Abstract
A fusible link assembly including a pair of link members arranged in overlying relation and a thermally sensitive bonding material interposed between the link members with the bonding material being solid below a predetermined temperature to form a bond between the link members and liquid at and above the predetermined temperatures such that the link member separates. Each of the link members includes a projection and a slot corresponding to the projection. The slot is spaced relative to the projection on the link member such that the projection of one of the link members is received in the slot of the other link member. Each of the link members also includes an opening with each opening on each of the link members being aligned to define a passage through the fusible link.
Claims18
A fusible link assembly comprising:
- a pair of link members arranged in overlying relation with each link member opposed diametrically with respect to the other and a thermally sensitive bonding material interposed between said link members, said bonding material being solid below a predetermined temperature to form a bond between said link members and liquid at and above said predetermined temperature such that said link members separate;
- each of said link members including a projection and a slot corresponding to said projection, said slot spaced relative to said projection on said link members such that the projection on one of said link members is received in nesting relation in the slot of the other said link members and such that the cooperation of said projection and slot inhibits creep between said pair of link members;
- and
- each of said link members including an opening located between said projection and said slot with each opening on each of said link members being aligned to define a passage through said fusible link and to promote air flow through said fusible link thereby improving heat transfer between the ambient air and said fusible link to increase the responsiveness of said fusible link to ambient temperatures above said predetermined temperature without creep between said pair of link members.
A fusible link assembly comprising:
- a pair of link members arranged in overlying relation and a thermally sensitive bonding material interposed between said link members, said bonding material being solid below a predetermined temperature to form a bond between said link members and liquid at and above said predetermined temperature such that said link members separate;
- one of said link members including a projection and the other of said link members including a slot corresponding to said projection such that the projection of the one link member is received in nesting relation in the slot of the other link member and such that the cooperation of said projection and slot inhibits creep between said pair of link members;
- and
- each of said link members including an opening located between said projection and said slot with each opening on each of said link members being aligned to define a passage through said fusible link and to promote air flow through said fusible link thereby improving heat transfer between the ambient air and said fusible link to increase the responsiveness of said fusible link to ambient temperatures above said predetermined temperature without creep between said pair of link members.
A fusible link assembly comprising:
- a pair of link members arranged in overlying relation and a thermally sensitive bonding material interposed between said link members, said bonding material being solid below a predetermined temperature to form a bond between said link members and liquid at and above said predetermined temperature such that said link members separate;
- one of said link members including a projection, said projection presenting an arcuate outer surface, the other of said link members including a slot corresponding to said projection and presenting at least one flat edge inclined at a predetermined angle .alpha., said projection of said link member received in nesting relation in said slot of the other link member such that said arcuate outer surface of said projection engages said inclined flat edge of said slot and such that cooperation of said projection and said slot inhibits creep between said pair of link members.
