9 Claims.

This invention relates to window construction and more particularly relates to double hung or sliding type windows.

One of the objects of the invention is to provide new and improved types of double hung windows having improved weather stripping to secure absolute tightness from the weather, and at the same time insure easy sliding operation.

It is a further object of the invention to provide a. double hung window construction in which the mounting of the sashes will allow for lateral movement, permitting removing of the sash without requiring removal or displacement of any part of the jambs.

It is a further object of the invention to pro vide an improved mullion construction for multiple windows.

Other objects and advantages of the invention will appear from the following description of certain preferred embodiments of the invention chosen to illustrate the principles thereof.

In the accompanying drawings:

Figure 1 is a fragmentary front elevation of a multiple window embodying the invention;

Figure 2 is a vertical section on line 2-2 of Figure 1;

Figure 3 is a horizontal section on line 3-3 of Figure 1;

Figure 4 is a vertical section of a window showing a modified form of the invention;

Figure 5 is a horizontal section of a window showing a jamb applicable to either the forms of Figure 2 or Figure 4 and showing sashes of the type shown in Figure 4; and

Figure 6 is a horizontal section of another modified form of sash and jamb, the form of jamb shown being also applicable to receive sashes of the form shown in either Figure 2 or Figure 4.

Referring to the drawings in detail and particularly Figures 1 through 3, the window frame shown comprises a header I 0, sill II and jambs 12. The header l0 includes a channel-shaped member having upwardly extending flanges I3 and It at its inner and outer edges, the flange I3 being on the inside of the window, and bein the shorter of the two. Intermediate these flanges is a downwardly extending rib I5, and extending downwardly from the outer edge of the header and preferably in the same plane as the flange I4 is a flange I 6 which terminates in an inwardly turned portion I1 and acts as a weather guard for the upper portion of the window. The upper sash rail is arranged to engage with the header and includes a hollow extruded portion 20 having pane the flange 2| on the inner side thereof, and the undercut flange 22 on the outer side thereof,

. which is arranged to key with the putty. If desired, pane clips 23 may be used throughout the glazing to improve the stability of the window pane 24.

Extending upwardly from the hollow member are the header engaging flanges 25 and 26 having lugs 21 and 28 respectively mounted on their inner sides.

Mounted upon the top horizontal wall 28 of the hollow rail member 20 and secured beneath the lugs 21 and 28 is a triangular shaped resilient non-corrosive sheet metal weather strip, the legs of the weather strip 30 and 3| terminating in outwardly turned edges 32. It will be seen that when the window is thrust into its highest upward position the flanges 25 and 26 will engage the face of the header l0 and the downwardly extending rib IE will enter between the legs 30 and 3| of the weather strip. Sufficient spring pressure is provided in the weather strip to insure a tight weather proof sealing on either side of the rib IS. The edges 32 are flared sufliciently to permit the rib l5 to enter between them, but are preferably curved no more than is required for this purpose and should not for instance be headed over. Thus the longitudinal flexibility of the edges is largely preserved and a better sealing contact is obtained throughout the length of the rib I5 than would be the case if the edges were so formed as to have longitudinal rigidity. The top rail member 20 of the upper sash is preferably formed with an inwardly projecting flange 33 constituting a continuous sash pull. The flange also serves the additional function of reinforcing the top rail member since it changes the center of gravity of the rail and relieves the intensity of direct stresses and strains on the rail.

The meeting rail assembly comprises the upper and lower hollow extruded rails 35 and 36, respectively. The upper meeting rail 35 includes an inwardly extending flange 31 having an upwardly extending web 38 near the inner end thereof terminating in the bevelled edge 39. The lower meeting rail includes an outwardly extending flange l0 terminating in a downwardly extending web 4| having a bevelled edge 42 adapted to engage with the bevelled edge 39 when the window is closed. The rail 36 has an outwardly extending flange 43 terminating in an upwardly turned lip 44 the bottom of which engages the flange 31 on the top thereof when the window is closed. The lower flange l3 forms with the upper flange a carrying members on one side thereof including pocket in which a V-shaped resilient metal weather strip is mounted having a base 41, a vertex 48 held behind the lip 44 and a freely movable tongue portion 49 held from unlimited movement when the window is in open position by the web 4i and engaged in tight sealing relation with the upper meeting rail by the web 38 when the window is closed.

