SPECIFICATION forming part of Letters Patent No. 590,629, dated September 28, 1897. Application filed fleptember 5, 1896. serial No. 604,992. (No model.)

To all whom, it may concern:

citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Cigarette-Machines, of which the following is a specification.

This invention relates to cigarette machines, and especially to machines of this class adapted for forming a continuous cigarette-body from a suitably-wrapped continuous filler-rod and for severing said body into short lengths to produce cigarettes.

My present invention is especially designed and intended as an improvement upon-that shown-and-described in Patent No. 572,375,

granted to me December],1896, and many of the features disclosed therein are embodied in the machine which will be herein described and illustrated.

The machine described in my patent above referred to and that represented in my prescut application are both provided with means for forming a continuous filler-rod or tobacco rod from loose tobacco, which may be fed into the machine in any desired manner, and for subsequently wrapping around the filler-rod a suitable endless wrapper-strip while the filler-rod and the wrapper are continuously.

advancing through the machine, and both also have means for pasting the outer edge of the wrapper before it is wound around thefiller-rod and cutting means for severing the cigarette-body into single cigarette lengths.

One of the objects of my presentinvention is to provide improved feeding devices for supplying loose tobacco to the machine and for shaping the same into a tobacco rod of approximately cylindrical form before the latter is acted upon by the former-rolls, with which the filler and wrapper conveyers, usually in the form of an endless belt or belts, cooperate.

Another object of the invention is to provide a pair of belts by means of which the movements of the filler and the wrapper may be separately controlled and whereby also the filler may be fed to the former-rolls somewhat faster than the wrapper is supplied for wrappin g around the tobacco rod, this organization of the parts permitting the wrapper to be wound much m ore tightly around the fillerrod than it is possible to do with a single Beit known that I, FRANCIS H. RICHARDS, a

1 tion with a pair of separately-operative belts,

one controlling the movements of the filler and the other of the wrapper, I also find it advantageous to employ a wrapperguide and a filler-shaper between the two belts and at the point where the tobacco rod passes off from its belt and onto the wrapper carried by the wrapper-belt, these devices being preferably combined and so formed as to not only guide the filler and the wrapper in their nnovements, but also to shape the same into a perfect cylindrical form as the wrapper goes onto the tobaccorod.

Another important object of this invention is to furnish improved and simple means for feeding the wrapper-strip and holding the same firmly against the wrapper-conveying belt, so as to prevent slipping of the strip in advancing toward the filler, a suction apparatus, comprising in the preferred form thereof a suction-box located beneath the wrapper-conveying run of the belt and cooperatingwith this run, which has transverse openin gs or perforations therethrough, being illustrated herein for holding the strip firmly onto the belt. As I have found in practice that the inner edge of a continuous wrapper-strip is liable to slip out over the outer edge of the strip in winding the latter around the tobacco rod unless'the inner edge is held firmly in place, I deem it an important feature of my improved machine to provide a presser device, located between the former-rolls and the belt by which the wrapper is fed, for holding and pressing such inner edge of the. strip firmly in position as the pasted outer edge of the strip comes into position for breaking joint therewith, and I prefer to employ for this purpose a vibratory presser-roll having a rapid movement for pressing or tucking in the inner edge of the continuous wrapper and a flared end so shaped as to aid in giving to the finished continuous cigarette its cylindrical conformation.

Another feature of my present invention relates to winding means whereby after the finished cigarette-body passes beyond the former-rolls its movements both in rotative and longitudinal direction will be slightly accelerated, so as to cause a slight stretching of the finished cigarette and to give thereto an additional twist for setting the paste on the. outer edge of the wrapper and at the same time giving this outer pasted edge a slightlyfirmer hold upon the inner edge of the wrapper that is W und around the filler-rod in substantially the same manner that a finished cigarette is stretched and wrapped or twisted by hand.

Another feature of my invention is the provision of a swinging former device shiftable from a working position to a non-working position in which the operation of shaping the tobacco rod and applying thereto the wrapper may be observed by the attendant at any stage in the formation of the continuous cigarette; and still another feature is an improved paste-applying device disposed below the plane of the wrapper-belt, out of the way of the operator, having means for adjusting the position of the discharge-nozzle thereof with respect to the outer edge of the wrapperstrip and also for positively controlling the feed of the paste to said wrapper.

