WEATHER-STRIP.

i ,esige/asi.

To r/ZZ "whom 'it may concern Be it known that l, HARRY H. SCHROYER, a citizen of the United States, and a.resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new 'and useful Improvements in leather-Strips; andi do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

This vinvention relates to new .and useful ii proveniente in weather strips, and although applicable for general use, is shown more particularly embodied as a weather strip or guard for car windows.

it is an important object of this invention to provide a weather strip adapted to prevent air, or dust from entering between the lower rail and the s'ill of the window when the sash is closed.

t also an object of this invention to Aprovide a flexible fabric sealing means adapted to seal the space between the sash rail and the sill along a plurality of lines.

It is also an object of this invention to provide a weather strip in which the weight of the sliding sash and the wind pressure thereonserves to make the sal more effective.

It is finally an important object of this invention to provide a simple, durable and inexpensive weather strip adaptable'to any ordinary sash without alteration thereof and to afford an effectual seal therefor.

The invention (in a preferred form) consists in the matters hereinafter described. and more fully pointed out and defined in the appended claims.

In the drawings: Figure l is a fragmentary View in elevation illustra-ting' the outside of a car window equipped with a device embodying the principles of my invention.

Fig. 2 is an enlarged fragmentary section through the sash ails and sill thereof. Fig. 3 is an enlarged detail View in section of the lower sash rail and the sill with the weather -stripping engaged therebetween. Fig. 4 is an enlarged sectional View of the lower rail of the Window sash,illustrating the operation of,I the weather stripping wb the window rail is out of contact with Specification of Letters Patent." Patented A131', 28,` 191.1, Application filed March 12,

191s. serial 1go, 753,760.'

sill. Fig. 5v is a' fragmentaryy bottom plan View of the Window rail with the weather stripping secured thereon.

'As shown in the drawings: the reference numeral'l indicates an ordinary sloping voutside window sill of a carwindow secured 1n a suitable manner to an inside sill num- 4 bered as 2. As Ashown in F ig. 2, the car' window consists of a double sash comprising an inner and outer sliding sash member numbered. as 3 and 4, respectively. The weather stripping ine-ans is secured on the lower rail of the outer sash and comprises a base plate 5, secured to the lower face of the sash rail, and,'if desired, said plate is folded over and back upon itself as shown,

at G. The other edge of said plate is bent at an .acute angle as shown at 7, for a purpose hereinafter set forth. A strip of tallowstaked or otherwise impregnated felt 8is secured tightly against said plate 5, by means' of a metall-ic strip 9, which is secured to and through the plate 5, and into the sash rail li, by means of the screws l0. Said strip of fabric, as shown,`is of such a vlength as to affordl depending 'ends 1l and l2, which serre to seal the rail and sill at two points.

The operation is as follows: As shown in the. drawings, the lower rails of the sliding sashes are faced at an angle to correspond with the slope of the sill member l. .Vhen

the sash is opened the depending edges il and 12,' of the fabric hang slightly inclined from perpendicular,l the slight stiffness of the fabric tending to hold the edge il, slightly outwardly and the acute angled flange 7, of the plate 5, serving to bend the edge, l2, of the fabric in substantially.paral lel relation with the depending edge 1i..

-Vhen the window sash is closed, as the rail 3 approaches the sill, the edge l2 of the fabric striking the surface of the sill is directed beneath the plate 9, while the edge 11, being similarly directedJ is thrust outwardly andv extends for a short distance downwardly on the face of the sill'. Thus it isjseen that the weight of the' sashfserves of the fabric extending outwardly as it does upon the sill, due to its slight stiffness, bears ..upon the same in close relation, but' the contact pressure thereof upon the sillis more importantly and further augmented by the pressure of the Wind acting upon the same when the train is in motion.

Of course, details of construction are open to wide variation without departing from the principles of this invention, and I therefore `do not purpose limiting the patent granted otherwise than necessitated by' the prior art.

I claim as' my invention:

1. In a device ofthe class described, a base plate adapted to be secured to the lower rail of a sash and having an angled flange vai one edge thereof, a strip .secured to` szud base plate, and a piece of fabric secured ,between said base plate and strip with its edges depending, said angled flange directing one of said depending edges inward be- -ncath said strip, and said other edge heilig left, free to project beyond the sashA rail.

'2. In va 'device of the classdescribed, a base plate adapted to be secured to the lower edge of a sash and coextensivein width therewith and having an angled flange at the inner edge thereof, a narrower stripsecured to said base plate, and a piece of fabric secured between said base plate and .strip with its edges depending, said angled flange directing one of said depending edges inward beneath said strip, and seid other edge beipg left free to project beyond the sash ral In testimony whereof I have hereunto subscribed my name in the presence oftwo subseribing Witnesses.
