SPECIFICATION forming part of Letters Patent No. 719,300, dated January 27, 1903.

Application filed April 5, 1901. Serial No. 54.462. (No model.)

[ to whom, it may concern:

Be it known that we, DANIEL BRIGGS and STEPHEN I-I. FARNHAM, citizens of the United States, and residents of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in TypelVriting Machines, of which the following is a specification.

This invention relates to the paper-feeding devices of type-writing machines, and particularly to means for making carbon records of type-written bills or other memoranda, several of which are to be carbonized or manifolded upon asingle recordsheet. One

bill-head may be inserted in the type-writing machine, together with a record-sheet and a carbon or transfer sheet, without difficulty; but it is difficult to remove the bill without disturbing the record-sheet and insert a second bill-head in such a position that the carbonized copy thereof shall appear in its proper place below the first bill upon the record-sheet, and it is also difiicult to remove the second bill and insert the third and succeeding bill-heads so that the duplicates shall appear in their proper places upon the rec ord-sheet. Moreover, in order to avoid the liability of overlapping it becomes necessary to unduly separate the carbon entries, thus tending to waste the space upon the recordsheet.

The main objects of our invention are to facilitate the operation of making continuous 5 carbon records of separate bills and to condense the entries upon the record sheets without incurring the liability of overlap ping.

In practicing our invention we preferably employ a roll or web of paper having billheads printed thereon in succession, each bill-head being separated from the next by a printed or perforated line, and after making out each bill we tear it off from the web at said line; but it will be understood that separate bill-heads may be employed, if desired.

Our invention consists in certain combinations of devices, features of construction, and arrangements of parts, all as will be hereinafter more fully set forth, and particularly pointed out in the concluding claims.

In the accompanying drawings, Figure 1 is a plan of the upper portion of a Remington No. 8 type-writing machine, showing our improvements applied thereto. Fig. 2 is an elevation taken at the left-hand end of Fig. 1. At Figs. 1 and 2 are indicated portions of a tabulating mechanism of the wellknown Gorin type. Fig. 3 shows a cross-section of the platen and platen-frame. Fig. 4 is a front elevation of a bill-severing blade, showing the manner of mounting the same upon the front bar of the platen-frame. Fig. 5 is a sectional front View showing various devices which are mounted in rear of the platen. Fig. 6 is an end view of the platencarriage and of a roll of paper, the spool whereon the paper is wound being shown in cross-section. At this figure is illustrated the position of the mechanism when a bill is being torn off from the roll. Fig. 7 shows an improved front paper-guide, and Fig. 8 shows the usual adjustable bracket upon which said guide is mounted. Fig. 9 is a longitudinal section of the spool whereon the paper is wound. Figs. 10 to 15, inclusive, show diagrammatically the successive steps in the operation of writing and removing a number of bills and producing carbon copies thereof upon a single record-sheet.

In the several views like parts are designated by like numerals of reference. Gertain portions of the machine are omitted or broken away, so as more clearly to disclose the invention.

1 designates a platen having a shaft 2, which isjournaled in the end bars 3 and 4 of a platen-frame, the front and rear bars whereof are designated, respectively, as 5 and 6. This frame is hinged at 7, Fig. 1, to arms or bars 8, projecting forwardly from a truck 9, which runs upon antifrictiomrollers'10, the latter rolling along a single grooved track 11, mounted upon a top plate or type-bar ring 12. The truck is prevented from tipping forwardly by means of a horizontal bar 13, which is carried by the rear ends of truckarms 1% and bears up against an antifriction-roll 15, mounted in a fixed bracket 16. Along the front portion of the platen-frame extends a guide and shift bar 17, which is engaged by antifriction-rolls 18, mounted in a bracket 19, attached to the front bar 5 of the platen-frame.

