- Fig. 10 is an elevation of a sheet of paper or other material after passing through the perforated rolls, the arrows indicating the two directions in which it progresses.
- the numeral 1 designates the framework of the machine in which is journaled a shaft 2 carrying a'plurality of circular disks 3 adjacent to the periphery of which is an inclined slide 4, at one side of which is an adjustable guide 5, having a guide surface 6 extending therefrom across the face of the slide.
- a shaft 7 extends eccentrically through these disks and is journaled in them.
- This shaft carries adjacent to each disk a gripper'8 secured to the shaft and rotatable therewith. These grippers are adapted to press against a series of pads 9 fixed to the faces of the disks when the shaft is rotated by means which will be described later.
- a crank 10 Secured to the shaft 7, adjacent to the first disk, is a crank 10, pivoted to which is an arm 11 passing through a guide block 12 on the surface of the disk.
- the spring 13 is provided for causing this arm 11'to advance as far as it may into the block 12, thereby carrying with it the crank 10 and causing the grippers normally to press against the sockets .9.
- Secured to the shaft at either end are the trippe'r fingers 14 and 15, which are adapted to engage, respectively, the abutments 16 and 17 at defi- V nite periods in the rotation of the disks.
- perforating rollers are carried on a shaft 28 journaled in the frame and terminating in a gear 29 meshing with a large gear 30 upon the shaft 2.
- the continued rota tion of the disks carries the paper under the guide rollers 31 mounted upon the arms 32.
- the disks 3 are made of such size that their periphery is slightly greater in length than the longest length of paper to be used in the machine. Therefore, by the time the paper has passed beyond the rollers 31, but before it has passed the edge of the slide, its other end has left the slide and is wrapped about the disks 3. An instant later, through the action of the cam 21, the tilting fingers 19 are lowered into the position shown in Fig.
- the grippers 8 fly back from engagement with their pads and the front edge of the paper, thus released from the roller, passes between the stationary guides 33 and the tilting fingers, and continues in a straight line between the table bed 3% and the long horizontal guides 35 extending over the bed.
- the paper reaches the bed of the machine, and before its other end has left engagement with the rollers 31 and the disks, its front edge passes between the power-driven roller 36 and the rollers 37.
- rollers 36, 38 and 39 each project slightly above the bed of the machine, are continuously rotated by means of a chain 40 passing over sprocket wheels in the ends of the respective shafts 41, 4:2 and 43, to which these rollers are secured, and the sprocket 44, power being applied to the shaft 73 carrying the spur gear 72 which meshes with gear 74 and drives the same, and which carries upon its extremities the fiy wheel i7 and pulley 4-8, by which power may be supplied to the machine.
- the rollers 37 are carried by arms 49 secured to the shaft 50 which is journaled in uprights 51 secured to the frame of the machine.
- rollers 52 and 53 are mounted, respectively, on arms 55 and 56 secured to shafts 57 and 58 extending over the bed plate and j ournaled in uprights ex tending above the main framework of the machine. To these shafts are also respectively secured cranks 59 and 60 joined by a link 61.
- crank 62 pivoted to which is a link 63, the slotted end'of which, 6 embraces a shaft upon which is mounted a cam 66, against the surface of which contacts the roller 67 mounted upon the link 63.
- the shaft 65 is rotated by means of a spur gear 68 secured thereto which meshes with a gear 69 on a shaft 70, which in turn carries a gear 71 meshing with the gear 7 2 on the shaft 73, the gear 7 2 in turn meshing with the idler 7 4 upon the shaft 75, which meshes with the gear 30.
- rollers 52 and 53 are secured to the shafts 57 and 58 in such a Way that the utmost precision and speed of operation are Shortly before the obtained.
- This construction is illustrated in detail in Fig. 9, and while it will be described as applying to shaft 57, it is to be understood as applying equally well to shaft 58.
- a collar 77 carrying a pin 78.
- a second collar 79 having a slot 80 therein for the accommodation of the pin 78 and wider than the pin.
- To the collar 79 is secured the'arm carrying the roller 52.
- the arm 55 is in constant engagement with the roller 52 during the time when it is lifted from the surface of the paper and when it is in positive driving engagement with the latter.
- the paper 81 as it now lies upon the bed plate of the machine, is in the condition indicated in Fig. 10; that is, with parallel rows of perforations 82 passing completely across the face thereof in a direction parallel to its last motionacross the bed'plate.
- the rollers 83 upon the shaft 84 are automatically lowered from the position shown in Fig. 2 until they contact with the constantly powerdriven rollers 85 beneath them.
- the rollers 85 are carried by the shaft 86, which bears at one extremity a beveled gear 87 meshing with a gear 88 upon the inclined shaft 89 carrying in its lower end a beveled gear 90 meshing with a beveled gear 91 upon the shaft 73.
