Description
` ~2423S2 BALING MACHINE
BACKGROUND OF TOE I~V~TION
This invention relates to a baling machine and particularly one of the type comprising a cylindrical chamber or housing into which harvested material is fed and is rolled by belts within the housing into a large cylindrical bale.
Baling machines of this type have become very popular for various reasons in recent years and are widely used for baling harvested material from swaths.
The operation is now well developed and the baling tech-nique is very effective however a problem remains in relationship to the unloading of formed bales and the material which i5 fed during the unloading process.
The instruction manual or most baling machines of this type requires that prior to ejection of a formed bale, the baler be halted in its movement across the ground and the tractor reversed so as to back up the baler by about ten (10) feet. At this stage the housing is opened by pivotal movement of a rear section of the housing about a horizontal axis at the top of the housing I, .
so as to open at an opening provided at the bottom rear i portion of the housing to allow the bale to escape. The ~2~`23S~
front and rear portions thus operate somewhat in the form of a clamshell arrangement with the bale being ejected from the opened housing by the belts which form the bale within the housing.
With the bale ejected from the housing, the tractor can move forward so that the rear portion clears the bale and then can close the housing to restart forma-tion of the next bale. During the forward movement, because of the previous backup, no material is fed into the baler for those ten (10) feet so that by the time the baler encounters fresh material for collection it is closed and ready to continue operation.
This operation is however unsatisfactory in that the operator has to stop and maneouver the tractor and baler which iB undesirab.Le and therefore the operator attempts to avoid it. q'his can cause a number of prob-lems including contacting the bale with the rear portion as it closes, feeding material right through the front portion of the baler and out the opening which can waste material and fu:rthermore material can be trapped between the two portions of the housing as they close and thus can inhibit the proper formation of a bale within the housing and can cause jamming of the feed mechanism into the housing.

Proposals have been made in U.S. Patent No.
3,914,922 (Todd) and in U.S. Patent No. 4,135,352 (Swen-son) both of which propose spring-mounted tines which are normally biased into position which inhibits movement of material from toe feed mechanism into the housing The spring tines are then depressed by the formation of the bale to a position where the formation can continue.
Both of these arrangements are concerned with the type of baler including an elongate inner belt run which extends substantially wholly around the interior surface of the housing and expands as the bale increases in size. Following ejection of the bale the elongate band i5 drawn inwardly relative to the inner surface of the chamber or housing. In addition both of the above devices are unsatisfactory in that they can interfere with the proper formation of the bale particularly in the type of device wherein the belts lie around the periphery of the housing and are formed by a number of separate belt runs as opposed to the continuous belt run which collapses into the interior of the housing when the bale is ejected.
It is one object of the present invention, therefore, to provide an improved bailing device which overcomes the disadvantages of the above arrangements.

According to a second aspect of the invention there is provided a baling machine comprising a sub-stantially cylindrical housing, a plurality of belt run portions arranged around an inner periphery of the hous-ing in spaced relation to one another angularly of the housing defining a chamber, means at a bottom front position of the housing for feeding crop material from a swath into the chamber for rolling by the belt portions into a bale, the housing including a front portion and a rear portion, means mounting the rear portion on the front portion for pivotal movement about a horizontal axis arranged adjacent the top of the housing so as to open at an opening at a bottom rear position of the housing to allow a formed bale to escape from the chamber, one of the belt run portions including a plural-ity of separate belts spaced axially of the housing each having an inner run extending from said feeding means to said opening, means for halting feeding of said material into said chamber, said halting means consisting solely of a plurality of tines movable from a retracted position in which they wholly underlie the inner run of the belts to a raised position in which they project between the inner runs inwardly into the housing, said tines being ,, .

The tines can therefore can be operated by opening and closing of the clamshell front and rear por-tions so that when the rear portion is closed the tines are immediately retracted to a position underlying the lower belt so that they cannot interfere with the forma-tion of the next bale.
This is particularly important in relation to the type of baler using separate belt portions which ' ~Z~2;:~i2 remain around the periphery of the housing rather Han collapsing tO the interior of the housing since the pro-jection of tines into the interior can interfere with the proper rolling of the material around the interior. Thus even if the tines can be compressed by the formation of the bale their presence during the initial portions of the bale formakion can interfere with the proper forma-tion of the bale.
With the foregoing in view, and other advan-tages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the best mode known to the applicant and of the preferred typical embodiment of the principles of the present invention, in which:

