Application iledv .Tuly 16,'

To all whom t may concern.:

Be it known that I, lViLLrAiii FgGRUPE, a citizen of the United States, residing at Hudson Heights, county of Bergen, State of N ew Jersey, have invented certain new and useful Improvements in Tipping Mechanisms for Cigarette-Machines, of which the following is a specilication.

This invention relates totipping mechanisms for cigarette machines and is particularly directed to types of machines for ing tipping material to cigarette paper preparatory to or combined with the making of cigarettes. l

An object of this invention is to provide a simpliiied form of mechanism for feeding tipping material to an indefinitelenhgth of cigarette paper, and'to afliX the individual tips to the paper at distances corresponding to the cigarette strength.

A further object of the inventionk is to provide a tipping mechanism capable of attaining higher'certainty and a gree of speed of operation.

A further object of the invention is to provide a tipping mechanism of-suiiiciently reduced over-all to be readily attached to approved typesv of cigarette making machines.

A further feature` of the invention is to ranged to positively feed the tips to the movy ing paper strip in registry with the paper strip. In the more preferred forms of the invention, my tipping mechanism is applied tol-approved types Of cigarette machines and is disposed anteriorly of the tobacco feeding hopper and comprises a rotating drum to which the indefinite length of cork or other tipping material is continuously fed, rotary; severing` means cooperating with said drum for cutting the cork to the desired length or width of the tip, such drum being provided with suitable means for positively retaining the separate tips 4and feeding the tips successively to and in registry withthe paper strip fed to the cigarette machine, pressure roller means for applying successively the cork tips to the indefinite length of cigarette paper, means for moving the transporting drum and pressure rollerimeans with the cigarette paper and preferably at substantially the same Speedo-f feeding of the ciga- Specification of Letters Patent.

of aflixing the cork tips thereto, and mechanism governing the operation of the aforesaid elements of the tipping mechanism'in correspondence to the locations of aiiixing the .cork tips to the cigarette paper, as required' by the diii'erent lengths of cigarettes.

Further features and objects of the invention will be more fully understood from the following description and the accompanying drawings, in which- Figure is a side elevation of a form of tipping mechanism embodying my inven.

tion, partly broken away in vertical sectional elevation yto show hidden parts; and

Fig. 2 is a sectional elevation on line 2-2 of F ig. 1 as viewed in the direction of the indicating arrows.

rThe vparticular form of the invention as illustrated in the drawings is applicable to approved types of cigarette making machines, the main frame of which is indicated at 1, the usualhopper at 2, the usual cigarette tobacco feeding chute at 3 and at 4 the roller for guiding the strip of cigarette paper 5 into vthe chute 3. During the passage of the cigarette'paper 5 through the chute 3 the cigarette tobacco is heaped in the regulated amount, all of which is well understood by the art in the practice Ofoperating approved types of cigarette making machines and need not be further described herein.

My tipping mechanism, Vindicated generally at 6, comprises the frame 7 having' the feet 8 adapted to be bolted or otherwise secured to the lower Ybed 9 which may be a rearward extension of the main frame 1 of the cigarette machine. Such frame 7 of my tipping mechanism is provided with a dovetailed head 10 serving as a support and gui'de for the reciprocating table 11 supporting the cor r feeding drum 12.

The'drum 12 is iixedly mounted on the shaft 13 as by means of the key 14 and the shaft 13 vis mounted in the u 15, 16, secured to the reciprocating table 11.

n they under face of the reciprocating table 11 is'se'cured the rack 17,the teeth 18 of which mesh with the teeth 19 whose radial arm 26 is fixed to and at an angle to the arm 21 having' the boss 22 piv- Oted onthe stud 23, carried in the block 24 secured by the boltsv 25 to the bed9 of the spaced bearings of the segment cigarette machine. The arnn'26r of thesegment is guided by the cam roller 27, pivotally carried thereby and coacting with the [cam 28 mounted on the shaft 29, 'ournaled in suitable bearings carried by-'tlie. opposite - sidefframes 7, 7. The shaft 29 and cam 23 are rotated in the direction indicated by the l being sub arrow 30, seeFig. 1. The rise of the face of thecam 28. is indicated at 31, comprising a single region of 27 radially from the center lineof the shaft 29, theremainder of the face of the cam 28 tantially circular with gradual rise and fall from the circular contourto the raised lportion 31.

ing and oscillation stages ofthe movements' of the drum 12. Y

The location of first contact-of thev cork` strip 56 with the' drumk 12 is indicated at 65. The circular or effective face 66 of the drum 12 is provided with sets of perforations67 serving as air passages,say in sets of four passages `arranged in substantial alinementl transversely to the circumferential direction of the face 66 of the drum'112, combiningV with suitable air exhausting means matically feeding and vretaining the cork. As one form of pneumatic vmeans lhave 'shown the hollowY sector block 69 h'aving`the outlet passage 70, see Fig.A 2, communicating with the. tube` 71 leading tonany suitable air exhaust fan, pump, orequivalent, the direcf i tion of. flow of the air being arrow 72, Fig.` 2. Such block 69 lis ,furtherV -providedwith the passagev 7 3'coimnunicatf indicated lby thev ing with the clearance ,74 extending annu through ,the region ofsevering the cork strip into cork tips and to la location slightly beyond the region of afiixing the cork'tips to the cigarette paper 5,' as will appear `hereinafter; Such block 69 is secured to the fixed 11, whereby the-block sitioned relatively to the table 11.V At the 1 anterior edge 7 5. and posterioredge 7 6 of the block 69, a substantial seal iis made between thek block 69 and the innerfperipheryfof the,v perforated face 66- of the drum 12 against leakage of air. Y

Suchpneumatic means correspondsgen#l` erally to thepneumatic means shown and described inmy copending;l application 55e-,y rial No. 310,361, filed by meV on July 12, 1919, and entitled T 'pping mechanism. l The gum fountain llarly from the location 65 ofthe drum 12, x l

shown) having suitable the setnut l68 Vtapped into arms 67 (one only slot for receiving the side of the bed 9. The gum roller 54 may be of the gravity type, as by mounting its oppositely disposed shaft 60 (one only shown) in the slot 61 of its hanger arm 67a.

