- the weather stripping of my invention is preferably formed from a continuousflat strip of sheet high tension commercial spring bronze of .005 inch thickness, which is rolled to the form shown.
- the weather strippingjd in cross section comprises two- U-shaped portions 8 l and i2 disposed at right angles to each other and arranged somewhat in the form of a figure 5.
- the width of each U-shaped portion is substantially equal to its height. Attention is directed to the relative positions of the U-shaped portions Hand E2.
- the U-shaped portion 2 is spaced from the portion l l and so disposed that its night is opposite and faces one leg l to of the 9 U-shaped portion H.
- An extension E3 of the leg liia of the U-shapedportion 12 extends between and interconnects the two U-shaped portions ii and i2.
- the far leg lib of the U-shaped'portion n i l--far in relation to the interconnecting web lit carries at its extremity an outwardly directed flange He.
- the far leg l2b of the U- sha ped portion 52 carriesan outwardly directed flange E20.
- the connecting web i3 is a co-planar extension of the near leg i211 of the U-shaped portion 52. If an imaginary line such as M of Fig.
- each of the leg portions of the Us is reinforced or stiffened adjacent its edge, thereby giving not only the weather stripping as a whole but each component part thereof a stiffening.
- the U-shaped portions H and i 2 reinforce each other as to the component parts.
- the flange lid is stifiened at one edge by the interconnecting web 53 and at the other edge by the arcuate portion of the U.
- the leg lib is reinforced at one edge by the arcuate portion and at its other edge by the flange Ho.
- the leg I2?) is stiffened at one edge by the flange Ho and at its other edge by the arcuate curve of the U-shaped portion E2.
- the leg I20 is stiffened at one edge by the curve of the U-shaped portion l2 and at its other edge, by extension tlnough the web [3, by the leg Ha. In this manner I avoid the objec tion so often encountered in other types of weather stripping of the thin sheet metal portions which are relied upon to effect the seal becoming wavy due to lack of stiffening, and by the waviness, permitting the leakage of air.
- the casement sash comprises the usual top and bottom rails 95 and E and hinge and latch stiles H and E3.
- the frame comprises the head I9, stool 2i ⁇ , sill 2! and jambs 22.
- the head, stool and jambs are shouldered as at 23 to provide an abutment for the outside face of the sash.
- the sash is mounted on hinges whose pintles 24 are at the inside face of the sash.
- the opposite stile l8 carries a latch Edi-or preferably two latches, one near the top and the other near the bottom.
- the latch here shown is of the rotating type which engages the cam surface 25' of a cooperating latch piece 25 on the frame, in such manner that the sash is cammed tightly shut.
- a groove 26 is run along the top edge and the two lateral edges of the sash spaced inwardly somewhat from the outer face of the sash.
- a length of my weather stripping equal to the height of the sash, is mounted on the edge of the sash. This is done by inserting the U- shaped portion it into the groove 25 and securing it there by nails 2'! at intervals through the bottom of the U-shaped portion.
- a shallow depression 28 is formed for the reception of the flange N0 of the weather stripping, and if desired and preferably, the cut is extended in width to include that portion of the edge of the sash between the groove 25 and its outer face, whereby the web I3 and the flange He may lie in the same plane rather than being slightly offset.
- the distance by which the groove 26 is set back from the outside face of the sash is such as to leave an intervening portion of the edge of the sash equal in transverse width to the distance between the U-shaped portions II and I2 of the weather stripping, which is the width of the interconnecting web I3.
- the flange I 20 normally rests against the outside face of the sash.
- the groove 26 is of slightly less Width than the normal width of the U-shaped portion H so as to insure a tight fit of the U-shaped portion H in the groove 26 when the U-shaped portion H is secured in place by the nails 21.
- a groove 29 in form similar to the groove 26 is provided in the shoulder 23 of the jamb 22, one wall of the groove being a continuation of the sash opening 39.
- the groove 29 is also of slightly less width than the portion i2.
