Abstract

193,230. Butler, G. H. C., and Reeves, A. Jan. 11, 1922. Screw-and-nut actuated linkage load-handling machines.-In jacks of lazy-tongs construction the load is engaged by a small plate or disc 24 which is rotatably mounted at the centre of a platform 22 having a downwardly-projecting slotted limb 23 engaged by the pivot pin 11. A strengthening pin 5 bridges the pair of lower links 3 and passes through slots 4 in the links 2.
