PAPER HOLDER AND REWINDER.

Original application filed December 3, 1923, Serial No. 678,213. Divided and this application filed April 28,

1927. Serial No. 187,392.

My present invention is a novel and improved paper holder and rewinder, and the present application is a divisional of my prior and (lo-pending application, Serial No. 678,-

213, filed December 3, 1923, which matured into Patent No. 1,681,033.

While my invention is applicable to ma-- chines of the kind described in my said prior application, his not limited thereto, but has a wide range of application and utility.

A novel characteristic of the present paper winder and holder is the open Sided construction, whereby large and heavy rolls of paper or other yielding material or backing webs can be readily applied and removed quickly and easily, practically without-interruptionin the operation of the machine associated with my holder and winder. As these rolls are heavy and bulky and have to be frequently replaced, the advantages of my present open sided construction is of great value, and I claim these features herein broadly. An important feature of my present invention is the utilization of practically every portion of such paper, moving same step-bystep just sufficient to disaline the succeeding cutting actions of the machine. My present device obviates the objections to prior structures, and enables me to utilize every available portion of paper in a strip of indeterminate length.

A further feature of the invention consists in the provision of a paper holding roll or shaft, graduated in such a manner that the roll or reel of paper may be placed in a predetermined position onsaid shaft.

' A further featureis the utilization of novel tensioning, alining, and holding means for said roll of paper. A still further feature 40 consists in novel means to advancethe roll of paper through the machine in a predeter-.

mined step-by-step ,or intermittent progressive movement.

A further feature resides in the fact of the rewinder being driven when the machine is in motion, so that the rewinder will wind faster 7 than the slack is formed by the paper as-fed through the feed rolls of the machine, the belt driving the rewinder slipping in a groove pulley when thepaper is taut, this drive being a friction drive. I

Further features of the invention, details,

combinations of parts, and advantages, will be hereinafter more fully pointed out and claimed. I

Referring to the drawings, illustrating a preferred embodiment of the present inventlon,

Fig. 2 is a rear elevation of said machine;

Fig. 3 is a front elevation of the machine;

Fig. 4 is an enlarged detail on the line 4+4 of Fig. 2;

Fig. 5 is a vertical sectional elevation on the line 5-5 of Fig. 3; and

Fig. 6 is a cross-sectional View on the line 6--6 of Fig. 3. v

As shown in the. drawings, 1 designates a base having formed integrally therewith and extending upwardly therefrom a body 2 of a machine, which machine is adapted to rest on a bench or other support, and rotatably mounted in bearings 3 formed in the body 2 and adjacent the top thereof is a power shaft 4. Keyed to the shaft 4 intermediate the ends of such shaft and between the bearings 3 is an eccentric (not shown), on which is-rotatably mounted an eccentric ring (not shown), that is, in turn, adjust-ably mounted for rotation in an eccentric strap 5, this eccentric strap being split at one end and this end being provided with extending lugs 6. One of these lugs 6 is drilled as a clearance hole for the body of a bolt 7 while the other of the lugs 6 is drilled to receive the threaded end of such bolt 7 and this bolt 7 is utilized, in connection with the lug 6, as a means for drawing the split end of the eccentric strap together in order to clamp the eccentric ring therein. This eccentric strap 5 is formed integral with one end of a connecting rod 8, the

other end of this connecting rod being pivotally attached to a shaft 9 secured on the lower end of a cross head or pressure member 10. This cross-head 10 is slidably mounted for vertical movement in guideways formed on the machine by means of straps 11, these straps being secured to the machine by bolts 12. The plunger or crosshead 10 is provided on its lowerend with a removable face 13. Formed integral with the body 2 and extending forwardly therefrom is a table or platen a wedge-shaped member 22.

clearly shown in Fig. 3.

14, which platen is provided on its upper face and on either side thereof with guideways for a purpose to be hereinafter described. The platen 14 lies in the path of movement of the vertically movable cross-head 10.

