Abstract: 429,482. Wrapping-machines. INTERNATIONAL CIGAR MACHINERY CO., 5520, 2nd Avenue, Brooklyn, New York, U.S.A. Nov. 16, 1934, No. 33074. Convention date, May 5. [Class 94 (i)] Cigars are fed layer by layer from the bottom of a magazine, the cardboards separating the layers being removed in succession before the delivery of the corresponding layer, and means are provided for stopping the machine if a cardboard is not removed or if the cigars jam in the magazine. The machine may however be adapted for feeding cigars from a magazine in which the layers are not separated by cardboards. The magazine comprising side walls 45 and an end wall 43 is located on a table 16 which is reecessed to receive conveyer chains 38. The bottom layer of cigars is first moved a short distance axially by a pusher bar 68 carried by rods 64 which are urged to the right, Fig. 1, by springs 65 disposed between the bar 68 and the bearings of the rods. Bars 48 which are reciprocated by levers 55 controlled by a cam 28 on the shaft 18 carry at their rear ends latches 61, the vertical parts of which act as stops for the rods 64 while the hook-ends co-operate with recesses therein. As the bars 48 move the pusher-bar 68 is urged against the cigars by the springs 65, but if this pressure is insufficient to move the cigars, the rods 64 are moved positively by the hook-ends of the latches, which are ultimately released by engagement with hooks 66. As the cigars move they lift a rod 70 into alignment with the cardboard A<1> above the layer. At the same time bars 50 which are linked to the levers 55 and are guided in inclined grooves advance a separator plate 52 beneath the cardboard A<1> to raise the upper layers of cigars. A plate 78 pivoted to the side wall of the magazine is lifted out of the path of the bottom layer. Pairs of pivoted grippers 92, 93 are moved forwardly while the separator plate is still advancing under control of a cam 27 on the shaft 18 and on reaching the cardboard A beneath the bottom layer a pin 98 on the upper jaw strikes a stop 99<1> and causes the cardboard to be gripped. At the same time a pin 100 on the lower jaw strikes an arm 105 and causes a pin 108 thereon to lift a small lever 109 on the shaft 26. This causes a locking pawl 113, Fig. 6, to engage a singletooth ratchet 114 on the shaft 19 which drives the chain conveyer 38 and the belt conveyer 40 which transports the cigars from the conveyer 38 to the wrapping - machine. The shaft 19 is driven from a shaft 34 by a chain 36 passing over sprockets thereon, the shaft 34 being driven intermittently by a gearsegment 32 on the shaft 20 meshing with a gear 33. The locking pawl 113 is inserted at a time when the shaft 19 is stationary. The grippers 92, 93 withdraw the cardboard A on their return stroke, and the arm 105 is returned by the cardboard to its original position, thus withdrawing the locking pawl 113, so that when the gear-segment 32 becomes operative the bottom layer of cigars is carried away by pushers on the chains 38. At the end of the stroke the pin 98 on the upper jaw strikes a stop 99 to open the jaws and allow the cardboard to drop. Should the grippers fail to remove the cardboard, the shaft 19 remains locked, and when the shaft 34 is again driven the tension of the chain 36, which passes under an idler sprocket 119 on an arm 120, swings this arm about the shaft 34, this movement being communicated by a link 123 to the clutch-operating lever 124 to stop the machine. The slack in the lower run of the chain 36 is taken up by a sprocket 115 on a pivoted arm 116. Should the cigars jam, the shaft 19 is prevented from rotating due to the stoppage of the chains 38, and the machine is stopped in the same way. If cardboards are not employed, the grippers 92, 93 and co-operating parts are eliminated. Specification 395,554 is referred to.
