摘要： 891,003. Fluid-pressure servomotor-control systems; hydraulic transmission of power. BRITISH-JEFFREY DIAMOND Ltd. Feb. 26, 1960 [March 18, 1959], No. 9394/59. Classes 69 (2) and 135. The haulage unit of a coal-cutting machine is driven by an hydraulic motor 90, Fig. 7, of fixed eccentricity, that is supplied with fluid by a reversible variable-displacement radial-cylinder pump 73 driven by an electric motor 85 ; the pump displacement is varied by a sliding block 1 housing a fixed piston 12, a fixed piston valve 16, spring-centred fluid-actuated valves 8, 9, and a manually-adjustable speed-control valve 3. Fluid is supplied to one or other inlet ports 26, 27 from pumps 19, 20, respectively, under the control of a solenoid valve 21. The pumps 19, 20 may be replaced by one unit having two main pistons of different diameter. With the valve 21 in the position shown, pump 20 is connected to exhaust and pump 19 to inlet 26; upon displacing the valve 3, say to the right, fluid from the inlet 26 displaces valve 8 leftwardly and then acts on the right of piston 12, concomitantly the valve 8 opens the left side of piston 12 to exhaust via ports 30, 31 so that the block 1 moves to the right until ports 28, 31 are closed by lands 4, 5 on valve 3. The valve 8 remains in its displaced position. If the valve 21 is now actuated to connect pump 20 to inlet 27 and pump 19 to exhaust then fluid flows through a port 32, opened when the block 1 moved rightwardly relative to the valve 16, and urges valve 9 rightwardly to admit fluid to the left of piston 12, and since valve 8 is still displaced to the left this fluid traverses ports 30, 31 until it is stopped by land 5 of valve 3 whereupon block 1 is forced to the left and fluid from the right of pistons 12 is exhausted through a port 33 controlled by valve 16; ports 28, 31 are then opened to exhaust enabling the valve 8 to centralize and close port 30 and the block continues its leftward motion until ports 32, 33 are closed by lands 18, 17 of valve 16 and the block 1 is stopped in its original position. Manual switching and speed control is effected by an arm 34, Fig. 2, which is connected by gears 38, 39, 40, 42, a double-jawed clutch 45 and bevel gears 47, 48, 49 to a shaft 44 by which the control switch for the electric motor 85, Fig. 7, is actuated; bevel gear 47, 48, Fig. 2, can be selectively engaged with bevel gear 49 by axial manipulation of a rod 50 to determine the direction of rotation of the electric motor. The speed control valve 3, Fig. 7, is operated through a linkage 71 moved by a knob 67, Fig. 2, through a nut 68 threaded on a shaft 58 connected to the knob 67, and interlocking gears and clutch are provided so that shaft 58 cannot be rotated until the arm 34 in in the " on " position; if the arm 34 is moved to the " off " position whilst the valve 3 is set to a given speed the valve is automatically returned to neutral. In the fluid circuit 89, Fig. 7, between the pump 73 and haulage motor 90 is a by-pass valve 92 which is normally held closed against a spring 94 by fluid pressure from a pump 99 passing through a manual valve 101. To stop the motor 90 the spindle 102 of valve 101 is moved to left, whereby the spring 94 is enabled to open by by-pass valve 92 and fluid in the casing of valve 101 is directed to pistons 108 which operate to centralize a rack 109 in engagement with a gear 110a, Fig. 2, on the shaft 58 and thereby set the valve 3 in the " neutral " position. The electromagnet 25 of valve 21 may be connected in series with the motor 85 so that upon a given load current being exceeded the valve 21 will return the pump 73 to zero eccentricity and stop the motor 90; since this reduces the load current the valve 21 will then be returned to its normal position and the pump 73 to its previous speed setting.

