HERMANN KORTE, OF VAIILERSHAUSEN, GERMANY.

CONTINUOUS-CIGARETTE MACHINE.

SPECIFICATION forming part of Letters Application filed September 28,1894

To all whom it may concer-n:

Be it known that I, HERMANN KORTE, of VVahlershausen, near Cassel, in the Empire of Germany, have invented certain new and useful Improvements in Continuous-Cigarette Machines, of which the following is a specification.

This invention relates to improvements in rod of loose tobacco or fillings is continually compressed and enveloped in an endless paper band or Wrapperand the seam of the latter is closed by a folding arrangement; and the objects of my improvement are, first, to make the forming channel and the forming wheels adjustable; second, to better fold and roll the wrapper seam; third, to provide a mechanism, whereby the circumferential velocity of the crimping Wheels is made like the velocity of the continuous cigarette; fourth, to afford facilities for the proper indenting of the folded and rolled Wrapper seam; fifth, to provide a press roller for leveling the indented folded Wrapper seam, also for making the cigarette oval in section, if so preferred; sixth, to make the apron reliable and adjustable. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a ground plan of my improved continuouscigarette machine; Fig. 2, a side elevation thereof; Fig. 3, an end View thereof; Fig. 4c, a cross-sectional view taken ou the plane of the line 7 s, Fig. 1; Fig. 5, a cross-section taken in the planeof the line'zl 7c, Fig. 20; Figs. 6, v7, S, and 9, various views of certain parts to be described later on; Fig. 10, a crosssectional View of the machine, taken in the plane of the line n o, Fig. 1; Fig. 11, a view from below at the lever O2 shown in Fig. 10; Fig. 12, a crosssectional View of the machine, taken in the plane of the line 1o q, Fig. 1; Fig. 13, a vertical longitudiualsection taken in the plane of the line t u, Fig. 1; Fig. 14, a crosssection on enlarged scale through the line a b of Fig. 13; Fig. 15,a cross-section through the line c d; Fig. 16, a cross-section through the line ef; Fig. 17, a cross-section through the line g h; Fig. 18, a cross-section through the line 'L' 7o; Fig. 19, a cross-section through the line Z m of Fig. 13; and Fig. 2O a horizontal sectional View of the machine, taken in the Eatent No. 541,364, dated June 1s, 1895.

plane of the line v w, Fig. 13. Figs. 21 to 2l show parts of the `feed-apron, and will be rej ferred to later on.

Similar letters of reference indicate corre- On the four columns U4 U4 erected on the table A a head plate U is fastened for the purpose of holding the two axles Q Q (Fig. 12). The one axle Q, pivote-d in the bearing S2 on the table A and in the bearing S in the head plate U,is made adjustable by means of the screws Q2 in the bracket A4 and U2 in the plate U' on the head plate U. In a similar manner the other axle Q', pivoted in the box S2 and in the bearing S', is made adjustable by means of the screws Q2and U2. Onthe axles Q Q two crimping Wheels R Rare fastened, which are finely toothed at the circumference and work together.

Immediately under the crimping wheels R R are two adjustable forming Wheels, which revolve on the axles Q Q and consist in the upper halves X X3 and in the lower halves X2 X4. Thelatterare threaded in the borings to tit to the equally threaded bosses of the upper halves X X2` so that they can be moved up and down, their lower parts being outside formed like nuts (Fig. 13). In this manner the furrows at the circumference of the forming wheels can be regulated according to the diameter of the continuous cigarette H.

The machine is driven by means of the shaft M (Fig. 1), which may be turned either by hand or through some suitable means from a machine making the continuous rod of loose tobacco or fillings. The motion of the shaft M is transmitted through the bevel Wheels N and N (Fig. 10) and the gear wheels P and P (Fig. 2) to the axles Q Q. )Vhen the machine is driven, not only the crimping wheels R R revolve, but also the forming Wheels X X3, X2 X4, to which motion is imparted through the gear Wheel V fastened on the axle Q and through the gear Wheels V W iV sitting on the bosses of the forming wheel halves'X X2. The two gear Wheels W W are alike, While the gear wheel V is a little larger than the other V. For this reason the lforming Wheels X X3, X3 X4 run 'a little quicker than the crimping wheels R R', and in such a manner, that the Velocity at the periphery of the crimping wheels R R is like that of the mean circumference of the forming Wheels X X3 X3 X4 and also like that of the continuous cigarette H.

The forming channel B is best shown in Figs. 13 to 19. It is open at the top (see Fig. 1') and is covered with a steel tongue D. At the front end it lis flat as shown by the cross section Fig. 14 to facilitate the entranceof the wrapper G, which is introduced over the guide pulley G. The channel B is hollowed out conically about from trestle A to trestle A3 to properly compress the tobacco fillings and to gradually envelop the same with the wrapper G. The end piece C is, however, bored cylindrically, slit at the top (Figs. 7, 18 and 19) and fastened to the channel B by means of theserews C3 C3 C3 5). Tointroduce the rod of fillings Il (Fig. 13) and the endless wrapper G into the forming channel B an endless feed apron I` is employed, which goes over the flat front end of the channel B into the latter and round the pulley K. The two cross bars D2 D5, fastened on the channel B by means of the screws D4 D3, serve to hold the steel tongue D. The one cross bar D3 is on its under side provided wil h two deep cuts D3 D3 (Figs. 9 and 17), which converge in the direction to the end piece C. To the cross bar D3 the steel tongue D is fastened only in the face shown hatched in Fig. 9. The steel tongue D is kept at a certain distance from the inside of the channel B, so as to leave on both sides narrow slits for the passage of the l bordersl of the wrapper G and of the apron I.

