COLLATING MACHINE 7 Sheets-Sheet 7 IN VEN TORJ' R/c/mvea 6. 40 we United States Patent 3,076,647 COLLATING MACHINE Richard G. Lowe, 19200 Westbrook, and Bertil S. Fornell, 19633 Brady, both of Detroit, Mich. Filed Nov. 18, 1960. Ser. No. 70,212 18 Claims. (Cl. 27058) This invention relates to paper printing and handling equipment and more particularly pertains to a novel collating or sorting machine which is easily integrated in co-operating relationship with printing machines to receive, sort, and accumulate printed paper sheets as they are ejected by the printing machine.

Printing machines and collating machines have been employed separately wherein all the sets of sheets are all first printed and stacked and then fed through the collating machine making two complete individual operations resulting in double handling and interim storage. For example, where to 100 booklets of 50 to 100. pages each are to be printed and compiled using prior art devices, it is necessary first to print all the sets of sheets and then keep them in identified stacks until all sheets and stacks are printed and then to-compile them-into booklets, Whereas with the instant invention, each sheet is automatically sorted and stored in bookletcompilation as fast as printed. This eliminates all interim handling 1 easily integrates with sheet printing machines in automatic operation therewith so as to-receive, sort, and .store' the sheets as fast as they are printed in a separate stack in.

separate pockets with the sheets in proper booklet se'- quence.

An object of the invention is to provide a collating machine having automatic operational timing and sheet counting in conjunction with the operation of the printing machine. I

An object of the invention is to eliminate separate stacking or-handling of the sets of printed sheets at the printing machine and to provide a collating machine toreceive each sheet from the printing machine-as it is printed.

An object of the invention is to provide a collating machine having a rotatable drum equipped with divided sheet storing compartments or pockets and which automatically indexes the compartment pockets as the sheets are printed so thatone printed sheet of each set is inserted in each pocket.

.An object of the inventionis to provide a collating machine having presettable controls for counting the desired number of sheets printed and storedof each set and then to automatically return itself-to the starting position for receiving the next set of printed sheets.

An object of the invention is to provide a collating machine for automatic operation in conjunction with a printing machine which is simple in design and construction, inexpensive to manufacture, easy to integrate with a printing machine and which is efiicient and money saving in operation.

. Referring now to the drawings wherein like designa tions refer to like and corresponding parts throughout the several views, the collator machine and-'collator-printing' machine combination disclosed therein toillustrate the invention comprises a printing machine 30 which rapidly prints and ejects sheets automatically and a collating ma-- chine 31 which automatically receives and individually stores the sheets in separate pockets of the drum 32' or in the collector tray 33 as fast as they are printed and ejected.

More particularly, the printing machine may beanyf one of many such machines and the Addressograph-Multi graph Corp. Multilith printing machine may be considered exemplary and is hereinafter referred to as a printer and comprises a sheet supply and feeding portion 34, a printing portion 35, and a sheet ejecting portion 36. The operator puts a stencil, plate, or type (not shown) to be printed on theprinter 30, places the paper 40 in position, closes the printer master switch 37, sets the printer counter 38 to the desired number of sheets to be printed, and closes the print switch 39 to the printing portion 35 whereupon the printer 30 automatically prints the desired number of sheets and upon the printer counter 38 counting out, the master switch 37 is opened and/ or the circuit to the printing portion 35 is broken by the counter 38, and the printing of sheets 40 is automatically terminated. The operator then changes the stencil, plates, or type for printing the next sheet and the printer is ready to print the next set of sheets when the operator closes the master switch, sets the printer counter, and closes the printer switch. A tray or station is usually provided on the printer 30 for receiving the printed sheets and, in the instant invention, this portion of the printer is deleted and the printed sheets ejecting from the printer are picked up by the collator as hereinafter described.

