CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 586,599, dated July 20, 1897.

Application filed May 16,1895. Serial No. 549,533. (No model.) Patented in Switzerland January 29,1894, No. 8,084; in France June 23,1894=,No.239.282, and in'lhrgland May 16,1895,N0.9,718.

To all whom, it mag concern.-

Be it known that I, FERDINAND GIRARD, a citizen of the Republic of France, and aresident of Paris, France, have invented certain new and useful Improvements in Cigarette- Machines, (for which I have obtained patents in France June 23, 1894, No. 239,282; in Switzerland January 29, 189 1, No. 8,081, and in England May 16, 1895, No. 9,718,) of which the following is a specification.

Myinvention relates to improvements in cigarette-machines, and has for its object to increase the capacity of such machines.

My improved machine is constructed to antomatically perform the following operations,

to wit: feeding the paper from rolls, distributin g the proper quantity of tobacco, molding the tobacco, wrapping the paper around the tobacco, closing the ends, and discharging the finished cigarettes.

The construction and operation of my machine will best be understood when described in connection with the accompanying drawings, in which- Figure 1 represents an end view of a machine constructed according to my invention. Fig. 2 is a side view, partly in'section, on the line 2 2, Fig. 1 Fig. 3 is a cross-section on the line 3 3, Fig. 1. Fig. 4 is an end view of the left-hand lower part of the machine. Fig. 5 is a View of the right-hand lower part. Figs. 6 to 23 are detail views.

Similar numerals and letters of reference designate like parts throughout the several views of the drawings.

The frame of the machine is composed of superposed parts 1, 2, and 3, supporting the -shaped bracket 15, secured to the front part of the hopper A. The paper passes down in front, then partly around the feed-roll 16 and between the rolls 17 and 18, which cooperate to feed the width of paper required for a cigarette. The feed-roll 17 is keyed upon a shaft turned by a ratchet-wheel actuated in one direction by a sector on a vibrating bell-crank lever 19, carrying a roller which engages the groove of the cam 10 on the main shaft (1. In

front of the feed-rolls for the paper is placed a paper-cutting apparatus consisting of two knives 20 and 21, the knife 20 being fixed, while the knife 21 is vibrated on a shaft- 32 by means of a rod 23 and a bell-crank lever 21, actuated by a cam 13. I

Dg'strt'bmion.The system of distribution isbased upon the use of a rotating measuringcup 0, fixed upon an arm 25, keyed upon a shaft (Z, supported in the upper frame 3 and actuated by a dog 26, fixed upon the hub of a gear-wheel :38, the dog 26 engaging a notch in a small crank-disk 27, fixed on the shaft (7. From the disk 2.7 motion is also imparted to a tobaecoragitatorA, located within the hopper =1, by a connecting-rod, ratchet, and bevelgear mechanism e fg, acting on a shaft to which said agitator is secured. The gearwheel 28 receives motion from the'main shaft a through the toothed cam-wheel 10 and in termediate wheel 29. The object of the use of the dog 20 is to be able by raising it to entirely stop the operation of the apparatus for distributing and agitating the tobacco. The cup 0 is placed into a receiving-chamber commnnicating with and receiving the tobacco from the hopper 4. At each revolution of the cup said cup fills with tobacco while passing through the latter and discharges the tobacco so received on the first (pladrant of its downward stroke.

In front of the vertical line passing through the axis of rotation of the cup 0 is located a series of receivers 30. (Shown on a larger scale in Figs. (5 and 7.) Said receivers receive the tobacco thrown forward bythe cup parts which pass through the tubes 32 tothe box 33 of the small frame 34, which forms a distributing-chamber, where the tobacco is evenly spread. Through this chamber passes a disoharger 35, fixed to the end of a rod 83, I00

upon the edge 31, divide the charge into two 5 guided within the frame 34 and connected to 'a groove of the toothed wheel 28 through levers 36. The object of thisdischarger is to rrapidly push the tobacco into the vertical 5 chamber B of the mold.

