United States PatentO COLLATING MACHINE Alwyn R. Bunting, 214 80th St., Virginia Beach, Va.

Filed May 22, 1959, Ser. No. 815,236

24 Claims. (Cl. 27058) (Granted under Title 35, US. Code (1952), see. 266) The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalities thereon or therefor.

This invention relates to a collating machine and more particularly to a machine for collating a plurality of sets of paper at one time.

In accordance with prior art practice, collator machines are generally adapted to collate or collect, only one set of sheets or papers at a time, as for example several sequentially arranged mimeographed sheets, and therefore require the removal of a completed set from a collection basket or the like prior to assembling together of a subsequent set of papers. In addition, prior art devices frequently make use of air pressure or suction means for sequentially removing sheets from a stack prior to feeding to a collection basket, which naturally requires a source of air pressure or vacuum, the need for which is eliminated in the instant invention. Furthermore, most prior art devices are extremely complicated and expensive to construct, particularly where the machine is adapted for automatic collation without the aid of hand feeding methods.

In accordance with the instant invention, the collator comprises a rotary ferris-wheel-like drum including a plurality of trays, each of which is adapted to hold a stack of sheets of the same page number. For example, the trays are numbered, and respectively contain a plurality of pages 1, pages 2, pages 3, etc. which are adapted to be assembled together to form a set of mimeographed or printed sheets where in each set, the pages are sequentially arranged. The instant apparatus includes a means for feeding the aforementioned stacked sheets sequentially to a plurality of collecting baskets in such a manner that the sheets are sequentially fed into each of the baskets so as to form a number of sets of sequentially arranged pages corresponding to the number of collection baskets utilized. The collection baskets are arranged to move transversely of the trays in such manner that the sheets are sequentially fed from the trays into the baskets so that a plurality of sets are collected in the baskets, one set per basket. It is pointed out that certain of the trays may contain colored separation sheets so that the machine may be operated continually whereby more than one set may be collected in each basket. Thus the instant invention, unlike the prior art collator machines, is adapted to collate and collect several sets of sheets rather than only one set. in addition, the instant apparatus is relatively simple in construction and fool proof in operation, being comparativelyIihbxpensive to construct, operate and maintain; in addition to which, the instant apparatus does not require the use of an air pressure or vacuum means to separate the sheets in the trays prior to feeding into the collection baskets.

It is accordingly an object of this invention to provide a collator machine adapted to overcome the inherent disadvantages found in the prior art.

2,952,456 Patented Sept. 13, 1960 Another object of this invention is to provide a new and improved collating machine having means for simultaneously collating and collecting a plurality of sets of sequentially numbered sheets of paper.

Still another object of this invention. is to provide a new and improved collating machine adapted to simultaneously collate and store a plurality of identical sets of sequentially numbered sheets of paper at one time.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:

Referring now to the drawings wherein like reference characters designate like or corresponding parts throughout the several views, there is shown in Fig. 1 an elevational view of the overall structure of a collator .20 constructed in accordance with the instant invention. The collator 20 includes a main input drive shaft 22 having double-lead-screw threads cut in its surface. The shaft 22 is rotatably mounted at its opposite ends in a pair of bearings 24 and 26, and is located beneath a horizontal platform 28 which has a pair of tracks 30 fixedly mounted thereon, A carriage 32 is slidably mounted on the tracks 30 and is reciprocably driven, through a connection hereinafter described, by the double lead-screw 22. The carriage 32 has an open top container 34 reciprocably mounted on its upper surface, said container 34 having a pair of dovetail tongues 36 in slidable connection with like shaped grooves in the upper surface of the carriage 32. It is pointed out that the container 34 is divided in four compartments 35 in. the instant embodiment of the invention, said compartments being designatedjin the drawings by the letters A, B, C and D.

