Figs. 15 and 16 are transverse lower presser-rolls 8, a transverse detail views illustrating the manner in which plate 9, thence down and over an idle-roller 45 the paper is folded around the filler-rod. 10, and back to pulley 4.
This invention has relation to a cigarette- Above the lower series of presser-rolls 8 machine of the class known as continuous and the belt 3 are an upper series of similar machines,wherein the tobacco is formed into rolls 8, which are journaled transversely in an upper pivotal section 10 of the frame 2, the pivotal bearing therefor being indicated at 11.
11 is an additional and larger pressureroller at the rear of the rollers 8.
2 is an adj usting-screw at the forward end of this section 10, by means of which it can be raised or lowered to regulate the vertical distance between the two series of pressurerolls, according to the amount of tobacco that is being fed. The section 10 has a downward incline toward its forward end, whereby the upper series of rolls is brought into converging relation to the lower series.
13 is a transverse steel plate which is carried by the section 10 and which is directly above the lower plate 9.
14 is a carding and distributing roller which is journaled transversely of the frame 2, just in front of the plates 9 and 13. The surface of this roller is studded with pins 15 or the like, and it is employed for the purpose of tearing or carding the tobacco as it is discharged between the said plates from the feed-belt and pressure-rolls. Both the upper and lower series of these rolls are positively driven by independent trains of suitable gear, such as indicated at 15 15. The carding-roller 14 derives its motion from the main shaft 6 by means of sprocket-wheels 16 and 17, connected by a chain 18, or by other suitable gear.
19 are guides or hopper-plates which are bolted to the feeder-frame 2, and which are for the purpose of guiding the tobacco as it falls from the roller 14 to deliver it to the rod-forming mechanism, now to be described.
20 21 designate two endless belts, which are each formed at the upper edge portion with an inward flange 22, havinga curved face 22". 23 23 designate the driving-pulleys for said belts. 24 24 are idle-pulleys around which they pass at the rear, and which are made adjustable, as indicated at 24, to regulate the tension of the belts, and 25 25 are other idlepulleys a short distance in front of the pulleys 24 24. These pulleys 25 25 are journaled at an angle to each other, as best seen in Figs. 1 and 4, whereby the lower edges of the two belts are thrown together, so that the belts form a V-shaped trough or receptacle into which the tobacco falls from the cardingroller. In front of these pulleys are two idlerollers 26, which run between the two belts in engagement with the edge flanges thereof, (see Fig. 10,) while underneath a grooved roller 27 further holds the belts to the proper position. In order that the meeting edges of the belts may be in close contact with each other, such edges are beveled or chamfered, as indicated. After the belts leave the rollers 26 and 27 they are again caused to resume their edgewise or vertical positions, being guided and held in such positions by idlerollers 28.
29 and 30 are two vertically-disposed peripherally-grooved rollers journaled in suitable bcarings of the frame and running between the lowered ge portions of the two belts after the latter have been brought back to a vertical position.
31 and 32 are two plane-surfaced transverse rollers which turn in close relation to the upper edges of the belts directly over the rollers 29 and 80, (see Figs. 3 and 7,) their purpose being to prevent the tobacco from protruding through between their said upper edges as they close upon it.
33 is an edgewise-disposed plate which is secured to the frame 1 behind the first wheel or roller 20, its upper edge projecting between the two belts and provided with a groove which conforms to the groove of the said wheel or roller. 34 is a similar plate situated between the two wheels or rollers 29 and 30, and 35 is a third plate which is placed in front of 30, ext-endin g partially over the periphery thereof. The grooves of these three plates and of the two rollers form apractically continuous chan nel for the filler-rod. It will be observed that when the two belts and the top rollers 31 and 32 are in position they form with this groove or channel a cylindrical passage which shapes the rod of tobacco as it passes therethrough under the feed, as will be more fully hereinafter described.
