PAPER-BALING MACHINE.

Application filed July 1, 1921.

T all whom it may concern Be it known that 1, WILLIAM A. ULLn, a citizen of the United States, and residing at St. Louis, Missouri, have invented the new and useful Improvement in Paper-Baling Machines, of which the'following is a specification.

This invention relates to baling or packing machines, and more particularly to a iachine for baling or rolling newspapers.

Preliminary to delivering newspapers to subscribers, the carrier is usually under the necessity of rolling or baling the papers in some manner so that they may be conveniently delivered by throwing them to the customers premises from a moving wagon or cart. It will be readily seen that when a carrier has to deliver in the neighborhood of fifteen hundred papers, that the time consumed in rolling may be very considerable. As it is customary to roll all of the papers before starting over the delivery route, the result is that from one to three hours may be consumed in rolling papers before the start can be made.

One of the objects of this invention, therefore, is to provide means for rapid rolling of newspapers into a form convenient for rapid delivery.

Another object of this invention is to provide such rolling means which shall be light and portable so that it may be carried on the delivery cart.

Another object of this invention is to provide a device whereby the papers, being stacked upon a receiving tray, may automatically be fed to the machine, rolled, tied and ejected.

Further objects will appear from the following description taken in connection with the accompanying drawings, in which:

Figure l is a view in end elevation showing a machine. embodying this invention;

I Figure 2 is a side elevation, partly in section;

Serial No. 481,808.

Figure 12 is an enlarged detail of the wire guide; and

Referring to the accompanying drawings, 1 designates a base which may be of cast iron and which may be provided with screws 2 by means of which feet may be attached to the base, upon which the machine may stand or said base may be bolted to a bracket for mounting on a wall or on a wagon or cart. Mounted on the base 1 at each end thereof is anend housing 3 which encloses part of the operating mechanism and which is closed by an end plate t. A pair of tire rods 5 pass across the machine from one to the other of the housings 3 so as to support and brace the same. These tie rods also serv: as pivots for certain parts as will be hereinafter described. Pivoted on a rod 6 supported by the housings 3 is a link 7 to the other end of which is pivoted a receiving rack 8 for the papers. rack 8 is further supported by a pair of toggle links 9 and 10, pivoted at 11 to the rack 8 and at 12 to the housings 3, there being, of course, a link 7 and a pair of toggles 9 and at each end of the machine.

The receiving rack 8 is provided with a pair of spring catches 13 fixed to the underneath side thereof, each having an Lip-turned end adapted to protrude above the lower edge of the rack so as to retain the papers stacked therein as will be clearly seen from Figure 3. The papers are placed upon the receiving rack 8 in a pile or stack with their folded edges down and are swayed backward so as to lean against the rear end of the rack 8. A swayed stack is thereby formed from which papers may be fed individually from the bottom and as each paper is fed, the succeeding one will move downward to replace it. The catch 13 will, however, retain the papers until operated to release them as hereinafter described.

?ivoted on the rod 6 is a feeding hopper let having a side plate 15 adapted when in receiving position to aline with the inclined bottom of the rack S. This plate 15 is adapted, when in receiving position, to engage the up-turned end of the catch 13, forcing this end downward so as to release the first paper which will thereupon slide down into the hopper lat. Located at the upper edge of the plate 15 and between the catches 13 is a The receiving 'ing position (as shown in Figure 3) the end 18 will be depressed so as not to interfere withthe downward movement of a paper when released by the catch 13. Thus, as the paper is released to move onto the plate 15,

passing over the tip-turned edge 18 of the stop 16 and down, will engage the tail 19 pushing the same downward and at the same time raising the edge 18 in time to engagethe edge of the succeeding paper to prevent the same from following the first paper. The paper will then move down to the position shown in Figure 5, in which it will still be resting upon the tail 19 so as to hold the edge 18 in position to engage the succeeding paper to retain the same in place.

