Abstract
ABSTRACT OF THE DISCLOSURE
A tiltable frame is mounted on wheels and connects to a tractor or truck by means of a hitch pole assembly pi-voted to the frame just rearwardly of the front end of the frame. A pair of substantially semi-cylindrical troughs are situated on the frame one adjacent each longitudinal side thereof, to receive round bales lengthwise thereon. A pick-up is pivoted to one side of the frame near the front end and is movable from a bale pick-up position to a bale transfer position by means of a fluid operator. As the pick-up moves with a bale through approximately 90° to the transfer posi-tion, the bale rolls from the pick-up to one of the troughs. If there is no bale on the far side trough adjacent the pick-up, the bale rolls across the first trough to the second trough and is restricted from further movement by a restraining bar on the side of the frame adjacent the second trough. When two bales are positioned side by side, one in each trough, trans-versely of the pick-up, a push bar assembly moves them rear-wardly along the troughs, a distance sufficient to permit loading two more bales. When unloading, the frame tilts rear-wardly and the push bar pushes the bales rearwardly from the rear end of the troughs. The tractor or truck can be in neu-tral so that it is moved forwardly as the bales are ejected from troughs onto the ground. The tilting of the frame faci-litates the sliding movement of the bales during the unloading action and prevents them from tipping upwardly onto the ends as they strike the ground.

Description
~3';~
~ ~, BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in bale carriers, particularly bale carriers desiyned for use with relatively heavy cylindrical bales now becoming extremely popular.
These cylindrical bales may weigh between 800 and 1,000 pounds or more and consequently are difficult to pick up and move from one place to another.
:
Many attempts have been made ~o design equipment for this purpose, the majority of which eithex load from the front requiring a swing hitch assembly or require a separate pick-up device such as a fork lif~ or front end loader.
Once the bales have been moved to the desired loca-tion, they then have to be removed from the truck or carrier and often they are just dumped so that the blow upon the ground often breaks the strings and causes the bales to become loose.
Alternatively, the bales tend to tip up on end which is unsa-tis~actory for stoxage purposes.
~:
' SUMMARY OF THE I;NVENTION
~0 The present invention overcomes these disadvantages by providing a bale carrier which can be pulled by truck or tractor and which incorporates a side loading device which will engage the bale, enable same to be elevated onto the car-. .
rier and then when it is desired to dump the bale, means are .......... ..
.
~ ~, - . - - . ~ . , . .. : . '' . :
:~V~:~2~
provided to tilt the main frame so that the bale can be ejected upon the ground without the bale dropping a considerable dis-tance and without the bale turning up on end.
In accordance with the invention, there is provided a bale carrier for cylindrical bales of hay and the like to-gether with an associated source of hydraulic fluid under pres-sure; comprising in combination a main frame, ground engaging wheels, means mounting said frame upon said wheels, a hitch pole assembly secured by the rear thereof to said frame adja-cent the front thereof, a cylindrical bale pick-up assembly mounted on one side of said frame, means to move said pick-up assembly from a substantially horizontal bale pick-up position to a substantially vertical bale transfer position and vice-versa, a pair of spaced and parallel cylindrical bale receiv-ing platforms situated longitudinally on said main frame, saidbales rolling from said pick-up assembly by gravity, to said bale receiving platforms when said pick-up assembly moves from said bale pick-up position towards said bale transfer position, and means mounted on said main frame to move the cylindrical bales longitudinally along said platforms.
Another advantage of the present device is that a pair of platforms may be provided in side by side relationship together with means to move the bales rearwardly once they have been loaded upon the càrrier thus making room for additional bales to be placed on the carrier.
-Still another advantage of the present device is that ~ ,; . , _3_ the frame may be made tiltable so that, when unloading, therear end of the ~rame is positioned close to the ground. This facilitates the unloading action as the weight of the bales tends to assist the push bar assembly in the movement of the bales along the carrier. Furthermore, they are not dropped upon the ground and the angle of the position is such that they do not tip up onto an end as they leave the carrier.
With the fore,going in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, our invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

A pick-up assembly is provided collèctively designa-; ~ ted 27 and is situated on one side of the main frame adjacent the front end 17 therPof. It includes a pair of angulated arms 28 and a cross bar 29 with the distal ends of the arms 28 beinq :~ .
pivotally connected between lugs 30 by means of pivot pins 31, ~0 situated on the said side of the main frame 10. A first pick-up arm 32 extends forwardly from the other ends of the angula-ted axms 28 and a seeond pick-up arm 32A extends substantially parallel to the first arm 32, but is mounted on a transversely extending member 33 extending from the rearmost angulated arm 28.

