. 7 21 th t. {01. 1319) This invention relates'to combined scrap bunch forming and shaping machines, its main object being to provide novel means for automatically removing a cover from one of the bunchshapw ,5 ing pockets of a cigar bunch shaping. machine and serving itwith a cigar bunch simultaneously from the rolling table of a scrap bunch forming machine, thereby combining them into a'single self-contained piece of apparatus. With these .1 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 hereuntofiappended.

'With two independently operated separate machines for bunch forming and bunch shaping, it is necessary to transfer the rolled bunch by hand from the rolling table ofthe bunch machine into one of the pockets of the bunch shap- 2 ing turret,,which operation is often-performed unsatisfactorily by even an experiencedoperator. The novel cover removing and bunch transferring means'hereinafter described, not only dispenses withthis service of .an operator, but

;, locates the bunch properly .in the bunch shaping pocketso that better shaped cigars result from'its use. i

.This novel means consists in the. combination of a pairoi vertically swinging transfer arms which receive the bunch from the rolling table and carry it into position for further-.manipu lation; of a pair of 'locators which close upfon 7 I in construction within the scope of the claims,

the. bunch when in manipulating position and properly position the same in the transfer arms 5 and point up the ends of the sa1ne;,of aliiter which raises the located bunch; and ofv a horizontally swinging head having two arms and pivoted on a vertically reciprocating shaft which 4 receives the bunch in a pocket in, the bottom of tion with :a bunch shaping pocket in the turret, lowers it ,to the latter, and expels 'it into the pocket,, while a cam-operated slide in the other 5 arin engages the co er of said pocket, locks the same to the arm, raises it and swings it out of the way of the incoming bunch, tobe returned into position and unlocked as the first arm swings back into bunch receiving position. L

In the best forms of construction contemplated, said means includes a head havinga pair of arms,inea ns on one arm for receiving the bunch means-on' the otherarm for. engaging: the cover}: and means for lifting,

turning, and lowering said head All the above mentionedrneans and parts may be widely varied for the particular; machine selected to illustrate the invention isbut one of many possible concreteembodiments of the same. The invention,

tion of these arms is to receive the newly rolled bunch from the rolling table of thebunch shaping machine and to carry it' into position for insertion into pocket provided for this purpose in the bottomof the bunch carrying arm, hereinafter described. The bunchlrec'eiving ends of the arms 15 have a solid jaw, 18 and aresilient jaw 19 which is" pressed by a spring 20 against an adjustable set screw 21 in the'integral jaw so that the 'openinglof the empty jaws can be adjusted to the proper distance, somewhat smaller than the diameter of the bunch.

Vertical rods 22, guided in bearings 23 and 24 of pedestal 11 and actuated by a connecting bracket 25, a link 26 and a lever 2'7'from another cam not shown, operate the bunch lifter 28 which consists of a base secured to the upper ends of the rods 22 and carrying on bent arms a central and two outer blocks concaved to fit the shape of the bunch and designed for removing the latter from the transfer arms 15.

On horizontal rods 29 supported in a block 30 carried by a post 31 of pedestal 11 slide the locators 32, the bunch positioning ends of which have tapered depressions so as to shape or point up the ends of the bunch when closing up on the same. The locators 32 have inward projections 33 against which the jaws 19 of arms 15 rest in their bunch delivery position and which serve as guides for the bunch when raised by the lifter from the transfer arms. The locators 32 have horizontally projecting pins 34 through which they are actuated by levers 35 pivoted on studs 36 of pedestal 11, the levers 35 being connected by a bar 37 and actuated by a rod 38 pivoted to a stud 39 on an arm 40 of one of them. The rod 38 is operated from a cam, not shown.

