CIGAR-CORE-WRAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 651,147, dated June 5, 1900.

Application filed May'lS, 1898. Serial No. 681,025- (No model.)

To all whom it may concern:

Be it known that I, J OHANN RUDOLF SOHMITT, a subject of the King of Prussia, Emperor of Germany, residing at Oberrad, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Cigar-Gore-Wrapping Machines, (for which I have applied for a patent in England, dated March 24, 1898, No. 7,137,) of which the following is a specification.

The object of this invention is a cigar-corewrapping machine by means of which cigarbunches'of various shapes can be made very quickly and with perfect uniformity of size and density or tightness.

The machine is shown, by way of example only, in the accompanying drawings, where- 1n Figure 1 is a side view of the machine. Fig. 2 is a detail view of the feed device. Fig. 3 is a detail view of the stopping device for the feed device, showing the inactive position of the stopping device in dotted lines. Fig. 4 shows a detail view of an appliance whichprevents the tobacco from separating when being cut, and Fig. 5 is a side view of the same. Fig. 6 is a front View of the driving mechanism mounted on the two main shafts. Figs.

7 and 8 show the driving-gear for the traveling band. Figs. 9 and 10 show a rolling appliance for straight and conical enwrappings,

respectively.

The tobacco is fed by the traveling band a, Fig. 1, and shot in suitable lengths into the former or mold e, which has a size and form corresponding to one of the cigar shapes provided for, wherein the said tobacco is pressed by the ram 9 and whence it is subsequently fed by the slide It, connected to the lever 70 out of the mold e onto the band h. To be able to feed the tobacco in a compact form on the band 72, rails Zare provided above the said band h and can be fitted accurately against the mold (2, so as to hold the tobacco throughout the length of its travel into a proper form. After the tobacco has been fed up to the knife m by the band It the tobacco mass which has to be made into a filler and enwrapped is detached and driven by the ramrod 12 onto the enwrapping mechanism.

The whole machine consists accordingly of the following parts: First, feed mechanism with stopping device; second, continuous feed mechanism; third,a pressing device when cut ting oif the tobacco; fourth, mechanism to facilitate the expulsion of the tobacco after the cutting-off operation out of the pressing appliance which held it tightly; fifth, enwrapping or coiling mechanism.

Feed mechanism with stopping device-The tobacco is placed on the traveling band a, Figs. 1 and 2, which feeds the same in separate predetermined quantities or bulk into the mold e. The said band a runs over two rollers b, one of which is suspended to a set of levers b, 19 12 ,12 and 19 Motion is imparted to these levers by the shaft B, which is set in rotation by the tooth-gearing c c, Fig. 1, actuated by the main shaft A. The shaft carries a cam b Figs. 1, 2, and 6, which actuates the lever b and thus imparts an intermittent motion to the traveling band a. The ratio of transmission from c to c is one to four, and hence the band a moves four times while the band It moves only once, in consequence whereof the tobacco is fed at intervals to the mold 6, so thatit can be better rammed into the mold e. 'After the tobacco has left the traveling band a it arrives upon a guiding-piece cl and is conveyed thence to the mold e by a second traveling band ct. The traveling band a is set in motion by one of the rollers b, which likewise, by the aid of a connecting-rod b and of a pawl-and-ratchet gear, imparts motion to a third roller 19 above, so that the whole feed mechanism is really driven by the lever b and the camb. 111 case the tobacco should not drop uniformly from the guiding-piece 61 into the former or mold this defect can be readily remedied by the aid of the knife f, Fig. l, which passes close against the front side of this guiding-piece'or inclined plane'd. The knifefis fixed to alever f which is arranged to turn on a pivot or fulcrum secured to the framework. The up-and-down motion is caused by the shaft B, with the aid of the crank f and the connecting-rod f The mass of tobacco in the mold or former is subjected to the action of a ramrod g, having a striking-surface corresponding to one of the cigar shapes selected and serving to properly arrange the tobacco in the said mold or former. The slide 7c subsequen tly knocks the tobacco out of the mold onto the second traveling band 71 The rama the tobacco fart-her on.

rod g is secured to a bell-crank lever g, f ulcrumed to the framework and actuated by means of the connecting-rods g and g by the cam g", mounted on the shaft B. This cam g has on a portion of its periphery a sharp notch or recess, as can be more clearly seen in Fig. (i, so that at each rotation of the shaft B, and hence of the cam mounted thereon in the direction indicated by the arrow in the said figure, the ramrod or pestle is allowed a sharp drop into the mold or former.

