Abstract
Abstract Apparatus for measuring wear on rod end bearings and method of manufacture whereby an indicator pin is mounted in a raceway within the bearing with one end adjacent the spherical ball and the other end extending through a bore in the rod end to protrude above the outer rod end surface. The wear can be determined by placing the rod end in compression to force the spherical ball into contact with the seat opposite the raceway and depressing the protruding pin end manually until a pin end intimately contacts the ball so that the length of the protruding pin end indicates wear. In one embodiment the rod end surface adjacent the protruding pin is formed as a raised reference surface with the pin extending through a recessed portion thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
In combination: a bearing member having an inner bearing surface bounding a journal means receiving space and an outer surface, a raceway adjacent and opening onto said inner surface and a bore extending between said raceway and said outer surface; journal means mounted within said journal receiving space of said bearing and bounded by said inner bearing surface; and an indicator pin having a portion extending in said raceway from one end of said portion which contacts said journal means to a shoulder for holding said pin in said raceway and preventing said portion moving into said bore and an indicator end extending from said shoulder through said bore to a position with respect to said outer surface of said bearing member indicating wear when said seat is in contact with said journal means.
Claim 2
Dependent Claim
134 words
In combination: a bearing member having an inner bearing surface bounding a journal means receiving space and an outer surface, a raceway adjacent and opening onto said inner surface and a bore extending between said raceway and said outer surface; journal means mounted within said journal receiving space of said bearing and bounded by said inner bearing surface; and an indicator pin having a portion extending in said raceway from one end of said portion which contacts said journal means to a shoulder for holding said pin in said raceway and preventing said portion moving into said bore and an indicator end extending from said shoulder through said bore to a position with respect to said outer surface of said bearing member indicating wear when said seat is in contact with said journal means.
Claim 3
Dependent Claim
36 words
In combination as in claim 1 wherein said bearing member includes a reference surface extending adjacent to the opening of said bore onto said outer surface with a recessed portion through which said pin end extends.
Claim 4
Dependent Claim
34 words
In combination as in claim 2 wherein said reference surface comprises a relatively flat surface raised above the rest of the bearing member outer surface and said recessed portion comprises a machined transverse slot.
Claim 5
Dependent Claim
36 words
In combination as in claim 1 wherein said bearing member is a rod end and said bore has an axis coinciding with the axis of the rod and wherein said journal means is a spherical ball.
Claim 6
Dependent Claim
21 words
In combination as in claim 1 wherein said pin end protrudes above said outer surface until allowable wear has been exceeded.
