11 Claims.

Our invention relates to window sashes and more particularly to metallic window sashes especially adapted for jail and reformatory use, but also applicable to other installation wherein it is l desirable to provide ventilating openings protected against entrance or escape.

In the present invention there is contemplated a structural steel window sash of large proportions such as are commonly employed in factory and warehouse construction, the transversely disposed mullion bars of which are comparatively closely spaced to afford a grating or grille having numerous small spaces, certain of which are closed by window panes leaving a group of such spaces to l5 afford a ventilating opening across which the sash mullions extend. This affords within the window sash structure a barred opening. Mounted at the interior side of such barred ventilating opening is an auxiliary sash adjustable relative to the main sash and nomrally closing said opening. Actuator means for the closure sash are mounted exteriorly of the main sash and operatively connected with such closure sash through restricted openings in the fixed portion of the structure. The-barred ventilating opening is further provided with a screen upon its exterior side or that side opposite the closure.

The object of the invention is to simplify the structure as well as the means and mode of operation of ventilated windows for jails, reformatories, and the like, whereby they will not only be cheapened in construction, but will be more efficient in use, of increased durability and strength, and unlikely to get out of order.

A further object of the invention is to incor porate in a single structure the window guard or jail bars and the window sash structure whereby the sash mullions become duofunctional.

A further object of the invention is to provide a compact structure of duofunctional character having a guarded or barred ventilating opening and to provide an adjustable closure for such opening- A further object of the invention is to provide a combination window sash and window guard or jail bar structure having a screened ventilating opening.

A further object of the invention isto provide in such a structure improved means for adjusting the closure of the ventilating opening from the outside of the sash structure.

A further object of the invention. is to provide a window sash having glass openings too small for the passage of a man, and having therein a ventilating opening including the area of a number of such glass openings formed by the intersection of transverse mullion bars extending across such ventilating opening.

With the above primary and other incidental objects in view, as will more fully appear in the 1930. Serial No. 431,117

specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation or their equivalents as hereinafter described and set forth in the claims.

Referring to the accompanying drawings wherein is shown the preferred, but obviously not necessarily .the only, form of embodiment of the invention, Fig. 1 is a front elevation of a window sash embodying the present invention.

Fig.- 2 is a vertical sectional view of the window sash structure taken through the ventilating opening.

Fig. 3 is a transverse sectional plan view thereof also taken through the ventilating opening. Like parts are indicated by similar characters of reference throughout the several views.

Referring to the accompanying drawings; 1 indicates a portion of the building wall in which is incorporated the structural steel sash 2. This sash comprises a frame 3 divided by transverse interlocking mullions 4 into a plurality of comparatively small spaces 5. The mullions 4 are comparatively closely spaced, whereby the spaces 5 are entirely too small for a person to pass through;. Most of these spaces 5 are closed by panes of glass leaving a group of spaces 5' vacant to form a ventilating opening as shown at 6. The mullions 4, however, continue transversely both vertically and horizontally across this ventilating space 6. The frame 3 and mullions 4 are formed of such' material and so interlocked as to constitute jail bars or a grille which may not be easily broken. Thus the sash mullions 4 are duofunctional. These mullion bars 4 not only serve their ordinary and usual purpose as parts of a window sash, but they also additionally function as jail bars.

