body providing the grooves 2I for the stiles is formed to provide a shoulder 22 against which is seated the frame 23 of the screen I9. Drain openings 88 are formed through each tongue 25 and flange 21 at each end thereof.

The under surfaces of the top rail I3 and of the intermediate rails I4 are covered with a sheet metal support 28 which is formed to provide a plurality of spaced channelways 29 therein in which are slidably received the upper edges of the sashes I5, I6, I! and Hi. In like manner, the outer edge portion of the support 28 is formed to provide a channelway 30 to receive the upper edge of the screen frame 23. Referring specifically to Figures 1 and 2, it is noted that each channelway 29 is formed with a keeper portion 3i which includes a depending abutment or floor 32 which substantially abuts the upper edges of the sashes I5, I6, I! and I8, whereby to prevent vertical movement of the sashes while permitting lateral sliding movement thereof. The channelways 29 also include a release portion 33 laterally of the keeper portion 3I, in which release portion the sashes are vertically movable, whereby to disengage the lower edges thereof from the tongues 25.

A look shaft 35 extends through each top rail I3 and intermediate rail I4 in the region of the ,channelways 29. Each shaft 35 is provided with an integral radially-extending key 36 which normally extends into each release portion 33 to lie substantially flush with the abutment 32, whereby to normally prevent vertical movement of the sash positioned in a release portion. Each shaft 35 extends across the channelway 30 for the screen and is likewise provided with a key 38 which normally extends into the channelway 33 to prevent vertical movement of the screen therein. The inner end of the shaft 35 is provided with a handle 31 of any suitable form to permit pivoting of th shaft whereby to move the keys 36 and 38 out of the release portions 33 of the channelways 29 and 30, whereby to permit ver tical movement of the sashes positioned in such release portions, and vertical movement of the screen. As is clearly shown in Figure 7, upon vertical movement of a sash into the release portion 33, the lower grooved edge 44 thereof will clear the related tongue 25, whereby the sash is swingable inwardly to the broken line position, and then downwardly to remove the same from the window frame. The lower rear portion of .the screen I9 is formed to provide a pair of depending keepers or flanges 40 which extend over the vertical flange 21 f the lower body of sheet metal 26. Handle members M are provided for the screen I9, whereby upon retraction of the key 38 from the channelway 30, the screen may be lifted upwardly and swung inwardly or outwardly to clear the flange 21, and thus permit removal of the screen.

Referring specifically to Figure 4 and Figure 5, it is noted that the handle 31 for the shaft 35 is adapted to pass over the hooked end 42 of the leaf spring 43, whereby to lock the handle 3'! in at least a position wherein the keys 36 and 38 are advanced so as to lock the sashes and screen in place. The hooked end 42 of the spring 43 is depressible manually to permit the handle to be swung to a position to retract the keys 36 and 38.

As is shown in Figure 6, the lower edges of the sashes I5, I6, I! and I8 are formed with grooves 44 to slidably fit atop the tongues 25. Obviously, this structure could be reversed and the tongues 25 could be placed on the sashes with the grooves 4 44 in the upper surfaces of the sill and intermediate rails.

Referring specifically to Figures 2 and 3, it is noted that weather blocks 50 are provided at intermediate portions of the sill II and intermediate rails I4 on the upper surfaces thereof between the adjacent pairs of tongues 25. The e blocks are adapted to underlie the abutting edges of the sashes I5 and I6 and IT and I8 to prevent cold air from entering through the window. In like manner, the opposite portions of the sheet metal bodies 28 on the under surface of the top rail I3 and intermediate rails I4 are formed to provide depending weather blocks 52 between each pair of trackways 29. Such weather blocks 52 overlie the upper side surfaces of the sashes to prevent cold air from entering the house.

Referring specifically to Figure 3, the abutting vertical edges of each pair of sashes I", I6 and I1, I8 are formed to provide weather guards 68 and BI. Each of such weather guards comprises a resilient strip of sheet metal which is reversely bent at an angle to overlie the inner or outer face of the related sash. The guards 68 and GI are complementary to each other, whereby when the sashes are in the closed position, as shown in Figure 3, the weather guard 63 of the sash I5 or I! will overlap the rearwardly-directed weather guard SI of the forward sash IE or IS. The guards 66 and 6| are preferably formed with alignable apertures 63 therethrough for the reception of a locking bolt 64. The bolt 64 is formed with an annular groove 65 therein intermediate its ends, and is slidable in a bushing 66 carried by the innermost frame of sash I5 or II. The outermost frame of sash I6 or I8 is preferably formed with a recess 61 to receive the free end of the bolt 64. The bushing 66 is formed with a leaf spring 68 which extends through a slot formed in the bushing 66 to engage the groove 35 with the bolt, whereby to hold the latter in a retracted position. Obviously, though not shown, a second groove, such as that at 65, could be provided on the bolt 64 to retain the same in a locked position. Instead, I have provided a slot III in the bolt which is engaged by the spring 68 to lock the same in the advanced or locking position. Obviously, with the bolt in the full line position, Figure 3, the sashes I5 and I5 are locked against sliding or vertical movement. In like manner, when the bolt 64 is moved to the broken line position, the sashes may be freely slid and/0r removed.

While I have shown and described what is now thought to be the preferred embodiment of my invention, it is to be understood that the same is susceptible of other forms and expressions. Consequently, I do not limit myself to the precise structure shown and described hereinabove, except as hereinafter claimed.

I claim:
