Abstract

433,624. Retractive switches. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and SMITH, S. R., Rock House, Old Swan, both in Liverpool. Feb. 17, 1934, No. 5298. [Class 38 (v)] A switch operated by the passage of a road vehicle comprises a resilient rubber pad 10 mounted transversely in the road and held in position by bars 14, 15, which are formed with flanges engaging grooves in the pad so as to form a water-tight closure and to prevent displacement by the traffic. A resilient metal contact strip 16 which may be of stainless steel is mounted on the underside of the pad 10 and is adapted to engage with two contact bars 17, 18 insulatedly mounted on a hard rubber bed 19. The cables are brought up through a duct 41 into a compartment 22 arranged at the side of the pad at one end. Connection is made to the contact strip 16 by means of a spring 32 bearing on the underside of the strip and connected by insulated bolts 34, 35 to an insulated bar provided with a terminal. Similar springs, (not shown), serve for connecting the bars 17, 18. Specification 360,924 is referred to.
