TYPEWRITING-MACHINE.

Specication of Letters Patent.

Patented Mar. 1, 1921.

Application filed June 20, 1919. Serial No. 305,497.

To all whom t may concer/a.'

Be it known that I, EDWARD THOMAS, a

citizen of the United States, residing in New York city, in the county of New York and State o' New York, have invented certain new and useful Improvements in Typewriting-Machines of which the following is a specification.

This invention relates to typewriting machines, and is herein illustrated as applied to the machines known as continuous ianfold billing machines, although such latter machines are not used exclusively for fanfold webs, or exclusively for billing.

In such fan-fold machines and in other machines, it would be frequently advantageous to be able to insert a work-sheet from the front of the machine around the platen passing it outside of a work-sheet or workf sheets, which may already be in the machine.

It has been found, however, difficult and almost impossible to insert short, separate,

work-sheets in this fashion, because there is great liability of their catching upon either the paper-apron or upon the feed-rolls or other parts beneath the platen. This liability of catching, added tothe -friction against the webs or work-sheets already in the machine, haspractically prohibited the general utilization of short work-sheets in these machines.

According to the present invention, the

platen of the typewriting machine maybe raised toa sheet-inserting position completely clear of the feed-rolls and other parts, and, while detained in such'raised position, the .short work-sheet may be readily inserted from the front, and after the work-sheet is thus inserted, the platen' rise to a guiding position. In order to en-` able the typist to have both hands free while inserting the `work-sheet, there may be provided a handle or linger-piece which is adapted to be actuated to raise the platen to the sheet-inserting point or position,A and to detain it there when so raised. Where the invention is applied to a `fan-fold billing machine oi thetype above described, the

connections may be such that the usual' diS-v placement or swinging of the platen, by which the front paper-table yis brought to a horizontal position, will not be 4interfered with.

In order Ato facilitate the insertion of the outside sheet, the usual knife for severing thecfan-fold sheets may be caused to swing rearwardly and downwardly toward the sheet-guide which rises from the paper-table,

so that the knife assists in forming a continuousguide to carry the inserted sheet around the platen.

Other features and advantages will hereinafter appear. y

In the accompanying drawings,

Figure l is a fragmentary sectional side view of a fan-fold typewriting machine, showing the present invention as applied thereto.

Fig. 2 is a view similar to Fig. l, but n omitting a number of parts, and showing V the handle, which swings upthe platen, actuated far enough to release the usual platenswing-frame of the fan-fold-machine. Fig. 3 is a view similar to Fig. 2, lbut show* ing the handle actuated far enough to have lifted the platen and latched `it in its intermediate sheet-inserting raised position.

- Fig. l is a view similar to Fig. 1, omitting many parts,'but showing-the swingy frame l swung up in the usual gaging operation of a fan-fold billing machine.

Fig. 5 is a perspective view of most of the parts seen in Fig. l, and including a vfew other parts of the typewriter.

Fig. 6 is a front view of the rig'rht-hand` end of the parts seen in Fig. 5.

Fig. 7 is a perspective view ofthe Sheetguide for guiding the inserted work-sheet rearwardly and upwardly.

Fig. 8 is a perspective view of the rear'or bottom paper-table or apron, showing the depressions for accommodating the guide of Fig. 7.

In the usual fan-fold billing machine, a web 10, herein shown as comprising three plies or layers, is drawn forwardly over the rear bar 11 of the usual extension 12 of the typewriter carriage. Upon this extension runs the usual carbon-paper carriage 13 having clip bars 14 for carbon-sheets 15, which are interleaved between the layers of the web 10.