As shown in Figure 2 the sill comprises a single metallic extruded portion having an apron 50 and a step portion 5! and terminating at its inner side in upwardly sloped portion 52 having a downwardly extending flange 53 which can be secured to or supported upon the wall structure. The sloped portion 52 is particularly adapted to receive condensation from the inside of the window and to direct it off harmlessly to the outside of the building.

The lower sash rail which engages the sill includes the inner wall 55 having a lower web 56, a downwardly extending flange 51 terminating in an outwardly turned lip 62. The flange 5] engages directly with the step portion of the sill when the window is closed and a downwardly extended outer flange 58 having an inwardly turned flange 59 which engages the riser 60 of the step portion of the sill when the window is in closed position.

To insure absolute tightness of the window with the sill a V-shaped metallic weather strip member is provided having a base 6| which engages the bottom web 56 of the rail. The vertex 55 of the V is held under the outwardly turned lip 62. The other arm 66 of the V is a freely movable tongue held from unlimited movement when the window is open by the flange 59 and engaged by the top of the step portion 60 of the sill when the window is closed.

The sill also includes a downwardly extending flange I at its outer extremity beneath which a caulking pocket iI may be provided and also has an intermediate leg I2 which rests on the masonry, supporting the sill and providing a back for the caulking pocket.

Referring to Figure 3 the jamb I2 is shown as a channel shaped member having outwardly extending inner and outer flanges I5 and I6 terminating in inwardly and outwardly extending portions 11 and 18 which are adapted to key with the masonry. The jamb also includes the 'part ing strip 19 formed therein and on the inner and outer side thereof, flanges 80 and 8| having outwardly and inwardly extending stop beads 82 and 83 respectively. Intermediate each of the flanges 80 and III and the parting strip are situated the guide ribs 85 and 96 respectively for engagement with the sash rail in the manner to be described.

The sash rail of the inner sash includes the web 90 having the pane engaging portions on one side thereof similar to those described in connection with the top rail, and having an inner flange 9I extending from the inner side of the web. The flange 92 terminates in an outwardly turned lip 93 which bears against the parting strip 19 and provides firm sealing contact between rigid members. The flanges 9I and 92 will be in reverse position on the opposite side of the parting strip as shown by the partially removed sash in the lower portion of Figure 2. Each of the flanges 9I and 92 contains on its inner side the ridges 95 and 96 and outwardly of said ridges the undercut ribs 91 and 98. Mounted between the flanges SI and 92 is a triangular shaped metallic weather strip having the two base angles of the triangle held respectively between the ridge 95 on either side of the guide ribs and 86 in sealing sliding relationship.

It will be observed that considerable lateral movement of the sash between the jamb membersis possible and as shown in the lower part of Fig ure 3 the sash may be removed by sliding it toward one jamb which will cause disengagement of the legs of the weather strip at the opposite side of the sash from the flange on the opposite Jamb and also carry the flanges 9| and 92 clear of the stop bead 93 whereby the sash may be removed.

Where it-is desired to mount a series of multiple windows a mullion I05 may conveniently be provided by combining two of the heretofore described jamb members I2 as shown in Figure 3.

The two jamb members forming the mullion may be secured together by any convenient means, but we have found it convenient to use a channel member, having a base I06 and flanges I01 and I08 which form the sides of the channel having a further flange I09 extending in the same direction between said flanges I01 and I08. The flange I09 extends between the outwardly extending flanges of the two jamb members H0 and III which are comparable to the outwardly extending flange I8 of the jamb I2, and terminates in the holding portion I I2 which may take any convenient form. The channel member which holds the two jambs in place as a mullion may be conveniently fashioned by extruding in one piece.