- the shoulder 23 preferably has a shallow depressed seat 23 formed therein for the reception of the flange 120, thereby enabling the remainder of the shoulder 23 to contact and form a tight abutment for the outside face of the sash.
- Fig. 3 which shows the position of the parts before the final closing movement of the door afforded by the camming action of the latch
- the surface of the sash opening is offset slightly from the adjacent lateral wall of the groove 29.
- the lock edge of the sash is slightly beveled.
- the clearance and bevel between the surface 36 and the edge of the sash, together with the resiliency of the U-shaped portion 12, permit the easy opening and closing of the sash between the open position and that of Fig. 3.
- Fig. 3 shows the position of the parts before the final closing movement of the door afforded by the camming action of the latch
- the leg 12a of the weather stripping is normally spaced a slight distance from the contact with the adjacent wall of the groove 29.
- the leg lZb' normally tends to overlap the opposite wall of the groove 29.
- the arrangement and operation of the weather stripping is substantially the same for the top edge of the sash.
- the clearance between the sash and frame is not made necessary by the slight throw occasioned by the position of the hinge pintle, but a similar clearance is nevertheless of advantage to prevent binding or sticking of the sash in the frame, especially such as might develop from a slight sag of the hinges.
- channel 34- is formed in the upper V liquely disposed atsubstantially the same angle as the oblique ducts 35 so that if they should become clogged, they may readily'be cleaned by r p a straight wire or equivalent instrument from. the inside of the house.
- the sloping wall of the channel 34 also facilitates brushing dirt out of the channel.
- the closing movement of the sash relative to the frame is not toward the shoulder 23 but substantially parallel with itand toward the surface 30 of the sashlopening.
- Becaus'e the groove 26 is' of slightly less width than the normal width of the U-shaped'po-rtion II, when the stripping'at the several corners of the sash, so as to prevent leakageof air at the corners.”
- the bottom weather stripping and the sash .siderweather stripping form a'corner, as illustrated in Fig. 5,
- the bottom edge of the sashedge weather-stripping extends to the top edgeof the face of the stool above the shoulder 33.
- The-bottom weather stripping simply extends to and terminates in the plane of the latch edge of the sash.
- the space designated by; 36 in Fig. is filled by the portion of the stool 31 of Fig. 4 which also seals the bottom end of the edge weather strip.- ping. Fig. 6.
- the aligned ends of the weather stripping may be mitered somewhat as in Fig. '7 with this diiference, that one is carried by the frame and the other by the sash whereby they come into miter corner relation only when the sash is closed.
- the lower sash 48 is mounted in the frame between the inside stop 44 and the parting stop 46, while theouter or upper sash'is mounted in the frame between the parting stop 46 and the blind stop 45. i
- the sash are free to reciprocate vertically in the usual manner, being balanced by the sash weights 50 and sash cords 5
- my weather strippingcan be-and in fact preferably is, as
- each sash is provided with a groove 54 spaced inwardly from the face of the sash by the width of the web ⁇ 3.
- the U-shaped portion H of the weather stripping enters the groove 54.
- the U-shaped portion l2 enters a groove 55 out into the face of the blind stop 54 which contactsthe face of the sash.
- the pulley frame 53 is preferably set, transversely of the width of the side jamb, at such a position thatitsprotruding hood portion is'contacted by the adjacent edge of the flange llc. l
- the weather stripping may if desired be nailed or otherwise fixed to the side lamb 1 or to the blind stop, it is not necessary that this be done. Onthe contrary, I find it sash tends to position it. To remove the weather stripping, the sash may be moved to its lowermost position, and its unfixedupper end of the strip may be pulled out and the'entire strip drawn upwardly withdrawing it from its grooves in the sash and the blind stop.
- the flexibility of the weather stripping permits this.
- the fact that the side weather stripping is not fixed to the frame-or sash greatly simplifies the, operation of removing the sash where the outside stop would have to be removed.-
- the grooves are of slightly less width than the normal width of the U-shaped portion of the weather stripping which they receive. Conse-. quently the weather stripping exerts a spreading action and results in a two-point seal at any transverse section of the groove. Because of this rela-1 tion a slight transverse movement of the sash, while it might similarly transversely move a floatingweather strip, does not substantially affect the seal of the weather stripping with the groove and the stop.
