CIGARETTE AND CIGAR "WRAPPING IiEACHINE.

Application filed. June 8, 1925, Serial No. 35,593, and in Cuba January 24, 1925.

This invention is an in'iprov'ement in Wrapping machines, and more particularly in machines for entolding an assemblage of similar articles, such as cigars or ciga rettes compacted into block form, in a plurality ot Wrappers.

Cigars and cigarettes are usually coinpacted in blocks of a definite number, as for instance ten, twenty or the like, and in order to retain the moisture content of the tobacco as nearly constant as possible, it is desirable that the articles be so packed that they will not be affected by variations in humidity of the atmosphere.

This end is usually attained by enclosing the mass of cigars or cigarettes in a moisture proof Wrapper, which may be applied next to the articles, outside another wrapper or outside the hon' in which they are sometimes placed.

In order to apply the several Wrappings, a plurality of machines is usually employed, and a primary object of the present invention is to provide a machine in which a selected number of cigars or cigarettes as for instance ten may be arranged in a block or mass of regular outline, and entolded in a plurality of wrappers, one of which is of water proof material.

YVith this and other objects in ViQW, the invention consists in the construction and novel combination of parts fully described hereinafter, illustrated in the accompanying drawings, and pointed out in the claims appended hereto, it being understood that various changes in the form, proportion, size and minor details of construction with in the scope of the claims, may be resorted to Without departing from the spirit oi the invention.

in the drawings:

Fig. 1 is a side View of an embedin'ient of the invention.

Fig. 2 is a section on the line 22 oi? Fig.

Fig. 3 is a top plan View of the Wrapper magazines.

Figs. 4:, 5, 6 and 7 are perspective views shoi'ving the successive stages in the application of the second Wrapper.

In the present embodiment of the invention, a suitable support is provided, comprising a table 1., and supporting legs 2. The table supports a plurality of magazines indicated at 3 and at respectively, the magazine being at a higher level than the mag azine 3, and they ac connected to the table by means oi feed chutes 5 and 6 respectively, the said chutes extending through the top of the table as shown in Fig. 2. i

The inner Wrappers 7 are arranged in the magazine 3, and the outer Wrappers 8 in the magazine The Wrappers in both magazines are arranged with their planes vertical... A follower 9 is arranged in the magazine 8, and normally presses the mass of Wrappers toward the feed chue, and the ieeding mechanism to be described. Springs 10 are arranged between tiie follower and the adjacent Wall of a magazine 11 for cigars or cigarettes, and the end Walls oi the magazine have slots 12, through which xtend guide pins it-'3 on the follower. These pins in audition to their guiding function facilitate retraction of the follower when inserting Wrappers into the magazine.

A lever 14 is pivoted to the front Wall of the magazine .1, and the lever is positioned to engage the adjacent ends ot the pins 13, when the upper end of the lever is swung toward the magazine 11, thus to simultaneously retract the follower. Reich ring to Fig. 2 it Will be seen that the wrappers at the open or delivery sides or the magazines 3 and 4c bear at their side edges against holding eeth supported by 15,Which limit the moven'ient oi? the n this direction.

The magazine 4: also has a follower 1a"), pressing the mass of Wrappers toward the teeth, and actuated by a spri encircles the rod 18 comiected with the i lower and extending through. the outer end. of the magazine. The rod has a head shown, by means which it may be nig'iulated, to more the follower, and the lower is guided by laterally extending pins 19 which engage slots 20 in the magazine Wall.

li'iechanisn'i is provided for feeding the Wrappers in succession from the magascribed, to contact the heads with the outermost wrapper in the appropriate magazine, and afterwards move the wrapper out into registering position with the appropriate feed chute. The sockets Q l are in effect valve casings, with whichthe shafts 23 co operate as valves.

Referring to Figs. 2 and 3, it will be noticed that each socket is connected to a suitable exhausting apparatus (not shown) by conduits '25 for the upper socket, and 2G for the lower. Each shaft 23 has a lateral port 2? which is adapted when the head abuts the outermost vrapper in the appropriate magazine, to register with the inlet part 28 of the corresponding socket.

