The machine in general comprises winding mechanism, means for automatically feeding spindles for the paper successively to said winding mechanism, means for autom'aticallyapplyingpaste to; said spindles as they pass to said winding mechanism, mechanism for controlling the extent of the winding of the paper by the winding mechanism on the spindles from a paper supply roll, this .control mechanism acting to operate a cutter to sever the wound-up paper from'the incoming sheet, thismechanism also acting in conjunction'with the wound-up roll of paper to control an ejector by which the finished roll of paper is moved to position for delivery fromthe machine.

Referring first to Fig. 1, the numeral 15 designates the incoming end of a sheet of paper from a paper supply roll, the same passing over guide rollers 16 and 17 suitably journalled in the framework 18 of the machine, thence over a roll 19 mounted on a rotatable shaft 20, thence over a winding roll 21 driven through a shaft'22 and cooperating with a companion winding roll 23 which is free to be rotated under the action of the spindle and the paper being wound up thereon.

Each spindle comprises a mandrel 24 usually of metal and a winding core 25 that may be of either metal, paper or other suitable material and in most instances is paper.. The. empty spindles are deposited in a magazine .26 formed of suitably' braced angle frame or track members 27 upon which the outer ends of the spindles are free to roll, the magazine'being inclined to permit the spindles to feed by gravity along the tracks formed, by the angle members 27 to a position for their delivery into the winding zone which is between the rolls 23 and 21, one of the spindles being shown in a position for the commencement of the winding operation. The shaft 22 rotates continuously and carries a sprocket 28 connected by a chain29 to a sprocket 30 mounted to revolve on a fixed shaft 31 and pinned to a clutch drum 32 as shown in Fig. 6, this drum rotating continuously and through a control'hereinafter described, the drum 32 is adapted to be connected in driving relation with a cam 33 also rotatable on the shaft 31. This cam 33 as shown in Fig. 2 is engaged by a roller 34 carried by a link 35 connected by a pivot pin 36 to a block 37 secured to one of a pair of spaced lever members 38 pivoted on a shaft 39 carried by the framework of the machine, said lever members 38 being connected together by a transverse tie member '79. These lever members 38 thus receive motion under conditions herein-' after described from the cam 33, and their outer end portions 40 are: bent downwardly and carry a shaft 40 on which a roller 41 gs mounted and adapted to engage the paper as it is rolled up on the spindle, then presented to the winding mechanism. Thus the levers 38 receivemotion both from the paper being wound and the control cam 33.

Referring to Figs. 1, 8 and 11, the foremost spindle in the magazine is adapted to be engaged at its outer ends by spaced gate or stile wheels 42 mounted on a shaft 48 extended above and across the magazine and carrying a ratchet wheel 44 engaged by a pawl 45, pivoted at 46, and held in 013-- erative posiiion by a spring 47, it being noted that the release of this pawl will, through the weight of the spindles in the magazine, cause the stile wheels 42 to rotate and thus through the control of the pawl 45 allow the lowermost spindle in the magazine to be released therefrom and proceed down the trough or tracks 27 to a windingposition.

Control of the pawl 45 is effected through a release pawl 48, pivotally mounted at 49 011 a bracket 50, secured to the block 37, and normally urged against a stop pin 51 by a spring 52, the free end of the pawl 48 acting under the control of the link 85 and levers 38, after these parts have reached an upper position, to engage the free end of the pawl 45 on the downward movement of these parts to release said pawl 45 from the ratchet 44 and permit said ratchet to turn one tooth and thus release a single spindle, this ac tion taking place at a time when the winding mechanism will be in a condition to operate on the newly released spindle.

