WEATHER STRIP.

Application fled October 28, 1925. Sex-18.1110. 64,810.

To all whom it may concern:

Be it known that I, HANS. CHRISTENSEN, a citizen of the United States, residing at the city and county of Denver, andState of Colorado, have invented certain new and useful Improvements in Weather Stnps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in weatherstrips.

The necessity of closing the cracks about doors and windows so as to exclude cold air,

dust and 'snow has long been recognized and many different forms of weatherstrips have been made and sold.

It is the object of this invention to produce a Weatherstrip of a simple construction that can be cheaply made and quickly applied and which shall have a neat appearance and perform its function satisfactorily.

The Weatherstrip that forms the subject of this invention is made of rubber or rubber composition reenforced with fabric and can best be described when reference is had to the accompanyingdrawing in which the preferred embodiment has beenjllustrated and in which: a Fig. 1 is a perspective view showing a'section of the'weatherstrip in place on a door frame; Fig. 2' is a section Fig. 1; Fig. 3 is a section similar to that shown in Fig. 2 but showing the door closed, and Fig. 4 is a transverse section of the Weatherstrip.

Numeral 1 represents the flange of a door frame against which the door abuts when in closed position and may also be considered as representing the stop strip of a window, and 2 represents a door or window frame. In Fig. 3 the door has been shown closed. The Weatherstrip is formed from moulded rubber and its novelty resides in its peculiar cross section which has been clearly shown in Fig. 4. The body portion 3 of the strip taken on line 2-2,

has a sector shaped cross section and extends 104 in the manner shown in Fig. 4. One side is extended so as to form" a thin flap 4 that lies in the plane of the corresponding sides'of the body portion. A canvas strip 5 is vulcanized to the flap 4 and the side of the body member 3. As the body portion 3 has an angular extend of 140 the side 6 will make an angle of 76 with the plane of the flap 4. When the strip is appliedto the door frame, the angle between sides 4 and 6 will be changed to 90 and this will cause the side 70f the body member that was originally in the plane of the flap 4 to be bent towards the door at an angle of 14. When the door is closed (Fig. 3) it will engage the corner of the Weatherstrip and compress the same until its angular extent will be 90 thereby making a tight seal between the door and the body member.

If the Weatherstrip is employed in connection with a window, the sealing action will be the same.

It is apparent that the Weatherstrip above described will produce a very satisfactor seal and that it is conveniently applie Particular attention is called -to the fact that. the body portion 3 is compressed and not merely bent; this produces a better sealing action than if the material were merely bent. Attention is further called to the fact that the flange 4 and the side 7 are normally in the same plane and that side 6 forms an acute angle with the flange 4. By this construction a strip is produced that can be more readily and side 7 were normally in angularly related planes and the angle between side 6 and flange 4 a right angle,

Although the weatherstrip has been shown attached to a. door frame, it is evident that it can be used on ordinary windows and casement windows as well.

Having now described my invention whatis claimed as new is:

1. A weather strip adapted to be attached to a piece having a rectangular corner, consisting of apiece of rubber composition having a cross section comprising a body portion of sector shape and of an angular extent greaterthan 90, said body portion having one side extending across the center point moulded than if the flange 4 in the same plane whereby the angle between the other side and said flange will be less than 90. 7

2. A weather strip adapted to be attached 5 toa rectangularpiece and to fit about one corner of the same, said strip having a sector shaped body portion of an angular extent of approximately 104 one side of said body member having a flange formed integral therewith and extending in the same direc- 1 tion.

In testimony whereof I have afiixed my signature. I i HANS CHRISTENSEIL"
