This invention relates more particularly to the equipment'of adding and listing machines and'the like l'for'handling various work sheets such for example, as ledger *sheets, bills,-;record or proof sheets and the like.

It has been customaryheretofore to. as-

semble: superimposed work sheets-in proper relation2 around-the rotatable platen of :addingmachines,"typewriters.and the like by separately (insertin the sheets andpositioning them afroundt e platen, the first sheet. beingretained in "adjusted position while the'second isbeing i'nsertedand properly "collated -with. =respect.to the first sheet. \V hen three w rk sheets: are to be printed upon .the first-and second sheets, which are separately -.a.-djusted, are restrained from moveinehtrwhilelthe third is being inserted --and-=adjusted. -Various means have been employedfor separately feeding the sheets into :collated'positionspn the machine and restraining movement of one is being positioned. i

251 1 The rinci a'l ob'ect of'mv'invention is feeding means.

to provide equipment whereby the work sheets \Inay becollate'd in a work-sheet holder while. out-iofpthe machine,;-the holder being" readily transferred from a collating =table.to"the 'niachineland adapted to hold .sembled relation in the work-sheet holder.

The latteris provided with retaining devices for holding the work sheets in their adjusted positions relative to each other. The holder is transferredto the machine and is so supported thereon that the work sheets are located between .the platen and cooperating feed rolls, the platen being then in its rearposition to permit ready insertion of the holder and sheets. hen the platen'cr adle is rocked forward to bring the platen into print-in position and into cooperative relation with the feeding rolls tae retaining device on the holder are automatically disabled by an arm on the platen cradle so that the collated sheets nutty be while another holder as on the line 'oonm'rmeimnrrmsnr roa ADDING MACHINES AND THE LIKE.

fed in unison by the platen'and rolls. One ofthe sheets, for examplefthefi ASSIGNOR TO BURROUGHS ADDI NG MA tally or proof sheet,- maybe curled around i and fed by 1 the platen in the usual way.'. Another object of the invention is to-pro 0o vide an improved work-sheet holder adapt-* ed to retain the work sheets collated con 1 dition. i

Still anotherobject ofmy invention-is to provldean improved collating table upon which the work-sheet holdermay be supported iii-proper position and which is provided with means facilitating the positioning of the sheets with Othelt;

With the above and incidental objects in view, the invention consists in certain novel features of construction and combirespect to each" nation -0f parts, the essential elements= whereof are recited in the appended claims and a preferred form of embodiment of illustrated-in full in the accompanying drawings which form part of thisspecification. I

The invention is shown herein- 2.5 applied. to the well-known ,Burroughs adding and listing machine, but,it' is understood that it is not limited inits gapplica-tion thereto as'it is adapted foruse on other types of.-adding 1 and listing machines as well as on typewriters and thelike. My invention is also adapted for use inhandling ,various bookkeeping systems, but, for convenience, I will describe its usein connection with handling the boolrkeeping work 'ofcustomers accounts, in which case three sheets (the cus tomers bill-101' statement, the customers ledgersheet and the proof or tally sheet) are printed upon, the statementand ledger sheet being collated on the collating table, while the proof sheet is curled about'and-fed by the platen in the usual manner.

In view of the fact that the Burroughs machine is in extensive commercial use and is well known, it will be wholly unnecessary to describe the machine properpr to describe the carriage equipmentin any detail. Referring to Fig. 1, the adding machine, designatcd generally by the reference numeral 20, is supported on the usual stand or rack 21. The usual numeral keys 22 are employed for setting up the various items and controlling the extent of movement of the customary actuating levers which carry type plates 23 (Fig. 8) for presenting items and totals to the printing line. A back panel 24 (Figs. 8, J and 10) of the supporting frame work of the machine has secured to it.

the usual track 25 upon which the laterally siiiftable paper carriage 26 runs, the track and carriage having the usual raceways in which roller bearings are mounted. A rotating platen 27 is supported in the rock frame or. cradle 28, which comprises end plates 29 journaled on a cross-shaft 30 carried by the end plates of the carriage 2G. The cradle 28 carries a paper support or back 32 upon which are mounted laterally adjustable guides as shown or described more fully in my Patent No. 1,208,375,

11, the sheets being shown clamped,

.platen with the usual pressure rolls 35. The forwardiends of the proof sheet and carbon.

are guided by a floating pan 36 carried by the platen cradle, and are also guided by wellknown guide fingers 37, supported at .their rear upper ends on a cross-rod 38 and having their forward lower edges offset to slightly overlap the upper forward edgeof thefioating pan 36. -T he rod 38 is supported in extensions of the side plates 29 of the platen cradle. Upon each operation of the machine, the platen 27 is rotated to linespace the proof sheet, and also thestatement and-ledger sheet, as will be described later,-

the platen being rotated by the usual linespacing mechanism which is only shown generally in Fig. 1 and which is designated by the reference numeral 39. The pressure or feed rolls are supported by levers 10 and are pressed against the carbon and: proof sheet by the usual springs 41, (Fig. 9).as is customary in'rthis type of Burroughs machine.

