in Germany a tobacco less finely In all casesV the problem is to separate a strictly definite portion from the supply of filler tobacco and work it into a filler. have been'prop'osed in which In the manufacture of cigar llers variably subjected to forcible operations.

-These operations are extremely harmful to the condition of the lfiller tobacco in the filler. It is very important -that the sensitive strips of filler unimpaired and not fracture, crumbling,

tobacco should be kept vand the like.

By means of to allow the cut ller tobacco ly, without the ,employment of any Vforcible measures, from the supply to the pressing position. In the course of this operation the tobacco 'isl exactly portioned. Forv this purpose the tobacco inserted loosely `in av supplyA vessel, is `passed continuously in mass to a collector vessel vrby means ofv aV stirring device or the like, and fromvthe collector vessel one portion of tobacco after the other-is lremoved by means of a measuring receptacle.

A shaping channel lwith "a shaker is provided, in which the tobacco is poured loosely and then pressed into the shape of a ller.

In this manner the filler 'tobacco is not subjected to the slightest stress by pressure, com- "pressionor the like on its passage fromv the sup- Iply to the ller press,'it does not come into any contact whatever with mechanical separators in the form of channel pushers, rotating chambers, "or the like,'but vit alwaysremains in loose con- "dition "until the moment when itis formed in the filler press. f

It is advantageous if to the sack-like container with the measuring `receptacle according to my-copending applicathe material, which `is fed tion'Sei-ial No.v 415,295, is deposited on a rcircular Aor disc-shaped surface and thrust towardsan 'outlet in the disc by scraper plates extending radially over `the stationaryr disc surface. The `material passes through the outlets into the sack; itis obvious that the movement of the :scraper must be suitably correlated to the movementsV of the measuring receptacle.

' 'For instance`,'the radial scraper plates may be Adriven by a ratchet and pawl mechanism which vis actuated ,by the driving mechanism of thesuction head, which `removes therefrom the portion of material presented vby the measuring. receptacle. This suction head must. be brought -rod is placed on a support the present invention it is possible' to pass quite loosebacco from the sack-like supply vessel according MANUFACTURING CIGAR FILLERS l c Stelzen', Dresden, Ger- Universelle Cigaretten- J.

May 15, V1931 claims. (c1. isi-39) each timerv to the lled measuring receptacle so that it can remove the tobacco portion and then carry out a movement in order 'to deposit the portion at another place.

The disc on which the material is placed is preferably the slanting bottom portion surrounding a circular groove, whilst at the tobacco out-` let there is also provided a shaker rod or the likev which ensures the uniform ow of the tobacco over the appropriate ledge of the outlet. Here again the shaking movement can be derived from the movement of the suction head in that the Y which is drawn by a spring against a cam connected with the suction head.

In order to ensure tacle always removes that theA measuring recepan uniform 'amount of toto my copending application SerialNo, 415,295, the sack-like supply vessel is preferably provided with beating members which, position of the measuring receptacle is reached, strike the voutside of the fabric wall ofthe sup.- ply vessel. yThus the wall of tobacco `resting against the fabric wall of the container is driven towards the middle, so that above the measuringreceptacle which is in its lowest position, the supply of tobacco is in an uniform layer. Further ritis preferable to arrange for the beaters tovbe lactuated bythe downwardly moving measuring receptacle in order thus to produce the beater action at the right moment vby positive' means. .In this arrangement the beaters may consist of tongues attachedto bell crank levers, so that, when the measuring receptacle moves downwards, stops or thelike fitted thereto strike the free ends of the Ybell when the lowest y Aso on each occasion,

crank lever and thus causethe tongues to swing y n ing movement, which helps the tobaccov arriving above the layer in the vessel, to be driven par.- tially backby the blows of the beater outwardsv over the wall of the vessel. If, on the other' hand, only the central'part of the bottom of the -vessel `is -under suction, then there is formed here a core of tobacco which assumes a kind ofconical form and, as experience hasfshown, assists inthe to the action of suction layer of tobaccofrom'being I arrangementl of the rest of Vthe tobacco. It has Yaway portion 1,

been found that the particles of tobacco by means of the core in conjunction with the walls of the bottom of the vessel, under the blows of the shaker, are arranged in a denite manner controlled from the middle of the vessel and so remove "the tendency of the particles once fixed from springing out of the measuring receptacle. The result is that a constantly uniform yamount of tobacco is collected in uniform thickness in the measuring receptacle. Y l

The invention is illustrated in the annexed drawings, in whichz- Fig. 1 is a vertical longitudinal section.

