Application December 5, 1938, Serial No. 243,932 12 Claims. (Cl. 189-72) This invention relates to windows of the sliding or double hung type. One of the objects of the invention is to provide a frame and sash construction in which the frame has a pair of guide rails for each sash, the sashes being provided with resilient sliding contact members adapted to slide upon the guide rails and to seal lthe windows against leakage and prevent rattling. The resilient engagement'is such that while the windows are at all times maintained tight against the weather, the sashes slide freely, so that Athere is no chance of sticking or binding. Other objects of the invention are to provide an improved construction for permitting removal ofy the sashes, improved means for permitting access to the counterbalance pockets, improved means for securing the frames in the window openings of the building, and an improved construction whereby jamb members of adjacent window umts may be secured together to iorm multiple units A back of the channel.

provided with reinforced mullions. Other -objects and advantages will appear from the fol` lowing description of certain embodiments of the invention chosen to illustrate the principles thereof.

In the accompanying drawings:

Figure 1 is a front elevation of a portion of a wall with a two unit window mounted therein, a corner thereof being broken away to'show a detail of sash construction.

Figure 2 is a vertical section on line 2 2 of Fig. 1;

Figure 3 is a horizontal section on line 3 3 of Fig. l;

Figure 4 is a horizontal section on line 4 4 of Fig. 1;

Figure 5 is a horizontal section of a vmodiiied Vconstruction of window;

Figure 6 is a perspective view showing a portion of the jamb member of Fig. 5 illustrating a form of bonding loop for interlocking with the masonry Wall;

Figure 7 is a vertical section of another modi-- 2l, the lips 2l on the opposite flanges being directed towards one another. The lips 21 enclose pockets for receiving counterbalancing means,

such for instance as the drum type spring counterbalances indicated lat 28. When the jamb member is to be mounted directly in a masonry wall, as shown, for example, in Figure 3, bonding means are attached to the back of the channel, so as to project into the masonary. Such a bonding means is shown at 30, and comprises a corrugated strip of metal embedded in the masonry and having a flange 3| at its end adapted to be attached to the back of the channel in any suitable manner, as for instance by being inserted behind a tongue 32 bent out from the When two adjacent window units are to be mounted together, as shown in Fig. 1, then the two jamb channels are placed back to back, as shown in Figure 4, and are secured together by means of cover channels 35 which lt over the adjacent flange portions of the jamb channels and may be secured in position in any suitable manner, as by means of screws or'rivets 36. In this way a Very solid mullion is secured and a smooth finish is provided between the two window units. If the window is high and extra strength is desired, a reinforcing bar 31 may be enclosed in the space formed by the off-sets-in the backs of the two jamb channels. e

The header member 2| shown in Fig. 2 is of metal, rolled or.otherwise suitably shaped to form, and is preferably provided with a turnedover bead 40 at its inner edge, with a central downwardly projecting rib 4|, with a narrow fold or rib 42 and with an outer folded-over portion 43 which protects the outer margin of the sash from the weather and serves as a means for carrying a resilient sealing member 44 for engagement with the top rail of the upper sash. For the purpose of holding the sealing member 44, the horizontal fold of the portion 43 terminates in a lip 45 which engages the outer bend of the sealing member. The header is also provided with a rib 46 against which the back of the sealing member rests. The rib 42 .constitutes a guard and limiting device for the free edge of the sealing member which engages the bead when the sash .is moved down, and serves to retain'the sealing member under initial tension. The edge of the bead 42 also forms a stop to limit the upward movement of the sash.` An angle iron 50 (or series of angle brackets) is preferably secured at its lower end in the inside of the rib 4I, its projecting flange being secured in the masonry or attached to a lintel 5l, in any suitable manner as by means of screws 52.

The'sill 22 comprises a member formed into two steps and 6| and having an inclined por-A tion 62 forming an apron which terminates at its outer edge in a. downwardly turned flange 63. 'I'he sill is completed by a pair of angle plates 64 and 65 secured to the upper step 60 and to the flange 63, respectively. If desired, the sill may be filled with cement for reinforcing purposes. The overhanging portion of the flange 63 forms a pocket 66 for caulking.

For guiding the sliding sashes the jamb members are provided with spaced guide ribs which are preferably united into a single unit by a web 1|. The web 1I is secured to the inner face of the off-set portion 25 of the main jamb channel member and the extremities of the outer legs 13 of the sash guide ribs 10 preferably embrace and flt against the ends of the off-set 25. The webs 1| are removably secured by any suitable means, such as screw 16. The guide members 10 and web 1| are preferably formed in two halves divided along a horizontal line near the middle of the window as indicated at 11 in Fig. 2, so that either half may be removed, thereby permitting the sash to be removed.