Adjustably mounted interiorly of the main sash 2 and normally in registry with the barred ventilating opening 6, is an auxiliary closure sash '7. This closure sash may be of any suitable construction. It may be formed, as is the main sash, with, transverse mullion bars or, as shown in the drawings, may consist of a sash frame 7 containing a single continuous glass window pane 8. The closure sash '7 is hinged at 9 to the interior of the main sash 2. This hinge joint is preferably, though not necessarily, located at the bottom of the sash, whereby such closure sash may be tilted inwardly and downwardly to open the barred ventilating opening 6. Surrounding the ventilating opening and welded to the mullion bars of the main sash is an angle frame 10 upon which the flanged frame 7 of the closure sash abuts to form a tight joint. Located exteriorly of the main sash 2 is an operator shaft 12 extending transversely across the window opening and pref erably, though not necessarily, continuing through the masonry pilasters l of the building structure in which are embedded tubular sleeves or pipes 13 to receive such operator shaft. Adjacent to the barred ventilating opening 6 of the window sash the operator shaft 12 carries gear pinions 14 which mesh with arcuate rack bars 15 projecting through the main sash 2 and engaged with the adjustable closure sash 7. The sides of the sash frame 7 of such closure sash are preferably provided with arched ears or keepers 16 within which the ends of the rack bars 15 are pivoted. The glass panes in the spaces of the sash adjacent to the ventilating opening are notched at their corners to permit the passage of the rack bars 15. A cover plate or housing 17 is welded to the sash structure coincident with such notched window glass providing a keeper and enclosure for the rack bars. By thus positioning the operator shaft outside the sash structure, there are no projections nor apparatus within the building upon which the inmates may climb.' It is quite impossible for anyone confined within the building to interfere with the operation of the window sash closure 7. The operator shaft 12 may be rotated by any suitable means as such rotation will effect a relative adjustment of the closure 7 at the opposite side of the main sash 2 Disposed exteriorly over the ventilating opening 6 of the sash is a screen 18. This screen is mounted upon a suitable frame 19 enclosed within angle bars 20 welded to the mullions '3 about the ventilating openings. The screen being confined to the area of the ventilating opening, while the rack bars 15 pass through the window sash slightly beyond such opening, the sash operating mechanism does not interfere in any way with the screen.

While the ventilator closure has been shown on the inner side of the sash structure, it is obvious that if so desired it may be located upon the outer side of such sash and upon the same side with the operator mechanism. This would interpose the jail bar grille formed by the mullion bars intersecting the ventilating opening between the persons confined within the building and the closure sash 7. Thus interference with the operation of the closure would be further prevented.

The mullion bars and other members of the sash frame are of substantially conventional shape but are of somewhat increased dimensions in cross sectional area to agree with standard requirements for jail construction. The frame 8 of the closure sash is formed from standard sash bar section.

The sash 2 may be installed in the masonry in any suitablemanner. The flanged margin of the sash frame may be projected into a suitable recess provided in the masonry wall as shown at the top of the window sash, which recess is subsequently filled with concrete or other plastic sealing material. Otherwise, the flanged margin of the sash frame may be bolted or riveted to anchor members embedded in the masonry structure as shown at the bottom in Fig. 2 or as shown in the detail view Fig. 3 wherein such margins are shown riveted to anchor members 21 embedded in the masonry'wall.

As before mentioned the closure frame 7 preferably though not necessarily carries but a single pane of glass 8', whichis substantially coextensive with the ventilating area of the main sash and is therefore common to and overlies a plurality of the spaces formed within the ventilating area by the intersection therein of the transversely arranged mullion bars. By making the glass 8 of the closure of comparatively large size,

tially in the plane of the closure while the other set of flanges 7b are laterally disposed in the direction of the main sash .structure. The outwardly projecting flanges/ 7a abut upon the inner flange margin of the aflixed frame 10 while the laterally extending flanges 7b abut directly upon the mullion bars 4 of the main sash structure. This is true at both the top and the sides of the closure. However at the bottom of the closure a somewhat different construction prevails wherein the inwardly projecting flange 7b of the closure frame '7 is provided with a downwardly extending flange 24 which, in the present instance, is shown as an angle bar welded to the frame 7. This dependent flange 24 abuts in perpendicular relation upon the bottom frame member of the afiixed frame 10 when the closure is in closed relation as shown in Fig. 2 of the drawings. It will'be noted that at the bottom of the closure the frame 7 abuts upon the upturned flange 25 of the frame 10 in a lateral direction, while the dependent flange 24 of the'frame 7 abuts vertically upon the frame 10. The upturned inner flange 25 of the frame 10 forms an arresting dam for water or seepage and prevents moisture from seeping through the closure joint. The flange 10 overhanging the mullion bar at the bottom of the ventilating area, as shown in Fig. 2, forms a wa-' ter shed. The closure member making double contact upon spaced contact lines is quite effective in excluding moisture and air when the ventilator is closed. 1

While the ventilating opening may, if desired, be located marginally relative to the main sash, it is preferably located in a central or medial position, and is entirely surrounded by closed spaces. This is clearly apparent in Fig. 1, wherein the ventilating area is also illustrated as including mul,

tiple spaces both vertically and horizontally formed by the intersection of the mullion bars 4 within such area. Cross reference is made to copending application Serial No. 496,709 filed November 19th, 1930 wherein is shown a somewhat different species of the present invention but involving common subject matter.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
