Patent GB-189923407-A (GB)
Title: Improvements in Flush Valves.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1899-11-23
Granted: 1900-02-03
Abstract: 23,407. Thompson, W. P., [Marsh, E. A.]. Nov. 23. Water-waste preventers.-Regulator valves in service pipe. The casing, which is attached to the supply at A' and has an outlet A', has at the top a cylinder in which slide two pistons C, D. The outlet chamber is narrowed at r by the shape of its walls and by a cylinder D<3> depending from the piston D, and it is normally closed by the valve d on the piston D, while a hole d<3> in the piston D is normally closed by the valve h on the piston C. A second hole b in the piston D is controlled by a flap valve, the guard b<4> of which is so shaped that the further the valve opens the greater is its resistance to opening. In operation, the piston C is lifted to the position shown by the lever G<1> and rod H<1>, which are then allowed to drop. The time of descent of the piston C from this position, and therefore the volume of water passed, are determined by the size of the adjustable opening between the valve a<1> and the tube a. The hole d<3> being opened, water flows from the chamber B<5>, the pressure in which is therefore reduced so that the piston D can be raised to open the valve d by the supply pressure acting on the outer part of its lower side. The stem c of the piston D passing through the hole d<3> is bigger at the top than the bottom, and thus, as the piston C descends, the outlet d<3> is contracted, the pressure in the chamber B<5> increased, and the valve d gradually closed. Any increase of pressure in the upper part of the outlet chamber tending to lift the piston causes a corresponding increase in the pressure in the chamber B<5>, but any increase of the pressure in the upper part of the outlet chamber over that in the lower part diminishes the lifting force on the extension D<3> of the piston D.

Granted: 1900-05-26
Abstract: 4935. Solomiac, E. March 15. Water-tube boilers; water-circulation, promoting. - Fig. 1 shows diagrammatically the construction of a boiler. The steam and water drum A is connected to the water-distributing d r u m B by tubes a and b, the former of which are exposed to the furnace gases, and cause a vigorous circulation between A and B. The larger steam and water drum C is connected to A by a coiled tube S, also exposed to the furnace gases, and communicates through a valve u with an intermediate drum D, which also communicates with the drum A through a valve t. The pressure in A is greater than that in C, so that water is forced from the former into the latter through the tube S, and is returned through the drum D by suitably manipulating the valves t and u, which in practice is done automatically. Figs. 2 and 3 show longitudinal and cross sections respectively of a boiler in which there are se eral drums A and D on each side. The tubes a form the side walls of the furnace, and also form return flues in which the tubes S are placed. From these side flues the hot gases pass along flues 2 and 3 containing tubular feedwater-heaters. d are the valves controlling the communication between the drums C and D and D and A respectively, the valves being operated by steam cylinders.

Abstract: 18,502. Froment, R. Feb. 16, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Arc lamps.-An upper carbon o is controlled by the regulating-apparatus shown, which is movable between two tubes a forming part of the frame of a lamp. A series solenoid t is wound on a copper tube between iron plates q, r, and is surrounded by iron half-cylinders 1 ; the plates q, r have V-slots to fit and slide on the tubes a, but are normally held stationary thereon by two hooked gripping- levers 12, the inner ends of which are pressed up by a conical block 7 and a spring 6 in the hollow movable core 2 of the solenoid. The upper iron plate q carries a short iron core. Downward movement of the movable core 2 is limited by a central rod and a nut 11. The movable core carries an insulated holder y for the upper carbon, which is connected by flexible conductors z, v, through the solenoid t and a resistance, to one terminal of the lamp. The gripping-levers 12 have cross-pins 13 resting loosely on the upper iron plate q. In operation, when current passes, the solenoid raises the core 2 and upper carbon, striking the arc, and causing the levers 12 to fix the regulating-apparatus on the side tubes ; the core 2 afterwards gradually descends in the solenoid until the levers are released sufficiently to allow slipping on the side tubes. The tubes a are secured at their upper ends to a frame provided with a suspender and with insulating-bobbins carrying a wire resistance. At the lower ends the side tubes are connected by a yoke, on which are vertical pins to receive a loose plate ; the neck of an arc-enclosing cylinder is pressed down on an asbestos washer upon this plate by a lower carbon-holder, which is held down inside the cylinder by a screw and a nut below the plate. The cylinder carries a loose cover. When the regulating-apparatus has been raised, the loose plate, with the lower carbon-holder and the glass cylinder, can be lifted from the yoke and removed.
