CARPEN- cn, a citizen of the United States, residing Morrillton, in the county of Conway, fate of Arkansas, have invented certain w and useful Improvements in Plowweeps; and I do hereby declare the followg to be a full, clear, and exact description the invention, such as will enable others 'illed in the art to which it appertains to ake and use the same.

This invention relates to plow-sweeps, and as for its object to provide a sweep consting of two wings which are so connected iat they may be spread apart or closed tother to make a broad or a narrow sweep, ins adapting the same for different kinds work.

In the accompanying drawings, Figure l a front view of the sweep. Fig. 2 is a ack view. Fig. 3 is a front view showing 1e parts in another position. Fig. 4 is a =ction on the line 4-4 of Fig. 1.

As shown in the drawing, the sweep consts of a point 5 and wings 6 and 7 respecvely, which are substantially triangular in iape and overlap, and are pivotally conected at one of their cornersby means of a olt 8. The point 5 is mounted at the lowerid of a shank 9, having a shoulder 10 which tter spaces said point a distance removed rom the shank to form a slot in which the ivoted ends of the wings are received. The ide edges of the point are parallel. The olt passes through the point 5 and the iank 9, whereby the wings are also pivotlly connected thereto. The wings have urved slots 11 through which the bolt 8 asses, which permits the wings to be adusted and set so that their edges will coinide with the diverging edges of the points 5 shown in Fig. 3, or to extend to the upper ml of the parallel side edges of the point 5 Specification of Letters latent.

PLOW-SWEEP.

Patented Nov. 2, 1909.

Application filed September 17, 1908. Serial No. 453,446.

as shown in Fig. 1. By thus changing the position of the wings, the sweep is adapted for different kinds of work.

The wings are held in adjusted position by means of a bolt 12 which passes through the shank 9 and through curved slots 13 in the wings near the upper ends thereof. A nut 14 screwed on the bolt securely holds the wings at adjustment, and upon loosening said nut, the wings may be spread apart or closed together as desired to suit the character of the work.

The sweep can be applied to any ordinary plow by fastening the shank 9 by means of the bolt 12 to the stock thereof. The parts comprising the sweep are few and simple which makes it easy and cheap to manufacture, and by the adjustment herein described the sweep is made to effectually serve the purpose for which it is designed.

What is claimed, is

A plow sweep comprising a shank pro vided with a forwardly extending offset at its lower end, a point on said offset in parallel relation to the shank and extending above the offset portion, a pivot pin extending through the upper end of the point and shank, a pair of wings each provided with an arcuate slot at its lower end having its center of curvature above the slot and adapted to receive said pivot pin and a second arcuate slot at its upper end having its center of curvature below the slot, and a bolt passing through the arcuate slots in the upper end of the wings and adapted to hold said upper ends in adjustment.

In testimony whereof, I affix my signature, 80 in presence of two witnesses.

SAMUEL H. CARPENTER.