See Figs. 15 to 17. Thusthe steel tongue D not only compresses the fillings H, as they proceed in the channel B, but it also enables the two edges of the wrapper G to risecontinually and to approach each other over its upper surface. On arriving before the cross bar D3 the edges of the wrapper G are obliged to bend upward in order to travel through the deep cuts D3 D3 (Fig. 17). Here they are drawn nearer and nearer until on the exit they touch each other.

As said above, the end piece C has at the top a slit C3, which is shown in Fig. 7 exaggeratedly wide for the sake of clearness,fwhile in reality it is so narrow as to allow only of the two wrapper edges passing through. The top face of the end piece C is alittle above that of the channel l5 and is provided with two inclines C4 sloping to the slit C3. Into the furrow thus formed a die F (Figs. 13, 1S and 19) is fitted. It is fastened to the springr E by means of screws (Fig. 6) and is provided on its under side with a conical furrow F converging toward the exit. The spring E is .v connected with the cross bar D3 and made adjustable by means of the set-screws E E3. -It is capable of being bent a little upward, so as, to clean the furrow F of the die F. The spring E may also be fastened to the cross bar in its place.

less wrapper G touch each other on leaving."`

the cuts D3 D3 of the cross bar D3. When `farther proceeding, they enter the narrow slit.` l C3 and are thereby folded, so that they stand quite vertically. On reaching the die F, they are obliged by its furrow F to bend and `t0 1 roll more and more. On leaving the die F the rolled seam of the wrapperGis caught bythe l ne teeth of the crimping Wheels R R and indented or crimped, so that the seam is now prevented from opening again.

To insure this purpose, the lower end of the axle Q'f. 3

(Fig. 12) is fitted in a box S3 which can turnon the two pins S4 sidewise, while the upper end is in a bearing S which is pressed with the spring T3 by means of the screw T. Thus -4 the two crimping wheels R Rare pressed toa` gether so that their teeth crimp the wrapper" seam tightly.

Above the pulley K a press roller Y (Fig. t

13) is arranged in a frame Y3, which is connected at U3 (Fig. 1) to the head plate U by the pin Y and is made adjustable by the setscrew Z3. The latter is in an arm Z which can beswung about on the column Z. On

the axle of the press roller Y agear wheelY is fixed, which gears into the long pinion Y".

The pulley K is also toothed at one side and gears into the pinion Y, so that its motion is thereby imparted to the press roller Y. To insure a good working of the machine the pulley K, the press roller Y and the gear wheel Y3 are made of an equal diameter. The pinion Y4 is pivoted in an arm YS, which is adjustable on the column Z and may be put aside if desired.

The press roller Y serves for leveling the folded and crimped seam of the continuous cigarette H and also, where wanted, for flattening the cigarette, t'. e., giving it au oval section. (See Fig. 10.)

When a continuous cigarette of anotherdiameter is tobe made, the forming channel B will have to be replaced by another one and the forming wheels X X3, X3 X4 are readjusted to fit to the diameter of the cigarette.

The apron I is kept in tension by means ot the two pulleys l and I3. The one pulley I (Fig. 13) revolves on the shaft L3 (Fig. 4), which is pivoted in the bearing Land carries at the one side the short lever L2 (Fig. 2) and at the other side the, ratchet wheel L3. the boss of the bearing L' a lever L is turnable, which carries a weight LT and is provided with apawl L5 at the short arm L.

its),

Thus the pressure of the weight L7 is transmitted through the lever L, the pawl L3, the

ratchet wheel L6, the shaft L3, the lever L3 andthe pulley I2 to the feed apron I. ,To prevent the feed apron I from slipping on the pulley K, the latter is finely serrated and moreover the apron is in the following manner pressed against the pulley K. The bevel Wheel N turning round the bolt A3 (Fig. l0) has a long boss, on whichthe gear wheel P slides up and down, While it is obliged by a feather to partake in the revolution of the bevel Wheel N. On the gear wheel P an india rubber ring O is fastened in a suitable manner, while on pins O2 below the gear wheel P a lever O3 is turnable, which carries at the longer arm a weight O4 and at the shorter arm a friction Wheel O bearing against the gear wheel P. VIt will now be seen, that the pressure of the weight O4 is transmitted through the lever O3, the wheel O', the gear wheel 'P and the ring O to the feed apron I.

The feed apron I is made of two or several layers of tracing cloth pasted together in the manner indicated by Figs. 2l to 24. The ends of the tracing cloth strips in every layer butt at each other and the butts in one layer do not coincide with those in the next layer. Thus the butts ct and b in a twofold apron shown in Figs. 2l and 22 areinterposed, The same refers tothe butts a, b and c in a threefold apron. Shown in Figs. 23 and 24. In Figs. 22 and 24 the layers of the tracing cloth in the apron I are shown exaggeratedly thick for the sake of clearness. Thus an endless apron is obtained, which is throughout of the same thickness and lasts much longer than an apron with seven joints would, because the joints of the latter are not only thicker, but are also liable to wear and tear. Owing to this construction of the feed apron I the latter cannot be inserted in the channel B through the fine slit C3 (Fig. 7). Therefore the end piece C is made in two halves .united together by means of the screw C (Figs. 5 to 7). To insert the feed apron I in the channel B, one half of the end piece C is taken off, then the apron I is introduced and afterward closed in by putting the half on again.

The forming wheels X X2, X3 X4 serve to draw the feed apron I with the continuous cigarette Il out of the forming channel B. To insure this, they may also be covered at the circumferences with india'rubber.
