' vJ'ZES SE A. B. SMITH, F STAMFORD, CONNECTIC'O'T, ASSIGNOR '10 UNDERWOOID TYPE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWERE.

TYPEWRITING MACHINE.

Application filed March 26, 1924. Serial No. 701,913.

To all whom it may concern:

Be it known that I, Jnssn 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 Typewriti a web composed of several plies may have the platen being swung up to release the',

successive forms or bills printed thereon, said plies being interleaved with carbonsheets and fed around a cylindrical platen,

web, to facilitateshifting of the carbonsheets to a fresh portion of the web.

More particularly, the invention relates to' tally-strip or record-sheet feeding mechanism to be used in such'machines. In In co-pending application No. 696,556,. filed March 3, 1924, provision is made to linea space a tally-sheet once for each bill-length, so that the names or items appearing on the successive bills may be copied in condensed form on the tally-sheet.

An object of the present invention is to line-space the tally-sheet for each line-spacing operation of the bill-sheet, so that all of the items typed on the bill are copied on the tally-sheet. Preferably these items are copied in condensed form on the tally-sheet. For example, the items copied on the tallysheet may bearranged at single line-space intervals, while the items on the bill-sheetmay be arranged at two or three line-space intervals.

A'take-up roll or receiving roll is provided to feed the tally-sheet, the leading end of which is connected to said take-up roll. Said take-up roll is connected with the platen line-spacing mechanism to enable the tally-sheet and the bill-sheet to be linespaced simultaneously by the actuation of the regular line-space handle. To this end the platen line-spacing mechanism comprises the usual line-space slide which is supported on the platenframe, and the tally-strip line-spacing mechanism comprises a linespace slide "which may be supported on the carriage-frame, and there is secured to one of said slides an .arm extending to the other slide, to connect said slides, so that said slides may be operated simultaneously. Since the platen line-s acing mechanism is carried by the platen-firame and the tallysheet line-spacing means is supported on the carriage-frame, provision is herein made by means of a slot in-said connecting arm to enable the platen line-spacing mechanism to be freely shifted relatively to the tally-sheet line-spacing mechanism during case-shifting movements of said platen.

A feature of the invention relates to the connection from the platen line-spacing mechanism to, the take-up roll for the tallysheet, which is constructed to enable the swing-frame to be freely o erated to swing the platen in order to facilitate the shifting of the carbon-sheets. To this end, the takeup. roll has secured thereto a ratchet-wheel which forms part of its line-spacing mechanism, and which may be swung away from a relatively-fixed co-operating pawl when the platen is so actuated.

'Another feature of the invention resides in the provision of a carbon-sheet for the tally-sheet or strip, which may be connected to the regular carbon-carrier of the continuous billing machine, so that it may be retracted with the carbon-sheets interleaved between the-plies of the bill-web.

In order to condense the items copied on the tally-sheet, the tally-sheet is usually fed slower than the bill-sheet, and it is common practice to feed the tally carbon-sheet at the same speed as the tally-sheet. If the tally carbon-sheet were fed at the same speed as the tally-sheet in-the present machine, however, in which the tally-sheet also moves at a'slower speed than the bill-web, and in which, it will be remembered, the tally carbon-sheet is connected to the carbon-carrier, which travels at a faster speed than that of the tally-sheet, the tally carbon-sheet would buckle or pile up behind the platen, because its rear end would be advanced faster by the carbon-carrier than its forward end is advanced by 'means of the take-up roll. Another feature of the invention is to prevent buckling of the tally carbon-sheet. To this end it is fed faster than the tally-sheet, preferably at the same speed as the bill-web, and consequently at the same speed as the carbon-carrier to which it is connected. For this purpose, the tally carbon-sheet is made relates to means'to overcome this tendency.

To this end there is provided a friction device, which is referably located behind she platen and is e ective to engage the tallysheet, to thus prevent said tally-sheet from being accidentally advanced at an undesired speed.

Other features and advantages will here-' inafier appear.

In the accompanying drawings, Figure 1 is a side elevation, showing the carriage of a continuous billing typewriting machine, with my invention applied thereto. Figure 2 is a fragmentary top plan riew of the parts shown in Figure 1.

