    • 814,037. Wringers. WHITE SEWING MACHINE CORPORATION. Jan. 7, 1957, No. 556/57. Class 138 (2). A wringer 10 is foldable down into a washing-machine tub about a pin 26 (see Fig. 2) only when the pin 42 of the pivoted latch member 41 coincides with the radial slot 49 in the annular trough 47 on the underside of the flange 44 (Fig. 3) of the depending tube 43 carried by the wringer. The wringer with its stub shaft 11 and tube 43 are rotatable about the vertical drive 45 into a plurality of indexed positions, the pin 42 moving in trough 47 and preventing folding; while the several positions are determined or indexed by the second latch device 54 with pin 57 spring-urged through a hole 53 in tube 43 and any one of the series of holes 52 in the tubular extension support 28. The: wringer is removable from the support 28 by lifting, but only when the pin 57 is disengaged from holes 52 by depressing the latch 54. U.S.A. Specification 2,679,151 is referred to.
