IMPROVEMENT IN GORNWLANIRS.

Specification forming part of Letterey Patent No. 14855312, dated March 17, 1874; application filed February 7, 1874.

CASE A.

To all whom fit may concern:

Be it known that I, GEORGE W. BitowN, of Galesburg, county of Knox and State of Illinois, have invented certain new and useful Improvements in Machines for Planting Corn, of which the following is a speciiication:

The present invention relates to that class of corn-planters in which a tubular case is arranged, through which the seed, in measured portions, is conveyed from the seed-box to the furrow opened for its reception 5 and it consists in constructing the valve for intercepting the seed, near the lower end of the seed-tube, with wings for detlecting the descending charges alternately to dual inclines, upon which it is received and retained by said valve until discharged within view of the driver from his seat upon the machine, all as herein after fully described.

To enable those skilled in the art to understand and use my invention, I will now proceed to describe the manner in which the same is or may be carried into effect by reference to the accompanying drawing, in which the similar letters used as marks of reference apply to the like parts in all of the figures.

Figure l is an elevation of the rear side of a seed-tube, and the adjacent parts of a seedbox or hopper, and the lower ends of a portion of the devices constituting my invention. Fig. 2 is the same view, with the rear sides of the seed-tube and hopper removed, and exhibits a full rear elevation of the invention. Fig. 3 is a perspective view of the same parts, as shown at Fig. 2, except the right-hand side of the seed-tube is broken away. et isan elevation of the left-hand side of Fig. 1, with the front side of the seed-tube removed. Fig. 5 is a perspective view of the vibrating valve and two sides of the seed-tube, seen from the front. Figs. 6 and 7 are detail views.

Referring to the parts by letters, letter A represents a portion of a seed-box or hopper, and B a detached portion of the reciprocating bar, which, in ordinary machines, transmits motion to the devices for measuring the ch arges' motion to the vibrating valve, which intercepts and collects the seed composing each separate charge near the lower end of the seed-tube, for the purpose of depositing, without dribbling, in the furrow formed by any suitable furrowopener. The vibrating valve, or ilipper,77

heretofore used in machines of this class, hasV functions were such as to require very light construction. My improvement in this direc-- tion consists in constructing the vibrating.

valve, as shown by letter D in the drawing, with an upper stem end, @which receives the impulse to operate it from the bar B, and is enlarged laterally nea-r its lower end to very nearly the width of the opening or duct in the seed-tube, (see Fig. 2,) at which point it is pivoted at d in said tube, and thence tapered to its lower end in such manner that when at the limit of its throw in either direction, its tapered side -nearest the side of the tube will be parallel therewith. D D are wings, extending at right angles from one side of the valve D, and their sides parallel with the tapered sides thereof, their upper endsopposite the pivot-point d', and their lower ends terminated so as to leave a projecting lower end or tongue, d, of the valve l), as shown plainly in the drawings. E is the valve-seat, and is formed as shown more plainly at Figs. 6 and 7 ,which are .perspective and side views thereof, respectively. It is iitted snugly against the front wall of the seed-tube, its central upper portion e extending baclr to the same vertical plane as the adjacent side of the tongue f, thence downward a short distance in the same plane, its upper surface on each side of the projection c cut into inclined groovesc el., the terminating forward ends of which are in the same vertical plane as the outer end of projection e, and together therewith form faces borne upon by the tongue d in its vibrations. rlhe block E is located in the seed-tube with its lower or discharging end below the plane of the lower end of the rear wall of said tube,

and its upper end situated relatively to the valve D, so that iu the vibrations of said valve upon its axis of oscillation d', the lower ends of the wings D D will alternately be brought into juxtaposition with the central projection c. The seed, in quantities as desired for each hill, isv nieasured and separatedl from the inass of seed in the box A by any suitable mechanism, operated also, generally, by the saine motive apparatus which propels the vibrating valve D, and in such manner that a charge of seed is delivered from the seed-box, and7 passing downward within the seed-tube, is received between the wings D D at each forward and return stroke of the valve D, the wings D D acting as deliectors to carry said charges of seed alternately to the incline grooves c e, at the lower ends of which it is retained by the tongue d, until said tongue is carried, by a return move of the valve D, to the opposite side ofthe tube C, when the charge of seed will drop to the furrow prepared for its reception, in view of the operator, who may thus know whenv the droppin devices are operating, and avoid the possibility of passing along without planting.

Having now described the manner in which my invention :may be carried into effect7 what I desire to secure by Letters Patentis- The vibrating seed-valve D, having wings D D', arranged to operate with the fixed iuclines c e, substantially as and for the purpose specified.