The collating or sorting machine 31, hereinafter referred to as the collator has a frame rotatably supporting the drum 32 which is rotated by the sprocket gear 41 secured to the drum 32 driven by the chain 42, reduction gears 43, brake-clutch drum-drive electric control device 44, and motor 45 which is wired in the printer master circuit in parallel so that when the printer master switch is closed, the collator master circuit is energized with the collator drum drive motor 45 running but not driving the drum 32 as the normal condition of the drumdrive control device 44 is clutch-disengaged and brake-set as hereinafter set forth.

A conveyor 46 on the collator 31 has a single receiving portion 47 for receiving the printed sheets from the printer and a dual delivery portion with top-delivery portion 48 leading to the collector tray 33 and bottom delivery portion 49 leading to the drum 32 with the dual delivery portion being separated from the single receiving portion 47 by a switch gate 50 located at the end of the conveyor receiving portion 47 with the gate being mechanically open to the collector tray 33 and normally mechanically closed to the drum 32 via spring bias.

The position of the gate 59 is reversed when the gate solenoid -1 is energized directing sheet delivery to the drum 32. The conveyor 46 is driven by the conveyor motor 52 via drive chain 53 and inter-connector chain 54 which drives the sprocket gears 54a fixed on the conveyor rollers, which in turn, drive the paper sheet engaging tapes 55 on the receiving portion and similar means, not shown, on the top delivery portion 48 to the tray and bottom delivery portion 49 to the drum; adjustable guides 56 are provided to center various sizes of paper on the conveyor. The conveyor drive motor 52 preferably is wired in parallel with the printer print switch 39 so that it runs when the printer is printing and ejecting sheets; this enables the operator to run the printer 30 without running the collator 31; and since the conveyor gate 50 is normally open to the collector tray 33, the printed sheets 40 are collected and held therein via the conveyor 46. Thus, not only does the circuit to the collator conveyor motor 52 insure its running to receive sheets from the printer 30, but it also enables use of the printer without the collator; further, it enables the operator to shut olf the conveyor 46 and the printer 39 when only the collator 3-1 is being used such as when the drum 32 pockets have the desired amount of sheets 49 and the collator drum 32 is being indexed around as hereinafter more fully described to unload the sorted and compiled sheets from the drum. With this conveyor 46 arrangement, the extra printed sheets 4% can be obtained as desired by setting the printer counter 38 higher than the collator counter; thus, when the collator counter counts out, the additional printed sheets are sent to the collector tray 33 enabling the operator to accumulate surplus or extra printed sheets 40- from the same stencil or type presently on the printer 3%.

The drum 32 as shown has fifty individual pockets 57 but may have any multiple of pockets and these may be equipped with adjustable sides 58 and a removable false bottom 59 for accommodating various size sheets of paper. The drum pockets are numbered such as 1 to 50 and when the number one pocket is at the conveyor bottom delivery portion 4?, the drum 32 is considered in the "Home position which is the starting position for setting the collator counter. The drum 32 has a home position detent 61 and pockets detents 60 at each pocket 57 which operate the home and pocket switches respectively as hereinafter more fully described.

The drum pockets 57 are radially disposed about the drum 32 rotational axis so that each pocket 57 axially aligns itself with the conveyor delivery. Gravity holds the sheets 40 in the upper portion of the drum and the arcuate strap 81 holds the paper sheets 40 in the drum 32 in the bottom portion of the drum; the rotataional direction of the drum is upwardly at the gate 50 so that the top part of each pocket is clear to receive the next sheet from the conveyor 46.

The collator counter 82 has a clutch coil C-9 operating the two position switch C10 and a count coil C-ll operating the indicator 83 which, in turn operates normally closed switch C12 to open momentarily as the counter indicator 83 reaches zero; the count coil C-ll when energized sets up the mechanism to move the counter indicator 83 down one increment upon de-energizing. The indicator is set to the desired number of sheets to be placed in sequential pockets in the drum and the indicator counts down one at a time from the number set to zero as sheets are delivered into drum pockets, and as the drum advances the next pocket.

The drum home switch H moves between the run" and the home positions and is actuated by the drum home detent 61 after the drum 32 moves 360 degrees to the home position again; when the home detent 61 is not at the home position, the home switch H is in the run position. The drum 32 is home when the number one pocket is at the sheet receiving position at the conveyor gate 50.

