(4.) In apparatus for the generation of gas, the combination with one or more retorts suitably mounted within a furnace, of an enricher consisting of a box or receptacle surrounded with a water-jacket and having a cistern for the volatile enriching-oils provided with a branch-pipe having a burner arranged beneath the same for maintaining a uniform temperature, substantially as described. (5.) In apparatus for the generation of gas, the combination with one or more retorts suitably mounted within a furnace and discharging into a series of horizontal pipes arranged within the flue of the said furnace, of a condenser, a washer, scrubbers, a gasometer, and an enricher, all arranged substantially as described, and shown in the drawings, comprising a plant, suitable branch-pipes and cocks being provided for the direction of the gas either direct from the scrubbers or through the enricher as may be required, substantially as described.

No. 17279.—19th November, 1903.—MURRAY CONNINGTON, of 40, Wall Street, City, County, and State of New York, United States of America, Attorney. Improvements in fluid-pressure brake mechanism.

Claims.—(1.) In a fluid-pressure brake system, the combination with a train-pipe normally charged with pressure, of apparatus on an engine and apparatus on a car capable of operation by a reduction of train-pipe pressure to apply brakes, and means under control of the engineer for alternately holding brakes applied on the engine while releasing brakes on the car, and vice versâ. (2.) In a fluid-pressure brake system, the combination of mechanism on a car and mechanism on an engine automatically operative to apply brakes on a reduction of pressure in a train-pipe, and mechanism under control of the engineer for, at one time, alternately releasing brakes on the engine while holding brakes applied on the car, and vice versâ, and, at another time, applying and releasing brakes conjointly on the engine and car. (3.) The combination with a brake-cylinder, an auxiliary reservoir, and a triple valve, on a car, of a brake-cylinder, an auxiliary reservoir, and a valve-device automatically operative to apply brakes, on an engine, and a valve mechanism capable of operation by the engineer for controlling said apparatus on car and engine, and for applying and releasing brakes, at one time alternately and at another time conjointly between engine and car. (4.) In a fluid-pressure brake system, the combination with a triple valve and a brake-cylinder on a car, a valve-device automatically operative to apply brakes and a brake-cylinder on an engine, of means under control of the engineer for alternately releasing the brakes on the engine while the brakes on the car are set, and for holding brakes applied on the engine while releasing on the car. (5.) In a fluid-pressure brake system, the combination with a triple valve and a brake-cylinder on a car, a valve-device automatically operative to apply brakes and a brake-cylinder on an engine, of means capable of control by the engineer for operating said triple and automatic valve-device to application and release or normal positions, and similarly controlled means, independent of the movement of the engine-valve device, for alternately releasing and applying brakes on the engine while the triple on the car is respectively in positions for applying and for releasing brakes. (6.) In a fluid-pressure brake system, the combination with a triple valve on a car and a triple valve on an engine, of means capable of operation by the engineer for moving both triples to application position, and a similarly controlled supplemental valve for releasing brakes on the engine, independently of the movement of either triple, through a passage leading from the cylinder to said valve. (7.) In a fluid-pressure brake system, the combination of an automatic valve-device operative by a reduction of pressure in a brake-pipe to admit pressure into a brake-cylinder, an unobstructed passage leading to said cylinder, which is independent of said automatic valve-

device, and means operated by the engineer for admitting pressure to the cylinder through said passage and for controlling said pressure after its admission independently of the position of said automatic valve-device. (8.) In a fluid-pressure brake system, the combination with a brake-cylinder and a valve-device automatically operative to apply brakes, of a valve-seat, a free and unobstructed passage leading from said valve-seat to said cylinder, and a valve capable of operation by the engineer and independent of the brake-valve proper for controlling the flow of pressure through said passage and at the same time controlling all exits from said cylinder, whereby any desired pressure may at any time be admitted to said cylinder and maintained or increased or decreased at will. (9.) The combination with a valve-device controlling the admission of pressure from an auxiliary reservoir to a brake-cylinder, of means capable of control by the engineer, and including a passage independent of the movement of said valve-device, for admitting pressure to and exhausting it from the cylinder, and an unobstructed passage from said valve-device to the cylinder which may always be opened instantly said valve-device moves to application position. (10.) The combination with a valve-device controlling an admission-passage to and an exhaust-passage from a brake-cylinder, a valve, independent of the brake-valve proper, capable of operation by the engineer for closing said exhaust-passage, a passage controlled by said valve for admitting pressure to said cylinder, and an unobstructed passage from said valve-device to said cylinder, which may always be opened instantly said valve-device moves to application position. (11.) The combination with a valve-device and a brake-cylinder, of a valve-seat, means of communication from the valve-seat to the exhaust-passage of said valve-device and to the brake-cylinder, and a valve, independent of the brake-valve proper, operating on said seat for controlling such communication so that its movement may cause admission of pressure to said cylinder and at the same time close said exhaust-passage. (12.) The combination with a valve-device for applying and releasing brakes and a brake-cylinder, of a valve-seat through which one current of pressure flows to the brake-cylinder and another from the exhaust-passage of said valve-device, and a valve, independent of the brake-valve proper, working on said seat, capable of operation by the engineer, for alternately opening one current and closing the other, and vice versâ. (13.) The combination with a valve-device, and a brake-cylinder, of a valve-seat through which one current of pressure flows to the brake-cylinder and another from the exhaust-passage of said valve-device, and a valve, independent of the brake-valve proper, working on said seat, capable of operation by the engineer to either of three positions: First, for opening the first of said currents while closing the second; second, for opening the second while closing the first; and, third, for closing both of said currents. (14.) The combination with a valve-device controlling an admission and an exhaust passage to and from a brake-cylinder, a valve-seat and a valve operating thereon and controlling said exhaust-passage leading to said valve-seat, whereby the engineer may govern the release of the brakes independently of the position of the said valve-device and cause the recharging of the auxiliary reservoir either before or after release.

(2.) In the protecting of openings, a screen composed of main or upright bars in pairs, but brought into one at the top end for compactness, strength, and lightness, kept close or evenly apart by being fastened or pivoted to the centre of crossings of a number of crossed bars, and sliding or rolling on bars that fold to secure the whole when shut, all substantially as set forth. (3.) Screens composed of upright bars in pairs brought together to form one at the upper ends, kept in place, either shut, open, or partly so, by crossed struts or bars, sliding to outer uprights and secured at centre crossings to said intermediate and end uprights, all substantially as set forth, and as shown on the drawing.
