Abstract: 395,921. Cigar-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Nov. 5, 1932, No. 31298. [Class 130.] Scrap tobacco is agitated in a hopper 30 above an oscillating drum 32 carrying a pan 63. The pan is projected into the hopper, and coverknives 68 separate a panful from the mass. The pan is retracted, inverted by oscillation of the drum, the'knives withdrawn, and the panful discharged between opened gates 82 into a passage 33. The discharged material is propelled by a plunger 35 towards and into a measuring chamber 36 beneath a vertical plunger 37 working synchronously with a charge-cutting knife 124. The plunger 37 compresses the charge and ejects it through a gate 151 into the bight of a chianti-belt 155 whereon a binder is placed and rolled around the charge as the latter traverses the table 38. Cams 25, 26, 27 mounted on a motor-driven shaft 20 and acting through lever-linkages fulcrumed about the shaft 29 effect the required movements. The half-revolutions of the drum 32 are produced by the engagement of a pinion on the drum spindle 31 with a rack 54 attached to a lever 55 having a roller bearing in a track of cam 25. From the shaft 31 unidirectional motion is transmitted to the agitating blades 47 by way of a one-way clutch. When the pan is beneath the hopper outlet, a cam lever 79 actuates a crank 77 through a rod 78. The crank 78 is attached to a shaft 59 journalled in the framing and projecting into the drum 32 through its slotted end. From a forked bracket on the shaft 59 the movement is transmitted to the pan 63 which is thus lifted into the hopper. In the uppermost position of the pan, a trip lever upsets a pair of levers 70 from a straight line position allowing a spring to close the cover-knives 68 over the pan. As the drum rotates and the pan is retracted, a roller on the pivot of the knives engages a cam-piece 73 on the shaft 59 and reopens the knives. During the transfer motion of the pan, the hinged gates 82 are raised by means of a connecting rod 83 attached to a cam-lever 55, the rod moving one end of a double-lever 84 fulcrumed to a bar 34 and connected by a link 87 to a vertically-guided slide 88 with links 91 connected to the gates. The pan 63 delivers an amount in excess of that required for a single charging of the chamber 36. The surplus accumulates in the passage 33 until it prevents the plunger 35 from completing its stroke. Eventually a finger 102 fails to engage a trip lever 103 linked to a cam 115. The adjacent operating cam 25 is driven from the shaft 20 by ratchet gearing. When the finger 102 fails to engage the trip lever 103, the cam 115 is not drawn aside and lifts the driving pawl of the cam 25, so interrupting the drive of the drum 32 until the contents of the passage 33 have been reduced. As the compressing plunger 35 completes its stroke, a vertically guided rod 123 actuates the charge-cutting knife 124 and the plunger 37. Intervening springs delay the action of the plunger relative to the knife. The rolling pin 39 is mounted in blocks 162 carried by a yoke 163 pivoted in a swingable bracket which in turn is pivoted to the rolling arm 40, thus permitting the angle of the rolling pin 39 to be adjusted for rolling uniform or tapered bunches.
