Abstract: 211,905. Hohn, M., Fritz, A., and Bauschlicher, A. Sept. 1, 1922. Cigar-making machines. -The machine supplies in succession quantities of tobacco each sufficient for one cigar, and gives each quantity a preliminary shaping, the tobacco being then rolled to form a cigar-bunch and finally wrapped to form a complete cigar. The driving shaft a, Fig. 1, drives feeding-rollers 2, 3 continuously and actuates intermittently the other parts of the machine through shafts e, g and cross-shafts m, w. The shafts g, m and ware set in motion by a clutch f operated by a pedal 8<8>. The tobacco is contained in a hopper 1 closed by arcuate plates 7, 8<7>. The plate 8<7> is mounted on an arm connected to a sector 8<4> pivoted on the shaft 2<1> of the roller 2. On depressing the pedal 8<8>, a lever 8<12>, actuated through links 8<10>, 8<9>, engages a stud 8<13> on an arm 8<3> attached to the sector 8<4>. The sector is rotated, together with the plate 8<7>, to the position shown and is then locked by a spring pin 8<6>. The hopper 1 now being open, tobacco is showered upon an intermittently-moving belt 11 assisted by a rotating spoked wheel 8. The roller 2 is made in three parts, the centre part rotating faster than the others, the tobacco thus being fed in larger quantities to the centre of the belt 11. The tobacco so fed is carried, during the intermittent motion of the belt', beneath a gauge 16 and delivered into a carriage 30 where it is pressed down by a plunger 22. The gauge 16 may comprise a shaped strip of metal or two rotary brushes mounted side by side and slightly inclined t'o one another. When sufficient tobacco has been fed, the pin 8<6> is automatically released, the arm 8<3> being withdrawn by means of a spring 8<@> and the hopper 1 closed. At the same time the pedal 8<8> is raised and the clutch f disengaged, thus stopping the machine. During the time that the tobacco is being fed to the belt 11 the carriage 30 containing another tobacco charge is transferred by means of pin-and-slot mechanism o to a position above the rolling-nest 43. The tobacco charge is pressed into the nest through the hinged base of the carriage 30 by a plunger 3<5>. The nest comprises parts 43, 44 which fit together to form a closed cylinder. The parts are provided respectively with two and three flexible rollers as hereinafter described. The part 44 is resiliently mounted on an arm 46 and the part 43 is rotatable about the axis of the cylinder by means of a cam 50<1> and linkwork 49, 48<1> thus opening the nest upwards or downwards for the reception of the tobacco or the ejection of the completed cigar. The tobacco introduced into the nest is rolled to form a bunch. The nest is then opened upwards sufficiently to receive the end of a wrapper placed on a table 86 and the cigar is wrapped. The wrapper end is introduced by means of a blast of compressed air issuing- from a flattened nozzle 95, the air being released by depression of the nozzle over the nest. The end of the nozzle may comprise a single slit or a row of perforations. The wrapper is pasted on the table 86 by a roller 98 which is reciprocated, through a lever 96 and a link 97, by an eccentric on the shaft' w. The roller 98 pastes the wrapper during its swing to the right. It then picks up paste from a roller 105 and in swinging to the left is raised above the table against the action of a spring by means of a pin 101 riding over a crescent-shaped pivoted cam 102. In the rolling mechanism shown in Fig. 10, the five rollers in the nest 43, 44 each comprise a series of laminae 59 mounted upon a flexible spindle 60. The rollers are rotated by pinions 50, 52 engaging a central driving spindle which is driven from the shaft w, Fig. 1, by a belt x. The space enclosed by the rollers conforms to the shape of cigar required and the size of each lamina is so arranged that its peripheral speed is the same as that of the part of the cigar on which it bears. Supporting rollers 65, 66, Fig. 10, are provided in the nest. The rollers may be constructed only partly of laminae or may consist entirely of conical and cylindrical parts connected by universal joints, the shape of the parts being chosen to give the desired shape of cigar. The nests are made readily detachable, and interchangeable nests are provided. A clutch and reversing gear are employed in the driving-mechanism of the rollers in order that the wrapping process may be modified as desired.
