ABSTRACT:
A spring compressor for axially compressing a helical coil spring of an automobile and then holding the spring in the compressed position consists of two identical devices mounted on opposite sides of the axial spring which is to be axially compressed. Each device comprises metal plates held together by rollers, the plates having curved hook formations to engage a coil of the spring. A threaded spindle fits into a housing capable of pivoting between these metal plates. A chain is threaded around the coils of the spring which is to be compressed and around the rollers between the metal plates. Threaded on the spindle is a chain adjustment piece through which the chain passes and which moves outwardly along the spindle when the spindle is turned, so as to cause the chain to pull the spring and compress the coils of the spring between the loop of chain and the curved hook formations of the metal plates. A pin inserted in the chain adjustment piece locks the chain in the required position so as to prevent the chain from sliding through the chain adjustment piece, thus maintaining the spring in its compressed position.
