PAPERHCOP-TUBE MACHINE.

SPECIFICATION forming part of Letters Patent No. 341,028, dated May 4, 1886.

Application tiled July 6, 1ST?.

To @ZZ whom it may concern.-

Be it known that I, VILLLIAM M. MAR- UHANT, of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Paper- Cop-Tube Machines, which improvements are fully described in the following specification and illustrated in the accompanyingdrawings, in which-m Figure l represents a vertical longitudinal section of a machine having my improvements; Fig. 2, a top view of the same; Fig. 3, a perspective view of the wire rack, and Fig. 4 a perspective view of the ribbed plate used therein. Figs. 5, G, 7, and 8 represent1 certain parts of the machine in perspective.

In the manufacture of paper cop tubes, when the paper to form the tube is gummed or moistened only on one side, bad results are sometimes obtained for the reason that the paper is not presented in a lat'condition to the spindle upon which the said tube is wound or formed, owing to the warping or curling of the said paper produced by the expansion of the moistened side, producing tubes having ridges and other defects. Vhen Water is used to meisten the unpasted side of the paper to counteract this warping or curling, bad results likewise often follow, owing to the liability of the water coming in contact with the pasted side of the paper, causing the finished tube to stick to the spindle, thereby preventing its easy removal and producing a tube whose end or other parts are defaced or mutilated. Also, when water is used as above, certain parts of the paper become more or less saturated during the stoppage of the feed-rolls, and the said paper is therefore liable to be easily pulled apart or torn, causing much delay and imperfeet results. Further, in a machine where the removal of the tube is accomplished by the withdrawal ofthe spindle, and where the pressure or calendering roll is in contact with the tube during its removal and in contact with the spindle after the tube is removed and during the return of the said spindle to its original position, the said spindle becomes in a short time badly worn, owing to the friction of the said roll, necessitating the constant substitution of new spindles at considerable eX- pense.

My invention consists in certain features of construction and arrangement Vhereinafter described, and set forth in the claims.

Referring to the drawings, A A represent a pair of feed-rolls, which receive the paper a from a reel and present it to a paste roll or pulley, B, which runs in paste or gum contained in a box, C. This roll or pulley B per forms a twofold service. It carries the paper into the paste, thereby moisteuing with paste its under side, and from the fact that its face is wider than the paper, it carries up and transfers to the outer portions of the face of A the lianged roll D, arranged immediately above it, a certain amount of paste, to be afterward applied to the paste-plate E and to the upper side of the paper a. This roll D also acts as a squeezing-roll to remove from the under side of the paper nearly all the paste covering that side,'leaving the said surface in a damp or moist condition, which condition is sought from the fact that it prevents the warping of the paper.

That the pulley B may present a comparatively dry surface to the upper side ofthe in- Wardly-moving paper, the said pulley is provided with a doctor-plate7 or scraper, F, which removes from the face of the said pulley all paste that is not transferred to the roll I), the paste passing ofi' over the sides of the plate and dropping into the box G. This plate F is attached to a bar, f, which has a milled or ratchet head,f, which is in engagement with a spring-stop. The plate may therefore be adjusted to any required amount of pressure to insure the cleaning of the face of the pulley B. g

The paste-plate E is mounted the same as the plate F-that is, it is attached to a bar having a milled or ratchet head, e, which is in engagement with a spring-stop, c', as shown at Fig. 2. It operates to collect the paste from the outer portions of the face of the roll D and spread it upon the upper surface of the paper a. The amount of paste thus collected by the plate E is in excess of the amount required to properly gum the said upper surface of the paper, and this surplus amount passes back and falls on the pulley B, thence into the box C by the action of the plate F.

G G' are adjustable disks placed upon a IOO spindle, and serve to guide the paper centrally from the roll D to the bite of a second pair of feed-rolls, H H. The lower roll, H, has 'an unbroken periphery, while the upper roll, H', has a number of scores or channels around its circumference, and is pressed upon the under roll by weights 7L.

I is a horizontal wire rack, composed of a number of longitudinal wires fastened at their ends to'transverse bars, which serve to hold the said wires in place, the said bars having bearings in the frame of the machine. The wires of this rack pass through the scores in the roll H and prevent the paper from winding about the said roll, and offer but little resistance to the onward passage of the pasted paper toward the spindle.