The carriage 32 and container 34 are adapted to move past a rotatable, ferris-wheel-like drum 38 having circumferentially mounted thereon a plurality of platforms 40 each of which is divided into compartmentsor trays 42 equal in number to the number of compartments 35, and each is adapted to hold a stack of sheets of paper. In a manner hereinafter described, the circumferentially spaced platforms 40 are held in a horizontal plane at all times during rotation of the drum 38. Each platform 40 temporarily comes to rest in a position juxtaposed with the upper edge of the movable container 34 so that individual sheets of paper may be fed from the trays 42 intoa plurality of corresponding compartments 35 in the movable riage 32 is adapted to move transversely of the rotary drum 38, momentarily coming to rest before each of the trays 42 'in a juxtaposed platform so that the top sheet in eachof the trays may be fed from said trays into the corresponding compartments 35 in the container 34.

It is pointed out that the container 34 is provided with a longitudinally extending plate 43, at the side of the container nearest the platforms 40. The plate 43 has its opposite ends fixed to the respective ends of the container 34, and has its lower face downwardly inclined toward the respective compartments 35. The lower face of the plate 43 is spaced from the upper edge of each of the compartments 35 to form, with said upper edge, a chute that is directed toward said compartments, said chute being adapted to receive each sheet of paper fed from a tray 42 toward a compartment 35 and direct said sheet into said compartment.

Referring now to Figures 1 and 2 in particular, it is pointed out that the double lead-screw 22 is provided with a pair of spiral grooves 44 and 45 in the manner of a con-.

ventional double lead-screw. The carriage 32 is provided with runners 46 on its lower surface slidably mounted on the tracks 30.

In addition, the carriage 32 is provided with a downwardly extending bracket 48 having a hole extending through the lower end thereof through which the double lead-screw 22 passes. The bracket 48 is provided with a follower 50 rotatably mounted in the bracket and having an elongated inner end portion that rides in the grooves in the double lead screw 22. Thus, assuming that the follower 50 is in the groove 44, when the lead screw 22 is rotated in a counter clockwise direction, as viewed in Fig. 6, rotation of said lead screw causes thebracket 48 and the carriage 32 to be fed from right to left, as viewed in Fig. 1, assuming that said carriage started from the extreme right hand position. Continuing rotation of the lead screw 22 causes the carriage 32 to be fed along the tracks 30 until the follower 50 reaches a curved reversal portion 52 at the left hand end of the groove 44, at which time continued counterclockwise rotation of the lead screw.22 causes entry of the follower 50 into the groove 45 with an ensuing reversal in movement of the carriage 32.

Extending beneath the carriage, and parallel to the double lead-screw 22, is a single thread lead-screw 54 having its opposite ends fixedly mounted in a pair of brackets 56, and having a single spiral groove 55 in its surface. The single lead screw extends through a hole provided in each of a downwardly extending pair of brackets 58 fixedly connected to the underside of the carriage 32, and through a cylindrical cam 60 located between said brackets. The cam 60 is rotatably mounted on the fixed single lead screw 54 and has a cam groove 62 in the surface thereof of the type shown in Figs. 7-9. The opposite ends of the cam 60 are bearing journaled in the brackets 58, as shown in Fig. 9. Rotation of the cam is brought about by means of the interaction of a follower 64 fixedly attached to said cam and having the end there through extending into the spiral groove 55 formed in the lead-screw 54, so that as the carriage 32 is moved relative to the tracks 30 and thus relative to the single lead-screw 54, such movement of the carriage causes rota- -tion of the cam 60 by interaction of the groove 55 and the follower 64 on the interior of said cam 60. 7

Referring to Figs. 1, 2, 7, 8 and 9, the underside of the container 34 is provided with a fixed downwardly extending stud 66. The stud 66 is movable within a slot 68 formedrin the carriage 32 and has its lowermost end located within the groove 62 in the rotary cam 60 so that rotation of the cam, which comes about as a resultof the translation of the carriage 32, causes a periodic sliding extending stud 66, sliding movement of the carriage 32,

assuming that the carriage is moving from right to left as viewed in Fig. 1, will cause clockwise rotation of the cam 60, as viewed from the right hand side of Fig. 1 when the cam groove 62 and the follower 66 are in the positions shown in Fig. 1. Continuing clockwise rotation of the cam will cause the container 34 to be moved relative to the carriage 32, said carriage continuing its movement at all times. r