- the floating weather stripping and the compressed fit of the U-shaped portions of the weather stripping in the grooves make possible a relatively loose fit of the reciprocating sash between the stops without impairing the quality of the seal afforded by the weather stripping, Ample clearance for the sash may be provided to forestall its sticking without impairing the weather tightness of the window as effected bythe weather stripping.
- the weather stripping also acts with a mild braking effect on the sash as it is reciprocated, thus avoidingthe falling of the sash if the weights are not adequate. This braking effect is the result of the friction developed by the slight spreading action of the U-shaped portions ll of the weather stripping which work in the grooves 54 of the sash.
- a groove 5'! similar to the grooves 54 is formed in the upper edge of the upper sash.
- the groove 51 receives the U-shaped portion H of the top weather strip,'as shown at the top of Fig. 9.
- the U-shaped portionlZ of the weather stripping is received in a groove 58 in the top blind stop 45.
- the top weather stripping may be held in place by nails 59 driven through the web portion l3 into the head jamb 4!. Otherwise there would be nothing to hold the weather stripping in position when the upper sash was down except the friction of the U-shaped portion which enters the groove 58. Nailing the top weather stripping to the head jamb or the top blind stop .does not interfere with removal of the sash.
- the U-shapedportion E2 of the lower weather strip is received in a groove 69 formed jointly in the stool and sill.
- the weather strip is prefer ably nailed to the frame.
- the U-shaped portion l l of theweather strip enters a groove 8! in the bottom of the sash which is similar to the side grooves 56.
- the upper part of the U-shaped portion ii is rounded so that it tends by a camming action ,to pull the lower end of the sash into proper position if the sash be loose in the frame. Failing this, the inherent flexibility of the weather stripping would permit the necessary slight deformation in the cross section of the weather stripping toinsure its entering the groove and making a weather tight seal against the walls thereof. The same action is true of the top weather strip.
- the shallow depression cut adjoining the groove, for the reception of the flange l 20 of the strip, is somewhat deeper in the instance of the top and bottom of the double hung sash than in the instance of the casement sash. This is to eliminate danger of the flange l2c being caught by the corner of the double hung sash as it moves past the flange l2c. Also, as will be seen froma close inspection of Fig. 1, the flange E20 is at a slightly acute angle to the leg IN). This tends to-draw the raw'edge of the flange I20 further into its depression.
- the top rail of the sash 48 has a down-facing shoulder 62 which, when the two sashes are closed, overlies and rests against an up-facing shoulder 63 on the bottom rail of the upper sash 49.
- a groove 64 is formed on the outer face of the upper rail of the sash as and below the shoulder 63. In this groove 5 is secured, as by nails, the U-shaped portion 1! I of-the inter-sash weather strip. The strip is thus carried by the sash 49 with its U-shaped portion l2 extending upwardly above the shoulder 63.
- the u-shaped portion I2 is received by a groove 65 formed in the shoulder 62 cf the lower sash 48.
- The'weather strips for the sides of the lower sash and for the bottom of the lower sash are co-planar; therefore their corners may be mitered at the lower ends of the lateral strips.
- the ends of-the inter-sash weather strip come against the inside face of the'lateral parting stops 66.
- the grooves may initially out to the most advantageous depth. However if the sash are made slightly oversize to be fitted to the frame by the carpenter on the job the grooves 54, 57, and El may be made as much deeper as the sash is made oversize. An excessive depth to these grooves will not impair the functioning of my weather stripping.
- a weather stripping comprising a strip of sheet metal of a cross section arranged ina 5- shape comprising afirst open U-shaped portion, asecond open U-shaped portion of a size of the order of the first U-shaped portion, the second U-shaped portion being disposed with its bight facing the adjacent leg of the first U -shaped portion, one leg of the secondwshaped portion being extended as a web co-planar and connecting with the end of said adjacentle'g of the first U-shaped portion, the web being of such length that the other leg of the'second U-shaped por.

