Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
108 words
A flexible motion transmitting remote control assembly comprising: flexible conduit means, a motion transmitting core element supported for axial movement within said conduit means, antifriction means for engaging said core element for facilitating movement thereof, retainer means for retaining said antifriction means, and a race member disposed between said antifriction means and said conduit means; said race member including a race portion engaging said antifriction means and spring-acting resilient means reacting between said conduit and said race portion for urging said race portion transversely with respect to the direction of movement of said core element toward said antifriction means thereby urging said antifriction means toward said core element.
Claim 2
Dependent Claim
108 words
A flexible motion transmitting remote control assembly comprising: flexible conduit means, a motion transmitting core element supported for axial movement within said conduit means, antifriction means for engaging said core element for facilitating movement thereof, retainer means for retaining said antifriction means, and a race member disposed between said antifriction means and said conduit means; said race member including a race portion engaging said antifriction means and spring-acting resilient means reacting between said conduit and said race portion for urging said race portion transversely with respect to the direction of movement of said core element toward said antifriction means thereby urging said antifriction means toward said core element.
Claim 3
Dependent Claim
42 words

Claim 6
Dependent Claim
24 words
An assembly as set forth in claim 4 wherein a substantial portion of said return bends are in direct contact with said conduit means.
Claim 7
Dependent Claim
14 words
An assembly as set forth in claim 5 wherein said race portion is arcuate.
Claim 8
Dependent Claim
19 words
An assembly as set forth in claim 6 wherein said return bends are generally parallel to said race portion.
Claim 9
Dependent Claim
