Patent ID: 8584403

Claim:
A scavenger system with a face plate framework to expel solids from a fluid flow channel comprising: (a) a structure for support of said channel and said scavenger system; (b) said channel supported by said structure for conveyance of fluid; (c) said scavenger system comprised of a scavenger assembly disposed lengthwise within said channel, for scavenging engagement with said channel; (d) an actuator means comprised of a reciprocal expansible chamber device, pivotally connected to said structure for pivotal movement thereof while scavenging; (e) said scavenger assembly further including a face plate framework; (f) said face plate framework attached to said actuator means, and being propelled by said actuator means to expel solids from said channel; (g) said face plate framework further comprised of a face plate, a rear plate, and an end cap forming a box shaped structure to better distribute resultant shear stresses within said framework, while said framework traverses said channel, thereby improving said scavenger performance by reducing twist thereof; and (h) said scavenger assembly including a bearing surface for contacting with said channel for support and friction reduction between said scavenger assembly and said channel.
