Abstract: An electrical wedge connector comprising a shell, and a wedge. The shell defines a wedge receiving passage therein. The wedge is shaped to wedge against the shell when inserted into the wedge receiving passage. The wedge has a conductor receiving channel therein for receiving and fixedly holding a conductor in the shell when the wedge is wedged into the shell. The shell has first portion with a first flexure stiffness generating a first clamping force on the wedge when the wedge is wedged in the first portion of the shell. The shell has a second portion with a second flexure stiffness generating a second clamping force on the wedge when the wedge is wedged in the second portion of the shell.

Abstract: An electrical connector crimping tool die set for crimping an asymmetrical electrical connector onto at least one electrical conductor. The die set includes a first crimping die adapted to be removably mounted to a crimping tool; and a second crimping die adapted to be removably mounted to a movable ram of the crimping tool opposite the first die. The second die includes a generally convex shaped rear side and a generally concave shaped front side. The front side forms a crimping groove with a center axis that is offset from a center axis of the generally convex shaped rear side. The asymmetrical electrical connector can be crimped between the first and second dies at an angle to a center axis of movement of the ram to provide a direction of crimp force substantially along or parallel to the center axis of movement of the ram.

Abstract: A hydraulically actuated tool comprising a frame; a hydraulic fluid pump connected to the frame; a ram movably connected to the frame and adapted to be moved relative to the frame by hydraulic fluid pumped by the pump; and a hydraulic fluid reservoir connected to the pump. The reservoir is located proximate an exterior portion of the frame along a path of at least about 180°0 relative to a longitudinal axis of the tool. The reservoir does not extend beyond a rear end of the frame.

Abstract: A battery operated hydraulic compression tool comprising a frame; a hydraulic fluid reservoir connected to the frame; an electric motor driven hydraulic pump connected to the hydraulic fluid reservoir; a ram movably connected to the frame; and a multi-speed ram advancement system for advancing the ram in at least two different rates of movement on the frame. The advancement system includes a rapid advance actuator located directly against the ram, and a hydraulic bypass system located between the pump and the ram for conduiting hydraulic fluid past the rapid advance actuator to the area of the frame holding the ram.

Abstract: An electrical connector crimping tool head comprising a frame; and a ram movably connected to the frame. The ram comprises a first member and a second member longitudinally movable along the first member. The first member comprises a shaft section removably insertable into a rotatable drive for a fixed connection to the rotatable drive.

Abstract: An operating handle system for a hand-held power tool comprises an operating handle including first and second courses enabling it to be gripped in first and second orientations, respectively. A trigger is movably attached to the operating handle for movement between an operative position for energizing a motor for driving an operating element such as a grinding wheel and an inoperative position at which the motor is de-energized. The trigger includes a first portion associated with the first course and spaced therefrom when the trigger is in the inoperative position and contiguous therewith when in the operative position. The trigger includes a second portion associated with the second course when the trigger is in the inoperative position and contiguous therewith when in the operative position. The first and second courses are mutually perpendicular as are the first and second portions.

Abstract: The hot stick adaptor has two members that are adjustably movable relative to each other. A first one of the members has two separate first ratchet areas. A second one of the members has three separate second ratchet ares. A fastener and spring connect the two members to each other with one of the first ratchet areas and one of the second ratchet areas in interlocking engagement. The two members can be moved away from each other in a first direction, compressing the spring, to disengage the interlocking engagement and thereby allow the two members to be moved in a second direction.

Abstract: A bearing support member, mountable about a support stud, has two support arms extending toward side walls of a rocker arm. A bearing cup is rigidly mounted on each respective side wall and extends over the respective arm of the bearing support member, providing an annulus. Rolling members within the annulus permit the rocker arm to freely oscillate rotatably while being constrained axially. The bearing cups may include a keyed shape to limit orientation of the bearing support member. Another aspect of the invention is a rocker arm subassembly having "open" bearing cups.

Abstract: A bearing support member and bearings form a subassembly that can be inserted, in the direction of the axis of the bearings, into a bore of a rocker arm. A support stud can then be passed through an aperture in the rocker arm and a bore in the bearing support member so as to engage the rocker arm and maintain alignment of the rocker arm and bearings. Also disclosed are an inner sleeve and particular configuration of the bearing support member to facilitate manufacture of the bearing support member by powdered metal forming.

Abstract: A device to determine rotational parameters of a rotatable shaft mounted within a stationary tube comprising a substantially annular shaped target. The target is attached to a rotatable shaft. A target retainer has a bore for receiving the rotatable shaft, and is dimensioned to be securely attached to an interior surface of the tube. The target retainer has a radially extending surface adjacent each axial end of the target to restrain axial movement of the target, and also has an aperture adjacent the outer periphery of the target. A sensor extends into the aperture when the sensor is mounted on the stationary tube. Fasteners connect the sensor to the stationary tube.
