Be it known that we, O'rro PREISSLER and ANTON FRITZ,

lsubjects of the German Em respectively, at Grossauheim, near Hanau, and Darmstadt, both in Germany, have invented certain new and useful Improvements in Cigar-Machines, of which the following is a specification.

rlhe inventionrelates to machines for making cigars and cigar fillers,` the novel features of which reside more particularly`- in the apparatus for feeding, arranging, and pressing the broken tobacco leaves, of which the fillers are formed, prior` to delivery thereof to the wrapping mechanism,

The invention is illustrated i`n the accompanying drawing, in which:

Figure 1 is a longitudinal section of the Fig. 2 is a section on the line A-B of Fig. 1, drawn to a larger scale. Fig. 3 is alperspective view of a detail, and Figs. l and 5 are views, to a larger scale, of the preliminary molding device and the final molding' device respectively. I

Fragments of tobacco leaf pass from the mixing table into the hopper 1, in which they are slightly agitated by a reciprocating slide 2, the broken leaves then dropping onto an endless conveyer band or apron 3, the upper indicated by an arrow in Fig. 1, toward a vertically moving apron 4. Between the said there is anarrow space through which the leaves are moved for the purposeofl spreading them. Each of the aprons 3 and 4 travels at one end over a squared roller, .so that the aprons havea somewhatjerky movement, which is found to improve the work. The aprons are slightly elastlc, so that they retain close contact with the squared rollers inthe course of the rotation of the latter.

Mel

Underneath the aprons 3, 4 there is ar. ranged a conveyer band 5 moving as indicated in Fig. 1 by an arrow, this conveyer being provided on its face with bars (Lof triangulary cross section whereby V-shaped grooves are formed which extend across the band transversely to the direction of travel of thesame. After having passed between the aprons 3, 4, the tobacco leaves fall into the said grooves formed on the band 5.

Mounted above the front or dellvery end ofthe' conveyer band 5 there is a positively driven fan 7, the vanes'of'wvhich sweep in ose proximity to the bars 6, and by the Specification of Letters Patent. Application le March 27, 1913.

released by the aprons 3 and 4 stamp 10 has, been raised 'of the rotation of the star-fwheel vba'cco as may '203 is cutoil" and also ano Patented Nov. 25, 1913. serial No. 757,216.

draft which they create blow the leaves pro- ]ectlng above the bar ridges into the V- shaped grooves. Those leaves which the fan 7 fails to blow into the groovesjare caught by the bladeswhen passing underneath-the fan,-'and are thus thrust into the grooves. The leaves thn drop oli" the band 5 onto an endlessvco-nveyer band 8 which feeds them to' the preliminary molding device. The band 8 has its delivery end in a slot in the guide 9 of a stamp 10, the latter being raisedl at intervals by lmeans of levers 12 actuated by a cam 11. The stamp 10 is loaded Vwith a weight 13, which, when theraised stamp is cam 11, forces it down by gravity.

Underneath the stamp there is a drum or star wheel 16- which is intermittently rol tated by drivers 14"y on a disk 14:, the drivers being adapted to enter slots ,in a Maltese cross 15, which is lixed to the same shaft as the star wheel 16, so that at every revolution of the disk 14 Athe star-wheel is rotated through 90. The star wheel 16is provided with four primary 4molds 19. Over such mold 19 there are arranged'two slides 20, 20,

the slide 2O being actuated by a lever 21 and the slide 20a by a lever 22. The said levers 21, 22 are connected with one another by gears 23, so that they rock in oppositedirections. The lever 21 has an arm 24 provided 'at its end with a roller, which rides over an abutment 25 when the star wheel 16 rotates, whereby the levers 21, 22 are rocked so that the slides 20 and 20, are moved apart, this occurring when the mold under the slides is in its uppermost position, underneath the stamp 10. The stamp then descends and the tobacco. leaves fed forward by the conveyer band 8 are pressed into the mold. Whei the again the starwheel 16 is rotated through 90, whereby the arm 24 is removed from the abutment 25, and the slides are moved over the mold by the action of a spring 26, so that they. retain the tobacco vin the mold. In the course such toproject between the slides 20, y a continuously rotating circular knife 27, the latter being drivenby bevel gearing 28.. The severed pieces of tobacco are suc ed into a pipe 29. llhe latter, r suction pipe 30, the intake end of which terminates at the lower end of the guide for the stamp 10, are conne'ctedto 110.

