Abstract: 19,448. Bunn, J. Sept. 13. Cigars.-Relates to a machine for rolling the bunch in its wrapper and cutting and pasting the latter at the head end. Standards, Fig. 4, constitute bearings for twoshafts4, 15, of which the former is driven from the pulley 5 by means of a friction clutch whenever the lever 12 is pressed outwards by the operator's knee. The shaft 15. geared at the left end to the shaft 4, is provided with a long keyway along which slides a pinion within the support or box 16, the said pinion gearing with toothed wheels on the rubber-faced rollers 18, 19, Fig. 10, which together with rollers 20, 30, 31 serve to roll the cigar bunch. These rollers, together with the paste box 60, the headforming device 50, and the wrappercutting knife 75, Fig. 15, are all supported on a carriage, of which the uprights 16 and 17 constitute the ends, and which slides upon the shaft 15. The roller 20 is frictionally driven from the roller 19, and itself drives by friction a pair of rollers 30, 31, Figs. 4 and 10, independently mounted on arms 118 pivoted under the control of springs at the end of a forked plate 36 which turns about a shaft 41 in the carriage. A spiral spring on this shaft tends to lower the rollers 30, 31 against the cigar bunch, but a rod 36<1> at the rear end of the plate 36 can be depressed by a treadle-lever so as to raise the rollers into the position shown in Fig. 10. The roller 20 is eccentrically mounted upon its supporting-shaft, so that its pressure against the rollers 19, 30, and 31 can be varied. An adjustably-inclined table is fixed at the lefthand end of the machine, and upon it the wrapper is laid with one end within a wrapper-holder consisting of a wire loop carried on a rod 86 and in contact with the bunch. The carriage is caused to traverse towards the right by starting the shaft 4 on which is a worm 67 with which engages a lug 66, Fig. 5, projecting from the carriage. By mounting the lug on a sliding plate capable of yielding against spring control for a short distance, the carriage is left at rest until the rollers have been set in motion for a short time. Towards the end of the movement of the carriage, the pitch of the worm 67, which consists of square-sectioned wire adjustably coiled upon the shaft 4, becomes less, and the wrapper is wrapped about the bunch at the head or left end with a correspondinglydiminished pitch. The carriage is free to turn through a small angle on the shaft 15, its movement being limited by the lug 66 or the stop 135 coming in contact with the worm. On depressing the treadle-lever so as to raise the rollers 30, 31, the whole carriage turns backward so as to disengage the lug 66 from the worm, as shown in Fig. 5, and the carriage is immediately carried back to the left-hand position by the action of the spring 73 and band 71 attached to the carriage. An automatic device 92, 97, Fig. 4, is arranged to withdraw the rod 86 and its wrapper-holding loop from the cigar as the carriage approaches the right. Fig. 12 is a section showing the conical depression 51 in which the head of the cigar is shaped. Paste enters by an aperture 59, and the recessed plate 50 has a detached part 52 which moves outwards to release the cigar through the medium of the link 57, lever 55, and pin 53 when the treadle-lever is depressed. The knife 75, shown in Fig. 15, is mounted close to the head-shaping device at the extreme left of the carriage. A draw-cut of the tobacco leaf resting on the plate 58 is effected by depressing the thumb-plate 79, the knife having a pivot 80 uniting it with the plate 78 and a curved slot 76 through which the pivot 77 of the plate passes. A spring 84 restores the thumb-plate and knife to their normal positions.
