The object of the'present invention is to i provide a window structure, preferably formed of rolled sheet metal elements, and in which. glass-carrying frames are employed mounted in the sashes and capable of lateral movement for the purpose of giving ventilation and also making the outer sides of the panes accessible within the room for the purpose of cleaning. A further and important object isto provide a structure of relatively simple character in which the glass-carryin frames will be maintained wherever place In the accompanying drawings Figure 1 is a perspective view of the preferred embodiment of the invention and showing the glass-carrying frames in various positions.

' Figures 3 and 4 are cross pivot and holding Figure 2 is a vertical sectional view through the window structure with the sashes and transom closed. V

Figure 5 is a perspective view of oneof the devices.

In the embodlment disclosed a window frame is provided that is refer-ably formed of sheet metal; and inclu es a sill member 6 having anupstanding abutment rib 7 for the lower sash. The sides of the frame are in the form of boxes 8, in which'the usual weights indicatedat 9 in Figure 3. reci rocate. The sides include plates 10 locate on' the inner sides of the boxes 8 and these plates ide slots 11. They arehave longitudinal furthermore provi ed with channeled members 12 that serve also as guides. Inthe present structure a tubular rail formed of sheet metal sections and designated 13 divides the 4 frame into an upper transom opening14 and a lowerwindow opening 15. A transom is shown at '16, saidtransom being pivoted at its lower end as illustrated at 17 wher'eby it may be swung inwardly. A latch 18 serves to hold. the transom in its closed position. In the window opening 15 are cooperatingvertically sliding sashes Hand 20. As these sashesare substantially alike in structure, a description of one it is believed be suflicientfor both, the material differences being later pointed out.

' lated to the sash frame that ures 3 and 4 that the outstandiii flanges 22 travel in the 'de channels 12. ixedto the outer sides 0 the body strips 21 of the stiles are angle bars or strips 24, the outstan flanges of which travel in the. guide slots 11 of t e plate 10. It will thus be evident that the sashes are guided vertically in the window frame. The bottom rail of the upper sash has its upstanding flange 22 inset at an in'clination, as shownv at 25, and the top rail of the lower sash has secured u on it a strip 26 provided with a downturned'mclined rtion 27 that overlies the portion 25. sashes are closed (see F re 2) turned flange 23 of the ttom. rail of the lower sash 20 depends over and alon do the upstanding portlon 7 of the sill 6.

angle bar.28 t at enters a groove 29 formed by the downturned terminal'flanges 30 of the main frame rail 13. Thus 'interfitting portions are provided between the two. sashes and between the two sashes and the window i frame, that serve to air and water.

- In each of the

sashes

19 and 20 is mounted a laterally movable glass-carrying frame, and as the frames in both instances are the same, a description of one will do for both. Each sash-carrying frame consists of substantially Z-shaped bars or strips comgrisi portion 31 with an outstan ing flange 32 along its inner edge and an inset flange 33 along its outer edge. The latter flange is bent prevent the entrance of receiving channel 35. The glass pane is shown an angle strip 37 placed behind t 0 las an secured to the body portion 31. t will be noted that the glass-carrying frame is so rethe former abut the flange 23 of the latter and that the flange 32 ofsaid lass-carryingframe abuts the flange 22 of t 0 each frame when inwardly as shown at'34 to provide a puttythe glass-carrying frame is in its closed position orfitted within the sash frame.

The glass-carrying frame has pivoted to its stiles and as shown at 38 the lower ends of .links 39, the pivots 38 being preferably'located below the centers of said stiles. The upper ends of the links 39 are pivoted to the inner sides of the upper ends of the sashcarrying frames, as shown at 40. The lower end of the glass-carrying frame has a sliding pivotal mounting in the sash frame. To this end there are secured to the inner sides of the lower portions of the stiles of said sash frames vertical channel bars 41. The lower rails of the glass-carrying frame have secured thereto angle bars 42 which form with the flanges 32 a channel 43. In this channel are secured spring-pressed plungers (see Figure 5 for the detail thereof). A U-shaped frame '44 is secured in the channel 43, thus providing spaced downturned ears 45.and in said ears is a reciprocatory plunger 46 having a cylindrical head 47 that engages in one of the guide channel bars 41. On the shank of the plunger 46 is acoiled spring 48 that abuts against the rear ear and against a shoulder 49 formed on the shank. .The spring thus urges the plunger outwardly and; causes the free end of its head to frictionally bear with considerable pressure against the bottom .of the channel 'guideway 41. There being two of these plungers, it will be evident that they project from the opposite lower corners of the sash-carrying frame and constitute not only pivots on which the said frame swings,-