Figure 3, is a diagrammatic side View, showing the parts in position when the laten is swungup to release the work-web to facilitate the shifting of the carbon-sheets.

Figure 4 is a diagrammatic front view,- showing the arrangement of bill-web, tally-.

sheet and the carbon-sheets with relation to each other, and also with relation to the feederollers.

Figure 5 is a View similar to Figure 4, but shows another arrangement of the tally- .sheet with relation to the work-web and the feed-rollers.

The invention isshown applied to an Underwood continuous billing machine in which type-bars 10, when operated by l-ieys (not shown), swing upwardly and rearwardly to print against the front of a cylindrical platen 11. The platen is mounted in a platen-shift-f'rame- 12, which is supported in a carriagre-frame 13 for caseshifting movements, to enable the platen to be brought into co-operative relation with lower-case types 14" or' upper-case types "15 on the type-bars.

A web-supporting table 16 extends rearwardly from the platen, over which a: composite work-web 17 may be advanced from any suitable source of supply to the platen to be typed'upon, said composite web being composed of separate plies 18 with carbonsheets- 19 interleaved between them, and

which maybe fed around said platen by feed-rolls 21 hearing against the under side thereof. -The table 16 is connected to ihe carriage-frame 13 in )the usual way by brackets 20 secured to said carriage-frame to travel. with thecarriage during letterspacing movement s thereof, said table being guided in "the usual way, as shown in the Wernery & Smith patent above referred to.

The carbon-sheets are'attached, .at theirrear ends, to individual bars 22 on a carbon-ear rier 22, which is mounted on the web sup? porting table 16 in a manner to be moved f back and forth on said table, or, in other -words, towards the platen,-with the carbonsheets 19 while the composite web is fed around the platen and away from the platen in order to shift the carbon-sheets to afresh portion of the. composite web. The

composite web. may beprovided with 1"egu.-' I

lar forms or bills of equal length printed thereon, as is well understood in the art, and n after'a bill or set of superposed bills has been completed, the carbon-sheets 19 are retracted or shifted to a succeeding set .of bills by means of the carbon-carrier, which is actuated by a handle 23 and arrested by I an adjustable stop 24.- The bill-web 17 is thenpulled forward against a gage 23 on 'a gage-bar 26 to position the typed set of bills prior to severing them from the web.

To facilitate the shifting ofthe carbonsheets and the'gaging ofthe typed bills, the

platen may be swung upto an abnormal position, shown in Figure 3, to enable the web to be straightened out, so. that, the-carbonsheets may be readily -shifted relatively ported ina swing frame 27, Figure 1, pivotally mounted at 28 in the platen-frame 12, in a manner similar to that disclosed in the thereto. For this purpose, the platen is sup-- application of -William' F. Helmond, Serial I.

No.1 609,560, filed December 29,- 1922.

The platen line-spacing mechanism may include a line-space wheel 29, which may be connected to the platen, as in said Helmond application, to enable the swinging move- ,ment of said platen. The line-space wheel is operated by a spring-pressed pawl 29 pivotally supported on a line-space slide 30 suitably supported on the platen-frame 12,

said slide being actuable by. the usual linespace handle (not shown) against the ten- .sion ofa return spring 3 l.

A record-sheet or tally-sheet 32 is provarious bills are copied. The record-sheet is fed from any. suitable source of supply, which may be located at the back of ,the machine, and is conducted over the webtable 16 and the carbon-carrier thereon, and then downwardly at the front of said table with the bill-web 17 towards and around said platen past the printing point.

It is desirable to have the items copiedon the tally-sheet in condensed form. Consequently there is provided means which may comprise a separate line-spacing mechanism for said tally-sheet, so that it. may

saidplaten, and upwardly at the front of' 1 15 'vided, upon which the items typed on the be fed slower than the bill-web. To this end, the leading edge of the tally-sheet 32 is secured to a take-up roll 33 fixed to a shaft 34 revolubly supported in brackets 35 secured to the platen-swing-frame 27. The shaft is provided at one end with a ratchet-wheel 36 to be actuated to revolve the shaft, and consequently the roll 33thereon, in a clockwise direction by a springpressed pawl 37 supported on a slide 38,

which may be reciprocated in a bracket 39' secured to one of the tablesupporting brackets 20.

