CIGARfBUNCHING MACHINE.

SPECIFICATION forming part cf Letters Patent No.364,815, dated .Tune 14, 1887.

Application filed Octobcr17, 1884. Serial No. 145,759. (No model.)

sleeved upon said shaft, and provided with two upright forked arms engaging the gudgcons of the oscillatingroll and operating in conjunction with said segmental rack, and a series of auxiliary levers to oscillate said roll horizontally in a right line in elongated slots in its'journatboxes, and a segmental drum adjustably secured upon said motive shaft and combined with an apron, to which it imparts a reciprocating movement over saidv rolls. There are also means provided for taking up i the slack or throwing out the pocket formed between the rolls, whereby the bunch is discharged from the machine.

Strueturally, my invention may be divided into three systems of mechanism-namely, mechanism for rotating the rolls and operating the carrying-apron, mechanism for oscillating the movable roll horizontally in a right line to separate the rolls for the insertion of the filler or the discharge of the completed bunch, and mechanism or means for taking up the slack of the apron to discharge the bunch.

y Heretoforein forming a cigar-bunch by a machine it has been necessary after rolling one bunch to reverse the machine and start from the original position to roll the next bunch. In my invention a complete bunch with its binder is rolled with each forward or backward movement of the apron and its carrying mechanism, thus rolling alternately a right-hand binder `and a left-hand binder, the machine opening always toward the `front thereof at the end to each forward or backward movement to disch arge a complete bunch and receive the filler and binder for a second bunch. Y

So far asl am aware,dru1ns in cigar-bunching machines have alwaysY been heretofore made with closed surfaces, and great difculty has been experienced from the accumulation of scraps and refuse upon the surface of the drum underneath the apron, thereby diminishing the capacity of the pocket and reduc ing correspondingly the size of the cigarbunch, producing bunches ot' variable size. These difiiculties are wholly avoided by making the drum sufficiently open upon its surface to allow all substances falling upon it to drop through, thus keeping the surface at all times clear and insuring aproduet uniform in size and density. Special' reference is therefore made to the skeleton open form of the drum G.

The accompanying drawings forni a part of this specification, and represent what I con sidcr the best means of carrying out my invention.

The reciprocating roll D and stationary roll C, whose gudgeons are journaled in the upper part of the frame A A, are rotated by pinions n a upon their ends, meshing into sp ur-whoels m m, which in turn mesh with a segmental rack, R, keyed to a motive shaft, S, journaled upon the side of the frame A. The spurwheel m is journaled in the short arm of the bifurcated bent lever K, and the arrangement is such as to keep the pinions n n' always in mesh with the segmental rack. A segmental drum, G, is adjustably secured upon the said motive shaft by set-screws, as shown clear] y in Figs. 1l and 12. To this drum is attached by each end, to oscillate with it, an apron, F, which passes over the two rolls C D, and is made of suiiicient length to be crowded down between them to form a pocket. This drum is made in skeleton form to allow dust or tobacco scraps falling from the rolls or the apron to pass through it, and thus prevent their accumulation under the apron, which would tend to take up the slack in the apron, reduce the size ofthe pocket, and produce irregular work.

It will be observed from an inspection of Figs. lil and l2 that the drum G- is formed of two sections (each of which is a quadrant) carried upon the main driving-shaft by means of sleeves and setserews. From this construetion the positions of the sections may be varied with relation to each other, so that the pocket may be made of any desired size. The

reciprocating roll D is adapted to move in the'.

elongated slots s sin the frame A A. It is parallel with the roll (l, and its gudgeons, together with those of the roll C, are journaled in the boxes E E. The horizontal reciprocation of the roll D in the slots is accomplished as follows: The gudgeons of the said roll are engaged by the forked ends of thetwo upright arms J' J2 of a U-shaped lever, J, adapted to work looselyT on the shaft S. vOne of the arms, J,of the Ushaped lever is provided with the lug Z', so 4positioned as to engage with a similar lug, l, on one of the radial spokes of the segmental rack, whereby, in the forward oscillation of said rack, the arm J will be moved, carrying with it the roll D. This movement continues until the said roll is sufficiently separated from the roll G to allow the apron to be pushed down between them bythe hand of the operator to form a loop or pocket. The rack is then oscillated in the opposite direc tion, and the springs Z Z act meantime to return the roll D to its normal position, where it, in conjunction with the roll C, forms a bight in the apron. After the bighthas been completed the rack, continuing its backward movement, brings aseeond lug, r, on its spoke into engagement with a bell-crank lever, P P, which, through the link T, draws upon the downhanging arm J 0f the lever J', and thus throws forward the upper end of the said lever and separates the rolls. The roll D is again moved to the rollei1 C by springs Z Z, to

form the pocket while the rack is moving forward, and remains in its normal position until the lugs t l again meet. In this manner two pockets are formed with each oscillation of the rack; or, in other words, the rolls C and D are brought into position for forming a completebunch once with each forward or backward movement of the rack. By this arrangement no time is lost, as in other inachines, where it is necessary to return the mechanism to start from its normal position.

