REEL on WINDING-MACHINE.

To all whom it may concern Be it known that I, ANTON Skorsnnn, a citizen of the United States, residing at Chiin the county of Cook andl State of Illinois, ful Improvements in Reels or Winding-Machines, of which the following is a specification.

This invention relates to machines for winding upV paper, cloth or otherl fabric or material, and more particularly to such machines which will automatically wind up and cut off small rolls lfroni a continuous strip of material.

Among the objects of these machines are to provide means whereby "the" materlal which is being wound will be accurately measured, regardles of the thickness of the material, so that each ofv the small rolls will contain as nearly as possible the exact de--` sired amount; to provide means whereby the feed of the machines they material which is/being agted upon so that if the material is torn or broken, it will stop the further winding action. chine; and furthermore .to providev such novel'features ofconstruction and improvements in details as will be more fully described and pointed out hereinafter.

The'reeling or winding up of wall paper into small rolls illustrates oneof the uses to which this machine is adapted. In the usual manufacture of Wall .paper the paper from the -drying racks yis wound into large rolls and then the paper in these large rolls is unwound and wound up into small rolls by means of manually operated spinjdles. The paper passes through' the print- 'ing machine at such a high rate of speed that v1t requiresan exceedingly rapid machine to take the paper kfrom the drying racks and automatically roll it into small rolls, and so farI jam aware no machine has been produc which can be operated' sufficiently rapid to do this work with the exception of certain machines heretofore patented by me.

l, The present `machine is adapted to be o erated at a high rate of speed so as to ta e the paper directly from the drying rack and wind( it into the desired size of rolls.

In the accompanying drawings illustrating my invention; Figure 1 represents a front elevation of the lower part of the machine, that is thesides-fromwhich the rolls are discharged,lparts being omitted or bro-A ken away for convenience in illustration;

have invented certain new and usewill Vbe operated byin my prior Patents Patented Nov. 14, 1916.

Application filed July 29, 1912. Seri-a1 No. 712,026.

Fig. 2 is a detail showing the lever Y.for operating the machine; Fig. 3 is arear elevation with parts also omitted or broken away for convenience 1n illustration; Fig. 4 is an end view also with parts omitted .or broken for the measuring device; Fig. 6' is at detail cfa portion of the measuring and cut-off operating mechanism; Fig. 7 is a sectional view taken on line 7, 7 of Fig. 6; Fig. 8 is a sectional view taken onmthe line 8, 8 of 6; Fig. 9 is a plan view of a portion of the apparatus shown in Fig. 6; Figs. 10 and l11 are details of portions of the driving mecha-` nism for operating the spindles and cutting ,0E devices,"and Fig. 12 is a detail of the dis` charge device.

As indicated Vin these drawings, 15 representsv a frame work 0f suitable design for supporting the various parts, which frame work is provided with suitablebearings for d riven in any desired-manner, for instance, by means of a gear 17 which vmeshes with apinion 18 on a vertical shaft 19. rIlhe lower end of the shaft 19 is provided with a gear 20 which meshes with a gear 21 on a countershaft 22. The gear 21 also meshes with a gear 23 on a shaft'24 which is-substantially in alinement with -the yshaft 19. The'shaft 24 is provided with a gear 25 which meshes with a gear 26 on the driving shaft of a motor 27. The shaft 16 is connected through trains of gearsv with the winding spindles, which spindles are substantially the same in construction and operate in a similar manner as the spindles shown shown in such patents are These spindles, as

thefabric and when they forked to receive are moved inwardly for engagement therewith, clutches are thrown into operation which cause the spindles to rotate until the. roll is completed, then as withdrawn to release the roll, the clutches are thrown out which causesthe spindles to stoprotation. In the present instance the shaft 16 is-vprovided at one end with a gear 28 whichy meshes with a gear 29 on a coun-' tersha'ft 30. rI he gear 28 is free upon the` shaft 16 but is adapted to be driven byv means of a clutch 31 which is adapted to be pressed into engaging position by means of a `spring 32 which is acted upon by a yoke or slide 33' on a shift bar 34. The bar 34 is longitudinally movable in its bearings in the the spindles arel away; Fig. 5 is a detail of'the adjustment NOS. 952,282 and 992,692.

