Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed September 2, 1904. Serial No. 223,135.

To al whom, it may concern:

Be it known that we, M ELGHIOR L. LU an n as and UMMO F. LUEBBIJN, citizens of the United States, residing at Sutton, in the county of Clay and State of Nebraska, have invented certain new and useful Improvements in Gylindrical-Baling Machines, of which the following is a specification.

This invention relates to the type of machines designed for forming fibrous combustible material into a continuous mat or web and winding the same upon itself to form a cylindrical bale.

A machine embodying the invention is peculiarly adapted for edible fibrous material and enables straw as it is discharged from a threshing-machine and husks as they leave a husking or shredding machine to be formed into a web and rolled upon itself without intermediate handling, thereby materially reduoing the cost of marketing such feed stuff.

The object of the invention is to devise a machine of the character aforesaid which will be entirely automatic in its operation and practically continuous in the performance of work and turn out bales of practically uniform size and diameter throughout their length.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompany ing drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a cylindrical-baling machine embodying the invention, the hind wheel on the inner side being omitted. Fig. 2 is a view in elevation of the machine as seen from the reverse side of Fig. 1. Fi 3 is a central longitudinal section of the feeding, compressing, and bale mechanisms on a larger scale. Fig. 4 is a transverse section of the machine about on the line a:

Fig. 12 is a sectional detail view showing the means for supplying twine for binding the bale after it has reached the required size. Fig. 13 is a front view of the mechanism illustrated in Fig. 12. Fig. 14 is a view in perspective of the rear portion of the machine. Fig. 15 is a detail view showing the means for imparting rotation to the tension-belts and running parts. Fig. 16 is a detail perspective view of the completed bale. Fig. 17 is a detail view in elevation of the bale-forming mechanism and the tension devices cooperating therewith to insure compact winding of the mat or web to prevent a too rapid movementof the parts when returning to a normal position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The framework oithe machine for supporting the working parts may be of any design, according to the capacity of the machine and the particular work intended. As illustrated, the mechanism is mounted upon a truck, thereby admitting of ready transportation from one place to another, which is essential for field service to enable moving the machine from one locality to another, especially when baling the material direct from a tl'i sh husker, or shredder. e

' upper longitudinal timbers 4, transverse tiinroll 7 is mounted in stationary bearings,

able farm machinery.

The framework comprises longitudinal tim bers 1, transverse beams 2, corner-posts 3.

bers 5, and intermediate braces or stays, as may be required to provide a substantial structure. The truck and runninggcar may 1 be of any design commonly employed in port- The means for forming the material into a mat or web comprises com pression- rolls 6 and 7, mounted so as to relatively yield according to the bulk of material passing between them and driven so that their opposing portions move in the same direction to'insure passage of the material therebetween. The lower whereas the upper roll is movable, its bearings being forced downward by springs 8, mounted upon guide-rods 9, receiving set-nuts 10, by means of which the tension of the springs 8 is regulated according to the density of the mat or web to be formed.

The feeding mechanism for supplying material to the compressing-rolls of mat-forming mechanism consists of an endless carrier 11, supported by means of rollers 12 and 13, and a table 14, arranged beneath the upper portion of the carrier 11 and provided at its'longitudinal edges with guards 15 to prevent lateral displacement of the material during its advancement to the mat-forming mechanism. The carrier 11 may be of ordinary construction,such as employed in mill machinery, so long as it serves to move the material over thetable 14. a a

