BY Mew- WW 5M Dec. 20, 1955 w. G. SMITH SEASONAL WINDOW STRUCTURE 4 Sheets-Sheet 4 Filed Sept. 15, 1952 w h "M Q m a. M m M Z m w United States Patent 2,727,596 SEASONAL WINDOW STRUCTURE William G. Smith, Scottsbluff, N ebr. Application September 15, 1952, Serial No. 309,684 4 Claims. (Cl. 189-75) This invention relates to new and useful improvements in window structures and the primary object of the present invention is to provide a seasonal window structure that may be installed within an existing window opening or placed within a window opening during wall construction of a building.

Another important object of the present invention is to provide a complete seasonal window structure unit that is readily adjustable to fit window frames whose stiles and rails are not perfectly straight.

A further object of the present invention is to provide a window structure composed of hollow vertical and horizontal portions that will define a continuous air chamber for insulation purposes.

Yet another feature of the present invention is to provide a seasonal window structure involving storm sash and/or screens that are quickly and readily removed from the inside of a building and which cannot be removed from the outside of a building, thereby providing a safe, anti-theft window structure whose screens and/or storm sash may be cleaned, repaired or inspected in a convenient manner.

A still further aim of the present invention is to provide a seasonal window structure that is simple and practical in construction, strong and reliable in use, compact in structure, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view of the invention installed in the window opening of a wall;

Figure 2 is a front elevational view of the invention with parts broken away and shown in section, and with dotted lines showing the frame enlarged;

Figure 3 is a longitudinal vertical sectional view taken substantially on the plane of section line 33 of Figure 2;

Figure 4 is an enlarged vertical sectional view taken substantially on the plane of section line 4-4 of Figure 2;

Figure 5 is an enlarged vertical sectional view taken substantially on the plane of section line 5-5 of Figure 2;

Figure 6 is a fragmentary perspective view of one upper corner of the present window structure;

Figure 7 is a fragmentary perspective view of one of the lower corners of the present window structure; and

Figure 8 is a fragmentary perspective view of one of the storm sashes used in the present invention.

Referring now to the drawings in detail, wherein, for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral 10 represents an open, substantially rectangular frame member including upper and lower channel-shaped rails 12 2,727,596 Patented Dec. 20, 1955 and 14 and a pair of channel- shaped stiles 16 and 18. The channel- shaped stiles 16 and 18 face outwardly and the channel shaped rail 12 faces upwardly as shown best in Figure 6.

The channel-shaped lower rail 14 faces upwardly and its vertical flanges 20 and 22 are provided with extensions. The extension of the flange 20 is bent to form a step 24 that terminates in a vertical flange 26 and the extension of the flange 22 inclines upwardly and outwardly, as at 28, and terminates in a downwardly facing, rib-forming channel 30 that receives and grips the flange 26, as shown in Figure 7.

The web portions of the stiles 16 and 18 are pressed outwardly to form vertical abutment and retainer ribs or flanges 32 that extend into the rectangular opening of the frame member 10. The upper rail 12 of the frame member 10 is also provided with a web portion that is pressed downwardly to form a horizontal rib or flange 34 whose inner face lies in a vertical plane with the inner faces of the flanges 32.

A mounting frame 36 is engaged with the frame member 10 and includes parts which are vertically and horizontally slidably engaged with frame member 10. Mounting frame 36 includes a downwardly facing channel-shaped rail or header 38 that is received over the rail 12. The inner wall 40 of the header 38 is provided with an inturned flange 42 that will engage the outwardly turned flange 44 on the inner wall 46 of the rail 12 to limit upward movement of the header 38 relative to the rail 12.

Mounting frame 36 also includes channel-shaped stiles or side members 48 that face each other to accommodate the stiles 16 and 18. The inner walls 50 of the side members 48 are provided with inturned flanges 52 that will engage the outwardly turned flanges 54 on the inner vertical walls 56 of the stiles 16 and 18 to limit outward horizontal sliding movement of the members 48 relative to the stiles 16 and 18.

The ends of the header 38 are slidably connected to the upper ends of the side members 48 by corner channels 58. These corner channels, 58, include vertical portions 60 in which the upper ends of the members 48 are slidably received and horizontal portions 62 in which the ends of the header 38 are received. A flange 64 on the inner wall of each horizontal portion 62 is engaged under the flange 42 and a flange 66 on the inner wall of each vertical portion 60 is engaged against the inturned flanges 52 of the side members 48.

The frame member 10 is capable of removably supporting upper and lower storm sashes 68 and 70. These sashes are similarly constructed and each includes a hollow rectangular frame portion 72 of extruded resilient metal that is bent to include a peripheral channel 74 which receives the peripheral edge 76 of a window pane 78. Openings, such as 80, are provided in the vertical parts of the frame portions 72 and the upper part of the upper sash 68 and yieldingly receive weather sealing strips 82 that will contact the ribs 32, 34.

A downwardly facing channel 84 is formed in the lower horizontal rail of the lower sash 70 and yieldingly receives a weather strip 85 having a groove 86 for accommodating the channel 38. A horizontal spring strip 88 is secured to the web portion of rail 12 and coacts with the rib 34 in yieldingly gripping the upper horizontal part of sash 68, as shown in Figure 4.

Horizontal guides 90 are fixed in the ends of channel 84 and slidably receive locking plungers 92 that are urged by springs 94 from the vertical parts of the sash 70 to each selected vertically spaced aperture'95 in webs 16. Finger grips 96 attached to the plungers 92 are slidably received in guide slots 98 in the inner wall of the lower horizontal part of sash 70. Finger loops 100 on the sash 70 form means for removing and replacing the lower window sash.

The frame member 10 is further capable of removably supporting a screen 102. The screen 102 comprises a substantially rectangular, open frame 104 whose peripheral flanges. 106 and 108 are bent inwardly one above the other to form retainer lips 110 and 112 that receive the edges of a foraminous member 114 therebetween. Fasteners 116 connect the lips 110 and 112 and clamp the same against the member 114.

The web portions of stiles 16 and 18 fixedly support ledge-forming hooks 118 upon which the lower corners .of the upper sash 68 rest when the latter is raised as shown in Figure 4. When the upper sash is removed (following removal of the lower sash), the upper sash is raised to clear the ledge-forming hooks 118 and then it is pulled toward the operatorand lowered.

Retainer guides 120 are attached to or formed with the webs of stiles 16 and 18 and extend inwardly on a plane with the inside vertical flanges of the stiles 16 and 18.

These retainer guides 120 aflord a positive guidance for the lower sash through an area that is otherwise inaccessible due to sashes of the inside window. The guides 120 extend downward just far enough to securely hold the top of the lower glass section 70, when the latter is in its closed position. The lower sash will, however, clear these strips when the lock p-lungers are released and as the sash is pulled forwardly and downwardly from under the guides.

Having described the invention, what is claimed as new is:
