' RIDING SPRING-TOOTH HAiaR ow.

SPECIFICATION forming part of Letters Patent N0. 781,100, dated January 31 1905.

Application filed October 8,1904:. Serial No. 227,720-

To all whom it may concern.-

Be it known that LOHARLEs S. SHARP, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Riding Spring Tooth Harrows, of which the followingis a specifiin contact with the wheels; and the object of my invention is to overcome this defect in a simple and effective manner, as will be hereinafter shown. r

The sulky used is more fully described in my application filed December 21, 1897, Serial No. 662,802.

Referring to the drawings, Figure 1 is a plan view of my improved riding-harrow, and Fig. 2 is a longitudinal section on the line X X of Fig. 1. v

My improved harrow is composed of two sections hinged together, the metallic frames A beingbent so as to form side and front bars. Rocking tooth-bars B, their ends bent at right angles, are pivoted to the side bars of the harrow-frames at a. Each tooth-bar B has spring harrow-teeth secured to it in any suitable manner. Midway between the side bars of each harrow-section are bars 0, secured to the front of the frames A A. Standards Z) are secured to and project upwardly from the tooth-bars B and are pivoted to the central bars Cat 6. The upper ends of the standards I) are pivoted to horizontal bars a, which are parallel with the bars C. Set-levers of the usual construction are rigidly attached to the rear standards and provided with locking-dogs, which engage with the teeth of quadrants b on the bars a. Shoes D are pivotally attached to the front of the harrow-frames A A.

Secured tothe front tooth-bars are rearwardly-projecting brackets clftowhich are pivotally connected bars cl, rigidly attached at their rear ends to the sulky or. riding part of the harrow. The sulky straddles the'inner frame-bars of the harrow, the wheels being 4 located between the rear tooth-bars and approximately equidistant therefrom.

When the tooth-bars B are rocked to raise the harrow-teeth out of engagement with the ground, it is obvious that their movement would be limited by thetooth-loars immediately in front of the wheels coming in contact with the latter. By pivotally attaching the bars d to the rear of the front tooth-bars, preferably to a bracket secured to the toothbars and projecting rearwardly, when the tooth-bars are rocked the sulky is moved to the rear at the same time, as shown in dotted Having thus described my invention, what I claim, and desire to cover by Letters Patent', is I 1. A rocking-tooth-bar harrow,in combination with a sulky therefor, and means connecting the harrow and the sulky to move the latter when the tooth-bars are rocked.

2. A rocking-tooth-bar harrow, in combination with a sulky within the harrow,and means connecting the harrow and the sulky to move the latter when the tooth-bars are rockedf r 3. A rocking-tootl1barharrow, in combination with a sulky within the harrow, and means connecting the harrow and the sulky to move the latter coincidently with the movement of the tooth-bars.

4:. Arocking-tooth-loar harrow, in combination with asulky within the harrow, and means connecting the sulky with the forward toothbars of the harrow to move the sulky'when the tooth-bars are rocked.

5. The combination with a rocking-toothbar harrow, of a sulky within the harrow, having wheels between the rear tooth-bars, and means connecting the harrow and the sulky to maintain the relative position of the wheels and the rear tooth-bars when the toothbars are rocked.

6. The combination with a rocking-toothbar harrow, of a sulky within the harrow, having wheels between, the rear tooth-bars of the harrow and approximately equidistant therefrom, and means connecting the harrow and the sulky to maintain the relative position of the wheels and the rear tooth-bars when the latter are rocked.

7 The combination with a sectional rocking-tooth-bar harrow, of a sulky within the harrow, having wheels between the rear toothbars of the sections, and bars connecting the harrow and the sulky, the latter moving coincidently with the movement of the toothbars.

8. The combination with a sectional rocking-tooth-bar harrow, of a sulky within the harrow, having wheels between the rear toothbars of the sections and approximately equidistant therefrom, and bars connecting the harrow and the snlky to maintain the relative position of the wheels and tooth-bars at any position of the latter.

9. The combination with a sectional rocking-tooth-bar harrow, of a sulky within the harrow, having wheels between the rear toothbars of the sections and approximately equidistant therefrom, and bars connecting the forward tooth-bars of the harrow and the sulky to move the latter when the tooth-bars are rocked.

10. The combination with a sectional rocking-tooth-bar harrow, of a sulky within the harrow, having wheels between the rear toothbars of the sections and approximately equidistant therefrom, and bars attached to the sulky and pivotally secured to brackets on the forward tooth-bars of the sections.

In testimony whereof I hereunto set my hand, this 21st day of September, 1904, in the presence of two attesting witnesses.

CHARLES S. SHARP.
