CARL 3'. LINDQUTST, OF NEW YORK. N. Y.

WEATHER STRIP.

Application filed February 16, 1923. Serial No. 619,335.

To all whom it may concern.

Be it known that I, CARL J. LINDQUIST, a citizen of the United States of America, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Weather Strips, of which the following is a specification.

This invention relates to improvements in window constructions and in particular to weather strips therefor of a novel type.

An object of the invention is to provide on the parting strip an improved weather strip which will extend into grooves on the adjacent sashes, the strip being so constructed and designed as to provide a rain shield and which will at the same time, when in position, conceal the groove. My improved strip can be applied without removing the sashes.

A further object of the invention is to provide a weather strip which will not deteriorate with time or change its shape due to atmospheric conditions, the longitudinal corrugations tending to maintain the strip in proper shape at all times and the strip having sufiicient resiliency to accommodate itself to irregularities in the grooves or warping of the sashes.

Referring to the drawing, wherein several embodiments of my invention are disclosed;

Fig. 1 is a sectional plan view taken through a sash showing the application of my improved weather-strip thereto;

Fig. 2 is a view of a part of Fig. 1 showing the application thereto of a modified form of weather strip;

Fig. 3 is an enlarged top plan view of a portion of a weather strip showing its engagement with a groove in a sash; and

Fig. 4: is a view in perspective of a piece of Weatherstrip which has incorporated therein a filler of felt or rubber.

Referring to the drawings in detail, 5 indicates the lower sash of a window which has sliding movement in a well known manner between the sash stops 6 and parting strips 7, the two being joined by the usual pulley stiles 8 which border the edges of both the lower and upper sashes. The parting strips 7 separate the sashes and a description of my invention as applied to one parting strip and one side of one sash will serve to illustrate its use.

The spaces between the sash and the frame of the window admits air and rain if there is no method used of sealing the same, and

my weather strip 9 when applied as shown in Figs. 1, 2 and 3 prevents admission of air and rain and also besides concealing the groove cut in the sash takes up wear of the edges of said groove.

In the form of Weatherstrip shown in Figs. 1 and 3, T provide a strip of metal 9, such as zinc or copper which is not liable to corrosion and which is bent adjacent its longitudinal edges to provide corrugations or ridges 10, one of which is or may be disposed on each side of the parting strip 7 when the Weatherstrip is attached thereto by nails 11 as indicated.

Suitable grooves 12 are provided in the sashes adjacent the parting strips 7 into which extend the edges of the weatherstrips 9, until the corrugations 10 thereof rest on the edges of the grooves as shown in Fig. 3 to seal and conceal the same and thus provide a closure for the space between the sash and frame.

As shown in Fig. 2, I may provide the edges of the strip 9 with beads 13 which are formed by bending the strip edge over to fo m an enlarged loop. These beads are disposed within the grooves and engage the side walls of the latter, thus more effectively sealing the opening between the frame and the sash.

In Fig. 4t I have shown a piece of a strip similar to the one having the beads 18 thereon, with the exception that this strip is pro vided with a filler or backing 1a, the edges of which are held under the beaded edges 13 of the Weatherstrip 9. This filler may be of rubber or felt.

The strips 9 may be fastened to each parting strip 7 and engage grooves in the lower and upper sash simultaneously, so that both sashes are maintained weatherproof.

It can be readily seen that the weatherstrips can be applied to the sashes without removing any part of the window framing or structure and are simply nailed to the parting strip and extend the length thereof. The strips 9 are provided with suitable nail holes 15 in manufacture which facilitates their being applied.

Any shrinkage of the sashes or structure to which the strip is attached is taken up, as the corrugated portion of the strip is sufficiently wide to always be self-seating on the groove edge and therefore seal the same.

What I claim is:

1. In combination, a parting strip of a Window construction, sash stiles coacting therewith, said stiles having grooves therein, a Weatherstrip attached to said parting strip and engaging the grooves in said stiles and said Weatherstrip having angular ridges there-in each engaging an edge of the adjacent one of the grooves in said stiles.

2. In combination, a parting strip of a window construction, sash stiles coacting therewith, said stiles having grooves there in, a Weatherstrip attached to said parting strip and engaging the grooves in said stiles, and said Weatherstrip having angular ridges therein, and beads formed on the edges thereof, said beads lying Within said grooves aid said angular portions each en aging an dge of the adjacent one of the grooves in saic stiles.

3. In combination, a parting strip of a n ndow construction, sash stiles coaoting 20 7; herewith, said stiles having grooves there- 11. a Weatherstrip attached to said parting strip and engaging the grooves in said stiles,
