  • the holders in addition to their function as a iiller-carrier the holders ' also serve to more completely form the filler while they grasp and carry it. This additional function has been found desirable in that the filler does not remain in the delivery-tube j"7 a sufiicient length of time to partake of the circular shape.
  • the movements necessary to cause the holders Z9toclose around the ller and at the required time open to release the same are imparted by a cam-slotZ19, contained by a plate ixedly mounted on the side of the bar l.
  • This cam-slot is engaged by a stud Z19, projecting from the end of a lever Z, that is pivotally mounted to the lower end of the frame L and atits opposite end is connected with the arm Z5 of one of the holders.

  • the severingdevice O (best shown in Fig. 26) is mounted on the table, and consists of a fixed jaw o', carrying a cutting-edge o2 and a movable jaw 03, pivoted to the fixed jaw and carrying a cutting-edge 04. mounted to give a shearing cut to the strip to sever it transversely into wrapper lengths.
  • the requisite movement is imparted to the movable jaw o3 against the pressure of a spring 05 from a cam h7 on the main shaft, and a connecting-rod o, having a bowl 07 operated upon by said cam.
  • the action of the feed-roll M2 is to intermittingly feed or pay off from the web a definite length of the wrapper-strip, which, snpposing the strip to be taut, as seen in Fig. 22, before this action of the feed-roll, will provide a quantity of the strip hanging loose between said feed-roll and the guide-bar as, no forward movement of the strip having takenplace in the guide N.
  • the plate 'a5 will also be light enough in weight to be lifted by the paper strip when it is drawn taut in the operation of feeding or carrying it forward through the severing device, and at the instant the strip is severed the forward portion thereof, not being under tension, will be readily withdrawn by lthe weight of the plate as it tends to seat itself in the recess n10.

The opposite sides at its lower face are cut away, as in Fig. 25, to permit the line of paste that may have been applied to either one of the edges of the strip to pass without being wiped off.
  • the wrapper-carrier P operates to seize the end of the strip projecting from the end of said guide N, carry the strip bodily forward until a sufficient length to form a cigarette-wrapper has passed the severing device O, when the carrier will momentarily stopto allow the severing device to sever the strip transversely, whereupon the carrier will again move to carry the severed length into position to thewrapping devices, release said length, and then move to its idle position away from intei-ference with the wrapping means.
  • the wrapper-carrier in the preferred embodiment consists of a reciprocating bar p', adapted to slide by its shoe p9 in ways formed by a guide p10 and moved from a cam hs through a lever p12, pivoted to a bracket-stud d, and connected to the bar by a linkpu.
  • 'lhis reciprocating bar carries at its opposite end a gripper formed by a fixed finger p2 and a movable flnger, rocked open against the force of a spring ps.
  • this tongue is such, it being understood that normally the fingers are closed, that upon the forward reciprocation of the bar on its movement to seize the end of the wrapper-strip, said tongue contacting with a cani or other projection will rock the movable finger open until the two fingers are upon opposite sides of the strip, when a further movement of the bar will release the tongue and permit the fingers to seize the strip between them, when the return movement of the bar will take place.

To all who/wit may concern:
Be it knownthat l, ALBERT L. MUNsoN, a citizen of the United States, residing at New York city, State of New York, have invented certain newand useful Improvements in Cigarette-Machines, fully set forth in the following description and represented in the accompanying drawings.
This invention relates generally `to machines for making cigarettes, and particularly to that class of such machines wherein the tobacco is formed into a proper-shaped iiller and the wrapper is presented in suitable lengths to the filler and wrapped about thelatter to form cigarettes.
The vobject of the present invention is, among other things, to provide an automatic means by which cigarettes having the characteristicsof hand-Work may be readily and economically made; and to this end the invention consists in the -novel structure and cembinations of parts hereinafter fully set forth.
In the accompanying drawings, which illustrate apractical embodiment of the present improvements, Figure 1 is a plan view.

