TYPE-WRITING MACHINE.

7 Application filed April 21, 1923. Serial No. 633,573.

T BaZZ- whom it may concern: a e it known that I, Jnssn A. B. SMITH, a citizen of the United States, residing in Stamford, in the. county of Fairfield and State of Connecticut, have invented certain new and useful Improvements'in Typewriting Machines, of which the following is a specification.

The invention relates to sheet-collating mechanism in typewriting machines.

In writing individual statements or ledger-sheets in a typewriting machine, a recordsheet is commonly employed, on which are accumulated the several entries made on the 1 entry thereon,

successive statement or ledger sheets. For

convenience, the record-sheet is allowed to remain in the machine while the statement or ledger sheets are succesively introduced and removed; means being provided for holding the record -sheet, ready for writing on the next blank line thereof, while the statement-sheet, or ledger-sheet, or both ledger and statement sheets are collated or positioned with respect to the printing line of the platen for writing at a g'ven line-p0- sition thereon. In other words, the ledgersheet, for instance, should be positioned for writing on the blank line following'the last and such blank line should coincide with the blank. line next followin the last entry on the underlying recor sheet.-

For easy insertion of the ledger and statement sheets, the feed-rolls are released.

While the feed-rolls are released, the recordsheet, which is usually wider than the other sheets, is held at its margins to the platen by spring clips or fingers. In returning the carriage after conclusion of the previous entry, the platen will ordinarily have been automatically line-spaced; so that, at the time the following ledger or statement sheet .is being positioned, the record-sheet stands ready for. writing on the next blank line thereof. A collating table for the ledger and statement sheets has heretofore been provided; 'with pins thereon whereby to impale the ledger or statement sheet on the front of the table; the-pins serving, not only as a means for aligning or s uaring the sheets, but also to hold a sheet, or instance, a ledger-sheet, while a statement-sheet is positioned thereover. The record-sheet 0r dinarily passes behind the collating table and is clear of the pins. The sheets collated on the table have been provided with rows of holes extending marginally lengthwise thereof to receive the pins and the particular holes employed, in each instance, dependv upon the position, lengthwise of the sheet, of the point at which writing is to be, commenced.

Heretofore the diameter of the holes has been such as to cause them to be graduated apart at double line-space distance; leaving suflicient stock between the holes to prevent tearing of the paper. It is, however, sometimes desired to type at every line-space position; that is to say, to do single line-space work on the record-sheet and ledger or statement sheet. In such case, the chances are eventhat the required setting of the ledger-sheet with respect to the printin line of the platen will result in placement t ereof over the impaling pins with the pins between two successive holes at single linespace distance from each, instead of in registry with any ofthe holes; thus precluding a setting of the ledger-sheet on the pins without movement of the platen. The ledger-sheet might, of course, be set up a line-space higher on the table, so as to cause holes therein to register with the pins; and, after the feed-rolls had been reapplied, and the sheet disengaged from the pins (following the collation), the platen could be turned back a single line-space, before commencing the writing, to position the proper line of the ledger-s eet at the printing line of the platen. Such back-feed of the platen would, however, return the last written line of the record-sheet to the printing line of the platen, with the result that it would be written over and and obliterated by the first line of the new entry. If, on the other hand, the ledger-sheet be set down a line-space on the table and the laten subsequently given a singleline-feed fhrward, the result will be a blank line," or break, in the writing on the record-sheet.

The object of the present invention is the provision of means whereby (instead of first falsely setting the ledger-sheet and then attempting to correct the setting by turningthe platen), the pins themselves .may be moved a single line-space distance to bring ture of the invention is the the ledger and record sheets are in proper frame of the machine,

position for commencing writing.

Features of the invention are the means for carrying, guiding, and determining the proper movement of, the pins, and for simultaneously efl'ecting such movement, of the pins at each side of the table, by means of a single finger-piece or key; this mechanism being compact and simple, and being located where it cannot foul the sheets.

The collating table is ordinarily in two sections, laterall I date sheets of different widths; and a fea provision of operating connections for the ins, which connections remain efi'ective w atever the adjustment of the table, and which are neither broken nor require any manipulation in making the adjustments of the table,

Other features and advantages will here inafter appear.

