Abstract 959,943. Endless conveyers. G. M. PFAFF A.G. Feb. 18, 1963 [Feb. 19,1962], No. 6389/63. Heading B8A. An endless conveyer 1 for workpiece carriers 7 each having a hook-shaped suspension member 7a received on a conveyer member 4 by a supporting member 8 and which are deposited automatically on receiving bars 29 at predetermined delivery stations is characterized by a V-shaped supporting member 8 mounted on a spindle 6 and co-operating with stationary guide rails 30 at the delivery stations. A conventional selector device 31 with contact member 32 cooperates with switches 33 actuating a push-rod 39 of an electromagnet 38 to push a release lever 34 from its normal spring-retained (dotted) position into the path of a control rod 18 where it is retained by a spring latch 40. This causes the rod 18 to rotate against a spring 20 and tilt a control disc 9 attached to the spindle 6 through a driver 22 engaging a pin 24 on the control disc, a pin 26 sliding in a slot 28 in a wall 5 limiting the angle of tilt. Sideways movement of the conveyer member 4 is limited by a roller 47 engaging a guide 46. The hook 7a slides down the arm of the V and engages a guide rail 30 at the end of which it drops on to a receiving bar 29. When the conveyer member 4 has moved sufficiently for a roller 15 on the rod 18 to clear the release lever 34 the roller 15 under the returning action of the spring 20 on the rod 18 forces the latch 40 to release the lever 34 which is returned to its inoperative position by a spring 37. At the same time an aim 12 attached to the rod 18 acts on a rib 10 on the control disc 9 to return the support 8 to its initial position where it is held by the arm 12 and a corresponding arm 11 on the symmetrically arranged rod 17.