frame and is connected at one end with a lever (best seen in Fig. 2) which lever is pivoted to a bracket 36 from the frame and which is provided with a detent 37 which` engages with the toothed segment 38 for holding the lever in adjusted position. Variable speed for the shaft 30 is provided by having a second gear 39 mounted on the shaft 16 which gear is of different diameter from the gear 28 and which meshes with a gear 40 on the shaft 30. The gear 39 is also loosely mounted 0n the shaft 16 and is driven by means of a clutch 41 which is pressed into engaging position by means of ,turns one of the spindles 45. At the other end of the shaft 30 is another gear 46 which is of the same size as the gear 40 and which meshes with a second gear 43 on the clutch member 44 .for the second spindle. It will thus be seen that by means of this arrangement the speed of rotation of the spindles may be varied but the speed of the shaft 16 remains constant. ciprocating the spindles 45 is closely associated with the feeding and measuring mechanism which will now be described. The strip of paper or fabric such `as indicated at 47 in Fig. 4, passes in between two rollers 48 and 49 atthe top of the machine and then down into position to be engaged by the spindles. The roller 49 is mounted on a shaft 50 in fixed bearings in the frame, while the roller 48 is mounted in adjustable bearings 51 which are pressed downwardly by means of springs 52, the pressure of which may be adjusted by means of the nuts 53 so as lto give any desired pressure between the rollers. The shaft .50 is provided at one end with a gear 54 which meshes with a gear 55 on a shaft 56,'which shaft is provided at the opposite end with a lisk 57, having an adjustable crank pin 58' (mounted thereon. A convenient form for such adjustment is clearly shown in Figs. 4 and 5, the pin being shown mounted in a. 'slot 59 in the disk'57 and having its inner end engaging with a screw whereby the distance of the pin from the center can be accurately adjusted yto vary the throw of the crank.

A crank rod .61 connects from the pin.58 to one end of a lever 62 which is pivoted at 63 to the frame and which carries an adjustable counterweight 64 at its opposite end,v

Lacasse? The mechanism for rekeyed to\ the shaft so that it such counterweight being for the purpose of balancing the weight of the crank rod and other connected parts. The lever 62 is connected by means of a link,65 to a rod 66 which rod moves in suitable guides in the frame and is connected at its lower end with a. link 67 which in turn is connected with one end of a bell crank 68, best seen in Figs. 4 4and 6. The bell crank 68 is pivoted on a shaft69 in a casing 7 0 mounted in the lower part of the frame. A ratchetwheel 71 is rigidly mounted 011 the shaft 69 and is turned by means of a spring pressed pawl .72 mounted on the other arm of the bell crank 68. A second spring ressedpawl 73 is mounted on the casing 0 and enga-ges vvwith the ratchet wheel 71 to prevent its'` backward movement. The shaft 69 also carries a cam 74 which is rigidly secured thereon. The cam 74 engages with a wheel 75 on a piston 76 in a cylinder 77 formed integrally with the casing 70 and presses this piston out against the tension of a spring 78 Whi-ch is adj ustably held in position by mgns of a threaded cap 79. In order that the pi may have a quick return under the inlluence of the spring 78 a projection 80 is provided which extends from the piston., 76 slightly beyond the wheel 75, so that. it will. remain in engagement with the cam momentarily after the high part of the cam has left the wheel andwill then drop or move into the low part of the cam as shown in Fig. 6. The' piston 76 is adjustably connected with a bar 81 which reciprocates in suitable bearings on the main frame and which carries a tappet 82 which is pivoted at'its outer end. This tappet is held in normal position by means of a spring 83 and the movement thereof, in either direction is-limited by shoulders or stops on\ he bar 81. The tappet 82 is adapted toen a e with an arm or' projection 84 on a locking lever 85, which lever is pivoted at 86 to a cylinder or casing 87`which is secured to the frame. This spring 91. As shown in Fig. 6, the' piston 90 is normally pressed toward the left by means of a spring 92. This tends to throw the clutch 93 into operative positim. This 4 lever is adapted to lock one of the operating.