The platen cradle 28 may berocked so that it is either in its forward printing position, shown in Fig. 10, or in its rearward position illustrated in Figs. 8 and 9. In order to hold the platen firmly in its printing position, a' roller 42 (Fig. 8) is firmly held against the cam edge 43 of the left hand ,plate 29 by a spring 44 connected to the arm 45 carrying tne roller, this construction being also common to this type of Burroughs machine.

In order to latch the platen cradle in its rearward position I employ the latching mechanism illustrated in Fig. 8, the platen being there shown latched in its rcarwardly tilted position by a latch 46, pivoted at 17 to the right-hand vertically extending side plate or arm 48, the arms 48 being secured to the side. plates of the paper carriage. The vertical arm of the latch carries an operating finger piece 49 and is provided with a slot. 50 through which the shouldered stud 51 projects, the stud serving as a stop for limiting the forward or releasing movemcnt of the latch. The rear end of the horizontal arm of the latch has a shoulder 52 which, when the platen cradle is tilted back, engages a headed stud 53 on the right side plate 29 of the platen cradle, the latch being moved to such latching position by a spring 54.

In addition to the paper table 32, the paper carriage is provided with ;another paper guide or plate 57 which extends above the platen and has its upperend rolled about a cross-rod '58, carried by the side arms 48, wliilethe lower edge is curved'forwardly to;avoidr-inter-ference with the-platen when the, platen is; in its printing position. A cross-rod 59 is supported at its ends in rearweirdly extending arms; 60 integral with the 59 projects through rcarwardly extending'ears- 51 0f two paper:

guides 62, best shown in Fig; 2. As'sliown in Fig-s8 and 9, arms or yokes 63 are slid- :iblyanounted on the rod-59 andthe. ears 61 have heys63iprojecting into a groove on the rod- 59 to prevent rotation These yokes are slidable with the guides 62 and springs-Mare coinpi'esed' between the arms 63 and=the rear sides-of. the guides-62, thereby. normally pressing the forward cam edges of the side arms of the yokes 'against the rear sides of the guides to cause the keys (31 to bind in the groove in the rod 59 and thus frictionally retain the guides against at iital displacement; The sides 65 are provided .with slots 66. for the reception oi". projecting portions of the detachable holder -66 in which the statement and ledger sheet are collated, as. will be described later, and wliich is illustrated diagrammaticallyin Fig- 1 F v I" The worl-z-sheet holder is shown-in position on the machine in'Fi 9-;and itwill benoted that whentheiholder' is in the machine, with the bill B and ledger sheet-L,

together: with an interposed carbon C held in position thereon, and the platen cradle in its .rearwardly tilted position, the lower portions of the bill and ledger-sheet are guided by a table GT, which is niounted on the and screws '70. The table comprises acurved plate? 1' and two parallel plates 72, which are supgiortedon and over the edgeportions of the lower plate 71 through spacing collars 73 located along the edges of the plates.

Equaliy spaced along the upper edge of theplate 71 are four spring-pressed feeding i'olis 7 1, the rolls being mounted on arms 75 whi h are engaged by leaf springs 'l'fiunorinaliy tending to press the rolls towards the platen. It niightbc stated here, sheet and bill have been positioned in the machine and the platen cradle is'rocked' forwardly to the printing position shown in Fig, 10, the ledger sheetand bill. are relcascdlrom the work shcetliolder, as will be described presently, and these work sheets are then gripped between the platen and the feed rolls 74 and are fed in unison thereby when the platen is rotated.

The carriage equipment, described above, is very similar to that more iully shown and descrihcd in the copending application filed by Arthur S. Trew on July 3, 1924;, and

The arms 84 pins .85 projecting..- tlirough registering slots'89-fforined in the platcs'l'SJ and 791 li ote'd at; on the plate 78 is a latch 91 having-a finger piece 92 on its longer arm-1.;- .ltsshorterarm-has a struck-up ear; which 'IS PiOVldGd'iW lllll a shoulder 93 and -a spring 95 i's secured atone-end to the latch and at its'other end to theright-hand arm 81L. I I; f

ls hile theledger sheet and statement are being positioned and collated in the holder,

