TANDEM DISK HARROW.
Application filed August 11, 1925. Serial No. 49,579.
This invention relates to improvements in agricultural implements and more particularly adapted to an improved disk harrow.
One of the important objects of the present invention is to provide a disk harrow which includes a frame, in the respective ends of which are journaled the outer ends of a pair of disk supporting shafts, the inner ends of these shafts being adjustably secured to the front side of the frame whereby the angle at which the disks are disposed may be adjusted.
A further object is to provide a disk harrow of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purposes for which it is designed.
Other objects and advantages of this in vention will become apparent during the course of the following description.
I11 the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same:
Figure 1 is a top plan view of the disk harrow embodying my invention, and
Figure 2 is a side elevation thereof.
In the drawing, wherein for purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally the frame, the same being substantially of rectangular design and in eludes the front and rear side members 2 and 3 respectively and the end members 1 and 5. The side members and the ends of the frame are secured together in any suitable manner and suitable corner braces 6 are provided in the manner as clearly illustrated in Figure 1. The frame is preferably constructed of wood although I do not wish to limit myself to this particular material, any other material being used as desired.
Secured on the bottom of each of the end members of the frame 1 is the bearing block 7, the securing means therefor being shown at 8. A metallic brace 9 extends around the bottom edge of the bearing block carried by each end of the frame and the securing means for the block also extends through the brace as is shown more clearly in Figure 2. Furthermore the respective ends of the brace are secured at the corners of the respective end members of the frame by the same fastening means employed for securing the adjaeent ends of the sides and the end members scribed.
- on the front side 2 of the frame and the rear ends of these braces are secured to the rear side of the frame. In this manner, the frame is rendered rigid.
A shaft 12 is journaled at its outer end in the bearing block 7 supported by the end member 4 of the frame 1 and is adapted for oscillatory movement therein for the purpose also to be hereinafter more fully de- A similar shaft 13 has its outer end journaled in the bearing block which depends from the other end member 5 of the frame 1 and is also adapted for oscillatory movement therein. The inner opposed ends of these shafts terminate in the intermediate portion of the frame as is obvious from the construction shown in Figure 1. A plurality of disks 14 of any conventional construction are arranged in spaced intervals on each of the shafts. The intermediate portion of each of the shafts is supported by the interconnected eye bolts or links 15 and 16 respectively, the upper end of the link or eye bolt 15 being secured to one of the arched braces 11 while the lower end of the link or eye bolt 16 is secured to each of the shafts. In this manner, the shafts 12 and 18 are supported in horizontal alignment with respect to each other.
For the purpose of moving the inner free ends of the shafts 12 and 13 forwardly or rearwardly so that the angle at which the disks are disposed may be regulated, I provide the chains 17 and 18 respectively. A pair of such chains is associated with each of the shafts and as is shown in Figure 1, the forward ends of the chains are secured to the front side 2 of the frame while the rear ends of the chains are secured to the respective shafts adjacent the respective ends thereof. The chains will further limit the rearward swinging movement of the shafts and the disks carried thereby so that when the harrow is in operation, the disks will be maintained in their proper position for engagement with the ground or soil to be harrowed.
Any suitable draft, appliance such as is shown at 20 extends forwardly from the frame 1 whereby the draft animals may be hitched to the harrow for the purpose. of moving the latter over the soil when the harrow is in use.
It will thus be seen from the foregoing description, that a disk harrow has been provided wherein the angle at which the disks are, disposed may be adjusted to facilitate the proper cultivation of the soil and simplicity in which this is accomplished will save considerable time and labor. Furthermore a disk harrow of the above mentioned character will be strong and durable yet inexpensive.
Vhile I have shown the preferred embodiment of my invention it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended I claims.
Having thus described my invention, what I claim is 1. A disk harrow comprising a substantially rectangular shaped frame, bearing blocks depending from the respective ends of the frame. a pair of shafts journaled at shaft, and means for adjustably securing the free ends of the shafts to the forward side of the frame.
2. A disk harrow comprising a substantially rectangular shaped frame, bearing blocks depending from the respective ends vof the frame, a pair of shafts journalcd at their outer ends in the respective bearing blocks and adapted for oscillatory movement therein, disks carried by each of said shafts, transversely extending braces carried by the frame, suspension means for the intermediate portions of the shaft comprising a pair of interconnected eye bolts, one of said eye bolts being secured to the adjacent brace, the other eye bolt being secured to a respective shaft, means for adjustably securing the free ends of the shafts to the forward side of the frame, said last mentioned means comprising a series of hooks arranged on the forward side of the frame, and chains secured at their rear ends to the respective shafts and adapted for engagement with the respective hooks.
In testimony whereof I aflix my signature.
EDWARD P. SI-IROYER.
