Title: Improvements in Means for Starting Alternating Current Dynamo-electric Machines.
Filed: 1901-12-21
Granted: 1902-04-10
Abstract: 26,135. British Thomson-Houston Co., [Woodbridge, J. E.]. Dec. 21. Converting alternating and direct currents transformers.-In starting rotary converters or the like, means are employed whereby an electromotive force of gradually-increasing frequency may be impressed upon the machine, and whereby the field of the machine may be excited by a direct current of practically-constant electromotive force. The rotary converter 1 is supplied from the mains 2, 3, 4 through a step-down transformer 5. Before connecting it directly to the transformer by the switches 6, 7, 8, it is brought up to synchronism by a frequencychanger 9, similar in construction to an induction motor and having mounted on its shaft the armature 15 of a small series-wound direct-current generator. The frequency-changer is first brought up to speed by short-circuiting its induced member through the switch 14 and inter-connected contacts 20. It is then caused to impress a current of very low frequency on the rotary converter, while the armature 15 supplies the field 16 with direct current of the required electromotive force. By means of a brake 19, the speed of the frequencychanger is then gradually reduced, whereby the frequency of the current supplied by it to the rotary converter is gradually increased. When synchronism is attained, the armature 15 is shortcircuited and, after the necessary phase adjustment, the rotary converter is switched on.

Title: Improvements in or relating to Bicycle Stands.
Inventor: BROWNE EPHRAIM HENRY
Filed: 1902-11-14
Granted: 1903-09-17
Abstract: 25,029. Browne, E. H. Nov. 14. Supports.-A b i c y c l e stand comprises a slotted tube C from which legs D, pivotally mounted in a slot at the bottom of a sliding spindle E, are adapted to slide out and support the machine. The tube C may be socketed, or fixed by a set-screw or by brazing, in the top bar and downward diagonal bar, but, to suit the varying angles of cycle frames when ordinary double clips are used, the clip of the frame should be connected by a loose rivet or the like to that of the stand. To use the stand, the set-screw K engaging the spindle E is slightly unscrewed and the handle F is brought out from a horizontal side slot m to a central long slot, down which it is pressed. The legs slide ont parallel, until projections s engage and ride on a pair of plates P, and are finally held by abutments q, when the legs bear against the cross-pins r. The handle is then turned into the side slot n, and the bicycle is supported. The tube C preferably turns stiffly in its attaching-sockets, so that the plates P may be turned clear of the cranks when the stand is not being used. Instead of using rigid abutment plates &c., the legs may be linked to a slotted block sliding in the tube and adapted to abut against a second fixed block.

Title: Improvements in and relating to Sighting Arrangements for Heavy Ordnance
Inventor: GRENFELL HUBERT HENRY
Filed: 1903-02-02
Granted: 1903-11-12
Abstract: 2460. Grenfell, H. H. Feb. 2. Methods of sighting; mountings.-Relates to the sighting-arrangements for heavy power-actuated ordnance, and provides hydraulic apparatus whereby the gun can be adjusted for range without interfering with the sights. Fig. 1 shows a side elevation, and Fig. 3 a sectional plan of one form of construction. The hydraulic cylinder E carries a hollow plunger D provided with a piston F and rod G. Pipes M, N control the liquid to the cylinder E to move the plunger D and piston-rod G simultaneously, and pipes H, J control the liquid to the hollow plunger D, to move the piston F and piston-rod G independently of the plunger. The rod G is connected to the gun slide C, and effects the elevating of the gun. A rod O, connected to the plunger D, acts through gearing upon the rod U, which moves the sight bar V so that it remains parallel to the gun axis whenever the plunger D is operated to change the elevation of the gun. When, however, the piston F is operated, the gun changes its elevation without moving the sight bar, the range being indicated on the dial c by a rod b connected by gearing with the rack W on the gun slide. In modifications, (1) the plunger D is formed of two discs, connected by distance rods, which slide through the inner piston F ; (2) the sight bar is connected by the rod U to an arm, pivoted to the trunnion axis and actuated through gearing from a differential train of wheels, which is controlled from the two hydraulic cylinders ; and (3) the internal and external hydraulic cylinders are replaced by two independent cylinders, which are either arranged side by side with their piston-rods connected by a slotted link coupled centrally to the elevating-rod G, or are arranged tandem-fashion, the front one being mounted on a slide, which is moved by the rear one.

Title: Improvements in Steam Generators.
Inventor: GLOVER LEONARD
Filed: 1903-02-19
Granted: 1903-10-29
Abstract: 3896. Glover, L., Glover, C., and Crowther, D. Feb. 19. Water-tube boilers; stays and staying. - Relates to a water - tube boiler, in which the headers are formed by plates connected together by H or Z girders side by side, the flanges being riveted to the plates. The method of staying is applicable generally to opposing flat surfaces of other forms of boilers, such as, for instance, the fireboxes of locomotive boilers. Fig. 4 is a section on line A-A of Fig. 1, and Figs. 3 and 5 are corresponding sections of modifications. The girders uniting the plates of the headers are shown at f, f<1>. The holes for the tubes and plugs are made through the flanges of the girders, the two lowest rows of tubes being screwed into the flanges and acting as tie-bars. The plates of the headers are continued upwards, and connected to the steam drum i by means of angle-ironsj, and tied together close to this connection by means of short girders k, l. This connection serves to hold together the top and bottom parts of the steam drum, which may be in separate pieces, the openings to the headers being in this case longitudinal slots. The curved portions from k to f, and from l to f<1>, readily give to the expansion and contraction of the tubes without leakage. The lower ends of the header plates are connected together and the bottoms of the headers closed by H-girders n. The vertical girders do not reach to the bottom of the channel in the girders n, so that free communication exists between the compartments into which the headers are divided by the girders f, f<1>. Fig. 3 shows the construction when girders f and double Z-bars m are used, the bars m being riveted to the header plates. Fig. 5 is a case in which Z-bars f only are used.

