lo @ZZ whom t may concern: Y

Be it known that we, HARRY J. SILVIS, a residentof Mansfield, in the county of Richland, and HENRY WHITE,1a resident of Marion, in the county of Marion, State of Ohio, citizens of the United States, (whose postofiice addresses are Mansfield, Ohio, and Marion, Ohio,) have inventednew anduseful Improvements in Separatrs, of which the folio lowing is a specification.

Our invention relates t grain-separators; and it consists, primarily, in the provision of a series of successively-operatin g beaters travelin gin conjunction with a conveyor composed of Z-shaped slats or bars", the object being to push and draw the grain over a corrugated and perforated surface.

Further objects are to construct a device which will separate, clean, and scour grains zo of all kinds without the use of crank-shafts,

thereby reducing the vibration of the mechanism; secondly, to reduce the size and weight of devices of this nature and at the same time increasing the capacity and dura- :5 bility thereof; thirdly, to provide a simple means of constructing a separator of metal; fourthly, to provide means whereby a continuous and positive feeding of the grain to -the separator is eected, and., tifthly, to ob- Viate the use of belts in transmitting motion to the various parts of the mechanism.

Our invention further consists in certain other novel details of construction and combinations of parts, which will be particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of our invention, the casing thereof being shown in section. Fig. 2 is a detail top plan view of one of the trav- Fig. 3 is a sectional side elevation of the parts shown in Fig. 2. Fig. 4 is a detail top plan View of the adjustable screen. Fig. 5 is a detailsectional View, in side elevation, of the adjustable screen. Fig. 6 is a sectional View of our invention, the cover of the casing being removed. Fig.'7 is avertical section on the line'o 0 of Fig. l. Fig. 8 is a top plan view of a portion of the corrugated screen. Fig. 9 is a Vertical seco improvements in seria no. 69,142. or@ man.)

tion through Fig. l, portions of the mechanism beingornitted.- Fig. ll is a detail view of the lug on the traveling beaters. Fig. l2 is a detail yView of one of the Z-shaped bars T5, and'Fig. 13 is a detail View showing the 5|;

arch shape of the iingersj.

The frame a is rectangular in form and is constructed of angle-iron of anysuitable size. The frameworkis thencovered and inclosed with sheet metal a', forming the sides and 6o top of a casing, the sheet metal secured by rivets or other suitable means to the lframework. ',lhe casing and framework are mounted on wheels 1 l in any suitable way, the manner shown being the preferred form.

Extending some distance 011 top of the casing is a supporting-plate 2, downwardly inclined at' one end 3 above an aperture 4 in the casing. This plate is suitably retained in place in any desired manner. d2 are j onrnaled in suitable supports at either end of the plate 2, and extending around the rollers and encircling the plate, which acts as a support therefor, is the feeding-belt d of any approved construction. An idler-roller d3, suitably journaled on the upper edges of the sides of the casing, is located beneath plate 2, over which idler the belt d is adapted to travel, the idler operating to guide and tighten the belt.' 8o

Supported on an odset 5 on the casing is a hinged cover 6, adapted to inclose the aperture 4 in the casing. Beneath. the cover and suitably journaled in supports f2 2 is a shaft 7, upon which is mounted the breaking-roller f, the periphery of which is provided with a plurality of serrated knives p4, projecting at varied angles toeach other. This roller is 1ocated just over the traveling feed-belt d and is adapted to cut and spread the grain on the 9o feed-belt to prevent it from bunching. i A sprocket-Wheel p2 is secured on the shaft 7.

Located and supported within the casing is a trough 8, provided with aprojecting lip 9. A drum or cylinder c is mounted on a shaft l0, journaled in bearings in the sides of the casing, and this shaft and drum are mounted directly over the trough 8. A plurality of arms curved in the direction opposite to the 5o tion thereof. Fig. 10 is'a vertical cross-sec- Rollers d 7o v direction of rotation of the drum project raroo dially from the periphery thereof and operate to throw the grain and straw which falls into the tronghont onto the traveling beaters 11 11, hereinafter described.

The shaft 10 ofthe cylindercisprovided with a bevel gearwheel 12 and sprocket-wheels 13. A chain c' passes over one of these sprockets 13 and over a similar sprocket-wheel 1st on roller d3, whereby the feed-belt d is given its motion. The trough S is just below the aperture 4.- in the casing, through which the grain and straw are delivered onto the drum or cylinder c, which carries it down into the trough and then forces it out onto the projecting lip. Above this lip and with but a narrow space intervening is located a rotating beater g, mounted upon a shaft 15, the ends of which are received in bearings in the sides of the casing. A sprocket-wheel 16 on shaft 15 receives thereon a sprocket-chain 17, which also passes over a sprocket-wheel 13 on the shaft 10, thereby revolving beater g.

