JOHN J. WARREN, OF BROWNVILLE, NEW YORK.

MACHINE FOR WINDING PAPER.

Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed March 2, 1905. Serial No. 248,099[

To all whom) it may concern.-

Be it known that I, J OHN J. WARREN, a citizen of the United States, residing at Brownville, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Machines for Winding Paper, of which the following is a specification.

This invention relates to improvements in machines for winding paper designed for use in connection with paper-making machinery, by which the material is made in continuous lengths and wherein the finished paper is received by the winding-machine and by it reduced to compactly-wound rolls of different sizes suitable for commercial use; and the invention relates particularly to improvements in that class of paper-winding machines shown and described in Letters Patent heretofore issued to myself, numbered and dated as follows: No. 631,513, dated August 22, 1899.

The invention further relates to paperwinders of the class known as double-drum winders, and particularly to machines employing two winding-drums of unequal size for the purpose of driving or operating a displaceable receiving-core, which during the" course of the winding of a roll of paper is constantly kept in operative contact with said windingdrums and in which the smaller drum is driven at a higher rate of speed rela tively than the larger drum for the purpose of effecting the uniform, compact, and smooth winding of a roll of paper or like material.

The object of the present invention is to improve the construction and operation of double-drum-winding machines of the class referred to, to provide for greater rapidity, economy, and safety in the operation of such machines, to make certain parts of the device more positive and reliable, and generally to broaden the scope and usefulness of windingmachines of the class.

A prominent feature of this invention as compared with previous devices of the class lies in the substitution of an adjusting-shaft provided with hand-wheels, clutches, and gears in place of the lever, ratchet-wheels, and links formerly employed to increase or decrease the pressure of the receiving-roll upon or against the winding-drums; and the invention further consists in substituting sprocket-wheels and sprocket-chains, the latter being provided with adjustable and flexible parts in place of the plain cables, rollerguides, and weights shown in former inventions.

Another feature of the present invention consists in providing an apron or carrier comprising a band or web of canvas or other suitable material which is disposed on the under side of the large winding-drum. The object of this apron or carrier is to receive the free end of the paper as it comes from the slitter and to carry it around the under side of the larger drum and thence upward between the two drums, where the operator catches the paper and makes it fast to the core or shaft upon which the paper is to be wound. By reason of this provision the operator is not required to go under the machine, as has been required to be done in former devices of the class, and the work is therefore more readily and safely accomplished by the employment of the said apron.

- Other features and parts of the invention will be more readily understood by reference to the drawings/forming apart of this specification, and in which- Figure 1 is an end elevation of the windingmachine embodying my invention. Fig. 2 is a front elevation, partly in section, of the machine with the center portion omitted, showingthe apron or carrier and the various adjustingparts.

Similar numbers of reference are assigned to corresponding parts throughout the various figures of the drawings.

In the drawings, 1 represents-the frame of i thewinding-machine, preferably made of caststeel.

iron in the form shown herein. 2 represents a shaft driven by any suitable power and being journaled in the bearings 3, which are attached to said frame.

4 represents a large winding-drum'which is carried by the shaft 2. The small drum 5 is mounted upon the shaft 6, which is jour-' naled in the bearings7. The shaft 6 is driven by means of a belt connected with the shaft 2.

8 represents a displaceable receiving core or shaft upon which the paper is Wound or rolled. The core 8 is journaled in the vertically-adjustable boxes or bearings 9. These journalboxes are made in two parts, which are joined together by means of the hinged joint 9. The

upper half of the journal-box 10 is held in a closed position by means of the spring 11. The hand part 12 is provided for the purpose of opening and closing the box.

The guide-rods 13 in the present invention are preferably square in form and made of They are pivoted to the base of the frame at 14 by means of the pin 14'. The upper ends 13 of these guide-rods are loosely confined within the yoke or slotted aperture 18,v which is formed in the upper ends of'the arms 16 and 16. The aperture 18 is made large enough to permit of a slight lateral movement or vibration of the free ends 13 of v upon which the paper is rolled.

