Abstract: 8636. Davis, L., and Hendriks, H. April 25. Cigarette - making machines.-R e l a t e s to cigarette - making machines producing a continuous cigarette rod, and consists of improvements in the appliances for forming the tobacco rod and for pasting and folding the paper strip or wrapper. Fig. 1 shows the improved appliance in plan view, Fig. 3 a sectional plan of the pasting-device on an enlarged scale, and Fig. 6 a plan of the folder, of which sections at a, b, and c are shown in Fig. 7. The combed and disintegrated tobacco is showered into a hopper which discharges it upon the endless travelling band C, at the sides of which are flange pieces A<12> which form a trough. The tobacco is carried beneath a pressure roller C<5>, beyond which is a cover-plate C<20> which prevents the tobacco from expanding. It is next compressed laterally between a pair of slightly-converging metallic bands passing round horizontal pulleys C<8>, C<9>, C'‹, C<11> and guide-rollers C<37>. The bands convey the tobacco between a pair of grooved rollers C<21> arranged one vertically above the other. The grooved peripheries of these rollers form the already compressed tobacco into a rod of circular section, which immediately enters the mouthpiece E' of the folding-device. The mouthpiece consists of a tapering channel covered by a concave presser blade E<4> and having spring blades serving to guide the tobacco rod in the usual manner. The folder E, Figs. 6 and 7, is formed of plates E<10>, E", of whieh the former is divided longitudinally by a slot E<6>. An endless canvas tape carries the tobacco rod and paper strip through the folder. The upstanding edge of the tape and paper on the right-hand side, Fig. 7, is turned over by a flange H<24> so as to bring the paper in contact with the bevelled edge of the paste-wheel H<3>, Figs. 1 and 3. The cover-plate E<8> separates the left-hand edge of the tape from the paper on which it had been previously folded down, and the left-hand edge of the tape continues upstanding through the slot E<6> to the end of the folder. The right-hand edge of both tape and paper are turned down by the curved edge E<12> upon the left-hand edge of the paper, which has passed beneath the cover-plate E<8>, and a pasted seam is thus formed. The cigarette rod then proceeds to the cutting-mechanism. The pastewheel H<3> passes through a slot in the bottom of a paste-cylinder H. A weighted piston, upon which additional pressure may be placed by means of a screw, rests upon the paste, and a series of three vertical grinding-rollers H<17>, 18, H<19> are arranged at the bottom of the paste cylinder to crush any lumps or small particles in the paste. Scrapers H<7> remove paste from the faces of the paste-wheel, and an adjustable scraper H<10> regulates the amount carried by its bevelled edge. A clutch L on the main shaft A<3> of the machine enables the tobacco picking and compressing devices to be run independently of the rest of the apparatus. The Provisional Specification describes a tobacco combing and disintegrating device, and cutting-mechanism and delivering-mechanism for the cigarettes. For the first named purpose, rollers furnished with intercalating pins are employed, clearing-rollers being provided for each combing-roller. A pair of magnetized rollers removes nails or fragments of iron from the disintegrated tobacco. The cutting-mechanism consists of a longitudinally-reciprocating carriage supporting a curved knife blade adapted to sever the cigarette rod at the moment that the carriage is travelling at the same speed. The cigarettes are received by a conveyer band provided with hooks or bent fingers and mounted upon an oscillating frame or lever. The conveyer band discharges the cigarettes into a suitable receptacle.
