CIGARETTE-WRAPPING TUBE.

SPECIFICATION forming part of Letters Patent No. 739,935, dated September 29, 1903.

Application ledIebrnary 28,1901. Serial No. 49.278. (No model.)

To a/ZZ whom t may concern.-

Be it known that I, GASPAR SIMON, a citizen of the United States, residing at Jersey City,

' county of Hudson, and State of New Jersey,

have invented certain-new and useful lmprovements in Cigarette-Wrapping Tubes, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relatesto cigarette 1na-. chines of that class in which a continuous wrapping-strip is wrapped about a continuous filler-rod and the edges joined together to form a continuous cigarette-rod, which is afterward cut into lengths to form cigarettes; and the invention relates more particularly to that part of the machine commonly known as the wrapping-tube.

The invention aims generally to improve the construction of such wrapping-tubes, and especially to provide a tube so constructed that parts likely to wear out in use or which for other reasons need to be renewed or re placed by other parts may be readily removed and replaced and that such parts may be inexpensively made and also to provide for the ready adjustment of parts, so as to secure the best work and to permit convenient access to parts of the tube for cleaning.

A full understanding of the invention can best be given by a detailed description of a preferred construction embodying the same, and such a description will now be given in connection with the accompanying drawings, showing such a preferred construction.

Figure 1 shows in side elevation so much of a cigarette-machine embodying my invention as is necessary to an understanding thereof. Fig. 2 is a plan View of the parts shown in Fig. 1. Fig. 3isfa longitudinal sectional view ofthe wrapping-tube. Figs. 4, A5, 6, 7, 8, and 9 are cross-sectional views taken, respectively, on

lines

4, 5, 6, 7, 8, and 9 of Fig. 3. Fig. '10 is a detail illustrating a slight modification; and Figs. 11 and'12 are cross-sectional views taken, respectively, on lines 11 and 12 of Fig. 10.

Referring to'the drawings, the tobacco is advanced to the wrapping-tube in Vthe form 5o of a continuous filler-rod from feeding devices comprising side belts 10, turning about Vwheels 11, a bottom belt 12, turning about wheel 13, and a compressing-disk 14. The tobacco rod is advanced, by these or other suitable feeding devices between side guides 15 of a bridge or throat-piece 16, to the trough-like entrance of the wrapping-tube A,

Where it comes onto the Wrapping-strip n by' which the wrapping operations are directly performed-and a permanent supporting part by which the various parts'of the wrapping-tube proper are carried. This supporting part or casing 25 may be of any suitable construction, but is preferably formed "of a solid metal table or bar having a groove extending longitudinally thereof, in which the wrapping-tube proper is set. This supporting-casing may thus be Vmade of sufficient weight to give rigidity and strength to the whole structure and properly support the parts of the wrapping-tube in operative position and enable them to resist the strains incident to theoperation of the machine. The

casing 25 may be supported in any suitable manner, but is preferably formed With'depending

lugs

26 and 27, by which'it is secured to the frame of the machine, as by means of

brackets

28 and 29. g

The Wrapping-tube proper is preferably formed of sheet metal and may be divided roughly into a troughlike entrance portion B, a compressing portion C, and a wrapping and sealing portion D. As here shown and IOO separately from the rest of the tube or to forming the portions C and D or parts thereof in one piece. The portion B consists of a tapering trough 30 of substantially fiat cross-section at theentrance end, as shown in Fig. 4, and becoming gradually of curved cross-section, as shown by Figs. 5 and 6, until it is substantially semicircular in crosssection at the farther end, and its edges are provided with inwardly-extending guidingflanges 3. The groove of the casing 25 at and near the entrance or front end of the casing is of a form corresponding to the trough 30, and the trough 30 is secured removably in place inthe groove of the casing, as by means of clips 31. The feeding-belt 2v and the wrapper-strip .fr as they pass through this section of the wrapping-tube will have their edges gradually bent upward on either side of the filler-rod.

The compressing portion C of the tube is of tapering form and is formed bya tapering trough 35, forming the bottom and sides of this portion of the tube, and a cover portion or compressing-tongue 36, by which the tobacco is compressed as it is advanced between the upturned edges of the wrapper. This tongue 36 is preferably curved in crossseetion and tapered and is of such width as to leave sufficient space between its edges and the side walls of the trough 35 to form guiding-slots for the edges of the belt 2 and Wrapper It may be supported in any suitable manner to avoid interference with the edges of the wrapper and belt, but is preferably adjustably suspended from the casing 25 by means of an arm 37 extending upward from the tongue and secured to a bracket 38 ou the casing` 25 by means of adjusting-

screws

39 and 40, whereby the tongue may be readily adjusted vertically. In passing through the portion C of the tube the edges of the wrapper will be turned still farther upward, and the tobacco will be compressed, so as to permit the edges of the wrapper to be turned down and lapped over the top thereof in their further progress through the tube.

