Patent GB-190520368-A (GB)
Title: Improvements in or relating to Single-phase Commutator Motors.
Inventor: FYNN VALERE ALFRED
Filed: 1905-10-09
Granted: 1906-10-09
Abstract: 20,368. Fynn, V. A. Oct. 9. Field magnets; motors, controlling.-With the object of improving the starting-torque and speedregulation of single-phase commutator motors, which start as repulsion motors and run in normal operation as induction motors, the features of a repulsion motor and a series motor are combined in the machine shown in Fig. 5, having repulsicn brushes R and series brushes H connected either with the same or with different windings. The field winding is divided into two parts S<1>, S<2> displaced by ninety degrees, and the speed and torque of the motor are varied, as shown in Fig. 7, by cutting in or out turns of the field winding S<2> by means of the contact-lever L, or by altering the grouping of the turns. The machine is converted into an induction motor by short-circuiting either the points 4, 6 or the points 1, 6. In Fig. 7, an auxiliary series winding S<3> is disposed on the stator co-axially with S<1> in such a way that the voltage generated therein will be added to the voltage impressed upon the motor, so that the maximum torque of the motor is increased. The winding S<3> is used to compensate the motor after the latter has been converted into an induction motor by short-circuiting the brushes H either directly or through a resistance W. The resistance W may also be used for obtaining the finer speed adjustments of the motor when working as a series machine. The compensating electromotive force may be derived from a separate transformer having its secondary winding connected in series with the stator windings and the primary winding in parallel with the mains, or it may be derived from the winding S<1>. The rotor may be supplied with current from the field circuit by means of a series transformer, either the primary or secondary of which, or both, may be short-circuited when the motor is converted into an induction motor. The windings S', S<2> may also be fed from the mains through series transformers. To reverse the motor, either the connexions of the field windings S<1>, S' are reversed, or the direction of the current through the brushes H and field winding S<2> is changed. The Provisional Specification describes also a combined repulsion and shunt motor having the armature connected in series with the winding S<3> and in parallel across the mains, with or without the interposition of a transformer.

Title: Improved Steam-engine Governor
Inventor: PROELL WILHELM
Filed: 1905-11-10
Granted: 1906-10-11
Abstract: 23,078. Proell, W. Nov. 10. Centrifugal governors. - In a shaft governor, each of the centrifugal weights moves outwards against a spring, and by means of a link a shifts an eccentric sheave e, Fig. 1, surrounding another eccentric g. The point of attachment of the spring is close to the centre of gravity of the weight, and the link a is also pinned near the same point. The purpose of this is to reduce as much as possible the reaction of the support. The link a may be replaced by the rack-and-pinion arrangement shown in Fig. 3, a roller r keeping the rack in contact with the sheave. The governor is suitable for turbines.

Patent GB-190603948-A (GB)
Title: Improvements in Air Brake Apparatus
Inventor: TURNER WALTER VICTOR
Filed: 1906-02-17
Granted: 1906-06-21
Abstract: 3948. Turner, W. V., and Wright, E. A. Feb. 17, 1905, [date applied for under Patents Act, 1901]. Brakes.-In an air-pressure brake, a part of the exhaust air escaping from the cylinders when the brakes are released-is stored up in a reservoir 6, Fig. 5, and is used again the next time the brakes are applied, or for blowing a whistle, or for other purposes. In applying this arrangement to the ordinary Westinghouse brake, the seating of the triple valve is provided with ports 24, 25, Figs. 2 and 3, in addition to the usual exhaust port 18 and brake-cylinder port 19, the port 24 being connected with the storage reservoir 6, and the port 25 with the brake cylinder through a check valve 26. The exhaust port 18 instead of being connected directly to the atmosphere is connected to a port 32 in the seating of a valve 5, Fig. 1, the brake cylinder being also connected to the valve chamber 29 of this valve by a pipe 8. Additional ports 33, 35 in the seating are connected with the atmosphere and with the storage reservoir 6 through a check valve 36. A valve 30, with a cavity 34, and operated by a piston 31, controls the connexion between the port 32 and the ports 33, 35. The piston is acted upon by a spring 37, and is exposed on one side to the pressure of the storage reservoir and on the other side to that of the brake cylinder. When the brakes are off, the valves occupy the positions shown in Fig. 1. When the brakes are applied, a cavity 27, Fig. 2, in the main slide valve of the triple valve first connects the ports 24, 25 and allows a certain amount of air to pass from the storage reservoir to the brake cylinder through the check valve 26, the air from the auxiliary reservoir being subsequently admitted through the ports 21, 19. The valves then assume the position shown in Fig. 2, the piston 31 of the valve 5 being pushed over with its valve 30 by the excess pressure in the brake cylinder over that in the storage reservoir, so that, on release of the brakes, the air passing through the exhaust port 18 of the triple valve passes first to the storage reservoir through the check valve 36 until the pressures in the brake cylinder and the storage reservoir have equalized ; the spring 37 then moves the valve 30 to connect the exhaust port to atmosphere. In a modification, shown in Fig. 7, adapted only for intercepting a portion of the exhaust air without using it again for the brakes, the exhaust from the triple valve 4 is connected to the chamber 29 of the valve 5, and the seating of this valve has a small exhaust port 33. The exhaust from the triple valve 4 first moves over the valve 30, closing the port 33 and opening the port 35, so that it can pass through the valve 36 to the storage reservoir 6. When the pressures have equalized, the port 33 is opened again, and the release of the brakes is completed. This arrangement may be employed in a straight air system, the valve 5 being connected to the exhaust port of the driver's valve instead of to the exhaust port of the triple valve.

Abstract: 27,098. Humphreys, G. H. Ward-. Nov. 28. Slipping of wheels, preventing.-A trailing wheel is mounted beneath the vehicle and is subjected to a downward pressure which increases with the amount of side.-slip. The trailer arm a, which carries a roughened wheel b, is provided with a pin c, travelling in a slot d in a bracket f pivoted to the car frame at g. Almost over the wheel b is mounted a roller h which, when side-slip occurs, engages pivoted wedges kept in the positions shown by springs k. These springs prevent shock when the device comes into operation. The inclination of the wedges may gradually decrease so as to avoid shock as the device returns to its normal position, and the outer ends have projections or stops t. Chains m, or other devices, fixed to the trailer are provided for drawing the arm a out of operation. The lower end of the slot d has preferably a dip p. The wheel b is made as large and broad as possible; to keep the corrugations clear, a comb may be provided on the bracket a. To prevent the pin c from sliding up the slot, the wedges are preferably inclined transversely, as shown at r. A spring cover bearing on the pin c may also be provided to prevent it from rattling.
