PAPER-ROLLING- MACHINE.

Application filed March 7, 1922. Serial No. 541,846.

To all whom it may concern:

Be it known that I, DAVID W. Henson, a citizen of the United States, residing at Green Bay, county of Brown, and State of Wisconsin, have invented new and useful Improvements in Paper-Rolling Machines, of which the following is a specification.

This invention relates to improvementsin paper rolling machines of the type adapted to be used in winding toilet paper, paper towels, wrapping paper, etc, upon suitable cores.

It is the object of this invention, to provide a machine whereby the operator will be enabled to wind paper rolls more speedily than has heretofore been possible. As will hereinafter be explained, a machine embodying this invention winds paper at high speed in a substantially continuous operation, the transfer from one roll to the next being accomplished without an appreciable loss of time. p

It is more particularly the object of this invention to provide in a paper winding ma chine a multiple spindle device having means for turning the head and tail stocks simultaneously to bring any spindle into operative position, and an improved centering and clutching device adapted to facilitate the substitution in driving position of each spindle successively.

Further objects of this invention are to provide a simple and eificacious machine semi-automatic in its action whereby the clutch, after having been disengaged from one spindle, cannot be moved to operative position again until the succeeding spindle is centered therewith; and to provide such a machine designed, particularly as to the controlling devices, for the maximum possible convenience of the operator.

In the drawings:

Figure 1 is a side elevation of a machine embodying this invention and adapted for use in forming rolls of toilet paper.

Figure 2 is a plan view of the same.

Figure 3 is a detail view of that portion of the machine with which this invention is immediately concerned, as viewed along the line of sight indicated by the arrow in Figure 1.

Figure 4 is an elevation of the head stock. Figure 5 is a plan of the same. Figure 6 is an elevation of the tail stock. Figure 7 is a plan of the same.

Like parts are identified by the same reference characters thruout the several views.

The machine frame 1 carries at its rear a set of brackets 2 which are provided at 3 with open journals for the reception of the trunnions 4 of the supply or parent roll 5. The lead of paper from the roll 5 is passed over the matrix roller 6 and maintained taut thereon by the pressure of clamping rollers 7 and 8, while perforating blades 9 carried by the star wheel 10 are successively driven thru the paper into registry with suitable matrices in roller 6. The several elements above noted are driven in co-ordination by suitable gearing from a power shaft 12. A roller 13, likewise power driven, rests against a. block 14 constituting a retarding device which efiectually prevents the apfiearance of any slack in the winding rolls.

oller 13 is mounted in a frame so connected to handle 15 as to be raisable by the operation of said handle to relieve the pressure and tension on the paper upon occasion.

The roll winding device proper is disposed upon a sub-frame including a pair of forwardly projecting arms 16 attached to the main frame 1 as shown in Figure 1.

In the forwardly projecting arms 16 is journalled a shaft 17 to which are secured the head stock 18 and the tail stock 19. The head stock 18 comprises a disk'which bears upon its periphery suitable journals 20 for a number of live spindles .21. The tail stock, as is best illustrated in Figures 6 and 7, is preferably constructed in the form of a spider, the arms of which carry suitable dead spindles 22. Each dead spindle is maintained in registry with one of the live spindles of the head stock by reason of the fact that the head and tail stocks are keyed to the same shaft. The head and tail stocks, being mounted for rotation with shaft 17 and being fast thereto, are adapted to be turned as a unit to bring any of the live spindles 21 into an operative driven relation to the driving means hereinafter to be described. A hand wheel 23, integral with the tail stock 19, is preferably provided to facilitate the manipulation of the head and tail stock, to bring the live spindles successively into operative position.