Rotatably mounted on the main shaft 4 and at one end thereof is a driving pulley 16 with an inner hub 17, power being furnished from any suitable source to such pulley 16 to drive the machine. The inner face of the hub 17 of the driving pulley 16 is counterbored and secured to the bottom of such counter-bored portion is a member provided on the face thereof adjacent the opening of the counter-bored portion with two radially arranged sectors 17*. Secured to the shaft 4 is a member 18 provided with a longitudinally arranged slot 20. Slidably mounted in this slot is a rectangular plate 19, a spring 21 being arranged between the end of the slot 20 and such plate 19, which spring tends to force the plate 19 to the right, as viewed in Fig. 3 or into such a position as to engage with one or the other of the sectors 17 The plate 19 is provided on its outer edge with a V-shaped slot 19 in which is adapted to fit In the position shown in Fig. 3, with the wedge-shaped member aa in the slot 19 the plate 19 is held to. the left against the tension of the spring 21, and with its outer end out of engagement with wedge-shaped sectors 17. Under these circumstances, the pulley 16 will be freely rotatable on the shaft 4, and the shaft 4 will member 22 is withdrawn from the V-shaped slot 19 in the plate 19, the spring 21 will force the plate 19 to the right, as viewed in Fig. 3, and such plate will be engaged by one or the other of the wedge-shaped sectors 17 in the hub 17, thus locking the pulley 17 and shaft 4 together, and this condition will prevail until the wedge-shaped member 22 is replaced in its original position to engage in the wedge-shaped slot19 in the plate 19. The wedge-shaped member 22 is secured to the upper end of an arm 23,1'otatably mounted on a shaft 24 secured in a member 25 attached to the body 2 by bolts 26. The member 25 is provided with a projection 105 which extends outwardly toward the pulley 16,-and secured to the end of this projection is one end of a spring 106, which spring is coiled around the hub of the arm 23 and extends upwardly, its upper end entering a perforation near the upper end ofthe arm .23, as This spring 100 is arranged to cause a rotative movement of the arm 23 about the shaft 24 in a clockwise direction, so that, normally, such arm 23 will maintainthe plate 19 in its left hand position, as viewed in Fig. 3, against the tension of the spring 21, and therefore the pulley 16 is free to rotate on the shaft 4.

Since the machine illustrated herein is only about the bolt 37 as a center.

a single revolution of the shaft4 by power 1 transmitted from the pulley 16. Arranged for sliding in the guidcways 15 on top of the platen 14 is a base 27, which is secured thereon, and at its upper end a cutting anvil 28, the details of which are described in my prior application. Adjustably secured to the top of the platen 14 and at'its rear end is an anvil rest 29, which anvil rest acts as a support for the. relatively unsupported end of the cutting anvil 28. Secured to the frame of the machine is a stop plate 30, which lies in the path of movement of the anvil 28, and in such relation thereto thatwhen the cutting anvil 28 engages the stop plate 30, the die on such cutting anvil will be accurately positioned in the line of travel of the plunger 10. A mask- 31 is hingedly secured to the rear end of the cutting anvil 28 by a hinge 32. And a shoe upper 33, to be cut or died out, is in position on the cutting anvil 2S.

The application of my novel paper holder and rewinder to a machine of this type will now be described.

Secured to the body 2 and at one side thereofflby bolts 35 is a member 36. Pivotally attached to the rear end of the member 36 on a'bolt 37 is the lower end of a standard 38. T he member 36 is provided with a portion 39 above the pivot bolt 37, and this portion 39 is provided with an areuate slot 40 through which passes a bolt 41 that screws into the standard 38. By means of the arcuate slot 40 and bolt 41, the standard 38 is capable of limited adjustable movement At the upper end of this standard 38 is secured by set screw 42, a shaft 43, which shaft lies parallel with the driving shaft 4. On the shaft 43 is adapted to be placed a roll of paper or other yielding material 44, and on the shaft and at each side of the roll of paper 44 are

adjustable brackets

45, 45, each carrying

spring tension members

40, 40. The brackets 45 depend from the shaft 42-3, and are positioned in substantially close relation with the roll of paper 44, the springs 40 being pressed against the paper and the brackets 4.5 to exert a spring resisting friction on the roll 44. As shown in Fig. 2, this shaft 43 graduated, from a point 45" at its cent-er to each side thereof. These grathurtio-ns facilitate the positioning of the roll 44 on the shaft 43, and permit greater accuracy in such positioning. The brackets are adjustably secured to the shaft 43 by screws 47. Secured to the front of the body 2 and at the top end. thereof is a curved guide plate 48 provided at either side thereof with adjustable guide plates 49 for guiding the edges of the paper 50 fed from the roll 44.

