Patent number: 4312750Abstract: A grain cleaning apparatus (10) for removing coarse and fine foreign materials from dirty grain before storage. The grain cleaning apparatus includes counter-rotating screen drums (18,20). Dirty grain is received in a frusto-conically shaped inner drum (18). Coarse foreign materials are prevented from passing through screen (100) of inner drum (18) and rather move to chute (38) where they fall to trough (40) for exiting from apparatus (10). Chute (38) is located between the output end (36) of the inner drum (18) and the output end (48) of the cylindrical outer drum (20). Grain is prevented from passing through screen (115) of outer drum (20). Fine foreign materials do pass therethrough, however, for exiting from apparatus (10). Clean grain drops from the output end (48) of outer drum (20).A motor (22) drives a secondary drive shaft (24). Shaft (24) drives first and second pulley systems (26,28) to rotate inner and outer screen drums (18,20) in opposite directions simultaneously.Type: GrantFiled: August 11, 1980Date of Patent: January 26, 1982Assignee: David Manufacturing Co.Inventors: Keith A.

Patent number: 4176066Abstract: A dewatering separator device for separating solid particles such as sand, gravel, or the like from a liquid, such as water, and thereby preconditioning the water either for further filtering elsewhere or for permitting the water to be accepted in storm drains. The separator device is of the gravitational flow type and includes a plurality of vertically arranged tubes, each of which has small apertures in the form of thin slits in their side wall. The mixture of solid material, i.e., sand, gravel, and the like, and water is dumped through the top of the tubes, causing the heavier solid material to pass through the tubes where it is collected in a constituent trap, and from which the material is periodically discharged at one location. The water passes through the small slits in the sidewalls of the tubes and is discharged from the separator device separately from the solid material. The device has a movable support to render it portable for transport to different job sites.Type: GrantFiled: July 5, 1978Date of Patent: November 27, 1979Inventor: Albert H. Sloan

Patent number: 4083775Abstract: A screening device suitable for cleaning railroad ballast which has become fouled with use, and of the type in which ballast to be cleaned is fed into a screen member to separate the coarse or ballast stone from the fines, the stone being reused to ballast the track. A screen member of generally frusto-conical shape, open at each end, is rotatably mounted on a track running frame, with the axis of the screen extending substantially parallel to the track and either horizontal or slightly inclined to the horizontal. The screen member is rotated so that centrifugal action results in the fouled ballast, loaded into the narrower open end of the screen member, moving up the walls thereof to its larger open end. The fines pass through the screen member and the stone is collected at a stone receiving member located adjacent the wide end of the screen member.Type: GrantFiled: March 5, 1976Date of Patent: April 11, 1978Assignee: Canron, Inc.Inventors: John Kenneth Stewart, Helmuth VON Beckmann