In order to hold the initial windings of paper on the spindle, means have been provided to apply pasie to the spindle on its way to the winding mechanism. Referring to Figs. 8 and 11 of the'drawings, it will be noted that there is a roller engaging finger 53 on a shaft 54 extending across the magazine below the gatewheels 42, said shaft having a crank arm 55 at one end, limited in one position by a stop pin 56 and engageable with a crank arm 57 mounted on a paste arm shaft 58 and held in engagement with the arm 55 by means of a spring 59. The shaft 58 has arms 60 securedthereto and carrying a paste applying bar 61 adapted to'be moved by the arms into a paste tank 62, disposed below the spindle tracks 27, with the paste bar 61 disposed in ihe path of movement of the spindles so that when a spindle, re-

leased by the gates 42, passes over the finger 53,

' its weight will depress the same and thereby swing the 55 toward the left thus moving the shaft 58 through the movement of the arm 57 by the arm 55 so as to dip the paste bar 61 in the paste tank and as spindle leaves the finger 53, the paste bar 61 will be raised 'up against the spindle as it passes by through the action of the spring 59 on the arm 57 of the paste applying mechanism justdescribed so that the core 25 of the spindle has paste applied thereto over a certain portion of its area and is delivered in this condition to the feeding zone.

When a spindle is in a feeding position, its

pasted portion comes into contact with the end 68 of the paper 15 coming from the supply roll and thereby becomes pasted to this end of the paper and at this time the winding of the paper on'the-spindle also commences since the weight of the spindle is such as to cause the'pa'per. 15 to be fed between it and the rotating roL 21 and consequently the paper is fed intothe machine Y at the same time the spindle is. revolved and in tained which is determined by mechanism hereinafter described that controls the cutting mechanisrn. As the paper winds up, the arms 40 of the levers 38 are raised and in raising, they in turn operate the ejecting mechanism, which when the desired amount of paper is wound on the roll, allows the finished roll to roll off of it and down onto the spaced guides of a delivery trough 64. This ejector mechanism comprises spaced ejector members 65 having feet 66 with inturned spindle engaging ends 67 as seen in Figs. 8 and 10. These ejector members are vertically slidably mounted in a frame member 68 carried on upright posts 69 secured to the main side frame 18 of the machine. This frame member 68 has spaced stops 71 and 72 secured to it. These spaced stops ccoperate with a stop pawl or lever 73 pivotally mounted at 74 on'an arm 75 of a dog member 76 secured to the upper end of each ejector member 65. Each stop member '71 is formed as a side projection of a channel bar 77 and each channel bar '77 forms a seat for a compression spring 78 that acts through the dog '76 to cushion the end portion of the downward stroke of the ejectors 65. The actuating or control levers 38 have a transversely extending bar '79 secured thereto supporting spaced sets of fixed members 80 and 81, each member 81 having a finger 82 cooperating with a latch 83,".slidably mounted in the arms of its companion member 81 and spring pressed outwardly by a spring 84,- to engage the dog 76 and thus raise the dog together with the ejector member 65 operatively connected thereto as the fingers 82 and latches 83 are raised through the upward movement of the levers 88. The latches or levers '73 are urged to latched position by springs 73' and arepivotally ccnnected'at 85 with trip arms 86 adapted to be engaged by the fingers 82 when ineving-downwardly from a raised position, as the dettedline position shown in Fig. 8. These trip members 86 each rest on a supporting stud 87 secured to the companion dog 76. With thisconstruction, when the spindle is in position to start the winding operations, the ejector mechanism is in position shown in full line in Fig. 8 underpushes or raises the levers 38 upwardly, this ac-.

tion also causing a corresponding upward movement of the fingers 82 and latches 88 and consequently a raising movement of the dogs76 and the ejectors 65 secured thereto. finally moves the latches 73 into cooperative relation with the stops 71 when the ejector mechanism is in its extreme upper position as shown in dotted lines in Fig. 8. Under these conditions,

the wound up roll, which has been cut from the web, has been elevated by the feet 66 of the ejector members. to a position where the spindles will readily roll off of the same and down into a delivery trough 64. As the members 38 return This movement downwardly to their initial position, the fingers 2 which have passed their upstroke, engage said levers at the beginning of their dcwnstroke, as shown in the dotted line position of Fig. 8, and act to' push the trip fingers 86 to the left and thereby swing the latches '73 out of locking engagement with the stop 71 by the trip levers 86 on sci-that the ejectors may descend to'their initial position ready toreceive the next spindle.

When the fingers 82 havepassed thetrips 86 on their downward movement, the latches 83 have also passed the dogs 76 due to the beveled face ends of the dogs and the latches which permit the retraction of the latches 8-3- againstthe action of the springs 84 so that the parts again assume the full line position shown in Fig. 8.