The front of the body member 2 below the curved guide plate 48 and on either side of such body member is provided with vertically extending lugs or ears 51, and to each of such ears 51 is pivotally attached the lower end of a bearing arm 52. Screwed into the front of the body member 2 and extending through a perforation in each of the bearing arms 52 is a thumb screw-53, and located between the head of such thumb screw 53 and the associated bearing arm 52 is acoiled spring 54, which tends to force the bearing arms 52 about their pivot point as a center in an anti-clockwise direction. Rotatably mounted at the upper end of the bearing arm 52 is a shaft 55 on which is secured a roller 56, which roller bears against the paper 50 as it passes over and around the curved guide plate 48. Secured to the lower end of each of the guide plates 11 and extending forwardly outward therefrom, as shown in Fig. 1, are studs or rods 57. Numeral 58 designates a curved guide plate over which the paper 50 passes, and secured to the rear face of such guide plate in any suitable manner are lugs 59 spaced apart from each other and drilled to each receive one of the studs or rods 57, acting thereby as a means for positioning the curved guide plate 58 on the machine. The lugs 59 are drilled and tapped to receive the thumb screws 60 and by means of which the curved guide plate 58 may be adj ustably mounted on the studs or rods 57. The upper portion of the curved guide plate 58 is provided with a pair of slots 61 in alinement with each other,

"as clearly shown in Fig. 3, and passing through such slots are studs 62 that are threaded at their outer end to receive a thumb nut 63. The studs 62 and thumb nuts 63 7 act as means for securing and adjustably po-v sitioning on the outer end of the face of the curved guide plate 58 the edge of the guides 64 arranged one on either side of the strip vided with a longitudinal slot 74 in which is adj ustably mounted by a bolt and

nut

75 and 76, respectively, the lower end of a connecting rod 77. Pivotally mounted in the bracket 73 on parallelly' arranged spaced shafts 78 are pawls 79, springs 80 associated one spring with each of the bolts 79 forcing such pawls into engagement with the ratchet wheel 72. It will be obvious, from an inspection, for example, of Fig. 4, that an oscillatory movement of the bracket 73 will cause an intermittent or step-by-step movement of the ratchet wheel 72, and therefore the shaft 70, in the direction of the arrow shown in such figure.

Secured to the shaft 4, remote from the driving pulley 16 is a face plate 81, provided with a radial slot 82 in which is adjustably mounted by means of bolt 83 and nut 84'the upper end of the connecting rod 77. The