Similar characters desi nate like parts in all the figures of the drawings.

The several operative parts of my machine may be carried by any suitable framework, that shown herein comprising a hollow col umn 2, rising from a suitable base, (not shown,) on which column is supported a table 4, by which the principal operative mechanisms are carried.

The machine illustrated in the drawings of my present application embodies a plurality of coordinate devices or m echanisms,the main portions of the machine being filler-feeding means, such as F a pair of conveyers or endless belts, such as A A; wrapper -feeding IIO means, such as B; paste applying means, such as O; filler-forming and wrapper-applying means, such as D; cutter mechanism such as E, and winding mechanism, such as G, for finishing a continuous cigarette.

The table 4 forms in the present instance a carrier for supporting the upper runs of the belts A A, which constitute, respectively, filler-conveying and wrapper-conveying belts. The filler-belt is carried at one end on a bandwheel 6, secured to the main shaft '7 of the machine, and at its other en d on aband-wheel 6, supported on an adjustable yoke 8, carried at the under side of the receiving end of the machine. The Wrapper-conveying belt A may be supported-at its delivery end on a band-wheel 00, carried by a'short shaft (see Fig. 12) beyond the main shaft 7 and parallel therewith, while the receiving end of said belt may be carried by a band-wheel 60" beneath the table 4 in a manner substantially similar to that in which the receiving end of the filler-conveying belt is supported. It will be noticed that the two endless conveyers are disposed side by side with their carrying-runsin substantially the same plane and their inner edges in juxtaposition, the surface of the filler-carrying belt being slightly above that of the wrapper-belt, so that the filler when formed into a continuous tobacco rod may pass off onto the wrapper fed by the wrapperbelt without being interfered with by the inner edge of said belt A.

The wrapper-feedin g means employed in this instance comprises a wrapper-carrying reel, which may be carried for rotation in-a swinging frame or arm in such a manner that its weight will hold the wrapper-strip firmly against the wrapper-belt at the point where the wrapper leaves the reel. This wrapperreel is shown at 16 and is preferably supported loosely on a cylindrical carrier 1 5', projecting laterally from the free end of an arm 14, supported for swinging movement by a bearing 14 on the table 4. This wrapper-reel, however, does not form the sole means for controlling the advancing movement of the wrapper-strip, but in connection with this reel I also make use of a suction apparatus for holding the wrapper-strip firmly onto the belt from the point where it leaves the reel to that at which it is wound around the filler. This suction apparatus is organized to cooperate with the upper run of the wrapper-conveyin g belt in such a manner as to constantly draw the wrapper-stri p against the face of said run, and hence it will be obvious "that this belt should have openings therethrough to permit the suction or exhaust apparatus to act upon the wrapper-strip. These openings are represented herein perforations p, and are preferably arranged in parallel circuits around the wrapper-belt, the rows of perfo-.

rations being close together for the purpose of permitting the suction or exhaust apparatus to act upon the wrapper-strip at a multiplicity of adjacent points.

The suction apparatus may be of any suitable construction and preferably comprises a suction-box (designated in a general way by s) communicating with a suitable exhaust fan or pump, (indicated by dotted lines at s, Fig. 8,) an exhaust-pipe of ordinary constructionbeing shown as the connecting medium. This suction-box is in this instance formed as a chambered portion of the table 4 of the machine and preferably has a lid or plate set into the face of the table and formed with a series of openings adapted to communicate with the perforations in the belt A. Moreover, these openings are preferably formed as parallel slots 101, having the same intervals between them as between corresponding runs of perforations in the wrapper-belt, and in addition to this said belt is located in lateral direction by guides which may be formed by properly channeling the face of the table 4, as shown in Figs. 7 and 8, so that the belt will have its upper facesubstantially flush with the surface of the table 4. The slots 101 do not in this case extend entirely through the plate 100, but connect at intervals with openings formed by transverse bores 102 passing through the inner side of the plate 100.

