Abstract: 15,120. Gardner, M. M. July 7. Cigars.-Relates to cigar - making machinery. Fig. 4 shows a partial longitudinal s e c - tion, Fig. 6 a partial transverse section, and Fig. 15 a view of the apron-operating mechanism. Superposed leaves of tobacco, fed into the machine between travelling belts, are pressed and flattened by an ironing-appliance into a uniform ribbon, which is severed into filler sections by the knife K, and transferred to the magazine m by a plunger. The shear plates s<1>, s<2> assist the severance of the filler sections into charges z by the knife a secured to the holder a', which is reciprocated by means of a grooved rotary cam driven by toothed gearing from the shaft u. The charging-pocket v is formed by the conjunction of the knife a, the horizontal sliding carriage B, the vertically-guided plate b<6>, and the ejector b. The carriage B is connected to the filler-section transferring-member D by the link f<4>, angle lever f<3>, f<1>, and roll f. The ejector b is actuated by means of a second groove on the cam which actuates the knife a; it is provided with openings c<4> for the passage of stop pins b<9> screwed into the knife-holder a<2>. The plate b<6> is detachably secured to the ejector b by a spring catch b<8>. In the position shown in Fig. 6, a charge z has just been severed. The carriage B then moves to the right, and the opening with which it is provided permits the downward movement of the parts a, b, b<6> under the action of the rotary cam. The stop pins b<9> engage the lower ledge of the recess b<10>, and limit the downward motion of the plate b<6>, causing the spring catch b<8> to be disengaged. The ejector b continues to descend, until it has forced the charge z and binder L into the bight i<1> of the rolling-apron i. On the upward movement of the ejector b, the spring catch b<8> is engaged and the plate b<6> carried up. The forming-roll d<3> is mounted on a rod secured between the parts p<2> of a pair of bent levers p mounted on the rock-shaft n, actuated from the cam M by the link n' and crank n<1>. The parts p' also carry a plate p<3>, a swinging friction roll d', and a spring clip l. The flexible rolling- apron i, secured at i<4> to the table holder t<4>, passes round the fixed rolls d, and is secured to the link i' jointed to the spring-held lever r, which has a cam extension r<3> operated by the roll p' on the levers p, so that, when the latter are in the rearmost position, as shown in Fig. 4, the lever r is moved against the pull of the spring r<2>, and the apron i is slacked to form the bight i<1>. The binder L, Figs. 4 and 6, is held by the clip l and friction roll d' horizontally above the bight i<1> ; on the descent of the charge z, the end of the binder is released by the clip l, and falls into the bight i<1> with the charge above it. The forward movement of the levers p first releases the lever r, so that the end r<3> descends, and the apron i is tightened a little. The forming-roll d<3>, as it advances, causes the charge to be enveloped by the binder L, while the friction roll d' gradually yields. At the end of the forward movement, the rolled and completed bunch is discharged over the front of the table t<3>, and a new binder resting on the table g is then secured beneath the clip l. The table g, Fig. 15, carries at one side a tripping-device h<1> adapted to swing the friction roll d<2> upwards and to cause the arm d<5> to ride on a shoulder h<2>. The frame e<3>, Figs. 4 and 6, is adjustably secured to the bed e'. A space plate may be secured to the ejector b when it is desired to increase the charge.
