1 Claim. 1

This invention relates to new and useful improvements in attachments for farm implements.

Objects of this invention are to provide means for selectively receiving stalk cutter assemblies and roller units; to provide means for carrying said cutter and roller assemblies; to provide means for lifting said roller and cutter assembly means; to provide a versatile device of the character described, capable of performing the above mentioned objects as well as other ancillary objects.

Other objects and features of novelty shall become apparent to those skilled in the art, in following the description of the illustrated preferred embodiment of the present invention, depicted in the accompanying drawings, wherein:

Figure 1 is an elevational side view of the preferred embodiment of the present invention, showing said embodiment operatively connected to conventional elements of a tractor;

Figure 2 is an elevational plan view of the invention disclosed in Figure 1;

Figure 3 is a transverse sectional view of the cutter assembly shown in Figure 2 and taken substantially on the line 33 of Figure 2 and in the direction of the arrows;

Figure 4 is a transverse sectional detailed view taken substantially on the line 4-4 of Figure 2 and in the direction of the arrows;

Figure 5 is a sectional view of the detail of construction illustrated in Figure 4 and taken substantially on the line 55 thereof and in the direction of the arrows; and,

Figure 6 is an elevational plan view of the roller assembly forming part of the present invention, showing portions broken away in section to illustrate details of construction.

Referring now in detail to the illustrated preferred embodiment of the present invention, like reference characters are used to designate similar elements. A frame member, preferably rectangular in configuration is generally indicated at 10 and consists of

sides

2 and 3 and

ends

4 and 5. The sides and ends are of angle iron construction, each having a horizontal flange 6 and a vertical flange 1. A tongue, noted by the general character I2, is rigidly secured to the said frame member Ill by any conventional means, preferably welding, riveting or the like. The construction of the said tongue may be a simple channel-iron member if so desired, having legs l4 and I6 extending upwardly thereof. Of course, this detail of construction may be provided by simply utilizing a pair of rods in place of the said channel-iron. A pair of rods 18 extend perpendicular from the said channel member and a pair of gusset plates 20 are provided between the legs l4 and i6 and the upwardly extending rods 18. The plates serve their usual conventional purpose, namely, to add rigidity and strength to the construction. The partially annular connecting rod 22 is secured to the said rectangular frame member If] and extends arcuately over said member H3. The terminal portion of said rod 22 is provided with bifurcations 24 adapted to be secured to the said upwardly extending rods l8. For ease in manufacture, all of the rigid joints may be of welded or brazed construction.

A fish plate 26 is then provided with 2. rolled bearing member 28 at one end thereof. A shaft or pin 30 is received in said bearing member 28 and a pair of

links

32 and 34 respectively are pivotally disposed on alternate ends thereof. The opposite ends of said

links

32 and 34 are pivoted to a suitable anchor means 36 which may be rigidly secured to the axle housing 38 of a conventional tractor. The said fish plate 25 is secured under the tongue l2 by any suitable means, and is preferably removably secured thereto. A pivot pin 40 is passed through. suitable apertures in the channel member and in the fish plate. A pair of slots 42 are provided in the fish plate and channel member and a limiting pin 44 is passed therethrough. It is apparent that by this construction, limited pivotal movement of the frame member It] may be provided relative to the fish plate 26.

It can appreciated that it is not always desir- V able to have any farm implement operative at all times. Accordingly, the following construction is provided for raising and lowering, selectively, the frame member 10.

The conventional actuating means, which is usually hydraulic, is indicated at 45 in the portion of the illustrated tractor. As is usual in this type of construction, the arms 48 rotate thereby lifting the bifurcated crank 59 in an arcuate path of travel. Pitman rods 52 are received in the bi-= furcations 54 and at substantially the centerof said links 34. Of course, as is usual with pitman members, each end thereof is pivoted by some suitable means such as rivets 55. It is apparent that upon actuation of the hydraulic actuating mechanism 46, the perch will be urged in. a selected direction.

The conventional element 53 of said hydraulic actuating mechanism is provided with a shackle BE) on the piston rod thereof. A connecting rod 62 is disposed on one of the pivot pins of said ered.

shackle and between the said bifurcations 24, described 'hereinbefore. A removable pivot pin 64 is passed through said bifurcations 24 and a suitable aperture in the connecting rod 62. It is quite apparent from an inspection of Figures 1 and 2, that upon actuation of the said element 58, the upper end of the said tongue and consequently the frame it] will be selectively raised and low- Substantially at the longitudinal center of ,said frame I is the center line and axis of rotation of selective conditioning members, either stalk cutting assembly or roller assembly. It is noted that other assemblies may be utilized if so desired, for specific jobs or operations. A pair of conventional U-bolts 70 form parts of bearings and are passed through suitable apertures in the said frame and are oppositely aligned. Bearing blocks '12 are adapted to be received on the legs of said U-bolts, abutting the actual frame member E0 and abutting a suitable axle or shaft 14. Any suitable conventional means may be used to secure said U-bolts in said frame l0. However, the preferable construction is simple conventional nuts "l6. In the stalk cutter assembly, a pair of cutter members are provided on said shaft '54. The construction of these cutter members is quite simple and will be described at this time.

A pair of circular plates 78 are held in spaced relation by cutter blades 80 which are removably secured to suitable blocks 82, secured on said plates '53. A hub 84 may be riveted or otherwise secured to each of said plates in order to provide a suitable durable bearing surface. Limitingthrust bearings or collars 86 are provided at each side of said circular plate for retaining the cutter members in a predetermined selected position. B this means, the blade and cutter assembly may be adjusted axially of the said shaft '54. The construction of the thrust bearings may be simple collars as disclosed at 86 with set screws 88 therein.

A second conditioning means which may be used in the said frame i0 is disclosed in Figure 6. This means is a cylindrical roller 90 which may be used for various rolling operations. A tube or sleeve 92 extends longitudinally within said roller and bearings 94 are provided at each end of the bore of the said sleeve 92. It is quite apparent that the shaft Hi may be inserted in the bearings 94 and said shaft may be secured within said frame as described hereinabove. An aperture 96 is provided in one wall of the said roller 90 and a removable plug 98 is provided therein. Ballasts, such as sand, water and the like may be provided in said cylindrical roller to add weight thereto.

I claim:

A farm implement comprising a substantially rectangular frame consisting of two sides and two ends, said sides and ends having horizontal and vertical flanges, bearings carried by and depending from the horizontal flanges of said ends, a farm implement tool which includes a shaft, said shaft being disposed in said bearings, a tongue extending from one of said sides, said tongue including an upwardly extending rod, a horizontal shaft secured to said tongue and disposed below said upwardly extending rod, lifting links secured to said horizontal shaft, and a connecting rod ecured to the side of said frame opposite the side to which said tongue is attached and secured to part of said upwardly extending rod.