The wrapping and sealing portion D of the tube is formed of a trough portion 45, forming the bottom and sides of this portion of the tube and preferably formed integral with the tapering trough 35 of the portion C. One edge of the trough 45 is extended upward to form a curved deflecting-flange 46, extending from and beyond the end of the compressing-` tended to form a deflector 49, by which the pasted edge of the wrapper is turned over-the edge which has been previously turned down over the tobacco. The pasted Yedge of the wrapper is then further deflected and pressed down into contact with the other edge of the wrapper by passing under the end of a pressing-flange 50, the wrapper-tube being thus closed and sealed about the tobacco rod, the opposite 4flange 46 being cut away to permit this folding down of the pasted edge of the wrapper. After the edges of the wrapper are thus brought together they are held in contact by pressure of the flange 50 as the cigarette-rod thus form-ed passes onward beneath this flange. The continuous cigarette-rod thus formed may be cut into proper cigarette lengths by any suitable mechanism, as usual in this class ofA machines.

The flange 50 is preferably formed separate from the trough-like portion 45 of the tube and carried by an arm 55, forming a part of the casing 25, but formed separately from the main portion of the casing and removably secured thereto, as by means of a pivoted screwrod and thumb-nut 56. The flange 50 may thus be readily removed to permit access to the interior of this portion of the tube, as is often desirable for the purpose of' cleaning o paste which accumulates thereon from the pasted wrapper.

The groove in the parts of the casing 25, which support the portions C and D of the tube, is shaped to conform to the bottom and sides of the trough-like parts 35 and 45 of the tube, and the casing is provided with suitable means for securing and holding the tube in place. For this purpose a portion of one side of the casing is removably ysecured to the main portion of the easing, so that it may be moved into and out of position to clamp the tube in the groove of the casing. This movable or clamping portion of the casing is preferably formed by that part of the' casing which engages that part of the side of the tube which carries the deectiug-llange 46, and it is preferably provided with a flange 6l to extend over and bear on the flange 46 of the tube, this flange 61 being partly cut away, as shown best in Figs. 2 and 8, so as not to interfere with the pasting-disk 48. Any suitf ICO IIC

the pins may be moved to draw t-he clamptube is in position in the casing it Willbe supported throughoutits length and in such a Way as to be strengthened by the casing, and thus rendered capable of withstanding strains, though itself of such comparatively light material that it Would not be capable of Withstanding such strains if unsupported.

It is desirable to provide for the relative j lateral adjustment of the belt 2 and Wrapper of a spring 79 to as they enter the trough 30. For this purpose a guide-sleeve is provided for the belt near the roller17, this guide-sleeve being carried by a frame 7l, secured to the under side of the casing 25 and adjustable laterally by 74, by which it may be turned and the frame 7l and guide 70 thus caused to move laterally in either direction.

Instead of the screw-rod 72 a sliding rod 75 might be provided, to which the frame 7l is secured and which is mounted to slide through openings in the ears 73, as shown in Figs. 10 and 12. In connection with such rod I preferably provide a pivoted finger 76,v

adapted to enter any one of a series of openings 77 therein for the purpose of holding it and the frame 71 in the position of lateral adjustment to which they have been moved.

The iinger 76 may be carried by a rod 78, mounted in the ears 73, and under tension move the finger 76 into holding position. y

It is sometimes desirable to provide for the adjustment of both the belt and the Wrapper, and I have shown a construction for accomplishing this purpose in the main figures. As shown in these flgures,'a frame 8O is secured to the casing 25 so as to be also laterally adjustable, as by means of a screw-rod 81, passing through a threaded openingin the frame and carried by the ears 73 and having a milled head 82, by Wh-ich it may be turned. This frame 8O has tWo ears 83, which engage the guide-roll 17, so that as the frame is moved laterally the guide-roll Will be correspond ingly moved. The frame SO also preferably carries a guide 84, through which the Wrappenpassesbefore reaching the guide-roll 17.

It will be noticed, fu rther', that my construction of tube, as shown inthe drawings, permits an endless feeding-belt 2 to be threaded through the tube, thus avoiding the necessity of joining the ends of the' belt after it has been passed throughV the tube. Considerable difficulty has heretofore been experienced in the use of metal tubes of the general form of that which I have shown, both by reason of the trouble and expense involved in afterward joining the ends of the belt and on account of the bunch in the belt caused by the overlapping of the ends when` joined in the customary manner.

The bridge or throat-piece 16 is supported and positioned at one end by means of laterally-extending pins 90, Which enter slots 91, formed in the sides of the casing 25 near the entrance end of the trough-like portion 30 of the tube, and its other end rests on the bottom feeding-belt 12, as shown in Figs. 1 and 2, and it is held in position and partlyv supported by means of spring-arms 92.

It Will be understood that I am not to be limited to the exact construction and arrangement of parts as shown in the drawings, but that the invention includes modifications and changes therein Within the claims.
