Abstract
796,415. Fishplates. IRVINE, J. E. May 17, 1956 [Feb. 17, 1955], No. 4750/55. Class 104 (2). In an insulated rail joint having two rails 11, 12 sideby-side close together there are provided between the two rails 11, 12 fishplates 15 made of an insulating material and having fitted or moulded into them internally screwed metallic bushes 18 the joint being held together by bolts 17 screwed into the bushes 18. Thick metal packing washers 23 having the same external dimensions as the normal fish-bolt nut are provided with a hole shaped to receive the normal keying rib 21 provided on the bolt 17 and thus fit directly in contact with the head 22 of the bolt 17. The bushes 18 are externally provided with a left-hand thread to hold them in the fish-plates 15 and a flange 20 to prevent the bushes 18 being drawn through the fish-plates 15 by the bolts 17. Alternatively the bush may be provided on its exterior at one end with non-circular flanges or flanges having projections. A shallow depression is provided, Fig. 2 (not shown), in the upper edge of the fish-plate in the centre where they come beneath the rail joint to prevent excessive local pressure in the fish-plate at this point. Specification 796,058 is referred to.
