Referring more in detail to the drawings:--

1 and 2 designate respectively the right and left side frames oithe machine, each includin substantially rectangular-shaped end sections 3 and 4 connected by upper and lower side bars 5-5 and 6-6 ztending longitudinally of the frame in spaced relation as best illustrated in Fig. l. The end sections 3 and 4 are preferably provided with inwardly projecting base flanges '2 arranged for support on suitable rectangularshaped base members 8 and 9.

Supported upon upwardly extending inset por tions 10 of the end sections are spaced bed plates 11 and 12 connected at their rear ends by a curved plate 13 and at a point intermediate their length Gill Hill

by a vertically arranged cross plate 14 (Figs. 1 and 2). The end sections 4 are also interconnected by a vertically arranged plate 15 extending therebetween and connecting their front edges as illustrated in Fig. 2.

The various parts composing the frame-work of the machine as just described are secured together by suitable bolts or similar fastening devices 16 to provide a rigid structure.

Rotatably mounted in suitable bearings 17 in the side sections 4 and in adjustable bearings 18 slidably mounted in slotted openings 19 in the side sections 3 are spaced cross shafts 20 and 21 respectively for supporting a paper-carrying conveyor generally designated 22. The conveyor 22 includes spaced pairs of aligned sprockets 2324 and 25-26 fixed to the shafts adjacent the inner face of the respective end sections of the side frames.

Operating over the aligned sprockets are endless chain belts 2'7 and 28 having their upper runs operating adjacent the lower side edge of the upper longitudinal bars 5 and 5' and their lower runs operating adjacent the lower bars 66' (Figs. 2 and 3). Fixed to selected links 29 of the respective chains at spaced points along their lengths are brackets 30 carrying paper-conveying pocket members 31 that extend between the chains and which are movable thereby to collect the component sections of a newspaper as later described.

In order to operate the conveyor, the shaft 18 is provided with a gear wheel 32 which is driven through an idler gear 33 meshing therewith and rotatably mounted on a spindle 34 projecting from the end section 4 of the side frame 2 (Fig. 2) The idler gear 33 is driven by a pinion 35 fixed on a counter shaft 36 having one end rotatably mounted in a bearing 37 provided in the end section 4 of the side frame 2 and its other-end in an aligning bearing 38 carried by a bracket 39 supported from the outer face of the end section 4 as illustrated in Figs. 1 and 3.

Fixed on the shaft 36 is abevel gear 40 meshing with a bevel pinion 41 carried on the lower end of a vertically arranged shaft 42, the shaft 42 being rotatably mounted in a vertical bearing 43 also fixed to the outer side face of the section 4 directly above the bracket 39. Fixed on the upper end of the shaft 42 is a bevel gear 44 meshing with a similar bevel gear 45 on a horizontally arranged line shaft 46. The shaft 46 extends longitudinally of the machine alongside the bed plate 12 and is rotatably supported at spaced intervals along its length by bearings 4'7 carried on brackets 48 fixed to the outer side of the bed plate. The shaft 46 carries a bevel gear 49 at its opposite end which meshes with a bevel gear 50 on a cross shaft 51 rotatably mounted in the bed plates 11 and 12.

The shaft 51 carries a. sprocket 52 which is actuated from a sprocket 53 fixed to a counter shaft 54 rotatably mounted in extensions 55 of the end sections 3, the sprocket 52 being actuated by a chain 56 operating over the respective sprockets. Thev sprocket 52 is normally free on the shaft 51 but is adapted to be operably connected therewith by a suitable clutch mechanism indicated at 5'7 and which is operable by mounted in the end extensions 55. The shaft 62 carries a fixed sprocket 63 which is driven by a chain 64 operating thereover and over a sprocket 65 on the armature shaft 67 of a suitable motor 68.

The respective sections of the newspapers to be assembled are arranged in individual stacks as designated 69, '70, and 71 and which may include comic, news and society sections, respectively, that are to be assembled with the society and news sections received in the fold of the comic section. The stacks are carried in spaced relation between the bed plates 11 and 12 on horizontally arranged plates 72, '73 and '74 in position to be engaged by withdrawing mechanism for successively moving the sections in the respective stacks for delivery into the paper carrying pocket members of the conveyor as they pass below the respective stacks. Each stack of paper sections is supported between fixed guides 77 and 78 and movable guides 79 and 80 carried on the plates previously described so that the folded edges 81 thereof overlap the front edges 82 of the plates to provide room for engagement of the withdrawing mechanism therewith as now to be described. The withdrawing mechanism for each stack is identical to the other and, therefore, only one of them will be described in detail.