The lower portion of the hopper 14 is provided with a narrow neck 20 whose axis makes an angle with the plate 15. Pivoted on brackets 21 formed onthe lower portion of the hopper 14 is a pair of stops These stops are loosely pivoted and are adapted to rest by their own weight against the main shaft 23. The'stops 22 are each provided with a crotch 24 adapted to catch the lower edge of the paper when fed downward by the movement of the hopper 14, to be hereinafter described. This position of the paper is illustrated in Figure 4. The stops 22 serve to retain the paper in position for engagement by the rolling mechanism as will be hereinafter described. 7

The main shaft 23 is mounted in bearings in the end plates 4 and carries at its outer end a gear 25 adapted to engage a pinion 26 which is adapted to be turned by an operating crank 27 for rotating the shaft The outer edge of each housing 3 is pro vided with an internal gear 28 adapted to engage a gear 29 mounted for planetary movement on an arm 30 keyed to the shaft- 23. The gear 29 is carried by a shaft 31 mounted in a bearing 32 on the arm 30. Splined to the shaft 31 is a plate 33 which is embraced by a grooved, split collar 34 having trunnions adapted to engage a stirrup 35 on an arm 36 pivoted at 37 to the hub of the arm 30. The lower end of the arm 36 is pivoted to an adjustable head 38 on a sliding pin 39 arranged for sliding movement through an extension 40 of the arm 30. The head 38 and the extension 40 are connected by a tension spring 41. The end of the pin 39 is adapted to bear against a cam surface 42 formed on the end plate 4. As the arm 30 rotates with the shaft 23, the pin 39 will be carried over the cam surface 42 which will cause said pin to more back and forth through the extension 40, thereby moving the arm 33, which in turn moves the plate back and forth along the shaft 31 to which it is splined. A lost motion connection is provided between the stirrup 35 and the collar 34 so as to allow for such movement. The plate 33 is flanged upon its edge and the collar 34- is correspondingly grooved in a well known manner so as to allow for rotation of said plate within said collar. It will be readily understood that as the arm 30 rotates with the shaft 23, the shaft- 31 will be rotated in its bearing 35, by the gear 29 in mesh with the internal stationary gear 28. It will thus be seen that the plate is given a combined rotary and reciprocating movement according to the rotation of the shaft 23.

The plate 33 is provided with a pair of pins 43 fixed therein and adapted to provide a fork to engage the paper for rolling the same as will be hereinafter more fully described. Duplicate mechanism to that just described is arranged in the other housin 3.

Tivoted on one of the brace rods 5 is a wiping plate 44. This plate has a curved form following approximately the path of the plate 33 in its rotation about the shaft 23 and is provided at its lower extremity with an extension 45 which is pivoted to an arm 46 which is in turn pivoted to a bracket 47 mounted on the base 1. A stout spring 48 holds the arm 46 in raised position as shown in Figure 3.

The'hopper 14 is provided with a downwardly extending arm 49 which is adapted to engage one of the pins 43 in its travel about the shaft 23 so as to tilt the hopper about its pivot 6 to receiving position, as shown in Figure 3. As said pin 43 moves out of engagement with the arm 49, a tension spring 50 attached at one end to the bracket 21 on the hopper andat its other end to an ejector plate 51 o )erates to swing the hopper about its pivot 6 delivery position as illustrated in Figure its the hopper assumes this position, the paper will drop through the neck 20 and will lodge in the crotch 24 of the stop The paper will be held in this position until the movement of the plate 33 brings the pins 43 into engagement therewith. The movement is such that one of the pins will pass under the lower edge of the paper to one side ther' of, while a second pin will engage the other lli) side. The paper will thus be caught between two pins at each end of the machine. The movement of these pins adapted to accomplish this purpose is indicated in dotted lines in Figure 4. Immediately after one of the pins 43 has passed under the lower edge of the paper held in the crotch 24, said pin will engage the arm 29 as to rock the hopper back to receiving position. As the hopper moves back to such position, the paper held in the neck 26 will be swept out of the crotch 24 and allowed to drop vertically until its lower edge rests upon the plate 44 near the bottom of the machine. This position is illustrated in Figure 5. Further movement will cause the pins 43 to engage the paper on opposite sides between the edges thereof and at a point nearer to one edge than the other. As the movement progresses the paper will be folded by the turning of the pins 43 which now move with the combined movements of rotation and translation so as to carry the paper downward along the plate 44, the paper being wiped or brushed against the plate 44 which assists in rolling the paper about the pins. As the paper rolls down along the plate 44, it will press this plate to the right, Figure 3, and since this plate is pivoted at 52 to the arm 46, said arm will be moved downward about its pivot on the bracket 47 for the purpose of performing a tying operation which will now be described.

