Abstract
Disclosed herein is an apparatus for installing coil springs about a central longitudinal shaft, as for shock absorbers. The apparatus comprises a lever arm having one end that separates into a fork with two tines. A detachable pin is located at the end of the tines to provide a coupling with the shaft. A shank is mounted pivotally between the tines of the fork. Shoes on either end of the shank are inclined at opposite angles to mate evenly with coils of a spring. Applying force to the lever arm lowers the shoes, compressing the springs and allowing a keeper to be withdrawn.
Claims5
An for installing or removing a compressed coil spring encircling a shaft, comprising:
- a lever arm;
- a fork having two tines formed at the forward end of the lever arm;
- coupling means for coupling the forward ends of the tines with the shaft to form a fulcrum point;
- a shank pivotally attached between the tines and having a portion extending transverse to the longitudinal axis of the lever arm;
- a first shoe affixed to a first end of the shank, projecting forwardly for applying compression to the coil spring, the engaging surface of the shoe being inclined an angle .alpha. with respect to the longitudinal axis of the coupling means for mating evenly with the coils of the spring.
