Henry H. Wheeler, flrooklyn NfYl}assignor to InternationakCigar iMachinery' Company; a corporation of: New Jersey v r 1 :Applicaticn September 5, 1934-,'SerialNo. 742,797 15 Claimsr '(ol.13 1 -3 9 p c operate. If either unit for any reasonisnot'supe InVLcigar machines; particularly those in which a plied with Ia binder. orwrapper as the, case may freshbunches are made, there are usually two operationswhich require pasting. .Ifhe first is when the bunch binder is placed on the chianti belt of the bunch rolling mechanism prior to the enclosureuof the'charge of filler tobacco therein.

pliedfto thebunchQ i H A common faultwith most paster devices now and the second when the outside wrapper is ap in use,-is the difficulty of keeping the paste clean andat an even :consistency. The pasting rollers generally employed in transferring the paste from I the paste reservoir tothe bunch binder or wrapper often conveybackihto the paste reservoir particles of tobacco which tend to clog the "operating parts ofthe'paster; .-In addition'to'i thi's source of contaminationthe paste reservoir is usually open at the top thus exposing the paste to dust and other impurities and permitting the g 20.

evaporation of the paste to 'change its consistency.

In this invention thepaste is contained in'a covered reservoir andis conveyed through a flex a the suction holes in the wrapper carrier 'or' the V 7 ible pipe communicating with "an orifice infjthe bottom-of. the reservoir and terminating ina nozzle which is positioned above .the-chiantibelt or below the wrapper carrier at the point where thei paste is to be applied. The paste is therefore not exposedjto the air until it isdeposited on the tobacco leaf section, and a more efiicient operation and a more sanitary product will be obtained.

One of the most important advances afiforded 'by this inventionjis'the automatic control." This control prevents the application of paste to the chianti belt and/or the wrapper carrier'when there is respectively noibinder on thefbunch rollin'g mechanism or no Wrapper on the wrapper V carrier, thereby making. it unnecessary to; stop the machine for the cleaning of the chiant'i belt or the carrier of paste applied thereto in the absence of the'binder or wrapper, whi'ch' has heretofore been necessary to prevent clogging of chianti belt}! While the particular system of control linkage employed maytake a great many forms, as penumatic, electrical or mechanical, in the particular'iorrn selected'for illustration, this control consists generally'of a flexible metal bellows connected to the suction line of each iunit'."

The movable end of said bellows is connected to a latch that holds the plun'gerirom forcing paste through the flexible pipe to the nozzle. :Ifa

binder or wrapperis in position; the increased' suction caused by covering ithe holes in either of these units causes the bellows to collapse, thus withdrawing the. latch. so that the. plunger can be, the unit willnot supply; pasteas--the-latch= will notreleasefthe plunger. 11-, 3*,

' 1 As the stations whereithese'operations arelper v formed are located some distance apart, and the; paste is applied "to the binder, onthe chiantibelt 4 from'ahove and. appliedto the wrapper; on the a wrapper carrier from below, it is desirabletoprovide' two pastel units; for this work. 1

when. the paste was thin, too little was'applied; In therpresent construction, an*accuratelypredeterminedyolume isa-applied regardless of con-g si'stency. nIn short -the paste is metered or-measured outby volume. I

' An objectof theinventionis to providea paster which lends itself rleadily to the application of the paste in, any desired pattern -t o the" binder or,

wrapper; In, previous; types especially those in which paste rollers v vvere used; considerable dif ficulty, was hadvin applying'any pattern excepta plain rectangular-one, except'byithe use of'grids,

Thesegrids, which dipped: in a pot and placedga vpattern on a leafportion' arranged face'rdown had limitations which mitigate against flexibility of design. For instancethe pot ordinarilyhadto be below; the grid to receivethe drippingS, ,Since different shapes of cigars requiregpasting in different-positions where the pasted portion of the wrapper is {located at the end of the wrapping operation, this necessitated moving the pot to different positions from differentf'shapes, and room iortheisa rne was sometimes difiicult to find. With the present construction adjustment is easy for various lshapes since' only the movement of: the arm and, its applying nozzle need befchanged- 1 and the pot maybe placed where most convenient.