For the purpose-of feeding loose filler material to the filler-conveying belt and partially shaping the same to form a tobacco rod I prefer to employ the filler-feeding device illustrated at F. This may embody an inclined feed-board or feed-table 103, fixed on the main table 4 and preferably between a pair of

uprights

104 and 104, in which is journaled a driving-shaft 105 for actuating a pair of coacting rolls cooperative with the feed-table. This shaft carries in the present instance a band-wheel 105, which may be driven by a belt from any suitable source of power, and said shaft also has fixed thereon for rotation therewith a pair of cam-

wheels

106 and 106 and a driving-pinion 107. This pinion may mesh with the teeth of a gearwheel 108, carried loosely on a rock-shaft 109, supported in an upright 104, which gearwheel 108 serves as an idler for driving the gear-Wheel 110, fixed on the outer end of one of therolls just described and driving in turn a similar gear-wheel 110 onthe end of the other of said rolls. These rolls will in the present construction be mounted in the manner shown in Fig. 5 in the ends of rockarms 112, secured to the rock-

shafts

109 and 109, it being understood that these parts are duplicated at the inner end of the fillerrfeeding device.

Antifriction-rolls are represented at 113 on the upper ends of rock-arms 113, rising from the rock-shafts 109 and 109', these parts being also duplicated at the inner end of the filler device. The cam-

wheels

106 and 106 cooperate with these antifriction-rolls to actuate the rock-arms and therebythe gears 110 and 110 toward and from each other, these causing the rolls which are shown at 115 and 115, Fig. 6, to move in the same loose filler material as it is fed between said rolls and the latter are oscillated back and forth. The cam-wheels and the friction-rolls are only operative for actuating the feed-rolls in one directionviz., toward each other while suitable springs 116 at opposite ends of the filler-feeding device may be employed for normally holding the rolls away from each other. It will be obvious, of course, that in order to enable the

gearwheels

110 and 110 to mesh without binding while they are oscillated back and forth by the action of the cam -wheels and springs the teeth of said gear-wheels should be considerably longer than those ordinarily used.

The rotation of the feed-rolls by their pinions serves to partially shape the filler material to a cylindrical form as itis fed between and beneath the rolls, so that when the fillerrod is delivered from between the inner ends of these rolls its cross-section will be substantially as shown in Fig. 6that is to say, it will be approximately cylindrical and will be shaped into a perfect cylinder by the action of the former-rolls of the former device, which. will now be described.

As the wrapper is fed off from the wrapperroll the free end of the strip passes through the filler forming and wrapper applying means D, which constitutes a former device for shaping the tobacco rod into a cylindrical body as it emerges from the

rolls

115 and 115, and also serves to apply the strip to the fillerrod for forming a continuous cigarette. The filler-forming device is preferably a unitary structure removable bodily from and similarly insertible into its working position, and comprises a carrier supporting a plurality of former-rolls divergent from a determined point in one direction and parallel from such point in the opposite direction, one of said formerrolls extending obliquely across both the filler-conveying and wrapper-conveying belts, while the second former-roll 34 extends across the wrapper-belt only and parallel with the roll 33, the third roll 43 being rotatively connected with the roll 34 at the inner end thereof and passing across the filler-conveying belt obliquely to the roll 33. The carrier represented herein comprises a pair of end pieces in which the outer ends of the former-roll are journaled for rotation, these end pieces (designated, respectively,by 27 and 27) being preferably bolted to the table 4 and the rolls being supported thereby in such a manner that the filler-forming device as a whole may be removed from the table by withdrawing such bolts.

The rolls 34; and 43 maybe rotatively connected in any suitable manner. In Fig. 1 the roll 43 is mounted for rotation on a spindle 35 and has a bevel-gear 36 carried at the end of a sleeve seated in the bore or journal of said former-roll, said sleeve forming a bushing around the spindle and the spindle having on the end thereof a spherical bearing 35, seated in a corresponding socketin the bevelgear The roll 3% has a similar bevel-gear 40 secured in the end thereof and within a cap 39, secured to the end of said former-roll and projecting therefrom, the end of this bevel-gear also having a socket for receiving the spherical bearing 35. This organization of devices forms both a universal connection and a driving connection between said rolls, as will be evident when the parts are properly held in position, and this is accomplished by means of a cap 39, which is engaged between the bevel-gear 36 and the flared end 38 of the roll a3, surrounding such gear.

In order to permit the attendant to inspect the operation as the filler-rod is formed and the wrapper-strip is wound therearound, I prefer to so construct the filler-forming device that the rolls 3i and 43 may be swung up and away from the endless conveyers and the product observed as the material thereof passes through the machine. Hence I have provided at 28 and 30 a pair of swinging arms, preferably loosely mounted on the spindle 32 of the former-roll 33, between the respective ends of said roll and the

end pieces

27 and 27, and the outer ends of the rolls 3i and 43, respectively, are supported in the free ends of said

arms

28 and 30, so as to rotate freely therebetween.

