Abstract

13,159. Newson, C., and Schweikhart, H. A. May 31. Screw-and-nut platform load-handling appliances. - The corner racks of a worm-andrack lift are supported on screw-jacks in order to facilitate vertical adjustment. The cage E is suspended from an open framework composed of four horizontal girders 16 connected by bolts and distance-pieces d, e. Within the framework are arranged two casings 17 free to move laterally on rollers i, i<1>, each casing carrying, between ball - thrust bearings, a pair of vertical screws or worms 18 gearing with quadrantal racks or nuts 13, secured in the lift well. The worms are driven at top and bottom by spur pinions on vertical shafts 21 which are connected by bevel-gearing to the :notor shaft 30 having provision for slight end movement. A groove cut in the under-surface of the thread of the worms engages a similar groove in the upper surface of the teeth of the corner racks, and prevents the worms from leaving the racks. The lift may be driven by a hand-wheel 36<a>, which is put into gear with the motor shaft 30 by manipulation of a handle 41. Fig. 8 shows the jacks for supporting the racks 13. The base-blocks 15 are connected by a web 15<b> and bottom flange, and the adjusting-screws are locked by nuts w.
