FRED E. MAIN, OF GHIC AGO, ILLINOIS, ASSIGNOR 0F ONE-TENTH TO UNDERWOOD. TYPEWBITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

TYPE-WRITERAND- CO PUTING-MAC INE To all whom it may concern:

Be it known that I, FRED F. MAIN, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented new and useful Improvements in Type-Writers and Computing-Machines, of whichthe following is a specification.

This invention relates to typewrlting ma*-' chines, and particularly to means for locat ing perforated sheets in the machine in position to be written'upon, and for'also feeding the sheets in line-space direction.

I am aware of an application filed by Lyman R. Roberts, December 23, 1909,. No.

534.57 9, to the overlapping subject-matter of which and the present application, I make no claim.

In the usual operation of typewriting, a

number of sheets may be placed in the ma-,

chine with their leading edges in register. The work-sheets with their carbons are imposed one upon another to form a sheaf, which is introduced into the machine; and after the writing is done,-all the sheets must beremoved in order to permit the top sheet,

usually a bill, to bewithdrawn and replaced by a fresh blank, whereupon the sheaf may 7 be replaced in the machine.

In bookkeeping and similar work, however, it is desired to retain in the machine a record sheet, that is, a sheet uponwhich are made successive records of the items written upon bills or other temporary work sheets which are written upon and then removed while the record sheet remains; the entries appearing in theirproper places on the bills, while the same entries appear one after another in proper sequence on the record or permanent sheet. In performing this class of work, it is desired to make sev- ,eral copies simultaneously, by means of carbons or ribbons, orvboth, upon two or more sheets; and it is also desired to'place the upper or outer temporary sheet or sheets I in the machine in position to insure that the .be superposed in difierentpositions 'in the typewriting shall fall in the properpositions on said sheets, as well'as in proper position beneath the last written line on the permanent or record sheet.-

In practis ng'my invention, the sheets will machine, usually with the sheets overlap-5 ping one another at their top, bottom and.

Specification of Letters Patent.

mined by a printing-line on said sheet; this printing-line being sometimes indicated by ruling, which is placed upon the work-sheet prior t0 beingwritten upon. Where difiers. ent kinds offorms are used, the ruled line of one sheet which is to receive a certain typewritten line, mayv be in an entirely different position from the ruled line on another sheet which is to receive the type-- written impressions at the same time; and

both of said ruled lines may be diflerently- I located from the printing-line on the record sheet which is in the machine. taken care of by perforating the work-sheets in their margins, and providing upon the type-writing machine adjacent to the revoluble platen a series of studs upon which the work-sheets may be positioned or gaged bymeans of their marginal perforations. These studs are preferably arranged along the right and left-hand sides of a worktable or Thisis all y support adjacent to the revoluble platen,, so that any sheet may be adjusted up or down 7 as required andwithout disturbing the ads justment of a sheet previously placed upon the studs. By this means not only are sheets properly placed in relation one to'another, so that the typewriting may fall upon the cilitate the assembly: of sheets ini their proper order and positions.

In using my invention, very many worksheets, all having various sizes and characteristics, may be equally and accurately brought into printing positions upon a rev o' luble platen in their required relationship to one another. 7

Another feature of my invention resides in the provision of means whereby not'only:

one but several, superimposed or'otherwise arranged record sheets may remain in the machine in proper'relationship to one an- 6 other and to the revoluble platen, while bills or temporary work sheets are succes- .sively inserted and withdrawn, so that the successive records may appear on all the record sheets. This is accomplished in such a wayv that the record sheets are permitted to have different characteristics .as to size,

etc.; and the several record sheets may cupy unlike positions. Any one-or more of Several sheets may, be removed from the machine while leaving another sheet properly retained in the machine, even if said undisturbed sheet may be a top sheet.

I arrange at what is usually termed the delivery side of the platen, a work support having a fiat surface for convenience in arranging the work sheets. This support preferably inclines from the platen up- Wardly and rearwardly, and may have anarea somewhat in excess of the' largest worksheet to be used. Any sheet when placed upon this support may'engage, by means of the perforations with which the sheet is first provided, projecting studs, of which there is an array preferably on each side of the work support.

