To all 'whom it may concern:

Be itknown that l, CHARLEs M. HrLsEE, acitizen of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certainV new and useful 4Iniproverrients in Typewriting-'Machinea of which the followin is a specification.

gfhis invention relates to means for collating sheets'upon the platens oftypewriting machines, particularly the re'voluble platens Vof front-strike machines, although certain of the principal features of the invention are available also forflat-platen typewriters.

VHeretofore, in collatingsheets, as for example, in collating an invoice (or statement) upon a ledger sheet, it has been the practice to introduce the ledger sheet and advance it around the platen and register it, and then to hold it there during the operation of introducing thestatement sheet and passing it around the platen over the V'ledger sheet and into thev desired registration with said ledger sheet; and thereupon usually Aboth sheets are drawn backwardly as a unit by the rolls of the typewriter until the proper v line upon the-statement isin position to receive the .impressions of the types.

It has been the preferred practice in collating sheets in this manner, to provideV each sheet with a row of registering perforations, usually along each side border of the sheet, and to arrange upon the typewriting machine p ins or studs to be engaged by these perforations, for accurately collating the sheets; the studs and perforations being depended upon to bring the sheet-s into thel exact-desired register with each other, so that the typed lines will fall in their proper places upon :each of the collated sheets.

1t is found in practice ditlicult to locate the perforations with the required accuracy in manufacturing the sheets. Moreover, the perforation is an expense, and it necessitates making thesheet of greater width than would otherwise be required, thus adding to the cost. The statement orV invoice sheet L articularly has to be increased materially in width, so that its side perforations Vmay match those ofthe wide ledger sheet; and this is objectionable not only b vreas'ons of the expense, but `also becausefthe widened statement sheet covers up certain special'coluinns upon the ledger sheet 1n which it is intended to type gures and items which it vi"YPEWErrINfsf-imonline. f

in the machine, to permitthe use of narrow statement vor invoice or other temporary sheets, to avoid dependence upon sideperforations for securing the desired accuracy of registration 'of one vsheet relatively to another, and to simplify the construction and operation ofthe machine.

Other features and advantages will. hereinafter appear. i

In the accompanying drawings, Y

Figure 1 is a perspective front View of the carriage of an Underwood .front-strike typewriting machine, showing my improvements applied tlieretotin one. form. I

Fig. 2 is a sectional side elevation showing ledger, statementand carbon sheets in position to begin typing thereon.

Fig. 3 is a front elevation showing the sheets collated and ready for ythe typing operation.

In carrying out the invention, instead of first introducing and registering the ledger or -other innerV sheetl 10the invoice, statementor otherouter sheet llis introducedadjust the statement sheet to position for typing. the first line thereon, this collating' table having at its top a gage 18 for gaging the leading edge of the sheet, and also having, along Vpreferably one.side, a gage 14 for the side edgek ofsaid sheet. The sheet maiv be squared or trued by either gage, preferably by the top gage 13, which has ample length for this purpose. Other gaging andl Y squaring means may be remployed for the leading portion of the sheet.

- The statement or outer sheet 1'1 having thus been introduced and'squared'to print-e. ing position', with the body of the statefl mentextending between the 'platen and the vreleased bottoni feed rolls 15, is now held temporarily in position'without the aid of said bottom feed rolls 15, which must re-f in ain cast off during the introduction of both the statement sheet 11 and the ledger sheet v10. This temporary holdingy means comlte - passed down between Vthe platen andthe prises a pair offyielding fingers or clips .16, which are arranged upon said collating .table to catch` upon the face of the statement sheet, holdinggit against the front surface of the collatiiig board 12, alightpressurebef l ing suiiicient to retain the sheet; said clips having turned-up front ends for convenience in inserting the Vsheet thereundergthe clips lThe ledger or record sheet is then introduced at the back of' the platen, and

statement sheet` 11; the vcarbon sheet 17 having beeninserted atthe same operation asA the statement sheet. The ledger sheet 10 is thrust forwardly and upwardly around the platen, between the same and the carbon and Y statement sheets, andV passes up 'behind the collating table 12, a, passage for the sheet being left at 17'?L between the table 12-and platen 9. y'

The ledger sheet'lO is preferably squared by theaidofthevsides 18.v of a chute 19, which preferably is erected at the vrear or introductory lsideiof the platen, and continues at laaround the Vunderv sidetliereof and merges lat the Vdeli-very side of thev platen to be squared and guided accurately thereby.

The chute may. be omitted in some cases if desired. .Thechute may be supported means of'studs 22 projecting inwardly from Vthe frame 23 that carries the platen 9, or by other suitable supports, andthe plates forniing the rear sides or gages 18'inay merge at their lower `portions (Fig. 2) with the plates or gages 21 ,',said plates also serving tosupport the table 20.V Arms or-bridges 24 may extend inwardly from the upper edges of V*the gages or 'plates 2l, to form mounts toV support the front collating table12; or theV parts 211 may meet to form a bar towhich 12 may be fastened, V12 lbeing thus spaced from 20, Ato afford a sheets 10,

' -In passing upV in frontgof'thevplaten 9, the

Vledger sheet 10`comes under the control of apairjof special rolls 25, which run upon preferably the delivery `side of the platen. The ledgersheet is made of vgreater width than thestatement sheetll, partly for the purpose of affordingVv room totype figures thereon which it is notrdesired to have ap-V Vpe'arj upon the statement sheet, and partly for the purpose of enabling said rolls 25 to engage and` feed the ledger sheet. These rolls 25y may be raised toopen a path for Y the upward passage of the leading edge of Y the Vledger sheet-:g5 being for' this purpose yielding 'to the edgewise thrust -of vthe sheet.

passageway for the j the month; Vthe corresponding entries 'of course, made upon/the ledgersheet. vln

mounted upon arms 25a, fixed at their upper ends upon a rock-shaft 251 mounted in standards 25c erected uponfthe-opposite studs 22. Double-acting springs'25d, engagf Ving said arms 25a, may hold the rolls either against the platen 9 or in an elevated position. These rolls are sufficiently separated to escape the statement sheet 11, Fig. 1, soV

that the ledger sheet may; be advanced or retracted by means of rolls 25 and platen 9,-

while the statement sheet 11. (witlicarbon 17) remains stationary, so thatthe desired relative positioning ofthe two 'sheets may be secured by'adjusting the undersheet 10.

