Brooklyn, N. Y., assgnor to International Cigar Machinery Company,y aA corporation of New Jersey Application February 9, 1942, Serial No. 430,128 3 Claims. (Cl. 131-138) This invention relates to cigar machines, more particularly to mechanism for moistening,` the ends of the cigar bunches delivered Afrom the softening mechanism, prior to delivery of the bunches to the crimping or shaping mechanism. Heretofore the bunch ends were moistened, .as shown in the Halstead Patent 1,765,831, by pendent wicks suspended in the path ofthe bunch as it was carried by the transfer from the softening mechanism to the crimping mechanism; wherefore the moisture on the bunch ends was transferred to the crimping jaws of the `crimping mechanism. The moisture so applied tothe crimper jaws helps to keep the operating faces thereof free of tobacco particles which may es.- cape from the ends of the bunch Aand otherwise would accumulate and form hard lumps on the jaw faces due to the tobacco juices pressed out of the bunch during the crimping operation.

The main object of my invention is tol provide novel devices for simultaneously locating and moistening the ends of a bunch delivered from the bunch softening means, prior to transfer of the bunch to the crimping mechanism. The construction of the :locatore shown in the above-mentioned patent, which is in extensive use on cigar machines, does not permit of ro:- taton of the locators, whereas my locators revolve oppositely in a direction to wipe downthe ends of the binder which is spirally wound about the bunch charge. Moreover, moisture is transferred from moisture wells suspended from the locators by endless members, such as ,bead chains, mounted on the exterior of the locators and driven therefrom to carry moisture up from the Wells. The locators are. perforated to permit the moisture transferred by the bead chains to reach the ends of the bunch engaged by the locator. However, in the case of cigars which have straight tuck ends, it is unnecessary to moisten the tuck end ofthe cigar bunch; since with this shape of the cigar bunch there is not enough compression thereof in the crimper jaws to squeeze out enough tobacco juice to cause the particles of4 tobacco escaping from the tuck end of the bunch to form hard lumps of tobacco on the operating faces of the crimper jaws.

In the accompanying drawings:

Fig. 1 is a front elevation, partly in section, of the improved moistening mechanism associated with the softening mechanism and the bunch transfer for removing the softened bunch;

Fig. 2 is an end elevation ofthe moisteningl and softening mechanism and the bunch ltransfer viewed fromv the line 21-2 cf Fig. 1;,and.

Fig. 3 is an enlarged sectional View through one ofthe moisture wells showing the bead chain suspended in the well from the overlying locator.

With reference to Figs. land 2, the cigar bunch B is delivered from the bunch rolling apronto Vthe softening mechanism at a point A by a. bunch transfer (not shown) having a construction similar to that shown in the,l co-pending application of H. H. Wheeler, S. N. 234,001, filed October 8, 1938, and having parts'or lingers ,which hold. the bunch and enter slots 5' in the concave 'l and deposit the bunchy between the concave and the drum' IU. The bunch is rolled along the concave and manipulated and deposited at the-'position B onxcradle I4 by the rotation of thee drum whichis mounted on a shaft 51- driven in a counter-clockwise direction by mechanism hereinafter described. The concave is supported froml stationary bars I2 held inthe housingA I3. On each of the bars t2 isV clamped a support I5 to which resilient members, such as Wires I6, are clamped by a plate I'l secured to they support by a cap screwV I8. The inner lugs. I9 of the concave 1 have holes throughl which thebars I2 pass, and the ends of the wires I areclamped to thev inner` and. outer lugs I9 by plates Zsecured to the latter byvcap screws ZI. TheY cradle I4 on which the bunch B is deposited consists of curved arms 23 mounted. on'` amember` 24y fastened in and projecting from housing I3.. The bunchB resting in cradle I4 is then engagedby constantly rotating locating and moisteningheads 2'6 and' 25a, these heads being moved simultaneously in a horizontal direction towards the ends of'bunch B, as willbe presently described.,y End; less bead chains Z'I each supported in acir-cumferential groove 28 cut in heads `'it and 2cd have their lower portions submergedl in water W held in moisture. wells 29 and are thereby constantly driven to carry water up to heads 26 and 26a by chains 21, which flows through holes 30 into the conical cups 3| formed: in the locator heads which engage the ends of bunch-B. Each of the moisture wells 2-9 has a iiangeY 33 mounted on the stem of its respective locator head, each of `said stems being threaded into thehub` 35 of. gear 38.and shaft 36 respectively. Each of saidstemsxrevolves freely within vthe flanges' 33, the locator heads being screwed intothehub 35 and shaft 36 respectively, to positions where there is suflicient pla-y. between the shoulders thereof adjacent the .flanges 3-3v` to permit their stems to revolve reely'in saidflanges: As shown in Fig. 1,.thevst'em lillis'threadedintothe. hub 35, andi thet stern` of thev locator Zta isf similarly in which they encompass-fthe bunch,

