MACHINE FOR MAKING PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 659,599, dated October 9, 1900.

Application filed July 7,1900. Serial No. 22,869. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES A. BAILEY, a citizen of the United States of America, residing at Cromwell, in the county of Middlesex and State of Connecticut, have invented new and useful Improvements in Machines for Making Paper Tubes, of which the following is a specification.

This invention is an improvement in machines for making paper tubes employed in the manufacture of paper-tube cartridges; and the object of the said invention is to construct a machine of this character that shall be entirely automatic in its operation, feeding the paper to an arbor upon which it is tightly wound and the thicknesses pasted together, cutting the paper when the required thickness of tube is had, and then stripping the completed tube from the arbor.

The invention also-includes the idea of lapping the paper upon the arbor to insure its proper engagement therewith in starting the tube and. makes provision for removing the surplus paste from the finished tube as it is ejected from the machine, and, furthermore, it provides for changing the size of the arbor, whereby the tube is more easily removed therefrom.

With the above objects in view the invention consists, as a whole, of an arbor supported in vertical movable bearing, a pastepot into which the arbor is lowered, gearing by which said arbor is revolved when at its lowermostposition, mechanism for feedinga continuous sheet of paper to the arbor and cutting said paper at intervals, a device for lapping the paper upon the arbor to insure its proper engagement therewith, a stripper adapted to push the finished tube from the arbor, and a Wiper for cleaning the surplus paste from said tube as it passes from the machine, all as hereinafter fully described in the following specification, and more particularly set forth in the appended claims.

The invention also consists in novel combination of parts and special features of construclion embodied in the machine.

In the accompanying drawings, which form a part of this specification, and in which like letters of reference indicate like parts throughout the several views, Figure 1 is an end elevation of a tube-making machine constructed in accordance with my invention. v Fig. 2 is a front elevation of the machine proper, the paper-roll and its supporting-frame being removed. Fig. 3 is a front elevation of the main part of the machine removed from the supporting-frame, a part being broken away to show the gearing which operates the stripper. Fig. 4 is a vertical sectional view on the line 44 of Fig. 3. Fig. 5 is a vertical sec tional view on the line 5 5 of Fig. 3. Fig. 6 is a detail longitudinal sectional view of the winding-arbor and its movable support. Fig. 7 is a detail sectional view of the winding arbor. Fig. 8 is a detail sectional view of the paper-cutting rolls.

The mechanism of the machine is supported by a frame consisting of castings or end pieces A A, which are connected together near their lower ends bytie-rods a a and are braced at their upper ends by the shafts andparts which they support, the said end pieces providing integral bearingboxes a a, in which is journaled a horizontal shaft B, carrying the operating cam-wheel, hereinafter described.

0 designates a frame or casting which is mounted upon the end pieces A A and forms practically the top of the supporting-frame of the machine, the upper part of said frame presenting areceptacle or pan 0, which holds the paste that is applied to the paper as it is wound upon the arbor in forming the tube. The paperis guided into position below the arbor by means of a guide-plate c, which extends over the front wall of the receptacle or paste-pan, down the inner side thereof, and is curved upward at its lower end, as shown in Fig. 5. The curved lower'end of the plate 0 serves to press the paper against the arbor, so that it will be readily caught and wound thereon. Q

Slidably mounted in a casing A, bolted to the forward end of the machine, is-a vertical plate A forming the movable support for the arbor D, and for the purpose of providing a mesh with the driving mechanism only when the arbor is lowered into the paste-pan to wind the paper thereon. The arboris hollow throughout its length, and that part of the same upon which the paper is wound is split (see Figs. 6 and 7) in order that it may be expanded laterally to form a paper tube of a certain diameter and then contracted to permit said tube to be more easily pushed therefrom by the stripper or ejector, hereinafter described. The arbor is therefore made of spring-steel, and the split portion is contracted in its normal condition and is ex panded by means of a fiat strip D, having a stem located in the stem of the arbor, one part being provided with a spiral groove d, engaging a screw d of the other part, so that when the expander D is moved longitudinally in the arbor it will be turned independent thereof and spread the bifurcated portions of said arbor. To provide for moving said expander, the projecting outer end thereof has a swivel cl with arms 01 the latter extending into an irregular slot in the depend iug members e e of a bracket E, supported at the ends of guide-rods ff, and said projecting end of the expander is supported by slotted arms d carried by the tubular bearing 0. It will be observed that the bracket E is stationary and that the slot 6 is disposed at such an angle that when the arbor and spreader are lowered by their supportingframe the said spreader will bepushed inward; also, that the spiral groove d and screw d are so arranged that upon an inward movement of the spreader the latter will be given a quarter-turn, bringing the ends of the flat portion of said spreader to bear against the bifurcated port-ions of the arbor, thereby separating them and increasing the diameter of that portion of the arbor, and, furthermore, that the disposition of said slot is such that the arbor will be expanded when at its lowermost position and contracted when raised to its uppermost position. Rubber strips 61 are let into the sides of the arbor to form surfaces which will better adhere or catch the paper and start it upon.the arbor.

