ELI FAIRLEY MURRAY, OF LAUREL HILL, NORTH CAROLINA.

PLOW.

SPECIFICATION forming part of Letters Patent No. 637,939, dated November 28, 1899.

Application filed May 8, 1899. Serial No. 715,959. (No model.)

To all whom it may concern:

Be it known that I, ELI FAIRLEY MURRAY, a citizen of the United States, residing at Laurel Hill, in the county of Richmond and State of North Carolina, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to plows, and more particularly to improvements in marking attachments for plows of that class in which a lateral rod having a depending guide fixed to its free end is pivoted to the plowbeam and which can be thrown over to either side of the beam, so that the depending guide will trail on either side of the path of the plow.

The object of the invention is to provide a simple, inexpensive, and efficient device of this character.

With this object in view the invention co11- sists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the drawings, Figure l is a perspective view of my improved marking device as attached to an ordinary plow. Fig. 2 is a transverse section. Fig. 3 is a detail perspective view of the outer end of the hinged rod, showing the manner of attaching it to the depending guide-rod.

In the drawings, 1 denotes the shoe or strap which straddles the beam and is removably secured thereto by means of the lateral thumbserews 2 2.

3 represents a standard rigidly fixed to the shoe 1 and having a flattened upper end 4.

7 and 8 denote lateral diagonal braces rising from the standard 3 and provided at their outer ends with forked sockets 7 8.

1O denotes a horizontal cross-brace' fixed to the standard 3 and to the diagonal braces 7 and S.

5 denotes a rod consisting of two parts a b, the part b of which has a forked end, the members of the fork being flattened out and straddling the flattened end of the standard 3 and secured thereto by a pivot 3. One part of the rod 5 is telescopic within the other part to vary the length of said rod. In the present instance I have shown the part b of the rod as tubular and preferably formed of metal and the part a solid and preferably of wood. The part a is inserted into the tubular part b and is secured therein at any desired adj ustment by the set-screw c. The part b is of a length to extend beyond the V-shaped sockets 7'8 and is adapted to rest and be supported in a horizontal position in either of these sockets. To the outer end of the part a is secured a sleeve (1, having a shank d and a head (1 9 denotes a short stick which is secured in the lower tubular end e of the hinged clamp f by a set-screw g. The member f of the clamp f is secured to the tubular portion 6 by a set-screw f In securing the clamp to the shank d sufficient play is allowed to permit of the stick 9 yielding should it strike any obstructions, and thereby prevent the breakage of the stick.

The manner of using my improved furrowgage is as follows: The plowman first carefully runs a guide-row, and by guiding the plow for the second row so that the end of the stick is vertically above the guide-row or trails in the guide-row the second row will be exactly parallel with the first, and by using the second row as a guidethe third row will of course be parallel to the second and first rows, and so on. Then desired to lay the rows closer together or farther apart, the part or member a of the hinged rod is adjusted accordingly and held at such adjustment by the set-screw c.

It will of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured byLet ters Patent, is-

1. The combination with the plow-beam, of the shoe detachably secured thereto, the vertical standard fixed to said shoe and terminatingin a flattened head, the diagonal braces extending laterally from the standard and having their free ends formed with forked sockets, and the rod having abifurcated end the members of which are flattened and straddle the aforesaid head and are secured thereto by a pivot-bolt, said rod adapted to be supported in a horizontal position in either of the forked sockets, substantially as and for the purpose set forth.

2. The combination with the beam,of a shoe, a standard fixed to the shoe, the diagonal braces formed with forked sockets, a rod hinged to said standard and adapted to engage either of said sockets, a headsecured to the free end of said rod, a hinged clamp loosely secured to said head and provided with a tubular portion, and a stick removably secured to said tubular portion of the clamp, substantially as and for the purpose set forth.

3. The combination with the beam, of the shoe, the standard fixed to the shoe and formed with forked sockets, a rod hinged to ELI FAIRLEY MURRAY.
