CIGARETTE-TUBE MACHINE.

SPECIFICATION forming partof Letters Patent No. 577,347,118tt6d February 16, 1897. A pli tion fil d December 8,1891. Serial No. 414,402. (No model.)

' this specification.

My invention relates to machines for forming and preparing blanks, whereby they are adapted for making tubular wrappers and mouthpieces for cigarettes, which are preferably of conical or tapered shape, and although the machine, as hereinafter described, and

shown in the drawings, does not form the blanks into complete tubes it will for the sake of brevity be called a cigarette-tube machine.

The object of my invention is to provide improved means for cutting the blanks from rolls or sheets of paper and for applying paste to them preparatory to their further treatment. The nature of my improved devices will be best understood as described in connection with the drawings, in which they are illustrated, and in which- Figure l is a side elevation of a machine embodying my improved devices. Fig. 2 is a plan View of the machine; Fig. 3, a front elevation of the parts of the mechanism shown in Fig. 4; Fig. 4, a side elevation of the ma chine, showing those parts which are cut away in Fig. 1. Figs. 5, 6, and 7 are views of the feed-rolls and cutting-dies, illustrating the operation of the dies in severing the blank. Fig. 8 is a plan view of the female die and the guard-plate immediately above it, Fig. 9 being an edge View of the same devices. Fig. 10 is a plan view of the carrier; Figs. 11 and 12, views illustrating the action of the nippers used for carrying the blanks into contact with the paste-roll. Fig. 13 is a plan view of a piece of paper from which the blanks have been out; Fig. 14, a view of one of the blanks, and Fig. 15 a view of the cigarette-- tube rolled from the blank.

A indicates the framing of the machine, upon which the movable parts herinafter described are supported.

B is the table, which supports the paper before it reaches the feed-rolls, B indicating that part of the table which extends to the delivery side of the feed-rolls and in which the female die to be hereinafter described is formed or attached.

0 is the driving-shaft of the machine, D and D being fast and loose pulleys.

E is a gear-wheelsecured on shaft 0, and E a gear meshing with gear E and secured on the counter-shaft F. G is a cam secured 011 and turning with shaft F; H, a rodwhich, as shown, rests at one end on the shaft F by means of yoke H, while at its other end it is attached at I to a lever I, journaled on shaft J.

H is a cam-roller secured on rod H and resting on cam G, which gives to it and the rod H a reciprocating motion, which is imparted, of course, to the rock-lever I.

1 is a pawl having a weighted end 2', which keeps its active end 'i in contact with a ratchetwheel K, which ratchet-wheel is secured to the shaft J.

L is a star-cam having a series of &c., and preferably one point Z of greater length than the others. This cam is secured to the shaft J and receives an intermittent movement of rotation through the action of the pawl I on ratchet-wheel K, the movement of rotation being equal in each case to the length of a cam-section Z and the cam-wheel L remaining stationary, while the pawl I is moved back to take a fresh hold on the ratchetwheel K.

M is a rod conveniently supported, as shown at M, on shaft J on one end and at its other end attached to one arm of a bell-crank lever N, which is journaled on shaft N. A camroller M is secured to the rod or slide M and rests in contact with the cam-wheel L, the action of which is to give the rod M an intermittent reciprocating motion and through it to communicate an intermittent oscillating or rocking motion to the bell-crank lever N, which carries on one arm a pawl N said pawl resting on and actuating a ratchet-wheel N secured to shaft N, which is thus given an intermittent rotary movement. To shaft N is also secured a gear-wheel N which is in gear with the wheel 0, secured to shaft 0 upon which is also secured the upper feedpoints 11,

roll 0'. The wheel 0 is in engagement with a similar wheel 0 on shaft 0 upon which shaft is secured the lower feed-roll 0 The shaft 0 as shown, is supported and its roller 0 held against roll 0 by a lever O, pivoted at O and attached, as shown, to a spring 0 It will readily be seen that by the mechanism described the feed-rolls O" and O are given an intermittent rotative movement and that by the action of the cam Z a movement of greater length is given to them at regular intervals. The purpose of this, I will here explain, is so that when the machine is fed with strips of paper instead of by a continuous roll the action of the cam-finger Z, which should be first to come into operation, will carry the paper through a greater distance than the action of the fingers Z, which necessarily come into operation afterward. In this way the front edge of the strip is fed to the required distance over the rear edge of the female die, and the subsequent shorter movements of the strip are just sufficient to feed an uncut portion of the sheet over the die, and the blanks are thus cut with the greatest possible economy.

The number of the canrfingers and the arrangement of the parts actuated by them are such that a single rotation of the cam-wheel L will correspond with the passage of a single sheet of paper through the machine.