The rotation of the beater g tends to throw the grain and straw upon the traveling beaters 11. Shafts h3 Zt are journaled in bearings in the sides of the casing. Large sprocketwheels 19 1E) are secured on the shaft 72.3 near the ends thereof, and worm-wheel 2O and sprocket-wheel 2l are secured on the shaft at points outside the two sprocket-wheels. A drive-chain 22 passes over sprocket-Wheel 2l and over the sprocket-wheel p3 on shaft 7, whereby to rotate the breaker-roller f.

The shaft h is located on the same horizontal plane as is shaft h3, and mounted on shaft Zt and near either end thereof are two small sprocket-wheels 18. Chains composed of links h3, connected to one another in any approved manner, pass over sprocket wheels affording a strong projection.

18 19 on shafts h h3, respectively. The links h6 are provided at one end thereof with lips h3, and certain of the links are also provided with semicircular lugs h4, the lugs being apertured to receive the end of a shaft lc. The links which have the lugs h4 formed thereon are spaced apart a su flicient distance to allow the fore endsj of one set ofvtraveling beaters 11 to rest upon the rear ends j' of the preceding set of traveling beaters, the beaters being journaled or mounted on the shafts 7c. In other words, the links carrying the lugs h4 are spaced apart an approximate distance equal to the length of the traveling beaters. These beaters consist of a plurality of metallic-fingered plates, the fingers of which are concavo convex in cross section, tapering from front to rear in a constantly-increasing arc of a circle, (shown in Figs. 2, 3, and 13,)

The lingers on each beater merge into an integral fiat body portion j', which is secured to a strong supportingcross-bar23in any approved manneras by means of rivets, for instance. These cross-bars 23 serve as a reinforce and support to the beaters proper. Integral with each of these cross-bars 23 is a lug 24:, provided `with an aperture h5, through which shaft 7c passes. The end 7c3 of the lug 24 is longitudinally slotted in the arc of a circle, as shown in dotted lines in Fig. 3, and within this slot is received a roller k3, 'ournaled in the walls of the slot. I have shown a series of four traveling beaters mounted on a single shaft 7c; but there may be either a smaller or larger number, according to the width of the casing a. The shafts 7c may also be mounted to extend at an acute angle to the direction of movement instead of at right angles thereto and to the sprocket-chains.

Mounted diagonally in the sides of the casing ct' are a number of shafts Z3, which shafts extend between the traveling sprocket-chains carrying the beaters 1111 and nearer the upper than the lower chains. The ends of these shafts are received lin adjustable bearings, whereby the shafts may be moved in circle toward or away from the upper chains. These bearings consist of circular plates Z, rotatably secured at their centers to the sides of the casing by means of bolts or other securing means Z'. Eccentrically located in these circular plates are the bearings Z3, in which are held the ends of the shafts Z3. Thus it will be seen that by rotating the circular 'plateZ thepositions of the shafts Z3, eccentric-ally carried by the plates, may be altered and changed. Rotatably mounted upon each of the shafts Z3 are a series of rollers m, which may be circumferentially grooved, as shown. The rollers 7c3 in the ends of the lugs 24 of the traveling beaters are adapted to impinge against the rollers m, and owing to the motion of the chain the rollers 7a3 override the rollers m; but in so doing the lingered plates with which the rollers 7c3 are connected are caused to rock on shaft 7c, thereby giving the beaters an oscillatory or swinging motion in the arc of a circle. The rollers fm are spaced apart on shafts Z3 sufcient distances to permit of the contact of the rollers 7c3 therewith, and since the rollers 'm are located on the shafts Z3, extending `diagonally to the direction of motion of the traveling sprocketchains and beaters, it will be seen that the rollers 7c3 contact with rollers m successively and not simultaneously. The adjustability of the shafts Z3 permits the rollers m to be engaged by the several rollers 7c3, located on a single shaft k, at greater or lesser intervals, as desired. Thus whenV the roller 7a3 on the first one of the series of beaters located on a single shaft 7c first engages one of the rollers m on the shaft Z3 the remaining beaters on the shaft 7o are horizontal, their fore ends resting upon the rear ends of the preceding series; but as the rst roller 7c3 proceedsto override roller 'm the next one of the series of rollers 7c3 engages its respective roller m, and so on until the majority or all of the beaters are at some point in their arc of oscillatory movement. This motion serves to beat up the grain and straw deposited upon the traveling beaters, which form an oscillatory floor therefor.

