IMPROVEMENT I N CORN-PLANTERS.

Specification forming part of Letters Patent No. 223,069, dated December 30, 1879; application filed February 14, 1879.

To all whom it may concern.-

Be it known that I, FLAVIUS W. SHELLA- BARGER, of the county of Miami, in the State of Ohio, have invented certain Improvements in Corn-Planters, of which the following is a clear, concise, full, and exact specification.

My invention relates to improvements on my corn-planter which was patented April 24, 1877, and further and more perfected improve ments upon my corn-planter on which a caveat was tiled in February, 1877, and renewed in February, 1878.

These improvements consist in a change in the zigzag movement, the location in the pivotbolt being changed from the middle of the main cross-bar to a point to the left of the middle, between it and the seed-box on that side, the pivot-bolt connecting the left hound with the main crossbar.

The double-cranked rock-shaft, by which the zigzag movement was made through its connection with the main cross-bar, is dispensed with, and a simple hand-lever, pivoted to the outside of the right hound, (having a latch-rod,) substituted therefor. This leveris pivoted over an inverted semicircular rack, and has its lower end connected by a link or rod with the cross-bar near the right end.

By this arrangement the machine is much simplified and a greater range of movement on the right side effected, that runner being most required in advance of the other, as the left or near side of the team is most generally driven on the higher side around or across a hill-side in planting.

Another improvement is in making the seedboxes detachable entire, so that they can be taken off without the use of any tool and inserted, with the corn in them, for the purpose of removing and changing the seed-plate without being required to take the corn out of the seed-box.

The shoe-post is also provided with an adjustable roller or wheel gage, attached near drawings, two sheets, accompanying this specification.

Figure 1 is a side elevation of acorn-planter wit-h my improvements applied thereto. Fig. 2 is a plan view ofthe same. Fig. 3 is a view of the right shoe-post and a section of the furrowingshoe. A section is shown broken out of the shoe-post to exhibit the inclined plate f, from which the corn is deflected into the furrow when dropped. Fig. at is a rear view of the shoe-post with a section of the crossbar and also the lower plate of the seedbox attached. Fig. 5 is a plan view of the interior of the seed-box as detached. Fig. 6 is a bottom view of the same, showing the cap G, which confines the droppeeplate (Z to the under side of the bottom plate, I), so that it can be taken off with the box. Fig. 7 is a side elevation or edge view of the bottom plate, I), the dropper-plated, and the cap 0 enlarged.

My corn-planter is made in two'sections, flexibly connected together, the device for connecting the two sections being the same as described and claimed in my previous patent of April 24, 1877, consisting of a round T- shaped bar swiveled at the front end of coupling-bar (l. Foot-levers f, for raising the front section,instead of being pivoted upon the axle are pivoted upon the ends of a metal bar, 6,

which is bolted across the coupling-bar G some distance forward of the axle, and nearly mid way between the latter and the main cross bar B, on which the seed-boxes are supported. The ends of the bar 0" are bent upward somewhat above the plane of the coupling-bar to elevate the front ends of the foot-levers f so that their rear ends are lowest, this position better adapting them for being operated by the feet of the driver. I In order to strengthen the supporting-bar e at the point where they are pivoted, a brace, 0, extends from it to the axle, being firmly bolted to the bar 0 under the pivot-bolt of the lever, thus dividing the support between the coupling-bar and the axle, relieving the former of a large portion of the weight of the front section when raised by the foot-levers f. A bar or link-rod, u, connects the front ends of these foot-levers with staples u on the hounds g 9, near the main cross-bar B, thus bringing the points of (flexible) connection u and 'v nearer together than usual, the object being to allow greater freedom to the front section in its undulatory movements. and making the planter much easier handled by the operator.

Instead of the rigid forked tongue shown in my former patent, the hounds g g are separate from the tongue, which is bolted to the plate 70, which connects the frontends of the hounds. The rear ends of the hounds are connected by the long bar 0, which is also turned up at an angle near the ends and bent to a slight curve to form the foot-pieces for forcing the runners S into the ground.

A portion of the bar which supports the seat of the driver is shown in Fig. 1 resting on the coupling-bar C.

In this corn-planter it will be seen that there are no draft-rods, and that the front cross-bar, h, connecting the points of the shoes,'is not centrally pivoted at all. The shoe-post D is pivoted to the main crossbar, and the points of the furrowing-shoes are also pivoted to the bar h, as shown in my former patent, but the main pivot for the front section is by the bolt P through the left hound and the bar B, as seen in Fig. 2. This allows the bar B to be moved horizontally to an angle with its right line, as indicated by the dotted lines 12/ n.

It will be noticed that by the removal of the pivot from the center of B to the point shown the long end of this bar can be thrown to a greater distance either forward or backward, the long stirrups or loopsl l, which confine the two cross-bars, having sufficient space in their openings each side of the bars to allow this movement. The hand-lever a, by which it is accomplished, is pivoted on the outside of the quadrant-shaped rack-plate m at the top, the notches for its latch rod being on the lower edge. This plate is attached on the outside of the righthound alittle distance behind the main cross-bar, so as to have the hand-lever within easy reach of the operator. The rod n connects the lower end of the hand-lever a with the cross-bar B by a flexible attachment, 2. hole being made through the end of a and the rod hooked into it.