I is a female die formed in or secured to the part B of the supportingtable. The form of the die is that desired for the blank, and I prefer that the corners should be rounded, as shown, and above the table B is secured a plate P, between which and the die P the paper is fed from the rolls 0 0 The plate P is cut away above the opening in the female die in corresponding shape, so as to give passage to the male die P, which is secured to a slide P said slide being attached at its upper end to a lever P secured on shaft P to the other end of which is attached the connecting-rod P, which, as shown, is held in position at its lower end by a yoke P passing over the shaft F, and has attached to it a cam-roller P which rests upon a cam-surface Q, said cam being attached to and moving with the shaft F and the formation of the cam being such as to lift the rod P and force the male die down during the period when the feed-rolls O" O are out of operation, raising it again above the plate I or the lower surface thereof before the motion of the feed-rolls is resumed. The downward motion of the male die causes it to pass into the female die, severing the blank from the sheet or roll of paper and forcing it down into or through the female die and onto a receiver or carrier situated below the female die. I prefer, however, to limit the downward motion of the male die, so that its lower edge will pass but a short distance below the upper edge of the female die, and to carry the blank through the female die and onto the receiver I employ a stripper R, which fits into a cavity of the male die and is attached to a slide R, connected at its upper end with a lever R pivoted on shaft R the other end of the lever R being connected with a rod R which, like the rod P, is steadied by means of a yoke at its lower end passing around shaft F and is provided with a cam-roller R, which rests on a cam-surface Q, attached to shaft F and rotating with it, the shape of the cam Q being such as to give a motion to the stripper-arm corresponding to the motion of the male die, but prolonging its downward motion, so that after the male die has operated the stripper will continue to move down, pushing the blank through the female die and onto the receiver. This action of the dies and strippers is clearly indicated in Figs. 5, 6, and 7 of the drawings.

The blank having been carried through and freed from the female die is now to be transported to the pasting devices, which apply p'aste to one of its edges. The receiver, therefore, should be a movable one, and such a receiver I have indicated at S, the receiver having a cavity, as shown, (see Fig. 10,) corresponding to the outline of the blank. As shown, and for use with the nippers to be hereinafter described, the receiver or carrier has a slot 8 formed through its bottom along the side on which the edge to be pasted rests. It is attached to a slide S, supported in proper bearings on the frame of the machine and havin g a cam-roller which fits into a cam-groove in a cam-roll S the cam-groove being of the general outline shown in Fig. 2 and having two straight sections S and S at its two extreme positions, so that the carrier S will remain stationary for a time beneath the female die and for another time at the extreme point to which it is moved by the action of the cam S. This cam, it will be noticed, is secured to the shaft C and is constantly rotating with it. By the action of the cam the carrier S is moved from beneath the female die to the posit-ion indicated in Figs. 11 and 12, in which position a presser-foot or nipper U extends above it with its edge a over the slot .5'. (This nipper U is attached to a slide U, and is freeto move up from the position shown in Fig. 11 to that shown in Fig. 12, where shoulders U come in contact with the lower edge U of the slide-guide, arresting further upward motion.) This position of the carrier S also brings it above a nipper V, which registers with the slot 3 and is supported upon a shoulder \V of a slide TV through the medium of a spring V which intervenes between the lower end V of nipper V and the shoulder \V. The slide \V has attached to it a plate or finger V which lies alongside of the nipper V, as shown in Fig. 11.

To the slide is attached a cam-rollerW, which rests against a cam Y, the roller being held in contact with the cam-surface by the action of a spring W and the cam having a depression y, which permits the spring to tion on the cam-roller.

draw the slideW up when it comes into opera- This cam, it will be noticed, is secured to and rotates with the shaft 0. When the slide W moves up, it carries with it the nipper V, which, moving through the slot 3, presses the blank against the nipper U and continuingto move upward carries the blank and the nipper U upward to the position shown in Fig. 12, where further upward motion in the nippers is arrested by the shoulders U The slideWcontinues to move upward, the spring V yielding, and the plate l/V moves past the edge of nipper V, pushing the extreme edge of the blank against the paste-roller T and thus preparing it for the further operation of making it into a tube, as indicated in Fig. 15. The action of the nippers V U is timed to take place during the rest of the carrier before it moves back to its position beneath the female die, and this backward motion may begin at any time after the nippers have seized the blank, the nippers returning, of course, to their original position before the carrier returns with a new blank.

I have not shown in the drawings any mechanism for removing the blank after its edge has been pasted or for carrying on the further operations necessary in forming or filling the tube, my present invention having no reference to such mechanism, but simply going so far as the formation of the blank and the application of paste to it.

It only remains to note the mechanism by which the paste-roll is operated.

' T is a paste-box having in it paste-rolls T and T the roll T having a part of its surface exposed and lying immediately above the edge of the nipper U. The paste-rolls are geared together and given an intermittent motion of rotation by means of a pawl t acting on a ratchet secured to the shaft of roller T, said pawl being secured on the end of a rock-lever i actuated through a connecting-rod t by a lever-arm secured to the shaft P This shaft is a rock-shaft receiving its motion from the lever P, which is attached to it and which is actuated,as before described, by the cam Q and operates in turn the male die. By this arrangement it will be noted the motion of the feed-rolls corresponds with the motion of the male die, so that the pasterolls are stationary during the time when the carrier lies beneath them and while the nippers are lifting the blank to its surface.

It is of course apparent that the specific arrangement of cams, connecting rods, &c., illustrated in my drawings could be very greatly Varied without departure from my invention, and except where the said specific mechanism is especially referred to in the claims I do not wish to be understood as limiting my invention upon its use.

It is also apparent that the machine herein described, and shown in the drawings, can

.be used for forming and preparing blanks of paper or similar material and adapting them for tubes which may be used for other purposes than cigarette wrappers or mouthpieces, and I do not wish to limit my invention to tubes of any special shape or for any special use.
