p This invention relatesl-to the'umethodofh controlling thefeed-of cigarette tobaccoin cigarette making machines. I

A featureof my inventionis the provision of suitable: steps for feedingcigarettetobacco I to theci'garette paper, which is sup 'lled 'andw fed pursuant tothe usual practice" y means of a tube belt or thelike in the formation of what is known as a cigarette'rod,lwhereby the feed of the tobacco effects the production a of cigarettes which'average the predeter mined weight ofit obacco content required by law or" in conformity 1 to anyudesiredweight 1 v i of hopper provided with asuitable form of of tobaccocontent. i 1

In*'the practice heretoforeharried-out g V Y 1s fed to an' apron indefinite quantities "of this and. foreign countries, the cigarette to= bacco'fed into the hopper is cardedbyone iormore sets of suitable" carding rolls "or like mechanisin 'and the feardedtobacco is deliv ered continuously to onesor r'norei'aprons for delivery; to the endlessfstrip of; cigarette 1 pa- 7 per, driven, by frictionalvcontactonasocalled tube belt at a" selected speed, where after the tube 'belt, *cigarette papenand tobacco are passed through a'so called -former or forming shoe toroll the cigarette paper and thereby roll cigarette tobacco while the resulting overlapping edge of the ciga-V rette paper is supplied withtsuitable jadhesive, thus forming thejcigarette rod,which cigarette rod is cut by a suitablesevering device into the individual cigarettes.- By such procedure, the weight of the carded cigarette tobacco varies from time to time, owing to' variations in the weight of thetobacco fed into the mechanism, and "owing also "to the i differences in weight or specificgravity of the e leaf,stem and other parts of the tobacco, and

further owing to i variations of weight or specific'gravity of different grades of tobacco in the usual blended charges; further variations arise 'owing' to the iformation of air pockets within the tobaccocharge and other: interruptions in feeding the tobacco charge to the carding device. i

It has also been proposedto deli ver into other conta'inerthe tax stampis applied;

seekto attain a uniform delivery to the card Z i ing devicegofthe tobacco charge within the;

hopper ;"however, such procedureis eflec-ted" by the "use ofmore or less cumbersomemachinery for intermittently charging the to- 'baccowithin the hopper, and theresults are i depen'd'ent upon factors "of variation of weight or specific gravity of-the various conf stituent parts-and notwithstanding produce variation in the average weight of the formed cigarettes; a v r a 'TPursuant to my invention, theci arette tobacco is fed intoany form of suitab e type carding mechanism and the carded;tob acco predetermined weight and the carded 'toi "bacco is delivered continuously from such apronto the cigarette paper in-continuous amount of substantially constant predeter mined weight, wherebfyft'he resulting" to bacco content perunit'leng'th of the cigarette rod'is of substantially constant weight and substantially uniform: weight of tobacco.

carton, 'box or' other container for the cigarettes when packed, to which carton,box or itliewresulting; individual cigarettes possess -I The uniform'weight isselected to correspond": to the desired total weightof tobacco in thfe' Pursuant to the most preferred form of i my invention, the carded cigarette tobacco is 'fed to the pan of a scale'or equivalent weighing v device, which-is set to tip at a predetermined weightyand'the' contents of"the-pan are deposited'upon the apron, which is progressedeat a uniformpredetermined speed,

the pan'of the scale being again filled and its contents likewise deposited in predetermined r time relationto the preceding lot dumped on 1 the apron, such weighing and dumping being continued successively. The pan of the scale" is preferablyiof greater length than its'width andthe efl'eetive rolls of the" carding mocha- 'nism" are of'a length corresponding to the:

the hopper and thus to the carding mecha hopper at-a predetermined level, to thereby length of the pan, whereby the carded to bacco is delivere'd into thepan to form a mass havingits length'greater than its width cor-" 'respondingjto thel'ength and width of the] pan, and also resulting in" each deposit of 7 quantity 7 "Furt er features and objects of the invenspective, an assembly'of any suitable hopper tion will be more fully understood from the following detail description and the accompap ying drawings, in which i 1g. 1 isa diagrammaticview,showing in central vertical section and partly, in peri provided with a suitable carding mechanism,

a weighing scale, and an apron and appurtenant devices for feeding the carded tobacco tq'an indefinite length of cigarette paper,

pursuantto my invention;

Fi 2 is a side elevation of theho per zr z P ing scale and appurtenant devices illustrated in Fig. 1; the view in Fig. 2 is taken onthe side ofthe hopper opposite to that of a 'F' 1; and r 13. 3 is a sectional elevation on line Refining to the drawings, and particularly to Figs. 1 andv 2, the hopper may be of suitable form and provided with a suit-.

ab set of oardi 'dev1ccs,-such as the card ing rolllil with w ich coacts the pin roll 12; the direction of rotation of the carding roll 11 is indicated by the arrow 13 and the dirootionof the pin roll 12' in the opposite direction, as shown by the arrow 14. The roll licence as a feeding roll, andis rotated in the direction indicated by the arrow 16. The

' 11:11:17 isany suitable type of agitating roll.

