Title: Improvements in Electric Train Control Systems.
Filed: 1899-10-30
Granted: 1900-01-27
Abstract: 21,657. British Thomson-Houston Co., [Barry, C. E.]. Oct. 30. Electric locomotives and motor vehicles.- Relates to master controller systems for electrically - propelled trains in which the motor controllers are operated by a pilot motor. A throttle shown as a solenoid and plunger switch D is used to cut off the current to the pilot motor E when it has reached the desired position, but this throttle is short-circuited by contacts H on the motor controller B so that it cannot act unless that controller is in the desired position. The throttle is wound with two coils, one in series with the main motors M<1>, M<2> so as to stop the controller if those motors are receiving too much current, and the other directly supplied through the master controller A, which is of the resistance and regulating type, so that the speed of the pilot motor may be controlled. An electromagnetic brake C<2> is used, instead of ratchet or similar gear, to hold the motor controller in the desired position. The plunger switches D<1>, D<2>, D<3> are used to complete and reverse the pilot motor circuits. To prevent damage to the motors M, if the controller is in the full multiple position after a temporary cessation of current, the switch D<4> is introduced to render it impossible to throw on the current until the controller B has been returned to its off position.

Patent GB-190103183-A (GB)
Title: An Improved Rudder Brake
Inventor: GRENFELL JOHN SAMUEL WALTERS
Filed: 1901-02-14
Granted: 1901-09-28
Abstract: 3183. Grenfell, J. S. W. Feb. 14. Steering-gear; rudders.-Relates to a brake for holding the rudder stationary, should the steering- engine break down or the steering- chains fail, The brake may be applied automatically or by hand. On the rudder-head is secured a quadrant B, having a lower smaller rim to receive the steering-chains, and an upper rim B<2> to receive the brake blocks D. Each is secured to a box-like frame D', sliding in guides, and moved towards or away from the quadrant by a cam E on a vertical spindle. To the upper end of this spindle is hinged an arm F, which normally rests on a crank G<1> on a shaft G. At the centre of this shaft is a projection G<2>, which engages a lever H hinged on the shaft G and resting on the collar J<1> of an ordinary centrifugal governor. The governor is frictionally driven from the rim B<2> by rollers K and J<2>. The rollers K, as shown in Fig. 1, are carried by levers, operated by screw or other gear to throw the said rollers out of contact when required. In fine weather, when the steering-gear is not liable to breakage, the governor may be thrown out of gear. Should the gear fail, however, and the rudder be left free to be thrown violently from side to side by heavy seas, a rapid movement of the rim B<2> causes the governor to raise the lever H and rotate the shaft G. The cranks are thus moved clear of the arms F, which drop on to the rim B<2> between the studs B<3>. The next movement of the quadrant rocks the arms F and their cams, and applies the brake blocks. The ends of the arms F are rounded, so as to be thrown clear of the studs, and thus a backward movement of the quadrant does not take off the brakes. By means of a lever 0, the brakes can be applied by hand from the bridge or other place. After repairs have been effected, the parts are replaced by hand.