26a, that is the horizontal reciprocating motion. l of the same, is achieved by mechanism which will now be described. A cam 41 has a camV track 48 engaging with a. Vcam roller 49 Apivoted Vto an operating block'50 which is releasablyl secured to the sleeve 44. Operating' blockV 50 is provided with a track 5I slidably engaging with a shoe l52 pivoted to one end of'a double lever l 53, the other end of said lever being pivotedA to a shoe 54 slidably engaging with atr'ack'55 offan -operating block 56 adjustably secured. to sleev'e`31 which carries the shaft. 36 on Ywhich the locating head 26a is'mounted. The double Alever v53 is pivoted to a stud 51a held by. aV bearinglugfof housing I3. The-blocks 50 and 56 may `be clamped or .otherwiseY securedV .to their respectivesleeves 4 4 and 31, so that upon releasing the same fromfthesleevesfthe latter maybe adjustedto position the locators to properly en:

, gage the' ends of Vdifferent lengths of bunches.vr

On shaft 46, which drives thehead 26,.' is fas-.- tened-a-gear'58 meshing with a pinion 59.which in turn is driven by a gear .60 loosely mounted.v on a stud 6I fastened in theportion of thek housing behindcam 41. The gear 6U-is securely attached to'gear 62 which isalsoloosely mounted on stud 6I." Gear 62 isA driven from a gear 63 fastened to theA cam 41. The shaft 64 of cam41 is mount,- ed in bearing lugs on'the bottom of housing. I3 and Ygear 63 is driven from the main drive of the machine.Y On shaft36, which revolves head 26a, `is fastened va gear 65 meshing with a pinion 65a mounted on a stud 66`fastened in a suitablebear-i ing lug of housing. I3. gear 61 on `the shaft 51 of drumIU, and .gear 61 by l The shaft 11 is turned to and fro through a. gear (not shown) mounted thereon and meshing with a rack (not shown) connected to and operated from a cam lever (not shown) actuated by the plate cam 80 on shaft 64. When the fingers reach the bunch B, the projecting end of the latch 13 is engaged and tripped by the adjustable.. stopscrew 82 onbar. 24, and .the spring ,closes the fingers 69 and 10 on .the bunch B to carry it ina clockwise direction to bunch shaping orY crimping mechanism (not shown).

The shaft 84 shown protruding from the housingv I3 is' slidably mounted in the latter and car- V. ries a pair of arms (not shown) both of which scribed," in the may be yieldingly mounted on the shaft 84, as dey u above-mentioned Wheeler application, On the outer ends of these arms are mounted Vrelatively yieldable fingers between Y whichlis received the bunch from the rolling apron and from between which it is deposited at the point A. 'Iheshaft` 84y yhas a gear )segment (not shown) meshingwith a gear segment on a camlever .(not shown)r operated by cam SIL-and shaft 84 also has a cam block fastened thereon and provided with aV circumferential cam track engaged by Ya stationary roller to displace lthe shaft84 axially as it carries .the bunch from the rolling apron to the softening mechanism.v Since the construction Vof the mechanism .fori oscillating and displacing axially the shaft '84, as' well as theconstruction of the arms on the shaft 84 andthe fingers supported thereon is similar 'to Gear 65a meshes .with

alsov mesheswith gear.5.lY whereby shaftY 36 is i constantly driven. kThebunch B, Vafter moistene ing heads-'Z6 and 26a have moved inland located and moistened its ends, is held between the lo, cators waiting to be moved to its'next position. This is accomplished by a bunch transferhaving a pair of ngers 69v and 16, the finger 69 having its upper end 1-I secured on shaft 12. `I'he finer ger 69 ris bifurcated and pivoted on finger 16; anda latch 13 pivoted on finger10 has a shoulder resting on a strip 14 connecting the legs` of fingers 69. A,Y tension spring 16 connected4 to a post 18 on'nger 69, andA anchored to a .post:80 on latch 13, holds the shoulder of the latch down against the plate 141to maintain the fingers 69 andV 10 in open position to admit the bunch B therebetween when they descend to a vposition finger 69 passing through' aslot in'member 24. 1 -The shaft 12 is supported in and protrudes from the outer end of la hollow arm '15 wherein it is free to revolve, the inner endof arm'15b'eing fastened to shaft `11. A bevell gear onthe inner end of shaft 12 meshes with a bevel gearon one end of a shaft (not shown) supported within and free to revolve withinthe arm 15 and having a bevelv gear (notv shown) `at its'othr end meshing with a bevel gear on shaft11',lwhereby the fingers are maintained in an upright position a'sthey that `.shown in the above-mentioned Wheeler application,.further description is deemedv unnecessary. f

Itwill be understood that other types of endless members maybe employed for transporting moisture from the wells to the locators, such as 13e Universal double jointed chain.

The construction and operation of the bunch transfer for transporting the located and moistened bunch to the crimping mechanism is no part of this invention, but forms the subject matter of the co-pending application, J. F. Halstead, Serial: No. 431,197 filed February 17, 1942. The bunch locating mechanism also forms the subject matter of Y said Halstead application.
