SAMUEL BAR-LEI, OF- Keats CREEK, VIRGINIA.

. THR s INeynionmn V Spe ifi at n otL t e Patent N 5,137, dated June 5, may.

To all whom it may concern I Be it nown that I, SAMUELBA LE of Kerrs Creek, in the county of Rockbridge and State of Virginia, have made certain new and useful Improvements in the Man--v r of C n t ucting M hines r Thres ing and Cleaning Wheat and other Grain; and I do hereby declare that the follow-.

. ing is a full and exact description thereof.

My threshing and cleansing machine does, not differ materially in itsgeneral QOnStIllO1 tion and operation from some other ma-. chines for a like purpose, but I have made improvements in certain parts thereof by c which it is rendered more efiicient in its operation than those heretofore used.

"In the. accompanying drawing Figure 1, is a side elevation of the machine; Fig. 2, a vertical section of itthrough its middle, from front to back, andFig. 3, is a top view of it, the cap, or cover, B, whlch is 1 immediately in the rear of the threshing cylinder being removed for the purpose of} showing the whole of the upper part of the shaker, or separator, on which the straw is to be carried out clear of the machine, whlle;

the grain falls through to be operated on by the cleansing apparatus. These drawings are made on a scale of an inch and a half to the foot; but, of course, the machine may be larger, or smaller, but that represented is of the ordinary size. In each of these figures where the same parts are represented they are designated by the same letters of reference.

A, is the inclined feeding board down which the grain to be threshed and cleaned is to be passed.

A5, is the threshing cylinder, and A", the concave adapted to said cylinder. The

spikes, or heaters, by which the threshing.

is to be effected may be formed and arranged in any of the known modes of aflixing and using them. B, is a cap, or cover,

against which the straw and grain are thrown as they escape from the threshlng apparatus. O, C, D, D, is' the shaker, or separator, which receives the straw and grain as they leave the threshing cylinder. This shaker is peculiar in its construction, its bottom or floor, consisting, alternately of a covering of boards C, C, which are grooved into steps, from side to side of the shaker, and of rollers D, D, that turn on pivots at their ends. These rollers I make about three fourths of an inch in diameter, and place pended, nd ma t r te in. he fo lo ing manne a, is a. s rap the uppe end o wh ch s a t ched by a iei tp to. the i e them about half an inch apart.

There are two fan wheels for completing the cleansing of the grain, one of which I will call the large, and the other, the small fan wheel. In the section Fig. 2, the large fan wheel is shown at E, as driven by a band Q, from the first mover. E, Fig. '1, is a whir-l or the axis of-said wheel, from which a strap R, R, ismade to drivethe thrashing cylinder shaft 6. From the shaft of the fan E the small fan G, (Fig. 2) may also be driven by a strap w, 'w, passlng around a whirl G (Fig. 1). on its shaft. The whirl T, carrying the shaker, may also be driven by the same shaft by a strap f, 1. By the descent and vibration of the shaker, aidedby the form given to the grooves C, C, the grain and straw will be made to pass toward its rear end, and the grain and chaff will fall between the rollers D, D, on to the inclined boards F, F, (Fig. 2,) that extend from side to side ofthe machine, andconduct them down to the cleaning apparatus, by which. the grain will be separated from the foreign matter. Z, Z, Z, is a large 'intoa second shoe, or vibrating box.

ated on'by the'wind from the large fan, passing through theztube, or'channel, H, H, Fig. 2. The top of the shoe Z, consists of an inclined board 9, and ofslats 721,70, placed obliquely, like those of a blind shutter, at an angle, say of about 45 degrees; the wind from the large fan wheel passing up through the spaces between'these slots, will drive out the chafi and other matter lighter thanthe' grain, through an opening at K. The bottom of the vibrating box Z, is elevated as shown at Z, so as to give an upward direction to the wind, and to allow a free descent of the grain 'down the inclined; bottom z',hz', T e

grain, and other heavy matter falling on the inclined bottom 2', 2', will slide down it,

and enter a second vibrating shoe S, S, by passing through an opening'i, on to a screen J, J ,that forms a portion ofthe upper part of said shoe, and the meshes of which are of such size as to allow the grain to pass through, and to exclude larger substances.

The wind from the small fan G passes from 25 vibrating shoe S, S, and is directed upward it through the tube, or channel I, I, into the by the inclined board S and passes with such force through the screen J, as to drive off all matter lighter than the grain which passes through it and on to the bottom L, L,

of the shoe, where 'it passes on to a screen N, N, which allows the cockle,andlsmallj seeds to enter the screening box P, and delivers the cleaned grain into the box 0. In

the tubes, or channels H, H, and I, I, there are shutters w, w, and y, y, thatmay be raised or lowered at pleasure, and these serve to regulate the entrance of the wind Having thus fully described the manner: in which'I construct and arrange the respective parts of my machine for threshing and cleaning of grain, what I claim therein as new, and desire to secure by Letters Patent is, y Y

1. The manner in which I construct the shaker, by forming its bottom of fluted boards, and of rollers turning upon pivots,

substantially in the manner, and for p the purpose set forth; and

2. I claimthe particular manner in which I have arranged and combined the two fan .wheels, and the two vibrating boxes, or

shoes, operated' by means of the vibrating bars, and otherwise constructed and. actu:'

ated in the manner described. SAMUEL BARLEY. l Witnesses? i i THos. P. JONES, LEM. WILLIAMS.
