Application filed September 23, 1927. SeriatNo. 221,586.

This invention relates to a squeeze roll for a washing machine for textile plants.

The principal objects of the invention are to provide a roll which can be taken to pieces in case of injury tothe journals and a new shaft inserted and used with the old roll or certain parts of it; to provide a con-. struction in which if there is a fault in the body of the cast metal roll only this part of it need be lost, and to provide means where'- by the roll can be made up ofsections and these sections secured to the shaft in a sim of-the liquor to the shaft from the outside of the roll will be prevented. Other objects and advantages of the invention will appear hereinafter.

Reference is to'be had to the accompanya ing drawings, in which Fig' 1 is a side view of a squeeze roll for a textile washing machine constructed in accordance with this invention 1 Fig. 2 is a central longitudinal sectional view of one end of the same on enlarged scale;

Fig-3 is asectionalview on the line 3-3 of Fig. 2; and

Fig. l is a sectional view on the line 44. of Fig. 2 showing the roll in end elevation. Certain types of washing machines used in the pre 'iaration of cloth forsale have been made; solid, either of cast iron or steel, and some have been made. with a wrought iron shaft with a body of iron cast to it. In

.these' types of rolls the journals frequently break and then they are beyond repair. The entire roll and shaft or journal have to be replaced by new ones. Also if a blow hole or cold shot occurs in the body of thesolid roll the entire roll will be a loss, except for scrap. I

In order-to avoid these difliculties and perniit a new shaftto be put in or new parts of the roll to be substituted, without discarding the entire roll, 1- form my roll on a shaft 10 of a series of discs 11. These discs or rings are made of cast iron or steel ai'id keyed to the wrought iron shaft. 7

Each 'end ring is heldin place by a small ring 12 made in halves which fit into a groove around the shaft. A larger ring 13 is fitted is secured by screws 14 or the like. This concurely holds the discs or rings 11 in place.

la r-a2 and, also prevents the liquor from getting inalong the shaft past the ring 12.

The discs 11 are all provided with a circular groove 15 cut in the face thereof, and a gasket- 16 of lead or fiber is placed in this groove and extends all the way arounld. This prevents the liquor from getting into the shaft and destroying the ring fit on the shaft. Of course, the rings 11 are pressed. together firmly before therings 12 and 13' are applied at the end. In this way the gaslret 16 in each space adequately fills it and prevents passage of liquor therethrough,

Furthermore, the rings 11 are cut away at 17 so that they will have their bearing surfaces near the circumference and thegaskets 16 are located midway betweenthe innerand outer circulnferences of the bearing part where they'receive a maximum pressure. V 5 In this type of roll'daina-ges can be easily repaired. If the journals should break, the rings can all be taken off and a newshaft furnished, using-the old rings or discs. If

constitutes an improvement on account of p the economy involved in its use.

Although I have illustrated and described 8t) i there is any defectin one ofthe rings or I only one form of the invention I am aware I of the factthat changes can be made therein without departing from the scope of the iiiv-entionfas expressedin the claim. Therefore. I do not wish to be liinitedtothe exact form shown, but what I do claim is As an article of manufacture, a squeeze roll con'iprisin'g a central shaft, a series of separate metal discs mounted thereon, each disk being cut away at its surface adjacent I to the next one for a distance from the shaft,

aiideach two adjacent discs fitting each other for a distance inside the circumference to form a beaitiiig surface, each disc having a circular groove midway between. the inner and outer edges of said bearing surface, and a softgasket filling said. groove all around for the purpose described.

In testimony whereof I have hereunto affixed my signature.