In the accompanying drawings,

Figure 1 is a view, in side elevation, and partly in section, taken on the line 2-2 of Figure 2, showing a platen-frame having the paper-controlhng devices of the present invention mounted'thereon; the impaling pins being indicated in their upper or normal position.

Figure 2 is a view, in front elevation, of the apparatus shown in Figure 1.

Figure 3 is a View, in cross-sectional side elevation, of a. part of the apparatus shown in Figure 1 showing the impaling pins as having been moved to and locked in lower position, and the actuating and locking means.

Figure 4 is a plan view, showing a-ledger or individual statement sheet; the collating table and wing-scale being indicated in dotted lines behind the same.

The platen 10, by means of its axle 11, is

journaled in the side plates 12 of a platenframe. On the axle 11 are the usual handwheels '13 and line-space ratchet-wheel 14. The side plates of the platen-frame areconnected at the rear by cross-tie 15; and, forward thereof, by rod 16. -Secured-to the cross-tie 15 is the usual rear paper guide and apron 17 for guiding work-pieces from the rear, down, around, and to the front of the platen. Front and rear pressure- rolls 18 and 19, respectively, are provided for. holding the work-pieces to the platen, for effecting feed thereof in line-space and reverse directions upon rotation of the platen. Means, not shown, but which may be of the type found in the Underwood standard tgpewriting machine, are provided for t rowing the pressure- rolls 18 and 19 to and from the platen, and also for throwing the apron 17 to and from the platen, to permit of easy movement of the work-sheets around the platen, for'the collation thereof. The usual wing-scale 20, mounted upon the adjustable to accommo has its upper edge in close proximity to the platen, to indicate the printing line on the latter. Spring-clips, not shown, but which may be of the style found in the Underwood standard typewriting machine, are provided with rolls 21, for holding the under or record sheet to the platen, at the margins thereof, against displacement, while the pressure- rolls 18 and 19 are released.

A collating table 22, in two sections 22 and 22 is mounted on a cross-bar 23, above the platen, at the front of the platen-frame. The table- sections 22 and 22 are adjustable with respect to each other, laterally of the machine, to accommodate work-pieces of different widths. Headed screws 24 hold the collating-table-sections to the bar 23, and slots 25 in the table-sections permit the adjustment of the table-sections when the screws 24 are loosened. The bar 23 is secured by screws 26 to brackets 27, set on the cross-rod 16. Another rod 28, mounted in-brackets 29 on the side ieces 12 of the platen-frame, passes throug recesses 30 in the brackets 27, and holds the latter against angular movement on the rod 16.

A work-sheet 31, which may be a ledger- 'sheet or a statement-sheet is shownv as having superposed thereon, between the same and the platen, 'a record-sheet 32. At the front of the platen, above the printing line, the statement or ledger sheet 31 is passed up, over and in front of the collating table 22. The record-sheet, on the other hand, is passed between the rolls 21 and the platen, and thence is guided rearward behind the table 22. The work-sheet 31, as shown in Figure 2, is narrow enough to pass between the rolls 21, whereas the record-sheet is sufficiently wider to be engaged by the rolls 21 and thereby directed rearwardly around the platen to its position back of the collating. When, therefore, the pressure-rolls l8 and 19 are released, the work-sheets 31 may be passed freely around the platen and onto the table 22 for collation, while the record-sheet is held against displacement by the rolls 21. It will be understood that several work-pieces 31 may be collated on the table 22. There may, for instance, be not' only a ledger-sheet or an individual statement-sheet, but there may be both a ledgersheet and an individual statement-sheet, and these sheets may be collated with respect to each other, and with respect to the recordsheet, in a manner hereinafter described. An auxiliary table, not shown, may be provided for holding the record-sheet separated from the other sheets at the rear of the platen, so as to pennit easier insertion of the ledger and individual sheets. Carbons will, of course, be inserted between the sheets; and the carbon between the recordsheet and the work-sheet next thereto may of the slots .38.

i the rear be secured to the record-sheet by having-its 'ng' are bifurcated, as at 45, each loosely to enupper leading edge turned over the lea e ge of. the latter in a well-known manner. The carbons for the ledger and individual statement sheets may also be aflixed to such sheets. 7

As shown in Figure 4, the work-sheets 31 are provided, adjacent each margin thereof,

with a rowof pin-holes 33. These pin-holes are indicated as at double line-space dis: tances apart. Below the space, which is provided for the headin holes 33 have gra nations in registration therewith, numbered 1, 3, 5, 7, etc. Other graduations, numbered 2, 4, 6, etc., indicate single line-space distances from the next preceding hole 33. In Figure 4, the sheet is shown as positioned for writing on a line indicated by the graduation 10 between two succeeding holes 33; the shown as immediately above the upper edge of the wing-scale 20, which, as hereinbefore noted, denotes the rinting line.

