WILLIAM DYZERT, OF GETTYSBURG, PENNSYLVANIA.

||v| PRovEMENT iN C'ULTIVAToRs.

Specification forming part of Letters Patent No. 3,709, dated August 16, 1844.

To all whom it may concern Beit known that I, VVILLlAM DYZER'I. of Gettysburg, in the county of Adams and State of Pennsylvania, have invented a new and use'- ful improvement in seeding and cultivating corn, 85e., which I denominate the Universal Gultivatorg and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompa nying drawings, which form a part of this specioation, in which- Figure l represents a one-horse threeshovel lt is constructed as follows:

A square frame is made, consisting of three longitudinal pieces, a, each having a tenon at one end that enter the mortises in a crosspiece, b, which tenons are placed at equa-l distances apart. The two outside pieces have mortiscs through their sides, near thefront end, opposite the tenon above named, into which a front cross-piece, c, is tenoned, said cross-piece having a mortise at its center for receiving a tenon on the center longitudinal pieceI a. This forms a stout compact frame, and from its under side are three posts or standards,projectipgin an inclination forward, one from each longitudinal beam a. To these the shovels e are attached, the two outer ones slanting, so as to turn the furrows outward, and the center one straight. Staples are driven into the outer sides ofthe beam a at ff, into which shafts are put, and on the tops of the outer beams are similar staples for receiving the handles of the cultivator.

When ground is to be forked 1 attach forks to the standards d in place of the shovels, as shown in Fig. 2. In this machine two frames like the one described are placed side by side at a sufficient distance apart, and are connected by two or three braces of iron, g, to which a stiff tongue, h, is attached. To this machine two horses are hitched, by which it is drawn through the ground, steadily and eftectually performing the work for which it is intended. For the last plowing of corn shovels, as rst described, may be substituted for the forks.

These will finish one row in the center and halt' finish two rows on each side. All these changes are made with two ofthe single-horse frames first described.

Fig. 3 represents a double two-horse plow with four shovels-that is, with the two outside shovels left ott'. This is effected simply hy having two additional cross-pieces to substitute for those marked b and c, which are designated b and c. In Fig. 3 they are made like the other cross pieces, but only have mortises for two beams a. This portion of the machine completes one row of corn at a time, and is used with two horses where the ground is somewhat stiff, instead of that last before named. The iron braces g, which connect the two sides ofthe frames of the two last-named machines, are curved upward high enough to clear the top of the corn and carry the tongue abo ve it, the traces being hitched to a whifiletree, t', attached to each frame. The handles ot' the two-horse machine are carried to one side, as shown in the drawings, for the purpose ot' allowing the man who holds itto walk on one side the row.

With this universal eultivator the whole operation of working the corn in any ground can be accomplished'.

In planting I employ a gage. consisting of a frame of four pieces, from which two standards project downward, armed with iron, to gage for dropping the corn a certain distance apart, equal to what is required bythe cultivator, the two being adjusted to each other, oi' common construction.

What I claim as my invention, and desire to secure by Letters Patent, is

The curved iron braces whichconnect the two sides together, in combination with said sides and the tongue, constructed for the purpose and arranged in the manner above specitied.