Before entering into a detailed description of the construction and operation of the various instrumentalities which go to make the complete organization illustrated it should be stated that such organization embraces, first, means by which the loose tobacco is formed into a properly-prepared filler of a size suited to the cigarettes to be made, hereinafter called the filler-former; second, means by which the prepared filler is cut off into suitable lengths and fed or carried from the filler-former to the wrapping devices, and hereinafter called the -filler feeder7 or carrier;J third, means by whichan inclosingwrapper is fed forward from a roll, and also lincluding a guide, called the wrapper-feed, fourth, means for applying' a line of cement along an edge of the wrapper, called the pasting device; fifth, means for cutting Said inclosing-Wrapper into cigarette lengths and presenting the same to the wrapping devices, called the severing device and wrappercarrier,7 and, sixth, means by which the filler and Wrapper lengths are brought together and the latter Wrapped around the former, With its overlapping edges united by the line of cement to complete the formation of the cigarettes, and hereinafter called the wrapping devices.7 As herein combined, these devices eo-operate automatically to prepare tobacco in the form of a cigarette-ller, feed said filler intermittingly to the fillersevering device and carrier, which sever or cut oft the desired length of the filler to form a cigarette and then carry the same to the wrapping devices. lVhile these operations are being performed the wrapper, in the form of a continuous strip, is fed or paid off intermittingly from a roll and its forward end is taken by the wrapper-carrier to the wrapping devices about simultaneous with the feeding of the filler thereto, when the Wrapping devices Will operate to envelop the filler by the Wrapper, whose edge or edges, having been properly cemented and overlapped,will be united and a complete cigarette will be discharged froln the machine, and the operations repeated. y v
Referring now to the drawings, it is to be understood that these various instrumentalities are all mounted upon or carried by a supportingtable A, upon which, also, is mounted a driving-shaft H, that imparts the necessary movements to the operative parts of the machine.
The filler-forming devices-dt should here be stated that any suitable devices for preparing and feeding the tobacco in proper quantities to the filler-former may be einployed in connection herewith. The fillerformer G (see Figs. l, 2, and 11 to 17, inclusive) consists of an open trough formed, essentially, of three belts-a horizontally-arranged filler carrying-belt g and two iller-carryingside belts g4 g5, co-operating with the former belt and supported by a lougitudinally-channeled guide F, held from the table by brackets f.
At the forward end of the guide F the trough is continued by a iiller-d elivery guide F, that terminates in a delivery-tube f7, supported from the guide F by a bracket f6. This tube is at one end of rectangular form and gradually merges into circular form of substantially the required diameter of the cigarette-filler. The belt g', forming the bottom of the trough in connection with the delivery-guide F, is stretched around grooved pulleys G G4, the former, at or near the forward or delivery end of the trough, being secured to a shaft g10,that finds bearings in ears f2 on the guide F, and the latter', at or near the entrance end of the filler-former, being mounted in bearings provided by brackets f5. Of the two side belts, Which form the opposite sides of the trough up to the delivery-tube f7, the belt g4 is stretched around grooved pulleys G10 G6 and partially around a third pulley G3. The pulleys G10 are preferably much smaller than the others, so that the side carrying-belts may approach as near the delivery end of the trough as possible, and are each mounted at said delivery end of the trough on vertical studs f, (see Fig. 16,) secured to a horizontal bracket flo, that is supported by the studs fg of the pulleys G2 G3, and by an ear f8, projecting from the upper forward end of the delivery-tube f7, by which construction said delivery-tube is more rigidly supported. The trough is also provided with presser-rolls G11 G12, mounted to turn loosely in brackets eX- tending from the guide. The lower portion of each of these presser-rolls extends into or between the carrying-belts and serves in conjunction With said belts in bringing the filler to proper rod shape as it is fed onward. The pulleys G2 G3 are arranged so that the side carrying-belts approach nearer each other toward 4the delivery end of the trough, thus making the trough slightly taperingin form, and said pulleys are caused to move in unison by supplemental belts g2 and g3, the latter being stretched around the pulleys G3 GG upon the in ner side of the belt g4, and the former stretched around the pulleys G2 G5 upon the inner side of the belt g5, the said pulleys being properly grooved to receive the tWo belts. The belts g2 g3 travel in contact with the sides of the channeled guide F, (see Fig. 15,) which latter is provided with guard-plates f12 to prevent those belts as Well as the carryingbelts from leaving said guide. provided on their under sides with a bevelgear, each of Which meshes with a similar gear carried by the shaft g1", one upon each side of the pulley G. Motion is communicated to the shaft gw, and from thence to each of the belts by a pawl and ratchet, as seen in Fig. 12. Said shaft glo is extended to one side of the trough, where it passes a bearing a', extending from the machine-table, and has fast to it the ratchet-wheel G7, the teeth of which are engaged by the pawl Q9, carried by a pawl-carrier g8, fast to a driven toothed Wheel GS, that is mounted loosely upon said The pulleys G2 G3 are.

