Title: Improvements in or relating to Hoists, Lifts and the like.
Inventor: WRIGHT WALLACE
Filed: 1901-12-06
Granted: 1902-11-06
Abstract: 24,894. Wright, W., Hobson, H. W., Carryer, C. B., and Buswell. A. C. Dec. 6. Lifts.-Relates to well doors for hoists, lifts, and the like. Entrance to the well is normally stopped by a bar, which must be raised to the top of the opening in order to allow a passenger to enter or leave the cage. The bar, when thus raised, is retained by a catch, which is released, when the cage. departs, by a projection on the cage, thus allowing the bar to drop to its normal position. The catch may consist of a hook 9, and be operated from a projection 18 on the cage through a bolt 13 having a curved head 16. In modifications, the catch is directly engaged by the projection 18, or the bolt 13 is formed with a hook to serve as catch. The bar is preferably fitted with counterweights, and runs in guides 2.

Title: Governing Device for Steam-turbines.
Inventor: STUMPF JOHANN
Filed: 1901-12-12
Granted: 1902-12-11
Abstract: 25,414. Stumpf, J. Dec. 12. Steam &c. turbines.-Relates to governing - devices for steam or gas turbines. The ring of admission nozzles b, Fig. 1, is divided into groups I, II, III by partitions A. The steam pipe g opens into a chamber d having ports i opening on to the groups of nozzles II, III, these ports being normally closed by spring- pressed valves k. The nozzles in the group I open into a second chamber e connected to the steam pipe by a pipe h controlled by a throttle valve m. The throttle valve is connected to a governor R, so that it opens when the turbine speed is too great, instead of closing as is usually the case. When steam is admitted to the turbine, it enters the channel d, raises the valves k, and, passing through the groups of nozzles II, III, rotates the turbine. If the speed is too great, the throttle valve opens and admits steam to the chamber e, so that the valves k close. The group of nozzles I are arranged to run the turbine without any load. By varying the valve springs l, or the size of the valves, they may be caused to close at different speeds. In a modification, a double piston valve is used. Each nozzle may be controlled by a valve k, Fig. 4, connected to a piston r in a cylinder u which is in communication with the governor-controlled chamber e. The piston device may be arranged so that the throttle valve acts in the normal, and not in the reversed manner mentioned above. In a modification, adapted to control one nozzle or a group of nozzles, two governor-controlled chambers.are respectively connected to the upper and lower sides of the valve-operating piston.

Granted: 1902-04-24
Abstract: 6854. Newton, P. A., [Bliss Electric Car Lighting Co.]. March 20. Distributing lighting, systems of ; regulating; switches.-Relates to a system of distribution comprising a primary generator, such as a dynamo driven by a car axle, a receiving-circuit, such as a storage battery &c., and means under the control of the receiving-circuit to reduce the charging- effect of the generator when the circuit is charged. Means are also provided under the control of the driving-mechanism of the generator for automatically restoring the generator to its normal operative position. The Figure shows an arrangement adapted for the lighting of railway vehicles. A is the generator driven from the car axle ; C is an electromagnet switch for connecting or disconnecting the generator to or from the storage battery D and lamp E, according to its potential ; F is an electromagnetic arrangement for reducing the energy supplied by the generator when the battery D is fully charged. It operates by breaking the self-exciting field coil a<5> at the mercury cups, and connecting the coil a<5> with the battery through a resistance 12 ; at the same time the switch C is opened and the battery supplies the lamps. When the speed of the generater drops, the core f of the solenoid falls, again closing the field circuit and enabling the battery to be re-charged. The connections and resistances may be varied, so that the generator may still supply the lamps after the battery is charged, but without over-charging the battery.

Title: Improvements in Electric Transformers.
Filed: 1902-06-17
Granted: 1903-06-11
Abstract: 13,734. British Thomson-Houston Co., [Moody, W. S.]. June 17. Transformers.-Relates to arrangements of windings for providing automatic regulation under varying conditions of load and for interchangeable connection on different supply voltages, which embody the same generic idea as those described in Specification No. 29,586, A.D. 1897, and consists in dividing the secondary into, for example, four parts, two on each part of the core, and in connecting each of the two parts on one leg of the coil in multiple with the other two parts on the other leg. The arrangements also permit of connecting all the coils on one leg in series with the coils on the other leg. In all cases, the loaded secondary is disposed on both legs of the core, and consequently it prevents unequal magnetization of the two legs of the core, which would establish consequent poles in the end pieces and shunt a part of the flux as leakage across the air space between the legs. The primary winding is preferably mounted outside the secondary, and the parts of the secondary are preferably mounted concentrically with respect to each other. Fig. 1 shows a suitable arrangement of the primary coils P, and Fig. 6 the arrangement of the inner and outer secondary coils IS, OS, the primary coils being omitted. The secondary leads are carried through a connection board B, Fig. 4, S<1>, S<2> being the start and finish of the left-hand outer coil OS, S<5>, S<6> of the right-hand outer coil OS, and S<3>, S<4> and S<7>, S<8> being the corresponding ends of the inner coils IS. By suitably connecting the coils in multiple, as in Fig. 6, partly in multiple and partly in series, or wholly in series, voltages in the proportion of 1, 2, and 4 are obtained. Fig. 9 shows an arrangement in which one coil on one leg is in multiple with a coil on the other leg across one side of a three-wire system, while the other coil on the first leg is in multiple with the other coil on the second leg across the other side of the three-wire system. In a modification of the last arrangement, each secondary is composed of one coil only, which is connected at its middle point with the neutral line of the three-wire system. Each of these secondaries is wound throughout its length with a double conductor.

