CHECK-ROW CO RN PLANTE R.

SPECIFICATION forming part of Letters Patent No. 271,167, dated January 23, 1883,

Application filed July 18, 1882. (No model.)

To all whom it may concern Be it known that I, JOHN K. Voonnnns, of Pella, in the county of Marion and State of Iowa, have invented a new and useful Improvement in Check-Row Corn-Planters, of which the following is a full, clear, and exact description.

The object of my invention is to provide a dropping attachment adapted to be applied to any form of check-row-planting machine, but more especially intended for'the class of planters shown and described in my Patent No.2l4,- 694, granted July 19, 1881, which will not offer so much resistance to the knotted wire or rope staked across the field as those in common use, and one which will therefore be made more durable and more efficient than those in common use.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the hoppers, cam-shaft, and dropping movement, the

shaft being provided at its ends with my sprocketwheels and pulley carrying yokes. Fig. 2 is aside elevation of one of the yokes, part being broken away to show the pulleys and sprooketwheels; and Fig. 3 is a sectional elevation, showing the cam and dropping movement.

A A representthe hoppers.

B represents the cam-shaft, (J the droppingplate; and a I) represent respectively the lever and connecting-rod, by which the droppingplate is reciprocated by the oppositely-inclined blades of the cam D, as fully shown and described in my above-mentioned patent.

Upon the ends of the shaft B are fixed the sprocket-wheels G G, the ends of the arms of which are slotted to form forks, as shown at 0, to receive the knotted rope or wire E, as shown in Fig. 2.

F F are the yokes, which are placed loosely upon the ends of the shaft B. They inclose the sprocket-wheels and are held in proper position by the armsff, reaching out from the shaft-supports G G, as clearly shown in Fig. 1.

At the ends of the yokes are formed the upwardly-projecting plates (1 d, the latter of which serve as guides to the wire or rope E as it passes between the plates and the guttered pulleys H, which are horizontally pivoted at the upper edge of the yokes upon the outwardly-projecting plates h. To the plates 5 d are pivoted the guttered pulleys J, which are held by their pivots a short distance above the guttered pulleys K,jourualed in the yokes,

as shown in the drawings.

To the under side of the yokes are secured 60 the springs L, which are adapted to bear upon thesprocketwheels, as shown clearly in Figs. 1 and 2.

The rocking hub N, through which the lever a passes, and in which it is held by the set- 6 screw 0, is of substantially the same construction, and is held in the perforated plate 0 and is adjustable in the several holes of the said plate, for regulating the movement ofthe dropping'-plate, in substantially the same manner as shown and described in'my original patent, above referred to.

In use the knotted rope or wire E, which is first properly staked across the field, is lifted up and placed between the pulleysJ K in the forks 0 of the sprocket-wheel, and between the pulley H and the projection 61, as shown in Fig.2. Thus arranged, upon moving the planter along the wire or rope, the knots or other obstructions thereof'being of sufficient size so So that they will not pass between the forks of: the sprocket-wheel, will cause it to be turned, which will partially rotate the shalt 1B, which will, through the dropping movement and cam, reciprocate the dro1 piug-plate and drop the hills. This movement will be repeated as each knot or other obstruction on the rope or wire passes the sprocket-wheel, the movement of the wheel being stopped at all other times by the spring L, which offers no resistance to 0 the movement of the machine while the corn is being dropped, as it serves only to stop the motion of the sprocket-wl1eel after one hill has been dropped, so that the cam will not turn on around and drop two hills at once. The pulleys also serve to greatly reduce the friction of the machine upon the wire or rope and to greatly increase the durability of the machine.

Having thus described myinvention,what I claim as new, and desire to secure by Letters Patent, is

end by a proj ectingarm, f, carryinga sprocketwheel between guide pulleys, and provided The combinatiomwith the shaft B,carryingwith springs L, as shown and described.

mm D for actuating the mechanism which 0p- 5 erates the drop-plate, of the yokes F F, arranged loosely upon the ends of said shaft, havin g vertical end plates, 11 d, supported at each JOHN K. VOORHEES. Witnesses:
