Abstract

414,762. Removing dust on generation. COFFIN, E., RUAU, F. F., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Feb. 11, 1933, No. 4278. [Class 8 (ii).] In a tobacco feeding apparatus, dust generated by picker rollers 7 is arrested by rollers 10 or other surfaces and carried away through a duct 9<a>. The rollers 10 are scraped by the edges 19 of the duct, and are geared together and operated by pawl and ratchet mechanism. The suction duct 9<a> is partitioned to form inlets 22 each connected with a division of the conduit 9 to render the flow uniform. The forward wall 22<a> of the trough of the cigarette making machine is formed as a movable member carried by a guide 23 and is struck by a hammer at intervals to prevent accumulation of dust.