the guide-rods. A cap 19 closes the open end of the yoke or aperture 18 and is secured to the point of the arms by means of suitable bolts or screws. The guide-rods 13 are provided on one of their flat sides with a series of horizontal grad nations or scales 13 for the purpose of indicating the diameter or weight of the roll of paper. By the use of this scale the operator is able also to readily determine end of the roll of paper could also be raised separately. This feature was employed in the old device at times when the roll of paper for any reason built up or increased more rapidly at one, end than the other, and by manipulating the hand-levers referred to the roll could be kept substantially level throughhave shown an adjusting-shaft 20, which is mounted in the journaled bearings 21, supported by the upright arms 16 and 16 of the frame, preferably in the position and in relation to the other parts of the machine, as shown in Figs. 1, 2. and 3. The adjustingshaft 20 is not driven by power; but it is intended to be rotated wholly or partially by means of the hand-wh eels 23 and 25 and also'by its indirect connection with the sprocketchains located at either end of the machine, which connect with and are operated by the paper-roll during the winding of the same. The adjusting-shaft 20, as shown in detail, Fig. 5, is equipped with a number of cooperative parts which adapt the same to be operated to effect a number of different adjustments producing various results. Theseadjustments are accomplished in the first place by means of the hand- wheels 23 and 25, which have the effect of levers or cranks, mountedv on the end of the shaft, which projects out beyond the upwardly-extending. bracket-arms 16 of the frame. These hand-wheels are both disposed concentrically with shaft 20 and are capable of being rotated by hand either separately or together by means of afeather 26 and a clutch 27, the latter being interposed between said hand-wheels. The interlocking of the two hand-wheels by the aid of said clutch is maintained by means of the tension of spring 33. (Shown in Fig. 2.) The handwheel' 23 is secured to the hollow shaft or sleeve 22,,also' mounted on the shaft 20 by means of a feather 24, (shown in Fig. 5,) while the hand-wheel 25 is slidable on the spline or feather 26, (shown in the same fig ure,) and when in engagement with said spline is rotated with shaft 20. By this arrangement the wheel 25 may be pulled outwardly against the spring 33 until the clutch 27 is 7 released, as shown in Fig. 3, and then turned to the right or left to effect the desired adjustment. It will be noticed that the feather 26 does not extend beyond the hand-wheel when the latter is in engagement with the clutch 27 and wheel 23, and when hand-wheel 25 is pulled outwardly against spring 33 the full distance allowed it becomes free fromthe.

and 29 are preferably in the form of disks, and the disk 28 is provided on its face side with a series of sockets or holes 30, arranged in a circle in close order, as shown in Fig. 6. The disk 29 is provided with a series, preferably four, of dowel-pins or projecting points 31, (shown in Fig. 7,) which are arranged so as to engage corresponding holes 30 of disk 28, and by that means the handwheels 23 and 25 are interlocked and made to operate as one wheel or part. In Fig. 3 handwheel 25 is shown to be out of engagement with the clutch 27 and hand-wheel 23. The functions or objects of these adjustable means are as follows: In winding a fresh strip of paper upon the core or roll 8 as it comes directly from the calenders the web of the material throughout is not always of the same consistency and thickness, and therefore it is impossible to effect the even or smooth winding of the same upon the receiving-cores unless some compensating means are provided therefor. Sometimes one side is thicker or harder than the other, and at another time the same side or perhaps the center portion is harder or softer than the edges, and the rolls are often formed with sufiicient unevenness or irregularity as to distorttheir appearance and destroy their value for commercial use. For. this reason if one end of the roll of paper builds up or increases more rapidly than the other the operator will take hold of the handwheel 25 and pull it lengthwise of the shaft 20, so as to free it from engagement with the clutch 27. Then he will turn it either to the left or right, as the case may be, and reset the clutch in a position to effect the raising of the end of the paper-roll which requires leveling up. If the farther end of the roll requires leveling, then he will turn the hand-Wheel 25 to the right the required distance and set the clutch in a new position. This operation raises the farther end of the roll of paper, but does not affect the near end of said roll. In this connection it might be well to explain that when the hand-wheel 25 is freed from the clutch, but still in engagement with the feather 26, if the said wheel is turned in either direction while held in said position it Will effect the turning of the shaft 20, the pinion 43, and also spur-gear 4:0 and not operate the sleeve 22, the pinion 37, or the spurgear 40; but as soon as the hand-wheel 25 is allowed to connect with Wheel 23 by means of the clutch then the said shaft 20 and all of the connected parts, including both hand-Wheels, will operate together, and both ends of the paper-roll will be affected in the same way. By the raising of the farther end of the paper-roll as just described a certain amount of the weight of the roll will be relieved from the Windingdrum, and-the paper, therefore, will not be wound as tightly on that end of the roll as on the other end, where the weight has not been so relieved. In this manner the leveling up of the roll is accomplished, and when done the hand-wheel 25 is left in the position last named until the roll is complete. If the forward end of the roll becomes out of level, the operator pulls hand-wheel 25 out of engagement with clutch 37 and holds it While an-' other Workman turns hand-wheel 23 to the right a notch or more, and by that means the shaft 20 remains stationary, While the sleeve 22 and the pinion 37, keyed thereon, will be rotated thereby, and said gear being in mesh with spur-gear 40 will operate the latter, and through the sprocket-and-chain connections the weight of the roll of paper at the forward end will be relieved from the drums in the manner described. By the use of clutch 27,

