To all wimmt may concern.'

Be it known that I, ARTHUR A. JOHNSON, a citizen of the United States, residing in Lyndhurst, in the county of Bergenand State of New Jersey, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification. Y I

This invention relates to .an improvement in typewriting machines, and more particu-A larly to a fan-fold attachment for making manifold copies 'continuously., using the same set of carbon sheets. -This case is an improvement on' my application, No. 17 6,488, led June 23, 1917, and on the patent .to "vii/'ernery and` Smith, No. 1,132,055, dated March 1 6, 1915. A

@ne of the objects of the invention is to providev improved means for enabling the same sheets of carbon to be used repeatedly with a number of successive sections of a fan-fold web, so that the sheet and carbon leaves will b e always assembled relatively to each other ina pack. As one portion of each carbon sheet is worn out, afresh. portion may be drawn on to replace it. Thisl avoids the necessity of frequently taking apart the assembled pack of interleaved carbon sheets and web.

For the purpose of facilitating the use of the continuous supply of carbon with the continuous fan-fold web, the plies of the web are threaded between a series of diagonal guides or warping bars, which direct the carbon sheets from the side into line with and between the layers of the fanfold web. The supply rolls from which the carbon sheets are drawn are mounted on the table carriage on which the bars or guides are mounted. This table carriage moves f orward with the advancing line-space rotation of the platen. Thus, thecarbon sheets and their source of supply -keep pace with the l movement of the web. The carbon sheets are Vmoved rearwardly relatively to. the worksheets, by pushing thetable-carrlage rearwardly. Tn doing this, the carbon sheets are y not ordinarily withdrawn from their rolls, as only that portion which is between the folds of the work-sheet web is used. Locking or clamping means is provided for premay be released when it-is necessary to re new the carbon sheets between the folds of the work-sheet web.

The platen is raised, as more particularly described in the above-mentioned patent, for straightening out the bend in the assembled work web and`- carbon sheets, to enable the relative displacement or spacing between the same.

Other features and advantages will hereinafter appear.

In the accompanying drawings, j

Figure 1 is a perspective view with the work-sheet web and carbon sheet removed to disclose the underlying structure.

Fig. 2 is a top plan view with the worksheet web broken away to show the underlying structure.

Fig. 3 is a vertical section, taken from right to left, looking at the machine from the front,and shows theclamps for the carbon sheets as in action preventing the with drawal of fresh carbon paper from the rolls.

Fig. 4 is a vertical'section, taken at right angles to Fig. 3.

Fig. 5 is a detail view, similar to Fig. 3, except that the clamps for the carbon sheets are released, to enable the fresh supply of carbon sheets to be drawn from the roils.

showing how the carbon sheets are interleaved between the folds of the work-sheet web.

is pivotally mounted by means of a swinging frame 3 on the platen frame 4. The platen frame 4 is mounted on a carriage 5, which A platen 1 is supported by an axle 2, which platen axle 2, but not rigidly connected therev to. To connect the platen axle 2 with the knobV axle9, there is provided on the platen axle a gear 10 meshing with a broad pinion 11, which, in turn, meshes with a gear 12 'of the knob. axle 9, of substantially the same. gear l0. In this way, the' diameter as the rotation ofthe knob 7 and the movement of the line-space lever 8 are indirectly transmitted to the platen 1. This arrangement enables the platen 1 tobe raised from its locked in a typewriting position lby a spring latch' 14.

'carbon sheets may be straightened out, so

that the carbon sheets can be readily slipped along the work sheets for spacing purposes. To raise the platen in' this way, there is provided a handle 13, which is normally The work-sheet orweb, indicated at'15, is in the present case of fan-fold type, and is shown to consist of ve layers or folds which are connected in a continuous series at their side edges. This fan-fold web, as a whole, is in a continuous strip which may or may not have printed forms thereon to lbe torn off successively as typewritten to form separate bills or letters. The web 15, in order to have the matter typewritten on 'the exposed layers take on the under layers to form duplicate copies, must be interleaved with carbon sheets 16. There are four of these tar-Y bon sheets shown, one for each of the under layers of the fan-fold web. To `direct the carbon sheets 16 from a source of supply off to one side to a position between the layers or folds of the web 15, there are provided a work-sheet web and the carbon sheets in' a line-space direction, so as to keep pace with the rotation of the platen. .The table 19 also keeps pace with the letter-space movements of the platen l by. being mounted on an extension 20 carried by the typewriter Acarriage 5. This extension is supported by a roll 21 running on a rail 22, provided on a bracket 23, extending rearwardly '.rom the typewriter frame. The mounting of the traveling table 19 may be of any suitable character, as by means of wheels 24, traveling in rails 25 provided by the extension 20. Although the carbon sheets may-be. used repeatdly with a number of successive sections oie the work-sheet web, in the' course of time the vorn out.

