Specification of Letters Patent.

rammed June so, rare.

Application filed December 20, 1912. Serial No. 737,799.

To all whom it may concern Be it known that I, FREDERio PARKER, of Bedford, in the county of Middlescx and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Window-Shields, of which the following is a specification.

My invention relates to means adapted to shield a window fro-1n the sounds arising from a noisy street. A shield adapted for this purpose has heretofore been constructed and successfully used.

My present form of shield while constructed on the same scientific principle, viz: that of reflecting sound without materially excluding light, is simple in construction, easy to adjust and keep clean and may be used also as fire shutters for the window to which it is applied.

My invention will be understood by reference to the drawings, in which Figure 1 is an elevation of a window to which my shield has been applied in its preferred form, the shield being out of use. Fig. 2 is a horizontal section taken near the top of the window showing the shield in use. Fig. 3 is a top view showing my invention used as fire shutters, and Fig. 4 is a vertical section through the middle of the window showing one of the shutters in elevation.

A. are the sashes of the window, A being the sill, A being the window ledge, and A the outer wall of the building. Themain part of the window shield comprises two members B and B in the nature of shutters each constructed in the form of my invention shown of a metal frame 6 having a suitable crossbar b dividing it into two parts, this frame holding two plates 6 and preferably made of wire glass or other similar transparent material of such character as not to be affected by ordinary fire exposure. Each one of these members is provided with hinges b 6 by which it may be hinged to the side of the window.

In the preferred form of my invention each member is wider than half the width of the window so that when bowed or so closed together as to bring their outer edges in contact with each other they will form an angular inclosure or ventilating passage B (see Fig. 2 whereeach member is shown at approximately an angle of forty-five degrees with the vertical plane of the wall of the building, the two outer edges of the members being in contact.) When the window is open they deflect waves of sound from entering the window so as to reduce materially the noise which would otherwise enter the room. In addition as shown each member carries an extension C, C preferably hinged to its lower edge and shaped to close in the bottom of the passage B so that the opening thereto is only at the top. These extensions C, C are preferably hinged each to its own member B, B in such a manner that when raised into vertical position as shown in Fig. 1 they will lie within the projection formed by the frame 6, b 22 In practice these members B, B may be thrown out of use in which case they may be looked back against the outer wall of the building A by any suitable fastener a, as shown in Fig. 1, or the members may be bowed as shown in Fig. 2 in which case the extensions C, C are dropped'into horizontal position, one extension carrying a hook c and the other an eye 0 so that they may be locked in place, these extensions in this case resting upon the window ledge A It will be noted in Figs. 1 and 3 that one member B has a hook b on its upper edge and the other an eye I). When these members are bowed as above described the hook b and eye 6 above referred to are caused to engage, thus holding the members themselves in place. In addition these members may be used as fire shutters, that is, they may be closed over the window at night as because of their relative width they will overlap. The hinges b for one member are mounted on an offset 6 of a thickness substantially equal to the thickness of the other member and when the two are shut together over a window (see Fig. 3) they may be held closed by means of a turn-button or in some other convenient way. The turnbutton which I prefer is shown in Fig. 3 and comprises a spindle (Z passing through one of the members and having on the inner end a handle al by which it may be turned and on the outer end a finger (Z which when turned into the position shown in Fig. 8 overlaps the overlapping member and holds the two members closed against the window frame.

In case of fire where it is necessary to enter the window, it is a simple matter to turn'the finger (Z to release the members B so that the shutters may be opened from the outside. Under ordinary conditions the members may be locked in this way at night and hence provide ample 'fire protection'to the building inside.

It will beclear to any one skilled in the art that my invention may be otherwise applied. In its preferred form it consists primarily in shutters or shield members each wider than half the window so that when the ends are brought together they Will abut, leaving a. passage such asB these members being constructed preferably of Wire glass whereby they will be transparent or at least translucent, thus reducing but little the amount of light which gets into the shown that a'large portion of the sound wavesrising from a street may be sufficiently deflected by such to enable a room to'be used comfortably for purposes of dictation, telephoning, conferences or other such purposes while the window is open even when the room is upon a very nolsy street.

I do not mean 'to limit myself to shutters proportioned exactly as shown or to a pair of shutters, each being made in one piece, nor to shutters which are transparent or translucent, my purpose being to provide a closure which shall be sufiiciently long or so shaped or jointed as to enable it to form with the window a chamber of suiiicient size to give plenty of fresh air to the room when the window is open and at the same time to present to the sound waves an obstruction which shall deflect them from their direct course into the room.

l/Vhat I claim as my invention is:-

In combination with a window frame, two members each wider than one half the width of the window frame, one hinged at each lateral. edge of said frame and each having a floor member hinged to it, means for looking the outer edges of said first-named members together in bowed relation, and means for supporting said floor members in horizontal position to close the passage between said first-named members and said window frame.
