Patent GB-132349-A (GB)
IPC: F16H61/02
Abstract: 132,349. Wolseley Motors, Ltd., and Reeve, E. Sept. 11, 1918. Variable-speed epicyclic gearing controlled by electromagnetic brakes and clutches as described in Specification 110,020, comprises an extra clutch for direct driving, with a view to saving current. The top or fifth speed is a solid drive obtained by energizing clutches D, E, Fig. 1, carried by the driving-shaft A'. When this has been done, an extra clutch sleeve M on the shaft A' can be slid into engagement with a member M<2> on the driven shaft A. Current for energizing the clutch and brake coils of the speed gear is supplied from a battery S and distributed by a switch P having contacts r‹r" arranged in pairs. All of these circuits comprise an insulated contact N<3> and an earthed contact N<2>. Normally, a hand-lever N<1> whieh operates the sleeve M bridges the space between the contacts N<2>, N<3>, completing the circuits selected. When the solid drive has been brought into use, movement of the lever N<1> to throw in the extra clutch breaks the circuits and stops all current. In a modification, a lever N for operating the extra clutch is actuated by electric means employing a comparatively small current. A solenoid R carried by the lever N is attracted by solenoids R<1>, R<2> to engage and to disengage the clutch M, M<2> respectively. The solenoids R<1>, R<2> are connected respectively to extra contacts r<14>, r<12> on the switch P. The lever P<1> of the switch P has to be moved clear of the contacts r‹ - - r<11> before it can reach the contact r<14> to throw the extra clutch in. The gearing is suitable for motor-vehicles.

Title: An improved prepayment meter for electricity, gas, and the like
IPC: G07F15/02
Filed: 1936-05-11
Abstract: 464,170. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES. May 11, 1936, No. 13243. Convention date, May 21, 1935. [Class 27] Coin action, mechanicalconnection With delivery proportionate to value of coin.- Clockwise rotation of the setting handle 7 of a prepayment meter tensions a spring 16 through ratchet and pawl mechanism 12 and 13, a gear 18, adapted to be driven by the spring 16 to set the quantity mechanism and close the supply switch, being initially locked by engagement of pawl 20 with one of a pair of diametral notches 19 in the gear 18. Towards the end of the stroke of the handle, an extension of an arm 10 carrying the pawl 12 trips the pawl 20 to release the gear 18 which is rotated by the spring 16 under the control of a magnetic brake 25. Immediately before the release of the gear 18, the inserted coin is discharged from a pocket in an upper drum 5, which has been inverted by rotation of the handle, into a lower drum 4 in which works a coin gauging element 29 on a shaft 27. A pinion 26 on this shaft meshes with the gear 18, so that, as the spring 16 unwinds, the shaft is rotated, and a cam 39 secured to the shaft releases a spring actuated lever 40 which operates through a bell-crank 42 to thrust the shaft 27 axially into the drum 4 to gauge the coin. According to the diameter of the coin, the appropriate one of a set of pinions 32, 33 and 34 carried by the shaft 27 and having different numbers of teeth, is brought into mesh with a toothed wheel 53 which is then rotated by an amount proportionate to the value of the coin, this rotation being transmitted to the quantity mechanism. A cam 37 on the shaft 27 simultaneously moves a lever 47 to close a supply contact 49, which is retained in closed position by a latch 52 controlled by the quantity mechanism. If the coin inserted is not of a correct diameter, an arm 35 turning with the pinions 32, 33 and 34 abuts against a fixed gauging comb 36, which prevents rotation of the pinions and setting of the quantity mechanism ; slipping connection 30 between the shaft 27 and pinions, however, enables the shaft and drum 4 to be rotated to discharge the coin. The handle 7 and drum 3 are returned to their initial position by a spring 11, but the ratchet wheel 13 is held in its set position by a pawl 14. In the modified construction shown in Fig. 2, a pawl 55<1> carried on a fixed pivot is released into locking engagement with the gear 18, by the withdrawal of the pawl carrying arm 10, at the commencement of the spring 16, and unlocks the gear 18 for the clockwise rotation of the handle 7 to tension the spring 16, and unlocks the gear 18 for rotation by the spring 16 when the handle and arm 10 have been returned to their initial positions by a spring 11. Fraud, preventing.-The upper drum 3 into which the coin first falls from the insertion slot, serves as a coin trap, blocking the insertion slot as it is rotated by the handle 7 to discharge the coin into the lower drum 4.

