Abstract: 592,830. Wringers. WILKINS & MITCHELL, Ltd., and WILKINS, E. W. May 31, 1945, No. 13629. [Class 138 (ii)] Relates to a wringer of the kind used in conjunction with a washing machine and driven by a bevel-wheel 22, Figs. 3 and 4, on the upper end of a vertical shaft 21 journalled below the wheel in a carrier 23 which is movable in guides to rock the shaft and bring the bevel-wheel in and out of mesh with two bevel-wheels 38, 39 fast on the shaft of the bottom wringer roll 16 to select the direction of drive of the roller. According to the invention, the carrier is now provided with a transverse slot 26 to engage a cranked end 27 on a vertical spindle 28 guided in vertical bores in lugs 29, 30 on a housing 17 bolted to the bottom one 13 of two similar sheet metal pressings 12, 13 hinged together at 14 to enclose the wringer. The spindle 28 has a handle 32 for rocking it to bring the bevel-wheel 22 into mesh with the wheels 38, 39 for forward and reverse drive of the bottom roller 16. In the handle 32 is a vertical bore for a spring-pressed plunger 34 which takes into one of three depressions in the housing 17 to position the shaft for neutral or either drive. The gap between the lugs 29, 30 is deep enough to allow the handle 32 to be lifted up to free the lower end of the shaft 28 from position holes in. which it fits in the machine casing, thus enabling the wringer to be placed in a required position. The bevelwheels 38, 39 are rigid on a sleeve 36 having a square axial hole to fit the square end 35 of the roller axis, and journalled in a bearing 37 bolted to the housing 17 with the lower pressing 13 between. At the driving end, the upper roller axial projection 40 is journalled in a bearing 41 sliding vertically in a guide 42 forming part of a partition 42a secured in the top pressing 12. Springs 43 press down the bearing 41, the travel of which is limited by the curled end 45 of a plate 44 to which is attached a bracket 46 housing a spring 47 which bears upon a partition plate 48 placed on the bearing 37. At the opposite end the bearing of the top roller is similar. At that end the axle 49, Fig. 5, of the lower roller works in a bearing 50 housed freely in a non-circular hole in a partition plate 51 in the bottom pressing 13 and kept in position by a screw 52 in a nut 53 on the end wall secured by a locknut 55. The spring 47, Fig. 4, tends to lift the top roller and casing round the hinge 14 from the lower. The two parts 12, 13 of the casing are connected by toggle plates 56, 57, Fig. 5, working on a hinge 58 which in the folded working condition lies outside the line of centres of the other hinges 59, 62 and is held by a bentup end 64 of a quick release bar 66, Fig. 3, on one side of the machine, the release bar 65 on the other having a co-operating hooked extension so that pressure on either bar releases the toggle to allow the spring 47 to open the rollers and casing. A shield 57a is attached to the toggle plate 57 to cover the mechanism. The release bars 65, 66 have bent-down ends and are turned in to pass with free clearance through holes in the lower pressing 13 and are retained by cotter pins 69 at the driving end and at the outer end are retained in normal position by a spring 74, Fig. 5. Water draining from the wringer is deflected to one side or the other of a board 86, Fig. 9, by a trough 76 rigid with a rod 77, a downwardly turned end 78, Fig. 4, of which is engaged and adapted to be rocked by a slot in the carrier 23.
