Abstract: A multi-purpose tool is provided and includes first and second elongate body members each having first and second ends. A torque surface is formed at one of the first and second ends of each of the body members. The torque surfaces are adapted for engagement with workpiece surfaces such as the flats of polygonal fastening elements. Driver heads are formed at the other ends of the body members and are adapted for engagement in slots of slotted fastening elements with the first body member driver head configured differently from the second body member driver head. The body members are secured together to allow relative movement therebetween with the torque surface of the first body member and the torque surface of the second body member generally facing each other to define an adjustable opening therebetween. The driver heads of the body members are adjacent to each other for exposing one of the heads beyond the other.

Abstract: A snap-fit self-adjusting ratchet wrench which has two guided jaws which move linearly against each other along a guided pin, and which are hinged to a handle by pins. The hinges on the jaw to the handle are designed with override leverage wherein the gripping force is increased as the handle is swung in forward stroke and releases in back stroke to provide ratchet action. A return spring exerts force on the jaws for an automatic snapping on the workpiece. A locking mechanism may be provided by a fastening means for retaining the guiding pin to hold the jaw opening to a fixed predetermined position.

Abstract: A push-to-connect fitting for sealed connection to a synthetic resin tube end. The fitting includes a body, an eyelet, a nut threadedly connected to the body, and a radially constrictible sleeve for retaining the tube end effectively positively within the fitting. The fitting is arranged to be connected to the tube end by a coaxial insertion of the tube end into the fitting with the tube end being received between the sleeve and the eyelet in moving to the fully inserted position. The sleeve is provided with annular gripping portions, one of which is slidably engaged by the tube end as it is inserted into the fitting. The one tube portion is arranged to be mechanically interlocked with the tube end as a result of an outward movement of the tube end from the fully inserted position whereupon the sleeve is concurrently urged axially outwardly with the tube end.
