IMPRovEMENT IN CHECK-sonatas FoRcoeN-PLANTERS.

Specification forming part of Letters Patent No. 7,\liil0, dated February 20, 1877; application filed January 16, m77.

To all whom it may concern:

Be it known that I, ROBERT FAmEs, of Decatur, in the county of Macon and` State of Illinois, have invented certain new and useful Improvements in Check Bowers for Corn-` Planters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had Vto the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective view of a planter embodying my invention. Fig'."2 is a front elevation of the devices for operating the seedslides. Fig. 3 is a top view of the parts shown in Fig. 2. Fig. et is a detail View, hereinafter referred to. Fig. 5 is a perspective view ot' the mechanism for transmitting motion from the rock-shaft to the seed-slides. Fig. 6 is a similar view to Fig. 5. Fig. 7 is a sideeleva tion of one of the forked levers, and the end of the shaft on which it is mounted.

Thisinvention relates, generally, to that class of corn-planters in which the ordinary seedmeasuring and discharging mechanism is operated by devices intermediate between the seed-measuring mechanism and an actuating knotted wire or cord stretched across the field, and relates especially to improvements in said intermediate devices.

The invention consists in the use of a single Wiper to transmit motion from the rock-shaft alternately to two bell-crank levers. It also consists in the employment of a wiper carried on a rock-shaft for operating the seedslides, having a hinged plate. on its end, adapted to carry oneV of the tappets upon which it acts forward, and rise by swinging on the hinge, to allow it to return over the other tappet and intol position to act upon it at its next forward movement. It further consists in certain details of construction and arrangement, hereinafter referredto.

The same letter of reference indicates the same part in the different views of the drawlng. Y

Letter A represents the forward part or frame of a corn-planter, supported on runners A', and carrying the seed-boxesB E, mounted on the frame A, and containing the seed-cup slides, which are operated in both boxes, B, by a connecting-rod, a. C is the rear frame, mounted on wheels C', and carrying a drivers seat, c. Ihe foregoing parts represent an ordinary' corn-planter, which may be of any other construction, having two seedboxes with seed-measuring devices operatedby a connecting-rod. D is a bar, on which my improvements are mounted, and is itself mounted above the boxes B, transversely with the planter, and with its ends projecting somewhat beyond the seed-boxes B B. E is a rock-shaft, journaled in Vsuitable bearings to and parallel with the bar D. F F are levers, mounted, as hereinafter described, one on each endof the rock-shaft E, and their distal ends crotched or forked, as shown in the drawings. On the outer ends of the bar D are arms G,`carrying pulleys g g', the rear pulley g journaled between vertical arms g. rlhese pulleys gg and arms g serve as guides to direct and retain the wire or cord Hin proper contact with the forksin the levers F, as the machine is drawn forward beneath said cord, which is previously stretched across the field, and is provided with regularly-recurrn g knots or trippets k.` Midlength of the bar D is fixed a plate, I, with projecting arms 'i t', on the outer end of each of which is loosely fulcrumed at its apex a bell-crank lever, J, the rearwardly-projecting arms of which are seated loosely in holes in a link, K, which connects them, and is itself held by loops 7c, through which it may be longitudinally reciprocated. L isa lever, fulcrumed at l to a curved standard, M, which projects from the bar D, and has a slot in its upper end, whichl receives a stud, k', that projects from the link K.

The lower end of the lever L has a series of holes, l', which receive one end of a link, n, the other end of which is connected in any suitable manner with the bar a, which is the ordinary bar connecting the seed-slides of corn-planters. By adjusting the link n in the holes l', the device may be adjusted to planters having greater or less throw of the seedslides. The lever L may be connected at its lower end directly to the bar a by passing through a slot therein, or otherwise. P is an arm or tappet projecting from the rock-shaft E, and has a broadened plate, p, hinged to its outer end. Q is a weighted arm projecting from the shaft E, its descending movement limited by a shoulder, g, on its rear portion striking the bar D, and its ascending movement limited bya springplate, q', (see Fig. 4,) thus limiting` the oscillations ofthe rock-shaft E about its axis.

As the plantelI is drawn forward, With the cord H resting in the fork of one of the forwardlyinclined levers F, said lever Will be brought successionally into contact with the knots h, and will be, by reactionary l'orce, oscillated periodically rearward to an angle permitting the escape of the knot /L fromh forked lever. The oscillation ofthe lever F will oscillate the bar E,and raise the Weighted arms Q to the spring q', and When a knot, 7L, releases a lever, F, the bar E and lever F will be oscillated or returned to their original positions by means of the weighted arm Q.

In order to give the necessary sudden impulse to the-seed-slides, the levers F are mounted so as to oscillate through about onehalf of their arcs of motion before acting on the shaft E, which is accomplished, as shown at lfig. 7, by making the end of the shaft E rectangular in its cross-section, and seating it in an opening through the lever F, shaped as plainly shown at same figure, and from Which it Will be seen that the lever F may be oscillated from the full-line position to the dotted-line position F Without moving the shaft E, and that, in further moving it to the dotted-line position Ff, it will carry the rockshaft E with it. As the shaft E is oscillated by the lever F, it will oscillate the tappet P, and the plate p Will engage With an arm of one of the levers J, and carry it rearward, as

plainly shown at Figs. l, 3, and especially 6, thus reciprocating the link K, and oscillating the lever L, and operating the seed-slide bar a, in the obvious manner, and at the same time throwing the other bell-crank J into position, as shown at Figs. l and 7, to receive the next impulse of the same kind. As the tappet Pis thrown back toward its normal position by the Weighted arm Q, the vplate p, swingingon its hinge, Will pass over the noW intervening armj of the bell-crank lever, as shown by Fig. 5. This operation is repeated, the tappet P striking the bell-crank levers J alternately, and its movement of the one bringing the otherinto position for its action, as described.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. rlhe single Wiper or tappet P, combined Withvthe bell-crank levers J J and rock-shaft E, to transmit motion alternately to said bellcrank levers, substantially as described, and for the purpose specified.

2. The Wiper or tappet P, having a hinged,

plate, p, affixed to its distal end, combined with the loosely-hung bell-crank levers J J and rock-shaft E, substantially as described, and for the purpose specified. l

3. rlhe knotted Wire H, 'forked levers F, shaft E, wiper P, having hinged plate p, bellcranks J J',-link K, lever L, link n, slide a,

and bar D, combinedl substantially as described, and for the purpose specified.

In testimony that l claim the foregoing as my own I my signature in presence of tWo Witnesses. i