Granted: 1904-02-04
Abstract: 7382. Knoeferl, F. March 30. Tickets, issuing.- The tickets are contained singly in compartments i upon a rotary ring f on an annular shelf g, and are blown out one at a time, through an aperture k under a hood m, by puffs of air from a cylinder b containing a piston c, which may be arranged horizontally instead of vertically. The mechanism is contained in a drum-casing a at the centre of the main casing e, and this drum and the lid l are removed together in order to fill the compartments. The rotary ring being furnished with pins o is turned one compartment at a time by means of a sliding bar p bearing a pawl n and a rib u to pass between them ; a correcting-pawl t is also provided. The sliding bar is connected by a cross-piece q to the piston-rod c<2> and both are operated by a pushrod d with a returning-spring, but the piston only after the pawl has driven the ring. In the horizontal arrangement, the sliding bar and push-rod are combined in one, and operated by compressed air. The apparatus being, advantageously, coinfreed, the coin x disengages a pawl v from notches w in the push-rod, and drops away, when a bar y moving with the push-rod is clear of the pawl, or when a recess in the push-rod registers with it. In the horizontal arrangement, the coin, weighting a lever, may open a valve between a reservoir of compressed air and a small cylinder from which the push-rod is driven. When the rotary ring has made a complete revolution, a long pin on it encounters a lever, which sets a shutter across the coin slit.

Abstract: 14,529. Smith, L. L. June 30. Vapour burners.-Relates to an apparatus for generating and burning gas or vapour and utilizing the heat thereof. Inflammable gas obtained from oil and water is generated and burnt in the apparatus shown in Fig. 1. This consists of a coil of pipes 5, preferably rectangular, connected by a valve 7 with a water main 6. Within this is a second coil 8 through which pass three small pipes, one 9 of which is connected with the coil 5, and the others 10, 11 with tanks or the like 12, 13. One of these tanks may contain oil, and the other may contain a chemical solution or compressed air, or may be dispensed with. In the three upper coils of the pipe 8, the pipes 9, 10, 11 are perforated, and the coil is connected at the top with a third coil 16 perforated on each side. The coil 5 is filled with water from the main 6. The water is then admitted to the coil 8 by opening a valve 23, and at the same time oil is admitted from one of the pipes 10, 11. A little oil is poured into the coil 16 through a funnel 21 and escapes through the perforations and is caught by an asbestos or like strip 18. This oil, being lighted, heats the coil 8 and the pipes 9, 10, 11 and vaporizes the oil and water they contain. The vapour escapes through the perforations in the upper parts of the pipes 9, 10, 11 and passes into the coil 16, where it is burnt. Hot water can be drawn from a tap 22, and the heat of the burning gas may be utilized in various ways. Air or other material may be admitted by one of the pipes 10, 11, and material other than oil may be used for making the gas.

Title: Improvements in Couplings for Railway Vehicles.
Inventor: NOVAK EUGEN
Filed: 1903-07-29
Granted: 1904-07-29
Abstract: 16,673. Novßk, E. July 29. Couplings, automatic and non-automatic.-To enable railway vehicles fitted with automatic couplings to be coupled with such as have screw couplings, the buffer head of the former is brought to the level of the latter and either coupling may be used. The automatic coupling 7 is fixed by a key or wedge 8 on the forked arm 2, which is pivoted to the draw-bar, the draw-bar being slotted to receive a tension device comprising a spring 4 and a rod 19. A pin 5 retains the coupling in the horizontal position, Fig. 1, or the vertical position, Fig. 3. To connect with a vehicle having a screw coupling, the automatic coupling is placed vertically and the screw coupling 6 is available. When the vehicle to be coupled has an automatic coupling, the pin 5 is removed from the arm 2 and the slot of an arm 9, the head is brought to the horizontal position by the aid of the tension device, and is then again fixed by the pin, which is now passed through the draw-hooks. The approaching claw, engaging the arm 16, causes a stop 20 to push back a locking pawl or bar 12, which, then pressed out by a spring, shown in Fig. 1, holds the stop in the position shown in Fig. 2, and the claws are retained coupled. In uncoupling, turning a crank 14 causes a chain 13, connected to a roller 15, to actuate the pawl and so release the claw arm. To retain the crank in position, its shaft may be displaced so that a toothed wheel carried thereby is brought into engagement with a corresponding sleeve. The pin 5 is retained in position by two leaf springs on its sides.
