WEATHER STRIP.

Application filed November 6, 1928. Serial No. 317,656.

The present invention relates to weatherstripto be used in connection with windows or the like and to be attached in the window frame in a manner to render the same inconspicuous and at the same time effectivein the prevention of drafts.

The device is in the nature of a thin strip of material bent in a manner to effectively seal the space around a window frame and between the same and the window casing.

Objects of the invention are to provide a device of this character which shall be simple in construction, inexpensive to manufacture, easy to install and which, while effectively sealing the space as stated above will not foul as a result of the contact with the window frame thereagainst, and will not be distorted from its effective shape by such contact.

A further object of the device is to provide a mechanism that can be applied in any position and to any condition met in connec tion with windows or other closures to be weather-stripped.

The above objects may be accomplished by forming a trough-like member of thin resilient sheet metal and bending the edges of the trough-like member laterally at a slight angle to the sides of the trough. The trough itself is formed by providing a longitudinal bend in the material preferably centrally located relative thereto, and forming the sides of the trough so as to spread at a wide angle to each other on the concave side of the strip. A further object of the device is to provide a mechanism that can be applied in any position and in any condition met in con nection with windows or other closures to be weather-stripped.

In the drawings,

Figure 1 is a perspective view of a por tion of a Weatherstrip made in accordance with the present invention, and

Figure 2 is a section transversely of the groove in a window frame and showing fragmentarily a part of a window sash therein with the present invention located in one position it may assume relative thereto.

Figure 3 is a section similar to Figure 2. showing a somewhat different application of applicants invention to a door frame.

Referring to the drawings in detail by reference characters, 5 designates in general the weather-strip which is comprised of two portions "6 and 7 joined on a medial line 8 and flaring laterally therefrom at a-comparatively wide angle.

The strip, as stated above, is preferably made of resilient thin sheet metal as of tempered spring bronze or the like, and the side portions 6 and 7 are bent near to and parallel with their edges along lines 9 and 10, the angle made at this point being also wide as between the portions 6 and 7 and the portions 11 and 12. By this construction, yieldable members are provided which will give under the pressure of the window sash when the same is projected into the groove 13 of the frlzltme or into the recess or offset 14 of the s1 The slightness of the angle between the portions 6 and 7 and 11 and 12, respectively, will insure against the fouling of the weather-stripping with either the window or the window frame and eliminate the deformation of the strip owing to pressure exerted thereupon. The weather-stripping may be secured to the window frame in any suitable manner, as by tacks, one of Which is shown at 15 which may be located alongthe centerline 8 or may be extended through one of the sides 6 or 7 as shown at 16.

In Figure 3 in the latter arrangement, one of the sides 6 or 7, as the case may be, through which the tack is driven will rest substantially flat against the sill or frame of the window or in the offset of a door jamb while the other side will extend upwardly therefrom in a position to abut the window sash.

A feature of the invention is the slightness of the angles in the device which construction affords easily yielding of the stripping to force exerted thereon, while at the same time preventing projection of the sharp edges of the stripping into the material of the win dow sash with a consequent fouling and deformation of the stripping which, in ordinary proceedings, renders the weather-stripping ineffective.

The slight angles along the lines 9 and 10 also adapts the device for use in a plurality of situations, two of which are illustrated in the drawings.

The weather-strip herein described and illustrated may be changed in various details from the embodiment hereinbefore disclosed within the scope of the invention as set forth in the specification and as hereinafter claimed.

I claim 1. As an article of manufacture a weatherstrip of resilient material having side members arranged at a Wide angle to each other and having the material thereof adjacent the side edges rearwardly bent at an angle of more than 90.

2. An article of manufacture comprising a weather-strip adapted for a variety of applications and consisting of a trough-like member the sides of which flare laterallv outward at an angle of more than 90 and are provided marginally with rearwardly bent portions, the angle of said last named por tions of the sides of the trough-like member being substantially the same as that between the side members and means for securing the stripping to a window frame.

3. A weather-strip consisting of a strip of resilient material having a plurality of an gular bends opening alternately in reverse directions, the angles between adjacent portions being greater than 90.

In testimony whereof I have signed my name to this specification.

CHARLES MoVEETY.
