MANNER 0F CONSTRUCTING WINNOWING-IVIACHINES.

Specication of Letters Patent No. 1,592, dated May 8, 1840.

To all whom t may concern:

Be it known that we, ABEL LOMAX and AsAI-IEL LoMAX, of the county of Clinton and State of Ohio, have invented new and useful Improvements on Winnowing-Mills; and we do hereby declare that the following is a full and exact description thereof.

The nature of our invention is such that it contracts the winnowing-mill to a much smaller compass than usual, enabling the mechanic to build it at a much less expense, and still facilitate the winnowing operation. The body or framework of our machine is constructed of two side-frames, connected together by the front-board, top-lining, and the two foot-boards. The frame timber except pieces otherwise specified is 3 byy 3 inches square.

That we may conveniently describe our frame, we call one sideframe the near and the other the opposite one. That on which the crankwheel is hung we call the near one, which is constructed of two upright posts, A, A, Figure 2, one 3% and the other 4g feet high, which are framed together by two cross ties B, B. One two feet long is framed on the top of the lower post and into the side ofthe high post 1 foot from the top. The other 2,2; feet long is framed into the lower post 1 foot from its base, and by halving it 8 inches from the other end, and halving the high post 1 foot from its base, they are connected, the cross tie projecting 8 inches beyond the post. Into these cross ties 6 inches from the low post we frame a stud O, to which the balance wheel is hung. On the projecting end of the cross tie we frame a stud D, 2 by 3 inches square, extending up to the top of the high post where they are connected by a cap piece E. The opposite sideframe is constructed of two upright posts F, F, Fig. 3, feet high, which we frame together by means of two cross ties Gr, H. One 2 feet long we frame on the top of each post, and the other 2% feet long we frame into the side of one post 1 foot from its base, and by halving it 8 inches from the other end, and halvingv the other post 1 foot from its base they are connected, the end of the cross tie projecting 8 inches beyond the post; as represented at H. The frontboard, I, Fig. 1, is one inch thick and about 29s feet square, nailed on the sideframes, so that their projecting cross ties stand out in its front as represented at H, H, Figs. 2 and 3. The top lining K, K, we nail on the top of the frame leaving an aperture of suitable The two foot g size for the hopper to rest in. boards, J, J, J, J, Figs. 2 and 3, we nail on the lower ends of the four upright posts.V

Thus the whole frame is connected together. To form the cylinder, L, we cut a circle in e the front-board two feet in diameter in which we nail thin boards,`having them to project 2 inches on the front side rand 1 foot` on theother. To make the inward end of the cylinders fit the shoe so that the air may be directed int-o it to the best advantage, we

`level the two sides and the top, drawing the opening to the form represented-in Fig. 1.

M, M, M, Figs. 1 and 2, represent the boards nailed on the two side bevels, with their lower ends nearest together, and becoming wider apart as they ascend upward.

N, Fig. 1, represents the board nailed on the top bevel. Theform which this top-bevel gives the cylinder may be seen at N, N, Figs. 2 and 3. The side-bevels draw in the sides in the same manner and reduce them to straight lines, so that they fit the side linings of the shoe.

Near the inward end of the cylinder we place a small upright stud, l?, Fig. 3. One end or journal of the fan wheel O, Fig. 3, runs in this stud, The other end runs in a timber Q, Fig. 1 and 3, one end of which we frame to the opposite projecting cross tie, and from there it passesI obliquely upward crossing the center of the cylinder and is fastened to the upright stud D, Fig. 1.

The wings R, R, R, R, Fig. 1,v are framed on the shaftat an angle of about 35 degrees from a right line. The edge o-f the wings going forward, are, by this angle extended near the front end of the cylinder as represented at r, whereas the after edge is inclinedtoward the backward or inward end of the cylinder as represented atV s, Fig. 3.

The wings thus obliquely crossing the shaft are inclined by the motion of the fan wheel, to propel or rather glance the air directly 'through the cylinder parallel with its length.

through it, Ywhich stands on a block in the. foot-board.' 4This pivot andjo'urnal permit Y the board to have a rocking motion. j

In the base-board we setvfour studs or posts U, U, U, U, Figs. 2 and 3. These posts are set twoon'each side" of the planks or base-board, leaning outward that the shoe `may be wider at the top than the bottom.v

The two first are set aboutr3 inches from the inward Vend Vof the cylinder, and the other two ll2 inches from them, near the outward vw#f lend of the board. On the Vinsides of theposts we nail thin lining.V

V, represents the near side of the lining. A portion of this lining projects over the top-bevel of the cylinder as represented at `Y, Fig. 2. On the under `side of this pro- 'A jecting portion of the sidefboard `we fasten a `thin board, which'receives the grain from represented at u, Fig. 3. Below the screen we fasten a boarden, which 'extends partly around the end ofthe shoe. This board separates .the wheat which may pass over the riddles, from 'the chaiand conducts"` it under the fan.

The shaking gear we frame thus: A bar of iron, a, Fig. 2, inchsquare with two jour-v nalsjturned on it is hung to the high post andthe uprightstud, C, each end projecting 2% inches beyond the timbers to which it is hung. On the end which projects beyond the upright stud C, we hang a balance wheel, Z2. One inch fromthe center of this balance wheel we place a wrist on which a pitman works. c, Fig. 2, represents the end of this pitman. `The other end of the pitman works in the near upright stud of the shoe, which in the drawings, Fig. 2, appears to'be just beyond the left-hand AVsideV of the `balance wheel.

the balance-wheel, has, from the turning ofV thebalance-wheel its vibratory motion. OnV the other end of the iron shaft, a, we place a The shoe being' thus connected to whirlor pulley! ,Fig. Vl, around which a Y trap passes from the sm'allstrapway of the the necessary motion.

The orankwhee1,e,Fig. l, is made in any crank-wheel, which gives the balance-wheel Amanner convenient tohave two strapways, `one 16 and the other 2 4Linches in diameter.

An iron shaft, g, `is` passed through theV crank-wheel, which has two journals turned on it, by which it is Vhung to the high post and upright stud, D. j On this shaft we have an iron cr`ank, ].V On the Ismaller vstrapway on the balance-wheel shaft; and `on the larger strapway-we have` one i, passing around a whirl on'the fanwheel-shaft. Thus the .required motion is given to'each portion ofthe mill. 1 p

Y `The hopper m, is made `by nailing four boards together not very dissimilar to those now in common use;` j

' The above described winnowing-mill may be made either larger or smaller than herein described and possess all the advantages ofits form. i i j j v `The advantagesof our Amachine consists in, first, the fanwheel'and cylinder which Very much contract its dimensions; second, the form of our shoe presents very great advantages by giving the most room for the grain while it is the most gross; third, the rocking motion of the shoe which gives equal motionto both ends of the riddles and Vgreater motion to `the upper than the lower part; fourth,.therounded form of ourriddles. Y j V i The parts .of the hereindescribed'machine which, we claim as our invention and for which we wish tofsecure Letters Patent are specified as followszu j j `l. We claim the adapting lof one end of the cylinder to the shoe and thus having the ailr to pass from its end directly into the s oe.

" 2. We claim the mode of arranging the shoe by which weare enabled to communicate a greater motion tothe upper than the lowerpart of it. Y p
