INVENTOR GEORGE DEARSLEY ATTORNEY Patented Apr. 17, 1951 PAS-TEE FOR CIGAR'ETTE IMAKING MACHINES George Dea'rs'ley, Scarsdal'e, N. m; assig nor to American Machine &'Folmdry Company, a corporation of NewJers'ey Application J db 9, 1949, Serial No.'1i)'3,853

- 1 This invention relates to paste applying apparatus for cigarette making machines and more particularly to an improved mounting for a paste supplying nozzle.

It is the present practice to extrude a continnous stream of starch paste from a nozzle having a slot which rides against the concave face of a wheel sometimes referred to as a marble wheel. Ithas been found that starch paste tends to ooze o-ut between the seal formed by the nozzle and the marble wheel'unless the fit is particularly close. To obtain a close fit between the nozzle and the marble wheel requires much time. Even after a close fit has been obtained the nozzle and marble wheel sometimes get out of alignment again when the nozzle pressure against the wheel is adjusted to feed paste properly due to the deflection of the supporting member. At the end 'of each working day and sometimes during the day, the paster nozzle may be removed for purposes of cleaning. When the nozzle is replaced, much time is again frequently lost in properly aligning the nozzle with the marble wheel.

It is therefore an object of my present invention to overcome these alignment problems by providing a mounting which willallow the paster to be readily removed for-purposes of cleaning and which will allow it to be accurately replaced at the end of the cleaning process without its getting out of alignment with the marble wheel.

Another object of my invention is to provide a mounting for the nozzle of a cigarette machine paster which will be self centering with respect to a marble wheel when pressure is applied to the nozzle.

' Afurther object of this invention is to pro vide a slidable mounting for a-nozzle which permits it to be readily located over the center of the marble wheel.

Another object is to provide a mounting for the nozzle of a cigarette machine paster which will be so arranged that any deflection that occurs as a result of increasing or decreasing the pressure against the nozzle will not aiTect the relative position of the nozzle to the marble wheel so as to break the seal therebetween.

Other objects and features of the invention will appear as the description of the particular physical embodiment selected to illustrate the invention progresses. In the accompanying drawings, which form a part of this specification, like characters of reference have been applied to corresponding parts throughout the several views which 'make u the drawings.

Fig. 2 is an end elevation taken on the line 22 of Fig. '1.

in the embodiment used to illustrate the invention a gear housing HI and the cylinder supporting bracket 12 secured to the frame I4 of a cigarette machine by a suitable means such The worm I6 is driven from the main shaft of a cigarette making machine and imparts driving movement to the worm gear [8. Teeth 2B are formed'on the hub '22 of the worm gear I 3 and constitute part of a conventional toothed clutch. Similar teeth 24 are formed on the hub 26 of the hand wheel 28 so that driving movement of the worm gear l8 will be "imparted to the hand wheel 28 through the

teeth

22 and 24 which comprises a toothedv type clutch.

"The hand wheel 2 8 has a key 30 which slidingly engages with the keyway -32 formed along the length -of the threaded teed screw 34 so that the hand wheel "28 and screw 34 rotate together. A cap '36 is mounted -or1-'one end of the threaded screw 34 and on the other end of the threaded screw '34 is mounted the piston 38. The threads of "screw '34 meet with the threaded hole 48 formed in the supporting bracket 12 so that when the hand wheel 28 is rotated either through the worm gear E8 or manually, the screw 34 will raise or lower the piston '38 depending upon the direction the screw 34 is rotated.

Piston 38 is arranged to move up and down inside or a cylinder 42 which contains a aste P such as starch. The lower end ofthe cylinder '42 has a cap -44 to which is attached a flexible paste conveying tubin 46 while the upper end of the cylinder 42 has a flange 48 secured thereto which supports the cylinder from the top of the bracket I2.

-'Cyli-nder '42 is held firmly in bracket l2 by a hinged-clamp '50 which is locked in closed position by means of a winged nut 52 pressing against thelugs 56 formed on the hinged door 50. The nut 52 is threaded on a hinged bolt 54 which It will thus be seen that when downward movement is imparted to the piston 38 through the screw '34 paste will be forced through the flexible paste conveying tubing 46 to the paste applying memberBB. Conventional nipples '60 and H are employed for connecting the tubing 46' with th cap 44 and the member 58.

The member 58 has a hub 62 which is pivotally Stud 64 is fixedly secured to and projects from the framework of a cigarette making machine. Paste is forced through a duct 66 formed along the length of the member 58 which connects with a transverse hole 68. A cover plate 18 is secured to the member 58 by means of suitable screws 12 and has a deflector stud 14 which deflects paste from the hole 66 to the hole 68.

