- periphery of the roll.

It is well adapted to use in dyeing and washing machines and wherever it becomes desirable to keep up a circulation of the liquid on the inner as well as the outer face 7 of the material passing around the roll.

In the accompanyii'ig drawings. Figure 1 is a view of the roll in side elevation, Fig. 2

is a transverse section in the plane of the line AA of Fig. 1, Fig. 3 is a partial longitudinal section, the section passing centrally through the end and part of the body of the roll. Fig. 4 is a view showing how the roll is arranged in use, the roll being shown in transverse section in the tank, and Fig. 5 is a view showing the roll in side elevation in the tank.

As herein illustrated, the roll com rises end hubs 1 and 2 provided with spo es 3 radiating therefrom and connected with rims 4 on which are applied retaining plates 5 for the reception of the ends of the circulating blades 6, 7. The blades 6, 7, are arranged in pairs as clearly shown in Figs. 1 and 2, the blade 6 extending inwardly a greater distance from the eriphery of the roll than the blade 7 and tie inner ends of the two blades being inclined toward each 6 and 7 extend longitudinally of the roll and are spaced from each other leavin a passageway 8 for the liquid to pass etween them and the succeeding pairs of blades are also spaced from one another leaving passageways 9,- for the entrance of the liquid from the exterior of the roll to the s ace within its peri hery. The spokes 3 w 'ch connect the hu l; with the periphery are flat and inclined in a lateral directionafter the manner of the blades of a screwpropeller for the pur ose of inducing a current of liquid from without through the endof the roll to the space within its periphery. The spokes at one,end are inclined in an. opposite i 16, 17, and thence over guide ro direction from the spokes at the opposite end, thereby tending to force the liquid in at the opposite ends while the several pairs of blades 6 and 7 tend to direct a current outwardly through the periphery. The inncr end of the blade 7 of each pair of blades 6, 7, tends to scoop the liquid within the periphery of the roll as the roll advances from right to left in the direction shown by the arrow, Fig. 2, thereby inducing a current of'liquid outwardly through the space between the blades 6 and 7 and hence into contact with the inner surface of the rope, chain or strip of material which may be carried on the periphery of the roll. The position of two such chains is indicated in dotted lines in Fig. 1, The blades 6 and 7 may be steadied in ther positions by spacing pieces 10 intermediate of their lengths.

The construction'is such that the liquid will readily flow in through the spaces 9 and will pass the blade 7 and be interrupted by the inner end of the blade 6 and be caused to pass outward-1y between the blades thereby eingforced into intimate contact with the inner face of the goods and passing around the chain or rope of fabric will again be drawn inwardly and so will alternately pass outwardly and inwardly through the perlphery of the roll as the latter is rotated within the liquid in which it is immersed.

The roll may be mounted in any Well known or approved manner, the means of mounting which I at presentprefer being stub axles 11 carried by a supporting frame 12 and entering within the hubs 1 and 2 of the roll.

The roll is simple in its structure and very eifect've for the purposes for which it is intended.

The rope or chain of fabric will rest on the outer edges of the several blades thereby leaving the greater portion of its interior surface cxposed to the liquid and thus materially expediting the scouring or washingof the fabric when it is used for washing purposes and insuring a very homogeneous shade of color when the roll is used for dyeing purposes.

The position of the roll when in use is illustrated in Figs. 4 and 5, the chain or rope of fabric 13 passmg as indicated by the arrow over a uide roll 14, thence down into the liquid in t e tank 15 and around the roll therein,

and thence up and between s ueezing rolls 1 is 18,19, and

down to a suitable support for reeeiving it. Certain of the rolls, as, for instance, the rolls 16, to 19, inclusive, may be positively driven inany well known or approved manner, the roll mounted within the liquid in the tank and which forms -thesubj'eet of my present .in-

vention being rotated by the rope or chain of fabric which passes around it.

WhatI elai1 1is:. k l 1. A roll for eireulating liquidin which it is immersed, said roll comprising longitudinal blades arranged along its ,periphery, one blade being inclined toward and extended in 'wardly within the roll to a greater extent and inelined toward oneanother for indueing a eurrent of liquid between them as the roll is rotated.

3. A liquid eireulating roll adapted to be immersed in the liquid and comprising blades extending longitudinally alon its periphery and inwardly therefrom and ilirniing a Sufiport for the material tobe earried'by the re the said blades being of'diflerent depths and inclined toward each other for inducing a current of liquid between the bladesas the roll is rotated.

4. A liquideireulatin roll adapted to be immersed in the li Hit? and .comprising a skeleton peripheryv orined of longitudinal blades arranged in pairs, the members of a pair being of diil'erent depths, rims for supporting the blades and hubseonneeted by spokes with the rims, the said spokes being set laterally at an angle to form in effect a serew propeller for inducing a eurrent of liquid through the end into the interior of the roll.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this 24th day oi Junel907.
