Title: Improvements in or relating to Railway Signalling Apparatus.
Inventor: DEAKIN WILLIAM HENRY
Filed: 1901-07-24
Granted: 1902-05-01
Abstract: 15,065. Deakin, W. H. July 24. Semaphore & c . signals ; signalling &c. between trains ; contacts, mechanic a l -Relates to means for putting the signals to ' danger' automatically by a passing engine or train, the movement to 'line 'clear' being effected by the ordinary signal lever. The draught connection 7 between the signal lever 8 and the balance lever on the signal post is carried round a roller 6 on one arm of the counterweighted three-armed lever 4, another arm of which is connected by a rod 10 to the controlling- lever 11, adapted to engage the end of the treadlelever 13. The counterweight 9a on the balance lever is sufficient to overcome the counterweight 4<a> on the lever 4, when both levers are free. A stop, which may be adjustable, on the short end 13<a> of the lever 13 is engaged by a bracket 16 fixed to one of the ordinary rails 2. In the normal position, as shown, the lever 11 is prevented from moving, so that, when the lever 8 is pulled, the signal is lowered. When an engine or vehicle passes over the rail 2 which carries the bracket 16, the depression of the rail causes the bracket to actuate the lever 13 and release the lever 11, the signal being then returned to 'danger' by the counterweight 9<a>. When the lever 8 is put back, the connection 7 is slackened, the lever 11 is returned by the counterweight 4<a>, and the lever 13 falls into its normal position, locking the lever 11. The supporting-plate 14 of the lever 13 &c. is provided with suitable guide for the levers, and the mechanism may be protected by a sheet-metal cover. To prevent the entrance of stones or other obstructions under the lever 13, a sliding plate or shutter is mounted in guides on the plate 14, and is operated by the lever 11. In a modification the roller 6 for the draught connection is mounted on a third arm on the lever 11 instead of on the lever 4.

Title: Improvements in Automatic Electric Brakes for Railway and Tramway Vehicles.
Filed: 1902-02-19
Granted: 1903-02-12
Abstract: 4271. Lake, H. H., [Invention Developing Co.]. Feb. 19. Brakes.-One of the axles of the vehicle has an electromagnetic clutch, which, when energized, operates the rigging and sets the brake blocks, while a governing-device is fitted to each axle. On the axle 1 is an electromagnetic clutch 12 geared to the shaft 14 carrying one end of a chain 15, the other end of which is attached to the lever 7 connected to the brake beams 5, 6 and to the hand-wheel 10. After the brakes are set by electricity, the clutch 12 may be demagnetized, the blocks being held " on " by the hydraulic lock 33, which comprises a cylinder containing a piston fitted with a non- return valve and with a rod 35 attached to the lever 7. The ends of the cylinder aro connected by a pipe 37 controlled by an electrically or hand operated valve 38, so that the brakes may be moderated or released at will. The clutch 12, Fig. 3, comprises an armature 17 keyed to the axle 1 and surrounded by a loose field magnet 18, which rotates when current is passed through the windings 19. In the form shown in Fig. 5, on closing the circuit, the poles 20 carried by the loose sleeve 18 adhere to the plate 26, which is separated from them by the springs 27 when the current ceases. Fig. 8 shows a ratchet device and hydraulic lock for combined electric and band brakes, while Fig. 10 shows a spring push 54 for opening the valve 38 by foot. The operation of the clutch 12 and the valve 38 may be controlled by one spring handle 58, Fig. 11, having a blade 61 which may engage successively with one of the plates 64, 65, 66, and so cut in one or more sections of the battery 70, or, by depressing the pin 62, the blade bridges the blocks 68, 69 and current from the battery 73 energizes the magnet 41 of the valve 38 and releases the hydraulic lock. Maximum and minimum speed circuit closers or governors are fitted to the axles 2, 1 respectively, and comprise sliding sleeves controlled by weighted arms. On applying the brakes, the axle 1, which is slowed down more rapidly than the axle 2, reaches its critical speed, and the gap 86, Fig. 17, is closed and the magnet 41 partially releases the brake. As soon as the speed of the vehicle or train is reduced to the critical speed of the axle 2, the gap 83 is opened, and subsequent closing of the gap 86 fails to release the brakes. Breaks 95. 96 are fitted in the circuit of the clutch 12 for the purpose of opening the energizing-circuit when the governors produce partial release. The brakes may be applied from any vehicle in a train. Fig. 18 shows an electric coupling, which is normally locked by the hooks 112, and the brake-clutch circuit wires 72, 91 on each vehicle are connected by the plugs and sockets shown, the breaks 110, 111 being closed. When such a coupling parts, the springs 105 urge the plugs 99, 102 against the rings 106, 107, and the wires 72, 91 are joined by the closing of the branches 108, 109.

