498,651. Remote-control coupling and uncoupling devices. VEREINIGTE SPIELWARENFABRIKEN A. FORTNER & J. HAFFNER'S NACHFOLGER GES. March 26, 1938, No. 9348. Convention date, Jan. 20. [Class 132 (iii)] A remotecontrol coupling and uncoupling device for toy electric railways consists of an electric operating means, such as an electromagnet w, which rocks a movable coupling member z, characterized in that a switch drum s serving to reverse the direction of running serves for completing the circuit of the coupling operating means w and, for this purpose, is provided with an additional switching member. An electromagnet c is controlled from a switch board and, when energized, rotates a switch drum s one fifth of a turn through lever, ratchet and gear means h, n, o, p, q, Figs. 1 and 2. When contact s<1> on the drum touches spring v<1>, the motor is dead. At the next energisation of the magnet c, contact occurs between s<4> and v<4> and the engine moves forward ; next time s<4> and v' are maintained in contact and s<3>, v<3> and the magnet w receiving current through the cable u is energised and through spring- or weightloaded lever mechanism withdraws the coupling hook z<1> from the link H. At the next turn, s<4>, v<4> and s<3>, v<3> are disengaged and the engine stops ; next the contacts s<2>, v<2> touch and the engine reverses. The link H and hook z<1> are designed to engage on contact, and a similar coupling device may be fitted to the front of the train. The uncoupling magnet w and the contacts s<3>, v<3> may be included in the main circuit or in a separate circuit.
