, The present invention is forimprovements 1n or relating to cigarette making'machmery, and more particularly toa device for applying adhesive to a travelling web ofcigarettef 5 paper'fed through a cigarette making ma` v chine of the continuous rod type, and has for its Object'the provision of a device in which` the 'receptacle for the adhesive may be removed and a duplicate substituted therefor 104 without necessitating any delicate adjustments to "any part of the device. Y

There -hashitherto been used vuponv .cigac rette making machines of the continuous rod4 type al device wherein a receptacle'adapted i 15 to receive adhesivev is mounted upona oiga` rette making machine in suchfa manner that ra plunger movable in the receptacle is adapted to force adhesive through a'nozzle formed in one end of the receptacleonto the surface 20 'of a furnishing roller from whichtheadf4 v Y hesive' is taken by a rotary wheel whichap-r` plies the `same to va rette paper.` f l n o lVitha device ofthe abovecharacter, however, it is essential'thatthe*mouth ofthe noz-` zle in the adhesive receptacle and the surface of the furnishing iroller shall it veryj accurately together so as to ensure that the adhesive is fed correctly from the rece'p'liaiizle 30 to' the surface of thefurnishing roller.'

This requiresvvery accurate fitting and'also necessitates line adjustments y beingk made travelling/Web of ycigaj every time the receptacle isremoved forre-4 vfiiung 'H 3D The present invention consists of a device Y for applying. adhesive to-a travelling web of cigarette paper which comprises in combinar fiona receptacle adapted to accommodate ad-` i. 40V hesive (for lexample starch), a plunger operable to force the'adhesivethroughan out-'y "le t opening formed in the said receptacle, a.

Referring tothe drawings, a receptacle ll adapted to contain starch paste or like adhesive is carriedjuponfa v'standard 2 mounted y The receptacle -1 is adaptedA to ybe detachably securedbymeans of a bayonet joint V3 ard 2.- plunger 5 carried by a screw thi'eaded' yrod 6 is continuously'moved downwardly an outlet opening '7 formed in thel lower end tatedby a pulley 10 driveran' from theV main o The spindle S carries Y spindle i sleeve'lis adapted to rotate ona cylindrical of raV dogjclutch'," 17. vAuscrew" threaded holle i8 ,ed f@ Slide over the threadedgpod' e, 9 but ,isz prevented fronr rotating relatively o A le Y- a* pieceio'fudealableifleii i e Y nozzle 20.formedwi`th a con-v cavefsurface 201 'arranged to engage with the:v peripheryof a furnishing roller 21 having a thereof. a 'lrphesurface in which the nozzle is 2g y n 1,782,180

formed is maintained in an accurate position relatively to the furnishing roller so that the supply of adhesive to the said roller is constant and the position of the nozzle need not 5 be Varied or altered once the machine is set.

A paste applying Wheel 22 is adapted to engage. With the periphery of the furnishing roller and Atransfer' pasteto the `edge "olf a travelling web of cigarette paperQB. 10 When the machine is operating the plunger 1 5 forces the adhesive through the tube Taffand the nozzle 20 in a regular stream so as to supply a film of adhesive to the furnishing roller; l v 21. As soon as the piston has reached the y 15V bottonrof the receptacle 1 ,the operator lifts*` the collar 18 on the rod` and` ,clamps .the f samefthus b'reakingthe dog clutch connection so'that the rod `6 ceases 4to rotate andthe piston remains stationary; The `operator f 0' then disconnects the union 24 and rotates the rod 6 by meansof the hand WheelQ untilthe iston 5 isat the top oflits strokewhereupon a full pot of paste is substituted.

ItA Will be seen therefore that very little n `5&5 timeis lost in changing the paste receptacle as it is not necessary Vto disturb the accurately set nozzle and furnishing roller. Y If desired, a shearing pin or a similar de-V vice ma be fitted to the driving pulley l()V ,-430 so that m the case of any obstruction occur-v ring, the pin vbreaks and no damage is done p' to the mechanism. n What vI claimV as myinvention and desire to secure by Letters Patent is ze' n n Y Inadevice for applying adhesive, the coini' bination With a receptacle having an aper- Vture at one end thereof through which adhesive may be introduced and discharged, a

` piston movable in said receptacle toward the "40 apertured end thereof `for discharging adhesive from `the latter, a threaded ,piston rod associated with said' piston, a franieon Awhich Y said receptacle is Y removably supported,
