MILLER T. G-ItEENLEAF, OF QUINGY, ILLINOIS.
IMPROVEMENT IN WiiDDLlNGS-PURIFIERS.
Specilieation'forining part of Letters Patent No. 147,388, dated February 10, 1874; application filed i November 19, 1873.
To alt Awhom fit may concern:
Be it known that I, MILLER T. GREENLEAF, of Quincy, in the county of Adams and in the State of Illinois, have invented certain new and useful Improvements in Flour-Dustin g and Middlings-Purifying Machine; and do hereby declare that the following is a full, clear, and exa-et description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.
My invention relates to the class of machines known as flour-clusters or middlings-purifiers; and it consists in the construction and arrangement of the same, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation, Fig. 2 an end view, and Fig. 3 a longitudinal vertical section, of my machine. Fig. 4 is a partial section of one end of the machine. Fig. 5 is a section through the fan, and Fig. 6 is a perspective view of one of the riddle-hangers.
A represents the frame of my machine, constructed in any suitable manner, to contain the various working parts. In one end of the frame A is formed the hopper B; and at the bottom of said hopper is an oscillating flexible feed valve` or bar, G,.for the purpose of self adjusting and regulating the feed evenly into the disintegrator below. The valve or bar O is attached to a shaft, a, which has its bearings in the ends oftwo arms, E E, pivoted, one upon each side, on the outside of the frame A. Through the inner end of each arm E passes a rod, b, on which, above the arm, is placed a spiral spring, d, and a nut, c, is screwed upon the upper end of the rod down upon and against the spring. By this means the feed valve or bar C may be adjusted up and down,and also `rendered iiexible by the springs on top of the inner ends of the arms E E, the tension of the springs being regulated by the nuts e e. Upon one end of the feed-shaft c is formed or attached an arm, f, the outer end of which is slotted, and passed over a crank-pin, z', projecting from a disk or wheel, 71, placed upon Ithe end of a revolving shaft, D. By this means the shaft a and valve G obtain an oscillating motion. The disintegrator is composed of a revolving shaft, lo, with a head, Gr, at cach end, said heads being connected by rods or beaters m m, and the whole inclosed in a concave or jacket,
H. This is used for the purpose of whipping v or beating the dust and flour from the middlings, and then throwing them out into a current of ascending air, thus making a perfect separation of the dust and middlings while in suspension. The middlings iinally fall on the gathering-boards I, and slide onto the riddles J J, and there grading the iner from the coarser, and separating the middlings from the bran. The iiour and dust are carried upward through the chamber K, forward through the flue K1, and down through a closed passageway, K2, where, near the lower end of the passage, is an abrupt turn upward to the fanchamber L. At this point the heavier portion of the flour and dust passes down and falls in a trap or valve, M, and, when the load is heavy enough, the valve opens, and it may pass into spouts that lead it away. The light fuzzy dust is 'carried on up to the fa-nchamber L, and passed through the fan into the dust-room. The top of the fan-chamber L is provided with a large valve, N, hung so as to open inward, and provided with an arm, u, upon which is a movable weight, 0. This weight may be moved back and forth on the arm, so as to hold the valve against its seat to any desired pressure. This arrangement makes it a self-acting governor, allowing at all times the same amount of air to pass through the disintegrator. The valve N is provided, on its upper side, with two projecting wings, having" small downward-projecting pins y at their ends, which rest in recessed seats z on top of the mill, so that the valve can at any time be removed, when desired. At the highest point between the disintegrator and the fan-chamber in the ilue or passage K1 is a valve, P, opening from the air-passage into the chamber over the riddles, This valve is provided with a quadrant, r, and screw s, for the purpose of adjusting the currents of air passing through the chamber. The riddles J J are arranged as shown-one top and one bottom, horizontal sieves, and two intermediate inclined ones, all in a frame, R,
which is moved back and forth by means of a crank-shaft, t, and pitman o. The riddle-frame lt is suspended by means of hangers w w, passing through loops on the under side of the riddle-frame. The ends of the hangers are provided with screw-threads, and passed each through a sleeve or tube, x, and a nut, y, screwed on the end of the hanger above the tube. The tube x is provided with a pin or arm, z, which is inserted in a loop, a', formed upon a slotted plate, b', and this plate adjusted upon the main frame A. By this means the riddle-frame may be adjusted in any desired llltlllll.
lhe n'iiddlings, bein g poured into the hopper B, are fed by the adjustable rocking valve C to the disintegrator, by which the fine fuzz, dirt, Src., is beaten from the middlings; and the middlings pass down onto the gatheringboards I to the riddles J, Where they are separated from the bran and graded in different qualities. After leaving the disintegrator, the fuzz, dirt, 85e., is carried up by the air-current caused by the suction-fan through the passages K, K1, and K2, in the latter of which the heavier particles of these substances fall down and out through the trap or valve M, while the lighter substances pass with the air-current through the fan-ease L, and out of the machine. The force of the air-current is adjusted or regu lated by means of the valve I), and, when so adjusted, is maintained uniform by means of the governor-valve N.
Having thus fully described my invention,
what I claim as new, and desire to secure by Letters Patent, is-
1. The combination of the feed-valve C, shaft a, lslotted crank f, pin 1'., and revolving disk h,
substantially as and for the purposes herein set forth.
2. The combination of the feed-valve C, shaft a, pivoted arms E, rods b, springs d, and nuts c, all constructed substantially as and for the purposes herein set forth.
3. The combination, in a middlings-puriiier, of the chambers K K1K2, suction-fan and chamber L, disintegrator G, riddles J J, and gathering-boards I I, all constructed and arranged to operate in the manner substantially as and for the purposes herein set forth.
4. The combination, in a middlings-purer, of the chambers K K1K2,suction-fan and chamber L, adjustable valve l?, feed-valve C, disintegrator G L m, gathering-boards I I, and the riddles J J, substantially as and for the purposes herein set forth.
5. rlhe removable valve N, provided with Wings w', pins y', arm n, and Weight O, all substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this llth day of October, 1873.
