TYPEWRITING MACHINE.

Application filed May 3,

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 F airfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines of the class in which provision is made to straighten out the work which is fed around a. cylindrical platen, so that the carbon-sheets, which are interleaved between the plies of the work, may be pulled back relatively to the latter, one well-known form of machine of this class being disclosed in the patent to W'ernery and Smith, No. 1,132,055, dated March 16, 1915,

In a machine of the fan-fold type, such as that disclosed in said patent, it is customary to type on the outside ply of a fan-fold web and concomitantly make carbon copies on the underlying plies, all of the plies advancing together through the machine and being severed sii'nultaneously. The orginal and carbon copies may also be made on a plurality of independent superposed webs or plies which, as in the case of a fan-fold web, are advanced through the machine together and are drawn off or severed simultaneously. Usually each of the super-' posed webs of plies consists of a succession of similar forms which may be of considerable length although there may not be more than two or three lines of typing on each form. This would result in considerable waste of space between the successive entries on an inner work-sheet or record-sheet. It is desirable, however, to have the records, or carbon copies thereof, typed on numerous successive forms, closely succeed each other on the record-sheet, which may be entirely separate from the plies or webs lying outside thereof. such a record-sheet being ordinarily referred to as a condensed record-sheet.-

This result has been effected by holding the condensed record-sheet stationary while the webs or plies outside thereof are advanced in the machine at the conclusion of the typ ing of each form.

The main object of the present inventlon, is to provide novel and effective means for controlling the record-sheet and associated webs or plies provided with successive forms, so as to obtain in condensed form on the 1922. Serial No. 558,139.

record-sheet records or copies of the entries on the successive forms.

According to the present invention,'provlsion may be made of a clamp whereby the record-sheet, passed between the platen and the front paper-table or collating table, may be clamped to the back of the latter. This arrangement renders it convenient to insert the record-sheet, and, due to the position in which the record-sheet is clamped, permits use to be made of a record-sheet of any desired width and placed so as to underlie any desired portion of the superposed webs having forms thereon.

Another feature consists in provision of means whereby, when the collating table is in its normal position, the clamp will be ineffective to hold the record-sheet against the back of the collating table, but, upon movement of the paper-table to permit the webs to be straightened beneath the platen, the clamp will be rendered eiiective to hold the record-sheet against movement relative to the collating table. Provision may also be made of a finger-piece whereby the clamp may be rendered ineffective at will.

If the headings on the various forms are of considerable depth, it will be necessary after severing the used forms to advance the webs to bring the desired portion of the next set of forms to the printing line. This would cause the record-sheet to be advanced and a gap to be left on the latter between the preceding record and the one to be made in connection with the superposed forms in position to receive an entry. To avoid this unsatisfactory condition, provision is made of severing means so positioned that, when a set of used forms has been severed, the next set of superposed forms will be positioned for typing thereon. This severing device, which may be in addition to the usual paperguiding and severing knife, may be adjustable to different positionsrelative to the printing line, so that it may be positioned readily for forms having different depths of headings.

In as much as the record-sheet is entirely separate from the superposed plies carrying the successive forms, the record-sheet may be inserted while the webs and associated carbons are in the machine and, when inserted at 'the introductory side of the platen, will be guided around the latter by said webs and carbons to the delivery side of the platen adjacent the lower edge of the collating table. Preferably, the insertion of the recordheet is effected when the webs are in straightened position beneath the platen.

The lower edge of the collating table, however, lies close to the platen, and it is desirable to provide means whereby the leading edge of the record-sheet will be guided between the collating table and the platen. To this end, provision may be made of a stripper in the-form of a paper-finger mounted on the back of the collating table and extending below the lower edge of the latter and having its end flared outwardly from the axis of the platen, so that, when the record-sheet is thrust forward with the corresponding front corner in advanced position, the advanced corner will pass back of the flared end of the guiding finger and will be stripped and guided thereby between the collating table and the stationary platen, and the stationary superposed webs and associated carbons which support the recordsheet thus stripping the latter from the webs, so as to insure the passage of the leading edge of the record-sheet back of the guiding finger. Following the introduction of one corner of the record-sheet between the lower edge of the collating table and the platen, further advancev of the record-sheet will cause its inclined leading edge to ride over the lower edge of the collating table until the leading end of the record-sheet lies between the lower edge of the collating table and the platen throughout its whole width. The record-sheet may then be adjusted in position both longitudinally and transversely. To assist in aligning the record-sheet, when so introduced, provision may be made of a side gage at the rear of the collating table. Preferably the side gage at the rear of the collating table constitutes an extension of the guiding finger, thus making it convenient to apply these devices to the rear face of the collating table or to remove them therefrom simultaneously.

