Patented in Germany September 23, 1890, No. 58,773; in France November 25, 1890, No. 209,791 in Austria-Hungary February 19, 189L110. 10,031 and No- 26,888; in England August 19,1891, No. 19,281. and in Switzerland NovemberZ, 1891, No. 3.054.

To all whom it may concern.

Be it known that I, JOHANN RUDOLPH SCHMITT, residing at Bingen-on-the-Rhine, in the Grand Duchy of Hesse and German Empire, have invented certain new and useful Improvements in Oigar-Bunching Machines, of which the following is a specification.

Patents for this invention have been obtained in the following countries: Germany, No. 58,773, dated September 23, 1890; France, No. 209,791, dated November 25, 1890; England, No. 19,281, dated August 19, 1891; Switzerland, No. 3,054, dated November 2, 1891, and Austria-Hungary, Nos. 10,031 and 26,888, tom. 41 and 25, fol. 1,851 and 1,735, dated February 19,1891.

This invention relates to machines for forming the bunches of cigars; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side View of the machine, showing the grippers raised and the bunch-rolling table and apron in aposi tion to discharge the bunch. Fig. 2 is a side View similar to Fig. 1, but shows the grippers lowered and the bunch rolling table and apron in a position to receive the compacted filler from the grippers. Fig. 3 is a side View of the machine, taken from the opposite side of the machine from the view shown in Fig. 1, and shows the grippers in a partly-raised position and the binder and compacted filler being rolled together in the bight of the bunch-rolling apron to form a bunch. Fig. 4 is a plan view of the machine from above, showing the clutch partly in section. Fig. 5 is a rear end View of the machine. Fig. 6 is a front end view of the machine. Fig. 7 is an outline side view of the frame of the machine, showing the foot-lever mechanism for starting it. Fig. 8 is adetail side view of the grippers and the bunch rolling table. Fig. 9 is a cross-section through the yoke and the jaws which form the grippers. Fig. 10 is a cross -section through the grippers and shows them in their raised position, with the upper jaw raised to receive the filler. Fig. 11 is a detail side View showing the precise form of the cams I, II, and IV.

The machine is driven either by the crank- .handle 0 on the fly-Wheel c or by the belt-put ley (l, secured on the driving-shaft a. A halffriction clutch e is journaled on the shaft a and has the toothed pinionfsecured to it. The other half of the friction-clutch is splinerl on the shaft a, and is adapted to be thrown into and out of gear by means of the forked lever h. This lever is secured on the shaft 1', supported in bearings lasecured to the frame of the machine. An arm Zon the shaft 11 is connected to the foot-levern by means of the connecting-rod m. A spring n is provided for raising the foot-lever, and the clutch is thrown into gear by depressing the foot-lever, as shown in Fig. 7. The pinion f gears into a toothed wheelf, secured on the shaft 1), which is journaled in the frame of the machine. A cam 19, provided with a recess 12', is secured upon the shaft 11, as shown in Fig. 7. WVhen the foot lever is depressed, a roller 0, carried by the lever 0, which is secured on the shaft '5, is thrown out of contact with the cam. The machine is operated as long as the roller runs on the cam, and stops automatically when the roller 0 drops into the recess 19'. The filling is placed on the endless band '2' which runs over rollers q q, journaled in the frame of the machine parallel with the shafts ct'and b. A toothed pinion s is secured on the shaft of the front roller q and gears into a toothed wheel 25, secured on a shaft 15', also journaled in the frame. A friction-wheel u is also secured on the shaft 15, and is provided with a wedgeshaped groove in its periphery. A frictionpawl u is pivoted to the vertical arm 1) of the bell-crank lever 11 and engages with the said groove. A rod 10 connects the bell-crank lever '11 with one end of the pivoted lever 1, and the other end of the lever 1 is provided with a roller which runs on the cam I, which is secured on the said shaft 1). A springpressed friction pawl U2 is pivoted to the frame, as shown in Fig. 2, to prevent the wheel to from turning backward.

To enable the intermittent motion of the band 0 to be varied, the end of the level-1, to which the rod 10 is pivoted, is provided with a longitudinal slot 1', and the adjustment is effected by moving the pivot-pin in thesaid slot of the lever. A spring 1 is provided for upper jaw 17 anda lower jaw21.

holding the roller of lever 1 in operative contact with the cam I.

The length of the filling is adjusted by means of two bars 5, Figs. 1 and 3, arranged one on each side of the band r. These bars 5 are each connected with a slide 6, guided in an opening in the frame below the band 1". These slides 6 are adjusted simultaneously, as shown in Fig. 5, by the spindle 7, provided with right and left handed screw-threads engaging with the slides. A hand-wheel 8 is provided for turning the spindle.

The filling is separated into portions by means of the two cutters 9 and 10, arranged behind the roller q. Both of these cutters are-carried by a frame 11, adapted to be reciprocated vertically in guides on the frame of the machine. This frame 11 is connected .by means of the links 2, with a pin passing in the slides 12, which slide horizontally in bosses 11 at the upper parts of the sides of the frame 11, and the supports 12 project upwardly through the slots 11 in the said bosses.

A spring 2 is provided for holding the roller of the lever 2 constantly in operative contact with the cam II.

The mechanism for moving the cutter 1O longitudinally will be more fully described hereinafter.