The sashes comprise topfbottom and meeting rails which may be of any suitable construction and provided, where necessary, with sealing strips. The side rails of the sashes are channel shaped and carry resilient sealing and guidingmembers adapted to slide upon the guide ribs 10. As shown in Figs. 3. and 4, the sashes are shown as madeof extruded metal and comprise an undercut putty seat 80,. a glass supporting flange 8|, a front flange 82 towards the outside of the window terminating in an overhanging lip 83 and rear fiange84 towards the inside of the Window, terminating in an overhanging lip 85. There is a groove 86 in the bottom ofl the sash channel adjacent to the flange 84. The resilient sealing and guiding member comprises a strip of bent resilient sheet metal or other suitable material which has a base portion 90 seated in the groove 86 andl a flange 9| seated against the inside of the flange 84. The flange 9| terminates in a reversely bent resilient tongue 92 preferably having a raw or unreinforced edge which is received behind and protected by the shoulder 93 formed at the edge of the base 90 adjacent to the wall of the channel 86 towards the outside of the window. The unreinforced edge of the tongue 92 is longitudinally flexible so that it will conform to any irregularities of the rib and form a tight seal therewith at all times. Springing 'from vthe shoulder 93 of the base 90 of the resilient strip is a second resilient,

flexible edged tongue 95 which is adapted to engage the inner edge of the guide rib 10. The resilient tongue 92 engages the inner side wall of the guide rib and serves to hold the sash in such position that the edge of the lip 83 bears against the outer surface of the guide rib. A three line engagement is thussecured between the sash and the guide rib, one line of engagement, namely, that of the edge of the lip 83 being engagement of one rigid part against another, while the other two lines of engagement are with the resilient tongues 92 and 95.` While there are thus three -points of sealing against the weather, nevertheless a limited movementof sash, both in the plane of the glass and transversely thereto, is permitted, so that there can be no binding, and the sash will slide easily at all times and under all conditions. The sealing strips are preferably similarly placed in both upper and lower sashes so that in each instance the engagement between the lip 83 of the sash is on the side of the guide rib towards the outside of the building. Thus the wind pressure on both sashes is sustained by the contact of these rigid members. As the flexible sealing and guiding strip is contained in the edge of the sash and moves therewith, it is never exposed to the elements or to tampering. with, as may occur where the resilient strip is mountedin the jamb and is always partly uncovered by the sash.

In the construction shown, each sash is provided with a bracket |00 for engaging with the counterbalancing means 28. End plates |0| and |02 (see Fig. l) are preferably removably secured to each end of each sash stile channel by any suitable means such as screws, not shown. The weather strips are thus secured in place from accidental displacement and protected from ingress of dirt and moisture'.

Referring to the construction in Figs. 5 and 6 the jamb here shown comprises a bent or rolled metal channel member ||0 having flanges II| preferably terminating in bent-over edges II2,

there being outwardly projecting ribs |I3 formed at each edge of the base of the channel. Near the center, the bottom of the channel is bent inwardly to form a supporting leg I I4 adapted to carry the web I I5 connecting a pair of sash guiding ribs IIS. The web |I5 is preferably off-set to fit over the edge of the leg |I4, and may be removably secured thereto in any suitable manner as by screws I I8. The web and sash guiding member is preferably formed in two horizontal halves as described in connection with the guide rib members shown in Figs. 1 to 4. For reinforcing the jamb and assisting in securing it in the masonry wall, a flange plate or angle |20 may be used, its flanged end being secured in the bottom of the leg I I4. To interlock the jamb with the masonry, a bonding loop |22 may be employed, this loop being shown as comprising a rod bent into loop form and corrugated and having hooked'ends |23 which hook into slots |24 formed in the back of the jamb |I0. The hooked ends |23 are preferably bent at an obtuse angle to the rods as shown so that by hooking them partly or wholly into the slots a range of adjustment between the jamb and the rods built into the masonry is obtainable.

The sashes are shown as formed of extruded metal shapes having means for receiving and holding the glass, each stile having an outer flange |30 terminating in a lip |3I adapted to bear against the outer wall of a sash guiding rib |i6, and an inner straight flange |32. In the angle between the flange |32 and the base |40 are formed a pair of ribs |45 and |46 which are adapted to engage and retain the bent portion |41 of a resilient sealing and guiding member which is provided with two resilient tongues |48 and |49 adapted to engage' respectively with the side and inner edge of the sash guiding rib ||6. The pressure of the tongue |48 against the inner face of rib IIB serves to drawthe edge of lip I3I against the outer face of rib IIE so that a three point sealing engagement between the sash and guide rib isprovided. Two of the points of engagement are yielding, While the third is rigid metal to rigid metal so that while the sash is tightly sealed against the weather, it is yfree to slide at all times without jamming or rattling.

