Specification of Letters Patent.

Application led August 30, 1910. Serial No. 579,628.

To allwhom it may concern:

Be it knowii thatI, SAMUEL M. LAXGSTON, a citizen of the United States, and a resident of Camden, in the county of Camden and State of New Jersey, have invented a new and .Improved '.lube-Making Machine, 0f which the following is a full, clear, and evact description.

This invention relates to certain improvements'v in machines for making tubes from strips of paper wound helically, and relates more particularly to that type of machine in which the paper is wound around amandrel and firmly pressed against the previously-applied strip of paper by a Ipresser belt, which has one run thereof =wound one 0r more times around the mandrel and tubing. In machines of this character, it is customary to mount the presser belt upon two pulleys upon opposite sides of the mandrel, and to mount these pulleys upon a member lnovable sol that the angle which the belt makes with the mandrel, may be varied to properly feed and press strips of paper of various widths. In some machines these members have been mounted to swing about the axis' of one pulley as a center, while in others they have been mounted to swing about a center midway between the two pulleys. In most machines, two members are employed, and in some machines, the two members have been connected together, so

.that they will swing simultaneously.

The object of my invention is to facilitate and simplify the adjustment. of the pulley and belt-carrying members, and to insure their simultaneous adjustmentfto the same angle. Toaccomplish this, I do not pivotally mount the pulley-carrying members, but mount them .to slide lengthwise upon a base, which latter is mounted to swing about a fixed center, and to carry the pulley-carrying members bodily therewith. Further- 'I more, I provide means for automatically sliding each member in respect to said base as the latter turns about its center, so that the pulleys will remain at approximately' equal distances from the mandrel.

My `improved machine has means for transmitting 'motion to the pulleys and presser belts, irrespective of the relative positions of the latterlinvrespect to the mandrel. The belts and .belt-carrying members may be adjusted lengthwise of the mandrel, to vary the distance between them, and this top plan view of the machine shown in Fig:

1, the belt-carrying members being at an angle to themandr'el and one of the presser lbelts being omitted, to avoid confusion in the disclosure of the parts; Fig. 3 is a transverse section through the machine ,and Fig.

Lf is a vertical longitudinal section through one of the pulley-carrying members.

In my improved machine I employ a table or bed 10,`m0unted in any suitable manner and serving to support the working parts of thev machine. At one end there is rigidl v mounted an upwardly-extending bracket or standard 11, and from the upper en'd of this standard, a mandrel 12 extends lengthwise of the machine above the bed or platform 10, and substantially parallel to the latter. Midway between the ends of the bed or platform, I mount a movable base 13, which inl connection withl the parts carried thereby, involves the main features of my invention. This base 13 is shown in Fig. 1 as extending lengthwise of thebed 10, and substantially parallel thereto, but in actual use of the machine the bed will occupy a position in a horizontal plane at an angle to the general direction of the bedjor frame, is illustrated in Fig. 2. The base rests upon a transversely extending supporting portion' 1.1 on the bed, and is free to swing around a vertically-extending sleeve 15 as a center. When the base is moved to the desired position, it may be locked in any suitable manner, as, for instance, by bolts 4S) carried by the bed and movable through curved slots in the base concentric with the center of the sleeve 15. This sleeve serves as a bearing for a vertical shaft 1G, extending up through the center of movement of the base, and at the lower end of this shaft are intermeshing bevel gears 17, by means of which the shaft receives motion from a main drive shaft 18. The latter is mounted in suitable eral length of the base, and in each groove l port for the shaft 22, and also for a vertical shaft 28, upon which is mounted a pulley .16 to the shaft 22, I employ any intermediate hangers and extends lengthwise of the maj chine and may be driven in any suitable manner.

