34Claims.
This invention relates to an improvement in scrap bunch cigar machines, its main object being the production of a machine specially adapted for large scrap tobacco, the machine herein described consisting of a stationary magazine or hopper with intermittently revolving agitators, an oscillating transfer drum with a reciprocating tobacco pan, a measuring chamber having gates which open automatically to admit the tobacco delivered by the pan, a chargecompressing and measuring unit with automatic knock-cut device, a charge-cutting and transfer unit, and a charge-rolling and ejecting unit. With this and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations hereinafter fully described and then specifically set forth in the claims hereunto appended.
The scrap tobacco is placed in the hopper in which it is kept in loose condition by intermittently revolving agitators. Below the outlet of the hopper is placed an oscillating transfer drum in which a slidable pan is supported on a camoperated arm. In each cycle of the machine, this drum makes one-half revolution and returns to starting position. While in the starting position, the pan ascends into the hopper and returns with a quantity of tobacco, the cam-operated knives provided on the pan being open during the ascent, and closing on reaching its uppermost position to separate the quantity of the tobacco in the pan from the mass of tobacco in the hopper. Upon the return of the pan, the transfer drum with the filled pan makes its forward half-turn during which the knives on the pan are opened by engagement with a stationary cam so that the charge can drop into the measuring chamber below, the cam-operated gates of the latter opening during the forward turn of the drum. While the drum, with the knives on the pan still open, then returns to starting position, the gates of the measuring chamber are closed and the freshly deposited loose charge is compressed by a horizontally slidable spring-tensioned plunger to the proper density determined by the adjustment of the plunger spring. The pan is designed to hold slightly more tobacco than is required for one cigar bunch, so that there is a surplus of tobacco present in the measuring chamber after the charge has been severed. When this surplus to-' bacco has accumulated in sufficient quantity for another cigar bunch, the motion of the transfer drum is'automaticaliy stopped for one cycle of the machine by means of linkage between the compressing plunger and a cam which operates the oscillating means of the transfer arm. This linkage requires a. predetermined minimum forward stroke of the plunger to actuate the said cam; when the surplus tobacco accumulated in the measuring chamber prevents the plunger from reaching the end of its predetermined stroke, the transfer drum cam remains stationary and no more tobacco is delivered to the measuring chamber during that cycle of the machine. A charge of tobacco sufiicient for one cigar bunch is severed by a cam-operated vertically reciprocating knife and is then carried downward by a vertically reciprocating transfer plunger which finally expels it. Upon the return of the transfer plunger and the charge cutting knife, a rolling pin adjustably carried by a swinging rolling arm rolls the charge into a binder previously deposited on the apron and delivers it into a holder at the end of the rolling table from which it is taken by an operator serving a nearby bunchshaping and wrapper-applying machine.

In carrying the invention into effect there is provided a hopper for holding a supply of scrap tobacco, a measuring chamber below the hopper, an oscillating transfer drum, a pan in said drum adapted to be projected into the hopper to receive a quantity of tobacco and retracted into the drum with aid quantity. mechanism foroecillatingsaiddrumand actuating'saidpan to remove a quantity of tobacco from said hopper and deliver it to the measuring chamber. means for compressing the tobacco in said measuring chamber, means for rolling a charge of tobacco-- in a bunch binder, means for cutting of! a charge from the tobacco in the measuring chamber and delivering it to said rolling means. and means controlled by the tobacco-compressing meansfor incapacitating said mechanism if there is a quantity of tobacco sufficient for more than two bunch charges in the measuring chamber, and there after rehabilitating said mechanism. In the best constructions contemplated the pan is provided mechanism, and a cam piece connected to said lever for disengaging the pawl means. These various means and parts may be widely varied in construction within the scope of the claims, for the particular machine selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific construction shown and described.
Referring now to Figs. 1 and 2, the side frames ll, ii of the machine support a base or table II upon which are mounted pedestals l1, II, a support block ll and a pedestal frame It. In the side frames II is journaled the drive shaft 20 of the machine which is driven through a worm wheel reduction gearing 24 on a shaft 22 by a belt 23 from a motor 24. The shaft II carries cams 2|, II and 21. The side frames II, in conjunction with a bearing 28 suspended from the base it. supports a shaft 2! on which the cam levers actuated by the cams II, 20 and 21 are fulcrumed.
