The Schedule referred. toin thse Letters Patent and making part of the To all` `@ahorn it ntty'ccncern v d Be it `known that'I,`rGnonGE G. WRIGHT, of Lcroy, Medina county, Ohio, have invented'certainv new and useful Improvements in Glothes-Wringers; and I do hereby declare that theffollowing is a full, clear, and exact description of my invention, .reference bel `ing had to the accompanying drawing forming a part of this specification, and to the letters-of` reference marked thereon, of which drawingd Figure 1 is a side View offa portion oi' a wringer, showing my improvements;A

d `Figure 2 is an end lview ofthe same.

`Figure 3 is a detailsitle `view of the same.

x `lVly` invention relates `to certain improvements` in` the arrangement of y.the several parts of a clotheswringer, having then upper rollfhung on a pivoted lever, through which Itconsists, iirst, in arranging the pivot'of the lever `forfthe upper i'olllin oiybetween the Yplanes of the cylindrical surfaces ofthe points and bases ofthe teeth of the first intermediate gear, whereby `the variations ofdistance between the rolls, 'caused by dit- `ferent thicknesses et cloth passing-between them, simply causes a rolling of the second upon the first intermediate gear, without affectinglthe mesh of these gears, or causing ther'nto bind and impede the operation of'the machine.` 1

My inven ion .,consists, j secondly, in arranging the pivot of `the second intermediate gear above aline drawn from thepijvot of the lever for the upperroll,

'tangent to the upper. surface of the periphery of thc gear on said roll, wherebylthe Apoint 'of contact between the second' intermediate gear and the gear on theupper roll is brought above the axis of the upper roll, so thatv the tendency of .the second intermediate gear `to lift the Yupper roll, instead of act-ing wholly to produce arotation of said roll, is materially dimin-` ished, and acorresponding economy `of ,power is cf-` fected.

` To enable .others skilled in the -art to rnake and use my invention, I willproceetl to describe -its construction and operation. y

In the annexed drawingsd `L represents the lowerframe-.pece of wringer, to

which is secured the sideiplate M, through which is passed .the shaft II of, tl1`e lower, roll, a vsemicircular groovebeingcut in the piece L4 to let said shaft down into the position shown. ,d

The upper end oftheplateM is made `in Aa semicircular form, and fits in between the level-F and thc i `swelled portion Oofjt-he side plate N, von the lever I the pressing power isapplicdf and provided with Vgear-wheels on the roll-shafts, and

, `with two intermediate gear-wheels to unite the rotai `tionoftherolls;andV .1

F, where it is secured by a screw, E, which forms the pivot for the said lever. .Y

The. forward portion of the plate-N is drilled vto form a box for the shaft G of the upper roll, which shat't also fitsv in a semicircnlar groove in the under side ot' the lever F, as seenv in Jig. 2.

`The press-screw I is passed through thc rearend of the lever F, and has an end bearing on the cap J of the rubber block K, which rests on theframe piece l L, from Vwhich it isevident that by turning down the .screw I the pressure on the rolls may be regulated as desired.

lhe gears yG and D are secured on the shafts Grl x .and H of the upper and lower rolls, and the first intermediate gear A is secured on a pivot, e, which is formed onthe block X, where it is secured by a bolt extending through the plate M, as shown in fig. 2.

. The second intermediate gear B is secured on the .pivot a, which is formed ou the block '1, where it is held` by a bolt extending through the plate N, as shown in fig. 2. Y j ,i

i The power is applied by a crank, not shown in drawing, secured on the shaft H ot' the lower roll, which is extended for this purpose, as indicated in iig. 2.

The intermediate gear is most conveniently made of the same size, and of a diameter from one and onehalf to two times as great as that of the diameter of the gears G D on the rolls, 4which veniently'made of the same sizel The .pivot E of the level' F, for the .upper roll, is placed between the planes of' the cylindrical surfaces k and l of points vand bases of 'the teethfof the` first intermediate gear A, as show n in Iig. 3, so that, as

the .distance between the rolls is varied by different thicknesses of cloth passing between them, the pivot a' of the. second intermediate gear B'describes an arc of a circle, fg, having its center at the pivot E, from which it is evident that by placing the second intermediate gear so as to leave a smallspace between the points of the gear B, and the gullets of therteeth of the gear A, when the rolls are at a medium distance from each other, the gear B can move from thelower point ofcontact, i, to the upper point .7, without injnriously aii'ecting the mesh of these gears, or causing them to bind to any extent.

. The pivot a of the second intermediatev gear B is arranged ata considerable distance above the line E c, drawnfrorn the pivot I] of the lever F, for the upper roll, `tangent to the gear G, on said upper roll, at c, from whichit is seen that the point ot' contact, t, between the second intermediate gear B and the upper roll gear vC' is brought considerably above the4 axis d of the upper -rol1, so that the rotation ofthe gearfB inthe direct-ion lindicated byarrow, has but gears are also con-1.

little power to raise the gear O and the upper roll, butfacts almost wholly in producing the desired rotation of said gear and roll, thus avoiding a' serious difficulty existing in other arrangements of this construction of wringers.

By this improved arrangement of parts, I obtain fixed pivots for both intermediate gears; one on the upper, and the other on the lower side plate, and still preserve the proper mesh between said gears without binding or cramping, within all reasonable variations of distance between the rolls, thus dispensing with the use of any swinging and connecting links between any of the gear pivots, or the use of slotted plates for the movement of the pivots of the upper roll and second intermediate gear, whereby Ilessen the cost4 and greatly increase the solidity of'. construction and the durability ofthe machine.

^ This improved arrangement also makes the ruachine much easier to operate, as the power is transfer-red and applied through the gears with much less loss of leverage, and with less axle friction than in any previous arrangement.

Having thus fully described my invention, I do not claim hanging the upper roll on a pivoted lever, nor

the use of two intermediate gears for gearing to- Kaese gether the upper and lower rolls, as thesefeatures have been before shown; but

"Wha-t I do claim herein as new 'and of my invention, and desire to secure by Letters Patent, is-

1. The combination of two wringer-rolls with end gear' and with two intermediate gears, the upper roll being hung in a pivoted lever, operated by set-screw and spring, and the pivot for said lever being arranged in or between the planes of the cylindrical surfaces of tbe bases and points of the first intermediate gear, substantially as and for the purpose specified.

2. The combination of ltwo wringer-rolls with end gear and with two intermediate gears, the upper roll being hung in a pivoted lever operated -by set-screw and spring, and the pivot of the second intermediate gear being arranged above a line drawn from the pivot of the lever for the upper roll, tangent to the upper surface of the periphery of the gear on said roll, substantially as and for the purpose specified.

As evidence of the foregoing, witness my hand this 25th day of February, A. D. 1870.
