Abstract: 8558. British Thomson-Houston Co., [Linn, J. B.]. April 12. Electric locomotives and motor vehicles.- Relates to mastercontrol systems for electric motors, in which each of the motor - controllers is of the separatelyactuated contact type. The system is a modification of that described in Specification No. 8557, A.D. 1902, and the arrangement is such that, when the master-controller has been moved to one of its operative positions, the resistance - controlling contacts of each motor-controller will be operated automatically one after another at intervals dependent upon the value of the current in the motor circuits. The invention is illustrated as applied to a control system similar to that described in Specification No. 20,275, A.D. 1898, and having actuating circuits connected as described in Specification No. 13,721, A.D. 1900, [Abridgment Class Electricity, Regulating &c.], while the reversing-switch employed is of the kind described in Specification No. 21,550, A.D. 1898. Fig. 1 is a diagram of the control and power circuits of one motor car of a train, the control circuits being connected thronghout the train by a set of wires 1, 2, and 3. M', M' are the propelling-motors, D the motor-controller, and E the reversing-switch, the whole being under the control of one of the master-controllers C, C<1>. The motor-controller D comprises a series of electromagnetic switches, viz :-a main circuit closer T', a series switch S, two parallel switches P, P', and a number of resistance switches R to R<5> for successively cutting out resistances R<a> to R<e> from the motor circuit. The actuating windings of the switches R to R<5> are all connected in series, and intermediate connections are led off between each two adjacent windings to one of a pair of contacts 23, 24, arranged to be bridged by a contact 25 attached to the armature of the next preceding switch in the series. Each of the contacts 24 is connected through a pair of contacts 27, bridged by a contact 28 controlled by a solenoid I in the motor circuit, to a conductor 29 ; and this conductor 29 is connected through a pair of contacts 30, normally bridged by a contact 25 controlled by one of the switches in advarce of the one being operated, to the compensating- resistances r<1> to r<5>, which are cut out of circuit as the actuating windings are cut in. By the action of the solenoid I, the circuits of the switchactuating windings are interrupted whenever the current in the motor circuit rises above a predetermined limit. To prevent the opening of the switches which have already been operated, each of these switches, except the first, is provided with an additional set of contacts 33, 34, arranged to be closed by the bridging contact 35, whenever the switch is in its closed position, so as to establish a shunt circuit around the contacts 27.
