WEATHERSTRIP CONSTRUCTION FOR WINDOW SASHES Filed July 1, 1929 QZ W lNVE OR ATTORN EYS Patented Apr. 7,' 1931 UNITED STATES PATENT OFFICE HOWARD A. CBONMILLER AND EDWARD F. CHAFFEE, OF SYRACUSE, NEW YORK, AS- SIGNORS TO THE 0. M. EDWARDS COMPANY INC., OF SYRACUSE, NEW YORK, A GOR- IPORATION OF NEW YORK WEATHER-STRIP CONSTRUCTION FOR WINDOW SASHES Applicationfiled July 1, 1929. Serial No. 375,180.

This invention relates to window sashes and has for its object, a weather strip for the bottom rail of the sash, which weather strip is yielding or resilient and shaped to conform to an inclined window sill when the sash is lowered against the sill to conform for irregularities in the sill surface.

, The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is made 'to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is afragmentary elevation of a window sash embodying this invention.

Figure 2 is an edge view of parts seen in Figure 1 and the contiguous portion of the sill, the sash being shown in its closed position with the weather strip compressed against the sill.

Figure 3 is a view similar to Figure 2 showing the sash as away from the sill and the weather strip in its normal form.

The sash may be of any suitable form, size and construction and includes the usual stiles, rails and glass pane.

It will be understood that the sash is guided during its raising and lowering move ment in the window frame in any suitable manner.

1, 2 and 3 designate respectively, one of the stiles, the bottom rail and the glass pane.

4: designates the sill which is shaped to provide a stop at 5 at the inner surface of the bottom rail when the sash is closed and with an outwardly and usually downwardly slopof the bottom rail and provided with inturned flanges 8. The construction of the bottom rail forms no part of this invention.

9 designates the weather strip which extends lengthwise of the lower edge of the bottom rail. The weather strip here shown includes a base portion 10 which is enclosed in a metal casing 11, in the form of an inverted channel, the side walls of the channel having inwardly extending flanges 12 which slidably fit channels formed by bending back the inturlngd flange 8 of the side walls of the bottom rai The weather strip is inserted in the bottom rail by an endwise sliding movement. This feature forms no part of this invention.

The base 10 is formed with grooves in its side faces for receiving the inturned flanges 8. The construction thus far described forms no part of this invention.

The portion of the weather strip below the bottom rail is formed hollow and of a general triangular shape in cross section, the hypotenuse of the triangular formation being are shaped providing an are shaped outer wall 13 which engages the surface 6 of the sill, one of the legs of the triangle abutting against theinternal flanges 8 at the lower edge of the bottom rail 2, and the other leg 14 of the triangular formation being parallel to the outer face of one of the side walls of the bottom rail and preferably flush therewith. The internal cavity 15 of the weather strip is also triangular in general form with a wall with the hypotenuse thereof substantially parallel to the outer wall 13 of the weather strip and the wall 16 along one of the legs of the triangular formation opposed to the plane of the lower edge of the bottom rail parallel to the third wall 17 of the triangular formation extending in the same direction as the outer wall 14 of the weather strip but normally inclined out of a plane parallel to the wall 14, the inclination being upwardly away I from such wall 13, so that the upright wall 14 is thicker at its top and bottom.

The upright wall 14 is thicker and more rigid than the hypotenuse wall 13.

Owing to the shape of the lower portion 8 of the weather strip and the formation of the to the surface 5 of the sill and to any irregularities therein due to any particles of dirt 'ete., adhering thereto so that the sash is weather tight along the bottom rail, when i I closed and also owing to the wall 14: and its formation, it yields slightly outwardly, (Figure 2) when the wall 13 is compressed, so that the nose at the angle of the two walls is forced outwardly against the guide strip 4* when the sash is closed and prevents the accumulation of dust that would otherwise occur in the pockets at the, ends of the weather strip 1n the guides 45* whereby dust works under the Weatherstrip under the force of the wind created by the train in motion.

What we claim is:

1. A window sash having a weather strip along the edge of its bottom rail for coacting with the sill of the window frame, said weather strip being formed of resilient material and formed hollow and having its lower sill engaging surface inclined and one of its outer surfaces vertical and located in the plane of one side face of the bottom rail.

2. A window sash having a weather strlp along the edge of its bottom rail for coacting with the sill of the window frame, said weather strip being formed of resilient material and formed hollow and having its lower sill engaging surface inclined and one of its outer surfaces vertical and located in the plane of one side face of the bottom rail, the

wall on which said lower surface is formedbeing flexible and the wall on which said upright surface is provided being arranged to receive compression force when the sash is against the sill.

3. A window sash having a weather strip along the edge of its bottom rail for coacting with the sill of the window frame, said weather strip being formed of resilient material and formed hollow and having its lower sill engaging surface inclined and one of its outer surfaces vertical and the internal cavity of the weather strip being normally of general triangular form with the wall thereof at the hypotenuse of the triangular formation substantially parallel to the sill engaging surface of the weather strip.

4. A window sash having a weather strip along the edge of its bottom rail for coacting with the sill of the window frame, said weather strip being formed of resilient material and having a triangular portion formed hollow and having its lower sill engaging wall inclined and one of its outer walls upright.

5. A window sash having a weather strip along the edge of its bottom rail for'coacting with the sill of the window frame, .said weather strip being formed of resilient material, the portion of the weather strip below the bottom rail being hollow and triangular in general form with the hypotenuse of the triangular formation normally are shaped and one of the legs of the triangular formation abutting against the edge of the bottom rail and the other leg located in the plane of one of the side faces of the bottom rail to present a continuous surface flush with said side face of the bottom rail.

6. A window sash-having a weather strip along the edge of its bottom rail for coacting with the sill of the window frame, said weather strip being formed of resilient material, the portion of the weather strip below the bottom rail being hollow and triangular in general form with the hypotenuse of the triangular formation normally are shaped and one of the legs of the triangular formation being horizontal and abutting against the edge of the bottom rail and the other leg being upri ht and located substantially in the plane of one of the side faces of the bottom rail, the internal cavity of the weather, strip being located in the triangular portion of the weather strip and being also triangular in general form with the hypotenuse of the triangular formation substantially parallel to the outer curved face of the weather strip.

7. A window sash having a weather strip along the edge of its bottom rail for coacting with the sill of the window frame, said weather. strip being formed of resilient material, the portion of the weather strip below the bottom rail being hollow and triangular in general form with the hypotenuse of the triangular formation normally are shaped and one of the legs of the triangular formation being horizontal and abutting againstthe edge of the bottom rail and the other leg being upright and located substantially in the plane of one of the side faces of the bottom wall, the internal cavit of the weather strip being located in the triangular portion of the weather strip and being also triangular in general form with the hypotenuse of the triangular formation substantially parallel to the outer curved face of the weather strip, the upright wall of the triangular formation being thicker than the hypotenuse wall.

8. A window sash having a weather stripof the weather strip and being also triangu- 13o lar in general form with the hypotenuse of the triangular formation substantially parallel to the outer curved face of the weather strip, the upright wall of thetriangular formation being thicker than the hypotenuse wall and thicker at its top than at its bottom.

9. A window sash having a weather strip along the edge of its bottom rail for coacting with the sill of the window frame, said weather strip being formed of resilient material and being of hollow formation, a lower sill engaging wall located below said hollow portion, and an upright wall located in front of said hollow portion and of heavier cross section than the sill engaging wall for carrying the weight of the sash with little flexing of the upright wall.

In testimony whereof, we have hereunto signed our names, at Syracuse, in the county of Onondaga and State of New York, this 22nd day of June, 1929.
