Application filed December 3, 1902. gerial No. 133,697. (No model.)

To ctlZ- whom, it may concern.

Be it known that 1, JOHN KAYLOR, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Seeding Devices for Corn-Planters, of which the following is a specificatiomreference being had to the accompanying drawings.

It is a Well-recognized fact that grains of corn are in general more uniform with respect to thickness than in any other dimension, and

I taking advantage of this numerous devices have been constructed in connection with corn-planters whereby the grains would be fed into cells or pockets in a rotating seed plate, each of which cells or pocketswas especially designed to receive and bold but a single grain and that in an edgewise position,

so that the number of grains deposited at one time in the ordinary seed-tube and from thence dropped to the ground could be more accurately gaged or. determined than where the cells or pockets in the seed-plate were so constructed. as to receive the grains in some other position and also liable to receive more than a single grain; In all of such edgewisefeeding constructions, however, with whichI am familiar the grainsare fed verticallyto the seed cells or pockets and the grains in such cells or pockets are pressed uponby the Anotherobjectof my invention is to make, provision for the insertion and retention in l the cells or pockets of'grains that are thicker or more rounding than the ordinary grains.

Still another object of my invention is to provide means for feeding the various grains edgewise into their pockets in such manner the mass of corn in the box.

.that each grain when in a pocket will lie on one of'its broad or flat faces, and consequently have one of its edges toward the side or edge of the seed-plate and which. in the 1 construction shown is also of course toward the side or wall of the seedbox, and to retain the grain in thatposition during the rotation of the plate instead of having them stand on edge substantially vertically, as in the formerconstructions, andalso to provide means for covering the various grains after being deposited in their respective cells or pockets,

so that as they are carried around by the seed-plate they will not bear'theweight of These various objects Iaccomplish as illustrated in the drawings and as hereinafter fully described. That which I regard as new. will be set forth in the claims. i

In the accompanying drawings, Figure l is a top or plan view. Fig. 2 is a side elevation showing the seedbox broken away and also partly shown by dotted'lines. Fig. 3 is a vertical section at line 3 3 of Fig. 1.

Fig. 4 "is a detail, being a section at line 4 a of Fig.

which the corn passes to the ordinary seedtube. Fig. 5 is a top or plan view with the cut-off plate removed. Fig. 6 is a detail, being a perspective view of a small portion of the outer edge of the seed-plate and attached devices. Fig. 7 is a section at line 7 Tot Fig. 5; and Fig. 8 is a detail, being a sectional view at line 8 8 of Fig. 6 through a portion of the seed-plate and showing a device for closing one of the cells or pockets to prevent the admission of a grain of corn thereto.

Referring to said figures of the drawings, 10 indicates an ordinary annular bottom plate having the usual vertical 'ledge 11, around which is placed the lower end of an ordinary ,plate 10, from which rises a central hub portion 14, also preferably cast with the parts 10 and 13, which hub portion, as shown in Fig. 3, projects up through a large central opening in the bottom plate 10.

15 indicates a ring surrounding the hub portion 14 and resting on a shoulder or series which the upper end of the hub portion 14 projects, said plate 20 being suitably connected to the ring 15, so as to be driven therewith. The connection between the plate 20 and. the ring 15 should be such as to enable the plate 20 to be easily disconnected therefrom, and in the form of construction shown the connection between these two parts is by means of complementary projections and notches. As shown, the seed-plate 2O gradually slopes downward from its center, so that the corn thereon will more readily be moved toward its edge to enter the cells or pockets about to be described.

At the edge of the plate 20, and preferably formed therewith, is a series of short vertical projections 21,1ocated at regular intervals, with their inner or forward faces substantially in line with the edge of the plate 20, such forward or inner faces being preferably rounded, so as to present no obstructive corners to the grains of corn that may be moved toward them. From the rear sides of these projections extend an annular horizontal piece 22, the upper face of which is lower than the tops of the projections 21 and higher than the outer portion of the plate 20, which annular horizontal piece is provided at regular intervals with a series of vertical studs 23, each of said studs being located near the outer edge of the horizontal piece 22, one of said studs being located directly opposite the center of the space between adjoining projections 21. The plate proper, 20, the vertical projections 21, the horizontal piece 22, and the studs 23 I prefer to form integrally. The forward or inner edge of the horizontal piece 22 lies about opposite the rear faces of the vertical projections 21, and, as shown best in Fig. 7, the under portion of the horizontal piece 22 between the vertical projections 21 is beveled or inclined backward frotn its forward edge, thus forming recesses that are each adapted to receive asingle grain of corn edgewise.

