Title: Improvements in and relating to Valve Controlling Devices of Plant using Elastic Working Fluid from a Plurality of Sources.
Inventor: PARSONS CHARLES ALGERNON
IPC: F01D17/14
Filed: 1912-02-07
Granted: 1913-03-07
Abstract: 3116. Parsons, Sir C. A., Carnegie, A. Q., and Parsons, G. L. Feb. 7. Regulating. - Valvecontrolling devices for plant such as turbines using g working-fluid from high and low pressure sources comprise, in respect of both high and low pressure valves, means responsive to the pressure of the low-pressure supply and additional separate means responsive to the speed-regulating gear. The low-pressure valve g is controlled, as described in Specification 6180/08, by a servomotor b having control valves a, p in parallel, actuated respectively by the speed - governor e and by the pressure on the supply side of the low-pressure valve g through a passage n and a piston m. The low-pressure also governs, through a connexion o, the similar control valve p controlling the servo-motor b of the highpressure valve j, which is also controlled similarly to the method described in the abovementioned Specification. The springs governing the valves p are adjusted so that, when the low-pressure supply is sufficient, the highpressure valve will be closed, and the lowpressure valve will remain open, and vice versa. In a modified form, the connexion o is dispensed with, and the high-pressure valve p is moved by mechanical connexion with the low-pressure valve p.

Granted: 1912-10-17
Abstract: 6311. Short, M. March 14. Washing-tanks.-In a washing-tank which is filled and emptied, or partly emptied, automatically and at regulatable periods, the water after reaching the level of a float chamber B overflows into this chamber and gradually raises a float C, which rises on a spindle d connected to the discharge plug D. The float rises until it engages an adjustable projection d<1> clamped to the spindle, thereby raising the plug D. To regulate the amount of water that intermittently escapes from the tank before the plug D closes the tank outlet, a rod E carries a screwdown needle valve, or a screw e having a tapering slot, which regulates the outlet opening b<1> of the float chamber.

Title: Improvements in Methods of and Apparatus for Raising or Forcing Liquids or Compressing Elastic Fluids.
Inventor: HUMPHREY HERBERT ALFRED
Filed: 1912-07-03
Granted: 1913-07-03
Abstract: 15,585. Humphrey, H. A., and Rusdell, W. J. July 3. Direct explosion apparatus.-In internal-combustion pumps without fly-wheels, of the type having a vertically reciprocating piston of the differential type, the inward stroke is produced or assisted by casing the piston or a part attached thereto to displace liquid by immersion during the out-stroke, so that the upward pressure of the liquid on the piston causes the piston to rise when the stroke is finished, and so that the piston will assume a desired level if the pump ceases to work. Fig. 1 shows by way of example a four-stroke cycle differential piston pump suitable for low lifts. The differential piston 2, 3, 4 is formed hollow and carries a hollow extension 6 at the bottom containing air at any desired pressure. A body of water, which may be renewed from time to time by a supply-pipe 10, is carried above the piston 2 for the purpose of cooling the combustion chamber 1, and is prevented from splashing by means of a plate 42. The bouyancy of the piston is adjusted by admitting water to the space 5. In order to assist the reciprocation of the piston, two air cushions are provided, one formed in the space 7 between the piston 4 and the cylinder cover 12, and the other in an air-bell 15 depending from the cover 13, 14 of the water-chamber 36, 37, 38. The pressure of the cushion 7 is carried below atmospheric on the down-stroke of the piston and above atmospheric on the up-stroke, any leakage being made up by the periodical opening of a port 21 by the valve 20 at the moment when the pressure is about atmospheric. The air in the cushion 15 is renewed by a snifting- valve 16. The water - suction valves 28 are arranged above the level of the water-supply aa in order that they may be accessible through a man-hole in the cover 14. The pump operates in known manner on a four-stroke cycle, water being discharged through the delivery valves 29 at each down-stroke of the piston. For high lifts, the combustion chamber may be made larger in area than the pump plunger, and the cooling- water above the piston may be dispensed with and replaced by an external water jacket as in an ordinary gas-engine. When the pump is stopped, the differential piston rises by flotation, and it is thus possible to start the apparatus by causing combustible mixture to enter the combustion chamber under sufficient pressure to depress the differential piston.