clutch may be of' any ordLI/iary or preferred.'VA

farm, but as shown, t cone .member 94 is'rv connected with the/ iston 90 whichts over the shaft 22 and such epee memberis will be driven thereby. `\The cup member 95 bf the clutch is connected directly with the gear 96 which meshes with a gear 97 on a short countershaft 98 which runs at right angles tothe shaft 22 and which is mounted in suitable bearings in the fra-me. The shaft 98 is provided with a gear 99 which meshes with a gear 100 of the same size, which gear drives a second shaft 101 which is mounted adjacent to the shaft 98 as clearly shown in Fig. 10. These shafts are provided with right and left worms 102 and 103, the worm 102 being of twice the pitch as the worm 103. The worm 102 meshes with a worm gear 104 which is loosely mounted on a shaftl 105, having its bearings in the frame. The worm 103 meshes with the worm gear 106 which is also loosely mounted on the shaft 105 and which moves at half the speed of the gear 104. A face cam 107 is'secured to, or formed integrally with, the worm gear 106 and engages with a pin or projection 108 on a piston or slide 109 which is slidably mounted in the hub of the worm gear 104.

toward the cam by means of a spring 110.

A rod or pin 111 is slidably mounted 'within a tubular projection on the piston 109, this rod being held in normal position by means of a spring 112. The outer end of the 'rod 111 is adapted to engage at times with a driving lug or projection 113 on a disk or wheel 114 which is securely mounted on the shaft 105 and which is adapted to turn such shaft. The rfforin gear 106 is also provided with a 'trip finger or projection 115 (shown in Fig. 8) which is adapted to coact with certain parts to throw the clutch 93 out of engagement. This iinger or projection engages with the end of a lever 116 which is pivoted at 117 the frame and which is provided at one side with a face cam 118'. This cam engages with a. roller 119 on the end of a bar 120 'which bar connects between parallel links 12.1 and 122, these links being pivoted at their upper ends to suitable hear-v ings on a rod 123, which rod is securely fas-- tened in the frame. The lower end of the link 122 is provided with pins or trunnions 124 which pass throughslots in the sides of the cylinder 87 and engage with the piston 90. This arrangement is suchl that when the ycam or finger-115 strikes the free end of the -This pin or projection is normally pressed lever 116, it raises the lever land causes theface cam 118 to press against the roller 119 which swings the bar 120 to the right as shown in Fig. -.6 and moves the piston 90 a sufficient distance to withdraw the cone 94 from the cup 95 and `,to permit the catch 88 to engage with the projection 89, which holds the clutch out of engagement. i

AramVv or projection 125 is secured to the disk 114 (Figs 1-1 and 12) whichengages attimes with the end of a bar 126 which bar' is carried by links 127 and 128 pivoted tol stationary portions of the frame. 'A discharge nger 129 is connected with the link 128, and a spring 130 is connected from this link to a stationary part of the machine for roll and discharge the same. Then as soon asr the cam 125 has passed beyond the bar 126`the spring 130 returns the parts to normal position. A double cam.131 is secured which is pivotedat 133 to the bottom of the frame. One side of this cam engages with to the shaft 105 and operates a lever 132 a roller 134 secured to the lever, while the v other side engages with a flat projection 135 which permits a quick drop of the lever after the roller has passed from its portion of the cam. The upper end of the lever 132 is connected to a link 136 which is pivoted to an arm 137 on a rocker bar 138, the ends of this bar being pivoted in suitable bearings in the frame. This rocker bar'is provided with arms 139 which are connected by means of links 140 with downwardly projecting arnisv141- on rocker sleeves 142 which are' pivoted on the main Supports for the spindles. The arm 141 is also connected by means of a. link 143 to a slide 144 which ca'rries one of the cuttingp' knives 145. The rocker sleeves 142 are also provided with upwardly extending arms or connections 146 which are connected bv vmeans of links 147 to a second slide 148 which carries the other cutting-off knife 149. This arrangement is such that the cani 131 will swing the lever v 132 to the right as shown in Fig. 4 which separates the cutting-0E knives. As soon as the projection 135 passes the high part of the cam, a spring 150, which connects from the arm 137 to a stationary part of the frame, moves this arm to the left and swings the rocker bar 138. The connecting parts cause thesleeves 142 to be rotated which in turn draws the lmives 145 and 149 together to cut off 'the material after the Iroll has dropped.

. Theshaft is provided-at either end with 'cam wheels 151 which engage with rollers 152 on the ends of the bars 153.

These bars are lpivoted to links 154 and 155 thel upper ends of the levers 155 will swing l outwardly as indicated in Fig. 1, .whichwillwithdraw the spindles 45 from the completed roll and will then move inwardly to cause the spindles to again engage with the fabric.

-sired speed for the spindles.

