One leg terminates in a hanger having the form of a J-shaped hook and the other leg terminates in a protruding eyelet sized to engage a tang at the end of the spring. The two hooks are maintained at approximate right angles with respect to each other to distribute the forces more evenly in the coil spring to avoid spring bowing.

  • Patent number: 6120014
    Abstract: A twist-correcting device for a wire rope isolator, the retaining bars of which may become twisted in the process of installing the conventional wire rope isolator between a platform and an apparatus, which makes it difficult to assemble the wire rope isolator and prevents the isolator from performing fully. The twist-correcting device includes a pair of clamps for correcting the twisting of the retaining bars of the isolator by holding the retaining bars closely parallel to each other at both end portions of the wire rope isolator. The twist-correcting device is capable of simplifying the installation of a wire rope isolator between a platform and an apparatus and enabling the wire rope isolator to perform at its best.

  • Patent number: 6098970
    Abstract: A spring having a helical body with opposed ends and two flexible safety cables each of which is coupled to one of said opposed ends, with the two flexible cables extending in opposite directions pass the center of the helical body, terminating in an attachment thereto. The helical body includes a plurality of coils with one end of each of the cables being coupled to one of the plurality of coils. The attachment includes an elliptically shaped journal through which one of the plurality of coils passes, thereby pivotally attaching the cable thereto. In one embodiment, a threaded boss is disposed at each end of the helical body. The threaded boss has a plurality of recesses, each of which is adapted to receive on of the plurality of coils. In this fashion, the threaded boss threadably engages the helical body.

  • Patent number: 5823518
    Abstract: A spring guide retainer is provided for preventing buckling of a spring during spring compression as an upper die moves toward a lower die in a stamping operation. The spring guide retainer comprises a spring guide housing to hold the spring location, a spring guide holder fixed to the upper die to promote spring alignment, and a spring guide pin to maintain alignment of the spring. A screw associated with the spring guide pin is receivable through a pocket of the spring guide housing to secure the spring guide pin and the spring guide housing to the pad.

  • Patent number: 5433687
    Abstract: According to one aspect of the invention, a free-weight exercise apparatus is provided that includes a left standard and a right standard that are removably joined in spaced-apart relationship by a cross connector. The left and right standards are preferably generally triangular in shape. According to another aspect, an apparatus is provided for assisting a person with dead-lift type exercises. The apparatus includes left and right lifter assemblies, each of which has an upper bar and a lower bar, the bars being maintained in a parallel, spaced-apart relationship by two vertically oriented piston-cylinder units. A spring is positioned co-axially around each of the piston-cylinder units. One of the ends of one of the two piston-cylinder units of each assembly is pivotally connected to one of the bars and the other ends of the two piston-cylinder units are rigidly connected to the bars, whereby binding of the piston-cylinder units is prevented.

  • Patent number: 5390903
    Abstract: A variable force die spring is disclosed which combines high force, short axial compression distance spring assembly, such as belleville springs, and low force, high axial compression distance springs, such as coil springs, in a telescoping casing having an internal cavity. The springs are arranged within the cavity so that upon receiving a load the low force spring will compress first resulting in a large axial compression and low force resistance. The load applied to the telescoping casing will then transition from the low force spring to the high force spring. The high force spring then compresses as the load continues to be applied. In alternative embodiments, a third intermediate spring is added that compresses moderate distances under moderate pressure thereby increasing the overall axial compression and load capacity capabilities of the spring assembly.

    Abstract: This is an all-plastic protective sleeve for the needle of a medical device. It comprises, a plastic base carrying a bottom end of the needle; a plastic end-cap slidably mounted on the needle adjacent a tip end thereof; a plurality of longitudinal plastic slats extending from the base to the end-cap; a cylindrical plastic locking collar disposed over the plurality of longitudinal slats adjacent the end-cap; and, a plastic spring disposed over the plurality of longitudinal slats between the base and the end-cap. The spring is a unitary plastic helical compression spring comprising a cylindrical collar portion disposed over a center portion of the plurality of longitudinal slats with first and second portions of helical compression spring turns extending therefrom toward the base and the locking collar, respectively. The locking collar has an outside diameter larger than the outside diameter of the spring and is of a thickness sufficient to produce a textured grippable area at the periphery thereof.