The pedestals l1, l1 support the hopper II and carry a shaft ii on which the horizontal transfer drum 3! is fixed. The support block ll carries the measuring chamber 33 and the slide bar 34 for the charge-compressing plunger fl.
and on the pedestal frame I! is mounted the chamber 36, forming a continuation of the meas-' uring chamber, and charge-cutting and vertical transfer plunger unit 31. To the-base It is attached the rolling table it over which swings the rolling pin it which is adjustably carried by an arm 40 pivoted on a shaft ll supported by the side frames IS. A treadie II on a shaft 43 in .frames II, by means of an arm l4. connecting rod 4i and bell-crank lever 40, controls the main clutch of the machine on shaft 22. s
The tobacco T in hopper 3. is kept in loose condition by agitating rods ll mounted in ablock 48 on a shaft 49 supported by the hopper. the
shaft It being intermittently driven from shaft II by means of sprockets II andll and chain '2, the sprocket II being attached to shaft II by a suitable device, such as a ball clutch or a pawl and ratchet, not shown, was to turn in one direction only. The shaft II is alternately turned one-half revolution forward and back by means of a gear I! engaging with a rack attached to a cam lever 85 pivoted on shaft 20 and engaging cam "by means of roller It. Fast on shaft Ii cases is the hubof the-drum II spider ll turnably mounted pedestal l'i' animal's-commas estal II and eattending through a semi-circular slot ll infl tlie" head of drum 8!. within the drum carries a forked bracket Ii supporting a shaft "Jigs. 4 and}.
To shaft flare-attached the sideerms of th pan it whichis slidable in an in th drum I}, thegsides of this opening being provided withpackingsllandtl. Thepantlhasa pocket provided therein adapted to receive a quantity of tobacco when the pan is projected into the hopper, The cover plates It, which are fixed on the top of the pan. prevent tobacco on either side of .thepocket, from entering the space provided for the travel of the knives l8. Pivoted on shaft II are arms l'l carrying the knives ll for separating the quantity of tobacco in the pocket from the mass in the hopper, the arms 81 being normally held closed-by a spring is connecting the same. Each of the arms I! has a link ll pivoted to a pin H carrying a roller 12 adapted to engage with a cam piece II on bracket I. In a slot of one of the side arms of scoop II is pivoted a double lever ll tensioned by a leaf spring ll, one arm of which lever engages with pin II when its other arm is arrested by a stop screw II in a lug on one of the arms of splder ll. The shaft I. has a crank 11, Fig. 1, connected by arod ll to a cam lever ll fulcrumed on shaft fl and carrying a roller ll engaging with a track of cam II.
In the starting position of drum 3!, when the pan I in the drum is underneath the hopper outlet, the cam lever it controls the crank 'll. thereby projecting the pan it into the hopper ll. As the pan reaches its uppermost position in the hopper, the trip lever 14 is turned by e aging with stop screws It, so that its trip arm rates the pin Ii and moves the links from ing of the scoop, the roller 12 engages with the cam piece II which is so shaped that the pin II is thereby moved towards the center of the drum to a point beyond the neutral position of the links ll, thus opening the knives as shown In dotted lines in Fig. l, the spring 69 then holding them open during the return of the drum to starting position.
In the dotted position referred to, the quantity of tobacco T carried by the pan is dropped into the measiu'ing chamber It. the hinged gates 82 of which havebeen raised during the transfer motionofthe pan by a connecting rod 83 attached to can lever II, the said connecting rod moving oneendof a double lever 04 fulcrumed in a-bearing bracket I fastened to a cross-piece 8! on slide; bar N, the other end of lever 84 being connected by a link I! to a slide ll guided by a bar-ll attached by a cross bar 9. to slide bar- 34, the slide ll having links ll pivoted to the gate l2. (Bee Figs. 1, 2, 6 and 7.)
