To tf/ZZ whom it may concern;

Be it known than, EDWIN Bost wenn, a.

citizen of the United States, residing at Rich-1 mond, county of Henrico, and State of Vir y gioia, have invented-certain new and "useful:

Improvements in Cigarette iMachines, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

v This invention relates to delivery mechanism for cigarette-machines, and particularly rettes after the latter have left what is known as cigarette-rerolling mechanism, a mech-` anism for operating upon all-tobacco cigarettes afterthey have left the cigarette-formont their wrappers and removing wrinkles,

creases, and other irregularities therefrom.`

For this reason the improvements of the present invention are herein illustrated and will,

be'hereinafter particularly described in con- Junction with such a rerolling mechanism.

In the accompanyingdrawings, Figure 1 is a side elevation of a portion'ofa cigaretteforming mechanism and a cigarette-retelling mechanism provided with the improvementsv Fig. 2'

constituting the present invention. n is a detail in plan view of the rerolling mechanism and the mechanism embodying; the present invention. Fig. 3 is an end view' of the same looking toward the right of Fig.

11. Fig, 4 is aside elevation of the-same looking toward the left of Fig. 3. Fig. 5 is aseotion, on an enlarged scale, taken on the line '5 of Fig. 2. Fig. 6 is a similar View illustrat- 'is rolled,`and 4 the apron for rolling the cigarette. These parts are of familiar form and require no further description here, except'to state that in the position inl which the lparts are shown in Fig. 1 the apron 3 is shown as ready to receive a wrapper and tobacco to form a cigarette, while in Fig. 5 the cigarette is shown as formed with the apron in position to deliver it from the machine. From this cigarette-forming mechanism the cigarettes are delivered singlyvonto a pair of supporting-arms 5, whence they are delivered by'a pair of vibrating fingers 6 into the control of a cylinder 7 and curved support S, constituting the cigarette-rerolling mechanism, the

purpose of which, as before stated, is to reroll the cigarette and remove from the wrapper thereof all creases, wrinkles, and other irregularities. The fingers 6 are actuated and the cylinderf intermittently rotated from the driving shaft 2 through connections- Which will now he brieiiy described. For this purpose the lingers 6 are connected to a rock-shaft 9, jonrnaled in the frame 10 of the rerolling mechanism and provided with a downwardly-extending spring-pressed arm 11, connected by a pin-and-slot connection 'with one end of a link 12, the opposite end 'bar16, slidingina guide 17, journaled onv the shaft 14. The rack-bar 16 is connected bya pin and slot with one endo a lever 18, fulcrumed in the frame 1 of the cigarette-formlng mechanism andprovided with a bowl 19,

engaged by a cam 20 on the driving-shaft 2,

the cam 2O during part of its rotation moving the lever 18 and rack-bar 16 downwardly against the tension of a spring 2l, connected to the latter and to the frame 10, said spring after each downward` movement of said lever and rack-bar returning them to their normal or upper position. As the parts are shown in Fig. 1 the rerolling-cylinder is at rest. As the driving-shaft rotates in the direction of the arrow, Fig. 1, the cam 20, engaging the bowl 19 of the lever- 18, will depress the latter and the rack-bar 16 and through the gear 15 rotate the shaft 14, and thus through the crank-arm 13, link 12, and arm 1l move the TOO bearing the segmental gear 15.

fingers G from the position in which they are shown in Fig. 5 to the position in which they are shown in-Fig. 6, a cigarette during such movement of the fingers 6 being delivered to the rerolling mechanism. As the bowl 19 of the lever 18 leaves the high part of the cam 2O the spring 21 will draw the rack-bar 16 and lever 18 upwardly, the rack-bar 16 during such upward movement rotating the shaft 14 in the opposite direction. This movement of the shaft 14 will restore the crank-arm 13, link l2, and arm 1l from the position in which they are shown in Fig. 6 to the position in which they are shown in Fig. 5, thus returning the lingers 6 to position to receive another cigarette from the cigarette-forming mechanism.

