Abstract
510,938. Pole scaffolding. TRIGGS, W. W. (Safway Steel Scaffolds Co.). March 10, 1939, No. 7768. [Class 20 (ii)] A jack for levelling the bases of scaffold frames comprises a screw 14 with an attached sleeve 15 which enters the end of the scaffold tube 11, a nut 20 with shoulder 28 which engages the end of the scaffold tube, and a further sleeve 16 fixed to the lower end of the screw and adapted to engage over a standard base plate 18. The internal diameter of the lower sleeve is of approximately the same internal diameter as the tubular scaffold members, so that it can fit over, either the upstanding hollow pin 26 of the base plate or over a coupling pin 24 for the tubes, these coupling pins, the sleeve 15 and hollow pin 26 of the base plate being apertured to allow a bent portion 22 of a spring to protrude to grip the internal surface of the overfitting member. The nut is provided with handles 30.
