`SETH WHEELER, OF CASTLETON, NEVJ YORK.
`
`PAPER PACKAGE AND PEOCESS OE FOEEIING SAME.
`
`Application filed November 6, 1817.
`
`Serial No'. 200,512.
`
`To all w]:am 62‘may concern:
`Be it known that I SETH WHEELER, of
`Castleton, in the county of ixensselaer, and
`in the State of New York have invented a
`certain new and useful Improvement
`in
`Paper Packages and FroCesses OI Forming-
`Same, and do hereby declare that the Iollow—
`ing is a full clear, and exact description
`thereof.
`'
`My invention ielates to paper packages
`, and process oIIorming- same and has for its
`Obj ectto prOVide an interIolded paper pack:
`age from which sheets or units may be with—
`drawn one at a time.
`A Iurtheroobject OI my invention is to
`piovide a package in Which the sheets are
`so interIOlded that the Withdrawal Of a sheet
`Vill position a portion of tie following sheet
`so that it may be grasped. readily.
`A further objectofmy invention is to pro—
`vide a package in Which the portion of the
`sheet positioned IOI withdrawal will have
`more than a single thickness.
`11. further Obj ect of my invention is to pro—
`Wde a packageinWhich thesheets are fOIded
`so that the package will occupy only a por-
`tion of the actual length of the sheet
`A further object ofbmy inventionis to pro—
`vide a packag‘lein which the sheets a1e folded
`or interIOlded so that the height of the
`package on each edgeis the same.
`A Iuither Objectb of my invention is to
`provide a package the sheets of which may
`he interfolded with a minimum of time and
`number of operations.
`‘
`Other and further objects of my inven-
`tion Will be. apparent from the folloWing,
`description, and from the annexed drawings
`OI embodiments thereOIa in Which——
`Figure 1 is an edge view of a single sheet
`folded ready for interfolding with similarly
`folded sheets;

`'Ihe folding and interlfo ding OI sheetsin
`order to form a package from Which the
`sheets may be withdrawn one at a time has
`assumed
`large
`commercial
`proportions.
`Such packagesare used for example,in con—
`nection with the dispensing of toilet paper,
`and at the presenttime theause of such pack~
`ages in connection with the dispensing Of
`paper
`towels is increasing rapidly. The
`packages oi papei ordinarily are placed
`in dispensing cabinets with a suitable open-
`ing through which extends a portion of:
`sheet in position to be grasped so that the
`sheet may be Withdrawn It is desirable that
`the Withdrawing Of one sheet shall cause a
`portion of the following sheet to be drawn
`through the opening and in turn extend
`Irom the cabinet in position ready for grasp—
`ing.
`It also .is desirable that the cabinet.
`shall occupy as litt1e space as possible and
`that the sheets shall stack evenly to form an
`even package In order to accomplish these
`desired ends, it has been customary to fold
`andinterfold the sheets. The folding of the
`sheets enables them to be stackedin narrow
`packages and the interfolding of the sheets
`causes the Withdrawal of one sheet to drag
`with it a portion OI the following sheet.
`It
`is the purpose of my inventiontobprovide an
`improved Iolded and interfolded package of
`sheets having the characteristics above set
`forth but different II‘OIIIcany package here—
`to1ore known and having distinct advan—
`tages in the saving of timeCvand operationsin
`folding and interfolding.
`In the embodiment Of my invention illus-
`tratedin the drawings, each sheetis shown
`as folded tWice to form substantially equal
`leaves two of which are on opposite sides of
`a substantially equal middle leaf. A sheet
`thus folded thereIore occupies a length only
`approximately one third the actual length OI
`the entire sheet, and each sheet has a Iold
`on each edge.
`1When the sheets then are
`interfolde‘d the paCkage will occupy much
`less space than the full size of the sheet, and
`the sheets will stack evenly and form an even
`package.

