tain new and useful Improvements in Appaf ratus for Cutting and Folding Toilet-Papers,

of which the following is a specification.

The present invention relates to a machine by means of which two endless webs of paper V are alternately cut up into definite lengths,

folded into one another, and ranged in layers on a table, as in the case of toilet-papers.

One embodiment of the present invention is illustrated in the accompanying drawings,

in which I Figure 1 is a part-sectional side elevation of the machine; Fig.2, a longitudinal section on the line as r of Fig. 1, in which the right half of the machine is considered turned round to the right; Fig. 3, an enlarged diagrammatic representation of parts of Fig. 1, in which all the cylinders are shown turned through one hundred and eighty degrees, the machinefranie being omitted. Fig. 4 shows a pile of papers which have been cut and folded into one another, the places where the separate portions of the two webs of paper have been out being rendered particularly conspicuous.

Fig. 5 shows a plan View of the table and the flexible weight-lever mechanism, and Fi 6 shows a side elevation of the mechanism ilTustrated in Fig. 5.

The operative cycle of the machine is as follows: The cylinders a a and b b are connected together by means of the toothed wheels g g. The cylinders a a are provided with the grooves f f, in which during the process of cutting the cutting-knives g g, secured on the cylinders b b, engage. The position of these cutting-knives g g and the position of the grooves ff on the cylinders a a for receiving them must in each of the two cases be displaced. exactly through one hundred and eighty degrees with regard to one another, so that the place where the paperweb 1) is cut is always situated exactly centrally between two places where the paper- Web 10 is out. The cylinders a a, are provided with recesses v 0, produced by turning out the cylinders eccentrically, and each of the latter are also provided with two rows of points or spikes e e, whichin the case of both cylinders are likewise displaced though one hundred and eighty degrees with regard to one another, so that the cut paper-webs are always pricked through on the cylinder a or a, at the cut laces and are carried to the right or to the eft, Figs. 1 and 3. The points e e are so arranged that upon the rotation of the rolls the points e will register with the grooves f in the roll a and the points e on the roll a will register with the groove f in the roll a. By this means the points will be protected from injury. The proper folding and piling up or superposing of the paperwebs laid the one in the other are now effected by means of the strippers or grippers d d, which are alternately and in opposite directions moved u and down by means of the system consisting of the connecting-rod h, lever-arm i, lever-arm It, connecting-rod Z, and arm m. These strippers are so set that in the raised position (Fig. 3 on the left) they are received in the recesses'c c in the cylinders, whereas during their alternating descent they strip off the paper from the points 6 e. By this means the desired fold is simultaneously formed, which told is still further intensified by the pressure of the strippers d d on the superposed pile of papers. in order to regulate the steady growth of the pile of paper and to keep the same always at the same height under the strippers, the table n must be movable and must be balanced by springs or weights, so that it can move downward according to requirement.

In Figs. 5 and 6 the details or construction of a flexible table for receiving a pile of material is illustrated, and in accordance with the construction disclosed herein a tableboard n rests between the standards of the machine and is supported on four arms 1', carrying rolls 8, and each of which arms is supported by a pair of links t t, pivoted to it and the standard. The links t are shown continued into the arms or levers t, which are provided with slots These levers t at each end of the machine are connected by and carry a rod u, which is adjustable in said slots w. Each of the rods it carries a weight a). By this means the vertical position of the table may be regulated and adjustment may be had between the respective ends of the table, as occasion may demand.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination of a pair of rotatable cylinders adapted to seize two webs of paper and draw the same between them; one web passing round one cylinder and the other web round the other cylinder, and each Web being transversely cut into separate portions at uniform intervals, the cuts on one web ly ing midway between those on the other web; a row of spikes on each cylinder, the row on one cylinder being dodged relatively to the row on the other, whereby portions of the two webs may be carried partially around the periphery of one and then another portion partially around the periphery of the other cylinder, and means for stripping the webs from the cylinders and laying the same in a pile.

2. The combination with a pair of cooperating rotatable cylinders adapted to draw between them two webs of paper, of two rolls one cooperating with each of the said cylinders, each roll and its cooperating cylinder being adapted to feed one of the webs of paper between them, a knife on each roll, a row of spikes on each cylinder whereby portions of the two webs are carried alternately in folds partially around the periphery of the respective cylinders, and means for stripping the webs from the cylinders and laying the same in a pile.

3. The combination with a pair of coop-- erating rotatable cylinders adaptedto draw between them two webs of paper, of two rolls one cooperating with each of the said cylinders, each roll and its cooperating cylinder being adapted to feed one of the webs of paper between them, a knife on each roll, one knife being so arranged with regard "to the other that the cuts on one web come to lie midway between those on the other, a row of spikes on each cylinder whereby portions of the two webs are carried alternately in folds partially around the periphery of the respective cylinders, and means for stripping the webs from the cylinders and laying the same in a pile. I

4. The combination with a pair of cooperating rotatable cylinders adapted to draw between them two webs of paper, of two rolls cooperating with each of the said cylinders, each roll and its cooperating cylinder being adapted to feed one of the webs of paper between them, a knife on each roll, one knife being so arranged with regard to the other that the cuts on one web come to lie midway between those on the other, a row of spikes on each cylinder, the spikes on one cylinder being adapted to engage the Web fed by the other cylinder near the places whereit is cut, whereby portions of the two webs are carried alternately in folds partially around the periphery of the res ective c linders, and means for stripping te webs om the cylinders and laying the same in a pile.

5. The combination with a pair of cooperating rotatable cylinders adapted to draw between them two webs of paper, of tworolls one cooperating with each of the said cylinders, each roll and its cooperating cylinder being adapted to feed one of the webs of paper between them, a knife on each roll, one knife being so arranged with regard to the other that the cuts on one web come to lie midway between those on the other, a row of spikes on each cylinder the spikes on one cylinder being adapted to engage the-web fed by the othercylinder near the places where it is cut, whereby portions of the two webs are carried alternately in folds partially around the periphery of the respective cylinders, a table whereon such portions are piled, a number of recesses in each cylinder, arms adapted to enter such recesses and upon movement of the same toward the table to strip thepaper from the spikes, and" means controlled by the rotation of the cylinders to alternately actuate said strippers.

6. The combination with a pair of cooperating rotatable cylinders adapted to draw between them two Webs of paper, of two rolls one cooperating with each of the said cylinders, each roll and its cooperating cylinder being adapted to feed one of the webs of paper between them, a knife on eachroll, one knife being soarranged with regard to-the other that the cuts on one web come" to lie midway between those on the other, a row of spikes on each cylinder the spikes on one cylinder beingadapted to engage the webfed by the other cylinder near the places where it is cut, whereby portions of the two-'webs'are carried alternately in folds partially-around the periphery of the respective cylinders, a movable balanced table 'whereon such portions are piled, a number of'recesses in each cylinder, arms adapted to enter such recesses and upon movement of the-same toward. the table to strip the paper from the s ikes, and means controlled by the rotation o the cylinders to alternately actuate said. strippers.

7. In an apparatus of the character described, the combination with two IOlls, of means for feeding sheets or units from opposite directions down between the rolls and so timing the feed as to compel the sheets to overlap, and means for folding and interfolding the sheets or units as they pass between and from the rolls.

In witness whereof I: have hereunto signed my name, this 4th day of April, 1905,in the presence of two subscribing witnesses.
