` CASE To all whom i1/may concern :4 y

Be it known that I,-GEORGE W.BROWN,=of Gralesb urgcountyof Knox and State of Illinois, yhave linvented certain 'new and-@useful Improvements `in Corn-Planters, of which the followingis aj'speciiication:

The present invention relates to improve; ments in ,that class of-cornlplanters carried upon wheels, or `wheels and runners, and in which what is known as`a slide seedf-cup-bar is used `for separating theseed intended for each hillfrom the massof seed inthe box.; and it consists partly inimprovements in the seed-cupban and partlyiin improvements in the cap and the arrangement of the cut-oi's, and partly in the throat to the seeditube, and partly in devices within the seed-tube, and constituting what is generally known as the lower dropper.

To enable those skilled in the art to understand and use my invention, I will now prois or may be carried into effect, by reference to the accompanying drawing, in which- Figure 1 is a perspective view of seed-box, seed-tube, runner, and one end of seed-cup bar. Fig. 2 is a perspective view of the same parts, with the runner and the rear side ot' the seedbox and seed-tube broken away. Fig. 3 is a rear elevation of Fig. 2. Fig. 4 is thelsame as Fig. 3, with the vibrating valve or-lipper removed. Fig. 5 is a sectional view of Fig. 3 on the line w x. Fig. 6\is a top view of the cap and slide beneath it. Fig. 7 is a top view of' the slide or seed-cup bar alone. Fig. 8 is a top view of the throat to the seed-tube, with the parts above removed; and Fig. 9 is a rear elevation of the throat-piece.

The dropping mechanism heretofore used in mahines 'of this class has consisted of a seedcup bar, in which the seed-cups were arranged at some distance apart longitudinally in the bar, and the cut-oft` was so arranged centrally *f in the seed-box` that the seed-cups approached it alternately from each side; and inorder to give each cup travel enough to insure its fill'- ing with seed, with said arrangement it was necessary t6 project the end of the seed-cup bar through the outer Vside ofA the seed-box,

ceed to describe the manner irl-which `thesame seed-tube, andl C the runner. These parts are attached to the other parts of l acorn-planter Vin any usual manner, and may be constructed in any of the ordinary ways, except the seedbox, which only has an opening upon one side for the passage of the seed-cup bar. D is the seed-cup bar, and d d the seed-cups, adjustable in capacity by means of a bar having two limbs, d d, xed by aset-screw, tl. The seed-cups d d are opposite to each other. E is the cap for covering the seed-cup bar and retaining the cut-offs in working position. It is secured'in position by a ledge on one side, and button e upon the other. Its central part is cut away, as shown at Fig. 6, and two yielding cut-oi's, e e, seated, one 'in eachof its ends, with their ends toward each other, and made yielding by the spiral springs e ef. G, Fig. 8, is a top view of the bottom of the hopper, and contains a throat-piece, g, through which two openings, g g", are arranged, lso as to come under the cut-offs e e, respectively, and also contains an opening, 9',- through `which the upper end of the vibrating valve H passes upward to receive motion from the seed-cup bar D, in the usual manner. The

lthroats yor passages g g cross each others paths in descending, asshown at Figs. 3, 4, and 9. I is a gland, extending from the lower end of the throat-piece g downward, as shown at Fig. 4, and dividing the passage through the seed-tube B centrally from the front back to the vertical plane of oscillation of the adja cent side ofthe valve H. J is a wall, extending laterally across the passage through the S" seedtube B, and from a point on thev front side of said passage diagonallydownward to a'vertical plane, same as the rear edge of the gland I. The shape of the vibratingvalve H is plainly shown in the drawings, its axis of oscillation being at the point h, and its plane of oscillation on the face or lower end of the inclines formed by the division of the wall J by the gland I. It will be evident that it will intercept the charges of descending seed alternately on each side of. the gland I in the V- shaped cavities formed between itself and the lower end of the wall J, and release them at the proper time at the rear side and open lower end of the seed-tube, where'they may be seen as they fall therefrom to the furrow prepared for them by the driver from his seat upon the machine. n

Fig. will illustrate 'clearlyT the operation of the seed-cup bar, the dotted lines showing the seed-cup d beneath the cut-oill e', and in a position to discharge its contents through the openin gg', by which they are carried over, as shown by the arrows at Figs. 3 and 4, and discharged into the left-hand passage down the seed-tube, where they are intercepted, as hereinbefore described,by the valve H. On thereturn stroke of the bar D.the cup el will be brought beneath the cut-off e, and the seed discharged to the right-hand channel of the tube, in the same manner as described to the left herein.

An inspection of Figs. 2, 3, and 4 will show clearly that the extreme end of the seed-cup bar does not pass through the adjacent side of the seed-box; and the other gures, in con? nection therewith, will show as clearly that the construction of the cap and seed-bar is such that the seed-cups have abundant travel toinsure filling without its being so extended.

I am aware that corn-planters have been known and used in which the sliding bars reciprocate back and forth through the outer as well as the innerends of the seed-boxes, and that spring or pivoted cut-os, arranged one on each side and toward the center of the seedbox, have also been known and used; and I donot, therefore, now claim such as the invention which I now desire to secure.

What Iclaim as new, and desire to secure by Letters Patent, ,is-

1. The cap E; having the cut-o's e e, one at each end andlat opposite sides of the seedbox, and the sliding bar D, having the seedcups d d arranged opposite to each other and toward one end of the bar, operating substantially as described, to insure the lling of each cup without carrying the sliding bar through and beyond the outer side of. the seed-box, as set forth.

2,. In combination with the cap E and bar D, constructed and operating as described, the crossed passages or ducts g` g', to conduct the seed to the sides of/the divided tube I, opposite to where discharged from the seed-box, substantially as and for the purpose set forth.