Any suitable means may be employed for holding the filler-forming device in its normal position, latches 120 and 120 being illustrated for this purpose, these latches being secured to any suitable fixed portions of the apparatus.

In order that the material may be fed forward and the filler-rod shaped between the former-rolls in the best possible manner, I have found that it is desirable to provide obliquely-disposed rolls with faces so roughened that the filler material will advance along the same and on its conveying-belt, but will be held between the same and kept from slipping out in lateral direction. Hence the former-rolls shown in this case have their peripheral surfaces longitudinally grooved or flanged, so that they will grasp the tobacco, and this, in connection with the oblique disposition of such rolls with respect to the filler-conveying belt, will cause the tobacco to be advanced positively by the rotation of such rolls and the forward movement of the belt.

As herein stated, the delivery end of the filler-conveying belt is considerably in the rear of that of the wrapper-conveying belt, and I make use of this organization of the conveyers to locate between the belts at the delivery end of the filler-belt a Wrapper-guide and a filler-sha per disposed obliquely to the conveyers and substantially in alinement with and between the former-rolls, the receiving end of this guide being substantially ICC) at the point where the tiller passes off from the filler-belt onto the wrapper on the wrapperbelt and the wrapper is applied to the filler.

Preferably the guide and the filler-shaper are combined in a single device, which is represented at 122 and is secured to one edge of the table 4; and has its receiving edge in contact with the carrying-faces of the two belts, While the filler-shaper is formed by the grooved wall extending from the receiving edge 122, Figs. 7, 10, and 11, to the formerroll 33, said grooved wall being designated by 122". It will be noticed by reference to Figs. 7, 10, and 11 that the under side of this device is so shaped as to accommodate itself to the positions of the belts and that the outlines of the guide and the sharper vary from the point to the heel of the device, this being substantially plow-shaped and having its receiving edge somewhat convex, so as to throw the inner edge of the wrapper-strip away from the face of the belt and prevent its catching on the point of the guide, while the filler-shaper, which at its receiving end has its wall defined by a curve only approximating the true curve of the finished cigarette, has a curved wall at. its delivery end which is an exact circle defining the periphery of the finished cigarette, and hence serves to shape the latter to a proper cylindrical form before the continuous cigarette passes beyond the shaping device.

In applying the wrapper-strip to a continuous' filler-rod the wrapper is usually presented to the filler-rod at a very acute angle with respect to the longitudinal axis of the filler-rod, and as the strip is comparatively narrow the inner edge thereof is very liable .to slip out from the outer edge of the wrapper as this is wound around the filler-rod unless the inner edge is positively positioned during the wrapping operation. 4

For the purpose of maintaining the inner edge of the strip in its proper position I prefer to employ, in connection with the formerrolls and the belt on which the wrapper travels, a presser device between these rolls and the belt which will press the inner edge of such wrapper firmly against the filler-rod during the winding operation. This presser device (designated in a general way by r) is preferably in the nature of a presser-roll 125, mounted'between the former-rolls and the belt so as to be capable of movement toward and from the roll 33, this presser-roll having a flared end 125, so shaped as to hold the inner edge of the wrapper-strip positively in position and at the same time aid in giving a cylindrical contour to the continuous cigarette. This presser-roll may be loosely mounted on one end of a rock-arm 126, secured to a rock-shaft 127, journaled in a projection 27, rising from the carrier 27, said rock-shaft also having secured thereto a second roclcarm 128, carrying an antifrictionroll 129, adapted to be actuated by a camwhcel 130, having a plurality of cam-faces,

which camwheel is secured to a spindle 131, carryinga spur-gear132 in mesh with the pinion 33 on the former-roll 33. Asuitable spring, such as 133, may be employed for operating the rock-arms, and hence the presserroll, in one direction-via, away from the inner edge of the .wrapper-stripwhile the cam-wheel will serve to positively actuate said presser-roll toward said edge of the wrapper, it being understood that this presserroll will have a rapid vibratory movement, so that it will be substantially constantly in engagement with the edge of the wrapperstrip, the roll 125 of course turning as the continuous cigarette advances, and hence offering no obstruction to the feed of the same.

