Abstract

21,967. Duplock, W. Sept. 29. Track apparatus actuating signals on trains. -An arched bar 1 pivoted on the track tu coact with various forms of apparatus on the train is provided with an extension 6 to the end of which is secured a spring 7 which maintains the bar in a raised position. The engine contacts described are levers with rollers or rounded surfaces providing ample allowance for lateral movement of the train passing over the track contact. The signals may be electrically or mechanically actuated, and restoring-springs may be used.
