The invention relates to window screens, and has for its object to provide upper and lower overlapping screens disposed in a window frame and adapted for vertical movement therein.

A further object is to provide a window screen comprised of upper and lower overlapping screens both removably disposed in a window frame, and adapted for vertical movement therein, the upper screen being held in position by spring means carried by said window frame, said spring means also being adapted to hold the lower screen when in raised position.

A further object is to provide a window screen comprised of upper and lower slidable screens disposedin a window frame, said window frame having channeled portions formed to guide and retain the upper screen bycon- 29 tact with resilient gripping members, and

the channeled portions being open on one side for a portion of their length, whereby both screens may be easily and quickly applied or removed from the window frame from within the building With the above the other objects in View,

the invention resides in the particular com bination and arrangement- 0f parts as hereinafter set forth, shown in the drawing, de- 3 scribed and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the of the window frame,- and has it s upperend spirit of the invention.' In the drawings:

Figure 1 is a view 1n elevation of the screen as installed in the window frame.

Figure 2 is a. vertical sectional view taken on line 22 of Figure 1.

Figure 3 is a vertical sectional view taken on line 2-2 of Figure lshowing the lower screen in raised position.

Figure 4 is a fragmentary. view in elevation ofthe window frame showing the sprin member.

Referring to the drawing, the numeral 1.

designates a window frame of the conventional type, having stilesQ, upper rail 8 and sill 4. Carried by the window frame at .the

frame guide members 5 and the stiles 2 to form a channel 7 at the upper part of the inner side of each stile. p 7

Disposed in the Window frame. andin the channel? are an upper screen 8' and av lower to screen 19, which overlap at their meeting The screens are preferably formed with metal frames, but any suitable frame may be used". The upper screen '8 is disposed almost entirely within the channels 7 andis held imposition-[by contact at their upper ends with the spring membersv 10,

which are preferably leaf springs, but may be of any type. suitable for the, purpose,- The springmembers 10 are disposed in the channelsg7 and preferably secured. to; theopposite vertical frame guidemembers 5 at the upper ends thereof. The spring'members 10 extend outwardly in naturalposi-tion and almost touch the guide members 6. The upper 7 screen 8 is placed thech-annels 7 in aposition to touch the ;-rail 3 of the window frame, and'when in that position. the springs lOg-te-ncl to push the upper end of the screen 8, outwardly againstv the guide Inembers 6, and in that manner frictionallyhold it in its, proper position. I I I H Thelower screen 9 rests, upon the sill. 4

the upper screen 8. Theflower end of-the lowerscreen 9,-is. disposed between thelo wer horizontal frame guide member .5 and the WQfClly in the. window frame-and fromfalling out ofthe. frame. The frame of the low- .er screen 9-also carries afhandleme nber 12 5 v byv which the screen may be raise d and lowered.

It. be seen from the above that normal, closed position the upper screen'S is diseased in the nnels '71 and is'th'ere held 39,

by the springs 10 which press the screen one flange of each guide terminating short of against th guide emb 6; d th low the bottom of said guide, whereby the screens screen 9 rests on the sill 4; between the frame y be removed r m ud guldesguide members 5 and the stops 11, and has its upper end overlapping the lower end of the screen 8 in the channels 7. WVhen it is desired to raise the lower screen it may be done by pushing it up in the channels 7 and when it is so raised it will remain in the position in which it is placed. In raising the lower screen the springs 10 are further depressed by the screen 8 against which the raised lower screen 9 pushes in being raised, as shown in Figure 3, and consequently the spring pushes outwardly against the screen 8 and through it against the screen 9 which is consequently firmly wedged and held between the screen 8 and the guide members 6, and may thus be held in any position to which it may be raised.

It will also be seen that the screens may easily be removed from and installed in the window frame. The lower screen 9 may be removed by lifting it above the stops 11, pushing its lower end outwardly clear of the sill and then pulling its upper end down free from the channels 7. The upper screen may then be readily removed by pulling it down out of engagement with the springslO and then clear of the channels7. i

I It will thus be obvious from the foregoing that the improvement contemplates an exceedingly simple structure, whence the screens may be easily and quickly installed or removed from within the building, the advantages of which are apparent, especially with respect to screened windows on upper floors.

The invention having been set forth, what is claimed as new and useful is:

1. In a Window screen device, screen receiving members, upper and lower screens slidably disposed in said members, and means carried by and cooperating with said screen guide members, upper and lower screens slidably disposed in said guide members and adapted for vertical movement therein, and a spring member carried by each guide me1nber at the upper end thereof, said spring members forming means for holding the upper screen in operatlve pos1t1on and for holding said lower screen in raised POSltlOIl,

In testimony whereof I affix my signature.

LEE C. STEELE.
