Claims.

This invention relates generally to cigarettemaking machines, and has particular reference to machines for use in the manufacture of cigarettes of the self-extinguishing type, wherein the wrapper, according to the invention to which my copending patent application Serial No. 664,888, filed April 7,1933, is directed, is provided immediately priorto the tobacco-filling and cigaretterolling operation with a transverse film-like coating of suitable agglutinating substance, to which certain particles of the tobacco adhere dur-- ing the filling operation so as to provide in the finished cigarette an annular, combustion-retarding band of tobacco particles, in union with the inner face of the cigarette wrapper intermediate the ends thereof.

Important objects of-the present invention are to provide a machine for use in making cigarettes of the above general character which is simple in construction, reliable in operation, efficient in use and which is under such automatic control that possible damage to either the machine in its entirety or to any partor parts thereof is positively averted should the traveling web-like wrapper paper break under operating conditions.

Other objects and advantages of the invention will become apparent from the following description, taken in connection with the accornpanying drawings, in which Fig. 1 is a fragmental view, partly in elevation and partly in section, of a cigarette-making machine embodying the invention; Fig. 2 is a. plan view of the machine as viewed from above in Fig.

from the rear in Fig. 1; Fig. 4 is a horizontal, see- Fig. 3 is an elevation of the machine, as viewed tional view taken on line 4-4 of Fig. 1; Fig. 5 is a central, vertical, sectional view of the machine, certain elements being shown in elevation; Fig. 6

an end elevation of the machine, as viewed from the left in Figs. 1 and 5; Fig. 7 is a vertical, sectional view taken on line of Fig. 5 and Fig. 8

a sectional view taken on line 88 of Fig. 1. Inasmuch as the present invention is adapted for use in connection with standard types'of cigarette-making machines, wherein the tobacco filler fed from'a hopper onto a traveling web-like wrapperpaper, which is thereafter folded around the filler and then sealed at its meeting margins, it is deemed unnecessary, for a complete understanding of the present invention, to refer to any details of such standard machines other than the machine frame l0, tobacco hopper I main driving gear l2, printing drum l4, and idler roller I5, about which passes the web-like wrapper paper l8 as it leaves the printing drum to which it is supplied from a suitable source, not shown.

Although the device embodying the present invention may be constructed as a unit capable of being attached to or detached from a standard type of cigarette-making machine, it is herein illustrated as incorporated in such machine as a permanent part thereof by providing the machine frame |0 with an integral frame member I II, on which are supported the various elements about which the present invention centers. Jour nalled in the frame member I1, is a main shaft l8, on the rearwardly projecting end of which is detachably supported a gear assembly 20, by which that shaft is operatively connected-to the driving gear' l2. The gear assembly includes a'gear-carrying arm 2|, which is removably journalled on the rear end of the shaft l8, and is provided with a trunnion 22, on which is carried a gear 24, adapted to mesh with a gear 25, removably secured to the shaft l8 by a gear-retaining nut 26. In order that the gear-assembly 20 may be locked in such position that the gear 24 will properly engage the gear I2 and thereby rotate the shaft |8 in a counter-clockwise direction as viewed in that figure, the arm 2| is provided at its outer end with an arcuate slot 21, adapted for the reception of a screw-threaded stud 28, carried by the frame member l1 and provided with a clamp nut 30, the arc of the slot 21 being struck from the center of the shaft l8 on which the arm 2| is pivotally hung. From the foregoing description of the gear assembly 20, it will be understood that the driving connection which that assembly is adapted to afford be-. tween the gear l2 and the shaft l8 may be severed by releasing the clamp nut and swinging the gear-carrying arm 2| a sufficient dis-. tance in a clockwise direction, as viewed in Fig. 3, to disconnect the gear 24 from the gear I2. Moreover, it will be understood that the gear assembly, including the gear 25, may, if desired for any reason, be. easily removed from the general organization of elements entering into the invention upon removing the clamp nut 30 from the stud 28 and detaching the gear-retaining nut 28 from the shaft l8.