Fluid-actuated valves.-An anti-vacuum valve particularly applicable for use on locomotives and steam engines to admit steam to break the vacuum in the engine cylinders when the engine is drifting is arranged so that the steam acts on a small area to open the valve and on a larger area for closing the valve. In the form shown in Fig. 3 the main actuating piston 3 is formed with an extension of reduced diameter 9 working in a bore 8 which extension is further reduced to form a valve member 11 and to leave a shoulder 12 subject to steam pressure admitted through a pipe 14. The main piston is adjustably loaded by weights 17 mounted on a central spindle 18 and is subject to the pressure existing in the engine valve chests transmitted through a pipe 16. When a vacuum is formed in the engine cylinders the pressure on the piston 3 is reduced permitting the valve 11 to be opened by steam pressure acting on the shoulder 12 to allow steam to pass through the port 11 either directly to the steam chest or indirectly through the steam range and superheater. The device may be mounted on the header of the superheater and may have a permanent leak at 20 to allow a small amount of steam to flow continuously through the superheater.

IPC: G01C19/38
Filed: 1929-05-02
Abstract: 331,972. Berglund, G. H. F. May 2, 1929. Gyroscopic compasses.-Two gyroscopes having their axes inclined at substantially equal but opposite angles to the vertical are mounted independently in gimbal rings within a frame which is rotatable about a vertical axis, the frame being rotated by a servo-motor which becomes operative when the plane containing the axes of rotation of the gyroscopes does not coincide with the plane of the frame, so that the said planes are caused to coincide with each other and with the meridian plane. The receptacle 1 mounted in gimbal rings on the ship, &c. carries the frame 2 which is rotatable about a vertical pivot 3. The gyroscopes 10, 11 are pendulously mounted on horizontal pivots 12, 13 and 14, 15 respectively in horizontal gimbal rings 4, 5 supported on horizontal pivots 6, 7 and 8, 9 in the frame 2. Movement of the gyroscopes relatively to the frame about the pivots 6, 7 and 8, 9 brings into operation a contact device 26 which causes a motor 24 to rotate in one direction or the other and, through the gearing 25, to rotate the frame about the axis 3 until its plane coincides with that containing the axes of rotation of the gyroscopes. The contact device 26 comprises a magnet 126, Fig. 6, carried by an arm 4<1> attached to the ring 4 and acting on a pivoted contact member 127 mounted within an hermetically-sealed box 128 and extending between stationary contacts 129, 130, the box 128 being carried by an arm 5<1> attached to the ring 5. The compass-card 58 is carried by the frame 2. The receptacle 1 contains oil, &c. to support the weight of the gyroscopes, and is stabilized by a gyroscope 37. In order to apply the required torques to this gyroscope to maintain the frame 2 in a vertical plane there is provided between the gyroscopes 10, 11 a T- shaped member 29 capable of turning about its longitudinal axis in a support 30 which can turn about an axis 31 with respect to the frame. The ends of the cross part of the member 29 extend into grooves in members 33, 34 extending from the gyroscopes 10, 11 respectively so that the length of the member 29 lies along a horizontal line bisecting the angle between the axes of the gyroscopes. The extremity of the member 29. carries a contact device 36 of the kind shown in Fig. 6 co-operating with a movable contact on the frame 2. A similar contact means 35 is provided between the frame and the horizontal axis 14, 15. These contact devices control motors 38, 39 the rotation of which is arranged to displace masses 40, 41 to apply .the righting-torques to the gyroscope 37. To reduce friction in the cardan suspension of the receptacle 1 the pivot pins 60, 61, 63, 64 are arranged to be continuously rotated the directions of rotation of the pins 60, 63 being opposite to those of the pins 61, 64 respectively. The current for rotating the gyroscope and for operating the motors &c. is introduced through a distributor 19. Specification 331,956 is referred to.
