` ,2 Claims.

Our invention relates to window construction for buildings of all kinds.

One of the principal objects of this invention is to provide a novelly constructed window for buildings, whereby the window opening may be substantially wholly uncovered or opened to provide maximum or full ventilation if desired, and a construction which at all times allows full light transmission, but which is constructed with only narrow openings to prevent ready egress or ingress of objects or persons.

Another important object of this invention is to provide a window of this class which is constructed of movable horizontal plates in the form of louvers but which allows maximum or full vision when the plates are shifted to closed positions.

An important object also is the provision of novel and simple means for rigidly supporting the ends of glass plates or panels whereby the edges only of the glass plates or panels are overlapped when the same are closed, and whereby the window plates or panels when closed may be located near the inner side of the window structure and the depth of the space for the window operating mechanism from the inner side of the window 4structure is reduced to a minimum.

Also an important object is the provision of a window construction of thisvclass in which no unsightly or undesirable springs or mechanism are visible from either side of the window.

A further important object of this invention is to provide a louver Window construction in which the separate plates or panels are pivoted at their opposite ends and in which each is shifted simultaneously atboth ends about'its pivoted axis to facilitate such shifting, and in which such shifting is initiated and eil'ected from unitary shifting means at one side of the window.

A still further object of this invention is--to provide novel and relatively simple hydraulic means for opening, closing, or adjustingwindows, and particularly for etfecting the foregoing window shifting operation.

I" An 4object also of this inventiony is to provide novel and simple hydraulic means for controlling or operating, by a single means, a battery of windows, and also a novel and simple hydraulic -means for remotely controlling or operating vwin- With thesev and other objects in view, as will appear hereinafter, we have devised a window construction for buildings having certain novel features of combination and arrangement of parts and portions, as will hereinafter be described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to thecharacters of reference thereon, which forms a part of this application, in

which:

Fig. 1 is a, fragmentary elevation from the inside of a window, embodying our invention in one form; I

Fig. 2 is a vertical section thereof taken through. 2-2 of Fig. 1, with-certain parts thereof broken away to facilitate the illustration;

Fig. 3 is a fragmentary sectional view in plan drawing, is housed in a window frame I, which is constructed similarly to other windows for buildings. Within the frame is a louver-iike con struction consistingof panels 2, which are preferably longV transparent platesy of glass supported at the ends by brackets 3, which are shown best yin Fig. 4.

of the panel or plate3. Atone, that is, at the i normally inner end, of the bracket is a bearing pin 3. the same being shown as extending at right angles backwardly from the bracket. The portion of the upper flange 3, nearest the bearing pin 3, is-cut away, as indicated by 3f. Likewise-the ex tended .end of the lower flange 3b is cut away, as

sockets positioned in the side of the window frame near the inner or room side thereof, and the plates are shiftable from substantially vertical depending positions outwardly therefrom.

If desired the bearing pivots of the plates may be any other suitable form of hinge.

The edges of the sides of the window casing Il of the frame I overlap the ends of the glass plates, as shown best in Fig. 2, forming ledges which are preferably lined with strips of rubber seal Il. These strips have oil-set surfaces or ledges at their outer sides which conform to and are adapted to be engaged by the end portions of the panels when the same are closed.

The supporting plate 3 of the bracket extends upwardly from the anges and is provided at its extended Iportion with a backwardly extending appearing pfn or trunnion 4 whereby the bracket may be shifted about the pivotal axis of the bearing pin 3.

At the opposite sides of the window frame are located operating members 5 which are shiftable vertically. These operating membersare preferably fiat strips and are positioned in conforming channels I in the side elements of the window frame. These strips are provided with substantially transverse slots 5a into which the trunnions 4 extend. Thus when the operating members 5 are raised or lowered, the trunnions 4 may move in the slots 5* for tilting the plates about the pivotal axes without causing the operating members 5 to move laterally.

If desired the slots 5* may he inclined outwardly and downwardly to facilitate the opening and closing of the plates.

The operating members are shown as slightly" recessed beyond the inner face of the side elements Id of the window frame. Over the lower ends of these operating members are plates 6 for guarding and guiding the lower ends.

The panels or plates of the window may be tilted outwardly about the pivots by a unitary slide Il which is shown as vertically shiftable on the inside of one of lthe side elements of the window frame. This slide has an inwardly extending lug II which is connected to the upper end of a plunger I2, which forms a part of and is reciprocally mounted in a master hydraulic cylinder I 3 rigidly mounted in the window frame. At each side of the window and on the inside of the side elements of the frame is an operating hydraulic cylinder I4, which is located in a recess at the lower end of the side element of the window frame and immediately behind the operating member 5. Each cylinder is provided with' a plunger I5 which is shown as directly connected to the inner side.

of the corresponding Voperating member 5. The lower end of the master hydraulic cylinder .is connected, by conduits I6 and I'I, to the operating hydraulic cylinders `I4 at the oppositev sides of the window frame. Thus when the slide II is shifted downwardly, fluid is forced into the cylinder I4, raising the operating members 5 and opening the window plates. If desired, a 'suitable lock (not shown) may beprovlded on the slide II, or connected elements, to prevent the window plates from being opened.

In the modification shown lin Fig. 5, the operating members 5 mayv be directly pivotally connected to the brackets 3. When so connected, the operating members move laterally. They are then connected to the plungers I5, of the operating hydraulic cylinder, by links 2 I.

The operating members 5 are raised by fluid pressure of the hydraulic cylinders. To aid the downward shifting of these members, we have provided tension springs I to urge the members 5 downwardly when the pressure in the cylinders is released. In order to hold the slide in a certain position, after having been shifted, we have provided transversely serrated engaging or other friction surfaces I and IIb between the slide II and the portion of the frame I engaged by the slide.

Our operating means for simultaneously operating the panels or windows from both sides or edges is applicable for operating windows other than the type shown. Such operating means, as disclosed, is applicable also, as shown in Fig. 6, for operating simultaneously all the windows of a battery by a unitary means or by a master hydraulic cylinder, and also for operating the window or windows from remote positions.

'I'hough we have shown and described a particular construction, combination, and arrangement of parts and portions, and certain modifications thereof, we do not wish to be limited to the same, but desire to include in the scope of our invention the construction, combination, and arrangement substantially as set forth in the appended claims.

We claim: I

1. In a window cons'tructi n, a window frame, a plurality of window panels, each pivoted at its opposite ends on the opposite sides of the frame, so as to permit the panels to be shifted about their pivotal axes outwardly from substantially Vertical, slightly overlapped positions, and an operating member iltted to slide vertically in a conforming channel in the outside of the frame laterally outwardly from the pivotal axes of the panels, the panels having pivot pins extending beyond the ends of the panels and spaced laterally outwardly from the pivotal axes thereof, said operating member having substantially transverse slots through which the pivot pins extend, said operating member being so constructed and connected to the panels that the latter are swung upwardly at their free outer portions as the operating members are raised.

2. In a window construction, a window frame,

Y a panel pivotally mounted at one end of the end edges on the opposite members of the frame, said panel having a right angle flange at one end, and having a pivot pin extending backwardly from said flange, and a long operating member longitudinally slidable at the outside of the window frame and spaced laterally from the pivotal axes
