Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed July 9, 1919 serialvlio. 309,711.

To all whom it may concern:

Be it known that I, Hnmzvr S. LASHER, a citizen of the. United States, residing in the borough of the Bronx, in the county of the Bronx, city and State of New York, have invented certain new and useful Improvements in Typewriting Machines,of which the following is a Specification.

way by employing a machine of the type illustrated in the Wernery & Smith Patent, No. 1,132,055, in which the revoluble platen is displaceable upwardly for convenience-in manipulating the sheets, and in which the carbons may be shifted back from time to time relatively to the web or webs upon which the condensed records are to be made.

ends of one or more webs or plies (which may be either separate or in fan-fold form) are led around the platen and adjusted j .up in front thereof, and the leading edges are caught by a clip provided upon a carrier which is used to advance the webs as the and-connected to the'blades of the carboncarrier, as set forth in said patent. The outside sheet, which may be a ledger sheet, is

now introduced-t0 occupy a position upon the platen in front of the webs, so that the ribbon copy will be typed upon the ledger-sheet while the web or webs willbear the carbon type impressions. The carbon sheet, that lies between the ledger sheet and the lower sheet of the web, is advantageously caught by the clip together with the front edges ofthe web.

Inorderto introduce the ledger-sheet, the

platen is shifted up in themanner-set forth in said patent, and the web is introduced horizontally, bottom edge first, back. between the .front of the platen'and a guiding apron which may be the usual "knife and therefore stands a little in front of the platen. When the platen has been displaced, as aforesaid, it overlies the apron or guide so that'the rear or bottom edge of the In carrying out the invention, the leading sheet may be very readily inserted between the knife and the (platen. The ledger-sheet may be then shove backwardly to about the position for typing a line thereon and accurately positioned vby a back scale. Then the platen may be dropped or restored to its printing ROSltlOIl, and, if necessary, the leading edge of the ledger-sheet may be adjusted toa scale which extends vertically or inclined backwardly from the delivery side of the platen. The scales are numbered 2:. intervals to agree with the intervals of the horizontallines ruled upon the ledger-sheet. If the typing is tobe done upon line 1 of the sheet, then the leading edge of the sheet is adjusted to the figure l? on the scale, and so on; the lines upon the sheet being preferably numbered from top to bottom of the sheet, while the scale is numbered from bottom to top thereof, correspondingly. Dur- 1ng this final adjustment of the ledger-sheet totyping position, if there are bottom feedrolls and casting ofi' means therefor, they may be cast oil from the platen, or the adustment may be effected 'just before the platen reaches its printing position and while it is still separated a little from th feed-rolls.

The operator then types the line upon the ledger-sheetand carbon copies thereof are pr l))duced upon the nlv or plies of recordwe At the completion of .a line of writing, the

operator rotates the platen by means of the usual line-space handle, at the same time returning the platen or carriage to position to begin a new line. Since it is often the practice to make only a single line entry upon the ledger-sheet, the line-spacing mechanism may be regulated 'so that the platen is advanced two line-spaces at the return of the 'carriagee This produces a blank line between the entries upon the 'condensed record-sheets or webs.

After thus line-spacing the sheets, the operator advances the carrier to which the leading edges of the webs are clipped. This carrier may be mounted upon a track, which extends upwardly and rearwardly from the delivery side of the platen parallel with the 'scale aforementioned. The track may have notches at intervals equal tothe line-spacing movements of the platen to detain the carrier at the proper point in each instance. In

. some forms of the device the carrier may be automatically advanced, as by the line-space mechanism. 7

The item being thus typed and thelinespacing being thus attended to the next step may be to replace the typed ledger-sheet by a second ledger-sheet, In performing this operation,.the platen may be first displaced v upwardly :to bring all the sheets to horizontal condition, as in said patent, and then the second sheet is introduced while the first remains in the machine. The second sheet is thrust backwardly, bottom" edge first, advantageously between the first record-sheet and the platen so that the first sheet forms an apron for guiding the second sheet into the machine, this being a great convenience. Thereupon, the operator retains the second sheet in the machine :while he withdraws the first sheet which is then ready for restora .tion to the ledger. The second sheet is then manipulated in the manner already described respecting the first sheet, that. is, the platen is swung downwardly and the second sheet is adjusted to the point 1, 2, 3, or whatever it might be upon the scale corresponding with the line upon which the typing is to be doneon the record sheet.

