Title: Improvements in Air Suction or Vacuum Brake Apparatus for Trains of Vehicles.
Inventor: LENZ AUGUST
Filed: 1903-04-01
Granted: 1903-07-09
Abstract: 7616. Lenz, A. April 1. Brakes.-Relates to means for making a vacuum brake for railway trains act nearly simultaneously throughout the length of the train. The trainpipe 1, Fig. 1, is connected to the lower end of the brake cylinder 10 by a pipe 8, in which is placed a lift-valve 9 formed with a small hole in it, so that the air admitted to the train-pipe, when putting on the brakes, is throttled in its passage into the brake cylinder, but air leaving the brake cylinder, when releasing the brakes, passes freely into the train-pipe. The brakes at the rear end of the train thus come into operation before those at the front end exert their full force. For quick application of the brakes in case of danger or otherwise, a quick-action valve 2 on each vehicle is arranged to admit air to the train-pipe on each vehicle in succession, when sufficient air is admitted to the train-pipe through the brake-operating valve. In the valve 2, a cup valve 3 is connected to a diaphragm 5, the space on the upper aide of which is connected by a pipe 7 to an auxiliary chamber 6. A lift-valve 17 carried by the valve 3 is arranged to open downwards. In exhausting the air from the train-pipe, a vacuum is produced in the chamber 6. On admitting air freely to the train-pipe, the valve 17 is closed and the valve 3 is lifted ; communication is thus established with the atmosphere through a flap-valve 19. The inrush of air causes a rapid action of the quick-action valve on the next vehicle and so on, thus causing a rapid increase of pressure in the train-pipe from end to end. The cover of the valve 2 is arranged to hold the valve 17 open, after the valve 3 has been lifted. Air is thus admitted to the chamber 6 through a throttled passage between the valve 3 and the cover. This throttling prevents premature closing of the valve 3. On again exhausting the trainpipe, the valve 3 is closed, the valve 17 remaining open. Vehicles which are used as last vehicles of trains are fitted with a modified form of the valve 9 and with an additional valve 15, Fig. 2, in the socket 14 to which the coupling - pipe 16 is fastened when not in use. This arrangement has the effect of causing the brakes to be applied quickly when the vehicle is the last vehicle of a train. A diaphragm 11 above the valve 9 is connected to it by a bolt 12 passing loosely through the valve, and the space above the diaphragm is connected by a pipe 13 with the valve 15. When the pipe 16 is coupled to the socket 14, the valve 15 allows a vacuum to be formed in the pipe 13 when the air is exhausted from the train-pipe. When air is admitted to the train-pipe to apply the brakes, the valve 15 closes, and the diaphragm 11 lifts the valve 9 and allows a free passage of air from the train-pipe into the brake cylinder. If the pipe 16 is coupled to another vehicle, the valve 15 is inoperative, and the valve 9 acts as in the arrangement shown in Fig. 1.

Title: Manufacture of Mordant-dyeing Monoazo-dyestuffs.
Filed: 1903-04-11
Granted: 1904-02-11
Abstract: 8406. Abel, C. D., [Akt.-Ges. f³r Anilin Fabrikation]. April 11. Dyes, artificial-Mordant-dyeing monoazo dyestuffs having the general formula are produced either by combining diazotized p-nitro-o-amidophenol, or one of its homologues, or one of the nitro, chlor, carboxylic, or sulphonic acid derivatives thereof, with an azo dye-stuff component or a sulphonic acid derivative thereof, and then reducing the resulting dye-stuff by agents such as sodium sulphide, or by combining diazotized p-acetamido-o-amidophenol, or p acetylalkylamido-o-amidophenol, or one of their homologues or nitro &c. derivatives, with the dye-stuff component or derivative thereof, and afterwards eliminating the acetyl group. The dyes obtained yield in acid baths tints varying from red to violet and blue or brown, which are fast against soaping, milling, and especially potting. With oxidizing-agents, such as chromates, the shades are darkened. The dye prepared from p-nitro-o-amidophenol and #-naphthol sulphonic acid (Shaffer's salt), when reduced, dyes wool violet-red shades, which with chromates turn black. The dye obtained from acetyl-p-amido-o-nitrophenol by reducing, diazotizing, combining in an alkaline solution with sodium 1-naphthol-5-sulphonate, and saponifying, dyes wool bordeaux-red shades, which are turned to an intense black by chromates. The dye prepared from acetyl-p-amido-o-amidophenol-osulphonic acid and #-naphthol gives violet-red shades, which are turned black by chromates. A similar dye, in which chlorine replaces the sulphonic acid group, gives a blueish-bordeaux shade, which is also turned black. The dye obtained from sodium p-acetyl-methylamido-o-amidophenol-osulphonic acid, produced by nitrating acetyl-pmethylamidophenol-o-sulphonic acid, and reducing, and #1 - naphthol - #3 - sulphonate dyes wool a bordeaux-red shade yielding with chromates a fast blue-black.

