2 Claims.
fulimprovements in listers of the two row type and has for its primary object to provide, in a :manner as hereinafter set forth, an apparatus {45 of this character which is adapted to be mounted for operation on a conventional tractor.
.Another very important object of the invention is toprovidea lister of the aforementioned characterwhich may be conveniently adjusted as desired to meet various conditions.
Other ,objects of the invention are to provide a lister of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specigo fication, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a view in side elevation of an em- 5 bodiment of the invention, showing the device mounted on a tractor.
Figure 2 is a top plan view thereof.
Figure 3 is a perspective view of the subsoiler guides.
Figure 4 is an elevational view of one of the guides, showing the subsoiler beam in cross section.
Referring now to the drawings in detail, it will be seen that the reference numeral I designates generally a portion of a conventional tractor. The embodiment of the present invention which has been illustrated comprises a pair of bars 2 which are pivotally connected at their forward ends, as at 3, to the tractor I at an intermediate point. The bars 2 extend rearwardly and downwardly from their pivotal connections 3 and pivotally connected, as at 4, to the rear ends thereof is a pair of beams 5.' Subsoilers 6 are mounted on the free, rear end portions of the beams 5.
Mounted horizontally on the rear end portion of the tractor I is a base I in the form of a plate. Journalled in suitable bearings 8 which are provided therefor on the base I is a pair of spaced,
parallel, transverse shafts 9 and I0. Forwardly extending arms II are fixed on the end portions of the shaft I0. Pivotally connected to the free end portions of the arms II and depending therefrom are links I2. The lower end portions 56 of the links I2 are adjustably connected to the V The present invention relates to new and userear end portions of the bars 2 for raising and lowering said bars, as at I3 (see Fig. 1).
Mounted for swinging movement in a vertical plane on the base I is a hand lever I4. A link I5 'operatively connects the hand lever I4 to an 5 arm I6 which is fixed on the shaft Ill at an intermediate point. Thus, the bars 2, with the beams 5, are connected to the hand lever I4 in a manner to be raised or lowered thereby. Extending between the usual gear casings I! of the rear end of the tractor I is a horizontal bar I8. Depending from the end portions of the bar I8 is a pair of substantially U-shaped guides I9 in which the forward end portions of the beams 5 travel.
Fixed on the end portions of the shaft 9 is a pair of rearwardly extending arms 20. The rear end portions of the beams 5 are suspended from V the arms 20 through the medium of chains 2|. Also fixed on the shaft 9 is an upwardly extending arm 22. A cable 23 connects the arm 22 to the usual power drum 24 of the tractor I. Thus, a power lift is provided for the subsoilers 6.
It is thought that the manner in which the implement functions will be readily apparent from a consideration of the foregoing. Through the medium of the hand lever I4, the bars 2 may be conveniently raised and lowered as desired from the operator's seat of the tractor. As hereinbefore mentioned, the connections I3 permit different adjustments that may be desired to be made between the bars 2 and the respective links I2. The substantially U-shaped guides I9 prevent lateral play of the bars 2, the subsoiler beams 5, etc. It will be observed that the chains 2| fioatingly support the rear ends of the vertically swinging beams 5 with the subsoilers 6 thereon. Through the medium of the cable 23 which is connected to the power drum or unit 24 of the tractor I, the elements 20, 2|, 22, etc., the subsoilers may be conveniently elevated when desired. The construction and arrangement is such that the subsoilers may be caused to operate uniformly at any desired depth. The seed boxes (not shown) may be mounted either on the lister or directly on the tractor and driven in any suitable manner from the latter. As shown to advantage in Fig. 2 of the drawings, a bar 25 extends transversely between the rear portions of the beam 5.
It is believed that the many advantages of a lister constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the apparatus is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is:
I. A tractor lister comprising a pair of bars pivotally connected at one end to an intermediate portion of the tractor and extending downwardly and rearwardly therefrom, a bar mounted transversely on the rear end portion of the tractor, a pair of substantially U-shaped guides depending from the transverse bar, a pair of beams pivotally connected to the other ends of the first named bars and operable in the guides, subsoilers mounted on said beams, a base mounted on the rear end portion of the tractor, a transverse shaft journalled on said base, a pair of arms fixed on the end portions of said shaft, links pivotally connected to the free end portions of said arms and depending therefrom and adjustably connected to the free end portions of the first named bars, a hand lever pivotally mounted on the base, another arm fixed on the shaft, a link operatively connecting the second named arm to the "lever for operatively connecting the first named bars to said lever for raising and lowering thereby, and means operatively connecting the beams to the power drum of the tractor for lifting the subsoilers.
2. A tractor lister comprising a pair of bars pivotally connected at one end to an intermediate portion of the tractor and extending downwardly and rearwardly therefrom, a bar mounted transversely on the rear end portion of the tractor, a pair of substantially U-shaped guides depending from the transverse bar, a pair of beams pivotally connected to the other ends .of the first named bars and operable in the guides, subsoilers mounted on said beams, a base mounted on the rear end portion of the tractor, a transverse shaft journalled on said base, a pair of arms fixed on the end portions of said shaft, links pivotally connected to the free end portions of said arms and depending therefrom and adjustably connected to the free end portions of the first named bars, a hand lever pivotally mounted on the base, another arm fixed on the shaft, a link operatively connecting the second named arm to the lever for operatively connecting the first named bars to said lever for raising and lowering thereby, and :means operatively connecting the beams to the power drum of the tractor for lifting thesubsoilers, said means including another shaft journalled transversely on the base, a pair of .arms fixed on the end portions of the second named shaft, flexible elements suspending the beams from the last named arms, and a cable-operatively connecting the second named shaft to the power drum of the tractor for actuation thereby.