K is a ribbed plate or equivalent arranged immediately below the forward portion of the wire rack l, its back edge coming in contact with the roll H, and it operates to prevent the pasted paper from winding about the said roll, and its surface being ribbed, it presents but little resistance to the moving paper.

L is a shear which, when sufficient paper has passed under to form one tube, descends by the action of the lever Z and cam Z, Figs'. 2 and 5, and severs the paper.

M is the spindle upon which the tube is wound, and hasupon its rear end a pinion, which is in train with other pinions, the gear N on the driving-shaft N imparting motion to them, thus giving to the spindle a continuous revolution.

Attached to the side of the gear N is asegnient of a gear, O, which, Working in a pinion, O', on the end of the shaft o, imparts through Y a proper train of pinions an intermittent motion to the feed-rolls A A, paste-rolls B D, and feed-rolls H H, the said rolls operating while in motion to supply to the spindle the necessary amount of paper to form a single tube.

P is a sleeve, which is splined to the spindle M and revolves with it. The sleeve P has aforward motion along the spindle for the purpose of removing the iinished tube therefrom, said forward motion being imparted toit by the levers p and p', which are operated by a cani, p2, on the driving-shaft. After the cam has performed its work the sleeve is returned to its original position by the force of a spring or equivalent operating upon the lever p', as shown in Fig. 6.

R is a rod, to which is splined a holder, S,

. which contains arubber iiap or flaps or equivaient, T, to which is given an upward motion for the purpose of lapping the paper around the spindle when the said paper is presented to it, and to which a downward motion is afterward imparted for the purpose of knocking the finished tube from the end of the sleeve P, to which it is likely to stick after the sleeve has removed the tube from the spindle. These vertical motions are imparted to the rubber iiap or equivalent and 4its holder by a partial rotary motion of the rod R, to which the holder is splined, the said rod having upon its end an arm, r, which is worked bya vertical lever, o". and horizontal lever r2, the latter being acted upon by a cam, r3, on the driving-shaft to produce the downward motion, and by a spring or equivalent acting upon the lever r, as shown in Fig. 8, to produce the upward motion of the said holder and flap.

At the time when the paper is presented to the spindle to be wound the rubber iiap or equivalent occupies a position immediately under and below that portion of the spindle upon which the tube is wound, as shown in Figs. l and 2. So soon, however, as the presentation of the paper is effected an upward motion is imparted to the flap, the paper is lapped on the spindle, and the holder and iiap occupy a position above and out of contact with the tube until the latter is' fully formed and ready to be removed.

Surrounding the rod R are two collars, R', which are connected to a short sleeve, R2, which is in turn connected to the sleeve P by a short arm, R3. Between the collars R the holder S, with its rubber iiap or equivalent T, are placed. Consequently, when the sleeve P moves outward to remove the finished tube from the spindle, the rubber iiap is likewise moved outward to be in a position, when the downward motion is given to it, to remove the finished tube from the end of the sleeve P, and likewise when the sleeve P returns after having cleared the tube from the spindle the rubber iiap, having knocked the tube off the sleeve P, returns with said sleeve to its original position immediately under the spindle, ready to lap on the said spindle the paper for a second tube. The layers of the forming tube are pressed closely together by the pressure or calendering roll U, which revolves, when in contact with the tube, between two arms, a a, attached to a rod, U', the said roll U being removed from the tube,when the latter is conipleted, by the action of the cam U2 and lever U3, and being brought up to contact with the forming tube and its pressure against the said tube maintained by a spring or equivalent operating upon the lever Us, as shown in Fig. 7.

The operation of the machine above described is substantially as follows: The paper a to form the tubes passes from a reel between ICO IIO

