lNVENTOR SIGURD CLAUSEN ATTORNEY United States Patent PASTER UNIT Sigurd Clausen, Brooklyn, N.Y., assignor to International :Iigar Machinery Company, a corporation of New ersey v Application November 22, 1957, Serial No. 698,242

11 Claims. (Cl. 131-82) This invention relates to cigar manufacture and more particularly to applying paste to a portion of a cigar bunch.

One type of cigar on the market has a mouthpiece tip usually formed from wood or plastic. This type has a flat mouthpiece portion and a cylindrical portion which receives the tip of the bunch and is enfolded within the wrapper leaf. The tip is thus retained by the contained bunch tip and the overlying wrapper leaf. However, in the case of mouthpiece tips made of plastic the surface of the plastic is frequently so smooth and slippery that additional holding means are required.

It is therefore an object of this invention to apply additional holding means such as paste or glue to the top of a cigar bunch prior to the application of the mouthpiece tip and wrapper.

' It is a further object of the invention to provide a simple and inexpensive structure that may be placed on a conventional cigar machine which will receive its mo- 'tion and timing from the cigar machine and apply a small amount of paste or glue to a bunch tip at a suitable time.

. More particularly, it is an object of my invention to devise a mechanism having a source of paste or glue, and a paste applier with operating means readily connectable to a single moving part of the cigar machine and operated therefrom.

It is an object of the invention to have the device operate from a unitary motion on a cigar machine.

It is an object of the invention to have the device operate from a unitary oscillating or crank motion which may exist on a cigar machine and be related to the timed cycle of the cigar machine.

It is more specifically an object of the invention to devise a unit that may be mounted adjacent the mold turret of a cigar machine to apply paste to a cigar bunch in the mold turret just prior to its ejection therefrom.

It is an object of the invention that said device be operated from the transfer mechanism to the mold turret.

The novel features which I believe to be characteristic of my invention are set forth with particularity in the appended claims. My invention itself, however, both as to its organization and method of operation may be understood by reference to the following description taken in connection with the appended drawings, in which:

Fig. 1 is a side elevation partly in section of the paster unit shown in conjunction with rotating cigar mold turret and bunch inserting and ejecting mechanism;

Fig. 2 is a sectional side elevation of the paster unit;

Fig. 3 is a plan view of the paster unit and its actuating mechanism shown in conjunction with a cigar mold turret;

, Fig. 4 is a sectional end elevation through a single .bunch mold of the turret illustrating the paste applying (device; and

Fig. 5 is a sectional plan view showing the spring- -loaded paste transfer dipper mechanism in detail.

Referring now to Fig. 1, mold turret carries about "ice its periphery a plurality of molds 12 in which cigar bunches 14 are inserted by the transfer mechanism generally designated by 16. The mold turret is intermittently rotated in a counterclockwise direction as indicated by the arrow in Fig. 1 to cause alternate periods of movement and rest. As the mold turret is indexed each individual bunch 14 eventually arrives at the position indicated by the mold 12b. In this position it is ejected as by the conventional ejector mechanism generally indicated at 18 into the transfer jaws 20 of the transfer mechanism generally indicated at 22. The mouthpiece may be applied to the bunch 'While the same is held in the transfer 22. Since the operation of the ejector 18 or the transfer 22 does not form a part of this invention further discussion of these parts is felt unnecessary. However, the operation of these devices may be understood by reference to Patent No. 2,633,134, issued to J. F. Halstead, dated March 31, 1953, and Patent No. 2,443,453, issued to J. F. Halstead, dated June 15, 1948.

As shown in Fig. 1, the paster unit generally designated as 24 operates on the bunch 14 in the mold indicated by the position 12a. The paster unit 24 is mounted on a supporting bracket 28 secured to a flange of the turret housing 26 of the cigar machine. A bearing block 30 is secured to the bracket 28 by the screws 32. The paste reservoir 34 is supported on the bearing block 38 by the bracket 36.

Secured in a boss 38 of bearing block 30 is a stud shaft 40 on which is pivotally mounted an arm 42. To arm 42 is pivotally connected one end of a link 44 while the other end carries a stud shaft 46 fixed thereon. Secured to stud shaft 46 is also a paster finger 48, while pivotally connected to the same shaft is the free end of a suitably shaped arm 50 of a double lever 52 mounted on a stud shaft 53 rotatably supported in bearing block 30. The free end of the other arm 54 of the double lever 52 is pivotally connected to one end of an operating link 56 while the other end of the same is pivotally connected to the free end of an actuating arm 59 mounted on an oscillating shaft 158.