The p'ly or plies of web are preferably provided with transverse perforations at suitable intervals, say of 10, 12,.or 14 inches, as may be desired, so that after one of these lengths of web is filled with typed copies of the record orled'ger-sheet, it may be readily torn off from, the web. Before this is'done, however, the carbon-carrier is thrust back to withdraw the carbons from the typed portion of thewebs, so that they will not be torn off, and to bring them into position for use with the next section of the web, this operation being explained in said patent. Thus, the operation of making condensed records upon sheets of uniform size may proceed unhas been advanced by the platen and before.

the clip has been advanced to holdit stretched out.

In the Underwood continuous fan-fold billing machine, as machines of the general type of the'Wernery & Smith patent are frequently called, the typewriter carriage 1 travels upon rails'2, being drawn along by a spring barrel, not shown, at each act ation of a type-bar 3, said type-bars controlling the usual escapement mechanism, not shown. A- web or webs 4 are drawn from the rear over'the usual rear rod 5 and pass downwardly over a paper table 6 beneath a platen 7 and up in front of the platen, so 'that-the type-bars 3 may print "thereon at the usual printing line.

In said machines, the platen is journaled byit's a Xle 8 in a swing frame 9, so as to carry it upwardly and forwardly away from the usual front and rear feed-rolls 10 and 11 into the'F'igu're 9 position, in which position the webs 4 may be drawn forwardly,

substantially straight, with the result that they may slip over-the usual carbon sheets is 12, which are clipped onto the usual carbon paper carriage 13. For holding the carbon, sheets, the carbon carriage 13 comprises side pieces'14 from which project in- 'wardly clip barsr15 alternately on opposite sides of the carriage, so that a carbon sheet 12 clipped to one of said bars may lie between every fold of a fan-folded web, The side pieces 14. of the carriage 13 are mount- IQB ed upona bottom plate 16, which is usually adapted to be removedfrom the body of the carriage, said body including. a mounting 17 .for rolls 18 by which the carriage runs upon the side rails 19. The side rails 19 are rigidly attached to the typewriter carriage l-by means of brackets 20, and extend rearwardly to the cross-piece or rod 5, and each rail has depending therefrom an ear 21, on which is journaled a roll 22-, which travels upon the usual rail 23 which serves to support the rear end of the rails 19. Normally,

' the platen, as has been stated, lies against the feed rolls 10 andll, and it is adapted to be locked down in that position by means of hooks 24, which are fast upon a shaft 25 and hook over rolls or ears 26 upon the swing frame 9; In Figure 14 the hook and car are shown outside of the swing frame, to avoid interference with other parts described below.

When the typist desires to insert a sheet, in the manner illustrated in Figure 9, the typist presses rearwardly a finger-piece 27 forming an extension of one of the hooks 24, thus releasing the swing frame, and then the typist swings the swing frame forwardly, usually bygrasping the upper front paper table 28 or'some extension thereof.

When the swing frame reaches the Figure 91 position, it is supported by means of bumpers, not'shown, thus leaving the hands of the typist free to manipulate the work-sheets. The device of the present invention is especially adapted to enable loose work-sheets to be used in connection with continuous webs 4, which may be fan-folded or not, as desired. 1 When the web or webs 4 and carbon sheets 12 are all ready in the machine and have been written on bythe types 3, receiving the impressions thereof through the carbon sheets 12, the typist withdraws the old loose work-sheet 29 already in the machine after inserting the new work-sheet.

To conveniently accomplish this, the old work-sheet 29 is allowed to remain in the machine while a new work-sheet 30 is being inserted, and the newwork-sheet is inserted between the old work-sheet 29 and the outside carbon sheet 31 of the sheets 12 on the carbon carriage 14. The outside carbon sheet '31, together with the other carbon sheets and the web sheets, is advantageously held by a clip 32 adjustable upon an extension or support 33 of the-paper tab1e 28.'

