IMPROVEMENT IN SEEDING-MACHINES.

Specification forming part of Letters Patent No. 23,183, dated March 8, 18.79.

w To all 'whom it may concern:

' being had to the annexed drawings, makinga part of this specication, in which- Figure l is a side sectional view of our invention, taken in the linear rv, Fig. 2. Fig. 2 is an inverted plan ot' the same.

SimilarI letters of reference indicate corresponding parts in the two gures.

This invention relates to an improved means for forming thefurrowswhich receive the seed, as hereinafter fully shown` and described, whereby all rubbishsuch as roots, weeds, and the remains of previous crops-is prevented from interfering with the proper forming of the furrows, and the ground, when planted, left in proper state for the early use ot' the cultivator or other implement used in subsequent cultivation.

To enable those skilled in the art to fully understand and construct our invention, We will proceed to describe it.

A represents a rectangular frame, the back part of which is supported by wheels B B and the i'ront part supported by a pair of wheels, G C, on the axle c ot' which a bar, b, of the trame A rests. To the axle a ot the wheels U U the draft-pole D is attached. To the axle a., at its center, a vertical rod, c, is attached, said rod passing loosely through the bar b.

On the frame A seed-boxes E E are placed.

These seed boxes may be provided with anyV suitable seed-distributing device, and to each seed-box a seed-spout, F, is attached. On the frame A the drivers seat G is placed, and a rope or chain, H, is attached to the front end ot' the bar b and passes through the upper end of the rod c and is secured to the seat G.

In the front part of the frame A there are attached two standards, H H. These standards are secured in the frame by screws d, which may pass through either of a series of holes, e, made in the standards. By this means the standards H' H may be. adjusted higher or lower in the frame A. a

To each standard H' a supplemental seedtube, I, is attached, and these tubes I fit over the lower ends ot' the spouts F, and to each standard H two wings or mold-boards, JJ, are attached in oblique positions, one being at each side of the tubes I, as shown clearlyin Fig. 2. The wings or mold-boards J J are connected at their front ends, and they are attached to the standards H by bolts f, which pass horizontally through the frontendsof the mold-boards and through slots g in the standards H". This mode of connecting the wings or mold-boards to the standards admits ot' a vertical adjustment of the former, as will be clearly understood by referring to Fig. I.

'Io the lower end of each standard H H a V-shaped share or cutter, K, is attached by a pivot, li. To the front end of each share or cutter K a knife, L, is attached by a pivot, t, and to the outer end of each knife a standard, M,is permanentlysecured,`said standard passin g up through guides j attached to the frame A.

The operationis as follows: As the machine is drawn along the seed passes down the spouts F into the tubes I and dropsinto furrows made by the shares or cutters K, and the knives L penetrate the ground and cut all roots, Weeds, sticks, and the remains of previous crops that may be on or in the soil and in the paths of the sharesK. The knives L therefore facilitate the work of the shares and insure their perfect operation. The wings or mold-boards J J grade the surface of the ground at the edges of the furrows, so that the top and bottom of the i'urrows will be parallel and the seed covered at a uniform depth.

It will be seen that the depth of the furrows may be regulated, as desired, by adjusting the standards H higher or lower, and that the knives L may also be adjusted higher or lower to correspond with the position ot' the shares or cutters K, the standards M being secured at any point by adjusting the guides j. Ihe seed, it will be understood, falls from the tubes I directly behind the shares K.

When the machine is to be turned at the ends ot rows the driver on the seat G, by throw face of the ground.

share K, wings or mold-boards J J, with or without the tube I, arranged for joint operation,

ing` himself slightly back and drawing on the rope or chain H, will raise the frontof the frame A, and thereby elevate the shares K, wings or mold-boards J J, and knives L above the sur- DANIEL MARKHAM.
