Referring to, the drawing, ISA. indicates' the frame of a cigar machine supporting a table l l: to which a rolling table l2 is operatively connected. A channelV frame member I3 'and another member Hlf securely hold a tobaccoV feed mechanism, indicated. glehelally ai l5 and ld, in. Place above the. cigar irrathne.. A hopper 6. is .Supported bythe frame. l1 above the feed mechanism, and

pered chute I8 (Fig. 2) to direct the shredded tobacco into a measuring chamber 32 of the type shown in Reissue Patent No. 20,334, granted April 20, 1937, to F. C. Gladeck et al. In the process of feeding from the supply contained in the hopper I6, the shreds or pieces of tobacco are separated from the mass and fed to chute I8 in a shower through the medium of a carding belt I9 trained over pulleys 28 and 2|, mounted on shafts 22 and 23, respectively. The shaft 23 is driven by chain 24 which derives its motion from sprocket 25 fixed to cam shaft 26 journaled in bearings (not shown) in the cigar machine frame I 0.

A feed chute 21 is pivotally secured to the frame member I1 at 28 and is automatically operated through a pin and slot connection at 29 to a link 38 in order to permit the tobacco to enter between the walls 3| of the measuring chamber 32, provided with a door 32a which is automatically opened at the proper time to allow n a charge of tobacco advanced from the hopper to befed into themeasuring chamber.

The door 32a is mounted upon a shaft 35a to which is xed lever 35 connected at 34 to a link 33, which link is also connected to a cam lever-36 at 36a. Lever 36 has mounted thereon a cam follower 31 which engages with a cam 38 mounted on shaft 26 as viewed in Fig. 1.

It will be observed, therefore, that cam 38 causes link 33 to operate door 32a through rotationof vice, which is constructed according to the disclosure in the Gladeck et al. patent above referred to, is provided with a compressor plunger 32h, which, operating in the compression chamber as described in said patent, is mounted on a rod 32e slidably mounted in a block 32d slidable on guides 32g. A spring placed around rod 32e bears against the plunger B2b, and also against the spring'tension block 32e adjustably attached to rod 32j Vcarried by block 32d. Attached to the free end of rod 32c is a nger 32h in which is adjustably mounted a threaded adjusting member 327' which is positioned to engage finger 49|) which controls the feeding of the tobacco. Tobacco is fed from the chamber 32 by plunger 32h into a charge forming device C which in the illustrated embodiment is of the type shown in the Gladeck et al. patent, and is held therein by gate I2b. At the proper period in the machine cycle, knife |2a cuts off a charge of tobacco. The gate I2b is then swung downward, as shown in-dotted lines in Fig. 1 and the charge is ejected by the plunger of the forming device onto the 40 from a motor (not shown) runs continuouslyv to drive pulley 4I fixed to a shaft 42-by a belt 43, and through pulleys 44, 45 and 45, and the belts 41 and 48, similar to the driving mechanism disclosed inPatent 1,563,334, above mentioned, to actuate a picker roller 50 which picks the tobacco from belt I9 and directs it downwardly into chute I8. A bevel gear 49 on the shaft 42 meshes with a bevel gear 49a xed to a shaft 44a which carries the pulley 44 and drives the pulley 45. A clutch 5I of conventional design can be provided for starting and stopping the machine.

As stated previously, the belt I9 advances tobacco from the hopper into chute I8. In order to feed tobacco at the appropriate time, means are provided for imparting feeding movement to the belt when tobacco is needed in the compression chamber and for preventing its movement at all other times. Referring to Figs. 1, 3 and 4 it will be observed that clutch mechanism 52 controls the movement of the belt I9.

As described above, a chute 21 is pivotally mounted at 28 on the upright frame of the machine, and has connected thereto an adjustable link 38 pivotally secured to a block 38a fastened to shaft 63. A spring 21a secured to chute 21 and frame I4 normally holds the chute 21 against the chute I8 as shown in Fig. 1. When shaft B3 is rocked in a counterclockwise direction the chute 21 will discharge its contents into chamber v,32. Clamped upon the shaft 63 is a lever 62 to `3|) which are pivotally secured at 81 and 84, respectively, two links 85 and |82. Link 86 is also connected to a cam lever 88 which is pivoted at 89 to the machine frame and is provided with a cam .follower 90 engaging a cam 38h on shaft 25. A spring 88a secured to the lever 88 and to the frame (notshcwn) holds the cam follower 90 against cam 38h.

