IMPROVEMENT IN WHEAT-DRILLS.

A Specilication forming part oi'Lctters Patent No. 59,595, dated November 13, 1366; Reissue Xo. 3,626, dated August 31, 1869.

To all whom, it may concern:

Be it known that I, JAMES F. HARCOURT, of Moscow, Bush county, Indiana, have invented a new and Improved VVheat-Drill; and I do hereby declare that the following is a full, clear, and exact'description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, making part of this speciiication, in whichl Figure lis a side view of my invention. Fig. 2 is a vertical longitudinal section taken in the line a' Fig. 3. Fig. 3 is a plan or top view of the saine. Fig. 4 is a detached view ot'a seed-distributing wheel pertaining to the same.

Similar letters of reference indicate like parts.

This invention relates to a new and improved device for sowing wheat and other grain in drills; and it consists in a novel construction and arrangement of parts, as hereinafter fully shown and described, whereby a very simple and efficient implement for the purpose is obtained, one which may be turned within a limited compass, and which will admit of having the seed planted at a greater or less depth, as may be desired.

A represents the frame ofthe machine, composed of two bars, a a, arranged in V form, and connected by a cross-bar, b. The rear ends of bars a a are attached to standards c c, slightly inclined, and the front part of bars a a have the lower ends of the handles d d bolted to them, the rear parts of said handles being connected by a screw-rod, e, with the upper ends of the standards c c. A standard, f, is tted on the cross-bar b of the frame A and is braced by a rod, g, the lower ends of the standards c c being braced by rods h. The standard f is in front of the standardscc, and in line with the center of the space between said standards.

B represents a wheel, the shaft C of which has its bearings in the rear parts of the arms t' z', the front ends of which are fitted on the ends of the cross-bar l), or on bolts passing into the ends of the same. The shaft C is at the rear of the standards c c, and said shaft and wheel may-be adjusted higher and lower 'by adjusting the rear parts of the arms t' 'i higher or lower, pins j passing through oblong slots in the arms into any one of the series of holes in the standards c c. The wheel B is placed to the rear of and directly in line with the standardf, so as to follow in the track of the share at the lower end of the samethe said share pushing aside stones and clods which would otherwise interfere with the wheel and cause irregularity in the rotation of the seed-shaft, and in the depth penetrated by the shaves. The standards c c f have each a seed-conveying tube, D, attached to their rear sides through which the seed discharged from the hopper E drops into the furrows, the latter being made by shares k attached to the lower ends of the standards, and it will be-seen that the depth of the furrows may be regulated by adjusting the wheel B higher or lower. The hopper E is iitted on the rear end of the frame A, and is provided with a concave bottom, Z, having the openings m made in it, said openings being directly over wheels n on a shaft, o, underneath the bottom Z. The f wheels a are provided at their peripher'ies with teeth 1J, (see Figs. 2 and 4,) and these wheels discharge the seed from the hopper7 the shaft o being rotated by gears r from the shaft C, as shown clearly in Fig. l. The central wheel, a, discharges the seed directly into the tube D of the front standard, f; but the other two wheels discharge the seed into tubes S, which lead into the tubes D of the standards c c, traversing or partially traversing holes or mortises in the said standards, and by thus connecting the frame A (to which their upper ends are attached) with the stand- `ards from sidebraces for the latter. The wheels a work or rotate within small boxes or :in-`

closures t, each of which is provided with an elastic or yielding plate, u, at its bottom, by raising or lowering which the discharge of seed may be graduated as desired, said plates being adj usted by arms c, which project froma shaft, w, the latter being turned through the medium of an index-arm, a', at the outer side of the hopper. (See Figs. l and 3.)

' If necessary or desired, cut-oifs F may be fitted within the hopper, so that seed may be discharged from two or onel only of the holes or openings m whenever required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent--L l. The concave bottom Z, in hopper E, provided with the holes or openings m, in oom bination with the toothed Wheels n, fitted in inclosures t, underneath the bottom l, the yielding` plates u', and arms o, attached to shaft w, for adjusting the plates u, substantially as and for the purpose set forth.

2. The pivoted standard c, in combination with the slotted arm i., bearing the shaft C, substantially as described, for the purpose specified.

3. The adjustable yielding plate u, in cour bination with arms fu, shaft w, and index-arm a', substantially as described7 for the purpose specified.

4. The arrangement of the adjusting-Wheel B in line with and in rear of the central stand ard f, as and for the purpose stated.

JAMES F. HARCOURT.
