WRINGER.

Application filed December 20, 1921.. Serial No. 523,748.

10 all whom t may con-cern:

Be it known that I, GEORGE IV. Lnwis, a citizen ofthe United States, and resident of Grinnell, in the county of Poweshiek and State of Iowa, have invented a certain new and useful Vringer, of which the following is a specification.

In connection with the use of clothes wringers, and particularly with the wringers that are operated by powerl instead of by hand, it sometimes occurs that garments be come caught and entangled in the wringer rolls, or that the operators hand becomes caught between the rolls, .and in such instances' itis desirable that some means be provided for instantly separating the wringer rolls.

My object is to provide a wringer for power-operated machines, of simple, durable and inexpensive construction, and. in which the upper wringer roll may be instantly separated from the lower one by either a direct push or pull upon a bar of large size so located that it is readily accessible to the operator, and my further object is to provide a wringer deviceof this character in which, after the upper wringer roll has thus been released, it may be replaced quickly and easily and without the necessity of readjusting the spring tension devices with which these wringers are equipped, so that the operator may promptly continue the use of the wringer, and without the delay incident to readjustmcnt of the tension devices.

A further. object is to provide an improved drain board for wringers, of simple," durable and inexpensive construction, that may be readily, quickly and easily shifted to drain water in either direction and 'to deliver the Vwater to a considerable distance from the wringer in either direction without making the drain board of unusual or excessive width.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects con-V templated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure/1 shows a front elevation of a wringer embodying my invention.

Figure 2 shows an end elevation of same.

The dotted lines show the upper roll in its elevated position, and the spring tension device lowered out of the way.

Figure 3 shows an enlarged detail view, partly in section, illustrating the means for automatically pressingthe tension springs when the upper roller is returned to its normal position; and

Figure 4 shows an end elevation, on a reduced scale, of the end opposite from that illustrated in Figure 2.

Referring to the accompanying'drawings, I have used the reference numeral 10 toindicate the main supporting frame of the lower wringer roll, the lower roll being indicated by the reference numeral 11'. On the side opposite from the main frame member 10 is a frame member 12 for the lower wringer roll. This frame member 12 is firmly connected to the frame member 10'y by two stationary rods 13 and 14:, which extend across from the frame member' 10 to the frame member 12 at one side above and below the wringer rolls.

In the front face of each of the frame members 10 and 12 is a bearing member 15. In each ofthese bearing members is mounted an upright shaft 16, having a horizontal extension-at its lower end extended through said bearing. The upper end of each of these shafts 16 is reduced, as shown at 17 in Figure 3, and on the reduced portion is slidingly mounted a latch device 18, having its lower surface rounded, for purposes hereinafter made clear.

For the upper wr'inger roll 19'tliere are two frame members, one being indiated by the numeral 2G and the other by the numeral 21.' Each of these is provided with 'a lug 22, which is pivotally mounted upon the rod 13. The frame member 12 is provided with a horizontal shoulder 23, upon which the lower end of the frame member 21 rests whenV in normal position, as clearly shown in F igure4. Eachof ther frame members 20 and 21 is provided at one side with an outwardly extending arm 24 having a rounded depression on its top surface at 25, designed to receive the rounded latch device 18,.and also each of these arms 24 has an inclined top surface 26 extending outwardly and downwardly from the depression 25.

The wringer rolls have suitable bearings in the respective frame members, and they' are provided with coacting, intermeshing gears of the kind now in ordinary use and which I have not illustrated or described.

On the shafts 16 above the latch devices 18, I have mounted compression springs 27, and slidingly mounted on the said shafts, above the compression springs, is an actuating bar 28, and above this bar are the tension adjusting nuts 29. y l preferably permanently mark on one side of this bar the word Pull, and on the other side the word Push. The latter is not shown in the drawings.

In the operation of this part of the device, andassuming that the wringer is in its normal position for use, then in the event that it is desired to instantly release and remove the upper rollthe operator moves the bar Q8 so that the latch devices 18 will slide out of their depressions and down the inclined surfaces 2G of the arms 24 until tiey are free from said arms, whereupon the upper roll and its supporting frame members are free to swing upwardly on the pivot 13, as illustrated by dotted lines in Figure Then when it is desired to return the wringer to normal operative position, the operator simply grasps the bar 28 and moves it back to its normal position. Vvlhen near the end of this movementthe latch devices 1S will engage the inclined surfaces 26 of the arms 2%, and upon further movement of the bar 28 the springs 27 will be compressed and the latch devices will finally enter the depressions 9.5, and when they are in said position the tension of the springs will be exactly the same as it was before the operation of releasing` the upper roll, so that no new adjustment of the springs is necessary.

My improved drain board device comprises a drain board body portion 30, which is shaped to enter between the lower ends of the frames 10 and l2. On its under surface, near each end, is a lug 31, and on one of its sides, near each end, is a bolt opening 32.

T he wringer isl provided with a latch bar comprisiny a body portion lts ends are straight and are slidingly mounted in the lower ends of the frame members 1() and 12. On one end of the latch bar 83 is a lever Se;

for pulling the latch bar out, and near the other end is a spring for moving it in the opposite direction. To engage one end of this spring 35 l have provided an arm 3G which encircles the latch bar 33 and is then extended upwardly and outwardly through the frame 10. This arm at one end, and the latch bar at the other, form the supports upon which the drain board is slidingly supported, and for the purpose of holding the drain board at either limit of its movement l have provided a slide bolt 37 mounted in the frame 12 and designed to enter one of the openings 32 in the drain board.

In practical use with this part of the device, and assuming that it is desired to adjust it, the operator pulls out the slide holt 37, whereupon the entire drain board is free to slide on its supporting members and 33 from one limit of its movement to the other. W hen it reaches one limit of its movement, it will be stopped by Ahe lugs 251, and then when it is tilted in the proper direction for use as a drain board the slide bolt 37 is inserted in the opening 3&2 and then the drain board is securely locked in this position.

By this arrangement l have provided a very simple and inexpensive construction, by which the drain hoard is firmly supported when in use, but capable of both pivotal and sliding movement when the slide bolt 37 is removed.

l claim as my invention:

ln a wringer, the combination of a lower roll, a frame in which the lower roll is supported, an upper roll, a frame in which the upper roll is supported, said upper roll frame being pivotally connected to the lower one so that when moved on its pivot the upper roll will be separated from the lower roll, a tension device comprising an upright rod pivoted at its lower end to the said lower roll frame, the upper end of said rodbeing` provided with a contracted portion, the upper end of which is screw threaded, a latch device rotatively and slidably mounted on the said contracted portion, a nut for said screw threaded portion, a spring` on said contracted portion between said nut and said latch device, said latch device having` its under surface rounded, a pair of lugs eX- tending laterally from each enti of the frame of the upper roll, said lugs being spaced apart to receive the upwardly extendingl rod between them in such a manner that the rounded surface of said latch device will engage their upper edges for yieldably supporting the rolls of said frame members together.