DETAILED DESCRIPTION
Referring firstly to figure 1 there is shown a baling machine of a conventional type which includes a housing 10 mounted on groundwheels 11 and drawn by a hitch 12 from a tractor (not shown).
The housing is formed in two portions compris-ing a front portion 13 and a rear portion l which are relatively hinged at a horizontal axis 15 so that they can open at an opening point 16 to assume the position illustrated in Figure 2 in which the chamber is opened to allow the exit of a formed bale.
A feed mechanism indicated schematically at 17 is provided at a front lower portion of the housing 10 for collecting harvested material in a swath 18.
Within the housing a bale is formed by a plur-ality of belts which are arranged around the periphery of the cylindrical housing 10. A first belt indicated at 19 is formed at the bottom of the housing extending from the inlet of the feed section 17 to the opening 16 for initi-~Z4Z3~Z
ally conveying the -Eed material across the bottom of the housing. The belt l9 is mounted on dry rollers 20 and a tensioning roller 21 extending parallel to toe axis of the cylindrical housing lO with one or more of the rol-lers 20 driven in a direction to move the upper or inner run of the belt l9 indicated at 22 in a rearward direc-tion toward the opening 16.
Rearwardly of the roller 20 at the opening 16 is provided a further belt 23 mounted on rollers 2~ and carried by the rear portion 14 of the housing. This belt also provides an inner run which carries the material from the rear end of the belt 22 rearwardly and upwardly in the housing toward a further belt 25 mounted on rol-lers 26 and from there to a yet further belt 27 mounted on rollers 28. From the end of the belt 27 extends first belt 29 and a second belt 30 in the front portion 13 of the housing the latter extend downwardly to the front of thè belt 22. Thus the inner runs of each of the belts comblne to form a rotating supporting surface for the material around the inner periphery of the housing lO
with each of the belt forming a portion of the periphery spaced angularly of the housing. It will be appreciated that the pivot axis 15 and the opening 16 are provided between adjacent ends of respective belts so that the .
.~ .
~24~35;;~
opening causes movement of the belt 23 away from the belt 22 to allow the escape of a formed bale.
As illustrated in Figure 3, each cf the belts 22, 23, 2~, 27, 29, 30 is formed of a plurality of separ-ate bands 31 which are spaced axially of the housing and which co-operate to effectively form an apron or belt extending the full width of the chamberO The rollers 20, 24, 26, 28 are fixed to the respective housing portion and hence retain the belts a the outer periphery of the housing regardless of the amount of material within the housing.
As shown in Figure 3 a plurality of tines 30 are provided each of which passes through a respective slot between two of the bands 31. The tines 30 are arcuately curved so as to present a concave side to the upstream side of the belt run 22 in the raised position illustrated in Figures 2 and 3. The tines are mounted upon an elongate actuating rod 33 which extends across the bands 31 to one side for connection to a lever 34 which is positioned outside the housing on one sidewall.
The lever 34 is connected to a push-rod 35 which extends downwardly along the outer surface of the sidewall which in turn is pivotally connected to a bell-crank 36 includ-ing a first leg at 37 and a second leg at 38 at right ,., ~2352 angles to the first. The bell~crank is also connected by an extension portion 39 to a spring 40 which provides spring-bias in a direction to lift the tines 32 into the raised position illustrated in Figures 2 and 3. The end of the portion 38 of the bell-crank 36 is attached to a curved slide rod 41 which passes through a guide 42 at-tached to the front portion of the housing on an outer surface of the end face thereof. The slide rod 41 in-cludes an end abutment face 43 for engaging a fixed stop 44 attached to the outer face of the rear portion 14 of the housing.
In operation with the rear portion 14 of the housing closed, the stop 44 engages the slide rod 41 which in turn rotates the connecting rod 33 via the bell-crank 36 in an anti-clockwise direction as shown in Figure l to retract the tines 32 to a position where they are fully underlying the upper run 22 of the belt l9. In this position the tines 32 in no way interfere with the rolling or tumbling of the collected harvested material and thus allow it to be rotated by the belts to roll into a bale which is of the generally cylindrical shape de-fined by the belts themselves.
When the formation of the bale is complete, the operator can open the rear portion 14 of the housing to ~242352 vested material around the chamber under control of the belts.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments o 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 specification shall be interpreted as illustrative only and not in a limiting sense.