In carrying the invention into effect there is provided a cigar bunch rolling mechanismadapted to'enclose a charge of filler tobacco in a bunch binder to form a cigar bunch,-means for applying paste toa bunch binder on saidbunch rolling mechanism, a device responsive to the absence or presence of a bunch binder on said I bunch rolling mechanism for incapacitating said binder pasting means in the absence of a binder on said bunch rolling mechanism, .a wrapper carrier operating to transfer wrappers to wrapperapplying position, means for applyingpaste to a wrapper on said carrier, and mechanism responsive to the presenceor absence of a wrapper on said carrier for incapacitating said wrapper pasting means in the absence of awrapper on said carrier. In the best constructions contemplated the binder pasting means includes a paste reservoir, a swingable conduit communicating with the interior of the reservoir and movableinto position above the bunch rolling mechanism to deliver paste to a binder'thereon, a plunger in said reservoir adapted to force the paste through the conduit onto the binder on the bunch rolling mechanism, and mechanism for actuating the plunger; and said device includes a detent operative to obstruct the movement of said plunger, and a sylphon bellows linked to said detent and connected to the suction chamber of the bunch rolling mechanism to move the detent 'out' of plunger-obstructing position when there is a binder on the bunch rolling mechanism. With the best constructions the wrapper pasting means includes a paste reservoir, a nozzle connected to the reservoir and movable into contact with a wrapper on the carrier, a plunger in the reservoir adapted to force the paste through the nozzle onto the wrapper on the carrier, and mech anism for actuating the plunger and moving the nozzle in and out of operative position; and said wrapper paster incapacitating mechanism includes a detent operative to obstruct the movement of the plunger, and a 'sylphon bellows linked to the detent and connected to the suction head of the wrapper carrier to move the detent out of plunger-obstructing position when there is a wrapper on the suction head. These various means and parts may be widely varied in construction within the scope of the claims for the particular arrangement selected to illus trate the invention is but one, of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific construction shown and described.

Referring to Figs. 1 and 2 of the drawings, the paste reservoir l l is attached to a stationary part l2gof the cigar machine. An arm I3 pivotally mounted on a boss projecting from the bottom of the paste reservoir 1 l, is connected by a balland-socketjoint Mo. to rod 14, which is also connected through balland-socket joint Ma to a lever i5 fast on shaft I511. The latter is operated from and synchronized with the main drive of the cigar machine to impart an oscillating motion to lever [5. When lever I5 is swung into the position l5 indicated in Fig. 1, the arm I3, which in Fig. 2 is shown positioned over the bunch binder BL'spread on'the chianti belt or bunch rollingapron RA of a bunch rolling mechanism of well known construction, is swung back to position l3 as indicated'by dotted lines, thus clearing the way fortheoperation of rolling the charge of filler tobacco intithe binder and spreading the next binder on the chianti belt.

While arm iii is in the full line position indicated in Fig. 2, nozzle 53a. is positioned over the bunch. binder BL at the point-where it is desired to apply the paste. it

In Fig. 5 of the' drawings the plunger i8. is shown having completed itsdownward stroke, whereby a-predetermined amount of paste P is forced through the conduit it and the nozzle 33a onto the bunch binder BL. The lowerend of plunger it slides in an orifice Hot-in the bottom of paste reservoir H and its upper end is surrounded by a spring l'ixwhich is seated between a shoulderv Etc 011' plunger 16 and the end of the plunger housing I8. .A threaded collar is which limits thedownwa'rd movement of the plungeriii, can beadiusted thereon so as to diminish or increase the length of the, stroke in order to deliver thedesired amount of paste P.

The lifting .or cocking of the plunger it is accomplished by means of a cam 29 mounted on the hubqof conduit i3, the latter being screwed on the paste reservoir .to communicate with the orifice .I to. A roller 2| on the spring-tensioned arm.22, Fig. 7, fulcrumed on the pin 23 in plungor 16 bears on cam-2i; carriedby the hub of conduit l3 and," as. the'conduit l3 swings into position over the bunch rolling mechanism, the roller"?! rides over the inclined upper edge of cam thus liftingthe plunger It with the arm 22 and compressing the spring i-i until the conduit is completes its swing and roller Eiruns off the high point 280. oncam 2%, leaving the plunger held by the detent 2d and the spring i'l compressed and ready toforceplunger l6 down in the orifice Iici whenever the same is released by the detent 2Q. Detent 24 is connected by link 25 to a sylphon .bellowsZfi which communicates with the suction chamber SC formed within the rolling tableof the bunch rolling mechanism, by means ofahose 2?. :The bunch rolling table sup ports the. bunch rolling apron RA which rolls the charge of filler tobacco in the bunch binder are all c lis'pesed to lie within the margins of; the bunch binder B L so as to seal the suction chainber-sc when the binder BL is placed in improper position onthe'apron RA. When this condition exists; the suction S is communicated through hose 2'! to sylphon bellows t (Fig. 5) causing it to contra-ct and pull the deten 24 with-it and thus render the d'etent inactive when a binder is'in place onthe'rolling apron.