The shaft of the carding roll 11 is indicated at; 18 and is suitably mounted in bearings at its opposite ends'in the opposite side walls of 4 the p trated. The shaft of the pin roll 12 1s indiper 10, one wall 19 only being illuscated at 20. The shaft of the feeding roll is indicatedat 21 and the shaft'of the agitating roll'17 at 22, both of which shafts are similarly rotatively mounted at their respective op osite-ends'in the hopper 10.

The EOTPPB! 10 is otherwise of any suitable arrangement, such as the provision of the i as belt 23 serving as the effective bottom of the hopper 10 and mounted on and driven by suitable pulleys 24, 25 in the direction of the arrow 26 to move the upper and efiective length of the belt 23 in the direction of the snow. 27- nd thereby feed the charge 28 of cigarette tobacco to the carding roll 11. The bottom plate 29, preferablyof. concave form on its face which is directed toward the carding roll 11, is disposed in close adjacency therewith, to-prevent any dropping of the V r V C fit'ttQtbbacco ag-v at all times the desired uniform elements 1 corresponding tobacco from the hopper prior to being carded by the carding mechanism. 7

The pin roll 12 when in its operative position relative to the carding roll 11 effects in the usual manner the delivery of the carded tobacco fromthe carding mechanism, indicated bythe stream 30, and the paddle wheel 31 disposed pursuant to the usual practice toaet upon the-stream of carded tobacco.

However, pursuant to my invention, the

shaft 20 of the pin roll 12 is displaceable to movelthe pinr'oll 12 into and out of operative relation with the carding roll 11 testtain the oh' ctshereinafter more fully set forth and t us efiect the formation and interruption of the stream 30 of the carded tobacco. 1

Upon being carded,the ei ette ammo is weighed as by means of a am scale, the

a pan of which is indicated at 32 and the adjustable'weight at 33. Preferably, the pan 32 is of multiple compartment form, such as of threecompartments indicated respectively 323 32", 32": the pan 32 may be mounted on oppositely disposed studs 34 respectively projectin and bearin in suitable recesses in they'o ie 35 of the cam 36 of the scale.

The recesses of the yoke 35am indicated at 37 and in the instance are preferably trial gular of equal sides, the bottom side, one 37' being substantially horizontal and the lateral faces at each end of the stud 34 "form similarly equilateral triangles, the sides of the equilateral triangle being disposedv to locate the respective compartments 32, 32", 32 vertical i. e. reoeiving'position respectively. At one .sideof the yoke 35., I provide the tripped member 38, secured to the stud 34 at that side, the tripped member 38 comprising in number to the number of the compartments 32', 32", 32', in

thisinstance three. I provide the tripping member 39 mounted on a suitable shaft 40.

will be noted that the disposition of the de posits on the apron 46 at an angle to the direction of travelof the apron 46 facilitates the equalization of distribution of the contents of the spaced deposits on the roll 65 and averages up anyivariations of specific gravity of the tobaccoowing: to the. presence of relativelyheavyleaflor of stems or thelike.

, For the pur' oseof controllingthe depositions-ofrlots o substantially uni'form weight; 7 of carded tobacco on theapron 46 or equiv- It Will be noted that} therespective dea1ent, I provide suitable means for effecting the flow 30 of carded tobacco into acompartmentiof thepa'n'32 of the scale 31 and to in- 'terrupt suchstream 30 at the instant of filling cally controlled parts including the contact 1 70 insulatingly carried by t e am 36 of the scale, which contact is connected to the conductor 71 to one terminal of the battery72 or other suitable source of electrical energy, the

other terminal of the battery 72 being connected by the conductor 73 to the terminal 74 of the coil of the solenoid 75, the opposite ter- I minal 76 of which is connected by the conductor 77 to the contact 78 co-operating with the upon the de-energi'zation of the coil of the aforesaid contact 70.

