APPARATUS FOR MAKING A BUNCH Filed Sept. 13, 1938 5 Sheets-Sheet 5 ATTORNEY Patented May 27, 1941 APPARATUS FOR MAKING A BUNCH Joseph W. Giles and William J. Giles, Philadelphia, Pa., assignors, by mesne assignments, to Jersey Cigar Machines, Inc., Belleville, N. J., a corporation of New Jersey Application September 13, 1938, Serial No. 229,658

12 Claims.

The object of this invention is to devise apparatus for making a bunch charge which will mechanically produce a bunch charge having greatly improved characteristics.

When a bunch charge is formed by hand in the making of the best grades of cigars, the operator attempts to lay the tobacco straight along the longitudinal axis of the mass and builds it up in this manner in layers until the proper size of bunch charge is attained.

Our present invention enables one to obtain a greater degree of accuracy and excellence than it is possible to do by hand, since the uncertainty of the human element is eliminated.

In carrying out this invention, a loose batch of tobacco of greater quantity than required for a bunch is removed from the hopper, as in our prior Patent No. 2,118,505, May 24, 1938, and falls down a chute, separating and loosening the tobacco and discharging it into a charge receiver, having grooved feed rollers. Any excess tobacco is removed from the mass in such a manner as to still further loosen and separate the parts of the bunch.

The feed rollers have only a short feed so that a small amount of tobacco at a time is pulled down from the charge in the charge receiver. The charge is now subjected to straightening operations and this can be accomplished due to the small amounts of tobacco being fed at a time from the charge receiver.

When the pusher is returning, the tobacco is falling on the top plate of the pusher. This has a tendency to straighten the tobacco and move it against a baffle plate above the pusher and acts to straighten the tobacco.

As the pusher moves forwardly, any pieces of tobacco positioned diagonally will be straightened by the pusher pressing against a corner or end of a strip of tobacco; As the pusher moves forwardly, the tobacco is moved against a discharge plunger slide giving the tobacco a further tendency to straighten out. The tobacco is now in a sizing box leading to the bunching apron, and is pushed down into such box by a sizing plunger which has a further tendency to straighten the tobacco.

The charge is supported in the sizing box on a sizing member resiliently held in position, so that, as soon as the proper amount of the charge is on the sizing member, the latter will trip, arresting the feed of any more tobacco. The sizing box and plunger slide moves downwardly and the charge is discharged into the rolling apron which applies the binder in any conventional manner.

In so far as We are aware, We are the first in the art to make a bunch charge in this manner with the tobacco in a loose, spongy form, with the portions of tobacco extending longitudinally along the longitudinal axis with an absence of twisted and compacted pieces of tobacco, so that the cigar when finished will have an easy draft and be free smoking from the tip to the butt. 7

We eliminate the necessity of using the conventional cut-off knife, which at times, particularly when the knives are dull, passes through the tobacco, and drags the stems or veins without cutting them from the mass of tobacco and disarranges the entire bunch.

With the above and other objects in view as will hereinafter clearly appear, our invention comprehends a novel apparatus for making a cigar bunch.

It further comprehends novel means for intermittently and positively feeding small portions of tobacco to build up a bunch of small overlapping layers; novel means to effect the straightening of the particles of tobacco to cause them to extend in a loose condition along the longitudinal axis of the bunch without being twisted or compacted; novel pusher means; novel plunger means and a novel construction and arrangement of two timed crank mechanisms which control all of the feeding and sizing mechanism.

It further comprehends novel feeding means in the form of grooved rollers having means to intermittently actuate them.

Other novel features of construction and advantage will hereinafter be clearly set forth in the detailed description and the appended claims.

For the purpose of illustrating the invention, we have shown in the accompanying drawings a preferred embodiment of it, which, in practice, will give satisfactory and reliable results. It is, however, to be understood that this embodiment is typical only and the various instrumentalities of which my invention consists can be variously arranged and organized, and the invention is not limited to the exact arrangement and organization of these instrumentalities as herein set forth.

Referring to the drawings:

In our prior patent for Tobacco feeding ap paratus, No. 2,118,505, we have described and broadly claimed a novel construction for re? moving a mass of tobacco from a hopper and delivering it to a chute, and since this same feed is employed in our present invention, we have illustrated and described such construction in only suflicient detail for the understanding of those skilled in this art.

The tobacco container l of the machine has a shaft 2 journalled in it and driven in any desired manner, for example, by a motor 3, driving a sprocket chain 4, passing around a sprocket wheel 5, on the shaft 2. The container is open at the top to receive the tobacco which is-removed from the container by a scoop 6 on an arm I fixed to the shaft 2. The tobacco is discharged from the scoop, as the shaft 2 revolves, into a chute 8.