The sheets maybe superposed in various relationships, with carbons between and the studs not only enable the sheets to be' placed in the proper relationship one to another, but also gage or position the sheets properly relatively to the printing line on the platen; the studs being connected to the platen for this purpose by being arranged upon one or more endless flexible bands running around the end portions of the platen and extending up along said work support, and then running over a roll and down to'the platen again. The bands may have any required length, and the work support may be of any required height or extent. The upper strands of the bands may lie upon the fiat surface of the work support. and position the sheets when they are laid upon said support, but they are also em parallel with the cylindrical platen, without further attention from the operator; and the usual-releasable pressure roll mechanism may be omitted.

i i It will be understood that when the sheets are assembled or collated on the said fiat surface, with the-sheet perforations engaging the line-spas studs in such a manner The studs not only serve to engage.

that the desired various ruled or printed lines on the several sheets are registered properly with one another, the platen may be re volved forwardly, and the sheets, which are connected to the platen by means of the endless bands', are carried around the idle roll, and down back of and beneath the platen, and up to proper position for receiving the upon the front of the platen.

In the accompanying drawing, the revoluble platen 2 is mounted on the carriage frame 1, and is rotatable by means of a line-space lever 3, which it will be seen has v The work sheets, which are of Various sizes are designated as 18, 19, 20, and each sheet has along a side margin perforations 20 to engage gaging, spacing and attach ing means shown in the form of projecting gage studs 12. By the term studs, I do not wish to limit myself to a specific'form, but desire to include equivalent forms of attaching or spacing means, or both. The studs enable the justifying or gaging of a number of difi'erent sheets with respect to each other and the lines thereof which will come to the printing point at the same time. The work sheets are laid one at a time upon a work su port 9, which is in the form of a fiat sur aced plate extending upwardly and rearwardly from the delivery side of the platen, that is, the side from which the sheets usually emerge from the machine; and said plate is supported by standards 8 which rise from the rear of the carriage; upper and lower brackets 8 connecting the plate 9 to the standards 8. Said studs may be carried by one of the flexible endless bands 4, 4, and the bands may run around the opposite ends of the platen 2, the latter having its ends reduced to receive the bands, so that the latter may lie flush with or not protruded above the printing surface ofthe platen, as shown, so that they may not foul with the edges of the work sheets.

These hands run over an idle roll 5 which is placed above and behind the work support 9; the roll'5 also having reduced ends to receive the bands.

As manystuds may be arranged upon the bands as desired, and they may be equally spaced, as shown, to match the perforations in the work sheet.

Proper relationship between the oppos site sides of the studs is assured by means of gears 6, fixed to the ends of a horizontal shaft 7, parallel with the roll 5 and. platen type impressions; the types usually striking i 2. These gears rotate in unison and mesh with the studs 12, whereby accurate relationship of the studs along one side to those memes along the other side of the work table is assur'ed; creeping of either band being prevented.

The work sheets or forms are assembled individually and independently on the linespacing studs 12 of the various ba'nds,in such a manner that each sheet shall present to the printing position such part. as is to receive the-type impressions. The writing is done in multiple, since carbon sheets, ribbons, or other duplicating means are assembled between the work sheets. The larger work sheet 18 maybe placed in position first, and may remaln permanently in the .wmachine'until it is filled with writing, which of course would consist of carbon impres-' sions of the typewriting on the superposed sheets 19, 20. The sheet 18 may have perforations only along its right-hand margin, whereby it may be held upon and gaged by means of the right-hand studs 12. The

sheets 19 and 20 ma have perforations only upon their left-han marglns. 20 may be a bill, andmay receive the primary nnpressions directly from the types of the type writer; and 19 may be a shipping order, or any other form upon which it is desired to enter the item in correspondence with the entry upon the bill or other individual sheet 20. Of course any desirednumber of sheets and blanks of any desired kinds may be employed simultaneously.