The drum pocket switch P moves between the closed position with the drum 32 standing with a pocket 57 in the paper receiving location and a null position in which the drum 32 rotates. When the next pocket 57 comes to the paper receiving location and switch P is closed by a detent 60 on the drum at each pocket and the drum stops in the paper receiving location. When the pocket switch P makes the circuit the counter 82 count coil 0-11 is energized and when this circuit breaks one count is counted down by the counter indicator 83 by the coil releasing the spring pressed count mechanism.

The sheet switch S is disposed between the conveyor lower delivery portion 49 and the drum pocket 57 at the receiving location and has a normally closed no sheet present position and the normally open sheet present position; when a sheet 40 is delivered by the conveyor to the drum pocket 57, the switch S is actuated by the paper 40 from the no sheet position to the sheet position; after the paper has passed into the drum pocket, the switch S returns to its normal position.

There is one latching relay CLl having a normally closed selector switch Z to the drum drive control device 44 brake coil 70 and a normally open selector switch Y to the drum drive control device 44 clutch coil 71 and these switches Y and Z are so integrated in the device that one or the other is closed actuating the drive brake coil 70 or the drive clutch coil 71 so that, at any one time, either the clutch or brake is energized and one goes off when the other goes on automatically. It is here considered normal for selector switch Z to be closed setting the brake and selector switch Y to be open disengaging the clutch in the control device 44 and these switches are operated by opposed coils CLl-L and CL1-UL.

Coil CLl-L of latch relay CLl when energized opens selector switch Z to the drum drive brake coil 70 and closes selector switch Y to the drum drive clutch coil 71 and these switches will so remain until the opposite coil CLl-UL of latch relay CLl is energized; when coil CLl-UL is energized selector switch Y to the drum drive clutch coil 71 opens and selector switch Z to the drum drive brake coil 70 closes and this condition obtains until the opposite coil CL-L is energized again as stated.

The six control relays are numerically designated CR1 through CR6 and each relay has multiple normally-open and multiple normally closed selector switches when their coils are not energized, and when the coils are energized, the selector switches change to the opposite position of open or closed as the case may be. Their actuating coils are shown on the right hand side of the wiring diagram and their selector switches are disposed throughout the diagram to simplify the wiring. The selector switches are alphabetically designated A through X with a prefix designating the operating relay and the relay coils are considered normally not energized.

A normally open start switch 62 and a normally closed re-set switch 63 are in series with the counter 82 clutch coil C-9 so that when the start switch 62 is closed counter coil C-9 is energized moving counter switch C- oil pole (3-8 and on pole C-7 closing a shunt circuit around the start switch 62 through normally closed reset switch 63 and through normally closed counter switch C-13 locking in the counter clutch coil C-9. Upon the counter 82 counting out to zero, switch C13 is momentarily operated by the counter indicator 83 breaking the shunt circuit deenergizing counter clutch coil C9 permitting counter switch C-10 to move oil counter pole 7 and contact counter pole 8. Counter pole 8 is in series with the collator home switch H circuit and also in series with the drum unloading switch 64 whereas counter pole 7 is in series circuit with the drum pocket switch P, the sheet switch S, and the manually operated normally closed reject switch 65 to the gate solenoid coil 66 which is energized when the start switch 62 is closed to swing the conveyor gate 50 to the bottom delivery portion 49 to the drum 32; pressing the reject switch button opens the reject switch 65 breaking the circuit to the gate solenoid-coil 66 allowing the gate 50 to move via spring bias to its normal position directing sheets to the conveyor upper delivery portion 48 to the collector tray.

In loading the collator drum automatically with printed sheets only control relays CR1 and CR2 are used, whereas, in unloading the drum control relays CR3 through CR6 are also used.

