Fig.- 9 is an endview, as viewed from the left, of the portion of the apparatus illustrated in Fig. 8. Fig. 10 is a plan View of parts not shown in Fig. 9, but situated at the right of the parts shown in said Fig.9. Fig. 11 is a derail plan view of a portion of the apparatus not so specifically shown in Fig. 1, and Fig. 12 is a vertical sectional view taken in the line y y of Fig. 11.

Supported in suitable bearings a is a revoluble hollow sleeve A, which may be revolved by a bandewheel ct or other suitable means and which has fast upon it a spur-wheel 1). Extended from the end of this sleeve isa the inner layer of the tube is to be formed.

Fast axially at one of its ends to the inner end of the sleeve is a mandrel 0, upon which thematerial is wound in the production of the tube and the diameter of which determines the internal diameter of the finished tube. This mandrel'is made detachable from the sleeve in order that mandrels of difierent diameters may be used according as tubes of different internal diameters are to be made. Arranged in due relation with the opposite end of the mandrel to sever the tube ata point beyond said end is the cutting-0d mechanism by which, as hereinafter explained, the continuous tube is severed into sections of the lengths desired. The mandrel being fast to the sleeve, as explained, it necessarily rotates therewith.

The ribbon d, of paper, from the reel 13 passes lengthwise through the sleeve and makes its exit from one side of the interior thereof to and upon the adjacent part of the mandrel. A spring 1; is arranged to press upon the ribbon as it passes to the sleeve inorder to hold the ribbon under proper tension.

Supported in a fixed annular bearing 6, suitably alined with the sleeve, is a revoluble annular head A, which has at one side and fast to it an annular spur-gear f. By means of a spur-pinion c this spur-gear f connects witha spur-wheel f on a counter-shaft g, which, supported in suitable bearings, is below and parallel with the sleeve. At its opposite end this counter-shaft connects by a spur-wheel g and pinion f" with the spurwheel b of the sleeve, so that the spur-gear f is driven from the rotation of the sleeve.

The mandrel passes through central opening a of the head, as more fully illustrated in Fig. 5. At opposite sides of the opening a the head carries two revoluble feed-rolls 6 one upon each side of the mandrel. These rolls are adjusted by means of screws 77, and are circumferentially grooved, as illustrated in Fig. 6, on semicircular curves corresponding to the diametrical size of the mandrel,

their oifice being to feed the ribbon cl to and along the latter, said rolls being rotated in the proper direction by motion-transmitting devices hereinafter presentlydescribed. The feed-rolls b in addition to their'feeding motion are revolved or carried bodily around the axis of motion of the mandrel and in the same direction with the rotating motion of the mandrel and the core carried thereon, but with only about half the speed of the mandrel, the latter in its revolutions slipping within the core to an extent corresponding to the difference of its revoluble speed as compared with that of the core. While, therefore, the core formed upon the mandrel rotates more slowly than the mandrel, and consequently more slowly than the sleeve and the reel, it follows that ,the ribbon is wound upon the mandrel to an extent proportioned to the excess of the speed of the sleeve and its mandrel over that of the core, which is retarded by the slower revolutions of the head with its feed-rolls. Meanwhile the slower motion of the head with its feed-rolls is sufficient to insure the winding thereon of a further number of layers of paper, as hereinafter explained.

The feed-rolls, it will be observed, serve the double purpose of regulating the revoluble speed of the core upon the mandrel and of feeding the core longitudinally along the latter.

The requisite motions are given to the feedrolls by appropriate mechanism, which, as shown in the drawings, is provided for operation as follows: Supported by and rotating within a fixed annular bearing h is a barrel or hollow cone B, which has at one end a spur-gear 7?, while its opposite end projects into the space a of the head A and preferably works smoothly therein, as indicated in Fig. 5. This smaller end of the barrel has a spur-gear 7L4. Each feed-roll b has at one end of its shaft a worm-wheel i.

The head A is provided with bearings 2' for short shaft-s k, each of which has at one end aworm 7a, which gears with the adjacent worm-wheel 2', while at'its opposite end is a spur-pinion 7a, which gears with the spurgear 7%. As the head A and barrel B rotate at dilferent rates of speed, the revolutions of the head carrying the spur-gear 75 around the spur-gear h of the barrel motion is transmitted through the worm-wheels and to the feedrolls to feed the ribbon of material to and along the mandrel, as hereinbefore'described. As the ribbon d passes from the sleeve to the barrel it is guided in its course to the mandrel by a sloping or curved block j, carried by the sleeve and revolved thereondary shaft D, parallel with the axial line of the mandrel, sleeve, head, and barrel, has a spur-pinion Z, which gears with the spur-gear 7b2 of the barrel. On this shaft is a ratchetwheel m. Pivoted on the same shaft is a swinging bar m, at one end of which is a spring pawl m, which engages with the ratchet-wheel m. At the opposite end of this bar is an antifriction-rolleron, which receives the impact of a cam 'n, on the shaft g, which, as hereinbefore explained, is rotated through the spur-gears b and g and pinion f". Pivoted in a fixed bearing is a hand-lever n, on which is an eccentric n Around this eccentric 71- passes a strap on the end of a longitudinally-mova ble rod 01 the opposite end of which is pivotally connected with the arm of the swinging bar m, this being preferably accomplished by a switch or vent in the end of the rod bearing against a pin it on the bar and pressed against the latter by a spiral spring n By manipulating the rod by means of the hand-lever and its eccentric the lower or impact end of the swinging bar 772 may be moved more or less from the path of the cam 11, so that the action of the cam upon the swinging bar may be varied in degree with a proportionate change in the extent and duration of the action of the pawl upon the ratchet wheel, a proportionate change in the extent of each impulse given to the rotation of the barrel, and a proportionate modification in the speed of the feed-rolls carried by the head. In the operations above described the ribbon d is wound spirally upon the mandrel as the sleeve rotates and the ribbon is fed thereto, the wound ribbon being moved along the mandrel as this feeding proceeds. This ribbon thus fed and wound upon the mandrel forms the core of the completed tube.