the pins 85 andpads 86 are in the elevated lmliltloli illustratedin Fig. 4 and are retained in such position by en agement of the shinilde'r 9:5 with the underside of the rightlmnd arm 84-. A projecting nose 93 then x-ngages the side edge of this arm to limit 115 the increment of the latch'9l in one direction while a pin 92' liinitsmiovemcnt oftlic latch in the other direction After the ledger sheet and the statement have been ,propei'iy positioned. the latch 91 by he finger-piece 92 to carry the shoulder 9-; from under the arm 84, whereupon a spring 95, compressed between the plate 78 and the upper arm of the lever 88, rocks the arms Stand shaft 83 to-niove the pads 86 into tirni engagement with the work sheets to press them against the plate79, as shown in Fig. 5. The pointed ends of the pins 8;; pierce the work sheets and thus the 1.: is moved pads and pins hold the work sheets in then-U holder and the ledger sheet and statement in the positions illustrated in Fig. 9. When the platen is moved from its-rear position, shown in Figs. Sand 9, to its tron, shownin :Fig. 10, adog or arm 97, se-

cured to the :shaft 38, is moved through the slots 89 and into engagement with the rear side of the longer'arm of the lever 88, thus rocking the lever shait 83 -and.arms 84 in opposition to the spring 95' and thereby raising the pads 86 and the pins-85 from contact with the statement; In'this'way the ledger sheet and the statement are released from the work-sheet holder and they may then be fed by rotation of the platen, the roll 74 then being in contact with the statement. Thus the ledger sheet and statementsheet, as well as the proof or record sheet, are fed in unison by rotation of the platen and the collated condition of the ledger sheet and statement is maintained.

When the platen is moved to printing position, the armor dog 97 rocks the arms 8-1 to move the pads 86 and pins 85 out of engagement with the work sheets but not sufficiently to permit the shoulder 93 of the latch 91 to snap under the righthand arm 84 so that when the work sheets are to be removed from the machine the platen cradle is rocked rearwardly carrying'the dog 97 out of engagement with the lever the spring torock the arms 84 and move the pads 86 and pins 85 into engagement with the work sheets in the work-sheet hold er. Thus. when the platen is moved away from the feed rolls 7 1, the ledger sheet and bill are again clamped in the work-sheet holder before they are released from the platen and feed rolls 74 and may be removed from the machine with the holder. Then to release the work sheets from the holder the arms 84 may be rocked manually through the lever 88.

('ollvuing table.

Mounted on one of the side bars of the stand 21 is a bracket. 98 1) which is firmly secured in position on the bar by any suitable means. .The bracket 98 carries a vertical pin 100 to which a split collar 101 is secured. The collar carrie a laterally extending rod 102 on which is secured a yoke 103 (Fig. 12), the yoke being secured in adjusted position on the rod 102 by means of set screws 108 carried by the collars on the arms of the yoke. Secured to the yoke printing posi- 88 to permit which three bolts 108 project. A triangular- 1 and 12) through shaped finder plate 109 is supported along its left-hand edge on bolts 108 project through transverse slots 110'in the finder plate 109'to permit lateral adjustment of this: plate.'--'Mountedon the left-hand end of the finder plate is a strip 111 which supports a second finder plate 112. Two elongated slots 113, extending tit-right angles to the slots 110, are formed in the plate 112 and permit adjustment of the plate. :The finder plate 109 has an' opening 114 and thefinder plate 112 has a finder houlder 115.

In order to collate the-ledger sheet and he statement, the ledger sheet L is first the bar 107 and the placed on the collating table and under the piate 109, the rear portion of the ledger .-.heet being inserted in the work-sheet holder.

The left-hand edge of the ledger sheet is with the right-hand brought into contact edge of the strip 107 and also with the rightband edge -'of the left-hand spacing strip 80 on the holder in order to align the ledger sheet straight in the holder. Riveted or otherwise secured to the strip 107 is a spring arm 10? (Figs. 1 and 7) carrying a pres sure pad 108', the arm being pressed down by the finger of-the operator to force the ad against the ledger sheet and hold it while the statement and carbon are being adjusted.

The shaft 83, mounted on the holder, is provided with an arm 116 provided with a downwardly extending guide lug 117 which has its lower end curved so that when the ledger sheet is inserted its rear end engages the curved edge of the guide and is defiected downwardly as indicated in Fig. 4. The last line printed on the ledger sheet is brought into line with the straight edge 118 of the opening 114. The statement B with the carbon C is now inserted over the plate 109 and under the finder plate 112 with their left-hand edges in engagement with a vertical flange 120 on the plate 109 and also in engagement with the side of the guide lug 117. The last line printed on is brought into alignment with the shoulder 115. The plate 109 is adjustable laterally, due to the slots 110, and the arm 116 may be slid on the shaft 88 and secured in adjusted position thereon by a set screw 116, in order to accommodate statements of diflerent widths. \Yhen the latch 91 is tripped and the arm 116 rocked to the position shown in Fig. 5

and when the shaft 83 and arm 116 are rocked by the dog-'97, upon movement of the platen to printing position, lag 117 is not-moved sufficiently to engage These work sheets and hence-cannot interfere with the feeding of the work sheets by the platen.