The loose quantity of tobacco T deposited by the pan into the measuring chamber 33, which is supported by the cross piece It and by the ledger plate "attached to frame It, is compressed into the chamber 33. which forms a continuation of the measuring chamber, by the plunger 33. The latter is attached to a rod 33 sliding in a lug 34 of slide 33 mounted on slide bar 34. A spring 33 on rod 33 bears against the end of plunger 33 and is adjusted to the proper tension by a socket 31 adiustably attached to a rod 33 carried by lug 34, the tension of spring 33 regulating the density of the tobacco compressed by the plunger 33. The slide 33 is connecteli by a link 33 to a cam lever I43 fulcrumed on shaft 23 and having a roller III in engagement with cam 21. With the above construction for projecting the pan into the hopper and cutting off the quantity of tobacco in its pocket, there is no tendency for the tobacco to bridge over the hopper outlet and thus retard the delivery of the tobacco from the hopper, as in prior scrap tobacco feeds. Furthermore, any excessively large scraps projecting out from the pocket will be severed, and therefore will not impede the turning of the transfer drum in its housing.
In order to prevent scant charging of the cutting chamber in case the pan should fail to pick up a full charge, the feed is so arranged that there will always be a surplus of tobacco in the measuring chamber. For this purpose, the pocket in pan 33 is made to hold an excess of tobacco over one bunch charge, and the stroke of the plunger 33 is adjusted to such a clearance from the chamber 33 as to require at least two bunch charges of the proper density to fill said chamber and the clearance space. Thus, after the charge in the chamber 33 has been severed, there is still more than enough compressed tobacco T" left in the measuring chamber to again fill the cutting chamber. Therefore, even when the next quantity of tobacco delivered by the pan happens to be scanty, there will be a full bunch charge. If, on the other hand, the quantitles delivered are each in excess of a bunch charge, this surplus tobacco will accumulate in the measuring chamber and from time to time will prevent the plunger 35 from reaching the end of its predetermined stroke. At these times, a finger I32 attached to the end of rod 33 will fail to engage the trip lever I33 placed in its path, and thus will stop the feed drum and scoop from operating during the next cycle of the machine so that then one charge from the pan is omitted and the measuring chamber cleared from excessive tobacco accumulation.
The trip lever I33, Figs. 6 and 'I, is carried by a stud I44 in support block I3 on which it is held in engagement with a crank arm I33 by a spring I34. The arm I33 is connected by a cross-stud I31 and a rod I33 to one end of a horizontal double lever I33, Figs. 1 and 2,-the other end of which is held in engagementwith the end of a vertical double lever III by means of springs III and H2. The levers I33 and III are iulcrumed on studs H3 and H4. respectively, in side frame II. The free end of lever I I3 carrles a cam piece IIi having an upper and slower cam surface adapted to engage with the driving mechanism of cam 23 which controls the motion of the feed drum rack 34 and of the pan-lever shaft 33. The cam 23 is keyed on a sleeve Iii which rides loosely on shaft 23 and has an arm II1 carrying'a pawl II3 engaging with ratchet II3 fasiaon shaft 23, the pawl III being held in engageinent by a spring I23. The tooth end of pawl II3 carries a roller HI, and to the face of ratchet H3 is pivoted a roller I22, both rollplates I33 and depress the ,slides I34.
ers being in vertical alignment with the cam piece III.
The cam piece III is normally in the path of roller III. When the plunger 33 travels its full stroke, the finger I32 engages with the lever I33 and thereby trips the lever I33, allowing the spring III to turn the lever III and thus to bring the cam piece III out of registration with the path of roller I2I. The engagement of pawl I II with ratchet II3 then will not be disturbed, and the cam 23 will be driven by the ratchet I I3. accumulated in the measuring chamber shortens the stroke of plunger 33 so that the finger III2 will not engage with lever I33, the cam piece III will remain in its raised position and will cause the roller I2I to engage with it, thereby lifting the pawl III out of mesh with the ratchet II3, thus releasing the cam 23 and stopping the tobacco feed. Then when the finger I32 engages with lever I33, on full stroke of plunger 33, and trips the lever I33, the spring II2 turns lever III to bring the cam piece out of engagement with the roller I2I and restart the tobacco feed. In the-tripped position of lever I III, on full stroke of plunger 33, the cam piece H5 comes into registering position with roller I22 so that the turning of ratchet III will engage the roller with the cam piece and reset the lever IIII into tripping position against the end of the lever I33 for the next stroke of the plunger.
