Claim 1
Independent Claim
214 words
An apparatus responsive to inertial forces from a reference means for releasing an escapement comprising: a weight; a coil extension spring attached to said weight; means for mounting said spring to said reference means such that said weight rests upon said spring, and said weight being movable in at least all directions in a plane transverse of the axis of said spring; cable means attached to said weight, said cable means being reciprocally movable in response to at least non-axial oscillatory movement of said weight; and escapement means, said escapement means comprising first lever means attached to said cable means, said first lever means being mounted on a pivot, catch means, said catch means comprising a first stop means, and a second lever means, said second lever means being operative to rest against said stop means in a first position, said first lever means being movable between said first position and a second position, wherein said second position releases for movement said second lever arm from said first stop means; wherein the distance between said mounting means and said weight is adjustable and wherein the length of said spring means is adjustable for adjusting resonant response frequency of said weight and spring to respond to oscillatory inertial movement in a selected predefined frequency range.
Claim 2
Independent Claim
214 words
An apparatus responsive to inertial forces from a reference means for releasing an escapement comprising: a weight; a coil extension spring attached to said weight; means for mounting said spring to said reference means such that said weight rests upon said spring, and said weight being movable in at least all directions in a plane transverse of the axis of said spring; cable means attached to said weight, said cable means being reciprocally movable in response to at least non-axial oscillatory movement of said weight; and escapement means, said escapement means comprising first lever means attached to said cable means, said first lever means being mounted on a pivot, catch means, said catch means comprising a first stop means, and a second lever means, said second lever means being operative to rest against said stop means in a first position, said first lever means being movable between said first position and a second position, wherein said second position releases for movement said second lever arm from said first stop means; wherein the distance between said mounting means and said weight is adjustable and wherein the length of said spring means is adjustable for adjusting resonant response frequency of said weight and spring to respond to oscillatory inertial movement in a selected predefined frequency range.
Claim 3
Dependent Claim
39 words
The apparatus according to claim 1 wherein said catch means comprises a bearing mounted to said first stop means and rotatable about an axis transverse of motion of said first lever means for minimizing friction in said catch means.
Claim 4
Dependent Claim
27 words
The apparatus according to claim 1 wherein said weight and said spring are insensitive to oscillatory inertial movement of said reference below a predetermined threshold of force.
Claim 5
Dependent Claim
26 words
The apparatus according to claim 3 wherein said weight and said spring are adjustable in length for resonance with oscillatory inertial movement at a preselected frequency.
Claim 6
Dependent Claim
96 words
The apparatus according to claim 1 further including a third lever means mounted to a base pivot means, said third lever means including a second stop means at a position extended from said base pivot means for encountering said second lever means closely adjacent to the pivot of said second lever means for obtaining a mechanical advantage with respect to the end of said second lever means when said second lever means is resting against said first stop means, said third lever means being biased to urge said second lever means against said first stop means.