hand- wheels 23 and 25, and shaft 20, together With the gears, sprockets, and chains, the entire weight of the roll of paper may be lifted off the windingdrums, or any portion of said weight may be relieved during the winding of the paper on the roll, as described. The adjusting-shaft 20 Will make from one to ten rei'olutions in Winding the different-sized ro ls.

A zero or level mark 44 is placed on the outer edge of each of the clutch-disks 28 29, as shown in Fig. 2. These are for the purpose of providing a gage by means of which the adjusting parts are set to bring the core or shaft upon which paper is to be wound in a true and level position. Before the paper is Wound on the core the hand-wheels are set with the zero-mark 44 on each corresponding. Then the receiving-core 8 is level. After a roll has been completed and removed a new core or shaft is placed in the journalboXes 9 and the hand-Wheels and shaft 20 turned backward till the core is lowered to the starting-point between the Winding drums. Then the operator sets the handwheels at zero, as described, and the core is started in a true and level manner.

The spring 33 is held in place on shaft 20 by means of the collar 34, secured to said shaft by the pin or set-screw 35.

The pinion 37 and the ratchet-gear 38 are cast in one piece and are secured to the sleeve 22 by means of the key or feather 39. Being thus made rigid on said sleeve, these parts all rotate together.

4:0 and 40 represent the large spurgears Which-are loosely mounted upon the stationary rod or shaft 41, secured to the upper ends of the arms 16 and 16. The rod 41 in addition to carrying the large spur-gears also serves as a tie or brace to the upper parts of the frame. The gears 40 and 40 are held in position opposite to and in mesh with the pinions 37 and 4:3 by means of the collars 42, which are made fast to the said rod by means of suitable set-screws. The sprocket-Wheels 4:5 and 45 are cast on the hubs of the spurgears 40 and 40, respectively. The said gears,

Ioo

together with the sprocket-Wheels, are revo- 46 represents a sectional view of the cen- V tral portions of the gears 40 and 4:0 and also of the sprockets 45 and 45'.

The sprocket-chains 4:7 and 47 are each provided with the .rod or link portion 49, which is threaded throughout its length, except its upper end, which is formed into a hook 50, by means of which the said rod or link is connected with one end of the sprocket-chain.

The lower end of the rod 49 is fitted with the nut 51, which is attached to said rod by means of threads. A loop 52 is formed upon the nut 51 and is adapted to connect with a link of the sprocket-chain. The threaded rod or link 49 is provided with the jam-nuts 54:, disposed immediately above the spring 55, and in addition to'holding the spring in place also serves as means for increasing or diminishing the tensionof said spring. The lower end of spring 55 bears against the laterally-extended arm or lug 58 of the journal-box 9,

. of adjusting the core or shaft 8 horizontally,

the full purpose of these parts just referred to being to afford a means of relieving or increasing the weight of the roll of paper upon the winding-drums when operated in connection with the adjustable means described and by the employment of the spring 55 to provide for slight vibration of the roll during the winding of the same.

The square guide-rods 1 3, which support the journal-boxes 9, pass through a square apertu-re '61, formed in the body of said boxes, as shown in Fig. 8. By this means provision is made for the sliding of said boxes upwardly and downwardly on said guide-rods. The rods13 have a slight lateral movement or play by reason of the yoke or slotted opening 18 and the pivot 14. The axis of 'thepaper-roll as it increases in diameter by reason of the sliding of the journal --boxes on the guide-rod 13 moves upwardly in a substantially vertical course, and the lateral play of the guide-rods merely provides for any vibra tion or oscillation of the roll of paper incident to the slight unevenness of the roll and the high rate of speed at which said roll is driven during the course of the winding.

