6 Claims.

'Ihe object of this invention is to devise a novel cigar wrapping machine which will operate fasterv than machines now in use, which will eliminate operations heretofore deemed essential and which will materially reduce the number of parts heretofore employed with a consequent reduction inthe cost. of manufacture.

A further object of the invention is to devise a cigar wrapping machine which will duplicate hand operation.

A further object of the invention is to eliminate all leaf carriers and the operation of transferring the leaf from the cutting die to leaf carriers, and also stretching devices. y

A further object ofthe invention is to provide a definite speed relation between the rack and gear movement and the linear travel of the rolls over .the Wrapper. l n

VA further object is to provide the crank'with a cam capable of moving the rack rearwardly to increase the tension if more tension is desired on the wrapper.

A further object is' to devise novel means to hold down the die plate while the knife rolls'are cutting the wrapper. 'I'he holding means provide clearance for the rollers while moving over the die. The die plate raises when the wrapping machine is in position for tucking needle operation;l This allows the cigar to rest on the die plate and prevents wrinklingof the wrapper.

A further object is to have the cutting arms operated by the movement of the carriage, thus eliminating cams and their timing.

A further object is to have a crank arm motion `which controls practically all movements of the machine. f

A further object is to devise novel means to control a tension plateto hold the wrapperV in exact position relatively to the head of the cigar. Wththe above and other objects in view as will hereinafter kclearly appear, our. invention comprehends a novel cigar wrapping machine.

Other novel features of construction andadvantage will hereinafter more clearly appear in the detailed description and the appendedclaims. For the purpose of illustrating the invention, we have shown in the accompanying drawings a typical embodiment of it, which, in practice, will give reliable and satisfactory results. It is, however, to be understood that this embodiment is typical onlyand'that the various instrumentalities of which our invention consists can be-variously arranged and organized, and the invention is not limited to the precise arrangement and f* Figure 7 is an end elevation showing ticularly the driving means for the bunch carryvling mechanism.

Referring to the drawings: I designates the frame of the machine, the

I construction and -arrangement of which can vary widely in practice. i

.Themachine is driven by a motor 2 having its shaft provided with a pulley 3 around which passes a belt 4 which latter also passesy around suitably journalled The crankshaft has a disc 33 with a wrist pin The upper end vof the lever I0 has a stud I2 connected byla link I3 fwith a stud I4v secured to a bracket I5 fixed to a reciprocatory carrier IE of the rolling mechanism.

This carrier I9 has rollers I1 which roll on bars i8. Attached to the carrier I6 is a carriage I9 in which is journalled a shaft 29. A pawl plate 2|, see Figs. 8 and 10, is fixed to one end of the shaft 29, and carries a spring pressed pawl 22, which cooperates with a ratchet 23 to be driven thereby. The ratchet 23 is secured to a gear 24, loosely mounted on the shaft 29. The gear 24 receives its motion through a rack 25 as the carriage moves over the rack, see Figs. 1, 2, and and, independently, by a cam movement consisting of a stud 26 on the rack, a link 21 connected with the stud 28 and a stud 29, the latter being connected with a cam lever 29 fulcrumed at 39 on the frame and havinga roller 3| which rides.

on a cam 32 on the crank disc 33 Vto which the wrist pin 1 is secured, see Figs. 1 and 2. The

rack 25 is free to slide in the ends of the main frame.

A gear 34is fixed to the shaft 29, see Figure 8, and drives a gear 35 on a fluted roller shaft 39 journalled on the carriage I9. The shaft 36 has fixed to it a gear 31 which drives gears n39, see Figure '1. The gears 38 have fixed to them gears 39, and both gears are free to rotate on their shafts 49, and free to rock in thel carriage I9. Also mounted on the shafts 49 are rock arms 4| and 42, see Figure 4, in whch fluted rolls 43 are free to revolve, and. on the ends of the rolls, gears 44 are mounted whch are drven `by gears 39.

The Fluted rollers support the bunch and rotate it.

The bunches are fed from the bottom between the fluted rolls, either manually or mechanically in any conventional manner.

