Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
A precision actuating mechanism comprising a stationary shaft, slidably mounted upon said shaft a sequence of interconnected actuating components of predeterminably variable length axially of said shaft having limit stop means for limiting positively their condition of maximum axial length and their condition of minimum axial length, means selectively operable to adjust the axial length of said components individually to either their maximum axial length or their minimum axial length, means holding one end of said sequence of components against movement relative to said shaft, and means supported at the free opposite end of said sequence of components for indicating any changes of the sum total of the axial lengths of said components.
Claim 2
Dependent Claim
113 words
A precision actuating mechanism comprising a stationary shaft, slidably mounted upon said shaft a sequence of interconnected actuating components of predeterminably variable length axially of said shaft having limit stop means for limiting positively their condition of maximum axial length and their condition of minimum axial length, means selectively operable to adjust the axial length of said components individually to either their maximum axial length or their minimum axial length, means holding one end of said sequence of components against movement relative to said shaft, and means supported at the free opposite end of said sequence of components for indicating any changes of the sum total of the axial lengths of said components.
Claim 3
Dependent Claim
119 words
A precision actuating mechanism comprising a stationary shaft, a sequence of mechanically interconnected bellows slidably mounted upon said shaft in end to end relation having limit stop means for positively limiting the axial length of said bellows in their condition of maximum contraction and their condition of maximum expansion, means selectively operable to (adjust) set the axial length of said bellows individually to either their condition of maximum contraction or their condition of maximum expansion, means holding one end of said sequence of bellows positively against movement relative to said shaft, and means supported from the free opposite end of said sequence of bellows for indicating any changes in the sum total of the axial lengths of said bellows.
Claim 4
Dependent Claim
119 words
A precision actuating mechanism comprising a stationary shaft, a sequence of mechanically interconnected bellows slidably mounted upon said shaft in end to end relation having limit stop means for positively limiting the axial length of said bellows in their condition of maximum contraction and their condition of maximum expansion, means selectively operable to (adjust) set the axial length of said bellows individually to either their condition of maximum contraction or their condition of maximum expansion, means holding one end of said sequence of bellows positively against movement relative to said shaft, and means supported from the free opposite end of said sequence of bellows for indicating any changes in the sum total of the axial lengths of said bellows.
Claim 5
Dependent Claim
55 words
An actuating mechanism according to claim 2 wherein said means selectively operable to set said bellows individually to either their conditions of maximum contraction or maximum expansion are pneumatic evacuation lines in combination with spring means operative at the free end of said sequence of bellows to urge said bellows into their fully expanded conditions.