In bearings 41 and 42 of frame 12 is slidably but non-turnably supported a vertical shaft 43 on which is loosely mounted a head 44 carrying two arms 45 and 46 at right angles to one another. The collar 47 fixed on shaft 43 normally rests on the bearing 41. When in this position, another fixed collar 48, having a tapered cam projection 49 extending radially from it in the direction of turret 81, rests on the head 44 which is supported in its lowermost position by one of two set screws 50, 50 carried in radial projections 51 of head 44 and resting on a horizontal projection of a guide bar 52 inserted in the bearing frame 12, see Figs. 1, 4, and 5. Thus, when the shaft 43 is raised by the rod 53 actuated from a cam, not shown, and pivotally attached to shaft 43 by means of socket joints 54 and 55 connected by a stud 56, it will first lift the collar 48 from the head 44 and then, after the collar 47 has come into contact with the bottom of head 44, will raise the head with its arms 45 and 46.

In radially projecting lugs 57, the head 44 carries a vertical rod 58'with which engages a forked block 59 turnably carried by one arm of a bell-crank lever 60 pivoted on a stud61 in bearing frame 12 and held in place by a collar 62. The other arm 63 of lever 60 is connected by a stud 64 to a rod 65 actuated by a cam, not shown. By moving the lever 60 from one position to the other, the fork 59 turns the head 44 through 90 degrees, thereby moving the arm 45 into the position formerly occupied by arm 46 andvice versa. In order to effect accurate registration of these arms with the bunch locator and with the turret mold respectively, the projections 51 of the head 44 are equipped with adjustable rollers 66 which in the extreme horizontal positions of the head 44 engage with one or the other side of bar 52 and guide the head in its vertical movement. The rollers 66 are fastened to the head by means of eccentric studs 6'7 so that the horizontal throw of the head can be accurately adjusted. All the cams used for producing the various movements of the transfer mechanism are driven in synchronism with the bunch forming and shaping machines, the drives of which are inter-connected.

The arm 45 at its bottom carries a pocket 68, formed by slightly spaced walls having concave cavities, for the reception of the bunch which is forced thereinto from the locators 32 by'the lifter 28 and retained therein by frictional cohesion and the pressure of said walls. On its top, the arm 45 has a boss 69 in which are guided two vertical pins 70 joined at their upper ends by a yoke 71 held in its Lip-position by a spring 72. On yoke 71 rests a roller '73 carried by one arm of a bell crank lever '74 pivoted on a stud 75 in lugs 76 of head 44. The other arm of lever '74 carries a roller '77 adapted to engage with the tapered cam projection 49 of collar 48 when arm 45 is in the bunch delivery position shown in Fig. 5. When this engagement takes place on the descent of shaft 43 relative to head 44, while the latter is supported by the set screw 50, the lever '74 is turned into position 74", Fig. 2, and the roller 73 depresses yoke 71 into position 71", thereby causing the pins 70 to eject the bunch from pocket 68.

The arm 46 at its bottom has two lugs 78 provided with transverse channels, Fig. 1, adapted to engage rollers 79 provided. at the ends of each mold cover 80 on the intermittently rotating bunch shaping turret 81 as each cover reaches its uppermost position. The details of the turret and indexing device 'for intermittently'rotating the turret are shown in the copending application of Rupert E. Rundell, Ser. No. 185,199, filed April 20, 1927, to which reference is made for a complete disclosure of the same. Each cover has two axially grooved radial upward projections 83, Figs. 1 and 4, and the arm 46 has a longitudinal slide 84 with two aligned downward projections 35 and 85' adapted to be engaged with the axial grooves in projections 83 by the action of a coil spring 86 stretched from a post 87 in arm 46 to a post 88 in slide 84. In the lowermost position of shaft 43, the slide 84 is kept out of engagement with cover 80 by a lever 89 pivoted on stud 90 in lugs 91 of head 44 and held in position by a roller 92 engaging with the tapered cam projection 49 or" collar 48 when arm 45 is in the bunch receiving position shown in Fig. 4. When disengagement of roller 92 and tapered cam projection 49 takes place on the ascent of shaft 43 relative to head 44, the spring 85 thus released causes the slide 84 to move into its engagement position 84 and thereby to lock cover 80 to arm 46, as shown in Fig. 5 and in dotted lines in Fig. 1.