Title: Improved Sewing Machine Power Bench.
IPC: D05B69/16
Filed: 1912-07-04
Granted: 1913-04-24
Abstract: 15,622. Singer Manufacturing Co., and Corrall, H. July 4. Sewing - machines; driving; stopping - gear. non-automatic.-In a power bench carrying a number of sewing-machines driven from a rotating shaft below, all the shafts, belts, &c. are fully enclosed. The bench comprises a table 6, Fig. 7, clamped to the upper rail 4 of the legs of each section by a plate or bench strap having formed on its upper side a work shield 8 and spool stand 9. A single driving-shaft, which extends the full length of the bench, is driven either directly or through a belt connexion at one end from an electric or other motor, and is fitted under each machine with a loose belt pulley 37 carried on a stationary bush 21. Each loose pulley is driven from the rotating shaft by a friction disk 29 thereon, the pulley being pressed against the face of the friction disk by the action of a foot-treadle or hand-gear coupled to a lever arm on a screw-threaded sleeve 48 on the stationary bush. When the foot-treadle is released, the sleeve 48 is turned backwards by a spring and the loose pulley is positively disengaged from the friction disk and is stopped by contact with a stationary brakeblock. In the construction shown in Fig. 4, the belt pulley 37 is attached by screws 43 to the boss 35 of a flanged cone 33, which is normally just out of contact with a leather ring 29 sunk in the face of the flanged cone 27 secured on the shaft 22. In addition to being secured on the shaft, the cone 27 rotates on a bearing formed by a bush 21 surrounding but not contacting with the shaft and carried by a bracket 16 adjustably secured to the bench rail 4. This bush also forms the bearing for the boss 35 of the cone 33 and loose pulley. Between the screw-threaded sleeve 48 and the loose pulley is a thrust ball bearing 50 through which the sleeve bears upon the loose pulley to put it into engagement with the rotating friction disk. The loose pulley is withdrawn on the return movement of the sleeve 48 by means of a lip 41. Variation in the speed of each sewing-machine may be arranged for by providing interchangeable loose pulleys and making them readily detachable from the boss 35. A thrust ball bearing 75 is provided at the end of the line of shafting. Each driving- set is lubricated with oil from a cavity 86. A guard or shield secured to the underside of the bench protects the operator from the pulley when rotating and a tubular non-rotating sleeve extends over each length of the shaft between the belt pulleys. A hand-gear for operating the sleeve 48 is shown in Fig. 7. To start the machine, the rod 107 is pulled upwards, the cross-pin 109 upon it passing through a slot 110 which extends across the socket of the rod 107, and is then turned so as to bring the cross-pin 109 out of line with the slot 110, and so cause it to rest upon the table and hold the rod 107 raised.

Granted: 1913-03-13
Abstract: 24,436. Clark, D'A. M., [Bradley Pulverizer Co.]. Oct. 25. Roller-and-ring mills. - In a pendulum mill for grinding slag, ore, rock, &c., the coupling between the driving-shaft and the roll-shaft is constructed so that during rotation of the parts in the forward direction, the tapered upper end of the roll-shaft tends constantly to be drawn into the tapered hole in the crosshead. Instead of a retaining-nut at the upper end of the roll-shaft, a steel pin 58, Fig. 1, is driven through a hole in the tapered part of the shaft, and its projecting ends rest upon diametrically-opposite cam-seats 59, Fig. 2, formed on the top of the cross-head 53. The oppositely-inclined cam-seats are preferably made as helical surfaces, the low portions of which are adjacent abutments 60, and, when assembling the parts, the ends of the pin rest on the cam-seats at their low parts. The crosshead rotates from the high towards the low parts of the cam-seats, so that the ends of the pin tend to travel toward the high parts of the seats and to pull the shaft 56 upwards into the tapered hole 54 in the cross-head. The radial arms 52 of the cross-head carry segments 51 having convex end faces co-operating with concave seats 50 in the hub 28 of the driving- pulley 29 and the attached depending portion 30. The depending-shaft 27, on which the pulley 29 is mounted, is carried in a bearing 22 on the cross-piece 20, and the bearing 19 clamped on to the tubular portion 30 rests in a concave seat formed by an annular member 17 carried by the frames 15. The suspensionmember 57, which sustains the weight of the cross-head, roll-shaft, and roll, is made as a spherical segment and is seated in a concave bearing 33 carried by the portion 30.

Title: Improvements in Wire Stretching Devices or Machines.
Inventor: SCOTT ARCHIBALD DOUGLAS
IPC: B21F9/00
Filed: 1913-02-11
Granted: 1913-11-27
Abstract: 3517. Scott, A. D. Feb. 11. Winding - machines; creel arrangements.- In a machine for winding wire coils, having an attachment for stretching the wire to reduce its diameter to the desired gauge, the wire passes from a spool 3 at a speed regulated by a controlling-member 14 operated by a carriage 10 carrying a pair of pulleys 7. The carriage has a pawl engaging pins 59 on a post 11, and is vertically movable by the pull of the wire. The member 14 is pressed by a spring or weight against a roller 44 on the carriage, and its ends are connected by bell-cranks 40, 41 and a rod 43 to a rock - shaft 42, which is connected through a lever 52 to a spring- controlled brake 45 on the supply spool so as to vary the supply therefrom. If the carriage falls to a very low position, a belt - shifter 60 is operated from the member 14 through levers 62, 64 and rod 61 to rotate the spool in the reverse direction to take up excess of wire, the brake drum having a ratchet connexion with the supply-spool shaft. The wire from the spool passes several times around the pulley 18, over the outermost of the pulleys 6, and several times round the pulley 17, from which it passes round the outer pulley 7, middle pulley 6, inner pulley 7, inner pulley 6, and thence to the winding-mandrel by way of two further pulleys 12, 13 carried by a pair of horizontally swinging frames 5, 5<a> and a guide-wheel, the traverse mechanism of which is similar to that described in Specification 28,330/10. The stretching of the wire is effected between the two pulleys 17, 18, owing to the difference in their diameters. When it is necessary to wind back a portion of the wire, after stretching, on to the feedspool, and then again to wind it on to the mandrel, further stretching of the wire already stretched is prevented by connecting the pulleys together, so that they may move independently and thus at the same linear velocity during the back-winding, and also during the first portion of the succeeding forward winding operation, and then be automatically locked together for stretching the remainder of the wire.
