Patent GB-190303658-A (GB)
Title: Improvements in the Motors and Regulating Devices for Electrically Propelled Vehicles.
Inventor: RAWORTH JOHN SMITH
Filed: 1903-02-16
Granted: 1904-02-11
Abstract: 3658. Raworth, J. S. Feb. 16. Electric motor vehicles.-The motors on electrically-propelled vehicles have two field circuits, one b, Fig. 1, a shunt winding and the other v in series with the armature. Electric energy is returned to the line in descending gradients and the motion of the car is arrested. Reference is made to Specification No. 3657, A.D. 1903. The series windings arranged to augment the field when the motor returns current to the line, are controlled by a lever w, carried by the speed lever d, which, under normal conditions, is kept away from the lever d by the spring x, Fig. 3, thus short-circuiting the series coils v, Fig. 1. The speed is controlled by increase or decrease of the fields by resistances in series with the shunt windings b. In descending a hill, the lever d is drawn back, thus decreasing the resistance in series with the shunt windings b, and causing the motors to return a current to the line. Should the retarding action due to generating a current be insufficient, the handle w is pulled, putting the coils v in series with the armature. To prevent the handle w from being moved before the motor acts as a generator, a pin 6 is arranged to engage a portion 5 of the controller casing until the resistance is completely cut out of the shunt coil. The pin 6 is now over the recessed part 7 and out of engagement with the casing, and the handle w is capable of movement. Should the trolley leave the line, the lever j is so arranged that, when released by the lever d, it may be moved so that the armatures a are short-circuited on themselves. The handle w is also used to remove the short circuit on the series fields v. The motor now acts as a generator and as a brake. To prevent the armature from being short-circuited while there is a current in the shunt windings b, a magnetic switch 1 is placed in series with the shunt coils at A, which only closes the circuit when no current is passing through the coils. If desired, the switch may be spanned by a resistance 3, and the motors will then act as brakes immediately the power circuit is opened.

Title: Improvements in Speed Alarms or Indicators especially adapted for Vehicles
Inventor: ROUAIX GASTON
Filed: 1903-03-23
Granted: 1903-07-23
Abstract: 6708. Rouaix, G. June 25, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Speed indicators. -Centrifugal apparatus, suitable for road vehicles, indicates the speed, and sounds an alarm when it exceeds a certain limit. Rotating with the shaft o, which is driven from a wheel shaft, are two balls d. Outward motion of these causes a clutch e to slide along the shaft. By means of a forked lever g and cord passing round the pulley h, the clutch e moves the disc a, which is graduated to exhibit the speed externally. The milled button i can be set in position corresponding to three different speeds, which are shown externally on the disc b, moved by bevel-wheels m, n. For each speed for which the button i is set, a lever p determines such a position of a sliding clutch f that the rotating clutch e will engage with it when that speed is attained, and strike the bell j by means of the ratchet-wheel k and lever l. Fig. 7 shows a device for registering excess speed by means of numbers on the wheel v. Motion of the above-mentioned clutch e in the direction shown actuates the roller and lever s, so that the pawl t slips over the teeth of the ratchet-wheel u. On the return of the clutch, a spring s<1> causes the pawl to drive the ratchet-wheel and thereby move the wheel v.

Title: A New or Improved Watt-hour Meter.
Inventor: ZIEGENBERG RUDOLF
Filed: 1903-05-11
Granted: 1904-01-21
Abstract: 10,697. Ziegenberg, R. May 11. Energy meters.-In a commutator motor meter, a magnetic body m, Fig. 1, mounted on a spindle a, is magnetized by a fixed coil n and rotated by a uniform circular field produced by the coils W. The arrangement of the coils through which the current passes is shown in plan Fig. 4. The currents while acting on the magnetic body must be all centrifugal or all centripetal. It is necessary to reverse the currents in the solenoid n or in the coils W when the body m passes from I to IV and from III to II. This is effected by a commutator such as is shown in Fig. 4 of Specification No. 6102, A.D. 1903, or by the arrangement shown in Fig. 6, which is arranged to reverse the current in the coil n. A roller connected to the spindle a rolls on the continuous ring s and the divided ring c. This, owing to the potential gradient of the current between the leads l in the resistances w<1>, w<2>, has the effect of reversing the electromotive force acting on the coil n. The magnetic body may be a roller, and in this case, acts as the roller of the commutator. An auxiliary coil is used to move the body across the dead points.

Abstract: 17,938. Wlinholt, E. A. Aug. 18. Driving - mechanism. - In two-speed driving- mechanism for cycles, for high speed, a sliding bevel-wheel a is adapted to be clutched to a wheel b upon the crank axle, so that, through a sleeve i, rotation is imparted to the chain-wheel g ; in freewheeling, the wheel a is moved out of engagement with the wheel b but not sufficiently far to engage teeth c' upon a wheel c ; while, for low speed, the sliding wheel being brought to engage the horizontal wheel, motion is transmitted to the chainwheel through teeth c', c', wheel a, and sleeve i. For changing the gear, the device shown in Fig. 4 is mounted on the top tube near the handle-bar. Thus, when a pawl p engages the lowest tooth of a disc s, the high gear is in action ; on pushing up the handle m to its middle position, a cord 5 passing over a pulley below the saddle and secured to a bifurcated lever t, Fig. 3, moves the sliding wheel into its free position ; on moving the pawl to engage the uppermost tooth, the sliding wheel is brought into engagement with the wheel c. The lever t has projections or blocks received by a groove 1 in the wheel a. A spring f tends to depress the end of the lever to which the cord is attached. By the aid of a counter-nut e, the wheel b can be somewhat slid along the axle and the bearing 2 tightened.
