Description: |
| Claim:
The valve wheels for which use of this tool is particularly intended are the widely employed types of wheels generally comprising a substantially circular outer rim connected by means, such as spokes, to a hub which when the wheel is rotated, functions either to open or close a valve. As is known to those skilled in the art, considerable force must oftentimes be employed to tightly close valves to prevent leakages therethrough and, similarly, to open tightly closed valves. Common practice is to use means, such as wrenches, rods, and the like, to engage the hub, spokes and/or rim of the valve wheel in order to apply sufficient force to rotate the wheel, and by using commonly employed means, breakage of the wheel rim, or spokes and the like often occurs necessitating replacement of the valve wheel. |
