V. B. ROUILLOT. TYPE WRITING MACHINE.

APPLICATION FILED JUNE @1914- 1916. 2 SHEETS-SHEEI l.

INVENTO R Patented Jan. 4,

I raazz whom army amm- I 'Be it km n'that;L-VtoronB. R UILLOT, a citizen "of the" United States, residing in Haddonfield,in the county of Camden and, State of New Jersey, have invented certain new and useful Improvements in Type- WVriting Machines, of which. the following isLa specification. v

This invention relates to the class of type writing machines in which writing'i's done upon a web or webs led from a roll or rolls of'paper, and in whichthe'heavy rolls are supported upon a stationary frame, instead of being connected to the letter tee'ding-car- :riage of the typewriter to travel therewith. One'of the objects of the invention is to operatlon of turning the platen, While the provi'de'a new and desirable arrangment of the rolls or spools,and means for leading the web or- -webs to the platen on the typewritei' carriage.

TlllS :diagonal turning bar is connected to travel i-wviththe typewritercarriage, and itself is track;

One or more addi wlllOIlEll rolls may be mounted above or below the firstiroll and the. web led up or down therefrom to join the "web running fronrthe first roll so that all ofthe webs pass and turn foyer the turning bar and run to the Ytypewriter platen as though they were a -.single'web..

. Aslthe carnage trat-els to andfro, there is 5lliz1.bl6 "t,O- occur 'aslack in the web between the spool andjthe-diagonal turn ng bar, this slaok occurring when the carnage 1s running in letterfeeding direction, and is especially noticeable when the carnage has completed "the line ofwriti-ng. In order to counteract Lthe tendencyof the slack orsag in the web to; cause the same to sllp edgewise baclg it "wardly alongthe turhingbar, there is provided gripping means upon a. supplemental "carriage; whereby the-web is held against [such edgewise creep ng saidgr pplng means being provided between-the spool pools land the diagonal turning'ban .Th s etzectis produced by means-of} parallel. rolls TYPE-WRITING ivreceizun Specification of Letters Patent. 1 ygt' f fi 3 ,1 ,4 g 1 Application filed June c.1914 Serial No. 843.338.; I

the carriage to hegina new line, the we bite web is slack, and pulling the Web off the spool after the linespace. operation is completed, presents advantages,.-as the feeding oi: the web around the; platen is made more easily to the line-feeding mechanism'g Moreover, the web is still gripped by the platen and its feedrolls, and also-by thei that is connected to the carriage, saidlfram'e being at therearvof the carriage so thatthe gripper rolls face theweb rolls and are" substantially parallel therewith, and I t he frame ishadapted" to roll upon' aft'rackpio vi' de d therefor. Other'features and adt-"a pear hereinafter. I s

In the accompanying dra wings, ';F igure is a front perspective ele a'tion'Sofa-typewriting "machine showing theangular" 511' rangement of spools therewith to" supply; Webs to the platen, gripping means for the} "t e f WtilIe E webs, and angular-directing means therefoi 3-with the line-space wheel 1 and finger piece '5, the line-space wheel as usual being actuatedby a line-space lever 6 operating pawl 7. The carriage is provided with a paper table 8 of the usual character.

The typewriter frame may be provided with an auxiliary frame or base, as9, which may be rectangular in form and extends out at one side of frame 1 and to the rear thereof.

Placed at one side of the machine frame 1 and for convenience mounted upon the base 9'is' a spool or roll support which may comprise the standards 10, spaced apart and adapted for rotatably mounting therein one or more spools or rolls 11. Vhen a number of rolls 11 are employed, they are mounted one above another as shown, and an assembling bar, as 12. is supported in advance of the upper roll to support the web from that 'upper roll and from such lower roll or rolls as may be employed, the assembled "webs extending from said assembling bar to the typewriting machine at the rear of the carnage 1n parallelism with the platen.

