PAPER TOWEL AND TISSUE MACHINE.
Specification of Letters Patent.
Application led October 2, 1915. Serial No. 53,726.
To all whom 'it may concern.'
Be it known that we, HORACE P. BROWN and CLARENCE L. JOHNSTON, citizens of the United States, residing at Oakland, in the county of Alameda and State of'California, have invented new and useful Improvements in Paper Towel and Tissue Machines, of which the following is a specification.
This invention relates to means for cutting, folding and interleaving paper towels and tissue; and has for its object to simplify and improve the construction and operation of such means, and facilitate the delivery of the folded material from the machine.
In carrying out this object, we employ, in connection with improved cutting, folding and interleaving devices, which are of the general type disclosed and claimed in our co-pending application No. 806,732, filed December 15, 1918, a series of stripper fingers operable to remove the folded paper from each cylinder as soon as released by the folding jaws thereon; a tumbler' bar coacting with each series of stripper lingers to turn the folded paper in regular order away from the cylinder and direct it upon trave!- ing belts, whichbelts carry the material in interleaved stacks to a receiving bench, from Which an attendant may remove same for bundling and wrapping, and means, in connection with the machine, for printing at regularly spaced intervals al mark upon the paper as it is fed in a continuous web to-the folding cylinders, in such a position that the mark will appear upon the exposed edge of certain of the folded papers to indicate to the attendant the quantity delivered.
One form which our invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which-'- l l Figure l shows a side elevation of a ma.- chine embodying our invention.I
Fig. 2 shows a sectional View of the same taken on the line 2 2 of Fig. 3.
Fig. 3 shows an end elevation of the machine shown in Fig. 1.
Figs. 4 and 5 show diagrammatic views of the machine, taken on the lines 4-5 of Fig. 3, and illustrating different positions of the mechanism therein.
Referring now in detail to the form of our invention illustrated, it will be, Seen that the machine comprises, generally, a frame A carrying coperative folding and interleaving cylinders 10 and 11, arranged in pairs,
'each being provided with diamehrically Op- Patented Mar. 13, 1917.
posed gripping jaws 12 and folder blades 13, alternately spaced, the gripping jaws on one cylinder being timed to coact with the folder blades on the opposite cylinder, and transfer pins 14, adjacent to each jaw, to carry the folded paper from one cylinder to the other, so that the pieces are delivered alternately by the cylinders in folded and interleaved stacks. Paper is fed in continuous webs 15 to opposite sides of the machine, passing through feed or guide rollers 16 and over the adjacent folding cylinder where a severing device 17 cooperates with each cylinder to cut the paper into suitable lengths for forming towels and the like.
Each severing device comprises a pair of diametrically Opposed, stationary cutting blades 18, carried on rotatable arms 19, which blades are adapted to coperate with and enter a slot 20 formed in the cylinder adjacent to eachfolder blade 13. A rubber gripping block 21, carried on each arm 19 in front of each blade 18, upon coming in contact with the cylinder engages the paper and positively holds it against tearing or slipping until it has been severed by the blade 18 entering the slot 20, as best shown in Fig. 2.
Immediately in the rear of the cutting blade 18 and attached to the arm 19 is a guard block 22 normally pressed outward by a spring 23 and which, upon meeting with the adjacent cylinder, forces the severed end of the incoming web of paper down adjacent to the folder blade, while a set of pick-up pins 24, carried on the cylinder and movable outwardly, pierces the leading end of the paper and retains it in place compelling the web to be drawn around with the rotating cylinder. Thisy guard block, being normally projected, comes in Contact with the cylinder before the blade 18 enters its slot; and in conjunction with the gripping block 21 serves to hold the paper taut while the blade is doing the severing. The guard` block, thereafter, strips the paper from the blade and holds it in position to permit thel trolled .in its movement by a crank connection 3l with an external cam 32; whereas the gripping jaws 12 in each case are carried on a similar rock shaft 33 having a crank connection 34 with an internal cam 35. Each ofsaid rock shafts, it will be.noted, extends through the hollow cylinder and is controlled in its movement by a separate cam mechanism; the whole being timed in proper order to produce the desired operation.
Each gripper jaw operates in a. slot 36, formed in the wall of the cylinder, and is normally engaged withfone side thereof, but when nearing contact with the folder blade on the' opposite cylinder is caused to be opened by the cam 35, whereupon thefolder blade 'forces a bight of paper therein, consisting of two sheets, as shown in Fig. 4;` one sheet a being creased near its severed end and the other sheet b being creased near its middle on account of entering upon opposite cylinders. Immediately the jaw is closed to engage the bight of paper and the transfer pins 14 adjacent to the jaw are" moved by their cam mechanism intoengagement with openings 37 in the opposite cylinder, thereby impaling the sheet .b and also the sheet c, (sheet c being `the one on the op# posite cylinder preceding sheet a), and causing said sheets to be transferred to the adjacent cylinder. As the members turn away from each other the folder blade is Withdrawn from the jaw.` and the sheetc 're-` moved from the pick-up pins and the paper carried with the jaw to a point near the bottom of the travel of the cylinder where it is released,-depositing the l lag end of the l sheet @interleaved partially with -the sheet opposite severing device is-driven by a, spur;
gear 43 from the gear 39, thesp'eed of the b and with the front portion of the sheet a. The leaves thus delivered consist` of a sheet folded on a'median line andalso near its margin, said sheet overlappinghalf its distance with the preceding sheetand being.y
overlapped the remaining distance by the succeeding sheet.
