Specification of Letters lPatent.

Ifatented Sept. 3, 1912.

To all whom-it may concern.

Be it known that I, FRANCIS MEIs'EL, a citizen of the United States, residing at Boston,-in the county of Suffolk and State of Massachusetts, have invented a new and useful Machine for Making Toilet-Paper Rolls, of which the following is a specification.

This invention relates to a machine for cross-wise perforating, slitting, and rewinding the strips on one shaft to make toiletpaper rolls.

The principal objects of the invention are to provide a construction in which the mill roll bearings will readily adjust themselves to any position the shaft for the mill roll may assume and to provide for adjusting themill roll: so that the web w ll be drawn without wrinkles; to provide improved means whereby a space is secured for passing the paper quickly through .the machine and pulling the web taut and smoothso that when the machine starts the web will not be wrinkled to provide for adjusting each bearing' in which the pressure rolls are mounted independently on the machine; to provide for moving the two pressure rolls away from the lower perforating cylinder so as to secure room for entering the paper and to bring the same against the lower perforating cylinder instantly and with. the same pressure;

to provide a simple and convenient means for separating the slitting cutters and raising the top shtter shaft in combination with the means'for throwing on or of the pres sure rolls, and to provide an improved frie tion driving mechanism for winding loose or soft rolls and incombination with a surface winder for winding hard rolls so that the machine can be used for either purpose at will.'

The invention also involves details of construction as will appear hereinafter.

Reference is to be had to the accompany ing drawings in which Figure 1 is a plan of a machine construct-- ed in accordance with this invention. Fig. 2 is aside elevation of the same. Fig. 3 is a sectional. view on the line 3-% of Fig. Fig. 4 is-a sectional view on the line 4& of Fig. 3. Fig. 5 is a sectional view on the line of Fig. 2. Fig. 6 is a side elevation of the web roll stand therefor. Fig. 7 is a studs on the machine. is provided with an adjusting screw 20 and a driving shaft 11 provided with a driving pulley. 12 adapted to be connected with the shaft by a friction clutch 13 of any desired character, operated by means of a lever 14 or the like. On this shaft is located the lower perforating cylinder 15 and the shaft is geared to the upper perforating cylinder 16' as will be understood. These elements constitute a perforating device and may be of any well known type.

At the sides of the lower perforating cylinder are located the pressure rolls 17. These are mountedv 1n open-ended bearings .18 on four levers 19. These bearings are adapted to be closed by pins 20 which can be removed for the purpose of removing the pressure rolls. These levers are pivoted on between each pair of adjusting screws is a 22. This shaft is provided with an arm 23 which is adapted to be operated by a con-- nection '24. This connection is provided with two slots 25 and 26 and there is a fixed stop 27 on the frame so that as the connec tion is moved back and forth it will be stopped in its two extreme positions. In the position shown in Fig. 2 this brings the cam 21 to a position in whichit forces the lower arms of the levers 19 away from each .other agalnst the force of two springs 26.

This causes the pressure rolls to press against the lower perforating cylinder.

hen the connection 24 is moved inwardly the cam is oscillated so as to allow the springs to pull-the arms in and move the. ressure rolls apart. In this way a space is opened up very quickly between each pressure roll and the lower perforating cylinder for arranging the Web between the same. Thus the web can be inserted quickly and pulled taut and smooth. so that the machine can start without Wrinkles in the web. This is an important improvement over the usual type of machines in which the feedrolls, can be only slowly adjusted up against the perforating cylinder, thus preventing any quick motion such as that indicated.

To allow the web to be readily passed be- Each of these levers T cam 21, both mounted on an oscillatory shaft in detail in Figs. 3 and 4 is provided. The

shaft 11 through a gear 29 mounted on an,

adjustable arm 290 drives the lower slitter shaft 30, which has its bearings in blocks 31 mounted on the frame. Mounted to slide vertically in guides on the frame are blocks 32 which support the upper slitter shaft 33. These blocks 32 are supported from the blocks 31 by strong springs 35. The shaft 33 isnormally pressed in one direction longitudinally by a spring 36 mounted in a casing 37 on the block 32 at one end. At the other side of the machine there is a sup port 38' for an adjusting screw 39. Obviously the adjusting screw can be forced inwardly against the force of the spring 36, to move the shaft 33 longitudinally as it bears on the end thereof. At the top of the frame on each side are bearings for a parallel shaft 40 on which are mounted two cams 41, each adapted to press on a projection 42 on one of the blocks 32. An arm 43 is mounted on this shaft for turning it. This arm has stops 44 for limiting its motion. A check nut 45 is set on the screw 39 in such position that when it comes into contact with the support 38 the slitting cutters 46 will be in proper position. The object of the spring and screw in the top boxes is to separate the cutters so that the cutters cannot be injured by raising and lowering the upper shaft.

