Abstract: 15,684. Schaeffer, L. A. July 8. Cigars.-Relates to a cigar-making machine of the rolling-apron type. The wrapper is cut by means of a cutting-roll J and a die-plate H, Fig. 18, adapted to rest on a grating g, Fig. 4, disposed in the rolling-board G above a suction chamber. The cutting-roll J is carried by an arm D, Fig. 4, operated from the power shaft C by a cam K; Fig. 6, and, by a tilting movement of its support, is adapted to cut on one side of the die as it moves forwards and on the other as it retires; a bridge 10, Fig. 4, overlaps the step h<1> during the forward movement and, by means of a wing, is moved out of the way on the return stroke. On completion of the cutting, the cie-plate H is raised by means of a lever and the cam M, and the wrapper remains on the perforated apron 2 on the rolling-board G. The wrapper is pasted by means of a paster 16, Fig. 4, which is carried by an oscillating arm operated by means of a slide 26 and the projection 28, Fig. 18, on the standard H<1> of the die-plate; this projection is bevelled on the lower edge in order that the slide may be operated on the upward stroke only. The paster 16, Fig. 4, when over the wrapper, is tilted down by means of a post 33 engaging a finger 29. The bunches are delivered singly from the mould-board Y into a hopper 35, Fig. 2, and bunch-receiver 36, Fig. 30, whence they are taken singly by a gripper and deposited on the rolling-apron. The gripping-members are pivoted on a rod 22 mounted on a slide block 45, and are operated by means of fingers mounted on a sleeve 49. This sleeve is operated by cam N, Fig. 6, and lever 43, the relative motion between the sleeve 49 and rod 22, Fig. 30, necessary for operating the gripping-members being obtained by means of a slot in the slide 45, through which the standard 48 passes and then the entire gripping-mechanism moves in unison to deliver the bunch, the gripping-members being released on the return movement. The bunch immediately above is prevented from falling during this operation by means of a spring-controlled plunger 53, Fig. 30, which presses the bunch against the opposite wall of the bunch-receptacle and releases it at the proper moment by means of a projection 56 on the sleeve 49. The pocket is formed by a rearward sliding movement and an oscillating movement of the rolling-board in conjunction with the wrapping roller. The rolling-board G, Fig. 27, is mounted on a short spindle 62 rotatably mounted on a slide 63, which is operated from the standard H', Fig. 18, by means of a link s<1> and lever s<2>; the oscillatory movement is derived from the spindle 71, the wings 72 of which engage with wings 64 on the spindle 62, Figs. 18 and 27, the spindle being operated from the cam R, Fig. 6, by means of the rocking-sleeve 67 and link 70, Fig. 6. The sliding and oscillatory movements of the board are modified by the roller which takes into a slot in the base of the board. The wrapping-apron, which is flexible and elastic, is attached at one end to the rolling-board and at the other to a frame 77, Fig. 25, which is pivoted and controlled by a weighted lever 83, Fig. 6, having at its extremity a roller V<1> riding on a cam V ; the cam is adapted to release the roller V<1> as the rolling of the bunch proceeds, and thereby causes the tension of the rolling-apron to be regulated by the weighted lever 83. The rear end of the wrapping-apron is held in a spring-controlled bar 160, Fig. 32, slidably mounted on the frame 77 and operated by means of a projection 162 on the rear end of the rolling-board, thereby keeping the apron in the correct working relation throughout the wrapping of the bunch. The wrapping-roller 3, which is bottle-shaped, is carried by an horizontal arm E, Fig. 4, mounted on the post E<1> which is caused to swing by means of the cam T, rack 75, and segment 74, Fig. 6. As the wrapping-roller travels over the rolling-board, this moves forwards and outwards to wrap the tip of the bunch more effectively. The cigar is delivered on the completion of the wrapping to a pair of discharge grippers 86, 87, Fig. 25, which present it to a rotating cutting-disk 85. In order that the cigars may be cut to a given length, a spring-controlled head presses the cigar against a stop-plate 153. The grippers, operated by an arm 90 from the cam W, Fig. 6, are held closed by the spring 93, Fig. 25, but are open in the receiving position and again at discharge, the latter effect being obtained by a set-screw 94 ; a drop-plate 97 serves to hold them open when in these positions. During the cutting of the wrapper, the grating g, Fig. 4, is raised to the level of the cutting-die h by means of a cam X, Fig. 6, acting through arm 101, shaft 68, arm 100, and stems 103, 105, Fig. 18, gravity causing the grating to return to the level of the rolling - board G on the completion of the wrapper cutting. At tne proper moment, the atmospheric suction is cut off by means of a valve operated by a wing carried by the shaft E<1> engaging a pin 109, Fig 6. The wing has a turned-down lip so that the valve is only operated on the return stroke, a spring opening the valve when released. A part Y of the bunch mould is placed in the machine and arranged to deliver the bunches to the hopper 35, Fig. 2. The bunches are partly ejected by means of plugs 114 mounted on a rod 115 and operated by means of a handle 121. The bunches are confined at one end by a rod 116, and are ejected successively as the mould is fed upwards by means of a finger 138, Fig. 4, operated from the cam Z, Fig. 4, by the segment 141 and arm 143. The mould board is fed upwards by means of the same cam Z through a pawl engaging a line of teeth 133 carried by the mould carrier, a gravity pawl retaining the mould in position. The pawls may be thrown out of gear by means of a bar.