The plate A, forming the movable support for the arbor, is raised and lowered bya pinion g, meshing with rack-teeth a on said plate, the pinion being turned by a slide G, having a set of rack-teeth g, in mesh with a pinion 9 mounted on the same shaft as the pinion g, said shaft g being journaled in a housing a bolted to the casing A, as shown in Fig. 3. The slide G extends longitudinally of the machine, being located in the upper part of a groove or channel 0 in the under side of the frame 0, and passes through the casing A and housing of. The other end of said slide-bar G is provided with a set of rackteeth 9 in mesh with a pinion g on a shaft g, carrying also a pinion g meshing with a rack a, formed on a vertical slide-plate A The; shaft 9 is supported in a housing (1 similar to housing a at the other end of the .a rib i on the cam-wheel I. .served, therefore, that a movement of the machine, and the plate A has a vertical movement in a casing a bolted to the frame or casting O. The plate A is provided for the purpose of carrying a device or arm H, which is moved into engagement with the free end of the arbor D when it is lowered to prevent an upward movement of the free end of the arbor as the paper is wound thereon and is moved out of engagement with said arbor when in its uppermost position to permit the tube to be pushed therefrom. It is obvious, therefore, that the movable supporting-plate A should have a greater movement than the supporting-plate A which carries the arbor, and this is provided for by having the pinion g which meshes with the slide G, smaller than the pinion 9 which meshes with the vertical rack, while the pinions g and g for raising and lowering the vertical plate or support A are of the same size as pinion 9 It will be observed also that as both supporting-plates A and A are raised and lowered in unison the rack-teeth at the ends of the slide G are at opposite sides of said slide and engage the upper part of the pinion at one end of the machine and the lower part of the pinion at the other end of the machine. The slide G is moved by a cam-wheel I, provided with a rib e', engaging a depending lug g secured to the under side of said slide.

J designates the stripper or tube-ejector,

consisting of a sleeve adapted to slide upon the arbor and push the tube therefrom, the said sleeve having circumferential flanges forming a groove, into which fits a depending bifurcated portion 7a of a slide K, the latter being slidably mounted upon the guide-rods ff, hereinbefore referred to, said rods being supported in brackets a and a bolted upon opposite ends of the frame 0. The slide K is operated by a slide-bar L, secured thereto and extending therefrom through the brackets a and E, by which it is supported, the said slide-bar having a set of rack-teeth on its outer side, which teeth are in mesh with a pinion M, fast to the upper end of a vertical shaft m, supported in a suitable bracket a, the said shaft being turned by a pinion M, fast to its lower end, being in mesh with a large gear-wheel N on a shaft it, having a pinion N, in mesh with the rack-teeth of a slide 0, mounted in the frame below the slide G, and havinga depending lug o, engaged by It will be obslide 0 back and forth will reciprocate the slide-bar L through the intervention of the gearing hereinbefore described,and said slidebar carrying the slide K, which is imengagement with the tube-ejector J, will reciprocate said tube-ejector to push the.tube from the arbor; also, that the interposed large gearwheel N provides for the movement of the tube-ejector the entire length of the arbor, and, further, that the gearing of the parts is such that the slide which operates the tubeejector does not commence to reciprocate until the arbor is moved to the limit of its upward movement.

The bracket (1, is provided with an opening through which the tube passes as it is ejected from the machine, said opening being 011 a line with the upper position of the arbor, and at the inner end of this opening is a tubular projection 19, supporting a flexible washer or wiper P, held in place by a flanged ring 19, screwed onto the said tubular projection. This washer or wiper is of little less diameter than the tube, and as said tube passes through the same will scrape the surplus paste therefrom. It will be understood, of course, that the slide A is provided with an opening on a line with the opening through the bracket a to permit the finished tube to pass therethrough, and, if desired, a trough may be provided to receive the tube as it passes from the machine and deposit it into a basket or other receptacle.

Q designates the driving-shaft of the machine, on which is the band-pulley Q, said shaft being journaled at its inner end in a box a, formed integrally with one of the end pieces A, and at its outer end is journaled in a cross-bar Q supported by rods q, projeciing from said end piece. This drivingshaft has a gear-wheel R mounted thereon in vertical line with the pinion D at the outer end of the arbor and so located that said pinion will mesh therewith when the arbor is in its lowermost position, for it is only necessary that the arbor be revolved during the winding of the paper thereon. Said driving-shaft also carries a pinion Q, in mesh with a large gear-wheel B on shaft B, upon which the cam-wheel I is mounted. The driving'shaft also has a band-pulley Q", by which to drive the paper-feeding mechanism hereinafter described.

