The preferred embodiment of this application N l-f. 3,45 fi ed fda h. 2.8, 1, 35, for Detention window ripening. into United tates Letters P tent No.2,13 7A37, datedNovember 2.2, 1938;,

The disclosure in Fig. 6 is the same as. Fig.13 as, originally filed in, my copending application Serial No.il. ,5,75 filed December 14, 19.36, for Detention, window and. method or glazing same, ripening into UnitedgStatesLetters Patent No. 2,161,792, datedJune 13, W39;

The present'invention relates to a unitary pivctal bar about which a closure swings outwardly on one side ofthe pivotal bar and inwardly on the other side of the pivotal bar, which bar has arcuate surfaces adapted for engagement with a screen frame or any other particular means overlying the portions vacated by the. closure when swung into open position. This has been accomplished by providing a barhaving vertical and/ or horizontal portions extending into ar-cuate por tions, which arc uate portions contact the screen frame. and may form a seat for the glazing.

In the drawings the reference character ill; indicates vertical muntin'bars, as may best be. seen by referring to Fig. 1. The vertical mun tin bars it are interconnected by horizontal mu ntin bars 2. The one bounding thetop of he ventilating area, may havefa downwardly projecting flange or piece Hi welded thereto, so as to provide an abutment and a watershed for. the upperportion of the closure it, as may bestbe seen by referring to Fig. 2. V p

The closure i3 is pivotally mounted to swing with a pivotal bar 22 including an L-shaped portion 2d merging into a stem 28 constituting the stern of a substantially T-shaped portion having flanges one extending upwardly and one extending downwardly along an arcuate path. One leg of the L cooperates with one of the flanges 39 to form a glazing channel 3 L Aglass window pane 2a is mounted in the glazing channel or seat 34. p

The other leg of the L-shaped portion 24 merges, into an arcuate portion 3%, the outer surface. of which has the same radius or different radius. Both arcuate outer surfaces bounding the flanges 30 are concentric. The arcuate surface of the flanges 3Q engages a screen frame 40 overlying'the outwardly swinging portionof the closure. The arcuate surface of the portion 36 contacts a screen frame 42 overlying the inwardly swinging portion of the closure. Thearcuate surfaces of portions 39 and 35 travel through a circular path and always remain in is disclosed in my copending application Serial contact with the screen. frames. In Fig. 3 the closure has been swung into open position without losing contact with the screen frames.

In order to reduce corrosion the material of the pivotal bar may consist of aluminum, brass, stainless steel or any other suitable non-corrosive material. This prevents streaking of the screens placed on the under side of the closure. Instead of using non-corrosive metal for the entire bar, the bar may be electroplated with a suitable non-corrosive plating, such as chromium plating.

In the modification disclosed in Fig. 4, the L- shaped portion 50, together with the arcuate portion 52 are preferably made from comparatively soft material and the T-shaped portion 54 from hard tool resisting material. The stem of the T-shaped portion 54 is welded to one leg of the L-shaped portion 50. In this modification both of the flanges of the T-bar cooperate with one leg of the L-bar to form a pair of glazing channels', one above the stem and one below, as shown in Fig. 4. This arrangement provides a more solid glazing seat for the upper edge of the glass. The tool-proof or tool resistant material used in the T-bar 54 deters severance of the pivotal bar, thereby increasing the value of the pivotal bar as a multi-functional bar, that is, muntin bar, pivotal bar, contact bar and detention bar.

In the modification disclosed in Fig. 5, the L- shaped bar has been eliminated and instead a diagonal portion 60 has been used. This diagonal portion 60 has one end merging into an arcuate portion 62 and the other end merging into the stem I54 of the T-shaped bar. In this structure the flanges 66 of the T-bar cooperate with the stem thereof to form glazing seats.

In the modification disclosed in Fig. 6 a composite bar arrangement has been utilized in a rail guard window assembly wherein the L-shaped portion 10 is provided with a downwardly projecting flange I2 along one edge. The horizontal leg portion of the bar 10 is provided with a plurality of holes receiving round or other suitably shaped detention bars I4, as more fully disclosed in my copending application Serial No. 115,752, filed December 14, 1936, for Detention window and method of glazing same. The rail bars or L-shaped bars I cooperate with the vertical detention bars 14 to form a detention guard suitable for use in penal institutions or other places where there may be no ingress and egress of human bodies through the windows.

The T-shaped bar I8, preferably having tool resistant material embedded therein, may also be much harder or different than the material used in the L-shaped bar 10. One leg of the L-shaped bar cooperates with the T-shaped bar to form glazing channels I6, receiving the window panes 80 overlying the detention guard. In the modification shown, the channel above the stem of the T-shaped member is shallower than the channel below the stem. This facilitates insertion of the window panes. This is similar to the difference in the depths of the channels shown in Fig. 9, which will be explained more fully later. The same arrangement may be utilized in connection with Fig. 4, where the upper channel may, for example, be much shallower than the lower, so as to accommodate the glazing. Thus, a duo-functional rail guard window assembly is produced. The stem of the T-bar I8 may be attached to the L-shaped bar in any suitable manner. The angle bar I0 may be provided with an aperture 82 that is aligned with the stem of the T-bar I8 and with the detention bar 14. This aperture 82 is used as a pocket for receiving the welding material 84, which welds bars 10, I8 and when desired I4, into a unitary structure.

Instead of using horizontal pivotal or composite bars, these may be vertical bars, or for that matter, diagonally disposed bars. In any event, the closure swings about the pivotal bar.

In the modification disclosed in Fig. 7 the pivotal bar includes a bridge portion I00 having a downwardly projecting flang I02 and an upwardly projecting flange I04, forming spacing members for two pairs of window panes I06. Each end of the bridging portion I00 merges into an arcuate flange I08. The radius of curvature of the outer surface of each of these flanges has a common center. The ends of the pivotal bar are pivotally mounted in the frame of the window. The pivotal bar may extend horizontally or vertically. The upper portions of the flanges I 08 cooperate with the flange I04 to form longitudinal putty receiving pockets, which pockets are used as seats for the glazing I06 and the putty surrounding the edges of the window pane.

As the upper portion of the disclosure shown in Fig. '7 swings in the one direction and the lower portion swings in the opposite direction, it is necessary to provide screens II2 for the oppositely swinging portion, one located on the inside of the outwardly swinging portion and the other located on the outside of the inwardly swinging portion. The frame II4 of each screen H2 i preferably made from angle iron. The flanges IIB extending parallel to the glazing I08 abut the frame of the fixed portion of the window. The other flange II8 projects into the ventilating area towards the swinging closure. The inwardly projecting flange adjacent the pivotal bar contacts the arcuate surface I08, so as to provide fiy-tightness whether the closure is in open or closed position. This screen arrangement provides a screen that is substantially flush with the outer surface of the fixed portion of the window, only the thickness of the flange H6 and the screen overlying the same, extending beyond the outer surface of the fixed portion of the window. This results in a compact structure, neat in appearance, efficient, that can be easily constructed at a low cost. The double glazing results in low heat losses. The arcuate pivotal bar having merely the bridging portion I00 extending from the inside to the outside also reduces heat losses.

The frame bar I09 bounding the upper portion of the closure may be provided with a downwardly projecting flange III which forms a partition and putty receiving seats. As the glazing below the pivotal bar may be inserted any suitable distance up into the cavity between the arcuate flanges I08 and the downwardly projecting flange I02, the bottom frame member II5 has been provided with three upwardly extending flanges III cooperating to form glazing channels or glazing seats receiving the glazing and rigidly supporting the glazing in position along the bottom.

