Abstract
A tool for coiling spring and holding the coiled spring for replacing strip type spring used in equipment such as chain saws, weed cutting implements, etc. The spring is coiled within a cap that has an ejector plate provided therein as well as a spring holder. Once the spring is wound within the cap, the spring holder is moved relative to the cap to release the inner end of the spring and the ejector plate is used for pushing the plate out of the cap into a pull cord starting housing of an internal combustion engine.
Claims7
A tool for coiling a spring and holding said coiled spring for insertion in a housing of an implement comprising:
- a cylindrical spring cap having a downwardly extending flange, a window provided in said downwardly extending flange through which an end of flat spring to be coiled is inserted;
- an inner housing;
- an ejector plate, carried within said cap and supported by said inner housing;
- a hole provided in said ejector plate;
- a spring loaded plunger having an upper end and a lower end, said spring loaded plunger extending through said inner housing;
- a spring holder carried on a lower end of said spring loaded plunger for holding an end of a spring to be coiled when in a first extended position and for releasing said end of said spring to be coiled when retracted to a second position;
- said spring holder extending through said hole in said ejector plate into said cap when in said first extended position;
- a movable housing supporting said cylindrical spring cap;
- a spring forcing said movable housing and said cap downwardly relative to said inner housing holding said ejector plate adjacent a top inner portion of said cap,
- a handle carried by an upper end of said spring loaded plunger for rotating said plunger and said spring holder for drawing said spring to be coiled through said window in said cap and coiling said spring within said cap and for raising said plunger within said cap to said second position to release said coiled spring from said spring holder;
- and
- a gripping surface carried by said movable housing for raising said movable housing and said cap relative to said ejector plate for ejecting said coiled spring from said cap into said housing of said implement.
