DIVISION A.

To all whom it may concern Be it known that I, Gnoaen 1). HAWORTH,

of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Corn-Planters, of which the following is a full, clear, and exact description, reference being had to the 'accompany ing drawings, making part of this specifica tion, in which- Figure 1 represents avertical longitudinal section through my improved machine, taken on the line a; at, Fig. 2; and Fig. 2 is a plan view of the same. Fig. 3 is a plan view of the pulley holder and pulley, and Fig. at is a side elevation of the same. Fig. 5 is a rear Fig. 6 is a vertical section through said devices on the line 3 y, Fig.5; and Fig. 7 is a transverse section taken on the line 2 2.

Similar letters of reference denote corresponding parts wherever used.

My invention consists, first, in a novel arrangement of parts, adapting the seeding attachment to always maintain a horizontal position, notwithstanding the irregularities in the surface of the ground over which .the machine is drawn; second, in an arrangement of vibrating seat-standard and connecting rod or lever, in combination with the seeding devices, for raising and holding the latter up above the ground,or for depressing them into working position third, in novel devices for facilitating the passage of the corn to and the scattering of the same upon the ground; fourth, in combining the devices of both the upper and lower seed-drops with the actuating-cord, in such manner as to cause the latter to impart a positive movement in both directions to said dropping devices; and, fifth,- in a novel construction of pulley-holder, whereby it is adapted to revolve back and forth through halt a circle, obviating the necessity of removing the check-row cord in turning the machine, said pulley-holder being an improvement on that embraced in Letters Patent granted to me February 22, 1870, No. 100,032.

In the accompanying drawings, A A represent two longitudinal frame-bars mounted up on and secured to the main drive-wheel axle c, and supporting the seeding parts of the machine. 15 is the pole or tongue, pivoted at its rear end on a rod passing through the bars A A. In advance of the pivot ot' the tongue is a shoe or socket-plate, (3, provided with vertical flanges, which embrace the tongue between them, while allowing free vertical and longitudinal play of the tongue and shoe relative to each other. The forward end of this shoe is suspended from the tongue by a vibrating link, a, and to its lower free is secured a bent transverse bar, D, Whic is pivoted in suitable bearings on-the lower faces of the bars A A. The outer ends of this bar D curve downward andto the rear, and have the forward ends of the furrow-shares G G pivot-ed thereon, as shown. The forked rear ends of these furrow shares have grooved seeding tubes or standards G G secured to them, which, at their upper ends, are connect ed by a transverse bar, E, at or near midway of the length of which is secured a flanged bracket, 6, to the vertical flanges of which the rear lower ends of links or straps d d are pivoted, the forwardends of said links being pivoted to the transverse rod forming the touguepivot.

The seeding hoppers F and the seed discharging devices are connected with the bar E, and the latter being connected with'the frame-bars A. by means of pivoted bent bar D and link at, which act like the links of a parallel rule, the horizontal position of the seeding attachment will be preserved in rising and falling to conform to the uneven surface of the ground over which the machine is drawn.

H is a seat-standard, forked or provided at its ends with angular straps, those at the up per end It clasping and being pivoted to the seat H, and those at the lower end h h be ing pivoted to the bars A A, as shown. The standard H is slotted at 71? to receiveone end of a bent bar, i, and is provided with a series of transverse 'iertorations, in any one of which said bar z may be pivoted for adjusting its throw, as desired. The lower end of the bent link or bari is pivoted to the rear end of a bar or lever, I, the forward end of which is pivoted in the bracket 0 on the bar E. The bar or lover I has its fulcrum in a vibrating shoe 1 on the main axle a. As the seat-standard is vibrated backward it acts through the link t and lever I to raise the furrmv-shares Gr outof the ground, and, when thrown sufl'iciently back, to place the pivotal connection of the link i, with the standard H, in rear of the pivotal connection of said link with bar or lever I, a lock is formed, holding the furrow-shares above the ground for transportation.