Pressure-rollers are mounted upon arms 21, depending from the rear bar of the platen-frame, to which they are hinged at 22, and springs 23 are each secured at one end to the platen-frame in the usual manner and bears at its opposite end on the rear side of an arm 21, near the lower end thereof, seat; to force the rollers against the platen, and hence enable them to coact with the platen to feed the paper in line-space direction. Each pressure-roller arm 21 is provided with a projection 24, which terminates just behind a releasing-tappet 25, carried by a rock-shaft 26, said shaft extending parallel with the platen and being journaled in lugs27, formed upon the under side of the end bars of the platenframe. (See Figs. 2, 5, and 6.) By rocking said shaft the tappets are caused to press the fingers 27, the arms 21, and the pressurerollers 20 away from the platen, thereby facilitating both the introduction of the paper between the rollers and the platen and the subsequent adjustment and withdrawal of the paper. Also arranged in rear of the platen is a curved sheet-metal paper guide or deflector 28, having earsatitsends,wherebyitishung upon pivot-screws 29, carried by the platen-frame. Forwardlyof the platen is arranged a curved guide-plate 30, carrying a pressure-roller 31 and pivoted at 32 upon ablock 33, which is adjustable along the front bar 5 of the platenframe. The plate is spring-pressed toward the platen and adapted to guide the leading edge of the sheet forwardly and upwardly as the paper feeds around the platen.

At Fig. 1 is illustrated a portion of a Gorin tabulator mechanism comprising a column stop-rack 34 and supporting-arms 35 therefor, said arms being secured upon the truck 9 by screws 36, and at Fig. 2 are also shown denomination-blades 37, levers 38 for operating the latter, and key-rods 39, connected to said levers. At Fig. 2 is further shown acarriage-rack 40, a pinion 41, meshing therewith, and an escapement-wheel 42, connected to the pinion.

The devices above described are all in common use upon said Remington No. 8 typewriting machine.

Upon the truck 9 we mount a rectangular spool-carrying frame, comprising upright end bars 43, upper horizontal bar 44, and lower horizontal bar 45, the latter being provided with short stems or feet 46, Fig. 5, which are adapted to enter perforated bosses 47, usually formed upon the truck 9 for receiving the supporting-stems of the paper-shelf. The bars 43 are provided with opposite pivotscrews 48, upon which is hung aspool,designated generally as 49 and comprising flanges 50 and a core 51, a web of paper 52 being wound upon the latter. Either screw 48 may be loosened sufficiently to permit removal of the spool. Each screw is provided with a lock-nut 53, having a handle, Fig. 2. The right-hand spool-flange 50 is fixed upon a short tube or bushing 54, Fig. 9, which fits snugly within the bore of the tubular core 51 of the spool and may be drawn out therefrom, so as to permitafresh roll of paper to be mounted upon the core 51. A friction-spring 55, Figs. 1 and 2, bears against the left-hand spool-flange, so as to'prevent excessive overthrow of the spool and roll when a length of paperis rapidly unrolled therefrom. Instead of feeding directly from the spool to the platen the web is led from the roll up over the bar 44 and thence down to the platen, so that the paper may always feed into the machine at the same angle whether the spool is full or nearly empty, thus avoiding any contact of the paper with protruding parts of the type-writer mechanism, such as would sometimes occur if the web were led directly from the spool to the platen, causing crumpling, mutilation, or smearing of the paper. At one or both ends of the spool-carrying frame is fixed a gage-finger 56, provided with aslot 57 and adjustably held in place by a screw 58 and washer 59. By means of the gage the operator may determine approximately how i far to advance the web in order to bring the division-line thereon to severing position.

To facilitate tearing off the bills, a blade 60 is arranged longitudinally of the platen, being carried upon the upper ends of pivoted arms 61, which are mounted upon brackets 62,arranged upon the front bar 5 of the platenframe. The blade stands norm ally forwardly of and higher than the platen and may be swung down against the latter. The arms 61 support the middle portion of the blade,whose length is about equal to the-length of the platen. The extremities of the blade are stiifened ,by means of struts 63, which extend obliquely to the lower portions of the arms 61. The latter are hinged upon screws 64, which are tapped into opposite lugs 65, the latter being secured upon the brackets 62 by means of screws 66, each lug having a slot 66 through which the screw 66 passes. The lugs may be independently adjusted forward or back when assembling the parts upon the machine, so as to bring the blade into parallelism with the platen. Each bracket 62 has a forked portion, which bestrides the front bar 5 of the platen-frame, and a screw 67 for clamping it to said bar.

