Abstract: 810,699. Conveyers for delivering goods at predetermined positions. VALIDA MASKINER A.B. Jan. 16, 1957, No. 1602/57. Class 78 (1). A conveyer for delivering articles carried on hangers at predetermined delivery stations comprises at least one carrying member depending from and movable along a track and provided with a plurality of hanger-carrying elements, each hanger-carrying element consisting of a transverse spindle having one end portion bent up at an oblique angle to receive a hanger, the spindle being rotatable by means provided at a predetermined station along the track adapted to engage a radially extending portion of its other end portion so as to turn the spindle into a position in which the bent-up end portion is turned downwardly to discharge the hanger by gravity. In one form, Figs. 1, 2, the carrying member 3, of which a plurality are secured to an endless chain 21, comprises a pair of carrier plates, the upper ends of which are supported by rollers 2 from a track 1 whilst a number of transverse spindles 5 are carried rotatably between their lower ends. Spindles 5 have one end 6 bent upwardly at an oblique angle to support one or more hangers, white their other ends 7 extend radially for engagement by a trip lever 8 at a predetermined station. Lever 8 is carried on a shaft 10 extending parallel with the conveyers and which also carries a lever 13 having a roller 15 engageable with an inclined leading edge of one of the carrier plates, the shaft being biased by a spring or weight to maintain lever 8 raised. The roller 15 is depressed by each passing carrying member, causing the lever 8 to strike the end 7 of one of the spindles to discharge the hanger thereon. The longitudinal spacing between the levers 8, 13 is varied at the various stations so that each of the spindles 5 on a carrying member 3 is discharged at a different station. A pair of guide rollers 18 is provided at each station to steady the carrying members. The discharged hangers at each station are received on a tubular rail 20. Inverted U-shaped brackets 12 support the rail 20 and also the shaft 10 at each station from the track 1. In a modified form, Figs. 3, 4, the lever 13 at each station is replaced by a lever 23 carried on a separate shaft 24 which is coupled to the shaft 10 by levers 26, 28 on the respective shafts and a weighted link 27. The destination of the individual hangers on a carrying member 3 is determined as before by the different longitudinal spacing of the levers 8, 23 at each of a group of stations, but in this form a number of groups of stations are provided, each group being selectable by the vertical disposition of a roller 22 on each carrying member which is engageable with a sloping surface 25 carried by the lever 23. The height of the shaft 24 is different for each group of stations so as to correspond with the vertical settings of roller 22. Adjustment of roller 22 on each carrying member is effected by mounting it on a slide 31 which is slidable and rotatable on a shaft 32 mounted in the carrying member 3, a spring 35 being provided to urge the roller spindle 30 into engagement with a selected one of a series of notches 34 in one of the carrier plates, the desired notch being chosen by manipulation of a handle 36.
