DISK-HARROW ATTACHMENT.

Specication of Letters Patent.

Application led February 15, 1909.

Patented Aug. 24, 1909.

Serial No. 477,894.

To all whom it muy concern:

Be it known that I, VICTOR E. HULCE7 a citizen of the United States, residing at Riverside, in the county of Riverside and State of California, have invented new and useful Improvements in Disk-Harrow Attachments, of which the following is a specification.

This invention relates to an attachment adapted to render possible the adjustment of the working angle of the disks without the necessity of demounting any of the parts as has heretofore been the case. In working under differing conditions it is necessary for the best results that the angle which the disks make with the line of advancement of the harrow should also be varied. In the constructions heretofore used it is necessary to stop the use of the harrow and to loosen some of the parts to make the desired adjustments, and this is not only inconvenient in that it entails a loss of time but also in that the adjustment cannot be made so accurately as it can be made with my new attachment. lith the new attachment the angle of the disks may be changed to suit the needs of any particular case while the harrow is in operation, the elfect of the adjustment being thus readily noted and the final adjustment being therefore made more accurately.

In particular the invention comprises a construction which is solid in its support of the disks and which turns on a simple pivot which is not directly over the disks. There are other points of construction which allow of a convenient adjustment of t-he parts and these will appear in the following'.

In the accompanying drawings; Figure l is a perspective view of a disk harrow equipped with my improved attachment. Fig. 2 is an enlarged plan view of one of the 'sets of disks and its mounting. Fig. 3 is a detail section taken on line 3 3 of Fig. 2. Fig. 4 is a detail section taken on line 4:*1 of Fig. 2.

Referring more particularly to the drawings, 5 designates the main frame of the harrow which is shown in conventional style as the particular configuration or operation of the frame does not have any bearing on the present invention. The front portion of the frame is supported on wheels 6 and the usual arrangement 7 is provided for the drawing of the harrow by horse or other power. A seat 8 is provided for the operator, this seat being suspended on a spring support over the rear part of the frame. Attached to the rear end of the frame is a transverse bar `9 upon which the harrow disks l0 are mounted. In the usual construction now in use the disks are affixed to the bar in a rigid manner. My invention here interposes a pivotal joint by means of which the working angle of the disks may be changed as is indicated in Fig. 2. The disks are mounted on shaft 1l which in turn is mounted in bearings l2 on the ends of yoke 13. This yoke is placed horizontally and its center is near bar 9 on the rear end of the harrow frame.

Secured by clamps 1t to bar member l5. A bolt 16 passing vertically through this member supplies the pivot for a swinging clamp member 1T, the member having extensions 1S which pass around the bar 9 and allow sufficient space between the body of the clamp member and the bar for the turning of the member. The outer face of the clamp member is toothed as at 19 and the correspondingly toothed face of an adjustable shoe 2() bears against it. On its outer face the shoe is provided with a horizontal slotin which yoke 13 is partly embedded so that the yoke is forced to turn with the shoe. The whole construction is held together by a pair of bolts 2l which pass through the clamp member and shoe and a strap 22 outside the yoke. For the passage of the bolts through the clamp member only holes of nominally the bolt diameter are provided so that bolts have no relative movement therewith. In the shoe, however, elongated slots '23 are provided so that it may have a rotating movement on the clamp member. By means of adjusting the shoe the horizontal position of the yoke and of the disk shaft may be adjusted. i

Mounted on the yoke at each side of its center is a clamp 24 composed of two right angled pieces 25 held together by bolts 2G at t-he top and bottom. At the top the clamps surround and rigidly grip the yoke 9 is a pivot' 13 and at the bottom a bar 3() is secured bes tween their horizontal ends. Bar 30 projects inwardly and at its end connects with a rod 3l by the longitudinal movements of which the position of bar 30 and the yoke carrying the disks is adjusted. It will be seen that the length of the bar 30 may be varied so that the amountof movement of the disks for a given longitudinal movement of rod 31 may be thereby varied. Rod 31 extends forwardly along the frame of the harrow and connects to the ldownwardly projecting end 32 of hand lever 33 mounted at 34 on a sector. This sect-or is toothed in the usual manner and the standard device i'sprovided on the lever to set it on the sector at any desired point. By adjusting the lever it is seen that the working angle of the disks may be variedl at will and that when the lever is set in position the disks will also be set.

In the machine illustrated in the drawings there are two sets of disks, the mechanism being the same for both sets. It is obvious that there may be as many sets as is desired, the mechanism above described being applied to each ofthe sets. Each of the sets may be adjusted independently of eachV other and this is seen to be an advantage as it is sometimes undesirable to have all the disks at the same angle.

Having described my invention, I claim 1. In a disk harrow construction, a main frame having a transverse bar at its rear bolts holding the shoe, disk frame and clamp member together, clamps mounted on the disk frame and projecting below the same,

an adjustingbar secured in the lower ends of the clamps, a rod attached to one end of the adjusting bar, and manuallyV operated means to move the bar.I

2. In a disk harrow construction, a main frame having an operators seat thereon', a transverse bar on the main frame at the rear end thereof, a pivot member adjustably mounted on the transverse bar, a vertical pivot carried by the member, a clamp member mounted on the pivot toV swing in a horizontal plane, the clamp member projecting rearwardly from' the pivot and having a vertical roughened surface at its rear end, a shoe with a roughened face adapted to engagejthe j roughened surface in the clamp member, the shoe having a normally horizontal groove in its rear face, a horizontally disposed U- shaped disk frame fitting into theV groove,`a ,strap bearing against the disk frame, bolts passing through the strap and secured to the 1clamp member, clamps mounted on the disk frame and extending downwardly therefrom, an adjusting bar adjustably secured in 'the clamps below the disk frame, a rod attached to one end of the adjusting bar, and a hand lever mounted on the main frame of gthe harrow adjacent the operatorsseat and connected to the rod.

In witness that I claim the foregoing I have hereunto subscribed my name this sixth day of February 1909.
