Abstract
1,208,012. Conveyer systems. LOCKERBIE & WILKINSON (TIPTON) Ltd. 2 Jan., 1968 [4 Jan., 1967], No. 511/67. Heading B7L. A semi-automatic switch for an overhead trackway for connecting three track elements 10, 11 and 12, Fig. 1, comprises a straight track-connecting element 22 and a curved trackconnecting element 23, Fig. 4, the elements 22, 23 being acted upon by a movable weight 32 so that in a first position of the weight shown in Fig. 1 the element 22 is biased to an operative position connecting the track elements 10, 11 while in a second position of the weight the curved element 23 is biased to an operative position connecting the track element 12 with the track element 10 or, with the element 11, as an alternative. The invention is characterized in that the curved element 23 is pivoted at 40 to the track element 12 and the straight element 22 is movable bodily in directions perpendicular to its length. Both elements 22, 23 are carried by a rotatable shaft 25, the element 22 by an arm 24 and the element 23 through a linkage 36, 37, 38 and 39. The weight 32 is rotatable on one end of the shaft 25 which is mounted in brackets 27 on a plate 28 carried by members 17, 18 of a triangular frame 16, 17, 18 carried by hangers 13, 14, 15. An abutment 33 on the weight is engageable with either an abutment 31 or 30 on the shaft, according to the position selected for the weight by a pull handle 35. In the position shown in Fig. 4 if a load carrying roller hanger moves along the track 11 towards the switch, it operates a pivotal lever 44 adjustably connected by a contact screw with an arm on the shaft 25 to cause the element 22 to assume its operative position against the bias of the weight. Similarly in the position shown in Fig. 1 if a load carrying roller hanger moves along the track element 12 it rides up the element 23 and causes it to move to its operative position against the bias of the differently positioned weight 32.
