MACHINE FOR MAKING COlLED-PAPER TUBES.

srnorrrcn'rron forming part of Letters Patent No. 586,054, dated July 6, 1897.

Application filed October 9, 1896.

To all; whom it may concern:

Beitknown that I, HENRY A. NOBLE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Machines for Making Coiled- Paper Tubes, of which the followingis a specification.

My invention consists of certain improvements in paper-tube machines whereby sucro ccssive strips of paper are spirally coiled one upon another and the superposed layers secured together by the action of the spiral run of an endless belt, of which any desired number may be used, the object of my invention r 5 being to provide for readily changing the an gle of the presserbelt or belts without slackening or tightening the same or stopping the machine.

In the accompanying drawings, Figure 1 is a side elevation of a paper-tube machine constructed in accordance with my invention. Fig. 2 is a plan or top view of the same. Fig. 3 is a transverse section on'the line as 00, Fig. 1; and Fig. 4 is a plan or top view of a modi- 2 5 fled construction of part of the machine.

The fixed frame or bed of the machine may be constructed in any available manner, this element of the machine consisting in the pres ent instance of a pair of channel bars 1,

mounted upon suitable lugs 2 and having at one end a structure 3, which carries the hollow spindle 4, to which is suitably secured one end of the mandrel 5, upon which the tube is formed and from which it is delivered 3 5 as produced, the outer end of the mandrel being unsupported. Turning loosely upon the spindle 4 are a pair of pulleys 6 and 7, the pulley 6 receiving the belt 8 from a pulley on anyavailable drive-shaft. The hub of 4.0 the pulley 6 has secured to it a spur-pinion 9, which meshes with a spur-wheel 10, turning loosely upon a stud 11, carried by an arm 12, projecting from one side of the structure 3.

Secured to the spurwheel 10 and turning loosely with it upon the stud 11 is a spurpinion 13, which meshes with a spur-wheel 14 on a shaft 15, said shaft being adapted at one end to a bearing in the arm 12 and at the other end to a bearing in an arm 16, projecting from the bed of the machine at the opposite end of the same. Splined upon the shaft Serial No. 603,876. (No model.)

15 are bevel-pinions 17, which mesh with bevel-wheels 18 at the lower ends of vertical shafts 19, the latter being free to turn in bearings 20, mounted upon transverse bars 21, which rest upon the opposite bars 1 of the fixed frame of the machine and have depending bolts 22, passing through bars 23, the latter bearing against the under sides of the bars 1 and the bolts being provided with nuts 24:, which when tightened serve to secure the transverse bars 21 seeurelyin the position to which they have been adjusted longitudinally upon the bars 1.

Upon each of the transverse bars 21 is pivotally mounted a swinging bar 25 by means of a bolt 26, these bolts being in line axially with the shafts 19, and the outer end of each of the swinging bars 25 carries a clamp 27, engaging with a segmental rib 28, formed upon the corresponding bar 21, the stem of the clamp being threaded and provided with a nut 29, so that either of the swinging bars 25 can be adjusted upon its carrying-bar 21 and secured in position after adjustment.

Longitudinally guided upon ways at the outer end of each of the swinging bars 25 is a slide 30, which has bearings for a vertical shaft 31 and also for a horizontal shaft 32, the inner end of this latter shaft having a bearing in a post near the inner end of the swinging bar 25. Each shaft 32 has at the inner end a bevel-pinion 34, meshing with the bevel-wheel 18 of one of the shafts 19, and at its outer end a bevel-pinion 35, meshing with a bevel-wheel 36 at the lower end of one of the shafts 31, said bevel-pinions 35 being splined upon the shafts 32, so that adjust ment of the slide 30 upon the swinging bar 25 can be readily effected.

Each pair of

shafts

19 and 31 carries a pair of belt drums or

pulleys

37 and 38, to which is adapted a belt 39, which runs from the right-hand side of one pulley to, over, and around the mandrel 5 and thence to the lefthand side of the opposite pulley, the return run of the belt crossing from pulley to pulley above the mandrel and being twisted in its course, so as to clear said mandrel, as shown in Fig. 3.

That portion of each belt 39 which surrounds the mandrel 5 follows a spiral course,

the angle of which is dependent upon the adj ustment of the pulleys 37 and 3S angularly in respect to each other, and this is effected by swinging upon the bar 21, the bar carrying the outer pulley-shaft 31, the shaft 19 constituting the fixed shaft of the pair, and the axis of said shaft being the axis on which the frame 25 swings in effecting angular adjustment of the pulleys in respect to each other, so that said angular adjustment can always be varied without slackening or tightening the belt 39 or stopping the machine, thus overcoming an objection to which previous machines of this class with which I am familiar are subject.

In order to slaeken or tighten the belts 39 to adapt them for acting upon tubes of different diameters, the slides are adjusted longitudinally upon the swinging bars 35, such adjustmentbeingeifected by means of screws having hand-wheels 40 in a manner similar to that adopted in effecting adjustment of the tool-carriages of lathes and like machinery.

A bracket 41, mounted upon one of the side bars 1 of the main frame of the machine, carries at its upper end a guide 42 for the strip of paper 43, which forms the primary coil of the tube, said strip 43 being laid directly upon the mandrel 5, as shown in Fig. 2.

A red 44 is carried by arms 45 and 46, and upon this red 44 are mounted guides 4'7 and 48 for the strips 49 and 50, which form, respectively, the intermediate and outer coils of the tube which is being produced, these strips being coated with some suitable cement upon the under side before reaehin g the machine.

The strip 49 is subjected to the action of the first presser-belt 39 and is thereby pressed firmly upon the primary or inside coil of the tube, a second strip 50 being subjected to the action of the second presser-belt 39 and being thereby pressed firmly upon the second or intermediate layer, the finished tube passing from the outer end of the mandrel 5 to suitable cutting mechanism, whereby it is severed into lengths of the proper size.

Other strips may be fed to the tube between the presser-bclts or the number of presserbelts may be increased, as circumstances may suggest.

Although I prefer to mount the shafts 31 upon swinging bars pivoted concentrically with the shafts 19, such construction is not absolutely essential to the proper carrying out of the main feature of my invention. For instance, in Fig. 4 I have shown a modification in which the swinging frame 25 is dispensed with, the main transverse frame 21 having a central bevel-wheel 51, which turns on an axis concentric with the bolt 22, this bevel-wheel meshing with a pinion 17 on a shaft 15, to which said pinion is splined so that it can be moved with the bar 21 longitudinally on the main frame, but will always rotate with said shaft 15. lVith the bevel wheel 51 also en gage bevel-pinions 52, carried by shafts 0-4 which have bevel-pinions 94 and meshing, respectively, with a bevelwheel 18" on a shaft 19 at one end of the bar 21 and with a bevel-wheel 36 on a shaft 31 at the opposite end of said bar. It will be evident that in this case the swinging of the bar 21" upon the axis of the bevel-wheel 51 will not affect the relative position of the parts carried by said bar. Hence the construction will attain the same result as that shown in Figs. 1, 2, and 3. The bearings for the shaft 31 and pinion 35 are preferably carried by a slide 30, so as to provide for the movement of said shaft 31 from and toward the shaft 18 in order to slacken or tighten the winding belt.

It will be observed that in both of the c011- struetions shown the axis on which the swinging bar turns is concentric with the axis of the primary wheel of the power-transmitting gear, this wheel in the construction shown in Figs. 1, 2, and 3 being the bevel-wheel18, and in the construction shown in Fig. 4 being the bevel-wheel 51.

Having thus described my invention, 1 claim and desire to secure by Letters 1atent- 1.
