407,658. Divided and this application August. 5,1942. Serial No. 453,730 I I 16 Claims. (cider-n14) Thisinvention relates to typewriting machines, and more particularly to mechanism for feeding and positioning continuous webs comprising a plurality of connected form sheets. 1

This application is a division of our copending application, Serial No. 407,658, filed August 20,

1941', now Patent 2,311,227, issued February 16,

In typing a plurality ofsimilar. invoices, checks, or similar forms, it is common practice to supply a continuous web or sheet comprising a plurality of serially connected individual forms which are fed successively to and then beyond the printing line as: following forms move into printing position. The individual forms comprising the continuous webmay all be. the same, so that the beginning or. first: typed lines on allthe forms will be equally spaced below the topsof the respective. forms. The distance between the last line of. typing on each form and the: first line of typing onthe next succeeding form may vary, depending upon the typing of diiferent numbers of lines on different forms, but in any event it usually is the equivalent of. a rather large number of the spaces between individual lines, i. e.,. line spaces. In

theinterestofease andrapidity of operation in the typing of such forms, it is desirable to provide mechanism including a member a. single actuation of which, following the completion of typing on one of a series of connected forms and regardless of: the number of lines typed on. that form, will advance the web to position the next succeeding form for receiving its first line of typing in the same relative position, on the newly positioned form, as the first line of typing on the completed form. Suchmechanism, broadly consideremhas been proposed heretofore, and one of the: objects of the present invention is to provide.

for easily varying or. selectively" determining: the

feedingcapacity orli-miti-soas to. makeit readily The: first such. condition may be, for example, for. feeding. thezweb just the correct amount to. position theleading form. toreceive the firstrline of typing, and the second condition may be; for thereafter feeding the web a, different amount following; thecompletion of typing. oneach of the forms-topositiomthe next succeeding form to receive, its: first. line .of

typing; In the aforementioned patent,;fithe-setgranted tingiof'the feeding capacity or limit is determined by adjustment of a selective stop, device carried by the handle whichis. operated to drive the feeding mechanism. l

*Another object of: the-present invention is to provide another improved construction including a :feeding capacity determining device in which a'selectiv'ely' operable stop is carried by the frame but which nevertheless is adapted to be placed in selected: position. by means carried by the operating handle.

Aiurtherobject is to provide a simplified complemen-tal web feeding mechanism. 1 Other. objects will become apparent from a reading 'of the following detailed description, the appended claims, "and the accompanying drawings, in-which:

Figure 10 is a section on the line Ill-I of Figure 9; and

Figure 11 is a fragmentary, transverse, sec- 7 tional view of a web-feeding cylinder or platen, pressure rolls, and paper pan.

The drawings show only such parts of conventional typewriter construction as are necessary for an understanding. of the manner in which paper-feeding mechanism embodying the inder 1 is fixed. Front and rear extension posts 8 and 9 projecting outwardly from the right-hand end plate 4 serve to mount a supplemental. end plate Illv which, asexplained hereinafter, .sup-

ports the feeding. mechanism embodying the invention. The shaft 6 is extended :through and beyond. the supplemental. endplate 1.0. and its projecting end is providedwith the usual platenrotating finger knob ll. As shown'in Figure 6, the. cylinder. shaft -6 is equipped with a linespacing ratchet wheel l2 adapted to be yieldably held at line-spacing. intervals by means; of a pawl l3 pivoted as at M on the left-hand carriage end plate .4. A spring l5 connectedwto the pawl l3 and anchoredon the carriage end plate 4 at a pointnotshownurges-the pawl yieldably in aclockwise direction to effect yielding contact of the pawl roller l 6 withftheteethof the-ratchet wheel l2. This line-spacing ratchet anddetent -mechanism is of known form, being standard equipment in the Royal typewriter. As is well known, it serves toyieldably determine the successive. definite. positions in which, theplatenor cylinder 1 is yieldablyheld .for' determining predeterminedline spaces. The typewriter may also be equipped 'with' a. known or suitable form of combined carriage return and line-spacinglever (not shown) adapted todrivea pawl engageable with the teeth.of.the-ratchet wheel l2 for effecting line-spacingasanjalternative to turning the platen orcylinder bymeans of the finger knob I l. As'vshown-in Figure 11,- a paper pan II. pro- .jecting downwardly from the rear of the platen and thenunder the platen towardthe front of theilatterisjformed with openings 18 and H! for accommodating rear and front pressure rolls 20 and 2!, respectively, adapted to cooperate with .the platen I for feeding the work sheet C from the rear of the platen, under it, and then up in front of the platen so as to be disposed at the printing line to be, impacted by the type bars.

