Abstract
Abstract A two-piece swage socket is made up of interconnected shank and pin receiving sections. The shank section is made of steel having a spheroidize annealed microstructure. One end of this shank section is initially provided with an outwardly open, axially aligned, cylindrical cup portion, while the other end is constituted as an axially aligned, open, hollow cylinder adapted to be cold swaged upon a wire rope. The swage pin receiving section is made of steel having a substantially harder and stronger microstructure, and one end of it is constituted as a part spherical ball portion integrally connected through a narrowed neck either to a pin receiving clevis or tongue end piece at the other end. To make up the swage socket, the ball portion of the pin receiving section is inserted into the cup of the shank section and the outer end region of the cylindrical cup is cold formed onto the ball portion to provide a connection between the shank section and the pin receiving section such that these parts can be rotated and oscillated one with respect to the other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
A swage fitting for connecting a wire rope to a working element to be permanently rotatably and pivotally supported with respect to said element, said fitting including: A. a hollow shank section of material suitable for cold swaging onto a wire rope, said shank section being provided with: 1. a hollow shank portion adapted to receive a wire rope; and 2. a cup portion integral with and axially aligned with the axis of said shank portion; B. a working section of material which is substantially harder and stronger than the material of the shank section and including a part spherical ball portion having an exterior surface generally corresponding to the interior surface of said cup portion, said ball portion thereby permanently rotatably and pivotally supported within said cup portion; and C. means cooperating with said working section for connecting said working section to said working element.
Claim 2
Dependent Claim
146 words
A swage fitting for connecting a wire rope to a working element to be permanently rotatably and pivotally supported with respect to said element, said fitting including: A. a hollow shank section of material suitable for cold swaging onto a wire rope, said shank section being provided with: 1. a hollow shank portion adapted to receive a wire rope; and 2. a cup portion integral with and axially aligned with the axis of said shank portion; B. a working section of material which is substantially harder and stronger than the material of the shank section and including a part spherical ball portion having an exterior surface generally corresponding to the interior surface of said cup portion, said ball portion thereby permanently rotatably and pivotally supported within said cup portion; and C. means cooperating with said working section for connecting said working section to said working element.
Claim 3
Dependent Claim
85 words
a cup portion integral with and axially aligned with the axis of said shank portion; B. a working section of material which is substantially harder and stronger than the material of the shank section and including a part spherical ball portion having an exterior surface generally corresponding to the interior surface of said cup portion, said ball portion thereby permanently rotatably and pivotally supported within said cup portion; and C. means cooperating with said working section for connecting said working section to said working element.
Claim 4
Dependent Claim
85 words
a cup portion integral with and axially aligned with the axis of said shank portion; B. a working section of material which is substantially harder and stronger than the material of the shank section and including a part spherical ball portion having an exterior surface generally corresponding to the interior surface of said cup portion, said ball portion thereby permanently rotatably and pivotally supported within said cup portion; and C. means cooperating with said working section for connecting said working section to said working element.
Claim 5
Dependent Claim
25 words
The combination as specified in claim 1 wherein said shank section is made of steel which has been annealed to provide a spheroidize annealed microstructure.
Claim 6
Dependent Claim
36 words
The combination as specified in claim 2 wherein said working section is made of steel which has been heat treated to attain substantially greater hardness and strength than that of the steel in the shank section.
Claim 7
Dependent Claim
20 words
The combination as specified in claim 3 wherein the chemical composition of the steel in both sections is the same.
Claim 8
Dependent Claim
26 words
The combination as specified in claim 3 wherein said shank section is heat treated annealed to have a Brinell hardness number of not over 163 maximum.
Claim 9
Dependent Claim
25 words
The combination as specified in claim 5 wherein the working section is heat treated to have a Brinell hardness number of between 267 and 302.
Claim 10
Dependent Claim
45 words
The combination as specified in claim 3 wherein said shank section is constituted as an alloy steel from the group including the AISI type 3100 series, the 4000 series, the 4100 series, the 4300 series, the 4600 series, the 4700 series and the 4800 series.
