Title: Improvements in or relating to tobacco feeding apparatus
IPC: A24C5/39
Filed: 1936-04-09
Abstract: 477,986. Tobacco-feeding machines. RUAU, F. F. (Molins, D. W.) April 9, 1936, No. 10509. [Class 130] Tobacco is fed into one end of a downwardly-directed passage, having opposed surfaces each movable towards and away from one another and having components of movement in the direction of movement of the tobacco through the passage when the distance apart of the surfaces is a minimum, and is removed from the opposite end of the passage by a transfer element. The tobacco enters the passage at a greater speed than that at which it is removed and the reduction in speed compacts the tobacco without the application of any positive pressure or ramming action. A pronged element 8 regulates the quantity of tobacco supplied to a hopper 5 from a container 6 by a pivoted flap 7. The tobacco is withdrawn from the hopper by a carded roller 10 and is showered by a fastrotating picker roller 15 into a downwardly directed passage 16 formed by parallel walls 17, 18 from one of which end walls project. The walls 17, 18 are carried by cranks 19 .. 22, and assist in feeding the tobacco towards a transfer element 23 from which it is removed by a picker roller 25 and discharged into the trough 26 of a cigarette-making machine. The quantity of tobacco carried on the roller 10 is regulated by an oscillating rake 11 and a reserve of tobacco between the roller 10 and a brushing roller 12 is periodically pressed against the roller 10 by a tamper 13. In a modified construction the picker roller 15 showers the tobacco on to a fast-moving conveyer belt from which the tobacco is directed into a vertical passage 16 by a fastmoving belt or roller.