Figures '7 and 8 show a modified construction ofwindow in which eachjamb is formed of a channel |50 at each edge of which is a flange |5| terminating in a lip |52. The central part of the channel is off-set as indicated at |53 and the sashes are guided by two guide ribs |54 connected by a web |55. The member comprising the ribs and web `is removably secured in place in any suitable manner, as by screws |51, and is divided horizontally intwo parts as mentioned heretofore in connectionr with the other forms of the invention. The removal of the guide rib members permits removal of the sashes and also provides access to the counterbalancing means indicated at |58. The sash stiles areof channel form and each comprises a base |60 carrying glass and putty retaining means and inner and outer flanges |6| and |62 which have lips |63 at their edges and lugs |64 placed a short distance from the base |60. Sash sealing and guiding members of resilient material are mounted in the stiles and in the form shown comprise a curved base adapted to contact with the inner end of a guide rib |54 and two inwardly bowed tongues |66 adapted to engage the sides of the guide rib. Relatively acute bends connect the tongues with the curved base |65, these bends interlocking beneath the Iugs |64 and the edges of the tongues being retainedbehind the lips |63. 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 sashlguide 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 |65. All of these contacts are weather tight but yielding so that the sash floats freely and slides easily without binding or jamming. Y

resilient member also having a flange |81 lying inside of the flange |82. Flange |81 is formed at its outer edge with a bend |88 adapted to engage under the reentrant lip |83 to assist in holding the sealing member in its recess. The edge portion of the sealing member beyond the bend |88 is bent upwardly to form a resilient tongue |89 which bears against the outer face lof the top rail of the sash so as to seal the joint at that point. The top rail of the sash also bears against the portion 86 over the bead |84 and the inner face of the sash is held in close engagement with the face of the parting strip |8| by reason of the pressure of the tonguev |89. A

three point sealing engagement with the top rail of the sash is thus secured. When the sash is moved down, the edge of the tongue |89 is limited in its movement by the bead |84 which protects the edge and maintains the tongue under initial tension.

The non-ferrous or non-corrosive header member |80 is preferably attached to and reinforced by an angle member |90 whichneed not be of non-ferrous metal, the members |80 and |90 being secured together in any suitable manner as by screws or rivets 19|. The member |90 may be provided with a-flange |92 at its inner edge which will act as a plaster stop and also add strength to the head of the frame. At its outer edge, the vmember |90 is preferably provided with a wide flange |93 which maybe secured to thev lintel |94 by screws or mounted in the wall. The sill of the window is formed of bent or rivets |95 or otherwise extruded metal, preferably non-ferrous or non` corrosive metal, and comprises an apron portion 200` which is downwardly flanged at its outer edge at and is then provided with an inward off-set 202 which forms a pocket for caulking4 203. Back of the apron 200 the sill is formed- .l member 201 which preferably terminates in a flange 208 adapted to rest on the masonry. The

member 201 constitutes a supporting leg for the sill. and it may be adjusted to project into the.

hollow flange more or less as the construction of the wall may require. It may be held in adjusted position in the hollow flange 206 in any suitable manner, as by welding, riveting orthe like. The.

hollow flange 206 is preferably formed to provide an overhanging hooked portion 2|0 which engages and holds the resilient metal sealing member for the bottom rail of the sash. Such resilient sealing member comprises a base 2|| having an off-set portion 2|2 at its upper'` edge adapted to hook under the overhanging hooked portion 2|0 of the hollow flange. bent to form a fold 2|3 engaging the outside of the portion 2| 0, and a resilient tongue 2|4- adapted to engage the inner face of the bottom rail ofthe sash. When the sash is raised` the lower edge of the tongue 2|4 engages behind the offset 2|5 of the shouldered seat 294, the edge of the tongue being thus at all times protected i and the tongue being held under initial tension.`

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 Fig. 8 may be employed, This member comprises a flange 220 adapted to be secured to the jamb channel |50 in any suitable manner, as by being fitted under tongues 22| bent out from the back of the offset portion |53 of the channel member |50. Adjacent to the flange 220 the reinforcing member has a shoulder 225 which seats against the end of the olset portion |53. The reinforcing member has an inclined web 221 which is preferably inclined at a considerable angle suchv as approximately 45 to the plane in the back of the jamb channel.` The inclined web 221 preferably carries a web 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 preferablybraced in position by `means of braces 230 formed integral with or attached to the web 228 and' secured to the flange 5| of the jamb |50, by suitable means such as screws or rivets 232. y v