- rollers 85 are also constantly rotated at uniform speed.
- the mechanism for causing the rollers 83 to contact with the rollers 85 includes the cranks 92 keyed to the shaft 93, which is caused to oscillate by means of the arm 94, link 95, lever 96, pivoted at 97 and carrying at its lower end a roller 98 which bears against the face of a cam 99 secured to the shaft 65.
- the shaft 108 being carried by brackets 111 and 112 extending fromv the framework of the machine.
- the rollerslOO and 101 are equal in size and are rotated at the same peripheral speed as the roller 85, so that the paper is" smoothly carried under the guide 113 into engagement with the tworollers 114 and 115, whose axes are parallel to the axes of the rollers 100 and 101.
- the roller 114 is an idler, the shaft 116 of which rotates in a slot 117 in a skeleton structure 118 extending acrossthe edge of the bed plate.
- the roller 115 is power-driven by means of a chain 119, which passes over the sprocket 105 and idler 120.
- This roller therefore revolves at the same peripheral speed as rollers 100 and 101 and the paper continues its even course between therollers 114 and 115, after leaving which it passes between another set of rollers 121 and 122'.
- the rollers 121 are driven from the shaft 108 by means of the beveled gears 123 and 124. It is to be noted, however, that the gear '124 is substantially larger in diameter than gears 107 and 109, and that gear 123 is correspondingly smaller than gears 106 and 110, with the result that the rollers 121 and 122 which are geared together by means of the gears 125 and 126, have a substantially greater peripheral speed than the rollers, which have hitherto been in engagement with the paper.
- rollers 121 and 122 As the rollers 121 and 122 continue to revolve, this strip of paper is carried forward between the guides 113 and the bed plate until it is deflected from its course by means of the rollers 128 and 129, the line of centers of which is inclined to the vertical, as indicated most clearly in Fig. 5.
- Rollers 129 are positively driven from the rollers 122 by means of gears 130 and 131.
- Rollers 128 are idlers mounted upon arms 132 depending from a stationary shaft 133.
- the peripheral speed of rollers 129 is the same as that of rollers 121 and 122, so. that the paper is now carried forward without tension.
- a novel result,-however, is accomplished by inclining the line of centers of the two sets of rollers 128 and 129.
- the end of the paper is deflected downward,as indicated at 134. Striking a new bed plate 135 at a lower elevation, the paper slides along it, but there is a torsion produced in the paper, since the propelling influence is not now in the line of its motion.
- the forward edge of the paper continues under the guide 136 until it reaches the stop 137.
- the distance between the stop and the lastmentioned rollers is greater than the width of a strip, and therefore the rear edge of the strip of paper has passed between the rollers 128 and 129 by the time its forward edge reaches the stop 137.
- the rear edge is flipped down upon the bed plate and lies smoothly thereon, making way for the forward edge of the next strip to pass across and above it.
- This flipping action is highly important when the machine is running at high speeds, as it automatically causes the paper to lie flat upon the bed plate in a much shorter interval of time than would be possible if gravity alone were relied upon to accomplish the same result, and absolutely prevents conflict between the rear edge of the strip of paperwhich has just passed through rollers 128 and 129 and the forward edge of the next strip which succeeds it in a very short interval of time.
- the strip is induced to aline itself evenly along the guide or stop 137 by means of the flipper wheel 138, which is mounted on a shaft 139 carried by a bracket 140 secured to the framework of the machine.
- a belt 141 passes over pulley wheel 142 on the shaft 139, over guide wheel 143 and the pulley 144 carried on the end of the shaft 108.
- the flipper wheel consists of a hub 145, to which is secured a plurality of resilient members 146 radially disposed about the periphery of the hub. These members are preferably made of felt, leather or some other pliable material, and the function of the flipper wheel, which revolves in the direction indicated by the arrow in Fig. 2,
- the stop is automatically lifted by the rotation of the arms 147 about their shaft 148. This is accomplished by the action of the arm 149 secured to the said shaft and the link 150 pivoted to this arm.
- the lower end of the link is fashioned into a slotted member 151 embracing the shaft 152, which is rotated from the shaft 65 by means of beveled gears 153.
- the shaft 152 has secured thereto a cylindrical cam 154 engaging the surface of which is a roller 155 mounted on the side of the link 150.
- the arms 147 are preferably made adjustable, having the slots 156 through which protrude nuts 157, so that the arm may be clamped in a variety of po sitions with respect to the carriage 158, and thus accommodate various widths of strips of paper, the maXiInum width being sub stantially that provided for by the adjustment shown in Fig. 5.
