Definitions

  • the present invention relates to an improvement in timing mechanisms of stem cutters or creasers for tobaccostemming machines.
  • the present invention provides a feeler' or measurer, for measuring the length of leaves, of improved design and of an entirely 'different type which eliminates many difficulties of a practical nature experienced inthe' operation of known machines.
  • the device therefore utilizes the tension of the leaves being-pulled through the machine and any loose leaves or scrap tobacco which may be carried along witha charge of the leaves, but are not gripped by the grippers, will not afiect its operation.

  • 1 and 2 are the cooperating grippers which are mounted on. the u ual chains 81 and82 and which grip the butt ends of the tobacco leaves.
  • 3 is the knife blade which is fastened to shaft 4 by suitable arms 5.
  • This shaft 4 revolves intermittently in ri'gidbearings (not shown) and is driven by a'sprocket wheel 'Z-thrOugh an adjustable coupling com posed of'a dial wheel 8, Figs. 2 and 3, sl'i'tb ably mounted on shaft 4 andkey'ed thereto by key 9.
  • Dial wheel 8 meshes with its coupling 10 which is fastened to sprocket 7 and is normally held iii-engagement therewith by spring 11 and washer 12.
  • the knife blade 3 cuts the tobacco stems against a' oller 13 both of which have the same length and extend across the machine.
  • Chain 14 connects sprocket wheels 7 and 15, the latter being fastened-to a cam 16, F 8, which is free to turn on shaft 17.
  • the sprocket 'wheel 15 is'keyed to cam 16 by a key 18 and cam 16' is provided with a bushing 19.
  • v A stud20 is fastened cam 16, Figs)? and 8, and carries a pawl 21 which by meansof a spring 23 is forced to engage the teeth of a ratchet wheel 22 when the knife is to be set in motion.
  • the pawl 21 and the ratchet wheel 22 are not engaged the pawl is held by a hook at pivoted on the stud 25.
  • pawl 21 The earlier or later release of pawl 21 by hook 24 will cause the pawl 21 to engage different teeth of ratchet wheel 22' and thereby time the knife motion earlier or later relato the face of the tive to the grippers 1 and 2.
  • the lifting of the hook 24, Fig. 1, is controlled by a segment 29 secured to the shaft 30 which is pivoted in suitable bearings, not shown. Normally the segment 29 is maintained in pulled back position against a stop 33, Fig. 4, by a spring 31 and arm 32. The segment 29 is moved forward by a roller 36 into the position shown in Figs. 1 and 6 just after grippers 1 and 2 have passed over it. Roller 36 is fastened to an arm 37 and cam 38 both of which are driven by gears 39, 40 and 41 making one revolution for each time that a pair of grippers 1 and 2 pass over the segment.
  • a brush 42 Cooperating with the segment 29 is a brush 42, Figs. 4, 5 and 6, rotatably mounted on a shaft 43 and swinging freely by means of the arms 44 and 45 from a pair of arms 46 and 47.
  • the arms 46 and 47 are secured to a shaft 48 suitably mounted in bearings, not shown, and are adapted to be raised and lowered by the cam 38 through arms 49 and 50 and roller 51 so that brush 42 will clear the grippers 1 and 2.
  • Arms 49 and 50 are rigidly secured together.
  • the mechanism for tripping the hook 24 to release thepawl 21 comprises the following elements.
  • a rod 52 is hinged to the hook 24 by means of a stud 53.
  • This rod 52 is provided with a toothed projection 54 which is normally held clear of or away from the continuously rotating ratchet wheel 55 by a spring 56 which urges the rod against a stop 57 through the intermediary of a latch 58 which is hinged to the rod 52 and held in a horizontal position by a stop pin 59.
  • the latch 58 has a lip 83 projecting downwardly therefrom which is in the path of a finger 60 secured to the ratchet shaft 30 011 which thesegment 29 is also secured.
  • the ratchet wheels 22 and 55 are assembled together as shown in Fig. 8, the ratchet 2 being provided with internal teeth normally engaged with a gear 61 which is keyed to the driving shaft 17, the two together forming an adjustable coupling or clutch.
  • Ratch- T et 55 is secured to a sleeve 62 on the outer end of which there is provided a flange 63 having clutch teeth 84 similar to the gear 61.
  • the teeth of the flange 63 engage internal teeth of the ring 64 secured in the end of a hand wheel 65.
  • a compression spring 66 is provided between a washer 67, which is secured to the end of the shaft 17, and a collar 68 secured to the sleeve 62. This holds the assembly 22, 55, 62,64 and firmly against the face of the cam 16 and maintains the internal and external teeth of wheel 22 and gear 61 engaged.
  • a compression spring 69 maintains the internal and external teeth of flange 63 and ring 64 in engagement.
  • the hand wheel 65 is provided with gear teeth 7 O which mesh continuously with a gear wheel 71.
  • the gear ratio of gears 7 O and 71 is such that the gear 71 makes one revolution for each cycle of the grippers, and the gear wheel 71 turns on a pin 72 which is secured in a bracket 73 bolted to a part of the machine frame 74.
  • a pin 75 is secured in the gear wheel 71 and as this pin reaches its top position it will lift the roller 76 which is secured to the hook 24, Fig. 7, by means of a pin 7 7' unless the knife drive is in motion in which case the hook 24 will have been raised and held up by the roller 26 on the cam 16 as described in the foregoing.
  • Tobacco leaves are fed into themachine and caught by their butt ends between grip- .pers 1 and 2, Fig. 4.
  • the cam 38 raises 3 the brush 42 out of their path and then allows it to descend upon the tobacco leaves. 6
  • the segment 29 has been cooked forward by the motion of the roller 36 which then releases it and passes on.
  • the tobacco leaves as they are pulled along over the segment 29 are held down thereon by the brush 42, Fig. 1.
  • the tension or pull of the leaves on the segment 29 maintains it in the forward position sincethis overcomes the pull of the spring 31 until the tips of the leaves have been pulled out from between the brush 42 and the segment 29.
  • the spring 31 then pulls the segment back together with the finger 60, Fig.
  • Fig. 1 the knife 3 is stopped at the'lowest position A, leaving only sufficient space for the grippers 1 and 2 to pass thereunder. This setting will leave the maximum length of stem in the leaf.
  • the knife may be set at any desired position such as dotted line positions B or G and suitable dial graduaticns which may be marked on the hand wheel. to indicate inches. -When the hand -wl'1-eel 8 is released the clutch is reengaged in the new position which is chosen for any length of stem desired to bemaintained in the leaf.
  • the third adjustment is for setting the wheel 71, Fig. 8, so that its stud 75 will lift the hook. 2d and set the knife in motion at any desired time.
  • This setting is necessary in cases when it is desired to limit the length of stem that will be taken out or when the measuring mechanism is to be disconnected and a definite length of stem taken out regardless of the length'of the leaves.
  • This settin is made by pushing in the hand wheel thus disengaging the coupling parts that V the ring 647 and turning the hand wheel until the desired reading is indicated on the outer scale on the ring" 64 by the arrow on the flange 68, Fig. 9. Releasin g the haml wheel rcengages the clutch.