At its left-hand end the blade is connected by a link 68 to the upper end of a crank 69, fixed {upon an end of the release-shaft 26, which projects beyond the platen-frame, the link overlying the left-hand bar 4 of said frame.

against the platen, the link 68 is simultaneously thrust rearwardly, so as to operate the crank 69, and thereby cause the release of the paper from the control of the pressure- When the blade is swung down rollers 20, thus enabling the web 52 to be drawn around the platen until a severing line or mark thereon is brought into register with the top edge of the blade. The movement of the blade and connected parts is limited by an adjustable screw 70, which is tapped into the link 68 and is adapted to contact with the left-hand bar 4 of the platenframe, as at Fig. 6. The blade is provided with an operating-knob or finger-piece 71. Also operated by the crank-arm 69 are two plates or fingers 72, arranged one at each end of the platen and at the rear side thereof and fixed at their lower ends in collars 73 upon the release-shaft 26, Fig. 3. Each of said plates extends inwardly at the terminal portion thereof, so as to overhang the platen, as at Fig. 1. Two opposing plates 74 are supported, by means of stems 75, feet 76, and screws 77, upon the roar bar 6 of the platenframe, the feet preferably being slotted to permit adjustment. The plates 74 also extend inwardly, so as to cooperate with the movable plates 72 to clamp ,both the recordsheet 78 and the carbon-sheet 79 so that the latter may not be pulled around the platen with the web 52 when the latter is being advanced, as aforesaid.

The pivoted front paper-guide 30 has a yokelike handle 80, which extends horizontally forward over the platen-frame, the guidecarrying block 33 lying within said yoke, as at Fig. 1. By means of said handle the guide may be conveniently moved toward or away from the platen, as required.

In operation the usual paper-table is removed from the machine and the paper-roll frame is placed in position, the stems 46 thereof being inserted in the carriage-lugs 47. The right-hand spool-flange 50 is withdrawn from the core 51 and the roll of printed paper is slipped upon the core, said flange being then restored to place and the spool being mounted upon the center screws 48, which are then duly adjusted to the spool and locked by the handle-nuts 53. The leading end of the web is passed over the deflector-bar 44 and down to the platen, passing behind the stationary clamping-plates 74 and between the platestandards 75 and is introduced between the platen and the deflector-plate 2S and is caught by the pressure-rollers 20. The platen is then rotated in the usual manner to advance the web until the first blank line thereon, upon which the name of the customer is to appear, reaches the bottom of the platen. At this time the leading edge of the web is opposite the blade 60, and in order that the paper may be straightened the blade is pushed down against the platen, and the edge of the web is adjustedinto register therewith. The movement of the blade is communicated through the link 68, crank 69, release-shaft 26, and tappets 25 to the arms 21, thereby causing a movement of the pressurerollers 20 away from the platen, as illustrated at Fig. 6, so that the web is released and the said adjustment thereof is facilitated. Having thus brought the web to the proper position for beginning the writing of the bill, the record-sheet 7 8-that is, the sheet upon which the carbon records are to bemade-is inserted between the web and the platen, together with the carbon-sheet 79, the pressure-rollers still being off the platen, as at Fig. 6. The web 52 may be slackened, so as not to obstruct the introduction of the carbon and record sheets between the web and the platen. The record and carbon sheets are advanced until their leading edges overlap the printing-line upon the platen. If desired, they may be advanced until even with the leading edge of the web, thus causing a blank space to be left at the top of the record-sheet, although we prefer to advance said sheets only far enough to slightly overlap the printingpoint, thus permitting a maximum number of entries upon each'record-sheet.