Mounted on the underneath side of the rack 8 is a reel 53 adapted to hold a supply of wire or other suitable tying means by which the paper may be secured after it has been rolled. The wire passes off of the reel 53 about a rooved wheel 54 mounted loosely on the shaft 23 and thence to a pair of jaws 55 and 56 in which the end is gripped. The jaws 55 and 56 are mounted on the end of the arm 46, one of these jaws 56 being arranged to lie within a groove in the other jaw 55 and being provided with teeth 57 in which the wire may engage. The jaws are firmly pressed into intimate engagement by a compression spring 58 suitably mounted in one of the jaws 55. The arm 46 also carries a wire guide 59 having in the end thereof a flared notch 60. As the arm 46 is drawn downward by the movement of the plate 44 in response to the pressure of the paper being rolled thereagainst, said arm 46 will be depressed through an opening 61 proi'ided in the plate 44 for that purpose and will carry with it the end of the tie wire which is securely held by the jaws 55 and 56. This carries the wire down in front of the advancing paper to such a position that the subsequent movement of the paper will carry it against the wire to form a bight therein to which the paper is delivered by such movement.

Loosely mounted on the shaft 23 is an arm 62 having an extension 63 adapted to be engaged by the paper in its travel. This arm carries a pair of spring clips comprising a pointed central shank 64 provided on each side with a flared flat spring 65 adapted to bear against the sides of the shank 64 with considerable pressure and to form at their ends flared notches 66 and 67. Mounted on the shank 64 is a small bevel gear 66 adapted to mesh with a corresponding bevel gear 69 mounted for rotation with the shaft 23. The gear 69 has part of its periphery cut away so as to be elfective only during part of the complete revolution. Also mounted on the shank 64 and arranged to lie on the opposite side of the gear 68 from the notches 66 and 67 is a wire guide 70 having afiared notch 71 adapted to guide the wire into the notch. The relation of the parts is such that when the arm 46 is in raised position, the shank 64 with its gear 68 and the wire guide 70 will lie between the jaws 55 and 56 and the wire guide 59 which are spaced from each other for that purpose. Pivoted at 72 on the opposite side of the shank 64 from the gear 68 is a wire cutting blade 73 having a cam shaped edge 74 adapted to be engaged by the flat edge 75 of the gear 69, being thereby moved inwardly to cut off the wire held in the clip 66.

As the paper engages the tie wire as shown in Figure 6, further movement will cause it to form a bight in the wire, carrying the strand up-ward around the wheel 54 so as to bring the strand 76 between the paper and the wheel 54 upward to engage the notch 66 and passing the wire upward under the spring 65 on that side to securely hold the strand. This movement of the paper will eventually release pressure thereof against the plate 44 so as to allow the arm 46 to return to raised position, which movement takes place after the paper has passed the position of Figure 6. This movement of the arm 46 will carry the strand 77 between the paper and said arm to wrap it about the underside of the paper and bring the end up to the position in Figure 7. Durin this movement the strand is caught in the notch in the guide 59 whereby it is carried into the notch 67 so as to be caught under the other spring to pe securely held thereby. Further rising movement of the arm 46 will now carry both strands upward into the notches 66 and 67 passing the strands on opposite sides of the gear 68 and into the flared notch 71. The paper is now held in the bight of the tie wire. the ends of which are brought together into the notch 71, passing thence on opposite sides of the gear 68 to be held under the springs 65 on opposite sides of the shank 64, one of these wires passing thence through the jaws 55 and 56 and to the grooved wheel 54. The movement of the shaft 23 now brings the edge 75 of the gear 69 into ongagement with the cam-shaped edge 74 of the cutter 73 moving said cutter inward to cut off the wire, the end being still retained however, in the jaws 55 and 56 so as to be ready to repeat the operation on the succeeding paper.

