UDOLPHO H. ODELL, OF DAYTON, OHIO.
CRUSHlNG-ROLL.
SPECIFICATION forming part of Letters Patent No. 260,226, dated June 27, 1882.
Application filed March 16, 1852.
To all whom it may concern:
Be it known that I, UDOLPHO H. ODELL, a citizen of the United States, and a resident of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Crushing-Rolls, of which the following is a specification.
This invention relates to an improvement in rolls for roller-mills.
My object is to so make the breaking-ribs on the faces of the rolls that the degerminatin g and gradual reduction process will be accomplished in a perfect manner. 1 make each corrugation or rib with a plane beveled surface on one side and a concave surface on the opposite side, and the front or outer edges of the ribs with a plane face curved on the circle of the rolls.
Another object of my invention is to drive such rolls by belting mechanism which is so arranged that by transferring the drivingpulleys to the opposite side of the machine the speed of said rolls may be reversed, so as to run them either as cutting or crushing rolls, as desired.
In the accompanying draWings,Figure lrepresents a segmental view, in cross-section, of a pair of my crushing-rollers. Fig. 2 is a similar view, showing cutting-ribs of size for a second break. Fig. 3 is a similar view of a still smaller corrugation. Figs. at, 5, 6, 7, 8,9, 10, 11, and 12 show old forms of corrugations. Fig. 13, Sheet 2, is an end elevation of portion of aroller-mill embodying my improvement, and showing the manner of driving the fastspeeded rollers. Fig. 14 is a view of the beltin g mechanism for the slow-speeded rollers on the opposite side from the view shown in Fig. 13. Fig. 15 is a plan view of a pair ofmy rollers.
Myimproved rollers are represented on Sheet 2 as set in a machine constructed similar to the one shown in Letters PatentNo. 250,954, grantcd me December 13, 1881. The form of ribs on the rollers shown in Figs. 1, 2, and 3 l have found by experience to be substantially better than the older forms shown in the remaining figures on Sheet 1. I form the gran ulating sides of the ribs of each roll on a parallel line with each other, thus forming acute angles to theradius of the roll, as indicated by the line a Z), Fig. 1.
(No model.)
This angle is preferably about thirty degrees from the radius of the rolls. The opposite side of each rib is concave, as at 2, and the face of the rib is wide and plain, as at 3. The proper proportions for these lines will be to have the face 3 one-half the length of the bevel side, and the length between the ribs on the line of the face of the teeth twice the length of the beveled sides of the ribs. This form of rib is important, as the grains are split without chopping the bran or breaking the germ in the act of reducing by a series of passes through rolls having gradually-reduced sizes of ribs. Again, by making one side of the rib of concave form, having a wide concave opening in the bottom, the grooves or channels clean much better than in any of the old forms of corrugations, and at the same time the grain is split and granulated better and with a less amount of break-flour in each of the gradual reductions, removing the bran in a more clean and better manner. The bevel and concave channels hold the fine material and carry itpast the point of contact with the adjacent roll without subjecting it to a further reduction while the coarse portions are being reduced. The wide faces of the rolls furnish better wearingsurfaces than those where the ribs are pointed, and the faces of the ribs are on a true circle, and are not destroyed by the corrugating-tool, which is the case when the teeth are pointed. These rolls may be made non cutting or crushing by reversing the speed of the rollers, which is accomplished by transferring the pulleys on the shafts of the slowspecded rollers to the shafts of the fast-speeded rollers. It will be advantageous in this case to round off the back corners of the cutting-faces of the ribs.
A indicates the frame of a machine on which are mounted my improved rollers.
B 13 0 0 indicate the drivin g-pulleys mounted on the fast-speeded rollers, and D D the driving-pulleys mounted on the shafts of the slow-speeded rollers.
G indicates the tightener-pulleys, and G the driving-pulley on the main shaft.
F indicates the belt driving the fast-speed ed rollers, and E the belt driving the slowspeeded rollers. I
When it is desired to reverse the speed of the two sets of rollers so as to run them as noncutting rollers, pulleys O are interchanged with pulleys D, and my improved rollers will operate with most of the advantages liereinbee fore named, accruing from the peculiar shape of the outer faces. What I claim isl 1. In a machine for grinding grain the combination of two (so-operating rolls having the series ofgranulating-ribs, each rib beingforlned with a plain outer face, and on one side with the plane bevel 1, arranged at an angle to the radius of the roll, and on the opposite side with the concave 2, substantially asand for the purpose shown and described.
2. In a machinefor grinding grain, the combination of two cooperating rolls having a series of granulatingribs, one side ofeach rib nesses.