An extension 24 of the arm 16, which supports head stock 18, has provision for a bearing 25 for the axially movable rod or pin 26, and also carries a bearing sleeve 27 spring pressed pins 35 by which resilient within which the tubular power shaft-28 is 2. A knurled nut 34 is threaded uponthe exterior of the bearing sleeve 27 and carries,

pressure can be exerted .thru a ball floated disk 36 upon the face of pulley 31 opposite to that, which bears against the leather faced disk 29. By this means an adjustable and resilient pressure can be exertedupon saidiof the end of the rod'into the opening pulley'determinative of the torque which will be imparted frictionall by said pulley to the tubular shaft 28 t ru the leather faced disk 29.

At the inner end of the tubular shaft "28is a clutch member 38 which may be conveniently constructed in the form of. a flat plate so mounted as to be slidable axlally with res ect to said tubular shaft while connected or rotation therewith. A shaft 39 extends thru the center of shaft 28 and is provided at its inner end with a head por-.

.tion 40 which is operatively connected to .the plate 38 above referred to. A spring" 41 confined between a shoulder of the tubular shaft 28 and the head 40 upon shaft 39 tends to force said head and the plate like clutch membercarried thereby inwardly toward the operative position of engagement of said clutch.

-Each of the spindles 21 is provided u on its outer face with one or more note es lowed to be forced by spring 41 into its operative ositionas shown in Figure 3.

A clutc operating lever 45 is provlded with a fulcrum at 46 and is pivoted at 47 to a rod 48 which is disposed axially within the tubular shaft 17 upon which the head and tail stocks are mounted, as is clearly shown in Figure 3. The rod 48 is provided with an extended hearing within shaft 17 and passes entirely thru said shaft. At its end, rod 48 carries a shifting arm 49 which is rigidly connected to said rod and to the rod 26, which is journalled at 25 in the supporting arm 16. The end of the shifting arm 49 is forked at 50 or is otherwise loosely engaged within a collar 51- carried by the end of the axially movable clutch operating shaft 39. It will be clear that when the handle 45 is moved to the left (as viewed in Figure 3) the rod 26 and the shaft 39 will also move to the left, retracting the clutch member 38. A spring 52 hearing against one of the supports 16 serves to return handle 35 to its normal position when the'grasp of the operator is released.

Attention is directed to Figure 4. It will end of said rod are preferab be noted that the head stock 18 is provided with a number of openings 53 each of which is disposed in predetermined relationship to one of the live spindles 21. The arran ement is such that when a given live spin e 21is: in exact alinement with the driving shaft 28 the correspondin opening 53 will register with the end of 518 longitudinally slidable rod 26. The opening 3 and the tapered to facilitate the exact alinement of the drive shaft. and live spindle following the entry It is particularly to be noted that the arrangement is such that as} long as rod 26 is not inserted in one ofthe openin s 53, the

shifting arm 49 to which rod 26 is rigidly attached ill maintain the clutch member 38 out. of operative position where it can in no wise interfere with the rotative move- 'ment of the head and tail stocks for the purpose of positioning a new live spindle for rotation.

The dead s indles 22 are provided at their inner on with openings for the reception of the reduced end' 55 of a mandrel 56. A ball bearing 57 may be provided within each dead spindle to permit the free rotation of the mandrel therein. To facilitate the insertion and withdrawal of the mandrels, the dead spindles 22 are preferably so constructed as to be lon 'tudinally movable within the tail stock. prings 58 normally press each. spindle inwardly. and the heads of bolts 59 are adapted to contact with cover plates 60to limit the extent of ossible. inward motion. 3

ach live spindle 21' is provided at its inner end with a square sided .recess 61 adapted to enga e the squared ends 62 of the mandrels 56. t will be'obvious thatthe operator will be able to manipulate each mandrel 56 into position very readily-by first insertin its rounded end 55 into the hearing within the dead spindle 22 and forcing said dead spindle outwardly to a suflicient extent to permit the introduction of the squared end 62 of the mandrel into the opening in live spindle 21 designed to receive it. The spring .58, exerting acontinuous inward pressure. upon the dead spindle, will hold the mandrel in position until it is released by the operator. 1

Carried by the machine frame '1 below the arm 16 is a semi-cylindrical glue pot 65 within which is disposed a roller 66 mounted upon spring supported bearings 67. This roller lies in the path of card board tubes carried by mandrels 56 upon which the paper is to be wound. When the head and tail stocks are rotated each of the tubes will in turn be brought into contact with the roller, which will deposit'glue upon the exterior surface of the-tubes.