The carbon-sheet 79 and record-sheet 78 must, unlike the web, pass between the plates 74 and the opposing plates 72, as illustrated at Fig. 2, so as to be clamped thereby when it is desired to advance the web independently. As will be understood, however, from the foregoing description of the mechanism, when the pressure-rollers 20 are cast off said clamping-plates 72 are automatically brought into contact with the plates 74, thus for the time being preventing the introduction of said sheets between the clamping plates. Consequently said sheets are passed down in front of the plates 72, and as soon as the leading edges of the sheets have been advanced to a working position the severing-blade is lifted by the knob 71, thereby restoring the release shaft 26 to its normal position, permitting the pressure-rollers 20 to be moved against the paper by the springs 23 and also swinging the clamping-plates 72 forwardly to their normal open positions, so that the side edges of the paper may now be pressed or buckled inwardly and worked rearwardly around the ends of the plates, the sheets then opening out and lying within the open clamp, as illustrated at Fig. 2. If desired, however, the carbon and record sheets may be introduced together with the web, the leading edges of all three sheets coinciding and all passing behind the stationary clamping-plates 74 and being simultaneously adjusted to the edge of the blade, as described, the carbon and record sheets being subsequently worked around the ends of the plates 74 and brought within the clamp. All of the sheets having been adjusted, the writing of the name and address may proceed. Then the platen may be rotated, so as to bring into printing position the first blank line or space upon the body of the bill, whereupon the writing of the items may proceedin the usual manner,acarbon copy thereof beingproduced upon the record-sheet. At Fig. 6 a type-bar is indicated at A in printing position, and at Fig. 1 are shown the ratchetwheel B and the driving-pawl C of the usual IIO line-feeding mechanism. Upon the completion of the bill the knob 71 is operated to bring the edge of the blade against the paper, and by the same stroke the pressure-rollers are thrown off and the plates 72 are caused to clamp the carbon and record sheets against the plates 74. .The leading portion of the web is grasped by the operator and pulled up until its leading edge about reaches the adjustable gage 56, Fig. 12, thus bringing the bottom of the bill-head about opposite the blade, a corresponding length of the web paying off from the spool 49, and the

sheets

78 and 79 remaining stationary, as they are firmly held by the clamping-plates. Then the printed or perforated severing-line or other mark upon the web is more carefully adjusted into register with the edge of the blade. Then with one hand the operator may press the blade more firmly against the platen and with the other hand may tear off the bill.

It will be understood that by the last-described adjustment of the web the blank for the next bill is brought into position for receiving the first line of type impressions. The record-sheet, having remained stationary during the independent advance of the web around the platen, is likewise in position to receive the carbon impressions of the first line of writing upon the second bill. In order, however, that the second entry upon the record-sheet may not overlap the first entry thereon, the operator should be careful to feed all of the sheets one or more line-spaces after writing the last lines upon the first bill and before clamping the record and carbon sheets in the described manner, so that as soon as the first bill is torn off and the blade lifted the writing may proceed without further manipulation, asuitable space appearing between the two bills upon the record-sheet. In this manner the writing of the bills may proceed one after another until the recordsheet is full. It will be seen that while the record-sheet feeds in unison with the web during the line-spacing operations it is not drawn forwardly with the web when preparation is being made to tear off the bill from the latter, inasmuch as the clamp detains both the record-sheet and the carbon-sheet, and thus there is effected a great saving both in carbon and record paper, since while the writing of a dozen bills might consume five feet of paper from the web, still said bills would not occupy more than perhaps sixteen inches in length of record-paper. It will also be seen that at no time is the platen or the paper moved backwardly, but that there is a constant forward feed and that no special adjustment of the carbon or record sheets is necessary after they have been once inserted in the machine. It will also be understood that the space upon the record-sheet occupied by each bill or entry is dependent upon the number of items thereon, so that a bill containing but few items consumes only a small portion of the record-sheet,and if there should leasing the pressure-rollers until the division- L line upon the web is brought up to the severing position. By this operation the record and carbon sheets are advanced so far that they may be easily Withdrawn from the machine. Then the bill is torn off in the described manner, and before the writing of the next bill begins a fresh record-sheet is inserted, together with the same or a fresh carbon-sheet, whereupon the writing of the bills is continued.

Referring now to Figs. 10 to 15, inclusive, it will be seen at Fig. 10 that both the web and the superposed sheets are in position to begin the writing of the bill. The leading ends of the record and