In order to vary the feeding period of belt I9, cam 381), which controls the rocking movement Li'oof lever 9| and hence pawl 54, is formed in two relatively movable parts 38a and 38C, one loosely and the other xedly mounted on shift 26. These parts are adjustably held together by means of screws 92 passed through slots 92a 4gformed in one of the cams, and secured in the other as shown in Figs. 1 and 5. Counterclockwise movement of lever 62 effects a discharge of chute 21 into chamber 32, as before mentioned.

Mounted upon a shaft B9 is a pawl 54 positioned to co-act with the teeth of a ratchet |98 forming a part of clutch 52 described hereinafter. Also fixed to shaft is a lever 5| which extends y downward and ccacts with a rounded or cam 55 portion 54a of a lever |54 loosely mounted on shaft 63. The prime function of lever 6| is to prevent reengagement of the clutch parts and prevent movement of the feeding belt I9 until the feed of additional tobacco from the hopper I6 is necessary for the formation of proper cigars. Lever 6I is held in this position by means of cam portion 64a of lever B4 (see Fig. l) Also secured to shaft 68 is a lever 9| to which is pivoted at 94 the other end of link |92 previously 55 mentioned. This end of the link is provided with a slot 95 in order to give the necessary lost motion connection required for the feed control mechanism. A spring 54a connected to one en d of lever 9| at 54o, and also to the hopper at 54e 70 normally tends to hold pawl 54 against ratchet I 88. The movement of lever 62, through the described connections plays an important part in feeding of tobacco, inasmuch as the clockwise movement thereof effected by slotted link |82 engaging with pin 94 on lever 9| detaches the pawl from `the iteeth .of ratchet T00 against the .tension of-spring 54ato .reengage the clutch and reins'titute the .movement of :belt 19. In 'order Ito insure the .stoppage of 'the .feed conveyor- 'the cam surface v614er.cooperating with .arm El Yhas been provided, fas :explained above.

'The rotation of .shaft 23 to foperate :feed belt t9 is effected by .means of sprocket'chain 24 and-clutch `mechanism 52.' In Figs. 3 and 4 this mechanism lis :shown 'in detail and consists t can be seen, therefore, vthat the rotation ofV shaft 23 `ceases whenever pawl' 54 bears against the teeth of ratchet Hill. This engagement causes v'the projections of ratchet m0 to force pins@ into 'their 'recesses' in y*driven member 16, .and move rollers orV ballsY 'Il from contact with the flange of driving member 56. This disengagement of 'clutch parts is 4accomplished every time arm 6l bears against cam portion Marci lever `E4, vand'also at least once each cycle when 'the lower'end o'f slot '95 of link .m2 lifts lever '91 -throughpin 94, and swings thepawl 54 into coaction with a vtoo'th'of lthe ratchet. A handwheel '3 is fixed to shaft 23 `to enable the machine 'to .be 'turned over manually. 1

'A latch mechanism is provided 'for controlling the movement .of cam surface 64a. 4In the illustrated embodiment the rocks'haft Gwhich' supports finger 43h has secured theretoi a lever '51 having a. 'free lend 'provided with a nose'l. 'At its other end the lever is connected at 68 vto an adjustable link 615, which link .in turnis connected at 66 to an end of lever 64. Nose T0 of lever 61 is adapted to bear `againstlever 'H whenever the tobacco feed is incapacitated, and whenever 'more 'tobacco is to be fed the nose4 is moved l.along the lever arm'll a into engagement With .la 'reduced ornotchedportion.r A link 13 is pivotally connected to an end' of lever 1I which is mounted on shaft '12.A The other end of this link 'is connected at 81a to a lever swingable on a pin 82 .on the .sideframe of themachine and provide'd with a cam .follower 85 which 'trains on a cam 83 and through that medium lifts Athe lever 81` and hence .swings the lever FH once during .each vrevolution of cam 83. In this manner arm Ha of lever 'H -is' swung at least once each cycle of the machine away from nose 16. A pin 1lb is located inthe 'path of movement of nose 1.0 and limits its'lfre'e upward movement under the urging of a spring 14 secured to lever G'Iat 68, and to the frame at '15. A spring 13a secured to lever 'll tends to hold lever arm 'Ha in contact with nose 1:0;