When the groove 62 and follower 66 reach the relative position shown in Figs. 2 and 7 thru 9, further movement of the carriage 32 toward the left, and ensuring clockwise rotation of the cam 60, causes the follower 66 to move,

in effect, lengthwise of the cam from left to right, as viewed in Figs. 7-9, so that the container 34 remains stationary relative to the rotary drum 38, and moves toward the right relative to the carriage 32. The container 34 remains in this stationary position until the lowermost end of the cam groove 62, as viewed in Fig. 7 reaches'its uppermost position, as shown in Fig. 1, at which time further rotation of the cam 60 results in a movement of the container 34 toward the left relative to the carriage 32 and the rotary drum 38. The driving elements of the instant collator are so proportioned that the carriage 32 is adapted to slide at all times, while the container 34 is adapted to come to a temporary halt, at predetermined intervals of time, in front of successive trays 42 in each of the platforms 40, at which time, in the manner hereinafter movement of the container 34 relative to said carriage. i

described, the topmost sheet of paper in each of the trays 42 is adapted to befed into a corresponding compartment 35 in the container 34, after which the carriage 32 and container proceed to move relative to the drum 38, from for example the position shown in Fig. 1 to the position shown in Fig. 2, at which time there is another period of dwell and another set of papers is fed into the compartments 35.

The exact manner in which the sheets are sequentially fed from the trays 42 into the compartments 35 so as to arrange the papers in the proper order, will be hereinafter described in greater detail.

A second double lead-screw 70, having cam grooves 72 and 74 cut in the surface thereof, is located above the horizontal platform 28 and tracks 30 in parallel relation therewith, and has its opposite ends fixedly mounted in a pair of brackets 76. The carriage 32 is provided at its left hand end, as viewed in Fig. 1, with an outwardly extending horizontal bracket 78 having a vertical bracket 80 attached thereto and extending upwardly therefrom. The horizontal bracket 78 is also provided with a downwardly extending U-shaped clamp element 82 having its opposite ends bolted to said horizontal bracket. The U-shaped clamp 82, in conjunction with the arcuate lower edge of the upwardly extending bracket 80 serve to clamp the outer race 84 of a ball bearing '86 in fixed relation ternatively slidably mounted in the cam grooves 72 and 74 in the stationary double lead-screw 70. The double lead-screw is provided at each of its ends with an enlarged cam follower turning-groove 96. When the follower 94 reaches the left hand end of the cam groove 74, as shown in Fig. 10, there will be a camming or turning action of said follower 92 brought about by interaction of the laterally-extending portion 94 on the follower, and an apex 98 at the point of intersection of the cam grooves Hand 74. The laterally extending portion 94 is allowed to swing in a clockwise direction in the enlarged cam groove 96, and when the direction of movement of the carriage is reversed so as to move to the right, by interaction of the cam follower 50 with the rotary double lead-screw 22, the follower 94 moves from the lowermost dotted position shown in Fig. to the uppermost dotted position thus insuring movement of said cam follower into the cam groove 72 on the double lead screw 70 so that when said carriage moves toward the right, as viewed in Fig. 1, the inner race of the bearing will continue to rotate in :hfe same direction as when the carriage moves toward the The side of the inner race 88 between said bearing and the carriage is provided with a sprocket wheel 100 fixedly attached thereto and adapted to rotate therewith by virtue of the interaction of the cam follower 92 and the grooves 72 and 74 in the double lead-screw 70. The upper end of the vertical bracket 80 has a journal 102 at its upper end having a hole extending therethrough, and having a shaft 104 rotatably and laterally slidably mounted therein. The uppermost end of the vertical bracket 80 also is provided with a fixedly mounted, laterally, inwardly extending finger 106 having a downwardly extending detent 108 at its outer end, said detent being in restraining contact with a rotatable bushing 110, and riding in a peripheral groove 112 in the surface of said bushing. The bushing 110 is provided with an axially extending hole through its center; the hole is round throughout most of its circumference but is provided with a fiat or chord-like portion and the portion of the shaft 104 extending through said hole is provided with a fiat portion extending for a substantial part of its length that is located between the vertical bracket 80 and the container '34. The flat portion of the shaft 104 is in contact with the fiat portion of the hole in the rotary bushing 110 so that rotation of said bushing causes rotation of the shaft 104, while at the same time said shaft is adapted to slide laterally of said bushing 110, for purposes hereinafter described. The rotary bushing is provided at one side with a fixedly mounted sprocket Wheel 114, and a chain 116 extends around said sprocket wheel 114 and the sprocket wheel 100 on the rotary race 88 so that rotation of said race causes rotation of the rotary bushing 110 and the shaft 104. t

