SPECIFICATIGN forming part of Letters Patent N 0. 676,511, dated June 18, 1901.

Application filed October 11, 19001 To all whom it may concern-.-

Be itknown that I, JOHN PEGG, a citizen of the United States, residing at Bloomingport, in the county of Randolph'and State of Indiana, have invented certain new and useful Improvements in Baling-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to automatic hay or straw balers.

The object ofthe present invention, broadly speaking, is the provision of an improved machine of the class described whichwill automatically take in the hay or straw, compress it into a bale, discharge the completed bale and wire it, and repeat these operations as long as kept in action.

To accomplish the foregoing object and others not specifically mentioned, I provide a baler-wheel provided with baling boxes or chambers and plungers or followers of improved construction, together with novel latches therefor, whereby the bales can be formed in succession and discharged after formation; also, improved feeding mechanism for takingin hay or straw in'position for delivery into the baler-chamberin which the bale is to be formed and a peculiar and novelbale forming and packing device and allied mechanisms, together with improved and novel means for discharging or ejecting the formed bale after rotation of the baler-wheel and during the formation of a new bale, and various novel automatic mechanisms allied to and cooperating with those aforesaid whereby the entire action of the machine is automatic.

The details of the inventionand the mannor of operation of the difierent mechanisms will be fully set forth hereinafter and the novel features recited in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of one of the bale-discharging mechanisms; Fig. 2, an end view thereof; Fig. 3, a plan View thereof; Fig. 4, a plan view of the complete machine; Fig. 5, a side elevation of the complete machine; Fig. 6, an end View of the mechanism for operating the bale-discharging device; Fig. 7, a side Serial No. 32,7762 (No model.)

view thereof; Fig. 8, a front end elevation of the machine; Fig. 9,a rear end elevation thereof;.Fig. 10, a vertical. section on the line 00 02 of Fig. 9; Fig. 11, a side view of the 'baler-wheel, and Fig. 12 a vertical section therethrough; Fig. 13, a perspective view of several of the mechanisms on one side of the machine and looking outwardly; Fig. 14, a

Fig. 19, a detail of the mutilated gear; Fig.

20, a View similar to Fig. 18, but showing the eccentric unclutched and the mutilated gear clutched and other'parts shifted; and Fig. 21, a detail showing the manner of locking the actuating-bolt of the rocker.

The frame 1 of the machine supports all of the different mechanisms, and from this rises a frame 2, carrying a plunger-frame 3. On the main frame is a bale-compressing box 4, which is of the same size at its receivingmouth 5 as will be the bale in the baler-wheel, but is considerably smaller for the balance of its length, being suitably tapered, so that the bale is compressed and compacted before it is wired or wrapped and ejected from the machine.

The numeral 6 designates an arc-shaped guard-plate connecting the compressing-box to the feeding-chute 7 and which retains the bale in the baler-wheel until it arrives in position to be forced into the compressing-box.

' The main or power shaft of the machine 8 is journaled in suitable boxes on the main frame and carries on one end a fly-wheel 9 and on the other end a band-pulley 10, by

which the machine is driven.

Thebaler-wheel 11 is provided with'short hollow shafts 12 and 13, projecting from its opposite sides, which are journaled in suitable bearings on the frame and through which the, power-shaft 8 loosely passes. Squared portions 14 are provided on the shafts, and over them are fitted the gears 15,

through whose agency the baler-wheel is in termittently turned. This baler wheel is composed of a rim 16 and a plurality-in the present instance fonr-of bale chambers or boxes 17, all suitably braced and connected to give the necessary rigidity and strength. The boxes or chambers are closed at their inner ends and open out through the rim at their outer ends in the months 18, through which the hay or straw is fed into them in the first instance to form the bale and through which the bale is afterward ejected into the bale-compressing box. In the sides of the bale chambers or boxes are slots 19, in which travel the arms 20 of plungers or followers 21, which are free to move in the boxes and which afford a bottom against which the hay or straw is pressed while the bale is being formed in the chamber or box and which are utilized to eject the completed bale afterward through the mechanism described hereinafter. Adjacent the mouth of each bale box or chamber and on opposite sides thereof are gravity locking-latches 22, having the heads 23 and slidable in guides 24. These latches are adapted to drop by gravity and engage the arms 20 to lock the plungers or heads 21 when opposite the bale-compressing box 4 after the bale has been discharged thereinto and will keep the plunger locked when it is at the bottom of the baler-wheel but said catches drop back by gravity and unlock the heads or plungers before the box or chamber,

in which they are located, reaches the top of the hater-wheel in order that the head may drop to the bottom of the box and the box be free to receive the hay or straw, which will then be compressed thereinto by the mechanism provided for that purpose.

