Abstract
Abstract An electrical wiring distribution system including a metal raceway section having at least two parallel cells and an intermediate trough. Improved capping means is provided for enclosing the intermediate trough to provide an additional unobstructed electrical passageway. The present improvement increases the wire carrying capacity of the raceway section; utilizes a region of the metal raceway section which heretofore has been unavailable; provides separate raceways for power, telephone and signal conductors; and permits access to all three separate cells at each of plural locations in metal raceway section.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
110 words
In a metal raceway section adapted to be embedded in a concrete floor construction, said raceway section having at least a pair of spaced, generally parallel cells, said cells presenting spaced-apart crests and an intermediate valley and confronting sidewalls connecting the spaced crests to said valley, said confronting sidewalls and said valley defining a lengthwise trough, the improvement comprising: capping means enclosing said lengthwise trough to provide an unobstructed electrical passageway, said capping means comprising plural cover strips and at least one chamberdefining member interposed between a pair of said cover strips; said chamber-defining member extending above said spaced-apart crests, spanning across said lengthwise trough and overlying said spaced-apart crests.
Claim 2
Dependent Claim
110 words
In a metal raceway section adapted to be embedded in a concrete floor construction, said raceway section having at least a pair of spaced, generally parallel cells, said cells presenting spaced-apart crests and an intermediate valley and confronting sidewalls connecting the spaced crests to said valley, said confronting sidewalls and said valley defining a lengthwise trough, the improvement comprising: capping means enclosing said lengthwise trough to provide an unobstructed electrical passageway, said capping means comprising plural cover strips and at least one chamberdefining member interposed between a pair of said cover strips; said chamber-defining member extending above said spaced-apart crests, spanning across said lengthwise trough and overlying said spaced-apart crests.
Claim 3
Dependent Claim
19 words
The improvement of claim 1 wherein said confronting sidewalls diverge outwardly from said adjoining valley to said spaced-apart crests.
Claim 4
Dependent Claim
23 words
The improvement of claim 1 wherein each of said cover strips includes a central pan flush with the spaced-apart crests of said cells.
Claim 5
Dependent Claim
17 words
The improvement of claim 1 wherein the opposite ends of said cover strips extend beneath chamber-defining members.
Claim 6
Dependent Claim
32 words
The improvement of claim 1 wherein said cover strips include: a central pan and longitudinal side portions depending into said trough; and means connecting said cover strips to said metal raceway section.
Claim 7
Dependent Claim
32 words
The improvement of claim 5 wherein said connecting means includes: each of said confronting sidewalls having embossments extending into said trough; and said side portions having outwardly concave grooves engaging said embossments.
Claim 8
Dependent Claim
65 words
The improvement Of claim 1 wherein each of said chamber-defining members comprises: an enclosure having a bottom wall overlying said spaced-apart crests and provided with at least one opening which exposes said spaced-apart crests to the interior of said enclosure and provides communication between the interior of said trough and the interior of said enclosure; and means connecting said enclosure to said metal raceway section.
Claim 9
Dependent Claim
49 words
The improvement of claim 7 wherein said connecting means comprises: each of said confronting sidewalls having embossments extending into said trough; and opposed flanges depending from said enclosure into said trough, said opposed flanges being generally parallel with said confronting sidewalls and having outwardly concave grooves engaging said embossments.
Claim 10
Dependent Claim
13 words
The improvement of claim 8 wherein said opposed flanges adjoin said bottom wall.
Claim 11
Dependent Claim
48 words
The improvement of claim 8 including a vertically presented divider plate captively retained within said enclosure above one of said spaced-apart crests and extending parallel with said cells; one of said opposed flanges adjoining said divider plate, and the other of said opposed flanges adjoining said bottom wall.
Claim 12
Dependent Claim
49 words
The improvement of claim 7 wherein said connecting means comprises: a pair of oppositely extending, reverse turned flanges depending from said bottom wall and extending transversely across said trough, said reverse turned flanges cooperating with said bottom wall to define recesses captively retaining end portions of said cover strip.
Claim 13
Dependent Claim
21 words
The improvement of claim 11 wherein each of said reverse turned flanges is provided with tangs frictionally engaging said end portions.