To complete the tube, it is essential that a further number of layers of paper or like material be wound around the core formed, as just described, by the ribbon cl. This is provided foras follows: Placed suitably adjacent to the mandrel is a paste-box E, in which is provided a paste-feeding roller 7', upon the shaft of which is a gear 1". Above this roller and geared therewith by a pinion r is a paper-feeding roll .9, and behind this latter are reels F, proportioned in number to the number of strips of paperor the like to be wound upon the core, as just explained. In the drawings, Fig. 1, three strips are shown at u, and the apparatus is so arranged, as illustrated in said figure, that the strips in passing to the core on the mandrel are oblique to the latter, the degree of this obliqueness detel-mining the pitch at which the strips are wound upon the core. The ends of the strips are at the outset of the-operation attached to the core, so that the strips are drawn to and wound upon the core as the latter revolves with the mandrel and is carried longitudinally along the same, as hereinbefore explained. As the strips pass over the pastefeeding roll their inner surfaces are coated with paste or adhesive material, so that when wound theyadhere to the surfaces upon which at H in Fig. 11.

after cutting the tube, it is retracted to its lar sleeve, a mandrel revoluble with the said they are wound. From the oblique position of the strips with regard to the mandrel as they pass to the latter it follows that the strips reach the mandrel in, so to speak, successive order, so that while the firststrip in order is pasted direct to the surface of the core the second strip in order is wound upon and pasted to the outer surface of the second after the latter has been wound upon the core and the third in like manner over and upon the second, so that the completed tube comprises,with the core and three strips, four plies of material pasted or cemented one upon another. Inpractice it is preferable that the paste-feeding roller 1' be provided with a scraping-roller q to regulate the thickness of the paste thereon in feeding the paste to the strips, and tension-bars 25 may be providedto regulate the tension of the strips as they pass from the reels to the paste-roller.

The paste-roller, the roller 3, and the scraping-roller should be geared together, as shown To hasten the drying of the paste when the stripsof material are wound upon the core, as described, a gas-burner G may be arranged in proper relation to the parts to dry the material as it passes along the mandrel, as described. As the tube thus produced may be continuous of a length to any degree proportioned to the length of the ribbon and the strips of material fed'thereto, it is desirable that it beautomatically cut into such lengths as may be desired for commercial or other uses. To provide for this, the invention includes the mechanisms shown more in detail in Figs. 8, 9, and 10 of the drawings.

Mounted in bearings upon a suitable frame at that end of the apparatus remote from the sleeve and its adjuncts is a shaft I, which carries a circular saw K and has a pulley I,

through which from any suitable source motion'may be transmitted to the saw K. This shaft is capable of a longitudinal movement in its bearings and is connected,as presently explained, with the upper end of a "lever K,

the lower end of which works in connection with a cam K on a counter-shaft K which;

latter is driven through a pulleyL from any suitable operating power. proportions of the cam K should be such that when the cam actuates the shaft I to move the saw, as herein presently to be eX-' plained, the saw will move at substantially the same speed and in the same direction that the tube moves along the mandrel. When, as presently explained, the saw is released original position by a spiral spring M, acting upon its shaft.

Extended beyond the saw,as shown in Figs. l, 8, and 10, and supported in suitable guides or bearings are two parallel rods or bars R and R.

a and at another portion of its length a clutch b which connects with'the upper end of a lever 0 the lower end of which has a stud The speed and On the bar R is a stop or shoulder R operatesthe lever c to. bring the stud'd in the path of the stud 6 the movement ,of the cam is stopped. The pulley L, it may bementioned, has a frictional hold upon its shaft, so adjusted that when the cam is free the pulley end rotates the latter; but when the cam is stoppedby the stud diet the lever the friction is overcome and the pulley'runs free without rotating itsshaft. This is the condition when the saw is not in operation, and the bar. R isretracted to produce this result bya spring Sf", applied thereto, as indicated in'Fig. 8. Upon the bar R is provided a lever T,

whichat one end has'a contact-plate T,which contact-plate and swings the lever T. This,

latter then slides the bar Rto operate the lever 0' to bring its stud d away from the cam K which latter is then rotated and actuating the saw through the lever K carries thelatter along at the same speed as the tube. It is now necessary that the tube and saw be brought into such relation with each other that the saw will pass transversely through the tube to sever a section therefrom. To provide for this, the end of the tube which has passed from the mandrel is supported in a trough N, whichis carried on a framewhich is pivoted at its back, as shown at N in Fig.

9. From this frame extends an arm N the free end of which rests upon a cam 71 (shown in dotted 'outline' in Fig. 9) upon the shaft K of the cam. This cam t lifts the end portion of the tube against the saw, and the latter being simultaneously carried along in the direction of the length of the tube the end por tion of the latter'is cut squarely off in a plane 'at right angles to the length ofthe tube.
