Title: Improvements in and relating to clothes washing machines
IPC: D06F37/30
Filed: 1946-12-09
Abstract: 619,422. Washing - machines. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 9, 1946, No. 36336. Convention date, Dec. 8, 1945. [Class 138(ii)] [Also in Group XXIV] A machine for washing clothes comprises a driven shaft 2, a driven clutch member 61, axially-yieldable arms 64 connecting the driven clutch member to the driven shaft, spring means 69 opposing axial movement of the driven clutch member, a second clutch member 73, an axially-expansible corrugated bellows 76 connected between the second clutch member and a driving shaft 22, a fluid pump 34 driven by the driving shaft 22 for supplying fluid pressure to the bellows 76, a discharge port 88 for the bellows, a centrifugally-operated valve 89 for closing the port when the speed of the driving shaft reaches a predetermined high value, and means controlling the flow of fluid from the discharge side of the pump to the bellows. The invention is applied to an automatic machine wherein a spin basket mounted on the shaft 2 is disconnected from a driving motor and held stationary while an agitator in the basket is oscillated for washing the clothes, and then connected to the motor and rotated at relatively high speed to extract' water from the clothes. As described, the invention is applied to the machine disclosed in Fig. 18 of Specification 625,324. In this machine, the shaft 1 carrying the agitator is oscillated through mechanism contained in a rotatable twopart frame 15, 21 from a shaft 18 adapted to be coupled to the tubular driving shaft 22 of the driving motor 23 by clutch members 43, 45. In order to rotate the spin basket at high speed, the clutch member 43 is raised from engagement with the clutch member 45, and expansion is effected of the bellows 76 which are connected between the clutch member 45 and the clutch member 73, so that the latter member is lifted into contact with the clutch member 61 which is carried by the frame part 21; the upward movement of the member 73 is caused not only to effect engagement with the clutch member 61, but to lift the latter from a brake 60 on to which it is pressed by the springs 69 when the agitator is oscillating. The lifting of the clutch member 43 and expansion of the bellows are effected by oil discharged from an eccentric pump 34 disposed in the foot of the shaft 22, the discharge being controlled by a plunger 49 operated by an electro-magnet 48. To prevent the build-up of oil pressure in the bellows until the motor reaches a predetermined speed, and to regulate the pressure in the bellows so as to prevent overloading of the motor, the discharge opening 88 in the bellows is controlled by the centrifugal valve 89 which is carried by a pivoted arm 90 and biased to open position by a weight 92; alternatively the valve may be biased to open position by a spring and closed by means of a weight. Specification 625,325 also is referred to.

Abstract: 1388848 Valves GESSEY & SON Ltd 3 Aug 1972 [3 Aug 1971] 36336/71 Heading F2V A mxing valve for hot and cold water comprises a rotary spindle 12, Fig. 2, formed with two cams 24 and 25 for actuating valves 22 in two inlet passages 18, the valves being prevented from rotating by engagement of fluted shanks 28 with the side surfaces of the cams. The flow from the inlets can be shut off when repairing the valve by fluted valve members 30, Fig. 3, in each of the inlet passages. Inward movement of a screw 31 urges these members against a seat 31. When the spindle 12 is rotated, hot water is not admitted to the mixing chamber 13, Fig. 2, until the cold water inlet is fully open. Continued rotation of the spindle progressively increases the proportion of hot water until the hot water inlet is fully open. Further rotation of the spindle gradually closes the cold water inlet so that the water leaving the mixing chamber becomes hotter. After 320 degrees of movement of the spindle the hot water inlet is gradually closed until both inlets are again closed. A knob (not shown) carried by the spindle 12 includes a spring loaded plunger which prevents the valve being turned directly from the fully closed position to the hot position.
