WEATHER-STRIP.

Specification of Letters Patent.

Patented Dec. 25, 1906.

To (all whom, it Uta/Z] concern:

Be it known that I, FRANK N UNNING, Jr., a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification.

My invention relates to means for preventing rattle and making a weather-tight joint in windows.

The object of my invention is to provide a simple, durable, and effective device of the above character which maybe readily applied and which will present a neat and linished appearance, requiring no further attention to maintain its efficiency.

My invention consists of a strip of resilient material, preferably of spring-brass or other non-corrosive 1naterialsucl1 as zinc, galvanized iron, or alu1niniumfolded longitudinally and having each of the folds thus formed slightly bent backward longitudinally, whereby a double spring is formed.

Myinvention also consists in the further details and in the improved mode of application, as will be more fully pointed out and claimed herein.

In the drawings which serve to illustrate my invention, Figure l is a sectional perspective view of a windowframe and sash in which the sash is provided with my improved weather-strip. Fig. 2 is a plan view of my invention before it is applied to the sash, serving to illustrate the method of folding and bending the strip longitudinally in order to form the double spring above mentioned. Fig. 3 is a perspective view of a portion of my invention. Fig. 4 is a cross-section through the window-frame, sash, and my improved weather-strip, which has been ap plied to the sash.

The preferred construction of my invention is as follows: A strip of the material is folded longitudinally at 1 to form the two spring members 2 and 3. The spring member 2 is bent backward longitudinally at a point 4 near the fold l and the spring member 3 is to a less degree bent backward at a point 5 near the free edge of the member. The two spring members between the points 1 and 4 are substantially parallel, as is seen at 6, and I prefer to form openings, as at 7, through the parallel portions of the spring members, through which a suitable fastening,

either a screw or a nail, as is shown at 8 in Fig. 4, may be inserted into the stile 9 of the sash to which my improved weather-strip is applied. This fastening is driven firmly against the outer member of the strip. The fastening being applied near the fold 1 and through the parallel portions of the spring members, while it holds the strip firmly upon the sash, does not interfere with the proper action of the spring members and is at the same time out of the way of the stop-bead 10, between which and the stile 9 of the sash the spring members 2 and 3 are compressed in degree inversely proportional to the amount of space that happens to exist between said stop and said sash in the particular window to which the weather-strip is applied and by their reaction exert a pressure which tends to hold the sash outward against the parting bead 11, thus avoiding any useless play of the sash within the window-frame and preventing the annoying rattle of the window by the action of the wind against it or any other disturbing cause. Since the spring member 3 is longitudinally parallel with the stopbead and forms a close bearing of considerable extent therewith at all times, as may be seen at 12 in Fig. 4 of the drawings, my improved weather-strip serves the further purpose of making a weather-tight joint when applied as herein described. The spring member is bent backward at 5 in order to remove the hearing-point between the spring member and the stop-bead 10 from the edge of the spring member, and thus provide a proper bearing-surface, as indicated at 12.

The raising and lowering of the sash has no effect upon the proper working of the spring members and the wcather-strip will be found not to vary in its effectiveness regardless of the frequency of the opening and closing of the window.

\Vhile my improved weather-strip will be found to completely close all cracks or openings, it necessitates absolutely no constructive change in the sash or their frames and no special form of pulley or other modification of the fittings of the window and does not cover up the pocket or in any way interfere with the sash-balance. It will also be found to add largely to the finished appearance of the window, owing to its simplicity of construction.

\Vhile I have shown and described my improved weather-strip as being ap lied to the lower sash of the window, it shou d be understood that it is equally applicable to the u per sash and would be applied in precise y the same manner, the action of the spring members taking place between the upper sash and the parting-bead 11, forcing the upper sash outward against the outer bead 13, and any statement made in connection with the above description of its application I to the lower sash would also apply to a description of its use upon the upper sash.

I claim- 1. In a weather-strip, a strip of resilient material folded longitudinally to form two.

spring members being bent backward at a point near the fold thus formed whereby said spring members are maintained substantially parallel between said fold and said point'and means for attaching said strip within said parallel portion.

3. A strip of resilient material folded longitudinally and secured in operative position near its folded edge and having two free edges each adapted to exert pressure laterally from the other to engage a window-frame and sash respectively.

4. In a weather-strip a strip of resilient material folded longitudinally upon itself whereby two spring members are formed, and ada ted to exert ressure laterally from each ot er against t e window-frame and sash respectively between which they are adapted to fit and be moved, one of said spring members being bent backward at a point near the fold thus formed whereby said members are maintained substantially paral lel between said fold and said point, and the other one of said spring members being bent backward at a point near its free edge as and for the purpose herein specified.
