USRE3388E - Improvement in corn-planters - Google Patents

Description

UNITED* STATES To all whom it lmay concern Be it known that. I, JARvIs CASE, of LaA Fayette, county of Tippecanoe, and State of Indiana, have invented certain new and useful Improvements in` Corn-Planters; and I .hereby declare that the following is a clear, i'ull, und exact description thereof, reference being had to the accompanying drawings, making part of this specification, like letters indicating like parts wherever they occur.

My invention relates to that class of agricultural implements denominated corn-planters; and the invention consists in certain novel features and combinations ot' devices, whereby I am enabled to produce avery perfcc-t machine, as hereinafter explained.

Figure l is a perspective view of my improved machine complete. Fig. 2 is a longi- .tudinal vertical section of the same. Fig. 3

' is a transverse vertical section near the rear end, and Fig. 4 a longitudinal vertical section through the center of one ot' the runners.

I construct my machine with a frame con-A sisting of a series oflongitudinal bars, A, connected by cross-bars B, the front end resting on a pair of runners, D, and having a pair of wheels, C, located behind the runners. The

frame thus made'is rigid from end to end, andA has located upon its front portion, over the rear portion ot' the runners D, a couple of seedboppers, I, behind which I arrange lengthwise of the machine a seat, EI, for the opera tor, as shown in Figs. l and 3, the front end ofthe seat being supported on two upright pieces, G, as shown in Fig. l.

The tongueE is pivoted to the front cross- 1 -bar B- by means of two uprightplates or pieces,

F, through which and the tongue a holt, a,

`passes transversely, as represented in Figs.'1

and 2, the rear end of the tongue extending .back between the uprights G, which support thefront end ofthe seat, as shown in Fig. '2.

To the rear end ot' the tongue I attach a cord, c, and pass it up through a hole in the seat, and tothe upper end ot' the cord c, above theseat El, I secure a short -rod or bar, b, which rests transversely on the seat, and prevents the cord c from dropping down out of the hole. By pulling upon this cord c the rear end of the tongue E is raised, and as its front end is PATENT' OFFICE.

IMPROVEMIYENT IN CORN-PLANTERS.

Specitlcation 'forming part of Letters Patent No. 18,730, dated December 1, 1857; Reissue No. 3,388, dated April 20, 186er.

position, and as the front end of the machine is pivoted to the tongue by the pin a the runners D and front portion of the machine will also be raised clear of the ground, as indicated by the red lines in Fig. 2, the tongue thus forming a lever ofthe second order. In order to hold the machine in this position it is only necessary to shove the bar b forward and secure it in a notch in the front of the uprights Gr, as shown in red in Fig. 2. By releasing it from this notch the rear end ot' the tongue is lowered, thereby letting' the runners down upon the ground again.

Through each ofthe hoppers I there extends a seed-slide, J, having two seed-cells, e, ot' proper size to hold the required quantity ot' grain fora hill. These slides are placed so as to move lengthwise ofthe machine, and have their front ends protruding from the front side of the hoppers, as shown in Figs. 1aud4.

A rock-shaft, K, is journaled iu the runners, just infront ofthe hoppers, and has secured to it near each end a rod or arm, f, which works in a mortise or slot cut in the runner D, and extends up to and engages in a hole in the front end of the slides J, so that as the rock-shaft K is operated the slides J are moved back and forth.

In order to give motion to the rock-shaft and the slides, I provide two means-one for f operating it by the foot and the other/by thel hand. The iirst consists ot a lever, L, fulcrumed on'a cross-bar between the rear ends ot' the runners, and connecting at its front end by a staple or pin, o, with the rock-shaft K, as represented in Fig. 2. By placing his foot on this lever L lthe operator can move the slides by simply rocking his foot forward or back, a hill or quantity ot' seed being deposited at each movement.

The hand apparatus consists simply ofa handle, M, which vis pivoted by a staple to the rockshaft K, as represented in Figs. l and 2. alternately pullingand pushing this handle the rock-shaft and seed-slides are also operated the same as when the foot-lever or treadle L is operated.

In the rear portion of each runner D,`and directly under the hopper, there is formed a vertical channel or seed-duct, d, and in this chanheld by the neck-yoke of the team in a txed nel I locate a pivoted valve, g, its upper end 2 asse entering a hole or recess in the slide J, so that as the latter is moved to and fro the valve gis also moved, its motions being in line with the length of the runner, as shown clearly in Fig. 4, the operation being to drop a hill of seed from the lower valve, g, to the ground, and also another charge or hill of seed from the hopper I down to the valve g at each movement to or fro.

