Abstract
Abstract A fuse holder adapter for use with knife-blade fuse clips used with standard 600 ampere fuses in which the adapter comprises first and second metallic plates mounted in facing, spaced relationship on an insulator plate. The first and second metallic plates have respective first and third sections which are adapted to receive fuse clips to form fuse holders of different length and further have respective second and fourth sections formed as knife-blades and extending beyond the insulator plate so as to be able to be receivable in the knife-blade fuse clips used with the standard 600 ampere fuses.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
186 words
A multiple fuse adapter for use with first and second predetermined fuse clips spaced at a first predetermined distance from one another, the multiple fuse adapter comprising: first and second metallic plates; an insulator plate; said metallic plates being mounted on said insulator plate such that the metallic plates lie in a plane, separated by a distance sufficient that one edge portion of each metallic plate is engageable with one of said predetermined fuse clips and that the metallic plates are electrically isolated from each other, with a further portion of the edge of one metallic plate facing a further portion of the edge of the other metallic plate, said further edge portions forming a pair of opposing edge portions; a plurality of fuse clip pairs, respective clips of said fuse clip pairs being each affixed to respective ones of the metallic plates such that the clips of at least one of the fuse clip pairs are spaced from each other at a distance different from that separating the clips of another such fuse clip pairs, said fuse clip pairs constituting a plurality of fuse holders.
Claim 2
Dependent Claim
186 words
A multiple fuse adapter for use with first and second predetermined fuse clips spaced at a first predetermined distance from one another, the multiple fuse adapter comprising: first and second metallic plates; an insulator plate; said metallic plates being mounted on said insulator plate such that the metallic plates lie in a plane, separated by a distance sufficient that one edge portion of each metallic plate is engageable with one of said predetermined fuse clips and that the metallic plates are electrically isolated from each other, with a further portion of the edge of one metallic plate facing a further portion of the edge of the other metallic plate, said further edge portions forming a pair of opposing edge portions; a plurality of fuse clip pairs, respective clips of said fuse clip pairs being each affixed to respective ones of the metallic plates such that the clips of at least one of the fuse clip pairs are spaced from each other at a distance different from that separating the clips of another such fuse clip pairs, said fuse clip pairs constituting a plurality of fuse holders.
Claim 3
Dependent Claim
66 words
A multiple fuse adapter in accordance with claim 1 wherein: said first and second predetermined fuse clips are knife-blade receiving fuse clips, and are separated at a distance sufficient to receive standard 600 ampere fuses in existing telephone central office equipment; and said pairs of metallic plates are such that each has one edge portion formed as a knife-blade edge engageable with said predetermined fuse clips.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
31 words
A multiple fuse adapter in accordance with claims 1 or 2 wherein: said plurality of fuse holders each being adapted to hold fuses of an ampere capacity less than 600 amperes.
Claim 8
Dependent Claim
19 words
A multiple fuse adapter in accordance with claims 1 or 2 wherein: said insulator plate comprises a plexiglass material.
Claim 9
Dependent Claim
39 words
A multiple fuse adapter in accordance with claims 1 or 2 further comprising: an insulator insert supported on said insulator plate such as to occupy the space between said opposing edge portions of said first and second metallic plates.
Claim 10
Dependent Claim
22 words
A multiple fuse adapter in accordance with claim 8 wherein: said insulator plate and said insulator insert each comprise a plexiglass material.
Claim 11
Dependent Claim
24 words
A multiple fuse adapter in accordance with claims 1 or 2 wherein: each of said first and second metallic plates comprises a copper material.
Claim 12
Independent Claim
194 words
A method of fabricating a multiple fuse adapter for use with first and second predetermined fuse clips spaced at a first predetermined distance from one another, the method comprising: providing first and second metallic plates and an insulator plate; mounting said metallic plates on said insulator plate such that the metallic plates lie in a plane, separated by a distance sufficient that one edge portion of each metallic plate is engageable with one of said predetermined fuse clips and that the metallic plates are electrically isolated from each other, with a further portion of the edge of one metallic plate facing a further portion of the edge of the other metallic plate, said further edge portions forming a pair of opposing edges; and affixing a plurality of fuse clip pairs to said metallic plates such that one clip of each fuse clip pair is affixed to one of said metallic plates and such that the clips of at least one of the fuse clip pairs are spaced apart at a distance greater than that separating the clips of another of the fuse clip pairs, said fuse clip pairs constituting a plurality of fuse holders.
Claim 13
Independent Claim
194 words
A method of fabricating a multiple fuse adapter for use with first and second predetermined fuse clips spaced at a first predetermined distance from one another, the method comprising: providing first and second metallic plates and an insulator plate; mounting said metallic plates on said insulator plate such that the metallic plates lie in a plane, separated by a distance sufficient that one edge portion of each metallic plate is engageable with one of said predetermined fuse clips and that the metallic plates are electrically isolated from each other, with a further portion of the edge of one metallic plate facing a further portion of the edge of the other metallic plate, said further edge portions forming a pair of opposing edges; and affixing a plurality of fuse clip pairs to said metallic plates such that one clip of each fuse clip pair is affixed to one of said metallic plates and such that the clips of at least one of the fuse clip pairs are spaced apart at a distance greater than that separating the clips of another of the fuse clip pairs, said fuse clip pairs constituting a plurality of fuse holders.
Claim 14
Dependent Claim
