CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 282,012, dated July 24:, 1883. Application filed April 12, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that we, ANDREW RUNs'rETLER and J AMES A. MARLAY, both citizens of the United States, and residents of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Check-Row Attachments for Corn-Planters, of which the following is aspecification.

Our invention relates to a check-row attachment for corn-planters. r

The object of our invention is to provide an in termittently-rotating shaft placed transversely across a corn-planter, upon each end of which is journaled a forked lever carrying an automatic driving-pawl engaging with a ratchet keyed on said shaft and combined with a stoppawl attached to the check-rower frame engaging with another ratchet-wheel, also keyed on said shaft, which stop-pawl is lifted for rotating the shaft by a lifting device rigidly af fixed to the forked arm. This mode of journaling the forked arm directly on the intermittently-rotating shaft which operates the seeding device is very important, as the driving-pawl attached to the forked arm at one end of the machine acts as a stop against a backward movement of the shaft, while the driving-pawl attached to the other lever is moving backward over the ratchet-teeth. This is a positive and easy-working device.

In the accompanying drawings, Figure 1 is a plan 'view of the runner-frame of a doublerow corn-planter having our check-rower attachments applied thereto. Fig. 2 is an end view of our check-rower attachment secured in position on one of the seed-boxes. Fig. 3

V is a broken plan of a modified form of the seed-dropper bar.

forked-lever attachments. Fig. 4 is an inside elevation of the lower end of the forked lever, shown in Fig. 3, and the ratchets and pawl connected to the transverse driving shaft. Fig. 5 is a plan view of the adjustable shakerlever, showing its driving connection with the Fig. 6 is an elevation of the shaker-lever.

A A represent the frame-bars of the runnerframe of an ordinary two-wheeled corn-planter; B B the seed-boxes; O, the reciprocating dropper-ba r.

D represents the shaker-lever. It is preferably made in two parts, (1 (1, attached by a flange, a, and bolts 1) to section 0, which is at tached at d, by suitable journal-boxes, to the cross-bars A A of the riulner-frame. Sections (1 d of the shaker-lever are attached to section a by means of bolts passing through slots 1) made in the flange a of the sect-ion, so as to allow the shaker-lever to be adjusted to the plane of the pitman e, laterally as well as vertically.

F represents the frame of the check-rower attachment, which is attached to the seed-boxes by means of brackets G.

H represents a transverse rotating shaft journaled upon the frames F F.

I representsa beveled gear keyed upon said shaft and meshing with bevel-gear I,'n1ounted upon the runner-frame.

K represents a crank-pin, upon which the pitman c j ournals at one end, the other notched end of the pitman resting upon the pin k of the shaker-lever for reciprocating the seedbar 0, with which said shakerbar is connected in the ordinary manner.

Duplicate forked levers and intermittentlyoperating driving devices are used upon each end of the shaft H, so'as to be operated by a knotted cord, wire, or chain, which is stretched in right lines across the field, and engaging with either one of said forked levers without passing transversely across the machine.

L represents the forked levers loosely'journaled upon the shaft H. it represents a nut and collar for holding said forked levers in position laterally against the ratchets m 01,

which are rigidly mounted on shaft H. These lever L moves backward finger O lifts to lever L, so as to raise pawlP out of contact with teeth a to allow of the rotation of shaft H, driven by pawl N.

0 represents a finger which may be used to strike upon pawl P and force it into contact with one of the teeth, a, and thereby arrest the rotation of shaft H.

Figs. 2, 3, and rcpresent a modified form of constructing the liftingarln O and finger O. This modification consists in providing segmental loop or guide arms 1' r, which are c011- nected to lifting-arm 0. It is obvious that pawl P, being a gravitatingpawl, will auto matically engage with the teeth or andbelifted out of contact therewith by means of the lifting-arm O, and that parts 0 and arms 1- r could be omitted.

Q, representsa retractile spring attached to arm or lug p'of lever L, and connected at the forward end to a lug on the frame F, the recoil. of which retracts the lever L to its normal position (shown in Fig. 2) as soon as the knot is passed out of engagement with fork f of the lever L.

R represents a guide-pulley for directing the cord into the fork f; and t trcpresent frictionpulleys mounted upon a bracket attached to arm T for sustaining the weight of the cord and chain.

The operation is as follows: Forked lever L occupies its normal position, as shown in Figs.

1, 2, andxl. \Vhen a knot upon the cord or" chain engages with the fork f, lever L is can ried backward and shaft H isrotated by means of the driving-pawl N and rack-teeth m. This movement carries lifting-finger O away from supporting stop-pawl P, which. drops upon rack or and engages one of the teeth and arrests the motion of shaft H. Spring Qinstantly retracts the lever L, which moves freely forward upon the shaft H, pawl N sliding over one of the teeth, m, engaging with the next in rear for a second motion of the dropper devices. During the operation of one of the levers L the lever on the other end of said shaft is in its normal position, with its pawl N in engagement with one of the ratchet-teeth, m, and acts as a stop to prevent a backward movement of the shaft while the opposite forked lever is be ing retracted for a second engagement. As the stoppawl P from contact with one ofthe teeth, 11, allow-ing shaft H to berotated by driving-pawl N. Each partial revolution of the shaft H moves gears I l" a sufficient distance to make I a half-revolution of crank-pin K, and makes a complete single throw of the dropper-bar O, and hence dropping one charge of seed for the hills.

Ve do not broadly claim an intermittentlyrotating shaft for operating the seed-dropping devices of a check-rower, said shaft having at each end a disk provided with ratchet-wheels, the teeth of which sit in opposite directions, a forked lever being pivoted to the disk and having a rigid end for engaging one ratchet-wheel to rotate the shaft and operate the seed devices, and a pivoted pawl acting on the other ratchetwheel to prevent backward rotation of the shaft, said pawl being disengaged from its ratchet by a cam projection on the forked lever to permit the latter to rotate the shaft on its return movement.

Ve claim 1. The combination, with the rotating shaft H, of the levers L, journaled on opposite ends thereof, and each carrying an automatic driving-pawl, N, engaging with rack-teeth m, one of which levers and its driving-pawl remains in normal position for driving while acting as a back stop while the opposite lever is operated by the knotted cord, substantially as described.

2. The combination, with the intermittently rotating shaft H, of the forked lever L, journalcd directly on said shaft and carrying an automatic driving-pawl, N, and a lifting-finger, O, for operating the stop-pawl P, substantially as described.

The combination, with theintermittentl yoscillating shalt H, of the oscillating levers L, journaled directly upon said shaft, and each carrying an automatically-operating driving pawl, N, one of which pawls is at all times ready for driving, and each armed with. a rigidly-attached lifting-finger, O, for releasing a stop-paw], P, substantially as described.

4. In a corn-planter check-rower having an intermittently-rotating shaft, H, and ratchets m and a rotating therewith, the oscillating lever L, journaled on shaft H, having the finger O, and slotted guide 7' rfor operating the pawl P, substantially as herein set forth.

In testimony whereof we have hereunto set our hands.