Yshaft gm. Thetoothcd wheel,its pawl-carrier,
and pawl are intermittingly rocked from a suitably-shaped cam h4 on the main shaft H, (see Figs. l and 18,) through a rock-arm G9, pivoted at gG to a bracket a2, and having at one end a bowl g7 for contact with said cam, and at its other end a toothed segment g, engaging with the wheel G9. As the cam h4 rotates and the rock-arm thereby vibrated, the toothed wheel G9 and pawl will be correspondingly rocked to impart the necessary intermittent forward movement to the shaft gw, as will be apparent. The degree of movement imparted to the carrying-belts may be conveniently regulated by adjusting a stop 20, Fig. 18, so as to limit the movement of the rock-arm G9 in one direction.
The jZZer-cmv'yng devices-The intermittent motion imparted to the filler-carrying belts of the filler-former is such that at each movement a sufiicient length of the prepared filler is fed through the delivery-tube f7 to form, preferably, asingle cigarette. The devices now to be described, co-operating with said belts of the filler-former and the wrapping devices to be hereinafter described, receive the length of prepared filler, and,after being properly severed from the continuous filler yet under the control of the filler-former, carry or present it to the wrapping devices.
The filler feeder or carrier (see Figs. 3 to 5 and 7) consists,- essentially, of a pair of holders Z9, of semi-tubular form and of a length substantially equal to that of a cigarette, that are secured to the ends of a pair of arms Z4 Z5, pivotally supported from a cross-barLl, forming part of a vertically-movable rectangular frame L. This frame consists of vertical rods L L2, united at their upper ends by a crossbar L3 and at their lower ends by the crossbar L4. The frame is supported and guided in its vertical movements by brackets Z Z2, secured to horizontal bars I l2, forming part of the machine-frame and supported from the table by legs i i2. (See Figs. l and 2.) The vertical rods L L2 of t-he frame carry springs Z3, the tendency of which is to keep the frame in its raised or highest position. )Vhen in this position, the holders Z9 are in alignment with the delivery-tubefZ, (see 2 and 2%) so that the prepared filler may be projected directly between said holders and at the proper time grasped thereby sufficiently to impart by their semi-tubular form a circular shape to the filler-rod, aid in preserving that shape, and to carry it to the wrapping devices. Coacting with the holders is a guard-plate Z7 of about their same length, that is supported directly beneath them by the head of a stud ZS, projecting from the arm Z5, and bya like stud projecting from an arm Z9, pivoted to a bracket Zw, that is secured to the frame L. The connection between said plate ZT and the arm Z5 is a slotted connection permitting a considerable lateral movement between the plate and the arm, Aso that said plate may be moved from the position shown in Figs. 3 and 7 to that shown in Figs. 4 and 5, in which latter position it forms a bottom to the holders when in their separated position, so that the filler projected between them is held in position until the holders are moved together toward it. It will be understood that in addition to their function as a iiller-carrier the holders 'also serve to more completely form the filler while they grasp and carry it. This additional function has been found desirable in that the filler does not remain in the delivery-tube j"7 a sufiicient length of time to partake of the circular shape. The movements necessary to cause the holders Z9toclose around the ller and at the required time open to release the same are imparted by a cam-slotZ19, contained by a plate ixedly mounted on the side of the bar l. This cam-slot is engaged by a stud Z19, projecting from the end of a lever Z, that is pivotally mounted to the lower end of the frame L and atits opposite end is connected with the arm Z5 of one of the holders. The holders are connected to move in unison to and from each other by links Z9, each connected to the opposite ends of a lever Z12, that rocks upon a central stud projecting from the bracket Zw, (see Fig. 7,) and motion is imparted to the guard-plate ZT from the holder or holders by a link Zu, connecting the arms Z5 and Z9, the arrangement being such that the latter arm and the guard-plate are moved faster than the holders, so that the guardplate in one position is beneath them before they move sufficiently to grasp the filler, and in the other position is moved to one side7 as in Fig. 3, to permit the iiller to be deposited in the Wrapping devices When the holders move apart for that purpose. The filler having been projected between the holders and temporarily supported by the guard-plate Z", as in the position of these parts shown in Figs. 4 and 5, the frame L Will be caused to descend through the medium of a cam h5 (see Fig. 3) acting upon the bowl Z9() of a lever Zls, pivoted upon a bracket a5, and connected to said frame by a link Zl9, a spring Z21 keeping the bowl to duty. At the commencement of rthe descent of the frame, carrying