MACHINERY FOR THE MANUFACTURE OF NON-PASTED PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 508,505, dated November 14, 1893.

Application filed May 24, 1892. Serial No. 434,145. (No model.) Patented in England July 19, 1886, No. 9,368, and October 20,1991 No.17,991j in 1999, No. 386.

tained Letters Patent in Great Britain, No. 17,991, bearing date October 20, 1891;) and I do hereby declare that the following is a full,

7 clear, and exact description of the same.

My invention relates more especially to certain modifications and improvements in the principal parts of the machine for manufacturing paper tubes for cigarettes, the longitudinal edges of which are d raga pasted or gum'med together but are fol ed and interlocked one in the other, for which machinery patents were granted to me in Great Britain, No. 9,368, bearing date July 19, 1886 5 in Germany, No. 38,766, bearing date July 25,1886; in Switzerland, No. 386, of 1889, and in Canada, April 16, 1888, No. 28,917.

Figure 1 of the drawings is a front elevation of a machine constructed in accordance with my invention. Fig. 2 is a corresponding plan. Fig. 3 is a vertical transverse section taken on the line 1-2 of Fig. 2. Fig. i is a sectional elevation, of the part of the machine for the manufacture of the non-pasted tubes. Figs. 5 and 6 are separate views of the tube forming spindle, the former in partial sectional elevation, and the latter in plan. Fig.

Germany July 25, 1886, No. 38,766; in Canada April 16, 1888, No. 28,917, and in Switzerland,

Fig. 16. Fig. 18 shows, in elevation and plan, one of the lower bearings of the axis of the feed roller for the paper. Fig. 19 shows, in front and side elevation, the movable piece for fixing the cap of the bearings shown in Figs. 16 and 17.

The general arrangement of the machine is as follows, similar letters relating to like parts in all the figures of the drawings.

a is a table supported by the standard 01.. This table carries the parts composing the machine.

The driving shaft 0, which carries the pub leys 0' 0 and the'fly-wheel o drives, by

means of a pinion '0 the spur wheel 19 keyed on the shaft 1). The cam shaft 1) is placed above the table and turns in bearings b 5 the following cams are fixed on it; the cam g for feeding the paper, the cam h for operating the device h for pushing the empty tube onto the filling funnel, and the cam j for operating the printing stamp.

Manufacture of the paper tubes.At the end of the table a is placed a support 19 which is forked at its upper end and carries the axis ofthe loose pulley p on which is placed the bobbin of paper 19. The paper is unrolled by passing round the roller 0 mounted on the end of a tightening springp fixed to the end of a rigid arm 19 from the roller 19 the paper goes to another guide roller 10 from which it passes directly over the printing stamp j. A brake p with a pressure screw enables a suitable resistance to the unrolling of the paper to be produced. The paper on leaving the guide roller p passes through an opening in the support 7' of the counterpart j of the stamp; thence it passes to the heel of the long This spindle is suspended by the attachment q' in a kind of more or less pressure against the feed roller o. The upper side of the spindle rfor a great ally widens out and deepens, until at a dis-' tance of about three centimeters from the folder if it remains uniform at the bottom, but

