GUSTAF E. ANDRE, OF CHICAGO, ILLINOIS.

WRINGER.

Application filed April 2, 1921. Serial No. 457,878.

To all whom it may concern:

Be it known that I, GUSTAF E. ANDRE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in-Wringers, of which the following is a full, clear, concise, and exact description.

My invention relates to clothes wringers and has a number of objects and advantages in view.

In accordance with one characteristic of my invention a drain board is employed which is automatically adjustable by the mechanism of the wringer to slope downwardly and away from either side of the wringer.

In accordance with another characteristic of the invention a wringing roller is associated with a feeding roller structure that is adjustable in any suitable way into co-operative relation with a wringing roller upon either side of the wringer whereby such wringer roller and the feeding roller structure will grip the clothes and force their 7 passage to the wringing rollers from either side of the wringer. There is preferably mechanism governed by the actuating mechanism of the wringer for placing the feeding roller structure into co-operative relation with a wringing roller upon either side of the wringer according to the direetion in which the wringer is turned.

My invention also includes a drain board so interconnected with the feeding roller structure that the adjustment of one is accompanied by the adjustment of the other in order that the drain board will drain downwardly at that side of the wringer at which a feeding roller is co-operatively related with a wringing roller. The structure is such that adjustment of the feeding roller structure and the drain board may be effected manually independently of the roller actuating mechanism and I do not wish therefore to be limited to the employment of this mechanism for that purpose.

In accordance with a further characteristic of the invention one of the wringing rollers and each feeding roller are provided with intermeshing gear wheels or pinions, some of the teeth of one of these wheels being so mutilated that the feeding roller will be automatically moved away from the wringing roller once in each revolution to widen the space between these rollers to ac- "frame sidesl and 2, and

commodate clothing that is too thick to be received between the wringing and feeding rollers through the spacing that normally intervenes between them. \Vhile this characteristic of my invention is embodied in connection with each of the feeding rollers, the invention is not to be limited to the employment of two feeding rollers having such characteristic.

In the preferred embodiment of the invention the two feeding rollers, where such are employed, have a common oscillating mounting which is so connected with the drain board that such board is changed in its inclination each time one feeding roller is substituted for the other in its relation to a wringing roller.

I also desirably provide a guard which overhangs the wringing and feeding rollers to protect the operator who is feeding clothes into the wringer.

I will explain my invention more fully by reference to the accompanying drawings in which Fig. 1 is a side view of a wringer constructed in accordance with the invention on line 1-1 of Fig. 2; Fig. 2 is a view in elevation of the wringer; Fig. 3 is a detail View showing one wringing roller and a portion of the mechanism associated therewith that is operated by such wringing roller to shift the feeding rollersand change the adjustment of the drain board, this figure being taken on line 33 of Fig. 1; Fig. 4 is a perspective view of a part of the structure shown in Fig. 3; Fig. 5 is a view in elevation of a part of the wringer; andi Fig. 6 is a view of one end of the wringer.

Like parts are indicated by similar characters of reference throughout the different figures.

The frame of the wringer may be made in any suitable way, the frame shown including the upright sides 1 and 2, the top rail 3 joined with these sides by bolts 4 and the bottom bolt 5 between the bottom ends of the sides 1 and 2. The wringing rollers 6 and 7 have their shafts 8 and 9 received in suitable bearings that are provided within the spaces 10 formed in the rotat-ably mounting the wringing rollers forms no part of my present invention and may be such as is commonly employed, a description thereof need not be furnished.

In accordance with common practice, the axes of the wringing rollers 6 and 7 are in as the method ofto bring one the same vertical plane. The lower roller 6 is desirably driven by power applied by hand or otherwise to its shaft 8 and driving power is communicated fromthis shaft by means of the gears 11 upon the shaft 8 and the gears 12 upon the shaft 9 that mesh with the gears 11. The usual springs 13 press the top wringing roller 7 toward the lower wringing roller 6 and maintain the gears 12 and 11 in mesh or restore them to meshing engagement after the upper roller has been abnormally moved away-from the lower roller. The usual thumb screws 1 1 may be employed to adjust thepressure that is furnished by the springs 13. The shaft 8 may be turned in one direction or the other according to the direction which the clothes are fed to and are to pass through the wringer. The wringing roller 7 is shown as being associated with two feeding rollers 15 and 16, the feeding roller 15 being brought into co-operative relation with the roller? to feed clothes to the wringing rollers when the clothes are fed to the left when the structure is viewed as itappears in Fig. 1, the feeding roller 16 then being out of co-operative relation with the wringing roller 7. When the clothes are to be fed toward the right the feeding roller 15 is removed from association with the wringing roller and the feeding roller 16 is brought into cooperative relation with said wringing roller to feed clothes to the wringing rollers. Both feeding rollers are desirably supported upon a common oscillating mounting or' framework 17, this frame being mounted to turn upon the shaft 8.- A T-shaped guard 18 has its stem portion supported upon the u giiard overlying the top wringing roller and extending laterally thereof beyond the same so that either feeding roller is covered by the guard when in co-operative relation with the upper wringing roller.

