Patent GB-189921816-A (GB)
Title: Improvements in Hydraulic Brakes for Railway and Tramway Vehicles.
Inventor: DUREY CAMILLE
Filed: 1899-10-31
Granted: 1900-01-27
Abstract: 21,816. Durey, C. Oct. 31. Brakes.-Relates to hydraulic brakes, in which each vehicle is provided with a pump, driven by an eccentric or other means from one of the axles, and supplying water, under electrical or other control, to the brake cylinder. In the diagram, Fig. 1, the pump c is driven by an eccentric on the axle d. The suction side is connected to a tank b, and the delivery side to the brake cylinder a, which is also connected to the tank by a pipe s. 90 is a hand-valve, and t an electric switch, by which the brake can be controlled. Fig. 2 shows a longitudinal section of the pump, which is doubleacting, the displacement of the lower end being twice that of the upper end, so that the same quantity of water is delivered at each stroke. So long as the solenoid 30 is energized, the suction valve is held open, and no water is supplied to the brake cylinder. Should the circuit be broken, automatically by the parting of the train, or by the switch t, Fig. 1, the suction valve is set free, so that water is supplied by the pipe i to the brake cylinder, and the brakes thereby applied. A spring safety-valve 28 allows water to pass from the delivery to the suction side of the pump. Fig. 4 shows a longitudinal section of the brake cylinder, and Fig. 6 a cross-section through the valve chamber connected therewith. The brake plunger is made in two sections 34 and 38, held apart by a helical spring. In the part 34 is secured a tube 40 closed at its outer end and surrounding an open tube 41 attached to the back end of the cylinder. The water supplied by the pipe i passes by the valve 46 to the interior of the tube 40, and forces out the plunger to move the brake blocks up to the wheels. On a slight rise of pressure due to the application of the brakes, the spring valve 71 is raised to admit water behind the part 34 and apply the brakes with great force. While applying the brakes, the circuit through the electromagnet 57, Fig. 6, is broken by the switch t, Fig. 1. The valve 61 is then forced on to its seat by a spring to close the passage 56. To take off the brakes, the circuit is made through the magnet, and the valve 61 lifted. Water from the brake cylinder can then pass by the passages 56 and 53 to the pipe s, which conveys it back to the tank b. The brake can be taken off by hand, by means of a cock 64 which connects the cylinder with the passage 53. When the brake plunger is being moved by the water in the tube 40, water is drawn from the tank, past the valve 48, to fill the space behind the part 34 of the plunger. Fig. 8 shows a longitudinal section of the hand-valve 90, Fig. 1, by which the water delivered by the pump is directed into the brake cylinder or back to the reservoir. By holding both valves off their seats, the brakes are taken off.

Title: Improvements in Evaporators.
Inventor: SIMPSON FRED
Filed: 1900-02-16
Granted: 1901-01-12
Abstract: 3080. Simpson, F., and Woods, A. R. T. Feb. 16. Feedwater, purifying.-Relates more particularly to evaporators for producing fresh water from seawater for boiler feed. The invention consists in arranging the apparatus so that the steam produced in the evaporator is raised in temperature and utilized as a source of heat to aid in evaporating the liquid in the evaporator. Fig. 1 shows one method of carrying the invention into effect. The steam given off in the evaporator 1 is passed through the pipe 6, and meets live steam, which is admitted through the pipe 4 and injector 5, so that the steam given off in the evaporator is raised in temperature and pressure and enters the coil 2 through the pipe 3. The uncondensed steam is passed into a coil in the vessel 7 to heat the water on its way to the evaporator 1. In another method, the steam from the evaporator is first passed into a vessel where it is heated by a coil through which live steam is passed, and is then compressed in a pump operated by the live steam, and the primary and secondary steams then flow through one pipe into the coil in the evaporator. When the water is required for potable purposes, the live steam is preferably obtained by evaporating a portion of the fresh water obtained from the evaporator 1.
