.To @Zt whom it may con/cern:

Be it known that I, JOHN W. Wnisna, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in W'ringers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the let ters of reference marked thereon, which form a part of this specification.

O ne part of my invention relates to improvements in clamping devices of that class of wringers which are provided with a hinged table connected with the clampingjaws of the wringer in such manner that the jaws may be opened and closed by the movements of the table.

My invention also relates to improvements in the devices for supporting and forcing together the wringer-rollers, and in other details of construction in wringers, as will hereinafter appear.

Figure l represents in perspective a clotheswringer embodying the features of my invention, with certain portions of the wringer and its adjuncts broken away, so as to more clearly illustrate the invention. Fig. 2 is a section on a plane parallel with theframe-sides, as indicated by the indirect line X X of 1, and represents, partly in section and partly in elevation, one of the vertical side pieces with a pair of pendent jaws, said view illustrating the inner side of the side piece. In this view the upper bearing-block is also shown partly in section. Fig. 3 is a detail section taken longitudinally through one of the slides provided for connecting the table with the camyoke portions of the movablejaws, said view being alsovtaken through the support for the slide and the canryoke end of a movable jaw,

as indicated by the line X X of Fig. 2. Fig. 4 is a sectional view taken upon the indirect line X X of Fig. 3, showing in side view one ofthe spriug-controlled slides and the plate for supporting said slide at one end of the table.

The elastiofaced wringer-rollers A and A are arranged between the sides Bof the wringer-frame, and the lower roller, A', of this pair of rollers is operated by means of a crank, A2, at one end of the machine, as usual.

The devices for supporting the wringer at and upon the edge of the tub are in the nature of two pairs, C, of jaws or clamps, one pair of which is arranged at the lower end portion of each one of the two sides of the wringer-frame. These two pairs of jaws are practically situated in a plane back of the plane occupied by the rollers, so as to bring the rollers over the tub when the wringer is properly secured thereon, and to such end the lower end portions of the sides of the frame are adapted to form a pair of horizontal rear extensions, b, from which vthe said jaws depend. The fixed jaws C are rigid with these rear extensions, b, of the frame-sides, and can be conveniently cast integral therewith, while the movable jaws c are pivoted to the said extensions in position to admit of their being moved to a desirably-close proximity to the fixed jaws.

The incline or table D, upon which the wrungout clothes are run orf toa suitable distance from and beyond the rollers at what may be termed the rear side7 of the machine, is pivot-ally hung or supported between the rear extensions, b, of the sides of the frame, the approved mode of pivoting or hinging the table being to hang it at points adjacent to its inner edge upon a tie-rod, d, which, While serving as a pivotal support for the table, also serves as a means for connecting together the sides of the wringenframe at their lower ends. The extensions b are preferably made with marginal inwardly projecting anges extending partially around the edges thereof, so as to form upon the inner or adjacent faces of said extensions recesses b, each adapted to afford sufiicient area of working space for the upper end portions, c', of one of the pivoted jaws. Each movable jaw cis piv oted against the inner side of one of said` rear extensions of the frame-sides, as at ci, a w1 is permitted to vibrate to a limited extent through a space or opening, b, formed by the absence of a portion of the flange at the lower edge of each one of the said extensions b. Fach movable jaw has its upper end, c', made somewhat in the form of a yoke, and is pivoted at a point below and eccentric to the table-pivot by means of a pivot, c2, which passes through the jaw substantially at the point of junction between the middle of its yoke- IOC shaped end and its pendent clamping portion. The inner sides of these yokes are adapted to practically constitute cam-surfaces, over which the lugs at the ends of the table ride when the table is swung up or down for the purpose of operating the movable jaws. The table is pivoted eccentrically to the movable jaws, and when swung to its lowered inclined position its end lugs serve to close the movable jaws toward the fixed jaws, so as to clamp the jaws sides of the yoke, and to thereby prevent the release of the jaws after the latter have been closed. t

As a practical and convenient way of backing the sliding lugs D by spring resistance and permitting alimited sliding movement on the part of the lugs,each lug is formed at one end of a slide-bar, D2, which is at its opposite endv provided with a lug, D3, arranged to abut against one end of an elastic spring block, E,

against the edge of a tub or other supportbe--eentined between the lug on the slide and a tween the fixed and movable jaws, as illustrated in full lines, Fig. 2, and, conversely, when the table is swung upwardly its end lugs serve to operate the movable jaws or move the same away from the fixed jaws, so as to open the jaws, as illustrated in dottedlinesin said figure. This operation of the jaws is effected by the action of the lugs against one or the other of the arms of the yokes, and as a means for locking the movable jawsin their closed position againstv the tub or other support, the inner side of each yoke forming a cam-surface, as hereinbefore mentioned, and the lugs D', backed by springs E, and arranged to slide to a limited extent in such manner that when thejaws come into contact with the edge of the tub or other supportin the operation of swinging down the table to close the jaws the lugs may yield backwardly by the compression of the springs under the action of the cam-surfaces of the yokes upon said lugs. By this construction the jaws may ob viousl y act with a yielding pressure, and will adjust themselves to the thickness of the edge of the tub or othersupport to which the wringer is attached. Said camsurfaces are preferably arranged to approach nearest the pivoted axis ofthe table at their parts which are engaged by the lugs when the table is about horizontal, whereby the springs will be compressed to the greatest extent before the table reaches its lowest position, so that after the lugs in their passage over the said camsurfaces have reached the points mentioned a further downward movement ofthe table will carry thelugs upwardly to the parts of the cam-surfaces more remote from the pivoted axis of the table, and so as to allow a slight expansion of the springs. When the lugs are in this position, it obviously' becomes necessary to slightly compress the spring-sin turning the table upward, and the table and clamp-jaws are thuslocked,and cannot become accidentally loosened. As herein shown, the lugs bear upon parts c3 of the cam-surfaces of the yokes when the jaws are locked, as above described, said parts of the cam-surfaces being in the particular form ot' the device illustrated practically straight.