IIO

VLocated beneath the traveling sprocket or beater chains is a corrugated and perforated plate n, extending some distance beyond the discharge end of the beaterchains, which drops the threshed grain and straw upon the plate n, which plateis secured at one end to an inclined supports. The grain and straw being discharged upon the corrugated table n are spread thereupon by the ends j of the beaters 1l, which drop by gravity thereon and are drawn thereoverby the movement of the sprocketchains, thus drawing the grain over the table n, scouring and cleaningv it, and finally causing its separation from the straw and chaff by drawing the grain to the perforations r in the corrugated table.

Beneath the table 'n are a pair of traveling sprocket-chains, composed of links r?, having lips h3. The chains pass over sprocketwheels r2 r3, secured upon shaft-s 2526, supported in the sides of the casinga at either end thereof. Equidistantly located on these traveling-chains and intersecting the horizontal plane thereof are Z-shaped bars fr, secured to the lips h3 of thelinks 'r7 of the chains.

Supported in any convenient manner between the members of the traveling table is a second perforated corrugated table n, upon which the ends of the bars T5 are adapted to bear, The grain falling through the apertures of the table n rests upon the second stationary table n, where it is again scoured, cleaned, and spread anddrawn over the surface of the table n by the shaped bars r5 until the grain falls through the perforations r6 in table ns to and upon the bottom a2 of the casing, which is corrugated for a portion of its distance. The remainder of the bottom vis slotted in avzigzag manner, as shown in Fig. 4, and is provided at one end with a depending lug 27, an adjustable sliding member 28, comprising zigzag plates and-correspondingly-shaped intervening spaces adapted to register with the spaces and plates of the bottom of the'separator.- This sliding member 28 is` provided with'a depending lug screw 30 is received in an aperture in lug 27 and a threaded aperture in the lug 29, whereby to regulate the size of the opening through which the grain is to fall. The free end of the sliding memberis supported upon a bar 31.

An irregularly-shaped Aframe 32 depends from the casing ct, and within the chamber thus formed is a rotatable fan 33, secured on a shaft 34. This shaft 34 is driven by any suitable means and has secured thereon a bevel gearwheel 35. A deflectorplate 3b' extends into the chamber in front of thefan. v

In the lowest part ol the chamber an auger conveyer 37 of any approved `construction is located and operated by any suitable means.

A pair of Vertical notched bars u are located in the depending chamber and a screen u is provided, the edge of which is received in any of the notches in the vertical bars u',

ends of the Z the free end of the screen resting upon the inclined wall of the frame 32; and being directly beneath the adjustable sliding member 28. l

The grain which has been separated from thestraw and has fallen upon the corrugated portion of the bottom of the .casing a' is drawn overthevcorrugated bottom by. the ends of the the zigzag openings 38, graduated in size by the adjustable sliding member 28. The grain falls through the openings and upon the adj ustable screen u, where any chaff remaining with the grain is separated therefrom. It is not necessary, however, to use the screen, and in case it is not used the grain will fall upon the inclined portion 39 of the wall of the chamber, whence it will roll down to the auger 37, being subjected to the action of a blast of air from the fan 33 during the descent from the openings 38 to the auger.`

A rotatable rod S4, suitably supported in bearings 40 40, has at one end a bevel-gear 4l, meshing with the bevel-gear 35 on shaft 3,4. The opposite end of rod S4 likewise carries the bevel -gear 42, meshing with bevel gearwheel l2 on shaft 10, thereby giving motion to shaft l0, which shaft carries the three sprocketwheels 13, over which runsprocketchains c' and 17 to the sprocket wheels 14 and 16 on shafts d2 and l5, respectively, as

Z-shaped bars r5 until it reaches heretofore described. A third sprocket-chain 43, passing over a sprocket-wheel 13 on shaft l0, extends around a sprocket-wheel 44 on shaft 25,'thereby giving motion to shaft 25 and to the traveling sprocket-chains carrying` the Z-shaped bars 15.

Located intermediate the length of rod S4 is a worm-gear g3, meshing with a wormwheel 20 on shaft h2, thereby giving motion to the sprocket-chains carrying the traveling beaters l1 ll, and a sprocket 2l on this shaft h2 is connected with a similar sprocket p2 on shaft 7 by means of chain 22, thereby givingy motion to the cutters on the breaker-wheel f.

By means of the above construction the separator can, be composed entirely of metal, making it of minimum weight.- All motion is transmitted by means of sprocket-chains,

sprocket-wheels, an inclined shaft, and gears.

It will also be observed that the separating and cleaning of al1 kinds of grains are accomplished without the use of crank-shaf ts, thus reducing the vibration of mechanism to a minimum.

It is evident that many changes might be made in the form `and arrangement of the several parts described without departing from the spirit and scope Of our invention, and hence we do not wish to limit ourselves to the exact construction herein set forth; but,