T e fore o ons u n is the same as that of our prior patent aforesaid.

The tobacco receiver The chute discharges the tobacco to a tobacco receiver 9, see more particularly Figure 3. The bottom of the receiver 9 has a plate and sides H are secured tothe receiver which has an upwardly extending side plate l2 which forms a throat leading to the chamber of the receiver. The upper end of the receiver and its rear end are open.

A leveling member I3 is disposed between the side plates Hand is in the form of a plate having its lower marginal portion preferably irregular or serrated. The member I3 is for moving excess tobacco back into thehopper and is fixed to a lever l4, fulcrumed at Hi to a portion of the frame I5. A link H is pivoted atone end to the lever-l4 and at its opposite end to a rock arm l8 fixed to a rock shaft l9 journalled in the,

machine frame If, see Figs. 1 and 2.

The shaft I9 is rocked by a cam fixed to the shaft 2, it being seen that such cam, see Fig. 1, cooperates with a roller 2| on a lever 22 fulcrurned at 23 and connected by a link 24 with an arm 25- fixed to the rock shaft l8.

Tobacco aligning mechanism The tobacco is moved from the tobacco receiver 9 by a pusher 26 in the form of a fiat plate deflected downwardlyatits forward end. The pusher 25 has lugs 2} extending into slots 28 in the sides of the tobacco receiver. The pusher 25 has a rod 29 on which links 35 are loosely mounted, said links being. fixed to a rock shaft 32 journalled in the frame and controlled by a novel crank mechanism which will now be described.

The motor 3, see more particularly Figure 8, has a worm gear 33 which meshes with a worm 34 on a shaft 35 connected with a shaft 36 by a clutch 31. The clutch is controlled in a conventional manner by a foot treadle 38 operatively connected with the clutch to actuate it.

The shaft 35 has a pulley 39 fixed to it and around such pulley passes a belt which also passes around a pulley 4| on a shaft 42 journalled in the machine frame I6, see Figures 1 and 2. The shaft 42 has a worm 43 which meshes with a gear 44 on a crank shaft 45 journalled in the machine frame. The crank shaft 45 is driven at a higher speed than the drive of the shaft 2. The shaft 45 has a crank arm 46 connected by a longitudinally adjustable link 41 with one end of an arm 48, the other end of the arm 48 being fixed to the rock shaft 32 to rock it and thereby reciprocate the pusher 23, see more particularly Figure 3.

The U shaped plate [2 cooperates with a front plate 49 and a rear plate 50 to form a tobacco receiver, and the juxtaposed wall of the tobacco container or hopper I is deflected as at 5| to overhang the plate 55. The bottom of the tobacco receiver is closed byserrated feed'rolls 52 and 53, see Figure 3, suitably journalled in the side plates l I of the tobacco receiver 9, see Figure 6. The shafts of the feed rolls 52 and 53 areintergeared by the gears 54 and 55, see Figure 6. The feed rolls 52 and 53 are intermittently driven from the crank shaft 45. The shaft 32, see Figure 3, has a rock arm 56 fixed to it, and to the free end of the rock arm 56 is pivoted one end of a link 51 pivoted at its opposite end to a lever 58 fulcrumed on the shaft of the feed roll 53, see Figures 6 and 7. A driving pawl pivoted on the lever 58 has a spring 55 which tends to move the hooked end of the pawl towards a ratchet 5i fixed to the shaft of the feed roll 53, see Figures 6 and'7. 52 is a stop pawl having a spring 63 tending to move it towards the ratchet 50. will thus be clear that the feed rolls at the bottom of the tobacco receiver are intermittently actuated by the crank 45.

The crank shaft 45 has a crank arm 64, see Figure 3, which is connected by a longitudinally adjustable connection 65 with a link 66 fixed to a rock shaft 61 to which is fixed an arm 68 having at its forward end a depending sizing plunger 59, which sizes the tobacco delivered by the pusher 26 to a reciprocatory sizing box H1 since it presses on thetobacco in the box and when the charge is sufficient it presses the tobacco against a sizing plate hereinafter described;

open at the top and bottom and has the front wall at its lower end cut away as at H and the rear wall at its lower end slotted as at 12-, in

order to receive a rockable tension bar or plate '13 which at its free end is slotted as at 14, so that the bottom of the sizing boxtwill be closed during the sizing operation, see Figure 4. The front wall of the sizing box is formed by 2. rectangular plate l5, see Figure 11, which has a depending'extension 15 forming the front of the sizing box, see Figure 11. The rear wall of the sizing box is formed by a U shaped plate 11 which has the slots 12. The plate is secured to a casting i8 having side flanges 19 which carry rollers 85, see Figure 11, which travel in guide slots 3| in the main frame, see Figure 2.

