PAPER SLITTING AND REWENDING MACHINE.

Specification of Letters Patent.

Patented April 23, 1907'.

Application filed July 1,1903. Serial No. 163,948-

To 01/ whom it may concern:

Be it known that I, FRANCIS MEISEL, a citizen of the United States, residing at Dorchester, in the county of Suffolk and State of Massachusetts, have invented a new and useful Paper Slitting and Rewinding Machine, of which the following is a specification.

This invention relates to that class of slitting and rewinding machines which are employed in paper-mills or other places for trimming and slitting a web of paper and wifiiding the same into a number of separate ro s.

The especial objects of this invention are to provide a strong, simple, and inexpensive paper slitting and rewinding machinewhich will occupy comparatively little room, to provide for properly tensioning the paper as it is drawn into the machine, to provide means for readily and quickly adjusting the slittingcutters either longitudinally or laterally with respect to their shafts, and to provide automatic stopping connections for stopping the operation of the machine when web-rolls of the desired size have been formed.

To these ends this invention consists of the paper slitting and rewinding machine, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying three sheets of drawings, Figure 1 is a front view of a paper slitting and rewinding machine constructed according to this invention. Fig. 2 is a side view thereof, partially broken away. Fig. 3 is a detail view of the automatic stopping connections. Fig. 4 is a similar view showing the parts in a different relative position. Fig. 5 is a detail view of the means for laterally separating the slitting-cutters. Fig. 6 is a similar view Showing the parts in a different relative position. Fig. 7 is a detail view of the means for securing the relative trans verse adjustment of the slitting-cutters, and Fig. 8 is a similar view showing the parts in their adjusted or cutting position.

Referring to the drawings for a detail description of a slitting and rewinding machine constructed according to this invention, the framework of the machine comprises side frames A A, which side frames, as illustrated most clearly in Fig. 2, are connected -at the top by a cross-rod B and near the bottom by the cross-braces C and D and the shelf S. The shelf S is omitted from Fig. 1. for the sake of clearness,

Journaled at the top of the side frames A is a hoisting-shaft 10, having the sprocketwheel 11, which is driven by a chain 12 from a sprocket-wheel 13, having an operating crank or handle. Secured on the hoistingshaft 10 inside of the side frames are the sprocket wheels or drums 14, extending down from which are chains having hooks 15 for raising the separator-shaft. The separatorshaft 16 moves up and down in ways inside the side frames A and is provided with one or more cylinders 17, carrying thin separatingblades for completing the work of the slittingcutters to divide the web of paper into two or more separate web-rolls W W, which are wound. upon a rewinding-shaft 18, which also moves up and down in the bearings on the inside of the side frames and which rests upon the winding-

drums

19 and 20. The

windingdrums

19 and 20 are secured upon the

shafts

21 and 22.

Carried by the shaft 21 is a gear 23, and carried by the shaft 22 is a gear 24. The

gears

23 and 24 mesh with and are driven from the driving-gear 25, which is driven by friction through suitable stopping connections, as hereinafter described.

The slitting-rolls act upon the paper before it passes up and over the front winding-drum 19. As shown in Fig. 2, a gear 26 is secured on one end of a stud through to the inside of the frame, which is provided with a gear 27, which is of larger diameter than the gear 26. Meshing with and driven from the gear 27 is the gear 28, which is secured on the shaft carrying one set of the slitting-cutters 29. Meshing with and driven from the gear 28 is a gear 30, which is secured upon the shaft 35, which carries the other set of slittingcutters 31. By the use of this drivinggear ing for turning the slitting-rolls it will be seen that the difference in diameter between the gear 26 and the gear 27 will impart a slightly higher peripheral speed to the slitting-cut ters than the speed of travel of the web, whereby the slitting-cutters will secure a shearing cut and at the same time will act as coaxing-rolls for holding the web tight.

The means for laterally separating the slit- Figs. 1, 2, 5, and 6. As shown in these figures, a rock-shaft 32 is journaled in the frames and is provided at one end with an operating-handle Extending up from gage with notches in theboxes which carry ting-cutters are most clearly illustrated in.

the rock-shaft 32 are the arms 34, which en- ICC the slitting-cutter shaft 35.

By means of this construction two sets of slitting-

cutters

29 and 31 may be laterally separated while the machine is being adjusted or threaded up. The means for adjusting the slittingcutters longitudinally of their shafts is most clearly illustrated in Figs. 1, 2, 7, and 8. As shown in these figures, an adjustable handle 36 is provided with a stud 37, which is threaded into the box of the shaft 35 to engage the end of the shaft 35 and move the same endwise. The opposite end of the shaft 35 is engaged by a spring 38. By means of this construction when the handle 36 is moved to turn back its stud 37 the end spring 38 will move the cutter-shaft 35 endwise to separate the slitting-

cutters

29 and 31, as shown in Fig. 7. While by tightening the handle 36 the side faces of the slitting-cutters may be positively set up into engagement, as shown in Fig. 8.