The drum drive control device 44 brake coil 70 and the drum drive control device 44 clutch coil 71 are shown in a direct current circuit as developed by the full wave rectifier 72 but the drum drive circuit may be operated by alternating current or otherwise, if desired. t

After previous collator use and unloading, the collator drum 32 is usually not in the proper position to start receiving sheets 40 from the printer 30 and the collator circuit is integrated so that upon closing the master switch 80,- with the counter 82 at zero, the drum 32 will automatically be rotated to the home position as counter 82 switch C-10 feeds current to counter pole C-S to the home switch S in the run position which energizes latch relay coil CLl-L opening selector switch Z to the drum drive brake coil 70 and closing selector switch Y to the drum drive clutch coil 71 and this condition obtains until the drum home detent 61 moves the home switch H from the run position to the home position de-energizing latchrelay coil CLl-L opening selector switch Y to the drum drive clutch coil 71 and energ zing latch relay coil CLl-UL closing selector switch Z to the drum drive brake coil 70. This automatically conditions the collator for operation with the printer with the collator counter at zero and the vdrum 32 at the home position.

It is important to remember that this hook-up is not only effective after previous use and after unloading but it is also eifective every time the collator counter 82 counts to zero as movement of the counter indicator 83 to zero momentarily opens counter switch C-12 breaking the shunt circuit to thecounter clutch coil C-9 permitting c'ounter switch C-10 to move to normal contact with counter pole C-S leading to the home switch H common side. This transfers power from thepocket switch P and sheet switch S deactivating their circuits and as the home switch H is in the Run position, it keeps the drum turning through latch relay coil CLl-L to selector switch Y to the drum drive clutch 71 and upon the drum arriving at the home position the home detent 61 thereon moves the home switch H from the Run to the Home position cutting power from the drum drive clutch 71 and throwing power to the drum drive brake.70 via selector switch Z and latch relay coil CL1UL.. This stops the drum at home automatically every. time the collator counter counts out so that the drum is automaticallyproperly positioned each time. The utility of this operation can be better understood by the realization that the collator is usually used at less than its full capacity of pockets requiring that the last unused pockets be skipped.

For example, in a fifty-pocket drum, sheet assemblies of less than fifty are more usually compiled than the full capacity. This suits the device to the actual needs of the job, insures accurate sheet compilation, and eliminates manual run-out of unused pockets. It is also important to note that upon closing the master switch the drum automatically homes prior to pressing the start button as the drum homing circuit is energized with the counter switch C-10 normally contacting counter pole C-8 leading to the home switch H.

Readying for Operation As previously indicated, the printer 30 is set for operation when the proper stencil or type is installed, a supply of paper 40 in station 34, the printer counter 38 set to the desired number of sheets to be printed such as 60, and the printer master switch 37 closed powering the printer and the collator conveyor 46; the printer 30 is now ready to print and the collator conveyor ready to deliver upon the printer print" switch 39 being closed.

Preferably the collator master circuit is wired in parallel with the printer master switch 37 thereby eliminating the necessity for a collator master switch which has been shown and described for purposes of illustration.

- Thus with the collator master circuit wired in parallel with the printer master circuit, immediately upon closing the printer master switch 37, both machines are ready to operate as the drum imediately homes, the collator conveyor motor 52 is running, and the collator drum drive motor 45 is running as is the printer drive motor, not shown.

With the drum at home and the machine powered, the operator sets the collator counter 82 to the number of sheets to be collated into drum 32 pockets 57, such as 40 sheets, and presses the start switch 62 button with the drum at home which causes the collator counter 82 to lock itself in dis-connecting the home switch H and connecting in the pocket switch P and the sheet switch S. This sets the collator 31 for action with theprinter 30 with collator counter coil C-11 energized throughpocket switch P, with control relay CR2 energized through sheet switch S directlyand also through selector switches CLl-UL-R and CR2-Q and with selector switch Z closed energizing drum drive brake coil 70. Both machines are now ready for operation with the pocket switch P on a pocket detent 6i) and sheet switch S at the no sheet" contact.

The operator now presses the pint switch 3-9 button on the printer 30.

