RUPERT E. RUNDELL, F ROCKVILLE CENTER, NEW YORK, ASSIGNOR TO AMERICAN MACHINE & FOUNDRY COMPANY, A CORPORATION 0F NEW JERSEY y CORK-TIPPER FOR CIGARETTE BIACHINES Application filed 'March 22, 1930. Serial No. 438,192.

rI`his invention relates to an improved tipping mechanism to be usedvin conjunction with continuous rod cigarette machines, its main object being toproduce a device suitable for operation at high speed by means of a continuous feed of the tipping material.

With this and other objects in view, the invention consists in certain constructions and combinations which will be hereinafter lo fully described and then set forth in theappended claims.

The cork or other tip material strip is fed from a reel over a guide plate by two contacting rotating rollers and is cut by a revolv- S ingknife blade. The latter is clamped on a disk supported by a shaft mounted at an angle to the cork stripso that the revolving knife blade travels with the'y continuous -f running cork strip while cutting, and thereby secures a straightcut. A ledger plate fastened to an arm which receives its motion from the said shaft follows the rotating knife blade. The cut piece of cork, constituting the tip fortwo cigarettes, is clamped between two rotating rollers around one of which passes the paper Lor other wrapper material strip to be tipped, and is thereby fed lengthwise onto the continuous paper strip. The c-igarette paper is led by a guide 3o between a pair of rollers which apply paste to the paper at equal intervals by means of properly spacedv peripheral projections ony one of them, the said projecting surfaces engaging a paste drum before contacting with the paper. The paper, so prepared, is carried around one of the clamp rollers heretofore mentioned in such a manner that the incoming cork tips register with the paste y spots on the paper strip, and, after having 10 picked up the tip, is then led around another drum and finally passes into the cigarette machine. In passing over the last mentioned drum, the tipped paper strip lies with its cork tips against the drum surface, so as to keep the tips under pressure While thepaste is drying.

The paste may be applied either to the paper by an intermittent contact device as described, or it may be applied to the cork by passing the latter over a rotating continuous paste surface before its entrance into the .tipapplying clamp rollers. In the cork tipper shown in the accompanying drawing, the paste is applied to the paper.

`In the accompanying drawing which forms a part of this specification and in which like characters of reference indicate the same or like parts:

In carrying the invention into effect, there is provided means for applying adhesive to separated portions of cigarette wrapper material, means for continuously feeding a strip of tip material, means for cutting the strip of tip material, and means for applying the severed strips to the adhesive portions of the wrapper material. In the bestconstructions contemplated, the cutting means includes a rotating knife detachably secured to a disk carried by a shaft inclined to the horizontal plane and a reciprocating ledger plate cooperating with the knife and supported by a ca m operated slide. In the best constructions contemplated, also, the adhesive applying means includes a transversely adjustable pivoted guide, relatively adjustable paste carrying and applying drums, and an adjustable scraper cooperating with the former. In the best constructions contemplated, also, the means for continuously feeding the tip material includes an adjustablev guide and cooperating rollers for feeding the strip, and means for applying the severed strips to the adhesive portions of the wrapper material including a pivoted framey and relatively ad- V95 justable rollers carried by said frame. These various means and parts may be widely varied in construction within the scope of the claims, for the particular machine selected to illustrate the invention is but one of 10c sov many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific construction shown and described.

Referring to the drawing, the cork tipper mechanism consists of the cork feed shown in Fig. 2 and at the left in Fig. 1, and of the paper feed shown in Fig. 3 and at the right in Fig. 1. The former is driven from a jacksh'aft 10, while the latter receives its motion from the main shaft 11, which, together with the j ack-shaft, are parts of the cigarette machine.

Jack-shaft 10 carries a spiral gear 12 meshing with a spiral gear 13 mounted on shaft 14 to which is fastened a spiral gear 15 meshing with a spiral gear 16 mounted on the inclined knife drive shaft 17.

To shaft 17 is also fastened a spiral gear 18 /meshing with a spiral gear 19 mounted on shaft 20. The latter shaft carries also a spiral gear 21 meshing with a spiral gear 22 mounted on shaft 23 which has a spiral gear 24 meshing with a spiral gear 25 on shaft 26. Shafts 23 and 26 carry the rollers 27 and 28, respectively, through which the cork is fed. Knife drive shaft 17 is supported in bearings 29 and 30 mounted in housing 31, and carries a knife disk 32 provided with lugs 33 supporting pivot 34 on which are loosely mounted clamping lingers 35 having the shape of bell crank levers and clamping with one arm the knife blade 36 to the disk 32, and engaging with the other arm a recess of clamp-bushing 37, the bore of which is threaded and engages with the threaded hub of disk 32. ln turning the clamp-bushing 37, the clamp lingers 35 will clamp or release the knife blade 36, see Fig. 4. In order to hold the clamp fingers 35 and the knife blade 36 in any desired position, the end of shaft 17 is threaded and is pro-vided with a lock nut 38 by which the clamp bushing 37 is locked in position.

