Patent number: 4549457Abstract: A compact apparatus for applying equal force to opposite sides of a workpiece including an arm mounted on a frame for movement in a plane to be rotated into alignment with the workpiece. The arm is moveably connected to the frame and is guided into position to engage the workpiece by tracks and followers. The workpiece is engaged on opposite sides by a tool and an anvil which perform an operation thereon. The forces applied by the tool and the anvil are equalized by a pivotable member to prevent distortion of the workpiece while performing the operation. The pivotable member engages a biasing spring which is connected to the frame on its lower end and engages the arm on its upper end to urge the arm in one direction relative to the frame.Type: GrantFiled: April 25, 1983Date of Patent: October 29, 1985Assignee: West Industries, Inc.Inventors: Alf L.

Patent number: 4506862Abstract: A fluid hose connector capable of resisting transverse forces to avoid inadvertent disconnection from a mating connector includes an elongated hollow body which includes a first portion that provides an extending collar to restrain the lateral movement of a mating connector and a second portion which provides for connection to a source of fluid. The body portion includes a hollow coupling for removably retaining a mating connector and a hollow plunger which is adapted to be slidably received within the coupling. The plunger is provided with a first disconnect position which prevents fluid flow through the body and a second position which permits fluid to flow therethrough. A spring disposed within the body urges the plunger to the first or disconnect position so that when the connector is not mated, it prevents fluid flow therethrough as well as providing a dust cover for the connector opening.Type: GrantFiled: June 27, 1983Date of Patent: March 26, 1985Assignee: East/West Industries, Inc.Inventors: Dominic J.