- the fingers 159 are forced longitudinally along the slots 160 in the bed plate by the bar 161, to which they are secured. Weights 162 attached to the ends of cords 163 passing over the pulleys 164 are secured to the bar 161. These weights impel the bar toward the pulleys 164 when the roller 165 secured to the end of the lever 301 enters a cam 300, secured to shaft 152, the arms 166 secured to shaft 167, to which lever 301 is also secured, and being connected to the bar 161 by means of links 168.
- the passage of the fingers 159 through the slots carries the pile of strips of paper across the bed plate and into engagement with the rotary knives 169 and 170, the paper pass ing beneath the guides 136.
- the pressure between the rotary knives may be adiusted by compressing the springs 180 through the tightening of the bolts 181, the bearings being slidable vertically in the blocks 182 and, 183; As the paper passes between these rotary knives it is out in lines parallel to the direction of its motion and at the same time carried forward until it encounters the positively driven rollers 184 and the idle rollers 185 secured to the arms 186 depending from the shaft 187 secured to the framework of the machine.
- roller 188 As the paper continues onits course it passes across the face of the roller 188, which carries the gear 189 meshing with the gear 190 on the shaft of the roller 184. Rollers 184 and 188 therefore rotate in opposite directions. Roller 188 is driven through beveled gears 191 and 192, the latter being mounted on the shaft 193 which is positively driven from the shaft 172 by means of sprocket wheel 194 and chain 195. The cut piles of paper thus eventually pass underneath the guides 196 and come to rest against the stop 197, to which the guides are secured.
- the tucker blade 198 carried by the curved levers 199 which are pivoted to the shaft 200 descends between the rollers 184 and 188, carries the paper between these rollers, which rotate in opposite directions and therefore facilitate this operation, and the paper passes between the guides 201 and 202 into the box-like structure 203, this operation being illustrated in 5.
- the extremity of one of the curved levers 199, remote from the blade 198, is pivoted to a link 204, the end of which is slotted at 205 and embraces the shaft 152.
- the roller 206 mounted upon this link contacts with the surface of the cylindrical cam 207. When the portion of maximum radius 208 of this cam engages the roller it forces the link radially away from the axis of the cam, thereby causing the blade 198 to descend, as already described, the position of the cam upon the shaft 152 being adjusted to bring about this result at the proper instant already indicated.
- the cross-head 209 Immediately after the folded paper has descended into the box 203, the cross-head 209, operating in slot 210 in the opposite walls of the box 203, advances in a righthand direction with relation to Fig. 5, causing the folded paper to move laterally in the direction of the arrow until it is brought to rest, still in an upright position, against the buffer weight 211.
- the cross-head 209 is secured to an arm 212 which is connected by 1 means of the link 213 to a lever 214 pivoted at 215 to a shaftjournaled in the main frame.
- the lower extremity of this lever is pivoted at 216 to a link 217, the end of which is slotted at 218, and embraces the shaft 152.
- the link 217 carries near its lower extremity aroller 219 which contacts with the surface of a cylindrical cam 220 keyed to the sllaft 152. As the portion of this cam of shorter radius engages the roller 219, the link 217 will move toward the axis of the cam, thereby oscillating the lever 214 and causing the cross-head to advance within its slot through the agency of the link 213. Succeeding piles of paper will pass through the same operation, being stacked up as indicated at 221 in Fig. 5. When the requisite number forming a complete book or pamphlet has been collected in the box 203, they may readily be lifted out and are then ready for the bindery. These sheets are maintained in an upright position in the box 203 partly through engagement at one side with the buffer 211 and at the other with the abutment 222 and the lower portion of the guide 202. i
- FIGs. 7 and 8 it will be seen that they illustrate a modification, the purpose of which is to provide a machine in which the piles of paper, as they are delivered from the rotary knives, are folded in a direction parallel to their motion instead of perpendicular thereto, as was the casein the mechanism just described.
- the modification illustrated in these figures is an alternative for the folding mechanism previously described and is so designed that it may replace the other in the machine without requiring any considerable structural changes therein.
- the parts which remam unchanged are therefore given the same numerals in these figures as in Figs. 1 to 6, inclusive.
- the blades 230 which, together with the curved levers 231', replace the blade 198 and the curved levers 199, descend between the pairs of rollers 232 and 233, being actuated by the same mechanism which caused the curved levers 199 to oscillate about the shaft 200.
- the rollers 232 and 233 are rotated in opposite directions, that is, toward each other, the rollers 232 being driven from the shaft 193 by means of the beveledgears 234, and the rollers 233 being driven from the rollers 232 by means of the chain drive 235.
- the paper progresses downward in substantially the same manner as before into a receiving box 236 which has replaced the box 203 upon the shelf 237.
