Patent GB-190018660-A (GB)
Title: Improvements in Brake Apparatus for Railway and like Vehicles
Inventor: GEORGOFF JORDAN
Filed: 1900-10-18
Granted: 1901-04-20
Abstract: 18,660. Georgoff, J. Oct. 18. Brakes, air. Relates to means for regulating the maximum pressure exerted on Westinghouse brake pistons. Fig. 3 shows a valve, fitted between the triple valve and the auxiliary reservoir and brake cylinder, having an eccentric c' mounted on a cross-shaft I<1>, which has handles at the sides of the vehicle. This valve has passages b, c and a, d affording communication between the triple valve and the auxiliary reservoir or brake cylinder respectively, and differential pistons a, a<2> mounted on the rod a<3>. When the vehicle is fully loaded, the eccentric c<1> is in the position shown, and the check valve k is held open by the tail-rod h, but, should the load be decreased, the shaft I' is turned so that the valve k is allowed to close. Assuming there is pressure in the passage b, c but none in the passage d, air passes through the passage g to the space s between the pistons, and lifts them, thereby holding the valve k open. When the triple valve opens communication between the auxiliary reservoir and the passage a through the passage b, c, air passes through the port n and, acting on the top of the piston a<1>, forces it down, and the valve k closes, any further supply of air to the brake cylinder through the passage d being cut off. As soon as the triple valve lowers the pressure in the passage a, the valve k rises and exhausts the brake cylinder, and at the same time the pistons rise and the valve k is held open. In a modification, the weight of the vehicle is used to control automatically the pressure in the brake cylinder. As shown in Fig. 7, the weight is applied at q to the lever u, which is linked to a pivoted lever I one arm of which bears on the shank o' of the single piston o arranged in the casing R. The action of this device is somewhat similar to that already described, but in this case the tail-rod holds the check valve open until the pressure above the piston o is sufficient to force it down against the counter pressure of the lever I.

Abstract: 2248. Lake, H. H., [Fulton, W. E.]. Feb. 1. Drawing.-A continuous wire-drawing machine is made up of sections, such as are shown at A', A<2>, Fig. 1. Each section is provided with die-holders a<1> and drawing-rolls n driven at the required speeds from the shaft c by bevel gearing a<7>. After passing through the last die, the wire is wound round a drum G. The rolls rotate in lubricating-fluid contained in troughs a<3> and circulated by a pump B. The machine is stopped by disengaging a clutch from the driving-pulley c<1>. The clutch is operated by a foot-lever c<4> on a rockshaft d<6>, having a crank d<5> to which is connected a rod d'. The rod d<4> is pivoted to toggle-levers d<3>, Fig. 5, operating a lever d<2>, which, when the clutch is disengaged, raises a brake rod d' and shoe d to act on a pulley D on the shaft c. When the clutch is engaged, the brake shoe is lowered. For threading the dies on the wire, a chain F, driven by spur and sprocket gearing from the shaft c, draws a pair of gripping-jaws E along a track e, the first die being placed in a bolder f<10>. After drawing a sufficient length the second die is threaded, and the first is placed in the first dieholder a', a few turns of wire are coiled round the roll a, and the second die is placed in the second holder.