Suitably associated with" the retaining drum 12 I have provided the severing drum 7 8 driven, say, in the direction of the arrow 9 by.. means of its gear 80 suitably driven by the gear 81 fixed on the shaft 13. The particular severing devices of the severing' drum 78, as shown, comprises a series of knife blades 82 spaced from one another peripherally about the'drum 78 and preferably provided with spring pressure ymeans and having the generalconstruction shown and described in my vaforesaid copending application Serial N o. 310,361.

' ccordingly, upon drive of the drum shaft 13' by the aforesaid driving means, the gear 81 causes the gear 80 to rotate and z thereby to rotate the severing drum 78,

whereupon its knife blades 82 successively sever the strip 56 of cork into individual corp tips which are retained by the aforesaid pneumatic means on the periphery 66 of the drum 12 and transferred upwardly in the direction of the arrow 68 `toward the cigarette paper 5 and the pressure roller 83.

T e vpressure roller 83 may be suitably mounted on the operating lever 84 pivoted the arm 86 of the lever 84 being' provided with the cam roller 87v coacting with the cam 88, pinned or keyed to the shaft 29 driven as aforesaid by the skew gear 32, such lever 84 being tensioned by the retractilespring 89 to hold the cam roller 87 in continuous contact with the effective face of the cam 88. The direction of rotation of the cam 88 is indicated by the arrow 90, see Fig. `1.

The severing drum is preferably provided with the brush or wiper 91 shown mounted adjacent the severing drum 78 and opposite to the retaining drum 12 and driven by a suitable gear, not shown, meshing' with the gear 92, in turnmeshing with the gear 80, whereby the bristles of the brush 91 are driven in direction of the arrow 90, z'. e.,

counterl to the direction ofI movement of the knife blades 82.

The cam 88 as shown, is provided with a single raised portion indicated cam roller 87 n tact therewith, at whichr stage the lever 84 is oscillated, and roller 83 bodily oscillated in clockwise direction as viewed in Fig. 1, causing the roller 83 to be' forced toward the retaining' drum 12. The roller 83 is shown freely mounted on its vshaft carried by the upper end of the lever 84, but may be positively driven by any suitable means.

'of or provided with an outer Preferably, the roller 83 is entirely formed annular face of compressible rubber or the like, to provide an area contact, rather a line contact,

of the table 11,v

with the upper face of the cigarette paper during' the stage of affixing a cork tip to the cigarette paper.

It will be noted that the distance from the gumming roller 54 to the location 65 of the retaining drum 12 is considerable and of an extent to permit the applied gum or adhesive to be seasoned and the cork properly permeated, preparatory to gumming the cork tip to the cigarette paper, thereby obviating any excessive moisture or liquid constituent of the adhesive whereby the paper might be weakened in tensile strength. f

It -will also be noted that the face of the cork strip 56 to which the'adhesive is applied is` the face which is not in contact with the periphery 56 of the retaining drum 12, thus obviating the transfer of the adhesive to the effective face 66 of the feeding drum 12. e

The individual cork tipsare applied to the underside of the cigarette paper 5 as is indicated at 94.

It will be noted that the pneumatic means of they drum retains the severed cork tips in definite, spaced relation on the surface of the drum and upon the continued rotation of the drum the separate cor: tips are successivelyfed to and in registry with a oigation ofv pressule of the pressure roller 83 5, whereas the cigarette tip indicated at this stage at 95 is periphery 66 of the retaining drum 12 and its adhesiveapplied face against the under face of the`A cigarette paper 5. n

From the' above the operation of the tipping mechanism `will be largely understood and the following should planation of the the right hand end of the with the right hand end of the dovetailed head 10, thence toward the left `until it attains its substantially central position shown in Fig. 1 and continuing farther to the left to its extreme left hand position at which last named'position the lefthand end of the Y head 10.v

The combined speed of bodily reciprocation and rotation of the drum 12 during its stagey wlien'the cork tip' is being affixed to the paper strip is substantially equal to .the

, speediof feeding of the cigarettepaper into speed of travel of the drum tips, andthe period of each referencev to specific vforms Y stage of affiXing the number of cork.. severing the cigarette machine.

,lt will be understood that gearing of the operating parts of my tipping mechanism may be selected to Veffect two or moie complete reciprocations of the cork transferring drum for each revolution 'of the operating cams and tationally substantially yequal to r of feeding of the cigarette paper the cork tip to the cigarette the speed papera... v I v Preferably, each corlrportion 94 corre-. sponds to a double tip, and accordingly is of twice the dimension `along the length of the cigarette rod of that of a single-tip, and the severing of the cigarette rod by the rotary knife is effected midway vof the cork portion 94, to form two tipped cigarettes.

lliflit is desired to apply single tips by means of my tipping mechanism, eachcork portion V94; is of a single tip, and the distance on the cigarette rod of the successive tips 94;;i`s one-,half thatin the case of double full reciproca tion of the table lland of each y blades 82 doubled, whereas the speed of rotation of the drum -12 for feedingV and supportingthe tipping materialis unaltered, as compared with the mechanism described hereinabove. y Vhereas l have described my invention by thereof, it will that many changes and modifications may be made without departing from the spirit of the invention, as defined by the appended claims. v, l claim.: l, 1.