Sli dable up and down on suitable guides 25 in the plunger-frame 3 are two spiders 26 I and 27, which are connected by a sleeve 28,

within which slides the plunger-shaft 29, carrying an adjustable head 30 on its upper end and a packing-plunger 31 on its lower end, the latter having a vertical web or portion 32' and being of suitable size to snugly yet easily titthe boxes 17. A coil-spring 33 encircles the shaft 29 between the spider 27 and a catch 34 on the plunger, while another coil-spring 35 surrounds the said shaft between the spider 26 and the adjustable nut or head 30. The plunger is thus made free for movement not only with the spiders but independently of them, the springs cushioning the blows of the plunger on the material being baled as the bale increases in length, thereby preventing breakage during the formation of the bale, and not only this, but they provide means for restoring the plunger to its proper position after it has been tripped loose preparatory to the formation of anew bale. Depending from the spider 27 isa hanger 36, to which is pivoted a link 37, which in turn is pivoted to a catch 38, provided with a slot 39 and normally held downward by aspring 40, surrounding it and interposed between the link 37 and a trip-bolt 41, sliding loosely through the hanger 36 and a guide 42, and provided with-a catch 43. The trip-bolt 41 is provided with a notch 44, into which the catch 38 is adapted to snap when the trip-bolt is pushed toward the right against the action of a coil-spring 45, which has a tendency to urge it toward the left. Secured to the frame 3 is a trip 46, against which the end of the trip-bolt 41 strikes when the spiders are raised to the positions shown in Figs. 5 and 10, whereby the said trip-bolt is urged toward the right and locked by the catch 38. After the bale has been completed the plunger 31 will be operating at the mouth of the balebox and the lower end of the catch 38 will ultimately strike the plunger 31, forcing the said catch upwardly and releasing the tripbolt 41, which will thereupon snap to the left and the catches 34 and 43 will engage, thereby locking the plunger to the spiders, whereupon certain mechanisms to be described hereinafter will be brought into play and the reeiprocations of the plunger stopped, the baler-wheel rotated a quarter-turn, so that the finished bale may be discharged, after which the bale-forming mechanism will be again made active and the spiders and plunger raised until the plunger is again tripped loose by the engagement of the trip-bolt 41 with the trip 46, whereupon the formation of the new bale will be commenced, a quantity of the hayor straw being fed meanwhile into the bale-box.

The mechanism for reciprocating the packing or compressing mechanism whose operation has just been described consists of duplicate levers 47, pivoted to suitable standards at 48, pitmeu 49, connecting the free ends of the levers to the spider 26, levers 50, pivoted to hangers 51 and having cars 52, and pitmen 53, connecting the free end of the lever to the levers 47. The specific means too for actuating the lever 50 will be described hereinafter in connection with certain mechanisms which cooperate therewith.

In the feed-chute 7 are positioned the feeding-rakes 54 and 55, which have their heads pivoted in the sides of the chute. The rakes have the respective oppositely disposed

cranks

56 and 57 on their ends, said cranks being connected by a connecting-rod 5S and the crank 56 being also connected to one of the levers 47 by a connecting-rod 59. The reciprocations of the levers 47 therefore cause the feeding-rakes to oscillate in opposite directionsthat is, toward and away from each other-whereby the rake 54 draws in the hay or straw and the rake 55 afterward pushes it into the bale-box inthc baler-wheel which is undergoing filling. Above rake 55 the chute is provided with a guard (5O to insure the retention of the material i n the chute while being fed therefrom.

The mechanisms now to be described are duplicated on opposite sides of the balerwheel, differing'from each other in immaterialparticulars only, and hence a description of the mechanisms at one side of the machine only will be given.

