Abstract

324,499. Sands, F. Jan. 4, 1929. Linkage and worm-gearing-actuated hoists with guided platforms.-The lazy tongs linkage 6 is mounted on a shaft 9 supported in the frame 1 which has vertical guides 2 for rollers 4 on the linkage pivot bars 5. The platform 15 is mounted on extensions 18 of the top links and has brackets 16 carrying rollers 17 engaging the guides. Slotted extensions 8 from the bottom links engage pins 10 eccentrically, mounted on a pair of engaging friction or toothed wheels 11. By means of a rocking handle 14 the toothed wheels can be rotated so as to extend or collapse the lazytongs linkage and so raise or lower the load platform. A loading and unloading platform comprises a second lazytongs linkage 22 pivotally mounted on brackets 20 on the frame 1 and having feet 23 adapted to rest on the ground when the platform is turned into a horizontal position and extended. The handle 14 may be replaced by worm gearing.