摘要： 770,422. Mineral-mining machines. BRITISH JEFFREY-DIAMOND, Ltd., and SAVILLE, A. Y. April 15, 1955 [July 6, 1954], No. 19800/54. Class 68 (1). In a mineral-mining machine cutting head of the kind comprising upper and lower cutter jibs 1, 2 and an intermediate cutter extending between the outer end of the jibs, the intermediate cutter has a vertically extending, serrated cutter 3, 5 secured to a cylinder 8 resiliently attached by leaf springs 9 to a structure 12, such as is described in Specification 770,423, which is referred to, that can slew the jibs 1, 2 and the intermediate cutter about a vertical axis as a unit. The cylinder has an internal partition 17 on opposed sides of which are disposed plungers 15, 16 that extend outwards through the ends of the cylinder to engage blocks 36, 24, slidably mounted in apertures of complementary section extending through the jibs 1, 2. On the supply of pressurized liquid to the chamber on one side of the partition in the cylinder and exhaust of liquid from the chamber on the other side of the partition the ram subjected to the pressurized fluid moves outwards of the cylinder until the associated block engages the roof or floor whereupon the cylinder moves in the opposite direction. After a certain travel of the cylinder it contacts and actuates a spring- loaded mechanism that reverses a two-way valve 19 controlling the passage of liquid to and from the cylinder and the cylinder movement is reversed. Thus the cutter 3, 5 is reciprocated. The valve and actuating mechanism therefore are protected by vertical, mutually-inclined shields that can act as ploughing and loading structures.

摘要： 519,955. Coal-cutting machines. BRITISH JEFFREY-DIAMOND, Ltd., and SAVILLE, A. Y. Oct. 24, 1928, No. 30711, [Class 68 (i)] Means for moving cuttings away from the cutter chain of a coal-cutting machine comprises a plurality of blades or the like rotatable about a common axis and means whereby, during each revolution, the effective area of each blade is varied between approximately zero and a given maximum, the maximum effective area being attained when the blade is nearest the cutter chain. A unit 10 is detachably secured to the machine frame by bolts 12 and includes a worm 21 with a jaw clutch member 15 adapted to engage a spring-pressed clutch member 16 splined to a bevel 17 driven by the crownwheel of the machine. The worm 21, through worm wheel 22, drives a cowl 26 with slotted trunnions 32 in its wall; blades 31 are independently mounted on a shaft 30 offset from the axis of the cowl, each blade passing through one of the trunnions whereby the blades are rotated by the cowl and during rotation reciprocate relatively to the trunnions. A side guard 34 is removably fixed to one side of the unit by hook 35 and pin 36 to prevent return of cuttings a guide chute 38 is similarly fixed to the other side. Apertures 39 in the base plate allow escape of dust.

摘要： 518,547. Coal-cutting machines. BRITISH JEFFREY-DIAMOND, Ltd., and SAVILLE, A. Y. Aug. 26, 1938, No. 25137. [Class 68 (i)] [Also in Group XXIV] In pawl-and-ratchet mechanism adapted for incorporation in the haulage end of a coal-cutting machine, a roller is associated with the pawl to which a fixed stroke is imparted and an adjustable cam plate is provided to be set to co-operate with the roller on the back stroke of the pawl to lift the latter, out of engagement with the teeth. A pawl 10 is pivoted at 11 between a pair of plates 12 journalled on the shaft of the ratchet wheel 13, the plates being oscillated by an eccentric 15 through a connecting-rod 14. On the pawl 10, adjacent the operative end, is mounted a pin 16 carrying a hardened steel roller 17. The pawl is normally urged into engagement with the teeth by a spring 18, but means are provided to mask part of the stroke of the pawl. This comprises an annular cam plate 19 having a bayonet-type connection with a boss 20 on the machine frame and so disposed that the roller 17, will contact therewith on the back-stroke and lift the pawl from the teeth. The cam plate is adjusted by a toothed sector 21 thereon being engaged by a rack 22 which is connected to a threaded member 23 actuated by a coarsepitched thread-24 on a rod 25 actuated by a handwheel 28.