The bed plates 1112 are preferably built in sections, each having an upwardly extending portion located at a point adjacent each stack to form a support for vertically spaced cross shafts 84 and 85 which carry the fixed guide members '77 and 78 previously mentioned. The guide members 77 and 78 include blocks 86 having spaced apertures 87 and 88 to receive the shafts 84 and 85, respectively. Fixed to the upper face of the blocks are bars 89 having downwardly extending ends 90 spaced from the blocks 77 to provide room therebetween for brackets 91 which are carried by the depending portions of the bars.

Pivoted to the brackets 91 on pins 92 are depending arms 93 having forwardly projecting wedge-shaped fingers 94 on their lower ends which are operable through slots 95 formed in the depending portions 90 of the bars to engage between the sections of the newspaper supported in the stack. The fingers 94 are normally retained in retracted position and from engagement with the stack by flat springs 96 having one end fixed to the bolt 97 which attaches the bracket members 91 and having depending curved ends 98 pressing against the face of the arms 93 to hold the fingers in retracted position.

Fixed on the lower shaft 85 are spaced arms 99, 100 and 101, each having forwardly projecting ends 102 arranged to normally engage and support the overhanging portion of the stack to prevent the sections from drooping over the front edge of the plates '72, '73 or 74.

The shaft 85 is rocked to swing the arms to and from supporting position by a cam disk 103 fixed to a rotatable shaft 104 mounted in the bed plates 11 and 12 at a point directly below the shafts 84 and 85. The cam disk 103 has a peripheral cam track 105 having a high lobe portion 106 and a low lobe portion 107 for engaging a roller 108 fixed to a rocker arm 109. The rocker arm 109 has its lower end pivotally supported on the stud 110 projecting from the bed plate and has its upper end terminating at a point above the shaft 85 to connect with a rocker arm 85' thereon by a link 111.

In order to retain the roller 109 in contact with the cam disk 103, I provide the shaft 85 noensoo with a coil spring 112 having one end engaging a collar 113 on the shaft and its opposite end engaging a boss 11 1 projecting from the inner face of the bed plate 12 as best illustrated in Fig. 3, the spring being so tensioned as to move the shaft in a clockwise direction (Fig. 4) so that when the roller 108 engages the high lobe portion of the cam disk the shaft is rocked in an anti-clockwise direction against tension of the spring to bring the supporting finger into position for supporting the projecting edge of the stack, and when the low lobe portion of the cam disk engages the roller 108 the spring 112 will rotate the shaft in a clockwise direction to move the arms from engagement with the bottom of the stack. When this occurs, the fingers 9 1 are projected toward the stack to support it when the arms 102 are moved out of functional position.

In order to actuate the fingers 94, the shaft 104 is provided with a second cam disk 115 of slightly smaller diameter than the disk 103 and having a high lobe portion 116 and a low lobe portion 117 for engaging a roller 118 on a depending arm 119 of a rock shaft 120 rotatably mounted in the bed plates. The rock shaft carries upwardly extending arms 121 and 122 located in alignment with the guide members '77 and '78 for engaging pins 123 projecting rearwardly from the arms 93 and slidable through openings 124; formed in the blocks 86 at a point between the shaft 8 1 and 85. Sleeved on the pins and having one end engaging against the arms 121 and their opposite ends against the blocks 86 are springs 125 for retaining the roller 118 in engagement with its cam disk 115. It is thus apparent that when the roller engages the high portion of the cam the pins are moved forwardly through the books to move the fingers 9 1 into engagement with the lowermost section in the stack to support the free edge of the stack when the arms 102 are moved out of position as later described.

Fixed on the shaft 84 adjacent the guide members '7'7 and '78 are downwardly and forwardly curved arms 126, 127 and 128 terminating in upwardly extending ends 129 (Figs. 1, 16 and 1'7) to pivotally mount vacuum nozzles 130. The arms 126, 127 and 128 are hollow to provide the channels 131 having their upper ends communicating with openings 132 in the shaft 8 1, the shaft 84 being tubular to provide means through which a vacuum is drawn in the channels 131 of the arms to effect operation of the vacuum nozzles as later described.

