Abstract
21,013. Prokop, J. Sept. 14. Sieves with compound motion - The unbalanced fly-wheel A which is used for gyrating a freely-suspended plansifter D is mounted in a separate frame B, to the upper or lower sides, or to both sides, of which the sieve frames are secured. In the latter case, the upper and lower sieve frames are connected by conduits for transmitting the material from the upper to the lower systems. In the arrangement shown in Fig. 5, a compensating-weight P is used below the frame containing the fly-wheel for the purpose of bringing the centre of gravity of the system substantially into coincidence with the centre of gravity of the fly-wheel. The weight may be secured to the bracket B, or a smaller weight P<1> may be used suspended by rods r. The compensating-weight and fly-wheel may also be arranged above the sieve frame. To prevent strong oscillation at starting, the eccentric mass Q of the fly-wheel, Fig. 7, is arranged as a loose piston in a casing 7, containing air or a liquid, springs 9 normally holding the weight near the axis 1.