In the ordinary operation of gaging a web 10 upon the machine, the platen 16 is swung upwardly to the Fig. 4 position, by first pushing rearwardly a handle 17 to release a catch 18 overlying a holding roll or pin 19 upon a swing frame 20. IVhen the swing frame 2O is thus released., the typist usually seizes the upstanding extension 21 of the front paper-table 22, which forms part of the swing frame, and swings the swing frame forwardly to the Fig. 4 'position, so that it rests upon the support 21, and then draws forwardly upon the webs 10, gaging them against the usual adjustable end gage 23 upon the extension 21. While holding the webs thus gaged, the typist usually pushes the carbon-paper carriage 13 rearwardly by thc usual handle, not shown,

and then swings the swing frame rear-A wardly to carry the platen 16 against the usual rear feed-rolls 24 and front feed-rolls 25. Usually after this the typist severs the gaged web by drawing it against the knife 26, and then proceeds to write by actuating the types 27 to print upon the platen on the usual printing line.

According to the present disclosure of my invention, the platen may be lifted to an intermediate sheet-inserting position and held there. For this purpose, there is provided a handle 28 which normally occupies the Fig. 1 position, and which is adapted to be drawn forward. swinging it around its journal 29 in the side piece 30 of the swing frame 20. This swinging of the handle carries around with it a cam follower arm 30", having a follower pin or roll 31, which underlies a cam 32 fast upon the rod or shaft 33, which carries the swing frame hook or catch 18 at each end of the swing frame. When the handle 28 is drawn forward to the Fig. 2 position, in which it is shown substantially upright, it has completely released the hooks 18, and is detained at this angle upon the swing frame 20, because a spring detent 34 seats itself in a depression 35 in the hub 36, which is fast to the handle 28. In swinging to this position, the han llc 28 also swings rearwardly an extension 37 of the follower arm or plate 30, and causes a pin 38 therein to draw rearwardly a link 39, which has a slot 40, against the rear end 'of which the pin 38 normally rests. In

thus drawing the link 39, the link swings downwardly the knife 26 from the Fig. 1 to the Fig. 2 position, thus carrying the knife backwardly along the webs if they have been previously severed, and preventing them from slipping out of place during' the ensuing rising of the platen. The connections for doing this include a pivoted arm 41 to which the link 39 pivoted, saidL arm carrying at its end a cam pin 42, which rides in a cam slot 43 of a plate 44 forming a lever journaled on the platen axle 45. and carrying at its front end 46 the knife 26. Further forward drawing of the handle 28 causes the pin 42 to strike the rear end of its cam slot 43, as in Fig. 2, with the result that the handle 28 draws on the plate 44 and positively swings the swing frame 2l) and the platen upward until they reach the Fig. 3 position, at which position the swing c frame is detained because a. rear arni i8 thereon carries its detent 49 into the depres sion 50 of a supporting spring 51, said spring being strong enough to hold the swing frame in this upper position, with the platen 16 now at its intermediate sheet-insertingpoint or position. In this position the platen 16 is above and clear of the printing point indicated by the type-head 27, and is therefore above and clear of the usual front cooperating elements (not shown) such as the usual type-guide and ribbon-vibrator and ribbon, thereby providing a clearance for the insertion of a work-sheet backwardly. from the front down at the front of and around below the platen.

When the parts are in this position, the typist has both hands free and may hold (Fig. 3) the webs 10 with the thumb or UgGl' llainst the front of the platen or now substantially vertical front papertable 22, while inserting with the other hand a front sheet 52 and an associated carbon The sheet 52 and, carbon slip down and are guided by the inner side of the knife 26 and then strike against the curved surface of a paper-guide 54 which includes arms or fingers normally lying within openings or depressions of the curved rear paper-table or bottoni paper-apron 57, as in Fig. 1, but which are swung up to the Fig. 3 position by the rising of the platen. The connections fo'.` causing the rising of the fingers 55 include a link 58, which is pivoted to a hub 59 of the swing frame where it is journaled upon the usual rod or shaft 60, said link including an elbow 61 to curve over the usual pinion 62, and also including a rearwardly-extending stretch 63 which is pivoted to the guide 54 at an Vear 64, The forward swinging of the swing frame swings the pivot of the link 58 foiwvardlv and thereby drawson-the earv 64, thus rocking the arms upwardly because they spring froma bail orcrossgage 73 upon the front paper-table.

