37 Claims.' (Cl. 270-52) 'I'his invention relates in general to sheet assembling machines and in particular to a device adapted to afx carbon paper from a roll to individual flat sheets and then to affix any desired number of flat sheets together to form a set.

In the commercial world, as well as in other fields, occasions necessitate the use of multiple copies of invoices, shipping blanks, orders, message forms and the like, wherein the copies may be of various colors, forms or bear consecutive numbers or other indicia to form a set, with a sheet of carbon paper between copies.

As far as we are aware sets of this nature have heretofore been assembled either by hand or by a device which feeds the printed forms and the carbon paper from rolls arranged vertically and obviously limited to the number of copies which may be assembled, since means must be provided for handling a separate roll for each sheet in the set, and for handling a separate roll of carbon paper for feeding between sheets of the set. In such a setup a roll of printed paper and a roll of carbon paper must be provided for every sheet in a set. v

In our device, where individual hat sheets are employed, only one roll of carbon paper is needed since this roll provides a sheet of carbon paper foreach individual flat sheet andsets may be formed with any desired number of flat sheets and interleaved carbon paper.

The objects of our invention are: first; to provide in a sheet assembling machine, flat-sheet feeding means, means for feeding carbon paper from a roll, means for securingthe at sheets and carbon paper together, and means for securing a plurality of flat -sheets and carbons together to form a set.

Second; to provide in a sheet assembling machine employing-flat sheets and a roll of carbon paper, means for applying adhesive to a .portion of each flat sheet, means for applying a sheet of carbon paper to a portion of the adhesive on each sheet, and means for combining a plurality of fiat sheets and carbons and forcing the adhesive bearing portions together to forma set.

Third; to provide in a sheet assembling machine, manual means for preventing adhesive application and carbon paper feeding during the feeding of the initial flat sheet for each set, and synchronous means in connection with the manual means for timing the kmoment of commencement and termination of carbon paper feeding.

Fourth; tofprovide in a sheet assembling machine of the class described, automatic` means operable byj the flat .sheet'being fed, to actuate the'carbon paper feeding means,rwhereby a predetermined amount of carbon paper will' be fed into applying'position only whenV a flat sheet is being fed.`

Fifthyto provide in' a sheet assembling machine, means for bringing flat sheets and sheets of Vcarbon paper into alignment, securing them Atogether and transferring them to a binding `means where any desired number of flat sheets and carbons are aligned and secured together to form a set.

Sixth; to provide in a sheet assembling machine, a pivoted carbon paper receiving table,

knives associated with the table, and means for rocking the table tov sever the carbonv paper and bring the severed pieceof carbon paper into engagement with a flat sheet for aflixing thereto.

Seventh; to provide in'a sheet assembling machine, a sheet receiving table arranged for vertical movement, means normally urging the table upward, and releasable stop means normally preventing upward movement of the table..

Eighth; to provide in a sheet assembling machine, a binding means in connection With a receiving table, said binding means 'being adapted to be forced down against the sheets at the moment of sheet deposit tovsecure the Vsheets together.

Ninth; to provide in a nat-sheet assembling machine, sheet feeding means and sheety introducing means adapted to supply a sheet to the feeding means at a predetermined moment.

Tenth; to provide in a flat-sheet assembling machine, a reciprocating transfer means for picking up, carrying and depositing sheets and ,carbon papers to a receiving means, suction means carried by the transfer means, and means adapted to release the suction at themoment of sheet deposit. y

Referring now to the drawings by numerals of reference, I designates a table frame with legs orstandards 2 and intermediate braces 3 and 4.

Sheet introducing means are provided by pivoted table hinged at 6 and having one end 1 normally lower than the level of table I to provide shoulder 8 forming a guide against which theV fiat sheets may abut during introduction to the feeding means. Longitudinal guide 9V may also be provided on the introducing table.

Sheet feeding means include pulleys I0. on suitably journaled shafts II andV II and belts I2 running on flat top surface of table frame I and extending partly over the introducing table 5.