. 42 are retracted by a spring 41d.

a pipe 31 leading to an exhaust fan 32. To prevent the sucked particles of tobacco from entering the exhaustfan 32, and direct them onto the eonveyer'band 5, a grid 33 with a slide 34 behind it is arranged inside the suction pipe 31. Immediately in front of the grid 33there is arranged a conduit 35, and branching olf from the pipe 31 behind the grid 33 there is a pipe 36 through which air can be sucked.

The slide 34 is arranged so that when it is moved to cover the grid and close the suction pipe 31 to the pipes 29 and 30, the branch pipe 36 is open, whereas when the slide exposes the` grid so that the exhaust fan can suck through the pipes 29, 30, the pipe 36 is closed by thev slide. case the. particles through the pipes 29 and 30 up to the grid 33, where they are retained by the suction. When the slide is moved so as to cover the grid the fan sucks through the pipe 36, with the result that the tobacco drops down the pipe35. Upon further rotation ofthe starswheel 16 the mold which .has passed the knife 27 is movedV to its lowest position, in which it v discharges the pressed tobacco leaves into the final molding device 37. To allow the pressed tobacco, which is now a filler, to drop out of the mold, the slides 20, must be moved apart again. For this purpose the roller on the arm 24 rides on to an abutment a. yIn order to insure thatv the filler is vdischarged from its mold in the proper position, the base of each mold is formed by a sliding plunger 38, which is connected by va pin 40 with a double armed lever 41. When the mold arrives at its lowest position, the arm 41 of the lever 41 is raised by means of levers 42 actuated by a cam 43, so that the arm 41h of the lever rocks downward and depresses the plunger 38, as shown' in Fig. 4. The plunger is then raised again by a spring 41, and the levers The nal molding device comprises rollers 45, 46,

. which are mounted between plates 47, 48,

of levers 55 actuated by a spring loaded 6 lever 53. The latter is adapted to be used as a treadle, or is automatically actuated by' a cam 54.

After the release of the lever 53 by the foot or cam, the plates 47, 48 with the rollers 45, 46 are rocked toward each other by the spring action, with the filler between the rollers, and the latter perform the second molding operation. After the completion of this operation the slides 51, 52, with the plates and rollers, are pulled apart as shown in Fig. 5, this being effected by means of a train of levers 58 actuated by a lever 56. The latter is used as a treadle, or is actuated by a cam 57. The filler then drops into one of the finishing molds 59. The bi-partite molds 59 are carried by supports 61 on an endless conveyer 60, the rear member of each mold being slidable and `abutting against the arm 62a of a bell-crank 62 pivoted to the support 61. The other arm 62b of the bellcrank projects over the conveyer G0, and lies close to the same, so that when the conveyer is straight the bell-crank cannot rock and allow the slidable mold member to move away from the ixed member. The rollers 45, 46 are disposed above a sprocket 60a round which the molds 59 on the conveyer n the course of this upward travel the conveyer, bent on the circumference of the sprocket, allows the bell-crank arm 62b to `drop, so that the movable mold-member can slide away from the fixed member, whereby the mold is opened to receive the filler. When the conveyer is straightened out again, after leaving the sprocket, it rocks the bell crank and thereby closes the finishing mold, with the filler therein.

That we claim as our invention and desire to secure by Letters Patent of the United States is 1. In a cigar machine the combination of a hopper, a traveling apron in said hopper, a second traveling apron perpendicular to the irst-mentioned apron, arranged with a small clearance between said aprons, an
