Title: Improvements in Valves for Air Brakes.
Inventor: GUNCKEL WINFIELD ORLANDO
Filed: 1898-02-21
Granted: 1898-03-26
Abstract: 4295. Gunckel, W. O. Feb. 21. Brakes.-Valves for air brakes. E is the trainpipe, A the auxiliary reservoir, a<1> the pipe to the brake cylinder, and B the casing of the triple valve. The casing B contains the cylinder C, with piston I and springs h, g, and contains the chambers b, c, d, the passages to which are controlled by the slide valve J and intermediate slide valve K. Air enters by the train-pipe E, lifts the valve E', and passes by the port 5 and check valve 8 to the chamber b, and thence to the auxiliary reservoir A. It also passes by the channel e' to the cylinder C. During this operation the chamber d from the brake cylinder is connected to the exhaust passage 4, which is always in communication with the atmosphere. For a service stop, a slight drop in pressure in the train-pipe E causes the piston I to move a short distance to the left, whereupon the chamber d is cut off from exhaust and the small passage 6 is opened for a gradual application of the brake. For a quicker service stop, a larger drop in the pressure in the train-pipe causes the piston I to move to the left so far that the slide valve J carries the second valve K with it, so as to open the larger passage 2. For an emergency stop, the still larger drop in the pressure in the train-pipe causes the passage 2 to be uncovered and the chamber d to be also connected by the valve cavity 12 with the chamber c, so that air also enters the chamber d from the train-pipe. In a modification, the valves E<1> and 8 are dispensed with.

Abstract: 11,424. Marino, P. June 1. Secondary b a tteries.-Each positive electrode, Fig. 2, is a thin sheet of lead, flat or corrugated and, preferably, perforated w i t h numerous holes. It is covered with a layer of minium or a mixture of minium and graphite rendered fluid and adherent by a liquid consisting of water, guncotton, and caustic soda or potash, to which benzene may be added to remove grease from the metal. The negative electrode consists of a similar plate of lead, aluminium, or other metal covered like the positive electrode, but with litharge instead of minium. The plates are arranged in a horizontal manner with porous rigid partitions of asbestos, unglazed porcelain, magnesia paste, &c. between them, and the plates thus arranged are tied together in bundles. The plates are formed by first treating them with an electric current while they are immersed in a double sulphate of lead and ammonia, which is obtained by precipitating lead acetate by sulphuric acid, and saturating the excess of acid with ammonia. The plates are finally formed in a solution made by adding sugar and water to the glycerate of calcium, barium, or strontium. The electrolyte used in the battery consists of an aqueous solution of phosphoric or other oxy-acid of phosphorus, to which a few drops of hypophosphorous acid are added.

Abstract: 15,977. Higgins, W., and Sandilands, H. Aug. 4. Acetylene.- The generator and gas holder are combined. Within the lower part of the holder tank b, and immersed in the water thereof, are placed one or more retorts or closed horizontal casings c', into each one of which is placed a removable carbide holder h, divided by partitions of gradually increasing height into compartments h<1>, h<2>, h<3>, h<4>. The front of the retort is securely closed by a door d. The bell is provided with an air escape cock, and with a bracket r' carrying a tube r, which slides over a fixed tube s and to which is pivoted a spring tappet q. As the bell falls, in consequence of the consumption of gas, the tappet depresses the end of a lever p, whereby a cock n on the water supply pipe m, leading from the tank b or from a separate water supply, is turned to deliver water to the carbide in the first compartment h<1>. As the bell rises, the cock is turned off by a weight w. When the carbide in one compartment is all decomposed, the water overflows into the next, and so on. When all the compartments have been flooded, the tappet q falls lower and similarly operates a water cock n' on a pipe m<1> leading to the second carbide holder. The liberated gas passes by a pipe, having a non- return valve k<1> at its upper end, to the bell, and thence through a tube u to a cooling-chamber t arranged beneath the water tank, from which it passes to the service pipe. The Provisional Specification describes the carbide receptacles as perforated vessels over which the water is discharged by a sprinkler. In addition, a number of perforated carbide holders may be attached to the bell at varying heights so as to be dipped into the water and to be withdrawn again as the bell falls and rises respectively.