Knife drive shaft 17 carries the cam disk 39 engaging with rollers 40 and 41 pivoted on studs 42 and 43 mounted on slide 44 which is supported in housing 31 and guided by plates 45. The cam disk 39 is so constructed that, when revolving,the slide 44, which is engaged through rollers 40 and 41, will receive reciprocating motion corresponding with the forward movement of the tip material and knife blade 36, and impart it to the Y arm 46 provided on it which carries the ledger pla-te 47.

i The cork strip C, supplied from a reel, is guided into rollers 27 and 28 by guide plates 4 8 adjustably mounted on stud 49 supported by housing 31. After the cork leaves rollers 27 and 28, it is guided by brackets 50 mounted on housing 31.

The paper feed is driven from main shaft 11 carrying a spiral gear 51 meshing with a spiral gear 52 mounted on shaft 53 which is supported in bearings 54 on frame 55. Shaft 53 carries a spiral gear 56 meshing with a spiral gear 57 on shaft 58 supported in bearings 59 of frame 55. Spiral gear 57 meshes with spiral gear 60 mounted on shaft 61, and spiral gear 60 meshes with spiral gear 62 mounted on shaft 63 which is supported in bearings of the paste pot 64 and carries the paste drum 65.

The paste pot 64 is provided with lugs 66 and 67 and supported, through studs 68 and 69, by frame 55. Stud 68 is provided with a clamping nut 70, while stud 69 is eccentrically mounted so as to provide adjustment for raising and lowering of the paste pot. The paste pot 64 is provided with a scraping plate 71 mounted on pivot 72 carrying arm 73 having adjusting screw 74 resting on stoplug 75 by the! tension of a spring 76. A turn of the adjusting screw 74 brings the scraping plate 71 closer or farther away from the paste drum 65,'thereby controlling the amount of paste carried away by the latter. Shaft 61 carries the paste-applying roller 77 having equally spaced peripheral projections 78, so arranged that the peripheral distance from they center o-f one projection to the center of the neXt is equal to the length of two cigarettes, the whole circumference of the roller, in the case of twoprojections shown, being equal to the length of four cigarettes.

On the shaft 58 is mounted a roller 79 placed at such distance from shaft 61 asV to press the running paper strip P into contact with the paste-carrying projections 78 of rollers 77, thereby applying paste to the strip P at the proper intervals.

The strip so prepared is carried around the roller 80 against which bears a companion roller 81, the said pair of rollers being so placed that the distance of their center line from the knife 36, when in cutting position, corresponds with the length of one cork tip. By this means the leading end of the tip severed from the cork strip is engaged by the rollers 8O and 81 at the instant the tip is completely severed from the cork strip. Each tipat the instant it is completely severed is thus clamped between the rollers 8O and 81, and is pressed upon a paste spot on paper strip P as it is carried forward by the movement of the rollers. The paper strip P with its so attached cork tips C is carried around a drum 82 mounted on shaft 53, with the cork-tip side toward the drum, so as to press the cork tips firmly to the paper strip while the paste is drying.

Sha-ft 53 carries a spiral gear 83, driving, through intermediate gear 84, a spiral gear 85 meshing with spiral gear 86. Gear 85 is mounted on stud 87 carrying the roller V81. Gear 86 is mounted on stud 88 carrying roller 8O and adjustable by means of adjusting screw 89 through which roller 80 can be termediate gear 84 is mounted on stud 90 on which is swingably supported a double lever arm 91 carrying on one end the studs 87 and 88. The other end of armV 91 has a pivot 92 engaging with adjusting screw 93 which is supported by bracket 911 attached to frame 55. By turning adjusting screw 93, arm 91 swings on stud and brings rollers 80 and 81 nearer to or farther from the cork feed, thereby permittingV the adjustment of the length of the cork tip.

The incoming pap-er strip `P is guided by a guide plate 95 supported by bracket 96, adjustably mounted on

studs

97 and 98. Stud 97 is provided with a spring 99 and an adjusting nut 100 so as to provide lateral adjustment.
