CIGARETTE-MACHINE.

u SPECIFICATION forming part of Letters Patent No. 406,611, dated July 9, 1889.

Application led November 26, 1887. Serial No. 256,218. (No model.)

To all whom t may concern.-

Be it known that I, OSCAR WV. ALLISON, of the city of Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Cigarette- Machines, of which the following is a specification.

This invention relates to that class of cigarettemachines by which the tobacco is formed into a rod or bar around which is wrapped a strip or web of paper suitably4 pasted or gunnned, which covered rod or bar is finally cut up into cigarettes of the desired length.

The object of my invention is to improve the various devices-such as the feeding, rod forming and compressing, paper folding and pasting, carrying and cutting devices-which enter into the organization of the machine.

The invention consists, to th ese ends, of the improvements, which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, consisting of three sheets, Figure 1 is a front elevation of the feed mechanism. Fig. 2 is a top plan view of the machine. Fig. 3 is a side eleva* tion of the pasting mechanism and connecting parts. Fig. 4 is a top plan View thereof. Fig. 5 is a cross-section of the grooved endless band which receives the tobacco and the compressingband running in the same. Fig.

`G is a sectional elevation, on an enlarged scale, showing the receiving-band opened by the inclined pulleys preparatory to receiving the tobacco. ing the receiving-band opened by the wedgefaced wheel. Fig. 8 is a side elevation of the machine. Fig. 9 is a top plan view of the endless receiving-band and connecting parts. Fig. 10 is a crosssection of the drawing mechanism. Fig. 11 is a side elevation of the cutter mechanism. Fig. 12 is a-top plan view of the same. Fig. 13 is a longitudinal vertical sect-ion of the picker mechanism. Fig. 14 is a longitudinal section of the paper-guiding mechanism. Fig. 15 represents an end view of the pasti-ng mechanism. Figs. 16 and 17 represent the pressure-roller and drawingbelts, on an enlarged scale, in plan and side elevation. p

Like letters of reference refer to like parts in the several figures.

Fig. 7 is a cross-section, show- A represents the horizontal bed orframe of the machine, which is supported by legs a., and A is the main driving-shaft journaled in bearings attached to said frame.`

B is the feed-table upon which the tobacco is placed and which is arranged, above the bed and on one side thereof in any suitable manner. A

b represents the endless feed-apron arranged with Vits upper portion transversely on the tableB and extending over the frame A.

b represents t-he transverse trough or frame in which the feedapron is arranged.

C is the horizontal picker-wheel or toothed cylinder arranged opposite the inner end of the feed-apron b and provided with suitable teeth which pick the tobacco off the end of said apron.

c is the pressure-roller bearing upon` the apron l) and the roller c', around which it 4passes opposite the picker-cylinder C, and whereby the movement of the tobacco is retarded at the discharge end of the apron, so as to enable the picker-wheel to loosen and separate the shreds or strands of tobacco more eifectually.

C"represents a similar picker-wheel ar-I ranged below the picker C and receiving the tobacco from the latter. This vlower pickertobacco which are not detached by the upper picker-wheel. The picker-wheels C C are inclosed by a casing C2, the vertical inner wall c2 of which `forms a throat c3, in which the lower picker C is arranged. The latter contracts the throat c3 and facilitates the delivery of the tobacco from the feeder, and re'- moves any tobacco which may adhere tothe lower returning portion of the feed-apron.

The roller c', around which the feed-apron b runs, is provided with a gear-wheel b2, which is driven by a worm h3, mounted on a shaft b4. The latter receives motion from a large pulley 195, mounted on the main shaft A', by a pulley h6 and driving-belt 197; The pressureroller c is provided with a gear-wheel c4, which meshes with the gear-wheel b2. The shaft of the upper picker C is driven from the shaft b4 by a belt c5, running around pulleys c c7, and a guide-roller cs. The lower picker-cylinder is driven from the upper picker-cylinder by a belt c. Y

Wheel serves to pick off any long strands of IOO D represents an endless grooved band, of rubber or other flexible material, which is arranged longitudinally over the main frameA andpasses horizontally underneath th e throat c3 of the feed mechanism and receives the tobacco therefrom. The endless compressingband D isprovided with alongitudinal raised rib d, which is provided with a longitudinal groove d. The receiving-band D runs underneath the feed mechanism around a pulley E, having a wedge-shaped face. As the band passes over this pulley, its base-flanges d2 are drawn downwardly over the wedge on the face of the pulley, whereby the groove in the band is distended,'as represented in Figs. 6 and 7, and enabled to receive the tobacco.

F F represent two inclined flat-faced pulleys arranged on opposite sides of the endless band D, rearwardly of the pulley E, and bearing against the upper sides of the base-anges d2 of the band. The pulleys F F serve to hold the band in an open or distended position in rear of the pulley E, and they are ar.- ranged at such a distance from the pulley E as to keep open a portion of ther groove d about equal to the width of the feed-throat c3. The tobacco is fed into the groove of the band by the picker-wheel C as the band passes under the throat c3 in this open condition. The inclined pulleys F F are mounted at the upper ends of standards ff.

