Specification of Letters Patent.

- Patented Dec. 24,1918.

Original application filed April 28, 1917, Serial No. 165,055. Divided and this application filed July 1, 1918.

Serial No. 242,734.

To all whom it may concern:

Be it known that-I, JESSE 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 Typemachines disclosed in said patent are capa b le or" writing upon what is known as a fan-fold web, which is so folded as to make several thicknesses of work-sheets which afterward can be separated.

Such a fan-fold web has the great advantage that headings, etc., printed thereon, are positively held in alinement with each other upon the several plies even. when teeding around the platen, because. each web or ply isbound to the two adjacent. webs by the integral edges at the fold, and these prevent either ply of the tau-fold sheetfrom feeding faster than theothers.

' Theprescnt invention is a division of my application, Serial No. 165,055, filed April 2S, 1917, and includes devices which are adapted to retain many of the advantages of said patent, and at thesame time enable separate webs or plies to be used with facility. thuspcrmitting one web to be of one I color or quality of paper, while the other webmay be of different qualities or colors.

In the form or the invention herein disclosed, the carriage of the typewriter is in many respects like that in the patent referred to, and includes a carbon paper car- I'iage which is adapted to be moved for, wardly and backwardly along the usual typewriter carriage. The webs of paper,

I owing to their weight, are usually mounted upon stationary supports, so that the typewriter carriage is relieved of the strain of driving them. The rolls, which deliver the webs to the typewriter carriagc, are, accord ing to the present improvements, placed so that before reaching the typewriter carriage, the webs are free of tension or are unsupported for quite adistance, thus allowing the typewriter carriage to travel almost unimpeded by the webs, because the space over which the webs are free of tension enables the webs to twist freely and idly in that space. Instead of being actually unsupported, the webs may lie for a part or all of the distance upon a flat table, which permits them to slide or swerve sidewise at will.

Owing to the fact that the paper forming the webs has some thickness, and that this thickness at the platen is materially increased by interleaved carbon papers, the outside web normally would tend to travel considerably faster around the platen than the inside web, with the result that if the forms printed on the different webs register when the leading edges of the webs are first inserted into. the typewriter, they very soon cease to register because'the outside web travels faster than the inside Web.

The invention may also include a connection to the carbon paper carriage, such that. when pushed rearwardly, the carriage will unwind practically the full length of a form from the webs. so that the subsequent linespacing operation in fillingout the forms, will not throw upon the line-spa e lever the load of unwindingthe webs. Thisalsohas the advantage of producing some slack in the webs which serves to diminish the side twisting of the webs which ensues from the "travel oi the typewriter carriage.

Other features and advantages will hereinatter appear.

In the accompanying drawings,

Fig. 2 is a sectional side view of the same, with the parts set for beginning to fill out a fresh form.

Fig.3 is a sectional side'view, showing the webs stretched out straight, and the carbon paper carriage clamp released, just at the moment of starting to push the carbd'n paper rearwardly, preparatory to bringing a new form to the printing point. 7

Fig. 4. is a view similar to Fig. 3, but

shows the carbon paper carriage clarnprean adjustable outer end gage 18.

types 1 at the strike against the front side of a rotatable platen am a carriage r. The platen 3 is rotated by means'of a knob 5, mounted on a stub axle-6; o'iby the line-space lever 7, which is adapted to drive rearwardly a slide 8 etiectir on the line-space detent wheel 9'. The platen is mounted in a swing frame 10, which is journaled on a front axle-11, in such away that as the swim frame-l is thrown upwardly and forwarc ly, the platen swings therewith, but is constantly kept engaged with the line-space mechanism be-' cause a pinion 12 fast to the end of the platen axle, remains in mesh with a pinion 13 faston the shaft 11, and the pinion 13 is also in mesh with a pinion 14 fast to the stub axle 6. When the swing frame is swung up. the platen occupies the position seen in Fig. 3, in which position webs 15, 16 and 17 I may be drawn practically straight from the rear of the machine under the platen to have their leading ends gaged by After being thus drawn forward and gaged, the webs are usually cut off. Thisis done after the platen ,llis swung back to its normal position, there being provided for this purpose a knife 19, adjacent the front of the machine. The usual front and rear feed rolls 20 and 21 hold the webs 15, 16 and 17 against the platen, during the severing operation, while the platen is latched in its downward normal position bytheusual latch 22, which is-swung forward by a spring 23,510 that it catches over a pin 24 on the handle 25, which is provided for swinging the swing frame .10 upward and forward.

