WEATHER STRIP.

Application filed March 3, 1922. Serial No. 540,694.

To all whom it may concern.

Be it known that I, ALFRED M. LANE, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Weather Strips, of which the following is a specification.

y invention relates to weather strips.

Heretofore there has been great difficulty in weather-proofing door sills and hinged window sills due partly to the fact that storm water naturally accumulates to a greater or less extent on such sills and is blown through the crack beneath the door or window, and partly alsoto the fact that water-flowing down the side of the frame may be delivered onto the sill back of the sill weather strip. The principal object of the present invention is to overcome this difliculty; and it consists principally in correlating the side strips with the bottom strip .50 that the side strips are located outwardly beyond the bottom strip; and it alsoconsists in equipping the sill with a member comprising an upper strip that is relatively rigid and a lower strip that is resilient, and in equipping the door or sash with av strip adapted to pass between said rigid sill strip and the resilient sill strip beneath the same.

ment lastmentioned together with Weep oles or outlets for deliverin the water outwardly from the engaging strips; it also consists in the arrangement above described together with a wind break on the outer or exposed side of the device; it also consists in the arrangements and combinations of parts hereinafter described and claimed. 1

and

Figs. 6, 7, -8, 9 and 1 0 are views similar I go Fig. 3, showing sill members of modified orm.

Referring to the construction illustrated in Figs. 1 to 3, the sill member comprises a relatively rigid strip 11 and a relatively flexible strip 12. The rigid strip is oflset to form a 2 section and the outer margin or flange thereof is fastened to the sill A while the inner margin is raised above the sill and the middle web portion that connects the two flanges is vertically disposed and providedwith weep holes or outlets 11 near the lower flange. The resilient strip 12 has a flat horizontal portion that rests on the sill underneath the outer flange of the rigid strip, while the inner portion of said flexible strip is curled upwardly and backwardly on itself underneath the inner flange of the rigid strip so. as to form-a resilient hollow bead adapted for yieldable engagement with the under surface of said inner flange when'the sash is in the open position.

Cooperating with the sill member is the sash member, which is made in the form of a relatively flexible flat strip 13, whose body portion slopes upwardly on each side of its middle to form a line contact with the rigid sill member and whose inner margin is re- 7 bent on the underside to form a looprror undercut {groove or pocket 13'. The outer this sash strip is stifl'ene'd by a sharp rebend and is secured to the bottom of the casement'sash or door B at such height that the swinging of the sash will cause the edge of'the rigid sill stri 11 to enter said loop. The free edge of t e loop .enter between the irmer flange of the rigid sill strip 11 and the resilient hollow bead 12 of the flexible sill strip 12, said bead yielding sufliciently to accommodate the entry of the sash strip while holding the free edge thereof in contact with the inner flan e of saidrigid strip. In this construction, the sill strips 11 and 12 are applied to the sill directly and withlivered outside of the sill joint.

out any alteration of the sill; but as the sill strip projects above the sill, the outer bottom portion of the sash B is rabbeted in order that the loop of the sash strip 13 secured to the bottom of the sash may be located at the same height with the raised portion of the rigid sill strip.

The sill joint, formed by the cooperating portions of the sash or door member, the rigid sillstrip and the flexible sill strip, remains waterproof under normal conditions by reason of the three lines of contact between said members. The walls of the pocket portion of the flexible door strip press resiliently upon both sides of the rigid sill strip an and the free edge of the pocket of said flex ible sash or door strip enters between the rigid sill strip and the flexible sill strip whereby a third line of contact is formed, namely between the lower portion of the flexible sash or door strip and the upper portion of the flexible sill strip.

The space between the side rails of the sash B and the sides C of the window frame are weatherproofed by any suitable weather strip, but such strip should be located out wardly with relationto the sill strip; that is, the side strip should be so located that the water draining therefrom should be de- In the construction illustrated in Figs. 1 and 2, the side strip comprises a wide strip 14 of sheet metal whose marginal portions are doubled and which is folded lengthwise near the middle thereof. A fold is made in the form of a tubular bead 14 and the two body portions lie at a considerable inclination to each other. In practice, the side strip is located between the side of the window frame and the sash therein, and is nailed or otherwise secured along one outer margin of the window frame, the other margin being free and adapted to bear resiliently against the side of the casement sash, when the same is closed. As suggested above, the vertical plane of the head 14 of the side strip 14 is located outwardly with relation to the vertical web of the sill strip 11, so that any water that may flow downwardly along said side strip will be delivered into the trough formed by the hollow bead 12 of the flexible sill strip 12 and flow through the outlets 11* onto the sill outside of the weatherproofing joint therefor.