y In case there should be no binder' BL on the apron, or the leaf should havebee'n notprop erly'placed, the suction is impaired suffic'ientiy to permit the bellows 25 to expand and'resiliently press the detent 24 into operative position. When this condition exists detent Y 24 will slip under shoulder 55a as plunger i6 is raisedby roller 2i on arm 22- actuated by cam 25! during the backwards'wing of the conduit l3. 'ifIhe plunger it will thusibe heldin its up, or cooked, position until a binder is properly placed on the apron,

whereupon the suction 'S w ll be restored and operate to contract the bellows 26 and withdraw the detent 2e, permitting the plunger 18 to be pr sed down into the orifice Ha, by the action of spring As plunger Iii enters the orifice Ha it causes the paste P to flow through conduit [3 and nozzle i3a onto the binder BL.

From the above description it will be seen that when there is no binder on the rolling apron,

' or if the binder hasnot been properly placed thereon, the plunger IE will not function and' consequently no paste will be wasted and smeared over the rolling apron; V v

In a cigar machinethe wrapper is usually transferred from a cutter die on which it-is'cut'from the tobacco leaf to the position in which it i's applied to the. bunch, by means of the suction head or the wrapper carrier which picks it up and] arranged that, when the wrapper carrier has come to a temporary halt,'the nozzle 33is raised .so as to contact with the wrapper WL thereon;

and at the same instant: the'plunger' 34 is released and forces paste P from the paste reser voir 3i throughtulbe 33 andho'zzl'e33 onto'the bottom of the wrapper WL. The motion for operating the paste plunger 34', as well as for raising the nozzle 33 so as to contactthe wrapper on the wrapper carrier is'de'rived from a vertically reciprocating rod 3 5, whichis connected s to and synchronized with the main driveof the cigar machine;-as will be presently described.

In 8; the paste plunger 34 is shown by full lines in cocked'position', and by dotted lines in released position; its downward movement being limited by the engagement of a c'o'llar 35 thereon with the upper end or the plunger housing 33a of paste reservoir 3!} r The cocking operation takes place dur justably clamped to rod 38, is connected td a pit man '38 on the upper end of which is secured the slotted frame 38a.

Accordingly, when there is no wrapper on the-"carrier and the paste plunger 34 is released frointhe roller 4Qc' on lever 48," in the manner,

just described, the detent 54 will arrest its downward motion and thus prevent paste from being forcedfr'ornthje -paste reservoir 3|, through tube 32 and rioz'zlefwchto' the empty bottom of the:

suctionheadof the wrapper carrier.

,In Fig.8 the nozzle 33 is shown, by full lin'es, in retracted position and, by: dotted lines, when in contact with the-wrapper on the suction head of the wrappercarrier; As hereinbefore stated, the motion for raising the nozzle into contact with the wrapper on'thejca'rrier isderivedhfrom the" vertically reciprocating rod 36."-While the rod 35' is making its up-stroke,a finger 43 thereon encounters a leverili 'which-is fulcrumed-on pin 45 in slide bracket 46. Lever 44 passes through openings in-slide bracket lfi andjplunger and, as'bracket 43 lifts lever,44,it causes' plung'er 4'5 to rise; carryingwithit the paster connections and nozzle 33..

v In order to insure contact between nozzler33 and the wrapper leafW-L on the wrapper carrier;

and'a'swa safeguard :against injury; in case. of

carelessly made adjustments, a' plunger 48;

backedby afspring lfi is arranged so as to transmit'theeffort cfle'ver' 44 to lift plunger' lhthus cushioning the contact between the nozzle 33 and the wrapper.

The top surface of nozzle 33 has a. hook-shaped narrow slit, Fig. 9, the narrow slit being shaped to conform closely to the contour of the flag end of the wrapper, in order to'deposit the' paste close to the edge at the flag end of the wrapper. 7

As the location of the suction head of the wrapper carrier and the wrapper WL thereon at the time the paste is to be applied, varies for different shapes and sizes of cigars, it is important to,

provide means for adjusting the nozzle to suit the location of the wrapper. In the present invention this feature has been taken care of by supporting the slide-bracket 46 on rods 6| which permits of shifting the slide-bracket in a radial direction and as the ends of rods 6| are attached to a bracket 52, through which plunger 35 passes, the unit can be shifted around this plunger- This arrangement therefore permits of both radial and circumferential adjustments.
