33 Claims.

This invention relates to window constructions, and more particularly to windows of the sliding sash type, an object of the invention being to provide such a window which would be 5 weatherproof when the sashes` are closed by reason of the fact that the sashes at their side edges and atA their meeting rails will have a three-point contact, one point of contact constituting a Weather-strip.

1 A further object of the invention is to provide a window of the sliding sash type with sheet metal weather stripping of novel construction which permits the easy sliding of the sash but at the same time renders the window weather 15 proof and prevents rattling.

A further feature of the invention has to do with the construction of the meeting rails of the sashes. In accordance with this feature the meeting rail of the lower sash is provided at its lower side with a down turned lip and the inner portion of the meeting rail of the upper sash is provided at its lower portion with an upturned lip adapted to extend around and engage against the lip of the lower sash. The meeting rail of the upper sash is also formed to house aweather strip which includes a resilient tongue, the free end of which normally `engages the outer face of the lip or flange carried by said rail. When the Window is closed the lip carried by the meeting rail of the lower sash wedges between the lip of the upper sash, and the Weather -strip forcing them apart and causing firm sealing engagement to be had at both the inner and outer sides of the lower sash lip.

The meeting rail of the lower sash is further provided with an outwardly extending web which is adapted to extend over and engage the top surface of the extension of the meeting rail of the upper sash which houses the weather strip. This affords a still further point of sealing contacts and affords added assurance against ingress of rain or snow.

A further object is to provide a window construction in which the sash chains or cords are concealed.

A further object is to provide a Window construction having a novel arrangement of shapes in the frame and the sash members, all of which result in a strong, durable and more or lessy inexpensive construction With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter 55 described and pointed out in the claims.

In the accompanying drawings- FigureV 1 is a lview in elevation on a reduced scale of the improved window and frame;

Figure 2 is an enlarged broken view in vertical section on the line 2--2 of Figure 1;

Figure 3 is a fragmentary view in horizontal section on the line 3-3 of Figure l; i

Figure 4 is a fragmentary view in horizontal section on the line 4-4 of Figure 1;

Figures 5, 6 and 7 are perspective views illustra'ting the various shapes of weather-strip which are employed in the construction.

Referring to the drawings in detail which show one preferred embodiment of the invention chosen to illustrate the principles thereof- I represents the sill member of the frame, which may be secured to the masonry structure by well known types of knees 2', and upon or at the ends of this sill member i anchors or corner braces 2 are secured. Flrmly secured to the anchors' or corner braces 2 are inner vertical frame or jamb members 4 which are preferably oi.' channel shape. At the sides of the jamb'members towards the exterior of the building the jamb members are bent intoprojecting hollow or box-like form which may be referred to as a hollow flange 62. At the top of the frame is an upper frame or head member 9 which is also ofl channel shape like the jamb members 4 and 'which has a hollow fiange- 63 at the side thereof towards the outside of the building. f i

Sheet metal weight boxes 3 are attached to the jamb members 4, the forward edges of the'weight boxes preferably being bent upon themselves as indicated at 65 and 66, and being secured to the frame members 4 by'screws 6. 'I'he bent over forward edges 65 of the weight boxes are secured in the hollow flanges 62 as shown in Figures 3 and 4. Extending across the head of the window frame is a box member 3 similar to the weight boxes 3', the edges of this member 3' tting into the channelled head member 9. The 4weight boxes 3 and box member 3' extend continuously around three sides of the window frame as shown in Figure 1,- and constitute with the upright frame or jamb members 4 and head member 9 a strong and rigid buck capable of retaining its shape during transportation and use.