' .zo oin s; c1.'20 t9)v 7 My invention relates to weather stripping and particularly to the metallic type of weather stripping to be used with easerh ent windows, doors and double hung windows. g among the objects of my invention are these: A single standard form of weather stripping adaptable to both casement and double hung windows; a weather stripping which can be applied to the edge face of a casement or door and operate in conjunction with agroove in the frame facing the inner faceof the casement or door wherethe groove canbe relatively wide without requiring a substantial'space ior the" weather stripping beyond the edge of the casementor door; a tight fitting weather stripping applicable to the edge of a door or casement remoteirom the hinge edge but still permitting clearance in swinging necessitated by the hinge pintle being on the side of the easement or door opposite the side on which the weather stripping seals; a single standard form of weather stripping which is adaptable to the difierent kinds of relative movement at the hinge edge and the latch edge of a casement or door, that at the latch edge being transverse to the door and that at the hinge" edge being parallel with the door; provision. for sealing the door or window at the corners where the endsof the lengths of weather stripping corne to:
gether; and an improved drain for use Tin connection withweather stripping especially on inswinging easements to drain water backto the sill.
The foregoing, together with further objects, .featuresand advantages of my inventionare set forth in the following description of specific enibodirnents thereof which are illustrated in the accompanying drawings wherein:

Fig. '7 is a fragmentary detail perspective view of the inside faceof the upper latch side corner of the casement'sash showing the miter joint of the weather stripping at the corner;
Fig. 8 is a horizontal detail section through the meeting (or look edge) rails of a pair of casemerit sash."
Fig. 9 is a vertical transverse section through a double hung window and'its frame to which hasalso been applied the weather strip of Fig. 1;
and" i r Fig. 3.6 is a horizontal sectionthrough the jamb of the window of Fig. 8 and may be considered as taken on the line re it of Fig.9.
The weather stripping of my invention, best illustrated in Fig. i, is preferably formed from a continuousflat strip of sheet high tension commercial spring bronze of .005 inch thickness, which is rolled to the form shown. The weather strippingjd in cross section comprises two- U-shaped portions 8 l and i2 disposed at right angles to each other and arranged somewhat in the form of a figure 5. The width of each U-shaped portion is substantially equal to its height. Attention is directed to the relative positions of the U-shaped portions Hand E2. The U-shaped portion 2is spaced from the portion l l and so disposed that its night is opposite and faces one leg l to of the 9 U-shaped portion H. An extension E3 of the leg liia of the U-shapedportion 12 extends between and interconnects the two U-shaped portions ii and i2. The far leg lib of the U-shaped'portion n i l--far in relation to the interconnecting web litcarries at its extremity an outwardly directed flange He. Similarly the far leg l2b of the U- sha ped portion 52 carriesan outwardly directed flange E20. The connecting web i3 is a co-planar extension of the near leg i211 of the U-shaped portion 52. If an imaginary line such as M of Fig. 1' be drawn to define what would otherwise be the edge of the near leg 82a if it were of the same length as the far leg i2b, it will be seen that the space represented by' the connecting web it, by whichthe U -shaped portion l 2 is spaced from the u-shaped portion 1 l. is substantially thesame as the length or breadth of either of the U-shaped portions. Thus, ignoring the flanges Ho and its, the area of .the cross-section of my weather stripping can be considered as divided into equal thirds, each third being substantially square, onethird being occupied by the U-shaped portion 1 l, the second by the intervening space between the U shaped portions and including the web 3 and the third the U-shaped portion I2. I am mentioning this better to describe the form and proportion of my weather stripping as I prefer to make it, and is not to be construed as an essential limitation.
