Abstract
A hand tool for the manipulation of coil springs includes a handle and a shank portion fixedly secured thereto at one end thereof, the free or other end of the shank being integrally provided with a coil spring hook-type engaging portion disposed perpendicularly to the shank portion such that such components, when viewed together, form, in effect, a substantially L-shaped tool bit. The dimensions of the shank and hook portions, as viewed along three mutually orthogonal axes, is substantially the same and are of such a value as to permit the tool to be inserted and properly disposed within the central coil portions of a coil spring.

A hand tool useful for the assembly and disassembly of a coil spring securing a sealed beam headlight within an automotive headlight assembly wherein the space between said sealed beam and a wall of said assembly is at least approximately 0.125 inches, said tool comprising:
- a handle;
- shank means secured at one end thereof to said handle;
- elongated hook means integrally secured to the other end of said shank means and disposed perpendicular to the longitudinal axis of said shank means so as to form therewith a substantially L-shaped member,
- said shank means having a thickness of about 3/32 inch in the vicinity of said hook means and said hook means having a length of about 9/16 to 13/16 inch and a thickness of about 3/32 inch, said dimensions permitting the insertion of said hook means and said other end portion of said shank means between the central coils of a coil spring and within the interior of said spring, said dimensions permitting the manipulation and rotation of said shank means within said coil spring and insertion between a sealed headlight and a wall of said assembly which is about 0.125 inch wide;
- and
- said hooked means further comprising inclined surface portion means for facilitating said insertion of said hooked portion between said spring coils and within the interior portion of said spring and recess means defined between said inclined portion of said hook and said shank member for receiving one of said coils of said spring upon insertion of said hook portion into the interior of said spring.