As a cigarette is delivered from the forming mechanism it falls to the position shown by dotted lines in Fig. 5 in rear of a catcher 22, pivoted in the arms 5, and as the fingers 6 move the cigarette along the arms the cigarette swings the catcher 22 downwardly into the position shown in Fig. 6, the fingers 6 on their return movement engaging the rear end of the catcher and restoring it to normal position, as shown in Fig. 5.

The connections for intermittently rotating the rerolling-cylinder 7 will now be described. These connections consist of a disk or cam 23, fast to one end of the shaft 24 of the rerolling-cylinder and provided with a notch 25, engaged by a spring-pressed pawl 26, piv-` 28, journaled on the shaft 24, and which sleeve is provided with a pinion 29, connected by an intermediate 30 with a segmental gear 3l upon the end of the shaft 14 opposite that From these connections it results that as the rack-bar 16 is moved downwardly by the cam 20, as just described, for the purpose of moving the iingers 6 toward the rerolling mechanism to deliver a cigarette thereto the segmental gear 3l will through the intermediate 30 rotate the pinion 29 from left to right, Fig. 4, thus moving the pawl 26 away from the notch 25 in Athe disk 23, there being therefore no movement imparted to the rerolling-cylinder 7. The segmental gear 3l, intermediate 30, and pinion 29 are, as will be observed, so proportioned relatively one to the other that during thisdownward movement of the rackbar 16 the pinion 29 will make a complete revolution, thus again bringing the pivoted pawl 26 into engagement with the notch 25 of the disk 23. As the bowl 19 of the lever 18 leaves the high part of the cam 2O and the rack-bar 16 is then drawn upwardly by the spring 21 the shaft 14 will be rotated by the rack-bar in the opposite direction and the pinion 29 through the segmental gear 31 and intermediate 30 rotated from left to right, Fig. 4, and the pawl 2G thus through the disk 23 rotates the rerolling-cylinder 7 in a like direction or as indicated by the arrow in Fig. 1. This rotation of the cylinder 7 will continue during the upward movement of the rack-bar 16, the cylinder during such movement' of the rack-bar making a complete revolution.

To insu re the delivery ofthe cigarette from between the curved support or guide 8 and cylinder 7, the latter is provided with a longitudinal blade 32, which takes in behind the cigarette (see Figs. 5 and 6) and ejects it from the support 8. For the purpose of positively arresting the cylinder 7 after it has made a complete revolution it is provided with a notched disk or cam 33 upon the end of the shaft 24 opposite that provided with the notched disk or cam 23, the notch in the disk 33 being engaged by the short hooked arm of a lever 34, pivoted in the frame 10 and which is Aheld normally in position for engaging the notch in disk 33 by the weight of its longer arm, this lever being moved out of locking position by a bowl 35, carried by the rackbar 16 during the downward movement of the latter and maintained out of such locking position during the iirst part of the upward movement thereof and until rotation of cylinder 7 and shaft 24 has been begun and the disk 33 moved thereby out of position for engagement by the lever 34. As the shaft 24 completes a revolution the disk 33 is engaged by the lever 34 and rotation of said shaft and cylinder 7 thus positively arrested. vTo prevent rebound of the cylinder 7 when thus arrested and also to overcome any tendency it may have for any other reason to move rearwardly, a spring-brake 36 is provided, Figs. 2 3, bearing against the face of the cylinder. From the foregoing it will be observed that during the downward movement of the rackbar 16 the fingers 6 are moved from their cigarette-receiving position toward the rerolling-cylinder 7 to deliver a cigarette thereto, that during such downward movement of the rack-bar 16 the rerolling-cylinder 7 remains at rest, and that upon the upward movement of the rack-bar 16 under the stress of the spring 21 the fingers 6 are returned to receiving position and the rerolling-cylinder 1'0- tated in the direction ofthe arrow, Fig. 1, to reroll the cigarette delivered to it by said iingers 6. From this rerolling mechanism the cigarettes are delivered singly into the control of cutting devices for trimming the ends of the cigarettes. For this purpose the ma- IOO IIO

chine is provided with a trough 37, into which 10, which rock-shaft is provided with an arm 4l, connected through a link 42 with a crank- Y arm 43 upon the shaft 14, which, as before stated, is rotated iirst in one direction and then in the other by the sliding rack-bar 16.

