B. J. BOWL-ER WINDOW SCREEN Filed April 18. 1923 Patented Mar. 31 1925.

UNITED STATES BRADLEY J. BOWLER, or BALTIMORE, MARYLAND.

WINDOW SCREEN.

Application filed April 18, 1923. Serial No. 632,957.

To all whom it may concern Be it known that I, BRADLEY J. Bowman, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Window Screens, of which the following is a specification.

This invention relates to improvements in window screens, and has for its object to provide a sliding screen that can be applied to any window without the necessity of providing the window frame with additional strips of similar devices for the screen to slide upon, as is customary with the screens now in use.

The invention consists of the novel construction and arrangements of the parts and combination of parts hereinafter more fully set forth in the following specification and pointed out in detail in the appended claims.

In the accompanying drawings,

Figure 1 is an elevation of the lower portion of the window frame and sash, and showing my invention applied thereto.

Figure 2 is a section of Figure 1 taken on the line 8-8.

Figure 3 is an enlarged detail of the screen.

Figure 4 is a section of Figure 3 taken on the line 99.

Figure 5 is an enlarged detail perspective view of one of the upper stationary guides.

Figure 6 is an enlarged detail perspective view of the stationary lower guide.

Figure 7 is an enlarged detail perspective view of the pivoted lower guide.

Referring to the accompanying drawing, forming part of this specification and in which like reference numerals designate like parts throughout the several views thereof, 1 designates the window sash having the usual beads 2 and 3 on opposite sides thereof between the lower sash l slides. The screen is formed, in the present instance, of two frames 5, 5 secured together with a suit" able wire mesh netting 6 held therebetween. At the upper end of the screen and projecting from each side thereof, is a guide 7 each having angle ends 8 and held between the frames 5, 5 by screws or nails passing through the holes 9. The lower end of the screen is provided at one end with a stationary guide 10 having one end held between the frames 5, 5 by screws or nails passing through the holes 11, and the opposite side is provided with a pivoted guide 12 pivoted at its inner end at 13 and having a hole let for the reception of a screw or pin 15 to hold the pivoted guide in position when the screen is in use. The outer ends of said guides 10 and 12 are approximately U-shaped and fit over and slide upon the beads 2 on opposite sides of the frame 1.

Wl 1en the screen is to be placed in position in the window frame, the guide 12 is dropped down in the position shown in dotted lines in Figure 3 of the drawing. The

upper end of the screen is then placed above.

the lower sash slightly tilted and then turned down and lowered slightly to allow the guides 7 to come in between the upper end of the lower sash 4 and the head 2. The screen is then given a slight spring to allow the stationary guide 10 at the lower end to sprlng over the bead 2, the screen is then raised slightly to allow the pivoted guide 12 to be raised in position where it is held by the pin 15. The screen can be raised or lowered at will with the upper guides 7 slidlng between the lower sash and the bead 2 and the lower guides sliding on the beads 2.

It will be seen from the foregoing that my invention can be applied to any window without the use of an additional strips of appllances whatever being applied to the window frame or sash.

It will also be seen that both the lower guides may be pivoted if desired.

Having thus described my invention, what I claim is:

1. A window screen comprising two frames secured together, a wire mesh secured between said two frames, stationary guides at its upper end and each having one end secured between said frames and its opposite end projecting "from said frames, two pivoted guides on the lower end of said frames each having one end pivoted between said frames and its free end being approximately U-shaped and adapted to fit over and slide upon the beads of the window frame.

2. The combination with a window frame and a window sash having beads on opposite sides thereof, of a screen slidable between said beads and having guides at its upper end projecting from each side thereof and extending between the window sash and said heads, a stationary guide on the lower end of the screen at one side thereof and having its free end approximately U- shaped and adapted to fit over and slide upon one of the beads of the Window frame, and a pivoted guide at the opposite lower end of said frame having its free end ap proximately U-shaped and adapted to fit over and slide upon the head on the opposite side of the Window frame.v 10

In testimony whereof I affix my signature.