` The feed `mechanism .15a is operated by means of a sprocket 99 fixed to shaft 123 and provided with a chain engaging with a sprocket 99h on shaft 105. A pulley Illia cooperates with pulley la@ in supporting carded belt it] in operative position. 'Chain 99a trained over sprockets SSI) and .mi is responsible for the drive of belt 15a, power being supplied froml shaft 23 which mounts sprocket IIJ-I.

In the operation of the machine, tobacco'is nient with notch v'll/cl. of lever 1l.

fed periodically `from hopper 16 by means of carded belt 1w zinto. chute l-:8 and. is subsequently discharged iin-to the. .compression chamber 32. As. described' herein-above, shaft 26 which is continuously rotating, carries the adjustable cam 38h made `up fof two 'relatively .movable parts. When the lever '83k is raised, due -to engagement of follower 9U with the high :portion of cam 3819, pawl .54..ismove'd into engagement with the teeth ofratchet l the rotation of shaft 23, and the :accompanying movement of kfeeding fbelt t9 ceases. Whenzthe .vfollower imV rides off the high portion ofthe scam, lever 9| iis `moved in the clockwise 4'.-irc-:cti'on and `fpaiwl .54 is pulled from its engagement `with the .ratchet |90 and the normali drive `of shaft. 23` .is reinsti'tuted. Normaily, thepositi'o'ns of the cam members 38a and .rac .are :so adjusted :that 'somewhat more than an amountnecessary for one cigar bunch will be fed to the feed chute t8.. It can be seen therefore that under .these vconditions there will be a .gradual accumulation of tobacco in the compression chamber so that .at certain cycles of vthe. machine it will be unnecessary to feed additional tobacco to the feed chute I8. ln order to prevent this feed when no tobacco is needed in the compression chamber, means have been provided for accomplishing this purpose. This control Aassumes the form of the above described camssurface 64a which holds the arm 6l in the position `shown in Fig. 1, with pawl 54 bearing against the ratchet regardless of the position. vof lever 9L When 'additional'A tobacco is to be fed andv before th'e normal disabling mechanism yoperated by cam 38h can become effective, itis. necessary to move cam surface 64a from engagement lwith arm '6I. This is yaccomplished by means of adjusting .screw 32:1' carried by the plunger control mechanism which engages linger 49h mounted on' shaft 'B9' and rocks lever 61 clockwise away .from its engage- This movement disen'gages :arm Si 'from cam .surface 64a and makes it possible for vcani 38h to 'perform its prescribed functions, above mentioned. Upon return "of the plunger 32h to the position shown in Fig. 1., the :spring'll moves nose T0 up into engagement with aV pin Hb and moves the cam surface 64a up into position for re-engag'ement with arm el. The above 'described movement of nose i0 into engagement with pin Hb takes place :as a result of the counterclockwise movement of lever arm lla, which releases the connection between the nose 'Hl and the notched portion-of the lever arm lia. In 'the rotation 'of cam shaft 26, cam 83 engages with cam follower 85 once foreach revolution 'of shaft 8S and accomplishes the desired 'counterclockwise movement of lever *H against the tension of spring i3. The latch mechanism is then set for feedingV additional tobacco by reason of the fact that on the forward )movement of plunger 32h, screw 327 willengage trip finger 4817, :cause shaft 69 to rock, and nose 'lil'wili move downwardly along the notched varm portion ibof lever H whereupon carn 'surface '64a moves away from the tail of lever '61 and nose 10, either engages with the notch on lever arm "lla -or travels downwardly along the notched portion depending upon the adjustment of link 55. `Lever Blf is then free to move relative to l'cam surface '64a and link 86 can pull pawl 54 out of engagement with ratchet 100 so that clutch 52 is thrown into operationA and belt 'i9 conveys tobacco from the hopper into receptacle I8.
