Abstract
434,513. Step - by - step conveyers. MAETZ, 0., 3A, Geibelstrasse, D³sseldorf, Germany. Oct. 11, 1934, No. 29168. [Class 78 (i)] [See also Group XII] In a step-by-step conveyer for glass-annealing leers of the kind comprising alternate fixed and moving bars 20 supported respectively by transverse beams 22, 39, the latter carry U- shaped bar - supporting elements 23, Fig. 4, formed with a projection 30 and cut-away portions 26, 32 which provide, on assembly, recesses to receive the offset overlapping ends 35 of the bars 20, these ends being slotted for the passage of the projection 30 which is secured to the adjacent element 23 by a clamping screw 31. The beams 39 carrying the moving bars 20 are attached, by means permitting limited vertical and transverse movement, to channel bars 42, Fig. 8, arranged outside the leer and carrying wheels 58 running on rails 59, the latter being supported by links 60 pivoted to fixed pillars 61. The longitudinal movement of the bars 42 is effected by motor-driven cams 65 and cranks 66, the latter being mounted on the cams by means of nuts and screwed spindles 68, which are rotatable by bevel gearing 70, 71, 72, to vary the throw of the cranks. The vertical movement of the conveyer bars is effected by raising and lowering the rails 59, these being connected by adjustable screwed rods 78 to bell-cranks 77 which carry rollers 75 bearing on the cams 65. Each of the cross beams 39 carries a tube 53 for the passage of cooling air, the ends of these tubes extending through the channel bars 42 and being connected to provide a continuous zig-zag cooling pipe.
