Patent GB-190208557-A (GB)
Title: Improvements in Electric Motor Control Systems.
Filed: 1902-04-12
Granted: 1903-01-22
Abstract: 8557. British Thomson-Houston Co., [Linn, J. B.]. April 12. Electric locomotives and motor vehicles.-Relates to master-control systems for electric motors, in which each of the motor controllers is of the separately-actuated contact type. 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 predetermined intervals of time, which may be adjusted once for all in any particular system, or may be made to depend upon certain predetermined conditions. 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 throughout the train by a set of three wires 1, 2, and 3. M<1> and M<2> 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'. The motor controller D comprises a series of electromagnetic switches, viz., a main-circuit closer T<1>, a series switch S, two parallel switches P and P<1>, 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 21, 22, arranged to be bridged by a contact 23 attached to the armature of the next preceding switch in the series. Each of the contacts 22 is connected to one of a pair of contacts 25, normally bridged by a contact 23, controlled by one of the switches in advance of the one being operated, the circuit being completed through compensating resistances r<1> to r<5>, arranged to be cut out of circuit as the actuating windings are thrown in. To provide for a sufficient interval between the operation of one switch and that of the next in the series, they may all be fitted with dash-pots or equivalent retarding - devices. A modification of the system is described in which the switches are arranged in two parallel sets, for the purpose of keeping down the resistance of the control circuits. In this case, four train wires are required instead of three. Reference is made to Specification No. 8558, A.D. 1902, which describes a modification of the system.

Granted: 1904-09-29
Abstract: 9709. Portsmouth, W. April 28. Safety wheels and supports.-Safety wheels for bicycles are adapted to be raised or lowered by the rider, and means are provided for supporting the machine with its wheels clear of the ground. To lower the wheels D, the operation of a lever F actuates a rod G which is connected by a ball joint to an arm H upon a spindle B, so that this spindle, and with it the wheels D, is depressed. During this motion, however, owing to the engagement of a pin P with a slot S, the spindle is turned, so that a rack K is brought into engagement with h a spring - pressed pawl L<1> while the axle of the wheels is carried round from the raised position shown in dotted lines to the transverse operating position, shown in full lines. The pawl retains the device depressed. To return the parts to their normal position, the depression of a lever M actuates a wire or the like N connected to the pawl, which, thus drawn back, leaves the spindle free to be raised by the expansion of a spring. The rod G is received by a sleeve J, and, to support the machine with one road wheel off the ground, the bicycle is lifted and the wheels D depressed beyond their normal operating position by pushing down the rod G by means of a projection R. To support the machine entirely clear of the ground, a stay D<1> on the rear-wheel axle is now turned down, as shown in dotted lines.
