[ In‘ such hoppers it is usual to provide some means for controlling the ?ow of the cigarettes I i from the body of the hopper to the discharge or 10 mouth whereby choking of the- mouth is pre vented and ‘it is an object of the invention to provide improved means for. this purpose. A ‘further object is to provide improved means for controlling the bulk‘ of the cigarettes in the 15‘ hopper while the predetermined number of ciga rettes' is 'being'removed'by pusher of the wrap (cram-5) j‘ _ ‘ ' . , 1 II which terminate at theirilower edges in an outlet, capable of delivering a predetermined, number of cigarettes,simultaneouslylin a horizon-' tal line. ‘The front'wall ‘is carried on brackets l3 by adjustable pivots _l‘_4 ‘and is held against ad-? 5'” justable stop pins *l'5_by:means' of springs l6. Located above the outletjand'adapted to‘ oscil late about a' horizontal‘vv axis is a gate element which is in the nature of "spaced superposed A elements or plates H and it", ‘The plates of the lower element I‘! are vtorined in onewith a mount ing-l9 by which the gate‘device is carried upon ‘an oscillable shaft 20. The ‘mounting l9 ex tends above the axis'of the‘shaft and is adapted to carry the upper A element l8 which is attached it: tothe mounting at the apex of‘ the A. ‘The angle between the plates‘ oii'vthei'uppern element 18, According to onefeature of'the‘ invention an may 'be'about:>100°"an‘d ‘the sides vor the A may‘ oscillating gate element or agitator is located terminate slightly below the axis of the shaft '20. 20" within the hopper above ‘the outlet therefrom These side plates‘may' 'be capable of extension‘ and is adapted to afford a two point control .of by adjustable end pieces 18a. so "that‘the space ping means. the ?ow of the cigarettes in the ‘hopper.

Further features of the invention will be here inafter described ‘and de?ned in the claims. In the accompanying‘ drawings: Figure 1 is a side view of the ‘hopper supply shown in ‘relation to the table of a packing ma chine. ‘ ‘ Figure 2 is'an end view of the hopper alone. 50? The arm 2! is *slotted so‘that the point of con; nection of the rod‘ '22'ift ‘eretomay be adjusted whereby the amplitude; “the osciilations of the gate element maybe varied: ' “I U" ' I _ ' In operation,v Yas'thef gate member l1,‘ I8 is o‘s-j‘ cillated the‘ ends of the plates“ I] or the lower,‘ A move'in paths'substa'ntially parallelto the sloping‘ walls l2 of the hopper 1while the ends of theplates, l8 of the upper A ‘will move in'substantially‘ 'ver-‘ ticalpathsf‘f‘ '‘ ‘ ’ “ ’ ' “ The upper A‘elem'ent l8‘support's the main body of cigarettes in! thehopper' ‘and causes them‘to‘ Figure 3 is a section on the line 3-301‘ Figure 1. flow outwardly 'towards the ends of the hopper, In carrying the invention into effect according while the oscillations of ‘such element will vcause a ?owing of cigarettes‘ intothe'spaces I25 be tween ‘the vA elements. The oscillations 'of‘ the lower A‘ element l'lzwi'llscause a ?ow of cigarettes into thespace 26 zbelowuthe lower A whereby an to ‘one convenient mode as applied to a ‘hopper feed for a cigarette packeting machine a hopper is provided comprising a ?xed rear wall [-0, an 55? adjustable front wall H and lower inclined ‘walls 40 2 2,124,187 adequate supply of cigarettes will be available for the outlet of the hopper without the possi bility of choking up the outlet owing to the weight of the cigarettes in the hopper. The A elements will thus provide a ?ow controlling device by is again actuated to permit the cam 33 to func tion. This however, is not intended to exclude other arrangements for oscillation of the chute vanes, in order to retard the ?ow of cigarettes, which which there will be a two stage or two point con may embody the basic idea of means herein trol of the ?ow on either side of the hopper en after claimed, which includes appropriate means by which the chute vane‘ ends can be oscillated bodily across the upper ends of the ?xed table vanes, simultaneously, to retard the flow of ciga 10 rettes for the stated purpose. suring the cigarettes ?owing down in ‘parallel formation without risk of crushingvof the ciga; 10 rettes as they pass the gate elements I8 and I1. Below the outlet from the hopper a chute 5D is provided which is formed of aseries of vanes 21 Located between the hopper opening and the to provide a series of parallel passages 28 ar chute an agitator device is provided comprising ranged vertically and of a length to contain each ‘ transverse bars or