Patent GB-190302104-A (GB)
Title: Improvements in Pressure Indicators
Inventor: DION MARQUIS ALBERT DE
Filed: 1903-01-28
Granted: 1903-12-03
Abstract: 2104. Dion, Marquis A. de, and Bouton, G. Jan. 23. Steam-engine indicators.-An indicator, specially applicable to highspeed motors, communicates with the cylinder through a valve which opens for only a short time at a certain point in each stroke, giving either a steady indication or the ordinary diagram by varying continuously the period of communication. Fig. 1 shows a section of the valve and differential gear. The shaft a, rotating at the same speed as the motor, carries a bevel-wheel b gearing with two others b<1>, d' carried by a disc c mounted loosely on the shaft a. A bevel-wheel d keyed on a shaft e, co-axial with the first, also gears with the wheels b<1>, d'. A small projection on the disc c raises at each rotation the stem g of an equilibrium valve i, j, through the medium of a lever f. The upper space is connected by the tube h to the motor cylinder ; the space m is connected to the indicator. The shaft e being stationary, the disc c, rotating at half the speed of the motor, will open the valve and transmit the pressure to the indicator at every second revolution, i.e., once in each cycle, at exactly the same point in each stroke. By slowly turning the shaft e by hand, the point of opening will vary continuously. A worm-wheel fixed on the shaft e is turned by a worm and handle for the purpose. The shaft e is also fitted with a crank for reciprocating the frame which carries the indicator card. The motion is communicated to the frame by a connecting-rod, the length of which is to that of the above crank in the same ratio as the lengths of the connecting-rod and crank of the engine. Or instead of using a connecting-rod, the crank-pin 9 may, as shown in Fig. 4, bear against a piece r curved to the same radius less that of the crank-pin, the spring W keeping the two in contact. In either case the motion of the frame is exactly proportional to that of the piston, the connecting-rod or templet being varied to suit different engines. The frame X runs on rollers V along a track, and carries the indicator card in the stays y. A diagram showing the variation of pressure at a certain point of the stroke during successive strokes may be obtained by keeping the shaft e stationary in the desired position and moving the indicator card uniformly. When it is required to open the valve once every revolution, a cam is arranged on a disc fixed on the shaft e, and the disc c is arranged to be rotated by hand, by means of worm-wheel gearing. Thus, when the disc c is stationary, the shaft e rotates at the same speed as the motor. The position of the parts is altered so that the valve-rod comes over the new cam-disc.

Title: Improvements in Strength Testing Machines.
Inventor: BARR GEORGE RICHARD
Filed: 1903-03-06
Granted: 1903-06-11
Abstract: 5282. Barr, G. R. March 6. Dynamometers, for physical strength-testing, preferably of the coin-freed type. A coin, when inserted in the shoot e<1>, falls on a lever d and by its weight lifts a detent d<2> from out of a notch in a flange on a shaft c, fitted with a handle and with a spring and chain d, c<3>. On turning the shaft c against the action of the spring, a cam f<1> acts on a slide f and displaces the hinged part d<3> of the lever d, and allows the coin to drop on to a step e<2> below a hinged hopper e<3>. If sufficient strength is exerted, another cam g<1>, by means of a slide g, tilts the hopper e<3> and allows the coin to drop out of the hopper h and be returned. If insufficient strength is exerted, the coin remains on the step e<2> until another coin is inserted. The pressure on the slit necessary to insert a coin slightly tilts the shoot and allows it to move away from the step sufficiently to allow the coin to drop off the step e<2>. Cords k, l on quadrants q, q<1> are connected to a dial and to an indicating-figure m.

