. 4 mm. Thepresent invention'relates to window constructions, and more in particular to a novel ,meta'llic double-hung window construction, and in the construction of the sash or closure members.

Among the objects of the invention is to provide a novel sash construction for a window whereby to provide a weather-tight engagement and mounting of the sash members in the frame. The invention comprehends a construction, which is adapted for use wherever a weather tight closure is desired.

. Another object of the invention is the provision of a novel resilient weathering means closure construction formed of metal and adapted to be mounted in a metallic frame and slidable therein. The invention further comprehends novel details of constructions of the sash or closure members and the frame, and in the means for locking and retaining the sash or closure members in their adjusted positions.

A further object of the invention is the provision of a novel sash construction comprising a pair of sash members slidable upwardly and adapted to be-raised into a well provided therefor in the frame of the window. The lower sash member is provided with means adapted to abut an extending portion on the upper sash member whereby said sash members may be raised as a unit into the well provided therefor in the upper part of the window frame.

Another object of the invention is the provision of a pair of closures located inwardly of the transparent closures, and operable in a manner similar to said transparent closures whereby the lower closure contacts a portion of the upper closure, so that a continued lifting of the lower closure will likewise raise the upper closure to any desired open position.

Further objects are to provide a construction of maximum simplicity, efliciency, economy, and ease of assembly, operation and maintenance;

and such further objects, advantages and capabilities as will later'more fully appear and are inherently possessed thereby.

The invention further resides in the combination, construction, andarrangements of parts illustrated "in the accompanying drawings, and 5 while there is showntherein a preferred embodiment it is to be understood that the same is susceptible of modification and change, and comprehends other details and constructions with-, out departing from the spirit of the invention.

In the drawings:

Fig. 1 is a view in side elevation of the outside of the frame;

Fig. 2 is a view in vertical cross section through the window frame.

Fig. 3 is an enlarged fragmentary view in hori-- zontal cross section of the frame and slidable closures therein, the view being enlarged to-more clearly bring out the details of construction.

Fig. 4 is an enlarged fragmentary view in vertical cross section through the window construction taken on ,the line 4-4 of Fig. l.

Fig. 5 is an enlarged view in perspective of the details of construction of the inner sash member and the latch mechanism for locking the same in adjusted position.

Referring more particularly to the disclosure in the drawings, the embodiment selected to 11- lustrate the invention comprises a window frame I adapted to seat within and be connected to the side walls 2 of a structure, these side walls being provided with an opening for the reception of the window frame.

In the window frame are provided

slidable sash members

3 and 4 along with slidable louvers 5 and 6. The window frame is shown as provided with a sill 1 connected to the side walls by means of a metal trim 8, a head jamb 9 and side jambs I connected to the side walls 2 by means of metal trim I2. 7

A head plate I3 also forms part of the window frame construction and is connected to a metal trim M which in turn is connected to the side walls 2 of the structure. Although no particular attaching means are disclosed for connecting the various parts of the window frame to the walls, and the metal trim to these various parts, it .is to be understood that any suitable means such .as welding, bolting, or riveting may be employed for connecting the various parts together to form a unitary construction. The invention comprehends a unit construction which may be assembled at the factory and shipped for installation. 7 This head platel3 bridges across and connects 1 the side jambs l0, and at its lower edge is provided with a channel shaped portion II adapted to receive a part of the upper sash 2 when the same is in closed position.

Referring more particularly to the disclosure of the sash members, these

sash members

2 and 4 are of substantially the same construction and each comprises an upper pane seating section or rail l6, side rafls II, the upper sash being provided with a lower pane seating section or rail it, while the lower sash is provided with a lower pane seating section or rail it, each provided with a shoulder portion 20 adapted to support a pane of glass 11 embedded in suitable retaining and weathering material such as putty or the like and retained in place by glass retaining strips or members 2| which are suitably secured to the glass seating members or rails by bolts or other retaining means. v

The upper and lower glass seating members or rails l6 and it are each provided with longitudinally extending flanges or ribs 22, those of the upper sash 2 and the upper glam seating member or rail it of the sash 4 are similar in construction and are provided with a channelshaped interlocking portion 23 forming meeting rails and having a rearwardiy or inwardly projecting flange or rib 24 adapted to form a weather-tight closure when the sash members are in closed position.

The channel shaped portions 23 have embedded therein weathering material 25 such as felt or the like, the flanges or ribs 24 on the meeting rails provided on the base or lower part of the sash I and the top or upper portion of the cash 4, interengaging to provide a weather-tight closure when the sash members are in closed position. The flange or rib 24 on the meeting rail of the top or upper portion of the sash 3, is adapted to seat within the channel l5 intermediate a flange or rib 26 provided on the head plate l2, and the side wall thereof so that when the upper sash is in lowered position, these interengaging parts provide a weather-tight seal.