The operation of the device is as follows:

Whenthe turret rotates, the shaft 43 is in its lowermost position with the set screw 50 of head 44 resting on guide bar 52 and the arms 45 and 46 in their receiving positions as shown in Fig. 4, the roller 66 being in contact with guide bar 52. Upward motion of rod 17 then causes the arms 15 to swing into their delivery position '15, shown in Figs. 1 and 2, in which the bunch B, which has previously been deposited into their jaws by. the chianti belt 93 as the latter had reached its end position on rolling table 94 by the motion of rolling pin 95, registers with the locators 32. As the chianti belt, rolling table,

and rolling pins are parts of a scrap bunchforming mechanism of well known construction, further description of the same is unnecessary. The locators are then moved toward the bunch into the dotted position 32'shown in Fig. 2, by the action of rod 38, thus pointing up the ends of the bunch and positioning it for proper entrance into pocket 68 of arm 45, into which the bunch is now inserted by the motion of lever 27 raising the lifter 28. While the lifter rests in its up-position, the rod 53 begins its upward 15o 'tive,positions 71 and 74'.

Having inserted most mold pocket of the turret mold, the carrier.

motion, the carrier shaft 43 'first'ascendlngalone,

releasingroller 92, which in the bunch receiving position of. the arms is in engagement with v cam projection 49, and thereby locking the cover mostposition'43' of thejshaft being in posi ,tion 48, Figs, land 2. The arm 45by this motion of rod 53jhas reached the position 45,; Fig.

2 with yoke Il a'nd'lever '74 in unchanged rela- During the ascent for head 44, the bunch lifter 28 descends and the 'locators 32 move apart into their original posi- 91 55 v V V Next, the rods 1'7 and are actuated, theforrner returningarms 15 into their bunch receiving position at the rolling table "94, and the latter swing the arms 45 and 46' from the position "shown in Fig. 4 to that shown in Fig. 5. With the arms in the latter position in which roller 166 contacts with bar 52, the rod 53 descends, first lowering shaft 43 and the arms'so that arm '45 .now is in delivery position above the open 'pocket of the turret moldSO, Fig. 5, and then, whenithe set screw 50" has come to rest on guide bar '52, lowering shaft 43 alone so thatthe tapered cam projection 49 of collar 48, which in the delivery position of the head registers with arm 45, turns the lever "74 into position 74",Fig. 2, thereby depressing the yoke 71 into position 71? and ejecting the bunch from the pocket 68 in the mold 80. The descent of the shaft 43 does not afiect the roller 92 because the arm 46 in this position of head 44 does not register with taper 49. i

the bunch B into the uppershaft 43 again ascends, first alone, lifting collar [48 from head 44, whereby the lever '74 is released and the ejecting pins 70 are raised by spring '72, and then, when the collar 47 has engaged head 44,'with the arms 45' and 46. When in uppermost position, clear of the covers of the closed mold pockets, the arm 45 is swung back into bunchreceiving position and the shaft 43 islowered. This brings cover 80, which during the insertion of the bunch B into the pocket of turret 81 was held out of the way by arm 46, back into position on the turret, the final downward movement of the shaft '43 returning the. taper 49 into engagement with the roller 92, thereby unlocking the coverfrom the arm. ,This final movementof shaft 43 has no effect on lever 74 'on arm 45 because roller 77 in'the bunch delivery position of the arms is degrees away from taper 49.

While the cover is replaced over the bunch B just inserted into the turret, the rolling pin which, during the inward movement of arms 15 and during the operation of the locators 32 and lifter 28, has been at rest at the far end of rolling table 34 to allow a new charge to be measured in the scrap bunch machine and deposited onto the chianti belt 93, and which during the transfer movement of the arms has rolled this charge intoa bunch, ejects the new bunch into the jaws of arms l5iand returns into resting position at the far end of the rolling table.

The replaced mold cover being held in place by means, not shown, incorporated with theturret, the latter is now ready to index forth'e lo- ,cating of theinext bunch shaping pocket.
