Title: Improvements in or relating to conveying systems
IPC: E04H6/14
Filed: 1929-03-27
Abstract: 308,735. Associated Electrical Industries, Ltd., (Assignees of James; H. D.). March 27, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Driving-gear for endless-chain elevators; stopping on breakage of chains ; lift cages; carriers, attaching to chains. - Comprises an elevator system shown as applied to a several-storied building forming a garage, the cars being raised to the various floors by trains of cages attached to endless chains' or the like, which are driven at several points of the run. Fig. 1 shows a building 10 with four rows of conveyers A - - D, each passage-way 11 being served on one side by the cages 13 of one row of elevators and on the other side by the cages of another row. The elevator chains are driven bv reversible motors from at least two points such as 16, 17, the uppermost motor being double the power of the others, and are guided in the vicinity of the driving-gears. The motor 18, Figs. 8 and 10, drives the wheels 33 by spur gear. Sprocket wheels 31, bolted in adjustable position to the wheels 33, engage the links of both runs of chains 13. Each sprocket wheel has two parallel sets of teeth engaging the roller-occupied spaces 26, Fig. 4 of the chain, the middle set of links 25 passing freely between the two sets of teeth. The cages are slung from the projecting members 29 on some of the links. If the chains jump the flanged pulleys 14, Fig. 14, at their upper ends, they exert pressure on the cover plate or shield 43 and operate electric cut-outs 44 to stop the motors. The lowest pulley, Fig. 16, is associated with screw-and-nut chain-tensioning mechanism 46, and sufficient slack is left in the chain to prevent excessive strain when the load' is travelling horizontally at the lowest point. The rim of the lower pulley forms a perforated oil container which lubricates the chain-engaging periphery. A pump 50 collects the drippings from the pans 52 and re-delivers them, together with fresh oil from the reservoir 51, to the open inner side of the container. Each cage comprises a beam 53, Figs. 18, 19 connecting two projecting chain members 29 and carrying a pair of straps 54 supporting an upper platform 20 comprising a pair of braced beams supporting a track for the truck 22. A similar lower platform is suspended by the links 59. The parts are readily disconnectible. Fig. 21 shows means for stopping the elevator if one of the connecting pins 27 of the chain becomes loose and is displaced from its proper position. The projecting end of the displaced pin actuates one of the levers 72, 73 and breaks the contacts 75, 76. The longer cagecarrying pins 29 actuate both levers 73, 74 in unison and do not break the contact in passing.
