Abstract

235,599. Michl, R. June 13, 1924, [Convention date]. Addition to 191,313. Electric clocks. - In a motor for driving a clock comprising a permanent magnet combined with an alternating-current electromagnet as described in the parent Specification the armature passes between the pole-piece of the electromagnet and those of the permanent magnet. The armature a<1> is a disc divided into segments rotating on a vertical shaft a<2> provided with synchronizing pendulums p. The electromagnet e is provided with a pole-piece e<1> projecting under the armature, and the permanent magnet, which is formed of two bar magnets m, m<1> connected at the top by an iron plate i, with two pole-pieces N, S above the armature. The motor is started by means of a cam 3 engaging with a lever 1 carrying a pawl 2 which engages with a ratchet 7 on the shaft a<2>. The pawl 2 has a tail-piece 2' which is attached to a tension spring 5 and abuts against a stop 6, so that on turning the cam 3 by means of a handle 4 the pawl 2 slips over the ratchet 7 and is afterwards returned by the spring 5, thus starting the motor.
