Title: Improvements in Return Steam Traps.
Inventor: LEES WALTER
Filed: 1903-03-04
Granted: 1904-01-28
Abstract: 5026. Lees, W., Lees, T. W., and Lees, A. March 4. Direct steampressure apparatus. -Relates to steam traps in which the condensed water is returned to t h e boiler by the steam pressure, and more particularly to the construction and mode of actuation of the steam admission and relief valves. A spindle c is rotatably mounted in a casing over the body of the steam trap, and is actuated by a float. Valve discs d are carried on the ends of a double arm set on the spindle ; another valve disc g is similarly mounted on a lever h. These discs control the steam-admission ports a' and the relief port e', respectively. When the condensation water in the trap is below a certain level, the float holds the steam ports a<1> closed, and the relief port, which is in connection with a check valve serving to prevent condensed water from re-entering the casing, is held open, so that the pressure is relieved by the escape of steam. When the water rises high enough, the valves are reversed, and steam from the boiler enters the trap through the opening b and the ports a<1>, and drives the condensed water back to the boiler. The movement of the valves is limited by stops.

Title: Improvements in Grab or Hoisting Buckets.
Inventor: MARKS GEORGE CROYDON
Filed: 1903-03-24
Granted: 1904-03-24
Abstract: 6797. Marks, G. C., [Brown Hoisting Machinery Co.]. March 24. Grabs.-Relates to grabs or hoisting-buckets and consists of means for giving to the jaws of the grab a scraping action when closing, which renders it specially suitable for clearing corners of holds &c., and of improvements in the sides of the grab, designed to prevent the presence of large lumps in the material handled from having a prejudicial effect on the operation of the grab. The jaws D are pivoted at their lower ends on blocks b, sliding on guides T on the sides of a housing or frame H, which flares downwardly. The upper ends of the jaws are pivoted to the axle j of a pulley-block C, guided by vertical guides g in the housing H. The operating rope 0 is reeved through the block C and a block E fixed to the housing H, and the hoisting rope R is led round a pulley G connected to the housing. The guides T slope downwardly at such an angle that the blocks b slide down them, when the block C is allowed to drop, and are so shaped, that the jaws D in closing follow the path indicated by the dotted lines. The sides of the jaws are cut away, so that when the grab is closed openings are left, the edges of which slope upwardly and outwardly from the cutting- edges of the jaws. These openings are covered by extensions S<1> of the sides of the housing H. Various modifications may be made. The guides T, for instance, may be shaped so as to cause the jaws to follow a path different from that shown, or the jaws need not be pivoted on the axle of the block C.

Title: Improvements in Apparatus for Insuring Safety in the Working of Hoists, Lifts and the like.
Inventor: BOWIE DANIEL
Filed: 1903-05-21
Granted: 1903-06-25
Abstract: 11,636. Bowie, D. May 21. Lifts. -Consists of a locking-device for preventing the engine man from prematurely starting the cage, and is described in connection with a blast furnace hoist, in which there are two oppositety-moving cages. The kips A, on which the cages rest and which are normally urged towards each other, are connected by an arm and rod F<1> with a rod F sliding in bearings f. The kips are separated to allow the movement of the cage by moving the rod F to the left, but this can be prevented by the engagement of a pivoted arm J, Fig. 4, with a projection I fixed to, or formed in one with, the rod F, and having an extension i parallel to the rod. On a cage coming to the top of the shaft, it raises a sliding frame C, connected to an angle-lever N, to one arm of which is pivoted a rod P connected by a slotted link R and pin to the other arm. The rod P is thus moved to throw over the arm J on to the extension i, which, as the kips close under the cage, supports the arm till it locks over the projection I. When the man in charge of the cage is ready, he turns back the arm J by means of a rope Z-the link R having raised the rod P to allow of this-and then, and only then, can the engine man move the cages. The connection between the lever N and frame C comprises a split spring fork U, which yields to undue pressure and which engages a pin T placed in one of a series of holes. Alternatively, the lever N may be operated by projections on the cages. The lock may be put out of action by placing a block V on a lug W.