G represents a fiat-faced roller,which bears against the under side of the grooved band in rear of the inclined rollers F F. As t-he band passes over thestraight-faced roller G, its baseefianges d2 are straightened or caused to assume their normal position and the sides of the groove d are thereby caused to approach each other and assume their former parallel position, thereby contracting the groove d to its original or normal size. This contraction or straightening of the band compacts the tobacco in a measure.

g is a compressor-wheel arranged in rear of the roller G, and has a concave face which runs in the groove d of the band D, as represented in Figs. S and 9, whereby the tobacco is further compacted in the groove of the band. The compressor-wheel g is journaled in the upper end of supports or columns g. The receiving-band D runs around a flatfaced pulley E', arranged over the front end of the main frame A. The pulley E is journaled in the upper ends of standards e, and the wheel E is mounted in standards c. The shaft of the pulley E is provided with a gearpinion e2, which meshes with a gear-wheel e3, and the latter in turn engages with a pinion e4, Fig. 10, secured to the main driving-shaft A. In this manner the compressing-bandD is driven from the main shaft. The base portion d2 of the band D is preferably stiffened by a layer of canvas or other fabric d3, as represented in Figs. 5, 6, and 7. The partiallycompacted rod of tobacco is now carried along by the endless band D, and is further compacted by an endless pressure-band H, which runs around suitable pulleys h h h2. The band H Yruns in the groove d of the band D at the point where the latter runs around the pulley E', and also along the under side of the band D to the pulley h', Where it leaves the band D and runs around the pulley h2, thence` back to the pulley 7i, as represented in Fig. 8. In passing around the pulley E outside of band D the band H is tightly drawn into the groove of the band D, and exerts a sufficient pressure upon the tobacco in the groove to compact the same into a round orV cylindrical rod. The inner face of the band H is made concave and the bottom of the groove d in the band D is also made concave, so that the depression of the compressing-band l-l and the groove in the band D together form a cylindrical mold, as represented in Fig. 5. The compressing-band H is driven by frictional' contact with the band D. The rod of tobacco issues from the compressing-bands D H, beyond the pulleys 7i and E, and is guided by a downwardly-inclined trough or chute i to the drawing mechanism. The end of the chute t', which receives the tobacco rod or filler, is preferably flared outward to facilitate the entrance of the rod, as indicated in Fig. 17. This drawing mechanism consists of two endless horizontal drawing belts or bands J J, which are arranged side by side upon a supplementary table K, supported above the bed A, and which run around suitable pulleys ,7' jf j2j3. The belts J J are grooved or recessed in their outer faces, so that the inner portionsof the two belts, which run in contact with Veach other, will form a longitudinal groove y, open at the top, which receives the rod of tobacco and the paper wrapper inclosing the same.

j represents a pressure-roller, whereby the rod of tobacco is held down in the groove j* as it comes from the chute c'. The roller js is supported in any suitable manner, so that its IIO lower side bears on the tobacco-rod passing beneath it, being located a short distance behind the point whererthc belts J J meet, as indicated in Fig. 2, or, preferably, with its center immediately above suoli point, as represented in Fig. 17. The lowerside of the roller passes between the edges of the paper, one of which is folded down by the folder M and the other by the brush S. The operation of the' folder M may be assisted by a finger M, which partially folds down the edge of the paper before it arrives at folder M. 'f

j represents two longitudinal angle irons or strips, which are secured to the top of the supplementary table K and bear against the outer sides of the contiguous portions of the grooved belts J J, so as to prevent the same from yielding laterally under thepressure of the continuous cigarette moving between said belts.

The pulleys j j j? j, around which the bands J J run, are mounted upon vertical shafts 7c 7c', and the shafts 7c are provided with gear-wheels 702 k2, meshing with each other. One of the shafts k' is provided with a bevel-wheel 7c3, which meshes with a bevelpinion h4, secured to the main driving-shaft A'.

By constructing the driving mechanism as above described the groove between the two drawing-belts is divided into two parts which approach each other at the receiving end of the groove and form a converging space Whereby the entrance of the rod of tobacco into the groove is facilitated, and the discharge of the rod from the groove is likewise facilitated by the two parts of the groove receding from each other at the delivery end of the drawing mechanism.

Heret-ofore it has been proposed to use printing devices for forming an imprint on the paper wrapper of the cigarette; but this has proved impracticable, because the drawing devices heretofore used were not sufficiently positive in their operation and would allow the cigarette to slip and cause the imprint to get out of register with the cutter mechanism, thereby frequently cutting the imprint in two. Myimproved drawing mechanism is sufficiently positive in its action to prevent the slipping of the cigarette and thereby overcomes this objection.