The arms are clamped to the shaft 84 so that the openings 132 are in communication with the channels 131 by a clamping cap 133 extending over the shaft and fixed to the upper ends of the arms by screws 134 extending through ears 135 on the caps and through ears 136 in the upper ends of the arms as best ilustrated in Fig. 1'7. The free ends 129 ofthe arms are provided with a forwardly extending stop member 137 having a fiat upper face 138 to engage against the bottom of the stack. Projecting rearwardly from the stop member 137 are spaced ears 139 and 140 between which is pivoted the vacuum nozzles previously mentioned. The vacuum nozzles are mounted on a tubular pin 141 having closed ends and which extends through the ears 139 and 110 and through an ear 142 on a tubular support 144 for slidably carrying the vacuum nozzle.

The tubular pin 141 is provided with arcuate-' shaped openings 145 communicating with the channel 130 through branches 146 and 147 that are provided in the ears 139 and 140 as best illustrated in Figs. 16 and 18. The tubular pin 1 11 is also provided with an opening 148 communicating with a channel 149 in the ear 1 12 of the tubular support 1 14.

The vacuum nozzle 130 is telescopingly mounted within the support 14 1 and includes a relatively flat head portion 150 having an upwardly opening mouth 151 adapted to engage the lowermost section in the stack when in the position illustrated in Fig. 5.

The head 150 carries a tubular neck 152 which is slidably retained in the sleeve support 1 .4. by a pin 153 carried by the neck portion and operable in a slot 154 formed in the sleeve support 1 1 1. The nozzles are retained in extended position by coil springs 155 having one end engaging against the end of the neck and its opposite end against a seat 156 formed in the support 1%. In order to actuate the nozzles on their pivotal sup ports the projecting ends 157 of the tubular pins 14.1 are provided with lever arms 158 (Figs. 4

and 18).

The arms 158 have slotted ends 159 to engage pins 160 carried in the slotted ends of actuated rods 161 so that the arms may move in an are as the rods reciprocate in a straight line. The actuating rods 161 are operable under influence of the vacuum created in the arms by means of pistons 162 fixed to the inner ends of the actuating rods, the pistons being slidably mounted in cylinders 163 pressed into tubular bosses 165 formed on the arm intermediate its ends. The piston rods are slidable through bearings 166 in the forward ends of the cylinders and are retained in retracted position by springs 167 having one end bearing against the piston and. their opposite ends against the forward ends of the cylinders. The cylinders are open to communication with the vacuum channels 131 in the arms through port 163.

It is thus apparent that when a vacuum is created in the arms a vacuum is drawn in the cylinders through the ports 168 to move the pistons against tension of the springs 167 to rock the arms 158 in an anti-clockwise direction (Fig. 6) for moving the nozzles away from the stack to carry the lowermost section therewith since the vacuum is simultaneously drawn through the nozzles. The movement of the nozzles in a downward direction responsive to movement of the pistons 162 carries the folded edge of the lowermost section in the stack into position to be engaged between pairs of withdrawing disks 169 and 170, the remainder of the stack being supported by the fingers 9d and the stop members 137, while the arms 93, 100 and 101 are being returned to stack-supporting position. The members 169 are preferably segmental in order to allow the edge of the sheet to drop into position to be engaged by the arcuate portion 1'71 of the disks which, cooperating with the full cirdrawal from the stack. The disks 170 are mounted on a shaft 1'72 extending across the bed plates cular disks 1'70, feed it downwardly for withr in spaced relation with the shaft 104: carrying the I segmental disks.

Positioned below the withdrawing disks are pairs of rollers 1'74 and 1'75 rotatably mounted on shafts 1'76 and 177 carried in bearings 178 projecting from the lower edges of the bed plates with a bevel gear 179 meshing with a bevel gear 180 on the shaft 46 previously described. Fixed on the shaft 104 adjacent the gear 179 is an eccentric disk 181 for operating a pitman 182 having its upper end connected to a wrist pin 183 on an oscillating cam 184. The cam 184 has a cam track 186 for engaging a roller 187 on an arm 188 fixed to a projecting end of the shaft 84 to effect operation of the nozzle carrying arms 126, 127 and 128, the roller being retained against the cam by coil springs 189 sleeved on the shaft 84 and having one end engaged in a boss 190 on the bed plate and its opposite end fixed to a collar 191 carried by a sleeve 192 also sleeved on the shaft.

