Relates to the controlling &c. of continuouscurrent motors for lifts, hoists, cranes, &c. and for other purposes, and consists of (1) apparatus for automatically cutting out the starting resistances, and putting them in on stopping or reversal ; and (2) multiple-contact switch apparatus. Fig. 1 shows the winding-drum shaft A with a wave-groove B which, as the drum rotates, gives an oscillatory movement to an arm C, linked by a bar D to a crank carrying a pawl which engages with a ratchet-wheel E frictionally engaging with the switch arm F. When the motor is started the arm F is automatically rotated from the position shown until it is at the lower end of its slide, and the starting-resistances are out of circuit. The wheel E then slips, without moving the arm F. A second lever L, pivoted at G, engages by one of its ends with a cam-groove J on the stopping and reversing shaft K. The effect of the rotation of this shaft is, as shown in Fig. 2, to move the switch arm F to its initial position. In a modification, the shaft A is fitted with two spur pinions, which engage with racks attached to the outer end of the switch arm F. One operates the switch when the drum is started in one direction, and the other when the drum is started in the opposite direction. In another modification, a reciprocating pawl engages with a ratchet-wheel with teeth on part only of its periphery.