Sheet perforating means include a notched disc I3 vertically. adjustable in. bracket I4 which in turn is horizontally slidable cnY support I5 of table. I. An opening I6 is provided in the table anda driven disc I1.- projects therethrough and engages the notched disc I3.

Adhesive applying means include a wheel I 8. rotatable with shaft I9 and extending through opening 29 in table top. The wheel may be providedwith several groovesv 2-I. A finger 22 carriedby support I5. has one end thereof inalignment with one of the grooves and is adapted to ride the flat sheets and urge them against the wheel.

The adhesive applying wheel IS-rotates in a removable-container`23 holding an adhesive uid. Further detailed particulars regarding the adhesive applyingmeans will be given hereinafter.

The sheet feeding means moves the flatsheets to the end I of the table where guides or alignersare provided to. properly position each sheet. 'Ihelongitudinal guide 24. is adjustably carried onlrods 25,.slidably supported in-brackets 26, and transverse guide 21 is.slidably carried on rod 28 fixed to cross bar 29.

ForY accurate alignment of the sheets, means for jogging orimparting anY intermittent movement .to the guides is provided-on the longitudinal guide-by diagonally slotted ends 39 on rods 25, arms V,3l havingpins working in said slots, the arms being secured to shaft 32 suitablyY carried by the table, and supporting one endY of ythe-cross bar 29. Spring 33 normally urges the shaft 32 in one direction, and other means, hereinafter disclosed, arefprovided for urging, the shaft in the opposite` direction to actuate. the arms 3l and cross bar 29 to.jog the sheet at the `guides for proper alignment. The other end of the.cross bar 29 is resiliently mounted in thetable I at 34.

Suitable sheet holddowns 35 may be adjustably carried on rods which in turn are transversely adjustable on rods 31 carried in brackets 26.`

In the carbon paper feeding means a roll of carbon paper 33 is carried on suitably journaled shaft 39,7a spring 39 keeping the roll at proper tension a'ndfin proper feedingzposition. The carbon paper passes along guide 40 and between feed rollers 4I and 42. An arcuate guide 43 directs the carbon paper around the roller 4I and onto guide 4,4 from whence it` passes between knives 45l and 46 onto a carbon paper receiving table 41. The knife 45 may be carried by the table frame I and the knife 46 by the table 41. The carbon paper receiving table 41 is suitably pivoted at 48 and is adapted to be intermittently rocked by mechanism hereinafter disclosed.

To maintain proper cutting relation between the knives, an adjustable friction plate 41', carried by the table frame I, is adapted to bear against the end of the table 41 opposite the knives.

After the carbon` paper is severed and secured to the flat sheets, the combined sheet and carbon is transferred to. a vertically movable receiving table. 49. carried on standard 50 sleeved in cylinder 5I of cross frame 52 and normally urged upward by spring 53. (See Figs. 3 and 4.)

To hold receiving table 49 locked against upward movement as it moves downwardly we have provided a lever or dog 54, operatingv in slot 55 of cylinder 5I and having offset pivot 56. The leverv 54 is normally urged against the standard 50 by spring 51..

For assisting in the alignment of the sheets on theY receiving table 49, adjustable guides 58 and 59 may-be provided, said guides being positioned in slotted openings 60 and 6I of the receiving table,` the binding means forminga guide for one edge of the sheets.

To transfer the fiat sheets and carbon paper to the receivingy table 49 we have provided a reciprocating carriage 62 having a sheet pickup or suction bar 63 with suction openings 64 in the bottom thereof. (See Fig. 10.) To the carriage are secured rods 65 vertically slidable in heads 66 horizontally movable onrods 61 carried by the table frame I. The lower end of each rod 65 is secured to plates68 and the plates andcarriage are normally urgedfupwardA by springs 69. The reciprocating mechanism for the carriagewill be described hereinafter. The carriage is depressed into sheet pickup position by the cams v contacting the lroller 1I. on plates 68 and forcing said plates and attached rods 65 downwardly.

