Abstract: 19,239. Dunn, J. W. March 21, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. C,'i.qars.-Relates to machines for forming the head ends of cigars, the wrappers of which have been applied by hand or otherwise up to the stage shown at A in the plan view, Fig. 3. The cigar is placed between the jaws 84, 85 of a clamp, which is carried by a semi-cylindrical frame 66 adapted to revolve for the purpose of completing the cigar head. A single revolution can be given to the principal shaft of the machine by the depression of a treadle-lever which sets a friction clutch in operation, and before the machine comes to rest the cigar head is rolled and pasted, the tuck end trimmed, and the finished cigar ejected. Fig. 18 shows the frame 66 in end view, and the cigar c in section, the jaws 84, 85 being in the closed position. The jaws close under spring control as soon as the arm 90 is released from the action of the cam-actuated lever 91, Fig. 3, and remain closed during the four revolutions of the frame 66 and during the subsequent trimming of the tuck end of the cigar by the knife blades 95, 96. The blade 95 is shown more clearly in Fig. 17 ; the blade 96 is V-shaped or notched. The ejector arms 97 throw out the finished cigar after the frame 66 has come to rest. By adjustment of the carriage 99 on the knife-rod 98 and ejector-rod 89, both of which are mounted in the frame 66, the knives can be adapted to trim cigars of varying length. The head end of the cigar is formed in a conical recess in the thimble 67, of which Fig. 20 is a detached view looking inward. The thimble is mounted upon a carriage 115 sliding horizontally under the control of a cam, which causes its withdrawal towards the right at the moment that the cigar is to be ejected. Within the conical recess 114, Fig. 20, is a concave leaf-spring 120, which renders the recess to some extent self-adaptable for varying sizes of cigars. The surplus portion of the wrapper overhanging the outer angular side 67<a> of the thimble 67 is cut at intervals by the blades 136 of a knife 123, Fig. 9, mounted on a rock shaft 122 and moving between the thimble and a thin vertical plate 144. The shaft 122 is operated by a stepped cam, which causes each blade to act in turn. The projecting portion of the wrapper is guided so as to fold smoothly round the cigarette head by means of the folder arm 145, which is cam-actuated so as to swing both in the horizontal and vertical planes in accordance with the requirements of the folding or guiding operation. The recess 114 is partly constituted, as shown in Fig. 20, by the extremity of a pivoted arm 155 shown in section in Fig. 10. Paste is supplied to the cigar head through the arm 155, and the arm is caused to hammer the head at the same time by the action of a serrated cam upon its controlling-lever. Before the arm 155 resumes its normal or raised position the hammering action ceases, and a smooth and even pressure is exerted on the cigar head for the remainder of its rotary movement. The thimble 67 is fastened on the carriage 115 by means of an interrupted dovetail groove which enables it to be easily removed. The paste cylinder, which communicates with the arm 155 through a flexible tube, is shown in section in Fig. 24. The threaded piston 179 moves in the cylinder 175, which is fixed in the tubular support 176 by means of a bayonet-joint 197 and screw 177. Into a groove 181 in the piston-rod fits a key 182 on the sleeve 183, which is provided with a ratchet-wheel 185 adjustably actuated from the shaft 73. The blades 95, 96, and 123 are so mounted as to be easily detachable for sharpening purposes.