At each side 0? the two-part collating table 22, and projecting therethrough, an out from the front surface thereof, is a pin 34 arranged to be registered with any selected one of the holes 33 in the correspond ing series, and to be passed through such selected hole by pressing the work-piece to the table. The pins 34 are of a size to' nicely fit the holes 33 and to hold the paper frictionally against displacement. There being a pin 34 at each side of the table, when impaled upon the two pins, through holes bearing the same number in the scales on the paper, will be aligned or squared with respect to the printing line and with respect to the other work-pieces. The pins', however, have the further function of holding a work-piece thereon to release both hands of the operator for collating another workpiece with .respect-to the work-piece then on the pins.

The ins 34 project through-vertical slots 35 in t e table, and, at the rear face of the table, are fixed, each on a slide 36. ZIhe slides 36 are held to the table 22 by headed screws 37, which pass through slots 38 in the slides. The movement of the slides, with the pins 34, on the table 22, is determinedby engagement of the screws 37 with the ends The slots are of such length as to permit the pins to be moved up an down on the table a single line-space distance. The left-hand slide is shown as having an ear 39, turned rearward thereon. In

the edge of this car are two notches 40 and 41 also centered a single line-space distance apart.

face of the table 22', by co-operation with one or the other of the notches 40, 41, holds the slide in its upper or lower position, when the same is thrown to such position. Each slide has also another ear 44,

of the work-sheets, then graduation 10 being a worksheet,

.belowt This movement of the pins is effected by 110 osition through the connections A sprmg-detent42, pinned at 43, to-

turned rearward therefrom; and the cars 44 gage a pin 46. Each of the pins 46 is fast to and projects laterally from an arm 47, se cured by a set-screw 48 to a rock-shaft 49. The rock-shaft 49 is journaled in the brackets 29 on the end plates of the carriage, and also passes through cuts 50 in thebrackets 27, thereby further supporting the latter. Fast to the rock-shaft 49 is a finger-piece 51, by means of which the shaft may be rocked with the arms 47 and the pins 46, to cause the slides 36 to be moved up or down. Since both the slides 36 are thus operable together from the shaft- 49, only one detent-device 42 is necessary. It will be noted that the pins 46 are of such length as to permit lateral adj ustment'of the sections 22 and 22 of the collating table without disengagement of the pins from the ears 44 on the slides.

Assume that a ledger-sheet 31, when properly positioned on the platen by means of the wingscale 20, shows one of the odd numbered graduations in registry with the printing line. In this event, the pins 34 register with one or another of the holes 33, and the sheet may be impaled upon the pins by pressing the same against the table. On the other hand, let us assume, as shown in Figure 4, that, when the sheet is in proper position, with respect to the printing line, a graduation, such, for instance, as the graduation numbered 10, registers with the printted lines at 34, Figure 4, the impaling pins will fall between two adjacent holes 33, and the sheet cannot be impaled upon the pins by pressin the same to the table, or without disturbin the position of the sheet on the platen. n such case, the pins 34 are moved from the position shown in Fi they re ister with the holes in t e sheet next e dotted-line positions of the pins.

throwing the to Figure 3 heretofore escribed. The pins being thus brought to Figure 3 position, the sheet may be impaled and held in place in the-usual manner by pushing the same over the ins to the table. ,The individual statement-s eet may then be set upon the pins in registered relation to the ledger-sheet. During finger-piece 51 from Figure 1 d this time, the record-sheet 32, as hereinbefore stated, is held in place by the rolls 21. The collation, however, being completed, the pressure-rolls 18. and 19 are applied. The sheets 31 on the pins maythen be pulled out to the position indicated in Figure 1, to per- "mit line-space movement of the work-sheets,

and the writing then commenced. The rounded ends of the pins 34 will cam the work-sheets off of the same, to permit of line-space movement of the sheets during the writing.

line. In this event, as indicated in dot-'1 ure 4, until Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
