SPECIFICATION forming part of Letters l atent No. 252,803. dated January 24, 188

Application filed July 5, 1881.

To all whom it may concern:

Be it known that I, DEXTER SALISBURY, of \Villiams, county of Oolusa, State of California,

have invented an Improved Grain Cleanerand Separator; and I hereby declare the following to be afull,clear, and exact description thereof.

My invention relates to that class of agricultural implements known as grain cleaners and separators; and it consists in the follow ing construction and arrangement, whereby the objects of my invention are effected, and which will be fully described, and the points of novelty set forth in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my grain-cleaner. Fig. 2 isa transverse section through the screen. Fig. 3 is a portion of the machine with a section of the shoe and screens- Fig. 4 is a longitndinal section of the revolving screen. Fig.

'5 is a detail view. Fig. 6 is a detail perspective view of the means employed for giving motion to the sieves. Figs. '7 and 8 are views in detail, illustrating the manner of applying the troughs or spouts which conduct the grain from the sieves.

The device is adapted to be set upon wheels, as here shown. or it may be made stationary, as desired. Fig. 5 shows the spouts.

A represents the main supporting frame or body. Across the frame, about its center, is the main driving-shaft B, having the pulley O, through which shaft power is applied to the machine.

On one side of the frame A is a side frame, D, upon which is what is known as the cutting-in hopper K, which opens upon a screen or sieve, E, in a shoe, which also'contains another and similar sieve, F, under the first. These sieves are given a shaking motion by means of their common shoe or frame being connected by an arm, a, with an eccentric upon the shaft 11, journaled under the side frame, D. This shaft carries a pulley, c, from which a belt, 0?, passes to a pulley, 6, upon the main shaft B. The upper and coarser sieve, E, has on its front edge a carrier, G, inclined outwardly, as shown. The lower sieve, F, com- 'municates with a carrier, H, inclined downwardly and inwardly and opening into the elevator I, attached to the side of the main frame A and extending to the top. This elevator has a spout, J, which extends downwardly and (No model.)

] opens into a vertical spout, which is the continuation of the suction spout or chamber L, supported longitudinallyabovethe frame. The other end of the suction-spout extends downwardly and opens into the fan-chamber, in which is contained a fan, M. A spout, N, proceeds from the fan-chamber to the end of the frame, as shown, where it opens to the outside. 7 Motion is transmitted to the elevator I by means of the beltf, which passes over a pulley, g, upon a shaft, 27, and over a pulley, j, upon the shaft 7;, motion being transmitted to the shaft k by means of the belt Z from the main shaft B. I

The fan in the fan-chamber M is operated by means of the pulley m, belt a, and large pulley 0 upon the main shaft B. The top of the suction-spout L is made deep, as shown, and terminates in an inclined draft-spout, 0, extending rearwardly, and having an outletvalve, 19,011 its end. It communicates with the spout P, which opens out below.

Supported longitudinally in the frame A, just under the spout N, is a box or casing, Q, having an entrance-pipe and hopper, R, at one end, into which the vertical portion of thesnctionspont L opens. Within the chamber Q is the revolving inclined screen S, consisting of wire-netting fitted upon a frame. The entrance-pipe R opens within this netting. On the outside of the netting attached to the revolving frame are the radial blades or propellers T. The inner end of the revolving screen S opens into a spout, V. To prevent the parfrom becoming again mixed with the coarser particles which find their way out at the lower end of said screen and do not pass therethrough, a partition or flange, q, is formed, projecting-from the inner lower wall of the casing Q, and on a line with the open lower end of the screen. On either side of this partition q are arranged the spouts V and U, the former serving to carry off the coarser particles and the latter the finer particles. The screen S is revolved by means of a belt, r, passing from the upper shaft, it, to a pulley, 8, upon the end of the axis of the screen. The spout V opens into an elevator, W, supported on the side of the frame. The upper end of the said elevator opens into a hopper, X, the bottotn of which is provided with openings t and a slide, a, of

ticles which pass through this rotating screen any approved known form, for the purpose of regulating the discharge of the grain. Under this hopper and supported in the frame A is a series of vibrating oppositely-inclined or zigzag screens, Y, each screen having a bottom plate, a, under it, and separated from it a little.

