Patent GB-190108927-A (GB)
Title: Improvements relating to Hydraulic and other Fluid Controlling Valves.
Filed: 1901-04-30
Granted: 1902-03-20
Abstract: 8927. Marks, E. C. R., [Brindley, H. S. B.]. April 30. Lift valves.-A valve without packing specially adapted for use with hydraulic machines is shown in Figs. 1 and 2. An eccentric spindle e actuated by a handle h acts on a stud d on the inlet valve a and abuts against a shoulder on the exhaust valve j. The inlet valve is ribbed so that fluid from the inlet c passes to the top of the valve and with or without the assistance of a spring f presses it on to its seat. The exhaust valve is similarly closed. By moving the handle in one direction or the other, either valve can be opened to admit fluid to the machine pipe m, or from the machine pipe to the exhaust pipe l. The valves may be arranged at varying angles to one another. A modification for use with high pressures, or for large valves, has a pilot valve n, Fig. 5, inside the inlet valve a, and when it is raised, it strikes the cap o and lifts the inlet valve. The exhaust valve has a similar pilot valve p fitted with a cap which slides over the end of the exhaust valve.

Title: Improvements in or relating to Controlling Apparatus for Electric Motors.
Inventor: BOULT ALFRED JULIUS
Filed: 1901-08-19
Granted: 1902-08-14
Abstract: 16,615. Boult, A. J., [Christensen, N. A.]. Aug. 19. Brakes.-Relates to automatic devices for simultaneously starting and stopping the several motors of a multiple-unit system employed in the operation of air-compressors or vacuum pumps, by means of which devices the motors are started and stopped in accordance with the variations of fluid pressure in the reservoirs. The invention is particularly intended for air-brake service on electric railways. Fig. 1 is a diagram showing the equipment for two cars. A and B are the main conductors, and E an equalizing-conductor running the length of the train. The motors C actuating air-compressors or vacuum pipes are all connected in parallel, and are started and stopped by means of electromagnetic switches D, the magnet coils of which are connected between the main A and the equalizing-conductor E. Connection between the equalizing-conductor and the return main B is automatically made and broken by one of the controlling-switches F, each of which is actuated by a pair of electromagnets 7, 8, the circuits of which are controlled by a switch 11 constructed so as to respond to variations of fluid pressure. When the pressure in the reservoir rises or falls beyond a certain limit, the movable arm of the switch 11 closes the circuit through one or other of the magnet coils 7, 8 and operates the core 19. Motion of this core to the left opens the switch F while motion to the right closes the same. In the former case, connection is at the same time established between the switch 11 and the return conductor B by the closing of an auxiliary switch 12,13.

Title: Improvements in the Process of Manufacturing Building Blocks or Bricks and Apparatus for use therewith.
Inventor: BARRETO BARON VICTOR
Filed: 1901-08-21
Granted: 1901-11-23
Abstract: 16,794. Barreto, Baron V. Aug. 21. Bricks; building-blocks.-Relates to apparatus for manufacturing and hardening bricks containing lime. About 2 parts of ground ashes, clinkers, or sand, and 1 part of unslaked lime, are placed in a drum mounted on rails, sufficient water is added to slake the time, and the drum is closed and rolled backwards and forwards on the rails. A steam pressure of about 40 lb. per sq. in. is generated by the slaking of the lime. The drum is fitted with steam-tight covers, a perforated water supply pipe, a safety-valve, an air vent cock, a pressuregauge, and an operating-cable. A further supply of ashes or sand is added to the slaked mixture from the drum to produce a mixture containing about 10 per cent. of lime. This mixture is moulded into bricks or blocks, which are slacked on the perforated platform y of a truck, which is run on to the rails t in a steaming-cylinder o. The bricks are hardened by subjecting them to the action of steam at a pressure of 110 lb. per sq. in. for about 12 hours. The end of the cylinder is secured in place by pivoted bolts q, which fit in recesses r, and are provided with nuts. Steam is supplied to the cylinder through perforated pipes u, and is drawn off through a valve w when the bricks are hardened, and may be passed into a second cylinder containing another load of bricks. Superheated steam may be used, and the top row of bricks may be protected from condensed vapour by a shield or baffle-plate.

Granted: 1902-05-01
Abstract: 5339. Naylor, W. March 4. Chairs.-Relates to outdoor chairs with turnover seats and fixed or reversible backs. The seat a is pivoted at its centre of gravity on pivots b to uprights c made of tubular metal. The back is in two parts e, e<1> connected by barsf. The parts e, e' slide in slots in arms d pivoted at d', and are pressed downwards by a spring h. Fig. 3 shows the position of the seat when occupied ; the weight of the occupant raises the back and compresses the spring h. When the chair is vacated, the parts e, e<1> of the back descend and reverse the seat, which then occupies the position shown in Fig. 1. On reversing the back, the guides j act on pins g and lift the part e over the centre of the seat. The guides j<1> may be dispensed with ; in this case the parts e, e<1> must be raised by hand when the back is reversed. A cross-piece l acts as a dress-guard, and facilitates reversal of the seat.

Patent GB-190219060-A (GB)
Title: Improvements in and connected with Centrifugal Machines.
Inventor: MACFARLANE JAMES WRIGHT
Filed: 1902-08-30
Granted: 1903-08-27
Abstract: 19,060. Macfarlane, J. W. Aug. 30. Supporting or mounting; lubricating.-In centrifugal machines of the " Weston" type, the connection between the revolving part of the motor and the revolving spindle is constructed in such a way as to prevent oscillation of the motor due to oscillation of the spindle. In Fig. 1, where an electric motor set below the centre of suspension A of the machine is shown, the motor is mounted on a hollow sleeve B through which the spindle C passes. The sleeve rotates in bearings L, L<1>, which form part of the fixed casing M. Consequently the armature E does not oscillate with the spindle C, which is supported in the usual manner upon rubber buffers D. The weight of the armature is carried by the flange F which rests upon, and drives, the friction blocks G, the blocks being attached to the outer spindle K of the machine. In a modification, the bearing L is in the form of a stationary sleeve fixed rigidly to the casing, while the armature rotates on the sleeve. The motion is transmitted by weights which are thrown centrifugally against the inner surface of the pulley H. Springs attached to the weights permit oscillation of the spindle without disturbance of the motor. The driving may be confined to the friction due to the bottom faces of the weights, which may be cast together in the form of a ring. In Fig. 3 the motor is shown supported mainly above the centre of oscillation A, while the field magnets M are situated within the armature E. The hollow fixed spindle contains the revolving spindle B, which, at its bottom end, is rigidly attached to the outer spindle K. The weight of the machine is supported on the bearing L<2>. The armature E is hung from the plate H, secured to the independently-supported spindle N. The armature transmits its motion through the cap F of the spindle B. In the modification shown in Fig. 4, the armature E is within the field magnets M, and is hung from a bearing L<5> at the upper end of its spindle. The motion of the armature is transmitted from its lower end to the revolving spindle of the machine through centrifugally-acting weights G, attached to the armature spindle by springs. Instead of the weights, the springs alone may be used as when the machine is driven by a fluid motor. The fluid motor may be secured directly to the machine-spindle and thus oscillate with it, the bearings in this case being at the bottom end of the enclosing fixed spindle. In connection with outer and inner revolving spindles, as in Figs. 3 and 4, the driving may be effected by a belt working upon the pulley attached to the outer spindle. In Fig. 7 an automatic oiling-device W is shown. Oil from the chamber W<1> on being forced through the central vertical passage is thrown out, and allowed to descend the dome to the bearings.
