Patent GB-190407861-A (GB)
Title: Improvements in and relating to Hydraulic Relay Apparatus.
Inventor: WARREN HENRY ELLIS
Filed: 1904-04-05
Granted: 1904-06-16
Abstract: 7861. Warren, H. E. July 7, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Actuating valves and cocks.-Relates to hydraulic relay and controlling apparatus in which a small force, applied by hand or by the governor of a steam engine &c., is applied to put into action mechanism such as valves. Fig. 2 shows one form of the invention, suitable for working hydraulic presses or lifts. The pipes f, g, h, cylinders D, C', and chamber w form a closed fluid system, and consequently any motion of the piston k<2> must be accompanied by a corresponding motion of the valve B, which projects at x into the chamber w, or of the piston e in the cylinder D. Water is admitted under pressure through the pipe o to the chamber w<1>, and also through the pipe o' to the space above the piston k<2>. When the piston is raised, the pressure of water on the end s of the valve forces the valve to the left. Water is thus admitted from the pipe u through the port r to the main cylinder A, the piston of which moves to the right, the water on the other side of the piston escaping through the port q and waste pipe t. The piston-rod d is connected to the piston-rod a by a yoke y<1> so that the piston e moves simultaneously with the piston b and consequently forces water into the chamber w, thus closing the valve again. The valve B is thus actuated so that each position of the piston k<2> corresponds to a definite position of the piston b. A narrow tube b<1> is cut in the end of the plunger x to relieve pressure in the chamber w due to the motion of the piston e. The valve k shown in Fig. 4 is specially suitable for use with a centrifugal governor, and can be applied to actuate either an apparatus such as that just described or a clutch mechanism as shown in Fig. 4. The essential difference in the application of this valve to the above apparatus is that the plungers x, s at the ends of the main valve must be of unequal area in order that the initial motion of the valve may be obtained without any actual difference of water pressure. The pipe o<1> as before connects with the water under pressure, while the pipe p connects to the waste pipe. In the application of the invention shown in Fig. 4, the motion of the piston x<1> is used to actuate a friction clutch b<2>, which, by engaging with one or other of the rotating wheels y<2>, y<3>, imparts motion to the shaft a<1>. In this case, the piston e is actuated by a screw passing through the hub of a spur-wheel a<4>. In another modification of the invention, instead of there being a constant fluid pressure at w<1>, a four-way valve is used to direct the water under pressure to either side of the valve. In this case, the cylinder D is double-ended, water being forced from either end to the chambers w, w<1> respectively.

Title: Improvements relating to Flash Boilers
Inventor: CAROLAN EDGAR ALFRED
Filed: 1904-07-22
Granted: 1905-06-29
Abstract: 16,259. Carolan, E. A., [General Electric Co.]. July 22. Plunger pumps; hand pumps; actuating pumps; stroke, varying.-In order to adapt steam generation to the varying conditions of demand, excess of feedwater is passed to an accumulator, from which it may be drawn as occasion requires; means are also provided for delivering fuel and water to the burners and boiler, respectively, in definite relations. The arrangement of the system is shown diagrammatically. A flash boiler of suitable construction and contained within the casing 4 supplies steam to the engine 2. Water for the system is supplied from the tank 9, between which and the boiler the power-driven pump is situated. The effective delivery of the pump is altered by varying its stroke according to the conditions of working of the generator. The pump is driven by the eccentric 11, which is connected to the pump through the elastic or yielding medium 12. As the pressure in the boiler increases, the stroke of the pump proportionally shortens, and the balance of the movement of the eccentric is absorbed by the elastic medium. The plunger of the pump is withdrawn from the cylinder by the extension springs 14. To start the system, the manuallyoperated water pump 17 is employed, the valves of both pumps being arranged in the feed-pipe. Between the pumps and the boiler is provided the accumulator. Its contents are passed to the boiler by way of the pipe 24 upon the opening by hand of the valve 25. When the demand upon the boiler ceases, the pressure rises, with the result that water and steam are automatically forced back into the accumulator, the valve 23 being raised. Similarly, on the boiler using little water, excess of feed passes into the accumulator. On the boiler being required to come into full operation, the accumulator may be drawn upon for an immediate supply under pressure. To increase the pressure in the accumulator, the air pump 27 forces air into the accumulator. Sufficient water is always retained in the accumulator to form a liquid seal. The air pump is driven from the eccentric 11 through the elastic medium 12. A manually-actuated air pump may be attached to the valve 31, when the pump 27 is not working, for producing initial pressure. The relief valve 32, set at the desired pressure, is fitted for returning when necessary excess of water to the tank. As regards the fuel supply for the burner, the fuel is initially forced out of the tank 33 by the handpump 34. The pump 35 is also employed. It is operated from the eccentric 11 through the flexible medium 12 in such a manner that, when the pressure in the burner is too great, the pump 35 refuses to act. The outward stroke of the pump is effected by the springs 14.

The plate may be prepared as follows :-A sheet of lithographic zinc is coated with bichromated albumen, gum, gelatine, or other sensitized medium, dried and exposed under a half-tone positive made as described in the Specification quoted above. After exposure, it is rolled up with lithographic ink, developed in cold water, and gummed up. After drying, it is damped and rolled up with stiff lithographic ink and dusted with bitumen, dragon's blood, French chalk, or other powder. The plate is then etched with nitric acid, washed and dried, and cleaned with turpentine, leaving the plate in intaglio with the hollows clean zinc, and the surface retaining its albumen coating. Bitumen, resin, or other similar powder is dusted over the whole plate and the surplus wiped off, and the plate is heated just to melt the powder. The albumen is then removed in a bath of caustic potash and the clean zinc surface gummed up, and when the gum is dry the bitumen or other powder is dissolved out of the hollows by benzole, turpentine, or other solvent. Lithographic transfer ink is then dabbed into the clean hollows and the surface washed with gum and water. The plate is printed in a hand lithographic press or a machine having a flat or curved surface. The surface of the plate is kept clean by periodic damping with water or glycerine and water, or by similar methods. Instead of metal plates, stone may be employed.

Title: Improvements in or relating to Conveyors.
Inventor: BOULT ALFRED JULIUS
Filed: 1906-03-05
Granted: 1906-08-16
Abstract: 5363. Boult, A. J., [Anderson, C. H.]. March 5. Conveyers.-Relates to belt-supporting devices which permit the belt to adapt itself to a flat or concave surface according to the articles being conveyed. The longitudinal girders A of the conveyer frame are connected at intervals by pairs of cross-braces B bent downward at the central portion. On the braces B are journal boxes a receiving trunnions C formed with bearings c for the shafts D of the conveyer rollers E. The shafts D are cut away at their outer ends to rest on the beams A when in the horizontal position. The rollers E are in two parts, and are journaled on the shafts D by sleeves and are retained by collars. When a box of greater width than the distance between the bearings a is being conveyed along the band, it will so bear upon the rollers that they assume an horizontal position, while a barrel will cause the band to assume a more or less concave form, as shown by the dotted lines in Fig. 2. Articles of various forms may therefore follow each other in rapid succession along the conveyer band. Catches I<1> provided with upper shoulders I<2> to sustain the rollers in an horizontal position and catches I<3> to lock them in the troughed position may be provided. These catches are connected to a longitudinally-extending rod H, and are simultaneously operated by a lever if the flat or troughed form of belt only is required. The return run of the belt may take place over rollers G. In a modified form, a small central roller is suspended by its shaft from the inner ends of the shafts D, this shaft being such that it always maintains an horizontal position.