Abstract: 17,224. Audiffren, M. Jan..27, [date applied for under Patents Act, A.D. 1901]. Decanting and settling. -Relates to means, forming part of rotary refrigerating-apparatus employing sulphur dioxide, for separating and recovering the lubricating-oil from the mixture of liquid sulphur dioxide and oil which is formed, by allowing it to settle into layers. In the condenser A are fixed discs E, F, in bearings in which hangs a shaft G held in place by a weight H, and the piston I of a compressor fixed to the disc E is pivoted eccentrically on and operated by the shaft, so that the compresser draws vapour from the refrigerator B through the axial tube D. From the end of this tube is suspended a box K, by means of a collar M and arm L. Any liquid in the vessel A is thrown outwards and collects in a gutter a, whence it is removed through a pipe, being forced therethrough by the greater pressure in the vessel A, and finally falling into the vessel B. Thence, it is forced into a gutter b, and is caught by a blade o and allowed to pass through a funnel into the box K. Here the liquid settles into layers, the sulphur dioxide passing out through the tube k and the oil being drawn through the openings l and tube D along with the vapour and passing back into the condenser A. In cases where the speed of the apparatus is insufficient to maintain the liquid in the gutter b, a spiral blade S gathers and guides it into the separating-box K.

Granted: 1905-09-07
Abstract: 24,083. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Nov. 7. Cellulose acetates.-Cellulose, whether mercerized or not, is acetylated either by treating it in a damp state with an acetylating-agent and a suitable acid, or by treating it, whether damp or not, with a mixture of acetylating-agent, acid, and a quantity of a neutral body sufficient to prevent the mixture from dissolving acetylated cellulose. According to the Provisional Specification, hydrocellulose may also be used. In an example, cotton, free from grease, is soaked in water or dilute sulphuric acid, pressed until it contains only 20 per cent. of water or acid, and digested with acetic anhydride and concentrated sulphuric acid. The product is suitably separated from the thick liquid obtained. Acetic anhydride may be replaced by acetyl chloride, and, instead of sulphuric acid, an organic sulphonic acid or a phosphoric acid may be used. In other examples, cellulose, whether previously damped with water or acid as described above or not, is acetylated with mixtures of acetic anhydride, sulphuric acid, and benzene, toluene, or ether. The product resembles cottonwool in appearance, but is brittle and hard to the touch. It dissolves in chloroform and in acetone but not in water.

Abstract: 28,762. Mellinger, G. B., Skemp, R., and Stauffer, J. R. Dec. 29. Bending; rolling.-Skelps are bent and shaped by feeding them through a succession of rolls and passes to form lap or butt jointed tubes, the normal tendency of which is to contract. The machine has seven pairs of rolls 3, 4, 5, 6, 7, 8, 9, each of which is shown detached in Figs. 9, 10,11,12,13, 14, and 15 respectively, while the last three are shown in their relative positions in Fig. 4. The lower spindles of alternate pairs of rolls are driven directly from the power shaft by bevel and spur gearing, the upper spindles being driven from the lower by spur gearing. On leaving the roll 9, the tube passes between guide-rollers 24, 25 and the flexing-rollers 26, 27, 28, 29, 30, which depress one edge, as shown in Fig. 16. The skelp is then coiled and the edges closed by being fed through a pass formed by four adjustable grooved rollers 33, 34, 35, 36, Figs. 4 and 17. This completes a tube with a lap seam, and, if it is required to be butt jointed, it is passed over a supported mandrel 45, Fig. 7, tapered in the part 45<c> and having a rotary die 51 or pivoted plate which flexes one edge outwards, as shown in Fig. 19. As the tube passes over the die &c., the outwardly-deflected edge springs back flush with the adjacent edge and with a tendency to close against it. The tube is straightened by horizontal and vertical rollers (not shown).