Removably secured to the shaft I8, is a feed roller 3|, of suitable material such as brass, carrying at one end thereof a gear 32, which is also removable from that shaft. Pivotally and removably supported on the shaft I8, is a bell crank lever 34, within one arm of which is removably journalled one end of a shaft 38, the other end of such shaft being removably journalled in a link 31, pivotally supported on the outer end of the shaft l8. To the shaft 36, is connected a gear 38, which is maintained, under all conditions of operation, in driving engagement with the gear 32. Intermediate the gear 38 and the link 31, the shaft 36 is provided with a transfer roller 48, .of suitable material such as rubber, which engages the peripheral surface of theroller 3|, the peripheral speeds of which rollers are identical due to the fact that they are of the same diameter and the ratio of the gears. 32 and 38 which operatively connect them is one-to-one. Carried by the frame member I1, is a trunnion 4|, on which is removably journalled a bearing-sleeve 42, between the reduced portion 44 and the hub portion 45 of which is formed a shoulder 46. This sleeve 42 is provided on its hub portion 45 with a gear 41, which is of the same diameter as the gear 38 with which it is adapted to engage. Removably carried by the cut, as shown in Figs. 1 and 5, and the outer surfaces of which conform in curvature to the peripheral curvature of the transfer roller 48 with which they are adapted to engage, it being noted that the diametrical distance between the faces of the ribs 5| is equal to the diameter of the transfer roller. Carried by the pick-up roller 48, are a pair of oppositely disposed knives 52, which are arranged intermediate the ribs 5| at opposite sides of a plane passing through the axis of the roller 48 and longitudinally bisecting the ribs 5|, it being noted-that the outer or cutting edges of the knives 52 are disposed at a slightly shorter distance from the center of rotation of the roller 48 than are the peripheral surfaces of the rib 5| so that they-will not contact with the peripheral surface of the roller 48 under any conditions of operation.

Carried by the frame member I1, is a yieldable bearing block 54, which is urged by a compression spring 55 toward the pick-up roller 48, the extent of movement of the block toward such roller being limited by an adjustable stop 56, in the form of a lag screw mounted in the frame member I1 andpositioned in the path of movement of the block. Although the bearing block 54 may be movably supported in various ways, it is herein shown as disposed within an opening 51, provided in the frame member, opposite parallel side walls 58 of which are shaped to provide guide ribs 68, which conform to and are received by V-shaped grooves 6|, provided in the parallel side faces of the block. Inv order that the block 54 may be easily introduced into the opening 51 and easily positioned on the guide ribs 68, the

opening, at one end thereof, is sufficiently large to receive the guide block so that it may be moved as to prevent the spring from being unduly dislodged. Carried by the bearing block 54, is a trunnion 64, on which is detachably journalled a contact roller 65. Substantially directly beneath the .contact roller 65, there is disposed a guide roller 66 which is mounted on a stub shaft 61, carried by the frame member |-1.

Suitably located on the frame member I1, is a control device 68, which includes a trip roller 18, disposed intermediate the contact roller 65 and a supporting roller 1| which is associated with the feed hopper H and 'over which the wrapper paper l6 travels asit is drawn along beneath the hopper during the tobacco-filling operation in a substantially taut condition. The trip roller 18 is journalled in the upper or yoke-like end 12 of a vertically' disposed rod 14, which is adapted for'vertical movement within a pair of guides 15, attached to the frame member l1. 'I'helower end of the vertically movable rod 14 is provided with a pin 16, adapted to operate within an elongated slot 11, provided-in one arm 18 of a bell crank lever 88, pivotally connected to the frame member |1,'the other-arm 8| of the bell crank lever being provided with means, such as a weight 82, by which the bell crank lever may be moved in a counter-clockwise direction, as viewed in Fig. 1, under certain conditions of operation, as forexample when the wrapper paper l6 accidentally breaks and consequently fails to maintain the trip roller 18 depressed.