\Vhen a record-sheet is to be inserted, the collating table is preferably swung to horizontal position to permit the webs and associated carbons to be straightened beneath the platen, and the record-sheet is thrust forward from the rear and guided by means of the offset guiding finger to the rear of the collating table, the finger-piece on the back of the collating table being depressed to permit the leading edge of the record-sheet to pass between the clamp and the rear face of the collating table. In such movement of the record-sheet its leading edge may engage the lower end of the usual gage-bar-or the usual screw by which the ge-bar is attached to the rear of the collating table. To prevent such interference with the forward movement of the record-sheet provision may be made of means to deflect the leading edge of the record-sheet over the end of the gage-bar and its attached screw. Preferably, said deflecting means comprises two deflectors, one on each side of the gage-bar.

Provision may also be made of side gages adjustable along a bar supported by its ends on brackets attached to the carriage at its rear, the bar being slightly to the rear of the upper edge of the'rear paper-table. Heretofore side gages have been mounted on the usual rock-shaft forming part of the latching means for the usual swing-frame and extending across the carriage below the upper portion of the rear paper-table in such a manner that the rear paper-table practically prevents any adjustment of the sidegages. It will be evident that the new arrangement renders it possible to adjust the side gages for any desired width of web.

Other features and advantages will hereinafter appear.

Figure 6 is a view similar to Figure 4, but with the rearward extension of the carriage omitted, and showing the latching device for the platendisplacing frame in the releasing position and the record-sheet clamped to the back of the collating table.

Figure 7 is a view similar to Figurefi, but showing the platen displaced, the col lating table being substantially horizontal.

A platen 10 is fixedly mounted on a shaft or axle 11 journaled in ends 12 and 13 of a platen-dis lacing frame indicated in general y 14. e ends 12 and 13 of the platendisplacing frame 14 are pivotally mounted on a rod 15 supported at its ends by ends 16 and 17 of a typewriter-carriage 18. The typewriter-carriage also includes a rear paper-table 19, and carries front and rear feed-rolls 20 and 21, respectively, to co-operate with the platen in its normal position for feeding work-sheets therearound.

To turn the platen 10, provision is made of astub-shaft 22 journaled in the end 16 of the carriage, and having at its inner end a .gear 23 meshing with a broad pinion 24 on the rod 15. The broad pinion 24 also meshes with a gear 25 at the left-hand end of the platen-axle 11, the gear 25 being of the same size as the gear 23. The platen may be rotated by rotating the stub-shaft 22 by means of a nger-wheel 26 thereon, or by t e usual line-spacing means, not shown. Provision may also be made, at the right end of the carriage, of a finger-wheel 27, a stub-shaft 28 and gears 29 and 30 meshing with a broad pinion 31, the arrangement of these elements being substantially the same as those of the corresponding elements at the left endoftlie carriage.

Connected to a cross-bar 32 of the carriage 18, by means of brackets 33, is a rearward extension 34 of the carriage 18, said rearward extension comprising rails on which run grooved wheels 36 on the bottom of a carbon-carrier 37. The carbon-carrier 37 comprises carbon-holders or bars 38 to which the rear ends of carbon-sheets 39 are attached and between which webs or worksheets 40 are threaded.