The rock arms 49, are tensioned, by springs 45, against `adjustable stops 46, secured to brackets 41, on roller frame I9. A

The tuclcz'ng needle 49 is the tucking needle, see Figure 6, secured to a rod 49 whichl is free to rotate and to move longitudinally in a bearing 59 on the carriage I9. The rod 49, at the end opposite the needle, has spaced collars 5I fixed to the rod. The free end of a drying member 52 extends between the collars and is connected to a lever 53, fulcrumed on the carriage I9. A lever 54 pivoted at 55 to the carriage I9 has the rod 49 passing through it, and raises and lowers such rod and the tucking needle. The lever 54 has an arm 59 fixed to it and the lower end of such arm is in the path of a cam 51. The downward movement of the lever 54 is limited by an adjustable stop 58. The cam 51 is formed on a lever 59 fulcrumed on' the machine frame at 99, see Figure 1. The lever 59 is-connected by a link 6| with a lever 62 fulcrumed at 39, and provided with a roller E3 which cooperates with a cam 64 on the crank disc 33.

The lever 53 has a roller G5, which cooperates with a cam 96 on the lever 59 to move the needle rearwardly.

The forward movement'of the needle is caused by a stud 91 on the lever 53 contacting with the cam 96.

T'he shaft 29 has fixed to it a ratchet 98, see Fig. 4, cooperating with a pawl 69 to prevent rearward rotation of the uted rolls. The carriage I9 has bars 19 and 1|, the latter being fixed at its lower end to a rod 12, mounted. in a rock bracket 13, carrying a plate 14, tensioned by a spring 15. The head end of the leaf adheres, due to the paste applied to it, to the bottom of the plate 14 after being transferred from the cutting plate to cause a tension on the wrapper, so that the head end of the cigar can be smoothly wrapped. The carriage I9 has a stationary knife 16, see Figures 3 and 4, on which is pivoted at 11 a movable knife 18. The movable knife is in the form of a lever having an arm 19, connected by a link 80 with a lever 8|, fulcrumed at 82 on a bar 83, secured to the support I9. A spring 84 actuates the movable knife. The lever 19 has a trip stop 85 which cooperates with a stop 86, fulcrumed at 81 to hold the movable knife open.

The upper end of the lever 8| contacts with a roller 88, see Figs. 1 and 13, to open the movable knife. The roller 88 is mounted on a stationary bracket 89 xed to the main frame.

A bracket 9|), fixed to the bracket 89, forms a fulcrum for a lever 9|, held by a spring 92 against a stop 93.

Secured to the carriage I9, is a header block 94, see Figure 3, shaped to suit the end of the cigar. 95 is a cone shaped roll free to revolve on Ya stud 99, on a lever 91, pivoted` at 98. The other `end of the lever 91 is slotted at 99 to receive a stud |99, secured to a lever IDI, fulcrumed on a shaft |92, on a bracket |93, on the bracket 83, see Figure 3. The shaft |92 has a lever |94, having fixed to it a stop |95, which is pressed against a lever |96 by aspring |91. The lever |96 is fulcrumed on a stud |98 secured to the carriage I9. An arm |99 extending from the lever |99 travels 'in the path of a lever IIU, see Figs. 14 and l5, moving the lever |86 away from the stop vv|95. The lever ||9 'is pivoted on a stud III on they support I9. The upper end of the lever ||9 has secured to it a spring II2, of sufficient strength to trip the lever |96.

The other end of the spring I I2 is secured to "a lever' I I3, mounted on the stud I I I, and having The die mechanism |24 'is a cutting die, see Fig. 11, secured to a die box I 25 fixed to the machine frame and hav- `ing suction holes |26 at its top. Inside of the die and free to move upwardly and downwardly, is a suction plate v|21 having suction holes |28. The

suction plate is fastened to a rod |29, which is guided ina bear-ing sleeve |39 on the box |25. The rod |29 has a slot I3I, into Which a lever |32 extends to hold the die plate downwardly. The lever |32 is. in the form of -a plate and is ful- *crumed at |33 on the die. box |25. The lo-Wer end of 4rod |29 has a pin and slot connectiony at |34l with a lever |35, fulcrumed at |36 .on the main frame.v A cam |31, mounted on lever |35, cooperates with a roller |38 mounted on a lever |39, which is secured to the rock shaft II. A spring |49 secured to the lever |35 tends to raise the die plate |21.

A lever 4| fulcrumed at |42 on the main frame, see Figure 1, has, at its free end, a stud |43, which bears against the lever |32 to move `it out of the slot |3I of rod |29, such action being causedfby one end of the lever I4| engaging a fixed stop |44 on the roller frame I6.

Th die plate has a slot |45 into which the tucking needle is adapted to pass.

The operation of' the machine will now be which turns. lever 53 to withdraw the tucking needle.

readily apparent to those skilled in this art and All of the operations of the machine are controlled by'a common crank shaft which has a 'The'.A machine starts and rollers V| I1 carried by arm. |9 are moved over the die. Y When. the roller |22, see Figure 1, lmoves forwardly .in the cam track |23, the rollers travel over the die |24 and die plate |21 causing the leaf of tobacco to be cut to the contour of the die plate, thus forming the wrapper. `When the rollers are returning the operator strips the'excess leaf off of the die block |25, and applies paste to the head end of the wrapper. During this operation the die plate |21 is in its downward position, being held by pawl |32 in slot |3|, see Figure 11.

