Abstract
Abstract A supply rail for use in electrical distribution systems having a pair of hollow compartments separated by a center bar. Each compartment is provided with a slit opening for receiving a contact device. Each compartment is provided with a current bar carried on an insulated carrier body which is located on a sidewall of each hollow compartment. The carrier body abuts against abutments on said sidewall to produce an airgap between the carrier body and the sidewall in each compartment. The airgap is available to receive at the ends of the supply rail projections of insulating material to provide a connection means between sections of a supply rail or an end cap.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A supply rail for use in electric current distribution systems adapted for cooperation with a contact device having contact means, said supply rail comprising a hollow metal profile, a center bar extending the length of said profile dividing said profile into two adjacent hollow compartments, a slit-shaped opening in a front wall of each of said compartments for receiving said contact device, an insulating carrier body mounted within each of said hollow compartments and extending along a sidewall of said profile, abutment means located on each of said sidewalls so that said carrier body engages said abutment means spacing said carrier body from each of said sidewalls of an airgap thereby being established between said carrier body and the sidewall along which said carrier body is located, said gap extending the full length of each of said sidewalls and intended to receive insulating bodies at the end of the supply rail and an additional current bar for connection to ground mounted on said center bar,
Claim 2
Dependent Claim
165 words
A supply rail for use in electric current distribution systems adapted for cooperation with a contact device having contact means, said supply rail comprising a hollow metal profile, a center bar extending the length of said profile dividing said profile into two adjacent hollow compartments, a slit-shaped opening in a front wall of each of said compartments for receiving said contact device, an insulating carrier body mounted within each of said hollow compartments and extending along a sidewall of said profile, abutment means located on each of said sidewalls so that said carrier body engages said abutment means spacing said carrier body from each of said sidewalls of an airgap thereby being established between said carrier body and the sidewall along which said carrier body is located, said gap extending the full length of each of said sidewalls and intended to receive insulating bodies at the end of the supply rail and an additional current bar for connection to ground mounted on said center bar,
Claim 3
Dependent Claim
39 words
A supply rail for use in electric current distribution systems according to claim 1 wherein a cover lid is mounted on one of the ends of said supply rail, said lid having projecting insulating bodies located within said airgaps.
Claim 4
Dependent Claim
63 words
A supply rail for use in electric current distribution systems according to claim 2 wherein another supply rail having projecting insulating bodies is connected with the other end of said supply rail, said projecting insulating bodies of said other supply rail cooperating with the said airgaps of the said supply rail, said projecting insulating bodies overlapping the connection point beTween said supply rails.
Claim 5
Dependent Claim
26 words
A supply rail for use in electric current distribution systems according to claim 1 further comprising a current bar carried by each of said carrier bodies.
