Abstract
345,786. Railway and tramway points or switches. WRIGHTSON, S. S. and MATTHEWS, C. R., Albert Hill Foundry, York Street, Darlington. Feb. 27, 1930, No. 6446. [Class 104 (i).] A stretcher bar CR is connected to the switch rail or tongue TR by means of a lug L provided with a tubular extension T through which passes a T-headed bolt B fixed by a nut N. The bolt has an enlarged part S passing through an elongated slot E in the rail and provided with a curved end to permit a horizontal but not a vertical movement. A spring SP is inserted between the lug and rail, and may be enclosed in an annular flange on the lug. In another form, the lug is separate from the bar CR, and is adjustably connected thereto by bolts and serrated contacting surfaces.