piece 66 lying below the rod 33 and journaled thereon by ears 68 at the top thereof. The arms 55 extend forward through an opening 69 in the rear paper-table 57, as appears in Figs. 1, 2,- 3 and 4. The pivot 65 is far enough from the axis of the shaft 60 to swing the arms 55 up so that they will Iinst contact with' the knife 26, as seen lat Fig. 3.

The angle between the knife 26 and the arms 55 is soyslight that the front sheet 52, which is being inserted, readily bends rearwardly and slides rearwardly upon the arms 55 and slips into the opening 69 in the apron 57, so that it is carried beneath the rod 33 and, therefore, is not liable to be doubled up by the friction of theweb 10, as might occur if it were attempted to thrust the sheet between the webs 10 and the usual cover plate 7() which overlies the rod or bar 33.

In orderto make sure that the sheet 52 when thus thrust rearwardlv will pass beneaththe rod 33, the usual cover plate is provided with a forwardly-extending plate 71, against which the webs 10 may lie normally, and which carries a deflecting imderpiece 72, which bends the sheet 52 slightly downwardly if necessary t0 cause it to pass beneath the rod 33. The apron 57, the cover plate 7() and its extension 71 are shown in the drawings as formed in a single 1ece. f p lVhen the sheet 52 has thus been inserted, it may be gaged against an adjustable side Ifit be desired to separately gage the end of the inserted sheet 52, the work-sheets and the webs 10, instead of being gaged, as in Fig. 4;, may

be passed through a slit 74, so that they pass behind the front table 22, and may be gaged against any suitable gage, while the worksheet52 may be gaged against a leading edge gage', not shown, lying upon the worktable, or it may be gaged against the adjustable gage 23, which, for this purpose, may be moved down toward the front papertable 22. Y

When the work-sheet 52 has been thus inserted and gaged, the platen may be swung back against the feed- rolls 24 and 25 by a rearward movement ofthe handle 28, whereupon the hooks 18 will hook it down, being swung forward byv the usual spring 7 There may be provided a handle 7 6 for moving the knife 26 rearwardly and downwardly against the tension of its returning spring 76a without, however, Vraising the platen. For this purpose, the handle 7 6 is fast to a short shaft 77, upon which the arm l11 is also fast, with tthe result that actuating the handle 76 will' swing the plate 214 and consequently the knife 26.

In order to prevent the handle 28 from rattling or from 'falling out of position when the swing frame is swung to the Fig.

4c position, the detent spring 34 may normally rest in a depression 78 in the hub 36.

The bottom paper-table 57 may be of .much the usual form below the opening r69 except for the depressions 56, and thusacoommodate the feed-rolls, which may be substantially of the usual form, but so spaced that the arms 55 may rest upon the rear feed-roll shaft 79.

It will be noted that the arms 55 rise tothe Fig. 1 position even if the handle 28 vis not actuated, because the swinging of the swing frame 2O lifts them. This, however, does not interfere with the threading or drawing forward of the webs 10, as' shown in Fig. 1, since the arms 55 lie far below the webs 10. The pinion 62 forms part of the connection of the line-space handle 80 to the platen 16, one form of said connection being disclosed in the patent to VVernery t Smith, No. 1,132,055, dated March 16, 1915.

Owing-*to the slack created in the web 10 vby the lifting of the platen, the web'will lie upon the :lingers 55 when the platen is lifted by the handle 28, and to insert the sheet 52, the web Ashould be lifted by` the thumb and linger clear of the fingers 55, as is shown in Fig. 3. This gives the sheet 52 a free path to the opening below the deflector 72 and above the cross-piece 66, so that it may project beneath the carriage eXtension l2.

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