TY - JOUR AU1 - Fridland, A. AB - mounted on the supply panel A drum with the electric a 5 kw electric motor via a three-speed reducing gear; cable is located at the beginning of the inspection bed the second roller is free running. The arming mechanism and is not connected with the machine. is actuated by a 10 kw electric motor which transmits the rotary motion to the shaft via a worm gear of 1 : 60 gear ratio. The rotary motion from the cylindrical part of the shaft is transmitted through a clutch and a universal joint to the turning mechanism. In this way it is possible to transmit the rotary motion irrespective of the incli- nation angle of the grooved shaft. The turning apparatus consists of a grooved shaft and turning head (Fig. 2). The fork of the head engages the rail by means of a system of levers and then the rail is turned when the shaft rotates. The turning mechanism is designed in such a way that the engagement of the fork with the rail can be ef- -4 fected in any position of the rail (with the rail resting on its head or its foot or on edge).