but also act as sliding frictional bearing members in the sash frame. It will be noted by 1 referenceto Figure 2 that when the glasscarrying frame is in its closed position; the

lower flange 32 depends on the outer side of and against the upstanding flange 22 of the sash frame and that the depending flange 42 ofthe glass-carrying-frame depends on the outer side and against the flange 23 of the sash frame. A'tight joint is thus obtained. The upper end of the glass-carrying frame can be secured to the sash frame by any suitable means, as for instance a rotary latch 50 mounted on the upper end of the glass-carrying frame and having a nib 51 that inter-.

locks with the upperrail of the sash frame. A suitable detachable handle shown at 52 in Figure 1 can be used for turning this latch.

' With this construction, when the sash carrying frames are closed and locked. both upper and lower sashes may be raised or lowered in the usual manner. If it is desired to open either or both of the windows for ventilating purposes and without raising the sashes, it is only necessarv to unlock and draw the glass-carryingframes inwardlv'. This causes the upper ends of said frames to swing inwardly, while the lower rails turn on the pivot axes of the heads 37 and thus the

flanges

22 and 23 and rise above the same. The glass-carrying frames can be positioned as desired and as indicated in Figure 1, their positions being maintained by the spring plungers frictionally engaging the bottoms of the channel pieces 41 and holding the'frames against accidental movement.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in \the art without

flanges

32 and 42 will swing away from the further description and it will be understood rying frame, guideway on the "stiles of the sashframe, and spring-pressed plungers located longitudinally of and housed in the ends of the channel of said channeled rail of the glass-carrying frame and slidablyextending through the open end of the channel and engaged in the guideways of the sash frames stiles.

' 2. In a window structure, the combination with a sash frame including a rail having spaced flanges, of a glass-carrying frame including a rail having spaced flanges that slidably overlap the flanges of the sash rail, said flanges of the rail of the glass-carrying frame forming an openended channel between them, links pivoted to the sash frame and to the glass-carrying frame, guideways on the .st'iles of the vsash frame and springpressed plungers located longitudinally of and housed in the channel of said rail of the glass-carrying frame and having their ends extending through the open ends of the channel and slidably engaged in the guideways of the sash frames stiles.

3. In a window structure, the combination with a window frame, of a sash frame ,slidouter sides of the flanges of the said sash frame rail, links pivoted to the upper por tions of the stiles of the sash frame-and to intermediateportions of the stiles of the glass-carrying frame, and spring-pressed plungers located longitudinally of and in the channel of the rail of the glass-carrying frame and projecting into and frictionally engaging the guide channels ofthe stiles of J the sash frame.

4. In a window structure, the combination with a sash frame having a stile provided with an inset outer flange and a gnideway behind the flange, a glass carrying frame having a stile that abuts against the flange and having an inner outstanding flange that abuts the sash stile, forming a boxing for the guideway, said sash carrying frame having achanneled cross rail, and a spring pressed plunger located longitudinally of and housed in the channel of the rail and having a head slidable in the guideway of the sash stile.

5. In a window structure, the combination with a sash frame having a stile provided with an inset outer flange and a longitudinal gnideway behind the flange at one end of the stile, a glass carrying frame having a stile that abuts against the flange and having an inner outstanding flange that abuts the sash stile forming a boxing for the guideway, a link pivoted to both stiles at one end of the guideway and enclosed by the flanges of the stiles, said sash carrying frame having an open-ended channeled rail, and a .30 spring-pressed plunger housed in the channel of the rail and having a head extended through the open end and slidable in the guideway of the sash stile.
