Application filerl ilvlarch. 10, 1922-. 1 Series 1 No. 642,684.

To all whom-- it 9.77.0.1 concern Be it;kno.wn thatl, ARrrHuR H. .Knnn. MANN, residing at 6713; Washington Avenue, in the, city of St..Louis and State. of

Missouri, have invented certain .new and useful Improvements in lVeather Strips/of which-thev following is a full, .clear, and exact. description, .such, as will, enable others skilled in. the art. to make .and use: thesame. My invention relates to impryementsin weather strips ,and; more par cularly to weather and:=-water excluding devices as related to casement, or hinged, windows.

In. the weather. proofing of! joi ts; be ween the frames. .anrlsashes 0t oasementwind ws, especially between the fsillsandlgwer na ils, it is common; to.- proiride -ceactingeel nients: n horizontal, dispositionf, xc 111 "o, n weather and to. pro-vines mi yidispnsed elements for the exclusionlo ,-,.v,ater. j By reason of such disposition of elements water om th in erim", may. e he y direct flow, or seepage, be conducted through the joint between the sill and rail.

It is my primary object to provide a weather proofing for windows, of the recited type, comprising elements disposed vertically, and to span the joint between the sill and sash whereby water flow or seepage is conducted across such joint.

A further object of my invention is to provide a weather proofing for casement windows, in which are combined coacting elements forming a horizontal seal for the exclusion of weather, or drafts, and elements forming a vertical water conductor spanning the recited, horizontal weather seal.

My improvements consist in the novel construction, arrangement and combination of parts as hereinafter fully, clearly and concisely described, definitely pointed out in my claims, and illustrated by the accompanying drawing in which.

Fig. 1 is a perspective view of a fragment of the water table and deflector for securement to the lower rail of the window sash.

Fig. 2 is a perspective view of a fragment of the sill strip.

Fig. 3 is a perspective view of a fragment of the sash strip.

Fig. 4 is a transverse sectional elevation showing a sill and sash equipped with the strips as shown in Figs. 1, 2 and 3.

Fig. 5 is a perspective view of a fragment of a water table and deflector for a rabbeted sash, and

Fig. 6 is a view similar to Figzet shown-- ingthe strip of Fig. 5.21s mounted, andin use, zlateterring by. numerals tOihliG drawing? designates; the :sill,; v8 the; stop thereon :9- the lower rail of the sash, and 10 the rabbet of h s slieforfitmen ov mthe st p In my-draavingjlj show; such; parts: in. theircom. men-,usnal arrangement wherein, byire son fihereqn remen of re ativee l; movement of th is sh wr a hs sill, he h i ontal faces of the rabbet iii gt-hesa-sh are spaced relative to the horizontal facesofdhe sill and-stop Th ncited sharing; of the sil -a d sash e ementsieamsaaop n joint-thr ugh which weatherand water; ,may pass fro noutto in.

Foe the exclusion. of-wea-ther, or drafts, .I' Pr i e s plLawhir-zh I- secur to the hsr zonta face of the; stop 8 by means-sncl aS;t e -.12. and .;ivl1 e11 ha aat iteinncr ma gi ..aat ngue.1 prefe a lymesiding. in

a plane above the body of the strip. Secured to the horizontal face of the rabbet, over the stop, is a strip 14, which carries at its inner margin a hook 15 arranged to embrace or surround the tongue, 13 of the described sill strip 11, and to coact therewith to form a seal preventing movement of weather, drafts, or air currents in either direction through the otherwise open joint between the sill and sash.

For the exclusion of water I provide a shield 16, which is supported by the sill and spans the outer mouth or side of the open joint between the sill and sash, as shown in Fig. 4. Obviously water from the exterior is conducted by the shield from above the joint to below the joint.

By preference, the shield is provided with a trough, suchasl'l, and by further preference, as shown best in Fig. 2 the shield and trough are formed as an integral extension of the sill strip 11. At its upper end the shield is bent or inclined inwardly to approximate the sash and thus partially close its otherwise open top.

For the further and fuller closing of the open topped shield I provide a water table 18, in the form of a strip, which is secured to the sash, for movements therewith, having a deflector 19, for residence inside or behind the shield 16, and inclined or bent to parallel the shield and which functions to conduct such water as may enter over the top of the shield to the trough. For drainage of the trough I provide weep holes such as 20.

By preference the upper margin of the water table is bentiinwardly to the end that when desired it may be imbedded in the sash. r v

By further preference the water table comprises a reentrant 21 forming a shed or cover overlying the upper margin of the shield 16. 1

By the construction and arrangement of the described elements it will be apparent that water from the exterior can neither flow nor seep through the joint between the sill and sash.

In the form shown in Figs. 5 and 6 the construction and operation is identical with the described form except for the water table, 18. In this form the re-entrant 21 is shaped for fitment in a rabbet 22 formed in the outer face of the sash.

I claim 1. A weather proofing for casement win dows, comprising an element composed of a shield, a trough and a tongue and arranged for securement to a sill, an element having a hook and arranged for securement to a sash and an element comprising a table, a deflector and a re-entrant portion and arranged for securement to a sash, said tongue and hook adapted to form a weather seal in the joint between the sill and sash and said table, deflector, reentrant, shield and trough adapted to form a water seal for said joint.

2. In a weather proofing for casement windows a strip for securement to the outer face of the window sash, having a deflector inclining downwardly and outwardly and a reentrant forming a shed above said deflector, a second strip for securement to the horizontal face of a rabbet formed in the sash, having a hook at its inner margin, and a third strip having a portion for securement to the horizontal face of a sillstop, a tongue on said portion for engagement in the recited hook, an outstanding trough shaped portion and a shield above the trough-shaped portion inclined inwardly and upwardly to overlie the recited deflector and to underlie said shed.

3. A weather proofing for casement windows comprising a strip for securement to the outer face of a sash, a strip for securement to an underneath face of a sash, and a strip for securement to a sill, said last mentioned strip arranged to co-act with the first mentioned strip to exclude water from the joint between the sash and sill and to co-act with said second mentioned strip to exclude air from said joint.
