SHEET-METAL VENTILATION-WINDOW.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed. August 11, 1916. Serial No. 114,402.

To all whom it may concern:

Be it known that I, DARIUS E. SHRAUGER, a citizen of the United States of America, residing at Atlantic, in the county of Cass and State of Iowa, have invented certain new and useful Improvements in Sheet- Metal Ventilation-Windows, of which the following is a specification.

My invention relates to windows in which the frames, adapted to be set permanently in the walls of buildings, and the openable and detached sash closures therefor are both made of sheet-metal; and the objects of my improvement are, first, to provide means for setting the sash partially opened for ventilation, and still preserve the storm-proof features of the closed windows; second, to afford facilities for opening the window at both top and bottom simultaneously and retaining it thus opened; third, to facilitate the adjustment of size of such partial openings; and fourth, to safely and. conveniently dispose of detached glazed sash during a period of fully opened window. The above mentioned objects with others hereinafter more fully disclosed are attained by the structure and mechanism illustrated in the accompanying drawing, in which- Figure 1 is an outside elevation showing the glazed sash closed; Fig. 2, an inside elevation with the parts in the same position as in Fig. 1; Fig. 3, a vertical section through the closed window and portions of the wall above and below showing in broken lines the disposition of the glazed sash when the window is fully opened; Fig. 4, a plan or horizontal section of the closed window and adjacent wall at each side in which the frame is set, taken on the broken line of Fig. 3; and Fig. 5, is a fragmenta'l vertlcal section showing the disposition of the glazed sash when the window is partly opened both top and bottom, in all of which views the same reference numerals refer to the same parts of the mechanism or structure.

The soffit or. head -7, is composed of a single strip of sheet-metal and has an intermediate longitudinal portion bent downwardly upon itself to form the head stop 6. An outer edge portion is bentto stand upwardly and serve as the head casing 8.

The jambs 4 have each an intermediate vertical portion bent inwardly upon itself to form the stops 5 and 5 coinciding with and mitered at their top ends with the ends of the head stop 6. These stops are not continued to the foot of the jambs; the jambsheets below being split and lapped to take up the excess of width below the lower end of the stop; the space below the lower ends of the stops accommodate the ends of the outwardly-inclined lip 12 of the bottom rail of the sash, as shown in Figs. 1 and 3. Outer edge portions are bent outwardly, into a plane agreeing with the outside face of the wall, to form the side casings 8 and 8 having their top ends disposed back of the ends of the head casing, as indicated by dotted lines in Fig. 1, and shown in Fig. 2.

Integral triangular extensions of the inner edges of the j ambs form the cheeks 18, standinginwardly from'the inner face of the wall, as shown in Figs. 8 andt. The lower longer edges of these extensions are bent to form the stiffening flanges 19 and 19, having their inner projecting portions doubled upon themselves for greater strength and smoothness. A cross-bar 20, of sheet-metal doubled upon itself in cross-section, has its opposite ends fastened to the top ends of the flange. The triangular extensions and crossbar form a rack or holder for the opened sash, as will be hereinafter further described.

The sill of the frame is made of an integral strip of sheet-metal having an intermediate portion adjacent to its inner edge bent upwardly to form the longitudinal upstanding angular ridge 9, to properly weather the sill. A front edge portion is bent downwardly to a coincident plane with the side casings, to which its ends are fastened, as are the other portions of the sillends also fastened to the jambs, in the usual manner.

The bottom rail of the sash, composed of a single strip of sheet-metal, has an intermediate portion bent upon itself to form the longitudinal upstanding flange 10, of double thickness, to back the bottom ends of the panes of glass. An adjacent parallel portion is bent upon itself to form the inwardly and downwardly inclined lip 11. The adj acent opposite edge portions of the strip are bent to close flatly against each other, in an outwardly-standing base 29 beneath the lower edges of the panes-which stand thereon,and are then bent to terminate in the double lip 12 inclined outwardly and downwardly, to'closelonto the frame sill in front of the weather-angle 9, as shown in Fig. '3. V V v The stiles and munnion are substantially alike instructure; each is composed of a singlestrip of sheet-metal. A central longitudinal portion of the strip is bent equally upon itself from both edges, to form the 3 inner double flanges 13 of double thickness.

Adjacent opposite side portions are bent to stand outwardly at right angles to and centrally of the inner flanges and closed flatly against each other to form a connecting web 30. And the remaining edge portions of the strip are bent apart to form the outer flanges '14, standing oppositely inthc same plane;

they are thus spaced away from the inner flanges, by the web portion, to form at both sides, of munnion or stile, grooves to receive the edges of thepanes of glass. In the stiles the outer grooves could receive the springs, chains or cords for connecting weights or sash balances of sliding windows. The inner 'top ends of the'stiles and munnion. This completes the sash members, leaving the grooves open at the top ends for the insertion of the glass panes. A corner 15 of the top end of the single flange, is bent in above the glass to retain it in the sash. The sash members, like those of the frame, are joined by mitering, interlapping, riveting 7 and soldering in the usual manner.

The inclined lips of the sash bottom-rail I form an angular groove adapted to straddle the weather-angle 9, of the sill, thereby pivoting the sash at the bottom, to allow the top to swing inwardly against the flanges 19 of the cheeks, or toclose outwardly against the stops 5 and 6. Latch-buttons,

each'consisting ofa latch end 22 and an in- .wardly inclined thumb flange 23, are pive 'oted. intermediately near the top and on the v V backs of the stiles. Radial'slots' 21 through the cheeks receive the outwardly swung I latch ends to set the inwardly swung top ofthe sash at a desired position for top ventilation. When these buttons are turned "vertically, as indicated by the dotted lines 24 in Fig. 2, the inclined thumb flanges 23 are adapted to hook over the cross-bar 20,

to support the inwardly swung and upwardly slid sash for both top and bottom ventilation, as shown in Fig. 5. For smaller 7, op nspaces, both top and b t 'the'head edpins 26 are set in selected perforations 25 in the lower'ends of the flanges 19 of the cheeks and the latch-ends of the buttons reversed or swung downwardly and outwardly will engage any desired slot to adjust the top opening. For full opening, the sash is drawn upwardly entirely out of the frame, the groove of the bottom rail is seated on the cross-bar 20, and the top of the sash, inclined against the wall above the frame, is secured by the bent button 28, as shown and indicated by dotted lines in Fig, 3.

I claim:

1. In a sheet-metal ventilation window, a sill composed of a single strip having a portion bent to form an upstanding weathering'ridge, and jambs each made of a strip having an intermediate longitudinal portion bent upon itself to form a sash-stop the lower end of which is spaced upwardly from the weathering ridge of said sill, in combination with a detached rocking sash, and a sash bottom rail composed of a strip bent upon itself in cross-section to form an inwardly and downwardly inclined longitudinal lip and an outwardly and downwardly inclined lip spaced therefrom to form a longitudinal groove adapted to straddle the weathering ridge of the sill in the spaces below the lower ends of said stops.
