Abstract

660,456. Louvre ventilator; windows. JOHNSON BROS., Ltd., G., and JOHNSON. H. C. Aug. 17, 1949 [Aug. 17, 1948; Feb. 16, 1949]. Nos. 21694/48 and 4249/49. Classes 20(iii) and 137 A louvre venti- 1 a t o r comprises opaque or transparent slats 1 which are pivoted to vertical weather fillets 6 so that. when the knob 11 is rotated by hand, the slats 1 swing in unison to open or close the ventilator. The slats 1 are mounted in channelshaped holders 2, the channel walls being cut away at one side at the top, and at the other side at the bottom, to permit adjacent slats to make contact with one another when the ventilator is closed. The holders 2 are pivoted in the mounting member 3. The ends of the pivots. apart from that of the lowermost slat may carry enlarged heads tc prevent withdrawal from the mounting members. Flanges 15 of the holders 2, are pivotally connected at 7 to a flange of the corresponding weather fillet 6, the other flange of fillet 6 being ribbed to provide a weatherproof closure with the member 3. The lowermost slat is mounted on a trunnion 8, and is adjusted by rotation of the knob 11 and the screwed shaft 10 which extends into a box-like bracket 9. A nut 12 is moved along the shaft 10 and swings a slotted link 13, pivoted to the nut 12 about an axis parallel to the trunnion 8. A rib 14 formed on the trunnion adjacent the bottom of the bracket 9 mates with the slot in the link 13, so that the lowermost slat is swung with the link. According to the earlier Provisional Specification, the lowest slat is swung by a worm gearing.
