Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
A resettable fire link comprising, (a) a releasable member; (b) gripping means associated with said releasable member for engaging said releasable member in a normal position, and for releasing said releasable member in an actuated position, said gripping means comprising at least one mounting element and heat responsive means for causing said gripping means to move to the normal position in response to a preselected ambient temperature and for causing said gripping means to move to the actuated position in response to a preselected increase in said ambient temperature; and (c) mechanical activation means associated with said mounting element for movement from a first withdrawn to a second extended position, said mechanical activation means in said first withdrawn position allowing said gripping means to move between said normal and said activated position and for causing said gripping means to move to the activated position in response to movement of said mechanical activation means to said second extended position.
Claim 2
Dependent Claim
158 words
A resettable fire link comprising, (a) a releasable member; (b) gripping means associated with said releasable member for engaging said releasable member in a normal position, and for releasing said releasable member in an actuated position, said gripping means comprising at least one mounting element and heat responsive means for causing said gripping means to move to the normal position in response to a preselected ambient temperature and for causing said gripping means to move to the actuated position in response to a preselected increase in said ambient temperature; and (c) mechanical activation means associated with said mounting element for movement from a first withdrawn to a second extended position, said mechanical activation means in said first withdrawn position allowing said gripping means to move between said normal and said activated position and for causing said gripping means to move to the activated position in response to movement of said mechanical activation means to said second extended position.
Claim 3
Dependent Claim
36 words
The invention of claim 1 wherein said heat responsive means moves said mechanical activation means from the extended to the withdrawn position in response to said ambient temperature and the deactivation of said mechanical activation means.
Claim 4
Dependent Claim
37 words
The invention of claim 1 wherein said heat responsive means further comprises a bimetallic element, and wherein said mechanical activation means is associated with said mounting element to selectively separate said mounting element from said bimetallic element.
Claim 5
Dependent Claim
59 words
The invention of claim 3 wherein said mechanical activation means further comprises force producing means and a ram, said force producing means being disposed on the opposite side of said mounting plate from said bimetallic element, and least a portion of said ram being disposed through a void defined in said mounting element for engagement with said gripping means.
Claim 6
Dependent Claim
14 words
The invention of claim 4 wherein said force producing means comprises a pneumatic cylinder.
Claim 7
Dependent Claim
22 words
The invention of claim 5 wherein said cylinder is spaced apart from said mounting element, whereby an air passage is created therebetween.
Claim 8
Dependent Claim
61 words
A releasing device comprising: (a) a first element; (b) a heat actuated bimetallic second element coacting with said first element to separate from said first element in response to temperature change; and (c) pneumatic means associated with said first element for selectively separating said first and second elements without interfering with said separation of said elements in response to temperature change.
Claim 9
Dependent Claim
61 words
A releasing device comprising: (a) a first element; (b) a heat actuated bimetallic second element coacting with said first element to separate from said first element in response to temperature change; and (c) pneumatic means associated with said first element for selectively separating said first and second elements without interfering with said separation of said elements in response to temperature change.
