Abstract: A quick-connect fitting assembly is disclosed for releasably connecting a pair of fluid conduits in fluid communication with one another. A socket portion on one of the fluid conduits is adapted for receiving the other fluid conduit inserted longitudinally into the socket portion. A laterally-extending protuberance on the inserted fluid conduit is longitudinally restrained by a retaining assembly generally adjacent the fluid socket, with the retaining assembly including one or more resilient spring of barb members longitudinally interlocked with the inserted fluid conduit. A pair of collar members are longitudinally interconnectable with one another, either by a threaded engagement or by a "bayonet-type" engagement, to releasably restrain the assembly in a connected condition.

Abstract: A quick-connect fitting or coupling assembly is adapted for releasably connecting and disconnecting a pair of fluid conduits in fluid communication with one another. The assembly includes a socket on one of the fluid conduits for receiving the other fluid conduit inserted longitudinally therein into an interlocking engagement with a resilient barb or finger member on a retainer member disposed within the socket. A removal member is selectively slidably movable in the socket for deflecting the barb or finger member out of such interlocking engagement in order to remove the previously inserted fluid conduit. The assembly also preferably includes lateral support members for laterally supporting the fluid conduits relative to one another and thus strengthening the connection therebetween. The preferred embodiment includes a feature by which the fitting assembly is relatively tamper-resistant.

Abstract: A two stage vacuum break or fluid motor device of the type used to control choke valves of internal combustion engine carburators. The motor uses a single diaphragm in which the fluid motor plunger operates in a first stage in response to movement of a portion of the diaphragm and in a second stage in response to movement of the entire diaphragm. The stages of movement are under the control of separate sources of manifold pressure which may be made available to the device independently of each other. The two stages of operation may be used to control one or more choke valves through a single output plunger or to control a pair of output plungers movable independently of each other.

Abstract: A method of forming a cup shaped housing member with an integral inlet tube extending radially to the axis of a cup shaped member from a flat strip of metallic material in progressive dies such that a tube is formed first to extend parallel to the axis of the cup shaped member and in subsequent progressive steps is moved first to a position extending at an angle to the axis and finally to a position extending radially to the axis of the cup shaped member. SUThis invention relates to a method and apparatus for forming metal parts in progressive dies and more particularly it relates to the method and apparatus of forming a dished housing member with a tube extending radially from the axis of the housing member.To provide a radially extending tube from a housing usually requires the welding of separate parts together or requires forming the assembly from molded materials such as plastic.

Abstract: A method and apparatus for making a housing member with a projecting bracket receiving adaptor from a sheet of flat material in which the material is formed in progressive dies by displacing material in the direction of die movement and also transversely thereof by a die arrangement movable into engagement with a portion of the material displaced in the direction of die movement to confine that portion while permitting displacement of the unconfined portion transversely.
