Abstract: 16,906. Gabrielsky, R. Aug. 2. Cigarettemaking machines. - In a machine for applying tips or mouthpieces of cork &c., a cigarette, fed forward by a pushbar and thrust down from a guideway, is kept still by holding - jaws, sliding gum-boxes close on the projecting end, a magazine of cork blanks is raised and lowered while the gum - boxes slide apart, a concave tongue comes up each side of the adherent blank, and curved fingers fold the sides over to meet successively together and overlap, while taking gum for the joint from a reciprocating rod. The holding-jaws are then opened to drop the cigarette upon an endless belt which conveys it to a receptacle. The push-bar 10, which occupies a guide-tube 9 protruding from a frame 7 on the table 1, and is combined with a rack on a feather in the frame, is operated by a wheel 17 with a crank-pin 16 which lifts a vertical rack 14, to be pulled down again by a spring. A cigarette supplied to a lower guideway 26 by a small hinged hopper is pushed under an upper guideway 33 which is terminated by a stop-plate 40 and has hinged leaves or jaws 34 below to receive and release the cigarette over the holding-jaws 73. The guideways form a margin of a plate on a transverse bar 27, which is hinged so as to allow slight adjustment by a screw 28 on a post 29. To open the supporting-jaws, arms 37, Fig. 4, on the gum-boxes 38, 39 bear upon tangs which are pulled by closing-springs 36. The released cigarette is pushed down to the table by a needle 43 and discharge rods 44 sliding in vertical guideways 41, 42. These rods hang from the bent head of a vertical rod 46 which is reciprocated by a lever 49 over a cam 51. The holding-jaws are slides 73 on the table 1, which, when closed, form a trough with slightly-inturned edges, and they are actuated by levers 78 with springs and rotary cams 87 having a large circular part. The gum-boxes 38,39, sliding on hinged guide-bars 89, have their inner ends concave and perforated and contain a partition pierced by an adjustable valve. Reservoirs 97 are carried by the boxes to keep them full of gum at a pressure which can be adjusted by varying the tension of springs 102, pulling down pistons. The reciprocation of the gum-boxes is effected by means of springs 96 pulling on the arms 37 and by levers 104 which converge to adjacent fulcra 107 and are connected between them by a common link 105 to a crank q of short throw. The hinged guide-bars 89 are held down against accidental elevation by springs 110 which can be disengaged by pressing push-bars 111. In the magazine 112, the cork blanks are pressed up to its mouth by weights 119 on cords from a false bottom, and the magazine, being attached to a vertical slide 114 on a guide-bar 115, is reciprocated by a snail cam 117 and a spring 123. The concave tongue 129, for bending the applied blank up on each side, is attached to a pinion in gear with a rack which is operated by a lever 130, Fig. 4, when a bar 133 having an inclined slot is raised by a lever 108 worked by a cam 106. The first-acting folding- finger 147 makes a quarter-revolution to the centre and back with a cranked spindle, which is connected by a link 145 to a reciprocating rod 142 in a tubular guideway 143. The outer end of the rod has a spring and is connected by a link 141 to one arm of a bell-crank 139, the other arm of which is struck by the rising bar 133. The bell-crank is pivoted on the post 140 which carries the tubular guideway 143. The second-acting folding-finger 155 is similarly operated by means of the bell-crank 159, a long lever 56 with a rigid branch 54, and the cam 51 acting thereon. The gumming-rod 152, which reciprocates through a gum-box 151 having a reservoir 154, is operated by a lever 163, a bell-crank 164, a lever 167, Fig. 4. and a cam 168, Fig. 2. The endless belt 60 which conveys the tipped cigarettes away passes through curving guides 70, 72, Fig. 3, and is prevented from slipping by a pressing-wheel 66 on springs 68. Guide-wires 81, Fig. 2, lying between the holding- jaws retain the cigarettes centrally on the belt when the jaws open.