In order to supply the material so as to form a mat of substantially uniform thickness, it is essential that the same be spread evenly upon the carrierv 11, and this is effected by the novel mechanism now to be described and comprising, essentially, two disks 16 and 17, which are arranged a short distance above the table 14 and parallel thereto with their inner edge portions overlapped. The disks l6 and 17 are of such relative diameter as to extend between the guards or side pieces 15 of the feeding mechanism and are secured, respectively, to the lower ends of shafts 18 and 19, mounted in a cross-bar-20, and geared at their upper ends to a transverse shaft 21, preferably by means of beveled gearing 22. The disks 16 and 17 are rotated in opposite directions, as indicated by the arrows in Fig. 7, and in a direction so as to throw the material outward toward the side pieces 15 and insure a uniform distribution upon the carrier and table. The disks are comparatively thin, and-their peripheral portions are preferably sharpened to a knife-edge, so as to cut through husks and other material advancing thereto in bulk. In the operation of the machine a part of the material passes beneath the disks 16 and 17 and a part thereover, the upper portion being retarded, whereas the lower portion is moved forward more rapidly, this be- '1 which arms constitute a part of the levers of which the arms 34 are extensions. The levers, consisting of the arms 34 and 37, are provided with h nbs through which the shaft 35 passes. The arms 3-2 are mounted in coaxial alinement with the shaft 35, and plates 38 are arranged between the hubs of said levers and are likewise ,mounted upon the shaft 35, the projecting ends of the plates 38 being formed with openings 39, through which a rod 40 passes and is connected at its ends to other plates 41, exterior to the series of counterbalanced levers carrying the idlers 29. The lower idlers 30 are mounted upon pins 42, projected laterally from arms 43, loosely mounted upon a transverse shaft 44, arranged below the plane of the longitudinal timbers l and mounted in bearings attached to a crosstimber 45. Each arm 43 is provided with a counterbalanced arm 46, the weight 47 of which is adjustable thereon. The arms 43 and 46 may be of integral formation and are provided with a hub 48 at their point of convergence to receive the shaft 44. Plates 49 are loosely mounted upon the shaft 44 between adjacent hubs 48 and are provided near their outer ends with openings 50, through which a rod 51 is passed.

The part of the tension-belts 28 supported between the rollers 24 and 26 constitutes a traveling bed to support the bale and assists in the formation thereof. The part of the tension-belts 27 supported between the rollers 23 and 25 constitutes a compressing means and supplements the traveling bed in rotation of the bale to roll the mat or web. The bed and compressing means travel in opposite directions, as indicated most clearly by the arrows in Fig. 3. The space between the pairs of rollers 23 and 24 constitutes a throat through which the mat or web passes into the baling-spaces formed between the oppositelytraveling portion of the tension- belts 27 and 28. As the bale increases in size the space formed between the pairs of bale-forming rollers proportionately increases, this being effected by forcing arms 31 and 32 apart, the distance between the rollers of each pair remaining the same. As the arms 31 and 32 are forced apart the idlers 29 and 30 are drawn together, with the result that the weights 36 :..nd 47 are elevated in an arcuate path, thereby proportionately increasing the compression of the bale to its increase in diameter. 1 By ITO nature of the material being baled.

having the idlers 29 and 30 separately mounted upon individual counterbalanced arms, the respective tension-belts are operated upon to insure uniform compression of the bale at every point, thereby compensating for inequalities in the surface resulting from the In this connection it must be remembered that it is practically impossible to provide a smooth surface when baling such material as hay, straw, or fodder. Hence the advantage of the individual tension belts and the separate mounting of the respective idlers therefor.

- A lever 52 is arranged at each side of the machine and is pivotally supported intermediate of its ends. A bar 53 connects one end of the levers 52 with the lower end of the corresponding arm 32, and a bar 54 connects the opposite end of the levers 52 with the upper end of the respective arms 31. Then the balingspace is enipty,the levers 52 occupy the position shown most clearly by the full lines in Figs. 6 and 9, and when the bale has reached the predetermined size the levers 52 assume the position shown by the dotted lines in Fig. 9. Weighted arms 55, pivotally supported at 56, are connected by links 57 to the upper ends of the levers 52. As the opposing ends of the arms 31 and 32 separate the levers 52 approach the perpendicular, with the result that the weighted arms 55 are moved upward at their free ends. hen the levers 52 and links 57 are in alineniient, the weighted arms 55 have reached their highest position, and a continued separation of the arms 31 and 32moves the pivotal connection between the parts 52 and 57 out of a straight line passed through the pivotal support of the levels 52 and the pivotal connection of the links 57 with the weighted arms 55. When this occurs, the superior force of the weighted, arms 55 causes theirouter ends to gravitate and to throw the upper ends of the levers 52 toward the bale and their lower ends away from said bale, thereby pushing the pairs of baling-rollers apart, as indicated most clearly by the dotted lines in Fig. 9, preliminary to the ejectment of the bale, which is thereby facilitated.

