'CLOTHES-WRINGER.

SPECIFICATION forming part of Letters Patent N 0. 610,882, dated September 20, 1898.

Application filed March 29, 1898.

Serial No. 675,609. (No model) To aZZ whom it may concern.-

Be it known that I, W'ILHELM AAB, a citizen of the German Empire, residing at New Ulm, in the county of Brown and State of Minnesota,have invented certain newand useful Improvements in Clothes-WVringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in clothes-wringers and the like.

l he object of my invention is to provide a wringer which will be simple in construction,

With these and some other objects in view, which will be obvious to those skilled in the art, my invention consists in the features, details of construction, and combination of parts, which will first be described in connection with the accompanying drawings and then particularly pointed out in the claims.

In the drawings, Figure l is a half front elevation and half sectional view, partly in elevation, of a wringer embodying my invention; Fig. 2, a detail rear elevation of a part of the same; Fig. 3, a detail section on the line 3 3, Fig. 1; Fig. 4, a detail section on the line i 4, Fig. 3; Fig. 5, detail views of the rubber shoe; Fig. 6, an end elevation of the wringer, the gears being removed and the clamp opened; Fig. 7, a similar view with the gears in place and the clamp closed on a tub; Fig, 8, a top plan View of the complete machine attached to a tub, a part only of the latter being shown; Fig. 9, a detail plan view of one of the roller-bearing shells; Fig. 10, an elevation and edge view, respectively, of a guardplate; and Fig. 11, a detail view of one of the tension-levers. I

Referring to the drawings, A are side plates, each having a slot or notch, as shown by dotted lines at a, Fig. 7, a foot-piece a, provided with a flange a at right angles to the plane of the side plate, said flange having a dovetail cross-section, an arm a expanded to form a rest, upon which is a centrally-arranged lug a extending upward, and a standard a whose upper end is offset inward, as shown inFig. 4c, and provided with an outward-extending hollow stud a, threadedinteriorly. The side plates are also each provided with concave B, provided with a front apron B and a rear apron E the two aprons and the concave being preferably formed of one piece, which may be either of sheet-ir0n or cast-iron. If of sheet-iron, the concave and aprons are secured to the sideplates in any suitable way. If of cast-iron, the concave, aprons, and side plates are preferably cast integral with each other.

Upon each flange a is slid a shoe 0, Fig. 5, of rubber, having a dovetailed groove c,wl1ich receives the dovetailed edges of the fiange,and also provided with a spring 0, which has one end secured in the lower end of the shoe 0 and its other end bent upward to bear yieldingly against the rear surface of the flange a the free end of the spring being bent outward to render it easy to slip the shoe onto the flange without the annoyance of having the free end of the spring hit the bottom of the flange a (See Fig. 1.) I

Upon the hollow studs a are placed tensionlevers D, each provided with a slot 01 in its front end, said slots opening downward. The rear ends of the tension-levers are each provided with an enlarged portion 61, Fig. 3, having a screw-threaded hole arranged. in a vertical plane and adapted to receive a thumbscrew E, Fig. 6, the lower ends of the thumbscrews being provided with ball-shaped projections e, each adapted to enter and turn freely in a hole in a cap or plug 6, inserted within the upper end of a spiral spring E, whose lower end rests upon the expanded portion of the arm a and is held against displacement laterally by the upward-extending lug a On each stud a is mounted a clamp-lever F, held upon the stud by ascrew f, threaded into the hollow stud and provided with ahead .Wide enough to engage the clamp-lever and thereby hold it in place, while at the same time permitting it to swing freely on the stud a Each clamp-lever F carries at its lower end a jaw f, connected to the said clamp-lever by a knuckle-joint, as indicated at f each jaw being substantially opposite and arranged to act in conjunction with the corresponding rubber shoe 0 for a purpose hereinafter described.