The webs 40 and interleaved carbon-sheets 39 extend forwardly above a bar or rod 41 supported at the rear of the carriage 18 by means of brackets 42, and between adjustable side gages 43 mou'nte'don the rod 41. The side gages 43 may be secured in adjusted position by any suitable means, such as screws 43. e webs and carbon-sheets then pass over a raised portion 44 of the rear paper-table 19 and between .the latter and the platen around to the delivery side of the latter. From the delivery side of the platen the webs pass upwardly between the platen and the usual knife 45 to the upper surface of a collating table 46 supported on the ends 12 and v 13 of the platen-displacing frame 14. The paper-table 46 is stiffened by across-bar 47 constituting in effect a part of the collating table 46, and a gage-bar 48 of the usual form is detachably secured to the cross-bar ,47- by suitable means, such as a screw-49,

having a knurled head. An adjustable gage 50 of the usual formis mounted on the gagebar 48.

A rock-shaft 51 extends across the carriage beneath the raised portion 44 of the rear paper-table and is journaled in the ends 16 and 17 of the carriage 18. When the platendisplacing frame 14 is in its normal position,

' the ends 12 and 13 thereof rest on the shaft 51 and the frame 14 is held in this position by left and right-hand latches 52 and 53,

respectively, both fixedly mounted on the shaft 51 and co-operating with studs 52 and 53*, projecting inwardly from the ends 12 and 13, respectively, to hold the frame 14 in its normal position. This shaft is normally urged to swing the latches 52 and 53 to effective position by means of coiled I springs 54 and 55 at the left and right ends, respect1vely, of the shaft 51. To release the latches, provision is made of a fingerpiece 56 forming an extension of the lefthand latch 52.

Each of the webs 40 may consist of a succession of similar forms, and, upon completion ofthe typing on one set of superposed forms, the webs must be advanced sufliciently to enable the set of used forms to be severed. It is desirable, however, to have carbon copies of the matter typed on the different sets of forms in condensed form on a singlerecord-sheet 57. To obtain this result, the record-sheet must be held against movement while the webs are advanced to the severing position at the conclusion of the typing of each set of superposed forms.

According to the present invention, the record-sheet is clamped against movement with reference to the collating table 46, and, as herein disclosed, this is done by means of a bail 58 having-arms 59 pivoted on screws 60threaded into the ends 12 and 13 of the platen-displacing frame 14, and a cross-bar 61 having thereon friction members 62 of suitable material to co-operate with the bar 47 at the back of the collating table to grip the record-sheet 57. Springs 63 coiled about the screws 60 tend to swing the bail 58 to effective position. Each of the arms 59, at the rear of the screw 60. on which it is pivoted, curves upwardly and forwardly, and at its end is provided with a stud 64 projecting outwardly therefrom to lie in the path of the hook portion of the adjacent latch of the latches 52 and 53, so that, when the frame 14 is in its normal position and said latches 52 and 53 are swung to effective position, the bail 58 will be swung to ineffective position to enable the record-sheet 57 to be fed by the platen. Provision may also be made of a finger-piece 65 mounted on the left-hand arm 59 whereby the clamping bail may be moved to ineffective position.

Usually the distance from the printing point to the cutting edge of the knife, in a is made of a knife 66 adjustably mounted platen-displam on the ends 12 and 13 of the ing frame 14, theusual knife eing reta ned to perform its function of sheet-guidlng. Preferably, this adjustment is obtained by extend screws 69 threaded into the adj acentend of the frame 14. It will be evident that by loosening the screws 69 the knife 66 may be moved to different positions with reference to the printing line and clamped in these positions by tightening the screws 69. This arrangement avoids thenccessity of feeding the webs forwardly after the severing operation, and permits the matter'on successive forms to be copied on the recordsheet without leaving unnecessary spaces between the copies of successive forms.