Referring now to Figures 4 and 5 the modification of the invention shown in these figures includes a header member of rolled sheet metal I20 preferably of non-ferrous or non-corrosive metal which is folded between its ends to provide a rib I2I for engagement with the top rail of the upper sash and formed at its edge toward the outside of the window with a flange I22 terminating in an inwardly directed lip I23. The header member I20 may be mounted upon and reinforced by an angle plate I25 which may be of iron or non-ferrous metal and which is preferably provided with an inner flange I26 and with a wide outer flange I21 which may be imbedded in the masonry or attached to lintel I28 in any suitable manner as by screws or rivets I29. The angle plate I25 may, if desired, be spaced from lintel I28 so as to provide a pocket for caulking material I30.

The sill of the window may be of any suitable form. For instance, as shown in Figure 4, it comprises a plate of non-ferrous or non-corrosive metal having an inclined apron I32 which terminates at its forward edge in a downwardly projecting flange I33. Near its inner edge the sill has a folded rib I34 for engagement with the bottom rail of the lower sash. This non-corrosive metal sill plate is preferably supported and reinforced by a flanged plate I35 and braces I36, which may be made of iron or of non-corrosive metal as desired.

The window jambs are preferably of the form shown in Figure 5 and each comprises a channel member I40 preferably made of non-ferrous or non-corrosive metal, said channel being provided with an inner flange I4I having a lip I42, and with an outer flange I43 having a lip I44. Substantially centrally of the bottom of channel I40 an inwardly projecting rib I45 is provided, and fitted over this and secured in any suitable manner, as by screws I41, is a channel shaped parting strip I48. A pair of sash receiving channels is thus provided. Formed in the bottom of each of these sash receiving channels is an inwardly projecting sash guide rib I50 which is preferably of considerable width so that it projects well out from the bottom of the main channel member I40, and nearly as far as the lips I42 and I 44.

For reinfohcing the jam channel I40, a reinforcing plate I55 is preferably provided which is secured to the back of the channel I40 in any suitable manner, as by welding or by means of screws or rivets, and which comprises an angle web I56 and a flange I51, the latter being preferably parallel to the plane of the window. Braces I58, which may be punched out of web I56, connect the flange I51 with the back of the jamb near the flange I43 so as to hold the angle web I56 rigidly spaced from the channel at th proper angle. A very strong construction is thus provided which renders the jamb rigid and is adapted to interlock and bond the masonry.

The sashes comprise stiles which may be extruded from aluminum, or bronze or other suitable metal, each stile having a base I60 suitably formed to hold a pane of glass and carrying an inside flange I6I terminating in a lip I62 and an outside flange I63 having a lip I64. Inwardly projecting from the flanges I6I and I63 are intermediate ribs I66 which are located at a distance from the base I60 of the sash stile. Mounted between the flanges I6 I and I63 in the space defined between the lips and ribs on the flanges is a resilient metal sash guiding and sealing strip which may desirably be formed of non-corrosive metal such as bronze or stainless steel, and which comprises a transverse base I10 supported on the ribs.

I66, side flanges I1I extending from the base to just below the lips I62 and I64 and inwardly directed resilient tongues I12 which are adapted to bear against the sash guiding rib I50 with sufficient pressure to form a weather tight seal. The faces of the sash stiles adjacent to the parting strip I48 normally bear against the parting strip so as to form close metal to metal contact, and the seal thus effected, in addition to the seals effected by engagement of the tongues I12 with the guide rib I50, form a triple barrier against the weather. The sash, however, being held in position only by engagement with the resilient tongues, cannot bind, jam or rattle. The construction described permits removal of a sash either by sliding the resilient sealing member endwise out of its recess in the sash stile, or if desired, the sash may be taken out without removing any part by simply forcing the sash laterally in the plane of the glass to an extent sufiicient-to permit one stile of the sash to clear the lip I42 past the edge of the guide rib I 50, whereupon the sash may be removed. Owing to the space between the base I60 of the sash stile channel and the base I 10 of the guiding and sealing member, the latter can be sprung sufliciently to permit the necessary lateral movement of the sash, as clearly shown at the lower part of Figure 5.

