TYPEWRIIING MACHINE.

Application filed July 10, 1924. Serial No. 725,129.

This invention relates to manifolding upon fan-fold paper work-webs in typewriting machines, particularly those having revoluble platens. I

The usual practice in such-types of machines is to locate individual sheets of carbon between the plies or folds of the web in a manner which calls for straightening out the web at frequent intervals to permit the shifting of the carbon-sheets along the web from the typed portion thereofto the untyped portion of the same. An occasional incident to such shifting of the carbon-sheets has been the maladjustment of individual carbon-sheets relatively to others between the plies of said web. In orderto overcome the foregoing drawback of shifting the carbon-sheets, as is now found necessary in the present marketed Underwood fan-fold machine, 7 the present mechanism is provided, which is primarily designed to simplify construction in a manner that renders unnecessary the raising of the platen for-the straightening of the web, or shifting the same to release the carbon-sheets from contact with the plies of the web. I

Another object of the invention is to provide means for automatically or manually measuring predetermined uniform lengths of the web as the same, after being printed, is progressively carried beyond the platen in order to assure that these predetermined typed portions of the web may correspond to the length of the printed forms on the web prior to severing them from the'untyped portions thereof.

A still further object of the invention is to provide various economies in the construction and operation of signed to produce simultaneously typed impressions upon the several plies ofa fanfold web, looking towards the ultimate separation of each member of a series of for-ms. printed consecutively upon said web.

It is a still further object of the invention to attain the above named results by the aid of inlr i-ibbons instead" of carbon-sheets as the manifolding medium gfor' producing 81- mulwnewsly typ d mp i ns upon" the separate jplies of a fan-fold a mechanism depressions upon all the pliesof a RSEY, ASSIGNOR TO UNDERWGOD TYPE- Other features and advantages will hereinafter appear.

Referring to the drawings, 10 designates the manifolding sheets or strips which are employed in the form oftypewriter ribbons,

which ribbons are auxiliary a main ribbon found in a typewriter. stretches of, ink-ribbon are arranged to positioned longitudinally of the machirreflsq as to be disposed at the'delivery side o platen along the printing l ne.

to the usual These It is (Olly templated' to use as many stretches of ribbon as may be necessary to produce typed web. The ribbon-Qarriers im: t n-f d are b eede de ignated l1, and each QilSiStS Q? a l ltg llli dinally extending co-extensively w th the e the whwh serves to position and support by n ns integral Hooks 1-3 fer-madapes 1*?5' QPP a mi bla 2 ex ending .mounted upon bracket-pieces ends, these hooks receiving the loops 15 formed terminally upon the ribbon 10, which ribbon is held against downward displacement from the blades by means of the bills 1 1- of the hooks. It will be seen that the ribbons are thus removably mounted upon their carriers.

A fan-fold web 1O is preferably employed in the typewriting machine upon which the attachment and invention is mounted, and this web is integrally provided transversely thereof, continuously of its entire length, with alternate folds E and F, providing a series of longitudinal plies designated A, B, O, D, and so forth, said folds being open at alternately opposite ends thereof for the insertion thereinto of the carbon ribbons 10, which ribbons may easily and removably be introduced, one entering from one side of the web and the other from the other side thereof, and so on, so that one loop end of each ribbon 10 will project beyond and out-- side the folds of the web, the other being encased in one of the folds of the web, as shown clearly in Fi 'ures 4t and 5. This results in the free ends of the ribbons and the hooks 13 0f the ribbon-carriers being supported in staggered relation with respect to the longitudinal edges of the fan-fold web 10*; however, the ink-ribbons 10, which are arranged in longitudinal alignment within the folds of the web-extend throughout the effective transverse area of the web, these ribbons acting as a unit for the purpose of receiving simultaneous strokes from the type-bars 35 of the machine.

16 designates the brackets upon which the ribbon-carriers 11 are detachably secured. 17 designates the platen mounted on a shaft 18 in the usual bearings of the machine, having a hand-wheel 19 for revolving the same manually, and. also carrying the line-space ratchet-wheel 47. Ears 20 extend preferably integrally and upwardly from the hooked ends of the ribboncarriers 11, so as to extend laterally outwardly thereof, and are removably secured upon the brackets 16 by binding screws 21, which are provided with the usual. nuts. The brackets 16 are 22, which are operatively positioned adjacent the platenshaft 18 at the opposite sides of the machine, and which bracket-pieces are secured to each other by a cross-bar 22. The left-hand one of the bracket-pieces 22 carries a pin 23 projecting preferably in a spiral groove 24 or cam surface formed upon a cam 25 carried by the platen-shaft 18, by means of which cam mechanism a horizontal movement is imparted to the ribbon-carriers 11 for a purpose to be hereinafter explained.

The bracket-pieces 22 carry headed studs 27 formed on the pins 23, which project into a diagonal slots 28 formed upon a slotted portion 28 formed upon the depending bear form designate the front and rear feed-rolls, which are retractibly engageable with the platen and serve to provide a tensioning means for holdlng the web in progressive feeding on gagement against the platen, so that the web may be carried along over the side of the platen in arched manner, as shown part-icu larly in Figures 1 and 2 at 31.

