TYPE-WRITING MACHINE. A

T all whom it may concern:

Be' it known that I, Jessa A. B. S1vr1rn, a citizen of the United States, residing in Glenbrook, in the county of Fail-field and State of Connecticut, have invented certain new and useful Improvements in Type- Writin Machines, of which the followingis a speci cation.

My 'nvention relates to ty ewriting machines, and is herein-disclose as applied to an Underwood typewriting machine, having a fan-fold attaclunentsuch as is disclosed in thepatent to Wernery & Smith, 1,132,055. heat or web of paper,-which is folded length ise one or several times, is fed from the rear of the machine around beneath the typewriter platep, and up. in front past aknife which lsadapted to tear off sections of the sheet or Web at 'a suitable distance above the printing line.

In said fan-fold machines,"therelation ship of parts is usually such'a's to enable as greats. part as possible of the work of hanling the sheets to be done a practically One of a stop or 'gage against which the typist may mechanically adjust the fanrfeld sheets so that they may be torn off at the proper "point. Indoing this, the platen is usually swung up clear of the'usual feed roll, and

until the leading edge thereofstrikes said mgage. The typlst then throws the platen work-sheets agalnst the feed roll, and thensame, size, and this sometimes renders the bookkeeping system unnecessarily bulky or easily the paper table is pulled over toward the.

typi'st, who pulls the work-sheets forward back to normalposition, where. it' holds the tears oi? the advanced sheets by the knife which hes along the end of the form printed on the sheet. Then the platen may be caused to advance the work-sheet.

Since the fan-fold web is an integral sheet, fall the forms thereon? must bemf the deranged, owi to the fact that the "separated forms arch elyto be misplaced.

Moreover, all the sheetsof the fan-fold web are of the same color, to avoid prohibitive cost, and it is desirable to have some record of a kind of paper which is distinct Specification ofLetters Patent.

rate or'distinctive recordsheet is usua Patented Oct. 8, 1918.

Application filed February 5, 1917. Serial Ito. 146,557..

in color frdm the fan-fold record. A-sep separately from the fan-fold web. This separate sheet may have the typed carbon copies of a succession of the forms of'which the fixn-fold web is made up; and may serve the purpose of a record or condensed-record copy. I provide means whereby a special'reeord sheet-may be fed throu h the machine to- .gether with the fan-fol web, and between the latter and thelplat'en, and may be also separately held and retained in a stationary condition while the fan-fold web is being advanced for the purpose of bringing a new sectionof said sheet. into writing pos1tion.'.

To enable this record sheet't'o clear the r-ga'ge, which serves to positionthe fan-fold web for cutting, said record sheet, as it ad-. vances from the platen, may-be carried behind'the usual paper'table. Lhaw provided said table witha slot or. opening which may direct said-record sheet away from the fanfold web. This separationis facilitated bo- .;caus e.the record sheet is usually of comparatively thin paper, and lies against the pa or table, while the fan-fold sheets form a rat er stifi web, and scfail to enter said slot.

In order to; al lne the record sheet when first inserted, the paper table may be pro"-- vided with alining devices; and said table may also be slotted, or perforatedo'pposite. or adjacent said devices to enable the typist to see that therecord sheet is" in proper po-Q,

sition when said table is in inverted p sition, a'twhich time the paper table. a

The alinin devices may be in the form of fingers or ro s, and they, may also serve to i I clip and hold said record sheet temporarily stationary when the-platen is, lifted up). the web, is being' pulled forward to a form into printing position-u Said; sheet maybeg il 'fQl-fi fi'ld gers or rolls. 'Thet rolls or clips matically becomp wp fieetipe record sheet'lies under the and being done on the work-sheet, that is to say, when the platen is returned to printing position. Certain featuresof the invention are useful for controlling separate sheets in other positions than between. the remaining work-sheets and the platen.

Other features and advantages will hereinafter appear.

In the Underwood fan-fold typewriting machine,- the typewriter carriage 1 travels on a rear rail 2 being fed forward in the usual manner at every stroke of a type-bar 3. Fast to the typewriter carriage and travs cling therewith is a rcarwardly-extending frame 4, which includes a supporting roll a running on a rail 5. Said frame includes parallel rails 5 and 6 for a carbon sheetcarrier 7, and also includes a. rearcross-bar '8, over which the fan fold sheets or web and the record sheet may be pulled to be advanced forwardly under a platen 9. In

order topermitthe sheets to be-pulled forward easily in this manner and to enable the carbon sheets to be advanced with them,

and the latter to be pulled back independ' pently-thereof, the platen 9 is journaled in .;,:t.le- ,sual fan foldswing frame 10, which is pivoted on a front bar 11 of the usual typewriter carriage 1. latched down'by means of a pair of hooks l2,

I pins 13 on said frame, said hooks being .writer carriage. i In order to release the swing frame 10, the

'60: f in Fig. 3, to ineffective position, one of the Said frame is usually one at each side .of the machine, which engage fast on a rock shaft 14 journaled in the typeli ooks ,12 may be swung rearwardly, as seen hooks being prorided with an extension 15, ..,fO Illi1I1gjL fin gen-piece 'forso releasing'them.