Connection between the tally-sheet linespacing slide 38 and the platen line-spacing slide 30 is made so that they may be operated simultaneously by the actuation of the usual line-spacing handle (not shown), which engages the platen line-space slide 30. Said connection may comprise an extension or arm 40, which is herein shown secured to the platen line-space slide 30, and which extends upwardly to the recordsheet line-space slide 38. Said armhas at its upper end a slot 41 to receive a lateral extension 42 on said slide 38 to connect it with said slide. It will be noted that the platen line-spacing mechanism'is supported on theplaten-frame, which, it will be remembered, is shiftable from lower-case position to upper-case position, and that the line-space slide 38 for the tally-sheet is supported on the carriage-frame 13, which is relatively fixed. Consequently provision is made by extending the slot 41 downwardly in said arm 40, to enable the arm to be shifted with the platen relatively to the line-space slide 38 which it operates.

The platen line-space slide 30 always moves through the same linear distance, as

' in the Underwood machine, irrespective of the number of line-spaces imparted to the platen by each operation of said slide,t he

line-spacing mechanism being settable by a line-space control-lever 43, to enable the platen to be line-spaced one, two or three line-space distances at each actuation of the line-space slide, according to the setting of said control lever. Said control lever is connected to a pawl-controlling element 44 having a shelf 45 thereon over which an extension 46 of the line-spacepawl rides,

arm 40 is to one side of the bracket 39 (Figure 2), so that not to be obstructed in its movement by said bracket.

It will be understood that the relation between the line-space wheel 36, associated with the take-up roll 33, and its co-operating line-space pawl 37, is such that said linespace wheel may readily be swung away from the pawl during a platen-swinging operation, and when the platen is again lowered to its typing position that the linespace wheel is brought back by the swingframe into effective relation with the linespace pawl.

A carbon-sheet 47 is provided for the tally-sheet, said carbon-sheet being connected at its rear end to a carbon-blade 48 supported on the carbon-carrier 22, so that said carbon-sheet may be retracted, with the other carbon-sheets 19, to a fresh portion of the tally-sheet at each carbon-displacing operation. Since the tally carbon-sheet 47 is connected with the carbon-carrier 22,.which movesat the same speed as the bill-web 17 and faster than the tally-sheet 32, it is desirable to feed the tally carbon-sheet at the same speed as the bill-web, and faster than the tally-sheet, to prevent buckling of said tally carbon-sheet 47, which would ordinarily occur, in the present machine, if the tally carbon-sheet were fed at the same speed as the tally-sheet 32.

To enable the tally carbon-sheet 47 to be fed with the bill-web 17, it extends considerably beyond the right-hand edge of the tally-sheet 32 (Figure 4), so that it may be fed by means of the feed-rolls 21, which are located to one side of the tally-sheet 32, 'so that the latter may be fed independently of the bill-web. The tally-sheet may be located in the middle of the bill-web, as shown in Figure 5, instead of the lefthand end thereof, as shown in Figure 4, and in which case the feed-rolls 21 are arranged one near each side of the billweb. 17 and beyond the sides of the tallysheet 32.

Since the tally-sheet is nearest the platen, there may be suflicient friction caused by the bill-web at times to tend to advance the tally-sheet at the same speed as the billweb, which Wouldbe objectionable since it is desired to feed the tally-sheet at a slower speed in order to condense the typed items thereon. To overcome any such tendency, however, there is provided a friction device comprising a spring-pressed bar 50 cooperating with a bar 51 secured to the websupporting table 16 by screws 52, the'tallysheetpassing between said bars. It will be understood that this friction device will not interfere with the adavancement of the tally-sheet around the platen since said tallylOl up roll 33 to which, it will be remembered,

, the leading end of the record-sheet is atspacing mechanism comprising a line-space wheel on said swing-frame for the recordtached.