The top rail of the upper sash comprises a hollow extruded section, preferably having a partition I13 across the same which supports a resilient metal weather sealing member similar to that used in the stiles of the sash, and which is adapted to engage the rib I2I. When the sash is moved down so that the tongues I12 leave contact with the rib, the edges of the tongues spring together, thus closing the space in the channel below them against the entrance of dirt. The bottom rail of the lower sash is preferably of similar section to the top rail of the upper sash and carries a similar weather sealing member which engases with the rib I34.

The meeting rail of the lower sash is preferably formed to provide a laterally projecting channel member I14 which is adapted to hold a weather sealing member of the same shape as those used elsewhere in the sashes. This meeting rail is also provided with a laterally projecting narrow flange I15. The meeting rail of the upper sash is provided with a laterally projecting flange I16 adapted to engage under the flange I 15 when the meeting rails meet, the flange I16 carrying an upwardly projecting rib I11 adapted to project between the tongues I12 of the sealing member so that a three point seal is provided at the meeting rails. The channel I14 and resilient sealing member are preferably carried on the meeting rail of the lower sash as shown, so that they will face downwardly and will not collect water and the springing together of the edges of the tongues I12 when the rib I" is withdrawn from contact therewith by the opening of the window also helps to exclude dust, etc. It will be seen that the sealing members may be of like cross section throughout and that they are held in position on the sash members by the flanges of the sash, thereby dispensing with the use of screws or other fastening means. The weather sealing means may also be removed without dismounting any part of the frame or destroying the sealing means themselves.

In Figure 6 a further modification of the window of this invention is shown in which each jamb is formed of a channel I at each edge of which is a flange I8I terminating in a lip I82. The central part of the channel is off-set as indicated at I83 and the sashes are guided by two guide ribs I84 connected by a web I85. The member comprising the ribs and web is removably secured in place in any suitable manner as by screws I61, and is divided horizontally near the center of the window into two parts to facilitate removal. The removal of the guide rib members permits removal of the sashes and also provides access to the counterbalancing means indicated at I88. The sash stiles are of channel form and each comprises a base I carrying glass and putty retaining means and inner and outer flanges I9I and I92 which have lips I93 at their edges and lugs I94 placed a short distance from the base I90. Sash sealing and guiding members of resilient material are mounted in the stiles and in the form shown comprise a curved base I 95 adapted to contact with the inner end of a guide rib I84 and two inwardly bowed tongues I96 adapted to engage the sides of the guide rib. Relatively acute bends 200 connect the tongues with the curved base I95, these bends interlocking beneath the lugs I94 and the edges of the tongues being retained behind the lips I93. The sash guiding members are thus firmly retained in the sash stiles, In this construction it is seen that there are three points of sealing engagement between the sealing and guiding members and the sash guide rib, namely the two contacts between the sides of the rib and the tongues and the one contact between the end of the rib and the center of base I95. All of these contacts are weather tight but yielding so that the sash floats freely and slides easily without binding or Jamming.

For reinforcing the jamb members of the frame and assisting in securing the frame in the wall, a reinforcing member of the form shown in Figure 6 may be employed. This member comprises a flange 220 adapted to be secured to the jamb channel I80 in any suitable manner, as by being fitted under tongues 22I bent out from the back of the oifset portion I03 of the channel member I80. Adjacent to the flange 220 the reinforcing member has a shoulder 225 which seats against the end of the offset portion I83. The reinforcing member has an inclined web 221 which is preferably inclined at a considerable angle to the plane in the back of the jamb channel. The inclined web 221 preferably carries a web 228 parallel to the plane of the window, this web being of any desired width to give the necessary strength and for engagement with the masonry. The inclined web 221 is preferably braced in position by means of braces 230 formed integral with or attached to the web 228 and secured to the flange I8I of the jamb I80, by suitable means such as screws or rivets 232.

This application comprises in part subjectmatter divided from applicants applications for patent, No. 243,931 and No. 243,932, flied December 5, 1938.
