This invention relates to improvements in metal windows and has reference more particularly to an improved storm window sash frame.

The use of metal windows in buildings of all kinds, including residences, is quite common and is increasing. It is often desirable, especially where the winters are cold, to employ double or storm windows as this results in a substantial saving of fuel.

It is the object of this invention to produce a storm window that can be used to replace the screen and which is applied to the window on the inside.

A further object is to produce an improved structural sash member and a rubber seal strip cooperating therewith lto effect an airtight seal.

The above and any other objects that may become apparent as the description proceeds are attained by means of a construction and arrangement of parts that will now be described in detail, reference for which purpose will be had to the accompanying drawing in which the invention has been illustrated and in which:

Figure 1 is an elevational view showing the inside of a metal window provided with the improved storm window;

Figure 2 is a section taken on line 2 2, Figure 1;

Figure 3 is a fragmentary section taken on line 3 3, Figure 1;

Figure 4 is a. section taken on line 4 4, Figure l showing the Ventilating section in closed position;

Figure 5 is a view, partly in section and partly in elevation, showing the sash frame and the rubber seal strip in assembled relation; and

Figure 6 is a cross section of the seal strip.

In the drawing reference numeral I designates the wall of a building, which has been shown as of concrete but which may be of brick or any other similar construction. Numeral II designates the window frame with which window l2 is associated. Window I2 is hinged at I3 and is shown in closed position, the open position being indicated by broken lines. No novelty is claimed for parts I I, I2 and I3 as they are shown in the same relation in U. S. Patent 2,203,172.

The storm window to which this invention relates comprises a rectangular sash having vertical and horizontal members I-4 of the cross sectional shape shown in Figures 2, 3 and 5. The space enclosed by the sash frame is divided into two parts by a transverse bar I5. The part above bar I is closed by a glass pane I6 and the opening below cross piece I5 is closed by a door comprising a frame formed from horizontal bottom and top members I1 and I8 and vertical side members I9. A glass pane 20 closes the opening in said frame.

Referring now more particularly to Figure 3 which shows a cross section of the storm window sash to substantially full size it will be observed that member I4 is formed from two elongated rectangular parts A and B whose longer sides are positioned in parallel planes. Rectangulars A and B are offset as shown and are joined along their adjacent corner edges by a connecting portion C. The free narrow or inner edge of rectangle A has a groove 26 for pivot pins 28 on the bottom side I9 of the door. Rectangle B has its wider side facing away from rectangle A, provided wth a T-slot 2l for the head 23 of the flat strip 22 whose shoulders 24 engage underneath the flanges 25 as shown. The sash frame whose cross sectional shape has been described is secured to window frame II by means of spring clips 2l held in place by screws in the manner shown in Figure 2.

The Ventilating opening below bar I5, formed by sash frame I4 is closed by a door comprising the frame whose sides have been designated by numerals I1, I8 and I9 and a glass plate 2b for winter or a screen for summer. Side I1 has pivot pins 28 that project into channels 26. 'The door is held in closed position by a latch like that illustrated in Figure 4 comprising a spring pressed plunger 29 and a knob 30.

The cross sectional shape of sash frame member I4 is of great importance and value in the relationship shown.

The Ventilating opening, located below bar I5, is closed by the glass door 20 comprising members I1, I8, I9 and 20, Bar I'I at the bottom of glass 20 is provided with two or more pins 28 that extend into groove 26 and hold the door in position. Bar I8 is provided with a spring pressed plunger 29 (see Figure 4) that serves to latch the door in closed position. A knob 30 serves as a handle for opening and closing the door.

It will be observed from Figs. 2 and 3 that the Ventilating door is held in place by pivot pins 28 that extends into groove 26 at a point as near as practical to the bottom of the glass, and by the spring pressed plunger.

The structural shape shown in Figures 3 and 5 in combination with the seal strip is an important feature of this invention and the examiners attention is directed in particular thereto.

Having described the invention what I claim as new 1s:

A window sash frame of extruded aluminum having a cross section comprising two rectanguiar channel shaped members having their bases at right angles to one another, the open side of one of the channel members facing the inner periphery of the frame, the open side of the other channel member facing the Wall of the building with which the frame is to be used, the latter channel member having its flanges inturned suiciently to partially close its open side, the second member being offset in the direction of its open side from the rst member an amount at least 'as great vas the Width of the .rst member, the second member being outward of but adjacent the periphery of the frame portion formed by the first member, and a web connecting only` References Cited in the le of this patent Number UNITED STATES PATENTS Name Date Palenske et al.