24 indicates a series of plates, each provided near its outer end with an opening 25, adapted to fit over one of the studs 23, such opening 25.of each plate being slightly larger than the stud over which it fits, whereby each plate 24 is adapted to have, by reason of its loose fit on the stud, a slight vertical rocking at its forward end. Each of these plates 24 projects forward between two of the projections 21 and is of a width at its forward end to substantially fill the space between two projections 21, but not wide enough to bind against such projections. The plates rest upon the upper surface of the horizontal extension 22, and their upper surfaces are substantially flush with the upper ends of the vertical projections 21. These plates 24 are to be so held in place that they will not easily drop from their studs 23 when the seed-plate as a whole is removed from the seedbo'x, and yet the means for so holding them in place should be of a character that will readily permit any one or more of the plates being removed if it is desired to replace it with a plate of the character shown in Fig. 8 and hereinafter referred to or for any other purpose. I have therefore employed for retaining the plates in position a narrow annular spring-band 26, which may be secured at intervals by screws 27 to vertical projections on the piece 22, such projections being in the form of construction shown formed with and constituting a part of certain of the vertical projections 21, these few enlarged projections 21 being indicatcd by 28. The narrow annular band 26 can be'easily sprung up to enable any one of the plates 24 to be lifted oif from its stud 23, but at other times will serve to hold such plates in place when the seed-plate as a whole is removed from the machine.

29 indicates a cut-off plate, consisting, as shown, of a ring portion fitting within the upturned vertical portion 11 of the bottom plate 10, to which it is preferably removably attached in the ordinary way by means of projections 30, that enter recesses 31, cut in the upper edge of the part 11, as indicated in Figs. 1 and 3. The cut-off plate or ring 29 also has a hub portion 32, which is joined to the ring portion 29 by suitable arms 33. The hub portion 32 rests upon a suitable shoulder formed on the upper portion of the other hub portion 14 and is locked in place by a screwnut 34, that is screwed down upon a bolt 35, the head of which is held in the interior of the hub portion 14 by a cross-bolt 36.

37 indicates an angular bracket carried by the ring-plate 29, to the vertical portion of which bracket are secured suitable guardplates 38, the lower ends of which project down below the ring-plate 29 close to the surface of the seed-plate 20 and are to prevent grains of corn from passing out through the large discharge opening 39 in the bottom plate 10.

40 indicates a spring-plate also secured to the inner face of the vertical portion of the angular bracket 37, near one end thereof and near one end of the large discharge-opening 39 referred to, and acting, as do all cut-oiTs for seed-plates, to prevent grains of corn from passing to such opening, except such as are suitably carried in the seed cells or pockets provided.

41 indicates a spring-arm, one end being attached to the vertical portion of the angular bracket 37 and the other or free end lying close to the inner edge of the cut-off ringtially wedged beneath one plate 24.- to force one of such grains away and permit the other to properly settle in, place beneath the plate.

42 indicates arms which in the construction shown are secured to the under face of the hub portion 32 and project over and in contact with the plate 20, or nearly so, so that as such plate 20 is rotated the arms will act to direct the corn toward the edge of such plate.

It will be understood that through the gearing shown the plate 20 can be driven intermittently through the action of a check-row wire on the forks of a check-rower head or can be driven continuously by other means, the first method of driving being of course when the machine is used for hill-planting and the second method whenit is desired to use the machine as a drill-planter. In hillplanting it is highly desirable that the same number of grains of corn be dropped in each hill, and with the grains of corn carried under the plates 24, the plates being spaced a uniform distance apart, it is evident that with each full operation of the check-rower forks the plate will be turned a certain distance and a certain number of grains necessarily dropped through the large opening 39 in the bottom plate 10. Now in caseit is deemed advisable that a less number of grains for each operation be dropped this can be attained by removing a certain number of the plates 24 in the manner heretofore described and substituting in lieu thereof certain other plates, like that shown in Fig. 8, the plate there shown being indicated by- 24, such plate 24* having, as shown, at its forward end a downwardly-projecting lip 24", the lower end of whichcoines nearly to the surface of the seed-plate 20 and of course eifectually prevents the entrance of a grain beneath such plate. If, therefore, the machine had previously been adapted for delivering three grains of corn, for example, through the opening'39 in the bottom-plate 10 at each operation of the check-rower forks and it was desired to reduce the number dropped at each such operation to two grains of corn, every third plate 2 L would be lifted from its stud 23 and be replaced by a plate24 7 By the construction shown it will be evident that between every two vertical projections 21 there is a space which is adapted to receive a grain of corn, and owing to the overlying plate 24 such grain of corn can onter only edgewise, and by the inclined forward edge of the horizontal piece 22 a cell or pocket of sufficient size is formed to receive. asingle grain, and only a single grain, which when in the pocket will lie upon the upper face of the bottom plate 10 and will be swept along on such plate as the seed-plate 2O rotates. In case a grain of corn somewhat thicker than the ordinary grain or somewhat more rounded is delivered to the mouth of the cell orpocket just referred to the plate 24 will give and rise at its forward end by reason of its loose fit on the stud 23,, as before explained, thus adapting the device to the varying widths encountered in a large quantity of corn, which is a feature of much value in machines constructed to receive grains of corn edgewise in the cells or pockets of the seed-plate.

' As shown, each plate 24 is slightly notched on its underside at its forward edge, producing a slight downwardly-extending lip 25", which construction aids in holding a grain of corn properly in its recess.
