CIGARBUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 406,329, dated July 2, 1.889.v Application filed July 13, 1887. Serial No. 244,211. (No model.)

To @ZZ whom it may concern-.-

Be it known that I, JOHN H. ABRAHAM, a citizen of the United States, residing at Lancaster, in the county ot Lancaster and State of Pennsylvania, have invented certain Improvements in Cigar-Bunching. Machines, of which the following is a speciiication.

This invention relates to improvements in machines for bunching and rolling the' fillers of cigars in their binders; and the objects of the improvements are, first, to feed the fillers in given quantities into the receptacle in which they are wrapped in their binders in such .manner as to avoid the friction and strain produced by machineryT in which the surfaces of the parts slide upon veach other; second, to automatically produce a pocket in the forming-apron for the reception ot each bunch of fillers as it is delivered from the hopper, and, third, to automatically open and close the wicket of the chtite by which the lilling material is conveyed from the hopper at the proper time to deliver each bunch of iillers into the pocket formed for its reception. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a machine embodying my invention,partiallyin section, showing the pocket formed and the wicket open. Fig. 2 is a similar view showing the treadle depressed and the operating parts in a different position, showing the cylinder in position to deliver the bound filler and with the wicket closed; Fig. 3, a front view ot" the machine with part of the frame A, shell of the roller M, and front of the hopper B cut away to afford a view of the operating parts. Fig. et is a rear elevation of the buncher with part of the frame and rotating cylinder cut away to show the spring 15'; Fig. 5, a top or plan view showing the arrangement `and mode of operatimg` the feed-screw and agitating-arms. Figs. 6 and? show end and front views of a modification in the rotating cylinder and the spring-roller whereby the pocket is formed. Figs. 8 and 9 are similar views of another modication, the parts being partially cut away in the side view. Figs. 10 and ll show an enlarged end and top view, the former partially in section on line x, of the rotating cylinder, forming-apron, and rollers, with the belt drawn down to form a pocket and the binder andtobacco 4 in place as seen just before the rolling process begins; Figs. l2 55 and 13, similar views of the same with the tobacco et in the position it occupies while the rolling mechanism is in operation; Figs. 14 and l5, views of the same showing the cigar 4 after the rolling has been completed. Fig. 6o

1G shows an end view ot rolling device after the rolling is completed.

Similar letters indicate like parts throughfout the several views.

In the drawings, A represents-the supporting-frame; B, the hopper, and C a feed-screw extending through said hopperl from back to front, and having bearings in the rear plate b of the same, and supported by the arms b in front. horizontal plates b2 b3, forming the double bottom of the hopper, and carries the filling material received on it from the opening b in the upper plate b2 to the opening d in the front plate, whence it is delivered into the chute D.

Motion is given to the screw by means of a strap or chain E, attached to the treadle at e. This strap passes up from the treadle over the roller d, mounted on the rod a', eXtend- 8o narily be used; and the depression of the 9o treadle through the strap E and the collar F, with the pawl f engaging the ratchet f', imparts such motion. Inside of the collar F there is a coiled spring e which acts to throw the collar back and take up the slack in the 95 strap as soon as the treadle is raised.

IThe size of the opening b4 in the plate b2 is regulated by means of a slide d', resting on the said plate in front of the opening, and is rendered adjustable by means of screw-'roo The screw is located between the 7o The collar has a pawl f atthreaded pins c, projecting through slots c in the sides of the hopper, and provided with set-n uts c2.

G G are two agitating-shafts extending longitudinally through the hopper, and having radially-projecting agitating arms or spurs g, which rake the tobacco filler toward and into the opening h and upon the feedscrew. The shafts G G are rotated by means of the coggearing at the rear of the hopper. In this gearing', c3 represents a driving-wheel fastened rigidly to the spindle of the screw, which meshes with the cog-wheel g on the shaft G', that engages in turn the cog-wheel g2 of the shaft G. The drivi 11g-wheel sets out from the end of thehopper, and the cog-wheel g' is of considerably greater thickness than the driver, so that it engages eog-wheel g, located back of the driver, and causes it to move in the opposite direction. The feed-screw projects su flicien tly far beyond the front plate of the hopper to carry the tobacco iiller to the outside thereof, where it is received by the chute D. A wicket 7L is hinged near its upper edge to the chute, and is opened at the proper time to deliver its load by the leverI.

.I represents the rotating cylinder in common use with bunching-machines of this class, and K the forming-apron, or apron surrounding the same. Zt' is a recess extending across the cylinder to receive the slack portion of the apron drawn down into it to form a pocket when itis under the chute to receive the charge therefrom, the amount being sufficient forl the filler of one cigar. As the cylinder is rotated forward the filler is wrapped in its binder and revolved in the apron between the cylinder and two rollers Z Z, placed one above the other immediately in front ot' said cylinder and close enough to it to prevent the cigar being rolled from passing around with the apron.

Immediately in front of the recess Zt' there is another similar recess 7.3 in the cylinder, in which the ends of the apron are secured. lVhen the latter recess is brought opposite the rollers Z Z the bound filler is discharged into it, and after being taken therefrom the cylinder is permitted to be revolved backward until it resumes its origin al position. The forward movement of the cylinder is produced by a strap t, connecting it with the treadle T and wound about and secured to one end of the cylinder inside of the bearing. rl`he reverse movement is produced by a spring t', coiled about the opposite end of the cylinder. This spring has only to lift the slack of the strap Z, as the treadle itself is raised by a powerful coiled spring S, connecting said treadle with the part of the frame above it.

