Mount for electrical junction blocks

Claim 1

A mount for junction blocks to which electrical wires are connected and having a pair of generally flat and parallel side faces, one of which has a rib projected from it and the other of which has a groove opening out of it; said mount comprising: a track having opposed sidewalls which are resiliently mounted with respect to one another and are spaced apart a distance substantially equal to the spacing between the side faces on the block so that block will fit between the sidewalls, one of the sidewalls having a longitudinally extending rib projecting from it for entry into the groove on the block and the other sidewall having a longitudinally extending groove in it for receiving the rib on the block, each sidewall further having a beveled surface which is inclined relative to the general direction of the wall and faces away from the space between the walls, each sidewall further having a slideway extending longitudinally along it; a slide spanning the space between the sidewalls and engaged with the slideways along the sidewalls such that it will move along the slideways unless otherwise restricted, the slide being shorter than the space between the outer edges of the slideways so that the walls can move together without interference from the slide; a cap overlying the slide and bridging the space between the two sidewalls, the cap having beveled surfaces which abut the beveled surfaces of the sidewalls; and a screw extended through the cap and threaded into the slide for drawing the slide and cap together, whereby the beveled surfaces on the cap will move down the beveled surfaces on the sidewalls so as to urge the sidewalls together, thereby clamping the blocks tightly between them, and whereby the friction between the cap and slide and the sidewalls is increased, thereby securing the cap and slide firmly in place on the track and preventing movement of the blocks longitudinally of the track.
