The endless belt, 26, formed of filtering material,and the linked conveyor chain, 19, pass respectivelyover the drums, 22, 27, 18, 30, in the direction. shown by the arrows. On coming into contact, asthey leave the drums, 27, 30, they form together acontinuous series of filter-cells enclosed by thelinks of the chain. These pass tlirough thestuffing-box, 40, and the pressure-box, 43, into thefilter-chamber, 49, into which the material to befiltered is introduced through the pipe, .54. Theliquid passes through the band of filter cloth andthrough the perforated supporting plate, 51, andis discharged through the pipe, 55. The residue iscarried by the chain and belt through the pressure-box, 56, and the wa-shing chamber, 57, and thesolid residue is discharged as the band passes overthe drum, 22, any remaining particles being re-moved by tlie brush, 13. The band and the con-veyor chain are washed in the washing boxes,69,64, respectively, on their way back to the drums,27, 30.—W. H. C. Filters ; Plate E. Simoneton. Fr Pat. 473,187, Sept. 10, 1913.
