20140265158 | Drain Seal - A sealing assembly for fluidly sealing a roof drain within a conductor pipe has a sealing element and an expansion ring. The sealing element defines an inner wall with a portion that transitions inward and may be disposed on a portion of the roof drain. The expansion ring is disposed within the inner wall. Reciprocation of the of the expansion ring along the inward transitioning portion of the inner wall causes the sealing element to expand outwardly to a sealed position with the sealing element outer wall abutting the conductor pipe inner wall in a fluid tight seal. Opposite reciprocation of the ring allows the sealing element to contract and release from the conductor pipe. | 09-18-2014 |
20140021236 | Installation Tool for Universal Fastener - A tool for installation of a concealed fastener which may be formed in situ during attachment of a first grooved sheathing member to an underlying support member. The tool has a barrel for holding a fixing member axially and a feeding mechanism for holding and advancing cross members and maintaining a cross member aligned with the fixing member in the barrel. The tool allows insertion of a front end of the cross member into a plank groove whereupon a fixing member may be driven from the barrel through the cross member and partially into a support, thereby securing the plank to the support. The feeding mechanism thereafter advances an uninstalled cross member to the forward position aligned with a fixing member. | 01-23-2014 |

20130340377 | Hidden Decking Fastener - A hidden fastener for use in assembling a decking structure by attaching a series of grooved deck planks to underlying joists is disclosed. The fastener is configured with a horizontal body between a leading arm and trailing leg. The leading arm transitions to a leading wing while the trailing leg transitions to a trailing foot. At least one prong extends from the body at a downward angle. The leading wing and trailing foot are configured optimally for engagement within the grooves of adjacent deck planks. The body defines a hole for receipt of an elongated securing member that can be driven therethrough, optionally by a power driving tool, to attach the fastener to an underlying joist. The fastener spaces adjacent decking planks an optimal distance for drainage while providing improved resistance to lateral plank movement caused by thermal expansion or physical forces. | 12-26-2013 |