Mounted in bearing block 30 and projecting therefrom is a stud shaft 58 which loosely supports a suitably shaped paste supply lever 60 the free end of which is provided with a dip lug 62. The paste supply lever 60 is also provided with a torsion spring 64 which surrounds the head end portion of the stud shaft 58 and which is confined in a suitable bore in the hub of lever 60 (Fig. 5). One end of this torsion spring 64 is anchored to the head end of the stationary stud shaft 58 while the other end engages with a suitable hole in the hub of lever 60 thus urging the latter in a clockwise direction with its dip lug 62 close to the bottom of the paste reservoir 34 as illustrated in Fig. 1 of the drawings. The paste supply lever 60 is arrested at this position by means of a pin 66 projecting from the hub of lever 60 and engaging a stop pin 68 mounted in bearing block 30 and extending into the path of the pin 66. To stud shaft 53 is also secured a paste control lug 70 which is so arranged that its free end extends in line beneath the pin 66 projecting from the paste supply lever 60. Upon clockwise rotation, transmitted by stud shaft 53, control lug 70 will contact and raise the pin 66 thereby lifting the dip lug 62 of the paste supply lever 60 from the paste reservoir 34 as illustrated in Fig. 2.

It is self-evident that the entire paster unit with the connections and linkages described above is actuated in a proper timed relation by the oscillating actuating arm 59 on shaft 158 (Figs. 1 and 3). The oscillating actuating arm 59 moves in timed relation to the intermittent indexing of the mold turret. While a more complete understanding of the operation of the transfer device may be obtained by reference to the Patent to Halstead 2,443,- 453, dated June 15, 1948, the following explanation is thought sufiicient to provide an understanding of its cooperative action in the present invention. The reference numerals used herein on the transfer device are the same as those of the aforesaid Halstead patent for simplicity in comparing the two.

Transfer mechanism 16 is operated by means of a cam actuated gear segment W2 and a cam actuated arm 17%. Gear segment 102 is employed to oscillate the gear lt tl mounted on the shaft 82 to which the transfer mechanism is secured. Figure l illustrates the insertion of a cigar bunch 14- into a mold at position 120 of the mold carryihg turret 1 3. The inserting plunger shank 148 is actuated by means of an arm 156 mounted on the oscillating shaft 158 which is actuated through an arm 166 and a link 163 by the cam actuated arm 170. The latter as well as the cam actuated gear segment l'lfa, of course, are properly timed with the intermittently rotating mold turret it? to permit the plunger 14-6 of shank 148 to enter the mold at 12-? to deposit a cigar bunch 14. The oscillating motion of shaft 358 during the bunch inserting operation transmits its oscillating motion to the arm 59 which in turn through link 56 will effect the operation of the paste applying finger as well as of the paste supply lever so.

Operation Referring to the position shown in Fig. 2 the link 5'6 is at the end of its movement to the left and the double lever 52 has been rotated clockwise to the limit of its rotation in that direction. The cam lug 7% by contacting the pin 56 has raised the paste supply lever 60 to its uppermost position to permit contact of the tip of paste applying finger 48 with the dip lug 62 to effect a transfer of a small amount of paste to said paste applying finger 48.

During each dwell of the intermittently rotating turret the oscillating shaft 158 is caused to rotate in a counterclockwise direction to elfect the insertion of a bunch 14 in the mold 120 (Fig. 1). This movement transmitted by the arm 59 moves the link 5s toward the right from the position shown in Pig. 2. in turn, this causes the double lever 52 to rotate counter-clockwise about its pivot point thereby causing the paste applying finger id to swing with its free end into the mold to apply paste to the head end of the bunch as shown in Fig. l. Simultaneously cam lug 74B lowers the pin 66 down upon stop pin 65 permitting torsion spring 64 to urge dipper lug 62 into the paste pot 3 Before the mold turret it) resumes its intermittent motion shaf is turned in a clockwise direction to effect a raising of ejecting plunger from said mold. This movement is transmitted to link as to return the paste applying finger 43 and paste supply lever 69 to their original positions shown in Fig. 2, thereby completing the cycle of the paster unit in timed relationship to the movement of the mold turret.