with it the holders, the guard-plate, and connecting devices, the cam-slot Z15 being fixed, the latter will cause the lever Z to quickly rock and move the holders together to close upon and grasp the ller, as in Fig. 39. The holders will remain in this position until the frame arrives at or near the limit of its downward movement, when the cam-slot, again acting upon said lever Z, will cause it to rock in the opposite direction, withdrawing the guardplate to one side and opening the holders, so that the iiller is deposited in proper position for the action of the Wrapping devices, as in Fig. 3. The frame-actuating cam h5 will immediately permit the frame to return toits raisedposition, as in Figs. 4, 5, and 6, ready to repeat the operation. This cam h5 is so shaped that the frame is allowed to dwell longest in its raised position, its vertical' ILO ITO
movements being speedy, so that the fillercarrier will not interfere with the proper and timely operation of the wrapping devices. So soon as a proper length of the filler has been projected between the holders Z6, and while they are in alignment with the delivery-tube of the filler-former, Fig. 2, the filler is severed by a pair of cutters le k2, Figs. 19
to 2l. '[hese cutters are located immediately forward of the end of the filler-delivery tube fT (see Fig. 2l) and between the latter and the holders l, (see Fig. 22,) and are pivotally mounted on the frameK, supported by the bars Y' l l2. One of the knives, as 7a2, is guided at its free end by a stud entering a slot 7c3 in the frame. The other is guided and steadied by the said knife k2. They receive motion through links 7a4 from a double bell-crank lever la, that is mounted to a bracket k6, which in turn is rocked at the proper times through the movement of an arm 7.57, also pivoted to said bracket k6 and connected tothe bell-crank lever by a stud 7c8. The movement of the arm k7 is limited in one direction by a stop-piece 7cm, and is vibrated against the force of a spring k. The requisite motion is imparted to the arm la? from a cam on the main shaft, which imparts a reciprocating motion to a carriage C, forming part of the wrapping devices to be hereinafter described.
The wrapper-feeder devices-Phe present machine is capacitated to feed a narrow strip M of material suitable to form an envelope fora cigarette-as, for instance, paper-guide it past a pasting device R, then past a severing device O to cut the strip into wrapper lengths, and through the medium of a carrier P present the wrappers to the wrapping devices. This strip is preferably in the form of a continuous roll or web M', mounted to turn loosely in bearings provided in the brackets depending from the table, as in Figs. 2 and 22. From the roll the strip passes over a feed-roll M2 under a yielding tension-roll M3, partially around a guide-bar as, and then through a longitudinally-arranged guide N. The feed-roll M2 is a plain disk secured to a shaft m3, that is supported in brackets a a7, transversely of the machine and beneath the table A. (See Figs. 30 and 3l.) Intermittent rotary motion is imparted to the feed-roll from a cam h6 on the main shaft through a pawl mand ratchet M4. The ratchet is secured to the shaft m3 and the pawl is carried by a pawlcarrier mi, vibrating loosely on the shaft and having an operating-link m8, adapted to be adjustably connected with the said pawl-carrier to vary its throw. The link carries a bowl m9, bearing against the cam h, and is held to duty by a spring m10. 'lhe ratchet is prevented from turning backward by a stoppawl mi. The tension-roll M3 is hung at the end of a pair of arms m', pivoted at mito the under side of the table. The bar a8 may be a fixed one, or it may turn under the action of the strip. The longitudinal guide N (see Figs. 22 to 25) is supported from the table upon legs ai and a, and is channeled to receive the strip and permit the latter to move through it. The end of the guide N terminates at one side of the severing device O, and at this point is provided with a pair of spring-blades n@ nf), adapted to bear upon opposite sides of the strip, as in Fig. 2t, in such a manner that its severed or forward end is bent somewhat out of the true line of travel. The severingdevice O (best shown in Fig. 26) is mounted on the table, and consists of a fixed jaw o', carrying a cutting-edge o2 and a movable jaw 03, pivoted to the fixed jaw and carrying a cutting-edge 04. mounted to give a shearing cut to the strip to sever it transversely into wrapper lengths. The requisite movement is imparted to the movable jaw o3 against the pressure of a spring 05 from a cam h7 on the main shaft, and a connecting-rod o, having a bowl 07 operated upon by said cam. The action of the feed-roll M2, it will be understood, is to intermittingly feed or pay off from the web a definite length of the wrapper-strip, which, snpposing the strip to be taut, as seen in Fig. 22, before this action of the feed-roll, will provide a quantity of the strip hanging loose between said feed-roll and the guide-bar as, no forward movement of the strip having takenplace in the guide N.
