CHRISTIAN SIGMUND, OF GEORGETOVVN, DISTRICT OF COLUMBIA.
IMPROVEMENT IN MIDDLINGS-PURIFIERS.
Specication forming part of Letters Patent No. 146,485, dated January 13, 1874; application filed August 13, 1873.
To all whom it may concern:
De it known that I, CHRISTIAN SiGMUND, of Georgetown, in the county of Washington and District of Columbia, have invented a new and valuable Improvement in Middlings-Puriers and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,
in combination With a reciprocating air trunk or chest carrying a series of perforated pipes, which are arranged beneath the said screen, and which receive air from Without the chest of the separator, and direct it in jets through the screen or cloth, so as to operate, in conjunction with the suction or exhausting fan, upon the light substances mixed With the flour, and
carry them off into a receptacle suitably adapted to the purpose, as Will be hereinafter explained. The following description of my invention will enable others skilled in the art to understand it.
In the accompanying drawings, C represents `the chest of separator, the bottom of which is composed of two inclined boards, which are directed into a receiver, N, through which receiver the diii'erent grades of flour fall, and
are collected in the usual Well-known manner.
`.A represents the hopper, at the bottom of which is a roller that receives its rotation from the main driving -shaft K through belts and pulleys. From the hopper the ilour falls upon the upper end of the cloth b, which is applied to the screening-frame B, which frame receives a reciprocating shaking motion from aneccentric, c', acting through the medium of a connecting-rod, c. The eccentric c 1s on a hori- `zontal transverse shaft, which receives rotation from the main shaft K by means of belts and pulleys. Below the upper extremity of the screen B farthest from the hopper A is a space, f, through which the tailings,` fall, and are received below into a proper chamber.
Above the screen B, and on top of the chest y its case from the interior of the chest C, and" discharged from its opening, as indicated by the direction of the arrows in Fig. 2. Beneath the bolting-screen I arrange a series of pipes, el, which are perforated on top, as shown in Fig. 1, and which communicate with a central air-trunk, D. This trunk, from which pipes el extend laterally, slides upon and is closed at its bottom by a bottom piece, D', extending longitudinally from one end" to the other of the chest C, as shown in Fig. 2. The trunk D slides practically air-tight upon its bottom D', and it receives its endwise motion from a crank-sl1aft,J, and connecting-rod j. The bottom piece D is perforated vertically, and to these perforations the upper ends of air-induction pipes e are attached, the lower ends of which pipes penetrate the inclined boards constituting the bottom of the separator-chest, as shown in Fig. 1. i
The perforated jet-pipes c1 extend out laterally from the common airreceiving trunk D; but I do not conne myself to any definite arrangement of the jet-pipes, as they may be arranged diagonally, 'or in any other suitable` manner. They may be cylindrical pipes, as shown, or they may be ilat, and of any desired Width, with several rows of perforations through their upper sides. In practice, I prefer to make the jet-pipes cylindrical, and to employ, at the entering ends of the inlet-pipes c, valves c2, for regulating the induction of air .or cutting off the same.
It Will be seen from the description which I have above given that I exhaust from above the screen or boltingcloth, and that below this screen I introduce air from without, through perforated pipes, all which communicate with a trunk, D, to which a reciprocating motion is given, independently of the motion given to the screen. By these means the light substances are separated from the our as it is moved over the screen by the shaking motion given thereto, and such substances are drawn upward by the exhausting fan, and forced from below upward by the intlowing jets of air, induced by said fan, into the fan-case, and are from thence expelled out of the machine.
The box G is intended to afford a free intermediate space for the light flying substances ontheir way into the fan-case, so that all of such substances which are drawn through the What I claim as my invention, and desire to secure by Letters `Patent, is
1. A reciprocating air trunk or chest carrying perforated air-injecting pipes, in combinaa CHRISTIAN SIGMUND.
