TO WHOM IT MAY CONCERN: i

Be it known' that I, ALFRED M. BnInEY, of Midd-lefield, in the county ofMiddlesex, and State of'Conhecticut, have invented certain new and useful Improvements in Wring'ing and other like Machines; and I hereby declare the followingto be a full, clear, and exact description of the same, reference being bad to the accotni- My invention relates to the springs, which in wringers, mangles, and similar machines are employed in order to bear upon the sliding-boxes in which the journals of -the upper or driven 1-ol1er are 'held, and thus insure the necessary pressure between the-two'rolls, at the same time thatprovisionis made for their yielding slightly, so as to conform to dilferent thicknesses of clothes. i I

Ina elothes-wringer of 'ordinary construction, the bearings of the springer the points where the ends-0f the spring are supported and held, are either immediately over the bearingsoi' the upper wringer-roll shaft or inside the frame of the machine, betweenthe two journals or ends of the shaft, which bear against the spring. This arrangement of the spring or springs is oneof the-causes which give rise to the tilting or rising of one end or the other of the upper roll, when the clothes to be .wrung are inserted nearsuch end of the roll.

It is well known that the tilting of the roll is a frequent source of trouble, detracting in some 'measure from the-successful'operatio n of the 'machine thecogs'upon the wringer-shafts are apt either to be thrown out of gear, or to become jammed and lock ed, and thus to prevent the rolls from moving with the steadiness and uniformity so desirablein machines of this class. i

' My invention is intended to-Iemedyand obviat'e the diiliculty above named, and to this. end it principally consists in combining the spring with the upper or the adjustable wringer-roll, in such" manner that the said roll shail bearupon'the spring at points intermediate between those upon which the ends of said spring are supported. In other words, the ends of the spring are extended on each side of the machine, beyond the bear ings of the upper or adjustable shaft, so' that the distance betweenth'e points of support of the said ends shall be greater thail that intervening between the points at which the-spring and shaft are in contact. V

' The invention further consists in the peeuliar constr uction of the spring, and.its' combination with the wrin ger-rolls and set-screws, for regulating the pressure in the machine, as hereinafter described.

To enable those skilled in the art to understand and mid my invention, I will now proceed todescribe the manner in which the 'sameis or maybe carried into effect, by reference to the accompanying drawings, in which- Figure 1 is aperspective view of a clotlies-wringer, made in accordance with my invention. v

Figure 2 is a longitudinal vertical central section of the same-' The machine there shown does not essentially differ in its general construction, and in the arrangement of the sliding-boxes a a of the upper shaft iii the frame B, from ordinary wringers. I' will therefore confine this description to the arrangement of the spring, and such parts as are directly afi'ected by it.

It has heretofore been usual, as's'tated in the former part of this specification, to support the ends ofthe' spring, either upon the sliding boxes a a of the upper roll, or at points intermediate between the two boxes.

Under this arrangement it will be seen, without further explanation, the clothes, when irisertedbetween the rolls near one end, for instance a, would have the tendency to tilt or raise that end of the upper roll, and coriseq'uen-tly to depress the other end-a, and so cause the clogging or jamming-of the cogs C. i In case the clothes were put in near the end a, the tilting action would be reversed, and the tendency would be to throw the cogs out of gear, and to cause them to work andwear unevenly.

By my invention, however, while the upper roll is leftfree, as before, to adjust itself to the varied thickness of the clothes to be wrung, it'is nearly if not' entirely prevented from tilting, and maintained parallel with the lower rolli The spring I prefer to employ in order to effect this result is shown plainly in fig. 2.- I It is compose d of two bars'or strips, 6 b, of wood,'or other suitable elastic material, which are held apart by means o-ipins or dowels 0, or blocks, or equivaleutmeans, for holding the springs apart, placed between them at-eaeh end The lower springbar, when in position in the machine, rests upon the sliding boxes aa', and the length of the elastic bars 12 is such that, when placed in the machine, their ends on each side will extend out beyond the boxes at a, as shown in the drawings, so that the latter bear upon the lower bar I), at points intermediate between the bearing-points c of the spring. When, therefore, clothes are inserted between the rolls, near the box a for instance, the box will be forced up against the spring, which will thus be bent between the points 0 a, so as to allow both the box a and the. box a, which also. presses (but only in a modified degree) against the Spring, to 'risew By this means the tilting of the upper roll is'in a great degree prevented, the parallelism of the rollsis, nearly it" not entirely maintained at all times, and consequently all clogging or uneven working of the cogs androlls is obviated. v 1 d The two bars I) b m'aybeof different elasticities, or, if desired, one bar only may be elastic, and the arrangemcnt of the' spring may be varied in many other respects, without departing from the principle of my invention,

solong as the essential feature'is preserved, of causing the upper roll to bear upon the spring at pointsintcb' mediate between the bearing-points e c of thespring.

In order to regulate the pressure of the rolls upon the article inserted between them, employ on each side of the frame regulatin -screws d, the lower ends of which pass through. holes formed in the ends of the cross-bar D of ,thevfran1e,i immediately above the boxosa a. In,these holes are placed screw-nuts e, whichhold the regulating-screws in position. i I v The cross-liar Dis held in the slotted or jawed side pieces B, in which the boites of the upper roll slide, and the space between the cross-bar andthe boxes is open, so as to allow the ends of the screws cZ to press directly. epon the upper spring-bar b, in the top of which is sunk a little metal disk, It, at the point where each screw comes in contact withthebar. By turning the screws in one direction or in the other, it will be seen that the Spring will be pressed upon the boxes a a", with any amount of force desired, and in this manner the pressure of therolls can be regulated with extreme ease. 1

Another-feature of this arrangement is, that the springis .not attached to the frame at all, bnt simply rests upon the boxes a a', in which position it is steadied by its ends,which pass through and project from the slotted side pieces B. By raising the screws d away from the springg the latter is released, and can be drawn out and removed from the machine with perfecttfacility, whenever dcsiredt for instance, when the machine is notin use, or when it is to be packed for transportation, rice.

It will be observed that thc dowels or pins 0, or other incans, which form the bearing-points of the spring, ar'e'not u nitedsolidly with the bars 6, but fit loosely or with a slight play in. the holes mortiscd for their reception in the bars, thus allowing thelatter to yield freely to pressure.

Having now described my invention, and the manner in which' the same is or may be carried into effect,

what I claim, and desireto secure by Letters Pat ent, is as follows:

1. In clcthes-wringers, and other machines in which t'wo rolls are required to operate atvnrying distances from each other, the employment of a spring, whose ends extend beyond the bearings-of -the upper ordriyen roll, in the manner described, so that the ends of said roll shall bear'a-gain'st the spring, at points intermediate bet-ween the bearing-points of said spring, as and for the purposes-set forth.-

2. In combination with'a spring whose bearing-points are located with relation to the points where it is in contact with the upper or driven roll, in the mauncr specifi ed, I claim the employment ofscrews, or equivalent devices, for regulating the pressure of the spring, arranged immediately above the points where the upper roll.

bears against the saidspring, as shown and set forth. 1 I .3. The herein-described combination and arrangement of the vspring. with the'uppcr roll,-t-hc' frame, and the regulating-screws, so that the said spring may be readily applied to or removed from the machine.

In testimony whereof, I have signed my name to this sp ecifieationbefore two subscribing witnesses,

' ALFRED. M. BAILEY.
