T 0 all'whom it may concern: as often. An examination of such rolls which have been in continuous use for a period of nine months, 'ves no indication of wear. The increas lifevof the rolls greatlyreduces thenumber of'reserve rolls which must be carried in stock by a mill.

In the accompanying drawings, the numeral 2 designates the steel body of one form of drawing roll having the reduced central portion 3 upon "which rests the usual weight saddle, not shown. The enlarged end portions 4 of the roll are each provided with my improved covering, shown at 5. These coverings consist of sheets of artificial cork. I prefer -Be it known that I HERMAN F. Boson, a citizen of the United tates, residing at Millvale, Allegheny county, Pennsylvania, have invented a new and useful Improvement in the following is a full, clear, and exact description, reference being had to the accompan ing drawings, formingpart of this spec' cation, in whichigure 1 is a plan view of one form of roll embodying my invention.

y invention has relation to certain new and useful improvements in rolls of the character widely used in all textile spinning.

and drawing processes, and more particuthe win ing is completed, the rolls are thorprovided with a covering of leather secured oughly baked in an to the metal body of the roll over a cloth backing or lining, the latter'acting as a cushion to increase the resiliency of the coverin Other covering materials have been trie usually with but little succes, leather being now almost universally employed.

I have discovered that greatly superior rolls may be obtained by providing them with a covering consisting of artificial cork.

Natural cork has not proven satisfactory for this purpose, 11gpparently for the reason that it is not s ciently homogeneous in character and also because its surface soon becomes glazed to such an extent that it does not exert a roper frictional grip on A covering of artificial cork such as is provided by my invention provides an extremely oven at a' sultable baking renheit. The covered portions are then By making-the coverin s in laminated form in this manner, I not on y avoid the necessity for the use of any molding or clamping devices in applying the coverings to the rolls, but a superior covering is provided, as the laminated structure is less liable to give way in service.

It is important that the artificial cork used should be of the proper character and density. 1 have obtained excellent results from a mixture consisting{ of one hundred pounds of granulated cor of glycerin and-five pounds of gelatin. also add about six ounces of paraformaldeserviceable and durable roll having a wearing quality better than that of leather; which will work under less pressure than is required with leather covered rolls and which does not pick up fiber to'nearly as great an extent as the leather coverings. The coverings provided by my invention can be readily and easily applied and renewed, and possess the degree of resiliency and frictional qualities which are desirable for this work. Actual tests of m invention show eimproved coveringpick up less than one-half the quantity of fiber that is p'cked up'hy leather covered rolls and only have-to be cleared I sure are then subjected to baking operations such as are customarily employed in the ing blocks are then cut into strips of the desired width. and thickness.

twenty pounds hyde in dry powdered form for the purpose These manufacture of artificial cork. The result-.

temperature of say from 17 5 to 200 Fahturned or ground to the exact size desired.

It is also impprtant that the cork granules employed in the mixture shall neitherbe too coarse nor toofine. I prefer to employ cork granules none of which has a dimension greater than three thirty-seconds of an inch and which will pass through a screen having eleven meshes to the inch. Preferably,

' also, none of the particles should be finer layers of the coverin than No. 40 mesh. In practice, the bulk of the material is usually between sixteen and twentgeight mesh.

As store indicated, my invention is not limited for use 'in connection with the particular form of roll illustrated in the drawing, but is generally applicable to the forms of spinning and drawing rolls used in textileoperations.

I claim:

1. A roll having a covering of artificial cork wound in convolute layers; substantially as described. i

2. A roll having a covering of artificial cork wound in convolute layers, adjacent being cemented to each other, substantial y as descriM-a eases 3. A spinning and drawing roll having a covering of artificial corkin thin sheet form wound upon itself in convolute layers, substantially as described.

4. A spinning and drawing roll having a covering of artificial cork in thin sheet form wound upon itself in convolute layers, the adjacent layers bein cemented to each other on both surfaces, su stantially as described.

5. A spinni and drawing roll having a covering of art icial cork in thin sheet form wound upon itself in convolute layers, the