The shafts are as before mentioned slidable in the sockets, and the sockets are slotted longitudinally at their upper sides to enable the connecting of moving mechanism with the shafts. The moving'inechanism is the same for both heads, comprising an arm 29 at the top of a shaft 30, the arm being connected to the head by a link 31. Each shaft 30 is journaled in a bearing 32, extending upwardly from the table, and the shafts are oscillated bV a suitable mechanism, interposed between the respective shafts, and the drive shaft 33 of the machine.

As shown more particularly in Fi 2, eah of the feed chutes 5 and 6 extends through a wrapping channel 34 on the table 1. and through the table. Each chute has a stop 35 at its lower end, for engagement by the wrapper when it is dropped'into the chute by the suction head, and the stops are so arranged that the wrapper is held transversely of the wrappin channel, with the channel about midway or the length of the wrapper. When the ports 2'? and 23 of the respective suction heads move out of register, the pressure upon the wrappers held by the suction heads relaxes, and the wrappers fall of their own weight through the feed chutes coming to rest against the stops 35.

The cigars or cigarettes are delivered from the magazine by a pusher 36, which moves them out from the magazine beneath a plate 37. This pusher is connected in spaced. relation to a second pusher 42. hen the articles move out of the magazine, they drop onto the upper face of the pusher 412, which is longer than the pusher 36, and is in alinement with the wrapping channel 3%. When the pushers are retracted, the delivered articles drop down into. a position in front of the wrapping channel and into position before an opening The plate 37 is connected to a rod 39, by means of a lateral arm 40, and a spring ell on the rod normally holds the plate elevated. The rod has operative connections with the shaft 33 to depress it at the proper intervals. While held in such positioz' before the opening 38, another they will adhere to the flaps 46, thus clo.

pusher a2 ope ated simultaneously with the pusher 36, moves the asscn'iblagc or block dly in the wrapping channel.

assemblage of articles at the opening when the pushers 362 move forward,the assemblage is pushed through the opening 38, carrying with it the wrapper "i, into the wrapping channel. The forward movement of the assemblage folds the wrapper over the top and bottom of the assemblage, and imn'iediately adjacent the point wn .e the assemblage leaves the feed chute a folding blade l3 is arranged at each side of the wrapping channel, which folds the short flaps a l at the forward end of the package. Just beyond each blade 43 there is another blade 45,

which folds down the flaps ll and beyond each blade as there is a third blade t? which folds up the flaps all. Thus the asseml'ilage is enclosed in the first wrapper, as shown in Fig. 7, this wrapper being usually of moisture proofed material.

The pnshers 36 and 42 move together, and while the pusher 4:2 is pushing an assemblage of articles past the first series of folding blades, the pusher 36 is ejecting a second assemblage of articles from the magazine 11. This assemblage falls upon the top of the pusher 4-2, and when the pnshers retire, the assemblage will drop into position at the opening 33. Another forward movei'ucnt of the pushers moves the second assemblage into the wrapping channel, and pushes the first assen'iblage, folded into the wrapper 7, past a second series of folding blades, similar in all respects to its first series, and indicated collectively'at 419.

As the first assemblage moves toward the folding blades 4-9, it passes through a trans verse opening in the feed chute (S, and carries with it a wrapper 8. This wrapper is folded in precisely the same manner as the first wrapper, leaving the package in substantially the condition shown in 1121i nel adhesive applying mechanism is arrang to gum the flaps as, so that when loh At a suitable point in the wrapping c ing the package, and it will be noticed r ferring to F 6 that the lower end of each wrapper 3 has a tuck-in flap 51, which when the extended ends of the wrappers and 5% at the rear of the package are suitably creased will fold and tuck-in to position beneath the top flap, or it may be sealed thereon as shown in Fig. 7. This mechanism however forms no part of the invention, and for this reason is not more fully described. Suitable springs 52 are provided in connection with the chute just above the wrapping channel. The springs restrict the channel of the here to some extent, and act to hold the wrapper in proper position, during this movement into the wrapping channel.

The pushers are operated. by a disk 53 driven from the shaft 33 in any desired manner. A link 54 is pivoted at 05 to the frame, and the other end thereof is connected by a link 53 with the pushers. A pitman 57 is pivoted eccentrically to the disk and to the lever. li hen the disk is rotated, the pushers will be reciprocated.