Thus, the work-sheet 30 when insertedand pushed rearwardly is unableto drag the out side carbon 31 rearwardly with it. Each new and old work- sheet 29 and 30 is usually in the form of a record sheet having a body 34, which may or may not be provided with suitable rulings, said record sheet also'having an extension 35 at its bottom to serve 7 for binding purposes. Where sheets of this character'areused, the old work-sheet 29, even when its last line has been written upon, will -lie in the position shown in Figure'9 at the time it is to be removed, its lower extension 35 lying upon or extending behind a guide 36 which forms the top of-the paper table 37. This being the case, the oldwork-sheet 29 guides the new work-sheet 30 up over the guide 36 and backwardly over it as far as the purposes of the work in hand may require, said new work-sheet curving, asit may happen to, downwardly beneath the carbon paper carriage 13, or resting on intermediate rods thereof, not shown. There is little tendency for the work-sheet 29 or for the webs 4 to sag between the guide 36 and the clip 32 since both'pass between a knife 38 and the platen 7,,said knife forming part of the usualswing frame 9; -When a new work-sheet has been inserted in this way, it may be aligned by means of a scale 39 upon the back of an extension 40, which may be provided according to my invention. If the head of the new work-sheet30 is so short that its upper end is concealed by the webs 4 when the first writing line reaches substantially its proper position, it may be inserted to any convenient position by the typist, and then the swing frame 9 may be swung towardits Figure 1 position, but not in contact with its feed-rolls 10 and 11, thus permitting the new work-sheet 30 to -be accurately aligned, since it then is adjacent a scale 41 upon the extension 40, and may have its side held against the turned-up edge 42 of the extension 40. When so positioned and held, the sheet is properly aligned, and the carriage and the swing frame 9 may be then swung rearwardly to clamp the worksheets and webs in position by bringing the platen against the feed rolls 10 and .11. The writing may then proceed in the usual manner.

The entries in the workforwhich this type of machine is especially adapted very often consist of only a single line apiece. If this isthe case, the typist actuates the usual line-space lever 43 at the end of a line. thus carrying rearwardly the line-space pawl 44,

to turn a double line-space the usual line space wheel 45, which, in machines of the continuous fan-foldbilling type, is fast to meshes with the pinion-48 fast to the axle- 8 of the platen 7 When the line-space leverhas been-actuated in this way, the web and associated carbon sheets will appear as in Figure 3, bending into a bight or loop 50,=

the lo'oseness of which will vary with the advance of the platen by the line-space lever,

which is adapted to variably turn the platen according to'the setting ofthe usual lever 49.

Before removing from the machine the sheet written on, which is-wnow the sheet 29, the typist slips the clip 32 upwardly along its support 33 a distance of a double linespace, i. e.', the amount the platen has been turned, this serving to'separate the item just written clearly from the item to follow. To do this conveniently, the clip 32 comprises a sliding body 51 having ears 52 in which is mounted a pawl 53, whose nose 54 1s adapted to catch in the depressions of a rack 55 cut upon the back of the slide or extension 33, said rack advantageously being in the form of shallow teeth out out of the plain surface -'of the extension 33. The typist will almost automaticfilly reach up and slip the clip 32 along a couple ofteeth to take up theslack of the bight 50, so that the webs then lie in the Figure 5 position. Then the typist releases the swing frame and swingsthe-platen to the Figure 9 position a to insert a new work-sheet, as described above. ,In inserting the new work-sheet, the typist merely notices the number in the column 56 of the line next to be written on, and ininserting the'new work-sheet brings the leading edge of the sheet to the scale line correspondingly numbered upon the extension 40. I

When writing upon the sheets in the Figure 1 position, they lie not onlyupon the extension at the left-hand edge vof the front paper table 28, but also upon an extension 57 springing from the right-hand edge of the paper table 28, said extension. 57 being also provided with a turned-up edge 58 to enable the webs to have their sides gaged thereagainst. The webs also lieupon the extension or support 33, and to steady the supports, there is provided a cross-piece 59 which underlies the extensions 40 and 57,

and is fast to them and to theextension 33 in any suitable manner; The extensions 33, 57 and 40 may be detachably held to the mounting of the paper table 28 by thumb screws 59*.

It will beobserved, especiallyfrom Figures'7 and 9, that the clip32 with its body mounting 51 is ofconsiderable length. To enable it to slide down onto the paper table 28, the extension :33 may be in the. form of a T having a body 6.0- which rests upon the bottom of a'hollow 61 in the paper table 28, said hollow being large enough to permit the body 51 of the cliptoextend as far down'as is necessary to seize the leading end of the webs .and carbon sheet when writing upon the first line-thereof below the usualLhealing. To enable the clip 32-to seize the work-'3 sheets firmly, it comprises a. cross-piece 62" adapted to he upon theface of the extension.