The cutting mechanism consists of a relatively fixed knife member 88 here shownin the form of a rod in Fig. 9 clamped to laterally adjustable brackets 89 mounted between the frame members and collars 90 on the posts 69, this rod adapted' to be tensioned through the action of set screws 92 passing through the hubs or collar portions 93 of the brackets 89 and engageable with the posts 69. This rod 88 carries an apron member 94 acting to insure the positioning of the severed end of the paper sheet adjacent the roll for purposes hereinafter described. The movable cutter'consists of a segmentally formed knife bar 95 adapted to slide over the surface of the winding rol1'21 and having side flanges 96 engageable with the ends of said roll and a grooved edge, the upper edge 9'7 of which is a cutting edge, said knife being operated through connecting rods 98, each connected at one end to it and at its other end to lever arm 99 and a shaft 100 .of the measuring control mechanism.

Referring to Figs. 1 to 7 inclusive, the measuring control mechanism includes spaced side frame members 101 secured together and to one of the main frames of the machine by the shaft 31 and liframe bars 102, these parts having shouldered threaded ends and clamping nuts 103 thereon to establish this relation and the shaft 100 which is shown in Fig.4 journalled in one of the frame members '20 and which is similarly journalled in 'the other main side frame member has an extension extending through one of the frame mem-, here 101 and carrying a crank arm 104 operatively connected by a link 105 to one arm of a lever 106 which is pivotally mounted on a pin 107 carried by the actuating link 35 and has an inclined nose'106' adapted to be engaged by a cam mem'- ber 108 secured to the 'cam 33 and movable therewith, so that as said cam 108 makes one revolution, when clutched to the drum 32, the outer end of the lever 106, as viewed in Figs. 1 and 2, will swing downwardly and through link 105, arm 104, shaft 100, swing the arms 99 upwardly and thus through the rods 98 move the cutter knife 95 into cutting relation with the fixed knife 88 and thus sever the sheet as it is being wound up on the roll, it being noted that the sheet in passing to the spindle passes across'the face of the knife or cutting block 88. A spring 104 acts on the arm 104 to return the cutter and its operating mechanism to retracted position.

Attention has been called to the fact that the roll 21 rotates all the time. Consequently, after the paper from the supply roll' is pasted onto the spindle between the Winding'rolls 21 and 23 the paper will continue to wind thereon until cut off by the cutting mechanism above described. Consequently upon the timingof the operation of the cutting mechanism will depend the amount of paper wound up on the spindle and this timing is effected by the time the cams'33 and 108 are rotated by the shaft drum 32 through a clutch connection therewith. Referring to Figs. 2, 4 and 6, this clutch connection includes a clutch pawl 109 pivotally mounted on a stud 110' secured to the side of the cam 33, said pawl having a rear flat face 111 adapted to abut against a corresponding face 112 on the hub of said cam so as to limit its movement in release position and carryinga spring 113 engageable with the hub of the cam tending to move it to clutched position 80 which is effected between said pawl and drum 32 by the cramping engagement of the sides of recess 114 in the pawl with the flange of the drum 32. This movement to clutched'position is controlled by a stop 115 which normally en-' 85 'gages'the pawl 109 to hold it in release position and which is mounted on a shift bar 116 slidably mounted in guide slots in the, frame members 101 and normally held in this position by a spring 116 and a stop pin 117 but which is shifted to release the pawl by the movement of a timing or measuring control member 118 into operative engagement with a stop 119 secured to said bar Referring to Figs. 2 to 6 it will be noted that the control member 118 has its hub 120 siidably' splined-by suitable screws-121 toa keyway 122 in a guide shaft 123 mounted to oscillate in the frame members 101 and that the upperend of said member is recessed and threaded to form a half nut 124 which is adapted to engage or be released from a feed screw shaft 125 journalled in the frame members 101. This screw shaft 125 depends for its rotationupon the feed of the paper from the supply roll to the winding mecha- 10E nism and for this purpose the roll 19 over which the paper passes has a sprocket wheel 126 secured to its shaft 20, as shown in Fig. 1 and is connected by a chain 127 to a sprocket 128 on a stud shaft 129, said sprocket 128 beingcom- 116 pounded with a gear 130 meshing with a gear 131 fixed to the feed shaft 125. From the above it will be apparent thatyas the clutch control member 118 is moved by the rotation of the feed screw 12.5 and moves along the shaft 123 a pro- 115- 7 .jecting finger 132 on said member comes into engagement-with the stop 119 and thereby moves the bar 116 to the left as viewed in Fig. 4, until thest'op '115 movesout from under the pawl 109 to permit the same to be moved to clutched 120:

