PETER L. HEDBERG, OF CHICAGO, ILLINOIS, ASSIGNOE T0 CHICAGO IVIETAL WEATHER STRIP COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

METAL WEATHER-STRIP.

Specification of Letters Patent.

Patented J une 28, 19M).

To all whom t may concern:

Be it known that I, PETER L. I-IEDBERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal leather-Strips, of which the following is a specification.

This invention relates to improvements in metal weather strips, which are more particularly adapted for use on window frames and in the guide ways for the sashes thereof, yet are applicable also for door frames, and it consists in certain peculiarities of the construction, novel arrangement and operation of the parts thereof, as will be hereinafter more fully set forth andV specifically claimed.

The main object of the invention is to provide weather strips which are principally designed to be secured to the uprights of the window frames, and extended into the guide ways for the sashes thereof, and which shall be of such constri'ictioi'i as to prevent the passage of air, dust, rain, snow and moisture between the parts of the window frame and sashes, as well as to co-act with the sashes or other elements within the frame in such a manner as to prevent rattling, and to compensate for any inequalities due to warpage or shrinkage.

Another object of the invention is to provide a weather strip which may be applied to the top or bottom of the frame in such a manner as to prevent the passage of air, rain and moisture between the upper and lower rails of the sash frames.

Various other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains, to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1, is a horizontal sectional view of a portion of a window frame, and a part of the sashes thereof showing them equipped with metallic weather strips embodying one4 form of the invention. Fig. 2, is a detached perspective view of apart of one of the weather' strips employed in the construction illustrated in Fig. 1. Fig. 3, is a view partly in cross section and partly in elevation of the lower portionl of the window frame showing a modification in the construction of the weather strip as applied to the window sill. Fig. 4, is a detached perspective view of a portion of the strip of the construction shown in Fig. 3. Fig. 5, is a horizontal sectional view of a portion of a window frame and a part of one of the sashes thereof, illustrating another modified form of the weather strip mounted thereon. Fig. 6, is a detached perspective View of a part of the strip of the construction shown in Fig. 5.

Like numerals of reference, refer to the corresponding parts throughout the different views of the drawing.

The reference numeral 10, designates a portion of one of the uprights or side pieces of a window frame which may be provided as usual with a parting-stop 11, an inside stop 12, and an outside stop 13, which stops provide guide ways for the side stiles 14, of the sashes.

Referring now, to Figs. 1, and 2, of the drawing, the reference numeral 15, designates one of the strips as a whole, which is secured to the window frame 10, by means of the parting-stop 11, which is inserted in a vertically extended mortise 16, as is clearly shown in Fig. 1, of the drawing.

Each of the weather strips 15, consists of a strip of metal possessing some resiliency and formed angular-ly in cross section, that is to say, is provided with two flanges 17, and 18, the former of which will be termed the mortise flange, and the latter the guide way flange. As shown in Figs. 1, and 2, the mortise flange 17, is extended into the mortise 16, at one of the sides thereof, and is held in place by the parting-stop 11, in such a manner that the guide way flange 18, will lie against the inner surface of one of the guide ways of the upright 10, of the window frame. The mortise 16, is preferably formed at the inner edge of each of its sides with an enlargement 19, to receive a deflected portion 20, on the free edge of the flange 17, thus providing means for more securely holding the strip in position when the parting-stop 11, is inserted in its mortise. As is clearly shown in Fig. 2, the guide way fiange 18, is provided with a leaf 21, bent approximately back upon the fiange 18, which leaf has an extension 22, integral therewith, and interposed between the flange 18, and leaf 21, and normally at angles thereto. As the strip is composed of resilie'nt inaterial, it is apparent that the parts before the sash frames are placed in position, in the window frame, will assume the positions shown in Fig. 2, of the drawing, but when pressed by the side rails ofthe sashes, the parts will lie in parallelism or substantially so, one with the other, as is shown in Fig. 1, of the drawing.

By constructing the weather strip as above described, it is apparent that one may be placed on each side of the inortise 16, and that the parting-stop 11, will firmly hold them in position without the use of spikes or other securing devices, and that the resiliency of the material will cause the flanges 18, and leaves 21, to rest closely against the surface of the guide Ways in the uprights 10, and against the adjacent surface of the sash stiles 14, respectively, and in such a manner as to absolutely exclude the passage of air, and to prevent the sashes rattling.

In Figs. 3, and 1, of the drawing, is shown a modification in the construction of the weather strips which is more especially adapted to be applied at the bottom and top of the window frame and it consists in employing a strip which is indicated as a whole, by the reference character 15a, which consists of a strip or piece of metal possessing some resiliency and formed angular in cross section, that is to say, with a narrow flange 17, to fit under the inner edge of the stool 23, ofthe window frame, and with a wider flange 1S, to lie vertically against the inner surface of said stool. In this modified construction the flange 17, corresponds with the mortise flange 17, of the first described construction, except that it is much narrower, and is not provided with a deflected portion Q0, while the flange 18a, corresponds with the flange 18, of the first described construction, and like the saine is provided with a leaf 21a, having an extension 22, integral therewith, and interposed between the flange 18a, and lead 21a, and angular thereto. Secured to the upper surface of the window sill 24, near the inner portion of the stool 23, is a metal strip or base piece 25, which has an upturned flange 26, interposed between the flange 18a, the leaf 21a, and the free edge of the extension 22,

thereof, which will give additional strength or rigidity to the strip 15a, as is apparent.

In Figs. 5, and 6, is shown still another modification in the construction of the weather strip, which is designed to be applied to either the uprights of the window frame and side stiles of the window sashes, 01 to the sill, which consists of a strip of metal designated as a whole, by the reference character 15b, which is bent angularly in cross section, that is to say, to form a flange 17D, to rest against and be secured to the inner portion of one of the sides of the parting-stop 11, and the flange 18, to lie against the surface of one of the guide ways of the upright 10, of the window frame. rlhe flange 18D, is provided with a leaf 2lb, which is integral therewith, and bent approximately back upon the same, yet normally has its free edge at a slight distance therefrom, thus affording a resilient leaf 2lb, to rest against the outer surface of one of the side rails 141, of the window sash. Secured to the parting-stop of the window frame, is a strip of metal 25a, which is provided with a flange 26a, at an angle thereto, and is interposed between the leaf 2lb, and the flange 1S", which will strengthen the strip 15, and firmly hold it in place.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent is- The combination with a window-frame having the usual parting stops, of a piece of metal having a flange secured longitudinally in the groove in which the parting stop is fitted and provided with another flange at an angle to the first-named flange and lying longitudinally against the inner surface of the guide way for the window sash, the last-named flange having a leaf integral therewith and extended approximately back thereon toward the parting stop, and an extension on said leaf interposed between the leaf and the secondnamed flange and normally at an angle to the same.
