Abstract

227,392. Vogel, R. Sept. 18, 1924. Crossings without movable parts.- The wing rails a of a crossing c have a part 3, 4 parallel to the adjacent part of the crossing and diverging portions 2, 3 and 4, 5 leading to the throat and wing of the crossing. In the case of a crossing at a diverging curve, the side c', Fig. 4, is made a chord of the curve, so removing the theoretical point of the crossing from S<1> to S.
