Abstract
The present invention relates generally to the field of accessories for use with impact drivers that are useful for removing a valve seat from a fitting. The device has a first end, a second end and a central body portion. The first end has a shaft that allows the device to be attached to the chuck of an impact driver or drill. The second end has a head that can be placed within a valve seat. Once inserted into the valve seat, the impact driver or drill can be used to spin the device to remove the valve seat from the surrounding fixture.
Claims18
A tool for removing a valve seat, the tool comprising:
- a body having a first end, a second end and a central body portion disposed between the first and second ends;
- wherein the first end having an engagement head and a recess adjacent to the engagement head;
- wherein the second end comprises a deformable element for securing the second end in the valve seat;
- and
- further wherein the second end is sized and configured to fit within the valve seat and lock in place so that the second end cannot rotate within the valve seat allowing the valve seat to unthread from a valve housing when the tool is rotated.
An impact drill system comprising:
- an impact drill having an adjustable chuck;
- an accessory for an impact drill, wherein the accessory is used for removing a valve seat;
- the accessory having a first end with an engagement head, wherein the engagement head is configured to fit within the adjustable chuck;
- the accessory having a second end with a diameter that is larger than a diameter of the first end;
- and
- the first and second ends are disposed on opposite ends of a shaft;
- and
- wherein the second end further comprises a plurality of deformable elements spaced along an exterior surface of the second end configured to frictionally engage and lock the second end within the valve seat so that the second end cannot rotate within the valve seat allowing the valve seat to unthread from a valve housing when the accessory is rotated with the impact drill.
An impact drill and tool combination comprising;
- an impact drill having an adjustable chuck;
- and
- a tool having a first end for insertion into the adjustable chuck and a second end for insertion into a valve seat, wherein the first end is comprises of a shaft and the second end is connected to a body having an internal channel, and further wherein the shaft is sized and configured to fit within the internal channel of the body;
- and
- wherein the second end further comprises a LED light disposed on a body of the second end, a rechargeable battery for powering the LED light, and a universal serial bus port for recharging the battery;
- and
- wherein the second end further comprises a plurality of deformable elements spaced along an exterior surface of the second end configured to frictionally engage and lock the second end within the valve seat so that the second end cannot rotate within the valve seat allowing the valve seat to unthread from a valve housing when the accessory is rotated with the impact drill.