To prevent during the feed of the tobacco the traveling bands ct a from delivering too great a quantity of tobacco in the former or mold e and onto the traveling band 71,, a de Vice is provided for the purpose of stopping the feed mechanism in time. This device is shown in Fig. in a released or inactive attitude in full lincs,while the position of the same when the traveling band is at a standstill is shown in dotted lines. As soon as the space between the band 71, and the adjusting-bar i is oversupplied the lever 75 which is brought back into its normal position by a counterweight, being unable to accomplish its full motion or trajectory, causes the lever i connected to the lever 7.: by the connecting-rod t, to fall out of contact of the lever L, which becomes accordingly free. In consequence thereof the lever i is arrested at 1 and the tobacco cannot be fed forward any longer, as the shaft U is hemmed in by the lever b". This shaft 12 is, as shown, the driving-shaft for the two traveling bands (6 and a and is set in motion by the lever Z2 and the camb. The lever b is broughtback into its original position by the counterweight. As soon as the tobacco which is on the traveling band It is fed forward by the latter the lever k is allowed to finish its course and the lever i is enabled to come into close proximity to the lever t, Fig. 3, thus releasing the lever t at the point 3 In consequence thereof the lever 1) and the shaft '0 are likewise released in order to be again actuated by the cam Z). The lever t" is held by the weight b in the position shown in Fig. 3 until it is raised again by the lever t, Fig. 3.

Continuous feed mechanism, Fig. 1.--As soon as the tobacco has left the mold or former c it is fed in to the traveling band 72., which runs over two rollers h and conveys Over the band it are arranged adjustable bars or ledges Z, which can exactly fit the mold or former c and keep the tobacco in its original form. The motion of the traveling band 71. is transmitted by the main shaft A, with the aid of the connecting-rods 72, 7t3 h 71. and the crank h, mounted on the said shaft A.

Cutting-o]? device with clamping mechan- 'ism.At the outlet end of the hollow space between the traveling band It and the bars l is situated the dividing-knife m, Figs. 4 and 5, which cuts off at a determined angle the tobacco fed thereto by the trayeling band It. It'is moved up and down by the shaft A,

with the aid of the arm m, the lover m the connecting-rod m and the frame in, Fig. 4:. To prevent the tobacco when about to becut off from losing its compressed form and becoming loose, the mechanism shown at an enlarged scale in Fig. 4: and in side view in Fig. 5 next comes into requisition. \Vhen the tobacco is fed by the traveling band 71. onto the bar it, the frame in", Figs. 4 and 5, with its knife, stands at the highest possible position allowed by the mechanism 171 1% m As the knife-frame ascends the pin 0, Fig. 4, bear against one arm of the lever p, which extends across its way and causes the same to turn on its fulcrum p. The other arm of the same lever 11 is connected with a pressing device in the following mannerthat is to say, twolevers q are fulcrumed on q'upon the plate a and engage in the notches or recesses of the guiding-piece 'r, Fig. 4. To the latter piece 9' is fixed the sheet or apron s, which has a shape correspondingto that according to which the cigar is to be enwrapped, and the object now is to increase the opening formed between the guiding-piece and the sheet or apron s before the introduction of the tobacco and during such introduction and to decrease the size of. this opening immediately before the cutting off. As the loverp is turned on its fulcrum by the pin 0 on the frame m ascending the same lever carries away with it one of the arms q, connected with a slotted connecting-rod i; and capable of turning freely on its fulcrm q, whereby the opening between the plate or apron s and the plate at is increased for the introduction of tobacco. Owing to the two arms or levers (1 being connected together by the link 2 the opening of the mold between the apron s and the plate 7t is always fully disclosed, although the lever 19 is arranged on one side of the machine only. The spring a as the frame 171, descends and the tobacco is cutoff effects the closing of the mold, the pin 0 releasing the lever 12 before contact takes place between the knife and the tobacco, so that the latter may be firmly gripped by the mold ere the knife comes into operation. After the latter operation the plate a is turned on its horizontal axis, Fig. 5, and the whole of the mechanism p q r s i it assumes such a position as to offer no obstacle to the tobacco being expelled from above by the plate o The plate a, with its accessorial parts, is swung around by the eccentric-arm n mounted on the main shaft A,with the aid of the connectingrods n n a Emptdsion of the tobacca-The expulsion of the tobacco is effected by a bell-crank lever g fulcrumed on the framework and set in motion by the cam 0 mounted on the main shaft, by the aid of the levers c c Thelever o is provided in front with a plate 1), which can be renewed or exchanged, according to the different forms of enwrapping required. The driving of the remaining parts of the ICC.