The upper end of each clamp-lever is provided with a toothed segment f while the rear edge of the clamp-lever, intermediate the segment f and the stud a is provided with a ratchet-toothed rack f, Fig. 7, for a purpose hereinafter pointed out. The outer face of each clamp-lever is provided with an outward extending pin f. A similar pin (2 projects outward from the outer face of each tension-lever D. The purpose of these pins will presently appear. Upon each hollow stud a outside the respective tension-lever D, is mounted a clamp-operating lever G, having an offset handle 9, a block g being located on the inner face of each clamp-operating lever G at the angle of the offset, as shown in Fig. 2, each block being provided with a screw threaded hole. That part of each clamp-operating lever G around the stud a is provided at one part with a toothed segment 9 and at another part with a shoulder 9 the toothed segment 9 being arranged to mesh with the toothed segment f on the clamplever, while the last tooth g and the shoulder 9 form stops which come into contact with the corresponding pin 6 on the tension-lever D, and thereby limit the movement of the clamp-operating lever G. That portion of each clamp-operating lever G around the stud a has a thickness greater than the amount of projection of said stud, and into the latter is threaded a screw whose head is greater in diameter than the stud a and enters a countersunk portion in the clampoperating lever, whereby the inner face of the screw-head is brought in close contact with the outer end of the stud, while the outer face of each screw 9 is flush with the outer face of that portion of the clamp-operating lever which carries the toothed segment 9 (See Fig. 4..)

Into the hole in each block g of the clampoperating lever G is threaded a screw or stud g, on which is pivotally mounted a pawl-arm H, having a pawl h, arranged to act in conjunction with the ratchet-toothed rack the outer face of each pawl-arm having an outward-extending wing orthumb-piece h, to which is secured one end of a spiral spring h whose other end is secured to the pin f on the clam p-lever, whereby the pawl is normally held in contact with the rack f.

In the slots a are mounted roller-bearings formed of a cylindrical shell I, Fig. 9, flattened at two diametrically opposite portions iintermediate the length of the shell, these flattened portions formin grecesses into which enter those portions of the side plates A adjacent to the respective slots to, whereby the shells I are held to the side plates in a manner to prevent rotation and longitudinal movement and yet to allow ready removal and insertion. Through the center of each shell I passes the respective gudgeon 7c of the lower wringer-roll K, these gudgeons being smaller in diameter than the interior of the said shell I, a series of antifriction-rollers 2" being inserted into the shell around the gudgeon and serving as a roller-bearing for the respective gudgeon.

Between the roller-bearing and the roll K is placed oneach gudgeon a guard-plate L, said guard-plates being each provided with front and rear outward-flanged edges Z Z, rounded at the inner corners, the guard-plates each having a slot Z in their upper ends.

In the slots din the tension-levers D are mounted upper roller-bearings similar in all respects, except the diaphragm I, hereinbelow described, to those previously described for the lower wringer-roll K, said upper bearing receiving the gudgeons m of the upper wringer-roll M, the gudgeons m of the latter passing also through the slots Z in the upper ends of the guard-plates L, which lie inside theside plates A and serve to prevent the rollers 'i of the lower roller-bearings from leaving the cylindrical shells in an inward direction, while at the same time preventing clothes passing through the wringer from getting off the rolls and entering the spaces between the ends of the rolls and the side plates. The rollers of the upper roller-bearings are prevented from moving inward by a plate or diaphragm 1, formed integral with the upper shells. (See Fig. 1.)

Upon the gudgeons at each end of the machine are mounted two intermeshing gearwheels N N, which fit closely against the cylindrical shells I, and thereby prevent the antifriction-rollers from shifting outward. These gear-wheels N N are constructed in the manner common to clothes-wringersthat is to say,with two sets of teeth on each gear-wheel, the teeth of one set being intermediate those of the other set.

One of the upper gudgeons m and the lower gudgeon at the opposite end of the machine are extended some distance beyond the cor responding gudgeon of the coacting roll in order to receive the usual crank 0, provided with a handle 0 and arranged to be normally secured to either of said extended gudgeons, whereby the machine may be operated from either end.