The rotary shaft 104 is supported adjacent its right hand end by an outwardly extending bracket 118 affixed to the container 34, the upper end of the bracket having a hole therein for said shaft through which the shaft passes. The extreme right hand end of the shaft 104 is in abutment with the left hand side of the container 34 so as to prevent right hand movement of said shaft relative to said container. Between the bracket 118 and the container 34 the shaft 104 has a small sprocket wheel 120 fixedly mounted thereon for rotation therewith the left hand side of said sprocket wheel being in abutment with the right hand face of the bracket 118 so as to prevent left hand movement of the shaft 104 relative to the bracket. Thus, by virtue of the spacial arrangement between the small sprocket wheel 120, the bracket 118 and the left hand face of the container 34, lateral movement of the shaft relative to the container is prevented, but when said container moves relative to the carriage 32 it will in turn cause lateral movement of the shaft 104 relative to the vertical bracket 80 and the large sprocket wheel 114 associated with said bracket. Accordingly, when the container 34 moves relative to the carriage 32,

in the manner described in the above paragraphs, the

shaft 104 is free to slide laterally of the vertical bracket 80, but at the same time, due to the flat portion on said shaft and on the interior of the rotary bushing 110, said shaft will continue to rotate at all times.

The upper side of the container 34 is provided with a pair of upwardly and forwardly extending arms 122 and 124 that extend towards the rotary drum 3 8, and a rotary shaft 126 is mounted in bearings provided adjacent the respective upper extremities of said arms. At the left hand end of the rotary shaft 126 there is fixedly mounted a'small sprocket wheel 128. A chain 130 connects the two small sprocket wheels 120 and 128 so that rotation of the inner bearing race 88 accordingly causes rotation of the large sprocket wheels and 114, the two smaller sprocket wheels and 128, and thus the rotary shaft 126 at the upper side of the container 34.- Rotation of the shaft 126 causes rotation of a plurality of resilient feed fingers 132 made of metal or the like and having their innermost ends fixedly connected tosaid shaft, and having their outermost ends provided with a frictional material 134 such as rubber or the like. The tips 134 of the fingers 132 are adapted to come in contact with the top most sheet in the trays 42 so that rotation of the shaft 126 causes feeding of said topmost sheet into a corresponding compartment 35 in the container 34. The fingers are of such resiliency that they will continue to feed sheets of paper from the trays regardless of the number of sheets contained therein, including the last sheet in each tray.

Referring in more detail to the arrangement of the platforms 40, it is pointed out that each of the platforms has a shaft 136 afiixed to the underside thereof and having its opposite ends extending outwardly from the platform at each end of the platform. The respective ends of each shaft 136are pivotly mounted around the periphery of a right hand disc 138, and a left hand disc 140, said discs being parallel to one another. The right and left hand discs 138 and 140 are fixedly connected to a tubular member 142 that is fixed to a rotary shaft 144 that is rotatably carried at its opposite end in a right hand bracket 146 and a left hand bracket 148, see Figs. 1 and 2 for example. At the right hand side of the drum 38 (see Figs. 2 and 6'), each of the ends of the shafts 136 that is rotatably mounted in the disc 138 is provided with a connecting am 150 having one end fixedly connected to the shaft 136, and the other end thereof pivotly connected by a pin 152 to a third disc 154, adjacent the periphery of said disc. The disc 154 is rotatably mounted about a bushing 156 afiixed to the right hand bracket 146, the center of said bushing being the axis of rotation of said third disc 154, which in a sense can be described as a cam disc. The respective points of connection 152 between the outermost end of the connecting arms 150 are equally spaced from the axis of rotation of the cam disc 154. .It is however emphasized that the axis of rotation of the cam disc is offset, downwardly and toward the right, as viewed in Fig. 6, from the axis of rotation of the shaft 144; the distance of displacement being equal to the distance between the respective axis of rotation at the opposite ends of each connecting arm. It is emphasized that the distances between the. pivotal connection of the respective connecting arms 150 to the cam disc 154, and the center of rotation of said cam disc are all equal and are located on radii of said disc, thus causing the connecting arms to be parallel to one another at all times.

