CIGARETTE-MACHINE.

SPIEICIIEICATIOIii` forming part of Letters Patent No. 553,507, dated January 28, 1896. Application led April 26, 1895. Serial No. 547,228. V(No model.)

To @ZZ whom, zit may concern;

Be it known that I, WILLIAM C. BRIGGS, a citizen of the United States, residing at Tinston, in the county of Forsyth and State of North Carolina, have invented certain new and useful Improvements in Cigarette-Ma chines, of which the following is a specifica tion.

My invention relates to what is known in the art as the continuous-filler class of cigarette-machines, in which loose fibrous to-y bacco is automatically fed into the machine,

formed into a continuons filler-rod, and inclosed in a continuous wrapper which is folded around the filler-rod, pasted and then sealed, forming a continuous cigarette, and then cut into smokable lengths by automatic cutting mechanism.

My present invention contemplates the production of a continuous cigarette by the performance of these operations in a simple and effective manner by certain novel combinations, constructions and organizations of instrumentalities which are hereinafter particularly designated.

The best way now known to me of carrying out the objects of my invention is to feed the tobacco to rollers or brushes, between which it is passed, and which deliver it in regulated quantities directly upon the grooved flanged periphery of a main carrying-wheel, which (3o-operates with another flanged carryingwheel, the two wheels being so organized as to cause their iianges gradually to converge from the feed to the discharge end, so as to compress the tobacco laterally and cause it to pass beneath a wheel or roller, the periphery of which is grooved correspondingly with the main carrying-wheel so as to compress the tobacco into circular shape, form it into a llerrod of uniform dimensions, and deliver it upon a paper strip, which is carried by an endless belt through suitable folding or wrapping mechanism to a suitable pasting and sealing device, and thence to the cutting devices.

The accompanying drawings show so much mechanism embodying the improvements herein claimed as is necessary to illustrate my invention as adapted to a machine substantially resembling, in many respects, that shown in Letters Patent No. 512,151, granted to me January 2, 1894. Some of said improvements, however, may be used without the others, and in machines differing somewhat in their details of construction from that herein shown. Unless otherwise indicated the parts are supposed to be of usual approved construction.

My invention contemplates the adaptation of my improvements to the best machines of the present day.

The feed end of the machine I term the front-,. and the discharge end the rear That side of the machine on the right of one adjacent to and facing the front I term the right,7 the opposite side the left. In this instance the right side of the machine is that on which the operator stands.

Figure 1 is a plan or top view of the entire machine. Fig. 2 is a left-side view thereof in elevation, or an elevation of that side opposite the operator; Fig. 3, a vertical transverse section on the line 3 3 of Fig. 2, looking toward the front or feed end of the machine, showing the tobacco feeding and carrying mechanism, Figs. 4, 5, and 6 are on an enlarged scale. Fig. 4 is a plan or top view of the filler forming and carrying wheels and a portion of their driving-gearing. Fig. 5 represents a plan view, partly in horizontal section, through the feed side of the fillercarrying wheels, showing their relation at that point. Fig. 6 represents a similar view in section through said wheels and the compressing-wheel at the opposite or delivery side of the carrying-wheels, showing their relation at this point and the mode of insuring uniform speed between the filler-carrying wheels. Fig. 7 represents a similar detail view of the ller-carryin g wheels and a guard or conductor adjacent thereto. Fig. 8 represents a right-side elevation of the filler forming, wrapping, pasting, and sealing mechanism on that side of the machine-next the operator. Fig. 9 represents a transverse section through the devices for regulating the tension upon the paper-Wrapper strip. Fig. l0 shows the cutting mechanism, partly in elevation and partly in vertical transverse section, on the line 10 10 of Fig. 2, looking toward the discharge end of the machine; Fig. 11, a plan view of the cutter-actuating IOO gears; and Fig. 12 a detail view in section of the central bearings of the carryingnarms, which support the cutter-disk and the discharge-tube.

Arrows indicate the direction in which the various parts of the machine move.

The salient features will first be described, successively, from the feed to the discharge end, then the actuating mechanism, and li n ally the operation.

The mechanism is shown as mounted on a main frame A, from the front end of Which extends a feed-supporting frame AQ over which traverses a feed-apron B, which terminates near a carding-cylinder or feed-roller C, rotating within a casing C. A cylindrical brush or feedroller D, rotating in contact with the teeth of Ithe carding-cylinder and at a higher rate of speed, discharges the tobacco into a hopper E. These parts just described resemble those shown in my patent above mentioned.