32A can be varied to suit the diameter o~ the bale being picked up thereby.
The forward ends 35 of these arms 32 and 32A curve outwardly to facilitate the engage:ment upon each side of the bale 36 when same is being picked up, it being understood that these arms enga~e the bale longitudinally one upon each side thereof and below the transverse axis thereof as illustrated in Figure lA.
A fluid operator 37 (see Figure 6) is pivotally secured by one end thereof to the side of the main frame 10 between the angulated arms 28 and extendsto be pivotally con-nected to a lug 38 depending from cross member 29 or a bracket extending therefrom. By connecting this fluid operator to a source of hydraulic fluid under pressure supplied by the truck or tractor! the fluid operator may be extended or retracted, thereby moving the pick-up assembly 27 from a substantially horizontal bale pick-up position illustrated in Figures 1 and
2, to a substantially vertical bale transfer position shown in Figure 7.
, . -A curved sheet or pan 39 extends from the pick-up arm 32 and curves upwardly to be supported in a substantially spaced and paral]Lel position to the inner portions of arms 2B, , by means of brac}cets 40, the purpose of which will be herein- -.after described.

InsoEar as the pick-up operation is concerned, the pick~up assembly 27 is lowered to the bale pick up position illustrated in Figure l with the forward ends 35 of the pick-up arms or bars 32 and 32A being situated just above the ground.
The truck or tractor to which the carrier is secu-red, is driven forwardly so that the arms engage each side of the bale longitudinally as shown in Figure lA. The fluid operator 37 may now be actuated thus elevating the pick-up assembly together with the bale towards the position shown in Figure 7 whereupon the bale will roll sideways towards the car-rier being supported and guided by the curved plate 39.
When two platforms ~5 are provided, the bale will roll onto the platform adjacent the pick-up assembly 27 with sufficient momentum to roll across the space between the two platforms, and onto the platform remote from the pick-up as-sembly 270 In this connection, longitudinal bars 40 are sup-ported upon transverse~bars 41 across the front of the space between the two platforms 25.
2ID Ueans are provided to check the moti.on of the bale as it rolls onto the second platform, said means taking the :
form of a bale restraine.r collectively designated 42~ This :. .
comprises a pair~of brackets 43 secured to and extending dia gonally upwardly from the side of the carrier opposite tv the .
side to which the pick-up assembly 27 is attached~ These brackets support a check bar 44 in spaced and parallel rela- ..
tionship spaced from and above the far side edge 45 of the - .
.
g _ . .
: , iv~
carrier lO so that the side of the bale rolls against this and checks the movement so that it rests within the front portion of the trough of the left-hand platform with respect to Figure l.
When a further bale is then picked up by the pick-up assembly 27, and the pick-up assembly is elevated to the bale transfer position, this second bale rolls onto the first ~ .
platform and cannot.go any further being restrained by the bulk of the first bale already in position.
At this point, a pair of bales are situated on the front of the two platforms 25 and before further bales can be placed upon the carrier, these two bales have to be moved rear-wardly along the platforms 25.
Means are therefore provided to mov~ the bales rear-wardly taking the form of a pusher bar assembly collectively designated 46. In this embodiment, it comprises a length of angle iron or the like 47 situated transversely across the car-rier and having a pair of upwardly extending bale end engaging plate 48 secured to the vertical flange 49 of the angle iron : 20 and extending upwardly therefrom being braeed by forw~rdly posi-. tioned gussets 50 as clearly illustrated.
This pusher bar rests upon the carrier and spans `
both the platforms 25 and the portion therebetween.
. .
, '73Z~
A pair of link chains 51 are mounted upon rear chain sheaves 52 journalled upon a transverse axle 53 extend-ing across the carrier frame adjacent the rear end thereof.
These two chains also engage around front chain sheaves 54 secured to a drive shaft 55 journalled for rota-tion within the front end of the c:arrier 10.
One end of the upper runs 51A of the two chains are secured to the rear side of the pusher bar assembly 46 in the portion thereof extending across the area between the two platforms.
The other ends of the chains are secured to the front side of the pusher bar assembly and a conventional chain tightening adjuster 56 is provided at these locations so that the tension within the chain can be adjusted within limits.
.
Means are provided to drive the two chains 51, taking the form, in this embodiment, of an orbital motor 57 supported within a boxing 58 secured to and extending forwardly from the front end 17 of the carrier with flexible hydraulic hoses 59 being provlded and operatively connected to the source of hydraulic 1uid under pressure within the associated truck or tractor (not illustrated).
' ' . ' .
The shaft 60 of the orbital motor includes the ; ''"'' ~ ' ' :. :
.
sprocket 61 around which a drive chain 62 extends. This chain also extends around a further sprocket 63 secured to the aforementioned shaft 55 upon which the front chain sheaves 54 are secured so that rotation of the orbital motor 57 in either direction will move the upper runs 51A in either direc-tion taking with it the pusher bar assembly 46 which is atta-ched to the ends of the upper runs.
Therefore, after the first two bales are loaded, the orbital motor is operated to move the pusher bar rearward-ly thus engaging the front ends of the two bales and pushingthem along the platforms 25 until they are clear of the pick-up assembly whereupon the pusher bar assembly is returned to the front end of the carrier and two more bales are positioned upon the platforms 25.
The four kales are then moved rearwardly and the operation is repeated until sufficient bales have been placed on the carrier. In this particular embodiment illustrated, the design is such that four bales upon each side or a total of eight bales can be carried by the carrier, but of course it will be appreciated that this number of bales is not to be considered limiting.
Once the bales have been picked up, the pick-up ~
assembly 27 is elevated and the carrier is pulled by the truck -or tractor, from the field, to the area at which it is desired to unload the bales.
: ' -`~ z~
The aforementioned fluid operator 20 is then a~-tuated, raising the carrier -to the position shown in Figure 5 whereupon the orbital motor 27 is actuated moving the push bar assembly 46 rearwardly thus commencing the ejection of the bales from the platforms 25.
This ejection is facili.tated due to the angle of the carrier so that the weight of the bales assist in the sliding action thereof along the platforms 25. If the truck or trac-tor is placed in neutral or, alternatively, driven forward slowly, then the bales will eject from the end of the carrier upon the ground without falling any distance and obviating any tendency of the bales to tip upwardly on end which is undesi-rable.
When the bales have been unloaded, the carrier is returned to the substantially horizontal position ready for picking up further bales.
Since various modifications can be made in our in~
vention as hereinabove described, and many apparently widely .:
different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scop~, it is intended that all matter contained in the accompanying spe-: cification shall be interpreted as illustrative only and not in a limiting sense.