32 designates a slidable gage mounted upon a shelf-bar or gage-bar 1a which forms a restfor the advancing typed portion of the web j ust emerging from beyond the printing line of the machine. The gage is locked in adjusted position upon the shelf-bar by the usual thumb-screw 33, and the gage has an abutment or stop 34 for arresting the progress of the approaching end of a typed portion of the web at this point, so as to measure of and set apart a predetermined uniform length ofthis typed portion of the web. 35 designates the type-bars which operate in the conventional manner against the conven tional typewriter ribbon 38, which latter vibrates up and down in front of the platen at the type strokes, and with reference to which the ribbons 10 are auxiliary. The type-bars on impinging upon the main ribbon 38 also make impressions upon the ribbons 10, which shift relatively to the printing types in a manner which will be readily understood. In order to sever or detach each of a number of consecutive forms printed upon said fan-fold web 1O at uniintcrvals apart, is also employed, consisting of a tearing-off flnife 39 whch is located immediately above the ribbons and blades, so that the latter may remain in their positions between the folds of the untyped web. A knife-supporting arm 40 may be fixed in position, or the same may be pivotally supported so as to move from the dotted line inoperable position shown in Figure 2 to the full line operable position shown in the same figure. It will also be. noticed that the two ribbon-cara cutting means llO rying brackets 16 (one at each side of the shown in Figures 1 and 2, in order to hold tact with the platen. A stop pin 43 on the knife-supporting arm 40 rests upon a knife carrying arm 43 supported on the platenframe to cause the knife 39 to occupy its proper position at a point directly below the point where the gage 32 is fixed, so that the web, as it extends between the knife 39, when in operable position, and a point Where the gage 32 is located, represents the already typed portion of the form printed upon the web, enabling this portion to, be drawn forwardly against the knife so as to be severed therefrom. WVhen' the knife is not in use it may be swung out of the way, es pecially when the ribbon-carriers are being attached or detached from the machine. The cams 25 and cams 28 are responsible for prolonging the life of each of the lengths of ribbons, causing the type-bars to engage different, points vertically and horizontally of the ribbons. The cam mechanism also provides means. causing. the blades and ribbons to swing forwardly to. and fro in a direction universally of the platen, reducing eventually the paths of contact of the type-bars upon all of the ribbons designated M and N in Figures 8- and 9, which illustrate the fact that the major portion of the height of the V ribbon receives the repeated strokes of the type-bars, enabling the ribbons to be gradually used up. all over their area.

In operation the web 10 is lifted up and fed along down over the paper-table 36, passing between the front and rear feedrolls, and the web being thus progressively fed forward around the under side of the" platen 17. Thereupon the ink-ribbon blades 12' may be inserted in. alternate directions, as, shown in Figure 4, between the plies of the fan-fold web and secured to the platenframe by means of the brackets 16. The typing then takes. place and the web isfed past the ribbons line by line by the usual line-spacing mechanism, which mechanism also times the operation of the cam mechanism. When the typing of a form is com pleted, the advancing end of a web' may be manually drawn up to the gage 82 to measure'the length of the form, or the same will take place automatically if the web is properly arched; in any event,-whenthe free end of the web is stopped by the gage, this portion is thentorn off, after. engaging theqknife-bar 39-, so that the untyped; portions of the. web will remain snugly their positions behind andbetween the typewriter ribbons. which are properly nested and sandwiched between these plies. In this Way by rotating the platen, the plies of the web may be .m'oved through the spaces between the. ribbons 10,. and to severing. position, and

' by k epi g; the p at n mmova e, wWPI Q will remain stationary in these spaces so as to be engaged against the ribbons during the typing operation:

In some cases transparentor tissue paper 48, shown in Figure 5, may be used for the fan-fold web, so that two plies H and I may fall between the adjacent ribbon stretches .insteadof the usual single ply. The inkribbon causes a typed mpression in this instance to, appear upon both plies with which it contacts, and similarly the transparency of the paper will permit the typing to, be read after the forms are torn off;

At Figures 1 and 2, it will be seen that the ribbon-carrying arms 11 have their ribbon-attaching billsv or fingers 14 slightlycurved to conform to the curvature of the platen, so that they may readily be moved up and down, in the web-folds, in front of the platen. by'means of the ribbon-carry mg frame, which, it will be remembered, is pivoted on the platen-axle. It will further be seen that the arms 12 extend tangentially a short distance: away from the platen. If the knife: 39 occupied a permanently fixed position during the up-and-down swinging movement of the ribbon-shifting frame, the length of the web from the printing line to the edge of the knife would be increased and decreased slightly due to a bulge which would be-created in the web by the ribbon carrying arms 12- in their lowermost positions. To, avoid-such bulge in the web, or, in other words, to keep the distance from the printing line, to the edge of the knife always the same, the knife is supported upon knife-carrying arms 43', each knife-carrying arm being pivoted on a stud 50' secured to a downwardextension 51 of the bracketplate- The axes of the studs are in alignment with each other and in alignment with. the printing line, so that the knifecarrying arms 43' may be swung about the studstomove the knife toward or away from theplaten as the ribbons move up and down respectively, I It willbe understood that the bulge created in the web by the ribbon carrying arms when the ribbons are lowered isrtoo small to have any effecton the gaging of the sheet against the gage; 32. Consequently'the gage- 32- is supported on the gage-bar 44which' is relatively fixed. The cross-bar 22% which forms part of the ribbon-carrying frame,-

is bent back sulficiently so as not to obstruct the pat-h of the web. 31 when said ribboncarrying frame is in its. lowermost position, Figure 2. p a v From the foregoing it will beunderstood that there is provided means entending into.

a gage at the front of the platen to measure a stretch of work-web with reference to a knife, which web is fed between the auxil iary ribbons on the typewriter carriage, and that there are two supports on each ribboncarrier over which the ribbons may be sprung so as to be held taut between said supports to overcome any tendency of the ribbons to feed with the work-web.
