application filed March 18, 15 22.

To all whom it may concern:

Be it known that 3:, JOHN A. DAUGHTERY, a citizen of the United States, and a resident of Goldsboro, in the county of Wayne and State of North Carolina, have invented certain new and useful Improvements in Plow Structures, of which the following is a specification.

This invention relates to plow structure, and more particularly to improvements in the construction of the standard of cultivator plow or the like and the connection of the beam therewith.

The object of the invention is to provide a standard which is e: :ceedingly strong and consisting in one compact casting or unit particularly adapted to be connected in a highly efiicient and durable manner to the associated plow beam.

It is also an important object of my invention that novel means he provided for securin the beam to the standard which will distribute the strain imposed upon the beam in such a manner that every possibility of breaking the connection between the beam and standard is eliminated.

Other objects relating to details of construction will hereinafter appear.

The invention is illustrated by way of example in the accompanying drawing, in which:

Figure 1 is a view in side elevation of a plow in which the present invention is incorporated, the beam and handles of the plow being partly broken away,

Figure 2 is a detail vertical sectional view taken substantially on the line 2-2 of Figure 1, and

Figure 3 is a transverse sectional view taken on the line 33 of Figure 1.

Referring to the drawings more particularly, S indicates generally the plow standard of the present construction, M a pair of mold boards, P the plow point, and B the beam.

More specifically the standard S consists in an upper body portion 10 which is formed at its lower end or side with a downwardly projecting and curved portion 11 which terminates in the runner 12, said runner having the usual shoe 13 detachably connected thereto. Also-this runner carries a pair of wings or scrapers 14: which are secured thereto in any desirable manner, as by the Serial No. 544,795.

bolts 15. The body portion 10 of the standard has also the forward downwardly extending portion 16 which carries the mold boards M and point P. Similarly the standard S may be formed with a pair of sockets 19 which may receive plow handles20.

The beam B is of the usual construction; that is, with its rear portion 20 curved downwardly as shown and the body portion 10 of the standard is provided with a socket 21 which extends entirely therethrough and which is adapted to receive the rear portion of the beam B. The socket v is slightly curved in order that the rear end portion of the beam B may fit therein. The socket occurs centrally of the body portion 10 ofthe standard and substantially vertical. The body portion 10 is also formed with a pair of upper bosses 22 and a pair of lower bosses 23 and intermediate these bosses there may occur a recess 24, said recess being merely to increase the lightness of the standard. Through each pair of bosses there extends a bolt 25, each bol having a squared head 26 which is tightly fitted in a recess 27 provided in the associated boss. Al o each bolt has suitably threaded thereon a nut 28 which when ightened for securing the beam B is brought against the outer face of the associated boss. It will be observed that the head 26 of each bolt 25 when in securing position abuts the associated face or side of the beam B as illustrated best in Figure 2. By this arrangement the stress or pull imposed upon the beam B is distributed between the shanks of the bolts 25 and the bolt heads 26. This eliminates any wear of the bolts 25 and also produces an exceedingly efficient connection between the standard S and beam B.

It is believed from the foregoing that the many advantages arising from the pres-.

ent invention will be fully understood without further elaboration.

In relation to the particular connection between the standard S and beam B it might be said that the same connection may be utilized for connecting similar structural elements and with like advantages. It is believed that the substance of this statement is clearly apparent.

I claim: ing bolts extending through said upper and A plow frame comprising a substantially loWer bosses and said socket and having 10 inverted U-shaped casting having a bight squared heads, one boss of each pair of portion formed With a Vertical beam rebosses being formed with squared openings eeiving socket extending entirely theresnugly receiving the squared heads of said through, said bight portion being formed bolts. at opposite sides of said socket with pairs of upper and lower bosses, and beam fasten- JOHN A. DAUGHTERY.
