ROLLER 'FOR IR ONING-MACHINE S.

SPECIFICATIQN forming part of Letters Patent No. 292,958, dated February 5, 1884, r Application filed February 17, 1883. (no model.)

To all whom it may concern..-

Be it known that I, HAMILTON E. SMITH,

a citizen of the United States, residing at New York, in the county and State of New York,

have invented a new and useful Improvement in Rollers for Ironing-Machines, of which the following is a specification.

This invention relates to the constrnctio of the rollers of ironing machines, and especially such rollers in which a series of disks of cloth or other fibrous material are strung on an axial shaft, with-interposed metallic washers, and compactly pressed together thereon by means of end heads.

My invention consists in arranging the fibrous disks in two alternating series having diflerent diameters, and napping the edges of the larger disks for the purpose of imparting to the roller a superior surface elasticity. The invention is illustrated in the accompanying drawings, in which- Figure 1 represents a roller constructed in accordance with my invention, the figure being partly in side view and partlyin section; Fig.2, a cross-section on the line in w of Fig. 1, and Figs. 3 and 4 detail views of parts.

Similar letters of reference indicate corresponding parts.

The roller B comprises an axial shaft, 0, on which are strung two series of disks, D D, of cloth or other fibrous material, suitably perforated, and on the opposite-ends of the shaft are arranged heads E E, whereby the disks are compactly pressed together thereon, the head E being fixed to the shaft,while the head E is movab1e,and is subjected to the action of a jam-nut, F, screwing on the shaft. Said disks D D alternate with each other, and the disks D are larger in diameter than the disks D, while they are napped or carded-on the edges, as by means of a revolving brush or comb, so that the roller obtains a soft and elastic surface, andat the same time possesses the required solidity, the effect of the nap being materially increased by its laxity, due to the spaces created by the alternating arrangement of the disks. Said napping of the disks D is performed after both series of disks have been properly put on the shaft, and when the disks are composed of a woven fabric it is preferred to place the disks so that the threads of each of the larger disks shall intersect the threads of the other or remaining disks of that series. The shaft 0 is cylindrical, and is pro vided with a longitudinal groove, 0,which receives in it a bit, 8, projecting inward from each of a series of metallic washers, H, interposed at intervals between the fibrous disks D D, so that these washers are fixed to the shaft and act on the disks with a tendency to prevent their rotation. heretofore been secured on the shaft by male ing the shaft and the hole in the washers square; but in that case the disks are liable to wear unevenly opposite to the corners of the shaft, and also to be cut by such corners,where,-, as by making the shaft round or cylindrical the disks are exposed to a uniform wear. Each of the washers H is provided with radial ribs 41, which, when the disks are compressed on the shaft, together with the washers, become embedded in the material composing the disks, and inasmuch as said ribs are directly opposed to the circular strain on the disks they render the washers very effective in operation.

What I claim as new, and desire to secure by Letters Patent, is

The combination, substantially as herein set forth, of the axial shaft, the two alternating series of fibrous disks on the shaft having dif ferent diameters, and the larger disks having the edges napped or carded, and the end heads of the shaft.
