Abstract

528,527. Operating railway switches. WILLIAMS, Ltd., H., and WILLIAMS, D. D. May 6,1939, No. 13577. [Class 104 (i)] The switch-operating lever a is connected to the lock plunger l by mechanism d, e, f, h<SP>1</SP>, i<SP>1</SP>, j, k, so that the switch movement takes place only when the plunger is nearing the end of its withdrawal and during the commencement of its return movement. The switch is operated by the lever a through an escapement lever b, and the levers h<SP>1</SP>, i<SP>1</SP> are pivoted on fixed plates h, i, and are connected by a toggle link j, so that movement of the mechanism in the same direction effects both withdrawal and return of the plunger.