The sizing box is reciprocated by meansof a link 82 pivotally connected at its lower end at 83 to the casting 18 and at its upper end to a lever 84, see Figure 1, fulcrumed at 85 and having a roller 86 which rides in a cam groove BI'ofa cam 88 fixed to the shaft 2. The tension bar 13 is offset and fixed to a rock shaft 89, at one end, see Figure 2, and at its opposite end is pivotally mounted on a rod 90 carried by the machine frame. The rock shaft89 has an arm 9| to which is connected one end of a spring 92 the opposite end of which is connected with a fixed portion of the frame, so that the tendency of such spring is to retain the tension bar in its raised position as shown in Figure 4.

Discharging mechanism for the sizing boa:

The sizing box I0, see Figure 11, has guides 93 secured to its plate 15 by fastening devices 94. These guides receive the ejecting plunger 95 having a rod 96 connected by a longitudinally adjustable link 91 with a lever 98 fulcrumed at 99 and having a roller I which rides in the cam groove 81, see Figure 1.

Automatic clutch control One of the side flanges 19 of the sizing box mechanism has a block |0| secured to it in spaced relationship, see Figure 11, and this block IOI is slidable in a slot I02 in the machine frame, see Figures 9 and 1.

The block I 0| travels in the path of a roller I03 on the rock arm 9| fixed to the shaft 89 and its spring 92 connected with it and a fixed point ends to retain such rock arm in its raised position against an adjustable stop I04, see'Figures 1 and 9. The rock arm 9| acts as a stop and release for a link I pivoted at its upper end at I06 to the machine frame and having a spring I01 tending to move it towards the rock arm 9|. The lower end of the link I05 is pivoted to one end of a bar I08 having a slot I09 into which a pin II 0, carried by a lever III, extends. A spring 2 tends to rock the lever III on its fulcrum II3, see Fig. 3. The lever III has a lateral extension II 4 having reversely inclined walls 5 and 6 which cooperate with a pin M1 on a lever II8 having a clutch arm II9 to actuate the clutch I on the shaft 42, see Figure 3. The lever I I8 and clutch arm I I9 have a common pivot, see Fig. 3. The arm 4 is connected by a link |2|, see Figures 1 and 3, with a lever I22 fulcrumed at I23 and having a spring I24 tending to retain its cam shaped end I25 in the path of a roller I26 carried by the cam 20.

.The rock arm 9|, see Figure 9, has a roller I21 which contacts a rock arm I28 pivotally supported at I 29 and having a cut out forming a shoulder I30 so that when the arm 9| is rocked downwardly the shoulder I30 will move the lower end of the link I05 above such arm 9|. A spring I 3| tends to retain the rock arm I28 in raised position as seen in Figure 9. The rock arm I28 has a cam face I32 with which a pin I33 00- operates, see Figure 2. This pin I33 is at the end of a lever I34 fulcrumed at 61 and having a link I35 connected with a lever I36 fulcrumed at I23 and having a cam I31 in-the path of travel of a roller I38 on the cam 20.

The lever III, see Figure 3, has an outwardly deflected end I39 which is in the path oftravel of a cam I40 on the crank shaft 45, see Figure 3.

The operation will now be apparent to those skilled in this art, and is as follows:

The tobacco is placedin the tobacco container I and the motor 3 is started, thereby revolving the shaft 2 and the arm 1 causing the the tobacco receiver 9.

scoop 6 to remove tobacco from the tobacco container and discharge it into the chute 8 as set forthin my prior patent.

The tobacco discharges from the chute 8 into The parts are so timed that the cam 20, see Figure 1, now rocks the lever 22, thereby link 24, arm 25, arm I8, link I1, and thereby lever' I4 to move the scraper I3 rearwardly and return excess tobacco to the tobacco retainer I. The tobacco is now in the tobacco receiver 9 ready to be intermittently fed in small quantities to the aligning mechanism by the feed rolls 52 and 53.

The motor 3 through worm gear 33, see Figure 8, drives worm shaft 35, clutch 31, shaft 36, pulley 39 and belt 40 to drive pulley 4| and shaft 42, see Figures 1, 2 and 8. The shaft 42 is intergeared with crank shaft 45 to drive it, see also Figure 3. Crank arm 46, through adjustable connection 41, see Figure 3, rocks arm 48 to rock shaft 32 and thereby rock arm 55 to raise and lower link 51 and thereby reciprocate lever 58 and by the pawl and ratchet mechanism, see Figures 5, 6 and '1, to intermittently turn feed roll 53 and thereby feed roll 52 intergeared with the feed roll 53. The feed rolls are serrated so that as they revolve they withdraw small quantities of tobacco from the tobacco receiver 9. The tobacco being discharged strikes an inclined baffle I 4| which tends to align the particles of tobacco and is received on the top plate of the pusher 26 which at this time is in its forward position. The pusher 26 now moves rearwardly and the particles of tobacco are further aligned by engaging the baffle MI. The tobacco now falls on to the plate I0 and is ready to be moved forwardly by the pusher 26.

