Abstract: 538,424. Washing and wringing machines. McDONALD, J., April 1, 1940, No: 5789. [Class 138 (ii)] A combined washing and wringing machine is constructed with a wash tub E mounted on an intermittently driven turntable d<SP>1</SP> and within which a vertically reciprocating plunger H operates, and a wringer mounted for rotary positioning on a pillar C supported on a gear box A housing the common driving shaft for the washer and wringer and itself supported on a pair of rails B carrying the whole framework. The wash tub has spaced blocks d<SP>2</SP> to centralise it on the turntable d<SP>1</SP> which is driven through a ratchet wheel e from a pawl e' which is oscillated by a link e<SP>6</SP> from a rock shaft d' actuated by an arm d<SP>6</SP> from a vertical bar G supporting the plunger H and itself reciprocated vertically by an eccentric g<SP>5</SP> on a shaft a mounted in the gear box A. The shaft a is driven by a worm and worm wheel from a shaft extending outside the gearbox and carrying a pulley a<SP>6</SP>, Fig. 3, driven by a band f<SP>61</SP> from a pulley a' on a motor F mounted on a pivot f<SP>2</SP> so that it may be rocked by a treadle F<SP>6</SP> to tighten or slacken the band for driving or arresting the drive to the shaft a. The treadle may be held depressed for driving by a roll F<SP>10</SP> on a pivoted hand lever F", and the bar G may be held in raised position to arrest the plunger and turntable by a roll g<SP>6</SP> on a pivoted lever g<SP>7</SP> which can be rocked from a hand lever with means for securing in operative or inoperative position. The plunger H is supported with provision for vertical adjustment by a screwed spindle h in a nut h<SP>1</SP> on an arm h<SP>2</SP> which is mounted on a vertical pivot h<SP>30</SP> to permit of swinging the plunger clear of' the washtub or to permit of retention with the plunger in operative position, by engagement in a notch in a plate h<SP>6</SP> on the bar G. A pivoted couriterweighted arm h<SP>10</SP> with handle piece h<SP>11</SP> normally retains the plunger in position over the tub, the handle h<SP>11</SP> preventing adjustment of the handle h<SP>3</SP> of the screw h in this position. The wringer is supported on a frame j<SP>3</SP>, Figs. 1 and 6, secured to a gear box J mounted by a sleeve bearing i<SP>12</SP> at the upper end of a pillar C supported on the gearbox A, and the pillar houses a vertical shaft I driven by bevel gear i<SP>2</SP>, i from the shaft a through a screw and split clamping nut i<SP>6</SP>, Fig. 5, forming part of a ball bearing. A bevel pinion j<SP>5</SP> is flexibly coupled to the upper end of the shaft I and is mounted in a slidable plate j' which can be moved to gear the pinion j<SP>5</SP> with either of a pair of bevel wheels j' on the spindle of the lower roll of the wringer. The plate j' which can be moved to gear the pinion j<SP>5</SP> by means of a crank and hand lever j<SP>13</SP> extending through the side of the gear box J, or may be operated from the outer end of the wringer by sliding a bar K which acts through a pivoted lever K<SP>4</SP> to operate the handle j<SP>13</SP> and move the pinion to neutral position. Specification 406,814 is referred to.