By virtue of the manner in which the connecting arm 150 are connected at their respective ends to the respective platforms 40 and the cam disc 154, the axis of which is offset from the axis of rotation of the drum 38, said arms are always parallel to one another and therefore once the platforms 40 are each placed in a horizontal plane, they will remain in such a plane as they are rotated about the axis of the shaft 144.

Referring to Figs. 2, 4 and 6, there is shown a U-shaped lever 158 having rearward arms 159 and 161 pivotly connected to the right and left hand supporting brackets 146 and 148 by pivotal connections and 162 respectively at the right and left hand ends of the lever 158. Attached to the arm 159 there is a fixedly attached, downwardly extending support member 164 having a stud,.or cam follower 166 rotatably carried thereon, which stud 166 extends toward the carriage 32. On the arm 161 there is provided a rotatable, outwardly and downwardly extending stud, or cam follower 168 located in a plane higher than the right end stud 166, but like stud 166 extending toward the carriage 32. Downward movement of the U-shaped lever 158 is prevented by a stop member 170 fixed to the base of the apparatus and extending about its left hand pivot 200.

upwardly to stop the U-shaped lever in its downward movement.

Referring in detail to Fig. 4, the rearward arm 161 on the U-shaped lever 158 is provided with an upwardly extending arm 172 spaced from and substantially parallel to the rotary drum supporting bracket 148. The upwardly extending arm 172 is provided with a laterally extending finger 174 afiixed thereto and extending toward the verti cal bracket 148. The finger 174 is adapted, upon upward movement of the forward end of the U-shaped lever, to contact and turn in a counter-clockwise direction a rearwardly extending finger 176 fixedly attached to a lever 178 pivotally connected to the rotary shaft 144. The rotary lever 178 is provided at its upper end with a rotatable pawl '180 the free end of which is adapted to extend between adjacent teeth on what can be described as a ratchet wheel 182 fixedly attached to therotary shaft 144. Adjacent the opposite end of the rotary lever 178 there is afiixed one end of a coil spring 184, and the other end of the coil spring is attached to the base of the apparatus, said coil spring tending to rotate the lever about its axis in a clockwise direction, as viewed in Fig. 4. Clockwise rotation of the rotary lever 178 is arrested by a stopdetent 186 attached to the base of the machine and extending upwardly into the path of movement of an offset arm 188 provided at the lower end of the rotary lever. Free rotation of the ratchet wheel, and thus the rotary shaft 144 and the platform 40 earring means is prevented by a spring pressed ball member 190 adapted to fit between adjacent teeth of the ratchet wheel 182, the ball 190 being biased by a coil spring 192 contained within a carrier 194 connected to the supporting bracket 148.

I Thus if the forward end, or bight portion, of the U- shaped lever 158 is pivoted upwardly, the cam finger 174 .on said U-shaped lever will push downwardly n the .rearwardly extending finger 176 causing counterclockwise rotation of the rotary lever 178. Counterclockwise rota- 'tion of the lever 178 and its attached pawl 180 will be from the position shown in solid lines in Fig.- 4 to the position shown in dotted lines, with the result that the pawl moves over the top of a ratchet tooth and then drops downinto the space just behind said tooth. Then when the right hand end of the U-shaped lever is released, the action-of the coil spring 184 upon the rotary lever 178 causes clockwise rotation of said lever, thereby causing the pawl 180 to turn the ratchet wheel 182 in a clockwise direction which of course causes rotation of the rotary shaft 144, to which the ratchet wheel is attached, and also rotation of the platform supporting members 138 and 140. The elements are so proportioned that the ratchet wheel is rotated against the restraining action of the spring biased ball 190, a distance sufficient to bring the next higher platform into alignment with the upper edge of the paper receiving container 34 so that the papers in said next platform may be fed into said container.