The oscillating movement is imparted to the shaftS, rack, the., by means of the driving wheels W YV and the treadles y y. The rope or band 7 from one of the trcadles passes to the left and over one ofthe pulleys,to which it is fastened at a point to the right. The rope S from theother trcadle passes to the right and over the other pulley in the opposite direction, heilig secured thereto at a point to the left. Obviously, to move lthe rack, Sec., to the right, it is only necessary to draw upon the rope S and to move it to the left. The other rope is then brought into use. The roll D is retracted to and held in the closed position near the roll C by coil-springs Z Z, ex tending from its gudgeons to pins or lugs on arms attached to the side of the frame and lprojecting back beyond the stationary roll.

After the bunch has been formed and the rolls separated it is necessary to take up the slack in the apron, as before stated, for the purpose of discharging the bunch; and for this purpose I have provided two methods-first, by the handof the operator, as before described, and by the following device: A weighted roll, H, is journaled in arms of a stirrupshaped frame, a, which has gudgeons journaled in the sides of the rnaeliinefame in such position as to bring the roll over the apron and a little behind and below the stationary roll C, before described. An upright catch, c, pivoted to the inner side of thcframe of the machine, engages a projecting pin on said stirrup-shaped frame to keep the wei ghted roll suspended above the apron. This catch is joined to a horizontal-acting latch, c', hookloo IIO

ing onto a projecting pin, n, on the outer side of the right-hand arm of the U-shaped lever before mentioned. To the frame of the machine, on its inner side, nearer the front ofthe machine, and in the line of travel of the latch, is another projecting pin, e'. As the arm of the Ushaped lever J travels toward the front of the machine to reciprocate the movable loll, as before described, it draws the latch c with it and trips the catch to release the weighted roll, allowing it to fall upon the apron and draw upthe slack therein. There the continuance ofA the forward movement of the lever-arm causes the latch to ride on the second pin, releasing the latch, which is then drawn back by a spring, t, (extending at an angle in a downward direction from it to a lug on the inner side of the 1nachineframe,) thus bringing the catch into position to engage its pin,

when the weighted roll is thrown up from the apron in forming the pocket.

To practically operate my invention, suppose the rolls apart and the segmental rack at the extreme limit of its forward movement. The apron will then be taut, its slack having been taken up by the weighted roll or the hand of the operator, as described. The operator places his hand upon the apron between the rolls, and by a downward movement forms the pocket, and by the same movement either throws up the weighted roll to engage with its catch or takes up the slack between the rolls D and O. The pocket being formed, the filler is placed therein with a binder laid upon it, the operator relieves the pressure upon 'the treadle and rope 8 and allows the springs Z Z to exert their force and move the roll D up to the other roll, C. Pressure is then applied to the treadle y, which draws upon the rope 7 and imparts to the shaft, rack, and skeleton drum their backward oscillation,which movement causes the apron to travel about the rolls, and also gives the necessary rotation to the rolls themselves through the pinions n a and spur-wheels m m. The roll D remains in the position it has now assumed, operating in connection with the rollCto form the bunch until the rack in its continued backward movementv brings the lug r on its spoke into engagement with the arm I of the bell-crank lever. .The bunch has now been completely formed, and is in proper shape to be discharged from the machine. The lug r pressing upon the bellcrank lever causes it to draw upon the link T, which, through the depending arm J3, throws forward the upper part of the lever J and separates the rolls. The completed separation of the rolls being effected, the operator places his hand upon the apron at a point between the rolls C and D, and by a downward pressure takes up the slack between the rolls Gand D, and thus discharges the bunch from the machine, or, should the automatic mechanism be used, the slack is taken up by it, as before described. After the discharge of the bunch the operator again formsapocket between the rollsCand D, and thenreleases the treadle, allowing the roll D to move back by the force of the springs. The machine is now in position for forming a bunch on the return or forward oscillation of the shaft, rack, and drum, and the operator accomplishes this by placing his'foot upon the treadle to draw upon the rope 8. The forward oscillation is accompanied by the same effect, namely, the rolling of the bunch, which continues until the lug l strikes against the corresponding lug Z on the lever J, when the rolls will be again separated and the bunch discharged, as described above.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
