Application April27, 1950, Serial No. 158,505

This invention relates to storm sash particularly adapted for use with windows of the double hung type, and in particular this invention relates to a comparatively thin frame in which upper and lower sash are slid-ably and removably mounted and in which a screen frame is removably positioned in the channel below the upper sash.

The purpose of this invention is to provide storm sash having a comparatively thin frame that is positioned between the outside stop and and outer face of the frame of a window and that is provided with upper and lower siding sash and ascreen frame so that the window may be opened similar to a double hung window.

This invention is an improvement over my copending application for a combination storm sash and screen filed June 2, 1949, with the Serial Number 96,667, now abandoned, wherein the sash and wire holding frames are formed to provide sockets for the glass and wire whereby the thickness of the holding frame is reduced.

Various types of storm sash have been provided and metal windows have been provided with upper and lower sash of the double hung type but it has been found difficult to combine these elements in a storm sash in which a screen may also be incorporated and that is sufficiently thin to be installed in the outer edge of a window frame.

The object of this invention is, therefore, to provide means for forming glass and wire screen holding frames whereby sliding frames for glass and wire mesh are mounted in a thin channel shaped frame.

Another object of the invention is to provide a combination storm sash and screen having upper and lower sash in which the upper and lower sash and screen are readily removable from the mounting frame.

A further object of the invention is to provide an improved combination storm sash and screen in which the width thereof permits the sash to be installed in a frame beyond the outside stop and which is of a simple and economical construction.

With these and other objects and. advantages in view the invention embodies a rectangular shape mounting frame channel shape in crosssection having vertically disposed sides and an upper end,

3 Claims. (Cl. 160-90) upper and lower sash slidably mounted in the frame, a screen frame with wire mesh therein removably mounted in the outer part of the frame, resilient means retaining the sash and frame-and handles slidably mounted inone side of each of the frames for gripping the frames to compress the resilient means for removing the frames from themounting frame.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved combination storm sash and screen of this invention includes an upper outer sash having a frame It), a lower inner sash having a similar frame I l, a screen formed with wire mesh 12 held in a frame l3, and a mounting frame formedwith side channels I4 and I5 and an upper connecting channel [6.

The upper and lower sash, as indicated by the screen frame against one side of the mounting 5s numerals l0 and H are formed, as shown with continuous structural shapes bent at right angles at the corners with the side flanges mortised and glass panels I! and I8 are mounted in the frames thereof. The frame of the upper outer sash I is provided with a cross plate having an outer flange or plate I9 and an inner flange or plate and the plate 20 is bent inwardly forming a flange 2| the inner edge of which extends at right angles to form a flange or cross flange 22 and the end of the plate 22 is provided with a lip 23 against which the edge of the glass l'l rests. The outer flange iii is bent to slope inwardly to frictionally grip and form a. seal with the glass, the flange being sprung outwardly as the glass is forced into the frame. With the sides and ends of the sash frames formed in this manner the glass panels l1 4 By this means the sash or screen is drawn toward the opposite side of the mounting frame whereby the springs 42 are compressed and with the frames held in this position they are free to pass outwardly of the storm sash with the edges thereof passing over the edge of the flange on the side member M of the frame. The screen frame [3 is formed with a continuous rectangular shaped section with the sides formed to provide an inner flange 55 which provides a continuous groove 56 in which the edges of the wire mesh I2 are secured by channel shaped flllers as indicated. by

and I8 are frictionally and rigidly held at both sides and also at the upper and lower ends whereby each frame with its glass panel forms a complete unit.

A sealing strip 24 of felt or the like is secured against the outer surface of the upper horizontal member of the lower sash frame and also on the outer surface of the side members of the frame whereby with the lower horizontal member of .sides.

;.:The sash frames are slidably mounted in an outer mounting frame having channel-shaped side sections with outer inwardly inclined flanges 2 5 and 26 and inner flanges 21 and 23, the flanges 25 and 21 being connected by a web forming a back 29 and the flanges 26 and 28 by a web forming a back es. The upper ends of the side members are connected by a channel-shaped cross member having an outer flange 3i and an inner inwardly inclined flange 32 with the flanges connected by a web 33. The lower edge ofthe inner flange 32 is provided with an inwardly extended tip 34 providing a springy action whereby the upper member of the sash frame is resiliently held against the outer flange 3|.

The'upper horizontally disposed member of the mounting frame is secured to the side members is and i5 by triangular shaped caps 35 as illustratedin Figure 8, the caps having vertical sec- ,tions 36 and horizontal sections 3'! with the edges of the vertical and horizontal sections connected by triangular shaped webs 38. '1.

The side member in is provided with a channel shaped filler having a web 39 with flanges 4i) and 4! and, as illustrated in Figure 3 the sides of the sash frame slide against the outer surfaces of the webs 39 with the frames held between the flanges 25 and 21 at one side and 26 and 28 at the other.

The frames of the upper and lower sash l0 and .l i are provided, at the opposite side with springs 32 having hook-like clips 43 and 44 on the ends and the clips extend through openings 45 and 46 in the sections 2| of the frames whereby the sash frames and screen are resiliently urged against 1 the surface of the channel shaped filler 39 on the opposite side of the mounting frame. "Theframes are also provided with handles 47 that are slidably mounted in openings 48 and 49 in base plates 5e and the base plates are secured tothe sections 2! of the frame by screws 5! and 52. The U-shaped handles 41 are provided with enlarged ends 53 and 54 by which they are reta ined in'the openings l tl and 49 of the plate 50.

the numeral 57. With the edges of the wire mesh positioned over the groove 56 in the sides and ends of the frame the members 51 are forced into the grooves to clamp the edges of the screen in posi- 7 tion.

I the outer sides of the frame and these indentations provide projections that engage the lower edges of the blocks 58 and retain the blocks in position.

With the parts arranged in this manner the outer mounting frame is secured against the outer surfaces of the outside stops of a window frame and with these parts in place the upper and lower sash and screen frame are installed.

The sash and screen frames are inserted by pressing the edges containing the springs 42 into the opposite sides of the frame whereby with the springs compressed at one side with the parts as illustrated in Figure 4 the opposite sides of the frame are readily removed over the extending flanges 25 so that the edges of the frames are free to snap into grooves or openings behind the flanges. V i

A channel shaped base member having a back (H with flanges 62 and 63 at the sides is mounted on the sill 54 of thewindow frame 65 and this channel is positioned to receive the lower edge of the lower horizontal rail or cross member of the lower sash frame H, as shown in Figure 2. By this means the lower edge of the storm sash is sealed and the lower rail or member of the screen frame rests directly upon the upper surface of the window sill with the inner surface positioned against the flange 52 of the channel shaped base member.

The upper and lower sash are; free to slide upwardly and downwardly in the frame with the screen frame removed and the screen frame [3 is removably mounted below the lower end of the upper sash I0 whereby the upper sash frame l0 and the screen may remain in position permanently and the inner or lower sash frame II is free to be actuated upwardly or downwardlyas may be desired. The inner or lower sash frame l I is resiliently held by the springs 42 in elevated positions in the frame. i

It will be understood that other modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.
