COLDJIR FACE.
Application le June 16, 1922.
il oi" llflinnesota, have invented certain new and useiful linprovenients in specifica- Faees. of which the following is a tion.
rllhis invention is partieularl)v useful in connection with heating' plants oit the hot air type. Formerly. the air supplied to such a plant was drawn from outside the huildiniff to he. heated, thereafter passed thru .the heater and then distrilnited to the building lilore recentlyv it has been the `better practice to draw the cold air iiiron'i the lniilding' interior by nieans ot conduits, pipes or chutes' leading' iroin one or two points in the building; to the heating plant. rlhese cold air conduits usually terminate in horizontal openings provided in the floor or in vertical openings in the mop-hoard or hase-hoard. so that the relativelv cold, and therefore heavier.y air Will readilv descend to the heater. Circulation ot air] is thus provided. These vertical .or horizontal pipe openings are customarily7 provided with what are known in. the trade as cold air faces. A function of the face is ii" to permit air passage but to prevent passage t anziani-e into the nine. A disadvantage or Serial No. 568,772.
be understood that the invention is not confined to the exact features shown as varieiis changes may be inade within the scope of the claims which follow.
ln the drawings:
Figure 'l is a view in plan oi :i cold air face with its seat shown in operative position in a lioor;
Figure 2 is a vertical sectional view on the line 2 2 of Figure l and showing` the tace closure in norinal open position; n
Figure 3 is a fragment-ary vie`\v similar to that oit Figure 2 but showing the 'face traine in a position reversed with relation to that oil Figures l. and 2, and with the closure or cover in closed position;
Figure 4L is a Yfrag-mentar)i view in perspective of the elements forming the reticulated portion oit the tace; and
Figure 5 is a detail vie-W showing` the preferred method of interlockingv the intersecting` elements.
AIn the selected embodiment ot the in vention the face is forme-d with a frame having` sides 6 and ends 7. This traine is preferably orined of a single piece ot narrow sheet metal shaped into a rectangular 'forni and having its abutting ends Welded to gether. This open frame is provided with a retieulated portion completely covering the area comprehended by the traine. The
