Feb. 27, 1934. D. E. ROSS WEATHER STRIPPING Original Filed July 18, 1932 o I S i R I patented Feb. 27, 1934 UNITED STATES PATENT OFFICE WEATHER STRIPPING David E. Ross, La Fayette, Ind., assignor to Rostone, Incorporated, La Fayette, Ind., a corporation of Indiana Claims. (Cl. 189-435) This invention is a division of my application for patent filed July 18, 1932, Serial No. 623,266.

The invention relates to window construction, and its object is to provide novel metallic weather stripping for the window sash, and the like.

I will explain the invention with reference to the accompanying drawing, and summarize in the claims the features and combinations of parts for which protection is desired.

In said drawing: I

Fig. 1 is a vertical section through part of a window frame and sash equipped with my novel weather stripping.

Fig. 2 is an enlarged detail sectional view of the lower part of Fig. 1.

Fig. 3 is a vertical section of a modified form of frame and sash equipped with the weather stripping.

Fig. 4 is a transverse section on the line 44, Fig. 1, with the intermediate sash lowered.

The window frame and glazed window sash shown herein are fully described in the aforesaid parent application and need no detail description herein. Briefly each sash comprises a heavy glass plate enclosed in a suitable frame slidable in the standard ways in the window frame. The sashes are preferably slidably mounted in the metal frame as described in said application, each sash being independently operable.

To the inner face of the guides 7 between the sash may be attached bowed metal strip 700 (see Fig. 4), the edges of which may contact with the glass and act as weather stripping to exclude air and moisture from the interior of the guide.

As shown in Figs. 1, 2 and 3 at the bottom of the sash is a very thin sheet metal strip 15, bent as shown. This strip is preferably of spring material and has two lines of contact with the glass, as shown most clearly in Fig. 2. Welded to this strip 15 is a curved strip 16, which may have fingers 16 on its outer edge. Part 16 is of spring material but much heavier than part 15. This holds the strip 15 rigidly against the glass and moisture can drip out between the fingers of strip 16. These devices form a perfect weather seal.

In the upper part of the frame shown in Fig. 3 are disposed parallel housing sheets I), b, and c, c. Sash W is adapted to enter between sheets I), b and sash W between sheets 0, c.

Disposed over the upper edge of each sash, Fig. 3, is a tubular member 14 of any suitable yieldable material which is adapted to fill the space between the housing sheets and acts as a weather stripping and soundproofing medium.

Within .this tube 14 is placed a resilient liner to hold it concentric, and to allow for the unequal coefficients of expansion of the metals to the glass.

The ways for each sash in Fig. I extend from top to bottom of the frame. Each of the sashes are provided with the lower weather seals 15, 16 as above described and the sashes W and W are each provided on their upper edges, under the rods 4 with a thin bowed metal strip 17 which when the upper sashesare fully raised and the lower sashes fully lowered, contacts with the metal strip 15 on the adjacent sash and forms a close joint (see Fig. 1).

To form the seal between the upper and lower window sash the thin sheet spring material 17 is used which presses against the thin sheet metal strip 15 opposite, as shown in Fig. 1.

In each case the part 16 is fastened to the thin sheet 15 by welding or brazing; and the stiff fingers 16' go up on the glass to hold the spring in position. This permits rain to drip off, and not collect so the water will freeze and rupture the structure.

The low priced but highly efficient weather stripping methods prevent any transmission of outside atmosphere past the glass area and provides a multiple seal for the prevention of conducting either atmospheric or weather conditions from without to within.

I claim:

1. In combination with a glazed sash, a curved metal strip attached to the sash and engaging one face of the sash and a resilient curved strip connected with the first strip and engaging the opposite face of the sash.

2. In combination with a sash, a curved metal strip attached to the lower end of the sash and having both its edges engaging one side of the sash, and a resilient curved strip connected with the first strip and engaging the opposite face of the sash.

3. In combination with a glazed sash; a curved metal strip engaging one face of the glass plate, and a curved strip connected with the first strip and engaging the opposite face of the glass plate.

4. In combination with a sash, a tubular weather strip attached to the upper side thereof, and a curved metal strip attached to the lower side thereof and engaging one face of the sash, and a curved metal strip connected with the latter strip and engaging the opposite face of the sash.

5. In combination with a glazed sash, a tubular weather strip attached to the upper side of the sash; a curved metal strip attached to the lower side of the sash and engaging one face of the glass, and a resilient curved strip connected with the latter strip and engaging the opposite face of the glass.

6. In combination with a glazed sash, a curved resilient metal strip attached to the edge of the sash and engaging the face of the glass and a resilient curved strip connected with the first strip and engaging the opposite face of the glass 7. In combination with a sash having a transverse tie rod at bottom, a curved metal strip ate tached to the lower rod and engaging one face of the glass plate, and a resilient curved strip connected with the first strip and engaging the opposite face of the glass plate.

8. In combination with a sash having trans-. verse tie rods at bottom; a weather strip attached to the side of the sash, and a curved metal strip attached to the lower rod and engaging one face of the glass plate, and a curved metal strip connected with the latter strip and engaging the opposite side of the glass plate.

9. In combination with a glazedsash having transverse tie rods at top and bottom, a tubular weather strip attached to and surrounding the upper tie rod; and a curved metal strip attached to the lower tie rod and. engaging one face of the glass, and a resilient curved strip connected with the latter strip and engaging the opposite face of the glass.

10. In combination with a sash having a transverse tie rod, a tubular weather strip attached to the sash and surrounding said tie rod, said tubular strip being adapted to contact an adjacent side wall to form a seal.

11. In combination with a sash having a tie rod on its upper side, a tubular Weather strip attached to the upper side of the sash and surrounding said tie rod, said tubular strip being adapted to contact an adjacent side wall to form a seal.

12. In combination with a glazed sash having tie rods above and below the glass; a curved weather strip attached to the sash and enclosing the upper tie rod and a curved weather strip attached to the sash and enclosing the lower tie rod.

13. In combination with a glazed sash and tie rods above and below the glass, a curved weather strip attached to the upper side of the sash and enclosing the tie rod and a curved weather strip attached to the lower side of the sash and enclosing the tie rod.

14. In combination with a glazed sash and tie rods above and below the glass, a curved weather strip attached to the upper side of the sash and enclosing the tie rod and a curved weather strip attached to the lower side of the sash and enclosing the tie rod, the edges of the strips engaging opposite faces of the glass.

15. In combination with a sash, a flexible tubular weather strip attached to the upper side of the sash, the sides of the strip projecting beyond the opposite faces of the sash and adapted to contact an adjacent side wall to form a seal.
