Abstract: An apparatus for forwardly and laterally indexing a strip provided with an angular blanking pattern along a zigzag path is provided with an adjustable indexing cam mechanism. Forward and lateral indexing assemblies are provided as an integral unit whose operation is synchronized with that of a strip processing machine by means of a direct drive arrangement. The extent of lateral indexing is adjustable by altering the degree of eccentricity of a master cam plate provided within the indexing cam mechanism. The indexing cam mechanism provides the apparatus with dwell periods within which the strip is subjected to one or more operations, for example, blanking, with the dwell periods being independent of the degree of eccentricity of the master cam plate.

Abstract: An internal alignment clamp for use in welding together the confronting ends of a pair of end-to-end pipe lengths comprises a body having an arcuate segment at the opposite ends of which are pivoted a pair of force applying arms movable into and out of engagement with the inner surfaces of such pipes. Mounted on the clamp body is a radially adjustable carriage equipped with a pair of driveable wheels that support the clamp for movement longitudinally of the pipes. An extensible and retractable ram is connected to the force applying arms and to the carriage and is operable to extend the arms and retract the driveable wheels, thereby enabling the arcuate segment of the clamp and the arms to bear against the inner surfaces of the pipes and conform their configurations. An insert is provided to span any gap which exists between the confronting ends of the arms in their expanded positions.

Abstract: A variable length tool in the form of a socket extension, screwdriver or other type of tool or tool holder which includes an externally threaded adjustable shaft having an unthreaded portion to prevent removal of the adjustable shaft from the tool. The body of the tool or tool holder is broached only at the end having an adjustment nut or screw for ease of manufacture and to enable some flexing and bending to a slight degree to eliminate critical alignment problems. In some instances, an adapter having a shear-type retaining pin is provided for over torque protection. The adjustment nut or screw is attached to the body of the tool or tool holder by rolling a portion thereof into an angled groove in the body to form a permanent connection and eliminating the need for a retaining ring and angled surfaces are provided between the tool holder or tool and the interior of the adjustment nut or screw to provide larger bearing surfaces and ease of alignment.

Abstract: A spinner ratchet wrench (10) having a normal ratcheting capability and a free-spinning mode used to easily and quickly pre-tighten a nut or bolt (device) prior to final tightening or to remove a device after it is initially loosened. This feature does not require the handle (18) to be oscillated and is particularly useful when devices are located in areas where finger manipulation is difficult or impossible. Free-spinning is achieved by a combination of a three-position pawl (22a) that includes a neutral position as well as the two standard ratchet positions, and a spinner drive shaft (18a) having at opposite ends a primary bevel gear (18b) and a spin knob (18p). When the pawl (22a) is placed in neutral it is disengaged from the ratchet gear (16f) allowing the shaft (18a) to be directly rotated by the knob (18p). As the shaft turns the primary bevel gear (18b) turns a secondary bevel gear (16d) connected to the socket shank (16k).

Abstract: A combination allen/socket wrench is disclosed of the variety having a spinoff design. This wrench has a handle, a pair of outwardly extending parallel support arms each have a respective end is integral with the handle. A bar is mounted between the arms and transverse axis. A plurality of members are rotatably mounted on the bar which extend therefrom radially of the transverse axis of the bar. Each of these members has the end portion thereof formed having a polygonal external configuration of a varying size to one another and each of these members also has a polygonal socket bore formed therein of a varying size to one another whereby a comination allen/socket wrench is provided. A resiliently-biased detent clamp means provides for selectively retaining each of the members against rotational movement. In this fashion during use of the desired wrench portion, the handle may be pivoted on an axis relative to said desired wrench portion.

Abstract: A tool comprising two jaws, the first jaw having a seat for receiving a shaft to which a split ring clip is to be attached or detached, and the second jaw having a head with two selective indexed positions, the first position for detaching the clip and having prong means adapted to contact the ends of the clip, and the second position for attaching the clip and including a seat for holding the clip with its open side facing the first jaw, a receptacle to catch the clip when detached, and means for moving said jaws together in meshing relationship.