Abstract: 12,264. Blivet, F. May 29. Floors; sound deadening in buildings; parquetry; ceilings.-A sound-proof floor is made by laying a mat so as to leave clear spaces above and below between it and the ceiling and the floor. As shown in Fig. 1, the mat I is laid on bearers L which hook on to the main girders F carrying the blocks or plates H forming the ceiling. Battens T rest on the mat and support the parquetry. A false or intermediate ceiling P, carried by cement or plaster keys P', provides space for wires, heating-pipes, &c., D. The mat I may be fireproof or damp-proof, and may be built up of several layers such as cloth, felt, or wire gauze, between paper or asbestos, as shown in Fig. 2. A number of forms of battens and of parquetry joints are described. The battens generally are mortised and may be made in one or more parts of wood or metal, and are adjustably fixed by screws and slotted holes. Examples are shown in Figs. 5 to 12, which also illustrate various forms of the parquetry blocks and their connections. These include various forms of tongues, grooves, and rabbets at the sides and ends, including loose tongues N projecting at the side and ends, as shown in Fig. 12. When the opposite ends of a block are tongued and rabbeted and the blocks laid alternately, the strip G, Figs. 7 and 7<b>, serves to hold them on a level. To adjust the height of battens, double wedges are used, as shown in Figs. 14 and 15, and the wedges have plates attached to hook over the girders. Forked keys, Figs. 16 and 16<a>, are used to hold plaster &c. applied to ceiling strips. The Y-shaped piece shown in Fig. 17 may be used for securing overlapping ends of bearers on joists by turning down and nailing the ends.

Granted: 1903-10-22
Abstract: 20,323. Hodges, C. B., and Hodges, F. W. Sept. 21. Lubricators for locomotives &c. of the condensation displacement sight-feed type, have an oil reservoir 4 with axis horizontal, and such that the number of oil feed tubes may be increased by increasing one only of the horizontal dimensions of the reservoir, the sight-feeds being arranged in rows and all visible from the front or side. Steam from the boiler enters by the pipe 1 and is condensed in the chamber 5. The water enters the reservoir 4 through the passage 6, and the displaced oil passes by the tube 7 from the top of the reservoir to the chamber 8, whence it passes through the nozzles 9, 9<a>, 10 and oil feed pipes 16, 16<a>, 17, past the observation glasses 13, by the pipes 2, 3 to the cylinders. Within the reservoir are tubular chambers 11, 11<a>, 12 which, with the intersecting oil pipes 16, 16<a>, 17, serve to brace and strengthen the reservoir. Each of the nozzles 9, 9<a>, 10 is placed between two thick glasses 13, of the bull'seye type, with their axes in line, mounted either directly or in removable screw-threaded cells 14 in the chambers 11, 11<a>, 12, by means of which the ascending drops of oil can be viewed. The glass 13 shown in Fig. 11 is rectangular or square in section, with parallel ends, or may be of circular section, or octagonal, as shown in Fig. 14, and rests against the shoulder 18 which is lined with packing. It is retained by the cap 15 screwed to the cell 14, and packing 22. The range of vision through the glass is widened by total reflection at the inclined sides, as shown by the dotted lines, Fig. 7. Any form of glass to produce this effect may be used. If only one glass be used it may be provided with an opaque or polished reflecting-surface 20, Fig. 4, in the rear. The invention is also applicable to the :type of lubricator in which drops of water pass through the oil, and as a means for facilitating observation of the height, position, or movement of a liquid in a lubricator.