It is a feature of my weather stripping that each of the leg portions of the Us is reinforced or stiffened adjacent its edge, thereby giving not only the weather stripping as a whole but each component part thereof a stiffening. In general, the U-shaped portions H and i 2 reinforce each other as to the component parts. The flange lid is stifiened at one edge by the interconnecting web 53 and at the other edge by the arcuate portion of the U. The leg lib is reinforced at one edge by the arcuate portion and at its other edge by the flange Ho. The leg I2?) is stiffened at one edge by the flange Ho and at its other edge by the arcuate curve of the U-shaped portion E2. The leg I20: is stiffened at one edge by the curve of the U-shaped portion l2 and at its other edge, by extension tlnough the web [3, by the leg Ha. In this manner I avoid the objec tion so often encountered in other types of weather stripping of the thin sheet metal portions which are relied upon to effect the seal becoming wavy due to lack of stiffening, and by the waviness, permitting the leakage of air.
I shall first describe the application of my weather stripping to the instance of an inswinging wood casement window as illustrated in Figs. 2 to 7 inclusive. The application of my weather stripping to a door is so similar to the application to a casement window, that I believe it is unnecessary to illustrate the application to the door specifically. For the purpose of the description and claims of this application, the casement sash may be considereda door.
The casement sash comprises the usual top and bottom rails 95 and E and hinge and latch stiles H and E3. The frame comprises the head I9, stool 2i}, sill 2! and jambs 22. The head, stool and jambs are shouldered as at 23 to provide an abutment for the outside face of the sash. The sash is mounted on hinges whose pintles 24 are at the inside face of the sash. The opposite stile l8 carries a latch Edi-or preferably two latches, one near the top and the other near the bottom. The latch here shown is of the rotating type which engages the cam surface 25' of a cooperating latch piece 25 on the frame, in such manner that the sash is cammed tightly shut.
A groove 26 is run along the top edge and the two lateral edges of the sash spaced inwardly somewhat from the outer face of the sash. Referring to the left-hand portion of Fig. 2, which shows the groove 26 in the lateral latch edge of the sash, a length of my weather stripping, equal to the height of the sash, is mounted on the edge of the sash. This is done by inserting the U- shaped portion it into the groove 25 and securing it there by nails 2'! at intervals through the bottom of the U-shaped portion. In planing the edge of the sash, a shallow depression 28 is formed for the reception of the flange N0 of the weather stripping, and if desired and preferably, the cut is extended in width to include that portion of the edge of the sash between the groove 25 and its outer face, whereby the web I3 and the flange He may lie in the same plane rather than being slightly offset. The distance by which the groove 26 is set back from the outside face of the sash is such as to leave an intervening portion of the edge of the sash equal in transverse width to the distance between the U-shaped portions II and I2 of the weather stripping, which is the width of the interconnecting web I3. As a result, the flange I 20 normally rests against the outside face of the sash.
The groove 26 is of slightly less Width than the normal width of the U-shaped portion H so as to insure a tight fit of the U-shaped portion H in the groove 26 when the U-shaped portion H is secured in place by the nails 21. A groove 29 in form similar to the groove 26 is provided in the shoulder 23 of the jamb 22, one wall of the groove being a continuation of the sash opening 39. The groove 29 is also of slightly less width than the portion i2. The shoulder 23 preferably has a shallow depressed seat 23 formed therein for the reception of the flange 120, thereby enabling the remainder of the shoulder 23 to contact and form a tight abutment for the outside face of the sash.