The forward movement of the pusher further aligns the particles of tobacco due to the small quantity of tobacco fed at a time and its contact with the pusher, the plate I0, and the wall of the sizing box.

As the shaft 32 rocks, as before explained, the lever 30, see Figure 3, is rocked on its fulcrum, thereby moving a layer of tobacco into the sizing box 10 above the tension bar 13.

A layer of tobacco is fed into the sizing box, the sizing plunger 69 moves downwardly to press each layer downwardly towards the tension plate 13. The size of the bunch charge produced by repeated accumulations of tobacco is determined by the height of the plunger 69 above the tension plate. The height of the plunger 69 can be adjusted by adjusting the link 65. When suflicient tobacco is in the sizing boxto complete a bunch charge, plunger 69 presses the bunch charge against the tension plate to size it and to move the tension plate downwardly. The layers of tobacco accumulate until the mass is of such size that the plunger 69 presses the accumulated mass of tobacco against the tension plate to move said plate downwardly.

The crank arm 64 through the adjustable link 65 rocks thelink 66, rock shaft 61, arm 68 and the sizing plunger 69, During this sizing opera-' tion of the sizing plunger 69, the parts are in the position seen in Figure 4. I

' The rock arm 9| is fixed to shaft 89 on which one end of the tension plate is mounted so that when the tension plate 13 rocks downwardly, under pressure of the plunger the rock arm 9| rocks downwardly, thereby permitting link I65 to move in due to spring I01 to release the clutch I20. The. operation is such that crank 64 causes the return of plunger 69 to raised position before cam I40 goes into operation to disengage the clutch. The cam I40 is so timed that the plunger 69 is now in its raised position and does not interfere with the movement of the stop plunger 85. When link IE5 movesin, it rocks lever III through link I98, thereby moving the deflected end I39 into the path oi'the cam I40, which causes the lever III to raise arm II8 to move clutch arm H9 to disengage the clutch.

The sized tobacco is now ready to be discharged into the pocket of the rolling apron I42, seen in Figure 3.

The plunger 95 now descends and the sizing box moves downwardly and the tension member I3 is moved out of the way by the downward movement of the sizing box to permit the bunch charge to be wrapped to drop into the pocket of the rolling apron.

Roller 86 riding in cam groove 81 of cam 88 rocks lever 84 to actuate link 82 to move the sizing box downwardly. Roller I in cam groove 81 causes lever 98 to rock to move downwardly link 91, rod 55 and plunger 95.

The rolling apron is actuated by a lever I43 in the manner well known in this art and forms no part of. our present invention.

When the rock arm 9| rocks downwardly, due to the, plunger 69pressing the tobacco against the tension plate, the link I draws bar I08 forwardly, turning lever III, see Figure 3, in a direction to bring the end I39 into the path of the cam I45 with the lever resting on the stop pin II'I, When lever III is turned by the cam I40, arms H8 and H9 are moved to actuate the clutch, the clutch collar of which is spring pressed. The releasing cf th clutch stops the crank shaft 45 which isout of operation during the period in which plunger 95 is moving the bunch into the pocket of the rolling apron. When the sizing box I is in its downward position the block IGI holds the rock arm 9| in its downward position, thereby holding the tension plate out of the path of the plunger 95.

As the shaft 2 revolves and thereby the cam 20, the roller I26 rocks lever I22, raising link I 2I, see Figures 1 and 3, thereby rocking lever II I to draw bar I98 rearwardly, drawing I39 out of the path of cam I40, permitting spring 42 to cause reengagement of the clutch, and link I85 assumes the position seen in Figure 9. a

As cam 2!! revolves, roller I33 rocks lever I36 to move downwardly link I35 to rock downwardly lever I34 causing pin I33, see Figure 2, to rock arm 9| downwardly and also rock arm I28 so that link IE5 is moved inwardly to retain rock arm SI in its downward position the amount of tobacco in the sizing box being sized before the machine makes a complete revolution. Near the end of such revolution as the cam 20 revolves arm 9| is returned to its starting position. Block IflI moves upwardly allowing arm 9I to assume its raised position due to the action of spring 92.

This acts as a safety device, so that the feeding and sizing operation are interrupted during the discharge of a completed bunch from the sizing box;
