Definitions

  • 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.
  • Figure 1 is a perspective front View of the carriage of an Underwood .front-strike typewriting machine, showing my improvements applied tlieretotin one. form.
  • 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.
  • statementor otherouter sheet llis introducedadjust the statement sheet to position for typing.
  • 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.
  • 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
  • the ledger sheet'lO is preferably squared by theaidofthevsides 18.v of a chute 19, which preferably is erected at theêtr 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,
  • 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.
  • 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
  • the ledger sheet may; be advanced or retracted by means of rolls 25 and platen 9,-
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a typewriter the combination with a platen, of means for holding a work-sheet in predetermined relation Vtherewith for typing, said holding means comprising a paper-table at the delivery side of said platen, an end gage for said sheet, and a clip, the relation between said table, gage and clip being such that the clip will be rendered elllectiife by the advancement of theV leading edge of said sheet along said table into gaging relation with said gage.
  • collating board and mount Vopposite gages for the side edges of the inner sheet at the delivery side of the platen and in rear of said collating-beard, for controlling the inner sheet, 'means to support said side-gages.
