SEED-PLANTER.

SPECIFICATION forming part of Letters Patent No. 258,671, dated May 30, 1882, Application filed October 15, 1881. (No model.)

To all whom it may concern:

Be it known that I, LUTHER E. PORTER, of St. Cloud, in the county ofStearns and State of Minnesota,have invented certain new and useful Improvements in Seed-Planters; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and use the same, reference to beinghad to theaccompanyingdrawings,which form a part of this specification.

In the drawings, Figure 1 is a plan view; Fig. 2, a side view Fig. 3, a detail-view ofthe swinging arm or bracket; Fig. 4, a detail View representing the hub of the seeding-cylinder; Fig. 5, a vertical longitudinal sectional view; Fig. 6, a front detail view of the seed-cup and seeding-cylinder; and Fig. 7, a cross-section on the line or as, Fig. 6-

The object of this invention is to produce a simple, durable, and efficient broadcast-seeding machine.

Referring by letter to the drawings, A dosignates a portion of the main frame of the machine; and B is the axle, which isjournaled in a bracket, 0, secured to the frame.

0 isa gear-wheel fixed on axle B,and adapted to intermesh with a larger gear-wheel, D, mounted on the side of a swinging bracket, L,

which is hung upon the axle c of the rotary seeding-cylinder by means ofa hooked or semicircular-shaped recess, 6, at its upper end. The gear-wheel D is adapted to mesh with a gear-wheel, F, secured upon the axle e, and

thus motion is transmitted from the axle B to rotate the axle or shaft of the seeding-cylinder.

a G is a lifting-pawl pivoted at the side of the main frame, one arm of' which, g, engages a semicircular recess, 6 in the free or lower end 40 of the lifting-bracket E. Its remaining arm, 9, is provided with a series of perforations, 9 in any one of which engages the lower end of a lifting-rod, H, the upper end of said rod being adjusted in a casting, h, secured to one end 5 of the transverse eccentric shaft H, with which the rear ends of the drag -bars (not shown) are suitably connected. The eccentricshaft H is journaled at its ends, the casting It being provided with a journal, h, having its bearing in a bracket, 7L2, secured to the main frame, so that itforms the bearing for one end of the eccentric-shaft. The vibrations ofthe latter, which may be effected by any suitable lever or other mechanism, will actuate the lifting-rod H and pawl G, so that the latter will raise the bracket E,thus disengaging the gearwheel D from the gear upon the axle of the machine. A stop, h may be secured to the main frame in a position to limit the downward swing or vibration of the eccentric-shaft H.

I designates a vertical end bracket secured to the frame A, and providing supports for the bearings of the seeding cylinder shaft. This bracket is formed with angular corner pieces, i i, which receive the ends of the transverse inclined bars K K, that form the sides of the hopper.

k is a cast-metal yoke depending from the bracket I and forming a bearing for the seeding-cylinder shaft. 7o

Ldenotes the seed-cup, which is composed of two parts, one forming the body of the cup and the other the side cap or plate, M, which is secured by bolts or screws to the body. The latter is formed ofasingle casting, having upper flanges, Z l, for securing it to cross pieces or bars K K, the inclined convergent side walls, Z, and inclined curved front wall, l extending to the delivery spout or tube i Inside the seed-cup is provided a partition, Z consisting of the inclined way i and semicircular or curved bottom 1 between which latter and the arched casting l in the top of the seed-cup the seeding-cylinder rotates and reciprocates. 8 5

N is the seeding-cylinder, arranged to slide on the square axle or shaft 6, and formed with a plain cylindrical surface, a, for a portion of its length and a longitudinally fluted or corrugated surface, 72, for the balance of its length. 0 Inside the seeding-cylinder is arranged a hub,

0, consisting of a casting having a square cen tralopening,0, through which the shaft 6 passes, and radial arms 0, secured to the interior sides or wall of the seeding-cylinder. The hub 0 not only forms a bearing or support for the shaft 6, but it also strengthens the cylinder, and is cast integral therewith, and the sides 0t its central opening may be inclined or beveled, as shown at o in Fig. 5 of the drawings, for purposes of greater strength and durability. At the smooth or plain surface end of the seeding-cylinder is formed an annular groove, P, which receives the curved ends or arms Q, of a bifurcated plate, Q, that is adjustably secured upon ahorizontal rod, R, arranged to slide in bearings formedin the seed-cup, and provided with a stop pin or stud, r, engaging the projecting upper edge, a", of the plate M.

S is a hand-lever, pivoted to the under side of one of the bars K, and provided with a longitudinal slot, 8 through which the pivot-pin passes, to admitot' the free vibratory movement ofthe lever. The engaging end S of thelever is forked or provided with a series of prongs, s, which are adjusted on the rod R between its upturned end '1 and the end of plate 0. By means of this construction, when the lever is operated in different directions the rod It, on which is secured the plate Q, will he slid horizontally on its hearings in the seed-cup, and the plate Q will cause the smooth or corrugated surfaces of the seeding-cylinder to be brought within the seed-cup, as may be desired.

T isadogor latch pivoted on the main frame, and adapted to be swung under the bracket E when the latter is raised and it is desired to keep it in this position.

The operation of my invention is as follows: The lever S is operated to bring the corrugated or fluted portion of the seeding-cylinder within the seed-cup, when, by the rotation of the cylinder communicated from the axle B by the cogs O, D, and F, the seed is fed through the seed-cup down the curved way Z and out at the delivery-spout. To stop the flow of the seed it is only necessary to operate the lever S to bring the plain portion of the cylinder within the seed-cup, and the seeding mechanism may be readily thrown out of gear with the gearwheel C on the axle B by vibrating the eccentric-shaft H.

I am aware that it is not new to provide means for lifting the seeding gear out of engagement with that on the axle, and such I do not claim broadly as my invention, which consists in the herein'described improved arrangement, construction, and combination of parts.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States- As an improvement in seed-planters, the combination of the gear-wheel O on the main axle B, the swinging bracket E, carrying the gearwheel D, and having a hooked or semicircular recess, 0, at its upper end, by which it is hooked or hung upon the axle c of the seeding-cylinder, and a semicircular recess, 0 in its free lower end, the lifting-pawl Gr, pivoted at the side of the frame, the upper arm of which, g, engages the recess 0 of bracket E, and having its lower arm, 9, provided with a series of perforations, g and the lifting-rod H, the lower end of which engages the perforations 9 while its upper end is adjusted in a casting,h, on the eccentric-shaft H, all arranged and operating substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

LUTHER E. PORTER.