steps 4|], 4| mounted upon a 15 a number of cigarettes. ~ Conveniently there are ten passageways 28 .and the lowest cigarettes are adapted to rest upon a table or shelf 30 from which the desired number, say two rows, or twenty cigarettes are delivered 20 axially by pusher elements to the packeting bar‘-42~coinciding with the ?xed wall I0. The 15 bar 42 is connected to a reciprocable slide 43 which is provided with a roll 44 engaging a ro-i tary cam 45 on the cam shaft 25. A spring 46 holds the roll 44 up to the cam. By‘the provision of the agitator the flow of the 20 It will be appreciated that ‘in removing the cigarettes into the passageways of the chute is ensured. two lower rows a tilting of the cigarettes in the next upper or third row will occur which may. The sides of the passageways 28 in the chute are closed by strips 52 and 53 the latter being mechanism. . a . have the effect of disturbing the flow of the mounted as a block to pivot upon the bar 41 so 25 cigarettes down the passageways. ' that they may be lifted to getat the passage In order to avoid this disturbance it is desirable to stop the ?ow of cigarettes down the passage ways 28 while the lowest rows are being removed, and for this purpose a chute isv adapted to co operate with the vaned lower pasageways 29 formed of a height to take two cigarettes in each Ways should a stoppage occur or for any other passage. 7 V The vanes 28a forming the passageways 29 are ?xed to the table 30 upon which the lowest row of cigarettes is adapted to rest. ‘ reciprocate. horizontally, the amplitude of the reciprocation being about equal to one half the , _ v -_ ' o The side strips 52 are retained in position by springs 48. ' v 30 . It .will be appreciated that the rotation of the cam 33 will be synchronized with the pusher ele ment of the wrapper device so that the chute of the, hopper is moved to stop the ?ow of ciga rettes whilst the pusher operates to remove the 35 predetermined number of cigarettes from the . The table passageways 29 are permanently ?xed but the vaned chute 50 is mounted so that it can. pitch of the vanes. reason. I When the vanes 28 of the chute are moved out table passageways. It is to be noted that the improved agitating feed means and the improved mouth of chute constructions may be utilized independently of 40 one another. I claim: ‘ . of register with the vanes 28a of the table, the 1. A hopper’ for supplying cigarettes or like lowest cigarettes in the chute will rest upon the shaped articles to a packing machine, said ma chine having a packing table provided with ?xed, 45 45 vanes 28a. of the table and thus the ?ow of the cigarettes will be arrested during which period upright, compartment-forming vanes, said hopper the pusher will remove the cigarettes from the having a vaned chute provided with passageways pasageway 29 between the tablervanes 28a. _ through which the articles are delivered to cor It is convenient to arrange the vaned chute responding compartments on the packing table 50 separate from the body of the hopper and to said compartments being of a depth to contain a 50 hang it upon links 3| which are pivotally con predetermined number of articles, said chute nected to the framework 5| so that the desired being, mounted for lateral reciprocation to move reciprocation may be effected. The reciprocaq tion maybe obtained in any suitable way and 55 conveniently by connecting the chute to an arm 32 associated with the crank shaft 25 by which the gate device 11, I8 is oscillated such shaft hav ing a rotary cam 33 engaging a roller 34 on said arm so that the cam imparts a thrust to the 60 arm, the return movement being effected by a spring 35 or springs. The end of the arm is slotted and supported upon the crank shaft. The cam 33 may also at the same time be'adapted. to impart a vibratory movement to the suspended, 65 chute to assist the passage of‘ the. cigarettes through the chute. ‘ It may be necessary to arrest the supply of cigarettes to the plunger for adjustment pur poses or otherwise and forv this a manually oper 70 able cam 36 is provided adapted to be pivoted upon the shaft '25 by the handle 3'! with a posi-.; tion to engage a pin 38 on the bar 32 to impart a movement to the ‘chute. 7-5 1 The cam 36 has a the passageways out of register with said com partments and into register with the upper ends of said ‘?xed vanes, thereby to arrest the ?ow 55 of articles through the chute, while the articles are removed axially from said compartments. 2.
