WEATHER STRIP Filed Sept. 7, 1953 4 Sheets-Sheet 4 Tic-iidbmmq/s FEEL Patented Sept. 11, 1934 NITED STATES PATENT FFIE 20 Claims.

This invention appertains to concealed weatherstrip constructions primarily adapted for use in door and casement window installations wherein it is desired to effectively seal a swingable closure member in its cooperating frame.

In the usual and known types of Weatherstrip constructions, considerable difficulty is en countered in maintaining a good seal after a short time of use following the installation of the Weatherstrip, even though the seal may be adequate at first. Shrinkage and warping of the sashes and/or frames tends to misalign the weatherstrips or otherwise subjects them to strains so that the sealing effect is materially reduced if not wholly destroyed. Under some conditions the misalignment or distortion of the weatherstrips becomes so great that the door or window cannot be completely closed or may be closed or opened only with great difficulty owing to the excessive friction or sticking or jamming of the parts. It not infrequently occurs that the shrinkage above referred to, or the operation of the members when the weatherstrips are for some reason distorted or misaligned, causes the weather strips to pull loose on their nailings.

In addition to the foregoing, the construction self-adjusting to automatically accommodate shrinkage and warping conditions of the members with which the Weatherstrip is associated; and further, which enhances the smoothness and case of action of the sash in opening and closing movements.

To the end of reducing friction and the possibility of sticking to a minimum, I have provided a Weatherstrip of such configuration that it tends to move the sash toward open position as soon as the lock or latch devices which secure the sash in closed position in its frame, are released,

thereby actually assisting in the opening movement of the sash.

The invention has for a further object the provision of a Weatherstrip embodying a sealing strip or flange arranged for effecting a weatherproof seal through edgewise contact of the free edge of the flange, the flange being suitably 5 carried on the frame so as to afiord free lateralmovement of the flange, enabling an automatic positioning of the same when the sash is closed, and the free edge of the flange being normally out of sealing contact as when the sash is open, but the flange being swingable about an axis extending longitudinally with respect thereto so as to bring said free edge into such sealing contact when the sash is closed.

A still further object of the invention is to provide a Weatherstrip in the form of one or more folds of resilient material, one fold being provided with an outwardly diverging sealing flange, and this fold being mountable in inverted relation to the member to which the Weatherstrip is applied so that the free edge of the sealing flange constitutes the sealing edge.

Another object of the invention is to provide a weatherstripwhich is simple and easy to install and which minimizes likelihood of becoming damaged or permanently distorted when exposed to accidental impacts or pressure of extraneous bodies as when the door or window is left in open position for substantial periods of time.

Other and further objects and advantages of the invention will become apparent from the following description and the novel features thereof defined by the appended claims.

Figure 19 is a view similar to Figure 2, but showing a double casement window or door construction, the weatherstrips for the hinge sides being omitted.

Figure 20 is an enlarged fragmentary detail view of the' meeting stiles of the construction --of Figure 19, showing the Weatherstrip arrange: ment as applied to such meeting stiles.

Figure 21 is a view taken approximately on the line 2l2l of Figure 20in the direction of the arrows. I

Figure 22 is a fragmentary perpective view of an escutcheon plate for the double casement constructions of Figures .19 and 20.

It is to be understood that While the invention is particularly described and shown in its appli-- cation to casement window constructions, it is not confined thereto since itis equally applicable to doors or any closure construction embodying a member swingably mounted for cooperation with a frame or other member with which a sealing relation is to be established. The axis of swing may obviously be either vertical, horizontal, or otherwise. Noris the invention confined to use with swingable closures since under some conditionsand in certain forms shown and described, it may be applied to the usual sliding type of windows or double-hung windows, in which event the novel construction of my strip serves excellently to prevent rattling of the window.

Like reference characters designate corresponding parts in the several figures of the drawings. Referring first to Figures 1 to 4 and 18, there is shown a window frame generally denoted by the reference character 1, embodying a jamb 2 and a stop 3 with which the window sash, gener ally designated 4, is adapted to cooperate when in closed position. Suitable hinges 5 are ernployed to swingably mount the sash 4 in the frame for opening preferably in an inward direc-' tion. It will be understood that'the sash and frame is of the usual construction.

The free edge of the sash, that is the lock side, designated 6, is rabbeted at 7 to receive one of a pair of interlocking weatherstrips WhiCh'fiJlB to be arranged to seal the free edge of the sash rel atively to the frame. In one form, this member which is to be mounted in the rabbeted portion comprises a reversely bent or folded strip 8 affording a first fold or tongue 9, and a second fold 10 affording a substantially U-shaped channel 10. Attaching flanges 11 and 12 are provided by means of which thestrip may be nailed or otherwise secured in position.