radial slots

74 and 82 make it possible to alter the extent of oscillatory movemept of the bracket 73 imparted to it by the intermittent rotary movement of the shaft 4. Pivotally mounted on the body member 2 on each side of said member and above the corrugated wheel 71 are arms 85, and rotatably mounted on such arms in suitable bearings formed therein is a shaft 86, such shaft lying above, and parallel to the shaft 70. Secured to the shaft 86 is a corrugated feed roll 87, which 00- operates with the corrugated feed roll 71 above described. Each of the arms is provided adjacent its free end with an elongated vertical slot88 through each of which passes a stud 89 that screws into the body member 2, as clearly shown in Fig. 5. Between the end face of thehead of the stud 89 and the upper surface of the arm 85 is arranged a coiled spring 90, which exerts a downward tension on the arm 85 andtends to hold the corrugated roller 87 in engagement with the corrugated roller 7. The paper 50 is fed between the corrugated rollers 71 and 87, and intermittent rotary motion being imparted to the corrugated roller 71 by the oscillatory movement of the arm 73, and the paper 50 will be fed rearwardly of the machine. Secured between the body member 2 and the bearing arms 85 and located above, and extending transversely of, the paper 50, is a guide rod 91. The paper passes under such guide rod 91 and is loaded rearwardly of the machine. The portion of the rod91 directly engaged by the body member 2 and arms 85 is flattened, or non-circular in shape, as clearly shown in Fig. 5, and it will be obvious, therefore, by rotating such rod by means of its handle or eye 92 that the end of the arms 85 will be lifted up, separating the corrugated roll 87 a sufficient distance from the corrugated roll 71 to allow the strip of paper 50 to be threaded therebetween. Formed intermediate the ends of the standard 38 is a bearing 93 in which is rotatably mounted a shaft 94, which shaft lies parallel to the shaft 43 above described. Secured to the end of the shaft 94 by set screw 95 is a grooved pulley 96. Formed on the hub 17 of the driving pulley 16 is a pulley groove 97 that is in alinement with the pulley 96 and in the pulley grooves runs a belt 98 and by means of which passes through the bearing 93. This enlarged portion is provided with a longitudinally extending keyway or groove 100. Slidably mounted on the enlarged end of the shaft 94 are collars 101, each providedwith a threaded hole to receive the thumb screw 102, the end of which is guided into the keyway or groove 100. By properly adjusting the collars 101 on the enlarged end of the shaft 94, strip of paper 50 is properly guided, as clearly shown, for example, in Fig. 2. Each of the collars 101 is provided with a hole, the holes being in alinement with each other, and through which passes a rod 103, which rod is provided at its end with an eye 104 and by means of which the rod 103 may be handled or operated. The end of the strip of paper 50 is folded over about two inches from its end and placed under the rod 103 by revolving the shaft 94, the end of the paper 50 is started on to the shaft 94. After the paper has been used and wound from the shaft 43 to the shaft 94 it may be easily removed from the shaft 94 by withdrawing the rod 103. While placing the folded end of the strip of paper under the rod 103, and while adjust-ably securing the collars 101 in position, the wing set screw 99 is utilized to hold the shaft 94 against rotation.

The operation of my novel paper holder and rewinder, in the particular machine illustrated herein, is as follows, the machine itself not being described in detail, but only in so far as is necessary to show the co-relative operation of the paper holder and rewinder, and its component parts in a machine of this character. An appropriate cutting anvil 28 having secured thereon a cutting die in which is fashioned the particular design desired to be cut from the material is provided. Any design desired may be utilized. A mask 31 is also provided with an appropriate cut-off of such shape as to allow any desired part of the upper to be clearly fed through such opening. This mask is attached to the cutting anvil 28 by the hinge 32. The supporting post 29 is now positioned on the platen 14 in such manner that the die attached to the cutting anvil 28 will be located beneath the plunger 10 when the base 27 is in its rear-most position and against the stop plate 30 and resting on the supporting post 29 in balanced relation to tllO design of the die so that equal pressure will be placed on all parts of the die. A roll 44 of paper 50, such paper being of substantial thickness as compared to the thickness of the material being worked on, is placed on the shaft 43. Such placing on the shaft is simple,

the outer bracket 45 being removed, the roll 44 placed on the shaft, and positioned in predetermined position, determined by the gradnations on the shaft 43, whereupon the brackets 45 are moved in substantially close relation with the roll 44, providing a friction tension on the roll, assisted by the springs 46. when the roll 44 and brackets 45 are appropriately positioned, the screws 47 are then tightened, insuring rigid positioning of the roll on the shaft 43. The paper 50 is then drawn over and around the curved guide plate 48, and under the guide tension roll 56, the guides 49 secured in position, the paper passed over the curved guide plate 48 rearwardly of the machine, between the corrugated rolls 71 and 87. as above described, the end of the paper 50 folded and passed under the rod 103 and around the shaft 94.