In order that the presser-roll may be brought into position for operating upon the cigarette, it is desirable to reduce one of the formerrolls-as, for example, the roll 34as shown at 34", to form a space or opening between the rolls, through which the rock-arm carrying the presser-roll may be passed and in which it and said presser-roll may be vibrated.

It will be obvious, of course, that the portion 34: of the roll 34 should be reduced sufficientl y to enable the rock-arm 126 to vibrate freely in the space between the former-rolls without striking or interfering with theoperation of either of said rolls.

In connection with the mechanisms and instrumentalities hereinbefore particularly described any suitable paste apparatus may be employed for applying an adhesive, which will herein be referred to as paste, to the inner edge of the Wrapper-strip, that herein.

represented consisting of two main parts viz., a main paste-reservoir and a paste-feeding mechanism yieldingly connected therewith and detachable therefrom. This yielding action permits adjustment of the pastefeeding mechanism, so as to bring the supplynozzle to any desired position relatively to the outer edge of the wrapper without moving the paste-reservoir, and by making the parts detachable from each other the reservoir may be removed and refilled without changing the position of the paste-feeding mechanism. The main paste reservoir is preferably secured to the frame by a key-and-slotconnection, as shown in Fig. 20, so that it may be removed readily from the machine for replenishing the supply of paste therein, and this reservoir or can, which is designated by 52, has suit-able means for maintaining an uninterrupted flow of paste from the reservoir to the discharge-nozzle of the paste-feeding device. In the present instance the reservoir 52 carries a plunger 59, attached to a stem 60, carried in the end of an arm 61, secured to a rack-bar 62, mounted for reciprocation in a hollow stem '53, which may be formed integra-l with the reservoir 52. The teeth of this rack-bar mesh with the teeth of a spur-gear 63, supported on a spindle 64 within a gearcase 54, a coil-spring being shown at 65 fastened at one end to said gear-case and at its other end to said gcar-wheel for the purpose of forcing the plunger 59 gradually inward as the supply of paste or glue in the reservoir is reduced. A hand-lever 66 is preferably carried on the end of the spindle 64 for winding up the spring.

A suitable pipe 152, preferably flexible, may connect the reservoir 52 with the paste-feeding mechanism shown herein. This pastefeeding device comprises as its essential features a casing 67, closed at one end by a cap 67', these two parts being bored in alinement with each other to receive the journals of a gear-wheel 70, which gear-wheel in turn has its hub longitudinally bored to receive a spindle 71, which constitutes a rotary feeder for positively supplying paste to the dischargenozzle of the paste apparatus. At one end of this spindle a feed-pinion 69 is fixed, and this in turn drives a second pinion 69, rotatively mounted in the face of the casing 67.

For the purpose of connecting the feedspindle 71 with the gear-wheel 70 a couplingsleeve, such as 71, may be splined on the spindle in the manner shown in Fig. 20, so that it may be reciprocated freely, but will be held against rotation relatively thereto, a projecting lip, such as 71", being represented for the purpose of engaging the walls of a corresponding recess 71' in the end of the hub of the gear 70, it being understood, of course, that this gear -wheel constitutes a driver for the feed-spindle and feed-pinions.

Another cap or plate is shown at 7 2 for covering the opening 180 and the gears (59 and t9 and forming a pocket into which paste may be fed through the pipe 152 to said opening, and from which pocket the paste may pass in any suitable manner, as through a short delivery-pipe '73, to a discharge-nozzle 73. This cap 72 may be secured in position by screws and is preferably formed with a channel 72, communicating with a passage 72" through a boss 2", into which the delivcry-pipe 73 is inserted. It will be noticed by reference to Figs. 27 to 29, inclusive, that the discharge-nozzle of this delivery-pipe is substantially rectangular and has three of its edges in a common plane, so that they will lie fiat against the wrapper-strip,and the paste will be delivered from one side of the dis charge-nozzle. Moreover, the position of this discharge-nozzle with respect to the edge of the wrapper may be exactly determined, the adjustment of the same being effected in this case by means of an adjusting-screw, such as 74, working freely in a bore 74 in the casing 67 and having its lower end in position to be received in a correspondingly-threaded bore in a fixed portion of the framework. It will be noticed also that the discharge-nozzle of the paste apparatus is located substantially at the point where the edges of the wrapper meet in folding, so that the paste will be applied to the outer edge of the wrapper just before the latter is folded over onto the inner edge of the strip.

