Specification of Letters Patent. 1 Patented N 10, 1914.

Application filed m 1, 1914. Serial No. 848,436.

To all whom, it may concern:

Be it known that I, DALLAS L. IQEOK, a citizen of the United States, residing at Brookings, in the county of Brookings and State of South Dakota, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in cultivators, and the object of the invention is to provide a novel and improved device of this general character wherein the requisite action upon the soil between the adjacent rows may be effected with convenience and facility.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved cultivator whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for panying drawings, wherein- Figure 1 is a view in top plan of a cultivator constructed in accordance with an embodiment of my invention; Fig. .2 is a rear elevational view of the device as illustrated in Fig. 1; Fig. 3 is a side elevational view of the device as herein embodied; Fig. l is a detail sectional view, illustrating the means herein employed for adjusting the cultivator blades or shovels; Fig. 5 is a longitudinal sectional view, showing in detail a mounting for the shovels or blades; and Fig. 6 is a sectional view taken substantially on the line 66 of Fig.

As disclosed in the accompanying drawings, 1 denotes an arch frame provided at its lower extremities with the trunnions 2, on which the supporting wheels 3 are adapted to bemounted, and operatively engaged with such member 1 is the draft rigging 4: which may be of any ordinary or preferred construction, herein disclosed as particularly adapted for a double team.

Rotatably supported by the frame 1 is the shaft 5 terminating at its opposite ends in the cranks 6, to each of which is operatively comprises two sections capable of adjustment, as indicated at 14:, whereby the free extremities of the member may be moved one relative to the other in order to co1npcnsate for different widths of rows. I also find it of advantage to interpose between the crank ends 6 in the shaft 5 and the frame 9 a buffer 15, preferablya coil spring, surrounding the link 8 whereby it will be seen that independent movement may be had by the auxiliary arch member 12 in such instances when an undue obstruction is encountered. The shaft 6 has coacting there with a conventional latch controlled lever 17 whereby sufficient rotation may be imparted to theshaft to raise or lower the auxiliary arch member 12 as the necessities of practice may require.

Disposed transversely through each end of the auxiliary arch member 12 is a tubular member 18, through which is disposed a shaft 19, on the opposed extremities of such shaft 19 are mounted the sleeves 20 to which are suitably secured the shanks 21, the opposed faces of the sleeves 20 and the tubular member 18 being of clutch formation so that the shanks 21 may be adjusted on any desired inclination, such adjustment being maintained through the medium of the clamping nuts 22 suitably engaged with the end portions of the shaft 19.

Operatively engaged with the lower or outer extremities of the shanks 21 are the cultivator blades or shoes 23 which are also operatively engaged, through the medium of the links 24, with the sleeve 25, slidably mounted upon a rod 26 projecting rearwardly from the lower extremity of the auxiliary arch member 12 and operatively engaged with such sleeve 25 is a lever 27 whereby it will. be readily perceived that the blades or shovels 23 may be adjusted one relative to the other. i I find it of advantage to have the outer end of the rod 26 provided with a From the foregoing description, it is thought to be obvious that a cultivator con structed 1n accordance with my invention 1s of an extremely simple and comparatively inexpensive nature and is particularly Well adapted for use by reason of the convenience" and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this:

between the sleeve and each of the implements, and means for impartin movement to" the sleeve longitudinally of the rod.

2. A device of the character described comprising a supporting frame, anarch member adj ustably carried thereby, rods projecting from the extremities of the arch member, a sleeve slidable on each of the rods, an agricultural implement disposed on opposite sides of: the rod, a link connection between the sleeve and each. of the implements, means for imparting movement to the'sleeve longitudinally of the rod and an agricultural implement carried by the outer end of the rod.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
