I This invention relates to hoppers for: cigae rette packaging machines, its principal objectsl'being to provide,'in' a hopper which feeds cigarettes throughpassageways to the packaging mechanism; improved means 1 for preventing the cigarettesi'romr becoming jammed .or;;misaligned-at the entrance of the passageways; and *means vit'or =prevent= ing cigarettes 1 from 'becoming ured; or

jamming, as a result of falling toorapidly to their ejecting position in the .lower ends of the passageways, A' hopper of thetype which this invention is designed'to improve, and the relation of sucha hopper to the compacter' and other parts of the cigarette packaging machine, is 'fully disclosed in Patent No. 1,608,l63, patented N ove nber 23, 19 26, to Wilhelm B. Bronander, to which referenceismade. 1 l .v

In the present I device, :-j amming or misalignment at the entrance of the cigarette passageways is prevented by pairs of oscillating rollers. Q'It has .been ioimd-that by oscillating the :rolle'r's; that is, rotating" them alternately in opposite directions, thesejro'llers will shake the cigarettes and -prevent them from sticking togethen'or entering fbetween the rollers two at atimeeor at an angle, as sometimes happens with rollers -opmttescespeciallyvwhen g reae 611 endwise;

' :An :arm 21 of this segment is connectedby a link 22'with a bell crank. lever 23 'fixedly same. The invention, therefore, is not to berestricted to the precise details of the structure shown and described. 7

In the device shown, a hopper body'lO is mounted on a base plate 11 supported by stands '12, lThehopper' bodycarries a'receptacle' l3 providing a source of supply of "cigarettes, whichv has aremovable front Wall-1ft and a} fixedrear wall 'l5.'-"A- hous v t v in ball bearings, knurled agitating rollers 17 extending intoand through the ,hopper ing "16 attached to, Hopper body 10 carries,

body. A; gear segment 18, mounted 0 11a shaft 19 supported in the housing 16, rocks spur, gears 20 mounted on the rollers 17.

mounted on shaft 24. An arm of the bell crank lever 23" carries a transverse pin, 26 bywhich it is coupled to a lever 27, which is looselyrnountedon the shaft 24: and is actuated by the camoperated rod-28. The

coupling. pin 26 is provided with a handle 29 and is held inengageinent with the lever ,27ineans ofa spring 30. (Fig; 1).. In

caselthe hopper feeding mechanism, should 7 7 temporarily fail, or the cigarettes in the hopper should become jammed'from any other cause and requirea quick shaking,the'

pin 26 can becreadily disengagedfrom lever 27 by: pulling handle '29, whereupon arm 25 can be actuated manually. c

; .Thefrollers 1!, supporting a: portionof the'supplyof cigarettes, are: so placed as to; form the lips of the mouths of the passage ways 8l-into whichlthe cigarettes are vto be 7 fed. 7 Adjacentfroller's "are spaced apart to permit on'ly" onecigarette at a time to pass t between--them. infrhe: passageways 31 are formed bypartitionplates 7 32 held in 'posi-' tion by the bracket andithe stop bars 34;

andi35 fastened to'the hopper body 10. The

The outwardly ben't plate 39 mounted on top of l door '36 By opening-the door 36, 'any accidentally w misplaced or: damaged' cigarette may be I "removed. w :1As-thel-cigarettes:are fed by the os'cillat- I ing rollers' intothei passageways 3l,- they V guides'the cigarettes intothe hopper body;

are, in each group of passageways, arrested and supported according to 'the time'in the cycle of themachineyeither by one of the ejecting p lungers lO, aswhen atthe' end of its forward stroke shown in dotted lines in'l F ig; 5, or by one of the projectingfingers' 412 inxits upposition, as when-the respective plunger is atrthe end ofiits return stroke showniinfl full lines sin'Fig; 5. :The fingers 41 which lower t e cigarettes rollers alternately move intoithe collecting chambers forming the lower portion of the passageways, are attached to the links 42 held by the-parallel 7 levers 43 andt l, which are cam operated 1 e by means. of therods 45, reciprocated by suitable cam andfcam follower means. The 7 fingers 41 'projectqtransversely into f the,

When'the cigarettes inone setofp'assageways have been lowered by the respective "finger 41, a group of cigarettes arranged to; form one package being then positioned inr u the respective collecting chambers, one of the'forked plungers l0 which are mounted for reciprocation on a bracket 47: held by a shaft' 48 sliding: inbearingst), traverses a set of passageways andejects the entire group through one of the guide compartments 50 attached to hopper .body lO into the previously mentioned compacter (not shown) in which it. is compacted intoapaok preliminary toifits advance into thev'wrapping mechanism; In the preferred-form,

in its retreat or backward movement," the plunger, having the cigarettesginthe ,pas-

sageways resting on it, stops for a moment after passing the finger 41,'thus providing ampletime' for movement to cigarette supporting position of the linger 41 while the cigarettes in the passageways are stillsup ported'by the plunger extending part way across the passageway. The plunger then completes its return stroke, clearing ,the passageway for the downward 'movement of theifinger, lowering the next group-of; ciga rettes intothe collecting chamber.