The sprocket-wheels 62 are pivoted to the inner side of the frame at each end of the machine. These are employed for the purpose of supporting the sprocket-chains and preventing them from interfering with the other working parts of the machine.

The sprocket-chains at each end of the machine are provided with the turnbuckles 63, which are employed for the purpose of adjusting the length of said chainsthat is, to increase or decrease the slack or tension of said chains. The turnbuckle 63 is comprised of the body portions 64 and 65. These. two parts are connected by means of the screw 66, which is cast integrally with the body portion 65, the free end thereof being threaded to correspond with and engage the internallypasses through the hole 71 in the upper endof the body part and extends downwardly through the coiled spring 72 and the nut 73. The lower end of the bolt 69 is upset to form %a head on the under side of the nut 73. object of the said turnbuckle provided with a spring and bolt in the manner described and The shown 'is to permit of the body portion '65 being turned either to the right or to the left upon said bolt 69, as on a swivel, for the purpose of shortening or lengthening the sprocket-chain, and at the same time, by reason of the employment of the spring 72 in connection with the bolt 69 and the nut 73, a

certain amount of resilience or yielding tension is provided. This has been found to be necessary in order to prevent the cramping or breaking of the sprocket-chain in cases where too great a tension or strain has been occasioned by the operation of the turnbuckle or from other causes,

The ratchet-wheel 38, cast with the spurgear 37 and mounted upon the sleeve 22, is provided with the pawl 75, having the handle or lever 76 pivotally attached to the upright arm 16 by means of the bracket 77 and the ,pin 78. The said pawl is located so that it may. engage the ratchet-gear 38 and maybe thrown into or out of such engagement by the operator by *means of the handle 76. The object of this ratchet-gear and pawl is to enable the operator to sustain or hold the weight of an extra heavy roll of paper-in other words, to prevent the recoil of the shaft 20 during the opration of the hand-wheels and related parts when adjusting or raising aheav-y roll of paper.

The shaft 20 is also provided at one end with a'sma'll drum or sheave 80, as shown in Figs. 2, 3, 5, and 9, to which is attached the cable 81 and the weight 82. "The said cable is adapted to be coiled or wound around said drum in either direction, as shown by the full and dotted lines in Fig. 9. The object of the drum, cable, and weight referred to is to provide a suitable tension-and driving power for the shaft 20 and also for the large spur-gears and sprocket-wheels mounted on the stationary shaft or rod 41, the weight referred to being heavy enough to rotate the said drum and shaft 20, as well as the other connected parts. The weight 82 is also employed as a counterweight to retard the rotation of shaft 20, and therefore allow the paper-roll to bear less heavily upon the winding-drums." In case it is desired to rotate the shaft 20 toward the right the cable 81 is placed on the drum or sheave in the manner shown by the full lines in Fig. 9, and-when desired to rotate said shaft in the reverse direction said cable and weight are disposed as shown by the dotted lines in the same figure.

The web or canvas comprising the apron or carrier 85 is preferably about one foot in width and is endless in form, resembling a broad belt. This apron is mounted upon and carried by a series of rollers or drums, one of which, 86, acts as a driver for said apron. The other three rollers or drums 87 are merely idle carriers, disposed, preferably, as shown in Fig. 4c of the drawings, for the purpose of carrying and guiding the apron so as not to interfere with other parts of the machine. The preferred position of the apron or carrier with reference to the large drum 4 is substantially opposite the center or middle of said drum, as shown in Fig. 2 of the drawings. This has been found to be the most convenient and serviceable location for said apron, although it may at any time, if desired, be shifted toward either end of said drum and perform the same work. q '88 represents the four guide rods or bars upon which the apron rollers or drums 87 are adjustably and operatively mounted. These rods or bars are secured to the base of the frame at either end of the machine, as shown by the numeral 90. Before starting to wind the paper the broad end of the strip of paper is folded or cut in the form of a V, as shown by the dotted lines 91 in Fig. 2, the point of which corresponds with the center of the apron. To begin the winding, the point 91 of the paper is inserted or fed between the apron and the drum 4 at 87 at the front of the machine, and it is then carried around to the receiving-core in asmooth and even manner. The apron or carrier 85 during the whole course of the winding is held in contact with the large drum 4, as shown in Fig. 4:, under sufijcient tension to keep both the said apron and the web of paper even or flat against the surface of the said drum, thereby preventing the central portion of the strip of paper from becoming wrinkled or otherwise distorted. The apron drum or roller 86 is held constantly againstthe winding-drum 4 under a tension strong enough to insure its being driven, and thereby cause said apron to travel at the same relative speed as the drum and the paper. In practical operation the two winding-drums are driven in the same direction, (as indicated by the arrows in Fig. 1,) and the smaller drum being of less circumferential measurement must travel at a proportionately higher rate of speed. This is accomplished by the unequal pulleys 92 93 and the belt 94:. (Shown in Fig. 9.) By reason of the fact that the drums are of unequal size, as herein explained, the roll of paper, because of the position of its hearings on the pivoted guide-rod 18, will bear heaviest against the larger drum, as shown in Fig. 1, from which it will be seen that the angle of bearing with relation to the paper-roll and the large and small drums differs relativel y to the respective diameters of the drums and also to the relative position of the large and small drums.

