Abstract

This tool spreads at least a portion of a high tension spring by squeezing the handles together by hand thereby separating the arms. This is the opposite of what happens when the handles of standard pliers are squeezed together.
Claims12
A tool for spreading high tension springs comprising a first level and a second level opposed thereto, each level having a handle at the bottom end, an arm at the top end, and an intermediate region at which the levers are hinged to each other by a pivot means having a pivot axis about which the levers pivot, an end of the arm of said first lever having a first means to hold a hook of a helical spring said first means extending perpendicular to said first lever generally in a plane in which said first lever pivots, an end of the arm of said second lever having a second means to hold a separate section of said spring, said second means having a slot cut in its top said slot lying perpendicular to a plane in which said second lever pivots, said second means having a right side and a left side extending above and below the plane in which said second lever pivots;
- the separate section of said spring being stretchable away from said hook, the handle and arm of each lever being on the same side of said pivot means, the arrangement being such that the handles are squeezed together to spread the arms to stretch said spring;
- wherein said second means is detachable from the end of the arm of said second lever having a shank extending towards the end of the arm of said second lever further comprising an extension between the end of the arm of said second lever and said second means, said shank fitting into a non-round hole in said extension which fits into a non-round hole in the end of the arm of said second lever.