During the time the rollers are cutting the leaf, the carriage I9 has moved forwardly to the position at which the cigar is to be inserted. As the carriage |9 passes over the die plate |21, its motion stops at the point where the tucking needle 40 is in alignment with slot |45 in the die plate |21. At this time, there is a dwell in the movement as the crank is going over dead center. As the carriage is moving back the pawl lever 54 rides on the cam 51, see Figure 6, causing the forward end off the tucking needle to move downwardly to be in alignment with the slot |45, so that it can pass beneath the wrapper. At this time the pin |44., see Fig. y1, contacts with lever |4| causing pin |43 to push lever |32 out ofthe slot |3|, allowing the die plate to move upward due to spring |40.

The tucking needle is moved into .the slot by the roller 63 engaging cam 64, see Fig. 2, and moving cam lever 62, link 6I, and lever 59 on its pivot. The stop lug 66 is engaged by the rod 61 on the lever 53, see Fig. 6. This causes the link 52 to move the tucking needle forwardly into the slot |45 beneath the wrapper. As the tucking needle moves in, the arm 56 passes over the cam 51, and the lever 54 moves downwardly, raising the tucking needle against the bunch. Now the carriage starts forwardly to roll the wrapper around the bunch.

During this forward motion, the speed of the fluted rolls 36 and 43 may be varied to rotate the bunch faster than it is passing over the die plate to obtain a desired stretch in the leaf. This motion is produced by moving the rack in the vopposite direction to the movement of the carriage, through link 21, lever 29 and roller 3| riding on cams 32 secured to crank disc 33.`

Movement is imparted to the fluted rolls 36 and 43 from the rack by the gear 24, see Figures 5 and 8.

The tucking needle being pressed against the cigar rotateswith the bunch in its journal 50. After the end of the leaf is tucked in, or about one and one half revolutions, the needle is withdrawn. As the roller 63 rides over its cam 64, the lever 59 is returned to its normal position, bringing the stop lug 66 against the roller 65;

` As the carriage moves forwardly to the head end of the cigar, the tension plate 14` moves over the head end of the wrapper, and the die plate I |21 moves downwardly allowing the wrapper to `adhere to the tension plate 14. The die plate is moved downwardly by cam |31 contacting with roller |38 on moving arm |39, at which time, the plate |32 enters slot |34 holding down the die plate. Thedownward movement of plate 14 is limited by a stop |46, see Figure 4. At the proper time, just before the flag of the wrapper is wrapped around the bunch, a portion of the flag l is adhering .to the vertical portion of the tension plate 14. At this time, the movable knife 18, .which is in its open position, now operates and nicks the wrapper. At this time the cone shaped header roll moves in against the bunch, causing the wrapper to be wrapped conically around the head of the bunch. The movable knife is pivoted at 11 on the stationary knife 16. The lever 19 is a part lof the movable knife and is operated through link 80, lever 8| and spring 84 to hold the movable knife closed.

As the carriage |9 moves forwardly `to the end of its stroke, the free end of the lever 8| contacts with the stationary roller 88 opening the movable knife; at which'time the lever 86 pivoted at 81 moves over a vvnotch in the plate 85, holding the knife in open position. A spring |41, see Figure 3, holds the lever 06 in holding position. The knife is permitted to operate during .the forward movement of the carriage by the free end of the lever 86 contacting the lever 9| disengaging the lever 86 from the notch in the lever 85. The lever 9| is heldby the spring 92 against the stop 93. On. the return of the carriage, the movable knife remains open due to the spring mounting of lever 9|.

The header roll 95, on lever 91 is moved by the arm |09 contacting the lever ||0, seeFigures 14 and 15.

The arm ||0 is prevented from moving by the spring I2, which is of sufficient strength for this purpose. The lever ||0 is retained in position against the stop ||4 on the lever ||3. The lever I3 is held in position against the stop |6 by the spring ||5. As the stop |09 is moved, the lever |06 moves away fromthe pin |05, allowing the lever |04 through the spring |06 to move. The lever |04 is fast on shaft |02 and rocks lever |0|, and, through pin |00, see Figure 3, in slot 99 moves lever 91 inwardly.

The cigar is removed from its carrying rolls by moving the bell crank levers which support the lower uted roller.
