42 Claims. (Ci. 1314109) y This invention is for improvernents` in or relating to apparatus forfeeding out tobacco, and
refers to apparatus of the .kind in which the out` tobacco is carried by an endless conveyor having tobacco-engaging teeth thereon.
In machines of the kind described it is `usual for the conveyor (e. g., a .carded conveyor) initially to feed more tobacco than is required and for this reason meansare employed for removing the surplus tobacco and for forming a substantially even Carpet of tobacco on the conveyor.

Again, aocordine'to the present inventionthere is provided apparatus ofthe kind referred to comprising 4in combination means to move the Conveyor forwardly While carrying tobacco which has vbeen agbstraoted'from a Supply, Separating devioeto separatesurplus tobacco from'fthe conveyor, said separating device having tobacco-enseeing teeth which are opposed tothegdirection of movement of thejonveyor and adjacentjthc teeth oi thefoonveyor, and means to cause during-operation@ the epparatosrelative move ment; (e, et, reiative reciorooeto'ry movement)v between the Conveyor 'end .thotteth ofthe seooretins 'device ino direction transverse to the tionvtheremevfbe provided presser means for :pressing tobacco into the'teethof the conveyor Whilst guiding it in its same general direction of movement in e path which diverges from'that of the conveyor.
Further according to the present invention tere is provided a method of-removing surplus tobacco from the endless oonveyorrby a separating device lhaving an uneven tobaooeengaging edge, comprising moving the conveyor forwardly Whilst having tobacco thereon, 'arranging the separating .devoe'so thattne edge is opposed to the direction of movement ofthe conveyor ata position adjacent the teeth thereof and causing the edge to give alat'eral movement to the fortlleedge to separate surplus tobacco; from -`the conveyor. Pressure may be applied to the tobacco onthe conveyor in the region cioseto the tobaoco-renseeing edge for the purpose of packing tobacco into the conveyor teeth and for holding the tobasco aga-inst the conveyor during 'separation of surplus tobacco, thus assistn,lr the `Separation of surplus tobacco. Preferably the separated tobasco is returned on to the conveyor at a position in advance of that where the said pressure applied. Y
.The invention also provides apparatus of the vkind referred to, wherein there is provided a separating devise having a tobacco-(engaging Edge lforwardrnovement ofthe conveyor, I In apparatus eooordinglto the present invenin the. region of the tobeoCo-eneegingedee. ,The

Y
l Preferably the separating device 'has teeth" wnioniare nof generally. rectangular shapehe tobacco-engaging edge'being constituted in 'suon to a portion of Figure 1 but illustrating a slight l modification.
Figure 2 is a side view of the apparatus shown in Figure 1. f
Figure 3 is an end view of the apparatus, partly in section, and looking in the direction of the arrow A in Figure 2.
Figure 4 is a detail in section of the tobacco# separating device shown in Figure 1, but slightly modified.
Figure 5 is a plan showing Va part of the t0- bacco-separating device and showing the shape of the tobacco-engaging, edge. l
Figure 6 is a sectional view of a modied construction embodying the invention. Y
Figures 7 and 8 are views taken from each end of the tobacco feeding apparatus shown in Figure 1 and show the. driving arrangements. y
Like reference numerals refer to like parts throughoutthe several figures of the drawings. Referring to Figure 1, the apparatus comprises a Vhopper yI at the bottom of which there is a smooth roller 2 having retractable pins 3 operating in .known manner. The conveyor roller 4 has tobacco-engaging teeth formed by'cards, the
the blade and having a curved, guide surface.
The separating device is located adjacent the teeth of the conveyor 4 and has-a tobaccoengaging edge 9 which isopposed to the direction of movement of the conveyor and which is adjacent the teeth of the conveyor 4 and arciently thinV to effect separation in a satisfactory manner.
The edge 9 is placed as close as possible to the tops of the teeth on the conveyor 4, although in practice a slight space is allowed between the edge 9 and the conveyor teeth to prevent fouling betweenthe edge and the conveyor teeth due to possible irregularities ofthe latter.
In the example described and shown in Figure 1, the teeth of the blade 6 are bent upwardly (as also shown by thechain line 690 in Figure 5), so that all parts of the tobacco-engaging edge 9 are at the same distance above the teeth of the conveyor 4.
The blade element 6 is reciprocated as de- VVscribed later, in a direction transverse to the Y g direction of movement of the surface of the conveyor. This lateral reciproc-ation of the saw edge assists in separating the surplus tobacco from tobacco between the conveyor teeth and also tends to cause an even distribution of the tobacco. YThis will be so, since surplus tobacco removed from one part of 'the conveyor can ranged to separate surplus tobacco from the conveyor.