The numeral 61 designates a shaft having a gear 62, by which it is driven from a counter-shaft 63, through the agency of a pinion 6a. The counter-shaft 63 hasa gear 65, which is in mesh with a pinion 66 on the drivingshaft 8. On the inner end of the shaft 61 is a mutilated gear 67, having a clutch member 68 and loose on the shaft. This gear is adapted to mesh with the gear 15 at times when the bale-box into which the hay or straw is being pressed becomes full, and as the mutilated portion of the gear 67 occupies threequarters of its periphery and the teeth or spurs the remaining one-quarter this mutilated gear can only accomplish the turning of the balerwheel through one-quarter of a complete revolution or until the bale-box which has been filled is opposite the bale-compression box 1. Loosely mounted on the shaft 61 is an eccentric 69, whose rod 70 is pivoted to the lever 50. This eccentric has a clutch member 71, facing the clutch member on the mutilated gear 67. On the shaft 61 and between the clutch members 68 and 71 is a slidable double clutch 72, said double clutch being slidable on a key or spline, so that it will always turn with the shaft 61. The distance between the clutches 6S and 71 is such that the double clutch 72 will be engaged with either, but not both, of them at a given time. A bevel-pinion 73, having a clutch member 74, is loosely mounted on the shaft 61, and said shaft carries a second sliding clutch 75, by which the said pinion is locked to the shaft or unlocked therefrom as said clutch 75 slides on a key and turns with the shaft. The

clutches

72 and 75 are shifted simultaneously through the agency of a clutch-shifter 76, having

arms

77 and 78 connected to the clutches in the usual manner, said clutch-shifter being slid able in portions of the frame of the machine and being urged in a direction outwardly from the baler-wheel by a spring 79, whereby the clutch 72 is normally held engaged with the eccentric 60 and the clutch 75 is kept disengaged from the pinion 73.

Extending lengthwise of the machine and suitably journaled is a wabble-cam shaft 80, carrying a wabble-cam 81. On the end of said shaft is a bevel-pinion S2,which has notch or pocket 83. An arm 84, forming a part of the clutch-shifter 76, is normally receivedin said notch, thereby locking the wabble-cam shaft and pinion.

The numeral designates an arm rising from the main frame adjacent the side of the baler-wheel. A baler-wheel lock-bolt 86 slides through the end of this arm in position to form an abutment for the arm 20 of the plunger, which is uppermost onthe baler-wheel that is, the arm of the plunger of the balebox which is being filled. The baler-wheel is thus prevented from rotating forwardly while the bale is being formed. This lockbolt is provided with an arm 87, sliding through a suitable guide, and the bolt is held normally projected bya spring 88. The arm 87 extends down alongside of an eccentric wiper-cam 80, secured on the wabble-cam shaft 80. V7 hen therefore the bale has been finished and through the intermediate mechanisms now to be described the clutches have been shifted to throw the eccentric out of engagement with its shaft, and the mutilated gear and the bevel-pinion in engagement with said shaft, the bevel-pinion on the wabble-cam shaft will become unlocked and the wabble-cam shaft being thrown into rotation the wiper-cam will withdraw the locking-bolt, and the mutilated gear will then turn the baler-wheel one-quarter of a complete revolution, after which the said wheel will again be locked.

Referring now more particularly to Figs. 1, 2, and 3, the numeral 90 designates a frame or body of the bale-compressor and bale-ejecting mechanism. This consists of an elongated open box-like frame having a screwshaft 91 journaled in its ends and carrying pinions 92 and 93 on its extremities. A nut 91 is located on the threaded portion of the shaft, with its ends projecting through the open sides of the frame, as at 95 and 96. It will be seen that any rotation of the shaft 91 will cause a movement of the nut longitudinally of the frame, and as the projecting end 96 is arranged to engage with the arm 20 of the plunger of the box, which is in alinement with the bale-compression box 4, the plunger must advance toward the said box 4 with the nut, and consequently the bale will be forced into the box 4. On opposite sides-that is, the top and bottom-of the frame 90 are located sliding catches 07, which are duplicates of each other, but are reversely arranged. Each catch has a locking-head 98, arranged to project over the end of the frame adjacent the pinion and provided with slots 99 to loosely receive short bolts 100, screwed into the frame and holding the ends thereto, said bolts acting as guides to prevent lateral displacement of the locking-head. At the opposite end of the sliding catch is a retract-ing head 101, having the fingers 102, which straddle the frame 90, and this end of the catch is guided by a slot-andbolt construction 103.

The numeral 104 designates a yoke secured 'to the frame 90 at its precise center or intermediate its ends, which is provided with a stub-shaft 105,suitablyjournaled in the frame 1. The catches 97 are kept normally urged in opposite directions by springs 106, surrounding rods 107, which are secured to the catches and slide loosely through the projections 108 on the yoke. The tendency of the springs is to keep the locking-heads 98 projected beyond the ends of the frame 90 at all times except when the nut M is at the ends of the frame and engaged with the fingers 102, whereupon the locking-head will be retracted from its abutment on the stop portions 109 of the frame 1, making it possible to rotate the entire -bale compressing and ejecting mechanism in a counter-clockwise direction, so that the projecting locking-head of the catch on the opposite side of the frame can be made to assume the position formerly occupied by the retractedlocking-head, and the nut 94 will then be in position to act on the succeeding bale-box plunger in a similar manner.