On the sides of the frame below the series of zigzag screens are inclined carriers Z, opening into each other and discharging as shown. Each screen is made to extend so that its edge is in line with thevertical plane of one of these spouts, while the bottom plates are inclosed at their edges by channels which open upon the next screen below, inclined oppositely. The lowest plate of the series opens into a carrier, A, which is connected with the dischargespout B. These screens I have shown as being contained in two shoes, 0 U, properly hung and made to reciprocate simultaneously in opposite directions by means of the pitmen a a upon the crank-shaft B.

Motion is transmitted to the elevator \V by means of the belt D, passing from the upper driving-shaft, Ir, to a pulley, b, upon the elevator-shaft.

Having now described each portion of the machine and their connections, the following description ofits operation will render it clear: The grain-sacks are placed upon the side frame, 1), and their contents delivered to the cutting in hopper K. It passes thence upon the vibrating screen or sieve E, by which the straw and very large impurities are stopped, being carried off by the carrier G. The grain falls upon the under screen, F, and the tine dust and sand passes through,whilc the grain is taken by the carrier H to the elevator I, by which it is raised up and dropped into the vertical suction-spout L. Here, the grain being subjected to the strong suction of the draft from the fan N, the light wheat and stuff called chicken-feed is drawn up into the suction-spout. On top this light wheat, finding an enlarged chamber in the suction-spout, falls down and is carried off by the spouts O and I, and is discharged. The very light dust and material is sucked in farther by the fan, and passes through it and is blown out through the spout N. The grain in the vertical suction-spout fallsdown into the inlet or entrancehopper and spout It, and is carried into the inclined revolving screen S, and islprogressed forward. The mustard seed and other impurities smaller than wheat drop through the revolving screen into the casing or box Q, in which it is caused to move forward by the radial bladesTto theopening spout U, whence itis discharged. The grain in the revolving screen passes forward and is discharged through the spout V into the elevator \V, by which it is carried up and discharged into the hopper X. It then passes through upon the first of the inclined zigzag screens Y. The barley, being larger than wheat, is dropped over the edge into the carrier Z below. The wheat passes through the screen upon the bottom plate, a, and is discharged upon the next oppositely-inclined screen. Vhatevcr barley has remained with the wheat here drops over the edge again into the carrier Z, while the wheat is carried on down to the following screens, and is finally discharged into the carrier A. The vibrating motion of the zigzag screens causes a perfect separation.

I atn aware that there is nothing new in my vibrating screens, or in my elevators, or in any of the parts taken separately. I know that elevators are common, and that the zigzag screens have been used, and that a blast of air has been applied for the purpose herein shown. In all machines heretofore known, however, the arrangement is different. In some there is but one elevator and ordinary screens, and in others the elevator takes the wheat directly from the cutting-in hopper and delivers it upon the zigzag screens, thus aecomplishing the result of separating the barley and large impurities at once, while the grain is full of the smaller chaff.

lnmy invention I deem it best to clean out the small chatt'first, so that when the grain is delivered to the screens they will have nothing to do but separate the barley from the wheat, and cannot becotne clogged. In stating, therefore, what I claim as new, I do not wish to be'understood as claiming any one part, broadly, but I confine myself to the construction and arrangement of the parts into an entire machine, whereby I accomplish my object.

Having th as described my invention, what I claim as new, and desire to secure by Letters Patent, is-

.l. In a grain cleaner and separator, the combination of the vibrating screensE and F,carriers G and H, elevator I, suction-spout L, said spout having a deep chamber above and an exit-spout, O, suction and blast-fan M, and spout N, arranged substantially as and for the purpose herein described.

2. The combination of the elevator I, suetion-spont L, fan M, and rotating inclined screen S, and an exitspout, U, arranged substantially as and for the purpose herein described.

3. The combination of the elevator I, suetion-spout L,fan M, inclined rotating screen S, the exterior radial blades,T, the box or casing Q, and the exit-spout V, substantially as and for the purpose herein described.

4. The combination of the rotating inclined screen S, having exit-spout V, the elevator W, hopper X, and series of vibrating oppositelyinclined or zigzag screens Y, having bottom plates, r, and carriers Z and A, arranged and used substantially as and for the purpose herein set forth.

In witness whereof have hereunto set my hand.