Fig. 2 is a plan, and

Figs. 3 and 4 are detailed views.

In the funnel-shaped container 1 which is attached to the base plate 2, there is arranged a cylinder 3 which is attached to the axle 4. The latter is mounted in a bearing 5 which is attached to the base plate 2. On the axle 4 is vmounted a-ratchet wheel 6 with which a pawl 7 engages. The latter is mounted on a pivot 8 which'is attached to the lever 9. The latter is mounted on a collar on the bearing 5; the lever 9 ispivotally-connected at 9 with a link 10 the other -side of which is connected by a pin 11 to the disc V23 (for the sake of clarity the lever -9 is shown extended in Fig. l). To the cylinder 3 are attached triangular plates 12 which divide the funnel-shaped space into several equal parts, `in the present example into three parts. The funnel-shaped container 1 is formed with a cut Y the discharge edge :r of which is provided with a yrod 13. The latter isadapted to pivot about the pin 14 of the support 18, and under the inuenceof a spring 17 which tends to draw the rod 173 constantly towards a pin 16 in a slot 15 and fixed in the support 18. The latter is lpivotally mounted on a bolt-18ct, By the Youtward swinging movement of the suction fhead 20'towards the container 1,as indicated in full linesthe nger- 19 comes into contact with "27 is provided with the 4support 18 so that therodrlrcomes into Contact with thek tobacco frombelow and proinote's an uniform deposition of vthe tobacco. 'The'suction head is connected by a hollow arm 121 with an axle22n 4formed by a pipe or the like. On' this axle 22 there is also mounted a disc23 to which the pin 11 is attached. Y

,'fInthe container 24, by means of the ring 25, there'is secured a cloth 26,` the outer side -of which is attached to the measuring receptacle 27 va'ndser'vesas la collecting vessel (cf. U. S. Patent Serial No. 415,295). The measuring receptacle a perforated bottom 28 to which is Aconnected a suction piping consisting `of"a rubber pipe 29. rljhe vertically displaceable. Y rod '30 is provided.- with a spring wedge, provided in the bushing 31 of the'bearing 31", engages. ,The bushing 31 is turned to and fro by the crank'disc 31",. On 'the rod 30 there is mounted a sleeve 33Vwhich is provided with flanges in which a roller 34 of a rocker lever 35 engages. The rocker lever is v-rnounted'at 36 on the bracket 32 and is provided 'witha slot guide35. In this slot guide 35T there engagesa crank-pin 37;v `which is' provided with a-roller,-andwhich is mounted on a-crank disc 38. 'Ilhclatter is mounted onfa shaft 39 which lis Yconnected with. `a *driving mechanism not shown int-he drawings.

"in the receptacle Y27 and drawn towards" in known manner a periodical swinging movement to the axle 22.

At the right end position of the suction head 20 indicated by dotted lines in Figs. 1 and 2, is arranged a funnel 40, the mouth vof Vwhich is provided with a channel 41 `ol vU-shaped crosssection and bent into a semi-circle. Both sides of this channel 4l end in two downwardly di- Under each ofthe-members141" -there is arranged a pressure chamber 42 in which, by means of a plunger 43, the tobacco ller is formed, The channel 41 is providedv with a plate-45 which is mounted on an arm 46. VThe latter is mounted on an axle 47, which by means of `a cam 47' is swung periodically to and `fro in such manner that the tobacco which :passes through the funnel into `the 41 is fed alternately to the two pressure channels42 by the plate 45.

AThe apparatus operates manner.

