The elongated clamping screw is provided with a slot therein for reception of a guide plate also mounted in the main unit to prevent rotation of the screw but to permit longitudinal movement thereof in and out of the main unit.

Abstract: An improved fuse removing apparatus including an elongated housing, a pair of complementary jaws extending generally longitudinally outwardly from the housing for engagement with a fuse. The complementary jaws are secured within the housing in longitudinal sliding relationship such that a plate at the end of the housing forces the jaws towards each other when the complementary jaws are urged into the housing. A cap disposed over the plate causes the jaws to rotate during use so as to lockingly engage the plate and thereby firmly grip a fuse without having to manually rotate the housing. All that is necessary to lock the device onto the fuse is to simply push the apparatus onto the exposed part of a fuse. A minimum of manual rotation is all that is required to disengage the jaws from the locking plate, and thereby release the retained fuse.

Abstract: A pipe welder's aligning tool for use in joining two pipe members end to end comprises a clamp having a pair of jaws movable toward and away from one another so as separably to clamp one pipe member adjacent its end. The jaws carry supports of such length as to extend beyond the one end of the clamped pipe to provide support for the confronting end of a second pipe member that is to be joined to the clamped pipe. To enable the supports to function properly regardless of the diameters of the pipes that are to be joined, the supports are adjustable relatively to their associated jaws. One of the jaws may be mounted on an elongate member which is adjustable to enable the tool to be used on pipes of greatly differing diameters.

A fastener is provided for clamping the adjustable block to the stationary block and passes through a vertical slot in the adjustable block into a threaded bore in the stationary block.

Abstract: An improved fuse removing apparatus including an elongated housing, a pair of complementary jaws extending generally longitudinally outwardly from the housing for engagement with a fuse. The complementary jaws are secured within the housing in longitudinal sliding relationship such that a plate at the end of the housing forces the jaws towards each other when the complementary jaws are urged into the housing. A cap disposed over the plate causes the jaws to rotate during use so as to lockingly engage the plate and thereby firmly grip a fuse without having to manually rotate the housing. All that is necessary to lock the device onto the fuse is to simply push the apparatus onto the exposed part of a fuse. A minimum of manual rotation is all that is required to disengage the jaws from the locking plate, and thereby release the retained fuse.

Abstract: A hand tool is described for holding the front of an electrical outlet box a predetermined distance outwardly beyond the front surface of a stud or other structural member as the box is installed so that when wallboard or other finish material is mounted to the stud, the front of the box is flush with the wallboard. The tool includes jaws for gripping a side panel of the outlet box, indicia for indicating the depth which the side panel is inserted into the jaws, and a spacing member which engages the stud and establishes the predetermined distance between the front surface of the stud and the front of the electrical outlet box. The tool also may include an elevation establishing device for spacing the electrical outlet box a desired distance above the floor. In one embodiment, the indicia comprise pins which limit the depth to which the side panel can be inserted into the jaws. Also, in this embodiment the spacing member comprises first and second spacing bars detachably mounted to the pins.

Abstract: An adjustable off-set spring loaded clamp is provided for assisting in welding, and other operations, and a stand is also provided which supports the clamp in any desired position and orientation. The clamp and stand both include coarse and fine adjustments whereby the jaws of the clamp can be set precisely to any desired initial separation, and whereby the clamp may be adjusted precisely to any desired orientation and held in the desired orientation, so as to enable the clamp to accomplish a wide range of holding functions.

Abstract: Set out herein is an improved conduit cutting guide including a longitudinally hinged handle formed in the manner of a trough and lined with segments of rubber or plastic for grasping the surfaces of a spirally wound flexible conduit therein. One end of the handle is attached to a first set of J-shaped end plates, each end plate being respectively fixed to one of the hinged portions of the handle, the first set of end plates extending above the handle trough to form two outwardly and downwardly directed end tabs. A second set of J-shaped end plates is attached to the respective first set, the second end plates being similarly conformed in plan form and include an offset for receiving the hacksaw blade therebetween. Thus, a conduit may be placed into the interior of the hinged handle and may be grasped thereat by the user. A hacksaw is then insertable into the space between the first and second sets of end plates for cutting the conduit.

Abstract: A clamping mechanism for C-clamps, wrenches, vises and other work holding equipment has a detent as a means to hold the jaws open in a work receiving position with the moveable jaw free of the fixed jaw; a spring or weight bias with dash pot for gentle slow closing bringing the moveable jaw against the work as the work is held against the fixed jaw; a reciprocable manually operated one-way clutch mechanism having a drive and return stroke acting on a sliding plunger supporting the moveable jaw to apply added clamping force on the work between the fixed and moveable jaws; a second one-way clutch engaged with the clamp frame acting on the moveable jaw plunger to hold the moveable jaw in clamping position when the manually operated one-way clutch is in the return stroke and thus not holding the plunger; and a clamp release mechanism which releases the two one-way clutches thus allowing the clamp to be opened against the force of the moveable jaw bias only.
