Title: Improvements in Hub Driving and Braking Mechanisms applicable to Cycle Wheels and like Purposes
Inventor: KEMP ROGER
Filed: 1902-11-21
Granted: 1903-10-22
Abstract: 25,580. Kemp, R. Nov. 21. Clutches; brakes.-In a combined free-wheel and back-pedalling brake mechanism for the driving-hubs of cycles and the like, the chainwheel is mounted on the end of a sleeve a, which turns on ball bearings v<2> on a fixed spindle h<1> and is separated from the hub by a ball bearing v<1>. The sleeve a is formed with a quick-threaded screw c to engage a corresponding nut d, which is formed with oppositely-directed ratchet teeth e, f on its two faces. On turning the chain-wheel in the forward direction, the nut d moves into engagement with a ratchet ring g fixed to the hub, and transmits the motion of the chain-wheel to the hub. On arresting the motion of the chainwheel, the nut d becomes disengaged again. On moving the chain-wheel backwards, the nut d moves into engagement with ratchet teeth l on a brake-operating ring k, which is mounted on a fixed sleeve h and separated from the hub by a ball bearing v. The brake may consist of a band r attached at one end to a fixed block p and arranged to be expanded against an enlarged part a' of the hub. The ring k is connected to the band r by an intermediate ring o which is moved laterally by the ring k by means of inclines or ratchet teeth m on the ring k and on the ring o. A wedgeshaped tooth s on the ring o engages an incline on the block p, and also bears against the free end of the band r, so that, when the ring o is moved laterally, the brake band is expanded. A sleeve t fixed to the ring k engages a spring u fixed to the nut d and prevents it from rotating when it is free from the ratchets g, l. The ball bearings are adjusted by means of a cone w.

Title: Improvements in Electrical Synchronism Indicating Apparatus.
Filed: 1902-11-29
Granted: 1903-11-28
Abstract: 26,386. British Thomson-Houston Co., Clinker, R. C., and Wedmore, E. B. Nov. 29. Testing.-A phase-difference indicator, applicable for synchronizing alternators, consists of a transformer having two primary coils b, c connected to the two sources of current k, l, and having opposite parts of the core a connected to any suitable magnetic indicator. The indicator may consist of a small secondary winding g on a thin core extending between opposite parts of the main core a ; the secondary winding is connected to a low-reading volt-meter h. The primary connections are such that when the applied pressures are equal and in the same phase no secondary current is produced. If the pressures are slightly out of phase, the deflection of the volt-meter indicates the amount of difference. With larger differences in phase, the thin core becomes saturated, so that the deflection increases only slowly. In the form shown, the transformer has polar projections d, e separated by an air-gap, parallel to the thin core ; in a modification, the polar projections are dispensed with, and the main core is made with a smaller central opening.

Title: Improvements in Double Universal Joints.
Inventor: WILLIAMS HARVEY DANIEL
Filed: 1903-08-26
Granted: 1903-10-22
Abstract: 18,436. Williams, H. D. Sept. 17, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Universal joints.-A double universal joint is employed for connecting two shafts, and is so arranged that uniform motion of both the shafts is obtained. The driving-shaft 1, Fig. 2, and the driven shaft 2 are each formed with a spherical head 9 to which a ring 11 is pivoted by pins 10. The rings 11 are journalled on trunnions 12 within a cylinder 3, the trunnions being arranged at rightangles to the pins 10. The exterior of the rings may be spherical to engage the interior of the cylinder so that it may carry a lubricant. A circumferential channel 14 is formed within the cylinder by means of walls 4, 5. The wall 5 may be movable and retained in place by set-screws, or it may be screwed into place. A disc 6 is mounted within the channel 14, and is provided with spherical-ended hubs or projections 7 adapted to engage sockets 13 in the ends of the shafts 1, 2, or the hubs 7 may engage blocks adapted to slide in the sockets 13 so as to obtain a surface contact. In another arrangement, projections are formed on the ends of the shafts 1, 2, and engage a cylinder or sockets on the disc. In a modification, the cylinder 17, Fig. 3, is made in two parts which fit together and form a channel 14 for the disc 6. The shafts 15, 16 are formed with spherical parts 18 to engage the open ends of the cylinder. The hubs on the disc 6 and the ends of the shafts are forked and are coupled to interposed blocks 20 by pins. By this arrangement, a uniform motion of the driving-shaft is transmitted through the joint to the driven shaft. Should the inclination of either of the shafts be altered, the mechanism adjusts itself so that the angles between the axis of the shafts and the axis of the cylinder remain equal.