Asfcan be seen more clearly from Figure 5, the tobacco-engaging edge 9 of the tobacco-separatingdevice is uneven and saw-like in profile, vthe blade element I5 being provided with teeth which y, are of generally rectangular shape and the tobacco-engaging edge is constituted by the free edges of the teeth (that is to say, the tops and sides of the teeth), as Well as the edges connecting the bases of adjacent teeth. The free edges of the teeth are chamfered as are also the edges connecting the bases of adjacent teeth. 'I'hus in effect the whole of the uneven edge 9 of the blade G constitutes a tobacco-engaging edge which as can be seen from the drawings is of substantial conveyor 4.
The edge itself although thin is not sharp, since a sharp edge would have the Vtendency to cut the tobacco unduly. An edge of about 0.4 millimetre to 0.8 millimetre is, however, suffiin this way be brushed by the teeth of the blade 6 to ll the conveyor teeth at portions which may have aV shortage of tobacco. The extent of this transverse movement will be a question of individual choice, but it will be obvious that the longer the stroke, within reason, the better will be the distributing effect.y In order to prevent tobacco being carried sideways off the conveyor, the back portion of the hopper I above the roller. 2 and to the right ofthe conveyor 4 (as seen in Figure 1) is made narrower than the roller 2 and the conveyor 4 so that the width ofthe conveyor isY greater than the width of the tobacco stream carried by it to the edge 9. After passing the edge, the tobacco stream is wider and -in the form of a carpet.
Surplus'tobacco which is not spread ordistributed as'aforesaid passes over theredge 9 so that it is removed/from the conveyor 4 by being deflected by the edge and the guide surface v8Y away from the conveyor whilst being guided l in its same Ygeneral direction o f movement in a path which diverges from that of the conveyor and is prevented from being Yfed past the edge.
Looatedrabove the tobacco-engaging edge 9 and slightly'to'the'right of it as shown in Figure l therefi'sjjprovided a presser element of light construction sok as to"apply a relatively lightpressu'rewto the tobacco on the conveyor '4 in the region `ofthe tobacco-engaging edge 9. The presser element II! tends to pack the tobacco in to the teeth'of the conveyor 4 and holds the tobacco during the separation of surplus tobacco from the surface cf the conveyor, thus assisting the separation.
The'presser element as can be seen in Figure 1 has, considered rin the direction of movement of the conveyor, a convexl tobacco-engaging surface, and is freely mounted to ride on the tobacco fed by the conveyor 4. This is effected by mounting the presser element I9 on armsrI I which are pivoted at I2, thus permitting the presser element Iii to oscillate about the centre I2. The presser element is of ovate section taken along a plane lying in the direction of movement of the conveyor. vThe presser element I0 constitutes one of the opposed walls of a passage, the other wall being constituted by the guide element 8. This presser element ID and the guide 8 form a diverging passage through which surplus tobacco iscaused to pass after ithas separated from the escapes is made" diverging in order to reduce anyltend'- encyf'f'orthe tobacco to form a choke vin the pas.
sage. Y The-sides m2 of thehopper form'the other `walls of the passage.` The frame IIJI carriesthe sides IGZ. y Y
VLocated abovethe passage there is provided a tamper element I3 which isarranged'to berecip- Vrocated vertically. The tamper I3 is suspended from an end Vof the lever I4Hby a chain I 5 '-The lever lll `is mounted on a shaft I6 which is operated mechanically to raise and-lower-the tamper I3. Above thepresser element and to the right of it there is provided ajroller II having'rearwardly inclined pins I8 toconstitute a returner means for removing tobacco away frornthecutlet of the passage, that is, tobacco emerging from between the bottom of theftamper I3 and the presser member ID and for depositorytobacco so removed uponthe surface ofthe conveyor 4; at -a position in advance of the"tobacco-engagingedge 9. As can be `seen in Figure 1 the Vdirection of rotation of the roller II is anti-clockwise. l
The function of the raking pins I8 is not Aonly to return tobacco to the surfaceof the conveyor,
Y but also to act as a rough trimming device for f the tobaccoA onthe conveyor 4 itself for the to'- bacco which hasbeen abstracted from Vthesupply Yin, thehoppenj The'raking teeth IB removellarge masses of tobacco which may be brought upl by the conveyor Il. The finer control is, howeven effected by the separating ,deviceA In the yexample depi'ctedinligure Yl jinj'the Adrawings. the returner'rneans comprises a'raking device. The upper 'and vruiter @surface of the presser, element is comprises' aguiding surface u i .vh'ich is interposed between the raking 'jdevice and the inletendof'the .passage and guides the 'tobaccoto be deposited bythe pins I8 to a positien in advance ofthe passage. It'will be appreciated that the inletend of the' passage is defined by the area lying'` betweenV the tobacco-engaging edge 9 cfthe separating device and thelower surfaceof'the presser 'element IB.'
