A principle object of the present invention is to provide a carrier comprising a frame which allows each individual rotary hoe to work on independent spring tension.
Another object of the present invention is to provide a carrier wherein each individual rotary hoe working on spring tension thus is allowed to perform its full function of breaking up the crust and still not effect the underlayer of the earth.
Still a further object of the present invention is to provide a floating carrier wherein flexibility permit each row to work near the same depth even when therows are uneven in depth.
Other objects of the present invention are to provide a floating carrier which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:
FIG. 1 is a top plan view of a floating carrier incorporating the present invention, and
FIG. 2 is a side cross-sectional view taken on the line 22 of FIG. 1 and shown relatively enlarged.
Referring now to the drawing in detail, the reference numeral represents a floating carrier according to the present invention wherein there is a frame 11 of generally rectangular configuration and wherein there are a front beam 12 and a rear beam .13 in parallel spaced-apart relation thereto, the front and rear beams each being made of 3-inch angle iron and being 13' feet 10 inches in length.
The opposite ends of the front and rear beams 12 and 13 are enjoined by a k by 3-inch flat iron 14. The members l2, l3 and 14 are rigidly welded together into a unitary structure, as shown in FIG. 1.
A hitch structure 15 extends forwardly of the front beam 12, the hitching structure 15 including a pair of 3-inch by 24- inch-angle irons 16 together with pins welded to the front beam, and a pair of by 3-inch flat irons welded to the angle iron near the pin so to extend upwardly 19 inches, as shown at The frame 1 1 supports a plurality of sets 18 each set 18 being comprised of a pair of bars 19, each of the bars 19 being supported pivotally free at their one ends about a pin 20 supported between a pair of blocks 21, the blocks being welded to the front beam 12, as shown in FIG. 2 of the drawing.
Each of the pair of blocks 21 is dimensioned 2% by 2% inch by B-inch thick. The blocks are spaced apart so that the end The freely depending end of the bars 19 are provided with an opening 22 transversely therethrough so that a rotary hoe may be individually supported by each bar 19.
Intermediate the opposite ends of the bar 19, a pin 23 is secured thereto, the pin 23 being fitted with a bushing, and the bushing being fitted into an eye formed at the lower end of a vertically depending rod 24.
The upper portion of the rod 24 extends through an opening 25 formed in the rear beam 13, and a compression coil spring 26 is fitted around the rod 24 and positioned below the rear beam 13 so that the upper end of the spring bears there against. The lower end of the spring 26 bears against a lower collar 27 secured by a setscrew 28 or the like to the rod 24.
Another collar 29 is secured by means of a setscrew 30 to the upper portion of the rod 24 which extends upwardly of the rear beam 13.
In operative use, the frame will allow each individual rotary hoe to work on spring tension. This lets each rotary hoe to perform its full function of breaking up the crust and still not effecting the material below. The flexible frame lets each row to work near the same depth even when the rows are uneven in depth.
What I now claim is:
1. In a floating carrier, the combination of a frame, means for hitching said frame to a tractor, and said frame supporting a plurality of bars, each of said bars being individually spring loaded, each of said bars supporting a rotary hoe, said springloaded bars each letting said rotary hoe to perform its full function of breaking up earth crust, said frame comprising a rectangular member having a pair of parallel spaced-apart front and rear beams made of angle iron, the opposite ends of said angle irons being enjoined to a pair of side flat irons welded there to, and said means for hitching to said tractor comprising a pair of forwardly extending angle irons supporting a pair of flat irons so to form a hitch extending forwardly of said rectangular frame, each one of said bars comprising one of a pair of bars forming a set, a space between said sets that is larger than a space between said bars within each set, said frame-supporting a plurality of said sets, each of said bars being attached pivotally free at its one end to a transverse extending pin supported between a pair of blocks affixed to said forward beam of said frame, said beam extending diagonally rearwardly down from said supporting pin, a rear end of said bar having an opening transversely there through for securement of said rotary hoe there to, and an intermediate portion of said bar having a pin secured there to, said pin being fitted into a bushing supported at a lower end of a rod provided with an eye at the lower end thereof, said rod extending vertically upwardly through an opening through said rear beam, a compression coil spring being positioned under said rear beam and fitted around said rod so that an upper end of said spring bears against the under side of said rear beam, a lower end of said spring bearing against a lower collar secured by a setscrew around said rod, and an upper oollar being secured by a set screw to an upper portion of said rod extending upwardly of said rear beam.
