SPECIFICATION forming part o'f Letters Patent No. 322,220, dated July 14, 1885. I Application filed March 28, 1885. (No model.) i

To all whom it may concern:

Be it known that I, SOLOMON DAvIEs WAR- EIELD, of the city of Baltimore and State of Maryland, have invented certain Improvements in Corn-Silkers, of which the following is a specification. Y

This invention relates to certain improvements in that class of corn-silkers in which the silk is removed from the cut corn.

In the drawings, forming a part hereof, Figures I and II are exterior views of t-he machine as seen from different sides. Fig. III is aplan of the machine with some. minor parts thereof removed. Fig. IV is a vertical section taken on the dotted line x x, Fig. III. Figs. V and VIare details of the machine.

A is a frame supported by legs A. y

B is an inclined endless conveyer belt or apron, carried by rollers B. These rollers have gudgeons c, adapted to turn freely in boxes a in the frame A.

Gis a second endless belt or apron, carrying silking-iingers b, and arranged so asto bring the fingers on its under side nearly in contact with the upper side of the conveyer-belt B, as shown particularly in Fig. IV. The belt C is also mounted on rollers, which are denoted by C', and have gudgeons b', adapted to rest in bearing-boxes c in the frame A.

The beltsB and C are driven as follows, the direction of their movement being indicated by arrows in Fig. IV: A main driving-shaft, c', supported by hangers D, is providedwith a driving-pulley, D. Ou this shaft c is a sprocket-wheel, d, connected by a chain-belt, d', to a second sprocket-wheel, E, on the gudgeon a of the upper and driving roller, B', of the endless conveyer-belt B.

E is a smaller sprocket-wheel on the same gudgeon a, and connected by a chain-belt to a larger sprocket-wheel, F, on the gudgeon b of the upper and driving roller, C, ofthe endless belt C. On the gudgeon b is also astill larger sprocket-wheel, F', united through the medium of a chain-belt to a smaller one, e, on the brush-shaft e', which is suitably supported on the frame A. This shaft is provided with a rotary brush, F, preferably of the spiral kind, and set substantially the same as that shown and described in Letters Patent No. 309,999, granted to me on the 30th day of December, 1884, for a eorn-silker.

G is a hopper supported between the two g, on the shaft g', adapted to vibrate in a sleeve, i

h, projecting from the frame A. The vibratory motion of the shaft g' is effected by means of an arm, G, fastened thereto, which is connected by the rod h to a crank, Gf', at the end of the fan-shaft H, hereinafter alluded to.

By referring to Fig. V it will be seen that the distributing-rods f have pins z', which-rest in slots t" in the rocker g. The Yfull and dotted delineations of 'the rocker and certain'of its attachments indicate the extremes of their movement.

By simply employing pins to connect the rods f with the rocker gr the said rods, with their distributing-bars, may be easily removed for cleaning or other purposes and replaced while the machine is in operation; and to admit of this removal the hopper G has slots j, v

will be described, and their uses set out in the description of the operation of the machine v which follows: Supposing the machine to be in operation, corn, as out from the cob,y is poured in the hopper G. By the action of the distributing-bars the corn, in falling to the conveyor-belt B, is evenly spread over its surface and to anniform depth. `The distributing-bars also serve to separate from the corn any pieces of cob that may be contained therein. The corn is carried by the conveyerbelt B toward a second hopper, I, hereinafter described, and against the silking-ingers b, which are moving in an opposite direction and at a less speed. The object in moving the finger-belt at a less speed than the conveyer-belt is to avoid the danger of the fingers carrying the corn from the machine. Vhen the corn to be silked contains the scrapings of the cob, such scrapings are not evenly mixed with the grain, and if the corn is packed in this condition one can Will contain more of these scrapings than another. This difficultyv is entirely obviatcd by forcing the corn on the conveyerbelt against the fingers, Which serve to break the lumps of scrapings and distribute the particles thereof evenly among the grain. While the ngers are breaking the lumps of scrapings and mixing the same with the grain, they are also removing the silk from the mass, and the silk is carried by the fingers to the brush F, which in its revolution in a contrary direction to the moving fingers cleans them and throws the silk to the silk-box I', supported on the frame A. Ahood, J, (shown in full lines in Fig. IV and in dotted ones in Figs. I and IL) prevents the scattering of the silk and guides it to the silk-box I. The second hopper, before alluded to and designated by I, is supported by springs J', bolted to the frame A, and is vibrated laterally of the machine through the medium of a bell-crank, 7c, pivoted at Z, and a rod, Z', attached to the crank G on the fan-shaft H. The hopperI consists of a box, open at the side next to the machine. (See Fig. IV.) This bok contains a crosspiece, m, from which project bars m', as shown in Figs. III and IV, and is placed sufficiently close to the conveyer-belt to remove corn therefrom, but not to scrape the belt. The conveyer-belt, to which considerable chaff and short silk adhere, is finally cleaned by means of a Wiper, a, attached to the frame A. This wiper is preferably made of strips of rubber or other flexible material fastened to a bar, n, and is adjustable with reference to the belt, as shown particularly in Figs. IV and VI. A pan, K, hinged to the frame A at 0, serves to catch the matter wiped from the conveyerbelt.

L is a fan of any approved construction, the rotary Wings of which are secured to the fanshaft H, before alluded to. The dischargenozzle o of the fan is toward the open side of the hopper I, and the air forced therefrom passes through the corn shaken through the bars m and removes from the grain chaff and short pieces of silk contained therein. The rapid shaking of the bars m' lightens up the mass of corn as it falls through the hopper and facilitates the passage of the air through the grain. The bars m also serve to catch any pieces of the cob that may have passed through the first hopper. The fan-shaft H is driven from the main driving-shaft c through the medium of the gear-Wheels L and IVI, as shown in Fig. I. The silked corn falls from the hopper I to any suitable receptacle placed underneath thereof. Side boards,N,screwed to the inner faces of the frame A, prevent lateral dispersion of the grain from the conveyer-belt. The

side boards are grooved to receive the edges of the belt. (See Fig. VI.) An adjustable binding-roller, O, (see Figs. I, II, and IV,) is used to take up the slack in the conveyerbelt.

The principal object in having the silkingvfingers on a moving belt is to admit of the said fingers being easily cleaned, but as other means for cleaning the lingers could be employed the fingers could be fixed or stationary without departing from the spirit of the inventiomwhich aims to remove the silk from a body of corn by conveying the same against and through a system of silking-fingers.

I do not nrestrict myself' to the use of the various devices shown for driving the belts and for effecting the vibratory movement of the several parts of the machine, as it is evident that other contrivances could bc employed to produce the same effect.