The automatic stopping mechanism for automatically stopping the machine when the web-rolls of desired diameters have been wound is most clearly illustrated in Figs. 1, 3, and 4. As shown in Fig. 1, 40 designates a framework for supporting a fixed stud journaled on which is a friction-pulley 41. The female section of the friction-pulley 41 may be driven by belt from any suitable source of power, and the male section of the frictionpulley 41 may be expanded into frictional engagement therewith by the expanding-levers 42 in the ordinary way. Turning with the male member of the friction is a drivingpinion 25. A lever 43 is arranged to release or clamp the parts of the friction-pulley together, as desired. The lever 43 is connected at its upper end to a spring 44, which acts to normally release the friction-pulley. Extending from the face of the operating-lever 43 is a lug 45, which is engaged by a trigger or lever 46. The rear end of the lever 46 rests upon a collar 47, secured on the vertically-movable rod 48, and extending from the rod 48 is an arm49, which is engaged by the rewind ing-shaft 18 when web-rolls of the desired diameter have been wound onto the rewinding-shaft.

In the operation of the complete machine the paper P, as shown in Fig. 2, may be drawn from any suitable source of supply and passes either over or under the brace C, around the brace D between the slitting-

rolls

29 and 31, over the front winding-drum 19 to the web-rolls which are wound on the rewinding-shaft. The passage of the paper around the braces C and D is intended to give it the proper tension, which is increased by the fact that the slitting-cutters operate at a higher have been wound the operation of the machine will be automatically stopped. The separator-shaft may be lifted up out of the way by the chains and tackle, before described, and. the completed web-rolls may then be pushed forward onto the shelf S, the

bottom section of the strips which forms the front sides of the ways in which the rewinding shaft and separator-shaft run being pivoted to permit this to be readily done.

I am aware that numerous changes may be made in practicing my invention by those who are skilled in the art without departing from the scope thereof as expressed in the claims. I do not wish, therefore, to be limited to the construction I have herein shown and described but hat I do claim, and desire to secure by Letters Patent of the United States, is

1. In a machine of the class described, the combination of a framework, winding-drums journaled in the framework, slitting-cutters, and gearing for turning the slitting-cutters comprising a shaft forming an intermediate connection between the winding-drums and the slitting-cutters, said shaft having agear on the outside of the framework of small diameter meshing with the gears of one of the the boxes of one of the slitting-cutter shafts to secure a transverse separation of the cutters.

3. In a machine of the class described, the combination of a winding device having gears, slitting-cutters having gears, and gearing for turning the slitting-cutters, comprising a shaft forming an intermediate connection between the winding device and the slitting-cutters, a gear on said shaft meshing with a gear connected with the winding de vice, and a gear of larger diameter also on said. shaft meshing with a gear connected with the slitting-cutters, whereby the slitting-cutters will be driven at a higher peripheral speed than. the speed of travel of the web.

4. In a machine of the class described, the combination of two sets of slitting-cutters, a pair of shafts on which said slitting-cutters are mounted, movable boxes in which one of said'shafts is journaled, said boxes having notches, a rock-shaft having an operatinghandle, and arms extending therefrom for entering the notches to move the box and laterally separate the cutters, one the said shafts also being movable longitudinally in its bearings.

5. In a machine of the class described, the combination of two sets of slitting-cutters, one of said slittingcutters having its shaft journaled in movable boxes, a rock-shaft having an operating-handle and arms en gaging the boxes to laterally separate the cutters, the shaft of the movable set of cutters being movable endwise in its bearings, a spring engaging one end of the shaft, and a threaded stud engaging the other end of the shaft to adjust the cutters laterally into engagement.

6. In a slttingand rewinding machine, the combination of means for supporting a roll, a winding-shaft for the roll movably mounted above said supporting means, whereby it may rise as the roll increases in size, means for operating the supporting means to turn a roll supported thereby, means normally tending to disconnect said operating means from a source of power, a lever for-holding the operating .means connected with the source of power, a vertical guide-rod, and an arm movable along said rod and connected with said lever, the arm being inthe path of the winding-shaft, whereby when the shaft rises to a certain point the lever will be tripped and the disconnecting means will operate.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

FRANCIS MEISEL.
