When how- 1 at each end and at rounded portions 23 has ever, control handles 22 are moved to horizontal positions member 33 moves idler gears 35 and 36 to such position as will contact either the upper roll gear 31 or the lower roll gear 32 to revolve the rolls in either one or the -other direction depending upon which horizontal position of the control handles 22 is selected.

Mounted on square portions of control shaft 21 are eccentrics 44. A drain pan below the wringcr frame is hinged on lugs 46. Studs 47in the drain pan are connected to eccentrics 44 by links 48. Eccentrics 44 are so placed on control shaft 21 that .when control handles 22 are brought to eitherhorizontal position the pan will-slope in one or the other direction as required.

" From the foregoing description it is apparent that when a control handle of my improved wringer is brought to a vertical position the rolls are spread widely apart and are freed from the source of power and from each other so that either may be freely turned by hand in its bearings and the adjustment v of the roll tensions is undisturbed; when the control handle is brought to a horizontal po-. sition toward the operator the rolls are brought together under normal tension, are connected to the source of power and made to revolve to wring clothes away from the operator and the drain pan is slanted to return the water wrung from the clothes toward the rolls may to wring,

the operator and this action may be had by the operator from either side of the wringer, an as there is a control handle at each end of the wringcr it may be conveniently controlled by either the right or left hand as desired, and when my wringcr is mounted on a column to swing thereabout in a horizontal plane to several positions as is common practice it will be found that one or the other control handle is always within easy reach of the operator 'in any of the several positions.

The advantages of my improved construction over common practice are obvious. In a power wringcr as ordinarily made there is a single control handle by means of which direction. The operator of such a wringcr must always remember to manually slant his drainpan in a proper direction when starting If as-frequently happens in ordinary practice an article of clothing being wrung out inadvertently wraps around one of the rolls or anything else occurs to choke the rolls and overcome the source of power the operator may reverse the wring'er if the source of power is suflicient to reverse the rolls against the choking action. This fail-. ing he may strike a catch. usually provided on most such wringers which release the tension screw and breaks the rolls apart. But breaking the rolls apart still does not disconnect such a wringcr from the source of power and the operator must then still reach the. control handle and stop or reverse the d filed June 14th,

be stopped or rotated in either rolls, after which he must reset his catch and readjust the tension of the rolls.

In order to more clearly show my improved wringcr compared with ordinary wringers I show in Fig. 7 a standard two compartment laundry tray and a washing machine 56 of the swinging wringer type equipped with my improved wringcr.

It is common practice to so place the washing machine with reference to the laundry tray thatthe wringcr may be swung to either of the four positions shown which I broadly designate as positions 48, 49, 50, and 51. The operator stands in position 52 when the wringcr is in position 48 or 51. He stands in position 53 when the wringer is in position 49. He stands in position 54 when the wringcr is in position 50. Ease of access to the control handles 22 is hereby obvious. However, when the operator of an ordinary wringcr is standing in position 54 with the wringcr in position 50 and necessity for quickly reversing the rolls occurs he may find that the reversing handle is too far away to be reached from his position as it is on many machines so placed as to then be in a position as at 57 several feet removed from his standing position.

While I prefer that my improved wringcr which I have herein shown and described be driven by a powerunit such as I show in my co-pending application Serial No. 285,369,

1928 it may be used in conjunction with any driving means desired and while I have referred to a number of changes which may be made in the details of the wringcr it isunderstood that other changes in the structure may be made insofar as they are not limited by the prior art and do not depart from the spirit of the invention the scope of which I aim to cover in the following wherein claim- 1. In a wringer frame, two roll shafts rotatably supported for a power washer, a

in bearings carried by saidframe, a gear on I each said roll shaft, a unidirectional power shaft, a gear on said power shaft, two idler gears and manual means carrying the two said idler gears, adapted to be shifted to three positions, the one position to insert one idler gear into mesh between the power shaft gear and the one roll gear, another position to insert the other idler gear into mesh between the power shaft gear and the other the third position to withdraw roll gear, and

from mesh with the roll both idler gears gears. 1