The member which is. to cooperate with the reversely bent member 8 is applied to thejamb 2, and in one form comprises a reversely bent or folded strip generally designated 13, providing a, first fold 14 affording a substantially U-shaped channel or groove 14 for receiving the tongue 9 of member 8, and a second fold 15 having a sealing flange 15 which is angularly offset in an outwardly diverging direction for purposes to be hereinafter described. A laterally offset attaching flange. 16 is-provided for the member 13 by meansof which the member maybe secured to the jamb by nails or in any other suitable manner. 'It'Will be observed that in applying the strip 13 to the frame, the same is positioned so that the first fold 14 is located against or in close proximity to the inner surface 1'7 of the stop 3. Thefree edge ofthe outwardly diverging sealing flange 15 normally terminates in slightly spac ed relation to the surface 1'? when the mem ber 13 is applied to the frame in the manner described. In other words, the sealing flange 15 does not project as far forwardly as does the bend forming-the channel 14 so that when the member 13 is applied to the frame, the free edge of the sealing flange will not engage the stop.

In closing the window to which has-been applied the member 8, the tongueQ will be pressed into the channelli of member 13, and the groove or channel 10 of member 8 receives and encompasses ,the. second fold of member l3 including the sealing flange 15. As this takes place, the folds and sealing flange 15 may move in either direction laterally, owing to the lateral offsetting of the attaching flange 16, depending upon which sides of the folds interengage. first, thereby accommodating and automatically adjusting the parts regardless of misalignments or deformations due to shinkage and warpage of the sash or frame. As the sash reaches its final closed posithe latter occurring at the line of contact be-v tween the sealing flange and the cooperating sealing member 8 carried by the sash. Thus, air, rain, snow, dust, :and other foreign matter is effectively excluded and prevented from entering between the window frame and the sash.

The member 8 may be formed of any suitable material which is relatively stiff and substantially rigid so that it will hold its shape. The cooperating member l3.is preferably formed of resilient material, such as spring bronze of the type customarily employed in metal weatherstripping practice. It is this latter member which permits of the automatic adjustment of the interlocking strips, the fold carrying the seal ing. flange 15, being yielclably movable laterally.

As has been mentioned above, the free edge 19 of the sealing flange 1-5 is normally spaced from the surface 17 of the stop 3, that is, when the sash is opened so as to disengage member 8 from member 13 (shown best in Figure 18) In bringing this free edge into sealing contact with the surface 17, the sealing flange 15 swings on an axis extending longitudinallyrelatively to the strip, folds l5 and 14 resiliently resisting the movement of the flangeto bring the free edge19 into sealing contact with the surface 17. -.As.shown, the seale mg flange lSbegins to diverge outwardly at 20, which is preferably slightly forward of the base of the second fold of member 13, thereby giving to. the sealing flange a somewhat greater angle of divergence to insure positive sealing contact of the free edge 19 under the influence of the portion of member 8 contacting with the flange when the window is closed. This angle of offset or divergence is such that it materially assists in opening the window. As soon as the usual lock or latch (not shown) for the windowis released,.the resisting pressure of the sealing flange tends to start the motion of the window in an outward direction; that is, in an opening direction, so that the member 8 starts to disengage from member 13. Conversely, inclosing the window, the last part of the closing movement may be effected by the window lock or latch which will positivelyforce or cam the member 8 into engagement with member 13 and bring about the positive sealing con- From the foregoing it will be clear that the es-' sential feature of member 13 is a fold 15' which is relatively inverted with respect to one surface with which it is to cooperate for sealing purposes, the fold including an outwardly diverging or angu ...y inclined sealing flange, the free edge of which is normally spaced from said surface but 1 capable of being brought to sealing contact there-- with by the application of pressure on said sealing flang The use of an additional fold. laterally spaced and reversely extending with respect to the inverted fold, while not being necessary, gives greater flexibility of movement and eiflciency in action. 1

This arrangement also minimizes likelihood of distortion iamage of the strip 13 by accidental impacts or biows to which it might be subjected when the window is in an open position, so as to expose this member. The reversely extending folds are capable of withstanding considerable pressures without producing permanent distor-, tion.

To minimize the likelihood of sticking or looking of the free edge 19 of the sealing flange 15 t the same is pressed into contact with the surface 17, the free edge may be ,rebent onitselfv as at 21. This rebending also produces a stiffening of the sealing edge so as to insure good seal-.- ing contact. Similarly, the free edge of attaching flange 16 may be rebent on itself as at 22 to stiffen this edge and to produce an effective sealing contact with the jamb when the flange is attached thereto. In using this construction, fewer nails or other securing devices will be necessary in applying the member 13 to'the jamb so that the attaching flange will be maintained perfectly flat and in good sealing contact with the jamb.