The discharge end of the nozzle casting 58 is provided with a nozzle 13 which has a convex surface 19 which rides in contact with the concave periphery 15 of the marble wheel 16. The convex surface 18 is kept in contact with the marble wheel 16 by suitable means such as the adjusting screw 18 having a lock nut 88. Adjusting screw 18 is threaded in the lug 82 which projects from the frame of the cigarette making machine. It will be noted that the adjusting screw 18 is substantially in line with the plane of rotation of marble wheel 16 and when the screw 78 is set the lines of force will be substantially in line with the center of the marble wheel 16. Any twisting action would occur in the screw 18 and not in the nozzle 14. Therefore there would be no tendency to break the seal between the face of the nozzle 14 and the marble wheel 16 as often occurred heretofore when the pressure of the nozzle against the marble wheel was adjusted.

It will be further noted, as seen in Figs. 1 and 2, that the hub 62 of the member 58 is slidably and pivotally mounted on the stud 64 so that the nozzle 14 is free to move transverse to the plane of rotation of marble wheel 16. This permits the nozzle 14 to automatically center itself with respect to the marble wheel 16 when pressure is applied and prevents the nozzle from having any tendency to tilt. To obtain the best results the screw 18 should be preferably adjusted when the cigarette machine is running.

Marble wheel 16 is mounted on shaft 84 which is driven from the main shaft of the cigarette making machine. A paste applying transfer wheel 86 is provided for removing paste from the periphery of the marble wheel 76 and transferring it to the seam L of the cigarette rod R. The transfer wheel 88 is driven by the shaft 88 from the main shaft of the cigarette making machine.

The operation of my invention may be briefly described as follows:

Prior to starting the cigarette making machine in operation the cylinder 42 is removed and filled with paste. This is accomplished by lifting the hand wheel 28 upwardly to disengage the

toothed clutch

24 and 28 and then turning the hand wheel 28 counterclockwise until the piston 38 has reached the upper limit of its travel. After releasing the nipple 6! from the cylinder cap 44 the wing nut 52 is then unscrewed so that the bolt 54 can be swung outwardly to release the lugs 56 of the hinge clamp 58.

After the cylinder 42 has been cleaned and refilled with paste it is replaced in the supporting bracket l2 The hinged door 58 is then closed and the bolt 54 is swung into place and the nut 52 tightened against the lugs 56 to hold the door 58 in place. The cylinder 42 will be then suspended by means of flange 48 from the top of bracket I2 and the hinged door 58.

Nipple 68 is then secured to the member 58 as shown in Fig. 1. By rotating the hand wheel 28 clockwise the piston 38 will move downwardly until it comes into contact with the paste P in the cylinder 42. Hand wheel 28 is then lowered to engage the toothed-

clutch

24 and 28.

When the cigarette machine is in operation it causes the worm IE to rotate slowly which in turn imparts rotary movement to the worm gear [8. Through the teeth 28 engaging with the teeth 24 the hand wheel 28 is rotated. By means of the key 38 the feed screw 34 is rotated forcing the piston 38 to move downwardly which in turn causes paste to flow through the flexible tubing 46 into the

ducts

66 and 68 of the member 58. The rotating marble wheel 16 receives paste extruded through duct 68 and orifice 11 of nozzle 18 and carries it to a point where the periphery of the transfer wheel 86 picks up the paste and deposits it on the lap edge L of the traveling cigarette rod R.

The paste extruding nozzle casting 58 may be readily removed and replaced as follows:

Lock nut 88 is turned counterclockwise to release the adjusting screw 78. Adjusting screw 18 can then also be turned counterclockwise thus removing pressure from the cover plate TI. After unscrewing nipple 6| from the cylinder cap 44 the operator merely has to slide the hub 62 off the stud 64 to release the member 58 so that it may be cleaned.

To replace the member 58 the operator slides the hub 62 over the stud 64 and moves it inwardly until the orifice ll of nozzle 13 is in the center of the marble wheel 15. Adjusting screw 18 is then turned clockwise to press against the cover plate 78 to hold the nozzle 13 against the concave surface of the marble wheel 16. When the adjusting screw 78 is turned to apply pressure to the member 58 the lines of force will pass through the center of the nozzle contacting surface 14 and the concave surface of marble wheel 15 thereby avoiding any tendency for either of these members to twist. Since the hub 62 is slidably mounted on the stud 64 it permits the nozzle contacting surface to automatically seek the center of the concave surface of the marble wheel 76 when the latter starts to rotate.

It will thus be seen that I have provided a mounting for the nozzle of a cigarette machine paster which is adapted to be not only quickly removed for purposes of cleaning but which can be quickly replaced without loss of time and .properly align itself when the machine is started.

As just mentioned since the lines of force are in direct alignment there is no tendency for the nozzle to twist when pressure is applied which results in paste escaping between the marble wheel 16 and the convex nozzle surface 14.

While applicants invention is especially Well suited for use with a starch paste which may have a relatively high viscosity it is obviously also adaptable for use with a paste such as casein Which may have a lower viscosity. The primary feature of applicants invention consists of the particular mounting and arrangement of the paste applying nozzle which permits the same to be quickly removed and replaced without an op- 'erator encountering any difficulties in aligning the paste applying nozzle 74 with the marble wheel 16.
