Abstract
A leverage handle tool includes a handle and a seat block. In use, a slot in the seat block is located upon a handle such as a vice handle, and the tool is pulled toward the handle end. As the tool is pulled toward the handle end the slot grips the handle due to the frusto-conical configuration thereof. The tool may then be acted upon such that the tool increase the leverage upon handle.

1-7. (canceled)
A hand tool comprising:
- a handle extending along a first axis;
- and
- a seat block mounted to an end of said handle, said seat block having an outwardly opening slot with an open face, said slot being centered around a second axis that is generally parallel but offset from said first axis, and said open face of said slot being configured to be movable downwardly onto a shaft of a vice, and to be moved along the shaft until said seat block abuts an enlarged portion on the shaft, such that said handle can then be utilized to apply torque to said shaft with an elongated lever arm due to the attachment of said handle to the shaft.
A combination of a vice and a handle comprising:
- a vice having a shaft extending along an axis to an enlarged portion;
- a hand tool received to create an elongated lever arm to allow increased torque to turn said shaft, said hand tool comprising a handle extending along a first axis, and a seat block mounted to an end of said handle, said seat block having an outwardly opening slot with an open face, and said open face of said slot being configured to be movable downwardly onto the shaft, and to be moved along the shaft until said seat block abuts the enlarged portion on the shaft, such that said handle can then be utilized to apply torque to the shaft with an elongated lever arm due to the attachment of said handle to the shaft.
A method of increasing leverage on a vice handle comprising the steps of:
- (1) providing a vice shaft extending to an enlarged portion;
- (2) moving a hand tool onto said vice shaft such that an open slot in a seat block is moved onto said vice shaft, and said open slot is then brought to abut said enlarged portion of said vice shaft with a tool handle extending from said seat block, and beyond said enlarged portion;
- (3) applying a torque to said tool handle, such that said torque is transferred to said vice shaft through said slot.
