Abstract

A sealed lay-in wireway comprised of channel members secured together in end-to-end relation with sealing flange gaskets thereinbetween and having longitudinally spaced covers having resilient gaskets extending continuously along their periphery and having a pivotally mounted bridging member extending along their open sides between the adjacent ends of their covers which shiftably mounts a sealing plate thereunder, the sealing plate having gasket material at each of its ends which bears against inwardly extending flanges of the channel members when drawn upwardly by a camming mechanism carried by the bridging member, the upper surface of the sealing plate at the same time bearing against gasket material carried by the ends of the covers to cooperatively perfect a seal at all of the joints.

Dependent claims

In a lay-in wireway:

(a) a pair of channel members connected end-to-end and having corresponding open sides through which wiring may be placed within said members;
(b) covers hingedly connected to said channel members and constructed and arranged to close the open sides of their respective channel members;
(c) a movably mounted sealing plate pivotally connected with at least one of said channel members and constructed and arranged to extend transversely across the open sides of said channel members at the connected ends thereof;
and
(d) means for sealing the joints between said channel members and said covers, the joints between said channel members and said sealing plate, and the joints between said sealing plate and said covers when the latter are closed;
(e) said means including said sealing plate and mechanism for moving said sealing plate upwardly into sealing position relative to the underside of said covers when the latter are closed;
(f) said covers and said sealing plate being constructed and arranged to be moved without dissembly to open position to permit unobstructed placement of wiring in said channel members.
