SEALED LAY-IN WI~ÆWAY
The invention comprises a pivotally mounted bridging member on a pair of channel members located between their covers and carrying a mechanically connected sealing plate which is moved upwardly into sealing position so that its gaskets cooperate with the cover gaskets and with sealing flange gaskets to perfect an improved sealed lay-in wireway.
Brief Description of the Drawings A detailed description of one preferred embodiment of our invention is hereafter described with specific reference being made to the drawings, in which:
Fig. 1 is a perspective view of a portion of our sealed lay-in wireway; ~
Fig~ 2 is a perspective view of the same with one cover open and the other latched in closed position;
Fig. 3 is a fragmentary vertical sectional view, taken along line 3~3 of Fig~ li Fig. 4 is a fragmentary sectional view similar to Fig. 3 but showing the sealing plate shifted forwardly;
Fig. 5 is a fragmentary sectional view of the same with the sealing plate shifted rearwardly;

Fig. 8 is a fragmentary vertical sectional view taken along line 8-8 of Fig. 7; and Fig. 9 is a fragmentary sectional view taken along line 9-9 of Fig. 7O
Detailed Description of the Invention Our new sealed lay-in wireway comprises a plurality of U-shaped channel members 10 and 11 which have cover members 12 and 13. They have adjacent end portions 14 and 15 connected by bolts 16. Each has sealing flanges 17 and 18 separated by a gasket 19 of same shape and sizeO
Each channel member has an open side, one being defined by flanges 20 and the other by ~langes 21.
Cover 12 has a lip 22 which cooperates with latch members 23 ~or locking same. Cover 13 has a lip 24 which also cooperates with latch members 25.
Cover 12 has a continuous gasket 26 on its underside along its periphery which bears upon flanges 20 20. Cover 13 has a similar gasket 27 on its underside which bears upon flanges 21.
Pivotally mounted by bolt 28 is bridging member 29 which is rectangular except that it has a pivot ear 30, a notch 31 and notch 32 in opposite end portions.
25 These notches accommodate flanges 17 and 18, (Fig.2).
Plate 33 is mounted on member 29 and is ~lat except for depressed portions 34 and 36. Portion 34 carries a gasket 35 and opposite end portion 36 carries a similar gasket 37.
Mounting ear 38 extends through a member 29 and is received within cam 39 lever 40 and rounded corner 41 for camming. Pin 42 pivotally mounts cam 39 upon ear 38. Member 39 is unlocked in Figs. 3-5, locked in Figs. 6-9, inclusive. Sealing plate 33 when locked, is drawn tightly upwardly against member 2g, (Fig. 6).
In use, cover members 22 and 24, member 29, and plate 33 are swung to open position, (Fig. 1) so the ~ .
3~ ~
wiring can be easily and conveniently laid within members 10 and 11, (and others).
The member 29 is necessarily closed before members 12 and 13 are closed. To accomplish this, plate 33 is moved forwardly as shown in ~ig. 4, plate 33 clearing flange 20. When member 29 reaches the flanges 17, 18, plate 33 is shifted towards bolt 28, its outer end clearing flanges 20 and 21 at the opposite side, (Fig. 5). Member 29 swings closed, plate 33 is moved forwardly, and lever 40 is swung to the position shown in FigO 6, causing plate 33 to be cammed tightly against member 29. Gaskets 35 and 37 are compressed, (Fig. 6), and a seal is perfected between plate 33 and flanges 20 and 21, along depressed portions 34 and 36 of plate 33, and with flange gasket 19.
When members 12 and 13 are closed and latched 15 (Fig. 2), gaskets 35 and 37 are drawn by cam 39 against gaskets 26 and 27 to seal therewith. If members 12 and 13 are closed after cam 39 is locked the cover members will bring gaskets 26 and 27 into sealing relation with the ends of gaskets 35 and 37 and in~o sealing relation with the upper surface of the sealing plate 33, along each of its sides. Thus, a perfect seal will be effected at all of the joints between the sealing plate and the cover members, and the sealing plate and the channel members, as well as between the channel members, the cover members, the sealing plate, and the flange gasket.
It will be noted that we have eliminated any need for perfecting a seal around the end of a metal plate, which heretofor caused serious problems. There is continuous sealing contact around all openings when 30 seals 35 and 37 bridge the gap between seal 19 and sea].s 26 and 27. The sealing function provided by this wire-way is most satisfactory and effective in excluding lubricants, moisture and corrosive dust. Our wireway also provides a quick, simple and easy release, requires no tools, and cannot become lost.
In considering this invention, it should be r~lE~ered that the present disclosure is illustrative , .
only and the scope of the invention should be determined by the appended claims.
