(Cl. loll-19) l 2 The present invention relates to baling and more particularly to baling fibrous material such Fig. 5 is a view similar to Fig.»2, showing a further modified construction. As seen in Fig. 1 the baling machine has a bale as hay, straw and the like and an object of the invention is to generally improve the methods case or chamber generally designated as I0 which and apparatus for performing this work. In may be of anysuitable or well-known type in baling hay and other forage crops, weather con which is reciprocable a plunger II, the plunger ditions and other factors at times make rit vir being moved back and forth in chamber I0 by tually impossible to bale the material when it means of a pitman I2 connected with suitable has the proper moisture content. Under these or well-known mechanism not shown and form conditions there is always the temptation to 10 ing no part of the present invention. Bale cham bale the material when it is too damp. If this ber I0 in the present instance has a feed opening is done, the chances are that the bales will spoil, I3, Fig. 2, in one side thereof and toward which particularly in the center due to molding caused extends a movable apron I4 which conveys by the excess moisture and lack of access of air fibrous material in well-known manner toward to the interior of the bales. If ventilation of the 15 opening I3. Plunger II is shown blocking open interior of the bale could be provided, this excess ing I3 but periodically moves to the dotted posi moisture could be dissipated after the bale was tion shown clear of the feed opening so that formed and stored away from the weather. Thus material moving with apron I 4 toward opening the material could be successfully baled with a I3 is projected into baling chamber Ill. The higher moisture content than has heretofore 20 return stroke of plunger II compresses this ma been feasible. The material then could “cure” at terial in chamber I0 in well-known manner, least in part in the bale and it would be pos again momentarily blocking opening I3. Toward sible to successfully make hay under conditions the end of the compressing stroke, a knife I5 on of excessive humidity which might prevent the plunger II cooperates with a .cutting block or operation with known expedients. Also other 25 shear plate I6 on chamber I0 to cut oii‘ the uses for an opening in baled material might pre material caught in opening I3 by advance of sent themselves and therefore the principal object plunger II. of the invention is to provide suitable mecha Repetition of this action, as is shown in Fig. 1, nism for producing a passageway in baled mate results in a series of separate bodies of fibrous 30 material being compressed against each other rial. Further objects are to provide a simple and into a virtually continuous body of baled mate inexpensive expedient for achieving this object; rial, the separate parts or “feeds” remaining to a such an expedient which is applicable to known certain extent independent because of the cutting baling mechanisms and such an expedient w'hich action of knife I5. will require a minimum of alteration when the 35 In the baler shown, this body of baled material is separated from time to time by fingers or slot ters I1 and I8 inserted into chamber I0 at inter device is supplied as original equipment or as an attachment for balers already built. The manner in which these objects are accom ’ vals in well-known manner so as to be caught and plished is shown in the accompanying drawing baled into the compressed material.

Fig. 2 is a horizontal sectional view taken sub 50 In the present instance in order to form the above mentioned Ventilating openings, a punch stantially on the line 2-2 of Fig. 1. 22 preferably although not necessarily provided Fig. 3 is a. perspective view of a bale made with with a reduced end portion 23 is provided and the mechanism disclosed. fixed with a head portion 24 of plunger II by Fig. 4 is a view similar to Fig. 1 showing a modified application of the invention. 55 any suitable means such for example as a screw 8,418,588 28 extending through head 2l and engaged with in punch 22, a washer 2B being interposed it de 4 sired. Punch 22' is conveniently made round 'I‘he modiiication of P18. 5 is Preferably identi cal with the structure o! Fig. 2, except for the provision of a plurality of punches I8 and Il. although other shapes might -be considered as and therefore the same reference characters within the scope of the invention. Punch 21 also 5 have-been applied to the parts corresponding to Fig. 2. This arrangement is ot utility under cir ' is preferably made somewhat longer than the cumstances such that a single opening in the bale is deemed insuillcient. The above being a complete description o! thickness of a single “feed" oi ilbrous material. The punch forms an opening through each feedl as it is compressed into the bale, the openings registering with each other so as to form a con l0 typical working embodimentsbf thc invention, tinuous passageway 21 through the baled mate rial and which will be open to the atmosphere what is claimed as new and desired to be secured by Letters Patent o! the United States is: 1. In a baler, the combination of a haling shown in Fig. 8. By having punch 22 long chamber, a plunger therein. means for feeding enough to penetrate at least part way through u material to be baled into the chamber for com at either end of each individual bale as clearly a previous feed, the punch operates to insure pression by said plunger, spaced slotters adapted a complete registration of the several holes and to be inserted at intervals into the chamber for separating the resulting bales and a punch rigid a clean passageway in the resulting bale.

The invention is not considered as limited to strokes of said plunger and punch result in a use with the type of balers shown in Figs. 1 and continuous opening through each bale and which 2, but may also be used with older type balers opening remains when the bale is removed from utilizing conventional ballng blocks for separat the machine. ing the bales. Such a construction is shown in 2. In a baler, the combination of a baling Fig. 4 in which a hailing chamber 28 has a feed chamber, a plunger therein, means for feeding opening or hopper 29 through which material material to be baled into the chamber for com and division blocks as 30 are introduced into. pression by said plunger, spaced slotters adapted chamber 28. A plunger 3| is actuated by a pit to be inserted at intervals into the chamber for man .32 and has a punch 33 ñxed with a head 35 separating the resulting. bales and a plurality 34 of the plunger in a manner similar to above ‘ of punches rigidly mounted on said plunger posi mentioned plunger 22 as by a screw 35. tioned to penetrate the material being baled at To prevent interference of block 30 with> plunger/34, an opening 3B is provided in each block and which is preferably generous enough' 40 to provide for free travel of punch 33 even though block 80 may vary somewhat from its '. usual or intended position. The operation of punch 33 is substantially identical with that of punch 22 above described, the resulting bales 45 having a passageway 31 therethrough which v provides for ventilation of_ the interior in the manner above described, or for other purposes. positionsy spaced from said slotters, said punches projecting at all times from the face of said plunger and being of a lengthto pass entirely through one ieed'of material. and to penetrate at least partway through the _previous feed whereby repeated strokes of said plunger and punches result in continuous openings through each bale and which openings remain when the bale is removed from the machine.
