Abstract
1345063 Railway points ELEKTRO-THERMIT GmbH 22 Oct 1971 [22 Oct 1970] 49236/ 71 Heading E1G In a railway points comprising a pair -of fixed rails 6, 7 cooperable with one or other of two pairs of interconnected movable tongues, viz. main line tongues 2-4 and branch line tongues 3-5, wherein all the tongues are actuated in concert by mechanical, electrical, pneumatic or hydraulic means 14..17, the gaps 18, 19 between the chamfered ends of the point tongues and of the fixed rails are bridged by horizontally retractible wedges 20, 21 which also serve to lock the tongues in position. Each wedge may be actuated pneumatically and engages guide surfaces in the tongues. The sliding surfaces may be coated with p.t.f.e. The wedges may be locked by electrical, pneumatic or hydraulic means and may be electronically coupled to moving parts of the tongues or frog (not shown). The ends of the tongues and fixed rails comprise welded-on portions of martensite-hardened nickel steel.