DETAILED DESCRIPTION
Referring firstly to figure 1 there is shown a baling machine of a conventional type which includes a housing 10 mounted on groundwheels 11 and drawn by a hitch 12 from a tractor (not shown).
The housing is formed in two portions compris-ing a front portion 13 and a rear portion l which are relatively hinged at a horizontal axis 15 so that they can open at an opening point 16 to assume the position illustrated in Figure 2 in which the chamber is opened to allow the exit of a formed bale.
A feed mechanism indicated schematically at 17 is provided at a front lower portion of the housing 10 for collecting harvested material in a swath 18.
Within the housing a bale is formed by a plur-ality of belts which are arranged around the periphery of the cylindrical housing 10. A first belt indicated at 19 is formed at the bottom of the housing extending from the inlet of the feed section 17 to the opening 16 for initi-~Z4Z3~Z
ally conveying the -Eed material across the bottom of the housing. The belt l9 is mounted on dry rollers 20 and a tensioning roller 21 extending parallel to toe axis of the cylindrical housing lO with one or more of the rol-lers 20 driven in a direction to move the upper or inner run of the belt l9 indicated at 22 in a rearward direc-tion toward the opening 16.
Rearwardly of the roller 20 at the opening 16 is provided a further belt 23 mounted on rollers 2~ and carried by the rear portion 14 of the housing. This belt also provides an inner run which carries the material from the rear end of the belt 22 rearwardly and upwardly in the housing toward a further belt 25 mounted on rol-lers 26 and from there to a yet further belt 27 mounted on rollers 28. From the end of the belt 27 extends first belt 29 and a second belt 30 in the front portion 13 of the housing the latter extend downwardly to the front of thè belt 22. Thus the inner runs of each of the belts comblne to form a rotating supporting surface for the material around the inner periphery of the housing lO
with each of the belt forming a portion of the periphery spaced angularly of the housing. It will be appreciated that the pivot axis 15 and the opening 16 are provided between adjacent ends of respective belts so that the .
.~ .
~24~35;;~
opening causes movement of the belt 23 away from the belt 22 to allow the escape of a formed bale.
As illustrated in Figure 3, each cf the belts 22, 23, 2~, 27, 29, 30 is formed of a plurality of separ-ate bands 31 which are spaced axially of the housing and which co-operate to effectively form an apron or belt extending the full width of the chamberO The rollers 20, 24, 26, 28 are fixed to the respective housing portion and hence retain the belts a the outer periphery of the housing regardless of the amount of material within the housing.
As shown in Figure 3 a plurality of tines 30 are provided each of which passes through a respective slot between two of the bands 31. The tines 30 are arcuately curved so as to present a concave side to the upstream side of the belt run 22 in the raised position illustrated in Figures 2 and 3. The tines are mounted upon an elongate actuating rod 33 which extends across the bands 31 to one side for connection to a lever 34 which is positioned outside the housing on one sidewall.
The lever 34 is connected to a push-rod 35 which extends downwardly along the outer surface of the sidewall which in turn is pivotally connected to a bell-crank 36 includ-ing a first leg at 37 and a second leg at 38 at right ,., ~2352 angles to the first. The bell~crank is also connected by an extension portion 39 to a spring 40 which provides spring-bias in a direction to lift the tines 32 into the raised position illustrated in Figures 2 and 3. The end of the portion 38 of the bell-crank 36 is attached to a curved slide rod 41 which passes through a guide 42 at-tached to the front portion of the housing on an outer surface of the end face thereof. The slide rod 41 in-cludes an end abutment face 43 for engaging a fixed stop 44 attached to the outer face of the rear portion 14 of the housing.
In operation with the rear portion 14 of the housing closed, the stop 44 engages the slide rod 41 which in turn rotates the connecting rod 33 via the bell-crank 36 in an anti-clockwise direction as shown in Figure l to retract the tines 32 to a position where they are fully underlying the upper run 22 of the belt l9. In this position the tines 32 in no way interfere with the rolling or tumbling of the collected harvested material and thus allow it to be rotated by the belts to roll into a bale which is of the generally cylindrical shape de-fined by the belts themselves.
When the formation of the bale is complete, the operator can open the rear portion 14 of the housing to ~242352 vested material around the chamber under control of the belts.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments o 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 specification shall be interpreted as illustrative only and not in a limiting sense.