L represents a drum arranged below the bed A and upon which the web of paper is wound. From the drum L the paper passes through a printing mechanism L', of any suitable construction, whereby a suitable imprint is formed upon the paper, such as a trademark` or the name of the manufacturer. The web of paper thence passes upwardly around three guide-rollers Z Z Z2, which hold the paper against lateral displacement and present it properly to the folding mechanism arranged upon the supplementary table K, near the front portions of the drawing-belts J J. This folding mechanism may be of any suitable or well-known construction, but is preferably composed of a curved concave guide m and a folding-plate M. The guide m conducts the web of paper into the groove j, between the drawing-belts J J, and the trough or chute t' conducts the rod of tobacco into said groove upon the web of paper. The folding-plate M is arranged above the front portion of the drawing-belts J J ,in rear of the pressure-roller 3'5, and is provided with a curved or inclined front edge m' which folds one of the projecting aps of the paper down upon the rod of tobacco, as represented in Figs. 3 and 16.

n represents a rotating wiper1 or brush arranged opposite the folder-plate M, and Whereby paste is applied to the other projecting N, as represented in ligs. 2, 3, and 4.

upon the paste-wheel N', when the reciprocating frame N3 has moved inward and supplies the latter with paste from the table N2. The reciprocating frame N3 is actuated by a rock-arm O and a rod o, and the rock-arm O is actuated in turn by a pin o', secured to a pulley p and engaging in a slot in the rockarm. The pulley p is mounted upon a hori- Zontal shaft p', and is rotated from a horizontal counter-shaft p2 by a belt p3 and a pulley p4, mounted on the shaft p2. The latter receives motion from a short shaft q, by me'ans of bevel-wheels q', and the shaft q in turn is rotated from the gear-wheel e3 by a pinion q2, meshing with the latter. The paste-wheel N receives an intermittent rotary motion by means of a pivoted arm n3, which rests loosely against the front end of the reciprocating frame N3, and a pawl n4, pivoted to the rockarm n3, engaging with the ratchet-wheel n", secured to the wheel N' n is a spring secured -with one end to the arm n3 and with its other end to the casing N, and whereby the arm 'n3 is drawn backwardly at the backward stroke of the reciprocating frame. By this means the paste-wheel N' is intermittingly rotated, whereby fresh portions of the wheel are constantly presented to the rotary wiper n. The latter receives motion from the shaft p by an endless belt r, running around pulleys r r2, mounted respectively upon the shaft of the wiper and the shaft p'. The wiper n is flexible, and it comes in contact with the roller N' at each revolution, receiving the paste therefrom and transferring it to the edge of the paper.

' `S represents a rotating brush arranged obliquely in rear of the folding and pasting mechanism, and whereby the pasted iiap of been previously folded down upon the rod of tobacco. The rotating brush is mounted in suitable bearings formed in a standard s, and is driven from the shaft p2 by an endless belt s', running around pulleys s2 S3, mounted on the shaft of the brush andthe shaft p2, and the guide-wheel s4. S' represents a similar rotating brush arranged in rear of the brush S, and whereby any wrinkles which may occur in the folded and pasted paper are smoothed out. The brush S' is rotated from the shaft p2 in a manner similar to the brush S. t

T represents a rotating cutter-disk to which the continuous 'cigarette is carried by the drawing mechanism, and whereby the cigarette is cut into suitable lengths. This cutterdisk is supported in such manner that it can be moved toward and from the continuous cigarette, and at the same time in the direction in vwhich the cigarette moves. The mandrel t of the cutter-disk T is mounted in a sliding carriage t', which moves in longitudinal ways formed on an arm t2. j The latter is mounted upon a vertical pivot t3, secured to the frame of the machine, s0 that the arln, with the cutter-disk, can swing upon said pivot IOO `paper is laid down upon the iiap which has IIO in the direction in which the endless cigarette moves.

t4 represents a rotating cam mounted upon the shaft p2, and which bears against the carclined, as shown in Fig. l2, so as to move the arm and cutter-disk in the direction in which the cigarette moves simultaneously with the forward movement of thecutter-carriage. The inclination of the side ofthe rotating cam is such as to cause the cutter-disk to move with the same speed as the cigarette, and thereby effect a perfect cut. The swinging arm t2 is returned to its former position, preparatory to forming a new cut, by a flat spring t6, secured to the frame of the machine and bearing with its upper end against the arm t2.

u represents a die arranged at theinner end of the arm t2, and through which' the endless cigarette moves, and across which the cutter-disk passes in producing the cut. The cutter-disk is rotated by means of a belt QJ, passing around a pulley o', arranged on the shaft p2, thence around a pulley o2, mounted in the lower end ot' an arm V, thence upwardly to a pulley @3, mounted on the mandrel t of the cutter-disk, thence downwardly to another pulley v4, arranged on one side of the pulley r2, and thence back to the pulley o. The arm V is mounted loosely with its upper end upon the shaft p2, and its lower end is connected with the mandrel of the cutter-disk by an arm V', so that the pulleys o2 and 'U4 and belt o can take part in the reciprocating movements of the cutter-disk and rotate the same continuously.

It is obvious that the tobacco-feeding mechanism for cigarette machines herein described, by which the tobacco is delivered in a continuous manner in a condition for the production of a compacted tobacco-filler, may be employed in connection with any other suitable filler-forming devices or any suitable mechanism adapted to inclose and seal the filler within a paper wrapper.
