' Referringitmtheedrawingst:llfiindicates oneiofa pairrof-ssheetzrmetalzside railseorrj ambss" ofr come cnossesectional-i configuration, each blind stop 2 thereofmAs illustrated in- Figures v and 6, each side rail or jamb is of stepped form in cross-section to provide a pair of guide ways,

relatively off-set from one another in two directions. Each rail embodiesa flange 3, as a base therefor longitudinally of and for the full length of the rail for overlapping .the outer surface or edge of the outer blind stop2 of the window frame for application thereon. The flange may be provided with suitably spaced aper,-.

ion to the base flange 3 of each of the side rails and in plane therewith. v

The web portion II of the cross rail I0, extends in a horizontal plane from the window frame and covers the stepped upper end of side rails and the outer flange depending therefrom overlaps the outer face of the transverse end limb or riser of the step 5, of the side rails I. The opposite ends of the Web portion H, are bent laterally to provide depending lips or tangs I2, which respectively overlap the upper end' of the stepd of the side rails. The opposite longitudinal tures or notches opening to the outer edge, each for the reception of a screw or other type of fastening means for attaching the rails to the blind stop The flange isof; appropriate width to accommodate for an absoluteperpendicular setting of the rail irrespective of any degree that the jamb of thewindow frame may be out of plumb and to sustain the auxiliary sash-inward from the jambs of the window frame. From the fiange, the rail is bent laterally from one side thereof to provide a pair of right" angular relatively stepped portions or steps 4 and 5, for thefull length of the rail and which extend outward when the rail is installed uponthe window frame. The crosssectional configuration of the side rails therefore provide a pair of off-set ways or steps, for sustaining relatively difierential widths of sash and screen panels-withthe innermost-way or step for the greater width of sash'within the minimum width dimension of the window frame to allow ample clearance-for a direct inner removal of the auxiliary sash and screen panels without being required to cant the same for passage through the window frame. :This also provides ample marginalspace forpanel clamping or looking devices with which-"theside rails or parts may be equipped. The stepped form of side rails materially 'stiffens and reinforces the rail structure so that they can be constructed of comparatively thin gauge metal; aswell as simplifying its production. Y

The outer step 5, of the side rails, serves for sustaining an uppersash 6, and a lower screen panel 1,. .in relative alignment, Eachis independently locked or confined to the rails so that they can be separately removed without disturbance one to the other. The screen panel can therefore be removed. and omitted during the winter season, if desired, and alternately a screen panel can be interchanged with the upper sash 6, during the summer season, if it is desired to screen the full openingarea of the window. 7 The upper auxiliary sash or panel 6, at its opposite lowercorners respectively, is seated and laterally confined by a stationary latch 8, fixed to a sid rail, which requires that the panel be slightly elevated for release therefrom for panel removal. The screen panel is shown for release therefrom for panel removal. The screen panel is shown as locked in place, by a pair of. spring bolts 9, each respectively traversing an aperture in a side rail. The forms of latch or locking means disclosed is merely selective it being obvious that various othertypes may be employed.

The upper end of the side rails I,"join with and are capped by ahead rail III of Z-bar form in cross section and maybe described as comprising a web portionIl, having laterally projecting flange respectively from each of its longitudinal ends, extendinginrelative opposite directions. .One of the'fiangesserves as a base for securing'the rail'to the upper-outer crossblind stopof the window frame and therefore companends of the head rail completely covers and sheds the upper ends of the side rails and the construction is such that the rails need not be fastened together, which is of advantage in the application thereof to the window frame. medial portion of the depending flange of the head rail for its length between the longitudinal ends of the side rails is depressed to bring the same into registry and alignment or plane with the outer head of the step 5,- of the side rails for a bearing contact with the upper rail of the frame of the upper sash 6. A length of flexible metal weather strip I3, of angle form in cross section is fixed to the lower or inner side of the web II of the cross rail, to overlap the inner side of the upper end of the sash frame, to laterally confine the same and yieldingly bind the sash against the depending flange of the cross rail I0 and side rails I.

The head rail with the weather stripping provides a channel for the full width of the upper panel and has a depth to permit the upper panel to beelevated from the latches 8, and above the top of the lower panel I4, whereupon the upper panel can be swung to an angle inwardly of the window frame, the weather stripping yielding sufficiently, so that the panel can be slid or conveyed downwardly for removal.

The sash and screen panel are'equipped with means for obtaining a hand hold thereon, a type for each is illustrated respectively in Figures 8 and 9, to facilitate in the manual handling of the panels for insertion and removal, and which will,

hereinafter, be described in detail.

As illustrated in Figure 7, the lower end of the screen panel I, is confined against lateral displacement b a pair of stationary latches I5, I 5, each respectively fixed to a relative side rail. Upon releasing the spring bolts 9, from their locking connection with the side rails the panel can be tilted to a degree sufficient to clear the lower end of the upper panel, and thereupon it can be elevated to a degree to release it from the lower latches I5, I5, whence it can be wi.hdrawn inwardly of the window frame for removal.