Title: Improvements in or connected with Devices for Measuring the Fluctuations of Pressure in Pipes or the like.
Inventor: GEHRE MAX
Filed: 1903-03-25
Granted: 1904-03-25
Abstract: 6934. Gehre, M. March 25. Pressure gauges for measuring the fluctuations in the pressure of air, steam, or other fluid in a pipe. The pressures in two lengths of the pipe k<1>, k<2>, separated by a constriction, are transmitted through pipes d, e to a vessel a containing a bell piston c, the movements of which operate the indicating-devices by means of a rod. The lower edge of the bell c works in a mercury seal, and the vessel a is filled with water, so that, if the pressure in the pipes kl, d increases rapidly, the bell c closes the valve v, thus trapping the water in the bell, and preventing the mercury from passing into the pipe e. To prevent the movements of the water columns in the pipes d, e from affecting the measurements, the pipes are fitted with enlargements f, f<1>, which are preferably made in one vessel, as shown, and are fitted with overflows s.
Patent GB-190306986-A (GB)
Title: Improvements in Gate- Sluice- or Fullway Valves
Inventor: HOLGATE CHARLES HENZELL
Filed: 1903-03-26
Granted: 1904-01-28
Abstract: 6986. Holgate, C. H. March 26. Sliding valves.-Relates to sluice valves of the type in which two metal discs slide over the internal faces of the valves. These discs are pressed apart by wedges which come into action as the valve is completely closed, and thus serve to tighten the discs on their seats. Figs. 1 and 2 show sectional views of a valve. The discs c slide over the faces d and have inclined faces on their backs, which come in contact with the wedges e on the bridge-piece f which rests on a projection a in the valve casing b. This projection may be fixed or movable. In the latter case the piece a is held in position by a pin h working in a slot in the stop a, the bridge being then unnecessary, as shown in Fig. 4. The simultaneous action of the wedges is thus ensured. Fig. 6 shows an arrangement in which uniform tightness of the valve is ensured by having separate blocks i acted upon by the wedge w. The surfaces of contact m of these blocks i and the valve discs c are parts of spherical surfaces shown by the dotted lines n. Fig. 7 shows a modification, in which the seats of the valve are inclined and the spherical surfaces are made on the discs c. The Provisional Specification states that the backs of the valves may be made arched or flat-domed shape, and the sides of the wedge surfaces of double armature. The wedges act nearer the edges than the centres of the discs, and are connected by a U-shaped piece of metal, acting in a similar way to the above-described bridge-piece.

Title: Improvements in and relating to Electrically-operated Valves specially applicable to Turbines.
Filed: 1903-10-28
Granted: 1904-10-20
Abstract: 23,355. Warwick Machinery Co., [General Electric Co.]. Oct. 28. Steam &c. turbines.-Relates to a piston-actuated valve for controlling the supply of steam to the nozzle of a steam turbine. A subsidiary valve is operated by an electric current to modify the pressure on one side of the piston. In Fig. 1, the passage of steam through the main 7 is controlled by a butterfly valve 7<1> which is pulled down by a weight 8 when the catch 9 is tripped by a governor. After passing the valve 7<1>, the steam can pass either by the valve 10 to a nozzle 5 of the steam-chest, or through passages 13, 14, 16, 17 to the upper side of the valve piston 12. In the wider passage or steam-chamber 16, is an auxiliary valve 18 which is double ended and seats either below to close the passage 14, or above to close a passage 20 leading to an exhaust chamber 21. The spindle 23 of the auxiliary valve slides vertically in a tube 22 in which the passage 20 is made and which passes up through the exhaust chamber. To open the valve 10, the core 25 and casing of an electromagnet held above by supports 35, are energized by a coil 24, thereby dragging down an armature 26 and its spindle 27 which is normally kept raised by a spring 28. The lower end of the armature spindle thus drives down the valve spindle 23 against a spring 19 closing the passage 14 and opening the passage 20 to exhaust. Boiler steam which had occupied the space 11 above the piston 12 escapes through the passage 20 and the piston the area of which is greater than that of its valve is raised against a depressing spring 37, opening the valve 10. The flanges of the magnet core piece 25 are perforated to afford ventilation to the coil. The upward movement of the valve piston is cushioned by an arched resilient washer 36 in the piston cylinder. Several valves of the above description are mounted on the steam-chest of the turbine, a throttle valve being arranged at the end, the object being by this means to compensate for minor variations in load.