The axisof the small drum, as shown by the drawings, is placed on a higher plane horizontally than the axis of the larger drum. The position of the two drums for producing the best results is preferred to be substantially as shown by the drawings.

96 represents a series of spirally-shaped grooves .or recesses which are formed or out in the surface or circumference of each of the drums 5 and 6, as shown in Fig. 2. These grooves or recesses are provided for the purpose of compensating for the rough or uneven calendering of the sheet or strip of paper. It frequently occurs that sections here and there in thelength and width of the continuous strip or web of paper are of different degrees of hardness. Sometimes one edge of the strip is thicker or softer than the other, and at other times the central portion for a distance is slightly different from either of the edges. For that reason I have provided the grooves on the surfaces of the drums, and in that way as the paper passes under tension between the drums and the receiving-roll such discrepancies are in a great measure compensated for by the paper being pressed or crowded into the recesses or grooves, which take care of much of the extra fullness or unevenness in the web, and the winding continues on the roll in a comparatively smooth and even manner. The grooves are formed spirally to prevent the paper from being fluted or crimped, as would be the case if the grooves were formed straight or horizontally with the drums. The grooves or recesses are preferably placed close together, about a quarter of an inch in width by one-eighth inch in depth, to produce the best results. They are arranged on each of the drums in the same manner, and both drums travel in the same direction when in operation.

97 represents the continuous length or strip of paper as it comes from the calenders and is received by the winder and wound upon the roll'98, as shown in Fig. l.

The hand-wheel 23 is provided with a groove 99 on its outer edge or periphery, which is adapted to receive a cable 100, to which is connected a weight or a series of detachable weights 101. This provision is made for the same purpose as the drum and cable 81 on the opposite end of shaft 20. The object in having the cable and weight at each end of said shaft is for the purpose of greater convenience in carrying out the operations of the winding-machine and also to provide additional weight, which is sometimes required in order to effect a proper'adjustment of the winding parts. The cables are attached to the drum 80 and the hand-wheel 23 in such manner that either or both of them may be quickly removed (see 80) if for any reason no weights are required. The Weights referred to are for the purpose also'of increasing or decreasing the pressure of the roll of paper on the Winding-drums. The weights may be used separately to affect the endof the roll at which they are attached and not the other end, or they may be employed to control or affect the entire shaft 20 and all the related parts.

The semicircular-shaped guard 103, having its bearings 104 on shaft 6, is provided with the projecting arms 105 andis connected with the rearwardly-extending lug 106 of thejournal-box 9 by means of the link or rod 107 and the pins108. This guard by reason of its connection with the movable journal-box 9 and its loose bearing upon the shaft 6 is operated automatically. When the receiving-core 8 is mounted in the movable boxes 9 and placed in between thev winding-drums, the guard 103, by means of the said arm and link, is swung forward to within an inch or two of the said core, and then as the roll of paper increases the guard is turned backward, but

always maintaining the same relative space or distance from the roll. The dotted lines at 109 represent the position of the core 8 with reference to the two drums at the start of the winding. 1 r

The stands or brackets 110, located at the rear of the machine at either end, are provided for the purpose of receiving or supporting the shaft or core 8 either before or after the paper is wound upon the same. These stands or brackets are secured to the frame in a suitable manner and for convenience are disposed as shown in Figs. 1 and 4.

