Title: Improvements in conveyors
IPC: B65G25/00
Filed: 1942-09-01
Abstract: 561,182. Step - by step conveyers. SUMMERS & SONS, Ltd., J., and JONES, J. F. R, Sept. 1, 1942, No. 12321. [Class 78 (i)] Relates to a conveyer of the walking beam type in which articles or materials are supported on a floor consisting of two groups of rails 1, 2, which are reciprocated in one direction and lifted and lowered in turn by the oscillation of yokes 10 which are pivoted about horizontal axes and support the rails of the two different groups on opposite sides of their pivots, each group being first raised to lift the load from the other group, then displaced longitudinally, then lowered to lower the load on to the other group, and finally displaced longitudinally backwards clear of the load. According to the invention, the yokes support the rails by means of arcuateended struts 7, 13 inserted loosely between the yokes and the rails at an angle to the vertical so that the struts are driven frictionally from the yokes, and, as these are oscillated, the struts are lifted, the weight upon them causing them to move through an angle in a vertical plane to displace the rails they support longitudinally in that plane. The invention may be used, for example, for conveying wool tufts through wool drying machinery, biscuits,. &c. through baking ovens, and steel billets &c. through annealing and reheating furnaces. As shown, the rails 1, connected by cross-ties, have wear-plates 5 supported by and in rolling contact with the arcuate ends of the struts 7 supported on pivoted bearings 8 on one set of arms 9 of the yokes 10, the other set of arms 11 of which support bearings 12 for the struts 13 having arcuate ends 14 bearing on wearplates 15 attached to the rails 2. The bearings 12, however, may be disposed on the rails and the bearings 14 on the yokes. Crank arms 17 on the yokes are interconnected by rods 18 which are moved to oscillate the yokes by a link 16 connected to an eccentric 19 on a rotatable shaft 20 which also carries eccentrics 21, 22 with elliptical sheaves 23, 24 connected respectively to levers 25, 26 oscillatable on a pivot 27 and connected in turn by links 28, 29 to the two sets of rails 1, 2. Owing to the elliptical shape of the sheaves there is a lostmotion period in the reciprocating drive to the rails during which the link 16, and with it the yokes 10, are actuated to lift the rails 1 or 2. Where, as shown, the groups of rails differ in numbers, the extra weight of the heavier group is counterbalanced by a beam 30 mounted on a fixed pivot 31 and pivotally connected at 32 to the rod 18, its free end having an adjustable weight 33. The rails 1 or 2 may be connected at their ends by a flat spring plate disposed in a horizontal plane to give flexibility to the joint in a vertical plane.
