METAL WEATHER-STRIP- SPECIFICA'I'ION forming part of Letters Patent No. 767,286, dated August 9, 1904.

Application filed June 20, 1903. Renewed July 13, 1904. Serial No. 216,355. (No model.)

To all whom it may concern.-

Be it known that I, HUGH E. KENNY, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Metal WVeather-Strips, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an improvement in metal weather-strips, and is embodied in the construction and arrangement of parts presently to be described, and pointed out in the claims.

The invention relates more particularly to that class of weather-strips wherein a flange or strip is secured to one member of a window-frame, projects out therefrom, and works in a groove formed in another member of a window.

Heretofore it has been suggested to make metal weather-strips by bending up a portion into a flange and utilizing the base portion for attaching the strip to the window. It has also been suggested to utilize a singlepiece strip having its edge seated in a groove.

My invention relates more particularly to this latter type of strip, wherein the strip itself has its edge secured in a groove; and it consists more particularly in providing such a strip with outwardly-projecting ears designed to rest on or against the surface of the window member after the edge of the strip has been inserted in the groove and which is also designed for receiving fastening devices, such as tacks or nails.

In the accompanying drawings I have shown a preferred and modified strip; but the constructions are susceptible of various changes and modifications without departing in the least from the principle of the invention.

Figure 1 is a perspective view of a strip. Fig. 2 is a detail cross-section through a portion of a window frame and sash, showing the strip in position. Fig. 3 is an elevation showing the strip applied. Fig. 4 is an elevation showing a modification. Fig. 5 is a crosssection showing an application of the modified'form of strip. Fig. 6 is a cross-section showing another application. Figs. 7, 8, and 9 are a perspective, an elevation, and a crosssection, respectively, of a modified form.

In the drawings, A designates the windowcasing, and B the sash. The casing has intermediate the beads C and C a channel or groove a formed therein.

D designates a metal strip consisting conveniently of a single piece of metal bent back upon itself to form a close U-shaped structure in cross-section. Intermediate the upper and lower edges .of this metal strip are formed transverse ears d. These ears are conveniently constructed by striking them up out of the metal of the strip and are arranged on one side in a staggered position relative to those on the other side for purposes presently to be explained. Y

In application the lower edge of the strip D is inserted in the groove (0 until the under side of the ears d rest on or against the .flat surface of the casing A. While in this position suitable tacks or nails are forced through the projecting ears, and the strip is thereby firmly held in position. By forming the ears on one side out of alinement with those on the other side the openings caused by the striking up of the ears are closed by the adjacent part of the other side of the strip. This is advantageous in that should the lower portion of the strip at any point be of greater width than the depth of the groove the ears can be slightly bent down and secured, as shown in Fig. 6, while the air is prevented from passing through the openings of the strip formed by the striking up of the cars.

In Figs. 7, 8, and 9 is shown'amodified form wherein a single straight strip is employed, the ears being struck up alternately in opposite directions. If necessary, manifestly the ears or securing-flanges may be perforated.

In Figs. 4, 5 I have shown a strip with oppositely-disposed ears, which is shown to indicate that the invention is not limited to the preferred form shown in Figs. 1, 2, and 3.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, .is

1. A metal Weather-strip having securingfianges on opposite sides thereof at points between the opposite edges of the strip.

2. A flat metal Weather-strip having oppositel; eXtending flanges at its sides intermediate its edges.

3. A metal Weather-strip consisting of a flat metal strip having securing-flanges struck up from its sides intermediate its edges and extending in opposite directions.

4. A metal Weather-strip consisting of a folded metal strip having securing-flanges struck up therefrom and arranged at opposite sides out of alinement With each other.

5. In combination With a casing having a groove therein, of a sash having a complementary groove, of a metal Weather -strip having one edge inserted in the casing-groove and one edge inserted in the sash-groove, and

intermediate securing-flanges on the sides of