The tobacco insertedfby hand,y conveyer belts or the like into the funnel-shaped container f1, is, by means of the plates or`wings12-which :are set into slow rotation by thelink 10 vand the pawl 7, passed towards-thecut-awayportion11 through which it .falls down onto the'eloth-26. The rod 13 Which'is swung up anddownibythe suction head 20, ensures that the tobacco VAiiows down uniformly Ythrough the outlet 1. supply of tobacco Vheld inthe cloth 26 is-correin the following spondingly.supplemented on its removalby-the Thus. the l also takes place during continuous turning to Y and fro the parts of tobacco of the receptacle are shaken downfand returned to the-supply of tobacco inthe cloth 26..;The suction action exerted on-thevreceptacle 27 by the suction piping Y29 ensuresv an easy anchoing of a suitable quantity of It should be noted that the suction action producedv by the pipe 29 isonly sullicient to ensure that `the tobacco'held in the receptacle is incompact and loose,-and`that the formationof lumps, which might easily prevent uniform separation, is prevented. f Y.

YAs already mentioned, the rotation of the plates 12 in the container 1` is so arranged that lying Y over the edge `tobacco threads l on all occasions only so much tobaccois deliv- Y ered to the cloth asis removedby-the suction head. By exact regulation of ,the f movement which is transmitted by the pawl 7 to the ratchet wheel 6, this can be done with a certain amount of accuracy. However, in order tov'keep the supply inthe cloth uniform in all casesjthecloth- 26 is provided with anr opening 26"Y through which in all cases the tobacco slides down over the slideway 49 into a collecting vessel 50, `whenV too much is delivered into the cloth 26 from the container l.

As soon as the measuring receptacle 27 arrives upper position (that is the-positionindi cated in'full lines -in Fig. l) the suction head 20 which is then in the position indicatedby dot- A the` perforated surface 20 of the suction head 20.

pressure action. Whilst the measuring receptacle 27 then moves downwards in order to be filled again, the suction head 20` is moved into the right-hand position indicated by Ydotted lines in Fig. l. vDuring this movement the suction head is passed yover' a rotating raking roller 44 which removes thev protruding threads of tobaccov from the suction head 20. Then the suction action of the suctionhead`20 is interruptedfsothat the tobacco can be passed throughthe funnel 40 into the channel 41. From the latter the tobacco, still `in loose condition,` passes into the ap propriate pressing channel 42.- Then the tobacco first comes into contact with an oscillating ap 48 which acts` uponthe individual tobacco strips in such manner: that they come into position substantiallyr transversely'to the Vlongitudinal direction of the pressure channely 42.

In` all the arrangements described above importance has been attached tothe fact that the tobacco is always in aloose and incompact condition. .Only upon arrivallin the pressure channel 42-itself is the portion of tobacco compressed into .a tobacco-filling. Y

Forthe'sake of convenience, as shown in Fig. 3, the sack-shaped supply container 26'may be provided with brackets 45on which bell crank levers 4'7 are pivoted at 46. Whereas one ,end of each bell crank lever extends beneath the boss 27 of the measuring receptacle 27, the other ends of the bell crank levers are provided with beaters in the form of tongues 48. .'When the measuring receptacle 27. moves downwards, the boss 27 of the measuring'receptacle i 27 comes into contact with the free ends of the bell crank levers 47, whereby the tongues 48 nxed thereto beat against the cloth wall 26. When the measuring receptacle moves upwards the bell crank leversrest against stops/49 which are provided on the brackets 45. In order to be Vable to adjust the amplitudeof the oscillation of the tongues 45?v and therefore their beating action, adjusting screws 49 are provided on the stops 49. By the beating of the tongues 48 against the cloth wall 26 the annular Wall of tobacco formed therein on lthe downward movement of the measuring receptacle is demolished.

In the form of construction shown in Figs. 1 and 2, the entire base ofthe measuring receptacle is perforated. It is, however, preferable to insert in the measuring receptacle 2'7-as shown in Fig. 4-a curved bottom`50, the central portion 50 of this being provided with an opening Vwhich is connected with a junction piece 51 for bacco from said supply container to said collector and means for compressing said tobacco removed from said collector into the shape of a ller.