In the modification disclosed in Fig. 8 the pivotal bar I20, substantially circular in contour, is provided with a longitudinal slot I22 and a channel I24 located over the bridging portion I26. The slot I22 and the channel I24 form glazing seats. These seats support the putty surrounding the adjacent edges of the window panes. Outwardly projecting flanges I28 form stops, limiting the swinging movement of the closure about its pivot. The main purpose is to permit the pivotal bar I20 to be small in relation to the pivotal bar I40 has been shown.

- the closure swings.

. accepts window thickness. The swinging movement of the closure is arrested by the stops I28 abutting or engaging the inwardly projecting edges IIB of the screen frame. Thus, it is seen that the inwardly projecting edges I I8 of the screen frame constitute duo-functional edges in that the edges contact the arcuate surfaces of the pivotal bar and form a stop for the swinging movement of the closure.

Referring to the modification disclosed in Fig. 9, a composite bar has been shown including a channel-shaped portion I30,which may be of cast material, or suitably extruded material, and. a sheet metal member I32 substantially 3- shaped when inverted. The sheet metal portion I32 includes a channel portion I34 merging into horizontal portions I36, as viewed in Fig. 9, terminating in arcuate flanges I38, The sheet metal portion I32 may be suitably attached to the channel portion I by welding or in any other suitable manner. In this modification the channel in member I32 is much shallower than the channel in member I30. This permits insertion of the glazing upwardly into the upper channel over the lower edge, where it may be slipped into the lower channel. By having the channels of unequal depth this facilitates the glazing operation.

A pair of tool resistant members I35 is nestled between the arcuate portions I38 and the medial glass supporting portion of the assembly. The tool resistant rods prevent the easy severance of the pivotal bar assembly in the event inmates should try to effect an escape through the ventilating area.

In the modification shown in Fig. 10 a rolled This bar includes a pair of diametrically disposed arcuate surfaces I42. The center of curvature of these arcuate surfaces coincides with the normal axis of rotation of the pivotal bar, about which axis The bar I40 also contains a pair of glass supporting flanges I44, oppositely disposed with respect to the center of rotation of the pivotal bar and oppositely disposed with respect to a common plane formed by corresponding sides of the flanges, this comm-on plane containing the axis of rotation.

The flange I44 positioned above the common plane, as viewed in Fig. 10, has two upwardly projecting flanges I46 and I48 cooperating to form supports for the putty I50 surrounding the lower edge of the glass pane I52.

The opposite flange I44 positioned below the common plane, as viewed in Fig. 10, has two downwardly projecting flanges I46 and I48 coopcrating to form supports for the putty I50 surrounding the upper edge of the glass pane I54.

The glass panes I52 and I54 are offset with respect to a vertical plane extending through the axis of rotation of the pivotal bar I45, as viewed in Fig. 10. This offset relation permits the use of a pair of screen frames IE0 and I62, positioned adjacent to, but on opposite sides of the vertical plane referred to above. The screen frames have been shown as L-shaped in cross sectional area. It is within the purview of this invention to utilize any other suitable type of screen frame. Likewise, the screen above the pivotal bar may be aligned with the screen below the pivotal bar if so desired. The offset relation of the glass panes permits of such a construction.

By shearing or cutting away the flanges I44 adjacent each end, the projecting cylindrical core portion may be used as journals mounted in suitable hearings or holes in the fixed frame portion bounding the sides of the ventilating area. The core portion and also the flanges may have embedded therein non-annealable material, resulting in a tool resistant bar adaptable for use in detention and security windows. The upwardly projecting channel may in some installations be made shallower than the downwardly projecting channel or vice versa, for the same purpose as set forth in connection-with Figs. 4 and 9, that is, to facilitate the glazing operation.

Although glass panes have been referred to throughout the specification, it is within the purview of this invention to use any other sheet material that is translucent and/or transparent.

Although the preferred modification of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts which generally stated consist in a device capable of carrying out the objects set forth, in the novel parts, combination of parts and mode of operation, as disclosed and defined in the appended claims.