Mounted within the inner frame members 4 are outer or exposed frame orvjamb members 5 which may be extruded, drawn, or otherwise suitably formed, preferably of non-corrosive metal. These inner and outer vertical frame members 4 and 5 form vertical chambers 1 in 20, ceive condensation and which chains I, `connecting therespective sashwith the ordinary weights in the weight boxes, are housed and hid from view and protected from the weather. 'Ihe head member l of the which may be drawn or extruded, and so de-l signed that it will provide on the outside ofthe sash an inclined water table `on whichno water will stay,` and on the inside of this sill is provided with a groove or condensation gutter I to reprotect wood or any otherv stool vfrom dampness. g

The inner frame plate I has a removable section l' to permit access to the weight boxes, the means for securing this removable section being a modification of the construction described in detail in our co-pending application, y.Serial Number 691,552, led September 29th, 1933. Inthe construction shown one edge of the removable section l' is received in a notch formed by the -30 edge .of the bent over box portion Il, the edge of the strip 5" and the edge of the member carrying the stop bead 31. 'Ihe other edge of the removable section 4' extends under the member carry-V ing the parting strip and is secured thereto 35 by one or more of the screws 30. The stop bead, of course, extends the entire height of the window and therefore is ilrmly secured in place to the lamb above and below the opening closed by the removable section 4'. 'I'he section I may be removed when desired by taking ofi' the sections of v the jamb carrying the vstop bead 31 and, the

partingstripll.

The outer. or exposedframeorjamb members l are, as illustrated in Figures 3 and 4, formed in three vertically extending sections, separately Aremovably secured tothe inner frame members- I. 'I'hese three sections comprise a ilrst section carrying an inner stop bead 31. 'Ihissection inthe form shown has on its side towards the l'which is clamped against a strip l" by means inner stop bead 31 has a pocket Il .in its inner face in which is mounted a resilient weather strip II.- As illustrated, particularly in Figure k7 the weather strip is 'preferably formed of a resilient sheet of metal bent along a longitudinal line so as to provide two separated walls, one of which is seated in the pocket in the frame member, and the other of which engages the sash. It is important that the sash engaging wall of the strip be substantially smooth or fiat so as to have substantialflexibility and resilience so that it may follow the movements of the sash and nt irregularitiesoi the sash or frame. The edge of this lby a bead or curl or the like and therefore may be termed a raw edge, that is, unbeaded or interior of the building an integral angle portionV vwan of the weather amp is preferably unstmened f #,oss'szssA y Y.

erably formed as an integral thereof.

parting strip preferably carries'V projecting sash engaging anges Il. (Fig. 4.) section of the iambis removably held in place by screws Il. The portions `of the lamb sections carrying inner stopgbead 31 and parting strip which extend towards each other and form the bottom of the sash-receiving channel are spaced apart so as to provide a narrow slot-I3 adaptedI to receive. a flange projecting from the edge of `a sash as will be described below.

'I'he third section of the outer frame or lamb member I carries an outer stop bead I6, the portion of this section atv the bottom of the sash receiving channel being spaced from the adjacent edge of the central Jamb section to provide a space `33 vfor a sashrnange. 'I'his third section of the outer Jamb l is provided with a portion 00 which covers the hollow flange l2 of the innerl frame .member l, this section of the outer Jamb being secured in position by the screws l. The

This parting strip' outer stop bead 36 has ls. pocket `Il! in its inner face which receives a resilient weather strip Ill similar to that already described. As shown in Figure 4, the free wall of the part of the weather' strip when not in engagement withthesashsprins outwardly until ythe edge of the weather strip engages the shoulder 8| adjacentvto the stop bead and forming part of the pocket 40, which shoulder protectsthe edge of theweather strip, holds the outerwall oi' the strip under tension and assists in retaining the weather strip in its pocket. The outer margin of the portion 80 of the member carrying the outer stop bead 3l preferably is extended into an undercut flange I2 which forms a pocket adjacent to theouter wall of the building for receiving and retaining caulking material n.