The lower auxiliary glazed .panel I4, is slidably sustained within guideways or channels formed by the step 4, of the side rails and an angle strip l6, respectively fixed to the limb or riser of the inner step of each rail extending perpendicular or at an angle to the fiange 3, thereof. The channels thus formed for each of the side rails correspondingly are slightly short of the length of the lower sash to permit the panel to be extracted therefrom in an elevated position.

'Guidingly and laterally confining the lower panel within the side rails provides for elevating the same to any partial height within the channel for a ventilation adjustment and it is locked in any ventilating position of adjustment by a clamp lever I1, pivotally mounted or journalled within a supporting plate I8, fixed to the face side of the angle strip I6. The forward or stud when the lever is-moved to extendin an angular position from the channel, impingingly bears against the side rail of the lower panel frame securely binds the same in its adjusted elevated position.

The upper cross rail of the frame ofthe lower panel, at its outer side, carries a yielding weather or sealing strip IQ, for a bearing contact with the lower rail of the frame of the upper panel 6, when both panels are in their closed position, as illustrated in Figure 2. The sealingor weather strip [9, is produced from a thin gauge sheet metal material, spring tempered, bent to U-form in cross section, with one limb thereof serving for anchoring the strip within the channel of cross rail of the panel frame, formed of a channel bar, the end of the limb having a lateral flange longitudinally thereof to bear against the inner side of the web of the frame bar or base of the channel-thereof and overlie the edge of the glass pane glazed within the frame. The weather strip is inserted within the panel frame preliminary to glazing, so that the pane and putty or medium securing the pane within the panel frame anchor the weather strip to the frame without the use of any auxiliary fastening means. This method ofapplication of the wea-her strip to the frame is simple, efficient, economical and devoid of any air gaps. The yielding limb if the weather strip flares rearwardly over the edge surface of the rail of the panel frame, which serves to reinforce the limb longitudinally to avoid against crimping which would result in the production of air gaps and interfere within a uniform bearing contact with the adjoining surface of the lower rail of the upper panel against which the limb bears in the closed position of both upper and lower panels.

The method of application of the weather stripping to the sash or panel frame is analogously followed for the application hook sash lifts or handles-20, to the panel frames as illustrated in Figures 2 and 8, and for a handle 2|, to the frame of the screen panel, as shown in Figure 9.

It is more preferable to apply the handles to the side rails of the screen frame, and as the screen fabric and the means for securing the same marginally within a channel in the frame rails, are of a yielding character and to appropriately direct the hand gripping portion of the handle inwardl from the frame, it is of angle form in cross section, with the anchoring flange or limb 22, thereof of U-form in cross section to clasp about a flange of a rail bar of the screen frame. The handle at the corner formed by the angular form of the plate is corrugated to loop about the outer side corner of the rail of the screen frame and in conjunction with the anchoring flange, secures the handle to the rail against lateral displacement and non-disturbing to. the screen fabric and beading or binding strip ,clinching the screen fabric within the channel of the frame.

The frame forming rails for both sash and screen frames are of conventional form, preferably producedfrom extruded metal bars as of aluminum or non-corroding metal alloy, of .extreme stability and lightness in. weight with the bar thickness of both sash and screen framesof the same dimension. lhis provides for registry of the frames of the upper sash and lower screen and which also permit ready interchange of a screen panel for the upper sash for a seasonal changej As the depth measurementof eachltypa of panel is approximately three-eighths Qf-Jan: inch, theyprovide for a, minimum depth of side, and top cross rails which can be. confinedwithin.

the. window'frame. for architectural design.

The siderails and head or top rail: for sym metry, approximate the same width dimension. allowing for an: excessive degree. of elevation for: theupper panel than nominally required for its remova1,. which is of material advantage presfabrication and application of the unit to an in-:

stalled window frame, in eliminating undue fits tingaccuracy in making. the application. .Ordinarilyzit is only necessary to. trim the upperend. of theaside rails to, accommodatefor anxapeu propriate. application; of the rails withinv the? window frame. andiwhich permits the. fixtures upon the rails to. be pre.applied.. Thisumate rially reducesthe time, labor and cost .ofinstal'e. lation and permits standardizingwthe sizes: oftha sash and screen panels.

In. producing the: rails l, by aniextrudedl metal. process, the limbs of the steps on, theirv inner. side, may each be. provided. with" a. rib.23,l ere tending longitudinally thereof, as shown in we 10, which materially strengthens therail and; provides for a minimum bearing contact with the rail, reducing friction in, the sliding movement of the sash. The rib on the riser, portion .or limb of the step provides a shoulder for, latch:
