Claim 1
Independent Claim
300 words
An article of manufacture comprising a cover for a telephone terminal block having a base plate, and a normally upright terminal-mounting plate supporting terminals extending laterally from the opposed sides of said mounting plate, said mounting plate having oppositely disposed top and bottom ends and a free edge extending therebetween, said cover being made of electrical insulating material and being slidably mounted on said terminalmounting plate in a first operative position and being removable therefrom to a second inoperative position, said cover comprising: a normally upright sidewall; a top wall fixedly connected to and projecting laterally from one end of said sidewall, and a bottom wall fixedly connected to and projecting laterally from an opposed end of said sidewall and in confronting, spaced relationship relative to said top wall; a first pair of arms depending from said top wall in laterally spaced and parallel relationship to one another; a second pair of arms projecting upwardly from said bottom wall in laterally spaced and parallel relationship; said first and second pairs of arms being in spaced parallel and confronting relationship and being adapted to slidably receive marginal portions of said top and bottom ends, respectively, of said terminal-mounting plate between each one of said pairs of arms; and an end wall extending between and fixedly secured to said top and bottom walls and fixedly secured to the adjacent marginal edge of said sidewall to project laterally therefrom in the same direction as said top and bottom walls, and laterally spaced and substantially parallel means on said end wall slidably receiving said free edge of said terminal-mounting plate therebetween; said sidewall being supported in spaced relation relative to said terminals at one side of said mounting plate when said mounting plate is in position between said first and second pairs of arms.

An article of manufacture comprising a cover for a telephone terminal block having a base plate, and a normally upright terminal-mounting plate supporting terminals extending laterally from the opposed sides of said mounting plate, said mounting plate having oppositely disposed top and bottom ends and a free edge extending therebetween, said cover being made of electrical insulating material and being slidably mounted on said terminalmounting plate in a first operative position and being removable therefrom to a second inoperative position, said cover comprising: a normally upright sidewall; a top wall fixedly connected to and projecting laterally from one end of said sidewall, and a bottom wall fixedly connected to and projecting laterally from an opposed end of said sidewall and in confronting, spaced relationship relative to said top wall; a first pair of arms depending from said top wall in laterally spaced and parallel relationship to one another; a second pair of arms projecting upwardly from said bottom wall in laterally spaced and parallel relationship; said first and second pairs of arms being in spaced parallel and confronting relationship and being adapted to slidably receive marginal portions of said top and bottom ends, respectively, of said terminal-mounting plate between each one of said pairs of arms; and an end wall extending between and fixedly secured to said top and bottom walls and fixedly secured to the adjacent marginal edge of said sidewall to project laterally therefrom in the same direction as said top and bottom walls, and laterally spaced and substantially parallel means on said end wall slidably receiving said free edge of said terminal-mounting plate therebetween; said sidewall being supported in spaced relation relative to said terminals at one side of said mounting plate when said mounting plate is in position between said first and second pairs of arms.
Claim 3
Dependent Claim
42 words
An article of manufacture as defined in claim 1 wherein: said first and second pairs of arms and said receiving means on said end wall cooperate to form C-shaped guide rails and stabilizing means with said receiving means forming the bights thereof.
Claim 4
Dependent Claim
19 words
An article of manufacture as defined in claim 2 wherein: said cover is formed of a flexible resilient material.
Claim 5
Dependent Claim
59 words
An article of manufacture as defined in claim 3 wherein: said top and bottom walls between their respective pair of said arms are formed with transversely extending slots therebetween to form a tongue having a free end; and a friction tab on each of said tongues for engaging, respectively, the adjacent upper and lower ends of said terminal-mounting plate.
Claim 6
Dependent Claim
62 words
An article of manufacture as defined in claim 4 wherein each of said tabs is frusto-pyramidal in configuration providing an inclined sidewall adjacent the free end of its associated tongue to facilitate the mounting of said cover on said terminal-mounting plate and to provide a friction edge acting as a drag on the immediately adjacent one of said top and bottom ends.
Claim 7
Dependent Claim
18 words
An article of manufacture as defined in claim 5 wherein: said cover is formed of a transparent material.
Claim 8
Dependent Claim
121 words
An article of manufacture as defined in claim 2 wherein: said cover including said rails is formed of a resilient flexible material and wherein said C-shaped rails in the operative position of said cover converge towards one another with the components of each of said rails forming an acute angle with the wall on which each is connected; one of said C-shapEd rails flexing, when said cover is slidably mounted on said terminal-mounting plate in its operative position, to extend flush against adjacent portions of one side of said terminal-mounting plate, and the other of said C-shaped rails flexing into engagement with adjacent portions of said terminal-mounting plate on its other side to releasably clamp said terminal-mounting plate between said rails.
Claim 9
Dependent Claim
18 words
An article of manufacture as defined in claim 7 wherein: said cover is formed of a transparent material.
