Abstract An improved cable clamping device which is suitably adapted to hold and support long hanging electrical cables which extend through a continuous shaft between floors of a high-rise building wherein substantially identical members each including an arcuate portion having flanges at opposite ends and a leg depending from the arcuate portion being first angled outwardly and then downwardly substantially parallel to the flanges and each of the flanges has a boss formed therein with an aperture passing through the boss, preferably with one of the apertures being threaded and the other aperture carrying a captive bolt so that with the arcuate portions positioned about the cable tightening of the two bolts presented on opposite sides forms the assembly whereby the downwardly depending legs rest on a floor and firmly hold and support the cable against descention in the shaft. An alternative simplified form may be provided with the leg extending outwardly at a right angle and then only a slight drop downwardly so that the device can rest on a floor or the top of a conduit piece extending between floors.
In combination, a clamp and support assembly for hanging electrical cable in vertical position, and a horizontal building floor having an opening adapted to receive the cable passing through the opening, said assembly comprising a pair of integrally formed cast metal clamping devices each having an arcuate portion engaging the cable with flanges at opposite sides thereof, each flange having aperture means passing therethrough, a leg depending and extending outwardly from the arcuate portion angled first outwardly and then downwardly thereform to provide an assembly with a pair of legs parallel to each other and to the flanges, and bolt means for securing respective adjacent flanges of an opposed pair of said clamping devices together with the arcuate portions positioned about and clamping a cable therebetween and said legs resting on a member associated with the floor and supporting said arcuate portions of said clamping devices over said floor opening.
