in for the purpose of sash l2.

illustration, there is disclosed a preferred embodiment of the present invention, the numeral It represents a substantially rectangular main window casing having the upper half of the opening therein closed by an upper 'Ihelower half of the opening in the window casing Ill is closed by a bottom sash Hi.

The bottom sash I4 is composed of an auxiliary window casing I '6 having vertical side pieces or rails l8 whose lower ends extend below the lower horizontal rail 20 of th casing Hi. The bottom sash also includes a. plurality of window frames or closure members 22, 24, 26 and 28.

Anchor plates 30 are secured to the lower horizontal edges of the frames 22, 24, 26, 28 and support vertical pivots or trunnions 32 that are located intermediate the vertical side edges of the respective frames on which they are mounted.

Additional trunnions or pivots (not shown) depend from the upper rail of the casing l6 and enter recesses (not shown) in the upper horizontal edges of the frames 22, 24, 26 and 28.

The trunnions 32 depending from the lower horizontal edges of the window frames extend through and below the rail 20 and include reduced externally threaded ends 34 that enter longitudinally spaced slots 36 provided in an actuating member or bar 38. An arm 40 is mounted on the end 34 of each trunnion 32 for rotation with the trunnions and these arms project laterally from the trunnions and are located beneath the rail 26.

Pit-mans or links 42 are terminally pivoted to the I armsfifi and the actuating member 38 so that, asthe actuating member i moved longitudinally all.

of the. window frames will r t e or swing about their vertical axes.

The arms 40 are secured to the trunnions depending from the lower edges of the frames by any suitable means such as nuts 43 threaded on the ends 34, and washers or spacers it received on the ends 34 space the arms 40 from the links 62, the link 42 from the member 38 and nuts 46 threaded on the ends 34 from the member 38.

Means is provided for moving the member 38 longitudinally to selectively open or close the win- This means consists of a channel bracket 48 mounted on the lower edge of the rail 20 that functions as a guide since it slidably receives the member 38. An operating shaft 58 is journaled for rotation in registering openings in the leg portions of th bracket 18 and supports a gear 52.

A portion 54 of the member 38 is ofiset and is provided with a plurality of spaced parallel, transversely extending slots or recesses 56 for selective- 1y receiving the teeth of the gear 52. The web of the bracket 48 is reinforced and strengthened by an anchor plate 58. A suitable hand grip 60 is secured on the shaft 50 to permit the shaft to be manually rotated.

Spring weather strips 62 are mounted on the upper edge of the rail 20 and the lower edge of the upper rail of the casing l6, and these strips are biased between the upper and lower rails and the frames 22, 24, 26, 28 to yieldingly retain the frames in a selected opened position and to close the spaces between the upper and lower rails and the upper and lower edges of the frames. A resilient closure or concealing strip 64 is mounted on the outer edges and between the lower ends of the side pieces l8 and also on the rail 20 and the inner edges of the side pieces are joined by a window casing C to conceal the actuating memher, the gear, the arms and the link. The lower rounded or flared edge 66 ofthe strip 64 will yieldingly bear against the window sill 68.

The outer side edges or vertical edges of the frames 22 and 28 are rabbeted to interlock with the rabbeted side pieces I8 of the casing I8. The inner vertical edge of the frame 22 is provided with a vertical rib or tongue in for entering a vertical groove or recess I2 in one vertical edge of the frame 24. The inner vertical edge of the frame 28 is provided with a vertical groove or recess 14 for receiving a vertical rib or tongue 16 on one vertical edge of the frame 25 so that the frames 22 and 24 will be sealed together and so that the frames 26 and 28 will also be sealed together when the frames are closed.

The adjacent vertical edges of the frames 24 and 26 are provided with a vertical rib or tongue 18 and a vertical groove or recess 80 respectively. When the frames are closed, the tongue 18 will enter the groove 80 to seal the frames 24 and 26.

Additional weather stripping may be used between adjacent frames and the frames and the casing H in order to prevent cold air passing through the window structure when the frames are in their closed position.

It should be noted that the arms 40 and the links 42 are so arranged as to permit all of the window frames to swing to an open position as the bar 38 is moved to the right, as shown in Figure 5, and to their closed position as the bar 38, in Figure 5, is moved to the left.

In practical use of the present invention, as the shaft 50 is rotated to move the bar 38 to the right, the links 42 associated with the trunnions on the frames 22 and 26 will pull the arms 40 associated with the sashes 22 and 24 to urge the frames 22 and 28 to an open position, and at the same time the links 42 associated with the trunnions for the frames 24 and 28 will push the arms 49 associated with the frames 24 and 28 to urge the frames 24 and 28 to an open position. The opposite procedure is followed when the bar 38 is moved to the left with the links 42 associated with the frames 22 and 26 pushing the arms 40 associated with the frames 22 and 26 and with links 42 associated with the frames 24 and 28 pulling the arms 40 associated wth the frames 24 and 28.

In view of the foregoing description taken in conjunction with the accompanying drawings it ing an opening therein, pairs of vertically rotating window frames mounted on said casing for closing the opening, said frames each having a vertical trunnion extending through the casing,

an actuating member concealed beneath the easing and having a group of longitudinally spaced slots therein slidably receiving the trunnions, mean forsupporting said member on said trunnions, means connecting the member to the trunnions to impart rotation to the trunnions and hence the frame during sliding of the member, and means mounted on the casing for sliding the member, said connecting means including an arm fixedly mounted on and projecting laterally from the trunnion of each frame and pitmans, each of which is terminally pivoted to said member and each of said arms.

2. A window structure comprising a window casing including a lower horizontal rail, an inner pair of horizontally swingable rigid window frames mounted on said casing, an outer pair of horizontally swingable rigid window frames also mounted on said casing, a trunnion securedto and depending from each of said frames, said trunnions extending downwardly through said lower rail, an elongated actuating member underlying said lower rail, means carried by the trunnions slidably supporting the actuating member, a guide supported on said lower rail slidably receiving said member, said member in cluding a plurality of longitudinally spaced slots receiving the lower ends of said trunnions, a horizontally extending arm fixed to the lower end of each of said trunnions, links each of which is pivoted to each of said arms and said member, a handle rotatably supported on said guide, a gear on said handle, and said member having an offset portion including a series of transversely extending parallel slots selectively meshing with said gear.
