To all whom it may concern:

Be it known that I, JOHN E. HUTZEN, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have made a certain new and useful Invention in Roll-Reducing Machines; and I declare the following to be a full, clear, and exact description of the same, such aswill enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a side view of the machine. Fig. 2 is a horizontal sectional view. Fig. 3 is a vertical longitudinal section. Fig.

4 is a horizontal section of the reducing roll.

Fig. 5 is a detail sectional view on the line 5-5, Fig. 1.

This invention has relation to roll machines designed chiefly for reducing cereals to filament form, and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the machine described, the channeled cutting rolls consist of removable thin cylinder-edged disks of larger and smaller diameter, compressed solidly together on their shafts from eye to perimeter by means of suitable bracing collars, such rolls working together so that each set of rolls gives ofi two sets of filaments, the material being prepared by the action of crushing rolls over the disk rolls. Each disk-roll is easily taken apart for repair, and when the disks are assembled on the roll shaft, they are designed to be solidly held together, and especially at their peripheral portions, because of their thin. character. The adjustment of the rolls toward and from each other is of positive character in either di- 7 reetion, and is so designed that after the adjustment as to the thickness of the filament, this size will be maintained evenly throughout its length. In the accompanying drawings, illustrating the invention, the letter a designates a hopper, in or below which is placed a pair of smooth steel feeding and crushing"- rolls 6, 6, designed to crush the-grain, after it has been put in proper condition for shredding,

by boiling or soaking. Scrapers c, are

an excellent purpose.

'03, represents framework, which is pro vided with bearings for the boxes 6, e, of the cutting rolls, and with such other bearings as may be required for the necessary parts of the mechanism.

9, g, designate parallel'steel shafts, which are the basis of the cutting rolls f, f; and

on these shafts are seated the roll bodies composed of annular steel disks h, andis, arranged in series in the following manner. The disks are circular, and are made of thin sheet steel, saw steel being easily available for the purpose. The thickness of steel preferred is about one thirty-second of an inch.

The disks are bored to provide proper openings whereby they are seated on the shaft, and the openings may be provided 'with seats for placing a key or feather to pre- Venttheir turning on the shaft. The disks employed are designed to be of two diameters, the sm ller disks 70, being about five inches in diameter, and the larger disks it, about five and one-eighth inches; the difference betweenthe diameters being about oneeighth of an inch more or less; These disks are arranged in an alternative manner on the shaft, so that a small disk is seated between two large disks, and its circumferential edge forms the bottom of a small channel whereof the parallel circumferential portions of the larger disks form the side walls, and the terminal rectangular cutting edges of which, because of the hardened character of the disk surface, are designed to serve Such channel is therefore circumferential, having a depth of about a sixteenth of an inch, more or less, and a width of about a thirty-second of an inch, more or less. The cutting disks and the fine channels between their circumferences are designed to operate upon the grain '10 gage a thread of the shaft;

In order to preventundue frict1on between the cutting edges of the cutting disks 7 where they are designed to intermesh, thin' first paper disks may be interposed between the large and small disks of the series.

The working ends of the teeth t, which engage the edges of the smaller disks teeth securely and in the bottoms of the channels, under of the roll, are designed to have a concave curvature corresponding to that of the disk circumference. The concave end of eachtooth therefore terminates in an acute edge of nearly the width of the channel, and is designed to do efficient work in the 'dis charge of the filament of material thereom. In order toprovide for exact adjustment of the cutt' g rolls, each journal bearing box 6, is provided with a boss (2', which is provided with a threaded aperture to. en-

This exact alinement is of the importance, because of the fineness or smallness of the elements of the rolls, which requires elimination of angular variation, so that the edges of all the larger disks shall exactly meet alongthe rolls, and in this way divide the cereal into filaments by'such meeting without intermeshing. Angular variation in the alinement of the rolls will precereal material,
