682,006. Wringers. HOOVER (WASHING MACHINES), Ltd., and SIBBALD, F. R. Nov. 17; 1950. [Nov. 23, 1949] No. 30031/49. Class 138 (ii). [Also,in Group XXXII] In a domestic wringer of the type including a housing K containing a pair of parallel rollers E<SP>1</SP>, E<SP>2</SP> which are urged towards one another by springs, the springs at each end of the rollers are in the form of a pair of leaf springs H, the centre portions of which act on the roller shafts, whilst each end-portion of each is shackled to the adjacent end-portion of the opposed spring by means independent of the housing K. A U-shaped frame C secured to the top edge of the container (a washing machine A) has extensions C<SP>1</SP> which are slotted at C<SP>2</SP>. The rollers E<SP>1</SP>, E<SP>2</SP> have shafts D<SP>1</SP>, D<SP>2</SP> which pass through the respective slots C<SP>2</SP> and are each journalled at each end in a D-shaped bearing block F. The block F is encircled by a U-shaped plate G which is slotted for the reception of the spring leaves (see Group XXXII). The outer ends of the main leaf of each spring are coupled by shackle plates J to the corresponding ends of the spring of the adjacent roller. The housing K comprises a pressed-metal or plastic casing (Fig. 4) which has slots K<SP>3</SP> for the passage of clothes and end-compartments K<SP>4</SP> which accommodate the springs. Part (not shown) of the casing overlies the ends of the shaft D<SP>2</SP> in order to prevent the springs and roller assembly from rising in the slots C<SP>2</SP>. The bearing blocks F are moulded from porous material which is impregnated with lubricant, and each block may have a recess to accommodate a felt pad which is impregnated with oil or grease. Specifications 613,737 and 647,885 are referred to in the Provisional Specification.
