Application filed February 10, 1917. Serial No. 147,838.

To all "whom it may concern:

Be it known that I, BRITTON E. -BYRD, a citizen of the United States, residing at Durham, in the county of Durham and State of North Carolina, have invented a new and useful Machine for Making and Packing CigarettevVrappers, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for making packages of small papers of the kind which constitute a part of a cigarette.

The invention aims to provide novel means for-slitting strips of cigarette paper longitudimilly. to form ribbons, the ribbons being superposed upon each other and being inclosed in a wrapper.

Another object of the invention is to provide novel means for cut-ting the superposed ribbons and the wra )per into lengths, thereby to form the packages.

Another object of the invention is to provide novel means for assembling and collectin}: the packages.

With the above and other objects in view which will appear as the description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be'made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings 2-- Figure 1 shows in top plan, a machine embodying the improvements hereinafter described.

Fig. 6 is a fragment-a1 elevation showing the rolls which crease the Wrapper, so that the same may be engaged readily around the ribbons which are cut up to form the cigarette paper packages.

In carrying out the present invention there is provided a supporting structure including a base 1 and upstanding side plates 2 which may be shaped as required. Adjacent the rear end of the machine, the side plates 2 are connected by a horizontal platthe latch bearings 9. the reduced upper ends 8 of the shafts 7 are received. Spring washers 100 may be interposed between the upper ends of the shafts 7 and the cross bar 5, to the end that the shafts 7 may not rotate too freely. when the cigarette paper is drawn therefrom, in a manner to be de scribed hereinafter.

Mounted on the platform 3 in front of the bearings t are bearings 10. The side plates 2 are connected by a cross bar 11. Vertical shafts 12 are mounted in the cross bar 11 and in the bearings 10. The shafts 12 carry cutting instrlnnentalities. whereby the sheets of cigarette paper are cut into ribbons. The cutting instrumentalities preferably includesleeves H and cutting disks 15 alienating with the sleeves. these elements being mounted on the shafts 12 to turn thereon.

horizontal shaft lti'is mounted in the side plates 2 and is adapted to receive a roll of paper which forms a folder for the cigarette papers. Mounted in the side plates 2 and disposed above the shaft 16 are guide. rods 17. Disposed below the guide rods 17 and journaled in the side plates 2 is a roller 18. A roller-'19 is similarly mounted in the side. plates 2 below the roller 18. The roller 18 is provided. as shown in Fig. (i. with grooves 21 cmicting'with creasing ribs 20 constituting a part'of the roller 19.

In front of the guide rods 17. the side plates 2 are connected by a support 2:2. carrying a folder 23. Shafts 2+ and 25 are journaled in the side plates 2 ahead of the folder 23. The shafts 2i and 25 are provided with cooperating compression rollers 26 which rotate with the respective shafts 24 and 25. these shafts being operatively connected by intermeshing gear wheels 27 Vertically moving latch bear- I which are shown in Fig. 3. The shaft 24 may be provided at one end with fixed and loose pulleys 28, or with any other suitable driving means whereby motion may be imparted to the shafts 24 and 25, and therefrom to other moving parts which will be set forth hereinafter. Journaled in the side plates 2 in front of the rollers 26 is a shaft 29, a shaft 30 being similarly mounted, below the shaft 29. The shafts 29 and 30 are connected by intermeshing gear wheels 31. The shaft 29 carries a roller 32 coacting with a roller 33 carried by the shaft 30. The

' roller 32 has longitudinally extended cutting blades 34 received in longitudinal grooves '35 in the roller 33. The shafts 24 and 29 carry sprocket wheels 36. around which is trained a sprocket chain 37.

The mechanism above described constitutes. the means whereby the sheets or strips of cigarette paper are ut longitudinally into ribbons, the ribbons being superposed, a wrapper being applied to the ribbons, and the ribbons and the wrapper being severed transversely to form packages. The description of the machine will be tempo rarily suspended at this point, in order that the operation of the structure above alluded to may be set forth.