`position for grasping. The edge may be
`doubled
`upon
`itself
`but preferably is
`doubled over the upper and middle leaves .
`of a succeeding sheet as illustrated in the
`drawings.
`An important advantage of my invention
`is the saving of folding cost. It will be seen
`that two portions of 2Beach sheet
`(sheet 3) 1
`am interfolded respectively with the te1-
`minal
`leaves of the two preceding sheets
`(1 and 2), obviously reducing the time re—
`quired to interfold a given number of sheets
`witha resultant proportionate increased out—
`put in the number of sheets folded in a
`given time
`Many modifications of my invention will
`be apparent to those skilled in the art with- '
`out departing ther'ef10m or from the scope
`of the claims, my invention not being limited
`to the embodiment chosen to‘illustrate the
`sa.,me but comprising sheets folded into sub-
`stantially three equal parts and interfolded
`to present a folded edge for Withdrawal and
`to reduce the time required to interfold.
`Having des01 ibed one embodiment of my
`invention what I claim and desiie to protect
`by Letters Patent is:
`1. A package of sheets or units each of
`which is’folded twice to form three sub—
`stantially equal
`leaves two of which are
`on opposite sides of a substantially equal
`middle leaf and interfolded so that the ini-
`tial and middle leavesof each sheet after the
`first sheet have three leaves of adjacent
`sheets therebetween
`2 A packaoe of sheets 01 units each Of
`whichis folded twice to form three substan-
`tially equal leaves two of which me on op—
`,posite sides of a substantially equal middle
`leaf and interfolded so that the initial and
`middle leaves of each sheet afterthe first
`sheet have two leaves of apreceding sheet
`and one leaf of a succeeding sheet therebe—
`‘ tween.
`3. A package of sheets 01 units each of
`whichis13folded twice to f01m three substan—
`tially equal. leaves two of which are on op~ »
`posite sides of a substantially equal middle ,
`leaf and interfolded so that the middle and
`115
`
`11 Figure2 sheet 1 andasucceeding sheet2
`are shown slightly removed from interfolded
`position so as to indicate clearly the manner
`in which they are interfolded. Sheet 1 is in-
`dicated'1n heavier lines than sheet 2 merely
`for clearness of illustration it being under-
`stood that all the sheets ordinarily will be of
`the same thickness. It will be noted that the
`middle and lower leaves of sheet 1 lie be—
`tween the upper and middle leaves of sheet2 .
`In Figure 3 sheets 1 and 2 are shown in
`the samebpartially interfolded position as in
`Figure 2, with a sheet 3 added and also
`shown as slightly withdrawn from inter-
`folded position. Sheet 3is indicatedin dot-
`anddash lines merely for clearness of illus-
`tratio11,it being understood that all
`the
`sheets ordinarily will be of the same thick—
`ness and siZe.
`It Will be noted that the
`middle and lower leaves of sheet 2 also lie
`between- the upper and middle leaves of sheet
`3 and that the uppper leaf of sheet 3 lies be-
`tween the lower leaf of sheet 1 and the
`middle leaf of sheet 2.
`‘
`By reference to Figure 4. which shows
`sheets 1. 2, 3 4, 5, 6, and 7 folded and inter-
`folded in accordance with one embodiment
`of my invention, it will be seen that the
`folded middle and lower
`leaves of each
`sheet lie between the upper and middle leaves
`of a succeeding sheet.
`It also will be seen
`that the upper leaf of each sheet after the
`second sheet lies between the middle leaf of
`the preceding sheet and the lower leaf of
`the preceding sheet one removed. Although
`this1s the preferred manner of interfolding
`it is obvious that the top fold of sheet 3
`(F1gure 3) could be inserted between the
`middle and lower folds 0f sheet 1 to form
`a package having some of the characteristics
`of that '11st described or that each sheet
`, could be folded With both leaves on the same
`side of the middle leaf and interfolded asa

`‘
`In Figures 1A, 2A, and 3“, sheets 1“, 2“ and
`3” are folded and interfolded similarly to
`sheets 1, 2, and 3 in Figures 1, 2, and 3.
`The bottom edge of each sheet, however,
`is doubled over as indicated by ieference

`a terminal leaf of each sheet and the top
`leaf of a succeeding sheet are between the
`initial and middle leaves of an intermediate
`sheet, the top leaf of said succeeding sheet
`being below the said middle and terminal
`leaves of a preceding sheet. '
`6. A package of sheets or units each of
`whichis folded twice to form three substan-
`tially equal leaves two of which are on op-

`leaf and interfoldecl so that two leaves of
`each sheet are interfolded respectively with

`leaf and interfolded so that the initial and
`middle leaves of each sheet after the first
`sheet embrace the terminal and middle leaves
`of a preceding sheet.
`8. A package of sheets or units each of
`which is folded twice to form three substan—
`tially equal leaves two of which are on op-
`posite sides Of a substantially equal middle
`leaf and interfolded so that the top leaf of
`each sheet after the first sheet lies over the
`middle leaf of a preceding sheet.
`9. A package of sheets or units each of
`which is folded twice to form three substan-
`tially equal leaves two of which are on op-
`posite sides of a substantially equal middle

`middle leaf of a preceding sheet and be-
`neath the bottom leaf of the preceding sheet
`one removed.
`
`10. The method of arranging sheets or
`units in interfolded‘piles which consists in
`folding substantially equal end leaves of
`each sheet one on each side ofa substan—
`tially equal center leaf to form three sub-
`stantially equal
`leaves and inserting over
`the middle and terminal leaves of each sheet
`the initial and middle leaves of a succeeding
`sheet.
`
`11. The method of arranging sheets or
`units in interfolded piles which consists in
`folding substantially equal end. leaves of
`each sheet one on each side of a substan-
`tially equal center leaf to form three sub—
`stantially equal
`leaves and inserting over
`the middle leaf of each sheet the initial leaf
`of a succeeding sheet.
`12. The method of arranging sheets or
`units in interfolded piles which consists in
`folding substantially equal end leaves of
`each sheet one on each side of a substantially
`equal center leaf to form three substantially
`equal leaves and inserting over the middle
`leaf of each sheet and under the terminal
`leaf of the preceding sheet the initial leaf
`of a succeeding sheet.
`13. A package of sheets or units each of
`which is folded thrice to form four leaves
`and interfolded so that the first and second
`leaves of each sheet after the first shall have
`therebetween leaves of the preceding sheet
`and one leaf of a succeeding sheet.
`In testimony that I claim the foregoing I
`have hereunto set my hand.
