Application flied July 9, 1917. Serial Ito. 1%),3531.
State of Wisconsin, have invented certain new and useful Improvements in Machines 0 and Counting Paper Towcling and the like; and I do hereby declare that the following is a full, clear, and exact description thereof.
The present invention relates to certain new and useful improvements in machines for interfolding sheets of material such as toilet paper and paper toweling, particle larly of that type exemplified in an application filed by me August 19, 1916, Serial No. 115,773, allowed April 6, 1917.
In machines of this nature, the work material is usually fed to the machine from a pair of continuous rolls and the webs of these rolls are longitudinally cut or slit and transversely cut, but not entirely separated, to form the individual sheets, which are subsequently interfolded. There is a tendency of the paper to become slack as its passes over the body rolls and if this slack is allowed to accumulate wrinkles are soon formed in the paper which in time will clog the machine, but by using the ties connecting each individual sheet, the paper is stretched across the body rolls and through the guides when. the ties are broken which prevents clogging of any kind.
It is therefor primarily an object of the invention to provide a folding mechanism which is of relatively simple structure, and positive in its operation, to promote its eiiiciency particularly with respect to permitting actuation at arelatively high speed;
The present folding mechanism comprises a pair of opposed members mounted for pivotal oppositely oscillatory movements and it is now more particularly an object of the present invention to provide means for successively clamping spaced folded portions of the sheets against the outer faces of the members to procure a, positive creasing of the sheets whereby upon rotation of said members to dispose the bends of the sheets at their respective sides of the pile of folded sheets, the material at the sides of the bends will be disposed in a plane parallel to the necessity of pressing the folded sheets after their removal from the machine.
t is further an important object of the present invention to provide a counting mechanism, for marking the folds of the work material at predetermined intervals, which is of ertremelv s nplc construction and accurate it its operation.
It is still further an object of my invention to provide an endless belt conveyor for removing the folded worl; material from the machine which will be continuously operated step by step at the proper speed to correspond with the operation. of the machine.
lVith the above and other objects in view my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and particularly defined by the appended claims, it being understood that such cl: nges in the precise embodiment of the herein disclosed invention may be made come within the scope of the claims.
in the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof in which:
Figure 1 is a front elevational view of a sheet interfolding machine embodying the present invention.
Fig. 2 is an end elevational view thereof.
Fig. 3 is a view similar to Fig. 2 of the reversed end of the machine.
' Fig. 4 is a transverse sectional View taken on the line 4l of l ig. 1.

Fig. 8 is a partly diagrammatic view illustrating the operation of the folding device, and
Fig. 9 is a view part in section and part in elevation of the counter controlling mechanism, .aid view being taken on the plane indicated lay the line 99 of Fig. 2.
is longitudinally mounted a pair of shafts T Mill 6 carrying the body rolls 7 of the feeding and cuttin mechanism which are in engagement and between which the mutually overlapped sheets of material 8 pass downwardly to the folding mechanism.
As described in the aforementioned application, the work material, prior to its delivery to the folding mechanism, is cut or slit longitudinally and also out transversely but not separated entirely, that is.
small ties which are broken in the folding operation connect the-sheets. As aforementioned, the sheets of work material 8 are fed downwardly to the folding mechanism and guided in their passage by means of suitable guides 9.
Pairs of alined longitudinal stub shafts 10 are journaled in the ends of the body frame under the bed roll shafts G and the stub shafts at one end of the frame are projected outwardly thereof and carry crank arms 11 connected by pitmen 12 with relatively shorter crank arms 13 of a pair of longitudinal shafts 1 1 journaled in the frame outwardly of the stub shafts 10, whereby rotation of the shafts 1 1 will affect oscillatory movement of the pairs of stub shafts 10.
Carried on each pair of alined stub shafts 10 is a folding member comprising end plates 15 fixed on the stub shafts 10 and connected at adjacent peripheral portions by preferably transversely arcuate wall 16 at oneside edge of which is formed an inwardly extending wall 17, the other edge of the'arcuatewall 16 providing a limit of movement for finger 18having its outer end shaped to form a bending ledge 18 and its inner end pivoted at 19 to the wall 17 and having an expansible spring 20 normally urging said linger against the outer edge of said arcuate wall. The end portions 15 and the. wall 17 preferably form a single casting.