The construction of members 8 and 13, as above described, may be followed for sealing the upper edge or head of the window as shown clearly in Figure 1. 1

Referring now to the hinge side of the window as shown in Figures 2, 3, and 5, the sash may be rabbeted at 23 in a manner similar to the rabbet '7 on the free edge, and the sealing member 8 applied thereto, as hereinabove described. The 00- operating sealing member embodies aninverted' fold 15 including the outwardly diverging sealing I flange 15, constructed entirely similar to the outer ing solely the first portion of sealing member 13 for the lock side of the'window, except that fold 14' is omitted. Attaching flange 24 is provided for fold 15' so as to extendlaterally therefrom for application to the jamb of the frame. For this hinge side installation, the free edge 19 of the sealing flange 15 is arranged forsealing contact with the jamb instead'of the stop, the free edge howeverbeing normally out ofcontact with the jamb when the window is in open position. As the window is closed, fold 15 is automatically guided into the channel formed by fold 10" of member 8, and tongue 9 ofmember 3 engages sealing flange 15 so as to press the free edge 19 of flange 15 into sealing contact with the jamb during the final closing movement of the window, the operation being similar to that described with relation to the engagement and disengagement of the sealing members on the lock and head sides of the window. i

i The sealing member which is applied to. the sash at the loci: and head sides, may. have other forms than that of member 8, hereinbefore described As shown in Figure 6, the construction is the same except that the attaching flange ll. of member 8 in Figures 1 to and 18 is omitted, the application of the sealing member to the sash being made entirely by the attaching flange 12. The cooperating member shown in Figure 6 is the same as member 13 described in the preceding figures. Figures Sand 15 show a further modified form of member 8 which may be employed onthe' loci: and head sides of the sash, this modification omitting the second fold 16' of member 8, hereinbefore desc"'bed, and embody fold or tongue .9 and attaching flange 12, cooperating ser 13 being th same. A'still further modification of member Sis shown in Figures 11 and 16 in which it has the form of, a lapped strip providing a tongue 9', the free sides'of the lap forming a double attaching flange 12'. Member 15 remains the same in this construction and cooperates with tongue 9' in a manher which wlll be clearly apparent from the drawings. In the modifications of Figures 8 and 11, the rabbeted corner of the as at 25, is broughtto' bear on the sealing flange 15 to effect sealing contactof the free edge 19 of the sealing flange withsurface 17 of stop 3.

Figure 7 shows a modified construction for the hinge side of the window wherein a single weatherr'trip sealing element is employed, element having the same form as that shown on the hinge side inFigures 2, 3 and 5. In such a modified installation the inverted fold is reversed with respect to the position shown in Figures 2, 3 and 5 so that the'attaching flange 24 extends in the opposite direction for insertion into a lrerf 26 cut in the corner of the frame formed by the stop 3 and jamb 2. The hinge side of the sash is rabbeted at'23 to receive the inverted iold and cooperates therewith to effect a seal a manner which will be fully apparent from the drawings taken'in conjunction with the description of the operation of the Various modifications hereinbefore described. In this construction of Figure 7, the sash need not be provided with any interlocking sealing element since the rabbet 23' serves as the means for producing the sealing action.

Figures 9 and 19 show constructions similar to the hinge side of Figures 2, 3 and 5 except that the sealing elements applied to the sash are similar to the elements shown on the lock side in Figures 8 and 11, respectively.

. Referringnow to Figures 19 to 22, there is shown an arrangement suitable for application to double easements, the meeting stiles of the casements 2'? and 28 being provided with the sealing elements in a manner similar to the previously described installations, for single easements. One stile is suitably rabbeted as at 29 for the application thereto of a member conforming to member 8 of Figures 1 to 4 and 18. The cooperating member applied to stile 27 is similar to member 13 except that the attaching flange is bent over as at 30 for the attachment of the member to the stile. An escutcheon 31 is secured to one of the stiles as by screws 32 and serves to provide a surface against which the free edge of the sealing flange of member 13 is adapted to be brought into sealing contact so as to exclude water, dust, etc.

The escutcheon is shown in greater detail in Figures 21 and 22.

In Figure 17 there is shown a sealing member conforming to member 13 of Figures 1 to 4 and 18, the end of member 13 being cut to provide upwardly bent flaps or extensions 33 and 34. This Figure has particular reference to the formation of the lower ends of members 13 when applied to the vertical sides of the window frame. lower side of the lower edge of the window in practice would generally have associated there with a self-draining type of Weatherstrip of conventional form, such a Weatherstrip being shown.

in Figure 1. By suitably forming the lower ends of the weatherstrips applied to the hinge and lock sides of the window, as shown in Figure 17, water which may collect within the folds of member 13 will be deflected outwardly or toward the weather side of the window between the bottom of the sash and the conventional self-draining channel.

The operation of my improved Weatherstrip should be apparent from the foregoing description taken in conjunction with the illustrations of the drawings, and it will be apparent that there is provided a Weatherstrip which is simple in construction but positive in action, eliminating many of the common difficulties encountered in the usual constructions.

While the specific details of construction have been herein shown and described, it is to be understood that the invention is not to be confined thereto since changes and alterations may be made without depmting from the spirit thereof as defined by the appended claims.
