Abstract

599,567. Multi-panel ventilators. MORRIS, A. (Cornish, H. E.). Sept. 18, 1945, No. 24127. [Class 137] A multi-panel louvre ventilator has a guardplate hinged on an axis at right angles to the pivotal axis of the ventilator panels on each side of the outside of the ventilator and a common operating lever effects the displacement of the guard - plate and the panels. As shown a number of channel sockets 2 for the panels are mounted on spindles which rotate in the side frame 6, and carry teethed pinions 7 which mesh with the teethed rack bar 8. Integral with or connected to this bar is cam plate 8 having a pin and slot connection 10, 11 with the lever 12 pivoted at 13 to the frame 6. The link 14 connects the lever 12 to the hinged guard-plate 17. The pivoted lever 19 is linked to the rack bar at 20 and when operated moves the bar and thus rotates the pinions 7, and moves the plate 9, causing the lever 12 to pivot, which through the link 14 moves the guard-plate to the closed position where it enshrouds the panel ends with its shaped edges. The panel may be locked in any position by the screw 23, 24 which causes the serrations 25, 26 to engage. The rack bar may be urged to contact the pinions 7 by means of leaf springs.
