- REDFORD PATENTEDJAHBO I975 SHEU 3 [IF 3 HARROW HINGE LOCKING DEVICE BACKGROUND OF THE INVENTION
- This invention relates to foldingwing implements and particularly to novel means for attaching the wing section to the outer end of the main section.
- an object of the AUTOMATIC DISK present invention is the provision of simple and efficient means for hingedly attaching a wing extension to the main tool-carrying section of an implement.
- Another object of the invention is the provision, in
- an implement such as a disk harrow having foldable wing sections, of simple and economical means for locking the wing sections to the main sections when the wings are returned from the folded inoperative position, to their aligned operating position.
- FIG. 1 is a perspective view, with parts removed, of a folding wing tandem disk harrow incorporating the features of this invention
- FIG. 2 is an enlarged detail in perspective illustrating the means by which one of the wing sections is connected to a main implement section;
- FIG. 3 is a detail in side elevation of one of the wing gang sections released from the associated main section and beginning its arc of swinging movement about the axis of its pivotal connection to the main gang section;
- FIG. 4 is a'view similar to FIG. 3 after the wing section has swung. 180 to its fully folded inoperative position above and generally parallel to the main section;
- FIG. 5 is a plan view of the structure shown in FIG. 2;
- FIG. 6 is a sectional view taken along the line 6-6 of FIG. 2.
- FIG. 1 The implement shown in FIG. 1 is a wheel controlled tandem disk harrow comprising front and rear relatively angled left and right hand disk gangs 10 and 11,
- disk gangs 10 and 11 are mounted on the supporting frame 13 by conventional means, not shown, accommodating angular adjustment of the gangs, and that the gangs are substantial duplicates with the disks 12 of the front gangs facing outwardly while those of the rear gangs face inwardly in a manner well known in the art.
- the implement is supported and raised to a transport position by the provision of a transverse rock shaft 15 mounted on the frame and having at its ends crank arms 16 upon each of which is mounted a pair of wheels 17.
- Shaft 15 is rockable in well known manner by suitable power transmission means such as a hydraulic cylinder, not shown, receiving fluid under pressure from a source on the tractor by which the implement is propelled. Rocking the shaft 15 to swing the wheel carrying arms 16 vertically raises and lowers the implement.
- Each of the gangs l0 and 11 has a main section 18 and a wing section 19, and main section 18 comprises a horizontal beam 20, rectangular in cross-section, from which disks 12 are suspended by hangers 21 as indicated in FIG. 1.
- the outer end of beam 20 is seated in a channel shaped member 22 a portion of which projects from the end of beam 20, member 22 having a transverse portion 23 attached to the beam by a bolt 24, and sides 25 secured to the beam by bolts 26.
- a pair of upstanding brackets 27 are affixed, as by welding, to
- Outer disk gang section 19 comprises a rectangular beam 30 in horizontal alignment with main beam 20 in the operating position of FIG. 1 and from which the disks are also suspended by hangers 21.
- the inner end of wing beam 30 is seated in overlapping relation to the projecting bottom portion 23 of channel member 22 between the sides 25 thereof, as indicated in FIGS. 2 and 6, and has affixed, as by welding, to opposite sides thereof upwardly extending and inwardly angled lugs 31, the upper ends of which are mounted on hinge pin 28 to accommodate pivoting of wing section 19 in a vertical plane about the axis of the hinge from the extended, operating position of FIGS. 1 and 2 to the folded inoperative position of FIG. 4 generally parallel to main section 18.
- Wing section 19 for each of the gangs 10 and 11 is locked in its operating position to the main section 18 by the provision of a U-shaped rockable member 32 having a transverse bight portion 33 and upwardly directed arms 34 and 35 pivotally mounted medially of their ends on the respective lugs 31 by pivot bolts 36 and 37 and removably secured by nuts 38.
- a spacer 39 is provided on bolt 36 between arm 34 of rockable member 32 and the adjacent lug 31, and it will be observed in FIG. 2 that in the operating position of wing section 19 the angled lower edges of lugs 31 are engageable with a beveled upper edge 40, shown clearly in FIGS. 3 and 4 formed at the outer projecting ends of the sides 25 of channel member 22 to act as a stop or abutting means limiting downward swinging of wing beam 30 relative to main beam 20.
- the bight portion 33 of rockable member 32 in the operating position of wing section 19, as clearly shown in FIGS. 2 and 6, is in underlapping relation to the transverse portion 23 of channel member 22 to lock the main and wing sections together and is automatically rocked to its locked position by the provision of a torsion spring 41 coiled around bolt 37 between lug 31 and arm 35.
- One end 42 of spring 41 is anchored in an opening 43 provided in the portion of arm 35 projecting above bolt 37, and its other end 44 bears against the upper edge of the adjacent lug 31 to yieldably bias member 32 to rock in a counterclockwise direction as viewed, for example, in FIG. 3.
- helper springs such as indicated at 45 in FIG. 1 for the right hand rear disk gang 11.
- helper springs function in a manner well known in the art to facilitate manual folding and unfolding of the wing sections.
- a folding wing implement including a main beam and wing beam, an upstanding bracket affixed to said main beam, and upwardly extending lug affixed to said wing beam, hinge means comprising a pivot pin interconnecting the upper ends of said bracket and said lug to accommodate pivoting of the wing beam from an extended operating position in horizontal alignment with the main beam to a folded inoperative position relative thereto, abutting means on said main and wing beams, said respective abutting means engaging when the wing beam is in the extended operative position to prevent further downward pivotal movement of the wing beam relative to the main beam, releasable means for locking the wing beam in its extended operating position comprising, a rockable member pivotally connected to said wing beam having a lower horizontal portion in underlapping engagement with said main beam when said wing beam is in the operating position, and an upright lever portion for rocking said rockable member out of underlapping engagement with said main beam, and yieldable means comprising a spring operatively connected between said upwardly extending
