Y., as signor to The Gotham Pressed Steel Corpora tion, New York, N. Y., a corporation of New York Application August 11, '7 Claims. My invention relates to window ventilators and has particular reference to ventilating de?ectors or shields placed in the lower portions of win dow's. Window ventilators of this type usually have de?ectors made of glass plates held in place by end brackets fastened to window frames. When ?tting a ventilator to a window, the glass plate must be therefore cut to the exact width it) between the brackets, this width more or less varying for different windows. Such an opera tion is highly objectionable, however, rendering the installation di?‘icult and requiring services of an expert glass cutter. In order to avoid this 15 di?iculty, two glass plates are sometimes used, telescopically sliding side by side. This ar rangement is also objectionable, however, two panes of glass being more expensive and requir ing special adjustable braces or rods on top and 20 bottom of the plates, and being less satisfactory from the standpoint of appearance than a single covering the holders but also serving as clamps to hold the sides of the holders together, the holders being preferably made in the form of .p-shaped pieces of sheet metal. My invention is more fully described in the accompanying speci?cation and drawing in which—' Fig. 1 is. a perspective view of my ventilator attached to an ordinary window. Fig. 2 is a perspective View of an end bracket 10 with a glass plate holder in a detached position. Fig. 3 is a sectional detail view of the bracket with the glass plate and a spacing block inside. Fig. 4 is a view taken on the line 4-4 of Fig. 3. Figs. 5 and 6 are detail views of a modi?ed ar 15 rangement for retaining the ends of the glass plate. . Figs. 7 and 8 are similar detail views of an other modi?cation. ,Fig. 9 is a detail view of still another modi?ca I have found, however, that it is possible to make horizontally adjustable ventilators, using 25 glass plates of a standardized length and provid ing adjustment in the end brackets. Windows in ordinary houses vary in width, as a rule, by a few inches only, say between 36 and 40 inches. By making the glass plates 38 inches long, for 30 instance, and the end brackets 3 or 4 inches deep, I can provide a ventilator readily attach able to any ordinary window. An object of my invention is therefore to provide a ventilator of a standardized construction which can be at 35 tached to any ordinary window by merely screw ing or nailing the end brackets to the window frame. Another object of my invention is to provide end brackets with detachable holders for the By making the holders detachable not only their manufacturing is simpli?ed, but their handling for shipmentis facilitated, the knocked down parts occupying much less space than the assembled brackets. Another object of my invention is to provide means for retaining the glass plate in the end holders in a ?xed position after the brackets have been fastened to a window frame. For this pur pose I provide adjustable blocks in the holders resting against the ends of the glass plate, or adjustable screws or plugs ?tted in slots or holes in the holders. Still another object of my invention is to pro vide sliding caps for the upper portions of the 55 end glass holders, the caps not only attractively 20 tion for holding the ends of the glass plate in position. plate. glass plate. 1937, Serial No. 158,480 (CI. 98—99) ' ’ Figs. 10 and 11 are detail views of still another modi?cation. > My window ventilator consists of end brackets 25 shown in- detail in Fig. 2 which may be formed of two pieces i and 2 each pivoted together at 3 and telescopically adjustable to different angles of opening as described'in my Patent No.2,016,764. A lug 4 on one piece and a hook 5 on the other 30 prevent the pieces from becoming entirely sepa rated. The outer piece or sector 2 has a ?ange 6 with rectangular apertures ‘I, the inner piece l having holes 8 for attaching the brackets, which are right and left, to the inner sides of a window 35 frame 9 by screws H3. The apertures ‘l are en gaged by resilient hooks ll formed in U-shaped holders l2 for a glass plate l3. The holders are made of sheet metal and the hooks l l are stamped out to register with the apertures 1. Thus the 40 brackets and the holders can be easily assembled together or taken apart to be packed for ship ment. The sides of the holders are spaced apart so as to provide room for the ends of the plate [3, the width of the sides of the holders being 45 su?icient to allow for ordinary variations in the width of the windows. I have found that holders 3 or 4 inches wide can be used with a large num ber of windows, having usually from 36 to 40 inches in width, the glass plate being about 38 50 inches long. In order to prevent longitudinal shifting of the plate after its assembly, I provide spacing blocks M in the holders resting against the ends of the plate [3. These blocks are pref erably made of wood or similar material which 55 2 12X 2,130,114: can be easily trimmed by an ordinary penknife brackets, and spacing blocks in the holders abut or similar tool.
