Abstract
TRANSPORT ATTACHMENT FOR PACKER DRILLS AND THE LIKE
ABSTRACT OF THE DISCLOSURE
Packer drills and the like are usually loaded onto a two-wheeled dolly or the like for transportation purposes and then pulled by a tractor. This is because such devices normally do not include rear wheels, but ride on the packer wheels or elements. This is, of course, awkward for trans-portation particularly when relatively wide articulated packer drill assemblies have to be moved. With the present device, a rear castor wheel assembly is secured to each side of the rear end of each section and fluid operators raise and lower these ground engaging castor wheels. When lowered for transport, a lever and cable arrangement which is opera-tively connected to the packer wheel unit, lifts the packer wheel units clear of the ground. When the castor wheel as-semblies are raised for field use, the packer wheel units are lowered to the operating position.

TRANSPORT ATTACHMENT FOR PACKER DRIILS AND THE LIKE
BACKGROUND OF T~E INVENTION
This invention relates to new and useful improve-ments in attachments for packer drill units or assemblies.
Such devices normally lnclude a pair of front ground engaging wheels, furrow and seed disc openers supported from a frame, a seed box supported in the frame, and rear packer wheel as-semblies which support the rear of the assembly when it is pulled by a tractor or the like.
Such devices are difficult to transport because of the undesirability of moving the devices upon the packer wheels. Furthermore, due to the width of such implements, particularly when connected together in side by side relation-ship, they cannot be transported normally, in the field opera-ting position. The operator therefore has to mount the de-vices on a low-bed trailer or the like or, if they are not too wide, back the assemblies onto a wheeled dolly engaged by the packer wheel unit. Either method is inconvenient and awkward.

,' DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference should first be made to Figures 1 and 2 in which a standard press drill assembly is illustrated including a supporting frame collectively designated 10 having spaced and parallel longitudinally extending side frame members 11 and at least one cross member 12. A transversely extending seed box 13 is mounted upon the supporting frame and extends over the side members 11.
Front ground engaging wheel assemblies 14 are secu-red to the front ends of the frame members 11 and include ver~
tical frame members 15 and ground engaging tired wheels 16 journalled for rotation in the lower ends thereof. These wheels are usually castoring action type wheels.
7~'7~7 Furrow opening and seed disc assemblies 17 are pivotally secured across the supporting framework and are - adjustable in position for depth control, by r.leans of an hydraulic or fluid operator 13 connected to a source of hydraulic power (not illustrated) and usually carried by the towing means such as a tractor (also not illustrated).
Conventional linkage 19 extends between the fluid operator or ram assembly 19 and the seed disc and furrow opening assemblies 17.
Situated behind the seed disc and furrow opening assemblies 17, is a plurality of packer wheel units 20 jour-nalled for rotation within depending support members 21 se-cured by the upper ends thereof to the supporting frame 10, all of which is conventional. Means may be provided to apply pressure to the packers but normally the weight thereof is sufficient and in this connection, they are normally hinged to the frame as indicated by pivot 22, so that they may be relatively free floating and follow the surface contour.
The invention collectively designated 23 is situa-ted rearwardly of the press drill assembly and in this embo-diment, includes a pair of rear ground engaging wheel assem~
blies collectively designated 2~, there being one of such as semblies for each of the longitudinal frame members 11.
~7~7 Although only a single standard press drill assem-bly is shown in the drawings, nevertheless it will be appre-ciated that such assemblies can be connected together in side by side articulated relationship and pulled from a single tractor. However, as such connections are conventional, it is not believed necessary to show same. Suffice -to say that each section is provided with at least one rear ground enga-ging wheel assembly and preferably -two such assemblies, one at each end of eachpress drill section Each rear ground engaging wheel assembly includes a frame portion 25 pivotally secured to the rear end of the side frame member 11 by means of pivot 26 so that it may move in a vertical plane as will hereinafter be described.
Figures 4 through 7 show various methods of attach~
ing this frame portion 25 to the side frame member 11. In Figure 4, a butt plate 27 is welded to the rear end of the frame 11 and a corresponding butt plate 28 is welded to the frame portion 25. The two butt plates 27 and 28 are welded together and the hinge 26 consists of a pair of spaced and parallel portions 29 formed on the distal end of the inner portion 25A of the frame portion 25 with a single extending lug 30 being formed on the rear end of the frame portion 25B.
Pivot pin 26 extends through these portions as clearly shown in Figure 1 thus pivoting the portion 25B for movement in a vertical plane relative to the portion 25A.