With the exception of the supplemental end plate l0 and its mounting onthe carriage, the parts thus far described are of known form and relativ arrangement, and do not constitute the The invention comprises other parts to be described and combinations of such other parts with each' other and with the parts referred to above.

Before describing in detail the illustrative embodiment of the invention, and in order to facilitate an understanding of the detailed description which is to follow,'reference first is made to the diagrammatic showing in Figure 4, which indicates the desired steps of feeding which the mechanism is intended to accomplish. The work sheet or web C comprises a plurality of serially together; the form 0 three typed lines; the form c three typed lines; the form 0 five typed lines; and thefcrm c three typed lines. It is desired to advance the web with certainty and rapidity to" exactly the right position for receiving the first line'L of the form 0 and then with equal ease and rapidity to position the successive forms for receiving their initial typed lines regardlesss of how many lines have been typed on the preceding form.

the ,timeits leading edge first engages the platen and. rearpressure roller 29 as shown in Figure 11 until it is in position for receiving first line L on the leading form 0 will be a fixed'amount,

and, for the purposes of illustration will be assumed to correspond to twenty-four line-spacing increments. Similarly, the distance 3 between the first typed line of each form and the first typedline of each succeeding form will be fixed and will be assumed to be equivalent to twentyone line-space increments. The rotation of the platen l for, lineespacing the web for the second and other additional lines on each sheet is effected by means of, the usual line-spacing mechanism, such as th finger knob I I or a combined carriage return and line-spacing mechanism (not shown), The feeding of the Web for moving it fromthe'posi-tion shown in Figure 11 to the poshtionfor receiving the typed line L on the form c is accomplished by a single actuation of an opcrating member 22 having a handle 23, Advancing of. the web from the position occupied during the typing of the last line on any form to the position'for receivingthe first line on thenext form, also is accomplished by-asing1e actuation of :the member 22; and, inasmuch as this continuous feeding movement will differ from the movement which first positioned the .form 0 for the reception of the line L a selector device 24' having a finger piece 25 is providedforselectively determining the limit of movement of the -manually operable member 22, -As hereinafteris explained in more'detail, the finger piece 25 of.

the selector device 24 is depressed, and the mem- ..ber 22 rocked forwardly to the limit of its travel to position the form 0 for the reception of the .line L whereas, for'advancing the Web from the l0 and abracket 28 secured to the end plate I0 byscrews 29."

The stop 50 previously: referred :to is carried by a stopfimounthfiz rockable .on the platen shaft-5 and yieldablyheld in'adjusted position by a friction washer 63 interposed be. tween the hub- 64 of the stop mount 62 and the hub of the cylinder knob ll. 'Lugs 65 and '66 on the stop mountfiZ are cooperablewith a pin 61 on the -end plate Hi forlimiting the shifting of the mount'62. an arm 68 extending from the stopmount 62 carries a pin 69 which is adapted to be operated by'the selector 24 in amanner later to be described for shifting the stop mount from the position shown in-Figure 2 to the posithepath of the nose end of the pawl 38, the ar- 'rang'ement being such that, as soon as thenose end engages the stop 58, forward rocking of the lever 22 is terminated. When it is desired to increase the stroke of the lever 22 so as to providean increased total feeding of the web, the

stop mount 62 is shifted to the position shown inFigures '7 and 8, wherein the stop 50 is placed further away from the axis of rotation 'of the ratchet wheel and pawl and in position to be engaged, not by the leading end of the pawl nose, but by'a portion of the pawl intermediate the nose and'pivot 31, as shown in Figure '7. Thus the lever 22 'and' ratchet wheel 30 can move further before being arrested by engagement of the pawl 38 with the stop 50, and this additiona1 movement provides for the increased feed necessary to position the first or leading form e of the web for receiving its first line of typi -L'l;