As has been hereinbefore stated, the fillerconveying and wrapper-conveying belts are carried on different driving-shafts, the former being driven by the main shaft 7 and the latter by the shaft 70', so that the belts may be enabled to travel independently of each other. I employ this organization for the purpose of advancing one of the belts at a different rate of speed from that at which the other travels and especially for actuatin g the carrying-run of the wrapper-conveying belt at a slower rate of speed than that of the filler-conveying belt, the object being to feed the filler-rod forward somewhat faster than the wrapper-stri p, and thus while winding the wrapper tightly around the filler-rod also causing the latter to be compressed tightly by the pull of the wrapper-strip as it passes around said filler-rod. I prefer to operate the belts A and A in such a manner that whether or not each one runs at a constant rate of speed the difference between the movements of the carrying-runs of the two conveyers will be the same at all times, and hence in the drawings I have illustrated a gear-train for forming a positive driving connection between the shafts 7 and 70, (see Figs. 12, 13, and 14,) this gearing being in the nature of a reducing gear-train, by means of which the shaft 70 is caused to revolve somewhat more slowly than the main shaft '7. This train of gearing in the present-instance comprises a gear 135, secured to one end of the shaft 7 at the end opposite the main driving-wheel, (designated by D,) and an idler (shown at 136) supported on a carrying-pin 137 and meshing with the teeth of.

a gear 138, secured to the short shaft 70, the

gears

136 and 138 having each two teeth more than that represented at 135.

The former-rolls hereinbefore particularly described are also preferably driven from the shaft 70, a second gear being represented at 139 on such shaft in mesh with a pinion 140 on the spindle 141, this spindle having fixed thereon worm-

gears

142 and 143, meshing, respectively, with corresponding wormgears 33 and 34 on the extended delivery ends of the former-

rolls

33 and 34, it being understood that the former-rolls will be rotated in the same direction at a relatively rapid rate of speed with respect to the rotation of the shaft 7 0'. The former-roll 33 also carries, as before stated, a pinion 33", which meshes with the teeth of the wheel 132 on the spindle 131, from which power is transmitted to the winding and cutting mechanisms G- and E. This spindle is supported for rotation in a journal in the upper end of an up right 144, (see Figs. 14 and 15,) and this upright also has a long bearing 144', in which is journaled for rotation a spindle 145, carrying at one end thereof a pinion 146 in mesh with the gear 132 and having secured to its other end a spur-gear 147 of large diameter having a long hub 1.47, on which are fixed a large worm-gear 14S and a spur-gear 149 of somewhat larger diameter than the gear 147.

Between the upright 144 and the delivery end of the machine is another standard 151), shaped to form an annular support or ring 150, in which is mounted for rotation the hub 15l'- of another large gear 151 in mesh with the teeth of the spur-gear 149. v

The gear 151 is held in place in the annulus 150 by a spur-gear 152 and a circular rotary carrier 153, said carrier being secured to the hub 151 of the spur-gear 151 in any suitable manneras, for instance, by means of the bolts 154. The spur-gear152 is not fastened, however, to the rotary carrier 153, but is in the form of an annulus having a circular flange or rim 152, on which rests a corresponding circular flange or rim 153 of the rotary carrier, the construction being such that while all of the parts are held securely against axial movement the gear 151 and the carrier 153 will be free to turn together in the annular support 150, while the annular spurgear 152 will turn freely on the carrier 153. This gear 152 also has secured thereto or integral therewith an annular spiral crown-gear 155, and as the teeth of the spur-gear 152 mesh with the teeth of the spur-gear 147 it will be obvious that said gear 152 will rotate somewhat more slowly than the gear 151 and the rotary carrier 153.

