IMPROVEMENT IN MIDDLINGS SEPARATORS.
Specification forming part of Letters Patent No. 120,706, dated November 7, 1871.
To all whom it may concern: 1
Be it known that we, JOHN B. BRENNAN and WILLIAM TUCKER, of Paris, in the county of Edgar and in the State of Illinois, have invented an Improved Middlings Separator; and do hereby declare that the following description, taken in connection with the accompanying drawing hereinafter referred to, forms a full and exact specification of the same, wherein we have set forth the nature and principles of our said improvement by which our invention may be dis tinguished from others of a similar class, together with such parts as we claim and desire to secure by Letters Patent.
Our invention relates to that class of fanningmills which is made use of for the purpose OI separating middlings or the coarse part of flour; and the nature thereof consists in certain improvements in the details of the construction of the same, hereinafter shown and described.
In the accompanying drawing, which illustrates our invention and forms part of the specification thereof, Figure 1.is a perspective view. Fig. 2 is a longitudinal vertical section. Fig. 3 is a rear elevation.
The construction, operation, and relative ar rangement of the component parts of our invention are as follows: In the front of the machine is the suction-fan A, so arranged as to draw the air fromthe rear. Just back of the said fan is the slide-valve B, which regulates the draft. In the rear end of the machine are arranged the three sieves O D E within the frame F, which is connected by means of the connecting-rod H with an eccentric upon the transverse shaft I. The rotation of the said shaft causes the frame containing the sieves to reciprocate upon the springs K. The said sieves are inclined downward, and formed partially of solid pieces L and partially of bolting-cloth M, so that after the middlings pass through one sieve they are carried back by the inclined pieces N in such a manner as to pass through the others until they fall in the hopper under the frame, from whence they pass out of the machine. The object of forming part of the said sieves of solid pieces is to allow the bran or light stuff to shake to the top after falling and pass down the incline more rapidly than the remaining heavier portion, so that when it comes to the open part, where there is a current of air drawn by the fan, it is taken up and carried over the end of the sieve, While the heavy middlings fall through and pass to the next sieve. Under each sieve, and hinged to the frame thereof, are the valves 0, so arranged as to regulate the current of air passing through the same and carrying the light stuff out through the fan and into a hopper placed in front of the sieve. On the top of the machine is the upper sieve I which is attached to the lower frame by the springs R, and operated by means of the connecting-rod, to which vibratory motion is im parted by the shaft. The bran and middlings are fed in at the upper end of the sieve P, and as they pass downward the fine middlings fall through the fine screen S upon the bottom T and are carried down to the lower end thereof, where they are discharged through a spout and carried off, while the coarse middlings and bran pass down to the coarse screen U, fall on the carrierboard V, and are fed into the hopper W on the top of the machine, where they drop upon the upper seive before described.
Having described our invention, we claim- The combination and arrangement of the sieve 1?, frame F, valves 0, inclined chutes N, and sieves G D E, constructed with the perforated and unperforated parts M and L, substantially as shown and described, and for the purpose set forth.
In testimony that we claim the foregoing we have hereunto set our hands this 6th day of June, 1871.
JOHN B. BRENNAN. WILLIAM TUCKER.
