Abstract

1330456 Railway crossings BUTZBAOHER WEICHENBAU GmbH 15 Jan 1971 [17 Jan 1970] 2190/71 Addition to 1231845 Heading E1G In the railway crossing frog of the parent specification wherein a resilient point 23 formed by welded-together convergent rails is shifted between wing rails 21, 22 by a slide rod, Fig. 1 (not shown) associated with lost motion locking arms (34, 35), the pivotal connection between the locking arms and the point is modified in that the locking arms are pivoted to a laterally-movable point-shifting element 24 in which the point 23 can slide longitudinally to accommodate temperature changes. As shown each locking arm is resiliently and adjustably coupled to the element 24 through an intermediate element 36 provided with a rubber-bushed pin 38 and an eccentric-bushed pin 39.