Title: Improvements in Fuzes for Projectiles.
Inventor: BARLOW HILARIO WILLIAM WELLESL
Filed: 1903-01-19
Granted: 1903-11-19
Abstract: 1323. Barlow, H. W. W., and Charlesworth, W. Jan. 19. Fuzes for projectiles; detonators.-The nose fuze is controlled by a tube, which on the firing of the gun is projected forwards, thereby igniting a time fuze, releasing a percussion fuze, and opening communication between the charge in the fuze and the bursting-charge in the projectile. Fig. 2 shows one form of fuze. A time fuze, communicating with a powder charge P, is carried by rings H, H<1>, and is regulated by turning the lower ring H<1>. A plunger B is connected by an axial tube A with a plate A' at the rear of the projectile, so that the firing of the gun shears the retaining-flanges C, C' of the plunger B, and forces the plunger B forwards, thereby firing a detonator D at its front end, the flash from the detonator passing through a passage F and powder charge G to the time fuze. A shoulder on the plunger B, which normally prevents the action of the percussion fuze E, simultaneously releases it, so that the fuze E can act in opposition to springs R if the projectile strikes an object. The flame is prevented by the plunger B from passing from the charge P through the powder Z in the tube A to the bursting-charge Z<1>, except when the plunger is forced forwards. In a modification, the time-fuze composition K, Fig. 4, is contained in external helical grooves in the fuze body N, and communicates through a hole L and powder charges M, M<1> with the powder Z in the tube A, when the plunger B is forced forwards. Apiece 0, fixed to the cap S of the projectile and carrying the percussion fuze J, a punch F, and the head C of the plunger, engages with an internal screw in the body N, and the head C engages with a double thread of the same pitch on the plunger B, so that the fuze is regulated by turning the cap S, and thereby bringing the punch F to any position. When the plunger is forced forwards, the head C, by striking against an inclined portion of the punch F, forces it outwards, and causes it to perforate the body N, so that the flash from the detonator can be conveyed by the powder charge in the punch and the perforation to the composition K.

Title: Improvements in Fluid Pressure Brake Apparatus for Railway and like Vehicles
Filed: 1903-07-07
Granted: 1904-05-12
Abstract: 15,036. Westinghouse Brake Co., [Ivanoff, S. P.]. July 7. Brakes. - A graduated release of the fluidpressure brakes of railway and like vehicles is obtained by means of the spring-pressed diaphragm valve shown in Fig. 1. The casing 1 is divided internally into three chambers by diaphragms 2, 3 connected together by a support 4, and the three chambers 9, 7, 11 communicate respectively with the train pipe 10 or the auxiliary reservoir, the brake cylinder 8 or the release port of the triple valve, and the orifice 12 leading to the atmosphere. When the brakes are fully released, the train-pipe pressure in the chamber 9 is sufficient to depress the diaphragms against the action of the adjustable spring 15, and the valve 14 is thus held open to give communication between the chambers 8, 11 through the passage 13. When the train-pipe pressure is reduced to apply the brakes, the diaphragms are raised by the spring 15 and the valve 14 is closed, and a graduated release of the brakes can be obtained by gradually increasing the train-pipe pressure, the open and closed positions of the valve 14 being controlled by the positions of the diaphragms 2, 3 which are dependent on the train-pipe pressure, the brakecylinder pressure, and the spring 15. In the application to the ordinary triple valve shown in Fig. 2, the chamber 9 communicates with the train pipe 26 and with the space under the piston 23, and the chamber 7 communicates with the exhaust port through a passage (not shown), in which is a cock for enabling the gradual-release mechanism to be thrown out of action. The connections 24, 25 lead respectively to the brake cylinder and the auxiliary reservoir.

Title: Improvements in Pulsating Pumps.
Inventor: FOX HENRY JOHN
Filed: 1903-07-22
Granted: 1904-05-12
Abstract: 16,216. Fox, H. J. July 22. Direct steam-pressure apparatus; vacuum apparatus.-Relates to improvements in pumps in which the raising of water is effected by the formation, alternately, of a vacuum and a pressure in excess of that of the atmosphere in a chamber, which, in its lower portion, is in communication through a non-return suction valve with a lowlying source of water supply and, at its upper end, is connected to a steam-supply pipe, there being at this part a valve, which automatically opens when the chamber is filled with water and closes when the water has been displaced by steam and ejected through a non-delivery valve. Fig. 1 is a section of the pump along the line 1-1 of Fig. 2, and Fig. 2 a section along the line 2-2 of Fig. 1. The converging vessels h, placed within the chambers a, lead to the delivery valves d and are made of thin sheet metal, which may be corrugated to increase the surface. When the water in the upper part of the chamber is forced out through the tube h by steam admitted through the valve f, the portion below the level i, i remains, and the steam within the tube h is readily condensed. The tube h also serves to still the water entering the chamber. The rapid condensation is still further brought about by the injection of cold water through the tube k from a cylinder j in communication with both chambers and having an easy-fitting piston, which is actuated, according to the difference in pressure between the two chambers, every time the valve f moves. The motion of this valve is automatic, as, when one chamber has filled with water, a vacuum is just being produced in the other, and the valve travels over accordingly. To regulate the amount of steam admitted each time, the seating g<1> of the valve can be screwed in or out. The cover u can also be raised from time to time so as still to keep the ball f in position after it has worn.
