SEED-PLANTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 290,389, dated December 18, 1883,

Application filed August 16, 1883. (No model.) I

To all whom it may concern.-

Be it known that I, JONATHAN W. BRIG- HAM, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented' new and useful Improvements in Seed-Planting Machines, of which the following is aspecification.

This invention relates to that' portion of a seed-planting machine employed in the distribution of the seed, and of that class designed to deposit a grain at atime ina furrow prepared to receive it, or to deposit a grain at a time in a receptacle from which to be deposited in furrows in hills at proper intervals in proper quantities.

The object of this invention is to produce at a small cost a single-grain dropping-machine of a reliable construction and capable of use in perhaps all machines designed for depositing at proper intervals a single seed in drills, or a given quantity at proper intervals in hills, in line, or in check-rows. To this end I have designed, arranged, and constructed the seed- 2 5 distributing machines represented in the accompanying drawings, in which- Figure 1 is a plan view with lid or cover of seed-box removed. Fig. 2 is an elevation with one side of seedbox removed. Fig. 3 is a 0 transverse central section on dotted line 00 on Fig. 2. Fig. 4 is an isometrical representation of the slotted transverse vertical divisionwall in the seed-distributing compartment of the seed-box. Fig. 5 is a lengthwise vertical 3 5 section on dotted line g on Fig. 1. Fig. 6 is an isometrical representation of the fixed disk with its actuating-cams; and Fig. 7 is an isometrical representation of one of the pivoted seed-pickers. v

In the figures, A represents the sides; B, the ends; 0, a lengthwise division-wall; D, the

bottom; E, an inclined inner bottom, and F a slotted transverse vertical division wall. These several parts are suitably joined, pro- 5 ducing a seed-box having a seed-receptacle, H, with inclined bottom E. A chamber, I, from which the seed is distributed, and which chamber is connected with the seed-receptacle H by means of an opening, K, (represented in dotted lines in Fig. 2,) cut in the lengthwise vertical division-wall O, and an outlet-chamber, L, connected with the distributing-chamber I by means of the slot N, formed in the transverse wall F. This outlet-chamber is provided with an outlet-opening, P, out through the bottom E to permit the seed to drop from the chamber, all of which are substantially the same as the seed-boxes shown and described in Patent No. 208,885, dated October 15, 1878, issued to myself, Jonathan W. Brigham, and Theodore M. Flenniken, for improvement in corn-planters.

At R is represented a seed distributing wheel of disk form producedin parts, in which arepresents a disk recessed on one side, pro. ducing a peripheral rim, b, and its center is provided with an axial hub, c, centrally bored to receive an axial shaft. This disk is also provided at proper intervalswith studs d rising from its recessed face. I11 this disk-formed 7o distributing-wheel, 6 represents a disk fitted to receivethe hub c of the disk at and enter snugly within the peripheral rim b thereof and rest on the studs d, to which it is fixed by means of suitable screws, producing a wheel of disk form having an internal chamber, h, between the two disks. The peripheral rim b of this seed-distributing wheel is provided at proper intervals with openings t cut through the rim, having end walls of curved 'form produced from the centers 70 within the rim, and these openings communicate with the internal chamber of the wheel, and the portions of the rim between the openings cut therein are beveled on each side, as represented at l. The recessed disk a of the seed-distributing wheel is provided with segmental slot-openings on having their curved side walls produced from the centers is. The seed-distributing wheel is provided at proper intervals with a seed-pick- 9o ing device of the form represented in the drawings, consisting of a segment-arm, n, and aradialarm, it, having a thickness slightly less than the depth of the internal chamber of the seed-distributing wheel. The end of the ra- 5 dial arm a is pivoted within the chamber of the wheel on the center k, near its peripheral rim, in which position the outer portion of the segment arms n enter the openings 1' in the rim of the wheel in a free manner to I00 permit of a free oscillatory movement therein. The extreme outer end of the segment-arm at a is enlarged in thickness, and is provided at n with a beak, which overlaps the peripheral rim of the wheel, and its inner face in the angle formed with the segment arm is concave to receive the seed between the inner face of the beak and the outer or peripheral face of the wheel. This seedpieker, at the IO junction of the segment and radial arm in the inner angle formed thereby, is provided with a stud-arm, 0, projecting at a right angle with the side face of the arms and in such position that when the picker isin place. the stud-arm 0 will extend through the segment-slot openings m in the disk.