. Operation Immediately upon the operator pressing the print button, the printer Btlprints a sheet 40, ejects it to the collator conveyor 46, and the collator conveyor delivers the sheet through the gate 50 into the drum pocket57 past the sheet switch S moving switch S from the no sheet position which breaks the direct circuit to CR2 coil (coil CR2 then holds on shunt circuit through sei lector switches CLl-UL-R and CR2-Q) and moves switch S to the sheet position connecting in the coil of CR1 through selector switch CR2-N, and also connecting in the coil of CLl-L through. selector switches CR2-N, CR1-F, and the hold switch 73 whereupon CLl-L being energized selector switch Z opens to the drum drive brake coil 70 and selector switch Y closes to the drum drive clutch coil 71 and the drum 32 starts to rotate.

Immediately upon the drum rotating the pocket switch P falls oil the pocket detent 60 and opens all'circuits from the pocket switch P which de-energizes collator counter coil C-ll allowing spring release which moves the counter indicator 83 one increment and which deenergizes CR1 coil opening selector switches CR1-F and CR1-M and closing selector switches CR1-L and CR1-P.

The sheet 49 enters the drum as the drum starts to move and the sheet switch S after the sheet passes moves backs to its no sheet position again energizing the coil of CR2. The drum continues to move with the sheet .in the pocket until the next pocket detent contacts the pocket switch P.

Imediately upon the pocket switch P riding up the next pocket detent 69, the pocket switch P closes energizing the coil of CLl-UL through selector switches CRl-L, CRZ-H, and CRS-K whereupon selector switch Y opens to the drum drive clutch coil 71 and selector switch Z closes to the drum drive brake coil 71 stopping the drum 32. Concurrently, as soon as coil CLl-L is energized selector switch CLl-UL-R opens breaking the shunt circuit to CR2.

Now we see in the basic operation circuits that, when the pocket switch P is off pocket detent 60 it is completely inactive and that when it contacts a pocket detent 6% on the drum that it basically and normally stops the rotation of the drum with the next pocket at the conveyor delivery station.

Also we see that in the basic operation circuits that when the sheet switch S is actuated by a sheet passing it, that it basically and normally starts the drum rotating from the last pocket position.

Thus every time a sheet is delivered by the printer via the conveyor to a pocket the sheet switch S is activated by a delivery and causes the drum to rotate, and, upon the drum moving one pocket rotation the pocket switch P hits the next detent and stops the drum with the next pocket in position for delivery of the next printed sheet from the printer.

Every time the printer prints a sheet and the conveyor delivers it to the drum, the sheet switch S changes position momentarily while the sheet passes and this change in position starts the drum rotating and every time the drum moves, the collator counter counts one increment when the pocket switch P opens when it falls off the last pocket detent and when the pocket switch P contacts the next pocket detent it closes stopping the drum and again energizing the counter count coil -11.

After 40 sheets have been delivered to the drum in 40 sequential pockets, the collator counter 32 counts out and as the collator counter indicator 83 moves to zero it momentarily opens counter switch C-12 de-energizing counter clutch coil C-9 letting counter switch C-IO break with pole C-7 and make with pole C-8. Upon breaking the circuit to pole C7, the circuit to the pocket switch P, sheet switch S, and conveyor gate solenoid coil 66 are all broken so that the gate 50 in the conveyor closes to the drum and directs the next printed sheet 40 from the printer 30 to the collector tray 33 and upon the printer counter 38 counting out, the print switch 39 is opened and further printing stops. Upon collator counter 82 switch C-10 making with pole 8, the home switch H is energized in the Run position sending current to CLl-L which opens selector switch Z to the drum drive brake coil 70 and closes selector switch Y to the drum drive clutch coil 71 which drives the drum to the home position where the home detent moves switch H to the home position cutting power to CLl-L and connecting power to CLl-UL which opens selector switch Y to the drum drive clutch coil 71 and closes switch Z to the drum 'drive brake coil 70 stopping the drum in the home position.

