Title: Railway wagon speed control means
IPC: B61J3/08
Filed: 1973-02-28
Abstract: 1462045 Railway systems; propelling vehicles DOWTY MINING EQUIPMENT Ltd 13 Feb 1974 [28 Feb 1973] 10148/73 Heading B7L A railway wagon speed control means for securement to a railway track rail 1 comprises a wagon speed retarder unit 7, as disclosed in detail in Specification 1,328,086 and also described with reference to Fig. 4, which unit when secured to the track is engageable with wagon wheels on the track; a wagon speed booster 15 engageable when secured to the track with wagon wheels on the track; and a wagon speed responder 34, 35 which initiates retarding operation of the retarder 7 in the case of a wagon moving at or above a predetermined speed and initiates a boosting, i.e. acceleration of the wagon if the wagon is moving below the predetermined speed. The lower end of the rod 9 of the retarder unit operates a control valve unit 11 secured to the bottom of a receptacle 5 guiding the retarder unit and formed in a bracket 2 secured to the said track rail 1. The unit 11 is connected to the booster unit 15 by a compressed air pipe 14. A piston-rod 19 of the unit 15 secured to the rail 1 is raisable to engage and accelerate a wagon wheel when compressed air is supplied to a cylinder 17. A source of compressed air is supplied to an inlet 12 on the unit 11 and supply to the cylinder 17 is controlled by a valve 48 operable by the rod 9. The arrangement is such that when a slow moving wagon wheel approaches the speed control means from the right of Fig. 1 it passes over the rod 19, the head of which is at that time below the level of the head of the rail 1, since the cylinder 17 is vented to atmosphere and engages the retarder 7 so that the rod 9 moving with little resistance as described with reference to Fig. 4 will cause an air venting passage 55 to close and the valve 48 to open sufficiently to allow compressed air to pass to the unit 15 and move the rod 19 upwardly and engage the wheel and accelerate it. If however the wagon approaches the speed control means at a high speed the rod 9 moves against a large resistance and receives a large thrust as described with reference to Fig. 4, and moves the valve 48 further to close-off the air inlet 12 so that the rod 19 is not raised and the wheel will be retarded by the unit 7.

Title: Improvements in or relating to clutch-controlling mechanisms
IPC: F16D47/00
Filed: 1941-08-11
Abstract: 551,003. Centrifugal clutches. MORLEY, F.W.W. Aug. 11, 1941, No. 10198. [Class 80 (ii)] Clutches in which centrifugal masses effecting clutch engagement are carried by the driven member have a spring which presses the clutch into engaging position when the driven member is stationary or rotating at a low speed, and centrifugal means carried by the driven member oppose the action of the spring as the speed of the driven member rises. The invention is shown applied to a two-speed gear and to clutch mechanism of the kind described in Specification 551,002, in which a single set of centrifugal masses 18 alternately effect engagement of clutches 12, 17, the driven plates of both clutches being carried by a casing 13. Plungers 24 urged radially inwardly by springs 26 are mounted on the casing 113 and at low speeds, or when the casing 13 is stationary, each bears on a projection 25 on a mass 18 to move the latter into engagement with a presser plate 21 and engage the clutch 12. As the casing 13 increases in speed centrifugal force acting on the plungers overcomes the action of the springs 26 and the plungers 24 move away from the projections 25. In a modification, Fig. 2 (not shown), the spring- pressed plunger is located within each centrifugal mass which is hollow. The plunger carries a roller bearing upon a wedge-shaped abutment on the clutch casing, the apex of the wedge being in the radial plane containing the axes of the centrifugal masses.

Abstract: 881,687. Photoelectric exposure control. LEITZ G.m.b.H., ERNST. March 23, 1960 [March 26, 1959], No. 10268/60. Class 40(3). [Also in Group XX] A light value setting member in a camera is controlled by an electric motor which rotates a shaft 13a, connected by a gear wheel 20 to the setting means, and a light measuring device 22 having a pointer 23, through worm gears. The intensity of the light falling on the device determines which of two contacts 17a, 17b the pointer 23 will abut, thereby closing the circuit of the electric motor, and therefore in which direction the motor will rotate. When switch 15 is momentarily closed, relay 16 closes, and holds closed switch 19 which causes the motor to drive the shaft 13a and device 22 until the pointer 23 is moved away from switch 17a, 17b.

