Self-aligning rod end coupler
First Claim
1. A self-aligning rod end coupler, comprising:
- a housing having a first open end and a second open end, said first open end having an internally threaded portion and said second open end having a radially inwardly extending flange;
a female adapter having an externally threaded portion for engaging said internally threaded portion of said first open end of said housing;
a slide washer having a first surface slidably disposed against said radially inwardly extending flange of said second open end of said housing and having a partial, substantially spherical second surface;
a male adapter having a first threaded end and a second end, said second end including a radially outwardly extending portion having a first partial, substantially spherical, concave surface on a longitudinal end of said male adapter and a second partial, substantially spherical, convex surface, said second partial, substantially spherical, convex surface of said second end of said male adapter engaging said partial, substantially spherical second surface of said slide washer; and
a thrust washer disposed between said male adapter and said female adapter, said thrust washer having a partial, substantially spherical, convex surface for engaging said first partial, substantially spherical, concave surface of said second end of said male adapter wherein during rotational movement of said male adapter relative to said housing, said male adapter moves relative to said slide washer and said thrust washer.

Abstract
A self-aligning rod end coupler including an outer housing having a first open end with an internally threaded portion and a second open end having a radially inwardly extending flange. A female adapter is provided having an externally threaded portion for engaging the internally threaded portion of the first open end of the outer housing and an internally threaded portion for engaging an external thread on a rod member. A slide washer is provided having a substantially flat surface disposed against the radially inwardly extending flange in the second open end of the outer housing and having a partial, substantially spherical surface. A male adapter is provided having an externally threaded first end and a second end including a radially outwardly extending portion having a first partial, substantially spherical, concave, surface on a longitudinal end of the male adapter and a second partial, substantially spherical, convex, surface for engaging the partial, substantially spherical surface of the slide washer. A thrust washer is disposed between the male adapter and the female adapter. The thrust washer includes a partial, substantially spherical, convex, surface for engaging the first partial, substantially spherical, concave, surface of the male adapter. The male adapter is both laterally and spherically moveable relative to a central axis of the outer housing.

11. A method of making a self-aligning rod end coupler, comprising the steps of:
-
providing a housing having a first open end and a second open end, said first open end having an internally threaded portion and said second open end having a radially inwardly extending flange; inserting a slide washer in said first open end of said housing, said slide washer having a substantially flat surface and a partial, substantially spherical surface, said substantially flat surface disposed against said radially inwardly extending flange; inserting a male adapter through said first open end of said housing and through an opening in said slide washer, said male adapter having a first externally threaded end and a second end, said second end including a radially outwardly extending portion having a first partial, substantially spherical, concave, surface on a longitudinal end of said male adapter and a second partial, substantially spherical, convex, surface, said second partial, substantially spherical, convex surface of said second end of said male adapter engaging said partial, substantially spherical surface of said slide washer; inserting a thrust washer in said first open end of said housing, said thrust washer having a partial, substantially spherical, convex, surface for engaging said first partial, substantially spherical, concave, surface of said second end of said male adapter; and inserting a female adapter in said first open end of said housing, said female adapter having an externally threaded portion for engaging said internally threaded portion of said first open end of said housing wherein during rotational movement of said male adapter relative to said housing, said male adapter moves relative to said slide washer and said thrust washer. - View Dependent Claims (12, 13, 14)