The loose ends of the wire are still held under the spring 65. Further movement of theshaft 23 will now carry the gear 69 into engagement with the gear 68 to rotate said gear 68. As the strands of the tie wire have been brought over opposite sides of this gear, they will be caught in the teeth thereoi and carried around by its rotation so as to twist theseends about each other, the twist lying within the bottomof the notch '21. and the loose ends being gradually drawn out from under the springs by the twisting movement. During this operation the paper has been advancing with the movement of the pins 54 until it engages the arm 63 whereupon this arm will be raised with the movement or the paper.

The paper is now completely rolled and tied but is still supported on the pins 43. The movement of the shaft 23 now brings the pin 89 to the raised portion of the cam 42 so as to move the arm 36 to slide the plate 33 to the right, Figure 2, along the shaft 31, this movement, or course, taking place simultaneously at opposite ends of the machine. By this movementthe pins 43 are withdrawn from engagement with the paper, a stripper plate T8 being mounted on the end of the shaft 31 so as to insure stripping the paper from the pins. By this time the paper has reached the position shown in Figure 8 in front of the ejector plate 51 which is pivoted on one of the brace-rod 5 and held in retracted position by the spring 50. This plate extends along the entire length of the paper, being provided with a central notch 7 9 to provide room for the arm 62 and its mechanism and extends far enough to engage a pair of arms mounted on the shaft 23. The arms 80 come into engagement with the plate 51 at this point of the cycle so as to move that plate to the left, Figure 8, to eject the rolled paper from the machine as illustrated in ig'ure 9.

iits'wn 0/ operations.

The papers are stacked upon the tray 8 in a swayed stack with the folded edges down and are held in place by the catch 12} which engages the lower edge of the first paper. The movement of the hopper 1 causes the plate 15 thereof to depress the catch 13 to allow the first paper to enter the hopper, the edge 18 of the stop 16 being thrown into the path of the succeeding paper by pressure on the tail 19 by the paper being ted. The papers are thus individually led from the bottom of the stack. The paper being fed moves to the position shown in Figure 5 and is held in that position until the pins 43 move out of engagement with the arm 29 so as to allow the hopper 14 to he moved to delivery position as shown in Figure 4 by the spring 50. At the same time the paper being operated upon by the pins 43 is moved out of the way of succeeding pape-rs. The movement of the hopper 14 to the position shown in Figure 4 allows the paper to drop into the crotch 24. The paper is held in this position until one of the pins 43 passes the lower edge thereof as shown in Figure 4, so as to embrace the paper between the pins. As the movement progrosses, the arm 49 is again released by the pins 43 whereupon the hopper moves to receiving position as shown in Figure 5, and the paper drops down to the plate 44.

The paper is now engaged by the pins 43 7 intermediate its edges and nearer to one edge and is rolled against the plate 44. It will be noted that the pins engage the pa per nearer to the loose edges than to the folded edge so that when the rolling operation is completed, the loose edges will be completely enclosed and onlythe folded edge exposed.

At the completion of the rolling operation the paper is delivererto the bight of the tie wire, said wire being held in proper position therefor by depression of the arm 46 as previously described. The paper is carried into the higl'it oi? the tie which is looped tl'ierearound, the two ends being caught in a twisting mechanism, previously described, and the ends twisted together to secure the tie.

The paper is now brought opposite the ejector plate 51 after which the arms 80 move this plate outward to eject the paper from the machine.

It will, therefore, be seen that this invention accomplishes its objects. A device is provided which is adapted to roll a paper with the loose edges in and only the folded e ge exposed. The papers are fed individually to the machine from the bottom of a. swayed stack. They are engaged by a for]; formed by the pins 43, rolled and delivered to the bight of the tie which is then secured and the paper is ejected.

It is obvious that various changes may be made in details of construction without departing from the spirit of this invention; it is, therefore. to be understood that this invention is not to be limited to the specific details shown and. described.
