Abstract
"GROUND WORKING IMPLEMENT AND DISC GANG TRIPPING MECHANISM
THEREFOR"
ABSTRACT OF THE DISCLOSURE
Individual disc gangs in a ground working implement such as a disc cultivator or the like, are hinged to the main frame for hinging movement rearwardly from the direction of travel. Each disc gang has a trip mechanism so that if any of the gangs encounter an obstruction, the individual gang trips and then returns to the preset position thus eliminating damage to the disc and/or gang as well as preventing the machine from being lifted as the disc encounters the obstruction.

GROUND WORKING IMPLE~IENT AND DISC G~NG TRIPPING MECHANIS~I
THEREFOR
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in ground working agricultural implements which inclu-de a plurality of disc gangs depending from a main frame, together with disc gang tripping mechanism.
Conventionally, the sets of discs are mounted to the frame and the depth of penetration is normally controlled by adjusting the frame and the gangs relative to the ground en-gaging wheels upon which the frame is mounted, it being un-derstood that the implement is normally pulled behind a trac-tor or the like.
If one or more of the individual discs strikes an obstruction during operation, the disc can readily be damaged ; or the gang mounting the disc can be damaged. Sometimes the entire side of the machine is lifted clear of the ground as the disc passes over the obstruction thus causing uneven depth ~ of cultivation or ground working and in some instances, skip-; 20 ped areas of cultivation or ground working.

The present invention overcomes these disadvantages by providing the individual disc gang assemblies with means to hinge them to the main frame of the implement and to pro-vide a trip mechanism for each individual gang. This means that only one relatively small section is affected if an ob-struction is engaged and this section merely hinges out of the way clear of the obstruction until same has been passed where-upon the spring loaded trip mechanism returns this individual gang assembly to the original preset position.
Furthermore, if damage does occur to an individual disc gang assembly, it is readily removed from the machine for repair and/or replacement.
In accordance with the invention there is provided, a disc gang assembly for ground working implements which in-clude a frame; said disc gang assembly comprising in combina-tion a gang frame, means hinging said gang frame to the frame of the implement whereby said disc gang assembly can move from a ground working position towards a fully tripped position rearwardly of said frame, and vice-versa, and a trip assembly operatively connected between said frame and said gang frame normally maintaining said disc gang assembly in the ground working position, said trip assembly including supporting structure secured to the frame of the implement, a bell crank component pivotally supported by one end thereof within said ~.

DETAILED DESCRIPTION
Proceeding therefoxe to describe the invention in detail, reference to the drawings will show in fragmentary form, a ground working implement generally designated 10 such as a disc cultivator or the like.
This implement includes a frame generally designated ll having a hitch 12 (shown in fragmentary form only) extend-ing forwardly therefrom by which the implement may be secured to a tractor or the like. Ground engaging wheel assemblies h~
13 extend downwardly from the frame 11 and are pivotally secured to the frame so that by raising and lowering the frame relative to the wheel assemblies 13 by conventional means (not illustrated), the disc gangs collectively de-signated 14, may be adjusted as to depth of penetration be-low the ground surface 15.
The disc gang assemblies 14 consist of a plurality of discs (5 in this embodiment) mounted as individual units to the frame 11. Each disc gang 14 includes a gang frame collectively designated 16 which, in this embodiment, inclu-des a main beam 17 with an auxiliary beam 18 therebehind.
Hangers 19 depend from the main beam 17 and support an axle 20, for rotation therein, suitable bearings (not illustrated) ; being provided for rotation of the axle 20 and individual discs 21 are secured to this axle as shown in Figure 1 and in a conventional manner~
Means are provided to hingedly secure each disc gang : independently to a member llA of the frame of the implement ;~ and in this connection, hinge sleeves 22 are secured as by welding, to the rear side of the frame member llA in spaced ~: apart relationship. A further hinge sleeve 23 is secured as by welding to adjacent the rear of the upper surface of the main beam 17 of the disc gang and a hinge pin 24 extends through the hinge sleeves 22 and through the hinge sleeve 23 .. ,. , . : .
. , , ,- ' ~ ,, ~ -, .
-" '' ' - ~ :
thus pivotally securing the disc gang in position. These pins are preferably detachable so that the entire disc gang can be removed for repair or replacement, if necessary.
Reference to Figure 3 will show a support member 25 which extends downwardly from the auxiliary gang frame mem-ber 18 and supports a conventional disc scraper (not illus-trated).
It will be noted from Figures 2 and 3 that the im-plement normally travels in the direction of arrow 26 and t,hat the disc gang ].4 hinges rearwardly around the hinge pin 24.
However, normally the disc gang assembly 1~ is in the position shown in Figure 2 and is detachably maintained in this position by means of a trip assembly collectively designated 27 which is operatively connected between the frame 10 of the implement and the gang frame 16.
~: This trip assembly consists of supporting structure collectively designated 28 which includes a plate 29 bolted to a bracket 30 welded to the upper side of the frame member llA. A pair of side flanges 31 extend forwardly from the plate 29 and a spring support arm 32 is secured as by weld-ing or the like between the plates 31 and extends upwardly and rearwardly therefrom, the purpose of which will be here-inafter described.