~7~
Figure 5 shows a similar configuration to that illustrated in Figure 4 with the exception that the plates 27 and 28 are secured together by fasteners such as nut and bolt assemblies 31.
In Figure 6, the portion 25A is bolted transver-sely to the rear end of the frame member 11 by means of nut and bolt assemblies 32 and in Figure 7, the portion 25~ is strapped to the rear end of the frame member 11 by means of encircling strap components 33 which in turn are secured by nut and bolt assemblies 34.
In all cases, a castor wheel assembly collectively designated 35 is mounted on the rear end of the frame portion 25, said assembly including a vertical attaching portion 36 which is mounted for pivotal action in a horizontal plane in a conventional manner. This portion 36 terminates in a wheel fork 37 between which a ground engaging wheel 38 is ~ournal-led for rotation.
A pair of ].ock plates 39 and 40 are provided, 39 being stationary and secured to the underside of the frame ~0 portion 25 and plate 40 being secured to the member 36 and rotatable therewith. A pin 41 may be selectively engaged within matching apertures 42 within the plates to prevent rotation but, when removed, the wheel assembly is fully castoring in its action.
~7~
Means are provided to raise and lower the rear ground engaging wheel assembly around the pivot 26, said means taking the form of a fluid operator or ram assembly collective-ly designated 43 and being pivotally mounted by one end thereof to a lug 44 secured to and extending upwardly from the frame member 11.
The piston rod 45 is pivotally secured to a further lug 45 secured to and extending upwardly from the frame portion 25 forwardly of the pivot 26. The fluid operator or ram is operatively connected to the hydraulic system of the towing vehicle (not illustrated) and operates in the usual way. When the ram assembly is contracted, then the wheel assembly is lift-ed clear of the ground pivoting around pivot point 26 and when it is lowered, the wheel assembly engages the ground.
Means are provided to lift the packer units clear of the ground when the wheel assembly is lowered and to lower the packer units into contact with the ground when the wheel assem-blies are raised. Said means take the form of a link 46 secured by one end thereof to the underside of the frame portion 25 rear wardly of the pivot 26 as clearly shown. It passes through a lock pin bracket or clevis 47 secured to and depending downwardly from the underside of the frame member 11 and is normally secur~
ed in this position by means of a lock pin 43 extending throuyh the clevis or bracket 47 and through the link 46 intermediate the ends thereof. Means such as a flexible cable 49 is secured by one end thereof to the distal or forward end of the link 46 and by the other end thereof to the packer unit by means of a clamp 50 or the like secured to the members 21 supporting the packer unit.
In the position shown in Figure 2, the rear ground engaging wheel assemblies are in the lowermost or ground en-gaging position due to the extension of ram 43 thus lifting the packer unit 20, clear of the ground. They are maintained in this position by means of a lock pin 48 as hereinbefore described.
Under these conditions, the press drill assembly can be pulled lengthwise by means of a tractor or the like being engaged with a tow bar assembly Sl secured to one end of the supporting frame of the press drill. The lock pin 41 is also removed so that the wheel assemblies are fully cas-toring thus enabling the press drill to be -transported from one place to another.
When it is desired to use the press drill in field position, the lock pins 48 are removed and the ram 43 retxac-ted thus lifting the rear ground engaging wheel assemblies to the position shown in Figure 3 at which time the rear ground 7~
:`
engaging castor wheel assemblies can be locked into position by means of lock pins 41. This lowers the distal end of the link 46 thereby allowing the packer wheel unit to be lowered : to the ground whereupon the press drill may be operated by a tractor or the like connected to the conventional hitch as-sembly 52 secured to the front tra.nsverse member 12.
Finally, it should be appreciated that a transverse rod or member 53 is secured between the frame portions 25 thus stabiliæing same and ensuring that they are raised and lowered concurrently by the respective hydraulic ram 43. This cross member 53 also prevents the rear ground engaging wheel assem-blies from placing strain on the side frame members 11 when being transported.
Since various modifications can be made in my inven-tion as hereinabove described, and many apparently widely dif-ferent embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying speci-fication shall be interpreted as illustrative only and not in a limiting sense.
The present invention overcomes these disadvantages by providing rear wheel assemblies which can be lowered into ground engaging relationship and which at the same time, can 7~
.
lift the packer unit clear of the ground. The rear wheel as-semblies are preferably castoring action type assemblies so that the press drill or seeder can be pulled lengthwise by means of a tractor or the like.