ll[0Zding.The molding apparatus must, during the formation of the cigarette, have a perfectly-cylindrical cavity, but must, for. the operation of distribution and discharge, be open at certain times. For this reason the apparatus mustbc composed of several .movable parts converging toward the axis when the cigarette is formed, for which purpose I have adopted the arrangement shown on a larger scale in Figs. 8, 9, 13, and 14. In

,front of the frame 34 is fixed a plate 38, notched to fit the chamber 33and extending downward to the level of the axis of the closed mold. In front of this, held at a dis' tance equaltothe diameter of the cigarette by plates 39 is secured another plate 40., the wholeforming a plunger-box. Into thevertical chamber formed by this plunger-box the active member or plunger 41 of the mold passes; It is secured to a holder 42, guided within the forward part of the frame 3 and operated-by the bell-crank lever 43, the roller of which engages a. groove of the cam 11 on the main shaft a. I

As the cigarette must be discharged at the' bottom, I have made the. lower half; of the mold in two sections or jaws '44 and 45, which are moved away to make room for the dis-' charge. This removal of the lower parts of the mold may be effected in various ways, but I shall here describe only theon'e adopted by me. I l e I The inner jaw 44 of the lower mold is fixed to thevertical slide 46, and the outer jaw 45 is fixed to the horizontal carriage 47 in such a way thatat the time of discharge the parts 41, 4'4, and occupy the positions indicated 1 bydotted lines in Fig. 8.

The two jaws 44 and 45 are actuated by. the same mechanism, consisting of a forked lever 48, the roller of which engages a groove of the cam-disk 12. It-vibrates on the-shaft 49. A bell-crank lever 50, connected to a link at the left-hand end, Fig; 3, of this lever, actuates the sliding carriage 47 with the'jaw 45, and a shaft 51 connects the vertical support 46v to the forked leverfi'nsuch 'a manner that when the jaw v44 isdep'ressed the jaw 45' moves out, and conversely.

A lever 52, vibrating in the frame 34, is operated by the faceof the cam 12. Its outer end-is forked, the prongs 53 closing the ends of the cavity in the plunger the noment tobacco is thrown upon the paper.- Between the prongs and behind the plate 38 is fixed the blast-nozzle 54, connected with the air compressor 84, actuated by cam 14,as shown in Fig. '5.

(shown in Fig. 1 and part of it on .a larger scale in Fig. 10 and Figs. 15 to 22) isarranged Wrapptng.""lhe wrapping apparatus" symmetrically in the line of the axis of the mold. It has on the right a cylinder 55, free to turn within the standard 5, but fixed longitudinally. This cylinder has gear-teeth at its inner end and is tubular in form to receive a spindle 56, consisting of a steel tube, which ispro'vided with a groove containinga Washer held by a bolt screwed through the cylinder 55, so that the spindle is connected to-the latter as to rotary motion, but capable of independent longitudinal motion imparted to it by a forked lever 58, engaging groove of' cam 8. Rotation is caused by the sector 59,-

Figs. 1 and-4, keycd to the intermediate shaft 60 and gearing into the teeth at the endof the cylinder 55, the whole being actuated by cam 9 and arm 61, Fig. 1. The wrapping device or bayonet 62 consists of a thin blade of curved cross-section, Fig. l1,s'eoured to the end of the spindle 56 in the "following manner: The bore of the end of the spindle 56 is enlarged to the internal diameter of the bayonet, split by a saw cut, and provided internallywith'a cone-thread toreceive the thread- 0 j ed end of the bayonet, a sleeve over the end of the bayonetinclosing the whole joint, the, screwing of the end of the bayonet into the. split end of the spindle forcing the latter against the inner surface of the sleeve. A set-screw prevents all accidental displacement. I g

The second part of the wrapping apparatus at'the right side, Figs. 1 and 10, consists of a v cylinder 55, toothed like'thecylinder 55 and too turning in the standard 6, but not perforated. Rotary movement is imparted to it through the sector 64, keyed upon the intermediate shaft 60, so connectedthat the two cylinders 55 and 55 move exactly alike; end of the cylinder 55 is recessed for the re-' ception of a pin '65, which leaves a space for the reception, of the end of the bayonet.