In order to clearly understand the manner in which the bight portion of the U-shaped lever 158 is raised, reference should be had to Figs. 4, 5 and 6. The rearmost face "of the carriage 32 has attached thereto a pair of cam .plates and more specifically an upper cam plate 196 and a lower camplate 198. The upper cam plate 196, as

,viewed in Fig. 5, has its left hand end pivotly connected to the rear of the carriage 32 by a pin 200, and has a rearwardly extending, inclined cam track 202 adjacent its lower edge. The right hand end of the upper cam plate .196 is provided with an outward extension 204, the lower edge of-which is normally in abutment with a stop detent 206 adapted to prevent clockwise rotation of the cam plate 'The lowermost cam plate 198 is pivotly connected at ':its right hand end to the rear side of the carriage 32 .by a pin 206. The lower edge of the cam plate 198 ,is' provided with a rearwardly extending, inclined cam track 208 that slopes downwardly and to the left, as viewed in Fig. 5. The" lefthand 'end of the lower cam plate 198 is provided with an outward exte'nsion210,

the lower edge of which abuts a stop detent 212 adapted to prevent counterclockwise rotation of the cam plate.

The cam track 202 on the cam plate 196 is adapted to come in contact with the follower stud 168 at the left hand side of the U-shapedlever 158 as the carriage moves towards the left, as viewed in Figs. 1 and 2. As movement of the carriage 32 proceeds, the follower stud 168 is moved upwardly, as shown in dotted lines in Fig. 4, until the carriage moves a distance sufficient for said follower stud to drop free in a downward direction from the left hand edge of the cam track 202(see Fig, 5). The upward movement of the follower stud 168 causes counterclockwise rotation of the U-shaped lever 158 with an ensuing like rotation of the rotary lever 178 and backward movement of the pawl 180 so that the pawl falls into a rearward space, to the position shown in dotted lines in Fig. 4, all as set forth above. When the follower stud 168 drops free of the upper edge of the cam track 202, the U-shaped lever drops downwardly with the ensuing effect that the coil spring 184 causes clockwise rotation of the rotary lever 178 and the pawl 180 then forces the ratchet wheel 182 to turn in a clockwise direction, a distance sufficient to bring the next uppermost platform 40 into alignment with the upper edge of the sheet receiving container 34. At this point the carriage reverses its movement, through the interactions of the follower 50 and the double lead screw 22, and starts to move toward the right. Move ment continues a point where the right hand follower stud 166 on the U-shaped lever 158 contacts the cam track 208 on the lower cam plate 198, and as the carriage continues to move toward the right said follower stud is moved in an upward direction by the cam track 208 until it reaches the end of said track, at which time it drops down, causing the platform car'- rying apparatus to rotate clockwise, as viewed in Fig. 4, bringing the next uppermost platform 40 into alignment with the upper edge of the sheet receiving container 34, in much the same manner that the action of the uppermost cam track 196 causes rotation of the platform carrying drum 38 in the manner set forth above. Thus the platform carrying apparatus is caused to rotate a distance sufiicient to bring the next uppermost platform into alignment with the upper edge of the sheet receiving container as the carriage 32 reaches the respective ends of said platforms.

It is pointed out that each of the cam plates 1% and 198 is pivotly mounted adjacent one of its ends so that when the carriage is reversed, just after the respective follower studs 166 and 168 on the U-shaped lever drop off the uppermost end of the respective cam tracks, said follower studs are allowed to pass freely beneath the cam track from which it has just dropped by camming said track upwardly about the respective pivots on the cam plates.