the feed-rolls A A,which feed it to the pastepulley B, running in paste or gum contained in the box C. Here the under side of the paper is moistened with paste to prevent the tendency to warp and to provide for a more thorough cementing of the layers of the tube. The paper then passes to the bite of the squeezing-roll D and pulley B, where the superfluous paste is removed from the said under side. Thence it passes up over the roll D and has its upper surface spread with paste by the paste-plate E, which is so arranged as to allow a thin iilm of paste to pass under it; or,if desirable, the edge of the said plate may be notched and the plate pressed upon the paper, so as to paste the upper surface in streaks or lines. The paper then moves onward between the guide-disks G G to the bite of the feeding-rolls H H', which pass it forward between the wire rack I and ribbed plate K and present it to the under side-of the spindle M. Vhen sufficient paper to form a lap has passed under the revolving spindle, the rubber flap or equivalent, by its upward motion, laps the paper upon the spindle and the rolling of the tube commences. Vhen sufiicient paper to forni a single tube has been fed forward, the feeding mechanism stops, and the shear L, operated by the cam Z and lever Z, descends and severs the paper, the short piece thus cut off being drawn onward by the revolving spindle. So soon as the tube commences to form, the pressure-roller U is raised by the action of the spring or equivalent above described, and continues in contact with the forming tube, pressing` the layers firmly together until the said tube is completed, when the roll is withdrawn by the action of the cam U2. Immediately upon the completion of the tube and withdrawal of the pressure-roll the cam p2 acts to cause the sleeve I to traverse the spindle to remove the finished tube therefrom, and at the same time to move outward the holder S and its rubber flap or equivalent T to a position ready to knock the tube from the end of the sleeve P. The cam r3 then acts to produce the downward motion of the iiap, knocking oft' the tube,which descends into a receptacle, V, properly placed. So soon as the iinal removal ofthe tube is completed the spring or equivalent, acting upon the lever p', (the cam p having finished its work,) quickly moves backward the sleeve I to its place,and with it the flap T to its position directly under the revolving spindle. Immediately upon the removal of the tube the feed-rolls begin to act to supply the paper for another tube, the end of the said paper being presented to the spindle by the time the flap T has reached its place underneath the said spindle, when, the cani r ceasing to act to keep the said flap in a depressed position,the spring or equivalent, acting upon the lever r-`,produces the upward motion of the flap, thus lapping upon the spindle the paper for a second tube, and the operations above described are repeated.

The advantages derived from the use of my improvements are as follows: The paper, being inoistened on both sides, is presented to the spindle in a fiat condition, and atube without ridges or other like imperfections is the result. Paste being applied to the under side of the paper, the layers forming the tube are more perfectly cemented together, and a closer-bodied and thinner paper may be used, producing at less cost a firmer and superior tube. My method of applying paste to the upper surface of the paper prevents any lumps77 from passing onto the paper, and secures a uniformly-pasted surface. By the use of the wire rack and ribbed plate the pasted paper is prevented from winding about the feed-rolls, and is presented to the spindle with a minimum amount of friction. By the use of the rotating sliding sleeve for removing the tube from the spindle, the end of the said tube is not enlarged or damaged. By removing the pressure or calendering roll from the tube after it is completed, the said tube can be more easily removed from the spindle, and the said roll not coming in contact with the spindle, there is no consequent friction, and the spindle lasts a very much longer time. By the use of the rubber flap or equivalent the paper is perfectly lapped upon the spindle and the finished tube securely discharged; and, iinally, the devices work to such perfection that one person is enabled to attend to a number of machines, thereby greatly reducing the cost of manufacture.

Having described my invention, what I claim, and desire to secure by Letters Patent, in a paper-cop-tube machine, is-

1. The combination of the paste-pulley B, the roll D, said pulley and roll being wider than the strip ot' paper passing over them, and paste-plate E, for applying paste to both sides of the paper, substantially as set forth,

2. The combination of the paste-pulley B, the roll D, said pulley and roll being wider than the strip of paper passing over them, the paste-plate E, and doctor-plate or scraper F, substantially as set forth.

3. The combination of the paste-pulley B, the roll D, said pulley and roll being wider than the strip of paper passing over them, the paste-plate E, and feed-rolls A A and H H, for feeding and pasting the paper, substantially as set forth.

4. The combination, with spindle M, of the shaft N', sleeve P, rod R, and holder S, arm r, levers r r2, and cam r3, and the ilexible flap or fiaps T, the said iap or aps having intermittent motions, as described, whereby `the end of the paper is lapped upon the spindle,

substantially as set forth.

5. The combination of the rotating sliding sleeve l) and flexible flap or flaps T with the continuouslyrevolving spindle M, for discharging the finished tube, substantially as set forth.

6. The combination of the reciprocating pressure-roll Uwith the revolving spindle M, rotating sliding sleeve P, and reciprocating iiexible flap or flaps T, for rolling up and discharging the tube, substantially as set forth.
