IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 22,859, dated February 8, 1859'.

To all whom t't may concern..-

Be it known that I, JAMES Donnas, of Little Rock, in the county of Kendall and State of Illinois, have invented a new and useful Machine for Cultivating Corn, called The Dundas Gorn-Cultivator,77 of which the following is a full and exact description.

The nature of my invention consists in arranging a number of plow-shaped shovels to a proper frame, suspended to a single axle, which is sustained by apair'ofcommon wagonwheels, having a tongue attached for the purpose of harnessing thereto a pair of horses or other animals used for similar purposes; also, by a peculiar arrangement ofthe shovels, the earth is thrown from the young cornplants, and the same shovels are readily arranged to throw the earth toward the plant as may be required; also, by detaehing a siugle catch the plows or shovels rise above the surface of the ground, so that the machine may be driven about the field or on the road from place to placeas may be desired.

To enable others skilled in the art tomake and use my invention, I will proceed to describe its construction and operation, reference being had the accompanying drawings, where- Figure l represents a perspective view of the machine; Fig. 2, a longitudinal section of the same. No. 1 represents the movable shovels arranged to throw the earth toward the plants 5 No. 2,the same arranged to throw the earth from the plants. No. 8 represents a front view ot" the stationary side shovels.

Let a areprescnt two ordinary wagon-wheels; b, an axle resting in the hubs of the wheels a a.

c c are two pieces of timber passing through the axle. The forward end of the pieces c o are connected by the bar d by means of the bolts ee. The beams o c pass outward back ofthe axle b, forming supports for the platformf. I then .place a seat for the driver on the platform fand secureit to the same. The seat is represented at g. I then pass two inclined bars through mortises cut inthe beams c c. These bars are shown at 7L h, being connected at the upper end by the cross-bar i, which has a slant for one of the bars Vh, as shown in Fig. 1, the bar h being secured'at of the tongue m.

any point in the slant by inserting the pin j. The hars h h are supported on the iron rod 7c r, passing through the timbers oo, also through V the hounds l Z and the tongue m.

n n represent two connecting bars or braces attached to the head of the bolts e and by means of eyebolts to the lower end of the bars h h. I also bolt to the side of the beam o c two other inclined bars, as shown ato o, and brace them by means ofiron rods, as shown at l). Y

gj represents a crossbar resting on the upper side of beam o c and working on a pivot at r. The opposite end is made to slide under the iron staple s. I then insert a spring between. the bar q and axle b, as shown at t. This spring presses the bar q against the end I then attach a short piece of chain, as shown at l l, one end of which is fixed to the eross-bar d and the other end Ato the tongue m.

o o represent the. ordinary cultivator-shovels attached to the bars o o.

zo 1o represent two half-shovels attached to the lower ends of the bars h h.

The operation ofthis machine is as follows: First, the tongue m is movable on the rod la 7c. Consequently the bar d rests upon the upper side ot' the tongue. Then, the bar q being pressed against the end ot' the tongue, the beams o c are retained in the same plane with the tongue. .In this position the machine is in readiness to cultivate the corn. When it is desired to withdraw the shovelsand elevate them above the surface of the ground the driver places one of his feet against the bar Vq, and, drawin git slightly backward, releases the end ot'- the tongue, and the weight of the driver causes the platform lto descend, tilting the front part of the frame upward in the position as shown at Fig. 2. The chain u prevents'the machine from too great an elevation, and the bar q, being released, `is pressed forward under the end ofthe tongue m, which iixes the machine in the position as shown at Fig. 2. An oscillating or side motion can be given to the shovels fw w by the driver pressing the bar i either right or left, the-mon tises in the beams e c being enlarged at the sides to allow the bars h h to play sildewise, as shown by the dotted lines on No.1, bringingthe points ofthe shovels at x x alternately. By The arrangement of the haltshovels w w this operation,ittl1e plants are notinastraight in connection With the bar h h and t', to be line,the driver can avoid them by moving the moved to the right or left at the pleasure of shovels to the right or left. the operator.

Observe that the half-shovels can be taken l out and reversed for the purposes before men- JAMES DUNDAS' tioned in the specification. Witnesses:

What I claim as my invention, and desire JOHN M. VANESDEL, A to secure by Lrtters Patent, is J. MCCLURG.