A rod 66 slid'es within the'tubular spindle '55, its end being provided with a piston 82, no

the object of which is to guard against the cigarette following the bayonet when withdrawn.- This rod 66 is connected to a counterrod 67, Fig. 1, by an arm 68 and actuated by cam 7 and lever 69.

. FOZding.-The closing of the ends of the cigarette is eifected by two organs acting one after the other, the first of which I Call folders and the latter fingers.

The *folderfm'ech anism consists of two. ver I20 ti'oal sliding rods 70, Fig.-l,"connected bya ,cross-head 71, into the end of which engages a lever 72, Figs. 1 and 2, receiving motion from the cam 73. 'These rods 70 are only the intermediate organs for transmitting motion. I215 The folders proper, 74, (shown on a larger scale in Fig. 9 and-Figs. 19 to 22,) are mounted 'on' the front part of the frame 34 and on both sides of the mold-channel. Their operative ends are dressedto a special, and they have 1 0' curved slots engaged by fixed guide-pins 75 and 76. The folders are connected to the sliding rods -70"by links 77. On the spindle 56 there is a stop 78, Fig. 2, secured to. the

The inner.

sliding rod 70, its object being to slightly deflect'the bayonet when entering the mold to preventthe latter buttingagainst the countermold.

The finger mechanism consists of two horizontal arbors turning in horizontal bearings on the mold-support 46. The axis of rotation of these two arbors is a little lower down than the tangent passing through the bottom of the counter-mold 44, so as to force the paper into the openings formed at the ends of the latter when closed, Figs. 19 to 22. Upon the cord of the arbors (on the side of the coun ter-mold) are fixed the finger-holders, opposite thereto two conical pinions, to which motion is imparted from two sectors fixed laterally upon shaft 79, Figs. 2 and 3, actuated by cam 13 and an arm with a roll likewise upon shaft 79 and engaging cam 13. \Vhen the mold-holder -:t6 descends, the fingers bear against the sectors and through the pinions make one revolution, which assists the discharge of the cigarette.

Operation. The hopper being charged with tobacco and the paper-r011 in place, the paper is passed between the feed-rolls. The machine is then operated to open the counter-mold, the plunger rising again, but not yet uncovering the bottom of the distributingchamber, the prongs lowered, the paper advances sufficiently for one cigarette, the counter-mold closes, the plunger rises to the end of the stroke, while the bayonet enters the opposite cylinder. The discharger then rapidly pushes the tobacco into the vertical channel and causes it to fall upon the paper. The plunger redescends and compresses the tobacco. At this instant the shears cut the paper, while the prongs rise to completely uncover the ends of the mold. The bayonet then makes its rotation, wrapping the paper around the tobacco, and the central rod advances to permit the withdrawal of the bayonet by holding the cigarette in the mold. Toward the end of the movement of the bayonet the central rod recedes to make room for the folders, which descend to make the first fold and reeede at once, while the fingers turn the folds in and at once resume their former positions. The wrapping of the cigarette is more clearly illustrated in Figs. 15 to 18. The paper, as shown in Fig. 15, is fed forward su-fliciently to overlap a portion of one side of the mold, while the bayonet enters beneath the paper and lies against one wall of thecounter-mold. After the tobacco is compressed in the mold, as shown in Fig. 16, the bayonet rotates in the direction shown by the arrow in Fig. 17. At the commencement of said rotation the edge of the paper is caused to fold over the bayonet, as shown in Fig. 17', and the paper is then carried with the bayonet. The revolution of the bayonet continues until it reaches the position shown in Fig. 18. The plungerthen abuts against the tobacco andthe bayonet is withdrawn, leaving the cigarette rolled and its ends free from tobacco for a short distance to permit the same to be closed up. The folders 74 now descend and turn a portion of each end downwardly and inwardly, and then rise again. The fingers 71L, made tapering and triangular in cross-section, turn in the direction of arrow 7, Fig. 19, and turn the lower half of the paper upwardly and inwardly, as shown in Fig. 21. The counter-mold opens then while the air-compressor discharges a strong jet of air upon the finished cigarette and throws it out. As soon as the plunger in its descent has cleared the bottom of the distributing-chaml'ier the dischargcr recedes to allow the tobacco projected by the cup to fall down for the next cigarette.
