Abstract
1368894 Railway track crossings ACIERIES DE PARIS & D OUTREAU 19 June 1972 [21 June 1971] 28560/72 Heading E1G In a cast steel railway crossing frog wherein convergent upstream rails 11, 12 cooperate with a movably-mounted point 2 which can swing into engagement with divergent downstream rails 14 or 15, the heel 4, 5 of the movable point 2 is forked to embrace a fixed triangular boss 3 and is retained by a horizontal key 6 having a part-spherical central bearing portion 7 on which the point 2 can swing. The nose of the point is provided with a horizontal shifting bar (not shown) which passes through apertures 16, 17 in the rails 14, 15 and may be actuated by worm gearing. The point 2 seats on bearing plates 13 and has its forked heel bevelled at 9, 10 to coact with the bevelled ends of the upstream rails 11, 12. (For Figures see next page)
