bring the end of said tube against the inner face of the die for the purpose of ecting the tube when the arbor retreats: 12 is an enlarged detail front elevation of the tubesizing die and chuck for holding same: Fig.

13is an enlarged cross sectional view of the tube-sizing die, its chuck, and hollow spindle on which said chuck is mounted: 14*is an enlarged broken view of one of the tubearbors and tube thereon, side elevation of spring actuated slides adapted to be opened by the forward end of a tube-arbor to permit the end of the tube to engage the face of said slides to force said tube on to the arbor: Fig.

15is an enlarged detail front elevation of the spring actuating slides shown at Fig. 14: Fig. 16is an enlarged rear end elevation of the arbor carrying slide; tube-arbor carrying shaft and its dial; dial actuating pawl and its slide, broken view of the pin adapted to carry a roll on its forward end to engage one of the cam-grooves in said shaft, and broken View of the operating-lever for said pin: Fig. 17is an enlarged detail plan view of the arm for tilting the pawl connected with the dial of the tube-arbor shaft.

Its construction and operation are as follows:

1 represents the bed of the machine. 2 is a slide adapted to be longitudinally reciprocated thereon.

3, Figs. 12, is the driving-shaft journaled in the bearings 4. is the drivingpulley mounted on one end of this shaft, and 6 is a pinion mounted on the other end to register with and rotate the large gear 7 mounted on the cross-shaft 8.

9 is a cam-shaft on the op osite side of the machine which is rotatec through the medium of its bevel-gear registering with the bevel-gear 11 of said cross-shaft.

The slide 2 is reciprocated by means of the pinion 12 on the shaft 13, F ig. 6, alternately engaging with the internal segmental teeth 14 and formed on the large gear 7. This shaft 13 is journal ed in the bearing 16, shown at Figs. 2 and 3. 17 is a pinion on the inner end of this shaft registering with the rack 18 on the underside of the slide 2, see also Figs. 1 and 3.

Referring to Fig. 6, the gear 7 runs continuously in the direction shown by the arrow, and pinion 12 is just being engaged by the teeth 14 for a forward movement of the arbor carrying slide.

19 and 20 are pins projecting laterally from the inner vertical face of the pinion 12 so that, when the teeth 14 have passed by the said pinion, one of these pins will engage with the cam 21 to reverse the rotation of said pinion in order that it may properly register with the outer series of teeth 15 on the gear 7. By the time that the pin engaging the cam 21 has passed through said cam, the other or opposite pin will engage the cam 22. In traversing from cam 21 to cam 22, the rotation of the pinion will cease temporarily and, consequently, the slide will be ha ted in its advanced position for the purpose presently to be described. The throw of the cam 22 is such that the rotary travel is increased to correspond with the travel of the teeth 15 so that there will be no shock when said teeth enga e the inion for a reverse movement of the slide. hen, therefore, the cam 23 engages one of the pinion pins, its rotary motion is again reversed in readiness to be engaged by the teeth 14, and the cam 24 will time the rotary travel of the pinion to agree with the speed of said teeth.

25, Figs. 2, 3 and 5, is a standard secured to the forward end of the slide 2, and, in said standard, is journaled the shaft 26. 27 is a head mounted on the forward end of this shaft carrying the tube- arbors 28 and 29.

30, Figs. 2, 4, 12 and 13, is the die-head carrying the sizing-die 31, and it is mounted on the hollow spindle 32 journaled in the uprights 33. 34 is a pulley mounted upon said spindle to give it a rotary movement independent of the rotary movement of the driving-shaft 3, previously mentioned.

35 is a hopper for holding the unsized tubes 36, Fig. 4, which hopper is supported on the bracket 37 projecting from the machine-bed. 37 see also Fig. 2, are projections of said bracket in which is journaled the short shaft 38, on which is mounted the tube carrying flanges 39 having the grooves 40 adapted to receive the unsized tubes in the hopper and carry them outside in line with one of the tubearbors, for the purpose presently to be explained. The shaft 38, with its tube carrying flanges 39, is intermittently rotated through the medium of the ratchet-wheel 41 mounted on said shaft and the lever 42 journaled on the drivingshaft 3, the up er end of which lever carries the pawl 43 acfapted to engage the teethof said ratchet-wheel. 44 is a vertical rod actuated by the spring 45 to maintain the engagement of the awl 43 with the said ratchet-wheel. The ever 42 is actuated by the forked-lever 46 carrying the roll 47 adapted to engage with the cam-groove 48 of the disk 49 mounted on the cam-shaft 9.

The enlarged portion 26*, Fig. 5, of the arbor carrying shaft 26 is provided, see also Figs. 1, 2, 3, 8, 9 and 16, with cam- grooves 50 and 51 adapted'to be alternately engaged by the roll 52, Fig. 5, and thus rotate said shaft one-half of a revolution for the purpose presently to be described. This roll is mounted on the end of the reciprocating-pin 53 operatively mounted in the standard 54 mountee on the rear end of the machine-bed 1. This pin is pivotally connected to the upper enc of the lever 55, the lower end of which lever carries, Fig. 3, the roll 56 to engage the cam 57 mounted on the shaft 9.

The central portion of said lever is pivotally.

supported on the body portion of the screw 58.

