To all whom it may concern:

Be it known that I, ABRAHAM N. WOLF, of Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Separators; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in separators for separating the dirt and germs from cracked wheat; and it consists in the arrangement and construction of parts, which will be more fully described and claimed hereinafter, whereby a simple and very eliicient machine is produced.

The object of my invention is to provide a machine by means of which the dirt and germs of the berries can be extracted from the crack ed wheat, and thus enable a better and liner grade of flour to be produced. l

Figures l and 2 are vertical sections of a machine embodying my invention, taken at right angles to each other.

A represents a suitable frame, in which tl e separator-frame A is rigidly secured. This frame A may either be of the shape here shown or any other that may be preferred. Connected with this frameA at one end is the passage M, through which the cracked wheat passes into the frame A as it leaves the rollers or other mechanism by which it has been cracked, for the purpose of separatingthe germs of the berries and dirt which is in the creases from the cracked portions of the berries or wheat which is to be used in making our. Inside of this frame A is placed the perforated stationary cylinder G, which may be made pear-shaped in cross-section, as here shown, or any other that may be preferred. This cylinder is open at its apex, so that the direct suction of the fan can be exerted upon the broken grain in the cylinder, and thus the light particles carried off without obstruction. The perfora` tions in this cylinder are just large enough to allow the germs of the berries and the dirt to fall through in the receptacle B below without allowing any of the broken portions of the berries to pass through at the same time.

Passing through the frame A, the cylinder C, and the fanbox P is a horizontal shaft, F,

which has secured to it a driving-pulleyJ, the

brushes D, wings E, and the suction-fan H. The brushes D are secured to the outer ends of the'arms which project radially from the` shaft, and which brushes serve to force the germs and dirt through the perforations in the cylinder, for the purpose of separating them from the cracked portions of the berries. The wings E, which are also secured to the arms which extend radially from the shaft, consist of flat plates which are placed at any suitable angle, and which serve to catch all the material which is in the cylinder and throw it outward against the sides of the cylinder, and to raise it upward and drop it back upon the bottom of the cylinder, for the purpose of separating the coarse and fine particles, and to enable the suction o f the fan to catch all of the tine particles and draw them away. The broken portions of the berries, after passing the full length of the cylinder, are discharged through the spout K, as shown in Fig. 2. As these broken portions leave the inclined portion of the spout they are subjected to an upward draft from the fan H, for the purpose of drawing away any of the line particles which may have passed through the cylinder.

In the upper portion of this spoutKis placed a valve or slide, Q, for the purpose of regu-` lating the force of the draft.

In the frame A, just under the cylinder C, is placed the inverted-Vshaped deector R, which serves to contract the opening through the lower portion of the-frame A, and thus increase the force of the draft at this point, for the purposeof drawing away any ne particles of dirt and dust which may have been forced through the cylinder by the brushes D. This upward draft catches the ne light particles of dirt and other impurities, and con- Veys them through the openings I, made in the upper portion of the frame A, to the fan H, from whence they are blown into the dustroom or other suitable place. The suction of the fan H is also exerted upon all of the particles in the cylinder C, not only while lyingupon its bottom, but while dropping from the spout M, so as to remove the dirt and impurities and convey them to the dust-room.

IOO

VThe openings I in the frame are provided with' suitable slides or valves, S, which serve tol regulate the force of the draft from the fan. By means of the construction above described all of the iine particles of dirt are separated from the broken berries and conveyed away to the dust-room. Being unfit for flour, they are turned into feed. The germs and smaller pieces of the broken berries pass through the perforations of the cylinder and drop into the receptacle B, whence they are carried to the rolls to be made' into flour.

The seam-dirt and all other impuritiesV are thus separated from the germs and broken pieces of the berries at the Very earliest possible stage in the process of making flourviz., immediately after the first break. By this means a finer and Whiter flour is produced than can be done where this separation does not take place, as it is impossible to remove the dirt from the flour at the Iater stages of reduction after it is once ground fine and incorporated with the fiour.

Having thus described my invention, I ciairn- 25 lA separator composed of the frame A, provided with the air-passages I G, valves S Q, which control the passages and regulate the draft of the fan, the open-topped perforated cylinder, the shaft F, carrying brushes and 3o Wings and having the fan secured thereto, the discharge-spout K, and the fan-boX, substantially as shown and described.

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

ABRAHAM N. IVOLF.