It has been found in practice in using` paper of the quality and Weight'suited to form the envelope for cigarettes that after the paper strip has been severed its forward edge will cling to the surface of the cutter, which renders it difiicult to feed or carry the strip forward. To obviate this imperfect operation and to insure the forward edge of the strip being in proper position to be grasped by the wrapper-carrier, there is provided means by which this edge of the strip after each severing operation is slightly but positively withdrawn from the cutter of the severing'device. Many modes of effecting this movement of the strip may suggest themselves to those skilled in the art, and in the present instance it consists of a plate 77,5, resting upon the surface of the strip and of sufficient weight when the forward 'end of the strip is free to depress the underlying portion into a recess, as n10, in the guide N. This, what may be termed a withdrawing-plate, is shown as pivoted at one end to brackets n4, rising from the guide and having an adjustable stop a7 to limit the extent to which the plate will depress the strip into the recess. (See Fig. 25.) It will be understood that the plate 'a5 will also be light enough in weight to be lifted by the paper strip when it is drawn taut in the operation of feeding or carrying it forward through the severing device, and at the instant the strip is severed the forward portion thereof, not being under tension, will be readily withdrawn by lthe weight of the plate as it tends to seat itself in the recess n10. The accidental disturbance of the strip as it passes through the guide N The jaws areY IOC ITO
may be guarded against and sufficient fric-I tion applied. to the surface of the strip to cause it to move evenly and with the proper degree of tension by any suitable means. One form shown consists of a block n', fitting between the sides of the guide and resting immediately upon the surface of the strip. It is prevented from following the strip as it is drawn or fed forward by a cross-bar n2, lying across its path. (See Figs. 24 and 25.) The opposite sides at its lower face are cut away, as in Fig. 25, to permit the line of paste that may have been applied to either one of the edges of the strip to pass without being wiped off. The wrapper-carrier P, now to be described, operates to seize the end of the strip projecting from the end of said guide N, carry the strip bodily forward until a sufficient length to form a cigarette-wrapper has passed the severing device O, when the carrier will momentarily stopto allow the severing device to sever the strip transversely, whereupon the carrier will again move to carry the severed length into position to thewrapping devices, release said length, and then move to its idle position away from intei-ference with the wrapping means.
The wrapper-carrier in the preferred embodiment consists of a reciprocating bar p', adapted to slide by its shoe p9 in ways formed by a guide p10 and moved from a cam hs through a lever p12, pivoted to a bracket-stud d, and connected to the bar by a linkpu. (See Figs. l, 22, 23, and 27 to 29.) 'lhis reciprocating bar carries at its opposite end a gripper formed by a fixed finger p2 and a movable flnger, rocked open against the force of a spring ps. Upon the same pivot that carries the movable finger there is also pivoted a tongue p5, that is held against a stop p", carried by said finger p3 by a spring p7. The operation of this tongue is such, it being understood that normally the fingers are closed, that upon the forward reciprocation of the bar on its movement to seize the end of the wrapper-strip, said tongue contacting with a cani or other projection will rock the movable finger open until the two fingers are upon opposite sides of the strip, when a further movement of the bar will release the tongue and permit the fingers to seize the strip between them, when the return movement of the bar will take place. In the present instance the reciprocating bar moves over a portion of the wrapping devices, and to permit this a portion of the frame of the latter is cutaway, as at U2 in Fig. 27. At one openingin this frame there is provided a cam-shaped projection 613 in the path of the end of the tongue p5, which, as before described, is struck thereby and rocks it and opens the fingers of the gripper.
The opening of the fingers to release the wrapper length when in position at the wrapping devices may be accomplished in many ways. There is shown a vibrating arm U, Figs. 22, 27, and 29, adapted to press against the tail of the finger p3 and rock it open. At
the time of the action of the armU the barp has come to rest, as in Fig. 22, and immediately after the finger has been rocked open the bar will continue to move to its extreme rearward position, (seen in Fig. 1,) the cam hs being shaped to effect this operation. The vibrating arm U is pivoted to the bar I and is vibrated from a cam 7L on the main shaft, reciprocating a rod u2, connected with the arm and having a bowl uf, bearing against said cam under the pressure of a spring u3.