position. The member 118 normally has its nut portion 124 held in engagement with the shaft 125 bya spring 133 connected at one end to the frame and at the other to a pin arm 1'34 connected to the shaft 123 to which the member 125 118 is keyed, see Fig. 1, and said member is returned, when out of contact with the shaft 125,

by a weight 135, Fig. 5 connected by a'cord 136, Fig. 4, to one of the screws 121.

The measuring of the paper being wound up 13 on the roll is effected by the length of movement 1 of the control member 118 along the screw shaft 125 and this-is controlled by a suitable'means' under the control of the operatorfas shown in Figs. 2, 6 and 7. This means i'ncludesa fixed135 block 137 and a series of manually settable blocks 138, these blocks being mounted betweenspaced guides 139 and140, the blocks 138 each carrying a thumb screw 141 working in a slot 142 in the upper guide 139 and adapted to be clamped against said guide to hold each block in an operative or inoperative position to form a track of Variable length. In order'that the blocks 138 can onlybe moved to inoperative position in successive order, each ofthese blocks has a tongue or stop '143 engageable with the next succeeding block in the series so the first block then in con- :tact with a stop finger 144 on control member 118 has to be pushed back to inoperative position before the next one in series-can be. The guide 139 is grooved at 145 to allow the stop finger 144 to pass along the tops of the blocks when the member 113 is fed forward by the screw 125 until the stop passes the fixed block 137 at which time it comes in contact with a spring finger or cam 146, Figs. 6 and 7, which acts thereon to depress said finger 144 and thus rock the meniber 118 and shaft 123 toward the right as viewed in Fig. 2 and against the tension of the spring 133 to move the nut portion 124 out of engagement with shaft 125 and at the same time tilt finger 144 to a position beneath the lower bevelled faces 147 of the blocks 137 and 138 so that the weight 135 will return the member 118 to its initial position behind the last of the series of blocks 138. When it reaches this position, the spring 133 again swings the control member 118 to an opcrating position. If now the most remote of the blocks 138 shown in Fig. 6 is released fromits operating position and pushed out of the way of the finger 144 it is obvious that the returnfeed of the member 118 will terminate sooner and consequently the forward feed will be shorter so that a shorter interval of time will elapse before the clutch pawl 109 is again operated and that removal of the other blocks 138 in successive or, der will cut down this time until the shortest feed interval is reached which is that across the block 137 that determines the minimum length of pa- :per tobe wound on each spindle for ea h operating cycle of the machine.

Referring to Fig. 2 it will be noted that the roller 34 carried by the link 35 rides on the upper part of the cam 33 and that the lower end 148 of said link is slotted so that said link may be 'reciprocated either by said cam or by the oscillatory movement of the levers 38. After the end of the paper that has been wound up on a spindle is cut from the supply web 15 bylthe knife 95, the

--severed end of the web will be loose on the 'roll '21 and the feed of the paper will be stopped un-- der these conditions, the severed end however being held adjacent theroll 21 by the apron 94 at this time. However, before the next spindle is allowed to assume an operative position be-' tween the winding rolls 21 and 23, it is necessary to bring the severed end 63 of the paper web to a position where it will be engaged by the pasted portion of the next spindle to be delivered to the winding mechanism and for this purpose means have been provided associated with the ejector mechanism for securing the necessary feeding traction of the paperweb against'the roll 21 and this means is shown in Figs. 1 and 16. One of the ejector members 65 has a pawl 149 pivotally mounted at one end 153 to the lower end thereof as shown in Fig. 1 and just before said member 65 reaches its lowermost position, this pawl 149 engages a projection 151 on a pivoted member 152 to swing the same downwardly. This member 152 and a companion member 153, are both pivotally mounted on a pin 154 and a compression spring 155 interposed between them allows relative swinging movement between them and trans mits motion from the member 152 to member 153. The member 153 is connected by a ling 156 to a crank arm 157 on a transversely disposed shaft.