The lower pane-seating section I! on the sash 4 is likewise provided with longitudinally extending ribs or flanges 22, but these ribs or flanges are adapted to receive and retain a weather-strip 21 adapted to seat against and form a weather-tight closure with the sill when this lower sash is in closed position. In order to retain the weatherstripping 25, the flanges- 24 and 26 are all inwardly or rearwardly formed or undercut so as to retain the material without any auxiliary holding means. The weather-stripping 21 is retained by suitable holding means such as a screw 28 or the like.

In order to permit sliding movement of the

sash members

3 and 4, the side jambs iii are each provided with stiles 29, each stile member being of integral construction and retained by retaining

strips

30 and 3| suitably attached to the jambs.

The stile members 29 are bent to form channel-shaped portions provided with 'flanges 33 having inwardly extending projections 34 forming an integral weather-stripping and adapted to receive therebetween the flanges or ribs 22 on the side rails or pane seating sections I! of the sash members. By reason of the inwardly formed projections 34 provided on the flanges, a weathertight sealing engagement is secured between these members so as to provide a weather-proof construction. If desired, any suitable auxiliary weathering means may be employed in the channels formed in the stiles. Each stile member 29 aosm'n is formed with a lateral projection ll, the lateral projection of the outer stile members seating beneath and retained by a. strip 2|, while the inner stile members are retained by a common retaining strip or channel member 2| which likewise forms a spacing member for the upper and lower sash. These strips 20 and II are provided with upstanding ribs or stops 24 adapted to seat against the outer flanges 22 of the stiles and prevent displacement thereof and damage thereto.

In order to permit proper adjustment of the lower sash to its full height and then of the lower and upper sash, this lower sash member is provided with a latch 31 having a stationary handle 38 and an adjustable handle 39 adapted to operate a latch member or bolt (not shown) in its seating engagement with a rack 40 having oifset teeth 4|. As disclosed in Figs. 3 and 4, this rack is mounted between the stiles and may extend for the full height of the window frame.

From the disclosure it will be seen that the lower sash member 4 is made adjustable and may be adjusted throughout the height of the window frame. However when this sash member has been raised to a position equal to the height of the sash 2, the meeting rail member at the top of the sash member 4 will abut a stop plate 42 formed on or connected to the top of the upper sash 2, and thus any further lifting or raising of the lower sash will also raise the upper sash whereby the sash members may be elevated as a unit.-

In order to permit ready opening of the window, the upper window is connected to weights 43' attached to a cord orv chain 43" operating over a pulley 43 mounted on the jambs ll. Although the pulley is shown in connection with the upper sash it is to beunderstood that either or both of the sashes may be weight-hung.

In the present embodiment of the invention, one of the stop members 42 is mounted at each side of the upper sash and is provided with a resilient insert 44 such as rubber or the like which is adapted to be contacted by the lower sash member.

The louvers or closures 5 and 4 are also adapted to be raised into the well 45 provided in the top of the frame for the 'reception of the sash and louver members. Each of the louvers is constructed with T-shaped rafls 46 forming the top, bottom and sides of the louver construction. Each of these rails is provided with an undercut slot or groove 41. In the lower rail of the upper louver and in the upper and lower rails of the lower louver, this slot or groove is provided with an insert 48.

In order to permit sliding movement of these louvers, the jambs ID are provided with an oflset portion or shoulder 48, a bar 50, and a separating bar 5| adapted to be mounted in the lamb members by any suitable means, the separating bar Ii providing an abutment and separating means between the louver members 5 and 6. Intermediate the shoulder 49 and the separating bar SI and this separating bar and the bar 50 are thus provided channels or grooves forming a track for the louver members to slide.

A plate 52 is attached to the upper rail 46 of the upper louver to provide an abutment for the top rail 46 of the lower louver so that this lower louver may impinge against and raise the upper louver when desired. Each louver is provided with a plurality of ventilating openings 53 which are preferably staggered so as to keep out the weather. Although the weight-hung feature is 15 only disclosed in connection with the sash members it is to be understood that the louvers may likewise be so constructed.

From the above description and disclosure, it will-be readily seen that the invention comprehends a novel window construction including the details of the sash and louver members as well as weathering features in which the weathering means forms a part of the permanent window construction. However, as the strips 30 and SI are readily detachable, the resilient stile members may be quickly removed and replaced. v

The entire window construction may be assembled at the factory and may then be mounted as an assembly in a building construction. The parts may be made of any gauge metal as desired, merely depending upon the use to which the same is to be placed. When closed, the structure provides an efllcient weather-tight assembly.

Having thus disclosed the invention, I claim:

1. In a window construction, a frame therefor, stiles provided on the opposite sides of said frame and formed with channels, a sash slidable in said stiles and provided with projections adapted to seat in and be guided in said channels, latching means on said sash, and a rack bar for said latchmeans on the top rails of the upper sash and louver adapted to be contacted by the lower sash and louver when the latter are raised into open position whereby to raise said upper and lower sashes and louvers as a unit. a