In moving through the guide N the strip has applied to it, preferably at one edge, a narrow line of paste by the pasting device R. This device consists of a paste-fountain supported above the guide by brackets r, secured to said guide. At the bottom of the fountain a roll r2 is supported-a portion in the fountain and a portion out of it-by a shaft r, that turns in bearings provided in the brackets o", which shaft and roll receive continuous rotary motion from the main shaft by a pair of bevelgears w13, a transverse shaft r1?, and a second pair of like gears rw r, the former of which latter gears is fast to the paste-roll shaft. rlhe opposite surfaces of the roll are borne upon by a pair of spring-plates r3, lying against the bottom of the fountain and regulated in pressure by screws'fri, the action of which is fo prevent the escape of the paste past the roll and fountain bottom. The roll r2 is provided with a radial slot 0', extending its length,in which is seated a paste-applying blade o, the saidv roll and blade extending longitudinally with the strip. The paste-roll rotates just above the upper surface of the wrapper-strip, passing beneath it, as seen in Fig. 32, so that said roll does not meet the strip at any time. The paste-applying blade normally lies with its outer edge flush with the roll-surface, or, as in the preferred construction, slightly below that surface, so that a film of paste upon the edge of the blade will escape the clearing action of the fountain-bottom or of one of the plates r3, and atthe proper time the pastingblade will be moved outward sufficient to apply a line of paste to the edge of the strip directly beneath it. This action of the blade is effected by a cam rh", Figs. 33 and 34, duplicated at both ends of the roll and secured to the sides of the fountain. The blade carries a finger rs, projecting from opposite ends of the roll, which fingers each carry a pin r9, extending through an opening in the rollshaft and contacting with the cam 115, so that in the rotation of the roll the blade will be moved outward. The return. movementv of the blade is effected by'a second cam r, also duplicated on opposite ends of the roll in position to contact with each of the fingers rs after the blade has applied its line of paste t-o the strip. It should be stated that at the time the blade applies its line of paste the IOO strip is stationar v,itsintermittent movement being had after the blade has performed its duty, so that the paste is applied in an unbroken line. As the action of the pastingblade, which in effect is a lateral wiping one, in applying its paste to the strip may tend to disturb the position of the strip in its guide there is provided a temporary holding-finger to obviate such disturbance. A finger r1, Figs. 1,23, and 32,is pivoted at r11 to the side of the guide N, and held pressed upon a portion of the strip in line directly opposed to the contact of the blade with the strip by a spring T18. Just before the movement of the strip the pressure of the finger is relieved by the contact of an adjustable stud r2? of a rod 7119, that is acted upon by a cam 7110, carried by the main shaft. The rod r1 is pivoted to a bracket am, and its bowl 9120 is held to duty upon the cam by a spring '121.
The wrapping cricca-All of the various instrumentalities forming the complete organization have been described with the exception of the devices which act to bring the prepared cigarette-fillers and the wrapper lengths together and envelop the former by the latter and discharge the completed cigarettes. The wrapping devices, Figs. 2 to (i and S to 10, consist, essentially, of a belt or apron D, upon which the cigarette filler and wrapper are deposited, and a traveling blade C11, which imparts a rolling or wrapping action to the apron. The apron rests upon a platen E, and is confined between a pair of side plates B', and the blade C11 is mounted on a reciprocating carriage C, that is guided by blocks c', moving in slotted guideways b in the side plates. The blocks care secured to the carriage by side plates c?. The forward end of the apron is fiXedly attached to the plat-en by a bar b3, conning that end of the apron in a groove in the platen, this end of the platen being inclined to allow the cigarettes to be conveniently discharged7 while the remaining portion islevel. The opposite end of the apron passes beneath a cross-bar b1, and is held by a take-up or let-off rod d, that is mounted in brackets d and provided at one end with a tooth-wheel d2," engaged by a stop-pawl d3. The purpose of thus adjustably securing the end of the apron is to permit the size of the apron-fold d'1, hereinafter described, to be regulated so that cigarettes of different sizes may be properly rolled thereby, to regulate also the tight or loose rolling of the cigarette, and, further, to supply fresh portions ot the apron when 'it becomes worn. The traveling blade c11 lies beneath the apron, and is carried by a bar c3,
