Abstract: 648,969. Washing-machines. FAVARO, B. Sept. 12, 1947, No. 25091. Convention date, Sept. 20, 1946. [Class 138 (ii)] Relates to a clothes washing machine comprising a tub having a lower water heating compartment communicating with the upper portion of the tub through an aperture in which is fitted either a rotary member for beating the clothes or a stationary member with a vertical duct for delivering water for boiling the clothes. The washing machine comprises a casing 1 mounted on casters 2, in the upper portion of which is housed a wash-tub 3 having an aperture in its bottom communicating with a compartment 6 in which water is heated by electric elements 8 fitted in radial sockets 7. The clothes are beaten by an oscillating member, comprising a bottom 42 raised at its centre and with radial wings 43 around a sleeve 44, which member is mounted over the aperture in the bottom of the wash-tub on a vertically-extending tube 38 fixed to the bottom of the compartment 6. The beater member is oscillated by an electric motor 14 through gears 15, 16, worm 17, a worm wheel 18 integral with an eccentric 20, a rod 21 hinged to a rack 22 slidable in a block 23 supported on tranverse rods 26, and a pinion 40 cut in the lower end of a vertical spindle 39 passing through the tube 38 and which spindle is connected by a square portion 41 at its upper end, to the beater member. The 'worm wheel 18 also drives a vertical spindle 19 to operate a wringer pivotally mounted above the wash-tub. The spindle 19 drives a bevel pinion 33 which may be engaged with either a bevel pinion 31 or a bevel pinion 32 according as to which direction it is desired to rotate a wringer roller 30, by turning a handle 34. The handle may also be manipulated to operate a catch 36 controlling a locking device 37 to position the wringer head. When the wringer is in operation the beater member drive may be disconnected. The rack 22 is disengaged from the pinion 40 by sliding the block 23 along the rods 26 by means of a rod 52, Fig. 6. The rod 52 is connected by a pin 57 to a tail rod 52<SP>1</SP> and is also connected at 58 for longitudinal play with a sleeve 55, surrounding the tail rod and connected to the block 23. Movement of the block by the rod 52 is controlled by a spring-urged plunger 54 co-operating with a notch 59 in the tail rod 52<SP>1</SP> and with a hole 55<SP>1</SP> in the sleeve. When the rod 52 is fully withdrawn the plunger 54 engages a notch 56 in the sleeve. The machine may be used for boiling clothes by removing the beater member from the tube 38 and mounting thereon a stationary member to facilitate the circulation of the water. As shown in Fig. 3, the stationary member comprises a perforated disc 45 with a vertically-extending tube 46 surrounding the tube 38. Water is circulated by passing up the tube 46 and being ejected through nozzles 47 at its upper end. Lugs 49, are also fitted to the upper end of the tube 46, for supporting radially extending rods 50, which serve to hold the clothes down against the disc 45. Fig. 3 also shows a cover 5 for closing the opening 4 of the wash-tub.