- This box has a curved side 238 formed in the arc of a circle whose center is located in the axis of the shaft 239, which is rotatably mounted in a sleeve 240 forming an extension of the box 236.
- a wing 241 Fastened to the upper end of the shaft 239 is a wing 241 which normally has the position indicated in Figs. 7 and 8.
- this lever 247 causes the rotation of the arm 243 and therefore of the shaft 239 to which it is secured, and effects the piling of successive folded piles of paper into the position indicated at 242 in Fig. 8.
- the extremity of the arm 243 opposite to the pin 244 carries a second pin 251, to which is pivoted a link 252 for actuating the other two Wings 241, the movement of the three therefore being simultaneous.
- a driving roller whose axis is fixed, a set of driving rollers mounted upon arms pivotally supported upon a rotatable shaft, and means adapted to permit a limited play of said arms and said rollers about said shaft.

MACHINE FORCIITTING- AND COLLAT ING PAPER.
V Specification of Letters Patent. I
Patented June e, 1916.
Application filed June 9, 1911. Serial No. 632,152.
To all whom '52! may concern:
Be it known that I, WILLIAM Y. DEAR, a citizen of the United States, residing in the city of Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Machines for Cutting and Collating Paper, of which the following is. a specification.
My invention relates to means for cutting large sheets of paper or other material into a plurality of smaller sheets, and then automatically gathering these smaller sheets into piles and folding them into form to be bound into books or pamphlets. I
My invention has particularly to do with a machine in which the original sheet is first perforated in parallel lines, then torn into a series of strips along these lines, these strips being piled and finally cut in a direction perpendicular to these lines and the small sheets thus formed collated and folded This operation is continuous and automatic from the time the sheet enters the machine until it is delivered in form ready for binding.
My improved device hasthe especial advantage of being free from tapes, which have been required in previous machines of like character and function. The tapes are extremely objectionable for the reason that they are subject to frequent derangement,
with the result that stock being fed through the machine is mutilated and damaged and the production of the machine decreased by the necessity for frequent stoppages for repairs. I have doneaway with the possibility of such trouble through the use of a 7 positive roller feed for the paper or other material being fed into the machine.
Inthe accompanying drawings which form a part of this specification, F igurel is a plan view of my improved machine; Fig. 2 is a side elevation; Fig. 3 is a sectional side view on line III-+111 of Fig. 1; Fig. 4: is a similar view .on line IVIV of Fig. 1; Fig. 5 is an enlarged sectional detail of the delivery and folding portions of the machine taken on line V-Vof Fig. 1; Fig. 6 is a vertical section on line VI-VI of Fig. 5; Fig. 7 is .a vertical sectional view of a modified form of folding apparatus; Fig. 8 is an elevation of F ig. 7; Fig. 9 is a detail view showing a portion of one of the feed roller arms; Fig. 10 is an elevation of a sheet of paper or other material after passing through the perforated rolls, the arrows indicating the two directions in which it progresses.
7 Referring now in detail to the drawings, the numeral 1 designates the framework of the machine in which is journaled a shaft 2 carrying a'plurality of circular disks 3 adjacent to the periphery of which is an inclined slide 4, at one side of which is an adjustable guide 5, having a guide surface 6 extending therefrom across the face of the slide. A shaft 7 extends eccentrically through these disks and is journaled in them. This shaft carries adjacent to each disk a gripper'8 secured to the shaft and rotatable therewith. These grippers are adapted to press against a series of pads 9 fixed to the faces of the disks when the shaft is rotated by means which will be described later. Secured to the shaft 7, adjacent to the first disk, is a crank 10, pivoted to which is an arm 11 passing through a guide block 12 on the surface of the disk.
The spring 13 is provided for causing this arm 11'to advance as far as it may into the block 12, thereby carrying with it the crank 10 and causing the grippers normally to press against the sockets .9. Secured to the shaft at either end are the trippe'r fingers 14 and 15, which are adapted to engage, respectively, the abutments 16 and 17 at defi- V nite periods in the rotation of the disks.