The operation of the machine is as follows: The paper or other fabric to be reeled is passed between the rollers 48 and 49 as shown in Fig. 4, and down through the slots in the spindles 45. Then the lever 35 (Fig.

2) .is shifted from neutral' position, either tween the rollers 48 and 49, the latter being vso preferably made of suitable material 'or provided with a suitable covering, such as rubber, so as to insure these rollers being positively turned with the same peripheral speed, as the speed of the fabric passing thereover. This is, in fact, the measuring roller and directly controls the cutting-oil action. As the roller 49 revolves, it turns the shaft 56 which turns the disk 57 with the adjustable crank thereon. As Athis crank is turned it reciprocates the rods which connect it with the bell crank 68 and causes this crank to be swung on its pivot. The movement of the crank causes the pawl 72 to rotate the ratchet wheel 71, which in turn drives the cam 74 in the direction indicated in Fig. 6. This cam gradually presses against the roller 75 and vmoves the piston 7 6 to the right against the tension of the spring 7 8 until the tappet 82 passes beyond the linger or projection 84 on vthe lever 85. As the high part of the cam 74 'is reached it engages with the projection 80 so that when it passes the'projectiom the spring 78 will quickly force the piston 76 back to original position. This causes the tappet 82 to strike against the projection 84 which raises the outer end of the lever 85 until the catch 88 releases the piston 90. This permits the spring 92 to quickly force the clutch 95 into operation. This clutch then drives the shaft 98 (Fig. 10) through the gears 96 and 97 and this in turn drives the shaft 101 through the gears 99 and 100. This causes the worms 102 and 103 to drive the worm gears 104 and 106. As the gear 104 moves at twice the speed of the gear 106` the pin 108 engages with the face cam 107 and forces the piston 109 to the left as shown in Fig. 11, which causes the pin 111 to engage with the driving lock or projection 113 on the disk 114. If such pin moves toward' the left at the time it isY opposite the Projection, the spring 112 permits the piston to be moved until the pin 111 passes the projection when the spring 112 will force the pin into position to engage with the side of the lock 113. This causes the sha-ft 105 to be driven, which turns the cam wheels 151 and this swings the arms 155 out, thereby withdrawing the spindles from the completed roll. As soon as the spindles are free from the roll the discharge fingers 129 are swung downwardly through the action of the cam 125, thereby causing the roll to quickly drop onto the discharge chute 157 (Fig. 4).. In some instances these discharge fingers may not be necessary as the roll will drop through the action of gravity, although they may be desirable when the machine is operated at a high speed. As soon as the roll drops, the double cam 131 releases the lever 132 so that the spring 150 may actuate the cutting olf knives which are caused to coact and cut oft1 the fabric just below the spindles. Such paper or fabric is preferably held by means of guides suchv as shown in my former patents. v

As soon as the completed roll drops and the paper or fabric is severed, the levers 155 again move inwardly to cause the forked spindles to again engage with the paper or fabric preparatory to winding the next roll. At about the time the spindles return to operative position and start to wind the next roll the cam or projection 115 raises the end of the lever 116 which acts through the connecting'parts to throw the clutch 95 out of engagement. which places the parts again in substantially the same position as when starting. It will thus be seen that substantially the whole machine, with the exception of the spindles, is directly operated or controlled by the fabric passing over the roller 49.- In other words the time required for one revolution of the cam 74 which actuates the discharge in cut-off mechanism is directly dependent upon the Vnumber of turns of the roller 49, and by adjusting the crank pin 58 the throw ofthe pawl 72 maybe regulated `so that the cam will make a complete revolution when the roller 49 has made any desired number of turns. 'It will thus be seen that this provides an exceedingly ace irate measure for measuring the amount of paper or fabric in each roll, andthe amount to be placed in each roll may be readily varied within the limits of the adjustment of the machine. As the operation of the stopping, cut-od' and discharge mechanism depends upon the papel' or fabric which is being rolled, it is often desirable thatV these parts shall operateas easily as possible and without putting any undue load on the roller 49 so that the weight 64 which serves to balance the rods and other parts connected with the adjustable crank is a desirable feature as it relieves Y the paper of a certain amount of strain.

The operation of the machine by means of the fabric, which is being wound into rolls also serves another exceedingly useful the paper or fabricvby its turning the roller 4.9 gives'substantiallyan absolutely accurate lineal measurement, regardless of the thicknessof thel paper or fabric whichis being acted upon.