carbon sheets

78 and 79 slightly overlap the printing-point, while the leading end of the web is carried upinto register With the blade 60, the portion of the bill-head which extends around the front of the platen being occupied by the printed matter. The first line of type impressions falls upon the unprinted record-sheet 78 at f. At Ct is indicated the dividing-line between the first and second bill-heads upon the web. Fig. 11 shows the positions of the several sheets at the completion of the writing of the first bill. It will be understood that the Written lines occupy the space between fand 9 upon the record-sheet. WVhile the record and carbon sheets are detained the leading end of the web is independently advanced until the first severing-line a thereon registers with the blade, as at Fig. 12, whereupon the bill is doubled over the blade, as indicated by the dotted line, and severed, thus leaving the top edge of the second bill in register with the blade, as at Fig. 13. Thus it will be seen that the first and second bills are advanced together and that the movement that brings the first bill into position for detachment also brings the second bill into position for beginning the writing thereon. The second bill is now written, the carbon duplicate thereof occupying the space between 9 and 71. upon the record sheet. Then the web is advanced independently until the second severing-line Z) thereon registers with the blade, whereupon the second bill is torn off, as at Fig. 1a, thus leaving the third bill-head in position for the writing to be begun thereon. The carbon impressions of the third bill fall between h and 2' upon the record-sheet. The web is then independently advanced until the third severing-line 0 thereon is even with the blade, Fig. 15, whereupon the third bill is torn off, leaving the fourth one in position for writing. The severing-line of the fourth bill is indicated at (Z and that of the fifth bill at (2, Fig. 15. it will be understood that atthe com pletion of the fourth bill the remaining space upon the record-sheet'is filled, whereupon without releas ng the pressureroller the platen is rotated, so as to advance the web until the severing-line (Z thereon is opposite the blade and simultaneously feed the record and carbon sheets out of the machine, whereupon a fresh record and carbon sheet may be inserted in the manner above set forth.

In case any bill should contain an excessive number of items, so that it could not be accommodated upon one of the blanks printed upon the web, the latter may be temporarily pulled out backwardly from the platen without disturbing the carbon and record sheets, the latter being held by the closed clamping plates, and a single long sheet having a heading printed thereon may be inserted in lieu of the web and duly adjusted. As soon as it is written and withdrawn, the carbon and record sheets of course being detained in the machine, the leading edge of the Web may be again introduced and the writing of the short bills proceed as before.

i using a printed web the necessity of introducing and adjusting a. separate printed sheet for each bill is avoided, and much time is thereby saved. If desired, however, the paper-roll mechanism may be omitted, and our other described improvements may be utilized to advanti'ige in writing upon ordinary detached bill-heads. It will be perceived that the gist of one portion of our invention resides in mechanically holding the carbon and record sheets in position for a new record while the written bill is being withdrawn from the machine.

It will be seen that we have combined devices for feeding superposed sheets of paper with means for mechanically detaining one or more of the sheets during an independent advance movement of the remaining sheet or sheets, said detaining means being preferably in the form of a clamp which may engage one or more of the sheets at will; that the clamp is normally open and the sheets 78 and '79 feed through said clamp and lie between the web and the platen; that the clamp is carried by the platen-frame and arranged at the receiving side of the platen or the side at which the paper feeds into the machine; that the opposing plates or ja s of the clamp overhang or are within the field of the platen; that the clamp is held open by a spring or springs 23, which actuate the arms 2t, and thereby press the tappets 25 forwardly, together with the rock-shaft 26 and its clamping-plates 72; that the clan'ips are adapted to hold the side edges of the paper, one of said clamps being arranged at each side of the paper or at each end of the platen; that the finger-piece 71 is connected to the clamp-shaft 26, which extends longitudinally of the platen; that the sheets 78 and 79 pass between the opposing members of the clamp while the sheet 52 passes outside of said opposing members, so that at the operation of the clamp the sheets '78 and 79, which are nearest the platen, are mechanically held stationary; that the paper-clamp is stationary, in the sense that it does not move around the platen, together with the paper; that the clamp is operatively connected to means for releasing the paper from the paper-feeding devices; that the clamp operates automatically to grip the side edges of the paper when the sheets are released from the pressureroller; that the pivoted arm or arms 61,which carry the severing-blade 60, may be regarded as a single lever and that the relation of said lever to the link 68 is such as to form a toggle,whereby the crank 69 is swung and looked, as at Fig. 6, thus leaving both hands of the operator free to adjust and tear oil": the Web 52; that a single stroke of said lover or toggle is su tlicient to operate and lock the crank and connected devices; that the severingblade is hinged upon the platen-frame and extends along said platen for substantially the entire length thereof; that the blade normally stands away from the platen and is movable into contact therewith, the extent of said movement being adjustably limited by the screw 70; that by means of the ing the blade is adjustable in a direction transverse to the platen, and that when the blade is moved to operative position the pressureroller is simultaneously cast off and the clamp closed.

Many changes may be made within the scope of the invention, portions of which may be used without others. Although we have described particularly the operation of recording bills, still it is obvious that the invention may also be used for making condensed records of all kinds.