The frame 17 is automatically oscillated by the actuating mechanism of the wringer feeding roller in co-operative relation with the uppermost wringing roller if the shaft 8 is turned in one direction and to bring the other feeding roller into cooperation with preferably the same wringing roller if the rotation of the shaft 8 is reversed. The mechanism by which this result is accomplished is preferably inclusive of an end plate 19 which is loose upon the shaft 8 but is in frictional engagement with one end of the roller 6. This plate is formed with a lug 20 that extends longitudinally of the rollers into an arcuate slot 21 formed in a side of the frame 17, this slot being desirably concentric with the shaft 8. When the rotation of the shaft 8 is reversed the roller 6 will shift the position of the end plate 19 tobring the lug 20 into engagement with a new end of the slot 21 to of my invention the guides per shaft 9, the end of the top of the of the wringer toward force a reversal in the position of the frame 17, Fig. 1 illustrating the lug 20 upon this end plate in transition from one end of said slot to the other. To make the action more positive the plate 19 may also be provided with a lug 22 brought between both wring ing rollers and adapted to be gripped thereby positively to force the oscillation of the frame 17. A bolt 23 is connected at its upper end with the ear 24 at the bottom of the middle portion of a side of the frame 17 In the preferred embodiment of the invention there is preferably one such bolt thus associated at each end of the frame. Each bolt is adapted to slide at its lower end through an oscillating guide 25. A spring 26 is disposed between each guide 25 and the corresponding ear 24, these springs serving to snap the frame 17 and the drain board each into its final position each time the hinged upper ends of the bolts 23 pass the dead center. Said springs 26 also serve as yielding cushions which press the active feeding roller toward the complemental wringing roller and yield to accommodate the varying thicknesses of the clothing being passed through the wrmger.

In accordance with an important feature 25 form integral parts of a drain board structure 27 which is mounted mid-way between its ends upon and between the sides 1 and 2 of the wringer frame, as indicated at 28. Each time the frame 17 1s oscillated from one sideto the other the guides 25 are oscillated in a reverse direction and carry with them the balance of the drain board structure. A leaf spring 29 is mounted beneath the drain board and rides over the bolt 5, this spring being shaped to hold the drain board in either of its adjustments. By the construction illustrated, whenever the feeding roller 15 is in co-operati've relation with the wringing roller 7 the frame slopes to the left (Fig. 1) and the drain board slopes to the right and when the feeding roller 16 is in co-operative relation with the wringing roller 7 the frame 17 slopes to the right and the drain board slopes I to the left. Thus water which is wrung from the clothes is drained back at the same side which the clothes are fed. The wringer actuating mechanism thus serves to interchange the feeding rollers in their relation to the same wringing roller and at the same time to shift the inclination of the drain board but I do not wish to be limited the accomplishment of both of these resu ts.

Each feeding roller has

gears

30 and 31 which mesh with the gears 12 upon the wringing roller 7. The gear wheel or pinion 31 upon each feeding roller has a projection indicated at.32 which, when brought against the teeth of the gears 12 force separation of the active feeding roller from the complemental wringing roller to increase the space between these rollers for the passage of a mass of clothes which is thicker than that adapted tothe normal space between the feeding wringer rolls. The frame pieces 33 serve as guides that are interposed between one wringing roller and the two feeding rollers to confine the clothes to passage between the wringing rollers. As indicated, the feeding roller which is in action is positively driven by means supplied in addition to the wringing rollers whereby the space between the active feeding roller and the wringing roller complemental thereto may be varied while the feeding roller driving means is functioning. The feeding roller driving means desirably resides in meshing gears but is not to be thus limited.

From the foregoing description of my 1nvention it will be observed that I have provided a swinging mounting for the frame that carries the two feeding rollers and mechanism for effecting the oscillating adjustment of this frame and while this adj ustment is preferably automatically effected I do not wish to be limited thereto nor to the accompanying adjustment of the drain board. It is also apparent that I have devised an automatic adjustment of the drain board and while such adjustment is desirably effected concurrently with the ad ustment of the feeding rollers, I do not wish to be limited to such an arrangement. In certain aspects of my invention it is not to be limited to a feeding roller structure employing two feeding rollers either of which is in cooperative relation with the wringing roller while the other is out of such co-operative relation.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my lnvention I claim as new and desire to secure by Letters Patent the following 1.
