IMPROVEMENT IN ORN-GROUND MARKERS.

Specicationlforming part of Letters Patent No. 144,146, dated Octcber 2S, 1673; application filed June 28, 1873.

To all whom t may concern: v

Beit known that I, JAMEs H. RYNERsoN, of Clayton, in the county of Hendricks and State of Indiana, have invented a new and valuable Improvement in Corn-Ground Markers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a plan view vof my invention. Fig. 2 is a side view of the same. Fig. 3 is a detail.

My invention relates to markers for cornground 5 and consists, in the following novelties, to wit: First, in a novel guide and4 detachable auxiliary marker attached to the rear oi' the standard; and in the construction and arrangement ot' the marking-plow, auxiliary marker, pivoted standard, and braces, as hereinafter described and claimed.

4A of the drawings represents the horizon tal or main beam ot my marker; B, the crossbeam (l, a caster-wheel, and I) I) the handles. E E represent side braces, connected with the draitbeam by a bolt at a, and to the lower side of the cross-beam` by staples, as shown at c. These side braces, after passing to the rear of the cross-beam, are bent downward, as shown at j', and serve to form the upper section ot' the plow-standard. G represents the lowerseetion of my standard; and it consists ofa single curved and slotted metal ba-r,with perforations through both its j aws to receive thebolt and break-pin next mentioned. hI represents a bolt passingthrough the jaws of the lower section of the standard; and a is a wooden pin,

usually called a break-pin, also passing through `an opening in said jaws. The bolt h serves guide or auxiliary marker next described. This guide and marker H consists in a bent plate of metal flattened and broadened toward its rear end, as shown. It serves not only as a guide to regulate the depth of furrow for the marking-plow, but also to return a portion ot' loose earth from the sides of the furrow, and form a smooth even bed for the seed to be planted. Both the marker proper and the guide H are united together by a single bolt, y, which passes through the slot of the standard, and by which they are made adjustable therein.

This guide or marker H may be detached from the rear end ofthe standard, and the implement used as an ordinary cultivator.

I) represents a brace-rod extending from the cross-bar to the break-.pin in the jaws ot" the standard. This brace is made adjustable upon the beam by means of perforations and holding-pin; and serves not only to hold a-nd brace the pivoted section of the standard, but also to regulate the depth oi' furrow for the marking-plow.

The break-pin is designed to give Way and relieve the plow from danger ot breakage when encountering an insurmountable obstacle.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a coririield marker, the detachable and adjustable guide or auxiliary marker H, substantially as speciiied, and for the purpose mentioned.

2. The markingplow K, and auxiliary marker H, united together by a bolt, in combination with the pivoted and slotted standard G, side braces E, and brace-rods l?, sub-