Supposing now a sheet of paper or other material to be fed upon the slide; its alinement being directed by the guides 5, it will pass beneath the guides 18 and beneath the tilting fingers 19 secured to the shaft 20, for at this instant the fingers 19 are lifted by the action of the cam 21, lifting theroller arm 22 secured to the shaft 20. The cam 21 is secured to the shaft 23' of spur gear 24:,
The guides 18 and their depending stops have been lifted a moment before by an exactly similar cam mechanism which it is not necessary to describe in detail. The paper now passing under the tilting fingers is clamped between the grippers 8 and their pads, one of the tripper fingers having engaged its abutment the instant before the paper arrived at this section of the disk, thus lifting the grippers and allowing the paper to pass under their ends. An instant later the tripper finger passed out of engagement with its abutment and the spring retracted the gripper against its pad, thereby clamping the paper tightly to the disks. As the latter continue to revolve the paper is perforated along a number of lines by means of the perforating rollers 26, the perforations on which enter grooves 27 in the disks. These perforating rollers are carried on a shaft 28 journaled in the frame and terminating in a gear 29 meshing with a large gear 30 upon the shaft 2. The continued rota tion of the disks carries the paper under the guide rollers 31 mounted upon the arms 32. The disks 3 are made of such size that their periphery is slightly greater in length than the longest length of paper to be used in the machine. Therefore, by the time the paper has passed beyond the rollers 31, but before it has passed the edge of the slide, its other end has left the slide and is wrapped about the disks 3. An instant later, through the action of the cam 21, the tilting fingers 19 are lowered into the position shown in Fig. 3, and at substantially the same instant, through the interaction of the second tripper finger with its abutment, the grippers 8 fly back from engagement with their pads and the front edge of the paper, thus released from the roller, passes between the stationary guides 33 and the tilting fingers, and continues in a straight line between the table bed 3% and the long horizontal guides 35 extending over the bed. As soon as the paper reaches the bed of the machine, and before its other end has left engagement with the rollers 31 and the disks, its front edge passes between the power-driven roller 36 and the rollers 37. The rollers 36, 38 and 39 each project slightly above the bed of the machine, are continuously rotated by means of a chain 40 passing over sprocket wheels in the ends of the respective shafts 41, 4:2 and 43, to which these rollers are secured, and the sprocket 44, power being applied to the shaft 73 carrying the spur gear 72 which meshes with gear 74 and drives the same, and which carries upon its extremities the fiy wheel i7 and pulley 4-8, by which power may be supplied to the machine. The rollers 37 are carried by arms 49 secured to the shaft 50 which is journaled in uprights 51 secured to the frame of the machine. The rotation of the power-driven rollers 36 and the idlers 37 resting thereupon will carry the 1 paper across the bed until the rollers 38 and their corresponding idlers 52 are encountered. These rollers, rotating at the same peripheral speed as the rollers 36 and 37, will continue to carry the paper smoothly across the bed until a similar pair of rollers 39 and their vertically disposed idlers 53 are reached, these latter in turn aiding in the passage of the paper smoothly and steadily across the bed plate. The paper will thus progress in a right-hand direction, as seen in Figs. 3 and 4, until the forward edge is a short distance from the guide 54, which bars its further progress. forward edge of the paper reaches this guide, however, the rear edge passes out of engagement with the rollers 36 and 37, and the rollers 52 and 53 are lifted from engagement with the power-driven rollers beneath them, the interval being such that the paper will smoothly come to rest through friction with the bed plate and will not bunch up against the guide. These rollers 52 and 53 are mounted, respectively, on arms 55 and 56 secured to shafts 57 and 58 extending over the bed plate and j ournaled in uprights ex tending above the main framework of the machine. To these shafts are also respectively secured cranks 59 and 60 joined by a link 61. Keyed to the end of the shaft 57 is a crank 62, pivoted to which is a link 63, the slotted end'of which, 6 embraces a shaft upon which is mounted a cam 66, against the surface of which contacts the roller 67 mounted upon the link 63. The shaft 65 is rotated by means of a spur gear 68 secured thereto which meshes with a gear 69 on a shaft 70, which in turn carries a gear 71 meshing with the gear 7 2 on the shaft 73, the gear 7 2 in turn meshing with the idler 7 4 upon the shaft 75, which meshes with the gear 30.
It will thus be seen that as the shaft 65 rotates and carries with it the cam 66, at a certain period in its cycle the link 63 will be caused to reciprocate, causing the rollers connected to its linkage alternately to engage and disengage with the continuously rotating power-driven rollers beneath them. The gearing which operates the shaft 65 is so proportioned that the cam 66 will make one revolution for one revolution of the main disks 3. By altering the position of the cam 66 upon the shaft 65 the exact moment when the rollers 52 and 53 release the paper may be adjusted with the utmost precision. The distance through which the paper will travel from the time the rollers are released until the edge reaches the guide will depend upon the speed with which the paper is propelled across the bed plate and the inertia of the paper consequent upon its velocity.
