Compression spring cramp

Abstract

A compression spring cramp for large helical or coil springs, particularly, axle springs of motor vehicles, comprises, a hollow guide tube with a threaded spindle rotatably mounted in the guide tube. A first spring gripper member has an inner portion secured to the hollow guide tube adjacent the top thereof and has a substantially semi-cylindrical spring engaging channel portion which extends outwardly from the inner portion and has a channel opening extending downwardly so as to be engageable over the coil of the spring. A second gripper has an inner slider portion which is threadedly engaged on the threaded spindle for movement upwardly and downwardly on the guide tube and includes an outer portion with a substantially cylindrical spring engaging channel portion extending outwardly from the slider portion exteriorally of the guide tube and opening upwardly to engage below a coil of the spring. The spindle is rotatable such as by an attached or separately supplied tool which may, for example, comprise a wrench engageable with a hexagonal or squared nut end of the spindle which extends outwardly of the guide tube or by a fluid pressure driven rotor which is incorporated as an extension of the guide tube and which includes a rotor connectable to the spindle which is driven by fluid pressure such as compressed air.