Title: Improvements in Power-transmitting Ropes.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1902-11-26
Granted: 1903-10-01
Abstract: 26,046. Carolan, E. A., [General Electric Co.]. Nov. 26. Rope gearing.-Ropes or belts are protected from wear, and are adapted to give a positive engagement with the pulleys to avoid slipping. On the rope, which is preferably a wire rope and is composed of any desired number of strands, are threaded flat washers 3, Fig. 1, of any suitable material, washers 4 of larger diameter being inserted at regular intervals to form regularlyrecurring projections which engage in recesses in the pulley. Instead of being flat, the washers may be dished and alternated in position so as to exert a spring action, thus taking up lost space and making the belt more flexible. The smaller washers may be replaced by closely-coiled helical springs abutting at each end against the larger buttons or washers. Some of the buttons may be in halves riveted together. Small flat washers may be grouped with large dished washers, set with their concave sides facing to give spring action. Fig. 8 shows the protectors shaped as balls 15, 16 of different sizes, some being made in halves held by rivets 17. Instead of connecting the ends of the rope by splicing, they may be connected, as shown in Fig. 5, by soldering them into sockets 9 of similar hooked couplings 10, which, after being engaged, are held by a band 11 in a groove 12.

Abstract: 2372. Eaton, E., Pfeifer, W., and Briggs, C. H. Jan. 31. Moving-beater a pparatus; moving-container apparatus.- Relates to apparatus for slaking lime, mixing it with sand &c., and manufacturing blocks &c. from the mixture. A steamtight casing 7 is arranged to be raised and lowered on a central steam pipe 10 by tackle 8, and is secured to a turntable 2 by pivoted bolts 20 fitting in slots in the edge of the turntable. The casing can be lowered over a slaking and mixing cylinder 32, or over a wheeled frame or cage fitted with sliding shelves for supporting bricks during the hardening process, and is fitted with a safety-valve, pressure gauge, guide sleeve 17, perforated steam coil 27, and pipes or couplings with cocks for connecting it with the steam supply pipe and a cooling or annealing chamber 29. The mixing-cylinder is mounted on wheels 33 adapted to run between the retaining bars 15 of the turntable, and is fitted with mixing-blades 27, and formed with projections 39 by which it can be raised and tilted. The turntable is rotated by means of a shaft and a pinion gearing with a crownwheel, while a central shaft 34 of the mixer is fastened to a fixed shaft 36 and is provided with stationary blades 35. Instead of using a movable casing, the turntable or platform 2 may be raised with the mixer or cage up to a fixed overhead casing by a vertical hydraulic ram, or screw and bevel nut arrangement. In another form, two or more mixing-drums are carried by radial arms of a rotary shaft so as to balance one another, and are provided with manholes and square axles which are secured in square recesses in the ends of the arms by removable caps and bolts. An axle at one end of each drum is made hollow and fitted with a cock for the admission and escape of steam or water. In another arrangement, a horizontal rotary drum is made with a shell sloping to the manholes through which the slaked mixed material is discharged into hoppers fitted with sliding bottoms operated by a lever. Below the hoppers are coarse and fine meshed sieves suspended by links and rocked by a crank disc and slotted bar or the like. Fig. 9 shows a vertical mixing and slaking chamber 70 with inlet and outlet manholes 76, 77, an agitator 71 rotated by a vertical shaft and bevel gearing, steam pipes 85 for connecting the chamber in series, and a steam jacket 83.

Patent GB-190304533-A (GB)
Title: A New or Improved Method of Regulating the Voltage of Alternating and Continuous Current Generators by Means of Alternate Current Excitation.
Filed: 1903-02-26
Granted: 1904-02-26
Abstract: 4533. Crompton & Co., and Goldschmidt, R. Feb. 26. Dynamos, regulating.-Relates to a method of regulating a direct-current dynamo by the use of an alternating current in a compounding field coil, and to the application of such a dynamo as the exciter of a self regulating alternating-current generator or alternator in which the voltage rises as the current drawn off increases. If the dynamo is worked at about the "knee" of its characteristic as regards the shunt or ordinary field coil, and if the exciting power of the alternating current in the compounding-coil S2 is less than that of the current in the shunt coils S1, the dynamo voltage is pulsating and unidirectional, and varies, in its mean value, inversely as the compounding-current. The pulsating voltage is rendered practically continuous by the use of a choking-coil D in series with the dynamo, and is regulated by varying the compounding-current. In the application of a dynamo B, regulated in this manner, as the exciter of an alternator A, the alternating current for the compouuding-coil S2 is the resultant of two opposing voltages, drawn from a resistance R in series with the alternator A and a transformer T placed across the alternator terminals. The "resistance voltage" is normally less than that of the transformer T, but increases with the alternator current until this current is a maximum, when the voltages neutralize each other. The current in the coil S2 thus varies inversely as the alternator current, so that the dynamo current which excites the alternator increases with the alternator current. The opposing voltages may otherwise be taken one from a series transformer, replacing the resistance, and the other directly from the alternator terminals. The same result is obtained by the use of two compounding-coils S2 in parallel and in series respectively with the alternator. The compounding-coil may be wound on the same part of the dynamo field magnets as the shunt coil, or on the yoke part. In the case of multiphase alternators, multipolar exciters are employed, the compounding-coils carrying the different phases of the alternating current being wound between the several pairs of poles. Small alternators may themselves be wound with the compounding-coils, but with this arrangement a superposed voltage of double frequency is obtained. When several alternators are excited by the one dynamo, the regulation is obtained by the use of auxiliary compounded dynamos in series with the main exciting-circuit and each arranged to regulate the corresponding alternator. Instead of compounding the dynamo as described above, it may be driven by a continuous-current motor having a compounding coil fed by the alternator current; an increase in the alternator current then increases the motor speed, and correspondingly increases the dynamo voltage.
