Abstract
6211. Nitschke, K. March 12. Load - handling appliances. - Comprises a telescopic tubular mast for lifting and other purposes, in which the sections are raised progressively by a flexible steel band and are automatically locked in the extended position. Fig. 2 shows a detail view, and Fig. 3 is a sectional elevation of the apparatus. The tubes are raised by a band a which is stepped to correspond with the various diameters of the tubes so that it always fits the diametrical section of each tube and is thus kept rigid. The band is wound on a drum l and passes between two rolls h, i the drum being driven from the roll i by chain gearing k. Projections on the rolls engage with perforations in the band and keep it central. Each tube is locked, until the one inside it has been raised, by a pin d carried by a lever b the lower end of which is actuated by the shoulders on the band a and thus the tubes are released in turn. As the tubes are extended each section is locked to the next by a split clamp q which is tightened by an arm o actuated by a pin m on a fixed bracket n. When the band is lowered, the sections are released in order as they come down, so that the band is always rigid in the tubes. In a modification, the band a may be tapered instead of stepped.