As shown in Fig. 10, a swinging sheet guide 12 is provided and is adapted to bey moved out ofthe path ofthe suction bar 63 by means hereinafter related. A suction bar holddown member- 63 is also providedon thetable frame for contacting the, suction bar during sheet pickup. The suction bar 63gcarries a` suction relief Valve 13 adapted to be operated during. sheet deposit by. slidable member 14..striking xed stop 15.'

Immediately upon alignment and during deposit ofthe transferred sheets, binding means are adapted tocome into play. This binding means comprises. a frame 16v carried by rods 11 arranged for vertical movement in bearings 18 and normally urged upwardlyby springs 19.. This frame has a plurality of` vertical fingers V8E) abutting oneedgeofithe receiving table 49, the fingersghaving, angular ends 8|. adapted to bear against the. sheets and lcarbon paper onthe table 4 9,wh en the frame 16,is depressed.

The. binding` frame 16V is .provided with offset hook portionsSZ (see. Figs. 3 and4) in which plates.68.of carriage 62 are adapted to enter during` sheet deposit, saidplates. and theV attached carriage being adapted to be moved downwardly. Guide ears 62 on the carriage 62 are adapted to engage and movevertically in guides 62 on the table frame to positively guide thel carriage-62 dur-ing vertical deposit movement. 7

It will be noted that -the strain is taken by the binding means, the transfer carriage merel'yfbeing-carried downwardly with the frame 16 and not exerting `any force against the sheets onl the receiving ta'ble 49.v Operating means for the .binding means will be described hereinafter.

A hopper or sheet striker is provided by flexible ngers 83 carried on shaft 84, rotatable by pinion 85 and rackr 86, the operating means for said rack being disclosed later. vThe fingers 83 are adaptedto berapidly'swung arcuately -between the binding fingers 80 to strike Ythe assembled sheets after the reciprocating'carriage has deposited each sheet and' has left deposit position or at least has moved cleared of the path of the flopper fingers 8,3. A flopper strike bar 81 of suitable sound deadening material may be secured to the table frame I.

The driving source for all the moving mechanisin may be an electric motor 88 or any other suitable power unit, geared down through reduction unit 89 driving shaft 90 suitably journaled in the table frame I. A switch 88 for controlling the current source to the moto-r is shown but any suitable switching means Ymay be used, such as a foot control or the like.

The sheet introducing table 5 isactuated by cam 9| on shaft 90, said cam contacting roller 92 on upright connecting rod 93 pivotally secured tothe table 5. (Fig. 9.)

The sheet feeding pulleys and belts I and I2 are driven by bevel gear 94 on shaft 90, driving gear 95, sprocket 96, chain 91, and sprocket 98 on shaft II.

The sheet perforating .means are driven by bevel gear 99 meshing with gear |00 on shaft II and Ygear, |0| meshingwith gear |02 on shaft |03 onwhich the perforating disc is mounted.

In theadhesive applying means it is necessary that the wheel I8 and container 23 be removable andit is also necessary that means be provided to render the adhesive applying means inoperative by moving the same out of the path of the sheets.A It is to be understood that this is done ordinarily only during the feeding of the first sheet for thestart of each set, which sheet obviously does not require any carbon paper and therefore no adhesive.

Toward this end We have provided on the hub of thewheel I8, a pin |04 adapted to engage groove in shaft I9 and to enter leg |06 of said groove. The container 23 is provided with a collar |01 having slot |08, thecollar |01 being adapted to sleeve over collar |09 of bracket IIO, the shaft I9 bearing in said collar |09 and the slot' |08 in collar |01 being adapted to engage the bracket 0. The bracket |I0 is provided with a vsecond collar III which is sleeved on shaft |03 of the perforating disc I1. Shaft |9 is driven by pulleys. I|2 and belt ,I I3.

To retain the adhesive applying assembly in raised position we have provided a yoke I I4 carried by offset arm |I5 of rod IIB, and bearing against the collar |01.

The rod ||6 is suitably supported for vertical movement, is normally urged upward by springs II1, and terminates at its base with a suitable foot pedal II8. As shown in Figs. 1, 6 and 9, it will be notedA that the offset arm'may be Aswung clear of 4the bracket IIO to facilitate removal of the adhesive container and wheel.

