Title: Improved Acetylene Gas Generator.
Inventor: BARTMANN LUDWIG
Filed: 1899-07-27
Granted: 1899-09-23
Abstract: 15,406. Bartmann, L. July 27. Acetylene. - Apparatus for automatically making acetylene by the intermittent con - tact of carbide with water. Two concentric cylinders A, B, preferably both closed by one cover, communicate below with one another, while the inner one encloses a fixed or weighted gas bell F, inside which is a carbide holder C. The carbide receptacle has perforated sides, and a piston D forming the top, which is connected by a rod to the top end of a stretched spring E, the other end of which is hooked to a fixed part of the apparatus. A chamber H, containing acetone, is connected by a bent tube M with the interior of the vessel B. In use, water is charged into the outer vessel, and is covered with a layer of oil in the central chamber. As gas is developed, it passes away through the cooling-coil G to the outlet I, but, if not used as fast as it is generated, the pressure forces the water away from the carbide, and generation stops, the oil preventing further action. As the pressure diminishes, owing to the use of the gas, the water again rises, and generation re-commences. If the pressure becomes excessive, the water and oil are driven below the opening to the tube M, when the gas rushes into the chamber H, where it is absorbed by the acetone, thus relieving the excessive pressure.

Title: Improvements in and connected with Fluid Pressure Engines.
Inventor: OFELDT AUGUST WALDEMAR
Filed: 1899-12-11
Granted: 1900-01-20
Abstract: 24,623. Ofeldt, A. W. Dec. 11. Combined steam and vapour engines.- Relates to motors of the class in which steam or other expansible fluid, after performing work in a primary motor, is used to heat an easily-vaporizable liquid so as to generate vapour for doing work in a secondary motor. In the arrangement shown, 1 and 2 are steam cylinders working in a compound cycle, and 6 is a cylinder in which the vapour of naphtha is caused to do work. The exhaust steam from the cylinders 1, 2 is first made to pass through the jacket of the naphtha cylinder, and thence it is delivered into the chamber surrounding the coiled-tube vapour generator 10, and thereafter may be discharged into a condenser 24. The naphtha is forced into the generator from a closed tank 13 by a feed-pump 14, which in order to prevent leakage of vapour, may be enclosed in the tank. The supply of naphtha may be automatically regulated in accordance with the exhaust steam supply by a bye-pass or return valve 19. This valve is regulated by an expansible bar 26, which is arranged so as to close the bye-pass when the heat of the exhaust is sufficient to expand the bar. The exhaust naphtha vapour is passed into the condenser 24, and the liquid is then fed into the tank 13. The naphtha cylinder and valve-chest have double stuffing-boxes, each with an intermediate space connected with the condenser.

Granted: 1901-02-16
Abstract: 6487. Borries, A. von, Worsdell, T. W., and Lapage, R. H. April 6. Compound engines; starting.-Relates to the starting of compound locomotives by causing them to work temporarily as simple engines, and consists in the provision of a small exhaust valve for the high-pressure cylinder, which is closed automatically when the intercepting-valve opens. Fig. 1 shows the additional exhaust valve b, which enables steam to escape from the receiver pipe a as long as the intercepting-valve c is closed and live steam is being supplied to the low-pressure cylinder by the pipe e. When the valve c, owing to the gathering pressure in the receiver, opens, and the supply of live steam entering at e is shut off, the valve b closes, and compound working is thereby established. In a modification, the invention is embodied in a sliding intercepting and exhaust valve. It is also applicable to flap or other valves.

Natural or coal-tar dyestuffs are chosen which remain sufficiently soluble for dyeing purposes in the presence of chrome salts. The combined tanning or dyeing liquid may consist (1) of a solution of chrome alum, hyposulphite of soda, and hydrochloric acid to which a solution of logwood previously oxidized with bichromate to a blue-black logwood lake has been added. The dark blue-black colour may be turned into a pure black by a short treatment with diluted solutions of bichromate of potash. Basic chromium sulphates or chlorides &c. may be used instead of the chrome alum, hyposulphite, and acid, and indigo substitute may replace the logwood solution. (2) To a basic chromium sulphate, chloride, or sulphite solution, a small amount of an easily-soluble tanning-extract is added, together with indigo substitute, naphthol black, orange II B, naphthol yellow S, &c. A variety of brown and yellow-brown shades are obtained, on which basic colours can be afterwards superposed, the tannic acid and acid colour in the leather acting as mordants. (3) Tanning of sheepskins is commenced with a weak solution of a chromium salt, to which a vegetable tanning-solution is afterwards added. Chrome-salt solution is gradually added to the bath until the hides are nearly tanned, and a solution of phosphine and a chrome salt is then added, and the tanning and dyeing continued together until complete. This process may be varied by commencing the dyeing before adding the tanning substances. A revolving drum is preferably used in all cases.

Granted: 1902-09-25
Abstract: 21,803. Carter, J. E., and Wright, S. A. Oct. 30. Sawing; saws, sharpening; centering work.-A machine for sawing or cutting iron bars and centering the same has a hollow spindle 3, Figs. 2 and 3, with self-centering chucks 5, 6 to hold the bar 4, which is rotated in the opposite direction to the saw or cutter 9. The saw is mounted on a saddle 41, the feed of which is gradually increased, together with the speed of the bar, as the saw cuts through the work. A sharpening-worm 93, Fig. 11, is carried by the saddle and driven at a speed to suit the saw to sharpen the teeth whilst at work. The Provisional Specification states that the leading part of the worm may be in the form of a steel cutter to clear away cuttings, while the remainder is of emery or other sharpening-material. The main shaft 35 drives a cross-shaft 37 connected by worm gearing 10 to the saw spindle and by bevel gearing 43, 46 and an inclined shaft 45 to a shaft carrying one of a pair of belt cones 30, 31. The second cone 31 drives a vertical shaft 50 connected to a worm shaft 53 for driving the spindle 3, and to a cone shaft 12 for driving a back shaft 11 connected by clutches to a screw 27 for traversing the saddle and to a screw 33 for traversing the belt-shifter for the cones 30, 31. After the saddle has moved sufficiently to cut off the bar, a stop 68 operates a pin 69 to release one end of the shaft 11, allowing it to fall out of engagement and stop the traverse of the saddle and belt-shifter, which are returned separately or together by turning a hand-wheel. A shaft 76 driven from the main shaft, and driving a centering-tool 89, is then raised by a handle 86 and locked in the centering position on a quadrant plate by a handle 87, the drill being then pressed forward by a handle 90 to centre the work. The sharpening-worm may be applied to other metalworking machines in which a saw or cutter is employed.