The lower edge of the collating table 46 lies very close to the platen 10, and in order to assist in guiding the leading edge of the record-sheet 57, inserted from the rear between the carbons 39 and webs 40 and the platen, between the collating table 46 and the platen 10, provision is made of a guiding finger 70. This finger is secured to the rear face of the collating table at the lefthand of the latter and at the end of the platen 10. As shown in Figure 3, the finger 70, which is secured to the cross-bar 47 by means of a screw 71 having a knurled head, is flared outwardly at its lower end, and at its other end there is a support 72 for a side gage 73 extending around the rear edge of the collating table toward the front thereof. When a record-sheet 57 is to be inserted, the finger-piece 56 is swung to the rear to release the platen-displacing frame 14, and the latter is swung forwardly aroundthe rod 15 until the collating table rests upon an abutment 74 on the front rail 75 of the carriage 18. Preferably, the abutment 74 is of yielding material such as rubber. It is to be understood that at this-time the webs 40 are in proper position for starting typing on a new form and the carbons 39 are in retracted position. At this time the webs 40 and the carbons 39 will be held in proper position relative to the collating table by means of the usual knife 45 and the adjustable knife 66. \Vhen, therefore, a record sheet is inserted at the rear of the platen between the webs 40 and the carbon-sheets 39 on one hand and the platen 10 on the other, as indicated in Figures 2 and 7, the left-hand forward corner of the sheet will be directed above the flared end of the finger 70. and will be-guided thereby between the collating table 46 and the platen 10. As shown in Figure 2, the record-sheet is thrust forward with its leading edge in inclined position. and it will be evident that, after the left forward corner has been introduced between the collating table 46 and the platen, further movement of the record-sheet will cause the inclined leading edge of the recordsheet to ride over the lower edge of the collating table and pass between the latter the side gag and the platen. The record-sheet may be straightened in the machine and gaged by e 73 carried by the finger 70. In this gaging operation use may also be made of the adjustable gages 43 at the rear of the carriage 18.

When the collating table is in the position shown in Figure 7, the clamping bail 58 Wlll be in effective position. It is desirable, however, that the record-sheet 57, as it is guided between the collating table 46 and the platen,

be permitted to pass along the rear face of said collating table. To permit such action, the finger-piece 65 may be depressed to Slllft the clamping bail 58 to lHBll EOtlVB POSItIQH, further movement of the record-sheet, Figure 7, serving to move the latter between the clamping bail 58 and the cross-bar 47 at the rear of the collating table. 'It will be seen that, as the finger 70 is mounted on the rear face of the cross-bar 47, the leading edge of the record-sheet will to the rear of the cross-bar. When the record-sheet is properly adjusted, the fingerpiece 65 may be released to permit the clamping bail 58 to press the record-sheet against the collating table and hold it fixed relatively thereto. The swing frame 14 may then be swung to its normal position and there held by means of the latches 52,- and 53, the latter, in their movement to effective position, releasing the record-sheet 57 so that it may be fed with the webs 40 upon line-space movement of the platen. After the insertion of the record-sheet, as just explained, and upon the return of the platen to its normal position, typing may be effected on the properly positioned set of superposed forms in the usual manner, and, upon completion of such typing, the displacing frame 14 may be swung forwardly to its Figure7 position, the clamping bail 58 being made effective automatically by the releasing of the frame 14 by the latches 52 and 53. The webs 40 may then be drawn forwardly and ga ed by means of the gage 50, and thecar on-sheets 39 restored to their rearward position by means of the carbon-carrier 37. The platen may then be restored to its normal position and the used forms severed over knife 66, this operation being repeated for each set of superposed forms.

When a separate record-sheet is used in the fan-fold machine, the upper carbon 39 will not be guided from the platen over the lower edge of the collating table 46, inasmuch as the record-sheet passes back of the collating table. This may cause trouble as a result of the engagement of the leading edge of the upper carbon-sheet with the lower edgeof the collating table 46, a condition which would result in damage to the carbon-sheet. To obviate this trouble, the upper carbon 39 may be made longer than the others and of sufiieient length to extend over the lowerpart of the collating table 46 when the carbon-carrier 37 is in its rearward position. This arrangement will insure proper feeding of the upper carbon 39 over the collating table 46 when advanced by the platen.

When the record-sheet 57 is moved past the bar'61 of the clamping bail, the forward edge of the record-sheet tends to engage and to be obstructed by the screw 49 by which the gage-bar .48 is secured to the collating table 46. To avoid this difliculty, provision has been made of suitable deflectors 76 mounted on the cross-bar 47 on opposite sides of the gage-bar 48.

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