When the chamber 33 has been filled by the advance of plunger 33, the reciprocating vertical rod I23 descends, thereby operating the charge-cutting knife I24 and the charge ejecting or transfer plunger 31. The rod I23 which slides in bearings of the pedestal frame I3, is actuated by a cam lever I25 fulcrumed on shaft 23 and having a roller I26 in a track of cam 21.
To the slide rod I23, Figs. 8 to 12, is clamped a bracket I21 the free end of which projects into an opening of a block I23 attached to slides I23 and is amxed thereto by a vertical pin I3Il. The slides I23 which are connected by a tie plate I3I carry the charge-cutting knife I24, the vertical position of which is adjusted by screws I32 held in block 23. The slides I23 fit into a recess of frame I3 in which they are guided by retaining strips I33. Into a recess of the knife slides I23 are fitted plunger slides I34 joined by a tie plate I35, and in the space between the slides I34, the knife I24 and the tie plate I35, slides the vertical charge ejecting plunger 31. Into slots provided in the latter project studs I33 carried by block I23 and engaging with pins I31 resting on coil springs I33 inserted into vertical holes formed in the body of the plunger 31.
To the tops of slides I34 are attached plates I33 resting on coil springs I43 held on blocks "I, attached to knife slides I23. In the upposition of rod I23, the springs I40 hold the plates I33 against studs I42 held in frame I3. To the tops of the knife slides I23 are fastened plates I43 carrying adjustable set screws I44 which on the down-stroke of rod I23 engage the The plunger 31, in a top strip I43 attached to it, carries an adjusting screw I43 which rests on one arm of a bell-crank lever I41 pivoted on bracket I21 attached to rod I23. The other arm of lever I41 carries a cam roller I43 engaging with a stationary cam piece I43 attached to frame I3.
To the bottom of the slide tie plate I3! is fastened the back of the chamber 33 in the sides of which, formed by the ends of slides I34, is

the chamber, Pi attached to slide To lugs of frame it is fastened the ledger plate I! for the knife I24. The ledger plate, which is horizontally adjustable by screws I. is hollowed out to receive the delivery end of the measuring chamber II.
As the rod III descends, upon a charge having been delivered to the chamber I. the bracket I21 depresses the block III, thereby actuating the charge-cutting knife ill. During the descent of the knife, the plunger 11 is held in place by the springs I", the studs I80 depressing the pins lll against the tension ofthe springs ill, thereby gradually compressing the charge in the vertical direction while the same is being out. As soon as the charge is severed. the set screws I come into engagement with the plates ill, thereby depressing the plunger 11 and cutting chamber 36 against the premure of springs lllLthus transferring the charge to the rollins apron below.
tion, thereby turning lever in upon which rests I the stop screw I of the plunger. The latter is then free to move downward in the slides I34 due tothe stored-up tension of the springs Ill, and thus to expel the charge from the chamber 30.
On the return stroke of rod Ill, the springs I, released by the ascent of the screws-l, raise the plunger fl, chamber 30 and knife I24 until engagement of the plates I with the studs I42 takes place, whereupon the plunger and chamber ll 'are arrested and the knife ascends alone, the accompanying ascent of the studs I" then permitting the' pins Ill to rise, releasing the tension of the springs I. On the upward stroke of the slides 134, the cranks ill engage with the stops I53, thereby closing the gate I" so that the chamber 36 is now ready to receive a new charge.
The bunch charge B, Fig. 1,'-delivered by the plunger 31 onto the rolling apron I" is rolled by the rolling pin 39 into a binder laid on the apron by an operator, thereby forming the bunch B which at the end of the rolling pin stroke is delivered into a holder or clip I". The apron I" is fastened to the forward end of table I. by a strip I" and is held in proper tension by an apron-tightener arm I" which is pivoted on shaft 20 and actuated through a connecting rod in, a cam lever III and a roller Iii 'by cam 26. The portion of the apron "ion which the binder is laid. and the corresponding portion of table 38 which is hollow, are perforated and the table I8 is supplied with suction, from suitable means of well known construction not shown, which keeps the binder flat on the apron until it is rolled.
The rolling pin 39, Figs. 1. 2 and 3, is mounted in blocks I82 carried by a yoke I" pivoted in a swingable bracket I which in turn is pivoted to the rolling arm 40. By this arrangement, the angle of the rolling pin I! can be readily adiusted for rolling straight as wellas tapered bunches of various shapes.
