SPECIFICATION forming part of Letters Patent No. 594,375, dated November 30, 1897.

Application filed January '7 1 S9 '7.

r To all whom it may concern.-

Beit known that we,JAMES A. BONSAOK and l-Iuco BILGRAM, citizens of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Cigarette Machinery, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

The present invention relates generally to mechanism for forming tobacco fillers for cigarettes, in which the tobacco in regulated or measured quantity is fed or showered upon a receiving-surface, which is divided into equal compartments, in such manner that each compartment shall receive the desired quantity or parcel of tobacco for a cigarette-filler. The parcels of tobacco thus formed are successively discharged from the receiving-compartments and are delivered to mechanism by which they are compressed into the proper form of cigarette fillers, this compressing mechanism being driven or operated in unison with the mechanism by which the parcels are delivered thereto, whereby the movements of each of these mechanisms are so related to each other that each parcel of tobacco will be d'elivered at the proper time to be acted upon by the compressing mechanism; and the invention consists in the various novel features of construction and combina tion of parts, which will be more particularly described in the following specification and pointed out in the claims.

For a full understanding of the invention a detailed description of a machine of the preferred form embodying the same will now be given in connection with the accompanying drawings, formingapart of this specification, in which- Figure 1 is a front elevation of a part of a cigarette-machine embodying our'invention, certain parts being shown in section.

Fig. 6 is an enlarged end View of the parcel-discharging mechanism, certain parts being broken away and others shown in section. Fig. 7 is a vertical section along line 7 7 of Fig. 6 to show the construction and operation of the parcel-discharging mechanism, certain parts being omitted and certain parts being shown in dotted lines on either side of the section-lines. Fig. 8 is a side elevation as seen from the left hand of Fig. -6. Figs. 9 and 10 are detail views of the compartmentapron. Fig. 11 is a sectional View of a modification of certain parts of the mechanism shown in Fig. 4 for delivering the tobacco to the compartment-apron, the section being taken along the same line as in Fig. 4.- Fig. 12 is a View of a conical or tapered cigarettefiller, and Fig. 13 is a view of a cigarettefiller ofuniform diameter throughout its length.

Referring to the drawings, A is a hopper supported upon the frame of the machine and forming the upper part thereof and adapted to receive tobacco to be operated upon to form cigarette-fillers.

B and O are cylinders or rolls constructed and arranged to rotate in the hopper, the cylinder B being designated the feed-cylinder and the cylinder 0 the filling-cylinder. These cylinders are" arranged so that their adjoining surfaces will be quite near each other, and they rotate upon their axes in the same direction, which causes their contiguous surfaces to move in opposite directions. The surface of the f eed-eylinder Bis provided with rows of teeth, which preferably incline in the direction of the rotation of the cylinder,which is indicated by the arrow on Fig. 4. The surface of the filling-cylinder C is also preferably provided with short teeth or other roughened surface, the teeth being inclined in a direction opposite to the rotation of the cylinder. The feed-cylinder B is connected with the driving mechanism, so as to rotate continuously, but the filling-cylinder is arranged to rotate intermittently, preferably having a peripheral speed, when moving, greater than that of the feed-cylinder, for the purpose hereinafter set forth. There is also shown in the drawings a brush-roll D, arranged to operate in connection with the cylinder 0 to remove therefrom any particles or fibers of tobacco which may be retained thereon. A stripperroll E, provided with teeth arranged to operate between the teeth of the feed-cylinder, is arranged to rotate in connection therewith. The location and relative arrangement of these cylinders or rolls is clearly shown in Fig. 4, in which the cylinder 13 occupies the bottom part of the hopper, the lower part of its periphery being in close proximity to the wall of the hopper and its upper part being in position to receive and support the mass of tobacco as it is placed in the hopper. The filling-cylind er O is arranged above and somewhat in front of the cylinder B and preferably in such relation thereto that the teeth of theircontiguous surfaces are nearly in contact. The brush-roll D is preferably located near the upper surface of cylinder C, and the stripper-roll E is located in front of the cylinder 13. Above the stripper-roll is preferably located a presser of comb-like construction, secured to the end walls of the hopper and provided with teeth arranged to act between the rows of teeth of the feed-cylinder and press upon the tobacco and prevent its uneven removal by the stripper-roll.

As shown in the drawings, the moving parts above described are connected to the prime motor and are driven as follows:

ais the main shaft, driven from pulley I), and the brush-roll D is secured to rotate with this shaft, while on its opposite end the pulley c is connected by the cross-belt (Z to pulleye on the shaft of the stripper-roll E, the pulley f on the opposite end of this shaft being c011- neeted by belt g to fast and loose pulley 7L on shaft t'.