Fig. 2 shows the seed-box on the right removed and the lower plate, I), fastened to the main cross-bar by screw-bolts. This plate is cut out (see 19, Fig. 2) to allow the cap-plate G to fit into itwhen the box is secured in its position, this cap covering the seed-plate d, the angles of which can be seen projecting from under the cap in the enlarged view of the bottom of the seed-box a in Fig. 6. This figure shows the second bottom-plate, b, which is fastened to the seed-box a and forms its bottom proper. Its interior or top view is shown in Fig. 5. Bottom 1) is provided with a segmentshaped slot in it, so as to expose four or five holes or cells in the disk (I. On its under side, in the center thereof, is a stud or journal, t", cast on it. (See also Fig. 7.) Over this the seed'plate d, which is of the ordinary round form with teeth or lugs projecting from its edge, is placed, and the cap 0 secured over the seed-plate. The cap is cast with lugs 0 0 and e e on it, which turn down at an angle with its surface, and the larger lugs c c are bent out horizontally on the surface of the bottom plate, I) projecting far enough to pass under the raised lugs i, the cap being rotated in the direction of the arrows shown in the view, Fig. 6, thus effectually securing the seedplate and cap in place.

The bottom plate, I), is provided with lugs Z Z, which are slipped into slots out in the front edges of the lugs j, which are formed on the front and rear flanges of the plate I) on the cross-bar. (See Figs. 2, 3, 4, and 6.) After the seed-box is put in its place, inside the turned-up edge flange on b, it is secured by the ring or hasp c, which is formed like a trunk-handle, and is turned up over. the projecting lug b on the end of the bottom plate, 1).

Whenever it may be necessary to change the seed-plates and to:put in one with a greater or less number of holes, the seed-box can be readily detached by turning down the hasp c, as shown in Fig. l. The lugs g (seen on the sides of the bottom plate, 1),) fit into notches g in the fixed plate I).

It will be seen that the cap 0 is circular and is intended simply to retain the seed-plate d in its position on the bottom of the seed-box, so that the latter can beinverted and handled without its being detached, and to allow of the seed-plates being readily changed when required.

In the views,Figs. 3 and 4, the construction of the seed-tube of the runner or shoe-post D is seen. 0 e e are the transverse slots in the rear and lower part of the tube. These are made just wide enough to see the grains of corn as they pass them without allowing them to pass through them. They are not intend ed to allow the corn to be seen as it is held in the tube above the valve, but as it is in motion below it. f is a plate which is cast in the lower end of the seed-tube in the form of an inclined plane with its lower end toward the rear of the shoe-post. When the corn strikes this plateit is deflected or thrown rearward far enough behind the runner S to be plainly visible in the furrow before the wheel passes over and covers it. t is the tridentplate for operating the drop.

The attachment S consists of a shovel of bull-tongue shape, split about two-thirds of its length (through the middle) from the point. It is provided witha lug, 0, extending back from the rear side, by which it is fastened to the shoe after being set at the proper angle.

The roller 1 is pivoted in the end of a bracket or arm, 1*, which is grooved to slide on the fixed rib or guide 70, so that it can be adjusted in height or depth on it by set-screw S. Rib 7c is cast on the shoe-post.

I am aware of the rollers or gages shown in Patents No. 107,709, No. 127,648, and No.

156,924, and do not wish, therefore, to be understood as claiming the same.

I claim as my improvement- 1. In combination with hound g and main cross-bar B, pivot-bolt P, connecting the same, and allowing the right side of the front section of the planter to be thrown forward or backward to a greater distance than the left side, as and for the purpose hereinbefore set forth.

2. The main cross-bar B of a corn-planter, pivoted at a point between the center of the same and the seedbox on its end, so as to give to the long end of the bar a greater sweep, thereby allowing the furrowing-shoe on that side to be thrown farther in advance of or to the rear of the other than if the bar were centrally pivoted, as and for the purpose set forth.

3. In a corn-planter having its front and rear sections flexibly connected together, as herein described, hand-lever a, rack-plate m, hound g, link-rod n, and crossbar B, with thedropping devices and furrowing attachments connected therewith, as shown, in combination with a pivot-b0] t, P, connecting its opposite hound, g, with said cross-bar between the center and the seed-box a, on the same side, as and for the purpose set forth.

4. In a corn-planter having its front and rear sections flexibly connected together, as described, the combination of the supportingbar 6 upon bar 0, and braces 0, with the coupling-bar and axle, and the foot-lm ersj", forming a support for the fulcrum-point of the latter and dividing the weight of the front section, when raised, between the axle and couplingbar, all arranged as hereinbefore set forth.

5. In a corn-planter, the detachable seedboX a, constructed substantially as described, and adapted to be secured in position by plates and catches, as set forth, so as to be easily detached and inverted, with the corn in it, for the purpose of changing the seed-plates, as set forth.

6. In a corn-planter having a detachable seed box or boxes, the cap'plate G, in combination with seed-plate d and bottom plate, I), as and for the purpose shown and specified.

7. A seed-box for a corn-planter having a fixed bottom plate, I), a seed-plate, d, insertible under said fixed bottom plate and pivoted thereon, and a cap-plate, G, for retaining said seed-plate upon the bottom plate, substantially as shown, so that the box can be detached and inverted, without taking out the corn, for the purpose of changing the seed-plates.

8. The flanged open bottom plate, 1), provided with the slotted lugs j, notches g, and hasp c, as and for the purpose set forth.

9. A bottom plate, I), in a seed-box to a cornplauter, having the insertible lugs l, middle lugs, g, and end lug, b, or their equivalents, for connecting it by the slot-ted lugs j, notches g, and hasp c, or their equivalents, to the fixed bottom plate, I), on the cross-bar B, as hereinhefore specified, as and for the purpose set forth.

10. In a corn-planter, the adjustable rollerr, pivoted in arm 1', and the said arm 1" rendered adjustable upon the fixed rib or guide is, cast on the side of the shoe-post, and held in position, when adjusted, by set-screw S passed through slot, as shown, and for the purpose set forth.
