| 20110048099 | HAND-TOOL SYSTEM FOR INSTALLING BLIND FASTENERS - A tool for setting blind fasteners is disclosed. A stem of a fastener is engaged by a pulling head and its sleeve is also engaged by the pulling head. In an initial stage, a pump piston compresses fluid in a hydraulic pump, affecting movement of a drawbar and piston in relation to a stationary adaptor connected to the tool, pulling the stem in relation to the sleeve at a fast rate per pump. As the pulling force increases, pressure in the pump triggers a logic system to shift the tool into a high pressure mode, decreasing the effort to complete fastener installation. The logic system resets after each squeeze of the lever, minimizing the number of pumps necessary to complete the installation while keeping effort at a comfortable level. An adjustable pressure relief valve allows the fluid to return to the reservoir chamber, returning the tool to its initial condition. | 03-03-2011 |
| 20080219798 | STEM PLUG MODIFICATIONS IMPROVING WIREDRAW FUNCTIONALITY - A blind rivet which includes a stem, a sleeve and a locking collar. The stem includes a head or plug portion, and the plug portion includes one or more grooves or depressions which provide that lower installation forces can be used to install the blind rivet, and if a sealant or paint is used, provide a type of escape mechanism for the sealant or paint to travel to during installation of the blind rivet. The grooves or depressions may vary in number and take on any number of shapes and sizes. For example, they may be longitudinal and may get wider and/or deeper toward the end of the stem. | 09-11-2008 |