The spindle 58, upon which the mat or web is wound, is free at one end and is journaled at its opposite end in bearings 59 and 60 and is provided with a spiral flight or rib 61, which is utilized for ejectment of the bale after same has been completed. A collar 62 is loosely mounted upon a part of the spindle adjacent to the bearing 60 and forms a support for a portion of the drive-chain employed to impart rotation to the bale-forming mechanism. A sprocket-wheel 63 is loose upon an endportion of the spindle 58, and a clutch mechanism is interposed between said sprocket-wheel and spindle to cause the two to rotate jn unisonafter the bale has acquired the given size, so as to rotate the spindle at a higher rate of speed than the bale, with the result that the bale isforced from the spindle by the action of the spiral flight or rib 61. The clutch consists of a pin 64, passed transversely through an opening of the spindle 58, and lugs project laterally from the sprocket-wheel 63. A spring 66, mounted upon the spindle and interposed between the clutch elements, normally holds the parts 64 and 65 separated. An arm 67 is mounted upon the end portion of the spindle 58 adjacent to the bearing 59, and the side of its hub portion facing the bearing 59 is provided with a cam portion 68 to cooperate with a corresponding cam portion of said bearing 59, whereby in the movement of the arm 67 in one direction its cam portion 68, riding upon the companion cam portion of the hearing 59, effects a lateral movement of the arm 67 and the sprocket-wheel 63, thereby throwing the clutch elements 65 and 64 into engagement and causing the spindle 58 and sprocketwheel 63 to rotate together. For operating the pivotally-mounted arm 67 a lever 69 is provided, one end of said lever being connected by means of a pitman 70 with the arm 67, and the opposite end of the lever 69 projecting into the path of a stop 71 of the bar 53 at the side of the machine.

Between the mat-forming mechanism and the bale-forming devices is arranged a support for directing the mat into the throat formed between the bale-forming rollers 23 and 24:. This support consists of a pan composed of similar sections 72 and 73, which have a telescopic arrangement, this being rendered necessary because of the variation of the space between the mat-forming and baling mechanisms incident to the pivotal movement of the arms 31 and 32. The section 72 of the pan is stationary, whereas the section 73 is attached to the arms 31 and moves therewith. The side pieces of the pan are inwardly inclined at the ends adjacent to the arms 31, so as to reduce the width of the mat and compress the edge portions preliminary to its entering the throat leading to the baling-space. A guard 75 is provided at the delivery end of the pan and is inclined upwardly and away from the bale-forming rollers 23 and 24 and insures delivery of the mat or web into the space formed between them.

To prevent loosening of the winds of the mat or web and to insure formation of a bale that will practically maintain its form while being used, the disks 75 are strung upon the shaft supporting the rollers 24 and are loose upon said shaft and project beyond the rollers and upper portion of the tension-belts 28 to insure pressing a portion of one wind into the previous wind or layer. These indentingdisks maybe provided in any number and are arranged between adjacent belts. The indenting-disk 75, adjacent to the delivery side/Jf the machine, has its peripheral port on grooved,

Lil

against opposite sides of the bale, but principally by the method by which they draw together the rollers, by means of the weighted arms 3'7 and 46. The weighted arms 55 also serve to compress the bale by offering a resistance to the separation of the pivoted arms 31 and 32, as will be readily comprehended. The action of these weighted. arms is further supplemented by friction devices, which also serve to prevent a too rapid return of the parts to a starting position after the bale has been ejected. The friction device cooperating with the arms 31 and 43 comprises plates 49, which are strung upon the shaft44 between the hub portions of said arms, a set-screw 7 8 serving to confine the parts upon the shaft 44, so as to obtain the desired object. The rod 51, passing through the openings 50 of the friction-plates 49, serves to limit the inclependent movement of the arms 31 and 43, the play being sufiicient to enable the arms 31 to move so as to take up the slack in the tensionbelts 28 as the bale clears them in its ejectment from the machine. The friction device cooperating with the arms 32 and 34 is similar to that cooperating with the arms 31 and 43 and comprises the plates 38 and the rod 40, as hereinbefore described. The openings 39 in the friction-plates 38 provide for a limited movement of the arms 34, so as to take up any slack in the tension-belts 27 as when the bale clears the same during its discharge.

The levers 52 are secured to a shaft 79, which turns therewith, and upon said shaft 79 is mounted a retarder or friction device consisting of companion arms 80, of resilient material, so as to have a slight spring action. The arms 80 are frictionally mounted upon the shaft 79, so as to turn thereon upon the application of a force sufficient to overcome the frictional contact between the parts 79 and 80. The frictional engagement of the arms 80 with the shaft 79 may be regulated by the set screw or bolt 81. The arms 80 may be of wood or metal, the latter being preferred, and. having an end portion bent so as to encircle the shaft 79 and having a terminal portion extended about parallel with the arm and spaced therefrom and connected thereto by the said bolt or screw 81. The plates 41 are connected to the shaft 35 and turned therewith and are provided with elongated openings 82, in which is supported a rod or bar 83. As the bale increases in diameter the plates 41 and rod 83 move away from the baling-space, whereas the arms 80 .move toward the baling-space, the two para,