A'and B represent the upper and lower sliding sashes respectively, and as the frame members of these upper and lower sash'es are dinerent in shape in cross section they will beiseparately described and given different characters of reference. All ofthe frame members of both sections are preferably hollow and maybe formed by extruding metal or they may be otherwise formed 'if desired, and the upper horizontal bar Il of the sashAhasagrooveMinitsupperedgewith.`

tapering wall i5 to engage the wedge-shaped ilange I2 at the top cross bar and force the upper `member of the sashagainst a iiange Il' on the partingstrip H to ensure a weather-tight antirattling i'it.l The lower cross bar I8v of the upper sash A-is made with apair vof ilanges Il and Il which together form a groove or recess `for tl'ie accommodation oi' a weather-strip I9, and the lower rail II of the upper sash and the upper rail .20 of the lower sash have inter-engaging inclined or bevelled flanges 2i and 22 respectively,

which,` when in engagement, form a smooth metal-to-metal contact holding the sashes tightly to-y gether; furthermore, the ange 2l engages the free resilient yportion 23 of the weather-strip i9 and the top wall or web 2l ofthe bar 2l `engages over the ilange i1 so that at the meeting railsor bars there is a three-point contact, one contact constituting a resilient weather-strip.

The lower horizontal bar 25 of the lower sash B has outer and inner integral ilanges 26 and ,'21

respectively, which engage' opposite sides of a raised portion 28 on the sill member I.- One of these anges 261s preferably bevelled or inclined engaging a correspondingly shaped face of the raised portion 28, forcing sash against the 'part ing strip' making the contact air tight. The bar 25 in its lower face accommodates and holds a weather-strip 29 with a downwardly and laterally directed resilient portion 30 which bears againstthe upper face of the raised portion 28, and thus at the sill there is also a three-point contact, one of which constitutes a resilient Weather-strip. The portion 30 may slide on the portion 28, as the flange 26 performs its function. .Side bars 3i of both sashes A and B have integral flanges 32 which move in slots 33 in the 'outer side frame members 5 and project into the chamber 1 and have attached thereto the chains 8. Thefacesof the sashes adjacent to the parting strip engage the edges of the flanges 38 on the parting strip, while the opposite faces of the sashes are provided with ribs or beads 42 which engage the resilient vweather strips 4| so as to render the engagement between the sashes and the frame weather prooi'.v

As it is desirable to close the slots 33 in the frame members 5 below theupper and outer sash A, a movable strip 43 is located in the chamber 1 and normally positioned across the slot 33. i This strip 43 is connected by springs 44 with a wall 45', which springs normally urge thel strip 43 into a V-shaped groove 45 in the frame 5 and close the slot 33 below the upper sash. 'I'he upper end of the strip 43 is bevelled or inclined as shown at 4E, in Figure 2, so that when the upper sash is lowered its flange 32 will engage this inclined or bevelled end 4B and force the strip 43 to one side, allowing the strip to move down in the slot 33. When the sash is moved upward to its closed posi- -tion the strip 43 will again spring back to normal position, closing the slot 33.

Bumper plates 41 and 48 respectively. are secured to the frame members 5 to limit the downward movement of the upper sash and the upward movement of the lower sash, as will be readily understood. In other words, the plates 41 are extended across the slots 33 and are engaged by the ilanges 32 so as to limit the movement of the sashes.

The panes of glass 49 in the upper and llowe sashes are tted in grooves 50 in one bar, and the other three edges of the panes of glass are fitted in similar grooves, provided by integral flanges 5I and removable angle strips 52 on the side and bottom bars of the sashes. As illustrated the glass in the grooves is enclosed in suitable packing 53 so as to make a tight juncture between the parts without a strain on the glass.

It is noted that our improved window construction having its arrangement of steel frame members 4 and 9 and weight boxes 3 and lintel box 3' which, as a matter of fact, form a complete buck, presentsa strong rigid construction. In this arrangement of parts the weather strips insure a resilient weathering contact. The improved automatic slot closing device prevents the entrance of rain and moisture tothe interior of the frame, and a special tubular construction with weathering lips or flanges thereon creates a neat and economical construction.

While we have illustrated what We believe to be the preferred embodiment of our invention, it is to be distinctly understood thatvarious slight changes may be made with regard to the form and arrangement of parts without departing from our invention, and hence we do not limit ourselvesjto the precise details set forth butconsider ourseives'at liberty to make such changes and alterationsH as fairly fall within the spirit and scope-of the claims.