The contact 78 is mounted on a suitable supoither of insulating material or electri @cally insulatedby means of suitable insulation; I have indicated the bracket 79 which" is mounted on and extends above the base 80 of the scale 31 as one form of support for the contact 78. 1

The stop 79 for the beam 36 of the scale is preferably adjustable to thereby regulate the spacing between the contacts 70, 78, when a compartment of the pan 32 is atthe stage of being filled. Upon each compartment being filled to the amount regulated by the weight 33, the beam 36 of the scale istilted on the contact 70 is moved into contact with the fixed contact 78, thereby closing the circuit through the source 72 and energizing the coil of the solenoid 75,'and thereby throwing the pin wheel12 from its position'of operativeness relative to the carding roll 11 to a ition of non-operation. I

e gears 41, 43 ma be suitably rotatably mounted at the ends 0 their respective shafts in oppositely disposed, vertically extendinng standards 7 9 (one only being shown.) 'secu toabase79.

As. one suitable form of mounting for the pin wheel 12, its shaft 20 of the pin whcel12 is secured to one end ofthe angular arm 81. The arm 81 is freely mounted intermediate its length on an end of the shaft 82 of the ulle 82, to provide pivotal movement of the, arm 1, and the opposite end of" the arm 81 is providedwith an opening for receiving the free end of the guide rod 83, thefixed end 84 of which guide rod 83 is pivotally secured to the side wall 19 of the hopper 10. The expensive spring 85 is coiled about its guide rod 83,to bias the arm 81 to move'the shaft 20 of the pin wheel 12 toward the carding roll 11. The stop 86 servesto limit the throw of the arm 81 under action of its spring 85.

The idler pulley 82 is driven by the belt 87 driven by the pulley 88 fixed on the shaft 180! the carding roll 11, and the pulley 89 fixed onthe shaft 31' of the paddle wheel 81 is driven'by the belt 90 from the pulley 82, and similarly the belt 91 driven from the pulby 88 drives the pulley 92 fixed on the shaft 20 of the pin wheel 12. The driving of the belts 90, 91 is preferably by meaneof sets of doubled pulleys respectively securedto one another, to provide a single belt for each pulley of the respective sets. The movement 0 the arm 81 and therewith the movement of the wheel 12 late nono erative relation with its carding roll 11 is efiected by the solenoid 75 when excited'by electrical current as above described by an suitable means, such as the core 93 of the so enoid 75 being pivotally conv nected to the arm 81 as at the location 94.

"The return of the pin wheel 12 to its operative position, and a similar movement of the paddle wheel 31, as above indicated, ensues solenoid 7 5 upon the breaking of the circuit by the contact 70 on the scale beam 36 being moved from engagement with the contact 78 when the tobacco contents of a filled compartr' ment of the scalepan 32 has been deposited upon the apron 46 and actuated by the spring 85. as above stated.

Thecarrying outof'my invention will be understood from the foregoing. It will be perceived, however, that upon excitatiou of the solenoid 7'5. arising u on the closure of the electrical circuit by t e tipping of the scale beam 36 when a compartment of the scale beam pan 32has been filled. A short interval drops into the compartment, including its asa sage past the paddle wheel 31, thereby ad ing 1 to the content'of the compartment of the scale pan 3? beyond the weight determined by the" setting of scale weight33. and such additional weight is compensated by setting the scale weight 33 toti the scale beam 36 at a position correspo'n ingly less than the predeter-' mined content by weight for the respective deposits of carded tobacco on the "apron 46.

It will be observed that the interval of time required to fill a compartment is less than the interval of time between the instants of tripping of the tripped member 38.

. Itwill be understood that the apparatus above described may be varied in arrangement as will appear clearly to those skilled in the art upon understanding my invention. Preferably, the apparatus affords the continuous operation of the carding mechanism notwithstanding the interruption of the stream of carded'tobacco and thereby maintain the carding mechanism in primed conditionto effect the restoration of the stream of cardedtobacco to the weighing device sub stantiully instantly upon the pin wheel or equivalent element being resorted to its operative position. The apparatus also preferably provides for relatively increased number of deposits perlength of the apron or equivas lent and correspondingly relatively decreased spacing betweenthe deposits on the apron.

Whereas, I have described my invention by refercnce to specific forms thereof, it will be f understood that many changes andmodific ations may be made Without departing from the spirit of the invention.