One of the great advantages of the fore- .going construction is that it is not only waterproof under normal conditions but that it remains waterproof against hard rains and driving winds. Under such conditions, there is a tendency for water to pile up on a sill and be forced through the weatherproofing devices. With my construction, however, the force of the wind is broken by the vertical member of the sill thus form two lines of contact;

I ing flange 20 adapted to be strip, that constitutes a wind break or shield, so that the space back of said wind break is comparatively free from the force of the elements. Any water that may be forced in between the sash strip and the rigid sill strip will be delivered into this comparatively, quiet space between the rigid and the resilient strips of the sill member, from which it will pass out throughthe weep holes provided therefor as quickly as conditions permit. v

In the construction illustrated in Fig. 4, the space between the hinged side" of the sash and the window frame is weatherproofed by means of cooperating bead and groove strips of substantially V-shaped section. The bead strip 15 is secured to the window frame and the groove strip is secured within a vertical rabbet formed in the outer edge of the sash in position to straddle or embrace the rib strip in the closed position of the sash. These strips are located outwardly with relation to the sill strip so that water draining therefrom is delivered outside of such sill strip.

In the construction illustrated in Fig. 5, the invention is shown applied to a door. In this construction the sill member comprises a rigid threshold plate 16 and a flexible sill strip 17 The plate 16 is fastened to the sill and has an inwardly projecting horizontal flange 16 spaced above the sill and at such height to be straddled by the loop of the door strip 18 in the closed position of the door. The flexible sill strip 17 is located beneath the plate 16 and has a hollow head 17 located beneath the overhanging flange 16 of the plate 16. The hollow bead 17" at the inner margin of the flexible sill strip 17 is protected against crushing by means of a separate base strip 19 having a flat body portion located beneath the inner marginal portion of the strip 17 and having a rib 19 located outside of nthe beaded portion of said strip. The threshold plate 16 is provided with alined weep holes 16 so that any water delivered to the space between the rigid and resilient strips of the sill member will pass out through said weep holes.

In the construction illustrated in Fig. 6, a rigid door-sill plate 20 has an overhangengaged by the loop of the door strip 21. A flexible sill strip 22 is located between the door sill plate and door sill and has an upwardly inclined beaded outer margin 22 adapted to bear against the loop of the door strip in the closed position of the door. The door sill plate 20 is rovided with suitable weep holes 20 adapte to delived water from the space formed by the cooperating inner marginal portions to the outer side of the door sill.

The construction illustrated in Fig. 7 is similar to the construction illustrated in-Fig.

6, except for a slight difference in the shape of the flexible sill strip, theisill strip 23 shown in Fig. 7 having its inner marginal portion doubled back in the form of a loop 23 which engages the under side of the loop of the flexible door strip.

In the construction illustrated in Fig. 8, the invention is shown in connection with "a casement window. In this construction, the rigid sill strip is shown in the form of a channel strip 24: whose inner wall is provided at its upper edge with an inwardly extending horizontal flange 24 This flange is adapted to be embraced by the loop portion of the flexible sash strip 25 in the closed position of the sash; and the doubled under portion of said loop is adapted to engage the hollow bead 26 of a flexible sill strip 26, whose flat portion is clasped between the rigid-sill strip 24 and the sill. The rigid sill strip is provided with suitable outlets 24 for draining water from the beaded portion of the flexible sill strip onto the outer portion of the sill.

The arrangement shown in Fig. 9 is similar to that shown in Fig. 8, except that the channel shaped sill strip 27 of Fig. 9 differs from the sill strip of Fig. 8 by having its bottom spaced above the flat portion of the flexible strip by means of depending side flanges 27 These flanges areprovided with alined weep holes 27 'for draining the water from the space formed by the inner side of the rigid sill strip and the beaded portion of the flexible sill strip.

In the construction illustrated in Fig. 10, the rigid sill strip is shown inthe form of a flat plate 28 which is secured to the stool D of the sill. This plate overhangs the inner edge of the stool and is adapted to be engaged by the loop portion of the flexible sash strip 29 in the closed position of the sash. The flexible sill strip is shown in the form of a strip 30 of Z-shaped section fitted in the angle between the sill and stool, the top flange of said strip resting on the stool beneath the rigid strip 28 and the bottom flange being curled upwardly and backwardly to form a hollow bead 30 underneath the overhanging portion of the rigid sill strip 28. The stool and the vertical web of the flexible sill strip are provided with registering weep holes 31 for conducting water from the beaded portion of said flexible strip to the outer portion of the sill.

Among the advantages of myinvention is the facility with which it may be applied. In all cases, the two parts forming the sill member may be applied directly without any alteration of the sill; and the only alteration required to be made in the bottom rail to accommodate the resilient strip therefor is to rabbet or groove the outer bottom edge thereof. Likewise, the side strip is very easy of application; as it is merely necessary to strip having an open tubular portion underneath and normally yieldably engaged with said flat portion,l substantially as described.