Any work sheet when laid upon the table 9, may engage by means' of its perforations the studs 12, at either one or both sides of the table 9, and'the projecting studs will cooperate with the perforations in the sheets to control the positions of the latter rela-' tively to the printing point or line on the platen 2. After'the sheets are assembled, a-

handle or crank 16 may be grasped to rotate a large gear wheel 14:, which is mounted upon a stud 15 projecting from a bracket 13, and meshes with a small pinion 17 which is fixed upon the end of the platen shaft, whereby the platen is rotated and the bands set in motion. The gear 14 being revolved in counterclockwise direction, the platen is rotated in line-spacing direction, and the studded bands carry the assembled sheets up around over the idle roll 5, and down behind the work support or table 9, and under the platen and around up in front of the same, to bring the sheets to the printing point, or toposition to receive the line of type lmpressions. By means of the large or movement-multiplying gear 14, the platen is caused to revolve rapidly, and the forms are quickly brought into position. If desired, the usual sheet-feeding mechanism may be retained, and sheets be carried by the studs between the platen and these usual feeding devices. However,'the studs alone 7 may be relied upon to advance the sheets around the platen line by line, and hence remains in the machine.

the ordinary sheet-feeding devices need not always 'be used. The sheets, it will be seen, come up in front ,of the platen in the usual way, into position to receive the first line of type impressions.

To guard against .the forms falling off from the studs as they descend behind the work table 9, there is provided a metal sheet or guard 10, whichv curves forwardly at its or more sheets may be removed while another sheet or sheets remain in the machine. For instance, the right-hand sheet 18, which is the bottom sheet, could be removed without disturbing either 19 or 20. Or top sheet 19 could be removed without disturbing 20 or 18. Or both 19 and 20 could be removed 7 without disturbing 18. The individual forms or accounts on the sheets 19, 20, may hence be removed while the record sheet 18 In some cases, a single item is written uponthe sheets 19 and 20, whereupon they are removed, and fresh blanks inserted, but at a lower point upon the table 9, so that subsequently the typewritten impressions made upon these fresh blanks will fall at a lower place on the record sheet 18 than the previously typed impressions. vidual sheets will receive individual lines of type impressions, which fall one below another upon the record sheet 18, although these type impressions all appear in the same place upon the individualsheets. Although the individual sheet may always These successive indi have writing on the same line, still the rec-- ord sheets will never have successive entries made on the same line. It is this necessity for unlike and irregular relationship! of. the different sheets at successive operations,

that makes it impracticable to assemble forms properly for this kind of work in the usual construction of revoluble-platen type- .writing machine.

When the typewriting of a line is completed, the platen may be rotated forwardly in the usual manner, and the forms may be all brought to assembling position, where the individual forms may be withdrawn and new forms inserted as required.

This device is especially adapted to be used in typewriting machines which are -used for writing on sheets that. are punched at certain places, Such sheets are used in bookkeeping, particularly with loose-leaf fof this will be placed the bill which is to be sent to the customer. Any other forms such as shipping order slips may also be positioned either in back or on top of the bill itself. Thus the sheet on which records a'rg1 to be kept lies next to the assembling ta e.

Ifthen said bill and loose leaf are carried by the belts 4 around the platen, it will be seen that when the bill is in position to be removed, the loose leaf of the journal will lie flat on the assembling surface and the bill form may be removed without disturbing the loose leaf. Then another bill form may beinserted without removing the loose leaf from the mechanism, and if the pins 12 areat line-space intervals, said second sheet may be rapidly inserted at any desired line space.

To put it in. another way,afte r one form has been written on and passed iv around the platen and -then removed, the

loose leaf lies in position on the assembling table in convenient-position to place another form'on the pins 12 over the loose leaf, and

. said pins forin a convenient means for 10'- eating said second form at such a number of line spaces from the carbon record of the first form as may be desired.

-' r 1 Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