As the webs 15, 16 and 17 are fed forward for the purpose of writing on them, they draw with them. interleaved carbon sheets 26' and 27, which are clipped to the usual cross-bars 28 projecting fromthe op: posite sides of a carbon carriage 29, common in this type of machine. carriage 29 runs on rolls-"30, which rollon rails 31 fast to thetypewriter carriage,said

rails bcingIuni ted' by a cross-bar 32at their rear ends, thus forming a frame which includes a wheel 33, traveling on' a rear rail ift. Atgi'th'ei front end the rails are fast to brackets 35 on the typewriter carriage ada cen gthe usual rear carriage rail 36. When the webs 15, 16 and 17 are stretched out flat wardly by handle 37, hon paper- sheets 26 and 27 back to thepositic-n seen in Fig. 4, in which position. the carbon'paper sheets are clear of the knife 19,

th the result that the carbon paper sheets remain intact while the webs are being later warn oil. I i

The carbon paper the typewriter usually pushed rear-- so as to shift the car;

at 58, so that.

Tn order to properlyaline the webs. there are provided on. the swing frame 10 adustable edgegages 38, formed as the; turnedup edges of plates 39, which lie on the table.

40. Besides the edge gages 38, there are also provided edge gages' ll adjustably mounted on the carbon paper carriage 29, these latter edge gages serving to guide the webs straight as they approach the platen 3.

The webs as herein shown are drawn from three spools 12, i3 and 44:,wl1ich are jonrnaled on spindles in a suitable'fixcd frame 45. beneath the typewriting machine and may be conveniently placed near the floor, under whatevcrtable the typewriting machine is mounted on for the time being. From the spoolsi12, 13 and 44. the webs guides 16 from which they extend in a straight clear reach to a second set of guides 47. The reach froni 16 to at? may be equal to or greater than the travel of the carbon papercarriage 29, for reasons which will presently appear.

From the guides 47, the webs rise and turn forwardly over the rod or bar which,

As herein illustrated, these spo ls are are led past r therefore. may, if desired, be several feet i'ertically from the guide 47, thus making any twisting of the webs, between 47 and'32 is such a clamp 72 near each margin of the webs 15, 16 and 17. To operate these clamps together, they-are mounted on a transverse shaft. 78, which is provided with a rock arm 79 having a pin 80 working in. a cam slot 81 in aplate 82. This plate is preferably connected to be operated by a fing( n'-piece 57 by means bf. a horizontal link 83 extending a from a lowerextension 84 of said linger' piece, said link 83 operating a rock arm 85 fast to the end of the shaft 86 at one side of carriage. 'This}. rock arm operates the cam plate 82 by means of the rock shaft 86, said rock shaft having also -fast thereto a second rock arm 87, which is joined by a link 88 toa rock arm 89 splinedf" to a shaft 90. adjacent the shaft 94. The shaft 90 is journale'd on brackets 91 forming partof the'carriage 73, andoperates the cam plate 82-by means of arms 92'and 93.011 the shafts 90 and 94, respectively, said arms be .ing joined bya link 95.

It will be seenthat the finger-piece 57 is adjacent the handle-37 andpivoted' thereonjusting the carbon paper by the handle 37, is

the'handof thetypist, in adenabled to readily adjust the finger-piece by motionof the handle at the same time.

The carriage 7 3 has been described as run ning on fixed rails 75, while the carbon paper carriage 29 runs on the rails 31, which form part of the typewriter carriage. In order to enable the link 88, which connects the fingerpiece and clamp 72, to remain vertical despite the feeding of the typewriter carriage sidewise past the lower carriage 73, the splined arm 89 is slid along its shaft 90 by means of a stiff vertical bar 96 project- -ing-downward from the carbon paper carriage and having at its lower end a fork 97 which embraces the rock arm 89, thus cans mg said rock arm to slide along its shaft with the travel of the typewriter carriage.

hen the carbon paper carriage is pushed back, the clamp 72 will be seizing the lower reaches of thewebs 15, 16 and 17 between the supports 46 and 47, thus unwinding each web 15. 16 and 17 from its spools 42, 4:3 and 44 an amount precisely equal to the amount that the carbon carriage is pushed back ward. This produces a bight 98 in the webs between the support 47 and the rod 32.

When the carbon paper carriage is pushed all the way back, the stop 69 causes the 1 During such forward*"movement of the carlion carriage",the bight or. slack at 98 is partly or wholly taken up, such bight being replaced by the next rearward travel of the lower carriage 78. v

When the'platen is in the Fig. 3 position, the clamps 7 2 will seize, if the typist pushes back the-carbon paper carriage at this time, with" the finger-piece 57 in the Fig. 3 position. Thus a bight 98 is formed every time the carbon paper carriage 29 is pushed rearwardly, and this bight is gradually taken up by the line-spacing or other feeding of the webs around the platen. It will he usually found advantageous to adjust the webs at the beginning in such a way that there is an initial extra 'bight between. g and 32, this bight, of course, being much greater when the carbon paper carriageoarries the lower carriage 73 rearwardly than it is at other times. When the finger-piece 57 is pulled forward to the Fig. 3 position, a bell-crank 62 may be actuated by means of a link 59 extending from said finger-piece 57 to swing an arm 66 of said bell-orankfand permit a latch 34 to be drawn by a spring 65 under the arm 66 of said bell-crank, thus latching the. finger-- piece in its forward position and therefore holding the clamp 72' locked in its effective position.