Operation:

It is first pointed out that the trays 42 are numbered in the manner shown in Figs. 1 and 2, as for example from right to left 1, 2, 3, 4, with tray 5 being directly above tray 4, so that stacks of page 1, page 2, etc., may be placed in the respective trays so numbered. With tray 1 in the position shown, the carriage is moved to the extreme right hand position at which time the left band edge of the container 34 is approximately in alignment with the right hand'disc 138 on the drum 38,

Rotation of the double lead screw 22 is then commenced, which through the interaction of the groove 44 in the lead screw 22 and the follower 50 causes the carriage to move toward the left, as viewed in Fig. 1. As the carriage moves toward the left, the rotary cam 60 with the groove 62 in its surface, is caused to rotate in a clockwise direction, as viewed from the righthand end thereof. Rotation of the cam 60, together with movement of the carriage 32 brings the compartment marked A'into alignment with tray No, 1, at which time and by virtue of the relative proportions of the various elements, all as set forth above in detail, there is a period of dwell in movement of the container 34 relative to the platform 40 and tray No. 1, while the carriage 32 continues to move toward the left. At the same time, through interaction of the follower 92 and the groove 74 in the stationary double lead-screw 70, the sprocket wheel 100 and thus the shaft 126 are caused to rotate, said rotation being continuous and being so timed that when compartment A is juxtaposed to tray No. 1 the feed fingers 132 opposite compartment A rotate into contact with the topmost sheet of paper in the tray No. 1, thereby feeding said sheet into compartment A.

in Fig. 1, at which time further rotation of said rotary cam causes the container 34 to be moved toward the leftas the carriage likewise proceeds to move toward the left, but at a somewhat greater rate of speed until compartment A is in alignment with tray No. 2 and compartment B is in alignment with tray No. 1. At this time the rotary cam 60 has again reached the position shown in Figs. 2 and 7-9 thereby once again causing the slidable container 34 to dwell temporarily relative to the trays 1 and 2, as the carriage 32 continues to move toward the left. The dwell interval continues for a period of time long enough for the feed fingers 132 opposite compartments A and B to proceed to feed a single topmost sheet from tray No. 1 into compartment B, and a single sheet from tray No. 2 into the compartment A, thereby resulting in pages 1 and 2 being in compartment A and page 1 in compartment B. The aforementioned sequence of operations continues until the compartment D moves to the left of tray No. 4. It is pointed out that when the container 34 is being moved relative to the carriage 32, the rotary shaft 104 slides through the bearing 102 and the bushing 110 while continuously rotating, due to the flattened portion on the shaft and the interior of the bushing 1 10.

At about the time that the compartment D starts to move to the left of tray No. 4 the follower stud 168 at the left hand side of the U-shaped lever is cammed in an upward direction by the cam track 202 on the uppermost cam plate 196. As the carriage 32 continues to move toward the left, the stud 168 and therefore the U-shaped lever 158 are moved upwardly toward the dotted line position shown in Fig. 4 until said stud reaches the upper edge of the cam track 202 and drops down from said surface. By virtue of the structural relationship between the finger 174 on the upwardly extending arm 172 and the rearwardly extending finger 176 on the rotary lever 178, said rotary lever is rotated in a counterclockwise direction as the U-shaped lever rises to the dotted line position shown in Fig. 4. When the follower stud 168 drops free of the cam track 202, the spring 184 causes clockwise rotation of the rotary lever 178, thereby causing the pawl 180 to rotate the ratchet wheel 182 in a clockwise direction a number of degrees sufficient to bring the next platform 40 into alignment with the upper edge of the container 34 so that the trays 5, 6, 7 and 8 are in alignment with saidcontainer.

As the double lead screw 22 continues to rotate, the direction of movement of the carriage 32 is reversed as the follower 50 moves through the are at the left hand end of the double lead screw 22 and enters the groove 45 and the carriage feeding process continues with the compartment D temporarily stopping in front of tray No. so that a single page 5 may be fed into said compartment on top of pages l-4 already contained therein. As the carriage 32 continues to move toward the right, the sheet feeding operations are repeated during the momentary periodsof dwell on the part of the container in front of the respective trays, said dwell being brought about by virtue of the structural elements described above.

