CULTlVATOR A ND HARROW.

.SPECIPICATION forming part of Letters Patent No. 387,856, dated August 14, 1888.

Applicaiion filed April 12, 1888. Serial No. 270,437. (No model.)

To all whom it may concern.-

Be it known that I, HENRY G. OADY, a citizen oi the United States of America, residing at Pine Bluff, in the county of J eii'erson and State of Arkansas, have invented certain new and useful improvements in Harrows, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in harrows, having reference more particularly to the class of springtooth barrows.

The object of the invention is the provision of simple and highly efficient means for securing together the draft or cross bars of a harrow-irau'ic and for attaching the barrow-teeth thereto, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of aportion of aharrow with my invention applied thereto. Fig. 2 is an inverted view thereof. Fig. 3 is a detail sectional view, and Fig. 4 is a detail perspective view.

Referring to the drawings, A designates a portion of a barrow-frame, composed, preferably, of two side sections, a a, between which is the longitudinal bar a, to which are secured the convergent ends or crossing portions of the draftbars a".

B is asecuring plate or head provided with a central aperture for insertion of a vertical securing-bolt, 6. From the upper surface of this securing plate or head projects a circularly-arranged series of lugs or projections, b, a uniform space or distance being observed between each two of said lugs or projections, as shown. The undersurface of this securing plate or head has projecting therefrom four ears or shouldersfl between the opposite sides of each two of which is formed a groove or recess. In these grooves or recesses,between the ears or shoulders I), are held the convergent crossed ends of the wings a a the same being secured therein by means of the bolt 7).

In thcundcr side of the drai'tbar a are found two holes or apertures, 11* I), wherein are designed to project two opposite lugs or projections, 6'. The securing plate or head is held firmly against the underside of this longitudinal bar by the belt I), which is fitted with a nut on its upperend, as shown. By this means the wing or the cross can be rcadil y and easily secured at the desired angle, the same being changed when necessary by simply loosening the bolt and turning the plate or head, as is obvious.

G C designate the s )ring-teeth, which are secured to the under side of the draft-bars by means of plates D, which are provided with slots at for the end of the teeth to project through and to permit of thcadjustment there of when necessary.

Plates D are each provided with divergent slots (1 d, through which holding-bolts d are passed, whereby said plates can be held at the desired angle. A single belt, at", is passed through the front end of each plate, as shown.

From the foregoing description it will be seen that my invention comprises simple and efficient means for readily and easily securing the parts of a harrow, cultivator, or plow to its beam and at the desired angle, and also for adjusting and holding each spring-tooth in the desired position, and the device embodies advantages in points of simplicity, durability, and general efficiency.

I claim as my invention- 1. As an improvement in harrow-frames, the securing head or plate having a series of up Wardly-projecting lugs and the cars or shoulders formed on the under side of said head or plate, substantially as shown and described.

2. As an improvement in barrows, the central bar having holes or apertures in its under side, the securing plate or head having a series of upwardly-projecting lugs, and the central vertical bolt, substantially as shown and described.

3. In a harrow-franie having draft and cross bars, the securing plate or head having on its under side ears or shoulders, between which are grooves or recesses, and the central bolt passed through coincident apertures in said bars and plate or head, substantially as shown and described.

4. The conibinatioinwith the draft and cross bars and the longitudinal bar, of the securing plate or head having a series of upwardly-projecting lugs and ears or shoulders formed on In testimony whereof I affix my signature in its lower surface, and the securing-bolt, subpresence of two witnesses. stantially as shown and described.

5. As an improvement in spring-tooth har- HENRY G, GADY. 5 rows, the heads having each divergent slots,

and a slot or aperture through which the end Witnesses: of the spring-tooth projects, substantially as J W. PARSE, shown and described. J. W. CRAWFORD.
