The second working member has its own claw element at one end and a spike element at the other end. A flat bar element is affixed perpendicularly to the cross bar element between its two ends. The firefighting tool is configured to be used in a variety of firefighting applications, allowing the firefighter to carry a single tool rather than a multitude of tools performing different functions. | 05-26-2011 |
20120192360 | LATH AND PLASTER REMOVAL TOOLS AND SYSTEMS - A tool and system for lath and plaster removal. The lath and plaster removal tool is a specialty multi-purpose demolition tool device designed specifically for prying lath and plaster off of walls and ceilings. This tool facilitates the fast and easy removal of both materials at the same time, while also keeping the items separate for easy cleanup. The product is ideal for use by contractors, homeowners, and individuals who wish to remove lath and plaster in buildings. Using this tool of the present invention allows consumers to remove the material in greater quantities, as well as enables them to pry the material off in line with the wall studs, making the process much simpler. The tool may be used in other construction and demolition operations. | 08-02-2012 |
20120216352 | MULTI-FUNCTION TOOL FOR PRYING AND LEVERAGE-ENHANCED GRIPPING - A multi-function tool is disclosed which provides prying as well as leverage-enhanced gripping capability. By combining the lever arm of a prying bar with the gripping capability of gripping pliers, this multi-function tool provides leverage-enhanced gripping and leveraged-forced movement of objects. The lever action of the prying bar can be applied via the gripping pliers, thereby allowing a user to exert more force via the gripping pliers than is possible by using gripping pliers alone. In some embodiments, the prying bar is a crowbar, and the gripping pliers are vice grips. In preferred embodiments, the prying bar and the gripping pliers are welded together. | 08-30-2012 |
