SPECIFICATION forming part of Beissued Letters Patent No. 11,504, July 23, 1895. Original No. 509,797, dated Iovember 28, 1893- Application to reissue 10628, 1884; Serial Ira 1 .2 8-

To all whom it may concern.- I Be it known that we, CLARENCE H. DOOLEY and-HARRY L. DO0LEY, citizens of the United- States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in a Combined Check-Row and Drill; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same,'reference being bad to the accompanyingdrawings, and to the letters of reference marked thereon, which form a part of this specifica- The object of'our invention is to obviate certain objectionable defects in check-row corn-planters of the class employing a rotating or oscillating seed-plate. In one construction the rotation of the plate is effected wholly through the tappet-wire, and this is disadvantageous, because the-constant jerking of the wire loosens an'd pull sup the securing stakes, the .wire is'quickly worn and frequently breaks, and further it is not possible to check imposed on the wir'e.- Another objection is inaccuracy in the nuniber of seed discharged at a time, due tothe'lact that a cell m'ade large enough to hold severale s'ay three-kernels oi. corn will frequently get out more or less than this numbers,

Inanother construction ,of machine the seed;plate is rotated continuously by suitable gearing connecting it with the coveringwheels, the seed being discharged from the jbox one at a time by the seed-plate until a given numberhas accumulated in the receptacle, having a valve that is actuated by the tappet-wire. This of course relievesthe latter of work, as itssole duty is to vope'ratethe valve; but this form of planter is-se'riouslyobjectionable, asobviously it cannot be depended on foraccurate work, because, owing to irregularities in the ground, the covering- .wheels will not always make the same number of revolutions between the-tappets, so that at one time more grains will be discharged to the tappet-actuated valve and at another time less.

In our invention we drive the rotating seedaplate by m'eans of the covering or carrying wheeler wheels, and thus freethe wire of this duty; and we use the wire, or rather the v appet thereon,.to control the rotation of said invariable predetermined interval between two tap'pets, and thus insure the discharge from the seed-box of the same number of grains in every instance,

employed. V

Referring to the drawings by letters, Ades-' ignates a portion of the planter-frame; B, one of the covering and carrying wheels mounted on an axle b, and 0 one of the seed .boxes'or hoppers, all-of which may be of any preferred con- .struction. Within thds'eed-box C is the rotating seed-plate D, having a number of cells or openings d, each large enongh to pass but one grain of corn at a timegto suitable delivering mechanism below. Said plate D is provided on the under side with peripheralbevel gearteeth which mesh with a pinion e on a shaft E,

two are alike in construction. Just outside the box the shaft E carries asprocket-wheel f,

that extends acrossthe machine to the other seed-box, which, however, is not shown, as the that is connected by' a chain g with a sprocketwheel h, mounted on ashort shaft H about midway between the seed-box- C and the axle b. Loosely mounted on the outer-endof the I shaft H is a sprocket-wheel 11, connected by 1 a chain j with a wheel J on said axle. It-will thus be seen that provision is made to revolve the seed-plat'efrom the axle b, it being only required to clutch the loose wheel 1 to the shaft 11. Suchclutching'.is effected by the following means: Attached to the wheel 13 and also loose on the-shaft H is a, disk or wheel K, havin .a'rim =k, provided'with internal notches that'are adapted each to be en- .gaged by a roller Z on a dog or arm L,-eecentrically pivoted to andcarri'ed bya plate M, fixed to and rotating with the shaft H. A

coiled spring m, placed between a lug on the plate M and a bearing, on said arm, operates .to normally swing the latter to place the roller 1 into engagement with one of the notches k and thus clutch the wheel K to the shaft H:

.The arm L is prevented from swinging its i roller into engagement with the disk K until it is desired so to do by prolonging it so that its free end can be engaged by a stop-lug n on asliding bar N, which is connectedto the radial arm 0 of a rock-shaft O, that in turn is connected by means of a radial arm 0' and link or bar 0 to the tappet-actuated love:- P of any usual construction. Movement of the lever P will, through the connections just enumerated, slide theba'r N, so as to free-the arm.L from the stop-lug n and thus permit the wheel K and sprocket ito be clutched to the shaft II,- Before the arm L can complete its revolution the tappet will release the lever I, and through the actionof a spring p the slide will resumeits former position with the stop-lug n in the path of and ready to engage the end of arm L to swing it to lift its roller 1 ou'tof engagement with the notched rim of V the cl utch-disk K. From the seed-plate D the grains pass to a valved receptacle whose valves are actuatedfrom the rock-shaft O,

I whence they pass'to the ground by any suitable chute or guide. v i

The motions of our mechanism are so timed menced immediately on the lever being movedby a tappet and finished some time before the next tappet is reached,so that-the corn is inthe valved receptacle. ready for delivervwhen the said next tappet strikes the lever. It will be seen that the degree of movement of the said platedepends entirely on the clutch-arm L, and as this has an invariable amonnt 'of motion (as shown, a single revolntion) it is insured that the same number of grains'will always be d ischargedby said plate. 7

The timing is such that the predetermined movementof the arnnL will always occur in,

the interval of'travel from one tappetto' another. Of con r'se the timin g of the gearing determines the degree of; movement of the seedplate at each operation, and accordingly the thenumber ofseed discharged to the valved receptacle.

We wish it understood that we do not limit ourselves to the details of construction shown,

'but regard ourselves as entitled to such va riations therefrom as fall within the scope of V our invention. v p
