摘要：A spring compressor for axially compressing a helical coil spring of anautomobile and then holding the spring in the compressed position consists of twoidentical devices mounted on opposite sides of the axial spring which is to be axiallycompressed. Each device comprises metal plates held together by rollers, the plateshaving curved hook formations to engage a coil of the spring. A threaded spindle fits intoa housing capable of pivoting between these metal plates. A chain is threaded around thecoils of the spring which is to be compressed and around the rollers between the metalplates. Threaded on the spindle is a chain adjustment piece through which the chainpasses and which moves outwardly along the spindle when the spindle is turned, so as tocause the chain to pull the spring and compress the coils of the spring between the loopof chain and the curved hook formations of the metal plates. A pin inserted in the chainadjustment piece locks the chain in the required position so as to prevent the chain fromsliding through the chain adjustment piece, thus maintaining the spring in its compressedposition.