The truck or tractor to which the carrier is secu-red, is driven forwardly so that the arms engage each side of the bale longitudinally as shown in Figure lA. The fluid operator 37 may now be actuated thus elevating the pick-up assembly together with the bale towards the position shown in Figure 7 whereupon the bale will roll sideways towards the car-rier being supported and guided by the curved plate 39.
When two platforms ~5 are provided, the bale will roll onto the platform adjacent the pick-up assembly 27 with sufficient momentum to roll across the space between the two platforms, and onto the platform remote from the pick-up as-sembly 270 In this connection, longitudinal bars 40 are sup-ported upon transverse~bars 41 across the front of the space between the two platforms 25.

The other ends of the chains are secured to the front side of the pusher bar assembly and a conventional chain tightening adjuster 56 is provided at these locations so that the tension within the chain can be adjusted within limits.
.
Means are provided to drive the two chains 51, taking the form, in this embodiment, of an orbital motor 57 supported within a boxing 58 secured to and extending forwardly from the front end 17 of the carrier with flexible hydraulic hoses 59 being provlded and operatively connected to the source of hydraulic 1uid under pressure within the associated truck or tractor (not illustrated).
' ' . ' .
The shaft 60 of the orbital motor includes the ; ''"'' ~ ' ' :. :
.
sprocket 61 around which a drive chain 62 extends. This chain also extends around a further sprocket 63 secured to the aforementioned shaft 55 upon which the front chain sheaves 54 are secured so that rotation of the orbital motor 57 in either direction will move the upper runs 51A in either direc-tion taking with it the pusher bar assembly 46 which is atta-ched to the ends of the upper runs.
Therefore, after the first two bales are loaded, the orbital motor is operated to move the pusher bar rearward-ly thus engaging the front ends of the two bales and pushingthem along the platforms 25 until they are clear of the pick-up assembly whereupon the pusher bar assembly is returned to the front end of the carrier and two more bales are positioned upon the platforms 25.
The four kales are then moved rearwardly and the operation is repeated until sufficient bales have been placed on the carrier. In this particular embodiment illustrated, the design is such that four bales upon each side or a total of eight bales can be carried by the carrier, but of course it will be appreciated that this number of bales is not to be considered limiting.
Once the bales have been picked up, the pick-up ~
assembly 27 is elevated and the carrier is pulled by the truck -or tractor, from the field, to the area at which it is desired to unload the bales.
: ' -`~ z~
The aforementioned fluid operator 20 is then a~-tuated, raising the carrier -to the position shown in Figure 5 whereupon the orbital motor 27 is actuated moving the push bar assembly 46 rearwardly thus commencing the ejection of the bales from the platforms 25.
This ejection is facili.tated due to the angle of the carrier so that the weight of the bales assist in the sliding action thereof along the platforms 25. If the truck or trac-tor is placed in neutral or, alternatively, driven forward slowly, then the bales will eject from the end of the carrier upon the ground without falling any distance and obviating any tendency of the bales to tip upwardly on end which is undesi-rable.
When the bales have been unloaded, the carrier is returned to the substantially horizontal position ready for picking up further bales.
Since various modifications can be made in our in~
vention as hereinabove described, and many apparently widely .:
different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scop~, it is intended that all matter contained in the accompanying spe-: cification shall be interpreted as illustrative only and not in a limiting sense.
