Abstract: Apparatus useful in repair of a termination of an outer cover of an armoured cable. The outer cover comprises a number of wires and the termination is effected by location of the wires between an inner body within the outer cover and an outer body outside the outer cover.

The two blocks can be forced apart to separate the inner and outer bodies and thus open the termination. A wire separator retains the wires of the outer cover separate after the forcing open of the termination. The apparatus is useful aboard ship whereas previously cables could only be reterminated in part.

Abstract: A method and apparatus for dismounting a trunnion bearing from a universal joint utilizes a plate that is secured to the proximal arm of one yoke of the joint through which dismounting bolts are threaded into contact with the other joint yoke. Further threading of the dismounting bolts into the plate causes the one yoke secured to the plate to move along a pin of a crossed-pin member of the universal joint, bringing a pin end into contact with the trunnion bearing in the distal arm of the one yoke, thereby urging it out from its press-fitted position in that arm.

The seizing mechanism comprises a pair of adjacent vise blocks (15, 16) having aligned holes (19) to correspond to the locations of the keying pins (13). When the card (27) is fully inserted in the guide frame, the keying pins (13) of the keying block (12) pass through the aligned holes (19) of both vise blocks (15, 16). The latter blocks have opposing parallel faces (20, 21) lying at an angle to the axes of the keying pins (13).

Abstract: The ram of a vertical milling machine is raised up from the machine base and then secured thereto in a raised position to accommodate a workpiece having a vertical dimension that is greater than the normal vertical clearance between the tool spindle on the ram and the work support table below the spindle. The method involves removing the bolts which mount the ram on the base, threading long guide screws into these bolt holes and supporting an inverted U-shaped bracket on nuts threaded on the guide screws such that the bracket is disposed in an elevated position above the ram. A lift screw is then extended downwardly through the bight portion of the bracket and is threaded into the conventional threaded eye bolt opening on the top side of the ram. Thereafter, a nut is threaded down on the lift screw against the top side of the bight section of the bracket and continued rotation of the nut causes the lift screw to be displaced upwardly to raise the ram as it is guided by the guide screws.

Abstract: Apparatus for removing a valve adjusting disc from a valve lifter in a valve mechanism of an engine cylinder head includes an elongated rigid cross-bar supported on the engine cylinder head and extending generally parallel to the camshaft above the valve lifters. A force-applying member slides on the cross-bar and is straddled by an adjustment screw retainer that also slides on the cross-bar. The force-applying member has a downwardly extending arm with a lower working face that contacts the valve lifter independently of contact with the valve adjustment disc. An adjustment screw carried on the retainer is turned to apply downward force on the force-applying member, which forces the arm downwardly against the resistance of the cross-bar for compressing the valve lifter against the bias of the valve spring.

Abstract: An extractor for the flanged tubular ferrule which surrounds the head of the barrel lock of a kilowatt-hour meter comprises an actuating screw and a two-piece clamp. The clamp has a threaded hole and two recesses of different diameters, the larger of which is adapted to fit around the flange of the ferrule and the smaller of which is adapted to fit around the body of the ferrule. To remove the ferrule, the two pieces of the clamp are fitted over the ferrule and then fastened together by bolts. Then the actuating screw is screwed into the clamp until the inner end of the screw abuts against the head of the barrel lock which is inside the tubular ferrule. Continued rotation of the actuating screw in a tightening direction causes the clamp to move outwardly on the threads of the screw and in so doing the captive ferrule is pulled out of the cover housing. Following removal of the ferrule, the barrel lock itself may be removed by a barrel lock extractor, preferably of the type described in my U.S. Pat. No.

Abstract: The end cap separating tool of this invention comprises a pair of spreader blocks, generally U-shaped in plan, the projecting ends of which clamp by means of anchor screws to adjoining end cap halves adjacent their outside edges. A T-handled actuator screw is threaded through a tapped opening in one block and the end of the screw opposite the handle is attached rotatably to the second block, whereby rotation of the screw in one direction moves the one spreader block away from the second, thereby separating one end cap half from the other and from the telephone cable. The other end cap half is separated from the cable by a cord extended across the cap diameter, under the telephone cable and up the opposite side of the cable to the one block where it is secured. Rotation of the screw in the direction to move the one block away from the second block engaging the end cap half results in lifting and rolling the cable away from the end cap half.

Abstract: A wheel hub moving tool has a pair of diametrically opposed clamping members adapted to cooperatively clamp the tool on a wheel axle. A specifically designed link chain pivotally secured to one of the clamping members embraces a portion of the axle to assist the clamping members in resisting axial movement of the tool while moving the wheel hub. An axially disposed threaded bolt engages an entrapped nut supported on one of the clamping members whereby rotation of the bolt causes the bolt to move axially with respect to the clamping members and thus push the hub away from the clamping members. A rotatable spool is provided on one of the clamping members. A flexible strap which may be secured to the hub and wound on the spool is used to pull the hub toward the clamping members.

Abstract: A tool is used to move the piston into the cylinder bore of a disc brake caliper housing having a support bracket with an opening disposed opposite the piston.

Abstract: A sheave for a speed variator comprising a fixed and a movable side mounted for rotation with a common shaft. A diaphragm spring urges the movably slide towards the fixed side to clamp a V-belt therebetween. The fixed side may be removed and turned around and then tightened with its own threaded fastener on the shaft to urge the movable side against the force of the diaphragm spring to a retracted position. A retaining member, e.g. a screwdriver, cooperates with the movable side to temporarily hold the same in its retracted position while the fixed side is removed again and turned around and secured by the threaded member in its normal position. The V-belt is then repositioned between the side and the retaining member released. Alternatively, the retaining member may be released automatically, e.g. centrifugally, when the variator is set into motion again.
