THEOBALD BRAUN, OF ATI-IY, ASSIGNOR OF ONE-HALF TO ADAM FEIK, OF VOLOANO, WEST VIRGINIA.

SEEDING SPECIFICATION forming part of Letters Patent No. 351,247, dated October 19, 1886.

Application filed March 29, 1886.

To all whom, it may concern;

Be it known that I, THEOBALD BRAUN, a citizen of the United States, and a resident of Athy, in the county of Vood and State of \Vest Virginia, have invented certain new and useful Improvements in SeedingMachines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side view of myimproved seeding-machine. Fig. 1* is a transverse section through the seed-box and the beam taken on line 00 ac, Fig. 1, the sprocket-wheel and outer washer being shown in section. Fig. 2 is a similar view of the same seen from the other side. Fig. 3 is a front view of the machine. Fig. 4 is a longitudinal vertical sectional View of the machine; and Fig. 5 is a perspective detail view of the shaft of the seeddisk and its sprocket-wheel and disk, showing portions broken away.

Similar letters of reference indicate corresponding parts in all the figures.

My invent-ion has relation to that class of seeding-machines in which a seed-box is secured upon a beam having handles and opening and covering plows similar to a cultivator-beam, and in which a wheel is journaled between arms projecting from the forward end of the beam, and has suitable gearing which connects it to the seed disk or wheel in the seed-box, imparting motion to the said disk;

. and it consists in the improved construction and combination of parts of such a machine, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the beam,which is provided at its rear end with the handles 13 B, and which is formed with the standard 0, to the lower end of which the openingshovel D is secured, and to the rear side of which the seed-tube is secured, as shown at E, and the forward end of the beam which is provided with a suitable clevis or hook for the attachment of the team is formed with two downwardly projecting Serial No. 196,983. X0 model.)

braced arms, F F, having bearings G at their lower ends. The shaft H of the drive-wheel I has its ends journaled in these bearings,and a sprocket-wheel, J, is secured upon the shaft at the side of the drive-wheel, revolving with the same. The rear portion of the beam is provided with a longitudinal slot, K, to the rear of the standard, and bearings L L are formed in the sides of this slot, having removable upper portions, and a shaft, M, is journaled in these bearings and has the seed-disk N secured removably upon it between the bearings. A ratchet wheel, O, having its teeth facing forward, is secured upon one end of this shaft, and is engaged by a pawl, P, which is pivoted forward of the shaft, and may be tilted out of engagement with the ratchet-wheel. The other end of the shaft outside the other bearing is provided with a disk or washer, Q,

R, having a sprocket-chain, S, passing over it and the wheel upon the drive-shaft, revolves upon the seed-shaft outside of the washer. Another washer, T, revolves upon the shaft outside of the sproeketwheel, and this washer and the sprocket-wheel are formed with a notch or groove, U and V, in their bores,which WV, in the end of the shaft. A key, X, is socured by means of a chain, Y, to the outer washer, which is retained upon the shaft by means of a pin or key, Z, and may be inserted into the grooves, when they have all been brought to register, when the shaft will revolve with the sprocket-wheel, while, when the key 'is removed, the sprocket-wheel may revolve upon the seed-shaft.

The forward part ofthe portion of the seeddisk,which projects below the 'slot in the beam, is covered and surrounded by the enlarged upper end, A, of the seed-tube, preventing any grain from being lost.

The seed-box B is secured upon the upper side of the beam over the slot in the same, having hasps O at its ends, which hasps fit over staples D upon the top of the beam, and are retained by means of hooked pins E, inserted through the staples, and the forward end of the seed-box is provided with a partiturning upon the shaft, and a sprocket-wheel,

notches or grooves may register with a groove,

tion, F, which is immediately above the highest point of the seed-disk, and which is provided at its lower end with a flexible brush, G, for the purpose of smoothing the grain con tained in the seed cup or cups H in the periphery of the seed-disk.

The sides of the seed-box are scooped out toward the periphery of the seed-disk, as shown at I, for the purpose of carrying the seed toward the seed-disk, and a block, J, bears with its forward end against the rear portion of the periphery of the seed-disk, being secured in the bottom of the seed-box, and prevents any seed from dropping out at the rear end of the box, while the seed-disk carries the seed in its cup or cups forward through the empty forward half of the seed-box down into the wide upper end of the seed-tube.

It will be seen that when the machine is in operation the pawl is thrown out of engage-e and the pawl is engaged with the ratchet-- wheel, preventing the sprocket-wheel from carrying the shaft and disk with it in its revolutions.

The washer upon the outer end of the seedshaft serves to give the key a better hold in the groove of the sprocket-wheel, and to brace 'the said key, confining a greater portion of the key than if the washer were removed.

A marker-arm, K, has its inner end, L, bent downward, and rigidly secured in a rectangular block, X, which fits removably in an obliquely-cut rectangular hole in the forward end of the beam, and a rod, M, is suspended from the outer end of the arm and braced by means of a rod, N, pivotally secured to the middle of the arm and of the rod. This rod depends from the outer end of the arm and will mark in the soil a line, which indicates the next row to be planted, and the arm may be turned to mark on either side of the seeder by reversing said block X.

Two arms, 0'' O, are secured at their forward ends to the openingstandard,andhave the covering-shovels P Psecured upon their downwardly-curved rear ends, and are connected by a cross-piece, Q, and these shovels will cover the seed and form aridge over it, which will have two low ditches or grooves at its sides, which will absorb the water and prevent the grain from being rotted by too much water.

The seed-disk haspreferably only one cup in its periphery when it'is used for planting corn or other seed which is planted in hills,

but when it is desired to either plant in hills at a less distance between each other or to use the machine as a drill a disk is used with a number of cups in the periphery, and the said disk may be placed upon the seed-shaft by removing the seedbox, raising the upper halves of the bearings for the shaft, and removing either the ratch et-wheel or the washer, sprocket-wheel, and outer washer, when the disk upon the shaft may be removed and the other disk placed upon the shaft.

Having thusdescribed my invention, I claim and desire to secure by Letters Patent of the United States 1. In a seeding-machine, the combination of a grooved shaft carrying the seeddisk, the washer Q, the sprocket-wheel R, the washer T, the removable key X, the pin Z, the ratchet-wheel O, and the pawl P, substantially as and for the purpose set forth.

2. In a seeding-machine,'the combination of the beam A, provided with an obliquely-cut hole in the forward end, the rectangular block X, the rod K, rigidly secured in said block, the rod M, and the brace N, substantially as and for the purpose set forth.

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

ADAM FEIK, R. ALEXANDER.
