Specification forming part ofrLetters Patent No. 4l2,6l21., dated May 3, M64.

To all whom, t may concern:

Be it known that I, JOHN WATERMAN, of Keokuk, in the county of Lee and State of Iowa, have invented a new and Improved Seeder and Planter Combined, and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this speciiicatiomin which- Figure lis a plan of my improved machine, a portion of the hopper being broken away to expose the relative positions of the coverers Fig. 2 is a rear elevation of the same, partly in section.

Similar letters of reference indicate corre sponding parts in the several figures.

This invention consists in a novel machine of simple and cheap construction, which, besides being superior in its operation as a seeder or corn-planter, is adapted to be converted with facility into an adjustable harrow, as will be hereinafter explained.

In order that others skilled in the art to which my invention appertains may be enabled to fully understand and use the same, I will proceed to describe its construction and operation.

YIn the accompanying drawings, A A represent the outer beams of a converging frame, which are hinged or pivoted at front to the parallel central beams, B B. The beams B B are securely connected together by a rod, C, passing through lugs c c.

D DV represent smaller diagonal beams, which are also hinged or pivoted to the central beams, B. The object in thus attaching the beams D and also the beams A is to allow the adjustment of the teeth or plows when the machine is converted into a harrow, as will be explained.

E represents a hopper mounted upon metallic supports E E, which are fastened to and near the rear ends of the beams A A.

F represents the slide, which may be reci procated by the hand-lever G when the machine is being used as a corn-planter, or by other suitable mechanism when smaller grain is to be sown.

The operation of the slide F is designed to be facilitated by the employment of a spiral spring, H, which acts to restore the closed condition of the hopper when the lever G has been thrown in the proper direction to open the apertures in the hopper.

I I represent adjustable and removable boxes, into which the corn to be planted is placed.

Ihe hopper, in the present illustration of my invention, is provided with four apertures for the passage of grain. Over each aperture in the hopper one of the boxes I may be placed, so as to plant four hills at every movement of the lever G, or one or more may be slid from over the aperture or apertures, and the remainder ot' them adjusted over the ports through which it is desired to have the grain pass.

J J may represent the conducting-tubes applied to the hopper in the usual manner. These tubes are arranged to work directly in the rear of the drill-teeth, indicated by the letter K.

K K2 represent coverers secured in the rear ends of bent arms or supports k la. The deflected portions of the arms k are screw-threaded and fit in corresponding apertures in the beams D D, and the position of the coverers K with relation to the conductingtubes may be varied, as circumstances may require, by means of adjustable nuts cl k2 on the threaded portions of the arms k, which nuts are applied and adapted to work one on each side ofthe respective beams D D. The arms 7c of the coverers k2 are adj usted in the desired position by nuts k3 k3, and the deflected threaded portions of said arms 7c may also serve to connect to the beams A metallic frames L L, in each of which may work a roller, L.

M M may represent wheels, whereby may be performed the double function of supporting the machine and limiting the depth to which the drill-teeth K and coverers K Kz penetrate. The shanks m of the wheels M are secured and turn loosely within a hollow threaded standard, M', which rises from a disk, M2, and which works within a corresponding aperture in the bar N.

N represents a circular nut, by means of which the screw M can be rigidly retained in any position in which it may be placed, and the said nut N is adapted to be more readily manipulated by a small handle, u. The respective ends ofthe bars N are screwed tothe beams A and D.

To each end of the beams B is fastened a metallic plate or bar, O, which projects in an outward direction, and is overlapped by a similar plate7 O', projecting from the beams A. These plates may each be held immovl ably together by a thumb screw, o7 which works in a bracket-shaped standard, 0.

P represents a wheel, which may be pivoted between the beams B B. This wheel serves to support the front of the machine and expedites the turning thereof.

Operation: The remarks accompanying the above description of the construction of the machine will serve to explain the manner in which it operates when used as a seeder or corn-planter.

To convert the machine into an efficient harrow, it will only be required to remove the hopper E, bars N, and rollers L', together with the respective appurtenances of each. As these members are connected to the main body of the machine by the ordinary screws and nuts7 little difiiculty will -be met with in disconnecting them. After this has been accomplished, the several beams may have an additional number of cultivator-teeth inserted and secured in apertures with which they may be providecl',\vhen the machine will constitute a har-row admirably adapted to perform the work of this implement. The hinged beams A D may be readily contracted into a smaller compass when the machine is converted into a harrow by unscrewing the thumb-screw 0. By these screws, as employed in connection with the plates O, the beams may be firmly adjusted in any position which they may occupy. The rod() and lugs c cform a horizontal hinge, whereby either side of the harrow may be elevated with facility to avoid obstacles.

This machine is simple, may be constructed at little cost, and will constitute a most serviceable implement forV the farmer.

Having thus described my invention, the

following is what I claim as new thereinand desire to secure by Letters Patent:

2. In combination with a seeder constructed as described, thelaterally-adjustable coverers K K k k', constructed and operated substantially as specified.

The above speciiication of my improvement in corn-planters signed this 6th day of October, 1863.