For moving the stop mount 62 to the position shown in' Figures 7 and 8, the selector 24-is provided with -slots "Ill cooperable with screws H and 12 for mounting the selector to slide inwardly and outwardly on the lever 22. A spring 13 interposed between a pin 14 on the selector and the U screw'TZ fixed to the lever 22 urges the selector outwardly. At its inner end, the selector is formed with a stop-shifting arm 75 which is adapted, during anoperating stroke of the lever and when the selectoris pushed inwardly, to engage the pint!) on the stop mount 62 to rock impositively couples the hub of the platen knob H to the mount 62 for shifting the latter to its FigureZ position and holding it there in response to web feeding movement of the platen. The selector ispushed inwardly for shifting the stop mount 62 only when theincreased total web feeding 'is desired. When the selector is left in its normal position outwardly with respect to the lever '22, the arm 75 will not engage the .pin 6!! of the 'stop'mount 62, and the mount will be maintained in its Figure 2 position.

By adjusting the position of the spacing variation plate 4| and determining its setting by reference to the position of the pointer 46 onthe scale 41, the total amount of web feeding which can be effected by operation of thelever 22 can be varied according to the kind of forms to be typed upon. The setting of the plate 4| shown in the drawings could correspond, forexample, to a total feed of twenty-one line spaces when the selector 24is not pressed inwardly, and a line spacing of twenty-founwhen the selector has been pressedinwardly to shift thestopmount 62 In operatiomthe parts will be in'thepositions shown in Figures-1 and 2 when the web C first is placed in the position shown in Figure ll with its leading edge just contacting the rear pressure rolls 2!) and platenl. Toposition the leading form 0 tofreceive its first line of. typing L the platen must be rotated an'amount corresponding to twenty-four line spaces, correspondingtothe developed. distance S in Figure 4. l The'operator holds the selector pressed inwardly by the same hand which-grasps the lever 22, and then pulls the lever forwardly until it is arrested by engage ment of'the'pawl 38 withthe'stop'iil, as shown in Figure 7. During the latter part of this movement :of the lever th'e arm'15 on the selector will have engaged the pin 69 on 'thestop mount 62 so as to shift the'latter' and thestop 5!! to the positions shown inFigures 7 and 8, thereby permitting the platen to be rotated an amountcorresponding to twentyfour line spaces.

The four lines are then typed on the form 0 the line-spacing for the three lines succeeding theline 'L being effected by turning the knob.

H or operating the conventional line-spacing lever (not shown); The rotation of the platen during the line-spacing for the last three lines on the form'o will cause theshield 5|"to move around with the ratchet'wheel 30 an amount corresponding to three line-spacirig increments; Therefore, when the lever 22is moved forwardly on its next web feeding stroke to advance the form 0 into position forrreceiving its first line of typing L ,'the pawl 38 will ride idly on the shield 5|for a distance corresponding to three line-spacing movements of the platen,and'-'wlll then drop down into engagement with the ratchet wheel, so that, during-the succeeding part of the working "stroke of the lever 22, the'platen will be rotated an amount'cor'respon'ding toeighteen line spaces, rThis feeding, taken in connection with the feeding accomplished by the three pre ceding line-spacing increments effected byrotation 'of the knob' H or actuation of the conven tional line-spacing lever, will amoun'tto a total advance corresponding to twenty one linefspacing increments, the equivalentof which'isindicated at s in Figure 4, this-beingthe distance between-the first lines of typing L andL on the adjacent forms c and 0 During this stroke of the lever 22, the selector 24 1s not pressed downwardly, .and accordingly the'selecto'r15 does not engage the pin 69 On the stop mount 62.

Consequently, the stop mount has been left in the position-shown in Figure-2 so as to engage the leading end of the pawl nose. When the cylinder or platen is turning to feed the web following the typing of the line L on the form 0 the spring washer 63 will cause the stop mount'6'2 and stop '50 to be returned to their respective positions as shown in Figure2. Consequently,

'whenthe lever 22 is operated again (without the selectorsbeing pressed inwardly), the stop 50 will be positioned to limit the total feeding to an amount corresponding to twenty-one line-spacing increments. Ordinarily the selector is moved inwardly to shiftthe stop 50 to its Figures '7 and 8 position only when the first or leading form 0 is to be brought to starting position. Thus the forms 0 c c and'c will be brought to starting position and line-spaced individually without pushing the selector in at all. However,- it is evident that the selec tor devicealso could be used in the case of forms which, within the'continuous webor sheet itself, vary as t'othe distance between initial lines of typingion adjacentforms.