For clamping spaced portions of the continuous web of overlapped sheets alternately to the oscillatory folding members, a plate '21 is slidably mounted on the outer face of the. wall 17 by extending the ends of the plate through slots 22 in the heads 15, and the outer end of this plate is laterally directed toward the wall16 to form a cl amping lip 23 adapted to coact therewith, this lip being normally urged. for clamp ng engagement by series of cxpansible springs 24 disposed \in sockets formed transversely 1n the wall l'? and bearing at their outer ends against lateral lugs 25 at the inner side of the clamping plate.
The ends of "the clamping lips 23 are.
adapted to alternately each engage the bending' ledge18 of the opposite folding member to thus/clamp the pap'r therebetween and to provide a positive tuck or fold in the aper thus clamped, which fold is disposed etweengthe clamping lip 23 and its wall 16; Apair of arms 26 arerigidly mounted on the inner face of each head 15 and carry mirac e at their outer ends a longitudinal tuck blade 27.
The movement of the clamping plates is also procured independently of the clamping members and through the medium of the shafts 14 by cam disks 28 loosely mounted on the stub shafts 10 at the ends of the folding members and have their cam portions engageable with rollers 29 carried on the ends of the clamping plates. The cam disks 28 have pivoted thereto links 30 which have their other ends of annular shape to em,- brace cams 31 on the shafts 14:.
As is obvious, the bending ledge, 18' comes in contact with the opposite clamping lip before the same reaches its upper limit,and thereby stretches the paper before the opposite clamping lip releases the paper. Hence it will be seen that the bendingyledge has two duties to perform, that of bendin the paper or preparing it for the tucking blade and that of tensioning the paper to prevent the upper end of the sheet from dropping after the ties are broken. v
The travel of the face of wall 16 is greater when midway between the limits of its travel, and at that point the fold is held in the clamp and as it travels faster than. the paper passing over the roll 7, it breaks the ties connecting the individual sheets at a point about half way down the guides 9. The sheets are partedabout one inch at that point and when the next fold is male the.
ends of the sheets almost meet again caused by the decrease in travel of the wall 16 at its lower limit which allows the ends of the sheets to register properly with the fold.
Taking up now the operation of the folding mechanism, the folding members simultaneously and continuously pivotally oscillate each through approximately a quarter revolution, and the upper and lower limits of oscillation of the coacting bending ledges and clamping lips respectively lie substantially in the horizontal plane passing through the axis of oscillation of the fold ing members, the lower limit of oscillation of the clamping lip being consequently at the vertical plane passing through the axis of oscillation of the folding members, whereby the folds held by the clamping lips are disposed horizontallyi when released.
As the inner side of a clamping member oscillates upwardly, its clamping lip 23 will move into the recess of the bending ledge 18, to provide a definite bend in the web for proper coaction with the tucking blade 27, it being noted that this clamping action occurs immediately below the meetin edges 'of a pair of sheets. The tucking b ade 27 of other said operating member then moves downwardly between its correspondingly bending ledge and the wall 16 of the other drum to thus dispose the bend or fold of paper between the lip 23 and wall 16. The
mes es fold.
Oscillatory movement.- of the folding mem I bers then continues and as the fold earrying member reaches its limit of oscillation the fold of work material is released by ongagement of the clamping blade roller 29 with portions 32 of the cams. this movement. to releasing position occurring immediately prior to the movement of the clamping lip 23 of said blade past a corresponding side edge of an endless delivering belt or chain to be later described and which is disposed under the folding members for receiving the interfolded pile of sheets. The entire operation described is repeated alternately with respect tothe folding members. By reason of the pitman connection for procuring pivotal oscillation of the members, it is noted that speed of the folding members is reduced adjacent their limits of oscillatory movement, and thus the varying clamping and tucking operations are facilitated( I An important feature of the present ar rangement is that the successive folds of work material are clamped against the outer faces of the members, and thus in their movements to releasing position the material at the sides of the folds is disposed substantially horizontally to lie in its proper position on the pile of folded material. to
thus eliminate the possibility of crimping the material adjacent its portions gripped by the folding members when said work material is disposed on the pile.