Title: Improvements in regulating means comprising a centrifugal governor and particularly applicable to internal combustion engines
IPC: G05D13/00
Filed: 1952-04-23
Abstract: 715,709. Fluid-pressure servomotor-control systems. DAIMLER-BENZ AKT.-GES. April 23, 1952 [April 23, 1951], No. 10269/52. Class 135 In regulating means particularly applicable to internal combustion engines and comprising a centrifugal governor controlling a slide valve regulating the supply of pressure fluid to a piston and cylinder type of servomotor, the valve and the servomotor are disposed coaxially with the governor and combined therewith to form a structural unit. As applied to the regulation of the fuel injection pump of a Diesel engine, the means comprise a valve timing shaft 11, Fig. 1, supported by the engine casing 10 and driven through a gearwheel 12 from the engine crankshaft, a sleeve 15 rotating with the gearwheel, and a hollow shaft 21 in screw-threaded engagement with the sleeve and formed with a disc 22 having an extension 34 constituting the cylinder of the servomotor, the piston of which is formed by the enlargement 35 of the sleeve. The disc, which is bolted to the gearwheel 26 driving the fuel injection pump, has a hollow extension 27 for the servomotor control valve 28 which is urged to the left to close a fluid supply and exhaust port 37 in the shaft 21 by the loading spring 33 of a centrifugal spaced governor the weights 30 of which are pivotally mounted between the parts 16, Fig. 2, of a cap secured to the gearwheel 12 and carrying arms 31 which press against the ends of the control valve. The cap is secured to the gearwheel, together with the sleeve 15, by bolts 14 passing through arcuate flanges 17, 18 on the cap parts and a flange 19 on the sleeve. Relative movement between the sleeve and the hollow shaft 21 is limited to the spaces x<SP>1</SP>, x<SP>2</SP> between the flanges 17, 18 and the arcuate flanges 22', 22" by which the shaft is bolted to the gearwheel 26. In the event of a rise in speed, the weights 30 fly out and the arms thereon move the control valve to the right thus uncovering the port 37 in the shaft 21 and allowing pressure fluid, e.g. oil, to pass from the bore in the shaft which communicates with an oil supply pipe 42 into the servomotor space 36. The pressure fluid forces the disc 22 to the right against the pressure of two springs 43 disposed around cylinders 44 covering ports 45 in the disc and the shaft 21 is thus rotated relatively to the sleeve 15 and advances the setting of the gearwheel 26 relatively to the valve timing shaft 11. When the speed falls, the control valve moves to the left under the pressure of the governor spring thus permitting oil in the space 36 to flow into the space 40 and thence to exhaust.

Filed: 1943-06-25
Abstract: 565,166. Cams. MAUDE, J. H. June 25, 1943, No. 10317. [Class 80 (iii)] [Also in Group XXIX] In a hydraulic press, the speed of descent of the ram 13 is checked at an appropriate moment during the working stroke by throttling the discharge fluid from the lower end of the cylinder by movement of a valve 72 operated in a special manner by a cam 89. The cam 89 which may be driven by a rack 69 fixed to the platen 5 of the press, moves from the position shown in a counterclockwise direction, allowing links 87 carrying a roller 88 to assume a vertical position. Later as the wider portion of the cam engages the roller, the links 87 and the lever 83 to which they are pivoted, move bodily upwards and through a link 82 operate the valve 72 into its throttling position. Still later another cam 63 on the same shaft operates a lever 60 to cause the tripping of a toggle 39, 40, which actuates a valve 12 to cause the reverse movement of the ram 13; and a projection 96 on the cam 63 engages the tip 97 of the links 87 so as to return them into their original position. The cams 63, 89 are adjustably mounted on the same shaft and clamped in desired positions relative to the shaft by means of two nuts and two clamping plates which are keyed respectively to the shaft and to a hub on the first clamping plate, Fig. 8 (not shown).

Abstract: 610,456. Change-speed gears. TRACTORS (LONDON), Ltd., and MINES, F. R. April 5, 1946, No. 10637. [Class 80 (ii)] In a change-speed gear a driving shaft 10 is arranged to drive a planet carrier 11 through a centrifugal clutch 12, and compound planetwheels 14, 18 mounted on the carrier mesh with a sun-wheel 15 on a sleeve 16 attached to a driven sprocket-wheel 17, and a sun-wheel 19 respectively. A flange member 20 keyed to the sun-wheel 19 has clamped thereon one end of a helical spring 24, the other end of which is secured to the inside of a brake-drum 27. The helical spring is arranged normally to lightly embrace a cylindrical surface 25 of the planet carrier 11. Studs 31 on the brake-drum 27 engage slots in the flange member 20 and also engage cam faces on centrifugal masses 29 pivoted at 28 on the member 20. The brakedrum 27 is encircled by a brake-band not shown. Anti-clockwise rotation of the driving shaft (looking in the direction of arrows 2, 2) produces anti-clockwise rotation of the planet carrier and member 20, the brake-drum being free. The centrifugal masses 30 acting on the studs 31, cause the brake-drum to move anticlockwise with respect to the member 20, causing the spring to contract on to the cylindrical surface 25, thus establishing a locked forward drive. Application of the brake-band to the brake-drum causes the spring to expand and engage the internal surface of the brakedrum. Thus, sun-wheel 19 is brought to rest and a reverse drive effected.