adapted to rock in bearings formed by the guide-blocks c of the carriage, and at one end said rock-bar c3 projects to the outer side of the carriage, and is connected by a link c1 to a vertically-reciprocating bar c6, mounted to travel with the carriage and connected thereto by a stud cs, extending through a guide-slot cin the bar, the said stud projecting from a bracket c, rising from the carriage, Figs. 6, 9, and 10. The lower end of the bar c6 has a bowl C10, that engages with the cam-groove ot' a plate-cam B, fixed to one of the side plates l of the wrapping devices. The construction of the parts is such that upon the movement of the carriage C from thc position shown in Figs. 3 and 9 the cam B3 will first permit the traveling blade to move until it brings the fold of the apron over the filler, when said cam will cause it to suddenly rock from its inclined position to the vertical position indicated by dotted lines, Fig. 4, so that the filler is firmly confined in the fold d1 of the apron. The carriage continuing to move, with the blades in this last-named position, will cause the apron t-o roll around the filler and impart a rotary'niotion to the filler preparatory to itsmeeting the wrapper length, which has been properly laid upon the apron by the wrapper-carrier P. Immediately prior to the bite of the apron around the end of the blade reaching the edge of the wrapper length the said cam will cause the blade to rockupward slightly suflicient to loosen the hold of the apron-fold d4 upon the filler, and as the filler arrives over the edge ot' the wrapper lengt-h the cam will again bring the blade to its vertical position, as in Fig. 5,coniining the wrapper` length and filler within the apron-fold d4. rlhe carriage C still continuing its forward movementwill impart the rolling motion to the Wrapper length, (as well as to the tillen) so that the former is brought entirely around the ller with its edges overlapping one another, which by reason of the line of paste applied to the wrapper length will become united, whereupon the said cam will again cause the blade to rock to its inclined position, entirely freeing the now completed cigarette and permitting it to be discharged over the inclined end of the platen just as the carriage reaches the limit of its forward movement. Motion is im parted to the carriage C, and thence to the blade 011, from a cam h2 on the main shaft (see Fig. 3) through a rod 021, having a bowl h3, engaging with the cam, a bell-crank lever C20, and a forked connecting-rod c1, which in turn is connected with the carriage.
To prepare the apron for its rolling action after each cigarette has been formed, so that it lies perfectly flat upon the platen and free from wrinkles or creases, and also to insure the formation of the necessary fold d'1 in the apron behind the traveling blade as the latter begins its forward movement, there is provided a tongue C13, arranged and operated in such manner that immediately upon the discharge of the finished cigarette from the apron it drops with its edge upon the apron, and as the carriage C moves back to its nor- IOO IIO
mal position it follows immediately behind the blade, smoothing the apron down upon the platen in its movement until the blade and the carriage reach their normal position to permit the described operations to be performed as the carriage again moves forward. This tongue 013 is held to a pivoted rod C12, mount-ed to the rear of the carriage C, a spring 015, that is carried by the tongue, (a weight would serve the same purpose,) bearing against a plate c, secured to the carriage, tending to elevate the forward edge of the tongue.
In order to automatically operate the tongue near its forward edge it carries a transverse guide-bar c, adapted in the raised or idle position ot' the tongue to rest and slide upon the surface of each of the side plates B', as in Fig. 8, and in its llower or active position to slide within the guide-slots b. At the limits of the movement of the guide-bar in both directions both of the side plates B are slotted, as bl bs, the former to permit the ends of the guide-bar to pass downward into the guide-slots b', and the latter to permit them to pass up onto the surface of the side plates. In the extreme forward movement of the carriage C and of the tongue one end ofthe guide-bar c1" contacts with a deflector b, pivotally mounted on an upright b5 and held in position by a spring b, the effect of which deilector is to direct the guide-bar into the slot bl, and, by reason ofthe latters inclined position, on the return movement of the carriage and the tongue will direct the tongue down so that its edge bears against the apron, in which position it will travel until the guidebar underlies the slots bs, when the spring will cause it to rise to its idle or normal position.
In order to insure the formation of the apron-fold d4, the parts are constructed to impart an additional or further movement to the tongue cl3. To this end the rectangular frame L, as it reaches the limit of its downward movement in the act of depositing the ller carried by the holders Z upon the apron of the wrapping devices, will contact with the tongue and further depress it, so that its end is carried under the traveling blade c11 sufficient to form the apron-fold di, as seen in Fig. 3. Instead of contacting directly with the tongue, a spring-leaf c1G is interposed, carried by the tongue, so that the tongue may yield slightly and the force of the contact of the frame lessened. So soon as the frame L begins to move to return to its upperposition the tongue will immediately rise to vits idle position, (shown in Fig. 4,) ready for the forward movement of the carriage C.
