Granted: 1903-05-21
Abstract: 7947. Lambert, A. April 6. Rope railways.-Consists of means whereby a hauling and winding engine may be used to operate either a derrick or a cable-way. One of the two drum barrels A', .B, which gear with the engine shaft C in a usual manner, has clamped on it a concave drum A<2>. In this condition, the engine is adapted to operate a cable-way, the hoisting-rope for the load being wound on the drum B and the traversing-rope for the carriage being given a few turns around the drum A', which, owing to its relatively-large diameter, gives a sufficiently-high speed to the carriage. By removing the barrel A', the boom-operating rope of a derrick may be wound on the barrel A' and the load-hoisting rope on the barrel B. The barrel A' is preferably formed in two parts, Fig. 4, having wide semicircular flanges a<4> to engage the barrel A<1>, and clamped on the barrel A' by bolts and flanges a<2>.

Title: Improvements in Baking-ovens Heated by Hot Air.
Inventor: BEY FRANZ
Filed: 1903-10-21
Granted: 1904-10-20
Abstract: 22,704. Bey, F. Oct. 21. Heating air and water.-A baking-oven is heated by hot air which circulates in conduits arranged in the baking-chambers and has been previously heated in a chamber by the furnace gases. In the case of a stationary oven, the baking-plate b, Fig. 1, may be driven by a hot-air motor, the cylinder c of which forms the chamber in which the air for heating the oven is heated. The furnace gases pass from the left-hand grate a to chimneys y, Fig. 2, located diametrically opposite each other and at right-angles to the grate, while the gases from the other grate pass on one side direct to one of the chimneys y, but on the other side round a tongue which extends as far as the axis of the cylinder c. The air in the cylinder being thus heated, its piston ascends until the passage d is opened ; simultaneously the slide valve opens the exit from the passage d into the valvechest, and the hot air passes through the pipe e into a box f whence it traverses pipes g underneath the baking-plate b<1> and pipes h below the roof of the oven. The pipes h are arranged at right-angles to the pipes g, and the air passes by pipes i to a waterheater k and then returns by a pipe l and passage m to the cylinder c, the slide valve having opened the exit from the passage m into the valve-box. Steam from the heater k passes through a pipe p into the baking-chambers. The cock n is opened to allow air to pass through the pipe o into the pipes and cylinder, when starting the oven, but is afterwards closed. In another arrangement, boxshaped partitioned conduits are arranged below the drawplates and on the side and rear walls of the baking-chamber, through which hot air from chambers arranged above the firegrate passes.

Title: Improvements in the Coverings of Fancy and other Card Rollers
Inventor: HARDING THOMAS WALTER
Filed: 1904-01-15
Granted: 1904-09-01
Abstract: 1047. Harding, T. W. Jan. 15. Cards, wire, for covering the fancy rollers and other parts of carding-engines. The staples are set loosely in rigid foundations, such as logs of wood, as in Specification No. 17,113, A.D. 1899, but in order to prevent dropping out while the logs are being fixed to the rollers, the teeth are suitably bent, as shown at 2 in both Figures. These bends, it is stated, increase the flexibility of the staples which are also arranged to be sufficiently loose in the holes 3 to allow of con- siderable springing back. When the card teeth are to be inclined the holes may be drilled through the log at the required angle, or, according to the Provisional Specification, the teeth may be bent to the required slope after having been filled in. Similar staples may be used in leather or other foundations.

Title: Improved Means of Constructing Seamless, Hollow Articles.
Inventor: JUSTICE PHILIP MIDDLETON
Filed: 1904-04-21
Granted: 1905-04-13
Abstract: 9201. Justice. P. M., [Voelke. F. A.]. April 21. Making hollow-ware.-In making hollow seamless articles of any shape, either closed or open and braced internally or externally, metal is deposited electrolytically on a core of fusible material, the core is removed by heating, and the shell is dipped into molten metal. The manner of making is described in connection with a spherical float braced to withstand external pressure, as shown in Fig. 1. The apparatus for forming the spherical core con-. sists, as shown in Fig. 5, of a mould formed in two parts 1, 2 and mounted to rotate about a horizontal and an inclined axis, the latter rotation being produced by the bevel-wheel 20 and the fixed friction disc 19. The strengthening-plates 8, 9 and the brace 10 are placed in position in the heated mould together with a quantity of molten wax, fusible metal, or other substance. The mould is then rotated and allowed to cool, and at the same time air under pressure is admitted through the passages 23, 24 and through the aperture 26 in the brace 10. The compressed air prevents the core from contracting as it cools, and remains enclosed in the core owing to the sealing of the aperture 26, thus increasing its strength. The core and the embedded parts are then removed and coated with graphite or other material to enable a shell of copper, nickel, or other material to be electrolytically deposited. The core is then expelled by heating in an oven to a temperature sufficient to vaporize the material, or if desired to burn out the vapour. The shell is then dipped into molten metal or alloy at such a temperature that the outer and inner layers become welded together. A third metallic layer is formed by electrolysis to protect the metals from galvanic action. The float shown is formed with a neck, but a continuous surface may be obtained by using a suitable strengthening- piece and plugging the bore as shown in Fig. 4 after removal of the core. To produce a core of shape other than spherical, the mould must be rotated or tumbled in a suitable manner.

Title: Improvements in the Manufacture of Iron and Steel.
Inventor: DAELEN REINER MARIA
Filed: 1904-04-21
Granted: 1905-04-20
Abstract: 9202. Daelen, R. M. April 21. Direct processes of obtaining; open-hearth processes.-Iron oxide is reduced directly into iron and steel by means of solid carbon and carbonaceous gases. Solid carbon, such as coke dust low in sulphur, may be mixed with the oxide, together with some binding-material, and the mass moulded into briquettes. The reduction may then be effected partly or entirely by passing the briquettes through a heated tunnel, or by placing them in soaking pits, containing reducing or carbonaceous gases. When the reduction is complete, the mass is plunged into a bath of iron or steel in an openhearth furnace of the tilting type, the slag covering preventing re-oxidation. When the furnace is full, a part of the contents is tapped off, leaving a bath of metal into which more reduced briquettes may be placed. The composition of the slag may be varied by suitable additions in order to counteract the gangue present with the reduced iron sponge. Molten pig iron may also be added to the furnace, and a second furnace is preferably used for finishing.
