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: 9795993Abstract: A screening or screen for use in classifying material. The screening includes a plurality of warp screening elements. Preferably, the plurality of warp screening elements is a plurality of warp wires. The plurality of warp screening elements includes a first warp screening element having a plurality of horizontal undulations. The plurality of warp screening elements further includes a second warp screening element. Preferably, one of the first warp screening element and the second warp screening element is a shaped wire having two substantially flat sidewalls. At least one retaining member is operably associated with the plurality of warp screening elements to form an integral screen segment having a plurality of openings for permitting material to be classified to pass through the openings. The first warp screening element has a cross-sectional height or shape different from the cross-sectional height or shape of the second warp screening element.Type: GrantFiled: February 27, 2014Date of Patent: October 24, 2017Assignee: Lumsden CorporationInventors: Jeffrey L.

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.

Patent number: 9375757Abstract: A screen system having a plurality of screen elements that can be readily removed and replaced to vary one or more characteristics of the screen surface formed by the screen system. The screen system includes a support system for supporting at least one screen element to prevent deformation of the screen element that typically would occur due to the insufficient structural stability of the at least one screen element relative to the weight of the product being screened. Preferably, the support system includes one or more support elements that can be readily and easily installed and removed from the screen system. The support system is preferably configured to permit the one or more support elements to be positioned at different locations in the screen system. Preferably, the support system is configured to permit a variety of different support elements to be used to allow a greater variety of screen elements to be used.Type: GrantFiled: August 11, 2014Date of Patent: June 28, 2016Assignee: Lumsden CorporationInventor: Myron Henry Wardell, Jr.

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.