It is thus apparent that when the roller 187 engages the low lobe portion 193 of the cam disk 184, the shaft 84 is moved in a clockwise direction (Fig. 5) by the spring 189 to move the nozzles out of engagement with the stack.

The shaft 176 for the roller 174 is driven from the cam shaft 104 by a chain 195 running over sprockets 196 and 197 on the respective shafts (see Fig. 19).

In order to create a vacuum in the respective nozzles. I provide a vacuum pump 198 carried on a shelf 199 fixed to the extensions of the end sections 3 as best illustrated in Fig. 1, the vacuum pump being driven from the shaft 54 by a-chain 200 operating over a sprocket 201 on the shaft 54 and over a sprocket 202 fixed to the pump shaft 203. The inlet 204 of the pump is connected by a pipe 205 with a rotary control valve 206 (Figs. 1 and 14). The control valve includes a cylindrical housing 207 having a hollow sleeve valve 208 rotatably mounted-in the .housing to establish communication with branch pipes 209, 210 and 211 connected with the tubular shafts 84 of the respective heads, the sleeved valve being provided at suitable intervals around its periphery with ports 212 to establish communication with the pipe 205 leading from the pump and communicating through an open end 213 of the rotary valve.

The valve 208 is actuated by a pinion 214 meshing with a drive pinion 215 fixed on the shaft 46 (Fig. 1). It is thus apparent that the vacuum to the nozzles of the respective heads is controlled in timed relation so that the sections are delivered to the paper-carrying pockets at the proper time.

The brackets 30 include depending channelshaped end members 216 having their flanges 217 connected by spaced plates 218 extending between aligning brackets on the respective chains. Fixed to the lower ends of the channel members 216 are trough-shaped bottoms 219 connected to the plates 218 by straps 220 at points intermediate their length to form a pocket 221 into which the paper sections are delivered from the stacks supported on the plates 72, 73 and 74. The brackets 30 carry heads 222 provided with spaced bearing openings 223 and 224 in which are rotatably mounted spaced shafts 225 and 226 having their axes located substantially in the plane of the plates 218.

Hinged to the shafts 225 and 226 are upwardly extending wings 227 and 228 forming upward extensions of the pockets 221, the wings being provided with ears 229 having sleeves 230 which are fixed on the shafts 225 and 226 as best illustrated in Fig. 10. The shafts are actuated to move the wings 227 and 228 toward and away from each other by intermeshing gear segments 231 and 232 fixed to the ends of the shaft adjacent the side rail 5. Each gear segment 232 is provided with an arm' 233 having a roller 234 operating in a camgroove 235 formed in the inner face of the rail 5' and which is provided with a high cam portion 236 between the positions of the first and second stacks over which the roller 234 moves to effect operation of the gear segments and movement of the wings 227 and 228 to close on the paper section delivered into the pocket as later described.

The wings 227 and 228 are provided with openings 237 adjacent the upper corners thereof as best illustrated in Fig. 9, and secured to the wings in alignment with the openings are vacuum nozzle arms 238 and 239 fixed to the ends of the shafts 225 and 226 at the ends opposite to the gear segments previously described. The ends of the shafts carrying the vacuum nozzles are counterbored as at 240 and the counterbores communicate with the interior of the nozzles through ports 241. The open ends 242 of the counterbores communicate with channels 243 provided in plates 244 fixed to the heads 222 by bolts 245.

The plates 244 are provided with bushings 246 extending therefrom at a point above the chains to carry vacuum shoes 247. The vacuum shoes 247 slide along the side face of the rail 5 at the right hand side of the machine (Fig. 1) and communicate with an interior channel 248 formed 5 therein, through a port 249, located directly below the first stack of sections. In order to retain the shoes in close sliding engagement with the rail 5, the shoes are provided with tubular collars 250 telescoped over the outer ends of the 0 bushings 246, and sleeved thereover are coil springs 251 having one end engaging the plates 244 and their opposite ends engaging against the shoes (Fig. 9). The interior channel 248 of the rail is in communication with the vacuum line 5 205 through a T-fitting 252 having a nipple 253 threaded into an opening 254 formed 'in the rail.

