899,772. Transitional type couplings. HILGER, O., and BUSCH, W., [trading as BERGISHE STAHL-INDUSTRIE REMSCHEID]. Dec. 15, 1958 [Dec. 21, 1957], No. 40348/58. Class 103(5). A transitional type coupling which transmits full draught load but is protected by side buffers from most of the buffing load, comprises an automatic head 11, a link 13 pivoted to a pin 14 in the head and connecting the head to a draw-hook 15, an angled member 19 on each side of the hook pivoted to a pin 20 in the hook, pre-loaded compression springs 17 having abutments 16, 16a at each end universally jointed to the pin 14 and the members 19 respectively, and pin and slot connected telescopic members 24, 25 joining the abutments. The head may be lowered and hung by its link 13 in an out of use position by lifting the head and disengaging the link 13 from the hook, the members 19 pivoting freely forwards about the pin 20 to allow this to be done, Fig. 4 (not shown). In the coupling position, the head is supported by co-operating abutments 33, 34 on the eye and head respectively and by the springs 17, which springs .since they are universally mounted on the pivotable members 19 also allow limited movement of the head in a horizontal plane, and the members 19 are forced against abutments 26 on a forked member 27 having limbs on either side pivoted to the pin 20, the bridge part 29 of the member 27 having an adjustable screw 30 which abuts the draw rod 28 to fix the positions of the abutments 26 and also permits the head to be raised or lowered slightly with respect to the rails. Instead of the described link members, a triangular link member may be pivoted at its upper corner to the hook and its its forward lower corner to the spring, its third corner abutting the hook shaft to limit the motion of the triangular link. It is also possible to arrange the springs above the longitudinal axis of the coupling, the rear portions of the springs being pivoted directly to the hook whilst the forward portions are linked to the coupler head.