The operator now quickly changes the stencil on the printer, sets the counters on the printer and the collator, and pushes the print button on the printer. The operation previously described again occurs. Assuming that a 75 sheet booklet is being run off, the operator will change the stencil, set the counters, and push the print button 75 times whereupon he will have 75 difierent sheets in each of 40 drum pockets as he has had the collator counter set at 40 each time. He will also have all the overrun extra sheets in the collector tray for each particular time he has set the printer counter higher than the collator counter. If the operator sets the printer counter at 60 every time, he will have 20 extra printed copies of each sheet printed in the collector tray. Conversely, if he sets both the printer counter and the collator counter at the same number, there will be no extra sheets in the tray.

The operator removes the collector tray 33 from the collator 31 and removes the collected sheets 4-9 from the drum 32 manually by pressing the unload switch 64 to bring the loaded drum pockets to the top of the machine so that the sheets 41 can be lifted out of the pockets 57.

Unloading the Drum Bearing in mind that we have power to the common side of the home switch H as well as the unload switch 64 with the collator counter 82 at zero, we now proceed to unload the drum 32 by operating the double-pole double-throw unload switch 64. This send current to the coil of CR-3 through selector switch CR6-X. With the coil of CR-3 energized selector switches CR3A and CR3-S are closed and selector switches CR3-B and CRS-K are opened. With the opening of selector switch CR3-K power is removed from latching relay coil CL1(UL) and with the closing of selector switch CR3-A power is applied to latching relay coil CL1(L). This power transfer closes selector switch Y and opens Z causing the drum 32 to move.

With sutticient movement of the drum 32 to cause the home switch H to roll off the home detent 61, the home switch H closes in the Run position energizing CR-4 coil through the now closed selector switch CR3-S.

When the coil of CR-4 is energized selector switches CR4D, and T, and CR4-W are closed and selector switch CPA-G is opened. With the closeure of selector switches CR4T and CPA-W the coil of CR-S is energized closing selector switch CR5-V and scaling in both CR4 and CR-S coils through selector switches CR4-T, CR6-U, CR5-V, and CR4-W.

At any point during the unload cycle the movement of the drum 32 may be stopped by releasing the Unload switch 64 push button which opens the circuit and allows the coil of CR-3 to fall out opening selector switches CRS-A and CRS-S and closing selector switch CR3-K. With this, power is released from CLl-(L) coil and applied to CLl-(UL) coil through selector switch CR3-K and the now sealed in selector switch CRS-E stopping the drum 32.

Pressing the Unload button again, reverses the action as described in the preceding paragraph and the drum 32 revolves until the home switch H rides up on the home detent. When this happens current flows through the sealed selector switch CR4-D and energizes the coil of CR6. When CR-6 is energized selector switches CR6-U and CR6-X are opened which allows the coil of CR-3 to drop out. Relay coils CR-4 and CR-S would also fall out except that they are held in through the second set of circuits including selector switches CR4T and CR4-W. With the selector switches in this position selector switch CR3A also opens when the coil of CR-3 drops out removing power from CLl-(L) coil and power is applied from the common side on the home switch H through selector switches CRS-E and CR3-K to the coil of CLl-(UL) releasing the drum drive clutch and applying the brake to the drum drive stopping the drum.

Releasing the unload switch 64 push button allows the coils of CR-4, CR-S, and CR-6 to drop out and prepares the circuit for another unload cycle or pressure on the Start button. Obviously the operator removes the sets of collated sheets from the drum pockets as they come over the top position and the usual operation is to press the unload button until several pockets are on 9 top; then release the button and remove the sheets from the drum. This operation is repeated until the drum is completely unloaded.

Special Circumstance Controls Any time the manually operated reset switch 63 push button is momentarily pressed both the direct and shunt circuits to the counter 82 clutch coil 0-9 are broken deenergizing counter clutch coil 0-9 which permits counter switch C-lt) to disengage counter pole C-7 to the collator operation circuits, and to engage counter pole 0-8 to the home switch H whereupon the drum 32 normally is rotated to the home position. Thus the reset switch permits complete interruption and resetting,

' Pressing the hold switch 73 push button opens the hold switch 73 and interrupts current to latch relay coil CLl-(L) and will continue to do so as long as held. When hold switch 73 is'released the drum moves to the next pocket and stops.