In order to pass the web between the slitting .cutters, each pair of cutters is separated by moving the upper shaft longitudinally by means of the screw 39. Then the top shaft with the slitting cutters is raised by turning the shaft 40 so as to permit the springs 35 to force the blocks 32 up. It will be seen therefore that the paper can be passed between the perforating cylinders and their pressure rolls and between the slitt-in cutters very rapidly without waiting for tedious adjustments and without introducing the liability of wrinkling it in getting it into the machine.

For rewinding the paper so that it can be rewound either in hard or soft rolls the following mechanism is provided. Driven from a gear 50 on the lower slitter shaft is a shaft 51 which by means of chain 52 constantly drives a sprocket wheel 53 mounted to loosely turn on a shaft 54. This sprocket wheel is provided with a cup-shaped projection 55 in which is'a fiber disk or the like 56. Mounted to slide on the shaft 54 and keyed thereon so as to rotate it is a clutch member 57. The shaft 54 is journaled at its end in a member 58 fixed on the frame and provided with a screw-thread 59 on its outer end. On this thread is arranged a worm wheel 60 and a worm 61 is mounted onthe frame for operating it. hen this is turned shaft to rotate with it.

the wheel 60 will be screwed on or unscrewed. If turned so as to be unscrewed it will move the member 57 to the left in Fig. 5 and force the friction disk into frictional engagement with the cup' so that the rotation of the sprocketwheel will cause the The shaft or stud 54 is provided with a socket 62 in its end in which fits the end of a shaft 63 so that the latter shaft will be turned with the shaft 54. At the other end this shaft is mounted in a bearing 64 and removably held therein by a guard piece 65 secured in position by a bolt 66 or the like.

The friction driving the rewinding shaft is one of the most important features on a machine manufacturing perforated toilet roll paper, because there is no strength left to speak of when the paper is perforated. This friction acts instantly when the machine is started, preventing slack of paper between the slitters andrewinding shaft; at the same time it slips so that the surface speed of the rewinding shaft may be greater than that of the paper.

In'the above described construction loose soft rolls arewound, the comparative tightness of winding being regulated by the worm. -I wish, however, to provide for winding hardrolls on the same machine and for that purpose a surface winder is shown driven by a sprocket-wheel 70, mounted on the lower slitting cutter shaft 30 and connected by a chain '71 with a sprocket-wheel 72 located on a stud on which stud are pivotally mounted levers 73, one of them having a handle. On one lever are gears driven from a gear on said stud, the last one'mounted on a shaft '75 on which is located a cylinder 76 that is adapted to engage the roll on the rewinding shaft. Arms 77 rigidly connected with the arms 73 are provided with adjustable counter-weights 78 so that the cylinder 76 can be held up in position at any desired pressure.

The web roll shaft 80 is mounted in two bearings 81 having open ends and is held in position by removable pins 82. One of these hearings is mounted on a flat top surface on one side of the frame 10 and the other is mounted on a similar surface on top of an oscillatable casting 83 on the other side of this frame. ,The bearing members 81 are held in position on these surfaces by vertical bell-shaped extensions 84 located in open topped conical or cylindrical openings 85 in the surfaces on which the bearings rest. The casting 83 can be moved toward or from the frame by means of a rod 86 threaded through a nut 87 on the casting. The rod is provided with a hand wheel 88 for rotating it and thus adjusting this end of the web roll shaft. By this means the bearings can adjust themselves to any posi- 4 matter to adjust the mill rolls "so that the 97 for adjusting the tension.

web will be drawn; to the feed rolls smoothly and without wrinkles. The friction is shown as secured by a band 90' "passing over a friction wheel91 on themilli roll shaft, one end of the band beingsecured to. the frame" by a pin 92 and the. other having a.- hook 93 in which rests a pin. 94 on a lever 95. This lever is pivoted} at 96 on the frame and! is provided. with an adjustable counter-weight For the purpose of moving the web. rollshaft longitudinally to adjust it to proper relation to the perforating device, a rod 9 8 is shown provided with a crank 99 for operati-ng it and screw-threaded into.- a nut 100 on the end of a bell-crank.- 101 which, has a roll 102 extending into a groove 103 in the end of the wheel 91. The-operation will be obvious.v In this way it will be seen that the above mentioned difliculties are guarded against and a practicable and efiicient machine is secured for cross-wise perforating, slitting, and rewindingthe .web in either loose or hard. rolls.
