Claim.

This invention relates to protecting means for use in connection with windows, the primary object of the invention being to provide a storm pane which may be readily and easily installed on window frames to protect the windows against pressure directed thereto, incident to the exploding of an atomic bomb, rockets, guided missies, and other defense apparatus.

An important object of the invention is to provide a protecting window which will direct uniform pressure against the window pane with which the device is used, thereby reducing window vibrations and window breakage to a minimum.

Another object of the invention is to provide means for bracing the protecting window at various points over the surface thereof, securely holding the protecting pane in position.

A still further object of the invention is to cushion the movements of the outer storm or protecting pane with respect to the window pane to further reduce window pane vibrations and consequently reduce window pane breakage.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a vertical sectional view through a window equipped with a protecting pane, constructed in accordance with the invention.

Fig. 2 is a fragmental front elevational view thereof.

Fig. 3 is a vertical sectional view through a modified form of the invention.

Fig. 4 is a vertical sectional view through a further modified form of the invention.

Fig. 5 is a horizontal sectional view of a still further form of the invention.

Referring to the drawing in detail, the reference character 5 indicates a window frame which is of a conventional structure and includes the window pane 6 held within the window frame 5 by the putty indicated at 7.

The protecting pane forming the subject matter of the present invention is indicated by the reference character 8 and is constructed of any desirable transparent plastic material, shockproof and fire-proof glass or the like, the inner) surface of the protecting pane being supplied (CI. 20—40) with strips ;o.f sponge rubber 9 that extend transversely across the protecting pane adjacent to the upper and lower edges thereof, as well as at a point intermediate the ends of the proteet⁵ ing pane.

Secured to the outer surface of the window frame 5, are rings 10 which provide supports for the bars 11, the bars being constructed of material such as plastic tubing, asbestos covered ¹⁰ steel, transparent glass, or the like, which will be sufficiently strong to withstand severe pressures thereagainst.

These bars are spaced from the protecting pane 8, there being provided pads 12 disposed 15 between the bars i i and pane 8 to hold the bars 11 with respect to the pane 8 to eliminate vibrations, but at the same time permit a certain amount of movement of the protecting pane to allow for expansion of the protecting pane, due 20 to heat which would be directed thereto, as the result of an exploding bomb in proximity thereto.

Plates 13 are connected with the rings 10 to hold the rings in position.

In the form of the invention as shown by Fig. 3 ²⁵ of the drawings, the frame of the window to be protected is indicated by the reference character 14, and in this form of the invention spaced protecting panes 15 and 16 are provided, the pane 16 being the pane nearest to the window 30 pane 17, and this pane is held in spaced relation therewith by means of the sponge rubber members 18. Of course, this rubber will be preferably silicon plastics which are now used in jet engines for absorbing vibrations.

The protecting pane 15 is spaced from the adjacent protecting pane 16 by means of the strips of sponge rubber 19 arranged at the upper and lower edges thereof, as well as transversely of the protecting pane 15, at its center.

Bars 20 have their ends fitted in ring members 21 that are secured to the frame of the window, the bars providing means to prevent the protecting panes 15 and 16 from becoming displaced, and at the same time allow for expansion of the 45 protecting panes 15 and 16 under intense heat.

As shown by Fig. 4 of the drawings the principle of the invention has been carried out in a divided window structure, in which case pairs of protecting panes indicated at 22, are disposed on 50 the inner sides of the window 23 and are held in spaced relation with each other by the sponge rubber strips 24, the innermost protecting pane 22 being spaced from the window pane 23 by the sponge rubber strips 25.

The opposite or outer sides of the pane sec2,622,285 tions 23 will be protected by the protecting pane 28 which is held spaced from the window pane 23 by sponge rubber strips 27.

The bars 28 which secure the protecting panes in position may be constructed of suitable plastic ₅material, with the ends of the bars held within the rings 29 secured to the window frame. Cushioning members 30 are disposed between the bars and outermost protecting pane 22 to permit of expansion of the protecting panes.

As shown by Fig. 5 of the drawings, an auxiliary frame 30' is provided, the auxiliary frame 30' being recessed to receive the edges of the protecting pane 31 which is held spaced from the window pane 32 by means of the sponge rubber strips 33. This auxiliary frame is also mounted in sponge rubber so that the frame can shift or move as heat expands the shield.

From the foregoing it will be seen that due to the construction shown and described, I have ₂₀provided a protecting means for windows of buildings to absorb shock which would otherwise be directed to the windows, due to pressure directed thereagainst by the explosion of atomic bombs, rockets, and other offense appartus and in- _rcendiaries, as well as a means to stop Are and ‘ damage by the elements.

It will also be seen that the protecting device may be readily and easily mounted on a window and will not in any way interfere with the utility _3tof the window with which the protecting means is used.