33, and it also comprises side pieces63 having rabbets 64: adapted to slide along and catch under the edges of theextension 33. Thecross-piece 62 may be hatched upon its surface. ,To hold the sheets against the hatched surface, a hatched jaw 65 maybe provided with ears 66 adapted to lie close to.

ears 67 projecting upwardly from the sidepieces'63, so that a pivot bar 68will hold the jaw 65 in proper positiontoibe swung to and from the cross-bar or piece 62. The jaw 65 is provided with a rearwardly extending tail 69, which is stifi though resilient, and which bears against a cam 70 fast upon a "accurately align the weband carbon the jaw 65 may comprise cars 74 adapted to serve as a leadin edge gage for them.

To permit the typist to shift'the clip 32 easily along the extension 33, the pawl 53 has an extension 74 forming a fingeriece for manipulating the pawl, and for shifting the clip 32 up and down the extension .33.

When a suitable length of webs. has been filled up "with entries, thislength may be severed from the bodyby drawing itagainst theknife 38, the webs being advantageously perforated at suitable regular intervals, as at 75'}, in, order to indicatethe point at which the severing should take place. This is especially advantageous in certain kinds of work,

because the detached sections of web are often used as thesheets of stock-ledgers or other ledgers, and for this purpose are bound 11p .inuleaves of uniform size. The length of the extensions 33, 40 a'nd 57 required will depend upon the len h of the web-sheetto be detached. Usual y the heading of the portion of the web to be detached is left blank because it is printed with a title, etc, and for this reasonthe extension 33 need not brin the clip 32 down to the knife38.

. en a section of web has been completely filled up, the1 typistreleases the clip 32 by. rotatin the crank 7 2, and then usually swings the p aten upwardly to the Figure 9 position, thus permitting the carbon carriage to be pushed rearwardly by the usual handle 75 to carry the carbon sheets behind the edge oftheknife, the webs being held in themeantimeby the typists finger or thumb. Then the typist swings the platenback to, writing position, after havin drawn the webs forwardly if need be, ah thensevers the desired portion. Next the typist clips the new ends of the webs and the carbon "sheets, including the outer carbon sheet, in

the clip 32, and before.

In the form of the invention shown in Figure 10,-the typist need not advance the we s bypushing upon the' clip 32. To avoid the need for doing this, there is shown the writing proceeds as a device for automatically advancing the.

webs between entries. To enable the machine illustrated in Figure 10 to be used for makin otherthan single-line entries, the web a vancing is illustrated as being actuated by theline-space mechanism. In effecting this, the extension 33 may "or may not be provided with the raclr, and the clip 32, which slides thereon, may be drawn by a cord 7 6 which passes around a pulley 77 at the top of the extension, so that the stretch of cord pulling on the clip 32 lies'along the center of 'the extension. From this point the cord 76 may be carried around a pulley '78 journaled in andguarded by an ear or loop 79, and be carried downwardly near the extension 40 to a reel 80 journaled upon the hub 81 of the pinion 47, said'reel having a diameter equal to or a very little larger than the pitch diameter of thepinion 47, thereby advancing the clip 32 amounts equal to the line-spacing advance of the work-sheets by the platen. In order to make the reel 80 tend to turn with the pinion 47', there is provided a friction clutch between the two com- .prising a friction washer 82 lying against the body'of the pinion 47, and the reel 80 has its face 83 pressed against the washer by means of a spring 84, which is held in place bya nut 85 screwed onto the hub 81. In order to guide the long stretch of the cord 7 6 along the extension 40, there may be provided a guide pulley 86 journaled in an ear 87 fast on said extension.

It will be observed that in every line-spacing operation the clip 32 will advance with the web advancing around the platen, and

. that when it is desired to draw the clip 32 down to the bottom to attach it to. a new end of the web, the reel 80 will slip to permit this, and upon subsequent line-spacing will proceed to wind up the web.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my. in'vention,--I claim: j 1.- In a typewriting machine, the combination with a traveling carriage and a revoluble platen, of feed rolls, a frame. in which said platen is adapted to be swung up clear of said feed rolls to permit plies of web and carbonsheets to be straightened out beneath the platen, and a clip above the platen to hold the-web plies and an outside; carbon sheet .while' awork-sheet is beingv inserted in front thereof.
