FEED MECHANISM FOR ROLtER-MILLS'.

' SPECIFICATION forming part of Beissued Letters Patent No. 10,979, dated J anuary 8,1889.

Original l l'o. 280,184 dated June 26, 1883. Application for reissue filed June 13, 1885. Serial No. 168,559.

To all whom it may concern:

' Be it known that I, WILLIAM M. J EWELL, a citizen 9f the United States, residing at Pine,

in the county of Jefferson and State of 0010-- rado, formerly a resident of Denver, Colorado, have invented certain new and useful Improvements in Feed Mechanisms for Roller-Mills; and I do hereby declare the following to be a full, clear, and exact description of theinvention, that will enable others skilled in the art to which it appertains to make and use the same, reference, being had to theac'companying-drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has for its object the assurance of a. steady and even feed and distribution of grain or middlings to the rollers of that class of grain-reduction mills of which the Gray patents are examples; and the invention consists, to this end, in the construction, combination, and arrangement of parts,

as hereinafter specified and claimed.

In the accompanying drawings, inthe several figures of which like parts are similarly designated, Figure 1 is a side elevation of my' feed applied to a Gray roller-mill, the rollers being indicated by dotted lines. Fig. 2 is a transverse section of the feed from left to right of.- Fig. 1. Fig. 3 is a longitudinal-section of the feed; and Fig. 4 is a sectional detail, enlarged, of the adjustable riffle.

A is the feed-case, and B the vibrating or shaking frame suspended therein upon straps h h ofspring-steel.

O is the hopper, which for a double machine has a centralpartition with a movable gate, a, to divide the incoming grain or middlin gs into two streams, and which gate may be thrown across one'or the'other of the mouths of the two compartments of the hopper to divert the grain or middlings to but a single pair of roll ers, as may be desired, the normal position of this valve for a double machine using both pairs of rollers being indicated in Fig. 2.

D is the feed-spout'.

The discharge end of the hopper is,pro-.

"ided withmovable gates o to aid in directing and governing the discharge, and beneath the hopper and in line with its partition is a vertical partition, f, in the shaker, lengthwise 1. The combination,

thereof. Pivoted lengthwise of the shaker and normally at opposite inclines I from the bottom of the hopper are shelves or chutes c 0, their inclination being, variable by thumb- 5 5 nuts on bolts and slotted segments 9 g, through which said bolts extend, the variation in the inclination being governed by the condition of the grain. These shelves have at their outer ends, longitudinally thereof, ridges'or 6o ribs 2' to prevent centering of the grain thereon. The grain falls from shelves 0 c on shelves 1) b, beneath said shelves b I) being pivoted also and inclined, but in a reverse direction 3 with relation. to the sh elves c c, and said shelves 6 5 b b are similarly adjustable with, bolts, thumbnuts, and slotted segments g 9. At the bottom of the shaker are placed the inclined riflles dd the same being plates or boards having serrated surfaces. v

Adjustable riflles e are arranged at the outer ends of the riffle-boards d d. The adjustability of these riflies is secured by bolts 6' passing from the rifile-board up through slots in the riffies and provided with suitable retaining or cramping nuts andwashers or like devices bearing upon the upper faces of the said riffles The boards d d are inclined toward discharge-spoutspp. These spouts pp are provided with equalizing-shelves Z-m, in-

clined at different angles from opposite walls of the spouts. The spouts p 10 open over the meeting faces ofthe subjacent pairs of reduction-rolls.

L is a shaft suitably supported upon the frame and banded by belt n over pulley N to the shaft of one of the fast rollers M, and this shaft L is eccentrically connected bya pitman or link, It, with shaker B, so as to impart thereto a' shaking or vibratory motion, and thereby positively cause the descent of the grain or middlings from one shelf to another through the series 0 1) cl 1 m to the rollers. The riffle-shelves d d insurethe breaking up of lumpy middlings.

Doors d a are provided inthe feeder to From the above description of my invention its operation. is obvious and the advanfage apparent.

What I claim is.

with the rollers of a roller-iiiill, of the vibrating inclined rifiieboard (I, having" a corrugated or serrated upper'surface, an an end rifile, e, which is adjustable back a d forth, and the spout p, hav-. ing the oppositely-inclined overlapping equalizing-shelves land m, projecting from its opposite sides or walls, substantially as described.

2. The combination, with the casing A and the hopper C, of the frame B, suspended within said casing and provided with a series of oppositely-inclined adjustable distributingshelves, the eccentric-shaft L,"and the rod or pitman k, for imparting vibratory or shaking motion to said frame, and the rollers of a roller-mill, substantially as described,

3. The combination of the casing, the hopper, the frame suspended beneath said hopper and provided with a series of oppositely-inclined adjustable distributing-sh elves, the upper shelf of the series having an anti-center.

i'ng ridge orrib at its outer end, the eccentricshaft and the rod or pitman for vibrating said frame, and'the rollers of a roller-mill, substantially as described.

4. The combination of the grain-reducing rollers, the hopper, the frame suspended be tween said rollers and hopper, means to shake or vibrate said frame, and the inclined riiileboards d, provided with the adjustable end rifiles, e, substantially as described.

5. The combination, with the casing Aand the hopper C, of the vibrating frame B, provided with two oppositely-inclined distributiug-shelves, c and b, and the spout 1), having the oppositely-inclined overlapping equalizing-shelves l and m, which project from its sides or walls, substantially as described.

6. The combination, with .the rollers of a roller-mill, of two oppositely-inclined shaking distributing-shelves, c and b, the outwardly and downwardly inclined riflle-board d, having a corrugated or serrated upper surface, and the spout p, having the oppositely-inclined overlapping stationary equalizing-shelves l and m projecting from its sides or walls, substantially as described.

7. Thecombination of the hopper C, the

casing A, the vibrating frame B, suspended therein and provided with the downwardly and outwardly inclined adjustable shelf 0,

-with the downwardly and inwardly inclined adjustable shelf b, and with the downwardly and outwardly inclined rifile-board d, having a serrated upper surface, and the spout p; having the stationary oppositelyinclined overlapping equalizing-shelves l and m, substantially as described.

8. The combination of a casing, a hopper having a swinging gate at the lower edge of its front wall, two oppositely-inclined vibrat ing distributingshelves, an outwardly and downwardly inclined riffle-board having a corrugated or serrated upper surface, and an adjustable rifile at its outer end, substantially as described.

9. ,The combination, with a casing and a hopper, of an outwardly-inclined vibrating distributing shelf arranged closely to said hopper and 'provided at its outer end with an anti-centering ridge or rib, an inwardly-inclined vibrating distributing-shelf, a ritfleboard having a serrated upper surface, and devices for adjusting the plane of said shelves,

, substantially as described.

10. The combination, with the casing A and the hopper C, of the vibrating frame B, suspended beneath said hopper and provided with an outwardly-inclined shelf, 0, having a ridge or rib, z',with an inwardly-inclined shelf, b, and with an outwardly-inclined riffle-board, d, having a serrated upper surface and an adjustable end rifile, e, and means for vibrating said frame, substantially as described.

11. The combination of a casing, A, a hopper, 0, a vibrating frame, B, suspended beneath said hopper and provided with an adjustable outwardly-inclined shelf, 0, having a ridge or rib, 2', at its outer end, with an adjustable inwardly-inclined shelf, 1), and with an outwardly-inclined riffle-board, (I, having a serrated upper surface and an adjustable end riflie, e, and means for vibrating said frame, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM M. JElrVELL.