Referring now to Fig. 3, which shows the position of the parts before the final closing movement of the door afforded by the camming action of the latch, the surface of the sash opening is offset slightly from the adjacent lateral wall of the groove 29. There is a suflicient clearance between this surface and the edge of the sash to permit the outswinging of the sash, the hinge pintle 24 being at the outer face of the sash. For the same reason the lock edge of the sash is slightly beveled. The clearance and bevel between the surface 36 and the edge of the sash, together with the resiliency of the U-shaped portion 12, permit the easy opening and closing of the sash between the open position and that of Fig. 3. As shown in Fig. 3, as the sash is cammed shut by the latch, the leg 12a of the weather stripping is normally spaced a slight distance from the contact with the adjacent wall of the groove 29. On the other hand, the leg lZb' normally tends to overlap the opposite wall of the groove 29. As the latch cams the door shut, the corner formed by the wall of the groove 29 and the shallow seat 29' contacts the curve of the U-shaped portion l2 near the leg H22), and cams the entire portion 92 toward the left, whereby it may enter the groove. In the final position, as shown in Fig. 2, this camming or shifting of the U-shaped portion E2 to the left has resulted in a pressure contact of the leg i211; against the adjacent wall of the groove 29, while there is a secondv pressure contact of the leg I2b against the opposite wall of the groove 29 adjacent the recessed shoulder seat 23. The two legs l2a and 12b are compressed together against their normal resiliency, whereby they maintain this double seal against the groove 29, and this double sealis maintained notwithstanding that the outer face of the sash may be warped somewhat out of a vertical plane.
The arrangement and operation of the weather stripping is substantially the same for the top edge of the sash. Referring to the top of Fig. 4, the clearance between the sash and frame is not made necessary by the slight throw occasioned by the position of the hinge pintle, but a similar clearance is nevertheless of advantage to prevent binding or sticking of the sash in the frame, especially such as might develop from a slight sag of the hinges.
Substantially the same application and arrangement of my weather stripping is also used at the bottom, as shown in Fig. 4, except that the shoulder 33 of the stool 2B is set inwardly relative to the outer face of the sash, and the groove 26 is correspondingly spaced farther inwardly. channel 34-is formed in the upper V liquely disposed atsubstantially the same angle as the oblique ducts 35 so that if they should become clogged, they may readily'be cleaned by r p a straight wire or equivalent instrument from. the inside of the house. The sloping wall of the channel 34 also facilitates brushing dirt out of the channel. i I I The application of my weather stripping to the instance of the hinge edge of the sash, as shown atthe right hand of Fig. 2, is structurally similar to that employed at the latch edge, but'the operation is different. At the latch-edge, the sash moves relatively to the frame in a direction toward the shoulder 23. At the hinge edge, on
the other hand, the closing movement of the sash relative to the frame is not toward the shoulder 23 but substantially parallel with itand toward the surface 30 of the sashlopening. In
providing for this different character ofrelative movement of the sashfandframe; I use the same groove 26 in the sash and-groove 29 in the jamb,
. and I position the weather stripping the same way;
but instead of having theweather stripping caropposite regions.
they are not aligned.
ried by thesash it is carried by the frame. Thus the nails. 21 are driventhrough the portion I2 of the Weatherstripping and into'the jamb adjacent the sash opening 30. In this case the U -shaped portion 12 of the weather stripping permanently occupies the groove 29, and because 7 it is normally wider than thegroove 29,.resiliently seals against the walls of the grooves at two The :U-shaped portion .Il removably enters the groove 26. The fully opened position is shown in Fig. 6. Becaus'e the groove 26: is' of slightly less width than the normal width of the U-shaped'po-rtion II, when the stripping'at the several corners of the sash, so as to prevent leakageof air at the corners." At the corner where the top" weather stripping and the latch edge weather stripping meet, as shown in Fig. '7, I employ a simple miter joint'which is not soldered or brazed. Where the bottom weather stripping and the sash .siderweather stripping form a'corner, as illustrated in Fig. 5,
The bottom edge of the sashedge weather-stripping extends to the top edgeof the face of the stool above the shoulder 33. The-bottom weather stripping simply extends to and terminates in the plane of the latch edge of the sash. However, the space designated by; 36 in Fig. is filled by the portion of the stool 31 of Fig. 4 which also seals the bottom end of the edge weather strip.- ping. Fig. 6. shows the disposition of the weather stripping at the bottom hinge corner 'of the sash, where the end of the frame-carried weather stripping abuts the portion 3'l'of the stool and the hinge end of the bottom weather stripping comes againstthe surface 30 of the sash opening; At the corner formed by the frame carried weather stripping on the hinge jamb and the weather stripping at the top of the sash, the aligned ends of the weather stripping may be mitered somewhat as in Fig. '7 with this diiference, that one is carried by the frame and the other by the sash whereby they come into miter corner relation only when the sash is closed.
