Patent number: 10029281Abstract: A wire screening for classifying material. The screening may include a plurality of interwoven warp and weft wires where the weft wires are individually coated with a coating that expands and collapses to enhance performance and longevity of the screen. The coating of one or more weft wires may differ in at least one characteristic from the coating of one or more other weft wires. The warp wires can be individually coated to enhance performance and/or longevity of the screening. Binding blocks can be used in place of weft wires. The coating of one or more warp wires may differ in at least one characteristic from the coating of one or more other warp wires and/or one or more weft wires. The screening can include a plurality of uncoated weft and warp wires where the crimp depth of each wire forming each opening has a different crimp depth.Type: GrantFiled: October 19, 2015Date of Patent: July 24, 2018Assignee: Lumsden CorporationInventors: Boyd E. Knepp, Myron Henry Wardell, Jeffery L. Beck

Patent number: 9486837Abstract: A woven wire screening for use in classifying material flowing therethrough and a method of forming the same. The woven wire screening includes a plurality of warp wires and a plurality of weft wires. The plurality of warp wires and the plurality of weft wires are interwoven to form an integral wire cloth having a plurality of openings for permitting material to be classified to flow through the openings. The integral wire cloth includes an upper screening surface configured to enhance the tumbling action of product impacting the upper screening surface to improve throughput of the woven wire screening.Type: GrantFiled: July 19, 2013Date of Patent: November 8, 2016Assignee: Lumsden CorporationInventors: Myron Henry Wardell, Arthur Lumsden, Jeffery L. Beck, Boyd E. Knepp

Patent number: 8973743Abstract: A woven wire conveyor belt having a plurality of spiral wires and a plurality of connecting wires operably associated with the plurality of spiral wires to form a conveying surface with a plurality of openings formed therein. Each of the plurality of spiral wires has a first side wall and a second side wall that are substantially flat. The connecting wires can be crimped or straight wires. The spiral wires can be left spiral wires, right spiral wires or a combination of left and right spiral wires. The spiral wires and the connecting wires are preferably formed from round wire. Preferably, the woven wire conveyor belt is an endless belt. The conveyor belt can be a balanced weave wire belt, a double weave wire belt, a rod reinforced weave wire belt, a chevron weave wire belt, a double balance weave wire belt, and a single weave wire belt.Type: GrantFiled: March 22, 2013Date of Patent: March 10, 2015Assignee: Lumsden CorporationInventors: Glenn Farrell, Gina Mitchell, Boyd E.

Patent number: 8919568Abstract: A screening having a plurality of warp elements. The plurality of warp elements includes first and second warp elements each having a plurality of undulations oriented in any desired manner including but not limited to horizontal or vertical. At least one retaining member is operably associated with the plurality of warp elements to form an integral screen segment having a plurality of openings. The first warp element has at least one characteristic different from the second warp element to prevent blinding of the screen segment. The at least one characteristic affecting movement of the first warp element and the second warp element when the screen segment is used to classify material such that at least one of amplitude and frequency of movement of the first warp screening element is different from that of the second warp element when subjected to the same operating condition.Type: GrantFiled: September 15, 2011Date of Patent: December 30, 2014Assignee: Lumsden CorporationInventors: Jeffrey L. Beck, Myron Henry Wardell, Boyd E. Knepp

The plurality of warp wires and the plurality of weft wires are interwoven to form an integral wire cloth having a plurality of openings for permitting material to be classified to flow through the openings. The plurality of warp wires are crimped to form upper and lower knuckles. The plurality of weft wires are crimped to form upper and lower knuckles. Preferably, the plurality of weft wires are crimped deeper than the plurality of warp wires such that the upper knuckles of the weft wires are higher than the upper knuckles of the warp wires creating a knuckle height differential between the upper knuckles of the weft wires and the upper knuckles of the warp wires.Type: GrantFiled: May 30, 2008Date of Patent: October 19, 2010Assignee: Lumsden CorporationInventor: Boyd E.