41 and 80 moving in opposite directions. The ends'of the arms 80 coming in contact the support 84 drops.

with the rod 83 offer a resistance to the separation of the arms 31 and 32, as will be readily comprehended. As the parts 41 and 80 move in arcuate paths the parts 80 and 83 will clear each other at a point in the movement of the parts 80 and 41, and this occurs at about the time the bale is completed. The rod 83 moves in the openings 82 when riding upon the extremities of the arms 80, and after clearing the latter said rod drops in the openings 82, so as to engage with the extremities of the arms 80 upon the reverse movement of the parts 80 and 41 during the return of the operating parts of the machine to a starting position, so as to prevent their too-rapid movement. hen the bale clears the baleforming mechanism and the arms 31 and 32 approach each other under the action of the weights 36 and 47, the parts 80 and 83 come in contact and regulate the speed of the return movement.

A support 84 is hinged or pivoted at the side of the machine from which the bale is discharged and is provided with companion rolls 85, upon which the bale 86 rests during its ejectment. A sectional brace holds the pivoted support 84 in the horizontal position, as shown most clearly in Fig. 10, the sections of the brace being indicated at 87 and 88. A trip 89 is pivoted to the lower projecting end of the section 88 and is adapted to be struck by the outermost pivoted arm 43, or rather by a stop 90 connected thereto. As the bale clears the last'set of tension-belts the arms 31 and 32 close and the counterbalanced arms 34 and 43 correspondingly move, with the result that the stop 90, coming in contact with the trip 89, breaks the joint of the sectional brace sustaining the support 84 and permits the latter to drop at its outer end, as indicated by the dotted lines in Fig. 10, whereby delivery of the bale is effected. An extension 91 projects from the support 84, and a rod or bar 92 is in contact therewith and is moved upward as The upper end of the rod or bar 92 is bent laterally, as shown at 93, and extends across the path of the adja: cent weighted arm 55 and lifts the latter. As soon as the support 84 is relieved of the weight of the bale the weighted arm 55 returning to a normal position presses downward upon the rod 92 and resets the support 84, as indicated by the full lines in Fig. 10. WVhen the bale has acquired the given size, the feeding mechanism is automatically thrown out of gear to prevent a supply of material during the binding and discharge of the bale. The instant the bale has cleared the machine the feeding mechanism is automatically thrown into gear. These portions are effected by the mechanism now to be described.

A sprocket-wheel 94 is loosely mounted upon the shaft 95 of the inner supportingroller 13 of the carrier 11 and is normally IIO pressed outward by means of a spring 96, mounted upon the shaft 95 and confined between the sprocket-wheel 94 and a pin or stop of said shaft. An arm 97 is loosely mounted upon the shaft 95, and its hub end is provided with a cam portion 98 to cooperate with a corresponding cam portion of a collar 99 in coaxial alinement with the shaft 95. A clutch is interposed between the shaft 95 and sprocket-wheel 94 and, as shown, consists of a pin 100, fitted inan opening of the shaft 95, and lugs 101, projected laterally from the sprocket-wheel 94. Upon turning the arm 97 it is moved laterally by reason of its cam portion 98 riding upon the cam portion of the part 99 and being in contact with the sprocketwheel 94 moves the same against the tension of the spring 96 and engages the clutch by moving the lugs 101 out of the path of the projecting ends of the pin 100. The arm 97 is connected to a weighted arm 102 by means of a rod 103, and said weighted arm 102 is attached to a rock-shaft 104, mounted in bearings attached to the cross-timber 45 and provided with a trip 105, to be engaged by means of an arm 106, attached to or forminga part of one of the arms 43 and 46. The rock-shaft 104 is actuated at the instant the bale reaches the predetermined size, and the pivoted arms 31 and 32 are forced apart by means of the weighted arms55 in the manner stated. As the arms 31 and 32 close and the arm 106 moves away from the trip 105, the weight applied to the arm 102 serves to rock the shaft 104 and move the arm 97, so as to permit the sprocket-wheel 94 to become clutched to the shaft 95, whereby the feeding mechanism is thrown into gear.

