VVILLIAM- M. JEVVELL, OF DENVER, COLORADO? FEED MEGHANISM FORROLLER-MILLS.
SPECIFICATION forming part of Letters Patent No. 280,184, dated June 26, 1883.
Application filed April 5; 1883. No model.)
To (LZZ whom it may concern:
Be it known that I, WILLIAM M. J EWELL, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Feed Mechanism for R011- er-Mills, of which the following is a specifica eral 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. Fig. 4 is a transverse section of my feed for a single pair of rollers, and Fig. 5 is a isfectional detail, enlarged, of the adjustable r1 e.
A is the feed-case, and B the vibrating or shaking frame, suspended therein upon straps hit, of spring-steel.
C is thehopper, which, for a double machine, has a central partition, with a movable gate, a, to divide the incoming grain or middlings 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 rollers, 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. I
The discharge end of the hopper is provided with movable gates 0, 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 thereof. Pivoted lengthwise of the shaker, and normally at opposite inclines from the bottom of the hopper, areshelves or chutes c 0, their inclination being variable by thumb-nuts on bolts and slotted segments g g, through which said bolts extend, the variationin the inclination being governed by the condition of the grain. These shelves have at their outer ends, longitudinally thereof, ridges or ribs '1', to prevent centering of the grain thereon. The grain falls from shelves 0 c on shelves 1) Z) beneath, said shelves 1) I) being pivoted, and also inclined, but in a reverse direction with relation to the shelves 0 c, and said shelves 1) b are similarly adjustable with bolts, thumb-nuts, and slotted segments 9 9. At the bottom of the shaker are placed the inclined riflles d d, the same be ing plates or boards having serrated surfaces. Adjustable riffles e are arranged at the outer ends of the riffle-boards d cl. The adjustability of these riffles is secured by bolts 6 passing from the rifieboard up through slots in the riffles, and provided with suitable retaining or cramping nuts and washers or like devices bearing upon the upper faces of the said riffies. charge-spouts p 1). These spouts p p are provided with shelves 2 m, inclined at different an gles from opposite walls of the spouts. The spouts p p open over the meeting faces of the subjacent pairs of reduction-rolls.
L is a shaft suitably supported upon the frame, and banded by belt it over pulley N to the shaft of one of the fast rollers M, and this shaft L is eccentrically connected by a pitman or link, It, with the 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 b d Z we, to the rollers. The riflle-shelves (Z (Z insure the breaking up of lumpy middlings.
Doors at a are provided in the feeder to gain access thereinto.
The boards (Z d are inclined towarddis- In Fig. 4 I have shown my feed mechanism adapted to a machine having a single pair of rollers. In this feed I prefer to use, instead of gates 0, a gate or bottom, E, hinged at c to a cross-beam in the'shaker, and supported and held normally closed by an adjustable spring, j, so that as the superincumbent grain or middlings overcomes the spring the bottom E drops and permits the descent of the material; but as this gate or bottom will form the subjectmatter of a future application, its construction IOO and operation need not be herein further de tailed. In this form of feed the shelf 0 may be fixed and the board (Z provided with only the 1. The combination, with the grain-reduc tion rollers, of a hopper, a series of deflecting distributing-she]ves inclined in opposite directions from opposite sides of the machine, and means for imparting to said shelves a sh aking or vibratory movement, substantially as shown and described.
2. The case A and the frame B, suspended within the case A, and provided with a series of oppositely-inclined distributing-shelves, substantially as shown and described, combined with a shaft, L, rod 7;, and operating mechanism to impart a vibratory or shaking motion to said frame, and the hopper and rollers of a rollermill.
3. The combination, substantially as shown and described, of the grainreduction rollers, a hopper, a frame suspended beneath said hopper and over the rollers, means to shake or vibrate said frame, deflecting distributingshelves inclined in opposite directions from opposite sides of said frame, and anti-centering ridges or ribs on said shelves.
4. The combination, substantially as shown and described, of the grain-reduction rollers, a hopper, a frame suspended between the two,
means to shake or vibrate said frame, and inclined riflles (Z, provided with the adjustable end riffles, c. I
5. The combination, substantially as shown and described, or the grain-reduction rollers, a casing, a hopper, a frame suspended within said casing, between the rollers and hopper,
means to shake or vibrate said frame, shelves inclined in opposite directions from opposite sides of said frame, and discharge-sp outs having deflecting-shelves inclined in opposite directions from opposite sides thereof.
In testimony whereof I affix my signature in presence of two witnesses.