The gears supported by the annulus 150 are so positioned that their common axes are substantially in alinement with the continuous cigarette as the latter emerges from between the former-rolls; and, for the purpose of permitting said continuous cigarette to pass beyond, and be operated upon by, the winding mechanism, of which these gears form a part, the rotary carrier 153 and the spur-gear 151 are axially bored, as shown at 156, the diameter of the bore being somewhat larger than that of the cigarette. The carrier 153 is also preferably form ed with a plurality of journalbearingsin the present instance three in numberhavingtheirlongitudinal axes equidistant from one another and intersecting the axis of the gear 151 and the carrier 153. Moreover, these journals are so positioned as to support spindles 157, carrying feed-rolls 158, in such a manner that the faces of the feed-rolls form a substantially complete circle somewhat smaller than that defining the periphery of the cigarette. (See Fig. 15.) These feed-rolls are driven in the present instance by pinions 159, secured to the ends of the spindles 157 opposite to the feed-rolls, the pinions being so disposed that their teeth mesh with the teeth of the spiral crown-gear. It should be understood that all of these parts are so organized relatively to one another that the feed-rolls will receive the finished continuous cigarette, and, firmly engaging the same, will tend to carry the cigarette along with a slightly-accelerated advancing movement; also, that the rotation of the rotary carrier is at such a rate as will cause the feedrolls to be revolved orbitally at a speed sufficient to accelerate slightly the rotation of the cigarette which they surround. The combined movements of these feed-rolls are effective, therefore, to slightly stretch the contin uous cigarette during the last stages of the process of manufacture and at the same time to give a slight additional twist to the wrapper to tighten the hold of the outer edge of the wrapper-strip upon the inner edge of such wrapper and thus cause the paste applied to the outer edge to set and adhere firmly to the body of the wrapper-strip, the appearance and quality of the cigarette being very much improved by the action of this winding or finishing mechanism.

The cutter mechanism E for cutting or separating the cigarette from the continuous rod is operated from the pair of

shafts

160 and 161, the former being supported in

bearings

162 and 163, (see Fig. 14,) risingfrom the table 4, while the latter is disposed in parallelism with the shaft 160, and considerably above the same, and is supported by corresponding

bearings

164 and 165, (see Figs. 18 and 19,) also integral with the framework.

To the shaft 160 is secured a pair of gears, one of which, a spiral gear 166, is in mesh with the large spiral gear 148 and is driven thereby, while the other gear 167 is in the nature of a spur-gear for transmitting the m ovements of the shaft 160 to the shaft 161 for imparting certain movements to the cutter devices. The shaft 160 has also secured thereto a cam 168, in the nature ofa wiper, for oscillating the cutting'knife in the direction of and in unison with the advance of the continuous cigarette as it passes beyond the winding mechanism hereinbefore described.

The knife itself, which is designated by 81, will preferably be removably carried on the free end of a swinging arm 169, pivotally supported on the upper end of a rock-arm 170, (see Figs. 18, 19. and 31,) secured to the shaft 161 for oscillation therewith.

The oscillation of the knife-carrier or knifeframe in the direction of movement of the cigarette is effected, as before stated, by the wiper 168, a rock-arm 172, fixedly secured to the shaft 161 and carrying at its outer end an antifriction-roll 172 in contact with the-cam 168, being employed for this purpose. A spring, such as 173, preferably connects the rock-arm 172 with the table 4 for returning the knife-frame to its normal position after the roll 172 has been raised to the top of the cam 168.

IIO

The knife 81 is intended to sever the cigarettes by substantially vertical movements of the swinging arm 169, this being constructed to oscillate in a vertical plane, it being preferably raised to an extreme upper position by a quick let-off cam-wheel and drawn down with a rapid movement by a strong spring.

This swinging arm may be provided with a projecting vertical arm 171-, having a thin edge for a purpose hereinafter to be speciiied. The arm 169 is m ountcd in this instance on a stud 17 preferably screw-threaded into the free end of the rock-arm 170, one end of a torsion-spring 175 being secured to the arm 169, while the other end of said spring is fastened to the stud (see Fig. 18) for the purpose of vertically actuating the knife carrying arm.

On the shaft 161 is supported loosely for retation a sleeve 171, having fixed thereon or integral therewith a gear-wheel 176 in mesh with the gear 167, and said sleeve also carries a cam-wheel177, cooperative with the arm 174:, for actuating the knife vertically. It will be noticed that this cam has a substantially circular periphery, except at one point, where it is cut away to form a cam-face 177, (see Fig. 31,) having a straight radial drop sufficient to permit the knife to pass entirely through the continuous cigarette and sever the same,

' a second cam-face 177" connecting the camface 177 with the circular periphery of the cam-wheel.