Where, instead of a single casement'sash in the sash opening of a frame, there is a pair of casement sash, weather stripping mustbe pro vided at the meeting vertical rails of the two sash.
' Patent No. 1,930,801 of October 17, 1933, on Window frames. So that the groove in the blind stop which accommodates my weather stripping will not interfere with ample support for the base ofthe tongue of the interlock 41 the latter is shifted inwardly'from the face of the jamb.
The lower sash 48 is mounted in the frame between the inside stop 44 and the parting stop 46, while theouter or upper sash'is mounted in the frame between the parting stop 46 and the blind stop 45. i The sash are free to reciprocate vertically in the usual manner, being balanced by the sash weights 50 and sash cords 5| which pass over sash pulleys 52 journalled in pulley frames 53set into the face of the side jambs;
It is a feature of my invention that my weather strippingcan be-and in fact preferably is, as
is'here shownapplied todouble hung sash so that the weather stripping stands in the same position relative to the sash and frame as in the application to doors or casement windows. Thus, as shown in Fig. 10, the lateral edge of each sash is provided with a groove 54 spaced inwardly from the face of the sash by the width of the web {3. The U-shaped portion H of the weather stripping enters the groove 54. The U-shaped portion l2 enters a groove 55 out into the face of the blind stop 54 which contactsthe face of the sash. As shown in FigplO the pulley frame 53 is preferably set, transversely of the width of the side jamb, at such a position thatitsprotruding hood portion is'contacted by the adjacent edge of the flange llc. l
This helps to position the weather stripping. While the weather stripping may if desired be nailed or otherwise fixed to the side lamb 1 or to the blind stop, it is not necessary that this be done. Onthe contrary, I find it sash tends to position it. To remove the weather stripping, the sash may be moved to its lowermost position, and its unfixedupper end of the strip may be pulled out and the'entire strip drawn upwardly withdrawing it from its grooves in the sash and the blind stop. The flexibility of the weather stripping permits this. The fact that the side weather stripping is not fixed to the frame-or sash greatly simplifies the, operation of removing the sash where the outside stop would have to be removed.-
: Thou-shaped portion H of the lateral weather stripping for the lower sash 48 is received in a similar groove 55 on the inside stop 44.
I In the instance of the sash groovesfi as well as in the instance of the stop grooves 55 and 56, the grooves are of slightly less width than the normal width of the U-shaped portion of the weather stripping which they receive. Conse-. quently the weather stripping exerts a spreading action and results in a two-point seal at any transverse section of the groove. Because of this rela-1 tion a slight transverse movement of the sash, while it might similarly transversely move a floatingweather strip, does not substantially affect the seal of the weather stripping with the groove and the stop. The floating weather stripping and the compressed fit of the U-shaped portions of the weather stripping in the grooves make possible a relatively loose fit of the reciprocating sash between the stops without impairing the quality of the seal afforded by the weather stripping, Ample clearance for the sash may be provided to forestall its sticking without impairing the weather tightness of the window as effected bythe weather stripping. The weather stripping also acts with a mild braking effect on the sash as it is reciprocated, thus avoidingthe falling of the sash if the weights are not adequate. This braking effect is the result of the friction developed by the slight spreading action of the U-shaped portions ll of the weather stripping which work in the grooves 54 of the sash.
In the upper edge of the upper sash a groove 5'! similar to the grooves 54 is formed. As the upper sash is closed, the groove 51 receives the U-shaped portion H of the top weather strip,'as shown at the top of Fig. 9. Here the U-shaped portionlZ of the weather stripping is received in a groove 58 in the top blind stop 45. The top weather stripping may be held in place by nails 59 driven through the web portion l3 into the head jamb 4!. Otherwise there would be nothing to hold the weather stripping in position when the upper sash was down except the friction of the U-shaped portion which enters the groove 58. Nailing the top weather stripping to the head jamb or the top blind stop .does not interfere with removal of the sash.
