The invention has for its object the provision of a novel and improved type of wringer employ- 5 ing a pneumatic roll in co-operation with a roll so grooved as to tend to distribute equally between the rolls a fabric material fed therethrough. The invention consists also in the pro vision of n ovel means'for mounting and inflat- [0 ing the pneumatic roll and for renewing the roll surface and for carrying off the water squeezed by the rolls from the material therethrough.

In the drawing: i F'igure l is a view partially in front elevation and partially in section showing a wringer device embodying the invention.

Figure 2 is a view on an enlarged scale showing in detail a fragmentary end elevation of my improved device, the trough being partially broken away to a section exposing the bearing block for the yielding roll.

Figure 3 is a fragmentary detail view on an enlarged scale showing principally in section, the

associated ends of the respective rolls. portions of the rolls being illustrated in elevation.

- Figure 4is a fragmentary detail view showing a replaceable cover or tread for the pneumatic roll.

Like parts are identied by the same reference -characters throughout the several views.

As a part of my improved wringer support I provide a tubular standard at 5 having supporting legs 5 which are preferably adjustable as clearly illustrated in Fig. l, and which preferably provide space within which a pail 1 is receivable beneath the tubular standard 5 to receive water expressed by the wringer. The standard may be provided with bracket arms I4 to support other Peil-S At its top the standard I carries a trough 3 which drains through the standard 5 to the pail 1 and serves as a part of the wringer frame. 'Ihe trough I has a rigid sleeve 3 projecting into the standard to serve as a fulcrum upon which the wringer may be swung bodily about the standard.

At each end of the trough 8 there are U-shaped guide members Il and Il respectively, the latter having a circular loop I2 formed in its upper so end of suillcient diameter to pass the pneumatic roll hereinafter to be described, to facilitate the assembly and'disassembly of the parts.

Slidable in the respective guides Il and Il are the bearing blocks I5 and i5 carrying the trun- II nion shaft l1 of the lower roll I3. This rollmay comprise a tube, preferably metallic, carried by a spider I3 at its end from the trunnion shaft i1. The tube has its periphery provided with intersecting helical grooves 20 and 2i of opposite pitch, which serve toieed the material axially of the 5 rolls in the course of its progress therethrough and to distribute the material between the rolls. At each point of intersection of the grooves 20 and 2l, and elsewhere if desired, there are holes 22 which open through the tubular roll I8 to the 10 K interior thereof to carry away water which may have been expressed from the material passing between the rolls and may be confined on the surface without opportunity of escape. The grooves and holes together provide,means for preventing 15 any such water from accumulating.

The bearing blocks 23 and 24 are removably restrained by bolts 25 and 26 from yielding upwardly in the guides III and il. The shaft 21 which extends through these bearing blocks is 20 tubular and'is formed at 23 to provide a crank having a pump barrel 29 as a handle. The usual plunger 30 is mounted in the pump barrel and reciprocable therein to force air under pressure through the tubular crank 23 and shaft 21. For 25 emergencies the other end of the tubular shaft 21 may be provided with a conventional valve stem 3l and cap 32 for connection of an ordinary tire pump to produce the required pressure. When the bolts 25 and 26 are withdrawn the bearing 30 blocks 23 and 24 may be raised toward the top of their, respective guides III and i I, and the shaft 21 may be withdrawn from the bearing block 23. 'I'he block 24 and the wringer roll assembly on shaft 21 is bodily witndrawabie through the loop 35 Shaft`21 carries at each end a pair of heads such as those shown in Fig. 3. The inner head 33 provides the roll hub and is pinned to shaft 21. Screwed thereto is the clamping outer head 34 which holds the end of the tube 35 of rubber or the like, which comprises the pneumatic roll. I preferably employ an inner solid roll at 36 which prevents the pneumatic tube 35 from being 45 unduly collapsed. There are ducts 31 aioiding communication from the interior of the hollow shaft 21 through the solid roll 36 to the interior of the tube 35, whereby the inner surface of the tube may be subjected to air pressure.

If the tube 35 becomes worn it may be replaced readily by loosening the clamping members 34 and removing the upper roll as above described. It may, however, also be covered by a supplemental tube 34 drawn over the tube 35 as shown 55 in Fig. 4 to provide a new surface with the metallic roll Il.,

It is to be noted that the compression springs 39 act upwardly on the trunnion blocks I5 and I6 of the lower roll only. The upper blocks 23 and 24 are held stationary against the bolts 25 and 26, and the yielding of the upper roll surface is and to co-act fentirely pneumatic.

tribute the material to avoid unequal thickness and at the same time they serve to carry off expressed water from the bite of the rolls, either allowing such water to run about roll IB to a point where it can fall by gravity into trough 8, or allowing such water to pass through the holes 22 to the interior of the roll I8 and through the open end thereof into trough 8. In either case the water is discharged through the rotatable sleeve 9 into the tubular column 5 and thence to the pail 1.

I claim:

1. In a Wringer roll, the combination with supporting means,` of a solid inner roll carried by said means, a iiexible tubular sleeve carried by said means in sufficiently closely spaced relation to said inner roll to comprise an auxiliary support for said sleeve eiective following a moderate distortion thereon, a supporting shaft extending through said inner roll, and means for infiating the space between said inner roll and sleeve.

2. In a wringer roll, the combination with a supporting shaft, of an inner mounted head, a flexible tubular sleeve having its end engaged over said head, a cup-shaped clamping outer head holding the end of said sleeve in clamped engagement with said inner head, and means connecting said heads and adjustable axially of said shaft for applying clamping pressure to said sleeve.

3. In a wringer, the combination with a solid cylindrical support, of a flexible tubular sleeve suiiiciently larger in diameter than the support to be normally out of contact therewith except when distorted under pressure, said sleeve being mounted over said support in sufliciently closely spaced relation to receive auxiliary support therefrom upon distortion of said sleeve, means hermetically connecting said sleeve with said support, means for inflating said sleeve, means mounting said support for rotation with said sleeve, a eoacting roll with which said sleeve is engageable, and a frame in which said coacting roll and mounting means are disposed in operative relation. Y,

4. In a wringer, the combination with a solid cylindrical support, of a flexible tubular sleeve sufficiently larger in diameter than the support to be normally out of contact therewith except when distorted under pressure, said sleeve being mounted over said support in suiiiciently closely spaced relation to receive auxiliary support therefrom upon distortion of said sleeve, means hermetically connecting said sleeve, with said support, means for inflating said sleeve, mean's mounting said support for rotation with said sleeve, a coacting roll with which said sleeve is engageable, and a frame in'which said coacting roll and mounting means are disposed in operative relation, said frame comprising members with which said mounting means is detachably connected for the bodily withdrawal of said support from said frame.

5. `In a wringer, the combination with a rotatable support comprising an inner head, of a exible tubular sleeve having its end engaged over the periphery of the head, a cup-shaped clamping member having a face closely adjacent the end of said head and having a peripheral wall engaged over the end of said sleeve for holding said sleeve to said head, and screw threaded means connecting the face of said cup-shaped clamping member to the end of said head for maintaining the endY of said sleeve under clamping pressure.
