IMPROVEMENT IN COMBINED PLOWS AND HARROWS.

Specification forming part of Letters PatentNo. 176,072, dated April 11, 1876; application filed Deccmberlli, 1875.

To all whom it may concern Be it known that I, J oHN'L. SGARBROT GH, a resident of Fayetteville, in the county of Talladega and State of Alabama, have invented certain new and useful Improvements in Oombinations of Flows and Expanding Harrows; and I do hereby declare that the following is a full, clear, and exact description thereof. which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention consistsin an improved combination of a plow and expanding barrow, all

of which will be hereinafter particularly explained, with reference to the accompanying drawing,-in which Figure 1 is a perspective view of my invention, and Fig. 2iis a detail view'of the devices for adjusting the plowpoint.

A is the plowbeam. B is a supplemental beam, hinged at one side and near the rear end of beam A. To the outer end of the hinged beam B is attached one end of a metallic are, 0. From the other end of this are a series of holes c c 0, extends half the length thereof, more or less. I) is a bolt, passing through beam A in the path of arcO, through either hole 0 c 0 of which said bolt is secured, according to the desired adjustment of hinged beam B, which may be arranged at angle with beam A. E E are curved harrow-teeth, the

head, h, against the under side of beam A.

Through the longitudinal slot in head It, and also through beam A, passes a bolt, 2'. The standard G has a slot, J, extending from near its foot to near its top. Through this slot J a bolt, K, passes, and also through shank f of plow-point F. Above bolt K another bolt, K, having a large square head directly above the shank f, also passes. L L are the plow-handles, and l is an upright, Which supports them.

By means of the curved arm H, slotted head h, and bolt '5, the standard G can be adjusted and secured in a more or less vertical posi-. tion, and the depth of penetration of plowpoint F thus regulated. By loosening bolt K the point F may be raised or lowered, and in any position in which said pointis secured by bolt K. The head of bolt K is then brought directly against the top of shank f, and there firmly secured to serve as a brace against npward strain on the plow-point. The manner of expanding or contracting is obvious without further explanation. [n whatever position the hinged beam B is arranged,the curved harrow-teeth E E should be turned to coincide with point F-i. 0., pointing in the same direction.

Having now fully described my invention, I claim and desire to secure by Letters Patent [n a combined plow and cultivator, the adjustable hinged barrow-beam B, with its teeth E E, perforated adjustable are C, and beam A, in combination with the adjustable hinged and slotted standard G, plow-point F, and adjustable abutment K, substantially as set forth and described.

In testimony that I claim the foregoing as my owninventioir I affix hereto my signature in presence of two witnesses.

JOHN L. SOARBROUGH.
