Title: Improvements in Valves for Engines.
Inventor: HAY ALEXANDER GEBBIE
Filed: 1898-03-31
Granted: 1898-05-07
Abstract: 7737. Hay, A. G. March 31. Valves, distributing; cylinders.-Two forms of slide valve are described, both of which work in a chest or jacket surrounding the cylinder. One of these consists of a pair of packed rings G working between the cylinder liner and cylinder casting and connected by rods H. These act like ordinary D-valves, steam being admitted from the spaces K at each end and being exhausted from the intermediate space L. The valves of two cylinders in a multiple-expansion engine when thus constructed may be connected together by a yoke J. In the second form of the invention, the cylinder liner is eccentric to the cylinder casting, and the valves R, instead of being complete rings, are in the form of portions of a crescent as shown in plan in Fig. 5. The invention is especially applicable to marine engines.

Title: Improvements in the Manufacture of Bricks, Tiles, Blocks and such like Articles from Plastic and Powdered Substances.
Inventor: STANLEY REGINALD
Filed: 1899-09-12
Granted: 1900-09-12
Abstract: 18,442. Stanley, R. Sept 12. Moulding bricks, tiles, blocks, &c.-A coating of clay slip, oxide of iron, or oxide of manganese, sometimes with the addition of a lubricating or other liquid, is injected into the mould of the press before the rough block or material is inserted therein, in order to produce a surface of the required colour, vitrification, or finish, and allow inferior clay to be used for the body. In the arrangement shown in Fig. 1, slip is supplied to a feed-chamber f by a vessel h, and is forced through a pipe f<1> and perforated lining plates of the mould by an air or steam current supplied by pipes e<2>, e'. A valve h<1>, controlling the supply of slip to the chamber, is operated by a cam a, rod c, lever d, and springs c', h<2>. A valve e is opened by the lever d so as to admit compressed air or steam to the chamber after the valve A' is closed, and is released and closed by a spring e<3>, before the valve h<1> is opened again. When the material supplied to the mould is in a semi-dry, powdered, state, a strip r is fitted inside the feed-box E to delay the feeding of material until the mould has been sprayed. The feed - pipe f<1> communicates with longitudinal passages k which communicate with grooves in an upper block or frame g<1>, fitted with perforated spray plates g<2>. In a modification for supplying coloured dust, the feed of dust to the chamber is regulated by a horizontal sliding plate or valve which is operated by a lever and a horizontal sliding rod which is acted on by wedges or cams fixed to the vertical rod c. In another arrangement, for spraying slip on the sides and bottom of the mould, the slip is supplied through passages p<2> to upper channels p, Fig. 7, by a force-pump, and is injected through spray plates by compressed air or steam. The force-pump and air valve are actuated by a lever which is pivoted to a slotted plate or rod carrying rollers which are acted on by cams on the main driving-shaft. The invention is applicable to presses of the type described in Specification No. 7297, A.D. 1898, and to other machines. The slip may be caused to run down the sides of the mould from the top, or dust may be forced through a nozzle into the mould, or the invention may be employed for the single purpose of lubricating moulds.

Patent GB-190004278-A (GB)
Title: Improvements in Controlling Governors for Marine and other Engines.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1900-03-06
Granted: 1900-07-07
Abstract: 4278. Thompson, W. P., [Sperry, E. A., and Haines, G. A.]. March 6. Governing and regulating.-Relates to a system and apparatus for governing marine and other engines by applying with graduated force an electromagnetic or other brake acting either alone or in conjunction with means for regulating the throttle valve ; also to means for releasing the brake and for absorbing the beat produced. Fig. 1 shows a marine engine with one form of electromagnetic brake. The stationary electromagnet 6 is arranged in juxtaposition to the disc 5 on the engine shaft, and is energized to a greater or less extent automatically so as to maintain a constant load on the engine. The electromagnet is in the form of a ring with a series of circular grooves in the face and transverse or radial grooves connecting the circular grooves, having sector-like projections N, S round which the windings are disposed on three sides only, as shown in Fig. 5. Cavities 97 may be provided in the ring, through which water is circulated for cooling purposes. Two or more such brakes, or band or other mechanical brakes, may be employed. The action of the brakes, and of the throttle valve if desired, is regulated by a centrifugal governor driven by gear 4<1> from the engine shaft and contained, along with various electrical controlling-apparatus, in the box 1. Fig. 3 shows diagrammatically in plan on an enlarged scale the contents of the said box. The centrifugal governor 2 is in two parts, which are linked together so as to check irregular action. Through an arm 30 the governor 2, as it expands, operates to close in succession a series of circuits containing electromagnets 34, 35, 36 which release mechanically-driven switches 42,43,44 controlling the brake circuits, The mechanical actuation of the switches is'effected by loose cords 41 passing over pulleys on a constantly-rotating shaft. The switch pulleys are held by detents except when, by the action of one or other of the electromagnets 34, 35, 36, one of them is allowed to make a limited movement. The switch 42 is revolved for making and breaking (and reversing) the main current in the brakes, while the switches 43 and 44 are for cutting out or in resistances 60 and 61 from the main circuit so as to regulate a more intense action. An additional electromagnetic detent and escapement device (not shown in Fig. 3) is provided in connection with the switch 42 for reversing the current through the resistance 59 and thereby releasing the brake. The arrangement shown also comprises a steam-relay cylinder 15 for adjusting the engine throttle valve. The valve rod 90 of the relay cylinder is operated by electromagnets in the circuits, which, as already indicated, are controlled by the centrifugal governor.

Title: Improvements in Electric Railways on a Sectional Conductor or like System.
Filed: 1901-06-04
Granted: 1901-08-17
Abstract: 11,408. British Thomson-Houston Co., [Stewart, S. B.]. June 4. Electric railways and tramways on sectional conductor or like systems with electromagnetic switches. Switches.-In order to reduce the current through the operating-coil of the section switches after they are closed, resistances, carried on the vehicle, are thrown into the circuit. Means are also provided for initially exciting the switches to restore the main current. The invention is shown as applied to a system with two sets of collecting-shoes C and sectional conductors L having coils P excited by a shunt from the main for picking up and holding the switches. The main current from the main live section passes through the coils 0<1> or 0<2>, thereby putting the resistance R' or R into the shunt circuit to the corresponding switch or cutting out the resistances when no current is flowing. If both switches are excited, the coils hold their plungers in the mid position. When starting, a spring I causes the plungers to cut out the resistance from a separate source of supply G, which is in shunt with the motor circuit. This may consist of a shunt-wound generator driven by an air motor and protected from the main current by a resistance r. The valve V which turns on the air also carries a switch to throw the motor into the circuit.