The feed-cylinder l3 and the filling-cylirr der C are driven from the shaft t through a feed-regulating device, the construction and connection of these parts being as follows: The shaft 2' carries a cone-pulley j, which is preferably connected by the cross-belt 7a to a second cone-pulley Z, fixed to a movable suspended shaft m, carrying a pinion n, the shaft m turning in the sleeves 0 on the free ends of arms 1), fixed to rock-shaft q, the latter being journaled in the frame of the machine. The shaft m is made laterally movable to give and maintain the desired tension on belt k to drive the cone-pulley Z, and its movement is controlled by spring 0', attached at one of its ends to bar 3, while its other end is secured to arm t, which in turn is fixed to shaft q, the latter carrying gear-wheel u and pinion 1;, said pinion engaging and driving gear-wheel w on shaft :6, journaled in the frame of the machine, which shaft 00 carries a sprocket-wheel y, connected to sprocketwheel a arranged to rotate 011 stud 11 by a chain belt 0 Mounted on an eccentric on the hub of sprocket-wheel a is a pawl d so arranged in relation to ratchet-wheel e fixed to shaft f which carries the filling-cylinder C, that each rotation of the sprocket-wheel a will give the free end of the pawl d which engages the successive teeth of the ratchet-wheel, a forward thrust to intermittently rotate the. cylinder 0, a retaining-pawl 9 being provided to prevent reverse rotation. The feeding-cylinder B is driven from a pinion 7L2, also mounted on the hub of the sprocket-wheel a and said pinion meshes with and drives gear-wheel 1L mounted on stud k carrying pinionj which latter drives gear-wheel Z fixed to shaft 011?, on which the cylinder B is mounted. It is observed that the driving connections of the cylinders B and O with the hub of sprocket-wheel a are such that the cylinder 0 is rotated intermittently, while the cylinder B is rotated continuously; also, that the speed of the surface of cylinder 0 when it is in motion is preferably somewhat greater than that of the cylinder B, which two conditions of operation are considered desirable.

The belt 7a, which connects the cone-pulleys j and l, is moved along the surface of said pulleys in order to increase or decrease the speed of shaft on and the speed of the rotation of the cylinders B and 0 through their connections with the shaft m by means of any device adapted for this purpose, as a screwthreaded nut or, carrying arms 0 arranged to push or pull against the belt, the said nut being moved bya screw-threaded shaft 12 as shown in Figs. 1 and 4:.

The function of the devices thus far described is to measure from the tobacco in the hopper certain definite and determined quantities and to dispose of it in a uniform web or sheet on the surface of cylinder 13 and between the teeth thereof and to uniformly remove it therefrom and shower or deliver it upon a receiving-surface, for the purposes hereinafter more fully described, and the operation of these devices is, briefly, as follows:

Fibrous tobacco adapted forcigarettes, generally in an irregular, undistributed, or unarranged mass, is placed in the hopper, which by its shape causes it to rest upon the upper surface of feed-cylinder l3, and as this cylinder rotates its teeth draw or comb a surplus of tobacco from the mass and carry it to the filling-cylinder and into the bite of the feeding and filling cylinders. The filling-cylinder during each of its short periods of rest from rotation forms a stationary guide which operates to press or force the fibrous tobacco down between the teeth of the feed-cylinder as the tobacco is carried forward by the continuous rotation of the latter cylinder, so as to more fully and uniformly fill the teeth than would be done were the rotation of the filling-cylinder continuous, while any undesired quantity or surplus of tobacco which has been carried forward between the cylinders is swept or forced backward toward the main mass by the quick short rotation of the filling-cylinder. The periods of rest and movement of the filling-cylinder are of very brief duration, but are sufilcient, on the one hand, to enable the teeth of the feed-cylinder to become fullyfilled and, on the other hand, to prevent too much surplus tobacco from passing the bite of the cylinders and the web or sheet of tobacco from being too much condensed. The result of this operation is to form the tobacco into a web or sheet of substantially uniform consistency and thickness on the surface of the feed-cylinder, the thickness of the web being substantially equal to the projection of the teeth of the cylinder and its width equal to. the length thereof. After the web of tobacco has been thus formed it is advanced by the rotation of the feed-cylinder underneath the compressor-comb B and thence to the stripper-roll E, whose teeth int-ermesh with those of the cylinder B and, coacting with the compressor-teeth, uniformly remove the tobacco therefrom and shower it down in a light fibrous condition suitable for cigarette-fillers.