The connections betweenV the shaft 14V andv cutters 38 are such that the movement of the vibrating cutters toward the stationary cut'- ters 39-that is, from the position in which they are shown in Fig. 5 to the position in which they are shown in Fig. 6--takes place during the upward movement of the rackbar 16, -this movement of the vibrating cutters 38 being simultaneous with the movement of the lingers 6 from their receiving position toward the rerolling mechanism. The

return movement of the vibrating cutters 38 likewise takes. place simultaneously with the return toreceiving position of the lingers 6.

In order to insure Vthe delivery of the trimmed cigarette from between the supports or shanks of the stationary cutters 39, where it is left by the vibrating cutters, it is necessary to provide means for positively engaging the side of the cigarette and moving it from between such Shanks or supports. Cigarettes, and particularly all-tobacco ciga-l rettes, immediately after beingoperated upon by the forming mechanism of a rerolling mechanism are very delicate and require very careful handling or manipulation in order to y avoid breakage ordistortion or other injury to the cigarette, and the mechanism provided for positively engaging and moving the cigarettes from between the shanks'or supports of the stationary cutters 39 must be of such character as to engage and move the cigarette in such way as to avoid all liability of such injury. Mechanism of this character'is pro- -vided by the present invention, which mechwhich is fulcrumed in the frame of the cigav rette-forming mechanism and which is providedwith a bowl'53, engaged by a cam 54v on the driving-shaft 2 of the machine. The

. lever 52 is moved positively up and down by the cam 54, and during its upward movement it moves the sliding rod 48 upwardly, thus throwing the `fingers 44 to their rearward position, as illustrated in Figs. l and 6 and in full lines in Fig. 5, and on its downward movement moves the ingers 44 in the oppo; site direction to the position in Which-they Aare shown by dotted lines in Fig. 5, the iingers 44 in moving to this latter position engaging the cigarette and moving it from between the shanks or supports of the stationary cutters 39. The cigarette thus moved by the fingers 44 is dropped onto a stationary inclined table 55, whence it is delivered into ani,7 convenient receptacle.

The cam 54 is so formed and so timed relatively to the movement of the vibrating cutters 38 that during the movement of said cutters from cigarette-receiving position toward the stationary cutters 39 the vibrating fingers 44 are retained by the cam 54 in their rearward position. l(Illustrated in Fig. l.) As soon as, or shortly after, the movement of the vibrating cutters 38 toward the stationary cutters 39 is completed the cam 54 will rock the lever 52 and the sliding rod 48'downwardly, thus 'moving the fingers 44 against'the cigarette lying between the supports or shanksof the stationary cutters 39. into the position shown by dotted lines in Fig. ,5. The fingers 44 move twice into ejecting position d nring the rotation of the cam 54, which is so formed, as shown in Fig. l, as to depress the lever 52, then raise the same, and then again depress it, so that the vibrating lingers 44 are thrown forward twice during each operation of the machine. The engagement of the cigarette by the tin gers 44 takes place just before or just as the vibrating cutters 38 start on their return movement away from the stationaryeutters 39, so as to prevent the Withdrawal of the cigarette by the cutters 38 from between the cuttersV 39. This is a feature of importance, as it prevents injury to or breakage of the cigarettes, which would result from their withdrawal by the cutters 38. yThe extent of movement of the fingers 44 also is such as to insure the ejection positively of the cigarettes singly from between the stationary cutters 39, land 4this also is a feature of importance, as unless the cigarettes be thus ejected they are liable'to stick-and accumulate between the cutters 39, in which case in order to remove them it is necessary for the attendant to do so by hand,'with the liability of injury from the vibrating cutters 38.

To insure the proper delivery of the cigarettes to the' trough 37 and vibrating cutters 38, a pair of guides v56 is provided on opposite sides of the trough, which engage the ends of the cigarette and move them endwse to center them. I