Obviously any conformation of the yoke which will cause the lugs to bear against one side of the yoke with a gradually-increasing pressure when the table is swung down will serve to effectively hold the said jaws in a closed position, the particular cani curvature herein shownv being desirable to avoid any ac'- cidental slipping of the lugs along the inner lug, f, formed with one of the end plates, F, of the table. The spring is conveniently held between the sliding and fixed lugs by means of a bolt, f', passing through the lugs and the spring and secured to the lug D3, the bolt being adapted to slide through the fixed lug f, so as to permit the spring to be compressed when required.

The slide-bars D2 are each provided with a longitudinal slot, d', in which is received a short rib, f2, on suc-h one of the end plates, F, as the slide-bar is movably held against. These ribs serve as guides for slide-bars, and are made shorter than the slots in the latter, so as to' permit the required extent of longitudinal play on the part of the slide-bars or slides at such times as the slides are moved back against their spring resistances by the cam-yolresy or thrown forward by the expansive action of the springs.

rlhe end plates, F, of the table are also each provided with a lip,f, along one edge, and with a wide fiat portion, f4, at its inner end, said lips serving as auxiliary guides for the slides, and the flat portions f 4 serving to close the recesses b', in which the cam-yokes are arranged, as best shown in Fig. l, in which a portion ofthe table is brokenaway at one end so as to expose a portion of one of said end plates.

The end plates are double-anged or otherwise formed on theirinner sides, so as to provide groovesfi, in which the ends ofthe board or boards comprising the body of the table are tted and held. These end plates are drawn together and held against the ends of the board or boards by a tie-rod, f6, and, as herein shown, the table is conveniently'composed of two boards, between the meeting edges of which the pivot d passes, it being seen that by grooving the boards along their meeting edges a suitable passage can be formed for said pivot.

The blocks G, on which the lower wringerroller, A', is journaled, are fitted in approximately V-shaped seats formed between the lower converging ends of the edge flanges b3 of the vertical metal sides B of the wringerfrarne, while the upper pair of blocks, G', in which the...upper wringer-roller, A, is journaled, are arranged to slide in the spaces formed between the said flanges b"3 above the block G. For these blocks or bearings I prefer employing wooden blocks well saturated with oil prior to their incorporation in the machine. By thus employing oil-saturated wooden or analogous oil-saturated blocks the jour- IOO IIO

nals will run easily therein, and at the same time the application of oil from time to time as a lubricant be avoided, thus entirely obviating such uses of lubricants as have heretofore tended to soil the various articles passing through the wringers.

The upper roller is held down by a yielding spring-pressure derived from a pair of spring devices, H, arranged upon the top cross-bar, B', of the wringer-frame. These spring devices are held between the top cross-bar and the inner arms of a pair of levers, I, which are pivoted on the top cross-bar with their outer ends maintained by the action of said springs against the top ends of a pair of slide-rods. K, respectively extending from the outer ends of the levers to the bearings for the upper roller. These rods work through apertures in the top ends of the sides B of the frame, and have their upper ends preferably received in suitA able sockets in the under sides of the outer arms or ends of the pivoted levers, so as to admit ofthe rods being turned about their axles for the purpose of varying the length of the rod between the levers and the bearings, in which latter the lower screw-threaded ends of the rods engage in correspondiugly-thread ed sockets. Each rod is provided with a thumb-nut, L, or other handle rigid with the rodv to permit the rod to be turned as occasion may require. By adjusting these rods the inner ends ofthe pivoted levers can be depressed or raised, so as to vary the spring resistance, and thereby vary the down pressure ofthe npper roller.

The spring devices each consist of a coiled spring, h, inclosing an elastic tube, 71.', thereby forming a strong compound spring. To cause the springs to be compressed in a direction coincident with their axles, a steel or other suitable metal rod, h2, is inserted in each tubular core 71.. These rods are of a less length than the springs, so as to `terminate short of the ends of the elastic tubular cores in which they are iitled, and are beveled at their ends, so as to prevent their catching on the elastic tubes when the springs are compressed.

In Fig. l a portion of one oi' the compressed springs'is shown broken away so as to expose one of the said rods. It will be seen that these rods will permit the longitudinal contraction and expansion of the springs, and at the same time will prevent the springs from being bent or bowed out laterally, thereby greatly increasing the efficiency of the springs.

I claim as my inventiond l. The combination,with the clamping-jaws of a wringer, of a pivoted table and means for actuating said jaws from the table, comprising a movable part or slide upon the table engaged with the jaws and having yielding or spring connection with the table, substantially as and for the purpose set forth.