It is observed that as the speed of the feedcylinder and the stripper-roll E are continuous and the tobacco is continuously presented to the stripper-roll in a web of substantially uniform thickness and consistency the stripper-roll operates to remove from the feed-cylinder and shower down uniform quantities of tobacco. It is also observed that the cylinder B furnishes a continuously-traveling surface provid ed' with proj ectin g teeth, which can be filled with tobacco to form a web or sheet of substantially uniform thickness and density, and that the cylinder 0 provides an intermittently-traveling surface so arranged relatively to and cooperating with the surface of cylinder B as to fully and uniformly fill the teeth of the latter with the desired quantity of tobacco, while the stripper-roll E operates to remove the web of tobacco from between the teeth of the traveling surface B and uniformly shower it upon any'receiving-surface placed beneath it. It is not essential that these traveling surfaces be cylindrical, but they may be of any suitable shape, provided they cooperate to produce the abovedescribed results.

WVe will now describe the preferred form, as shown in the drawings, of the mechanism or devices by which the tobacco as it is uniformly removed from the stripper-roll is received and divided into parcels upon a receiving-surface in the desired quantity and shape for cigarette-fillers and the devices or mechanism by which such parcels are discharged or removed from the receiving-surface and delivered to mechanism by which they are compressed to their final shape and thus prepared to be associated with wrappers to form completed cigarettes.

Beneath the stripper-roll E lies an endless apron or belt G, preferably running parallel with the axis of the roll E and passing over drums H H, journaled in attachments A A, properly secured to the opposite ends of a piece I, which is fixed to the main frame of the machine. This apron is divided into a number of equal compartments by transverse partitions J, in length substantially equal to or slightly lon ger than the length of the fillers desired and centrally secured to the body of the apron in any desired manner, but preferably, as shown in detail in Figs. 9 and 10, by screws r countersunkin cleats s on the under side of the apron, which pass through the apron and are then screwed into the partitions J. The apron may be of leather or any suitable flexible material, and the partitions and cleats may also be of any suitable material, as wood, brass, aluminium, or other metal. This compartment-apron is arranged to run between side guides a a and b 19 which operate to prevent the tobacco from falling out of the ends of the compartments, while the free and unobstructed edges of the apron preferably run in narrow grooves 0 0 as seen in Fig. at. The shape of the partitions J is preferably substantially that shown in cross-section in Fig. 10, in which the bases of the partitions are sufficiently broad to receive the clampingscrews r while their sides converge to form thin edges, as T so that only very limited surfaces will be presented for the lodgment of fibers or particles of tobacco. A small brushroll, as R conveniently fixed in the walls A as shown in dotted lines in Fig. 7, may be employed to remove any fibers of tobacco which may be retained upon the edges r and deposit them in the compartments. If desired, this roll may be arranged to revolve by any suitable connection to the driving mechanism.

Inasmuch as the discharge of the parcels of tobacco from their compartments and their delivery to mechanism for compressing them tofiller form is dependent upon the movement of the compartment-apron it is important that the apron be driven in exact unison with the compressing devices, and especially that no slip of the apron on its drums be permitted. For this purpose the drums H and H are provided with longitudinal grooves K to receive the cleats 5 which construction will operate substantially like a sprocket-wheel and chain belt, as seen in Figs. 1 and 7, and will make the advance of the apron positive and exact.

In order to give the desired form to the parcels of tobacco in the apron-compartments, a deflecting-surface L is arranged above the partitions J of the apron G, the lower edge of such surface or plate running in a diagonal directionrelatively to the width of the apron or the length of the compartments. This defiecting surface or plate is conveniently secured to the guide a which latteris preferably made removable for the purpose of applying other deflecting plates of different form and direction, and extends from one end of the stripper-roll E toward but preferably not entirely to the opposite end thereof, thereby gradually exposing more of the width of the apron in the direction of its movement, as seen in plan in Fig. 2.

