CULTIVATOR ARCH AND COUPLING.
Application filed September 30, 1921. Serial No. 504,512.
Be it known that I. O'scaa T. Honson, a
citizen of the United States, residing at Tolbert, in the county of lVilbarger and State of Texas, have invented new and useful Improvements in CultivatorArchesand Couplings, of which the following is a speci fication.
This invention has relation to improvements in the control of gangs on cultivators of the pivot frame and pivot axle classes; the primary object of which is to utilize the principle brought out in my former application whose serial number is 449,095, in a more effective manner by simplifying the construction generally and reducing the number of working parts. The more specific objects are to combine the function of the spread arch with that of the couplings thereby eliminating the spread arch, and to provide a front arch which will eliminate certain castings carried by the arch which it replaces.
l accomplish these objects by the mechanism illustrated in the accompanying drawing in which similar numerals refer to simi lar parts throughout the different figures, and in which- Figure 1 is a perspective view of the improved arch and couplings, the front part. of the gangs, and part of the supporting axle carrying the lever, and connections by means of which the spacing is controlled; Figure 2 is a section cut by the plane A B C passing through the axis of the pin 13 and the gang 14; Fig. 3is a top view of the crank arms 16 16 when disconnected.
Referring to the drawings in detail, the improved front arch consists of the strips 1 l and the angle irons 2 2' and 3 which are fastened rigidly to said strips by the bolts or rivets 4 4. The angle irons 2 2 and 3 are provided with openings in which the shafts 5 5' are journaled. The openings 6 6 7 7 8 8 and 9 are adapted for the purpose of connecting the improved arch to the other parts of the frame in the same manner that the openings which were similarly distributed and carried by castings clamped to the replaced arch were used, (which will be obvious to anyone familiar with the pivot frame cultivator). When attaching this arch, which is of general application, to the pivot axle cultivator it may be necessary to drill other openings in the angle irons 2 2 and 3 or the strips 1 1.
The extension 10 is rigidly fastened to the angle iron 8 for the purpose of shifting the point at which the arch is pivoted. In some cases this extension may be eliminated and the arch pivoted directly on the angle iron 3. The function of this extension is to allow the arch to operate in a vertical position where the improved couplings operate more etliciently, whereas the top of the replaced arch is often inclined to the rear.
The couplings are the, double hinge joints by means of which the gangs 14 14 are fastened to the frame. For convenience of manufacture the right hand coupling is made of the several parts embracing the crank arm 16, the shaft 5, the casting 11, and the pin 13 all of which are rigidly fastened together forming a solid body. The crank arm 16 is set screwed to the shaft 5, said shaft is riveted or set screwed to the casting 11, and said casting is clamped to the pin 13 by the bolt 12. In like manner the left hand coupling is formed. The gangs 14 14 (of which only the front parts are shown) are pivoted to the couplings by the castings 15 15 such that they may be raised or lowered by swinging vertically about the pins 13 13. The bearings 22 22 and the castings 15 15 are provided with threads by means of which said bearings are adjusted on the conical ends of the pins 13 13 after which the bolts 21 21' are tightened. The gangs 14 14 may swing laterally with the couplings since the couplings are journaled in the angle irons 2 2 and 3.
The crank arms16 16 are connected by the bolt 23 which makes the gangs rigid with regard to swinging laterally except when the spacing is being varied. Crank arms 16 is provided with a slot 26 in which the bolt 23 works said slot being long enough to provide for any variation in the spac mg.
The rod 17 the lever 18 and the quadrant 19 fastened to the supporting axle 20 furnishmeans for controlling the spacing of the gangs. The supporting axle 2O including the wheel journal 24 may be of the usual construction, with the exception that that an opening for the bolt 25 is provided.
It is understood that if desired the usual spread arch may be used in lieu of the rod 17, the lever 18 and the quadrant 19 which Will cooperate with the improved arch and couplings.
Having thus described my invention I claim,
'1. An arch for cultivators. in combination with the cultivator, said arch having parallel, vertically disposed shafts adjacent the arch, the upper ends oi the shafts pivoted to the cross member of the arch; an arm adjustably connected to the upper end of each shaft, said arms pivotally connected at their meeting points to a rod with an operating crank; the lower ends of said shafts atfixed to castings and means for connecting the castings to the end of the cultivator beams; the arrangement being such that manipulation of the operating rod will swing the arms in a horizontal plane to rotate the shafts and swing the cultivator beams or gangs toward or away from each other. I
2. An arch bar for cultivatorsin combination with the cultivator, with vertically 'cultivator beam couplings; the arrangement of the device adapted to cause the cultivator beams or gangs to be swung toward and away from each other when the operating 'rod is moved to swing said arms and rotate the vertical shafts; and means for locking the arms and shafts in a plurality of positions. A
In testimony that I claim thetoregoing as my own I afiix my signature in the presence of two witnesses.
