The invention relates to a new and improved window having pivotally mounted tracks for guiding the upper and lower sashes, said sashes being removable from their guiding means when said tracks are swung out of the plane of the frame.

One object of the invention is to provide a window of the class set forth which may be constructed with fewer parts and hence at considerably less expense than the conventional window, the simplified and cheapened structure however, being nevertheless greatly advantageous.

A further object of the invention is to provide resilient means which performs the two-fold function of holding the sashes in adjusted position when slid along the tracks, and pressing said tracks against the stiles of the window frame, with sufficient friction to hold said tracks when they are swung about their pivots.

Another object is to provide novel releasable means for normally holding the sash-guiding tracks in vertical position.

Yet another aim is to provide for quick and easy detachment of the sash-guiding tracks when the window frame is to be painted.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a vertical sectional view with the sashes removed, the sash-guiding tracks being shown in vertical position in full lines and swung inwardly in dotted lines.

Fig. 2 is a View similar to Fig. 1 but showing the sashes and illustrating the lower sash partly raised.

Figs. 3 and 4 are detail horizontal sectional views on lines 3-3 and 4-4 of Fig. 2.

Fig. 5 is a detail vertical section on line 5-5 of Fig. 2.

Fig. 6 is an enlarged detail View showing the pivotal mounting for one of the upper sash-guiding tracks.

Fig. 7 is a View similar to Fig. 6 but showing the manner of detaching or attaching the sashguiding track with respect to the pivot.

Fig. 8 is a detail horizontal section on line 8--8 of Fig. 6.

Figs. 9 and 10 are edge views of two different forms of sash-holding springs.

In the drawings above briefly described, the numeral 10 denotes a window frame whose stiles 1l are provided with flat parallel inner sides, said Stiles being secured in any suitable way to a header 12 and a sill 13.

Two sash-guiding tracks 14 lie against the lat inner sides or" the stiles 11 and extend throughout the lengths of the upper halves of said stiles. rwo similaisash-guiding tracks 14=L lie against the inner sides of the stiles 11 and extend 60 throughout the lengths or' the lower halves of said Stiles, the meeting ends of the two sets of tracks being beveled as denoted at 15. The upper ends of the upper tracks 14 are pivoted at 16 to the stiles 11, and the lower ends of the lower tracks 14a are similarly pivoted at 16a to said stiles.

An upper sash 17 is slidably engaged with the upper tracks 14, and a lower sash 17a is similarly engaged with the tracks 14a, and the adjacent ends of these sashes overlap in the usual manner and may be locked together by a conventional sash fastener. To hold the sashes 17 and 11a in adjusted position and to frictionally hold the tracks 14 against the inner sides of the stiles 11, I provide any desired number of springs which exert an inward pressure on the sashes and an outward pressure on said tracks. In the present showing, two bowed springs 18 are spot-welded at 19 to the inner sides of the tracks 14, and two additional springs 18CL are welded at 19a to the inner sides of the tracks 14a. These springs bear frictionally against the vertical edges of the sashes and thus serve to hold the latter when they are slid to any desired position. Then too, when tracks and sashes are swung inwardly about the pivots 16 and 16a, the springs 1S and 18ad press said tracks against the stiles 11 with sufficient friction to hold said tracks in the positions to which they have been swung. When either sash and the associated tracks are inwardly swung, the sash may be entirely removed from engagement with said tracks for quick and easy cleaning, and said sash may be easily re-engaged with said tracks. The swinging and sliding of the sashes is also of advantage for Ventilating purposes.

Each of the tracks 14 and 14a is preferably formed from a single vertically elongated strip either stamped or cast to provide it with parallel sash guides, the guides of the upper strip being denoted at 20 and 20', and those of the lower strip at 2l and 21. The outer edges of the tracks or strips 14 and 14a preferably abut shoulders 22 on the stiles 11, when in Vertical position. At this time, the upper ends of the tracks 14 preferably abut the header 10 and the lower ends of the tracks 14a similarly abut the sill 13.

In order to prevent the tracks 14 and 14e from dragging excessively upon the inner sides of the stiles 11 when they are swung about their pivots, I preferably inset wear plates 23 in said stiles, the track-engaging faces of said plates being a few thousandths of an inch inward of the inner sides of said stiles. Both of these wear plates carry upper and lower spring tongues 24 and 25 stamped therefrom to hold the tracks 14 and 14a normally in vertical position by abutting the inner edges of said tracks. Pressing the tongues outwardly, releases the tracks for inward swinging.

To limit the swinging of the tracks 14 and 14, under ordinary circumstances, I preferably provide them with arcuate slots 26 and 26CL which are concentric with the pivots 16 and 16a respectively, said slots receiving stops 27 and 27at carried by the stiles 11. When the sashes are slid from the tracks however, the latter may be sprung free of the stops 27 and 2'7a and then swung to horizontal positions, and the pivots 16 and 16a are so constructed as to then allow detachment of the tracks to give access to the frame stiles for painting. In `forming each of these pivots, a short corrugated tube 29 is driven tightly into an opening in the frame stile, said tube having an elongated head 30 on its outer end, passable through a slot 31 in the sash-guiding track and normally extending across said slot. Sufficient swinging of. the track however, so aligns the head and slot as to allow each detachment or attachment of said track.

In Fig. 9, I illustrate a slightly different spring 28 which may be used in place of the springs 18 and 18a. Also in Fig. 10, I illustrate a third type of spring having two bowed portions 28a, this type being particularly adaptable to use with heavy sashes.

It will be seen from the foregoing that novel and advantageous provision has been made for carrying out the objects of the invention, and while the structure shown is preferably followed, variations may, of course, be made within the scope of the invention as claimed.