A plate 13 is arranged under the cutters 9 and to receive the filling from the endless band 7". A pair of grippers A is provided for seizing the filling separated by the cutters and delivering it to the bunch-rolling mechanism. These grippers are carried by a yoke A, provided with arms 14 and secured on the shaft 15, journaled in the frame of the machine. An arm 16 is secured on one end of the shaft outside the'frame, and 3' is a rod pivoted at one end to the said arm and at the other end to one arm of the bell-crank lever 3. The other arm of the bell-crank 1ever 3 is provided with a roller, which is constantly pressed upon the periphery of the eccentric III, secured upon the shaft 1) by means of the spring 3. The swinging yoke A is merely a frame for caraying the grippers. The grippers consist, essentially, of an The upper jaw is provided with pins 17', which are pivoted in the yoke A, and 19 is an arm for raising the said upper jaw. A spring 18 is provided and secured to the arm 19 for keeping the jaw 17 in its closed position. A tappet 19 is secured to the frame of the machine for the arm 19 to strike against. In Fig. l the parts are all shown, but the tappet 19 has been moved back out of contact with the end of the arm. When the machine is at work, the tappet is moved forward, as shown in Fig. 10, so that the upper jaw of the grippers is raised when the grippers arrive at their highest position. A discharging-plate 20 is arranged to slide between the two jaws l7 and 21. The plate 20 is provided with two arms 20, and the plate 21 is provided with the arms 21. These arms are guided in the yoke Aat each end of it and are cranked apart from each other and provided with toothed racks, as shown in Fig. 8. Toothed wheels 22 are secured on a shaft 23, which is journaled in the yoke A, and each toothed wheel gears into one pair of racks, so that the plate 20 and the lower jaw are constrained to move simultaneously in opposite directions. One of the arms 21' is also provided with a stop 21 which is adapted to strike a stop 23', secured to the frame, as shows in Figs. 1 and 2, when the yoke A is swung around toward the left. When the said stop strikes the stop 23', the lower jaw 21 is pulled back and the discharging-plate 20 is pushed forward, as shown in. Figs. 2 and 8, and the compacted filler is delivered to the bunch-rolling mechanism. A spring 20 is provided for restoring the said parts to their original positions when the yoke is raised clear of the stop 23'.

The bunch-rolling mechanism is provided with a slide 24, provided with a curved rolling-table 24. A shaft 27 is journaled in the slide below the table, and 26 are two arms secured on the said shaft. The bunching-roller is journaled in the upper ends of these arms above the curved table. Two toothed wheels are secured on the shaft 27, one on each side of the slide 24, and these toothed wheels gear into racks 29, secured to the frame of the machine. \Vhen the slide is reciprocated, the bunching-roller is oscillated in the same direction as the slide. A bar 30 is secured at one end of the rolling-table, and3l is an apron secured to the bar 30, passing over the bunching-roller 25, and secured to the other end of the table. The length of this apron is such that it can be stretched overa compacted filler and its binder when placed on the apron, as shown in Figs. 2 and 3.

Two levers 32 are provided, one on each side of the machine, and are pivoted on the shaft 33. The lower ends of these levers are provided with slots, which engage with the ends of the shaft 27, and the slide 24 is moved back and fo th when the levers 32 are oscillated. A rod 4 is pivoted at one end to a shaft passing through the two lovers 32 and has its other end pivoted to the bell-crank lever 4, journaled on the pivot 34. The other end of thebell-crank lever is provided with a roller, which is held in operative contact with the cam IV by means of the spring 4. This spring also serves to move the slide 24 toward the right in Fig. 1. The upper ends of the levers 32 are connected by a cross-shaft, and a connecting-rod 35 is pivoted to the middle part'of this cross-shaft atone end, as shown in Fig. 4,-andhasits otherend pivoted to the upper end of an arm 37, secured centrally on the shaft 38, which is journaled in the frame of the machine. Two arms 37 are secured-on 'the ends of theshaft 38 outside the frame shaft 38 passes through these slots 39' and operates to reciprocate the rod 39. The slots 39' are provided, and are made of a-length adapted to move the cutter 10 for the desired amount and at the proper intervals.

The operation of the machine is as follows: The filling is placed on the endless band r and is fed forward intermittently to the cutters by means of the cam I, lever 1, rod to, bellcrank 41, friction-wheel u, and the toothed wheels '0 and s. The cutters at this period being raised, a portion of the filling is deposited on the plate 13 under them. The band r then stops and the two'cutters descend simultaneously onto the plate 13, being operated by the cam II, lever 2,and slide 11. The cutter 9 then stops at its lowest position. The cutter 10 is then moved horizontally away from the cutter 9 by means of the rod 39, which is operated by the shaft 38 of the bunch-rolling mechanism, as horeinbefore described. The horizontal motion of the cutter 10 separates a portion of the filling and delivers it to the grippers A, as shown in Fig. 10. The cutter 10 is then moved out of the way, so that the path of the grippers is not obstructed. The eccentric III then permits the yoke A to swing over toward the left from the positions shown in Figs. 1 and 10. The lever 19 leaves the tappet and the upper jaw compresses the filler against the lower jaw. The continued motion of the yoke A brings the parts into the position shown in Fig. 2, and the stop 21, having struck the stop 23, the lower jaw 21 is pulled back and the dischargingplate 20 is pushed forward to deliver the compacted filler to the bunch-rolling mechanism. The binder has previously been laid on the surface of the apron and is under the compacted filler when the latter is discharged from the grippers. The compacted filler and the binder are now rolled in the bight of the apron by means of the bunchroller and its actuating mechanism hereinbefore described, and the completed hunch is discharged at the rear of the machine. The swinging yoke and the grippers are raised while the bunch-rolling mechanism is in operation, and more filling is delivered upon the plate 13 under the cutters without any delay and before the said cutters descend again.