The carriage" has a rearward frame extension 13 with a support 13*, adapted as by means of rollers 1-1 to travel upon a track or rail 15 at the rear of the machine frame 1, which rail may form the rear bar of the base frame 9; said frame extension 13 carrying gripper rolls as 16, 17 which may be opposite the assembling bar 12 to receive between them the web or webs therefrom, said web or webs at the opposite sideof the

gripper rolls

16, 17 passing around a turning bar or roll 18 which is mounted in bearings 19 in frame extension 13 in diagonal relation to both the platcn'3 and

gripper rolls

16, 17, said web or webs after leaving the bar or roll 18 passing forwardly over the paper table 8 to the introductory side of the platen. A bar or roll 20 may be pro vided to receive the web or 'webs' from the oblique bar 18 in their path to the platen, said bar orr'dll 20 being located for the purpose in parallelism with the platen and supported as by bearings 21 in thevicmity of the paper table.

Under the arrangement of web-supporting and guiding means indicated, the web or webs in their passage from the roll or rolls to the platen are folded once diagonally, the web or webs being supported at that fold and their angle of direction changed to'cause them to pass thence in a direction at right-angles to their former d1- rection and forward to and around the platen.

Th sthe carriage with the gripper rolls and oblique or diagonal angle-changing bar or. roll comprises a unit Whose movement to the right, as in the carriage return for startmg a new lme of writing, thereby draws a quota of web material from the roll or rolls in extent equal to the distance traveled by the carr age to the right. Each letter-space movement of the carriage to the left slackens the web 1 or webs accordingly, between the rolls. 16,- 1'7 and the spools, but does not create; any slackness of the web material between the gripper rolls and the diagonal bar 18 or between said diagonal bar and the platen, because the gripper rolls exercise pressure upon the web or webs between roll or rolls is drawn upon and feeds between the gripper rolls to satisfy the linespacing requirement.

The

gripper rolls

16, 17 are adapted to be separated as for purposes of introducing a web or webs therebetween, the separating means here shown comprising movable bearmg members 22 for the upper rollsl'l, with springs 23 normally holding said bearing members in a lowered position with the rolls 17 pressing against the roll 16 and a cam 2 1 with finger-piece 25 to elevate the .bearings 22 and thus separate said gripper rolls.

The bar 18 which serves to direct the webs, changing their parallel movement withthe platen to direct movement toward the platen, may, as stated, be in the form of a roller, and is shown as journaled in bearings 19, being adjustable by means of said bearings in order to regulate the angle at which said bar is set relatively to the platen. The means of adjustment here shown consist of slots 26 formed in abar 27 which connects the bearings 19, the bar 27 being shown as comprising a strip lying horizontally beneath the bar 13 with its ends turned up to form-the bearings 19, said bar 27 being supported by brackets 28 mounted respectively upon the carriage frame 1 and the extension frame 13, screws 29 placed in said brackets 28 engaging the slots 26 and permitting the adjustment aforesaid.

. The. bar 18 is shown as inclined upwardly to a slight extent toward its forward end. thereby providing an uphill surface for the web or webs passed over said bar to counteract any tendcnov of said web or webs. while being drawn around the platen, froin slipping edgcwisc along said bar. It will be appreciated that even though a web be taut. and under tension at opposite ends, yet when drawn over the oblique or diagonal bar, the planeof the moving web being even further corrected through theslight eleva 'tion of the bar'18 in thefdirection of that triangular apex, as is-evident, and thereby the web or webs are caused to'feed'accu rately to the' platen, intheir passage pass- 5 ing over the guide bar 20, which for the purpose represents the forward gripping device in the relative arrangement with the diag, onal directing bar 18, because from said guide bar the web or webs feed to the platen.

Spring fingers 30, or other usual means, may bear upon the rolls or spools to restrain directly e the webs from unwinding excepting as and when drawn therefrom 1n the operation of the machine.

Variations may be resorted to within the scope .Ofthe invention, and portions of the improvements may be used without others.