In practical operation, rolls of cigarette paper, indicated at 81, are mounted on the shafts 7. The paper of these rolls 81 is extended between the sleeves 14 and the disks 15,'and by the disks 15 is cut into ribbons 83. The ribbons 83 are given a quarter turn,

and pass between the rods 17 in superposed relation. A roll 84 of the paper which'is to form the wrapper is mounted 'onethe shaft 16. The paper on this roll 84 is extended between the rollers 18 and 19. The paper in the roll of wrapping 84 is considerably wider than the ribbons 83 of cigarette paper, the wrapping paper and the superposed ribbons 83 passing through the folder 23, being drawn therethrough by the coacting compression rollers 26. The ribs 20. on the roller 18, coacting with the grooves 21 in the'roller 19, crease the wrappingpaper from the roll 84 longitudinally, and the folder 23 laps the longitudinal edges of the wrapping paper over onto the superposed ribbons 83, as the'wrapping paper and the ribbons pass through the folder. By the rollers 26, the wrapping paper and the ribbons 83 are fed between the roller 32 and the roller 33, the blades 34 on the roller 32 coacting with the grooves 35 in the roller 33 to' cut the superposed ribbons and the wrapper which incloses them, into packages. At

this point it may be incidentally observed that,.in Fig. 2, a plurality of these packages 85 are shown in place in a rotatable receiver which will be described hereinafter.

Resuming the description of the machine,

it may be stated that the base 1 carries an upright support 38 at the upper end of which is located a guide 39. A slide 40 is mounted for horizontal reciprocation in the guide 39. The forward end of the slide 40 is provided with an inclined prow 41. Secured to the slide 40 is a laterally offset arm 42, the outline of which appears best in Fig. 1. The forward end of the arm 42 is beveled off vertically as shown at 43 in Fig. 3. Depending from the slide 40 is a finger 44, adapted to be engaged by the arms of a star wheel 45 fixed to a shaft 46 which is journaled in the support 38. The shaft 46 is connected by means of intermeshing beveled pinions 47 with a stub shaft 48 mounted in one of theside plates 2. There are sprocket wheels' 49 on the stub shaft 48 and on the shaft 30 of the roller 33, the sprocket wheels being operatively connected by a sprocket chain 50. The slide 40 is retracted by a spring 51, one end of which is attached to the slide, the other end of which is attached to a post 52 upstandingfrom the base 1.

' Mounted on the base 1 are standards 53 and 54, the standard 54 being provided in its upper end with a notch or keeper 55, the function of which will be made manifest hereinafter. Mounted in the standards 53 and 54 is a rigidly fixed shaft 56 on which a rotatable receiveris journaled. v

The receiver includes a pair of side plates 57 connected by a drum 58. A coiled spring and by bottom plates 61, as shown best in.

Fig. 2, the top plates 60 being somewhat shorter than the bottom plates 61. The construction is such that at intervals about its periphery, the rotatable receiver is provided with compartments denoted by the numeral 62. Located 'in the compartments 62 are compression springs 63 coacting with followers 64.

One of the side plates 57 is provided at its periphery with notches 65 receiving a holder in the form of a bar 66. Journaled on the holders 66 exteriorly of the side plate 57 which has the notches65 are rollers 67. The holders 66 are rigidly secured to the ends of the long arms 68'of bell cranks 69 Pivoted at 71 to the short arms 72 of the bell cranks 69 are pawls 73 coacting with rack bars 74 mounted to slide in guides 75 carried by that side plate 57 which is provided with the notches 65. The inner ends of the rack bars 74 are beveled as shown at 7 6. The right hand side plate 57 of the rotatable receiver (Fig. 2) is provided, as

shown in Fig. 5, with laterally extending arms 77 to which latches 79 are pivoted as shown at 78', the latches 79 swinging in openings 80 formed in the side plates 57.v

As shown in Fig. 2, the latches 79 project beyond the outer face of the side plate 57 which has the notches 65, the protruding ends of the latches 79 being adapted to coact, one after another,-with the notches or seats in the standard 54, to prevent the rotatable receiver from turning under the action of the spring 59. The beveled ends 76 of the rack bars 74 engage beneath the protruding ends of the latches 79, to permit a rotation of the receiver, in a manner which will be described hereinafter.

