Abstract: 22,561. Williams, J. R. Dec. 11. Cigars.-Relates to cigar-making machines, and particularly to machines for forming the head ends of cigars. Fig. 1 shows a plan of the machine, and Fig. 4 a sectional elevation on line 4-4, Fig. 1. The cigar, after having been wrapped and whilst the loose end of the wrapper is projecting from it, is placed in the machine, which then pastes the end of the wrapper and applies it to the cigar. The whole operation is performed whilst the main shaft 31 makes a single revolution, and clutch mechanism is provided to disconnect the shaft from the driving-gearing 32, 37, 38 at the end of the revolution. Any suitable form of clutch may be used, but Figs. 21, 22, 23, and 24 show a form of clutch specially adapted for this purpose. The gear-wheel 37 carries a toothed annulus 43 engaging a dog 42 pivoted on a block 40 fixed to the shaft and fitted with a spring 49. A loose disc 36, mounted close to the gear-wheel 37, is formed with a tooth 48, which is normally engaged by a pawl 33, Fig. 1, and carries a spring bolt 45. When the pawl 33 is lifted, the dog 42 engages the teeth, and the shaft 31, Fig. 1, is driven until the disc 36, being stopped by the pawl engaging the tooth 48, causes the tail end of the dog to strike the bolt 45, the dog being thus disengaged from the toothed annulus. A stop 46 serves to ensure the proper relative position between the parts of the clutch. The pawl 33 is operated through a link 50 by a weighted lever 51, or by other means. The cigar is placed in a rotary frame consisting of a divided gearwheel 55, 56, the parts of which are shown separated in Fig. 4. The parts 55, 56 are arranged to turn in a divided casing 57, 58, and are rotated through gearing 80, 81, 82 from the shaft 31. Mounted on the rotary frame are clamp arms 68, 69, which are brought together by the action of a pin and slot 76 and pinions 73, to grip the cigar when the casing 57, 58 is closed. The casing is closed by a spring, and locked by a catch 78. The gear-wheel 80 is cut away so that the rotation of the frame 55, 58 ceases before the driving-shaft completes its revolution. The casing is automatically opened by a cam 86 engaging an arm 87, the catch 78 being first freed by an arm 92 moving a sliding spring rod 94. The end of the cigar projects into a conical opening 100, Fig. 12, in a thimble 99, the end of the wrapper resting on the special-shaped surface of such thimble. The loose end of the wrapper is pressed downward on the surface of the wrapper by a rotary arm 193, Fig. 1, to which a rotary and rising and falling motion is given by suitable cams and springs. The arm carries a flexible strip 194, to prevent injury to the wrapper. The wrapper is trimmed by a rotary knife 112, shown separately in Fig. 13, having blades of different length. This knife is detachably fixed to a short axle 114, fitted with a spring 118 to allow its retraction for the removal of the knife, and driven by a cam on the shaft 31 through levers and a vertical rack &c. The cam is shaped so as to cause the several blades of the knife to make individual cuts through the wrapper. Paste is supplied to the wrapper from a detachable cylinder 140, fitted with a piston which is fed forward by a nut and screw actuated through a clutch and connecting-rod from the main shaft 31. The paste passes through a flexible tube 141, and escapes from a nozzle 142, which is pivoted on the frame and is given an oscillating motion by a toothed cam so as to hammer the head of the cigar as the wrapper is applied, but remains at rest whilst the knife blades are acting. The cigar is automatically withdrawn and the tuck end cut after the head is formed, by the following mechanism :- Pivoted knives 205, 206, Fig. 1, are carried by a carriage 209, adapted to slide on the main shaft 31 and on a rocking shaft 64. The knives are closed by the movement of a sliding plate connected to their tail ends and actuated by a cam turning with, but free to slide on, the shaft 64, which is rocked by a cam 23 acting on arms 233, 234 upon it. The carriage 209 is reciprocated by a grooved cam 224, acting through rocking arms connected to a graduated bar 228, to which the carriage is adjustably connected. When the head of the cigar is finished, the carriage slides forward, and the knives 205, 206 close on the tuck end of the cigar by a spring action so as to grip it firmly enough to bring it back with the carriage, the rotary frame at this time being open. Upon the return of the carriage the shaft 64 is rocked and the cam closes the knives 205, 206, and thus cuts off the tuck end of the cigar. The parts of the machine are now in their initial position, ready to receive another cigar.