36 designates the paper-holding roll, which is journaled in suitable bearings, which preferably depend from the under side of the frame 1. From this roll the paper passes forward and thence upward and rearward between two parallel friction-belts 37, which run in close contact with each other and at the same speed. These belts are driven, respectively, by the pulleys 38 and 39 and run around the idle-pulleys 40 and 4.1, and are for the purpose of pulling the paper from the roll and carrying it to the folding devices. They are extremely elfective for this purpose, since they deliver the paper steadily and prevent its wabblin g back and forth, being operative with paper of different styles and grades. From these belts the paper passes between a pair of horizontal rollers 42 43, situated in front of the grooved plate 35 and which are positively driven by suitable gearing 44 and travel at the same speed as the paper. The lower roller 42 has therein a deep V-shaped groove, somewhat flattened or curved at the bottom, which gives the initial form to the paper. The upper roller 43 is complementary to the lower roller, being of double-cone form, and has in its periphery an approximately semicircular groove which assists in maintaining the shape of the filler-rod as it passes thereunder and enters the paper.
45 is a partially-grooved endless-face belt, and 46 is a straight-face bolt, the former being driven by a pulley 47 around an idle-pulley 48 and the latter by a pulley 49 around an idle-pulley 50. These two belts run parallel with each other at their working portions,
the partially-grooved one on the outside being for the purpose of folding the outer edge of the paper over the filler-rod as the latter passes through. The straight-face belt on the inside permits the inner edge portion of the paper to stand straight to receive paste from the means now to be described.
51 designates a paste-wheel which consists of a hollow cylinder which forms the paste-receptacle. This cylinder has a bot: tom portion 51 attached thereto, in the manner best shown in Figs. 6 and 11, with the openings 52 in its vertical flange 52, through whichthe paste is caused to ooze to the surface of the wheel under the action of aplunger 53 and spring 54. By adjusting a sleeve 54, which is threaded onto the lower end of said cylinder, the size of the openings through which the paste escapes may be varied and the supply of paste delivered to the exterior of the wheel regulated as may be necessary.
54 is a spring which is secured to the cylinder 51 and is arranged to engage notches in the upper edge of the sleeve 54.
55 is a roller journaled parallel with the paste-roller and in proximity thereto, its purpose being to press the standing edge of thepaper closely to the paste-roll to receive its coating of paste. The wheel 51 and roller 55 are rotated by the gear 56 and 57. It will be observed that the wheel and roller are so placed that the slight space between them is directly over the space between the belts 45 and 46, so that the standing edge of the paper readily passes between the wheel and roller.
56 and 57 are two belts in front of the belts 45 and 46 and which are similar to the latter, with the exception that the one with the partially-grooved face is placed upon the in- .side, while the one (57) with the straight face is on the outside, or the same side as the grooved belt 45. (See Figs. 15 and 16.) These four belts serve the double purpose of completely folding the paper around the fillerrod and of pulling the rod and paper through the machine, whereby all clogging is avoided. 58 isatable underneath the said belts. From these belts the enveloped rod passes to the cutting apparatus, now to be described.
' 59 designates a disk which is fastto a rotary shaft .60, journaled in suitable bearings 61, and having in its periphery a groove 62, which is in proper relation to the table 58 to receive the continuous cigarette as it comes from the folding-belts. At equal distances in said disk are cut peripheral seats 63, having guides 64 for radiallymovable blocks 65, each of which has attached thereto a strong spring 66, which is also attached to the shaft 60. Below said disk 59 is a disk 67, which has on its periphery a series of cam projec-' tions 67 of the same number and spaced from each other the same distance as the blocks 65. 68 is a slotted arm embracing the shaft and capable of a vertical movement in suitable guides 69. The lower end of this arm is arranged to contact with the cam projections 67, and its upper end is designed to contact with pins 71, one of which is carried by each of the blocks 65 and projects beyond the face of the disk 59.
68 is a spring for retracting the arm 68.
The disk 67 is carried by a rotary shaft 7 2, with which it is fast.
73 is a third disk which is journaled above the disk 59 on a shaft 74. Attached to one face of said disk is a series of bearings 75, which carry each a shaft or journal upon which is a cutter-disk 76, which is in a plane at right angles to the disks 58, 67, and 73, its edge being in close relation to the periphery of the disk 58. Said cutters are of the same number as the blocks 65, and are separated from each by equal distances.
In order to make a perfect cut, it is desirable that the cutters shall each have a rotary movement independent of their movement with the disk 73. In order to effect such movement, I cut away each of the bearing-pieces 75 and secure on the shaft or journal 7 5 thereof a grooved pulley 7 7 On the shaft 74 I loosely mount a pulley '78, which is provided with as many independent grooves as there are cutters 76 and pulleys 77in the present instance siX. From this pulley 78 I run an independent belt 79 to each of the pulleys 77. In order to guide these belts and to carry them over the disk 73,1 secure to the latter as many brackets 80 as there are belts, and in each bracket, beyond the periphery of the disk, are mounted two grooved pulleys 81. Each belt 79 in going to a pulley 77 passes over one of these pulleys 81, and in returning from 77 passes around the other pulley SI of the same set.
