898,608. Transferring rod-like articles from one conveyer to another. T.I. (GROUP SERVICES) Ltd. Nov. 5, 1959 [Nov. 5, 1958], No. 35505/58. Class 78 (1). Rods 6 are transferred singly from a bundle of rods on an endless conveyer band 5 by a pair of laterally spaced grippers adapted to grip the rods by rotation thereof, the grippers being carried by a frame 12 which is reciprocated between the full-line gripping position and the chain-line releasing position, in which latter the grippers release each rod on to a rollerway 21 which carries the rods from the grippers. Each gripper consists of a pair of pins 17 projecting from a circular plate 18 which is carried by the frame 12 and rotated by a fluid-pressure cylinder 20 to cause the pins 17 to grip and release a rod 6. The frame 12 is mounted on a shaft 10 journalled between a pair of arms 8 pivotally mounted at 9. A fluid-pressure cylinder 13 acts on a lever 15 secured to the shaft 10 to raise and lower the frame 12, and another cylinder 25 is arranged to swing the arms 8. An adjustably mounted plate 16 is carried by the frame 12 in advance of the grippers. In operation, the rods 6 are advanced up to stops 7 whereupon a switch (not shown) is actuated by the leading rod to initiate a cyclic operation of the cylinders 13 and 20 whereby the grippers grip the leading rod, after which the frame is lifted so that the gripped rod clears stops 7 and then swung to the chain-line position, the grippers are then re-opened to deliver the rod to the rollerway 21, and finally the frame is returned to the full-line position. During the return movement, the plate 16 engages any rods lying on top of the leading rod in the bundle and pushes these back so that the rods are positioned in a single layer adjacent the stops 7.