Associated with the control device 68, is an electric switch 84, which includes a stationary contact 85, suitably supported by and insulated from the frame member H, and a movable contact 86,

.carried by and suitably insulated from the arm 8| of the bell crank lever 88. These contacts are maintained open so long as the trip roller 14 is maintained in engagement with the more or less taut wrapper paper l6 as it passes from the contact roller 65 and progressively presents itself in position beneath the hopper II to receive the tobacco filler therefromj If the wrapper paper l6 breaks so that it can no longer maintain the trip roller 18 depressed, the operation of the control device, acting under the influence of the weight 82, is such as to cause the contacts and 86 to engage each other, and thereby close the circuit C of a solenoid 81, suitably supported on the frame member H, the core 88 of which solenoid is pivotally connected to the depending arm 35' of the bell crank lever 34. This bell-crank-lever arm 35' is normally held in its position shown in Fig. 1 by a tension spring 98, one end of which is suitably connected to that arm and the other end of which is suitably anchored to the frame member l1. In order that the bell crank lever 34 may be so adjusted as to effect a proper normal contact relation between the periphery of the transfer roller 48 and the arcuate surface of the ribs 5| of the pick-up roller 48, an adjustable abutment 9| is provided. This abutment includes a longitudinally adjustable screw 92 in intimate engagement with which the bell-crank-lever arm 35' is normally held by the spring 98, the screw 92 being carried by a lug 94 supported by the frame memberl'i.

From the foregoing description of the control device 68, and the relation of the solenoid 81 to the bell-crank-lever arm 35, it will be apparent that as soon as the switch 84 is closed, the solenoid 81 will be energized to swing the bell crank lever 34 in a counter-clockwise direction, as viewed in Fig. 1, thereby disengaging the gear 38 from the gear 41 and simultaneously moving the transfer roller 40 well out of its normal positionof contact with the arcuate surface of the ribs 5| without disturbing the contact relation between the feed breakage of the wrapper paper .I6 when a loose end of such wrapper paper might be picked .up

by the transfer roller 40 and wound thereabout, a suitable shield 05 is provided. This shield is removably supported on theframe member I1 by a pin 96 carried thereby, and is so shaped as topartially encircle the roller 40 at a sufiicient distance to permit the roller to moveunobstructedly away from the pick-uproller .40'under' the influence of the solenoid 81. I I

Removably supported on the-frame member I1, isa reservoir unit 91, adapted to carry a supply of suitable agglutinati'ng substance This reservoir unit 91 includes a pair of side plates-98, corresponding ends of which are shaped to-s nugly fit within a pair of annular grooves I00, provided in theifeed roller 3i adjacent opposite ends thereof,

the upper margins'of the walls being. extended past the feed roller, as shown in Figs. 1 and 5, to

I a position in close proximity tothe pick-up roller gate I021. Upon the hopper I01, is carried a re-' 00. The side plates 98 are connected together by a pair of transverse tie members IOI,' on which is slidably mounted a gate I02, the forward endof which, .as shown in Fig. 5, is bevelled and is adapted to be maintained in such spaced relation to the feed roller 3| as to insure the, proper quantity of agglutinating material being carried from wheel I05 and is supported intermediate its ends within a screw-threaded lug-like extension I06, carried by one of the side plates 98 of the reservoir unit 91. The gate I02 serves as the bottom wall of a hopper I01, which includes portions of the side plates 98, a pair of transverse wall sections I08 and an inclined wall section N0, the upper end of which is connected to one of the wall sections I and the lower end of which is disposed in close proximity to the upper surface of the movable receptacle I I I, having an open upper end and adapted for the reception of a suitable agglutinating material II 2, on which is buoyantly "tinating material from the container into the hopper I01. Journalled in the side plates 98 of the reservoir unit 91, is a. transverse shaft II5, which carries atone end a gear- H6 adapted to engage the gear 32 when the unit 91 is positioned as shown in Figs. 1 and 5. The shaft H is provided intermediate the side plates 98 with'one or more propeller-like agitators'l I1, which serve'to so'act on the agglutinatingmaterial as to impart to it a proper consistency and urge it-into contact with the feed roller 3|, by which it is carried from the hopper I01 through the space afforded between that roller and the bevelled end of the gamma. As the agglutinating material is carried from the-unit 01 on the face of the feed roller 3i, it isdelivered to the transfer roller 40,