Mounted upon the upper surface of the base 13 are two

guide blocks

19, 19, upon the upper surface of each of which is a dovetailed groove. The grooves extend parallel to each other, and-transversely of the genl there is mounted a slide 20 serving to carry the pulleys and presser belts and the driving mechanism therefor. As shown more particularly in Fig. 3, each slide has an upwardly-extending bracket or arm 21on one end thereof, and either Aintegral therewith or rigidly secured thereto. This arm serves to support one end of a shaft 22, extending lengthwise of themember 20 above the same and parallel thereto, and it also serves to support a vertical shaft upon which is mounted a pulley .23. Motion is transmit-ted from the shaft 22 to the pulley-bean ing shaft, by suitable intermeshing bevel gears 24. Upon the opposite end of the member 20 is an upwardly-extending bracket or arm 25, very similar to the arm or bracket 21, except that this bracket is mounted to move lengthwise of the member 20, as is indicated lparticularly in Fig. 4. The bracket has a dove-tailed groove in its under side, as shown in Fig. 1, and intol which extends a dove-tailed flange on the member 20. Ascrew bolt 26 extends lengthwise of the member 20 and has engagement with a dependin@r projection 27, so that the bracket 25 may be moved lengthwise of the member and held in any desired adjusted position. The bracket 25 serves as a sup` 29. Suitable intermeshing bevel gears 30 serve to transmit motion from the shaft 22 to the shaft 28 and its pulley.

For transmitting motion from the shaft shaft 31 extending lengthwise of the base 13 above the upper surface of the latter and at right angles to the two

shafts

22, 22. This shaft 3l is supported in a suitable bracket 32 carried by or constituting a part of the sleeve 15 and intermeshin gears 33 drive the shaft 31 from the sha t 16. The shaft 31 extends beneath each shaft 22 and carries two

worms

34, 34, which intermesh with worm wheels 35 on the shafts 22.' The shaft 31 is supported in suitable bearings 36 on the blocks 19, and the shafts 22 may be supported intermediate their ends vby suitable bearings 37, also mounted on the blocks 19. The worm wheels are keyed, so that they may slide lengthwise of their respective shafts'22, so that each sliding member with its shaft 22 and pulleys may move lengthwise in the supporting block 19, without interfering with the proper transmission of motion to the pulleys. Also, the bevel gear t 39e-on" the shaft 22 is keyed, so that the bracket 25 may be moved, and the worms 34 are keyed, so that they may move lengthwise of the shaft 3l. 'lo permit of this lastmentioned motion, each block 19 is provided with a dove-tailed flange on its under surface, to fit into a dove-tailed groove in the base, as is indicated particularly in Figs. 3 and 4. Two

screw bolts

38, 38 extend inwardly from the ends of the base'and engage in the blocks 19, so as to permit the latter to be moved toward or from each other, and thus, to, vary the distance'between the longitudinally

movable members

20, 20.

From the construction so far described, it will be seen that the base 13 is free to rotate about the shaft 16 as a center, and that it carries with it the shaft 31. The base 13 in swinging, swings the two

members

20, 20 simultaneously, and holds them in parallelism, and the swinging movement does not interfere with the free transmission of power to all of the pulleys. In order that during the swinging movement, the two pulleys of each member 20 will be kept substantially equidistant from the mandrel 12, which passes between them, the bed 10 is provided With two

grooves

39 and 40 in its upper surface adjacent opposite sides and. adjacent opposite ends.

One of the members 20 has a dependingA flange 41 carrying a roller 42 movable within the groove 40, and the other member carries a similar flange 43 'at its opposite end and on the lower end of this last-mentioned iange is a roller 44 in the groove 39. By the engagement of the rollers '42 and 44 in the two grooves, it will be seen that as the base 13 swings together with the members` tailed description is thought tobe unl necessary. f

In making a three-ply tube, two strips of paper A and B are fed through adjustable guides 45 and 4G of any suitable character, to the mandrel 12, and at an angle dependent upon thewidth of the strips. A belt '4T encirc'les the two pulleys 23 and 29 of tlu` first member 20, and one run of the belt passes one or more times around the freshly wound paper on the mandrel. serves to feed the paper lengthwise of the The belt l esima mandrel, and to firmly press the seco-nd layer upon the lirst, so that the adhesive between the two layers will properly permeate them and hold them together. The twoply tube. is fed along thegmandrel to a point adjacent the second member 20, where athird strip of paper C is fed through a suitable adjustable guide48. vA second belt, not shown in Fig. 2, but similar to the belt 4T, presses this third layer in place and feeds the tube ofthe free end of. the

` mandrel.

My improved machine is capable of universal adjustment and when adjusted, the parts are firmly held 1n position. The two belt-carrying

members

20, 20 remain inthat this point needs no particular attention. In adjusting the machine, it is only necessary to swing the basel?) to the desired angle', and in some'cases, 1t may be necessary to adjust the. blocks 19 toward or fromA each other, or to tighten or loosen the belts.

Having thus described my invention, I claim as new and desire to secure byLetters Patent:
