A spring compressor of the type having a base, a post, upper spring mounting means fixedly mounted on the upper portion of the post, lower spring mounting means slidably mounted on the lower portion of the post, and moving means for moving the lower spring mounting means toward the upper spring mounting means to compress a spring mounted between the spring mounting means. The upper spring mounting means has spring engaging means, preferably in the form of angle iron members, for engaging the top of the spring assembly. The spring engaging means can include stop means for preventing movement of the spring assembly toward or away from the post. In place of the spring engaging means, the spring compressor can have adapters mounted on at least one of the upper and lower spring mounting means to engage portions of the side of a coil of the spring. The adapters can also be combined with the spring engaging means.
Cette invention concerne un outil de compression de ressort constitué d'une base, d'une colonne, d'un dispositif supérieur de fixation de ressort fixé à la partie supérieure de la colonne, d'un dispositif inférieur de fixation de ressort coulissant sur la colonne, et d'un dispositif commandant le déplacement du dispositif de fixation de ressort inférieur vers le dispositif de fixation de ressort supérieur pour comprimer le ressort. Le dispositif supérieur de fixation de ressort comprend un dispositif de retenue, de préférence sous forme de cornières, pour retenir la partie supérieure du ressort. Ce dispositif de retenue peut ou non comporter un élément spécialement conçu pour empêcher le ressort de se rapprocher de la colonne ou de s'en écarter. Le dispositif de retenue peut être remplacé par d'autres éléments rattachés à au moins l'un des deux dispositifs de fixation du ressort et saisissant les spires du ressort sur un côté. Ces éléments peuvent aussi s'ajouter au dispositif de retenue.