I ,VVhen so released, 'the swingpg frame may be swung forward until the aper table 16 1,2so,sae

thereof is substantially in a horizontal position, as seen in Fig. 5. In this position, the fan-fold web 17 may be easily drawn forward under the platen, it bein alined by the usual side gages, not shown ierein. At the same time, a record sheet 18 may be threaded forward between the platen and the fan-fold web 17. In drawing forward the web, there are threaded between itsfolds two or more carbon sheets 19 and 20, according to the number of copies to be'made in the fan-fold web, and there is also threaded between the record-sheet and the fan-fold web a carbon sheet 21. These carbon sheets are caught in holders 22 in the manner usual in these fan-fold machines, said holders forming part of a light carriage '23, which travels on the rails 5 and 6, a'iid is adapted to seize the carbon sheets and to feed them forward and backward between the folds of the fan-fold sheet or web when it is in the horizontal position seen in Fig. 5, in which position there is so little friction between the carbon sheets and the folded web that the sheets may be easily pulled rearwardly by means of the carriage 23.

To enable the typist to operate the carriage 23 conveniently, it is rovided with a forwardly-extending han le 24. In threading the fan fold sheet and the record sheet beneath the platen in the manner described, it is frequently customary merely to advance the web sheets and carbonsheets far enough to enable the feed rolls to grip them when the platen is swung back to normal writing a position (see Fig. 2). If it be desired to accurately posititon the record sheet at this time, the record sheet may be advanced until it strikes a pair of gages 25, of which there is one at each side of the paper table 16, which I gages may be in the form of rolls.- The carbon sheets may be similarly positioned by allowing them to be drawn forward with their carriage 23 until said carriage strikes a stop, such as the cross-bar 26, which arrests them in the right position. U

The paper table may include side gages for the sidewise positioning of the .record sheet. In order to enable the. typist to. see that the record sheet is accurately positioned and not accidentally caught against a'wrong part, the paper table is provided with slots- 27 at each side thereof adjacent the g'ages25, and extending partly thereunder, through which the typlst may see the record sheet has neath the paper table 16 in its inverted position,'seen in Fig; 5.

In the ordinary working of the fan-fold machines, thefan-fold web is, as mentioned neath the platen when the platen is in its up above, usually advanced to the point atwhich s per position. The carbon sheets are in the" in which position it is held by the hooks 12,

which are-cammed rearwardly as the swing frame approachesthe writing position, be-

cause the pins 13, which are provided with follower'rollers 30, strike the front cam faces 31 of the books 12.

Assoon as the swing frame is fully seated in writing position, the hooks 12 are swung forward to efi ective osition by the spring 32. This swinging orward' of the hooks causes them to remove the rolls or clips 25 to r the ineffective position, seen. in Fig.2; To effect this,'there is provided on one of the hooks 12 a follower pin 33, which is adapted to lift the rolls 25'by riding over arealvyardly-extendin'g arm 34 fast on the shaft 35, said shaft havin also'fast thereon arms 36 on which the r01 s" 25 are mounted... The 25- rolls-25 are thrown to eflective. position just as soonas the handle is moved rearwardly, because this carries the follower '18 and .thecarbonsheets meow-e21, the deflector plate 38} havin beenfihibwnback pg its-handle 39 to gui e thesh ets around e {The sheet then f plat n (see Fig.-"=f4).

may bewritten onandfilled inin the usual 7 manner. The advaneing of the recordsheet "18, by the line-space operation, :causes it p "to catch under and pass behind the turnedup, lip 39, forming part of the upper end of sheet through the opening and; behind said pa t bl while the-1am 9 Web 17 is too bu ky and too gtifljj @Fch r Me t t l p 39, Pa s er; 21

This indicates to the typist; that that sheet is in position for being torn off. The typist is enabled to y measure in this way by the gage, because the record sheet has beencarried out of the way of the gage by the lip 39, mentioned above. The typist now swings 'theswing frame loflbackto Writin position, Fig. 4, and tears off the fan-fol web b the knife 43, which is formed on the edge of the plate 38. This sequence of o erations makesthe typewritten items on,,t"e record sheet follow each other closely, althou h they may be widely spacedon the ran-015 webs TlllS follows from the fact that the record sheet does not move when the fan-fold sheet is pulled forwardly with the platen in its elevated position. Thus, the invention ma be utilize for'condensed billing, where the ills areon the fan-fold sheet. I

The typist then is ready to fillin a new form and may advance the platen by means of the line-spacehandle 38 to-bring the pro er line of the form to the printing point.

or somefpurposes', it may be desired-to able sheets f any desired size suitablefor putting in; ooks, andithe sheets may, there-- fore, be in the form of a'rolled web '44,. ro-

in the" post of the binders of the books. These openings. maybe brought to proper position relatively to thelinesof writing on the sheetsof the roll 44 by alining the end sheet against the gages 25.

The slot-3r9 is conveniently of exactly the width of therecord sheet intended to be used in the machine, sothat the ends 47 efthe slot 39 form convenient side gages for the record sheet'18; Thijsrecord. sheet is ad- ,vantageously wider than the. width of the folded fan-fold web, so that althoughthe '-,rollers 25 engage the record -sheet,.they are always clear 0 V V tney'lie outside of the edges thereo the fan-fold web, b s?