T be horizontal plane in which is located the cutting edge of the die, is spaced apart from the horizontal plane in which lies the lower face of the facing attached to the plunger 10 when such plunger is in its lowermost position, a distance less than the thickness of the strip of paper 50. The strip of paper 50 will, therefore, act as a die block against which the cutting edge of the die works and as a new portion of paper is presented to the dies at every stroke of the press there is, in reality, a new die block brought into association with the die at every stroke of the press. Further, as the strip of paper 50 is never entirely cut through by the cuttingdie, the amount ofniovement of the strip of paper for each stroke of the plunger need only be sufficient to present a new uncut surface to the die, and in practice, such movement of the paper 50 need only be approximately one sixteenth of an inch. In addition to the advantage of having practically a new' die block presented to the cutting die at each stroke of the plunger, there is the added advantage that but approximately one sixteenth of an inch of paper of the strip 50 is used up at any one stroke of the die instead of the using up of a strip of paper of much greater length as has heretofore been the custom. It being assumed that the paper 50 is threaded through the maehine,the appropriate die and mask fitted on the cutting anvil 28, and the stop block 29 properly adjusted, power may now be thrown on to the machine through the pulley 16. The operator slides the base 27 back, or to the right, as viewed in Fig. 1, throws the mask 31 into an upright position, places an upper 33 into approximate position over the die, then swings the mask 31 downward so that it will engage with the upper, and by grasping said upper on either side of the cutting anvil 28, the out-out portion of the anvil may be utilized as a means for registering and centering the upper with respect to the design on the die even though such die is hidden from view by the upper. The. operator now moves the base 27 with the 'atpatent, in withdrawing the wedge-shaped member 22 from the V-shaped groove in the plate 19. This allows the spring 21 to force the plate 19 to the right, as viewed in Fig. 3, and into the path of movement of the wedgeshaped sectors on the hub 17. Rotary motion is therefore imparted to the shaft 4 which, by

means of eccentrics within the eccentric strap 5 will cause a downward movement of the plunger 10, thus bringing the facing on the bottom of such plunger against the paper 50 and forcing the paper 50 into engagement with the cutting die. Such engagement, will cause the cutting die to penetrate the strip of paper, but will not pierce the same, whlch results, to all outward appearances .on one face thereof, at least, in leaving the paper intact. As described in my patent, the machine under consideration has a positive one revolution clutch, and'but one revolution can be imparted to the shaft 4 by one operation of the treadle rod 104, which must of necessity be returned to its initial position for each separate revolution of the shaft 4. v

Rotative movement of the shaft 4 causes, also, relative movement of the face plate 81 and, therefore, a complete 'reciprocatory movement of the connecting rod 77 for each complete revolution of the shaft 4. Reciprocatory movement of the connecting rod 77 imparts a reciprocatory movement to the arm 7 3 and the pawls 79 engaging with the ratchet wheel 72, imparts an intermlttent rotary movement to the shaft 70. The corrugated feed roll 71 on the shaft and the corrugated feed roll 87 gripping the paper 50 therebetween, imparts a feeding movement to the left, as viewed in Fig. 1, to such paper. As the slight length of paper 50 is fed to the left, as viewed in Fig. 1, by the feed rolls 71 and 87, this creates a slackness in that length of paper extending from the corrugated rolls to the shaft 84. The belt 98 1s rather slack on the pulley 96, and 1n the pulley groove 97, thus allowing slippage between the belt 98 and the pulleys but such that the shaft 84 constantly tends to pull the strip of paper 50 from the feed rolls 71 and 87. As soon as such slack is created in the length of paper 50 from the feed rolls to the shaft 84, the belt 98 will rotate the shaft 84 suflicient to take up such slack.

The sequence of operations above described may take place indefinitely, the paper 50 being moved step-by-step across the path of the plunger 10 to present a new -uncut surface to the die and the extent of each step by step movement is suflicient for this purpose and is short'enough to insure that practically every bit of paper is used.

Due to the novel open-sided construction of my machine, removal and replacement of the wound and rewound rolls of paper is greatly facilitated, shortening the length of time heretofore necessary for such operations and consequently increasing speed and efiiciency of the machine.

While I have necessarily shown and described the preferred embodiment of my invention somewhat in detail, it is to be understood that I mayvary the size, shape and arrangement of parts within reasonably wide limits without departing from the spirit of the invention, and that my novel open-sided paper holder and rewinder is applicable to other machines than that with which it is utilized herein.

It will also be appreciated that I am not limited to the use of paper in the present machine, but may utilize other yielding ma terial, or any material suitable for backing.
