Patent GB-190219283-A (GB)
Title: Improvements in Electric Transmission and Controlling Gear.
Inventor: JOHNSTON JOHN
Filed: 1902-09-02
Granted: 1903-08-27
Abstract: 19,283. Johnston, J., and Dobbs, A. E. Sept. 2. Dynamos and motors combined for transmitting power.-Relates to the transmission of power by electromagnetic means between two co-axial shafts, in self-propelled vehicles, the same also acting as a change-speed gear. Fig. 2 shows a sectional elevation, and Fig. 1 a diagrammatic view of the arrangement. The armature and commutator of a dynamo are attached to the motor shaft b, while the field magnets and brushes e are fixed to the other shaft a. A regulating-resistance h is placed in series with the field windings, the current being collected by slip-rings i, j. As the armature d revolves, it drags the field magnets round it, and so drives the vehicle. The speed of the field magnets is necessarily less than that of the armature. When the resistance to motion increases, the magnets slow down, causing more lines of force to be cut, and throwing a heavier load on the motor. The vehicle thus moves slowly against the higher resistance. If the resistance is less, the magnets follow the armature mure quickly, and the load on the motor is lighter. The speed may also be varied as required by the resistance h.

Title: Improvements in Valves.
Inventor: KOEHLER GEORG WILHELM
Filed: 1903-12-09
Granted: 1904-02-18
Abstract: 26,977. Koehler, G. W. Dec. 9. Lift valves; actuating v a l v e s; valves closing with rush of fluid; spindles; tampering with valves and cocks, preventing.- Relates to a stop valve of the screwdown type which closes automatically in the event of a burst occurring in the exit end. The main valve c, Fig. 1, fits loosely in the casing a, closing the fluid - way when resting on its seat. An annular valve d is pressed by the weak spring e on to the main valve, allowing the chamber above the latter to contain steam at boiler pressure. The main spindle g, h is hollow and is operated by a bandwheel f in the usual way. A spindle m passes loosely through it, and is connected to it by anadjustablespring which is enclosed in a casing t to prevent tampering with the adjustment. The end of the spindle m closes a passage n through the main valve. The spindle also has collars q, p, the former of which is pressed against the end of the spindle g partly by fluid pressure and partly by the spring, while the latter engages with a sleeve o on the main valve when the spindle has been raised a certain distance. On actuating the hand-wheel, the hole n is first opened, thus equalizing the pressure on both sides of the main valve. As the spindle h rises, the spindle m follows it and opens the main valve when the collar p and the sleeve o come into contact. The spring is adjusted so that its tension together with the fluid pressure on the collar q are just sufficient to balance the weight of the main valve. If a burst occurs in the outlet side of the main valve, the latter is forced on to its seat by the fluid pressure. If the steam pressure is high, the spring r is adjusted so as to act in opposition to the pressure on the collar q so that the latter shall not be pressed too firmly against the end of the spindle h. The spindle g enters the valve casing through a stuffing-box having an outer flange i and a gland k. The flange i has knife-edge projections which engage with corresponding notches in the gland, and prevent the spindle from jamming should the nuts in the studs l be screwed up unequally.