" Modified form, of z oi'lli-shecz fielder.

I-- have' 'illustrated a modified form of worksheet holder in Fig. 11 and Figs. 13 to 16. The frame of this holder comprises

parallel plates

78 and 79 as in the preferred .form.-' In this modified form two strips I25fof spring metal are riveted or otherwise'seeured to the plate 78 and their forward ends':are provided with inwardly ezitendingpoints 126 and 126,"which are adapted to enga e and retain the work s'heetsi-incollate 1 condition. Levers 127 and 127'are centrally pivoted on the plate 78 and their'respective outer ends are adapted to engage with the lower inclined or cam edgesfof downwardly extending flanges 129 formed-onrthe respective strips 125. The inner end of the lever 127 carries a pin 128 projecting into a recess formed in the inner end ofthe other-lever 127. A spring 131, connected' 'at oneend to the lever 127, tends tohoid the levers-in the positions shown in F 11 so-thattheir outer ends are out of contactwith the flanges 129, as indicated in Fig. 14. Theinner end of the lever 127 carries a downwardly projecting stud 132 in front of which projects one end of the lever 133 pivoted at 134 to the plate 78.

The right-hand end of the lever 133 is of irregular shape, being provided with a rearwardly extending portion having a vertical linger-piece 135 and with :1. forwardly extending portion provided with a slot 136 through which projects a stud 136 in order to assist in guiding the lever in its move nients. This forwardly extending portion is also provided with an ea 137 from which laterally projects a roller stud 138 e. :tcnd ing over the slots 89 formed in the

plates

78 and 79. Pivoted at 140 on the plate 78 is a latch 141, the rear end of which projects beyond the holder in order to permit manual operation of the latch. A leaf spring 142 engages the latch and tends to rock it in a clockwise direction.

While the ledger sheet and statement are being adjusted on the collating table, the parts are in the condition illustrated in Fig. 15, the

points

126 and 126 then being elevated out of engagement with the work sheets. At this time the forward end of the latch 141 engages behind a shoulder 145 on the lever 133, thus latching the

levers

127 and 127 in such condition that their outer ends are under the forward ends of the flanges 129 to hold the forward ends of the spring arms 12:? in elevated position with their points 12-6 and 126 out of contact Willi the ledger sheet and statement.

Th:- latch 141 is now Ma -pod by the operator, whereupon the spring 131 moves the parts to the positions shown in Figs. 11 and 14, in which condition of the parts the outer ends of the levers '127'and 127 have-*been moved rcarwardiy out of engagement with the flanges 129, so that the forward ends of the strips or arms 125 spring downwardand thu cause their

points

126 and 126 to'partially pierce the work sheets and interposed carbon. The worlesheet holder, with the work sheets held in position, is nowtransferred to the machine, and-when the platen is moved to printing position the dog-97 (Fig. 15)- which is similar to the dog"* 97 shown in Figs. 8, 9 and 10, is projected through the slots 89 and engagesover'the roller stud 138, forcing it downwardly with the result that the lever 133' is rocked clockwiseto the position sh'own'in F igf16. It will be noted, by observingthis figure, that the lever 133 is not rocked suflieiently by the dog 97 to permit the latch 141 to snap behind the shoulder 145, sothat when the dog 97 is moved out of engagement with the roller stud 138, the spring '131 rocks the levers 127-.and 127' to raise-their outer ends whereupon the points l26 and 126' again pierce the ledger sheet and statement which may then be removed-from the machine with the work-sheet holder. The ledger sheet and statement may next be released from these retaining devices by man'- ually operatng the lever 133 which is then latched in releasing condition by'the latch 141.

An arm 149 (Figs. 11, 14c and 15) corresponding to the arm 11(3 of the preferred form, is loosely mounted on a pin 150 and is normally pressed against the plate 78 by a leaf spring 151. The guide lug 117 on the arm directs the rcar or top edge of the ledger sheet downwardly when (he ledger sheet is inserted in the holder and the left-hand edge of the statement engages the side of the lug to aid in aligning the staten'icnt. The arm 1 19 is spring-pressed against the plate '78 so that it may yield when the ledger sheet and statement are fed by thev platen in case there is undue friction between the ledger sheet and the guide lug 117, and thus the arms 149 does not interfere with the feeding movement of the work sheets.

It is to be understood that thecmbodiments of the invcntion hcrein described, are susceptible to various modifications without departure from the scope and spirit of the invention as defined in the appended claims.