The tobacco falls through the open bottom of the hopper upon the periphery of the main carrying-wheel F, provided with a vertical flange f on the left-hand side of its periphery and with a peripheral semicircular groove f at or near the junction of the flange with the rim of the wheel. A second carrying-Wheel or ring G carries upon its inner or left-hand peripheral edge a vertical iiange g. The pcriphery or rim of this last-mentioned Wheel projects on one side in such manner as to overlap or encircle the periphery of the main carrying-wheel F, the two Wheels being concentric and revolving concentrically on coincident axes. Their speed of rotation is made uniform by forming slots or recesses f2 in the Wheel F, which interlock with the spokes g of the Wheel or ring G. The Wheels are fur ther locked together by means of lugs or studs f3, projecting from the wheel F, and Which abut against the spokes of the ring or Wheel G. The interlocking devices are detachable or separable and come into play only on the converging side of ythe Wheels, being disconncctcd by the divergence of the Wheels at the feed end, this connection and disconnection being constantly repeated during the rotation of the Wheels, by which means the ring or wheel G is driven from the Wheel F and their uniform rotation is secured. The axes of the flanged Wheel F and the flanged ring or Wheel G are arranged in the same horizontal plane, but at a slight angle to ea-ch other, so that the recess or trough formed by their flanges tapers from the feed to the discharge side.

The shaft F of the Wheel F is mounted in fixed bearings in the frame, its inner end being rounded at f4, as shown in Fig. 3, and interlocking with the correspondingly-recessed end of the shaft G of the Wheel or ring G. The opposite end of the shaft G is connected by a ball-and-socket joint g2 with a screwshaft g3, supported in a bracket g4 on the main frame, by which means the Wheel G can be adjusted relatively to the Wheel F.

A compressing-Wheel H, provided with a semicircular peripheral edge h and mounted in suitable bearings on the frame, runs bctween the flanges j' g of the main carrying- Wheel F and flanged ring or Wheel G, at or near their point of closest approximation, on their discharge side. The tobacco is compressed into a cylindrical or rod-like form by means of the corresponding grooves in the carrying-Wheel F and compressing vhcel Il.

The front end of a guard-plate I abuts against the flanges f and g of the ii1ler-carrying Wheels F and G, as shown in Fig. 7, While its protruding tongue 'L' passes between said flanges and into the annular groove f', thus serving to prevent the escape of any loose fibers of tobacco at that point. This guard encircles the lower part of the compressing- Wheel H and extends to the point Where the carrying-belt J and overlying paper-wrapper strip 7a, carried thereby, pass over a small roller 7' to the Wrappin g devices, thus serving as a guide or conductor to deliver the formed filler upon the paper-Wrapper strip.

An endless belt J passes around a large ley J 2, through an adjustable guide J 5, around a small rollerj, and through the Wrappin g devices. The roller j is mounted in a bracket j', adjustable by means of a slot and set-screw f2, so as to regulate the tension of the belt.

The paper-roll is mounted on a shaft K, and upon its periphery bears the lower or outer end of a plate-spring K', which carries guide-pins 7c on each side of the paper-roll to maintain the spring in proper position. The upper or inner end of the plate-spring K is secured to asleeve 7a2, turning on a fixed stud-axle K2. A spiral spring 7a3 is secured at one end to a sleeve 7a, while the other end bears against the plate-spring K. The tension of the spring is regulated by turning the sleeve 755 upon the fixed stud-axle K2 and locking it in position by a set-screw k". The pressure of the plate-spring is thus regulated by the tension on the spiral spring. The strip of paper 7e traverses the plate-spring, Which acts as a guide therefor, While also acting as a pressure device upon the roll of paper.

A doctor or scraper l, mounted on a supportingframe L, projects into the groove of the compressing-Wheel H to clear it of any adhering tobacco. Yielding guide-rods l', mounted on the frame L, on opposite sides of the roll H, bear upon the paper strip near its opposite edges as it enters the wrapper-guide M and retain it in proper position.

Any preferred form of folding, Wrapping, and pasting devices may be employeds uch, for instance, as those which are shown in my Letters PatentNo. 512,151, above mentioned. The construction and operation of these parts being Well understood need not be described in detail.

