WILLIAM G. MEADOWS AND FRANKLIN DEAN MEADOWS, OF POORS KNOB, NORTH CAROLINA.

CORN-MILL.

Application filed January 29, 1907.

To all whom it may concern:

Be it known that we, WILLIAM C. MEAD- ows and FRANKLIN D. I\/IEADOWS, citizens of the United States, residing at Poors Knob,

in the county of Wilkes and State of North Carolina, have invented a new and useful Improvement in Corn-Mills, of which the following is a specification.

This invention relates to a mill for grinding corn, although it can be used also in grinding feed of various kinds, and the object of the invention is a portable corn mill in which the corn is cleaned prior to its delivery to the burs, the dust, dirt, pieces of silk and shuck being drawn into a fan casing and discharged therefrom instead of being thrown out over the mill or portions of it as in some constructions and a further object of the invention is to deliver the corn through the stationary bur to the runner bur and discharge the same to a sifter through a suitable spout carried by the casing inclosing the burs and a still further object is to provide com- 'mon means for shaking a feed chute and the sifter.

The invention consists of the novel features of construction hereinafter fully described, pointed out in the claims and shown in the accompanying drawings, in which,

Figure 1 is a side elevation of our mill. Fig. 2 is a vertical section taken through the burs, spouts and fan casing, and showing a drive shaft and pulley in elevation. Fig. 3 is a detail perspective view of a sifter and a portion of the shaking mechanism, shown detached.

In these drawings A represents suitable beams upon which are mounted vertical head blocks B, which blocks are bolted to the base beams by means of bolts B which extend transversely through the beams A and extend longitudinally through the head blocks, from end to end. Upon the head-blocks is journaled a shaft O driven by means of a pulley O. A casing D is also arranged upon the beams A, the shafts O passing loosely through the casing. Upon the shaft O and within the casing is loosely and slidably mounted a sta tionary bur D, and keyed upon said shaft is a runner D the said runner being furrowed in the usual manner. The bur D does not rotate upon the shaft O and is therefore termed the stationary bur, but has a slight movement along the shaft, and is trained or set with reference to the runner D by means Specification of Letters Patent.

of threaded bolts E which work through head-blocks B and engage threaded perforations in metal plates E, which plates are secured by soldering or other means in recesses formed in the bur Dv ing D is cut out opposite the runners and provided with a removable side plate D which carries a discharge spout D In the drawings, we have shown one of the plates E and one bolt E but it will be understood that in constructing a machine three of these plates and bolts are employed, so that the bur D can be accurately trained or set with reference to the grinding face of the runner D. l

A spout F is divided into two branches F and F the branch F leading through the casing D and through the bur D and discharging into the space between the two burs D and D The spout F leads downwardly to a fan casing G in which is arranged a fan G also keyed upon the shaft C. In the spout F is placed a depending deflector plate H. A hopper J is mounted upon the casing D and discharges into a feed chute J which delivers the corn from the hopper J to the upper end of the branch F. Air is also drawn in by the fan G through the same opening into which the feed chute J is discharged and all dust and dirt in the corn is sucked under the deflector plate H and drawn down through the branch F into the fan casing G from which it may be discharged into any suitable receptacle.

The deflector plate H prevents any of the corn, even the lighter grains,being carried over into the branch F. To agitate the feed chute J and J 2 is connected to it and a bracket J is carried by the casing D and to this bracket is pivoted a rod J the upper end of which is connected with the arm J while the lower end engages a spiral groove K out into a drum K secured the shaft O. The rocking of the arm J as the drum K rotates imparts the rocking or shaking movement straps M which are connected to the sifter adjacent its ends and also to two of the headblocks. To facilitate the shaking of the sifter, blocks M are secured to a side of the sifter slightly spaced apart, and to the tapered end of the rocker arm rests between said blocks.

From the above description the operation of the device will be obvious. Corn will be fed from the hopper J and through the feed chute J the spout F and will descend through the branch F and through the stationary bur D to the runner and will be discharged therefrom, through the spout DPinto the sitter M. The dirt and dust will be carried to the fan casing and discharged therefrom as already explained.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is 2 A grinding mill, comprising a driving shaft, a runner secured to said shaft, a stationary bur, afeed spout extending through said bur, a conduit opening into the upper part of said feed spout, a deflector in said 2 opening, means for passing material to the upper end of said feed spout and a fan on said shaft to draw a current of air through said feed spout and said conduit.
