Title: Shock absorber spring changing tool
Claims: I claim: 1. A tool for changing the helical coil spring of a shock absorber, said shock absorber having a removable keeper at one end and a nonremovable keeper at the other end retaining the coil spring, the tool comprising a base of generally rectangular plan form, means adjacent one end of the base for anchoring the nonremovable keeper end of the shock absorber when placed on said base, means adjacent the other end of and in the base for positioning shaft means proximate to said removable keeper, lever means adapted to be positioned over said shaft means and to be pivotable thereabout, and means integral with said lever means for compressing said coil spring as said lever means is rotated about said shaft so as to permit removal of said removable keeper and removal of said spring from said shock absorber. 2. A tool in accordance with claim 1 in which the means for compressing the coil spring is a pair of pins which are inserted between coils of the coil spring when the lever means is positioned over the shaft. 3. A tool in accordance with claim 2 in which the coil spring compressor pins are located on a line above the shaft approximately coincident with the shock absorber center line. 4. A tool in accordance with claim 2 in which the coil spring compressor pins are located so as to be staggered along the length of the coil spring so as to fit conveniently between coils of the spring. 5. A tool in accordance with claim 2 in which the pins are located on a common line approximately on the center line of the shock absorber when in position on the base and displaced with respect to each other along the length of the shock absorber. 6. A tool in accordance with claim 2 in which the base has ends with holes therein for securing the base to a fixed surface. 7. A tool in accordance with claim 1 having safety pin means useable with said anchoring means to retain said shock absorber in place on said base and with said shaft means to retain it in place in said base. 8. A tool in accordance with claim 1 in which there are a plurality of means in the base for positioning the shaft means so as to accommodate shock absorbers of different lengths. 9. A tool in accordance with claim 1 in which the lever means includes a handle and a U-shaped claw having slotted projections fitting over the shaft means. 10. A tool in accordance with claim 9 in which a pin projects from each projection toward the other pin. 11. A tool assembly to be used to change the helical coil spring of a shock absorber, the tool including a base having side elements and end elements forming a box-like structure, supporting means on said base adjacent one end, said supporting means including means for anchoring one end of a shock absorber and means for retaining said shock absorber in place, a plurality of sets of holes in said side elements at different distances from said supporting means, shaft means adaptable to be positioned in one set of said sets of side element holes and having portions extending outward from said side elements, means for retaining said shaft in a set of holes, and lever means positionable on the outward extending portions of said shaft means, said lever means having means thereon for compressing the helical coil spring of a shock absorber. 12. A tool assembly in accordance with claim 11 in which there are holes in the end elements of said base for the attachment of the base to a fixed surface. 13. A tool assembly in accordance with claim 11 in which the lever means has a claw-like portion which surrounds a shock absorber lying on said base with one end connected to said supporting means. 14. A tool assembly in accordance with claim 13 in which the claw-like portion has spring depressing means for fitting between coils of said spring. 15. A tool assembly in accordance with claim 14 in which the spring depressing means are pins extending toward each other from the interior of the claw-like portion and staggered along the coil spring. 16. A tool assembly in accordance with claim 11 in which the retaining means on said supporting means and said shaft means are U-shaped safety pins. Other info: Inventors: Roy, Richard M.
