections, and a link having one end pivoted to an intermediate portion of the lever and having its opposite end detachably engageable with the head of the adjustment screw, the lever being movable to a stable, overcenter position to draw the body sections together and to compress the gasket rings to an extent determined by the adjustment of the screw.
Claim 6
Dependent Claim
191 words
A quick connect and disconnect coupling for connecting hose or the like, comprising: a pair of tubular body sections adapted to be assembled in axially aligned, confronting, end-to-end relation; each body section having an annular seat at its confronting end portion; a resilient, rubberlike gasket ring on the seat of each body section and being compressibly engageable with its counterpart on the other body section when the coupling is assembled; detachable pivot means between the body sections on one side of the coupling and detachable toggle means on the opposite side; the toggle means being effective to compress the gasket rings together against a common interface while pivoting the body sections about the pivot means; the pivot means being effective to restrain relative transverse movement of the body sections in one longitudinal plane containing the longitudinal axis of the coupling; and guide lugs each connected to one of the body sections and engageable with the periphery of the other body section to restrain relative transverse movement of the body sections in another longitudinal plane containing the longitudinal axis of the coupling, said planes being at substantially right angles to one another.
Claim 7
Dependent Claim
191 words
A quick connect and disconnect coupling for connecting hose or the like, comprising: a pair of tubular body sections adapted to be assembled in axially aligned, confronting, end-to-end relation; each body section having an annular seat at its confronting end portion; a resilient, rubberlike gasket ring on the seat of each body section and being compressibly engageable with its counterpart on the other body section when the coupling is assembled; detachable pivot means between the body sections on one side of the coupling and detachable toggle means on the opposite side; the toggle means being effective to compress the gasket rings together against a common interface while pivoting the body sections about the pivot means; the pivot means being effective to restrain relative transverse movement of the body sections in one longitudinal plane containing the longitudinal axis of the coupling; and guide lugs each connected to one of the body sections and engageable with the periphery of the other body section to restrain relative transverse movement of the body sections in another longitudinal plane containing the longitudinal axis of the coupling, said planes being at substantially right angles to one another.
