Abstract
Abstract A method of forming a universal flexural assembly having resiliency apertures disposed coincident with perpendicular axes of universal motion and freedom of motion spaces respectively disposed about and concentric with said apertures comprising the steps of providing an integral body with freedom of motion chambers and said resiliency apertures therein, inserting resilient coupling members within said resiliency apertures, and removing excess material from said body to transform said freedom of motion chambers into said freedom of motion spaces. The flexural assembly made according to the method disclosed herein is capable of executing virtually loss-free rotational universal movement about two perpendicularly disposed axes while torque may be simultaneously and uninhibitedly transmitted through the assembly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A method of making a universal flexural assembly comprising: forming an integral body having a central portion and two substantially axially extending yoke portions, said central portion having first and second generally U-shaped chambers orthogonally and inversely disposed relative each other, said central portion having first and second generally cylindrical bores orthogonally disposed such that they intersect at their respective centers, said central and yoke members held together by a plurality of support arms; providing a plurality of resilient coupling members within said first and second cylindrical chambers; and removing said support arms such that universal relative movement of said first and second yoke portions occurs in response to a force on one of said yoke portions.
Claim 2
Independent Claim
117 words
A method of making a universal flexural assembly comprising: forming an integral body having a central portion and two substantially axially extending yoke portions, said central portion having first and second generally U-shaped chambers orthogonally and inversely disposed relative each other, said central portion having first and second generally cylindrical bores orthogonally disposed such that they intersect at their respective centers, said central and yoke members held together by a plurality of support arms; providing a plurality of resilient coupling members within said first and second cylindrical chambers; and removing said support arms such that universal relative movement of said first and second yoke portions occurs in response to a force on one of said yoke portions.
Claim 3
Dependent Claim
51 words
The method as claimed in claim 1 wherein said resilient coupling members are provided by stamping a plurality of flexural members from resilient stock; assembling said flexural members along substantially perpendicular planes; positioning a plurality of quadrant members about said flexures circumferentially; and brazing said quadrant members to said flexural members.
Claim 4
Independent Claim
67 words
A method of making a universal flexural assembly comprising: casting an integral body having a central portion and two force application portions extending therefrom; electroetching two generally U-shaped portions from said central portion leaving a plurality of support arms; forming two orthogonally disposed and intersecting bores within said central portion concentric to said U-shaped portions; encasing resilient coupling members within said bores; and removing said support arms.
Claim 5
Independent Claim
67 words
A method of making a universal flexural assembly comprising: casting an integral body having a central portion and two force application portions extending therefrom; electroetching two generally U-shaped portions from said central portion leaving a plurality of support arms; forming two orthogonally disposed and intersecting bores within said central portion concentric to said U-shaped portions; encasing resilient coupling members within said bores; and removing said support arms.
Claim 6
Dependent Claim
23 words
The method as claimed in claim 3 including in addition unitizing said resilient coupling members to said bores formed in said central portions.