The sheet joggers are motivated by cam ||9 on disc IIS' carried by shaft 9|)l said cam actuating `a. rocker arm |20 on shaft |20 suitably journaled tothe table frame and extending upwardly to terminate in an arm |2| adapted to bear against depending leg |22 `of 'cross bar 29. Movementof the cross bar will cause longitudinalinovement of thefshaft 32, causing pins on armsy 3| to slide in slotted ends 30 of rods 25, forcing said rods inwardly, providing for an intermittent jogging of the guides 24 and 21.

In the carbon paper feeding mechanism the perforating disc shaft |03 extends transversely of the table frame I and carries pulley |23 driving pulley |24 through belt |25. The pulley |24 freely rotates on shaft |26 of feed roller 4I, said shaft carrying gear 4I on the opposite side of the table in mesh with gear 42' on shaft 42 of roller 42.

The pulley |24 carries a clutch cone |21 adapted to engage tapered recess in drum |28 which is secured to the shaft |26. A yoke bracket |29 carries clutch actuating lever |30, the other end of which is operatively engaged with solenoid |3I. v-A brake shoe |32 is operatively related to the drum |28 and is carried on rod |33 slidably mounted'in bracket |34, the shoe |32 being normally urged against Vthe drum by spring |35, a pivoted lever |36 being adapted to slidably actuate the'rod |33, the end |31 of said leverbeing I operatively connected to a solenoid |38.

In connection with the solenoids and the related mechanism which they actuate, attention is invited to the circuit diagram in Fig. 8 as well as to the other views showing carbon paper feed control mechanism.

One of the novel features of our machine lies inthe use of the ilat sheet being fed to automatically start and stop the carbon paper feeding means.

Although other means may be employed with equal results we have preferred to illustrate an electric eye or photoelectric cell as a means for controlling the starting and stopping of the carbon .paper feed.

As shown in the various views and particularly in Fig. 5, a photoelectric cell |39 is mounted above the table I and the rays from an incandescent bulb |40 are adapted to pass through opening |4I in the table, the cell |39 being focused to catch the rays.

As far as, the photoelectric cell is concerned, the circuit usedto convey the energy from said cell is standard land well known, a relay |42 and switch control |43 being connected in the circuit and energized by action of the photoelectric cell.

One conductor |44 of the current source line is connected to one side of the switch I43, the other conductor |45 being connected to each of the solenoids A |3| land |38. Another conductor |46 connects the two solenoids and the switch |43.

Under normal conditions when there is no sheet in the feeding means the opening |4| is unobstructed and the rays from the incandescent bulb pass therethrough and actuate the photoelectric cell which, in turn, actuates th-e relay and switch to maintain an open circuit, whereby the solenoids will be inoperative and the clutch will remain disengaged andthe brake engaged to prevent carbon paper feeding.

Howeverthe moment the light ray is broken or obstructed so that it cannot reach the photoelectric cell, the relayand switch will operate to closethe circuit and operatethe solenoids for immediate engagement-of the clutchand release of the brake.

The purpose for providing a brake is to insure immediate stopping of the carbon feed rollers upon passage of a sheet beyond the,l light rayV and upon release of the clutch.

As heretofore explained, when feeding the initial sheet for each set, it is not desired to apply an adhesive thereto orto supply carbon paper therefor. However, while the initial sheet is approaching the adhesive applying means, the preceding sheet is passing through the carbon paper feeding stage, and it is necessary to continue the carbon paper feeding operation for said preceding sheet. In other words, it is desired to operate a manual control for moving the adhesive applying means out of the path of the initial sheet without rendering the carbon paper feeding means inoperative while the preceding sheet is passing through the carbon paper feeding stage. But it is necessary to render and hold inoperative the carbon paper feeding means while the initial sheet is passing through the carbon paper feeding stage.