'The completed cigarette is delivered by the belt into a Haring-mouthed discharge-tube O,

IOO

IIO

carried by a sleeve o, vertically adjustable upon an arm O', rocking centrally in swivelbearings o' on the frame. The lower end of this rocking arm is connected eccentrically by a ball-and-socket joint with a spur-gear O2, which meshes with a corresponding gear P2, driven by another spur-gear Q. This lastnamed spur-gear is connected with an upright shaft Q', the lower end of which turns in a fork q on the same supporting-bracket that carries the gears P2 and O2. This arrangement permits the shaft Q' to be adjusted nearer to or farther from the gear P2, so as to admit of the use of a gear of larger or smaller size than the gear Q to vary the speed of the cutters.

The cutting-disk P is carried by a sleeve p, adjustable vertically upon an arm P', rocking upon a pivot p', and eccentrically connected at its lower end to the spur-gear `P2 above mentioned.

The bearings o' and 1o' (shown particularly in Fig. 12) are adjustable to vary the throw of the arms O' and P'. The frame A, it will be observed, is slotted at c., and the trunnions a' of the bearings o' and p' lit into concentric sleeves, which are provided with the clampcollars a2 a3, that may be tightened and loosened to permit of the adjustment of the bearings in the frame, while the bearings are adjustable on the rods O' and P' by means of the set-screws a4, as indicated in Figs. 10 and 12. It will thus be seen that the deliverytube and cutting-disk are similarly actuated, so as to cause both the cutter and the completed cigarette, as it passes through the delivery-tube, to vibrate laterally relatively to the normal line of movement of the cigarette, and thus insure a very quick action with the minimum of lateral movement. It will likewise be observed that both the cutter and delivery-tube are caused to move simultaneously and quickly with the continuous cigarette while severing it, and that an even cut is insured.

The cutting devices may be covered, if desired, by a table R, mounted on suitable supports, to protect the operator and afford areceptacle for tools. A driving-belt S encircles the pulley S', which is connected by a suitable clutch and lever S2 with a horizontal longitudinal driving-shaft S3, mounted in suitable bearings in the main frame.

The carding-cylinder C and brush D are driven from the driving-shaft by a belt T, and the flanged filler-carrying wheels F and G are driven from the driving-shaft by a worm u, meshing with a worm-gear U on the shaft F'. The wheels F and G are preferably of large diameter, (the larger one being, say, thirty-six inches in diameter,) so that they may be driven at a comparatively slow speed and yet have a rapid peripheral movement.

The grooved compressing-wheel I-I is driven by friction from the wheels F and G, the flanges of the latter being in contact with the wheel H, as shown in Figs. 4 and 6. The

drivin g-wheel J is driven by a worm r on the drivin g-shaft, which meshes with a worm-gear V on the shaft of the wheel J'. Aworm-gear w, secured to an upright shaft W, is actuated by a worm w on the' driving-shaft and operates mechanism which supplies paste to the ter-shaft.

In voperation fibrous tobacco, in a loose shredded condition, is fed by hand upon the apron B and carried to the carding-cylinder C, which draws out the fibers which are released therefrom bythe more rapidly-revolving brush D and discharged through the open bottom of the hopper E onto the periphery of the main carrying-wheel F and between its flange fand the corresponding iiange g ofthe concentric carrying-wheel or ring G. The gradual approximation of the converging flanges f and g compresses the tobacco laterally, as the wheels rotate, into the annular semicircular groove f' and under the grooved compressing-wheel H, which compresses it into a cylindrical rod and discharges it over the guide I upon the paper-wrapper strip 7c, which moves lengthwise over the tension sprin g-plate K'. The belt J carries the wrapper and ller through the folding and wrapping devices, duringits passage through which paste is applied to one edge of the paper strip by the paste-wheel N, the pasted edge of the paper being folded down upon the other edge and sealed so as to envelop the filler and form a continuous cigarette. The belt then flattens out in passing over the large wheel J and the continuous cigarette passes through the longitudinally-movable delivery-tube, which also vibrates laterally across the normal line of travel of the continuous cigarette. The cutter-disk likewise has a similar longitudinal and also a lateral movement, as before described, to sever the cigarette-rod at suitable intervals into cigarettes of smokable lengths.