Title: Improvements in or in connection with Direct Acting Engines Applicable for Coal Cutting, Mining, Drilling, Tunnelling, Stamping Ore, Pile Driving, and the like.
Inventor: WRIGHTSON THOMAS
Filed: 1901-05-13
Granted: 1902-04-17
Abstract: 9911. Wrightson, Sir T., and Morison, J. May 13. Rock drills; undercutting &c.-Relates to directacting engines worked by air or other fluid-pressure and applicable for coal cutting, mining, rockdrilling, and the like. The machine is of the reciprocating percussive type and is formed with two cylinders side by side, each actuating a pick or tool and acting alternately. Fig. 1 shows in plan a swinging pick machine embodying the invention, and Fig. 3 shows the arms in vertical section. The pistons in the working cylinders a, b are connected by rods to smaller pistons in openended cylinders c, d projecting from the front ends of the main cylinders. The forward strokes are effected by admitting the motive agent to the rear ends of the larger cylinders, and the return stroke by fluid under pressure acting in the space between the two pistons, to which it has access continually. The arrangement of double pistons enables stuffing-boxes to be dispensed with, and the pistons can give a free blow. The distribution of the motive agent to the two main cylinders is effected by a vertically-moving slide valve as shown in section in Fig. 4, working in a casing m at the rear end of the cylinders and actuated by pistons p, p. The fluid for operating these pistons is admitted from the space between one pair of pistons to one end of the valve chamber m by one of the pipes u or v while it is being exhausted from the other end by the other pipe. The alternate admission and exhaust through these tubes is caused by the passage to and fro of the smaller pistons over their orifices which are situated near the front ends of the small cylinders. The cushioning of the pistons at the end of the backward stroke is provided for by the positions of the several ports. For cushioning in the forward stroke, a diaphragm H is inserted between the larger and smaller cylinders, and communication between the spaces on opposite sides during the greater part of the stroke is provided for by a groove in the piston-rod, which groove is not made to extend as far as the rear piston. The above construction with two cylinders allows the piston to make either long or short strokes, and yet always ensures their return ; there is also no dead point in the machine, and the simultaneous and opposite movements of the picks tend to balance the machine, and, if one pick gets fixed, to free it.

Granted: 1903-03-19
Abstract: 9327. Howard, H. E., and Hadley, G. April 22. Iron hydrates and oxides; zinc carbonate, hydrate, and oxide.-The spent hydrochloric acid from galvanizing-works, or similar liquid, is neutralized with impure zinc oxide or metallic zinc, such as the residues, contaminated with lead, from galvanizing- works. The solution obtained is heated by live steam and the iron oxidized to the ferric state and precipitated as hydrate by successively adding milk of bleaching-powder, and milk of lime or its equivalent. The ferric hydrate settles, and is removed, filtered, washed, and afterwards heated to obtain red pigments. The solution is treated with a further supply of milk of lime to precipitate all the zinc as hydrate, which may be dried to form oxide, or distilled to obtain chemically-pure zinc. The calcium-chloride solution is used to hydrate the quick-line for the next batch. When the calcium-chloride solution becomes sufficiently concentrated, it is evaporated to obtain that salt. The Provisional Specification states that the zinc may be precipitated as carbonate.

Title: Improvements in Apparatus for Raising Liquids by Means of Compressed Air.
Inventor: STARRETT DANVILLE WILLIAM
Filed: 1903-08-13
Granted: 1904-07-14
Abstract: 17,583. Starrett, D. W. Aug. 13. Raising liquids by aerating ascending column. - Relates to apparatus for raising or propelling water or other liquid and consists of means for raising the liquid to a greater height without proportionately increasing the pressure of the compressed air used. Fig. 2 shows a sectional elevation of one form of the apparatus, and Figs. 3 and 4 similar views of the parts of a modification. In Fig. 2 are shown the air-compressing pump 1, the pipes 3, which connect the pump with the chambers 4 and, through automatic valves 11, with the pipes 8, the delivery pipe 9, and the suction pipe 5. Upon starting the apparatus, liquid is drawn into the chambers 4 and a portion of the pipes 3 during the suction strokes of the compressor, and is forced into the pipes 8 during the reverse strokes. As the liquid pressure on the valves 11 is less than that on the valves 10, the compressed air will, at the beginning of the compression stroke of the pump, pass through the valves 11 and force the liquid up the delivery pipe. As soon as the pressure on the valves 10 has been slightly relieved by liquid being forced out at the top of the delivery pipe, the valves 10 are forced open, and more liquid is driven into the pipe 8. The height to which the liquid can be forced depends upon the quantity of air interspaced between the different portions of liquid, and this, in turn, depends upon the amount the valves 11 are allowed to open. The modification shown in Figs. 3 and 4 is formed with only one chamber 19 for the liquid passing from the suction pipe 22, and the pipe connecting this chamber with the air - compressing pump is carried down inside the delivery pipe, as shown at 13. The valve 30 corresponds to the valves 11, Fig. 2. The pump 1 is connected to the pipe 13 through a valve 15, which is automatically actuated by the projection 16 on the piston-rod. The apparatus may be used for deep wells or mines.