To successively pack the folds of work material on the delivery means, a series of presser lingers 34 are disposed at each side of the folding mechanism, having their extremities ext-ending slightly beyond the. axis of shafts 10, and each series of lingers is carried on a shaft 35 to which is imparted oscillatory movement by means of a roller carrying arm 36 carried by said shaft and engageable with a cam 37 carried on the cor responding shaft 14, the shaft being urged by a suitable spring 38, connect ".5 the outer ends of lovers 39 having their inner ends secured toshafts 35, to a POSltlOd wherein the fingers 34 are held by the cam in pressing engagement with the folded work material and are raised only momentarily by the cam incidental to the releasing movements of the clamping plates, in their raised positions said fingers engaging in transverse slots 40 formed in the walls of the folding members and in said plates whereby to engage the upper faces of the folds o work material.
Returning now to the general construction of the machine, power is initially imparted thereto through one of the shafts l i, and gear wheels 41 and Q2 are mounted on the shafts it and the bed roil shafts 6 respectively, each pair of gears 41 and 42 being connected by an idler gear 43 Thus a continuous drive is provided across the machine and the shafts ilare rotated in dillerent dircctioi'is to procure opposite oscillatory movements of the folding inen'ibers.
The novel form of delivery means which I employ consists essentially in a series of chains or belts ll passing over sprocket; wheels or pulleys 45 mounted on shafts i6 journalcd in the body frame One of the shafts --l-(' has mounted thereon a ratchet wheel ltl which is adapted to be advanced step by step to procure the steadymovemcnt of the delivery belts or chains. The means for operating the ratchet wheel d6 consists in a lever l7 having its inner end loosely journaled to shaft it} and its outer end pivotally connected by means of a toggle link 48 having its outer endpivoted to a crank pin it) on the outer end of one of the shafts It). said lever l7 having a pivoted dog 50 carried thereby and engaging the teeth of the wheel ill to advance the same upon the rotation of shaft 10 as will be obvious.
A further important feature of this .invcnlion exists in the novel form of countin; means which I employ for marking the folds of the work material at predetermined intervals. This counting mechanism eonsists in marking lingers 51 which pass through openings in certain of the pressing lingers H and are adapted at the an an tinny to rum do or mark a fold of' l l v the work material while the same is being held between clamping lip '22-, and wall t as will be readily seen in Fig. ti.
lbc marking lingers 51 are each connected by means of a link 53 with an arm 5- having its inner cnd lixed to a shaft extending transversely across the body frame and cured to this shaft is an arcuate lever 56 ha ving its outer free end directed inwardly as at 57 and engaging the am faces 58 connected with a pair of ratchet wheels 59 and 59. To normally urge the end 57 of the lever till-against the cam faces 58. a spring (it) is employed drawing inwardly .on the arm (31 carried by shaft 55.
The ratchet wheel 59 is lifted upon a sleeve 6:2 journaled in one outer 'all of the body frame 5. near one corner thereof, and ratchet wheel 59' is mounted upon the outer end of a stub shaft 62 journaled in sleeve (32. the ends of shaft 62 projecting beyond sleeve (32. As best shown in Fig.0, one cam is fixed upon the inner end of sleeve or and the other cam is fixed upon the inner end of shaft 62 adjacent said other cam. and the cams 58 have their faces recessed as at 3 said recesses being adapted to alinc as hereinafter described.
Loosely journaled upon the sleeve ea, in
termediate gears 59 and 59, are members 64:
- and'65 juxtaposed ratchet wheels 59 and 59 respectively and having pivoted thereto suit able dogs 66 engaging the uppermost portion of the adjacent ratchet wheels. These members 64: and 65 have directed therefrom in opposite directions an arm 67 having ivoted thereto one end of levers 68 whic have their-other ends both'pivoted to a common crank pin 69. carried by one of the bedroll shafts 6. t
Thus it will be seen that by reason of the arms 67 extending in opposite directions, the ratchet wheels will be revolved in opposite directions, and the notchesor recesses 63 are'so arranged as to aline at predetermined intervals, asfor instance, after the completion of the folding of every seventyfive separate sheets.
When the recesses 63 are alined, the spring 60 will draw the end 57 of the lever 56 into said recesses which will move the marking finger 51 outwardly and mark the fold of material which is at that time clamped be tween clamping lip 23 and wall 16, as herein before descrf ed. It will be further understood that t e number of marking fingers 51 depend upon the number of sheets which are folded in one operation Thus it will be appreciated from the foregoing description taken in connection with the accompanying drawings, that I have provided a practical and simple machine for accomplishing the desired purposes. 1