Toward this end we have provided the mechanism heretofore described for raising and lowering the adhesive applying means, and in connection therewith we have provided, as a preferred method for accomplishing our purpose, a mercury switch |41 mounted for tiltable movement and incorporated in the circuit to the solenoids. A lever |48 is adapted to tilt the Switch |41 and is secured to a resilient lever |49 having a detent |50 engageable in slot |5| of drum |52 on shaft 90. The resilient lever |49 is carried by arm |53 on rod ||6.

In operation, when the foot pedal H8 is depressed the adhesive applying means will irnmediately be removed from the path of the sheet being fed. However, the carbon paper feeding mechanism will continue to be operative bythe preceding sheet passing below the photoelectric cell, until the detent |50 riding the outer periphery of drum |52, upon depressing of the pedal, enters the slot permitting downward movement of lever |48 and subsequent tilting of the mercury switch |41 for opening of the circuit in which the clutch and brake operating solenoids are connected. The slot |5| and drum |52 are so arranged and timed as to prevent entrance of the detent |50 until the preceding sheet has passed through the carbon paper feeding stage. Conversely, upon release of the foot pedal for return of adhesive applying means to Operating position for the sheet following the initial sheet, the carbon paper feeding means will be retained in inoperative position during passage of the initial sheet through said carbon paper feeding stage, the detent |50 being urged against the inner periphery of the drum |52 until in alignment with and released through the slot |5|, said release occurring after the initial sheet has passed through the carbon paper feeding stage and before the following sheet has reached the carbon paper feeding stage. Release of the detent |50 will cause the mercury switch |741 to close the circuit between the solenoids and the switch |43, permitting normal opening and closing of the circuit by operation of the photoelectric cell.

The pivoted carbon paper receiving table 41. is rocked or actuated by lever |54 and link |55 pivotally secured to table 41, the lever |54 being carried on shaft |56 having rocker arm |51 and roller |58 contacting and rockable byk cam wheel |59 on shaft |60l rotatable by sprocket |6|, and chain |62 on sprocket |63 of shaft 90. yA spring |64 normally urges rocker arm |5| downwardly to retain roller |58 against the cam wheel |59.

The transfer carriage 62 is adapted to be reciprocated by lever extension |65 on disc H9', said extension pivotally carrying lever |66 having a slotted end |61 slidably connected to lever |68. Said lever |68 is carried on a shaft |68 and sleeve arms |69 are carried at both ends of shaft |68. Rods are slidably positioned in the arms |69 and have forked ends in pivotal connection with heads 66 of the carriage 62.

The slotted connection between lever |66 and lever |68 provides for a slight time delay in carriage reciprocation at the moment of sheet pickup and sheet deposit, and to prevent sudden jars and strains when the ends of the slot |61 are reached we have provided a uid containing cylinder |1|, having one end thereof pivoted to the table frame a piston |12 movable Within the cylinder, a fluid bypass |13, and a piston rod |14 pivotally secured to lever on shaft |68'.

The swinging sheet guide 12 is actuated by rod |16 having a slotted end pivotally carried by offset pin |11 on lever |68.

Air suction means are provided by cylinder pump |18 pivotally mounted at one end to the table frame, the piston rod |19 being pivotally secured to lever |80 on shaft |8I. Said shaft is driven by sprocket |82, chain |83, and a second sprocket |82 on shaft 90. Suitable flexible conduits |84 are connected to the cylinder pump |18 and to the suction bar 63, provision being made for movement of the conduits during reciprocation of the carriage 62.A A spring |18 may be secured to the pump and to the table frame to assist in raising the pump during rotation of lever |80.

The binding means is actuated by cam wheels |85 and |85.' secured to shaft |8|, the cams |86 and |81 being adaptedy to contact cam roller |88 on rods 11 to urge said rods and the binding frame 16 gradually downward and to accelerate the upward return thereof.

The rack 86 of the flopper mechanism is suitably mounted for vertical movement and is normally urgedr downwardly by spring |89. A cam roller |90 is provided on the lower end of the rack and ridesv cam wheel |85 to be contacted by cam |9| for raising the rack and rotating the flopper shaft 84, in one direction, the spring |89 causing rotation in the reverse direction.