The rollers 52 and 53 are secured to the shafts 57 and 58 in such a Way that the utmost precision and speed of operation are Shortly before the obtained. This construction is illustrated in detail in Fig. 9, and while it will be described as applying to shaft 57, it is to be understood as applying equally well to shaft 58. Secured to the shaft 57 by means of a key 76, or in any other suitable manner, is a collar 77 carrying a pin 78. Capable of oscillation 0n the periphery of this collar 77 is a second collar 79 having a slot 80 therein for the accommodation of the pin 78 and wider than the pin. To the collar 79 is secured the'arm carrying the roller 52. It is practically impossible to keep the long shafts 57 and 58 rigid and true, and this construction permits a very quick rotation of the shafts,-so that, in spite of any warping, all the rollers take efiect at once without bruising the paper or racking the machine, the pressure between the rollers being due solely to gravity. This effect is of extreme importance since the rollers must seize the paper simultaneously and uniformly in order to carry it forward smoothly and in proper alinement.'
It will be noted according to this construction thatthe arm 55 is in constant engagement with the roller 52 during the time when it is lifted from the surface of the paper and when it is in positive driving engagement with the latter.
The paper 81, as it now lies upon the bed plate of the machine, is in the condition indicated in Fig. 10; that is, with parallel rows of perforations 82 passing completely across the face thereof in a direction parallel to its last motionacross the bed'plate. Immediately upon its coming to rest, one edge being accurately alined along the guide 54, the rollers 83 upon the shaft 84 are automatically lowered from the position shown in Fig. 2 until they contact with the constantly powerdriven rollers 85 beneath them. The rollers 85 are carried by the shaft 86, which bears at one extremity a beveled gear 87 meshing with a gear 88 upon the inclined shaft 89 carrying in its lower end a beveled gear 90 meshing with a beveled gear 91 upon the shaft 73. Since the shaft 73 is constantly rotated in the manner hitherto explained, the rollers 85 are also constantly rotated at uniform speed. The mechanism for causing the rollers 83 to contact with the rollers 85 includes the cranks 92 keyed to the shaft 93, which is caused to oscillate by means of the arm 94, link 95, lever 96, pivoted at 97 and carrying at its lower end a roller 98 which bears against the face of a cam 99 secured to the shaft 65. Rotation of this cam will cause the lever 96 to be shifted in its position and the throw of the cam is made suflicient to cause the rollers 83 to contact with the rollers 85, the cam 99 being so adjusted with relation to the shaft 65 that this operation occurs synchronously with the coming to rest of the means of the beveled gears 109 and 110,
the shaft 108 being carried by brackets 111 and 112 extending fromv the framework of the machine.
The rollerslOO and 101 are equal in size and are rotated at the same peripheral speed as the roller 85, so that the paper is" smoothly carried under the guide 113 into engagement with the tworollers 114 and 115, whose axes are parallel to the axes of the rollers 100 and 101. The roller 114 is an idler, the shaft 116 of which rotates in a slot 117 in a skeleton structure 118 extending acrossthe edge of the bed plate. The roller 115 is power-driven by means of a chain 119, which passes over the sprocket 105 and idler 120. This roller therefore revolves at the same peripheral speed as rollers 100 and 101 and the paper continues its even course between therollers 114 and 115, after leaving which it passes between another set of rollers 121 and 122'. The rollers 121 are driven from the shaft 108 by means of the beveled gears 123 and 124. It is to be noted, however, that the gear '124 is substantially larger in diameter than gears 107 and 109, and that gear 123 is correspondingly smaller than gears 106 and 110, with the result that the rollers 121 and 122 which are geared together by means of the gears 125 and 126, have a substantially greater peripheral speed than the rollers, which have hitherto been in engagement with the paper.
The result is indicated in Fig. 5, where, at 127, it is seen that the paper has parted along one of the lines of perforation. .It will readily be seen that the greater peripheral speed of the last set of rollers caused a considerable tension in the paper and the friction between the rollers and the paper is sufficient to create a'tension great enough to break the paper along the lines of perforation. The machine is preferably so designed that this tearing effect will take place between the last set of rollers and rollers 114 and 115. There is thus produced a strip of paper equal in width vto the distance between the lines of perforation. As the rollers 121 and 122 continue to revolve, this strip of paper is carried forward between the guides 113 and the bed plate until it is deflected from its course by means of the rollers 128 and 129, the line of centers of which is inclined to the vertical, as indicated most clearly in Fig. 5. Rollers 129 are positively driven from the rollers 122 by means of gears 130 and 131. Rollers 128 are idlers mounted upon arms 132 depending from a stationary shaft 133. The peripheral speed of rollers 129 is the same as that of rollers 121 and 122, so. that the paper is now carried forward without tension. A novel result,-however, is accomplished by inclining the line of centers of the two sets of rollers 128 and 129. The end of the paper is deflected downward,as indicated at 134. Striking a new bed plate 135 at a lower elevation, the paper slides along it, but there is a torsion produced in the paper, since the propelling influence is not now in the line of its motion. The forward edge of the paper continues under the guide 136 until it reaches the stop 137. The distance between the stop and the lastmentioned rollers is greater than the width of a strip, and therefore the rear edge of the strip of paper has passed between the rollers 128 and 129 by the time its forward edge reaches the stop 137. Owing to the torsion in the paper, the rear edge is flipped down upon the bed plate and lies smoothly thereon, making way for the forward edge of the next strip to pass across and above it. This flipping action is highly important when the machine is running at high speeds, as it automatically causes the paper to lie flat upon the bed plate in a much shorter interval of time than would be possible if gravity alone were relied upon to accomplish the same result, and absolutely prevents conflict between the rear edge of the strip of paperwhich has just passed through rollers 128 and 129 and the forward edge of the next strip which succeeds it in a very short interval of time. As each strip emerges from between the rollers 128 and 129, the strip is induced to aline itself evenly along the guide or stop 137 by means of the flipper wheel 138, which is mounted on a shaft 139 carried by a bracket 140 secured to the framework of the machine. A belt 141 passes over pulley wheel 142 on the shaft 139, over guide wheel 143 and the pulley 144 carried on the end of the shaft 108. The flipper wheel consists of a hub 145, to which is secured a plurality of resilient members 146 radially disposed about the periphery of the hub. These members are preferably made of felt, leather or some other pliable material, and the function of the flipper wheel, which revolves in the direction indicated by the arrow in Fig. 2,
is to promote the even piling of the strips,
as already indicated.
