The object of my invention is to provide a base or main body of a clothes wringer of distinctive and attractive contour which is of such form as to provide spaces therein for thereception of two springs arranged parallel with the roll ares, or springs arranged transversely or" the roll axes, at each end of the structure which springs, by mechanisms of various forms, may be readily associated with and dissociated from one of the rolls, the structure being also so formed as to provide unusually wide clothes aprons.

The accompanying drawings illustrate my invention.

Fig. 1 is a invention;

Fig. 2 an end elevation;

Fig. 3 a front elevation;

Fig. 4 a medial transverse section;

plan of an embodiment of my Fig. 5 a transverse section showing springs arranged longitudinally within the base, and

Fig. 6 a transverse section showing a transverse spring the duplicate of which would be arranged at the other end of the structure.

The details of spring structure and means for actively associating the springs with the rolls form no part of my present invention and are here shown merely to illustrate the' adaptability of my improved base.

In the drawings 10, 10 indicate two end standards having at their bases oppositely extending hollow arms 11, 11 opening at their inner endsinto the lower ends ofthe standards. These arms have an internal width (longitudinally. of the base) and length (transverse of the roll axes) to receive a. transverse spring 12, said spring bridging across the lower end of the intermediate standard 10. The end standards 10 most conveniently have a channel cross section with interned, non-meeting lips at the free ends of channel arms. V

Extending between the inner walls of the hollow arms l1, l1, lengthwise of the base, are the two laterally extending downwardly inclined clothes aprons 13, 13, each of which at its inner edge is supplemented inwardly and downwardly, as indicated at 14, 14, to form a trough for the lower roll 15, The arm 11 rise above the surfaces of the clothes aprons 13 to confineand guide the clothes and the water flow. The two aprons 1314 may be separate sheets separated at their inner edges to permit the direct downward flow ofwater from the lower roll or they may be made from a single sheet of metal with a medial slot and they may be integral with the end standards 10.

The channels 16, 16 beneath the peak formed at the junction of parts 13-1 l open at their opposite ends into the interiors of the end standards 10 so that spring elements 17, 17 (which in the form shown in Fig. 4 are torsion springs) may be nested therein, their ends projecting into the interiors of the lower ends of standards 10 where, by suitable mechanism, they may be coordinated with one of the rolls. The base may be readily, and most conveniently, formed of pressed sheet metal with welded junctions, where necessary, in a manner well understood by sheet metal workers and diemakers, or may be formed bycasting.

In any event, the fundamental characteristics are that the channels 16 open at their ends into the lower interiors of the standards 10 and the laterally extending hollow arms 11 communicate at their inner ends with the lower interiors of the standards 10 and have internal dimensions .suflicient to receive transversely positioned springs.

In Fig. 4 each torsion spring 17 at each end is provided with an inwardly-extended arm 20. having a pin-and-slot connection with a vertical plate 21 slotted at 22 to receive the shaft of the lower roll and provided with a pin 23 beneath which may be swung a cam flange 24 carried by an arm 25 pivoted on the shaft of the upper roll 26.

In F ig.- 6 each transverse spring 12 is provided at its middle with a vertical plate 27 slotted at 28 to receive the shaft of the lower roll and provided with a pin 29 beneath which'may be swung a cam flange 30 carried by an arm 31 pivoted on the shaft of the upper roll.

It will be readily seen that the detail of mechanism for connecting the springs with the rolls y e wide y varied,

' The hollow standards, as is usual in this art, form receptacles for the bearing blocks for the lower and upper rolls.

I claim as my invention 1. A wringer base comprising hollow end standards, two hollow oppositely-extended arms projecting from the ase of each standand with the inner ends of their interiors communicating with the interior of the adjacent standard, and a clothes apron extendmg between each side pair of said arms.

'2. A wringer base comprising hollow end standards, two hollow oppositely-extended arms projectin from the base of each standard with the inner ends of their interiors communicating with the interior of the adjacent standard, and a clothes apron extending between each side pair of said arms, each of said aprons having a medial hollow ridge the interior of which, at each end, communicates with theinterior of the adjacent hollow arm.

Inwitness whereof I have hereunto set my hand at Indianapolis, Indiana, this 5th day of August, A. D. one thousand nine hundred and thirty-one.