111 represents a spreader for the paper, such as is commonly used in connection with paper-winding machines.

During the course of my experimenting and from actual practice with double drumwinding machines I have found that much better results are attained by the employment of drums of unequaldiameter and have found that the difference in size of the drums should be relatively about two to one. Where drums of the same size are employed, a roll of paper cannot be wound with the desired evenness and much difliculty in operating and great waste of time and material have resulted from their employment. The reason for this I have found to lie chiefly in the fact that the weight of the paper-roll will bear substantially evenly upon each of the two drums,

and for that reason in machines where drums of'equal size are employed the drums must be mounted and maintained so that their horizontal axes will be substantially on a level. It has also been found that one, preferably the first drum in the orderof the winding, must be at least two feet in diameter in order to produce the best results, and if the drums are of the same size the bearing-points of the roll of paper on the two drums after the roll has increased considerably in size becomes wider apart, and this has the effect of destroying the effectiveness of the winder. Under such a construction the same amount of weight of the paper-roll will be borne by each drum, and hence it has been found impracticable to increase the speed of the second drum to the extent necessary to produce compact and even winding without tearing or distorting the paper. On the other hand, by the use of the drums of unequal size, constructed as shown and described herein, the smaller drum is preferably placed at the rear of the machine and is brought nearer to the larger drum,thereby lessening the distance between the drums and the roll of paper, which is of great advantage in drum-winding machines, and the bearing-surface between the small drum and the roll is relatively only half as great as that between the large drum and the roll of paper. Hence as the weight carried by the smaller drum is so much less than that borne by the larger drum it has been found possible to provide for a slight increase in the speed of the small drum. This is accomplished by decreasing the diameter of pulley 93, mounted on shaft 6 'of the smaller drum, five to ten per cent. smaller than the proportional diameter of the two drums when driven at equal surface speed. This increase of speed is fixed at such a small degree that while it exerts a slight pull on the web of the paper, just. enough to keep it stretched tight on the portion of the roll already wound, there is not enough strain to cause the tearing or distorting of the material. 1f the winding-drums travel at the same rate of speed relatively and being kept constantly in contact with the roll of paper, which is increasing in diameter with each revolution, the layers or coils of paper after passing from the large or driven drum onto the roll apparently loosen or slacken, and it therefore became necessary to devise some means to correct or regulate this slight defect in the winding, which if allowed to continue for a number of revolutions would result in wrinkling or distorting the paper on the roll. Hence by reducing the size of the belt-pulley on the shaft which carries the small drum to the extent described it will increase the speed of said drum sufliciently to exert a slight pull on the paper, causing the tightening of the layers of paper, and thereby effect the cornpact and even winding of the roll. By reason of the faster travel of the small drum there is a slight constant slip of the said drum at the point where it makes the frictional contact with the paper-roll. By the use of the small drum, disposed as described, the workmen are able to get nearer to the roll of paper during the progress of the winding and are thus enabled to make splices or to do any other necessary work more conveniently. One of the chief advantages derived from the use of drums of unequal size arises from the fact that alarger surface or bearing contact is provided, and therefore a greater purchase is given to the roll of paper, which has been found to be necessary to properly carry out the purposes of the machine. It also allows the spool or core when first starting to wind to drop down between the rolls or drums a greater distance and still be within easy reach of the operator. Under this form of construction the angle of bearingor contact is such that it affords a better grip on the core or shaft upon which the paper is wound. By reason of'the difference of the angle of bearing or contact referred to a larger proportion of the weightof the paperroll is brought to bear upon the larger or power-driven drum, while the smaller drum only carries such proportion of the weight as is necessary to prevent or avoid deflection of the shaft or core on which the paper is being wound.

It is not claimed that the double-drum feature of the present invention is entirely new to the art, as machines having a plurality of winding-drums have been in use heretofore; but it is claimed that double winding drums or rolls of unequal diameter arranged and operated in the manner herein shown and described are essentially new and constitute an improvement over existing forms or makes of paper-winding devices.

Believing that the operation of my device will be fully understood in the foregoing, further special explanation thereof is unnecessary.

It is obvious that many of the details of the construction of the device may be varied without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