The means for feeding the binding-twine to the bale comprises anarm 107, which is attached to a rock-shaft 108 and is adapted to be engaged by a projection 110, extended from the pivoted arm 31 at the delivery side of the machine. The arm 107 is provided with a guide 111 for the binding-twine, and its upper end is curved and made concave in cross-section. The roller 112 is journaled to the upper portionof the arm 107 and operates, through the opening formed therein, so

5 as to come in contact with the outermost indenting-disk 75, so as to be rotated thereby and automatically feed the twine to the bale. Normally the arm 107 stands away from the bale-forming mechanism; but when the bale has reached the required size and the arms 31 and 32 are forced apart by the weighted arms 55 the projection 110, striking the trip 109, rocks the shaft 108 and throws the arm 107 toward the rollers 24 and brings the roller 112 in engagement with the outermost indenting-disk 75, and the twine 77 being confined between the roller 112 and the indenting-disk automatically and positively advances the twine to the bale.

of a disk 113, attached to or forming a part thereof, said disk being in contact with the series of rollers 23, 24, 25, and 26. This is indicated most clearly in Figs. 3 and 11. After the spindle has received a number of winds of the mat or web the roll is thereafter rotated, by means of the tension- belts 27 and 28, in the manner hereinbefore stated.

The compression-rolls are geared together in any determinate way so as to rotate at uniform speed and in opposite direction. The sprocket-wheel 94 is connected, by means of a sprocket-chain 114, to acompanion sprocketwheel 115, mounted upon an extension of the shaft of the lower eompression-roll 7. A twin sprocket-wheel 116 is attached to the shaft of the upper compression-roll 6, and sprocketchains 117 and 118 pass around the respective members thereof and around sprocket-wheels 119, applied to the journals of the series of bale-forming rollers 23, 24, 25, and 26, so as to drive the tension- belts 27 and 28 in opposite directions. An idler 120 supports the opposite ends of the sprocket-chains 117 and 118 and is journaled to a pivoted support 121, to which a movable bar 122 is connected and acted upon by means of a spring 123 to maintain the sprocket-chains 117 and 118 under a given tension and by means of which any variation due to the relative movement of the 5 pairs of rollers 23 and 24 and 25 and 26 results. A sprocket chain 124 connects a sprocket-wheel125 with thesprocket-wheel63.

In the operation of the machine the material to be baled is supplied to the carrier 11 and advanced thereby to the compressionrolls 6 and 7, by means of which it is formed into a mat or web. This mat or web passes along the pan to the bale-forming mechanism and is wrapped about the spindle 58. After the bale has reached the predetermined size the feeding mechanism is thrown out of gear in the manner stated, and the spindle 58 is thrown into gear with actuating mechanism, by means of which it is rotated at a higher rate of speed than the tension- belts 27 and 28, and as a consequence has imparted thereto an endwise movement which forces it from between the tension-belts. During the operation of discharging the bale the tensionbelts cleared are successively straightened between the respective rollers 23 25 and 24 26. The indenting-disks form aspiral groove or indentation in the outermost layer of the bale as the same is discharged, and the bindingtwine 77 is correspondingly wrapped about the bale in a spiral direction. The finishing end of the binding-twine after being cut is tucked under the last wind of the twine by hand. The starting end of the binding-twine is automatically caught under the first wind. Hence the only operation to be performed by hand is the tucking of the finishing end of the binding-twine under the last wrap. The binding-twine is automatically cut by means of a knife126, applied to the upper end of the arm 107. The disk 113 is located at the inner end of the spindle at the beginning of the spiral 61 and acts as a head to prevent the material working toward the bearings and gearing cooperating with the spindle.

It is noted that the bolts 27 and 28 may be more cheaply produced, are more durable, and operate more effectively than a single wide belt,- because the strain is unilbrn'ily distributed thereon, and any elementmaybe replaced at a comparatively slight expense. Moreover, the belts admit of a shifting of the traveling beds or carriers upon the rollers 23, 24, 25, and 26 as the bale is ejected by means of the spiral 61. The rollers 23 and 26 are longer than the rollers 24 and 25 to admit of the tension-belts shifting thereon when the bale is discharging.

Having thus described the invention, what is claimed as new is 1. In a cylindrical baling-machine, the combination of oppositely-disposed bale-forming belts, pairs of supporting-rollers therefor, the rollers of each pair sustaining opposite belts, a movable support for each pair of said rollers, idlers for tensioning the belts, and movable supports for the idlers to admit of maintaining the belts under tension during all stages of the bale, substantially as set forth.