It will be observed that the upper roller M is smaller in diameter than the lower roll K, whereby when the crank O is attached to the upper gudgeon the power required to operate the wringer is considerably reduced, though the speed, of course, is also reduced. when thin clothes are being run through the wringer, the crank 0 may conveniently be put upon the lower gudgeon, as the power then required to operate the machine will not be excessive. WVhen heavy articles, such as blankets and the like, are to be run through v the machine, the crank 0 may be placed upon the upper gudgeon, thus saving the arduous labor otherwise necessary to turn the crank. The upper roll M is made of a cylinder m, cast around or otherwise secured upon the IIO shaft, whoseprojecting ends m form the gudgeons for the roll. The exterior of the cylinder m is covered with the usual rubber coating or jacket m The lower roll K is composed of ahollow cylinder provided at each end with a head k riveted to the'said hollow cylinder and having central openings through which passes the shaft,wliose projecting ends form the gudgeons k of the lower roll. The cylinder is also is provided with a rubber jacket k The heads 70 are fixed tothe shaft, which passes through them, by suitable means, such as a key To use my improved device, the pawl-arms H are first pulled out of engagement with the racks f and the handles g of the clampoperating levers G pushed down, thereby swinging the jaws f away from the rubber shoes 0. The machine may then be placed on the washtub P or the like and the handles graised to swin gthe jaws f into close contact with one side of the tube, whose opposite side is engaged by the shoes 0. The pawls 7b of the pawl-arms are held into contact with the racks f by the springs h whereby the jaws are locked in their positions of close contact with the tub.

The tension of the upper roll is regulated by adjusting the screws E, thereby compressing the springs E more or less, as may be necessary.

The crank 0 may be applied to either end of the machine and turned to operate the rolls. The clothes may then be fed between the rolls in a well-known manner.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a wringer, the combination, with a side plate having an upward-extending arm provided with an offset from which projects an outward-extending hollow stud, of a tensiou-lever fulcrumed on said stud, a clampoperating lever also fulcrumed on said stud outside the tension-levenanda screw threaded into the hollow stud and having its head countersunk into the clamp-operating lever.

2. In a wringer, the combination, with a side plate having a downward-extending foot provided with a flange, of a rubber shoe having a dovetailed groove arranged to receive said flange, and a spring secured to the shoe and projecting into engagement with the flange.

3. In a wringer, the combination, with a clamping-lever having a toothed segment at one end and provided with a rack, a clampoperating lever provided with a handle and with a toothed segment engaging the segment on the clamping-lever, and a pawl-arm pivoted to the clamp-operating lever and provided with a pawl arranged to engage the rack on the clamping-lever, of means for holding the pawl in position to engage the rack.

4:. In a wringer, the combination with a clamping-lever having a toothed segment at one end and a rack on one edge, a clamp-operating lever having a handle, and a toothed segment engaging the segment on the clamping-lever, and a pawl-arm pivoted to the clamp-operating lever and provided with a pawl arranged to engage the rack on the clamping-lever, of a spiral spring having one end connected to the pawl-arm and the other end to the clamping-lever.

5. In a wringer, the combination, with a side plate having a slot, a tension-lever fulcrumed on the side plate and also provided with a slot, and rolls provided with gudgeons, of cylindrical shells each'having opposite recesses intermediate their ends and arranged to receive the portions of the side plates and tensionarms, respectively, adjacent to their respective slots, said shells to be arranged to receive the respective gudgeons, and antifriction-rolls between the gudgeons and their-shells.

6. In a wringer, the combination, with a pair of rolls having gudgeons, of a'guardplate provided with a hole arranged to receive one gudgeon and with a slot arranged to receive the corresponding gudgeon of the other roll, a cylindrical shell surrounding the former gudgeon and antifriction-rollers Within the cylindrical shell and around the said gudgeon, the inner endof thecylindrical shell being open and in contact with the guard-plate whereby the latter serves to prevent the longitudinal movement inward of the antifriction-rollers.

In testimony whereof I affix my signature in presence of two witnesses.

WILHELM AAE.
