Abstract
319,486. Palomeras Mallofre, J. M., and Cardona Nabes, P. Sept. 20, 1928. Lever-actuated platform load-handling appliances. - The platform 8 is carried by the upper members of the lazytongs linkage 7, the lower members being mounted on a shaft 2 supported on the base 1. Slotted extensions 16 of the lazytongs carry racks 15 engaging with pinions on transverse shafts 12 fitted with worm gearing 11 for operation by a handle 9 so as to extend or retract the linkage to raise or lower the platform. Racks 21 pivoted to the cross-bars of the lazytongs are adapted to engage adjacent crossbars so as to give rigidity to the structure when extended. The ends of the racks 21 are connected by cords 22 to facilitate disengagement. A frame 3b is rigidly mounted on the shaft 2 and carries toothed segments 5 engaged by pinions 6 on a cross-shaft which is rotated to tilt the lazytongs sidewise when required, securing bolts 25 being provided to secure the structure in the inclined position.
