Title: Improved clothes washer machine
IPC: H02P25/18
Filed: 1959-06-18
Abstract: 869,219. Control of A.C. motors; speed-responsive switches. GENERAL MOTORS CORPORATION. June 18, 1959 [June 27, 1958], No. 20898/59. Classes 38 (3) and 38 (5). A clothes-washing machine has a two-speed single-phase induction motor 16 which drives an agitator when the motor rotates in one direction, a tub being spun when the motor operates in the opposite direction. Water is supplied to the tub through a thermo-responsive valve and is removed by spinning to a lower chamber from which it is pumped to a drain, Fig. 1 (not shown). When a selector switch 54 is set for low-speed operation and the motor is accelerating, main motor windings 36, 38 are connected in parallel for a normal pole arrangement, and a starting winding 40 is energized. When the motor reaches a predetermined speed, the starting winding is disconnected by a centrifugal switch 56 and the main windings are connected in series for a higher pole arrangement. If a blockage occurs in the tub which tends to decrease the speed of the motor, the original circuit is re-established and the motor accelerates. Adjustment of the switch 54 to a higher speed position connects the main windings 36, 38 in parallel and energizes the starting winding 40. The starting winding is cut out at a predetermined speed, the motor continuing to accelerate until full speed is reached. Thereafter, if the speed of the motor decreases to a low value, the starting winding is re-connected. A change-over switch 60, 61 is provided for reversing the motor. The speed-responsive switch comprises weights 130 and washer 132 which move outwardly against the force of a spring 133 as the motor accelerates. When the washer engages projections 148, arms 146 are forced apart until the washer is beyond the outer side of the projections. When the motor decelerates, the spring 133 forces the washer inwards into engagement with the steep sides of the projections. Due to the configuration of the projections 148, the starting winding is disconnected at a predetermined speed but is not reconnected until the speed has fallen to a lower value. When the motor is at rest, spring 90 holds the base of the cup 81 against the washer 132 so that contacts 116, 76 are engaged. At a low speed, the washer engages cam surface 80 so that contacts 116, 76 are disengaged, the switch member having pivoted about contacts 102, 106. As the washer approaches projections 148, contact 94 engages contact 98 and, at a high speed, the contacts 102, 106 are broken, the switch member pivoting about the contacts 94, 98. The switch member 82 is supported on pins 70, 72, whilst the weights and guide washer are slidably mounted on pin 134 projecting through the motor shaft 136.

[Class 116] A liquid dispensing apparatus'has a rotatable turret in which is mounted the window of a register which continuously faces the direction in which the liquid, such as petrol is to be dispensed. A standard 6 has a cap 8 upon which the turret 9 is mounted to turn about a vertical axis. Petrol is pumped through a tube 24 to a chamber 25a in a casing 25. The lower end 26 of the discharge pipe 27 communicates with the chamber 25a and is mounted in bearings 28 to turn about a vertical axis. Sealing devices are provided to prevent leakage of petrol around the pipe. The petrol passes from the pipe 27 through a meter 32, rotatably supported on the hub of a reel 35, then through the outlet pipe 40, similarly mounted to the pipe 26, into the chamber 37 in the hub. The reel is rotatably supported on a bearing 36 carried by a plate .34 fixed in the base of the turret. The pipe 27 is fixed to the plate 34 as at 33 so that the pipe turns with the turret. A hose 12 is wound on the reel and communicates at its inner end with a passage 51, which leads from the chamber 37. The outer end of the hose passes through horizontal and vertical rollers 52, 53 and is attached to a nozzle 14 which rests in the cavity 15. A spring 54, mounted in the reel rewinds the hose after use. The register 59 is fixed to the meter 32 by brackets 60 and the meter is fixed to the turret by channels 50. When the nozzle is removed from the cavity 15 and the hose pulled out, to service a car, the side thrust exerted on the rollers 53 turns the turret and hence the register in the direction of the car.

Title: Coin-freed meter for electric current, gas, water or the like
IPC: G07F15/06
Filed: 1920-07-12
Abstract: 151,972. Allgemeine Elektricitõts- Ges. Sept. 19, 1914, [Convention date]. No Patent granted (Sealing fee not paid). Electricity, gas, and liquids, supplying by meter.-Relates to coin-freed electricity &c. meters of the kind in which a preliminary fee for rent or the like must be inserted before the apparatus can be used in the ordinary way. According to the invention, initial rotations of the external knob on payment of the rent fee effect the release of a locking-device, after which further insertions of coins and rotations of the knob enable the mechanism to be set for supplying a predetermined quantity of current &c. The application of the invention to an electricity meter is described. A spindle 5, which can be turned through one revolution by means of a knob 4 on insertion of a coin, carries a loose disk 15 connected to a loose cam 37, which is coupled to the spindle by a spring 36. By this means, on turning the spindle 5, the disk 15 turns with it, and a contact-piece on it passes between fixed contacts 16, 17. The disk 15 is maintained in the circuit-closing position only when the cam 37 is prevented from passing a tooth 39 on a pivoted stop 13, which extends in the form of a hook 13a passing over a cylinder 12, part of which is cut away as shown. When the member 12 is in the position shown in Fig. 2, it does not obstruct the hook 13<a>; consequently, the cam 37 can freely pass the tooth 39 by rocking the member 13. The part 12 can only be turned so as to obstruct the hook when a detent 23 has been moved out of locking engagement with a disk 20, which forms, part of a friction-coupling in the gearing between the spindle 5 and the sun-andplanet gear 6, 7, 8. This movement of the detent is effected by a stiffly pivoted lever 28, brought into action by the initial rotations of the spindle 5, and it occurs when the payment of the preliminary fee is completed. The circuit can then be closed through the switch 15, 16, 17, and the apparatus is ready for supplying current on prepayment in the usual way. The circuit is broken again when the part 12 is restored to its original position by reverse movement of the planet-wheel, which is effected by the meter mechanism acting through the wheel 6. The detent 23 is held clear of the disk 20 until the lever 28 is moved back to its original position when the cash-drawer 35 is taken out by an official; or the detent may be again made operative automatically when a certain quantitv of current has been consumed, or by clockwork &c. Coin-counting devices 31, 14 are provided for indicating respectivelv the total number of coins inserted, and the number of coins paid for unconsumed current.