Upon the machine frame best shown in Figures 1 and 2, is a transverse shaft rotatable by a handle 71. A wheel 72 fast to the shaft carries a metallic ribbon 73 to which is attached a spring 74 tending to hold lever 71 in the raised )osition shown An arm 75 which is made ast to shaft 70 carries at its end a block 76 adapted to be moved by handle 71 to bring the strip of paper coming from the parent roll 5 into contact with the freshly glued surface of the properly positioned card board tube upon which the paper is to be wound.

The operation of this machine is as follows: I

The paper strip unwound from the parent roll 5 is passed thru the various perforating and tensioning devices in the manner already described and is engaged with the freshly glued surface of a suitable card board tube carried by a mandrel 56 in the position designated by the letter A in Figures 1, 2 and 3. The lever 45 is now released to allow clutch member 38 to move into operative driving relation to the designated live spindle 21 whereupon the strip of perforated paper passing thru the machine is wound upon its card board tube.

When the roll of paper has reached its proper size the operator grasps lever 45 and moves it to his left to disengage the clutch and release the rotatable head and tail stocks from the positioning pin or rod 26. The operator can now utilize the hand wheel 23 upon the tail stock to turn the head and tail stocks simultaneously counter clock wise, as viewed in Figure 1. At the first movement of handle 23 he may release lever 45; and the positioning pin 26, sliding upon the outer surface of the disk-like head stock 18, will retain clutch member 38 in inoperative position.

When hand wheel 23 has been sufficiently rotated to bring the newly wound roll of paper to the position indicated at B, a freshly glued cardboard tube will have come to position A with its supported mandrel and live spindle in alinement with the drive shaft 28. At this point the positioning pin 26 will come into registry with the tapered opening 53 and will enter said opening allowing the clutch member 38 to engage the jaw 42 of the given live spindle 21. Any shock resulting from the sudden engagement of the clutch will be absorbed by the slipping of pulley 31 relative to the leather faced disk 29, the amount of such slippage being adjustable by means of nut 34.

In'Figures 1 and 2, the operation above described has just taken place. It will be noted that a freshly glued cardboard tube ppears at A and a full roll is shown at B. he strip of paper with which the full roll has been wound has not yet been broken. To start the new roll it is only necessary for the operator to pull handle 71 into the position in which it appears in these drawings. The block 76 is thereby lowered and brings the paper strip into contact with the glued surface of the rotating tube at A. The paper strip immediately becomes fast upon the tube and begins to wind thereon, severing itself from the roll previously formed. The full roll may be held against a possible unwinding by the operator.

It will be noted that during the time re- (iuired for the winding of a roll in position 1 the operator will have time to remove the full roll from position B and to insert in its place upon the mandrel in such position a fresh card board tube. With each movement of the head and tail stocks a full roll is brought to the position for removal by the operator, a fresh cardboard tube is carried to the device which covers its surface with glue, and a freshly glued tube is brought to the operative driven position where paper is wound thereon.

It is desired to emphasize the fact that the controlling devices and particularly the ar rangement whereby the clutch is held inoperative until the live spindle is alined with the power shaft greatly facilitate the operation of a machine of this kind. The operator, having thrown out the clutch and started to turn the head and tail stocks is enabled to forget the clutch knowing that it will be automatically re-engaged at the proper time. There is, therefore, no need to move any lever twice in a given sequence of operations and the care of the machine is thereby so simplified as to enable the work to be done at comparatively high speed.