In order to scatter the seed in the furrow and prevent the stalks from growing in a compact or crowdedV state, I/place tirst below the mouth of the seed-duct d a-scatterer, kn, as represented in Fig. 4.. This scatterer may consist of a pin or stick projecting longitudinally across the mouth of the duct d or a little below it, so that as the corn falls from the valve git will hit upon this pin or stick a, and thus be scattered or spread more `or less in hill.

For the purpose of furnishing a means of marking the ground at the same time the` planting is done and to keep the rows uniform and equidistant, I provide the machine `with a marker, which Ilocate at the rear end ot' the machine, so that the operator can reverse it or throw it into or out of operation at pleasure.

This marker consists of an oblong rounded piece of plank, P, attached to the end of an arm or rod, N, which has itsinner endpivoted at the center of the rear end, as represented at h, Fig. 3, it being so arranged thatv when the part P rests upon the ground lthe arm N' shall clear the frame of the 1nachine,`so as to permit the machine to rise or fall without interfering with the operation of or raising the part P from the ground.

In the arm N a. short bar or piece, O, is pivo'ted at a point directly over the frame, in rear of the wheel, as shown in Figs. 1 and 3, there being a hole, t', in the frame at that point on each side, as shown in Fig. 3. hen it is desired that the marker shall not operate, as in turning at the ends, it is raised up, and the end ofthe piece is permitted to rest on theframe, thus holdi-ng the marker up off the ground, as shown in red in Fig. 3; but when it is desired to have the marker operate, the lower end of the pivoted piece 0 is dropped into the hole iin theframe, as represented on the righthand part of Fig. 3, the piece O thus serving the twofoldpurpose of supporting the marker when raised and also of preventingit from being wrenched loose from its pivot h.

The piece P is secured to the arm N in an oblique position, so that while it may be as lightlas possible it shall make a mark suiciently large and plain to be readily scen. The distance between the piece P and the seedduct nearest to it should be exactly equal to the distance .that the seed-ducts are apart from each other, so that one of the runners D should always follow in the groove or mark made by the marker.

For the purpose ot' indicating to the operator the exact time when he should operate the slides, l attach to the cross-bar on which the lever L rests one or more projecting curved pieces, m, as shown in Figs. 2 and 3, which serve as indicators. The operator upon the lseat H, by looking at these points m, can see when the machine is in line with the rows or hills previously planted, and is thus notified that it is time to operate the slides, the indicators m being placed a little in advance of the seed-ducts, so as to give a suicient time for the seed to drop and reach the ground bythe time the machine-which, of course, is constantly moving forward-has arrived at the proper position to deliver the seed exactly in line with the hills previously planted. The runners make the fnrrows for receiving the seed and the wheels G crowd the earth down into furrow after the seed is deposited, and thus cover it, as is usual in this class 0f machines. f

I do not claim broadly thc use of a runner for opening `a furrow and supp'orting a seedhopper, as that has been long known and used, as in the seed-planter of Henry Todd, patented December `15, 1843, and also in the English Patent No. 8,281, to Richard Hornsby, November 25, 1839; but,

`Having-thus described my invention, what I claim isl. The runners D, in combination with the valves g and the spreaders n, arranged to operate substantially as described.

2. The combination of the hoppers with the slides J, the seed-ducts with their valves g, and

-the spreaders a, arranged to operate substantially as set forth.

3. The combination, in a corn-planter, of the `seat H, located in rear of the hoppers, the `slides J, operated by the handle M, and rockshaft K and the valves g, substantially as herein-described.

4. The combination of the runner D, seedducts d, and spreader n, when arranged to operate substantially as described.

5. The combination of the rock-shaft K, with its arms f-and treadle or foot-lever L, for operating the mecd-slides, substantially as described.

6. So combining with the operator-s seat H a marker having in its arm a hinged brace or its equivalent as that the operator may from lhis seat turn over or reverse said marker,

suspend it upon the machine while turning around, and drop it into its working position without leaving his Seaton the machine, as herein set forth. v

7. The combination ot" the seat H, lever M,

slides J, valves g, and runners D, when arranged to operate substantially as described.

8. The combination of the seat H, lever M,

slides J, valves g, spreaders n, and runners D,

arranged to operate substantially as described.