the sides converge and come fair at theirends with those of the slit t of the folder if. The acting surface of a presser s bears in this groove by the actionof its spring supports 8', the pressure of which may be adjusted at pleasure. The groove 0" ends at the foldert which is let into the spindle r and consists of a piece of hard, close and fine grained metal; this piecet is perforated throughout its length with a conical hole 2?, the axis of which is inclined to that of the spindle r as shown. The metal at the top of this hole is slit through from end to end as shown at t. The hole t and the slit if end in a projecting beak t intended to conduct the folds of the paper right up to the small roller 0*. In my above-mentioned earlier machine this beak was not present and there was consequently a certain spaceleft between the end of the folder and the roller 0' in which space the folds of the paper became deformed and the effect of the pressing of goifering rollers o 1' upon such folds was rendered imperfect. The special shape of the groove r as shown, is extremely useful in order to cause the edges of the paper (Fig. 12) to turn inward. By the edges of the groove '1" coming fair with the slit t the abnormal separation of the folded edges of the paperattheirentranceinto theslittis avoided. Without this arrangement crumpling up and deformation of these edges of the paper at the entrance of the folder If frequently occur. Finally, as shown the spindle r carries a slot formed therein immediately in front of the folder if; the small roller 7' is free to revolve on its spindle in this slot and immediately behind the said fold er, and between it and the presser s is threaded freely on to the spindle 'r the shaper ring or former it. This latter device determines with rigorous exactitude the external diameter of the non-pasted pa per tube. Immediately over the roller r is mounted the feed roller *1), the axis of which rests in the special bearings 11 of two plumber blocks '0 '0 (See Figs. 16, 17, 18 and 19.) The bearings o are fixed to the plumber blocks by bolts passing through long slots which allow of raising or lowering these bearings to suit the diameter of the feed roller 0. In order to raise and lower equally the caps '0 of the plumber blocks, these caps are pivoted and hooked to nose pieces 42 which can be fixed adjustably on the plumber blocks. This simple and practical arrangement facilitates the change of the feed roller 1; whereby the feed can be altered so as to produce longer or shorter tubes. The paper passes through the tube former and is drawn forward by the rotation of the feeding roller 1: which presses on the loose roller 1' The rotation of the roller '2) is intermittent and is effected by a pinion m acted on by the rack 00 which is moved up and down vertically by a lever operated by the cam g; the pinion astransforms these up and down movements, by ratchet and pawl gear into an intermittent rotation in one j placed in the supportj direction of the roller 1). The amplitude of these rotations of the rollero correspond either to the total length that the cigarette is intended to have or preferably to half that length. It will now be understood that when the paper arrives at the heel of the spindle 'r it has already received a certain concavity of form which transforms it more or less into a complete cylinder in the frame q, see Fig. 14. Then the edges of the paper are brought together from the outside inward by the pressure of the presser s. The tube then assumes the internal diameter of the shaper ring 11. and afterward the edges engaging in the foldert are looked, folded, or rolled one in the other. On leaving the beak t of the folder If the longitudinal joint of the tube is closed, but the opposing pressure of the rollerso and T (one or both of which may be milled on the edge or not as may be preferred) completes the closing down of the folds. The non-pasted tube is thus completed. By altering the diameter of the loose shaper ring it the diameter of the tube may be varied.

Figs. 1, 2 and 4 show that the heel of the spindle r is some distance from the guide roller 19; this is to enable the paper to receive the impression of the printing or other stamp The stamp j is raised and lowered by the cam j placed on the shaft b. When the stamp descends, an inker placed at the end of a supporting rodj comesforward and inks the said stamp and then retires to allow of the ascent of this stamp. The rod 3' is moved horizontally to and fro by the action of the tube pusher h which is itself actuated by the cam h.

For the sake of clearness some of the parts and arrangements described in the specification of the above mentioned patents are herein described, but I desire to have it understood that I make no claim in this present specification to anything except improvements in the mechanism for forming the nonpasted tubes.

Having now described my invention, what I claim is- 1. In a machine for making non-pasted paper tubes, the combination with a tube-form-, ing spindle 1' provided with longitudinal groove 7" having diverging and converging sides, of aspring-actuated pressersadapted to bear on the paper above said groove, substantially as described and for the purposes set forth.

2. In a machine for making non-pasted paper tubes, the combination with the forming spindle 4" provided with longitudinal groove 1'' having diverging and converging sides of a folding device 25 arranged in the groove of said spindle, and provided with a slit t, and an inclined conical hole t of a beak t and the feed rollers v and 0*, all substantially as described and for the purposes set forth.

3. In a machine for making nonpasted parollers 12 and 1*, all substantially as described and for the purposes set forth.
