Patent number: 6237459Abstract: A cove base cutting guide tool for guiding a knife through the guide tool and making a mitered cut on a cove base material. The guide tool includes a base and a plurality of tower members extending vertically from the base forming a first and second guide wall. The first and second guide walls define a groove having the same general shape as the cove base material to be cut. The groove includes a generally straight portion extending from a top to a bottom of the first and second guide walls with an open end at the top of the guide walls. The groove is wider at the bottom of the straight portion than the top of the straight portion. The first and second guide walls flex away from one another at the top of the groove when receiving the cove base material, and apply friction to the cove base material at the top of the cove base material when the cove base material is inserted into the groove.Type: GrantFiled: September 22, 1999Date of Patent: May 29, 2001Assignee: Duramax, Inc.Inventor: Charles Brown

Patent number: 5888017Abstract: A resilient expansion joint insert member for insertion into the expansion joint between adjacent concrete floor slabs. As the concrete slabs move further apart due to settling or thermal contraction, insert member covers the widened gap. Likewise, as the concrete slabs move closer together due to settling or thermal expansion, the insert member is compressed and absorbs the force as the slabs move against each other. The flooring material on the slabs near the expansion joint move beneath a cap of the insert member.Type: GrantFiled: September 22, 1997Date of Patent: March 30, 1999Assignee: Duramax, Inc.Inventor: Dawn Corrie