The entire sheet of paper is subjected to this same operation; that is, it is separated along the lines of perforation into strips,
which are successively piled upon each other against the stop 137.
When the last strip has fallen into place, the stop is automatically lifted by the rotation of the arms 147 about their shaft 148. This is accomplished by the action of the arm 149 secured to the said shaft and the link 150 pivoted to this arm. The lower end of the link is fashioned into a slotted member 151 embracing the shaft 152, which is rotated from the shaft 65 by means of beveled gears 153. The shaft 152 has secured thereto a cylindrical cam 154 engaging the surface of which is a roller 155 mounted on the side of the link 150. When the portion of the face of this cam of lesser radius contacts with the roller, the link 150 will descend, rotating the shaft 148 and thus lift ing the stop 137. The arms 147 are preferably made adjustable, having the slots 156 through which protrude nuts 157, so that the arm may be clamped in a variety of po sitions with respect to the carriage 158, and thus accommodate various widths of strips of paper, the maXiInum width being sub stantially that provided for by the adjustment shown in Fig. 5.
Immediately upon the stop 137 being lifted, the fingers 159 are forced longitudinally along the slots 160 in the bed plate by the bar 161, to which they are secured. Weights 162 attached to the ends of cords 163 passing over the pulleys 164 are secured to the bar 161. These weights impel the bar toward the pulleys 164 when the roller 165 secured to the end of the lever 301 enters a cam 300, secured to shaft 152, the arms 166 secured to shaft 167, to which lever 301 is also secured, and being connected to the bar 161 by means of links 168. The passage of the fingers 159 through the slots carries the pile of strips of paper across the bed plate and into engagement with the rotary knives 169 and 170, the paper pass ing beneath the guides 136. These knives are mounted, respectively, on the shafts 171 and 172 carrying the gears 173 and 174 meshing with each other. The gear 174 is positively driven through the idlers 17 5. 176 and 177 from the gear 125 on the shaft of the roller 121. The shaft 171 is carried in bearings 178 and 179. The pressure between the rotary knives may be adiusted by compressing the springs 180 through the tightening of the bolts 181, the bearings being slidable vertically in the blocks 182 and, 183; As the paper passes between these rotary knives it is out in lines parallel to the direction of its motion and at the same time carried forward until it encounters the positively driven rollers 184 and the idle rollers 185 secured to the arms 186 depending from the shaft 187 secured to the framework of the machine.
As the paper continues onits course it passes across the face of the roller 188, which carries the gear 189 meshing with the gear 190 on the shaft of the roller 184. Rollers 184 and 188 therefore rotate in opposite directions. Roller 188 is driven through beveled gears 191 and 192, the latter being mounted on the shaft 193 which is positively driven from the shaft 172 by means of sprocket wheel 194 and chain 195. The cut piles of paper thus eventually pass underneath the guides 196 and come to rest against the stop 197, to which the guides are secured. At this juncture the tucker blade 198 carried by the curved levers 199 which are pivoted to the shaft 200 descends between the rollers 184 and 188, carries the paper between these rollers, which rotate in opposite directions and therefore facilitate this operation, and the paper passes between the guides 201 and 202 into the box-like structure 203, this operation being illustrated in 5.