As the tobacco is showered down by the stripper-roll it is deposited in the compartments as they are advanced beneath the roll, the arrangement being such that several of the compartments receive the shower of to-. bacco simultaneously; but the tobacco is not distributed uniformly throughout the length of the compartments, since as it is showered down a part of the tobacco falls directly upon the exposed portion of the apron, while a part falls or is thrown upon the inclined deflectingsurface L and slides down such surface and falls from the edge thereof upon that portion of the apron or bottom of the compartments which is directly beneath such edge. As the lower edge of the deflecting-surface runs diagonally across the compartments, it results that when a series of compartments are advanced beneath the stripper-roll the tobacco will be deposited in larger quantity in the ends of the compartments which are not covered by the diagonal deflecting-surface until the compartments pass the end of such surface, when the tobacco may be deposited along the entire length of the compartments. This construction and operation will give parcels of tobacco of substantially equal quantity in each compartment; but the parcels will be larger at one of their ends and will gradually decrease in size or quantity of tobacco toward their other ends,thereby adapting them,when properly compressed,to form fillers for conical or tapered cigarettes, as shown in Fig. 12, for which this machine is more especially designed.

A modification of the construction above de-. scribed is shown in Fig. 11 of the drawings, in which a concave guide M is located beneath the stripper-roll E to cause substantially all the tobacco as it is removed from the feedcylinder B to be carried out laterally by the stripper-teeth and thrown against the inclined deflecting-surface L instead of being showered directly down from the stripper-roll, so that a part of the tobacco will fall upon the exposed part of the apron G and a part upon the deflecting-surface L, as in the construction shown in Figs. 2 and 4:, where the concave is omitted. In the modified construction substantially all the tobacco is thrown against the deflecting-surface L throughout its whole length, and as it falls or slides down such sur face and drops from the edge thereofit is deposited in the compartments and upon the apron forming the bottom thereof in parcels which contain an equal or uniform quantity of tobacco throughout their length and are thereby adapted, when properly compressed, to form cigarette-fillers of uniform diameter, such as are shown in Fig. 13.

To understand more clearly the operation of the modified construction whereby the tobacco is deposited in the compartments in parcels containing equal and uniform quantities of tobacco throughout their length, it is simply necessary to consider that the concave M operates to cause substantially all of the tobacco to be thrown against the deflectingsurface L and that it is deposited in the com, partments only as it slides down such surface and drops from its edge, which edge runs diagonally above the compartments. As the compartments are advanced under and along the length of the deflecting-surface L the tobacco, as it drops from the edge of this surface, will be deposited in suchpart of the length of the compartments as is immediately under such edge, and for any one compartment this part will vary with the advance of the compartment by reason of the diagonal direction of the edge. So, also, as substam tially equal quantities of tobacco drop from this edge in equal times, and as the advance of the compartments is uniform, it results that when any compartment has passed the entire length of the deflecting-surface L the tobacco will be deposited in a layer or parcel of substantially equal thickness throughout the length of the compartment and will be in condition when properly compressed to form a cigarette-filler of uniform diameter throughout its length.

It is desirable for the purpose of maintain? ing the shape of the parcels of tobacco, as well as to conform to the desired movements of the filler-compressing mechanism, to discharge each parcel from its compartment and deliver it in a single mass rather than in a shower or in driblets, and for this reason it is preferred that the discharging devices be intermittent in their operation. It is also desired that no incomplete parcels, such as may be deposited in the compartments in starting or stopping the machine, be delivered to the compressing mechanism, and devices are shown in Figs. 1, 6, 7, and 8 for accomplishing these results. In these figures, N is as pout or chute located below the drum H and leading from the com.- partment-apron to the compressing mechanism, the mouth or upper opening of this spout being alternately closed and opened to each compartment by any suitable devices, as a swinging door operated by suitable mechanism. As shown in the drawings, the door 0 is fixed to a shaft P, journaled in the attachment A and is operated by a rotating cam R through an arm S, fixed to shaft P and held in position by spring T, attached to locking-arm U, located at the opposite end of the shaft P, as seen in Fig. 8, the cam B being fixed to sleeve V, arranged to rotate on stud V, as hereinafter more fully described.

The door 0 is curved, so that when in its closed position the edges of the partitions J will sweep over its interior surface and in such proximity thereto as to remove the parcels of tobacco therefrom. Between the free end of the door 0 or side of the spout N and the lower edge of any one of the partitions J which has passed this point, as seen in Fig. '7, is an opening X, through which the parcels can be successively raked out by the moving partitions and discharged in case they are incomplete or for any reason it is impracticable to deliver them to the compressing and shown in the drawings, as these can be varied without affecting the principle of its construction and operation; nor do we wish to limit our invention to the special construction and operation of the series of compartments for receiving the parcels of tobacco for cigarette-fillers, or to the special means for depositing the proper quantity of tobacco in such compartments, or for discharging the same therefrom, or to the special means for connecting the discharging mechanism with the compressing mechanism shown in the drawings, as all these constructions can be varied without departing from the principle of the invention.