When the standard is thrown forward into the position shown in full lines, the weight of the driver is utilized for forcing the furrow shares into the ground, the position of the driver regulating the depth of the furrow; H is a link connecting the forward edge of seat H with the lever I, in advance of the seatstandard, and serving in connection therewith as a parallel link, for preserving the horizontal position of the seat when the standard H is vibrated. 7c is a vertical rock-shaft, arranged within the groove or concavity g of the standard G, and stepped in a shoulder or projection ,at the lower end of said standard, as

shown. The shaft 70 is made tapering toward its upper end, which is secured in a vibrating or rocking seedslide, N, to which motion is imparted by a reciprocating bar, 0. The slide is located between perforated plates n a, fOIIlling a double bottom to the grain-box, and adapting the slide to receive and discharge the corn. The shaft is near its lower end is provided upon its opposite sides or faces with sloping shoulders or inclines it, down which the corn descends to the rear, escaping through a slot or opening, at p, in a partial sleeve, P, covering the lower end of the shaft 70, as shown. By this arrangement, and the location of the discharge-openings in-the hopperbottom, the discharges of corn pass down alternately on opposite sides of the shaft is, and are held between the inclines p and sleeve P, near t e bottom of the furrow, until, by the reverse vibration of the inclines it after receiving their respective charges, they arebrought opposite the outlet 11, when the several grains roll in quick succession into the furrow, the tapering form of the slot 19, and the relation of the inclines k thereto, facilitating the proper scattering of the grain. The perforations in the bottom plate a of the grainbox F, and those in the vibrating plates or slides N, are so arranged that the latter receives a charge at each end of its throw, and discharges the same on the reverse throw. These slides N are operated by the reciprocating bar 0, which, midway of its length, is connected with a vibrating arm or lever, 0, attached to a rocking plate, 0 pivoted to the bar A, and operated by connecting-links from the forked levers L L, which vibrate in reverse directions, operated upon alternately by the knots or projections on the check-row cord M. By this arrangement, each knot in the cord is made to actuate both of the levers L L alternately, and thus, through the arrangement described, to vibrate the plates N N with a positive movement in both directions, causing a discharge of grain, at each throw, into the seed-channel g. and thence through the vibration of the rock-shaft it into the furrow, as described.

Q, represents one of the guiding-pulleys for the check row cord, pivoted between two plates, q q, and provided with shanks or semisleeves g, which clasp, and are free to turn upon, a horizontal pivot, r, on a verticallypivoted pulley-holder, 1t, mounted on the end of a transverse bar, A. A lower horizontal arm of the pulley-holder, resting'on the bar A, is forked or provided with spurs 1 r which, striking against a pin, 8, prevent the horizontal vibration of the pulley-holder beyond the two positions shown in Fig. 2, and the sleeve (1 has a flange formed upon one side, which rests upon a pin or stop, .9, adapting said sleeve with its plates q q and pulley Q to be turned over from one side to the other, but preventing it from dropping below a horizontal position. By this arrangement the necessity of removing the cord from the pulley when the machine is turned at the end of the field is obviated, it being necessary only to turn the pulley over, and to allow the pulley-holder to vibrate on its vertical pivot.

Having now described my improvements, what I claim as new, and desire to secure by Letters Patent, in this division, is-

l. The rocking bar D, pivoted to the horizontal bars A A, and the arms or links (1 (1, also pivoted to said bars, in ombiuation with the vibrating seeding attachment, for maintaining the horizontal position of the latter, as described.

2. The vibrating seatstandard H, lever D, and connecting bar or link i, in combination with the seeding attachment, substantially as described.

3. The shaft It, provided with the inclines is, arranged within the seeding tube or channel g, and operating relatively to the dischargeoutlet 19, substantially as described.

4, The combination of the shaft 70 and slide N, or equivalent devices, for producing the upper and lower drop of the grain, as described, with the actuating check-row cord through the connecting devices, substantially as described, whereby a positive movement in both directions is given to said dropping devices, substantially as and for the purpose set forth.

5. The semi-revolving pulley-holder, substantially as described, and for the purpose set forth.