The clamp 72 may be released at the end of the rearward movement of the carbon carriage 29. This may be done by a tail'67' of the latch til, projecting downwardly'below a pivot 68 thereof, which strikes against a. stop 69 secured on the left-hand ,rail .31, thus causing the latch 64; to free itself from the bell-crank 62, thereby permitting 'a spring 70, coiled around the shaft 71, to rock said shaft, and, by means of the mechanisms connecting said shaft with the clamp 72, cause said clamp to become ineffective. The stop 69 which arreststhecarbon paper carriage 29 may be adjustable, and fastened at anypoint of the rail 31 tosuit the work in hand; F or this purpose, it is held to said rail by a thumb-screw 71.

There may be provided a table 99, which extends rearwardly from the support 47, and is preferably either entirely without sides, except immediately adjacent to support 47, or has such low sides that the bight 98 can slip over the sidesof the table... The table may be formed from two plates of sheetmetal, each slidable on, and embracin a lower rod 100, and having a sleeve 1C1 s iding on an upper rod 102, the rods 100 and 102 forming the support 47. 'The rear end of the. plates forming the table 99 may be bent downward, as seen in' 3, so that when the web is drawn re'arwardly by the clamp 72, it will form a bight, slack or supply, which at first will lie on the table 99, but which will be gradually taken up in the linespacin operation during the typewriting or filling in of the various blanks on the web work-sheet. The plates forming the table 99 may have their edges turned up at 103 to slip sidewise or twist on the table 99.

In order to keep the weight of the'webs' 15, '16 and 17,-betweenlthe supports 46 and 47, from drawilna, the jbight the table 99, thereby all )wing the webs to'sag' the edge guides formed thereby are err- .trenrely short, thus allowing the webs to of the weboii' down between said supports as and 4:7,jth6' jaws 77' of each clamp 72 may be elevated above the plate 104 which formsthe top of the carriage 73, and the jaws 77 may becut oil? at the sidesof the clamps 72 near thecenter, to make room fora fixed plate 105 lyllli between the jaws 77 and extendingbeneat the webs i5, 16 and 17 to support them throughout their length between the supports .46 ,and 47. The plate 105 forms a table having an-=extension 106, which'embraces the rod 100, and a seco'nd extension which embraces a rod 107 forming the lower iso ' 'elamp "2.

row web is used temporarily.

pose, the webs are shown herein as provided rod of the support-46. Thus it will be seen that the webs 15 16 and 17 are supported horizontally throughout their length from the support 46 to the support -17; except at their margins which extend beyond the plate 105. and therefore -n be gripped by the The webs do not sag between the rails 31 because the usual supportin rods shown in the patent to Jesse A. B. gmith, No. 1,177,546. not seen herein, support the web where it does not rest on the carriage "29.

()n theniachinef herein shown, the'spools 4'2. 43 and it arepositioiied vertical-1y below the center of the t v'pe \\"i'itiii,r r niaehine and consequently below the renter of the travel of the t. \'pe\i'riter' carriage. NVith the rolls in this position on the machine,' the typisi Hl:\ draw the webs 15, ,16 and 17 straightonto the platen without any twisting whatsoever i f the typewriter carriage is positioned at tlie eentei" of its. travel. The typist. however, will often draw on the webs with the typewriter carriage positioned else where than the center. thus tending possibly.

to some. eXtent'to twisttlie webs. In order to positively aliiie the webs at will, both as to twisting and to cause the forms printed on d li'erent webs to register with each other,

nieans uiay be provided whereby the typist ran aeeurately reregister the webs at treouent intervals, independently of any other devices. thus avoidingthe neeessity of re-adjusting the other devices, espeeially it' a nar- For this purl with pertointions at identically eorresponrb lug points; 10h, and the end gage 18 is provided with a tapered pin lone-t the same size as the perforations 108, so that thetypist can draw the webs out horizontally as shown 111.

Fig. 4, and aline and re-aline the corresponding printed forms on the various plies when ever required, this being accomplished by fitting'the perforations 108 over the pin 10%), as shown in Fig. 4, after which the platen may be thrown back to the normal Fig. 3 position; as described above. The form which has already been written on, and which is just below the perforations 108 may be torn ofl. In many cases, as where strongwebs are used, the typist may hold the webs hooked onto the pin 109, while the platen is being thrown back into its writing position, though with some webs which are easily torn it may be safer at times to merely fit the webs over the pm 109, and then allow them to spring otf while the finger of the typist holds the webs against the usual smooth bar 110, to which the end gage 18 is held by the usual thumb-screw 111. This bar 110 is usually grasped as a handle by the typist to throw the platen up and down,

thus forming a rest for the finger of the typist in holding it e webs on the pin 109.

Variations may e resorted to withinthe scope of the invention. and portions of the improvements may be used without others.