rolls 26 are arranged parallel to the direction of travel of the table 19, so that the car bon sheets extend from theserolls to the guides 17, and then are warped to extend inA the direction of travel of the'table 19 and also in theV direction ofthe travel of the web 15.v The rolls are arranged two on each side, the outer ones being slightly 4depressed below the inner ones, as illustrated in Fig. 3, s o as to enable the lower carbon sheets to clear Ythe inner rolls. The rolls 26 may be detachably mounted in bearings 27, so that when all the carbonpaper on them is used up, they can be replaced by fresh rolls. For this purpose, the bearings 27 are open bearingsclosed by springs 28,- which engage the axles of the rolls 26.

In order that the carbon paper may not be drawn from the rolls 26 until it is desired to renew that portion of the carbon sheets which is'between the folds of the web, there are provided paper locks. or clamps -29 and 30, one for each pair of canbon rolls 26. These -clamps each comprise a stationary jaw 31 and a pivoted jaw 32. Normally, the pivoted jaws 32 are'held in the position of Fig. 3 gripping :the carbon-sheet strips between them. Y This is done by providing each of the swinging jaws with a pin 33. These pins extend into cam slots 34 provided in levers 35 and 36. The levers 35 and 36 are connected by a link 37, so as to move in unison, 'thereby' closing o r opening thev clamps 29 and 30 in unison.

.is provided with a grip 38, whereby the lev- The lever 35 ers 3'5 and 36 maybe manipulated to open and close the clamps 29 and 30. The cam slots 34 are 'formed with end dwells (see 3 and 5) so that they will automatically swing the pivoted jaws 32 according to the direction of movement of the levers 35 and 36, and the dwells will lock, them in their open or closed position.` 1n this way, the'supplyof carbon paper is not drawn on until needed, although the movement of the work-sheet web relative to the carbon sheets would tend to draw the carbon paper from the roll.' Y

Y The utility of the devicev will be readily understood when taken in connection with the above description, Starting 'with the .assembled pack of work-sheet web and carbon sheets, in position on the platen to be written on, the bill or other piece of work is typewritten line -by line. The web and carbon sheets will advance line by line with the line-space movements of the platen. The web and carbon sheets will draw the" traveling table 19 along with them, and there will be no appreciable relative movement between the table and either the web or carbon sheets, the latter being locked by the clamps 29 and 30.

lFehen a bill l0r other piece of work is completed, the platen 1 is raised by means of the handle 1.3, yso as to straighten out the bend 1n the assembled pack of paper. The

table 19 can then be forced rearwardly by 4portion of the work-sheetl-Web. This may be determined in `any suitable mannen as by bringing the leading edge ofLthe worksheet Web into engagement with an adjust- The platen l'canthen be returned to its typewrlting position and rotated .either by the knob 7 orthe line-space lever 8, to bring the initial line to be Written on in register with the printing point of the typewriter. This will carry the table 19, the web 15 and the carbon sheets 16S-.along in I unison. When the bottom edgeof the completed piece of work-has come in register with' a knife 41, the piece of work may be severed from the continuous strip of web. The new piece of Workfcan be written line by line as before, and, when completed, a relative spacing between the carbon sheets and the work-sheet web may be made and the operation repeated over and over again, thus obtalmng dupllcate copies of a number of successive pieces of work, such as bills, in a continuous manner.

When the carbon sheets between the folds `Action agam, soas to prevent more carbon paper than isneeded from being unrolled. The used portion of the carbon sheet which is to be discarded wi1l be cut off by' the knife 41, when the partlcular bill or letter with which it is lnregister is-severed the body of the web.