The cylinders 10 and 11 aregeared to- I gether by spur gears 38 and 39, respectively,
gear 38 being driven by a spur gear 40 ona shaft 41 of the adjacent severing ldevice, which latter-shaft constitutes the drive shaft and is operated by a drive pulley 42. The
cylinders' and severing devices being uniform.
As will be understood, the folded strips of paper are delivered alternately by the 'cylinders in interleaved stacks, and it has been customary 'heretofore to allow the material to fall ydirectly beneath the cylinders `in piles to be removed by 'hand at intervals. We have devised simple and improved mechanism to deliver the folded material directly from the cylinders to one side of the machine in compact and continuous order,
The pulleys 59 are carried -idly on asurp port 61', beneath the cylinder 10, while t pulleys 60 are xed upon a shaft 62 jourinder 11.
formed in the cylinder. Lying below, and
adjacent to each series of stripper fingers, is a tumbler bar 47 running the full length of the cylinder and having a plurality of longitudinally arranged ribs or teeth 48 vformed upon its periphery and spaced endwise apart to leave circumferential depres! I sions or grooves 49 1n l1ne with the fingers.
vSaid lingers normally rest in' the grooves 49 of the tumbler bar, and the rock-shaft 45 is working ou an external cam 51 to push the .fingers up into the grooves 46 on the adjacent. cylinder in timed relation with the reg,-
lease of the gripping jaws 12,'thereby stripplng the folded paper therefrom and directing it down against a tooth on the tumbler l bar, which tooth turns the edge of the paper ,downward and away from the. rapidly rotating cylinder and on to a belt conveyer 52.
For operating each tumbler bar, we employ a ratchet drive comprising a toothed wheel- 53 fixed upon one end of said bar, a vibratile arm 54 adjacent to said wheel and loose on the bar carrying a pawl 55 to engage 4with the teeth on the ratchet wheel,
' and a reciprocal rod 56 having a crank pin and disk connection 57 with a shaft 58 driven by the spur gear on the adjacent foldlng cyllnder. The timing between the tumblervbar and cylinder is such that the latter makesy two revolutions to one of the tumbler bar,fand inasmuch as the cylinder, as nowl machine, operating over pulleys 59 and 60.
naled upon the side of the frame and actuated by 'a ratchet drive, said drive comprisi ing a ratchetwheel 63, 'a pawl and vibratile .1 arm 64, and ay connecting-` rod 65. having a" 85 A operable through a crank .connection 50 tumbler bar adjacent to the cylinder 10 and 1'2'5l vrangedbe ts 67, running at one end over the f;
arrangement upon thetumb er bar, prevent the paper from being carried downwardly' by the teeth on that bar and away from the .horizontal belts 52. Cooperating with the belts 52, and Working upon pulleys carried lupon the shaft 62, are supplementary con; Y veyers or belts 70 traversing 4a delivery table 71, at which place an'attendant receives themoving stack of folded papers for bundling and wrapping the saine. i
In order that the attendant shall knownI without countinggwhen the required number of strips of paperis at hand to constitute a bundle, we provide a marking device whereby afolded towel or -tissue lis' markedV at ,regularlyfspacedintervals insuch a Way that-'the mark will bevisibl'e'tothe attendant; This marking mechanismis embodied the marking roller and impression roller isthe machine adJacent to one-set of feed 'rollers 16 and comprises an impression roller 72 in contact with the driven feed roller and:
i i provided with a rubber stop 7 3 upon its pe'- lriphery' to 'coperate with a steel lug or markerv 74 upon a marking roller 75. O ne ofthe feed rollers is driven by an adjacent Then when the stackofpapers is deliveredv j tothejbench 71, the mark printed ont-he 'I paper by the marking device appears upon 1 the exposed edge of one of the towelswhere the operator can see the same and` readily idler pinion 58a on the shaft 58 through'a spur gear 76 in mesh therewith, and the impression roller 72 is provided with a spur ear 77 to mesh with the gear 76 on the eed roller, while the marker roller is driven by the impression member by means of a spur gear 78 the train of gears, it will be'noted, being driven by the spur .gear on the adjacent folding cylinder. lThe gear 77 ,ron theirnpression roller, is provided, say, with twenty-fourteeth, whereas the gear 78, on the marker roller, has twenty-five teeth.
A. composition-wheel orinking roller 7 9 cooperates with the steel lug or marker to supply ink thereto. The' paper .15 passes between the marker and impression rollers,
around the latter, and thi'ough'theA feed rollsuch that a-contact between the steel lug and as marking Contact between .the impression "''andfmarking rollers would 'occur at interrubber stopv takes place at every twenty-fifth revolution, and the' timing between. the im- .i pression roller and the'. foldingcylinder' causes the former to makevv two revolutions i i to one of' the latter." Paperbeing fedv from vboth sides ofthe machinev onto the cylinders," `each revolution of the cylinders "produces four folded'piece's ;l which would mean that vals" offfifty towel:s'.' -'15I"he mark-will like- I. l wise be printed at a iined'point'in the'rota tion of thel rollers. Hence .it -may' b e 'are ranged to take place 'in'such' a position 'on-"- the aper as to be visiblefon the edge v'of fthe olded strips presented outward, as atI on certain of thetowels. --In the operationof the {device .just de- VSCIOGd, the. paper is. .fed tothe cylinders 'Y' from one side of the machine,rone of the Webs running above the vmachine over a bailshaped guide 80, passing between the markf The webs en'- l" rock-shafts to enter the grooves on the cylward into 'engagement with a'tooth on the inders, whereupon theaction of the gripper y Ljaws releases the folded strips, allowing .the stripper fingers to move the same down-18I tumbler bars.