As the wrappercarrier P deposits the wrapper length in position upon the apron and then moves back to its normal position there is danger of the said wrapper length being displaced by currents of air due to the rapid movements of the parts. To avoid this, there is provided a temporary retainer adapted to rest upon the wrapper length and hold it in position until or just before the filler is brought up to it by the traveling blade cu. This wrapper-retainer (see Figs. 2 to 6) preferably consists of one or more pins s6, two being shown, weighted slightly and supported loosely by a bar si" at the lower end ofl a vertically-movable rod s', which slides in ears s, formed on a bracket S, that is secured to and carried by the rectangular frame L. The rod s carries a spring s3, the tendency of which is to hold it in its raised position with respect to the frame. The rod is also provi-ded with a collar s4, adj ustably secured thereto and engaging the sides of the bracket S to prevent the rod from turning and thus hold the position of the retaining-pinss. Onthe downward movement of the frame L the rod s moves with it until its retainer-pins s6 rest by their own weight upon the wrapper length, when upon a slightly further movement of the frame and rod the collar s4 on the latter will have passed a dog t3, that is mounted at the end of a lever T, pivoted to the bar l. This dog is pivoted to the lever and weightethso that on the downward movement of the rod s its collar vibrates it to one side, and when below it the dog will extend over the collar and prevent it and the rod s from rising, a stop-pin 155 limiting the movement of the dog in one direction. Upon the return movement of the frame L it will carry with it the bracket S, thus compressingthe spring s3 of the rod s', so that at the proper time sufficient power will have been stored up to return the rod and its retainer-pins to their normal or raised position. The latter movement of the rod and its retainer-pins will occur when the dog t3 releases its hold upon the collar s4 of the rod, and to effect this at the proper time a cam or contact plate 018, carried by the carriage C, is made the means by which this is accomplished. This cam is secured to the upper end of the bracket 09, (see Figs. 2,6, 9, and 10,) and in the forward movement of the carriage bears against the' end of the lever T and rocks it against the pressure of the spring t', (which tends to keep its stoppin t2 against the cam-plateZ15,) so as to move the dog t3 from the collar, freeing it, and allowing the rod to return to its normal position. The movement of the carriage C also vibrates the operating-arm k7 of the fillersevering device heretofore described, and shown by Figs. l and 19 to 2l. arm is provided with a pivoted finger 7c, having a stop Z613 borne against a projection k1* of the arm by a spring k12. is rigid with the arm when borne against in onedirection and yielding when borne against in the opposite direction. In the forward movement of the carriage it will contact with the finger k idly; but on the return of the carriage in contacting therewith in the direction of the arrow, Fig. 1), will rock its arm k7 and operate the severing device, as in Fig. 20, which arm after each rocking movement will be returned to its normal position by the force of its spring 769, at the same time opening its cutters, readyto sever the filler that is projected past them into the holders of the filler-carrier.
Motion may be imparted to the main shaft H and through it to the various instrumentalities described in any convenient manner.
There is shown a supplemental shaft H',

Thus the finger mounted in bearings provided ony the table of the machine, and having a pinion IV gearing with a wheel fast to the shaft H. The said supplemental shaft is also provided with fast and loose drivingl belt-pulleys V V and a balance or hand wheel X.
From the foregoing description it is deemed unnecessary to separately describe the operations of the various parts of the improved machine, as those not specifically mentioned will be obvious to those skilled in the art of making cigarettes. It is to be remarked, however, that the operations of the various devices are so timed with respect to each other that they will operate to advance the liller and the Wrapper to the wrapping-apron, the latter being in position to receive said ller and wrapper, and While the wrapping operation is being performed the filler and wrapper for the succeeding cigarette is prepared and ready to be advanced so soon as the wrapping-apron has completed its operation,
- thus rapidly making complete cigarettes in succession, which, from the nature of the apparatus, mode of manipulating the tobacco for the filler, and the manner of inclosing it with the wrapper, will equal hand-made cigarettes.
It is to be remarked in conclusion that the invention is not deemed as limited to the employment of all of the various instrumentalilries in combination in a machine of the character described, as it will be obvious that many of the parts maybe utilized effectively in othercigarette-making machines. So, too, changes and omissions may be made in the machine-as, for instance, the positive paying out of the wrapper-strip from its roll may be entirely omitted, the wrapper-carrier performing the function of drawing` the str-ip from the roll. It has been demonstrated, however, that owing to the frail character ofthe paper necessarily employed this paying out of the strip independent of the feeding action of the wrapper-carrier is moredesirable.
The mode of operating the paste-blade may A be departed from. Instead of using two cams,
as shown, a single box-cam would perform the same function, or one ofthe cams anda spring for returning the blade.
