Abstract

579,464. Scaffolding clamps. HOWARD, T. W., KETHRO, G. E., STOODLEY, H. H., and STYCH, A. Feb. 8, 1944, No. 2319. [Class 20 (ii)] A scaffolding clamp comprises a frame receiving two tubular scaffold members to be coupled together, the scaffold members being forced into gripping contact by a clamping plate bearing on one of the scaffold members and actuated by a cam. The frame 1 may be of U-form in section to embrace one scaffold member 4, the sides of the frame being apertured at 5 to accommodate a second scaffold member 8 which slots in a groove in a clamping plate 7 housed in a recess 6 in the frame. A rotary cam, journalled in pockets 10 in the frame, has two bearing surfaces 12, 11 the latter being at slightly greater distance from the cam axis than the former. Scaffold tubes 4, Fig. 6, may be joined end to end by a piece 19 with spigots 18 inserted within the tube ends, the tubes being clamped by a parallel short tube 20 engaged by the cam-operated clampplate 7. The clamping plate may be provided on its working face with a vertical, horizontal and diagonal groove to suit various dispositions of the scaffold tubes to be joined. The clamping plate may alternatively be circular with a diametral groove on the working face, notches being provided on the periphery of the plate to engage the parts 6 of the frame to prevent rotation of the plate from the set position. The rear wall of the recess 6 is tapered downwardly to tend to urge the clamping plate against the scaffold tube.
