Abstract: A device for transversely shearing a conduit including a first handle having a recessed conduit-receiving jaw at one end thereof, a shearing blade pivotally mounted on said first handle at the location for pivoting toward and away from said jaw, and including a plurality of ratchet teeth along one edge thereof, and a second handle pivotally connected to said jaw. An elongated toothed pawl bar having an elongated slot near one end thereof, and having pawl teeth at the other end thereof, is pivotally secured by a pivot pin extending through said slot to said second handle at a point spaced from its point of pivotal connection to said jaw. A cam stud secured to said first handle bears against one side edge of said pawl bar opposite the edge upon which the pawl teeth are located, and functions, when the handles are pivoted toward each other, to cam said pawl bar to a location at which said pawl teeth engage said ratchet teeth.

Abstract: An electrical switch or receptacle box for mounting in a wall, ceiling or the like, including a pair of opposite side walls having retaining studs of triangular or wedge-shaped configuration molded integrally therewith, and terminating rearwardly from the open forward side of the box. The box further includes a pair of integrally molded cover plate flanges which flank the opening at the forward side of the box. Each of the flanges carries a metal insert-receiving lug on the rear side thereof, and each of these lugs is slotted to engage an apertured metal insert which is positioned to receive through an aperture therein, a mounting screw extended through the respective flange and used to mount a cover plate carrying a switch or electrical receptacle on the box.

Abstract: An electrical outlet box mounting bracket assembly including a box of generally rectangular parallelepiped configuration, a pair of spaced channel elements on a side of the box, and an L-shaped bracket including a flange having side edges extending into the channels to engage the bracket with the box. The bracket further includes a pair of flexible tongues adjacent the side edges of the flange, which tongues engage tabs at the ends of the channels.

Abstract: A clamping device comprising an elongated wedge body having a bifurcated end, and a second end opposite the bifurcated end. The wedge body is of substantially rectangular transverse cross-sectional configuration, and is relatively thick at the second end, tapering to a relatively thin dimension at the bifurcated end. The wedge body has first and second sides extending between its bifurcated and second ends. Each of these sides carries a plurality of longitudinally spaced, contiguous teeth or serrations over a major portion of its length. The bifurcation in one end of the wedge body defines a pair of spaced, substantially parallel legs, which legs have continuations of the teeth or serrations extended along one side thereof, and are relatively smooth on the opposite side thereof. In a useful combination, the clamping device retains an electrical conductor in place at the location where it enters a knock-out window in a synthetic resin electrical box.

Abstract: A device for clamping conduit which includes a U-shaped body portion having a recess therein located between two legs of the body portion, and a toothed jaw portion positioned at the bottom of the recess for engaging a pipe or conduit. A clamping portion is hingedly secured to one of the legs of the body portion at the free end thereof by an integral flexible hinge, and is adapted to fold about the hinge to enclose the pipe or conduit in the recess by means of a second toothed jaw portion formed on the clamping portion. Each of the legs of the body portion carries a protuberant apertured flange with the apertures in the flanges positioned for alignment with corresponding apertures in the clamping portion when the clamping portion is pivoted to its recess closing position. The aligned apertures in the flanges and clamping portions can then be used for receiving fasteners extended through these apertures and into a supporting surface such as a wall or the like.

Abstract: A spring fastener or clip of generally V-shaped configuration and including a first, substantially monoplanar leg joined to a second, substantially monoplanar leg through a bend portion so that the legs define between them an acute angle from about 43.degree. to about 48.degree.. The second leg has a circular aperture formed through a central portion, and the first leg has a tongue or tine pressed out of a central portion of the first leg and projecting generally toward the center of the aperture in the second leg, and at an acute angle of from about 22.degree. to about 28.degree. to the plane of the first leg. The tongue projects a distance from the plane of the first leg, as measured normal to that plane, and so as to include the thickness of the first leg, which is from about one-half to about two-thirds of the total distance of projection of the bend portion of the fastener from the plane of the first leg, also as measured normal to the plane of the first leg, and so as to include the thickness thereof.