Obviously, all the moving parts are so arranged and synchronized that they will perform their functions at the proper time and in the proper sequence. We have shown in` dotted lines a rack |92, on which the various flat sheets may be placed prior to feeding into the machine. It is understood that any suitable rack or other means may be provided for this purpose and we do not intend to be limited to what we have illustrated.

In operating the machine, the operator takes a position in front of the introducing table 5 and places single sheets on the table positioning the sheet against the shoulder 8 and the guide 9. With the motor operating the feed belts |2 are continuously moving and at the proper moment the introducing table will be raised and the belts which extend over a portion of the introducing table 5' will contact the sheet and move it along the table. In feeding the initial sheet for each set it is not desired to apply an adhesive or carbon paper and therefore as soon asthe operator places this initial sheet on the introducing table he presses down on the foot pedal I|8 to remove the adhesive applying means from the path of the amasar sheet. AThe foot pedal will also actuatgl a Ycontrol for preventing "carbon paper feed and the initial sheet will pass through the feedingjmeans, be perforated between discs I3 and. Hand be transferred to and aligned on the receiving table 49. After this first sheet has passed the adhesive applying means and as the following sheet yis introduced, the operator releases the `foot pedal and the carbon paper feed means willremain inoperative until detent |50 is released from the drum |52 by passing out through s1ot'|5|. This will close the mercury switch |41 but will not `necessarily start the carbonpaper feedingfmeanssince positive actuation of such means is also .dependent on a sheet passing over the light lr y from the incandescent bulb |40. y

Upon release of the foot pedal and insertion of additional individual at sheets on theintroducing table the device will operate in a normal manner, that is, the sheets will be perforated, adhesive applied and when passing between the photoelectric cell and the incandescent bulbi, a predetermined amount of carbon paper will befed to the' carbon paper receiving table the amount of carbon paper fed depending on the length of the at sheet and consequently on the length of time that the light ray is interrupted.

The moment the light ray is unobstructed the carbon paperfeed will stopand the table 41-Will be quickly rocked to cut the carbon paper and raise the cut portion to close r proximity vwith the flat sheet which is in alignment therewith. At the same moment the sheet pickup or suction bar 63 on the reciprocating carriage 62, having moved to a position over the adhesive bearing edge of the fiat sheet is quickly depressed at that point by cam 10 to cause the suction bar to firmly press the sheet and carbon together against the table 41, the carbon paper adhering to ktheat sheet.

In Fig. '7 is shown a preferred method of adire-- sive application, two stripes |93 of adhesive-being applied to the at sheets, the carbon paper being affixed to the inner stripe. l

The flat sheet with carbon paper attached `will adhere to the suction barY which isy movedl across the receiving table 49, the sheets being aligned by guides l58.and 59 and binding fingers 8|),` Aand the binding frame 16 is depressed carrying with it the reciprocating carriage 62, the hOOkedpOrtions 82 of the fingers bearing iirmly again'st'thesheets,

and the suction being broken'topermit deposit of the sheets.

As additional sheets are deposited" entire re-v ceiving table the outer stripe of adhesive is pressed firmly against preceding sheetsl and aset of any desired number of sheets and carbons may be formed. f

As sheets accumulate on the receiving table 49 said table lowers automatically and is restrained against upward movement' by dog 54 which may be manually released to permit return of the table 49 to raised position when the sheets have been removed. f

Between each set, the-initial operation, that of depressing the foot pedal-to prevent adhesive applying and carbon paper feeding, is repeated. It is clearly obvious that we have provided a device in which any number of at sheets. and carbons may be assembled into r sets, 'inwhich feeding'of a flat sheet into themachinewill-insure positivel and automatic feeding of apredetermined quantity of carbon paper unless the operator desires to manually prevent such feeding, that as long as sheets are not introduced Ano car- 'bon is being fed and there is nothing Wasted.

. should also be clear that in .devices adapted to perform the generall function of our-machine Awe have provideda relativelyosimple and economical structure. o A VWe reserve vall rights to such changes in form, proportion and details of constructionas come within the scope of thesespecifications andthe f following claims. -v What we claim as new and desireto secure by Letters Patent is: f
