TO ALL WHOM 4IT MAY CONCERN:

Beit known that I, ROBERT B. HUGUNIN, of the city ot' Cleveland, countyof Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Clothes-Wringersz and I do vhereby declare that the following is a full, clear, and exact descripti'oh ofthe same, reference being had to the accompanying drawings, making a. part'ot this specification. i This invenition consists in' the arrangement and combination of three single Aand one double gear-wheel, arranged as follows: One singlegeur wheel on the shafts of each of the 4rubber rollers,vthe lower one moving on the outer surface and the-upper one on the inner surface of the rim of the double-gear wheel; The double-gear wheel is secured to the lower shaft by toggles, or their equivalents, passing over the pivot'shaft, passing through its centre, thence over thelower shaft. On the pivot shaft between these toggles'a single cog-wheel, or its equivae lent, a; roller, runs loosely. This eogacting on the back of the cog on the upper shaft keeps it in constant adjust'- ment with the `teeth on the double-gear wheel when`the rubber rollers are pressed opariz. The toggles keep the double gear in adjustment with Athe cog on the lower shaft'. Also, in the arrangement and combination of two -wooden or other bars attached together near their centres by two bolts with rubber spring colla-rs under the heads and nuts of the same, and. groovedjournol blocks and two adjusting screws. The upper vhar when' in'position in the frame'rests its ends en the tops of the journal blocks, which are grooved on their inner sides to correspond with the ends of the lower bor, which ends move up and down in said grooves. These grooves lsteady the lower bar, which, in turn, steadies the journal blocks and prevents them-from falling in at the top. In'use, two adjusting screws nre used, passing down through the stiifening piece passing across the top oi' the frame, then down, loosely, clear through the upper spring bar, resting their points on the top of vthe lower'spring bar. which, being pressed downnt eachend, pulls.down, .by means ofthe two bolts,otho upper bar on to the journal blocks, which in turn press `the elastic rollers together. The elasticity of the rubberV collars and wooden bars, as arranged and combined, give to the rollers power to accommodate themselves to the thickpess-of cloth passing between them in wringing. In the drawinge l Figure 1 shows my wringcr arrangement and combination complete ns in' use.'

Figure 2 shows an end view of the elastic rollers, spring bars, journal ,block,y&c.

bolts, rubber collarsundertheil; heads and nuts, journal blocks, and two adjusting screws. Figure 4 shows a section of the beck part of the frame. i

Figure 5 shows my self-adjusting gear-wheels and toggles. Figure-@View of spring bars and journal blocks disconnected from the frame. To enable those skilled in the art to'i'ully understand my invention, I will proceed to describe itsconstruction and operation.

Similar letters of reference indicate corresponding parts in ull the figures.

In the-drawings, A. represents a double-gear wheel, or one with teeth on the innerv und outer 'surface of its rim. B is a single-gear wheel firmlyv secured to the'shaft ol` 4the driving or lower roller, and-working on the outer surface of the'rim of the wheel'A. C is a simil'r wheel to B, only smaller than'it in proportion as the outer diameters of the wheels A and B, Sie., so lthat uniform ru'pditymay be obtained in turning the two rollers.

' The wheel C is secure-Ll firmlyto the end ofthe shaft of the upper roll. D is a small single-gear wheel running loosely ou the pivotl passing through the centre ofthe wheel A.v It nets as a backing to the wheel C, kecpingit in constant adjustment with the wheel A, wit-hout -toggles from the wheel A to the upper shaft. EE, toggles for keeping the wheel A in'position, as well as in adjustment with the wheel B, on the lower shaft. F, pivot shcftv'of wheel A; one 'end of 'che to-ggles is secured to this shaft. G, upper or-driven shaft'. H ILjournal blocks. I I, groovesonthe innersides ofA the same. JJ, projections of. the journal blocks, to prevent them Figure 3 shows the front side of the upper part of one of my wringers, also arrangement ofthe spring hars,

from working ontwurilstln'ough the slots Aof thc end pieces of the frame in which they move. K, lower bar or spring-piece, made narrower at its ends to fit the grooves I I in the journal blocks, in which its ends move, and by which they are guided. This bar also steadies the journal blocks and keeps them in an upright position. L, upper bar or spring-piece, narrowed down nt its ends to lit loosely thc slots in the end'pieces ofthe frame. This upper bar rests on the lons ot' thejournn-hlocks, directly undcrthe stiifening piece going across the topof the frame, and through which the adjusting screws pass. M M, ordinary bolts and nuts used to loosely attach together the two bars K and L. vThese bolts pass clear through these bars, about half way from their ends to their centres. N N, small rubber springcollars used under the heads or nuts of the boltsV M M, on the upper sid'euofv the bar L, anni lower side of the bar K. O O, adjusting screws passing down through the stiffening piece, and loosely through the bar L to the bar K, where the points oi' these screws rest. The screws O 0 pass through screw'plates on the under sirle of the stii'ening piece; their points rest on a small metal plate on the top side of the lower bar K. In use these screws press (loivn the ends of the lower bar, and bylmeanso'f the bolts M M this pressure is conveyed'to the upper bar L, which in turn, restingon `the tops o'f thejournal blocks, gives pressure to' the upper roll. For ordinary purposes, perhaps no rubber spring collars,in addition to the bars'K L', would be required. P,stiil`enng bur 'bolted across the' top of the frame. Q Q, end pieces of the frame. l R R., straight slotsput in the end pieces of the frame to accommodate thestiffening bar, springv bars, journal blocks, and journal of Athe rubber rollers. S S, slots cut'in the ends .of the end pieces Q Q, to t over the tub or box. T T, strengthening bolts. U U, side pieces for sti'euing the frame and guiding thc clothesr in i'vringing. V V,niovable clumps for fastening the machine tothe tub or box.

` In operation this machine is used as other wringers.

Having thus describedimy invention, what I claim, and desiregto soeur-e by Letters Patent, is@

- 1. I claim the arrangement and combination of the doubleLgear wheel A and vsingle-geur wheels B, Cfand' 1D, and toggles E E, or their equivalents, as described, for the purposes specified.

2. I claim the arrangement and combination of the stiening bar P, spring bars K and L, bolts M, spring collars N N, and adjusting screws O O, as described, for the purposes specified. v R. B. HUCNJNIN.,` Witnesses J. K. HAMILTON, L. H. SAnGuNT.