from which theribs 5I of the pick-up roller-48 derive a supply of that material to be delivered 'to the wrapper paper I6 as it passes over the contact roller 65. In order to clean the arcuate surfacesof the ribs 5I of any excess material that may remain thereon prior'to'their being presented to 'the transfer roller 40 for a fresh supply, there is provided intermediate the side plates 98 of the reservoir unit 01 a scraper I I8, one end of which is shaped topresent a scraping edge, which so adjusted with respect to the arcuate surface of the ribs 5 I' as to effectively remove excess material therefrom. Anymaterial so removed from the ribs 5| is delivered along the upper surface of the scraper 8' and onto a removable closure 7 I20, suitably supported intermediate the' side plates 98 at a suflicient distance from the adjacent wall section I08 to provide ample space, as shown at I2 I through which material delivered to the closure from the scraper may pass into the hopper m1 at a point in front of the propeller-like agitators I'I1 which re-condition the reclaimed material for use by mixing it with fresh material supplied-from the receptacle II I.

Assuming that-the machine is conditioned for use, asshown in the drawings, its operation is asfollows: As'the wrapper paper I6 passes from the printing drum I4 over the "idler roller I5,

guide roller 66,. contact roller 65 and thence the hopper I01 into contact with the peripheral surface ofthe feed roller 3I, is delivered, in the form of a thin ribbon-like film, onto the-transfer roller 40, from which quantities are picked up by the ribs 5I as they move into and out of pick-up relation to the peripheral surface of the transfer roller. From the ribs M, the material is transferred to the wrapper paper I6 as it passes over the contact roller 65, any excess material remaining on the surfaces of the ribs pursuant to each transfer of material to the wrapper paper being removed by the scraper H0 and directed back into the reservoir unit 01. It will be understood that the transverse film-like coatings of agglutiof tobacco will adhere to the coatings so as to provide an annular, combustion-retarding band of tobacco particles, in union with the inner face of the wrapper of each cigarette severed, according to well-known practice, from the pencil-like cigarette structure as it emerges from the discharge end, not shown, .of the machine. Here it is to be noted that the arcuate distance from center to center of the ribs SI of the pick-up roller 48 corresponds to the linear distance from the longitudinal center line of each transverse coating on the wrapper paper I6 to the corresponding center line of the next adjacent coating, and that such *arcuate distance therefore corresponds to the over-all length of the indi vidual cigarettes, whenthe cut-01f mechanism, not shown, is timed to sever the pencil-like cigarette structure at definite intervals and at definite distances from each annularycombus wardly under the influence of the weight 82, with the result that the switch 84 is closed, the solenoid 81 is energized, the bell crank lever 34 is moved in a counter-clockwise direction, as viewed in Fig. 1, the gear 38 is disengaged from the gear 47, and the transfer-roller 40 is moved out of ribengaging relation to V the pick-up roller 48. Should the break in the wrapper paper l6 occur at such ,a point as to permit one of the ribs 5!, due to the presence of a quantity of agglutinating materialthereon, to adhere to a free end of the wrapperpaper and carry it in a clockwise direction over the pick-up roller, such" paper will be subjected to sufficient tension to cause .the knife 52 to sever it at a point following that rib, the portion so severed being thenremoved by the scraper I I8 without fouling or otherwise damaging the machine. Such severing of the wrapper paper l6 and removal of the severed portion will,

of course, occur as manytimes as a union is thus effected between the wrapper paper and the pickup roller 48 before that roller comes to rest pursuant to the automatic operation of the solenoid 81. Should the wrapper paper I6, for any reason, present a free end to the transfer roller 48, such free end is ,definitely prevented, due to the presence of the guard 95, from becoming attached to the surface of that roller with aconsequent winding thereabout of the wrapper paper.

Although the various elements entering into the present invention are accurately timed or synchronized; by resorting for example to proper gear ratios, roller diameters and so on, provision is made for advancing or retarding the points of application of the agglutinating material to the wrapper paper l6 should such points of application tend to creep lengthwise of the paper in one direction or another, for example with respect to any printing that may be, applied to the wrapper paper with the aid of the printing drum I in a manner well understood in the art. Such advancing or retarding of the points of application of the agglutinating material to the wrapper paper I6 is made possible by reason of the fact that the pick-up roller 48 can be readily adjusted to a proper advanced or a-retarded position on its sleeve 42, as conditions may require, without disturbing the position of the gear 41 by which that shaft is rotated and regardless'of whether the required correction with respect to points of application of the agglutinating material to the wrapper paper is large or small. v