60 is a dial carried by the shaft 26, and 61 are notches in its periphery adapted to be alternately engaged by the pawl 62 pivotally supported on the screw 63 projecting from the slide 64, which slide is operatively mounted in a part of the standard 25. 65 is a pin in the outer end of this slide carrying the roll 66 adapted to travel in the groove. or channel-way 67 on the upper surface of the frame 68., as shown at Figs. 8 and 9. This frame is mounted on the rock-shaft 69, seen more clearly in Fig. 1, which shaft is journaled in the bearings 70 secured to the machine-bed, 71 is an arm secured to this shaft and carries at its lower end the roll 72 adapted to engage a cam-groove, not shown, in the vertical face of the disk 73 mounted on the shaft 9 so that, through the medium of said cam, the shaft 69 is oscillated to move the frame 68 to and from the bed of the ma chine for the purpose to be hereinafter more fully described.

74, Figs. 1, 3, 16 and 17, is an arm whose shoulder is pivotally supported by one end to the lever 55 While the forearm, see also Figs. 2, 5, 8 and 9, is adapted to rest on the gib 75 and be moved forward toengage the outer end 62 of the pawl 62 and carry the forward end of said pawl out of engagement with the dial 60, and, when disengaged therefrom, said pawl will be rengaged with the lowest notch of said dial by means of the spring 76 shown at Figs. 8 and 9.

Operation: In Fig.2, the slide is in the act of moving forward with the arbor 28 empty, and the arbor 29 carrying the unsized tube 36. In the meantime, the tube carrying flanges 39 have brought the tube 36 directly in the path of the approaching arbor 28 so that, while the sizing die is engaged With the tube on the arbor 29, the arbor 28 will enter the tube 36*, passing entirely through the same. Back of this tube are, see also Figs. 14 and 15, the two vertical slides 77 and 78, which slides operate in the guide-way 79 of the bracket 80. The inner ends of these slides are slightly concaved to form the opening 81 shown at Fig. 15. The forward end of the tube 36 will lie in close proximity to the outer faces of these slides so that, when the arbor 28 enters said-tube, these slides will act as a kicking-post to force the tube on to the arbor. To insure the tube being forced on to the arbor far enough, and also to prevent the end of the arbor striking against a solid body, the rounded end of the arbor will enter the opening 81 and force the slides 77 and 78 back against the tension of their springs 82 and 83, and thus permit the end of the arbor to pass between said slides While the end of the tube is still in pushing contact therewith. WVhen, therefore, a tube from the hopper has been forced on to one of the arbors, the tube on the other arbor will have been sized by contact with the rapidly rotating die 31.

The finished tube is stripped from its arbor in the following manner: That portion of the arbor which supports the paper tube is, of course, the same in diameter as the internal diameter of the tube, or, at least, near enough to said internal diameter to insure a close fit, while that portion of the arbor not adapted to enter the tube is larger in order to form the shoulder A, Figs. 7 and 11, to serve as a kicking-post against the action of the sizing-die, or, in other words, as a means for pushing the tube through the sizing-die. The lower portion of this enlarged part of the arbor is cut away as shown at B, which cut-away portion is on a line with the arbor proper.

After the tube has-passed through the sizing-die, the slide 2 will continue to advance so as to carry the rear end of the sized tube just beyond the inner straight face. 31 of the sizing-die. While this extra forward movement is taking place, the rock-shaft 69 will be actuated by its cam to throw the frame 68 slightly toward the machine, and by reason of the engagement of the slide 6 1, Fig. 9, with this frame, as before mentioned, the said slide will be carried inward with said frame sufficient to rotate the arbor 26 and thus throw the tube-arbors slightly out of horizontal alinement with each other as represented by the diagram shown at Fig. 10, wherein the dotted line C represents the line on which the centers of the two arbors would lie before being tilted. This slight tilt of the arbors will, see Fig. 11, also throw the arbor in the sizing-die out of center with said die with the cut-away portion B of the arbor resting on the lower surface of the die. This will bring the lower edge of the finished tube against the inner straight face of the sizingdie and thus hold the tube while the arbor is withdrawn therefrom by the now retreating slide 2.

hen the slide 2 has retreated far enough to insure the removal of the sized tube, the slide 64 will be carried out so as to level up the arbors, or, in other words, bring them into the same horizontal alinement they occupied previous to the tilting movement before described. Immediately after this movement, the lever 55 will be actuated forward to place the roll 52 in the path of one of the cam- grooves 50 or 51, as the case may be, and, also, the arm 74 in the path of the outer end. 62 of the pawl 62. the pawl will ride up on the arm 74, see Fig. 8, to disengage the forward end of said pawl with the dial 60, so as to leave the arbor earrying shaft free to make one-half of a revolution when one of the cam-grooves engage with the roll 52, Fig. 5. This movement will have rotated the tube carrying arbors to bring the one, on whichatubehas been forced, in line with the sizing-die, and the empty arbor in position to receive a fresh unsized tube. When the slide starts forward, the lever 55 is retreated to carry the roll 52 out of the cam-groove in the arbor carrying shaft, and the arm 74 from under the outer end of the pawl 62 so as to let said pawl reengage with the lowest notch in the dial 60, as seen at Fig. 16.

At theinner end of each of the cam grooves 50 and 51 of the shaft 26, is a straight portion to serve as a standstill to enable the roll 52 to be fully retreated when the slide 2 begins its forward movement. One of these standstill portions, 84, is shown at Fig. 1.