For sealing the bottom of the lower sash, the U-shapedportion E2 of the lower weather strip is received in a groove 69 formed jointly in the stool and sill. Here also, the weather strip is prefer ably nailed to the frame. As the lower sash is closed the U-shaped portion l l of theweather strip enters a groove 8! in the bottom of the sash which is similar to the side grooves 56. While the lower'weather strip is not floating, the upper part of the U-shaped portion ii is rounded so that it tends by a camming action ,to pull the lower end of the sash into proper position if the sash be loose in the frame. Failing this, the inherent flexibility of the weather stripping would permit the necessary slight deformation in the cross section of the weather stripping toinsure its entering the groove and making a weather tight seal against the walls thereof. The same action is true of the top weather strip.
The shallow depression cut adjoining the groove, for the reception of the flange l 20 of the strip, is somewhat deeper in the instance of the top and bottom of the double hung sash than in the instance of the casement sash. This is to eliminate danger of the flange l2c being caught by the corner of the double hung sash as it moves past the flange l2c. Also, as will be seen froma close inspection of Fig. 1, the flange E20 is at a slightly acute angle to the leg IN). This tends to-draw the raw'edge of the flange I20 further into its depression.
7 In the instance of the inter-sash seal-the seal between the top of the lower sash and the bottom of the upper sash-the relation of the weather stripping to the sash is somewhat different than in the other applications heretofore described. Referring to the metal section of Fig. 9, the top rail of the sash 48 has a down-facing shoulder 62 which, when the two sashes are closed, overlies and rests against an up-facing shoulder 63 on the bottom rail of the upper sash 49. A groove 64 is formed on the outer face of the upper rail of the sash as and below the shoulder 63. In this groove 5 is secured, as by nails, the U-shaped portion 1! I of-the inter-sash weather strip. The strip is thus carried by the sash 49 with its U-shaped portion l2 extending upwardly above the shoulder 63. The u-shaped portion I2 is received by a groove 65 formed in the shoulder 62 cf the lower sash 48.
The slight'obliquity between the surfaces which carry the weather strip and the direction of movement of the sash, in the instance of the bottom and the inter-sash sealing strips, is absorbed in the resilience of the material of the strip.
The'weather strips for the sides of the lower sash and for the bottom of the lower sash are co-planar; therefore their corners may be mitered at the lower ends of the lateral strips. The same is true of the upper ends of the lateral strips for the upper sash G9 where they meet the top strip. These are the meeting corners of the weather strips which have to be sealed when the sashes are closed. Mitered corners can be made substantially weather tight. The ends of-the inter-sash weather strip come against the inside face of the'lateral parting stops 66.
:As previously stated, my weather stripping does not interfere with the removal of the sash from a double hung window. To remove-the sash, the retaining screws 66 for the inside stops 4 are removed and then the stops themselves are removed. By lifting the lower sash 38 a little, the sash together with its lateral weather stripsmay be pulled inwardly, that is, toward the room. Or, as previously described, the lateral strips may be withdrawn upwardly. Then the parting stops 46 may be removed, the lateral weather strips for the upper sash may be withdrawn as previously described and that sash removed inwardly. The bottom strip and the top strip are left undisturbed on the frame. The inter-sash strip is carried by the sash 49.
If the sash be fitted to the frame at the factory, the grooves may initially out to the most advantageous depth. However if the sash are made slightly oversize to be fitted to the frame by the carpenter on the job the grooves 54, 57, and El may be made as much deeper as the sash is made oversize. An excessive depth to these grooves will not impair the functioning of my weather stripping.
- While I have described these specific embodiments of my invention I contemplate that changes may be made therein and other applications made of my weather stripping as well as changes in my weather stripping, without departing from the scope or spirit of my invention.
In the claims, for lack of a better term, I have used fenestral in the broader sense of pertaining to doors and door frames as well as swinging or sliding windows and window frames.