instead of providing apresser element of ovate section such as the presser element "I l), the presser element may be of circular section and may be varranged tobe freelymounted about. its centre, as illustratedn Figurefla. The roller presser elementY could be `arranged to be pivotedl ina similar manner to Y the presser element Il?. A
roller is, however, not so good as the ovate vsection, since with a Yroller an accumulation of tobacco tends to form in front of the roller, Whereas 'the narrow end .of the ovate llls` the area in which tobacco would otherwise accumulate in front of a roller. Y
Y The Ymechanism for recprocatingthe blade 6 is shown in Figures 2 and 3. The blade 5 is connected by clamps IES to flexible straps IDII- fixedA c at 3S to curved faces of double armed levers 39 which are. pivoted at 4Q to bracketsl xedlto the hopper frames.

Inv this manner all the rollers are drivenin the directions shown at the appropriatespeeds.
Figure shows a modified construction in accordance with the present invention. The separating device as can becseen --from Figure 6 is the same as that shown in `Figure 1. Thetamping device I3 is similarlyarranged,tothat shown in Figure 1. In Figure 6, however, there is provided in front ofthe tobacco-engaging edge v9 a roller 2|0 which rotates in a clockwise direction so that the co-operating portions of the roller 4 and the roller 2|0 move Ain the same direction.
The teeth on the roller 2|8 are1not so close to.
gether as on the conveyor 4 and the roller 2|@ lgoes, at a slower peripheral speed than vthe conveyor 4. As in the case of the presserelement I in Figure 1, the roller2|0 helps to pack the tobacco into theteeth of the conveyor 4 `Aand .holds the tobacco during the separation of surplus tobacco, .thereby vassisting the `.separating action of the tobacco-engaging edge 9.
Surplus tobacco is positively removed from' the conveyor 4 by the roller lI8 and is taken upwardly through the passage between the surface of the guide 8 andv the roller 2|8, so that it is guidedjaway from Ythe conveyor in its' same general direction of movement in a path which diverges from that ofthe conveyor 4 whilst being positively fed by the ro1ler2|8. Tobacco carried by the roller 2|0 isV removed from the teeth of the latter` by a'raking device having rakes- |80 carried on an arm |8| whichis pivoted ata point |82. The rakes |80 are pivotally mounted on the arm |8| at a point |83, but are frictionallyi held against angular movement'on'the arm |8I.
A lever |84 is provided `on the mountingv for the rakes |88, anda chain |85 anchored tothe frame of the machine at |88 is connected as nected to the rakes |88 there is a cam |81 having a surface |88 which is adapted to engage a fixed stop |89 when the lever arm |8I, which is positively driven, 'is' in its uppermost position.
Also con-" cause the leverV |84 to turn in an anti-clockwise directionand thus further movement of the-lever .-|,8| wilLcause the ends of the rakes to move through-the path |92. At the end of the anticlockwise stroke the ends of the rakes |80 will be at point |93, and thus on the clockwise stroke .the ends of the rakes will follow a path |84 shown in dotted lines, `that path being an are struck from the centre |82. When, however, the lever |8| has moved suflicien'tly far in its clockwise stroke that the ends of the rakes |80 reach the point |95, the cam surface |88 will have engaged .the xed stop |89. Y Continued movement of the lever |8| in the clockwise direction Will cause the cam |81 and the rakes |80 to turn in alolockwise direction about .the centre |83, and thus the ends of the rakes will follow the path` |95 so that at the en d of the-clockwise stroke, the ends of the rakes ,will be in the position |91. They then move through the aforesaid path which is an arc struck from the point |82. In the anti-clockwise stroke the rakes remove tobacco from the teethfof the roller 2|0. Some of this removed tobacco. Will be returned to theY surface of the conveyor 4 and other tobacco will be taken by the rakes and returned into the hopper.
v,The rakes |80 moving along the path |90 are arranged to providea` rough trimming action for the tobacco on the conveyor 4, thene trimming as is also thecase in Figure 1 being effected by the separating device 5.
The tobacco after passingthe separating device p 5`may be fed in'thermanner shown in Figure l `or inany other convenient or desired manner. 35
Y Figure 6, ,a raking device such as is described in Instead of'using the raking devicel shown in British Patent specification No. 441,433 could be provided. The advantage, however, 0f the con- Y struction shown in'Figure 6 is that on the clockwise stroke ofthe rake the ends of the rakes are removed to a distance from the surface of the conveyor 4 so that they have no action whatsoever on the tobacco on'the clockwise stroke.
