Title: Improvements in or relating to control systems for electrically operated washing machines
IPC: D06F33/36
Filed: 1957-08-01
Abstract: 820,599. Control systems for heating resistors. MASCHINENFABRIK P. PFENNINGSBERG G.m.b.H. Aug. 1, 1957 [Sept. 8, 1956], No. 24433/57. Class 38 (4). In an automatic washing-machine the sequence of the washing operations is arranged to be interrupted until a predetermined water temperature has been reached. The sequence of washing operations is controlled by a preset device comprising two discs 2, 3 driven by a motor 1. The washing process normally begins with the discs 2, 3 having the positions marked A at a registering position. When the washing container is filled with water a float switch 9 is closed so that the motor 1 is energized over contacts 5, 6 to drive the discs 2, 3. Simultaneously, relays 21, 22 are energized over contacts 5<SP>1</SP>, 16 and contact 14 of a temperaturesensitive switch, the relays 21, 22 causing the water heaters and the main washing machine motor to be energized respectively. If, when the disc 3 has rotated through an angle α to position B where the arm carrying the contact 5 enters a recess 4, the water is not sufficiently heated the motor 1 is de-energized due to the contacts 5, 6 opening. The water heaters remain energized since contacts 5<SP>1</SP>, 16 remain closed until, when the water reaches the required temperature, a thermostat 13 in the washing container causes the switch 14 to open to deenergize the water heaters and the main motor and causes a switch 15 to close to re-energize the motor 1 to continue the drive on the discs 2, 3. When the discs have rotated through an angle (α+ #α) the arm bearing the contact 5<SP>1</SP> enters a recess 10 in the disc 2 whereby a circuit is completed for a relay 23 which causes energization of the main motor such that it effects a " centrifuging " operation. If, when the discs have rotated through the angle α, the water has become sufficiently heated the switch 15 will be closed when the contacts 5, 6 opens; the washing sequence will not therefore be interrupted.

Direction indicators of a vehicle are operated by a switch ring 2 which, when rotated, causes one of a pair of return members 6 to move into the path of a driver 14 which rotates with the steering wheel so that return movement of the steering wheel will cause a deriver to engage a return member 6 and thereby cause member 6 to exert pressure on a stop 5 attached to the switch ring 2 to return the switch ring to its neutral position. The surfaces of member 6 and/or of stop 5 are roughened, so that the return mechanism will operate even if the steering wheel is returned rapidly, and the surfaces may be provided with serrations of a depth of 0À1-0À3 mm. The surfaces of a member 6 which co-operate with driver 14 should be at an angle of 70 degrees and may be of stepped form. Each stop member 6 is pivoted on a pin 11 fixed to the lower housing and extending through an elongated slot in the member. A compression spring 9 in the slot urges the member against the pin but allows it to yield if the switch is held in an " on " position whilst the steering wheel is returned. A spring 7 biases each member 6 towards a stop 8 on the lower housing.

Filed: 1930-08-21
Abstract: 365,612. Electric switchgear and snap-action switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and ADAMS, W. S., Bella Vista, Vernon Avenue, Hillmorton Paddox, Rugby. Aug. 21, 1930, No. 25054. [Class 38 (v).] Relates to switches which may be employed for controlling the disconnection of potential transformers in switch gear arrangements which are provided with contact mechanism adapted for producing a quick make and break of the current, such as of the transformer magnetizing current, when the transformer casing is removed. As shown in the Figure, the contact 9 consists of a spring- pressed plunger bearing on the underside of the transformer casing 2. The contact holder 3 is secured to a fixed conductor 4 by a coiled spring 8 and has a transverse slot in which are mounted oppositely spring-pressed plungers 6 extending through slots 7 in a fixed tube 5 to engage internally an insulating tube 10 depending from the transformer casing. This tube is provided with a groove at 12 so that as the casing 2 is lifted the contact holder 3 is raised within the fixed tube so extending the spring 8, but keeping the contact 9 in engagement with the casing 2. When the plungers 6 reach the upper ends of the slots 7 in the tube 5 the plungers 6 are pressed together and escape from the groove 12 so that the lost-motion is taken up and the contact 9 is drawn away quickly from the casing 2 under the action of the extended spring 9. A similar quick-make action occurs during the replacement of the transformer casing, the engagement of the contact 9 being produced by the compressing of the spring 8 when the lower end of the slot 7 forces the plungers 6 past the inclined opening 11 of the insulating tube. In a modification, Fig. 2 (not shown), the holding up of the movement of the contact during separation is produced by the interengagement of a shouldered conical contact head with a spring- armed contact secured to the underside of the transformer casing, the insulating tube in this arrangement being loosely mounted on the lower contact structure.
