GRAEN-DISTRIBUTER.

Specification of Letters Patent.

Patented June 5, 1908.

Application filed February 13, 1984.. Serial No. 193.374.

To aZZ whom it "may concern:

Be it known that we, JoHN SMITH and NOAH L. Hnouamn, citizens of the United States, residing at Liberty, in thecounty of Union and State of Indiana, have invented certain new and useful Improvements in Grain-Distributors, of which theiollowing is n. specification, reference being had therein to the accompanying drawings.

This invention relates to greimdistributers, and is in the nature of on improvement upon that class of devices of which the type is found in Letters Patent Nos. 310,228, of January 6, 1885; 315,168, of April 7, 1885, and 317,204, of May 5, 1885, to JOl1I1;L; Ititer. This class of distributors employs e.- seed-cup into which projects a fiutcdseed wheel or roll, movable lengthwise oi its axis, in conjunction with a cut-oil at one side thereof, and moving longitudinally in miiscu therewith, the speed of the seed-wheel being constant and the feed being controlled by the extent to which the seed-wheel proieotsinto the cup. The cut-oil closes that part of the discharge-mouth of the seed-cu whichisngt occupied by the seed-wheel, an on oh ection to this type of distributor is that the eut ofi and the edecent Walls of the seed-cup form a pocket in which the materiel to be sewn cccumulates, so that the device is not a positive force-feed in all positions of the per-ts.

It is the object of our invention to overcome this objection; and to this end our invention consists in certain novel features which we will now proceed to describe and will then particularly point out in the claim.

In the accompanying drawings, Figure 1 is an elevation, part y in vertical section, of a. structure embodying our invention in one form. 2 is a plan view oithe some. Fig. 3 is a side elevation of the cup with the feed-wheel out 03 and other arts removed therefrom. Fig. 4 is a side e ovation oi the sleeve which carries the cut-off and the inevable well of the cup detached. Fig. 5 is a front elevation of the some, and Fig. 6 is a. detail sectional view showing the mode of mounting the several parts carried by the feed-shaft.

In the said drawings, 1 indicates the seedcup, which has one of its side walls (indicated at 2) detachnbly connected therewith and recessed to receive the usual rosette or rose washer 3, heving the feed-rim 4 and feedribs 5.. :1 H v r 6 indicetesithe feed-shaft, having secured thereon so as to rotate therewith the iluted sced whnnl or roll 7 which passes through the correspondingly-shaped aperture 8 of the rosette in the usual way, the ieedslteft end seed-wheel being longitudinally movable together through said rosette, so as to be projected to a. greater or less extent into the interior of the seed-cup. The food run or flange 4 of the rose-washer 3 extends inward so as to encircle that portion of the roll or wheel 7 which lies within the cup.

9 indicates a non-rotating sleeve mounted onthe Iced-shaft 6 adjacent to the inner end of the seed-wheel 7 end rnovinglongitudinelly with said seed-wheel and shnft. This sleeve carries the upper cut-oi? or gate 10 and lower cut-off or gate 11, which control, respectively, the front, portion of the receivinginouth oi the cup and the discharge-mouth thereof.

In order to provide rneans for insuring the delivery from the discharge-mouth of the cnpiofell of the seed which enters at the receiving-mouth of said cup, we make that side wall of thecup which lies opposite the side Wall in which the rosette is mounted movable toward and from said rosette-beering well in unison with the seed-well end cut-off and give to it a downward and in word inclinstion, so that while its upper end is located eta, uitable distance from the opposite well its lower end elwevs lies adjacent to the end of the eeed wheeh In our preerred construction, which is that shown, inoveble well of the cup is indicated by the numeral 12 end is attached to or formed integrally with the sleeve 9, so as to move in unison therewith. The entire well need not he movable, and in practice we prefer to lorrn the upper part 13 of this well integral with the fixed body of the cup to form a receiving-mouth for the cup, which receivingrnonth has a fixed size. To prevent the escape of the seed from the opening thus formed in the side of the body of the cup when the well is moving inward, we employ a gate or cut-off plate 14, extending horizontally outward from the upper edge of the movable portion 12 of said wall, which gate or cut-off will keep closed the space between the upper edge of the movable portion 12 of the wall and the lower edge of the fixed portion 13 when said movable portion is moved inward from its outermost position.

It will be seen that when the seed-wheel is movedlfrom its position of maximum feed for the purpose of diminishing the feed by withdrawing a portion thereof from the interior of the cup, which movement will be a movement to the left in Fig. 1, the movable wall 12 of the cup will move with the said seed-wheel and will always maintain its lower end closely adjacent to the end of the seed-wheel, guiding the descending grain and delivering it to the flutes of the seed-wheel, whatever the position of this latter may be. In other words, the feeding-throat of the cup is contracted or expanded to conform in width at its lower end to the width of that portion of the periphery of the seed-wheel which lies within the cup. The formation of a pocket between the inner end of the seedwheel, the cut-off, and the opposite wall of the cup, which pocket, of greater or less dimensions, according to the position of the seed-wheel, is formed in the ordinary construction of devices of this character where the opposite wall is fixed, is avoided and all of the grain carried down through the feedthroat of the cup to the seed-wheel is delivered from the discharge-mouth of the cup. The rosette-wheel, with its feeding-rim and ribs, cooperates with the seed-wheel to effect this positive feed of the seed.

By reason of the relations existing between the ribbed feeding-rim of the rosette-wheel and the fluted. roll, taken in conjunction with the inclined movable wall, the distributer as a whole constitutes a positive fUluQ- feed to the successful operation of which each of these elements contributes. By reason of this construction the feed may be positively regulated by moving the feed-shaft 6 longitudinally, and since said feed-shaft may 1 therefore be driven at a fixed rate of speed we are enabled to employ a simple chaindrive or other simple means for transmitting power to the feed-shaft and can dispense with the change-speed gearing which is required the washer abutting against the outer end of the seea'l-wheel and having an annular flange 16 extending into the correspondinglyshaped open end of said whccl. At its other end the seed-wheel has a hub 17, provided with a square aperture to fit the. shaft, said hub extending into one end of the non-rotating sleeve 9, the hub being eylindri al externally and the sleeve having an opening circular in cross-section. A washer 18 at the farther end of the sleeve 9 has an annular flange 19 extending into the end of the sleeve and a square aperture to it the shaft 6. Pins 20 or other suitable devices lying outside of the washers 15 and 18 hold the parts together.

Having thus fully described our invention, what we claim as new, and desire to secure by letters Patent, is*

A grain-distributor comprising a seed-cup having a rosette-wheel mounted in one of its side walls, said wheel being provided with a feeding-flange extending into the cup and having feeding-ribs on its internal surfamga longitudinally-1n ovable rotating shaft provided with a fluted seed-wheel rotating and moving longitudinally therewith through the rosette-wheel, and a non-rotating sleeve mounted on and moving longitudinally with said feed-shaft, said sleeve being provided with cut-offs, the lower portion of the opposite side wall of the (up being inclined downward and inward toward the inner end of the feedwheel and being carried by and movable along with the sleeve, substantially as described.

in testimony whereof we allix our signatures in presence of two witnesses.