~ s,~7~
A bell crank component 33 is pivoted between lugs 34 towards the front of the side plates 31, by one end of the bell crank component and a wishbone type link 35 is pivotally secured adjacent the other end of -the bell crank component, by means of pivot pin 36. This wishbone type link 35 is shown in front elevation in Figure 6 and com-prises the main arm 37 which diverges outwardly to the two portions 38, one upon each side of a pivot member collec-tively designated 39 to which the wishbone type link 37 is l~ pivotally secured by means of pivot pin 40.
This pivot member is in turn pivotally secured bet-ween the plates 31 by means of a pivot pin 41 and normally extends outwardly from the ends of the side plates 31.
Further link means 42 are pivotally connected by one end thereof to the other end of the pivot member 39 by means of pivot pin 43 and this ~urther link means 42 is in turn pivotally secured between lugs 44 depending downwardly from the front edge of the main beam 17 of the disc gang frame 16, pivot pin 45 providing this connection.
Referring back to the spring anchor member 32, a pair of tension springs 46 are secured by one end thereof, one upon each side of the bell crank component 33 by means of the ends of the spring engaging over headed pins 47 extend-ing one from each side of the bell crank component. The other ~ ,...
ends of the springs 46 are secured to the inner ends of adjusting rods 48 which engage through apertures in a cross member 49 at the upper end of the spring anchor mem-ber 32. Nuts 50 screw threadably engage the screw threaded portion of the portion 48 and are situated one upon each side of the cross member 49 thus allowing limited adjustment of the tension of the springs 46.
~n operation, the tension of the springs normally maintains the disc gang in the ground working position il-lustrated in Figure 2 with the main beam of the gang frame 14 being against the underside of the frame member llA of the implement and the tension ol the springs 46 together with the leverage characteristics of the linkage assembly is sufficient to maintain the disc gangs in this position under normal working conditions.
However, if one or more of the individual discs 21 of any of the disc gangs 14 strikes an obstruction within the ground such as a rock or a heavy root or the like, then the disc gang pivots rearwardly as shown in Flgure 3, thus extending the springs 46 and when fully tripped, as shown in Figure 3, the various components of the linkage take up a position substantially as illustrated ln Figure 3. As soon as the obstruction is passed, then the springs 46 exert sufficient pressure to return the disc gang to the original - -.. :
, , , - .:
7~
ground working position shown in Flgure 2. This means that only a few discs are displaced at any one time and that the implement itself is not raised clear of the ground as in conventional disc type implements.
Finally, it should be noted that the pivotal con-nection between the further link 42 and the pivot member 39 identified by reference character 43, preferably takes the form of a nut and bolt assembly so that if it is necessary or desirable to remove any one of the disc gang assemblies, it is only necessary to remove this bolt type pivot 43 and remove the hinge pin 24 whereupon the entire disc gang can be removed from the implement and either repaired or repla-ced by a spare disc gang component.
Since various modifications can be made in my inven-tion as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departins from such spirit and scope, it is intended that all matter contained in the accom-panying specification shall be interpreted as illustrative 2~ only and not in a limiting sense.
