1 Claim. (01. 68244) This invention relates to an improvement in wringers for washing machines and more particularly to a supporting structure for a wringer, being a division of my copending application Ser.

No. 97,429, filed August 22, 1936.

The preferred embodiment of the invention discloses a wringer and wringer support adaptable for use with a washing machine. The wringer support is mounted for swivel movement on a housing, which encloses reverse gearing adapted to be coupled with the drive shaft of the wringer.

More particularly, the invention is directed to and has for its objects the provision of a wringer and wringer support of extremely simple design which makes possible economical production. The supporting structure is preferably an integral extension of the housing in which the reverse gear mechanism is located and, by reason 20 of the location of the mechanism, and the drive shaft of the wringer, a drive coupling for the wringer is effected simultaneously with mounting the wringer on its supporting housing. The engageable portions of the housing and wringer 25 are designed to interfit, thus enabling the blending of contours and considerable enhancement of appearance. Furthermore, the means by which the wringer is secured in interfitting relationship with the supporting housing is en- 30 tirely concealed and thus objectionable fastening projections are eliminated.

Other and further objects of the invention will be more fully understood from a consideration of the following specification which is taken 35 in conjunction with the accompanying drawings and in which Fig. 1 is a fragmentary side elevation of a wringer and wringer support;

Fig. 2 is a greatly enlarged view of the struc- 40 ture of Figure 1, parts being broken away to show the means by which the wringer is mounted on and secured to the supporting structure of the drive housing;

Fig. 3 is a view of the end of the wringer which 45 is attachable to the supporting housing;

Fig. 4 is an end view of the housing which supports the wringer; and

Fig. 5 is a view somewhat similar to Figure 2 showing the wringer about to be mounted on 50 the drive housing.

Referring now to the drawings and more particularly to Figures 1 and 2, a wringer support is shown, being generally indicated by the reference numeral ID. Attached to this support in 55 a manner hereinafter more fully set forth is a wringer H. The wringer II, for descriptive purposes, may be said to comprise end posts l2, upper enclosing plates 13, rolls l4, and clothes guides E5. The clothes guides l5 are curved at their ends and formed with upwardly inclined 6 side walls l6. The walls l6 overlie the posts H and form therewith a somewhat irregular contour at each end of the wringer. The post I2 is formed with a flat outer face and adjacent the lower end thereof provided with an opening 10 through which a wringer drive shaft l6 projects. Located on the outer face of the post I2 is a plate 49. This plate is provided with an opening through which the shaft [8 projects and is secured to the post in any suitable manner as by welding. The lower end of the plate is formed with an outwardly directed horizontal flange 2|. At the upper end the plate is curved outwardly in a flange 22 which, together with the adjacent portion of the post, forms an upwardly opening pocket 23. Flange 22 is adapted to sustain a considerable portion of the wringer weight and it may, therefore, be strengthened by provision of ribs 25.

The wringer support l0 takes the form of a 25 housing 26 and encloses a reversing gear mechanism adapted to drive the wringer rolls 14 in either direction through connection with shaft IS. The housing 26 is formed with a downwardly directed collar 21 which is swivelable upon a 30 suitable drive housing rigidly supported adjacent the side of a washing machine tub (not shown). The housing 26 extends laterally in the direction of its open side beyond the collar 2'l, being formed without a base wall and having a generally rectangulanrecess or slot 29 in the top wall 30. The slot 29 is substantially the width of the post 12 and is adapted to receive the post therein to a point such that the wall 3|], on either side of the slot 29, abuts the inclined walls [6 of the clothes guide [5. The ends of the side walls 31 are shaped to conform to the contour of the clothes guide I5 and inclined walls l6 thereof. When the wringer is properly positioned with respect to the housing, the walls of said housing blend with the end walls of the wringer and appear unbroken, thus giving the entire structure a unital appearance. Directly beneath the upper wall 30 of the housing and adjacent the base of the slot 29 is located a bar 33. The ends of this bar extend into the side Walls 3! of the housing, being suitably secured thereto. Adjacent the lower edges of the side walls 3| are inwardly directed horizontal flanges or lugs 34. These lugs may be formed integral with the housing or secured thereto, as found most convenient, and are provided with drilled and tapped openings 35.

The reverse gear mechanism which is located in the housing 26 is enclosed at the open end thereof by a plate 31. A drive shaft 38 of this mechanism projects through the plate 31 into that portion of the housing engageable with an end of the wringer. The shaft 38 is hollow and is formed with diametrically opposite openended slots 39. The diameter of the opening in the shaft is slightly greater than the diameter of the wringer shaft 8 for a purpose hereinafter set forth. The ends of the pin 40 of the wringer shaft are adaptedto project into slots 39 and constitute the driving connection between the reverse gear mechanism and the wringer.

When it is desired to mount the wringer on the housing 26, the reversing handle 4| on top of the housing may be turned to the position shown in Figure of the drawings, or at right angles to that shown in Figures 1 and 2. The wringer is first moved to a position such that the flange 22 of plate I9 is located beneath bar 33. The wringer is raised slightly to locate the bar in pocket 23. This portion of the assembly takes place with the wringer at an incline substantially as shown in Figure 5. With the wringer in this position and the flange 22 engaged with bar 33, it is possible to project shaft l8 into hollow shaft 38. Inasmuch as the opening in the shaft 38 is of slightly greater diameter than that of shaft I8, these members may be started in their interfitting assembly at substantially the angle shown in the drawings. The wringer may now be swung into horizontal position, the ends of pin 40 projecting into slots 39. As this movement takes place, the

horizontal flange 2| will move into position directly beneath lugs 34. Suitable openings 42 in the plate 2| permit inserting screws 43 which engage the threads of the openings 35 in the lugs 34.

It will be noted that the lugs 34 and flange 2|, as well as flange 22 and bar 33, are within the housing 26 and entirely concealed from view. Furthermore, the side and top walls of the housing 26 are without flanges or sharp projections and blend with the contour of the end of the wringer. Thus, all projections which might snag and tear clothes being run through the wringer, or injure the hands of the operator, are eliminated, and at the same time, the combined wringer and support presents an attractive appearance.

Although applicant has shown and described only one modification of his invention, it will be apparent to those skilled in the art that modifications or adaptations of the structure may be made without departing from the spirit and scope of the invention as set forth in the hereunto annexed claim.

Having thus set forth my invention what I claim as new and for which I desire protection by Letters Patent is:

A mounting for a wringer comprising a housing having a reverse gear mechanism therein, the top wall of said housing being slotted to receive an end post of said wringer, the side walls of said housing conforming to the outline of the clothes guide of said wringer, a plate on the end post of said wringer, a flange on said plate, lugs in'said housing, said lugs overlying said flange and adapted to have screw engagement therewith, when said wringer is mounted on said housing.
