The present invention relates toa weatherstrip and has particular reference to that type of window weather-strip which is interposed between the sliding sashes in the ol sition generally occupied by the parting bead or strip.

One of the particular ob'ects. of the invention is to provide a weat er-strip of this type characterized b an improved manner of fastening the weat er-strip to the window frame. The present mode of fastening greatly simplifies the mounting of the weather-strip, and avoids the likelihood of deforming the weather-strip in the attaching thereof to the window frame,

Another objet t of the invention is to provide a weather-strip in which the sealing surfaces will have an increased resiliency or spring for maintaining firm sealing contact with the window, for adaptin the strip to different sizes of windows, an for compensating for wear between the sealing suraces.

Another object of the-invention is to provide a weather-strip which will afford the usual line of sealing contact along the side of the sash, and, in addition thereto, will afford a closure or line of sealing along the edge of the sash. This sealing contact at the side and at the edge of the sash greatly increases the effectiveness of the weatherstrip for excluding the weather. The resiliency of the weather-strip along the side line of sealing contact and along the edge line of sealing contact also effectively prevents rattling of the window sash in any plane.

In the following description I have described my invention as embodied in different forms of weather-strip designed primarily for sliding sash windows. In view of the fact, however, that certain of the essential features of my invention have wider application to weather-strip and closure strip than to these particular windows, I have drawn some of t e appended claims to cover a more general application of these essential features.

In the drawing illustrating the preferred window embodiments:

Fig. 1 is a fragmentary horizontal sectional view throu h the conventional window; having two s iding sashes.

Fig. 2 is a vertical sectional view through the same, taken approximately on the plane of the line 2-.--2 of Fig. 1.

vFig. 3 is a sectional view on a larger scale of a modified form of window strip,

and

4, 5 and 6 are similar views illustrating other modifications of my invention.

Referrin to Fig. 1, the side rails of a typical sli ing sash window are indicated at 11-41, and the two sliding sashes are indicated at 1212'. The two sashes 12- 12'v are usually guided in vertical guide channels 1-1 which are formed ontheir outer sides by guide strips 15 secured to the window frame. two sashes are held separated for sliding movement in separate parallel frames by a parting head or strip which is secured to the rails '11 of the window frame and which projects slightly between the opposing sides of the sashes. This parting bead or strip is not shown, it being supplanted by the In the usual construction the present weather-strip. Generally, this part-- mg head or strip is set into a channel shaped groove or recess 17 formed in the side rails of the window frame, this groove and its associated parting bead usually being of a width substantially equal to the width of the space 18 between the two sashes. In adapting my improved weather-stri to this conventional window construction utilize the groove -17 for seating a part of the weather-strip. v

The present weather-strip is constructed entirely of a sin lestri of sheet metal, devoidof any rubTmr surihces or other material likely to wear or deteriorate. 'In the particular embodiment shown in Fig. 1 this strip of sheet metal is formed with a channel shaped portion 21 of theflproper size to fit into the groove 17. Extending laterally from one side of this channel shaped portion is an attaching flange 22 which is adapted to overlie and bear against the surface of the frame rail 11 along the side of the groove 17. This attaching flange has a plurality of holes 23 therein for receiving the shanks of tacks or nails 24:.

From this attaching flange the metalis then doubled back through a curved fold ..to form a second outer flan e 25, which outer flange is spaced slightly From the inner 6 attaching flange 22. This outer flan e also has a luralit-y of holes 26 therein, a 1 ed with t e holes 23 in the inner attac flange, the holes 26 being of suflicient size, however, to pass the heads of either the tasks 10 or nails 24. After the channel shaped portion 21 has been seated in the groove 17, these tacks or nails are centered in the holes 23 and are driven with a punch or other suitable instrument to prevent deforming 1 the outer flange 25,- engagement ofthe heads of these tacks or .nails with the inner flange 22 securely fastening the strip to the win dow frame; the engagement of the channel shaped portion 21 in the groove 17 assists these nails in holding the strip against 25, subpermitting'it to sprin towards and away om the flange 22, and this resiliency tends 3 to press this flange 25 against thedge of.

the sash, thereby affording a line of sealing contact with the edge of the sash, or substantially closing the space which usually exists between the edge of thesash and the window frame. The side sealing flange 28 similarly has considerable resiliency tendin to maintain it in firm sealing contact wit the side of the window sash, It will be noted hat the resiliency of this side sealing flange 4 '28 extends through the bowed formation thereof and back through theedge sealing flange 25 to the point of attachment of the fastening tacks with the attaching flan e 22, whereby this side sealing flange has a ditional resiliency tending to prevent it from assuming an set curvature or position out of contact wit the sash. The resiliency inherent in the edge sealing flange 25 and in the side sealing flange 28 takes up wear, adapts the weather-strip to windows of different dimensions, and avoids all possibility of the sashes sticking. Also, by fastening the weather-strip to the window frame through the laterally extending attaching flange 22, the difli'culty of inserting tacks in the depressed channel portion 21 is-avoided, and the side sealing flanges 28-28" can be made with relatively large beaded edges 29 which substantiall close the space between these side sealing an'ges.

Where the weather-strip is only provided with an attaching flange 22 on'one side, as shown in Fig. 1, I prefer to use separate strips for the 11 per and lower halves of the window and to nvert or reverse these strips as shown in Fig. 2. That is to say, when the weather-strips are thus arranged the edge sealing flange 25 for the u per section of weather-strip will engage behind the edge of the u per window sash when this sash 1s in close position and the edge sealing flan e for the lower section of weather-strip Wlll engage behind the ed of the lower sash when this sash is in c osed position. With this arrangement of the two sections of weather-strip the beaded edges 29 of the side sealing flanges 28 will extend in alignment and form a continuousparting bead extending from top to bottom of the window frame. Irrespective of what position the sashes 12 and 12 are moved to, they will never pass out of engagement with their res ective edge sealin anges 25. In the modi cation shown in 1 3 the weather-strip is formed with a flat portion 32 devoid of any channel depression. 21. This type i of weather-strip maybe employed where the window frame has no groove 17 for the parting bead; or'it may even be employed where the. window frame has such ves. In this form both sides of the weat er-strip may be provided with attaching flanges 22 and with edge sealing flanges 25. Where edge sealing flanges are provided along. op osite sides ofthe strip a single continuous ength of stri may be extended from top to bottom of the window frame.

In the modification shown in Fig. 4 the beaded edge of one of the side sealing flanges 28 is formed :with. a laterally extendin flange 33, which contacts with the beade edge of the opposite sealin flange 'com gletely to close the space between these anges.

In the modification illustrated in Fight the side sealing flan s 28-28 are provided with straight overapping flanges 34-34 which completel close the space between these flanges. terminate .suflicie'ntly short of the outer sides hese closed flanges 34--34 of the side sealing flanges so as not to restrict the lateral, resiliency of these sealing flan es. 1 Fig. 6 illustrates this same arrangement of over-lappin closure flanges in a weather strip having ge sealing flanges 25 on both sides thereof.
