Letters Patent No. 113,422, dated April 4, 1871.

IMPROVEMENT IN CORN-PLANTERS.

The Schedule referred to in these Letters Patent'and making part of the same.

To all whom it may concern Be it known that I, LEWIS GRAHAM, of Plymouth,

in the county of Hancock and in the State of Illinois,

have invented certain new and useful Improvements in Corn-Planters and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the acccompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a corn-planter, as will be hereinafter more fully set forth.

In order to enable others skilled in the art towhich my invention' appertains to make and'use the same, I will now proce-ed to describe its construction and operation, referring to the annexed drawing, in which-f Figui-e1 is a plan view, and

Figure 2, a side elevation of my machine.

` Figure 3 isa bottom view showing the mode of 0perating the feed-slide.

Figure 4 is a side view of a portion of this mechanism.

A represents the frame of my machine, through which, at a suitable point, passes the ale B.

On this axle are placed two wheels, C C, in the outercircumference oi' which are inserted cross-pieces a, a, extending on botll sides of the wheel, and placed a regular distance apart, forming markers to show the hills.

On the inner side of each wheel C are placed cams b b, which operate, in succession, a lever, d, hinged t on the frame A, as shown in g. 4.

This lever bears'against another lever, D, the rear end of which is pivoted on the under side of the frame, while the front end is pivoted to the feed-slide E, said slide passing through the hoppers G G and feed the corn in the usual manner to the conductors II and shoes I, into theA ground. Under the rear portion of' the frame A are placed two caster-wheels, J J, to turn the lmachine on.

The tongue K is pivoted or hinged in the rear end of the frame, and passes through a slotted standard, L; in fi'ont, ,to prevent any zigzag motion, and also to regulate the depth by means'of a pin through said standard.

M is a foot-lever pivoted on the side of the tongue, and connected by a chain, c, with the front end ofthe frame.

With my machine it requires no marking olf and saves the expense of one -hand while planting.

, lo operate the machine we will suppose the tongue is brought up to thetop of the standard L; then, by moving, it will opera-te. the feed-bar.

In turning, press the foot-lever holding the end of the tongue up that raises thel machine oti'of the main wheels G C and throws the weight on the casters J J.

After turning bring the runners orI shoes I I in proper' position, and turn the wheels G G so that it is just ready to drop; relax the weight, and it is ready to go ahead.

1f, by reason of rough ground 0r accident, it should get out of line, raise-,the planter as in turning and tu19n the wheels backward or forward, as the case may require, and let down again. Y

Having thus fully described my invention,

Whatl claim as new, and desire to secure by Letters Patent, is V 1. -flhe combination of the hinged lever el and pivoted lever D and cams b b on thclwheels C C, to operate the feed-slide, substantially as herein set forth.

2, The arrangement of the frame A with wheels C C, having cams b I1 and markers a a, wheels J J, levers (Z and D,.feedslide E, hoppers G G, conductors H, shoes Land the hinged tongue K, all constructed to operate as and for the purposes set forth.

In testimony thatI claim the forcgoin g I have here- -iInto set my hand and seal this 4th day of February,

LEWIS GRAHAM. [n s.]
