Abstract
Abstract A mechanism for translating linear movement to rotary movement comprising a contact ring integrally interconnected with a toothed ring spaced therefrom by a plurality of helical springs. A driven member engages the toothed ring which is preferably of a bellows construction so that movement of the contact ring toward the toothed ring causes a diametrical dimension change and facilitates rotation of the toothed ring and engagement thereof with the driven member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
A mechanism for translating linear movement to rotary movement comprising a contact ring upon which a linear force can be applied in the direction of the axis of said ring, a toothed ring spaced from said contact ring, a plurality of spaced helical springs integrally interconnecting said contact ring and said toothed ring, and a driven member engaging said toothed ring, and means mounting said driven member for rotation about an axis.
Claim 2
Dependent Claim
72 words
A mechanism for translating linear movement to rotary movement comprising a contact ring upon which a linear force can be applied in the direction of the axis of said ring, a toothed ring spaced from said contact ring, a plurality of spaced helical springs integrally interconnecting said contact ring and said toothed ring, and a driven member engaging said toothed ring, and means mounting said driven member for rotation about an axis.
Claim 3
Dependent Claim
16 words
A mechanism according to claim 1, including means moving said contact ring toward said toothed ring.
Claim 4
Dependent Claim
15 words
A mechanism according to claim 2, wherein said toothed ring is of a bellows configuration.
Claim 5
Dependent Claim
43 words
A mechanism according to claim 3, wherein said contact ring is of greater diameter than said toothed ring so that movement of said contact ring toward said toothed ring causes rotation of said toothed ring and contraction thereof into engagement with driven member.
Claim 6
Dependent Claim
16 words
A mechanism according to claim 3, wherein said driven member is disposed within said toothed ring.
Claim 7
Dependent Claim
44 words
A mechanism according to claim 3, wherein said contact ring is of lesser diameter than said toothed ring so that movement of said contact ring toward said toothed ring causes rotation of said toothed ring and expansion thereof into engagement with said driven member.