At T is represented a disk-cam, provided with a central hub, 12, bored to receive a shaft to revolve therein. This disk is provided with a controlling guide-rim, p, projecting from its face side concentric to the axis of the disk, and in position thereon to receive the projecting stud-arms 0 of the pickers to limit their outward movement.

At p is represented an irregular cam-rim projecting from the face of the disk eccentric to its axis, and in position on the disk to receive the stud-arms 0 of the pickers in the rotations of the wheel to project the pickers to discharge the seed.

At 8 is represented a curved lever, having a free pivotal connection at s with the disk at its upper side in such a manner as to permit of a limited movement about its pivotal support, and in such position on the disk that its inner curved surface will engage the studarms 0 of the pickers when in their rotations they leave the concentric guide-rimp, and operate by the action of gravity to press inward on the stud-arms and hold the pickers inward to grip and hold the seed. This disk-cam with its cam and guides is fixed in position in the seed-distributing chamber of the seed-box to the vertical side of the central lengthwise division-wall.

At T is represented a shaft having its bearing-supports in the hub of the disk, and in the walls of the seed-box. On this shaft, within the seed-distributing chamber of the seed-box, the seed distributing-wheel is mounted to revolve therewith in such posit-ion that its periphery shall extend through the slot N in the vertical division-wall 1*, and in its revolutions the stud-arms 0 of the pickers shall engage the guide and cam rims and the weighted le ver in such a manner that the seed-pickers in descending and passing through the seed contained in the chamber shall be limited in their openings to receive the seed properly, and in rising therefrom shall engage the weighted lever to cause the pickers to grip and hold the seed in its upward and over movement, and in its descent the stud-arms shall engage the irregular eccentric cam-rim to extend the pickers, causing them to open sufficient to discharge the seed and deposit it in the outlet-chamber, from which it descends through the outlet-opening to .the ground in drills, or otherwise caused to be deposited in hills.

It will be noticed that the construction of the seed-pickers and their pivotal connection with the seed-wheel are such that, in the revolutions of the wheel, the action of gravity will tend to open the pickers to receive the seed in their passage through the lower portion of their revolutions, and through the upper portion thereof the action of gravity will tend to close the pickers, causing them to grip and hold the seed. By this construction, in connection with the guide and cam rims and pivoted lever, I am enabled to produce a reliable and efhcient seeding device at a small cost.

I claim as my invention- 1. A seed-picker, substantially as herein described, consisting of the radial and segment arms with seedpicking beak attached, as and for the purpose set forth.

2. The combination, with a recessed or chambered seed-distributing wheel, of a seedpicking device, substantially as herein described, said seed-picking device having a pivotal connection within the chambered wheel, and a seed picking and holding beak to grasp, hold, and deliver the seed, substantially in the manner and for the purpose set forth.

3. The combination, with the seed-picking device having a pivotal connection with the seed-distributing wheel, of a guide to limit the opening of the beak of the seed-picker, substantially as and for the purpose set forth.

4. The combination, with the seed-picking device having a pivotal connection with the seed-distributing wheel, of an eccentric cam to open the beak of the seed-picking device to discharge the seed contained in the beak, substantially as and for the purpose set forth.

5. The combination, with the seed-picking device having a pivotal connection with the seeddistributing wheel, of a pivoted lever to engage the seed-picking device to hold the seed within the grasp of the beak, substantially as and for the purpose set forth.

(5. The combination, with a seed-box, consisting of a seed-receptacle, a seed-distributing chamber, and an outlet-chamber, ot'the hereindescribed seed-distributing wheel mounted to revolve within the distributing-chamber in contact with the seed contained therein, said seed-distributing wheel having means, substantially as shown, adapted to pick up and deposit the seed in the outlet-chamber, substantially as and for the purpose set forth.