To provide for the rotation of the screw of the bale-compressing mechanism, the. following gearing is used: A shaft 110, provided with a gear 111, in mesh with pinion 66, has a bevel-gear 112, meshing with a bevel-gear on a short shaft 113, which carries a pinion 114, meshing with a pinion 115, which latter is in position to mesh with either the pinion 92 or the pinion 93 of the bale compressing and ejecting mechanism. The rotation of the pinion is such that its meshing with the pinions 92 and 93 tends to hold the lockinghead 98 down on the stop portions 109, thus keeping the compressing mechanism in proper position to do its work.

On the stub-shaft 105 is secured a double cam 116 of the wiper or trip type.

The numeral 117 designates an arm which is pivoted to frame 1 at 118 and has fingers 119 at its upper end, which embrace the edge of the wabble-cam 81, whereby it is oscillated. Another arm 120, provided with a head 121, through which the reduced lower end of the arm 117 projects, is pivotally mounted on the frame at 122. An actuating-rod 12 3, sustained by a spring 124, fastened to the frame, is pivoted at one end to the upper end of the arm 120 and has its other end bent and adapted to engage with the. shoulders of the cam 116, the spring keeping it on the cam. The action of this mechanism is such that when the wabble-cam shaft 80 is turned the bale-compressing mechanism will be completely reversed in a counter-clockwise direc-,

tion by the coaction of the rod 123 with the cam 116.

The bale tying or wiring device 126, which operates across the mouth of the bale-conipression box 4, is of an ordinary type adapted to the purpose and is reciprocat-ed back and forth by a pitman 127, connected to a crank 128 on the end of the wabhle-cam shaft at one side of the machine.

Ihe numeral 129 designates a rocker which is pivotally mounted on theframe at 130 and provided with an arm 131 at its lower end, which is pivotally connected to a pivoted lever 132, which has its other end adapted to bear against the clutch shifter 76. rocker has a laterally-movable actuating-bolt 133, which is urged toward the baler-wheel by a spring 134, and it is provided with. a notch 135 on its lower edge and a finger 136 at its outer end, which is engaged with a pivoted lever 137, in turn workingin connection with another lever 138,. which has its end straddling the arm 87. The arrangement of This.

levers is such that when the arm 87 is pushed aside by the wiper-cam 89 the actuating-bolt 133 is pulled outwardly-that is, retracted against the action of its spring. To secure the actuating-bolt in its retracted position,

the sliding catch 139 is provided,

the'same

72 and 75, thus throwing the bale forming or packing mechanism out of operation and unlocking and putting into operation the wabble-cam shaft and unlocking the baler-wheel, resulting in the bringing of the bale compressing and ejecting mechanism into operation. However, the actuating-bolt 133 is not normally projected, and the levers 50 and bale packing or forming mechanisms operated thereby are left free to continue to operate until the slidingcatches 139 are depressed, which is accomplished by the following mechanism:

The numeral 141 designates a dog which is pivoted to a bracket 142 and has one end resting on the upper end of the catch 139 and its other end provided with a tooth 143, which rests on a ratchet-wheel 144.

The numerals 145 designate levers which are pivoted at 146 and joined together by a loose connection at 147, where they are. provided with an ear 148. Connected to the ends of the lovers are pawls149, adapted to engage the ratchet-wheels. The car 148 is located in such a position that at the time the trip-bolt 41 is released bythe engagement of the catch 38 with the packing-plunger 31 it engages with said ear, and the action of its im-pelling-spring,together with the continued downward movement of the spider,causes the lovers 145 to be moved, which results in a turning of the ratchet-wheels and alifting of the dog and downward movement of the catches 139, thereby releasing the actuatingbolts 133, which are then engaged by the ears 52, whereupon the pressure of the levers 50 causes a movement of the rockers 129 and a shifting of the clutches and consequent throwing out of operation of the packing or bale-forming mechanism and the throwing into operation of the other mechanisms, as previously explained. As these other mechanisms operate and complete their function the actuating-bolts 133 are retracted and the parts return to their normal positions, whereupon the packing or bale-forming mechanism resnmes its operation.

Having thus described my invention, what I- claim as new, and desire to secure by Letters Patent, is