It is pointed out that as the carriage movement is reversed, the cam follower foot 94 on the arm leaves the cam groove 74, turns and enters the groove 72, so that the direction of rotation of the sprocket wheel and thus the feed fingers 132 remain the same even though the direction of carriage movement is reversed.

As the compartment A passes beyond the right hand side of the disc 138, the cam plate 198 on the rear of the carriage 32 commences to cam the follower stud 166 in an upward direction thereby causing counterclockwise rotation of the U-shaped lever 158 (see Fig. 4). This of course causes rotation of the rotary lever 178 and movement of the pawl to the dotted line position shown in Fig. 4 so that when the follower stud 166 drops over the upper edge of the cam track 208, the downward movement of the U-shaped lever 158 allows the coil spring 184 to rotate the rotary lever 178 clockwise, thereby causing the pawl 180 to rotate the ratchet wheel 182 clockwise a sufficient distance to bring the third platform into alignment with the upper edge of the container 34, at which time the carriage 32 is reversed and the aforementioned feeding steps are carried out from the trays 9, 10, 11 and 12.

The collating steps described in the paragraphs immediately above are of course repeated until the last page of a particular set has been fed into each of the compartments A thru D, at which time the apparatus may be stopped and the collated sheets removed from the compartments A thru D.

In the event that it is desired to collate more than one set of papers in each of the compartments A, B, C and D, the tray 42 following the one having the last page of a set therein is filled with colored, separation sheets adapted to be fed, one each, into the compartments A thru D after each compartment has a complete set of pages collected therein. The collating steps described above are then repeated and thus several sets of sequentially arranged pages may be collected in each compartment A-D, and subsequent separation of the sets expedited.

It is pointed out that the sheets in each of the trays 42 are prevented from sticking together by providing a beveled edge 214 at the front end of each of the trays 42, whereby the stack of sheets in each tray is feathered. In addition each of the trays may be provided with side and end adjustment members 216 to conform to the machine size, with the end adjustment member 216 being at the same angle as the beveled portion 214 at the front of the tray.

It is emphasized that the combination of the flexible spring material ejector fingers 132, the frictional members 134 thereon and the stack feathering members 214 and 216 eliminates the need for providing expensive pickup suction cups and/or various other types of such devices now used in the prior art for the purposes of preventing the feeding of more than one sheet at a time. In addition the feeding fingers 132 by their very nature have a vibrating, breaking effect on the stack of sheets in each tray thereby eliminating the problem of static electricity which may keep the sheets stuck together. The spring ejector fingers 132 also eliminate the need for a vertical adjustment means in each of the trays, since said flexible fingers adjust themselves to the thickness of the stack in said tray. Feeding of a sheet from a tray 42 is further expedited by virtue of the beveled members 214 and 216.

It should be understood that while the instant embodiment of the invention discloses only four receiver compartments A, B, C and D, and a corresponding number of trays 42 in each of the platforms 40, the invention may be constructed so as to include a greater or lesser number of receiver compartments and trays, being limited only by the practical considerations of? space and expense. For example, these could be four compartments A-D and eight trays 42 per platform 40, or alternatively eight compartments A-H and eight trays 42 per platform 40. Various other combinations within the scope of this invention will readily occur to those skilled in the art.

Thus the instant invention provides a foolproof collating apparatus that is adapted to collate a plurality of sheets of paper in such a manner that a pluralityof sets ofsuch sheets of paper may be collected substantially at one time, whereas most of the prior art devices are capable of collating only one set at a time. In addition the operation of the instant apparatus is substantially fully automatic once operation of the apparatus is com- 'It is also pointed out that an apparatus of the menced. type described above will collate 200 sets of pages, 1 thru 39, plus one colored separation sheet, at an estimated 12,000 sheets per hour based on a one way carriage traveling time of 5 seconds, the size of said sheets being 8 inches by 13 inches. It is further pointed out that the capacity of the machine will depend largely only upon the size of the various compartments utilized and the speed of rotation of the double lead screw 22.

'It should be understood, of course that the foregoing disclosure relates only to a preferred embodiment of the invention and that numerous modifications or alterations may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.