The pulley 78 is driven at a higher speed than the shaft 74 by a belt 82 from the main shaft, such belt having the guide-pulleys 83. By these means each of the cutter-disks is given an independent movement. It is necessary, of course, for each of the several belts 79 to slip upon one or both of the pulleys 77 78 sufficiently to compensate for the rotation of the disk 73 with the shaft. The three disks 59, 67, and 73 are all driven at the same speed by the gears 77, 78, and 79 on the respective shafts 60, 7 2, and 74, and at the same rate as the feed of the cigaretterod. The shaft 74 is geared to the main shaft 6.
The operation of the cutting mechanism will be presently described.
In Fig. 4 I haveshown a modification of the feeding mechanism wherein an upperbelt 84 is provided, running around the upper series of pressure-rollers, as indicated.
I have not as a rule deemed it necessary to describe specifically the arrangement of the gearing whereby the various rotary parts are driven,as various arrangements of such gearing may be devised by the mechanic.
The drawings indicate clearly suitable v means fordriving the various parts.
IIO
Having thus described the detailed construction of the various parts, I will now proceed to describe the operation thereof.
The tobacco is fed upon the main belt 3 in proper quantities for the subsequent operations. To facilitate this feeding, the belt may be divided off into equal spaces by a series of transverse lines. The tobacco is carried forward by this belt between the two series of pressure-rollers 8 and S, the positive movement of which will press the tobacco as closely as required, according to the predetermined adjustment. The tobacco in its continual forward movement with the belt passes between the steel platesE) and 13, which are for the purpose of getting it as close to the carding-roller as possible while still under pressure and is torn off by said roller and falls between the plates 19 into the V-trough of the belts 20 and 21. By means of this feeding mechanism the tobacco, no matter what may have been its previous condition, is properly prepared for the subsequent operations and is, moreover, fed to the bolts 20 and 21 in a regular and uniform manner. These belts again give the tobacco a forward movement as it collects in a layer of uniform thickness in the bottom of the trough formed by the belts, and it is carried by said belts over the grooved plates 33, 34, and 35 and grooved wheels 29 and 30 and under the top rollers 31 and 32, all of which shape it into a round rod. During this operation the grooved wheels 20 and 30 act as feeders. The manner in which this is performed will be apparent from Fig. 7. This rod now passes between the rolls 42 and 43, at which point it also enters the trough of the paper as the latter is shaped by action of the said rolls. (See Fig. 0.) The roll 43 now acts also to hold the filler-rod in place and to feed it onward to the belts 45 and 46. The belt 45 turns one side of the paper over upon the rod,while the opposite edge receives its proper coating of paste from the pastewheel. After receiving this coating it in turn is folded over by the belt 56 and is pasted to the other side, which was folded by the belt 45. The completely-enveloped rod as it issues from these belts passes into the groove of the disk and is carried forward until one of the blocks comes under one of the cutters 76, at which time one of the cam projections 67 comes into contact with and raises the arm (58, causing it to contact with the pin 71 of said block 65. The said block is raised by this contact and the cigarette is forced against the cutter 76 and severed. Spring 66 immediately retracts the block. As the grooved disk, the cam-disk, and the cutter-carrying disk all travel at the same rate of speed and the intermittent actions thereof take place at equal and simultaneous intervals it will be obvious that a perfect and regular cut will be made without in any way checking the feed of the cigarette-rod, which is moved continuously forward.
An important result aimed at in the abovedescribed machine is that it shall be capable of ahigh capacity or rate of production, while the parts thereof shall run at a comparatively low speed. That this is achieved to a great extent will be apparent from a careful consideration of the mechanism. As an instance of this attention is called to the fact that the cutting apparatus, which is driven at the same rate of speed as the former, folding, and feeding mechanism, need make but fifty revolutions per minute in order to out three hundred cigarettes in the same time, a rate of working which would result in an output of eighteen thousand cigarettes per hour.
I do not wish to confine myself to the exact construction and combinations of parts herein shown and described, as various changes and modifications thereof may be made without departing from the spirit and scope of the invention.
