FRANK REESE, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO REESE WEATHER STRIP 00., OF MINNEAPOLIS, MINNESOTA, A CORPORATION OF MINNESOTA WEATHER srnrr non. CASEMENT wrnnow B'io'r'roras AND sI LLs Application filed February 10, i930. Serial no; 427,354. 7

My present invention has for its objectthe provision of a simple and highly efficient weather strip for a casement window bottom and sill to form a weather-tight joint therebetween and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawing, which illustrates the invention, like characters indicate like parts throughout the several views.

Referring to the drawing:

Fig. 1 is a fragmentary view of a casement window frame to the sill of which the improved weather strip is applied; 6

Figs. 2 and 3 are fragmentary detail views principally in section taken on the lines 2-2 and 33 of Fig. 1, respectively, and further showing a casement window in said frame;

Fig. 4 is a sectional perspective view of the flashing; and

Fig. 5 is a sectional perspective view of the sill member turned bottom side up.

The numeral 6 indicates, as an entirety, a casement window frame with the exception of its sill 7 and the numeral 8 indicates a casement window hinged to said frame for in-;

' rolled to form a relatively large tubular bead 12 under the window 8 with its axis substan tially in the plane of the inner face of said window. It will be noted that there is a slight clearance between the bottom of the window 8 and bead 12 for the passage of water therebetween.

Resting on the flashing 11 is a sill weather strip member 13 that is channelshaped in cross-section and has on its bottom, at its sides, inner and outer beads 14 and 15. respectively, which extend the full length of said member. These beads 14 and 15 are on the under side of the member 13 and support the bottom thereof above the flashing 11. Internally the bead 15 is channel-shaped in cross-section and affords a water-collecting groove 16. It is important to note that the bead 1 1 is slightly higher than the'bead 15 and holds the bottom of the member 13.

transversely inclined so as todrain into the groove 16. The inner side of'the member 13, at its upper portion, is bent laterally away from said member and folded upon itself to form a horizontal tongue 17. i

The outer side member 13 is curved inwardly and its upper longitudinal edge is arranged to be engaged by the window 8 in the corner of its rabbet 10 whensaid window is closed to form a tight joint therebetween. to form a weather-tight joint between the sill 7 and bottom of thewindow 8, is a hook-' member 18within the rabbet 9 and nailed to the bottom of said window. This hook-member 18 is arranged to yieldingly receive the tongue 17 when the window is closed.

. Formed in the outer side of the member 13 is a plurality of longitudinally spaced weep holes 19 formed by longitudinally slitting in said side at the bottom of the groove 16. The outer side of the member 13, above the weep holes .19, is pressed laterally outward to form hoods 20 over said weep holes.

In case water should enter the channel member 13, between. the outer side thereof and the window 8, the same will be collected in the roove 16 and escape through the weep holes 19 onto the sill 7 outside of the buildmg.

Formed in the bottoms of the beads 14 and 15are weep holes 21 for the escape of Water due to condensation on the inside of the window 8. In case water should collect on the inside of the window 8 the same will run down said window onto the bottom thereof over the bead 12 and be precipitated onto the flashing 11 where the same will flow through the weep holes 21 and onto the sill 7 at the exterior of the building.

The channel member 13 and flashing 11 are rigidly secured to the sill 7 by screws 22 passed through aligned holes in the bottom of said member and flashing. The hooks 20 prevent water splashing on the sill 7 from entering the weep holes 19 and also cover the Cooperating with the tongue 17 weep holes so that they are not exposed to View. The bead 12 gives the inner edge portion of the flashing 11 a finished appearance and substantially closes the opening between the sill 7 and bottom of the window 8. This bead 12 does not interfere with the flow of water, which may collect on the inside of the window 8, onto the bottom of said window where the same is precipitated onto the flashing 11 and escapes, as previously described.

What I claim is:

1. A weather strip for a casement window including a sill channel member having on its bottom depending inner and outer'longitudinal beads arranged to rest on a window sill and support said member thereabove with clearance the full distance between the beads, said outer bead being shaped to form a water collecting groove in thesill member, the bottom of the sill member being inclined to drain into said groove, and weep holes at least one of which is in the sill member and extends into said groove to cause the same to drain outside of the sill member, and the others of which are in the two heads.

2. The combination with a casement window and a sill therefor, of a flashing on the sill having an upstanding bead on its inner longitudinal edge substantially directly under the inner face of the window, a Weather strip including a sill member on the flashing and having on its inner longitudinal edge a laterally projecting tongue, the inner edge of the tongue being spaced from the bead on the flashing, whereby moisture on the inner face of the window will be precipitated between the bead and tongue and onto the flashing, and a hook-like member on the window arranged to receive the tongue on the sill member when the window is closed.

3. A weather strip for a casement window including a sill channel member having on its bottom depending lnner and outer longitudinal beads arranged to rest on a window sill and support said member there'above' with clearance the full distance between the beads, said outer bead being shaped to form a water collecting groove in the sill member, and weep holes at least one of which is in the sill member and extends into said groove to cause the same to drain outside of the sill member, and the others of which are in the two beads.

In testimony whereof I affix my signature.