M represents a roller journaled below the rollers Z Z, in which there is a strong coiled spring' m, adapted to hold the said roller in position. To this roller there are attached cords m', which are wound about it. One of these cords is placed on each side of the roller under the edge of the forming-apron, and

each has one end attached to the edge of the apron. This roller is so located and the cords are attached to the apron at such points as to draw the slack of the apron down into therecess Zt' and form a pocket therein when the said recess is .under the chute. Then the cylinder is revolved forward by the depression of the treadle, the apron is carried with it, and the cords m', which also pass about the rollers Z Z, follow, revolving the roller M and tightening the spring therein, so that when the cylinder is rotated backward and the recess k brought again beneath the chute the apron, by means of the spring m and the cords m', is automatically retracted into the said recess to form a pocket.

To keep the slack of the apron in position under th e chute when the cylinder is retracted, and thus facilitate the formation of the pocket, I have a roller N journaled in the frame above the cylinder and in such close proximity to it as to hold the slack of the apron in front of it when said cylinder is revolved backward. This roller may be covered, if desirable, with a rubber or other jacket to prevent more et' the apron slipping backward between it and the cylinder than is necessary to follow the movement of the same.

Figs. G and 7 illustrate a modification of the method by which the apron K may be drawn down to form a pocket in the recess Zr.. In applying this method the roller h supplied with the retracting-spring, as in the construetion first described, is located inside of the cylinder J and journaled in the ends thereof. The retracting-cords m are wound about the roller and pass out of slots ai, cut in the eylinder entirely around it, and located adjoinin g that part which carries the apron K.

The connection between the treadle and the spindle of the screw and of the latter with the shafts of the agitatorsv is so arranged that each depression of such treadle may cause such revolution of the screw as to discharge sufficientA filling material into the chute to form one cigar and to have said agitators act during such revolution. The slide d regu* lates the amount of tobacco thrown down upon the screw through the opening in the plate b2, so that the said amount may be varied to suit the size of the cigar te be made.

The connections of the lever for opening the wicket of the chute, the belt-receiving recess in the cylinder, and the spring-roller and cords connecting the same with the belts are so constructed that as said recess reaches its position under the chute the pocket is formed, and immediately thereupon the wicket is opened and the tobacco filler just received therein from the feed-screw is discharged into the pocket.

The operation of my invention is as follows: The loose tobacco is placed in the hopper B, and when the treadle T is depressed the screw C is caused te revolve for the purpose of feed ing the tobacco through the side of the hop- IOO IIO

passes around suitable rollers, and is wrapped at its upper end around the collar F, secured to the end of the shaft of the screw C. At the same time that the screw is caused' to revolve for the purpose of feeding out the tobacco the two shafts G G', provided with arms or spurs g, are caused to revolve for thepurpose of stirring up the tobacco in the hopper and preventing` it from clogging. The loose tobacco is forced by the screw C into the chut-e D, which is provided with a wicket h. At the same time that the treadle T is depressed the strap r causes the cylinder J and pulley jx to revolve, which pulley is provided with a pin j for the purpose of engaging with the hooked rod h2, which operates the lever I, for the purpose of opening the wicket h at the proper time to deliver the tobacco in the pocket formed by the apron K when the cylinder is in the position shown in Fig. l.

The cylinder J is provided with recesses k 7;', which extend lengthwise with the cylinder.

In the recess 7c a pocket is formed by the slack of the belt being drawn down therein by means of the spring-actuated roller M, from which the cords extend for the purpose of catching hold of opposite edges of the belt and drawing the slack down into the recess to form the pocket to receive the tobacco from the chute D.

In connection with the cylinder J the rollers Z l are used, and around which the apron Klis made to pass, both ends of the belt being fastened to the cylinder in the recess k. Also used in connection with the cylinder is the roller N, which operates in connection with the apron K for the purpose of preventing the slack of the apron from moving past the recess lo. NVhen the treadle is released it is instantly returned to position by the spring S, connected thereto, and then the spring or springs connected io the cylinder instantly cause it to revolve into the position shown in Fig. l, so as to receive the filler in the usual manner. As soon as the cylinder is forced forward by its spring into the position shown in Fig. l the cords connected to the springactuated roller M draw the slack of the apron down into the recess r to form a pocket. Then the treadlc is depressed, the cylinder is rotated into the position shown in Fig. 2, so as to roll the filler.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

l. In a cigar-bunching machine, the combination, with the rotating cylinder having a recess formed in its side, a spring-actuated roller, cords extending therefrom, and the apron to which the cords are attached,whereby` the slack of the'apron is drawn down into the recess to form a pocket, substantially as set forth.

2. The combination, in a cigar-launching machine, of the apron, the cylinder or surface upon which the apron is placed, and which is provided with 'a recess, a springactuated roller, and guiding-rollers for the belt and cords, which are attached to opposite edges'of the apron, so as to draw its slack down into the recess to form a pocket, substantially as shown.

3. In a cigar-bunching machine, the combination of the hopper and the chute having a wicket with the rotating cylinder having a recess formed in its side, the apron, and a spring-actuated roller, cords extending from the roller and connected to opposite edges of the apron, whereby the slack of t-he apron is drawn down into the recess to form a pocket, substantially as described.

4. In a cigar-bunching machine, the combii nation, with the surface on which the bunch is rolled, said surface having a recess formed therein, of the apron and the cords fastened to said apron, and having a spring attachment whereby the apron is drawn down into the recess to form a pocket. p

5. In a cigar-bunching machine,the combination, with the surface upon which the bnn ch is rolled, and which is provided with a recess which extends across its surface, of the apron and a spring attachment whereby the apron is drawn down into the recess to form a pocket, substantially as shown.