In order to retain the flap of the first section deposited in the pockets against the wings 228 after they have been separated by the vacuum nozzles, the wings are provided with slide bars 255 having slots 256 through which headed pins 257 project to retain the slide bars on the wings as best illustrated in Fig. 12. The outer ends of the slide bars are provided with a ball bearing 258 which engages a cam track 259 formed on the inner face of the rail-5 directly above the shoes to effect movement of the slide bar on the wings as the conveyor moves the carriers along underneath the stacks of paper sections. The ends of the slide bars are provided with hook-shaped members 260 arranged to extend over the flaps of the paper sections to retain them against the side wings.

In order to retain the slide bars in engagement with the cam track, I provide springs 261 having one end fixed to pins 262 carried on the inner ends of the slide bars and their opposite Mt ends fixed to pins 263 carried by .the ear 229 (Fig. 12).

In operating a machine constructed and assembled as described, stacks of the respective sections of a newspaper are placed in their respective heads where they are supported on the plates 72, 73 and 74, as, for example, a stack of the comic sections is placed on the plate 72, the news section on the plate 73, and the society section on the plate 74.

noe noo The vacuum nozzles 130, the arms 99, 100 and 101, and fingers 9e are adjusted to engage the overlapping portions of the bottom paper sections in the respective stacks. The other adjustments, including moving of the guides 79 and into engagement with the sides of the stack, are made and the machine is started to operate the con- -veyor and the withdrawing mechanisms or the respective heads to successively remove the lowerrnost sectionsin the stack and to deposit them into the pockets of the carriers as they pass along their path. of travel below the stacks. For example, folded edge portions of the comic sections in the stack 69 are normally supported on the arms 99, and 101, and the finger 94 is in retracted position. The eccentric 181, through the cam 13s, effects reciting movement of the vacuum nozzles for that stack into engagement with the lowermost comic section, as illustrated in Fig. 5. The vacuum control valve is then in position to effect a vacuum through the nozzles to engage the lowermost section in the stack. At this time the cam 103 moves into position for actuating the lever arm 109 to rock the arms 99, 100 and 101 out of supporting position relatively to the stack.

The fingers 94: then move into position for supporting the remaining sections as illustrated in Fig. 6.

When the vacuum is drawn in the arms 128, the pistons 162 are actuated against tension of the springs 167 to swing the vacuum nozzles downwardly into the position as shown in Fig. 7, drawing the fold of the lowermost section in the stack into position to be engaged by the segmental roller 169. The vacuum control valve then shuts ofi the vacuum to release the folded section of the paper which droops between the roller segments and the rollers 170. At this point the cams 115 and 103 move into position to allow the arms 99, 100 and 101 to re-engage the bottom of the stack and the fingers 94 to be disengaged from the stack, after which the arms 126, 127 and 128 are returned to their retractive position. The arcuate portions of the segmental disks then move into engagement with the fold to move the section downwardly through the rollers 17% and 175 to withdraw the section from the stack.

Rotation of the rollers 174 and 175 feeds the withdrawn section into one of the pockets of the conveyor which has moved into position under the stack. The roller for that pocket is then operating in the low portion of the cam track 235 and the wings are in open position to receive the section. As the pocket carrying the section continues'along the rails, the roller engages the high portion 236 of the track 235 to swing the wings inwardly to engage the opposite sides of the section. At this point the shoe on that pocket registers with the opening 249 and the vacuum is drawn through the nozzles 238 and 239 to draw the flaps of the section against the wings.

As soon as the roller 234 moves oh the high portion of the cam track, the wings svsfmg to open position, opening the flaps of the section. At this time the slide bar 255 for that pocket engages the high portion of the cam. track 259 to move the holding finger 260 over the opened flap of the section resting against the wing 228 to retain the sections open after the vacuum to the nozzles 238 and 239 is broken. As the pocket carrying the opened section passes under the remaining heads, the news section and the society section are deposited within the open flaps of the first section.

As the pockets carrying the assembled sections move through the are formed by the sprockets 2d of the conveyor, the sections drop by gravity onto a delivery belt 26% and onto a stack table 265 (Fig. 1). The belt 264 preferably operates at a faster speed than the speed of the assembling conveyor to space the deposited sections on the belt 26%. The belt 264 operates on rollers 266 and 267 rotatably mounted on the base 9 and in brackets 268 projecting from the end of the machine.