In the event the sheet switch S is held in the sheet present position by a paper jam, selector switch CR2-O will close with the opening of selector switch CLl-UL-R and selector switch CRl-P will close when the pocket switch P rolls oif the pocket detent 60 and the coil of CR2 is cut out as both circuits to CR2 coil are interrupted. With CR2 coil de-energized selector switches CRZ-H, CRZ-N, and CR2-Q are open and CRZ-O is closed and since selector switch CR2-H is open latch relay CLl-UL coil is interrupted from power through selector switch CRZ-H. However, with selector switches CRZ-O and CR1-P closed there is acomplete circuit to the coil of CR6 closing selector switch CR6-J and allowing pocket switch P to energize the coil of CLl-UL when the pocket switch P reaches the next drum pocket detent 60 through selector switches CRS-I, CR6-I, CR3-K, and CR1-L causing the drum 32 to stop. The drum will remain stopped until the paper jam is removed from under the sheet switch S.

Manual pressure on the reject switch 65 push button opens reject switch 65 de-energizing the conveyor 46 gate 50 solenoid 66 which 'permits the gate 50 under spring bias to move to its normal position of directing sheets from the conveyor receiving portion 47 to the upper conveyor delivery portion 48 leading to the collector tray 33; this closes off delivery of sheets to the drum 32.

Referring to FIGS. 1, 2, and 3, the paper accumulator bin assembly 90 comprises a bracket 91 having an inverted U shaped hook portion 92 detachably gripping the collator panel 93 at one end and a bin supporting trough 94 at the other end; the bin 95 sits in the trough 94 and is easily set thereon and removed therefrom by the operator. The bin 95 comprises two

sides

96 and, 97 set at right angles and an interconnecting bottom 98 and since the bin 95 sits at an angle with the

sides

96 and 97 slanting downwardly to the bottom 98, and, since the bottom 98 is also at an angle, the cross laid

papers

99 and 100 are confined by the sides and bottom via gravity.

The bin assembly 90 is highly useful in conjunction with unloading the drum as sets of papers 99 arelaid one way and sets of papers 100 are laid the other way with their edges accurately aligned by the bin sides 96 and 97 supported by the bottom 98. After a bin '95 is filled it is easily removed and replaced by a similar bin 95 and thus the operator can quickly remove sheets from the drum pockets and alternate their ends against the bin sides so that each set of sheets is readily identifiable for subsequent removal from the bin.

' .The collector tray 33, FIG. 11, has paired extending arms 110 abutting the collator cross rod 111 and forked ends 112 engaging the collator rod 113 demountably mounting the tray 33 on the collator for easy insertion and removal as the operator has only to lift the tray 33 endwise outwardly from the position seen to. etfect re- 10' moval and to reverse the movement to efiect insertion; The tray 33 bottom end 114 between the arms inwardly inclines for camming the sheets delivered thereto toward the bottom of the tray and has a flange 116 for underlying the conveyor portion 48.

With'the conveyor gate 50 in the dotted line position a sheet of paper speedily travels along the conveyor 46 to the gate 50 and then upwardly over conveyor 48 from where it is projected upwardly past the tray 33 lip flange 116 whereupon it falls into the tray and settles against the bottom end 114. If the tray 33 fills with sheets, it is easily removed and supplanted with a like tray; or if desired, different sheets can be kept in different trays thereby providing temporary protective containers.

It can now be seen with the novel collator-printer combination that one operator is provided with equipment for single-handedly printing and sorting multiple multi-page booklets or brochures with the machines printing,- sorting, storing, and collating automatically as fast as each sheet is printed and also that extra sheets can be printed if desired. One operator can easily supply the paper,- change the stencils, set the counters, and push the switch buttons as this is all the operator has to do; the machine then automatically prints, collates, and stores extra sheets and while this is going on the operator readies the next stencil for quick change. Thus one operator can completely do a job in a short time which previously took many people a much longer time, I Moreover only a small space is required for thecomplete. job whereas formerly a large area was required. t t