mechanism, the motion of which is subsidiary to that of the lever o, fulcrumed on '0 will be described farther on in connection with other devices or appliances. To guide the plate '0 within the mold formed between the apron s and the plate 71 in order to knock off the tobacco, there is fulcrumed at m on the framework a lever w, which by means 'of the roller 12 of the lever 0; causes the mold to be opened. Before the plate o comes into contact with the tobacco the roller c has pushed the lever w to one side and the lever on, Fig. 4, which is connected to the lever 10, is carried away therewith. In the path of the lever 00, Fig. 4, projects the lever q as soon as the plate n, with its accessorial parts, has been turned around its horizontal axis. This lever q is accordingly drawn and operates the opening of mold, whereupon the ram or plate 41 can enter therein. 1

Enwrapping or coiling mechanism-As soon as the tobacco mass or core has been forced out of the mold by the plate o it ar-- .to be able to fully inclose the cigar-core as soon as the rolling appliance has passed over it without interfering with such rolling operation. The rolling appliance varies in shape, according as a cylindrical or conical cigar is required, andis actuated to and fro by the cam H, mounted on the main shaft A, by means of the connecting-rods and levers H H H 11 Figs. 1, 9, and 10. This appliance consists for cylindrical enwrappings of a fork J, carrying a roller J and mounted upon a lever J fulcrumed on J. J 2 is supported by points and is set in motion by the bell-crank lever H fulcrumed on H in such a manner that as soon as H moves forward J 2 is carried away therewith. The counterweight K, Fig. 1, pulls the lever J as soon as the lever H moves backward, likewise to the rear. To wrap up conical cigar-cores, the rolling appliance which is to be used as a substitute for the above is constructed in the following manner, (see Fig. 10:) The lever J is held by the pointed screws L in the bracket L, so as to be free to turn in vertical direction under the action of the connecting-rod H The latter is connected to the lever H and causes it to turn upon its fulcrum on To be able to turn the bell-crank lever J 2 on the screws points L at the same time, the latter is connected to H by the connecting rods'or links H and H so that when the lever H oscillates the lever H assumes a circular n10- tion. In consequence of this motion the distance on one side of the rolling appliance is greater than on the other side, and as a conical roller instead of a cylindrical roller is placed in the fork J a conically coiling or enwrapping is produced. .When the rolling down of the cigar-core over the curved or rolling track G is ended, the same falls subsequently in the gutter or groove G provided at the end thereof, and is withdrawn by hand in order to receive its final covering or leaf farther along. 1 a

As, in consequence of the driving-gear shown fully in Fig. 1, the mechanism 72?, h 72 if, and h and the rollers over which the traveling band h runs are moved sometimes forward and sometimes backward, there must be another device added for the purpose of insuring that the traveling band h will constantly move in the same direction. purpose the rollers over which this band 7t travels are constructed in the manner shown in Figs, 7 and 8. part 1 and an outer part 2, the inner surface of the latter part being provided with suitable cavities or recesses wherein are placed balls of suitable diameter. As the inner part 1 turns in the direction indicated by the arrow shown in Fig. 7, the rollers enter the deep est parts of these cavities or recesses formed in the outer part without carrying the latter part away with them. When,on the contrary, the inner part 1 turns in the direction indicated by the arrow in Fig. 8, the balls 3 are locked in the cavities or recesses of the outer part 2, so that the latter must follow the motion of the inner part 1 of the said rollers.

There remains now to indicate in detail the position of the various driving parts on the two shafts A and B, as well as their mode of operation, which will form the subject-matter of the following paragraph, reference being more particularly made to Fig. 6 of the drawlugs:

Driving-shaft A: h is a cam imparting a motion to the traveling band h. m is an arm actuating the knife m. o is a cam for the knocking-off board c. H is a cam for driving the rolling appliance. n is an eccentric for turning the plate 12 and its accessorial parts around its horizontal axis.
