Abstract

419,264. Elevating hand - trucks. SIMONSGAARD, P., 155B, Jagtvej, Copenhagen. May 31, 1934, No. 16286. [Class 108 (i).] In elevating trucks the elevating platform is raised and lowered by repeated strokes of the draw bar acting through a ratchet and pawl to turn cam discs or cranks always in the same direction. The draw bar 7 is detachably connected by a link 20 with a lever 17 having a pawl 19 adapted to rotate a ratchet wheel 16 step-by-step. On the shaft 12 of the ratchet wheel are mounted cams 13 of the shape shown bearing against rollers 14 mounted on the elevating platform 9 so that continued rotation of the cams first raises the platform to its full height and then allows it to descend against the action of a dashpot 22<1>. In place of the cams cranks 26 linked to the platform by links 26 may be employed. 419,264.