158 journalled in the side frame members of the machine and a series of arms159 are secured at spaced intervals to said shaft 158 and carry paper engagin rollers 160 which are positioned for movement into cooperative relation with the paper and the drum 21 just below the apron 94. Thus when the end of the pawl 149 engages the projection 151 and swings the member 152-downwardly, this motion is transmitted through spring 155, member 153, link'1'56, crank arm 157, shaft 158, arms 159 to swing the rollers 160 on said last named arms into paper feeding position and the severed end 63 is thus fed to a position where it will be pasted'to the spindle delivered to the winding mechanism, the pawl 149 finally tripping past theprojection 151 as shown in Fig. 1 and being limited in its inward release position movement when the members 65 are raised, by a stop pin 161 on the member 152.

The component parts of the machine having been described indetail a brief general operation of the machine will be given. It has been noted that the cam 33 controls the reciprocating movement of the levers 38 to actuate the spindle feed and the ejector mechanism and that the cam 108 associated with the cam 33 controls the cutting mechanism and that the time of actuation of both these cams is controlled bythe measuring mechanism which actuates the clutch which drives the above named cams. Assuming that a spindle has been delivered to the winding mechanism and paper has been wound thereon to such an extent that for the given set position of the blocks 138, the control member 118 has been moved by the screw shaft 125 to a position to engage the stop 119, shift bar 116 and hence allow pawl 109 to engage the drum 32, then the cam 33 is revolved and as it moves from the lower position shown in Fig. 2, it acts through thelink 35 and levers 38 to raise the ejector members 65 from the position they have assumed through the raising of said levers 38.under the action of the paper that has been wound up on the rolland just before the ejector members 65 reach their uppermost position the paper which is then tensioned between the spindle and the roll 21 across the face of the fixed knife 88 is then out by the knife 95 under the action of the cam 108 and directly thereafter the cam 33 lifts the levers 38 to their uppermost position and consequently through the parts 83, 82 and 76 lift the ejector members 65 to their uppermost position and the completed roll of paper is then rolled 02f the ends 67 of the'feet 66 and intothe delivery trough 64. During the upward movement of the levers 38, the pawl 48 snaps by the pawl 45 and as the levers 33' move down under the control of the cam 33, the pawl 48 releases pawl 45 and allows the gate wheels 44 to turn to release a new spindle and at the same time the ejector members 65 move down to a position for the next cycle of operations on this spindle and actuate the rollers 160 to bring the web into position to receive the new spindle with the paste supplied thereto when said spindle takes its position between the winding rolls. After the clutch has been engaged to cause these operations to take place, the control member 118 under the action of the cam 146 and weight 135 has been movedback to release the shifter bar 116 and hence bring it to position to cause stop 115 to release the pawl 109 as the cam 33 completes its-revolution and said control member 118 is thenlcarried back to a point where its finger 144 drops behind the last operatively positioned block 138 to again allow the nut portion 124 of said member 118 to be fed by the screw shaft 125 to a clutch engaging position which occurs as the paper wound up on the last presented spindle between the said spindle and the I rolls 23land 28 reaches the desired length and is ready for cutting off and ejection from the machine. I Y

The extentof travel of the control member .of the blocks 138 will lessen this travel and hence the time between the cutting off and feeding in operations. It will of course be understood that as soon as the spindle is in position between the winding rolls the feed of the paper thereto commences so that while the member 118 ison its return stroke out of contact with the screw shaft 125 a certain amount of paper is being wound onto the spindle.

From the foregoing it will be noted. that I have provided a paper handling apparatus in which the paper web or sheet from a supply roll is automatically fed to the winding mechanism and wound upon a spindle automatically delivered from a magazine to receive it and that when a roll of predetermined length has beenformed, the web is severed and the finished roll is delivered out of the machine.
