Abstract
A helical spring end retainer and tension adjuster is formed by a centrally apertured relatively thin wall shallow cup-like member having a hexagonal nut axially secured in the aperture for threaded engagement with a spring surrounded rod.
Claims8
A retainer for a helical spring having opposite ends and surrounding a rod having threaded end portions, comprising:
- a cup-like member having a planar bottom and a marginal edge and a centrally located aperture and having a side wall,
- said side wall being formed from relatively thin material when compared with the diameter of said member,
- the marginal edge of said bottom wall adjacent the aperture being axially offset with respect to the plane of the bottom wall a distance substantially equal with the thickness of the bottom wall;
- and,
- a nut having screw threads and having a diametrically reduced end portion forming an annular shoulder intermediate its ends seated on said bottom wall marginal edge and extending through and secured in the aperture forming the bottom wall aperture.

A retainer for a helical spring having opposite ends and surrounding a rod having threaded end portions, comprising:
- a centrally apertured plate including a cup-like member having a planar bottom, a marginal edge and a centrally located aperture and having a side wall,
- the marginal edge of said plate adjacent the aperture being axially offset with respect to the plane of the plate for forming an annular shoulder adjacent the aperture;
- and,
- a nut having screw threads and having a diametrically reduced end portion forming an annular shoulder intermediate its ends seated on said plate shoulder and extending through and secured in the aperture forming the bottom wall aperture.