Between the sleeve 171 and the bearing 165 a second sleeve 178, preferably externally screw-threaded at its outer end and flanged at its inner end, is represented, while on this sleeve and between the flange 178 and a threaded washer or nut 178 an annulus 17 9, preferably a wooden ring, is mounted, so as to turn loosely on the sleeve 178 and support the cigarette at the point where the cutter severs the same from the continuous rod, this point being, as will be obvious, substantially in a radius drawn from the axis of the shaft 161 and in which radial line the cutting-knife operates.

As successive cigarettes are cut from the continuous body by the chopping action of the knife the annulus or cutter-block 179 will turn freely in the plane of the cigarette-body, successive portions of the periphery of said block being presented to the knife as the block is turned by the advancing continuous cigarette.

The operation of a machine constructed in accordance with my present improvements as herein set forth is as follows: It being understood that the main driving-wheel D will be rotated continuously from some suitable source of power in the direction indicated by the arrow in Fig. 1 and that the band-wheel 105' will be rotated independently it will be seen that the filler-conveying belt will start traveling, that the wrapper-conveying belt will be actuated in the same direction at a somewhat slower rate of speed, that the former-rolls will be driven from the drivingshaft '70 through the gear-train shown in Figs. 12 and 13, and that the winding and finishing mechanism will be actuated from the formerroll 33 through the gear-train illustrated in Fig. 14, while the cutter mechanism will in turn be controlled in its movements by such winding mechanism, and the driving-gear will be actuated by the gear-wheel 138, Fig. 1 3, for feeding the past 0 to the wrapper-strip. It being understood that loose tobacco will be fed onto the feed-board F in any suitable manner, it will be seen that the tiller material will. be partially shaped into a filler-rod (see Fig. 6) between the

rolls

115 and 115 by the conjoint action of the traveling fillerbelt and the rotary vibratory rolls, the partially-formed fillerrod being delivered then by the filler-eonveyingbelt to the former-rolls, between which it is shaped to a substantially cylindrical form, it being carried then otf from the filler-belt and onto the receiving edge of the combined wrapper-guide and fillershaper 12" Here the wrapper-strip, which has just been paid out from the wrapper-roll and is held closely against the carrying-run of the belt by the action of the suction or exhaust apparatus, (represented in Figs. 7 and 8,) passes onto the receiving edge of the wrapper-guide and is wound around the filler-rod, between the latter and the curved wall of the filler-shaper, the slower advance of the Wrapper-strip serving to wind the same tightly around the filler-rod. As the wrapper is wound the filler-rod passes beyond the fillershaper, the presscr device engages the inner edge of the wrapper-strip, and, vibrating rapidly, acts to tuck in such edge and hold the same firmly in place as the outer edge of the strip is wound spirally over that portion of the wrapper which is adjacent to the inner edge thereof. The rapid vibration of the presscrroll also acts to partially shape the filler-rod while keeping the inner edge of the wrapperstrip in place.

The discharge-nozzle of the paste apparatus is located directly beyond the presscr-roll, as will be clear by reference to Fig. 1, so that the paste is applied to the outer edge of the wrapper-strip immediately beyond the point at which the outer edge of the wrapper is e11- gaged by said roll, and just before the continuous cigarette emerges from the formerrolls the latter press the opposite edge of the strip firmly upon the previously-wound portion of the wrapper. The endless cigarettebody now passes between the feed-rolls 158 of the winding mechanism, and its rotation and advance are slightly accelerated, thus drawing the continuous cigarette toward the delivery end of the machine and stretching the same longitudinally, while giving an additional twist to the same in circumferential direction for setting the paste and giving a finished appearance to the completed cigarette.

As the cigarette-body passes beyond the opening 156 in the winding mechanism it is received on the upper face of the circular block 179 and at the proper moment-that is, when the arm 174 reaches the top of the camface 177 it is forced off from the same by the spring 175, and a rapid cutting movement is imparted to the knife 81, such as will carry the cutting edge thereof through the endless means for rotating said rolls; and means for cigarette with a sharp blow and sever and separate a cigarette of proper length from the endless cigarette-body, the knife advancing, of course, in unison with the continuous cigarette during the cutting operation and until it is clear of the cigarette, when said knife is returned to its normal position by the wiper 16S, acting upon the rocker 172.

By means of the combined devices and mechanisms hereinbefore described I am enabled to form cigarettes with great precision and withoutinjuringthewrapper,the finished cigarette-body, or the separate cigarettes at any stage in the process of manufacture.
