WILLIAM C. W'IIITCOM'R, OE CHICAGO, ILLINOIS, AssIGNOR To GEORGE D'. WHITCOMB COMPANY, A CORPORATION OF ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 742,941, dated November 3, 1903. Application filed February 28,1902. Serial No. 96,110. (No model.)

To au w/tom it may concern,.-

Be it known that LWILLIAM C.WHITCOMB, a citizen of the United States, and a resident of Chicago, county of Cook,'and State of Illinois, have invented certain new and useful Improvements in Knitting-Machines,of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to take-up rolls employed with knitting-machines, and has particular reference to such as are provided with yielding radial projections or studs enabling them to firmly grasp the fabric issuing from the knitting mechanism to insure the proper tension thereon.

In practice it has been found that while rolls of the above type properly perform their function in taking up cotton and like fabrics they are not entirely satisfactory in dealing with woolen and similar rough materials, owing to the tendency of the villous or hairy substance on the surface of the cloth to become entangled in the projections, causing the material to adhere to the rolls and to be Wound about the same, thereby interfering with the operation of the machine.

The invention has for its object to obviate this fault; and to this end it consists in providing each roll with a sleeve or shield of some suitable material, as the fabric produced by the machine, whereby direct contact of the fabric being knitted with the projections is avoided;

Reference is to be had to the accompanying drawings, in which- Figure l illustratesa portion of a take-up roll, partly in section and broken away, showing the shield or covering thereon; and Fig. 2 is a transverse section of a pair of take-up rolls in operative relation.

I have shown in Fig. l of the drawings a take-up roll consisting of a core 10, having a covering ll,of rubber,sleeved upon the same, the said covering being provided with radial,

preferably yielding projections, or studs 12. l

In Fig. 2 a pair .of such rolls in operative position is shown, the fabric passing between the same being indicated at 13. In order to maintain the proper tension on the product issuing from the knitting mechanism, it is necessary that the rolls be held closely together, so that the projections thereon may firmly though yieldingly grasp the fabric. As thus operating, however, it has been found that the nap of fabrics of a woolly nature becomes entangled in the projections, this sometimes resulting in winding the fabric about the rolls and necessitating the stopping of the machine to remove the same. To pre vent this, I provide a covering 14 of some suitable material, such as the fabric produced by the machine, to which the material passing between the rolls will not adhere and which is sleeved over the projections of the rolls, as shown, thereby preventing direct Contact of the knitted fabric with the projections.

The take-up rolls of the character vherein referred tog-that is to say, such as are provided with yielding projections or studspossess certain advantages over the ordinary Vsmooth rolls in that owing to their formation they are enabled to secure a firm yet yielding` hold on the material passing between them. Under my invention these advantages are rea tained, the ordinary action of the rolls being the same, while the objections thereto are overcome.

I do not confine myself to the employment 'of the fabric shield or cover with the roll ting-machines having its face provided with yielding projections, and a pliable sleeve carried by and resting against the projections.

2. In combination, a take-up roll for knitting-machines having its face provided with ting-machines comprisinga body having elasexible projections, and a pliable sleeve cartic radial projections, and a shield of fabric 1o ried by the said projections. covering such projections.
