Patent GB-189913553-A (GB)
Title: Improvements in Engines in which Steam or other Fluid Pressure is Transmitted from Cylinder to Cylinder to be Used Expensively.
Inventor: WILSON THOMAS
Filed: 1899-06-30
Granted: 1900-06-30
Abstract: 13,553. Wilson, T. June 30. Compound and multiple-expansion engines; cycles or systems of working; valves, distributing and reversing.-Relates to a cycle or succession of expansions in multi-cylinder engines, designed to prevent the exhaust from being locked in the cylinder and to reduce back-pressure notwithstanding variations in the grade of expansion. In a four-cylinder engine, during the first half of the stroke, the exhaust from the high-pressure cylinder is divided between the second and third stage cylinders, the exhaust from which is combined for use in the low-pressure cylinder ; during the second half of the stroke, boiler steam is divided between the first and second stage cylinders, and the combined exhaust from them is supplied to the third and fourth ; the same succession of operations is then continuously repeated. By means of a reversing-valve, the succession of operations is changed so as to produce reverse running. In this case the exhaust of the first cylinder is divided between the opposite ends of the second and third during the first half stroke, while the exhaust from the second and third is supplied to the fourth-stage cylinder, and, during the second half of the stroke, live steam is divided between the first and second cylinders, the exhausts from which are combined and supplied to the third and fourth. The Specification shows examples of the valve arrangements employed in two-cylinder and in threecylinder engines. Figs. 9 and 11 show sections through an apparatus having two cylinders. The high-pressure cylinder A is furnished with two sets of admission and exhaust ports controlled by separately-worked valves b<1>, b', preferably in the form of piston valves, one b<1> arranged to work with constant and the other b<2> with variable cut-off. At the back of these valves is a valve-chest with cross-over ports controlled by a rotary plug change or reversing valve e. The latter valve is for producing the change in the cycle indicated above which is required to take place on reversal. The distinctive features of each form of the cycle are due to the joint motion of the two valves b<1>, b<2>. Figs. 17, 18, and 18<A> show one example of a single distributing-valve suitable for use in place of the three valves b<1>, b<2>, e which itself contains a crossover passage. This is brought into use for the purpose of reversing by turning the valve i through a right-angle by means of the handle o through which the squared valve spindle passes.

Title: Improvements in Aluminium Alloys and in the Method of Casting them.
Inventor: MCADAMS WILLIAM ALBERT
Filed: 1899-10-23
Granted: 1899-12-09
Abstract: 21,137. McAdams, W. A., and Book, D. D. Oct. 23. Casting.-Relates to aluminium alloys and the method of casting them, and particularly to alloys in which aluminium predominates, and which also contain zinc or copper, or both, with or without a small percentage of nickel. In casting such an alloy, the molten mass is cooled at such a rate that the zinc and copper are not permitted to segregate or crystallize out, thereby obtaining a homogeneous casting. This is accomplished, in the case of thin or small castings, by using a metal mould of sufficient thickness to remove the heat quickly, and, when the casting is to be thick, the mould may be surrounded by a cooling-medium.

Title: Improvements in Gas Meters.
Inventor: LECKBAND THEODOR HANS JURGEN
Filed: 1900-03-13
Granted: 1900-06-23
Abstract: 4739. Leckband, T. H. J. March 13. Meters.-Two similar gas holders are supported on one base-plate, and the connections are so arranged that, while one holder is delivering gas, the other is receiving it. When the first becomes empty, it automatically reverses the connections &c. In the example shown, the supply pipe 42 leads to a cross-pipe 18, having two short depending tubes 19, 20, each with a central partition 21. The tubes dip into liquid seals 14, 15 carried upon a lever 17. In the position shown, the incoming gas passes by the tube 9 to the holder 4<a>. At the same time, gas from the holder 4 passes by the tube 8 to the outlet tube 11, the cross-tube 8, 9 being provided with liquid seals similar to those on the tube 18. When the holder 4 is empty, an adjustable lever 25, carrying a weight 27, is caused by the flange 29 to force down an arm 30, whereby the lever 17 is thrown over, a weight 34 ensuring the complete movement. A connecting-link 41 immediately reverses the lever 16. The connections now cause the gas from the supply pipe to pass to the holder 4, while that from the holder 4<a> passes to the outlet tube 11. The two bells are connected together by a lever 37, so as to limit their movements and to equalize the pressure. In a modification illustrated, instead of the arrangement of tubes and levers a solid casting is used, having passages therein, and a depending tube at each corner dipping into a liquid seal carried on a pivoted frame. A counting-device is attached in either case.

Filed: 1900-05-18
Granted: 1900-07-28
Abstract: 9192. Wilson, J. T. May 18. Valves, distributing; pistons.-The object is to prevent the spring rings used in piston distributing- valves from being collapsed under the pressure of the working steam, or from being caused to exert excessive pressure against the valve chest by the means adapted to prevent such collapse. To this end the said rings are rendered rigid during working, although still free to expand while the working pressure is not in action. Fig. 1 shows one form of the invention. The spring rings H are lodged in grooves at the ends of the valve body D, and on the steam side are acted on by wedge rings J. The pressure of the steam on these rings has the effect of locking the spring rings.

Title: Improvements relating to Repeating Mechanism for Clocks.
Inventor: BAILEY HARLOW WARD
Filed: 1901-01-04
Granted: 1902-01-04
Abstract: 259. Bailey, H. W., and Parkinson, W. J. Jan. 4. Repeating - mechanism; striking - mechanism. - Fig. 1 is a front view with the dial removed, Fig. 5 a horizontal cross-section looking upwards, and Figs. 2 and 13 front views of details. Hours, quarters, and minutes are struck on a single bell 132, as the passing teeth of three racks 47, 35, and 23 push three slotted and sliding triggers 117 successively up against the three tails 129 of the single hammer 130. The operation is effected by a lever 10, 14, the outer arm 10 of which is pushed down a slot in the casing to wind up a spring, and is then released. In the push movement, the inner arm 14 lifts a bent lever 109, which disengages the rack hooks 99 to let the racks fall to the snails 87, 75, and 73. In the return movement, a combined hook and cam 17, 15, pivoted on the inner arm 14 of the operating-lever, takes hold of a pin 50 on the hour rack 47, and after the hours have been struck is tripped away by passing a stationary pin 137. A corresponding pin 41, on the quarter rack 35, and another 30 on the minute rack 23, enable them to be similarly operated, and the cam encounters two other stationary pins 138, 139. The quarter hour and minute snails 75, 73, and a disc 68 bearing three dog teeth 71, turn together with a disc 63 fast upon the centre arbor, but jump at the quarters because the dog teeth encounter a spring finger, and the connection of the two discs is that of a pin 72 in a short slot 65. A spring 66 in a circular groove 64 in the fast disc bears on the pin in the slot. At the hour a pawl 80, pivoted on the quarter snail 75 and overlapping it, encounters a fixed bracket 144, and is thereby applied to one of the twelve teeth of a disc 86, Fig. 5, attached to the hour snail. Thus driven, the hour snail jumps under the action of a pawl bearing on a star-wheel 90, while the quarter and minute snails also jump because the spring in the fast disc is compressed till the hour snail jumps. Motionwork.-The motionwork is adapted to accommodate the repeating - mechanism, by lengthening the arbors between the pairs of wheels and pinions.