The extremity of one of the curved levers 199, remote from the blade 198, is pivoted to a link 204, the end of which is slotted at 205 and embraces the shaft 152. The roller 206 mounted upon this link contacts with the surface of the cylindrical cam 207. When the portion of maximum radius 208 of this cam engages the roller it forces the link radially away from the axis of the cam, thereby causing the blade 198 to descend, as already described, the position of the cam upon the shaft 152 being adjusted to bring about this result at the proper instant already indicated.
Immediately after the folded paper has descended into the box 203, the cross-head 209, operating in slot 210 in the opposite walls of the box 203, advances in a righthand direction with relation to Fig. 5, causing the folded paper to move laterally in the direction of the arrow until it is brought to rest, still in an upright position, against the buffer weight 211. The cross-head 209 is secured to an arm 212 which is connected by 1 means of the link 213 to a lever 214 pivoted at 215 to a shaftjournaled in the main frame. The lower extremity of this lever is pivoted at 216 to a link 217, the end of which is slotted at 218, and embraces the shaft 152. The link 217 carries near its lower extremity aroller 219 which contacts with the surface of a cylindrical cam 220 keyed to the sllaft 152. As the portion of this cam of shorter radius engages the roller 219, the link 217 will move toward the axis of the cam, thereby oscillating the lever 214 and causing the cross-head to advance within its slot through the agency of the link 213. Succeeding piles of paper will pass through the same operation, being stacked up as indicated at 221 in Fig. 5. When the requisite number forming a complete book or pamphlet has been collected in the box 203, they may readily be lifted out and are then ready for the bindery. These sheets are maintained in an upright position in the box 203 partly through engagement at one side with the buffer 211 and at the other with the abutment 222 and the lower portion of the guide 202. i
Referring now to Figs. 7 and 8, it will be seen that they illustrate a modification, the purpose of which is to provide a machine in which the piles of paper, as they are delivered from the rotary knives, are folded in a direction parallel to their motion instead of perpendicular thereto, as was the casein the mechanism just described. The modification illustrated in these figures is an alternative for the folding mechanism previously described and is so designed that it may replace the other in the machine without requiring any considerable structural changes therein. The parts which remam unchanged are therefore given the same numerals in these figures as in Figs. 1 to 6, inclusive.
The operation of the machine and the functions of the various parts are identical with those of the machine previously described, up to and including the rollers 184 and 185, and therefore the description of these parts will not be repeated. I In the modification, however, the unitary roller 184 is replaced with a plurality of rollers 225 which are constantly rotated from gears 226 on the shaft 193 by means of the chains 227 and gears 228 secured to the shafts of these individual rollers. The function of the individual rollers, however, remains the same as that of the single roller 184 hitherto described, and the change is made merely to accommmodate the other structural alterations made necessary by the alternative construction.
. Immediately upon the piles of strips reaching the stop 229, the blades 230, which, together with the curved levers 231', replace the blade 198 and the curved levers 199, descend between the pairs of rollers 232 and 233, being actuated by the same mechanism which caused the curved levers 199 to oscillate about the shaft 200. The rollers 232 and 233 are rotated in opposite directions, that is, toward each other, the rollers 232 being driven from the shaft 193 by means of the beveledgears 234, and the rollers 233 being driven from the rollers 232 by means of the chain drive 235. The paper progresses downward in substantially the same manner as before into a receiving box 236 which has replaced the box 203 upon the shelf 237. This box has a curved side 238 formed in the arc of a circle whose center is located in the axis of the shaft 239, which is rotatably mounted in a sleeve 240 forming an extension of the box 236. Fastened to the upper end of the shaft 239 is a wing 241 which normally has the position indicated in Figs. 7 and 8. As soon as a folded pile of papers has entered the box 236, however,
the box structure into the position indicated at 242 in Fig. 8. To the lower extremity of the shaft 239 is secured an arm 243, from one end of which projects a pin 244 having a ball joint 245 entering a socket in the extremity of a link 246 which is pivoted to the lower end of a lever 247, the upper end of which is pivoted to the frame at 215. The link 217 causes the oscillation of the lever 247 in the same manner in which it did the oscillation of the lever 214 in the first modification described, one end of a spring 248 being attached to the lever at 249, the other end being secured to the framework of the machine at 250 for insuring the constant engagement of its cam with the roller 219 on the end of the link 217. Ihe movement of this lever 247 causes the rotation of the arm 243 and therefore of the shaft 239 to which it is secured, and effects the piling of successive folded piles of paper into the position indicated at 242 in Fig. 8. The extremity of the arm 243 opposite to the pin 244 carries a second pin 251, to which is pivoted a link 252 for actuating the other two Wings 241, the movement of the three therefore being simultaneous. It will thus be seen that the continuous operation of the machine results in the collecting of threesets of folded piles of paper at the delivery end of the machine, the principal difference in the operation of this modification from that first described being the direction in which the paper is folded.
