JAMES LAWRENCE IMOGEE, OF STARR, SOUTH CAROLINA.

PLOWSWEEP.

Application filed September 10, 1923.

To all whom it may concern:

Be it known that I, James LAWRENCE McGicn, a citizen of the United States, residing at Starr, in the county of Anderson and State of South Carolina, have invented certain new and useful Improvements in Plowsweeps, of which the following is a specification.

This invention relates to sweeps for plows, especially plows of the shovel type, and has for its object to provide an improved manner of connecting the sweeps to the plow or standard. A further object of the invention is to improve the construction of the sweep wings with respect to the manner of supporting the same and the operation thereof upon the soil.

Considerable difficulty has in the past been experienced with ordinary sweeps in consequence of the tendency of sweeps to turn or twist on the heel bolt by which the wings are attached to the standard, and when the wings lose the proper set, they are apt to catch in roots and become clogged or gather vines and trash and prevent proper operation. The present invention remedies this defect and also acts to break up the soil in an improved manner.

In the accompanying drawings, Fig. 1 is a perspective view of a shovel plow provided with the improved device. Fig. 2 is a central vertical section of the footof the plow. Fig. 3 is a detail in perspective of one of the wing supports. Fig. 1 is a detail in front elevation of two wings separated and detached.

In the drawings, Fig. 1 shows a plow of the ordinary type having a beam 6 and a loop standard or stem 7 adjustably bolted thereto. The loop at the lower end of this standard receives the heel bolt 8 which fastens the shovel 9 and also the sweeps, to the standard, the shovel being set against the front of the standard, and the sweeps being set against the back thereof, as usual. Each sweep includes a sweep support 10, one of which is shown in Fig. 3, consisting of a cast bar to the front of which the blade 11 is bolted, as indicated at 12, and this bar has a series of upstanding teeth 13, which Serial N0. 661,890.

project above the rear edge of the blade and serve to break up the soil as it passes over or behind said edge. This bar forms a very effective support for the blade and stifi'ens the same.

At its inner end, one bar 10 has an offset plate or part 14 provided with a vertical corrugation or rib 15. The other wing has a similar offset part l f with a rib 15", and each part has a hole 16.

In attaching the sweeps to the standard, the part 1 1 is placed upon or in front of the part 14 and then both are set against the back of the standard, the holes 16 registering for receiving the heel bolt 8. The arms of the standard 7 fit in the grooves or depressions 17 on the car 14, and the rib 15 fits between the arms of the standard. In consequence of this, the wings cannot slip or turn with respect to the standard, but an interlocking engagement is formed which holds the wings rigidly as set. The rib 15, it will be understood, fits within or against the rear side of the rib 15 and in the groove formed thereby, so that the ears are effectively attached to each other and to the standard, and any turning strain is taken by the standard rather than by the bolt, so there is no tendency to loosen the nut on the latter or to strip the threads on the bolt, and the front corners of the blades are held close up against the back of the shovel 9. Sweeps so constructed and connected will have m an y practical advantages over the ordinary type.

I claim:

The combination with a plow standard having a pair of spaced branches, of a pair of sweeps having attaching ears bolted to the standard. the ears having interlocking ribs and grooves engaging with each other and fitting in the space between, the branches of the standard.

In testimony whereof, I affix my signature in presence of two witnesses.