In feeding the paper to the machine, either separate sheets by hand or a continuous sheet by way of the feeding mechanism, it is passed under the arbor a sufficient distance, so that when said arbor descends it will push it down into the guide-plate or curved former a and into the paste, and in order to insure the proper engagement of the paper with the arbor it is folded over upon the same by a swing: ing plate S, which is pivoted at its ends in blocks 3, secured to the bottom of the pastepan, and is operated by a lever S, pivoted in a bracket 0 secured to the rear end of the frame 0 and connected to said plate by a connecting-rod s and arm 8 (See Figs. 4 and 5.) As the paper is folded over upon the arbor by means of the pivoted plate S said paper is creased, and, if found necessary, an elevated trough may be provided to feed a supply of paste between the thicknesses of the fold. The pivoted lever S is operated by a lug i on the cam-wheel I engaging the foot of said lever.

The paper-feeding mechanism is supported in brackets T T, having tongues t at their lower ends engaging corresponding grooves in the upper ends of the end pieces A A of the main supporting-frame of the machine. In these brackets are mounted a pair of papercntting rolls U and U, one above the other, said paper-cutting rolls being preferably covered with felt or othersoft material to give the required friction and insure the proper feeding ofthe paper. The shafts or gudgeons at one end of the cutting-rolls extend beyond the bracket and carry pinions u and u, in mesh with each other, the gndgeon of the lower roll U being farther extended to receive a bandwheel 10 over which passes a belt from the band-pulley Q on the driving-shaft. The paper (lettered V) is inserted between the feed-rolls and the roll of papersnpported in a suitable frame, Fig. 1. As the paper is not fed continuously to the machine, means are provided for stopping the paper-cutting rolls and releasing them, consisting of a dog w, adapted to engage a recess in the lower roll and operated from the cam-wheel I by means of an arm it), fast to a shaft W, to which said dog is also made fast. Lug 1' strikes arm 10' to operate the shaft W, and said shaft is journaled at its ends in frames T. The paper is cut into the proper lengths by the rolls U and U, one having a longitudinal cutting-blade and the other a recess or groove into which the blade forces the paper and cuts it. By providing the groove the rolls.

retain ahold upon the paper. Tension on the paper is provided for by intermediate guide-rollsYand Y, supported in end frames and normally separated by springs 11 to permit the paper to readily pass between them and are brought together by arms Y depending from the slides A and A and engaging the extended ends of the shaft of the upper roll. Guide-rolls z z are interposed between the paper-roll V and cutting-rolls.

i From the foregoing description, in connection with the accompanying drawings, the construction and operation of my invention will be apparent to those skilled in the art to which it applies, for, assuming that the parts are in the initial position, as shown in the drawings, the feeding mechanism operates to feed the paper under the raised arbor. The slide G is then moved to operate the mechanisms atthe ends of the machine, which lower the arbor and press the arm H against the free end thereof, said arbor carrying the paper with it down into the paste and upon the curved former 0, while the pivoted plate S operates simultaneously to fold the end of the paper upon the arbor. As said arbor is lowered the split portion thereofis expanded by the spreader and reaching its lowermost position the pinion D comes into mesh with the gear-wheel R, which rapidly revolves the arbor, causing the paper to be wound thereon, the paste being supplied by reason of the arbor being partly submerged therein. As soon as the paper has been wound upon the arbor, thereby forming the tube,

the said arbor is then raised by the interposed mechanism, and the stripper J coming into engagement with the slide K the latter is moved forward to push the tube from the arbor and is then returned to its normal position,this operation of the slide being efiected by the slide-bar O, which actuates the gearing that revolves the pinion M, which is in mesh with the rack-bar L, secured to said slide. This operation is repeated in forming a second tube, and so on.

The machine is adapted to form a very long tube, and therefore the free end of the arbor upon which the tube is formed is steadied by means of the depending arm H, which is brought into engagement with said free end when the arbor is lowered and is moved out of engagement when the arbor is raised, as hereinbefore described, so as not to interfere with the removal of the tube by the ejector.

As heretofore suggested, paper sheets of the required size can be fed into the machine singly by hand in lieu of using a continuous sheet and the mechanism hereinbefore described for feeding said sheet and cutting it. In case individual sheets are employed said sheets could be supplied with paste before their introduction into the machine.

The split arbor in connection with the rotatable core or spreader provides for expanding and contracting said arbor to facilitate the removal of the finished tube, as hereinbefore stated, and though I prefer to use this particular arbor in the machine it is evident that a solid arbor will answer the purpose, especially if said solid arbor is triangular or polygonal in cross-section. It is also obvious that the gearing mechanism for actuating the several instrumentalities could be changed without departing from the spirit of my invention,for other Well-known mechanical contrivances could be employed for raising and lowering the arbor, reciprocating the stripper or tube-ejector, and actuating the automatic paper-feeding mechanism.

The machine constructed in the manner herein shown and described provides for performing the diiferent' functions automatically, and as all the parts are positive in action the machine will really require no attention whatever other than to supply the paste and paper.