Title: Means for Operating Signals upon Railway and like Engines and Vehicles
Inventor: CESAR VITAL
Filed: 1903-11-30
Granted: 1904-01-28
Abstract: 26,146. CÚsar, V., and Guarini, E., [trading as CÚsar & Guarini & Consorts]. Nov. 29, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Crossing-gate signals; indicating condition of permanent way; signalling between trains; signals on engines and trains.-The Figure shows a track section in which the circuit of the battery 2 is formed by the rails 4, and brushes 8 on the leading end of a tramcar, engine, or vehicle 5, joined by a conductor 9. The presence or absence of a current in this conductor effects, by means of the double polarized relay 10, the closing of a local circuit on the engine through the white or "line-clear" lamp 14, or the red or "danger " lamp 12. This danger signal may be due to interruption of the circuit by a key 3 at a cabin, the opening of a crossing-gate 6 having a contact in the circuit, defects in the rails, or the presence of another engine or tramcar 7, nearer to the battery and therefore short-circuiting it. The arrangement is applicable to protect coaches or the like on sidings.
Patent GB-190403365-A (GB)
Title: Improvements in and relating to Railway Switches
Inventor: SCHILHAN JANOS
Filed: 1904-02-10
Granted: 1905-02-10
Abstract: 3365. Schilhan, J. Feb. 10. Points and switches.-Relates to railway points and switches, and consists in means for preventing the movement of the switch-tongues while a train is passing, and for ensuring the passage of the train on to one or the other line if the switch is incompletely adjusted. The device for preventing the shifting of the tongues under the train comprises two press-bars 6, 7 pivotally connected by the short levers 8 to the flanges of the respective track rails and linked to the pivoted lever 10. These press-bars are arranged so that the one at the side of the track rail in use is level with it while the other one is elevated above its respective rail. The abutments 13, 14 on the lever 10 co-operate with the abutments 15, 16 on the underside of the switch tongues so as to prevent any movement of the points while a train or the like is passing over the bars 6 or 7. If a vehicle is moving from right to left in Fig. 1, and the points are incompletely adjusted, automatic adjustment is obtained by the depression of the corresponding press-bar. To prevent derailment, and ensure that a train will run into one of the track lines in case of the points being incompletely set, one of the tongues is formed at the point where the distance between the two tongues is equal to the distance between the wheel flanges on one axle, with a wedge-shaped groove 5 ascending towards the pivot so as to allow the wheel flange to pass to the inside of the tongue. A transverse groove may also be provided in the tongue at this point. The tongues must be provided with strong wedge-shaped fishplates 3, 4 to assist the wheels over the gap between the stock and tongue rails. Fig. 3 shows a modification, in which the switch tongue is cut away for a certain distance horizontally from the point, and replaced by a separate corresponding part 17 pivoted at 18. The other end of this part 17 is chamfered and abuts against a similar chamfered end formed on the rail. To prevent displacement during normal working of the tongue, the part 17 is further secured by a weak pin 19. If the switch should be incompletely adjusted, the pressure of the vehicle wheels will shear the pin 19 and rotate the part 17 inwards, the wheels then running on to the inner edge of the tongue. A further modification is shown in Figs. 5, 6, and 7 in which a cheek 20, with an inclined surface, is connected to the tongue by the pivot 21. When the tongue is in the open or half-open position, the cheek 20 rests on the rail chair 22 and guides the vehicle wheels on to the inner edge of the tongue. The chair 22 has an inclined surface, so that, when the tongue is moved into the closed position, the cheek descends by gravity into a position under the head of the rail, as shown at 20<a> in Fig. 7.

Title: Improvements in Hot-air, Steam, and Combustion Product Engines
Inventor: MEES JOSEPH
Filed: 1904-05-10
Granted: 1905-05-10
Abstract: 10,719. Mees, J. May 10. Cycles or systems of working. -The engine shown in Fig. 1 works on a two-stroke cycle and may be actuated by hot air or gas, combustion p r oducts, or live or exhaust steam. Air or exhaust steam is admitted to the crank chamber C at the end of the instroke of the piston through a series of pistoncontrolled ports (not shown). During the instroke, air or steam admitted to the cylinder trom the crank chamber through the port B at the end of the out-stroke is forced through a valve D and a hinged valve m, Fig. 4, to a pipe f leading to a heater. When working as a steam or hot-air engine, the cylinder, during the working stroke, receives a charge of superheated steam or hot air from the heater through the flap valve k and the mechanically-operated valve D, the opening of which is regulated by an adjustable cam (not shown). To allow the valve D to open automatically during the compression stroke, the operating-rod is divided as shown in Fig. 1. The cylinder exhaust takes place through ports F. When using live steam in the cylinder, the exhaust may be passed into the crank chamber and be returned to the steam generator by the piston. If preferred, the compression of the motive fluids may take place in an independent cylinder.

Abstract: 14,721. Cole, T. H. June 30. Gas and like engines.-Air is drawn or forced through the liquid used to cool the cylinder of an internal-combustion engine in order to keep its temperature low. The liquid is contained in a tank A placed above, and in free communication with, the cylinder jacket. Air enters at the bottom through the pipe D, which is arranged either at the side, as in Fig. 1, or through the centre of the tank, as in Fig. 3. A finely-perforated plate E ensures the equal distribution of the incoming air, and a similar plate F, Fig. 1, supported by floats f, minimizes the agitation of the surface of the liquid as the air leaves it. Other perforated plates J, Fig. 1, preferably of a conical form, are placed in the upper part of the vessel, and a loaded valve G and a pressure gauge I are fitted at its top. The apparatus shown in Fig. 3 is provided in its upper part with a chamber N for catching and returning liquid which may be carried by the escaping air. At the top of the chamber are perforated plates P, to the uppermost of which are fixed baffle-plates Q interposed between similar plates Q<1> secured to the top of the vessel A. The escaping air passes up outside the chamber N and over the baffles to the outlet m, and the liquid it contains, collecting in the chamber, passes back through apertures q. The vessel A may be formed integral with the cooling-jacket, as shown in Fig. 4 ; in this case, the air is delivered at the bottom of the jacket through a perforated pipe S arranged so as to distribute the air equally. A perforated plate E, formed with a downwardly projecting central aperture e, is placed at the bottom of the vessel, and the air escapes, either through a perforated pipe K, as shown, or through either of the arrangements described in connection with the apparatus shown in Figs. 1 and 3.
