3 Claims.

This invention relates to windows and means for operating the same and it has for its object to provide an improved type of construction arranged to automatically open and close in acicordance with the strength and direction of the wind so that the maximum ot ventilation may be had within a building without undue draft.

Further objects and advantages of the invention will be set forth in the detailed description ;as follows:

In the accompanying drawing Figure 1 is a vertical sectional view of a window constructed in accordance with the invention, and

Fig. 2 is a front elevation thereof.

Like numerals designate corresponding parts in both the gures of the drawing.

Referring to the drawing, 5 designates a window frame set in the wall 6 of a building. The j composite window of the present invention comprises a plurality of hinged panels 7 consisting of the frames 8 and glass or other transparent panes 9. The upper corners of the frames 8 are hinged, at 10, to the undersides of parting strips l11 and the lower edges of the frames have a weather tight seating upon the upper edges of said parting strips when the window is in closed position, as indicated at 12.

vertically movable bars 13 are hung upon the links 14, the outer ends of the latter being pivoted, at 15, to the window frame. The bars 13 comprise the two outside portions 13a and 13b with an intermediate portion 13e that is cut out or rabbeted, as indicated at 13d for the reception of curved thrust links 15. The inner ends of these links are pivoted, at 16, to the composite bars 13 while their outer ends are pivoted, at 17, to the lower portions of the frames 8 of the respective panels or louvres. Springs 18 are con- Qlnected to the upper ends of the bars 13 and at their lower end are connected to the window frame.

The connection preferably includes some form of adjustment such as a turnbuckle 19 by which the tension of the springs may be adjusted. It

Awill of course be understood that the structure shown in Fig. 1 is duplicated at each side of the window.

In operation, the springs 18 pull downwardly upon the bars 13 and through the curved links 15' thrust the panels or louvres out to the dotted line position illustrated in Fig. 1, the bars being supported during this movement by the swinging links 14. The outward movement of the panels continues until the tension of the springs is just balanced by the weight of the panels. With only a light breeze blowing, the parts will maintain these positions, but if the wind increases in velocity its action upon the panels will be such as to tend to cause them 59. -IV to close. Thus, as the wind comes in gusts the window will automatically close and as the wind subsides the spring will act to restore the panels to open position.

Consequently, just the right amount of ventila- 6g. tion may be had at all times and the extent of the ventilation may be varied at will by adjustment of the tension of the springs under manipulation of the turnbuckle or other adjusting means. While I have indicated all of the curved arms as 79;. being of substantially the same length, it is to be understood that these may be varied if it be desired to make some of the panels larger than others or I may so adjust the pivotal connections as to cause some of the panels to open more than 755; others, i! desired.

One of the impor-tant advantages of the present arrangement is that if it is raining and the direction and strength of the wind is such as to tend to blow rain into the building, the windows will automatically close to prevent such action. I may, if desired, provide at each side of the Window a ratchet bar such as that indicated at 20 to be engaged by a pin 21 to hold the bars 13 against upward movement so that the panels will then be locked against closing movement under the iniiuence of the wind. I may also provide the bars with key controlled locks such as tha-t indicated at 22, the bolts of which, not shown, may be projected into a corresponding opening (not 99; shown) in the ratchet bar 20 to thereby positively lock the window in closed position under the influence of a key. The ratchet bar is pivoted at its upper end to the window frame and the pin 21 is carried by the bar 13. Since the bar 13 tends to 9 l rise against the action of the spring when the wind tends to close the panels 7, it follows that the engagement of the pin 21 with the teeth of the ratchet bar 20 will prevent such closing movement of the panels. Further, it will be seen that this locking will be rendered a positive one by the insertion of a key into the key hole of lock 22, said lock being carried by bar 13 and the shooting of the bolt of said lock endwise into engagement with ratchet bar 20 so that said ratchet bar cannot be moved upon its pivot to move out of its engagement with the pin 21.

It is to be understood that the invention is not limited to the precise arrangement herein shown and described, but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention, what I claim is: l. A structure of the character described comprising a plurality of horizontally disposed panels, panting strips to which said panels are hinged at their upper edges and upon which the lower edges of said panelsfhayea seating, a pair, of vertically movable bas'one at "each side" off the window, a pair of links connected to the lower portion of each panel at the opposite ends thereof the upper ends of said links being connected to said vertif cally movable bars, and tension springs tending to draw said bars downwardly." s

2. A structure of the character described comprising a plurality of horizontally disposed panels# gli parting strips to which said panels are hinged at their upper edges and upon which the lower edges of said panels have a seating, a pair of vertically movable bars one at each side of the window, a pair of links connected to the lower portion of each panel at the opposite ends thereof the upper ends of said links being connected to said Vertically" movable bars, tension springs tending to draw'said bars downwardly, and supporting links pvoted to the Window frame and to the said vertically movable bars, respectively.

' 3. A structure as recited in claim 1 in combination withlockingurneans for holding said bars against' vertical movement.