After the ledger sheet 10 has reached a position between. its rolls 25 and the platen, the usual platen knob 26 may be grasped to rotate the platen, and thereby feed up the ledger sheet by the aid of said rolls; the feed rolls 15 which run upon the bottom of the Vpoint of the typewriting machine, or, in

other words, will lie exactly beneath or in register with Vthe line` upon the statement sheet which 1s ,to be typed. As an aid` the operator may lposition the ledger sheet by.

reference to the front wing scales 27 usually provided upon said Underwood machine to indicate the writing line. Y The operator can readily see portions of the lines 28 previously typed upon the ledger sheet,and hence can readily adjust said sheet sothat the next line of typing will fall in its proper place. This brings the ledger sheet into proper register with therstatenient4 .11, whose position lwith reference to the printing point has been mechanically determined .'by the gage 13. v v l The operator then restores the bottom feed rolls 15, so as to hold the sheets smoothly against the platen. Said rolls may also ef fect the line-feeding ofV the statement and ledger sheet jointly if. required; and in such case, the operator may withdrawtlie statement sheet from beneath the clips 16, so that If the same statement and ledger sheet are desired to be re-introduced into'the machine upon a subsequent day, to'have another item venteredthereon, the operator may introduce the sheets as before, and may then, by means ofthe platen knob, advance them as a unit a distance equal to one or two lines, to bring them to Vproper position to receive the new item, which it is desired to type at a point just below the item last entered, as afore-r said. In this way, the statement may he filled up'from'day to day until theend Vof being,

the next month the same ledger sheet may be used with a fresh statement; he ledger sheet being, however, advanced far enough by the pla-ten lt-nob 26 to bring` the succeeding months entries below those last made upon the` ledger sheet. The bottom feed rolls l5 are useful both when more han a ingleline is to be typed upon the statement, and also when it is desired to adjust the sheets up or down after introduction, and before typing the lirst line.

It will be seen that the invoice sheet is readily introduced and brought to its printing position with Vunfailing accuracy, and that it is only necessary to insert the leading edge of the invoice sheet under the clips, which can be done by merely thrusting the sheet up under them, as they have very light tension and yield readily to the insertion of the sheet between the saine and the table.

it will further be seen that it is unnecessary to collate one sheet over another one which has previously been placed in the machine, and which it would not be convenient. to retain in position without the use of registering pins, or the like, ranged along the side borders of the sheet. It will be understood t-hat the ledger sheet slips readily around the platen between the same and the previously-inserted statement or invoice sheet, which is held upon its collating table, orbetween the platen and the carbon sheet which was introduced into the machine at the same time as the invoice sheet; the lower feed rolls being cast ol3 during the introduction of both sheets, so that there is left open a passage for the ledger sheet between the platen and the other sheets. if desired, the statement, carbon and ledger sheet may be droppedL into the machine at the same time, with the statement in advance of the ledger sheet, and the sheets thrust forward and up in front of the platen, the, statement being conducted up in` front of table l2 and adjusted and clipped while the ledger sheet remains unadjustec, and said ledger sheet being then thrust forwardly under the rolls 25 and set to position in the manner already explained. Y

It will also be seen that the statement sheet, when thus mechanically brought to exact printing position, may serve as a guide for locating the ledger sheet in rear thereof, since enough of the ledger sheet can be seen at the sides of the invoice sheet-to enable one sheet to be brought into the desired longitudinal register wit the other; or the usual winescale in front of the platen may be relied upon, as explained, for positioning the ledger sheet accurately up or down. `When the sheets have once been introduced and brought int-o the desired registration with each other, the typing- 'iiay proceed without further manipulation ofeither sheet, and it is not necessary to withdraw the invoice sheet from the clips unless the typing is to malte more than one line upon the sheet. lt is rendered unnecessary to keep track of the engagement of pins with perforations along the sides of the sheets, and to see that the paper is properly withdrawn from the pins at numerous points at each side of the sheet, as heretofore. The statement sheet needs to be of no greater than normal width, and the ledger sheet may be made of as great width as may be desired, without being confronted with the necessity of increasing the width of the statement sheet to the same extent. EX-

pense is saved in manufacturing the statement sheet because of this saving in width; and it is no longer necessary to perforate additional side lines down the statement sheet to enable the waste margins to be torn off; and the statement sheets as sent out to the customer have clean-cut edges instead of rough edges. rlhe operator is enabled to See a large part of the ledger sheet, which is an advantage to be appreciated, since heretofore all or the principal portion of the typing lield in the ledger sheet has been covered up by the widened statement sheet. Moreover, the accuracy of collation of the sheets does not depend upon perforations in their side margins, which are apt to be inaccurately made, but they depend merely upon the operator advancing :the ledger sheet singly to a position to bring the writing line thereon into register with the usual scale, which is an operation readily performed with accuracy. Other advantages will be clear from the drawings and specilication.

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