After the packages pass the last of the second set of folding blades, the outer side flaps 58 of the outer wrapper are permitted to open, and the said flaps pass beneath adhesive applying rollers 59, which apply a line of adhesive to the flaps. Glue is applied to the rollers 59 by the mechanism indicated collcctively at 60. After leaving the rollers 59, the flaps 58 are again turned up by folding blades 61, and the completed package eventually pass from the blades 61 beneath a pressing plate 62, and into a vertically arranged receptacle.

The side walls of this receptacle are formed by endless bolts 63 supported by rollers (i l at the top and bottom of the receptacle. The inner adjacent engage the sides of the package, and they are gradually moved down through the receptacle by the plate 62. As each package passes from the folding plate 61 into the receptaclmit is pressed downward by the plate 62, which has an operative connection with the shaft 33. Eventually be wrapped packages reach the bottom of the receptacle, the travel being suiiiciently slow that the adhesive may set. At the bottom the packages pass out, dropping in succession onto an endless conveyor 64, by which they are delivered from the machine.

The shaft 33 is criven from a suitable source of power by a belt connecting the source with fast and loose pulleys 65 on the shaft. The shaft 65 drives the conveyor 64, through a countershaft 66, having mitergear connections 67 and 68 at its upper and lower ends, with the shaft 33 and the conveyor respectively. The shaft 33 also drives the moving parts of the adhesive applying mechanism, through miter-gearing indicated at The belt is shifted from the fast to the loose pulley, or in the opposite direction. by means of a lever 70, which operates the link 71, having laterally extending pins 72 for engaging the belt. The teeth of the arms 72" engage the edges of the wrappers as shown, and act to prevent removal of more than a single wrapper sheet. The arms are pivot-ed in such manner that they ncline inwardly or com ergo toward the open side of the magazine, and they are spring biased toward the wrapper edges.

Referring to Fig. 3 of the dra ing, it will be noticed that the side edges of the wrappers at the open side of the magazine ire eng aved by toothed arms 72*, pivoted 0 he magazine w lls, and urged to aid the runs of the belts wrappers by any suitable mechanism, as for instance spring. These arms serve to retain the upper ends of the wrappers from bulgingoutward at the open side of the magazine. The magazine has in addition means for engaging the tops of the Wrappers mid way of the magazine, to serve the same function. The side means is an angle bar 73, which carries at its free end a dentated plate 74.

I claim:

1. in a wrapping machine, a magazine for holding wrappers in edgewise relation, the magazine having an open side, and holding teeth at opposite edges of the open side spring biased toward the wrapper edges, and a spring urged follower in the magazine pressing the wrappers toward the teeth.

2. in a wrapping machine, a ma azine for holding wrappers in edgewise relation, the magazine having an open side, and holding teeth at opposite edges of the open side spring biased toward the wrapper edges, and a spring urged follower in the magazine pressing the wrappers toward the teeth, the teeth arranged in sets, each set supported by a pivoted arm, the arms in converging relation toward the open side.

In a machine for folding a succession of wrappers about an assemblage of cigars or cigarettes, a magazine for holding a mass of wrappers in edgewise relation, a spring pressed follower, engaging the wrappers, means to guide and support the follower including pins extending laterally from the follower, the magazine walls having slots through which the pins Xtend, and means outside the magazine for engaging the pins to retract the follower.

4.. in a machine of the class described, wrapper placing means including a suction head having a hollow shaft, a socket in which the shaft is longitudinally movable, and non-rotatable, means for moving the shaft, the socket and sh t having ports, registering when the su, 1 head engages a wrapper, and means con iected with the socket for reducing the pr J. in a machine for of wrappers about an asscmb cigarettes, a magazine for l i of wrappers in cdgewise relation. the iii-agazinc having an open side, a follower normally pressing the wrappers toward the open side, suction apparatus for removing the outmost wrapper, and means to rot n the remaining wrappers against the sue on apparatus, including sets of teeth spring pressed toward edges of the Afl'ttiQPGlS at the open side, tlr. sets converging toward said open side.
