Abstract: 4626. Fairweather, W., [Boucher, A. L.]. Feb. 29. Cigarette - making machines.-In machines for tipping cigarettes with cork or other material, the cork &c. web is fed to the cigarettes in a direction parallel to that of the axes thereof, the web being of a width sufficient to permit the edges to overlap on the cigarette, which may be turned over on the carrier should the printing &c. be on the upper side. The cigarettes in the holders 17 on the carrier 9, which consists of two sprocket chains 10, 11, are kept in position by a flexible apron 18, and are intermittently fed forward to the tipping-mechanism, where the end of the cigarette, correctly positioned by suitable guides, rests over a plate 25, Fig. 12, to which the cork web is fed. A length of this web is cut between the knives 126, 127, the concave edge 128 of the latter cutting the web and carrying up the edges against the cigarette. On completion of the cutting, the edges of the web, which has previously been pasted, are folded about the cigarette by means of spring-pressed fingers 3P, 37 carried by arms 36, 35 operated successively by cams on the shaft 22. The rollers 42, 41 engage during the operation with the shoulders 44, 43, and cause the fingers to rise and ride over the cigarette, pressing down the cork web. During the application of the web the cigarette is held by a presser 28, Fig. 2, pressing on the apron 18 and operated by a cam 30 and a spring 31. On the next step forward, the seam of the tipped cigarette is pressed by a presser 32 carried by the same rod 29 that carries the presser 28. The web is fed from the spool 53<a>, Fig. 2, under a paste wheel driven by a ratchet and pawl by means of a cam 60 on the sbaft 22, and through a gripper-feed device to the plate 25, where it is held by a presser 85 during the return stroke of the gripper-feed device. This device, Figs. 7 and 8, comprises a rocking member 67, to which is fulcrumed a member 73 ; a plate 69 with side guides 70, 71 is attached to the member 67, while a gripping-plate 79 is suspended from a post 77 attached to the member 73, the plate 79 being attached to the side guide 70 of the lower plate 69 by a rod 80. The lever 73 is rocked by means of the cam 76, Fig. 2, causing the gripping-plate 79 to be rocked, and, by reason of its being fulcrumed at 80, its forward end grips the cork web, and a continuance of the rocking of the member 73 causes the member 67 to rock and carry forward the cork web the requisite distance. When the cam 76 releases the member 73, a spring 92, Fig. 2, carries the member 73 back ; this on striking the plate 84, Fig. 7, rocks the member 67 backwards into position for the next feeding movement. The cigarettes are fed on to a carrier 9 from a hopper 114, Fig. 1, between a rotating drum 115 aud a casing 118 rocked by a lever 113 by means of the rod 111 operated by a cam on the shaft 22. A tumbler 120, pivoted at 121 and attached by a link 124 to the casing, receives the cigarettes singly and deposits them in the holders 17 of the carrier. Any cigarette with its printed side uppermost is turned over by grippers 99, 100, Fig. 11, rotatable by a hand-lever 101 operating a pawl and ratchet with but two teeth, the rotation being completed by a spring 110 acting on a cam 109. The sprocketwheels of the carrier are driven by means of gears 23, 24, the former of which is mutilated in order that the motion of the carrier may be intermittent. Specification No. 9181, A.D. 1907, is referred to.