It has been pointed out hereinbefore that the ribbons 83 of cigarette paper and the wrapper 84 which incloses the ribbons, are severed by the blades 34 on the roller 32 to form ackages 85. These packages 85 drop one ater another into the compartment 62 of the rotatable receiver, as indicated by the arrow B in Fig. 2, and lie flat on the bottom plate 61. When a packa e has been deposited on the bottom 61 as a ove described, the slide 40 advances. The beveled end 43 of the arm 42 on the slide engages the roller 67 on the end of the holder 66 and elevates the holder, the bell crank 69 tilting on its fulcrum 70, and the arm 68 of the bell crank moving upwardly. After the holder 66 has been raised, the prow 41 of the slide 40 engages beneath the package which lies flat on the turns the said package up into a vertical position, one package after another being advanced against the follower 64, and the spring'63 being compressed. After a pack age has been deposited in the vertical position of Fig. 2, and when the slide 40 is retracted, the holder or bar 66drops by gravity into a position in front of the package, as Fig. 2 will make manifest.

Each time that the bell crank 69 is tilted vertically 'on'its fulcrum 70 by the action of the arm 42 on the slide 40, the rack bar 74 is advanced one notch. Ultimately, and

,after a predetermined number of packages 85 havebeen compressed against the follower 64, the beveled end 76 of the rack bar 74 engages between the protruding end of the latch 79, and lifts said end of the latch out of the notch or keeper 55 in the standard 54. The rotatable receiver then turns, under the action of the spring 59, until another latch 79 engages with the keeper 55. Thus, a new compartment 62 is presented to receive the severed packages from the rolls 32 and 33, andis disposed in such a position that the slide 40 may exercise its function as hereinbefore set forth.

The operation of the structure has been dealt with step by step in connection with the various component mechanisms, but,

bottom 6110f the rotatable receiver, and p briefly considered by way of follows.

By the action of the rollers 26, the ribbons 83 and the wrapping paper 84 are drawn forwardly. The wrapping paper is creased by the rolls 18 and 19 and is disposed about the superposed ribbons 83, due to the action of the folder 23. The rollers 26 advance the superposed ribbons 83 and the wrapping into the field of the blades 34, which, coiiperating with the grooves 35 in the roller 33, cut the material into packages. The packages pass in the direction of the arrow B of Fig. 2 into the compartment 62 of the rotatable receiver. The guide 40 turns the packages 85 up vertically and deposits them behind the holder 66. When rsum is as the bell crank 69 is tilted by the coopera- I tion between the beveled end 43 of the arm 42 on the slide 40 and the roller 67 on the arm 68 of the bellcrank, the pawl 73 advances the rack bar 74, and ultimately, the beveled end 76 of the rack bar disengages the latch 79 from the keeper or notch in the standard 54, so that the rotatable receiver can turn under the action of the spring 59 and present an empty compartment 62 to be filled.

The drives are as follows From a prime mover, rotation is imparted to the shaft 24 by the driving means 28. From the shaft 24, rotation is imparted to the shaft 25 by the intermeshing gear wheels 27, the rollers 26 being actuated in this manner. The shaft 24 is operatively connected to the shaft 29 by the sprocket wheels 36 and the sprocket chain 37, the intermeshing gear wheels 31 imparting rotation to the shaft 30 from the shaft 29. The sprocket wheels 49 and the chain 50 drive the stub shaft 48 from the shaft 30, and rotation is imparted to the shaft 46 which carries the star wheel '45, by the inter-meshing beveled pinions 47. The arms of the star wheel 45 cotiperating with the finger 44 on the slide 40, advance the slide, the slide being retracted by the spring 51 which is put under tension when the slide is advanced. As

hereinbefore stated, the rotatable receiver is actuated by the spring 59 when the latch 79 is disengaged from the keeper 55 in the standard 54.
