GRAIN- DRILL.

SPECIFICATION forming part of Letters Patent No. 308,899, dated December 9, 1884.

Application filed Juneii), 18S-1. (No model.)

Y simultaneously distribute grain and fertilizing materials, the two being discharged in a mingled current as the machine. advances across the iield; and it consists in certain improvements in the construction of the receiving` and discharging apparatus, as will be hereinafter explained.

In the drawings, Figure lis avertical transverse section through the grain and fertilizer receptacles `and the discharging passages which are connected therewith. Fig. 2 is a rear elevation showing a fragment of the supporting-bar and two ofthe receptacles mounted thereon. Fig. 3 is a perspective plan view showing the manner in which the discharging-tubes are supported. Fig. et is a detail showing the same parts in vertical section.

A is the grain-receptacle, and A is the fertilizer-receptacle, the two being separated by the diaphragm or partition a.

B is the chute leading from the grain-receptacle, and B is the chute leading from the fertilizer-receptacle, b being a partition which separates one from the other. The rear chute, B', is provided at its top with an outwardlyprojecting Bange, b', to receive screws or bolts, by which it is secured to the bottom of the receptacle A.

C and C are respectively the front and rear feed-rollers of the drill. The upper front portion, b, of the grain-chute B terminates at a point in close proximity to the front roller, C, as seen in Fig. l. At their lower extremity the chutes B and B extend a suitable distance into the upper flaring portion of a hopper, D, which terminates downwardly in a short discharge-pipe, which is fitted into an orifice in the supporting-bar E, through which itprojects for a short distance into the upper iiaring extremity of the discharging-tube F, the

upper hopper-shaped portion, f, of which is loosely received within a correspondingly iiaring ring or collar, H. The ring H is pro vided uponI its exterior face with two short oppositely-placed trunnion-like ears or journals, h 7L, which are received within bearings h h, formed in the depending portions of angular supports G G, the horizontal port-ions of which are secured by 'screws or bolts g to the under surface of the supporting-bar E. Grain being supplied to the receptacle A passes through the discharge-oriiice c in the bottom thereof and falls into the space between the rollers C and C', by which it is suitably distributed and carried downwardly. The upper front extremity or scraper, b, of the chute B being, as already stated, almost in contact with the roller C, serves as the roller revolves to detach from theface of theroller any kernels of grain or any other substancewhich by any chance may adhere thereto, and the roller is thus kept in suitable condition to do its most effective work in distributing and discharging the grain. The fertilizing, material falls through the dischargeorilice a of the receptacle A', and as will be seen is kept separate from the grain until both have passed from their respective chutes into the hopper D. The inclination of the front portion of the chute B is such that the grain as it descends is given a direction and an impulse which carry it well toward the rear inner portion of the tubular part of the hopper D, while the fertilizing material is given a direction which causes it to strike the grain-current substantially at a right angle thereto, and the two currents, each falling athwart the other, are thus thoroughly com mingled. As will be seen, the lower portion of the two chutesB and B is cut away or made shorter toward the rear thereof, and, besides, t-he two are placed slightly eccentrically to and toward the front of the hopper D. rlhis construction permits observation, as indicated by the arrow in Fig. l, of the operation of commingling the two distinct materials as they unite in passing from their respective chutes.

In the practical use of this class of devices it is found that a current of air which constantly risesthrough the discharge-tube tends. to retard somewhat the downward ilow of the grain and the fertilizer. To avoid so far as IOC) practicable the effect of this upward flow of air, I place the top ofthe Haring portionf of the tube F a short distance below the supporting-bar E, so that through the annular opening f thus provided thc retardingcurrent may find lateral escape.

rlhe discharge-tube F being composed of rubber or other flexible material, the flaring portion f of the same is readily tted into or removed from its seat in the ring H by being rst compressed bythe hands and'thcn passed the hopper-shaped portionf of the dischargel tube being readily lifted from its bearing, and thus made horizontally adjustable at will, to avoid excessive wear upon any particular porY tion thereof.

Having thus described my invention, what I claim is p l. The combination, with the roller C, of the scraper b at the upper front portion of the grain-chute B.

2. lThe combination, with the fertilizerchute B', of the grain-chute B, provided with the scraper b.

3. The combination, with Ythe roller C, of

the roller C and the scraper b.

4. The combination, with the hopper D, of the chutes B and B', projecting into such hopper, each of the chutes being at its lower eX- tremity inclined upwardly from the front t0- ward the rear, as described.

5. The combination, with the hopper D, of

and projecting below such supporting-bar, and,

the discharge-tube F, supported by its flaring top f in the pivotcd collar or seat H, such haring top being placed a short distance below the supporting Y bar, as and for the purposesV set forth.

7. The combination, with the supportingbar E, of the angular supports G G, secured to such bar and having bearings h h', and the supporting-ring H, havingjournals h 7L,where by it is supported in such bearings.

S. The combination, with the supportingbar E, ol' the angular supports G G, the pivoted or journaled seat H, and the dischargetube F. having l'laring portion j".

S). The combination, with the supportingbar E, ot the hopper D, the journaled ring or seat H, the compressible discharge-tube F, and the annular discharge-openingf, which encircles the lower portion of the hopper D.

l0. The combination, with the grain-chute B, having at its upper extremity the roller C and the scraper b, of the hopper D and the iiexible pivotally-supported tube F.

1l. A iiexible discharge tube for graindrills, which is pivotally-supported and which is axially adjustable in its seat.

In testimony that I am the inventor of the above-described improvements in wheatdrills I hereto subscribe my name.
