DODGE ET AL WINDOW SCREEN Filed March 51, 1927 2 Sheets-Sheet 2 Patented Oct. 29, 1929 UNITED STATES PATENT OFFICE ANDREW J. DODGE AND JOHN C. PETTIBONE, OF ANSONIA, CONNECTICUT WINDOW SCREEN This invention relates to window screens, and has for an object to provide an improved mounting for a screen, which when the window is closed will be wound up into a relatively, small space where it is out of the way and is protected against deterioration from the action of the elements or from other inur 1 1 It is also an object of the invention to provide a construction of this type in which the act of opening the window will bring the screen into position, and in which there is locking means for simultaneously clamping the window and screen in any desired posi- 115 tion. Y

It is a further object of the invention to provide a construction for thistype of screen in which there is an approved and convenient means for quickly attaching or detaching the screen to or from the sash, and in which the mounting for the screen may be easily removed for storing the screen or it may be as easily mounted in position.

With the foregoing and other objects in 2 5 view, wehave devised the construction illusformn these showing our improved screen in position, the

lower sash of the window being raised to open position.

Fig. 2 is a transverse vertical section thereof substantially on line 22 of Fig.1.

Fig. 3 is a horizontal section through the sash above the screen.

Fig. 4 is a vertical section through the upper supporting bar for the screen showing the clamping means in elevation. I

' Fig. 5 is a vertical section through the clamp operating means substantially on line 66 of Fig. 4, and Y Fig. 6 is a front elevation of the socket and the sash used to secure the top bar of the screen thereto.

The upper and lower sashes of the window are indicated at 10 and 11 respectively. and they are mounted to slide vertically in a frame 12 in the usual manner. The glass carried by the sash is indicated at 13. Our improved screen 14 is composed of the usual wire mesh which should, however, be preferably of relatively soft copper wire so as to be fairly flexible. It is connected at its lower end to a spring operated roller 15 and at its upper end is' detachably connected to the lower bar 16 of the lower sash. It may, of course, be used on the upper sash in the same manner if desired. The wire mesh 14 is attached'at its upper end to a horizontal bar 17, and means are provided for detachably connecting this bar to the lower bar 16 of the sash. For this purpose on the front of the bar 16 are mounted a pair of plates 18 having an elongated opening 19, the sash bar being recessed behind this opening. Mounted in the upper bar 17 of the screen is a pair of T- head bolts 20, these boltsextending through the'bar 17 and mounted for, turning movements-therein. The T-heads' 21 are on the rear of the bar and are adapted to pass through the elongated openings 19, and then if the bolt is turned ninety degrees the head will be transverse to this slot and will securely fasten the bar 17 to the bar 16 of the sash. 7 The bolt is easily manipulated by a small handle 22 at the front of the bar 17 and a knurled check nut 23 may be threaded on this bolt at the front of the bar, and when the bolt is turned to bring the head across the opening 19 this nut may be tightened to clamp the bolt in this position. Of course, when the T-head is brought to the upright position the bar .17 may be easily removed from the sash, thu's detaching the screenfrom the sash.

On the inner surface of the upright sides of the frame are mounted upright guides 24 for the upright edges of the'screen and also the locking or clamping means. These guides are preferably of sheet metal and are prefer- 199 ably of substantially the shape shown in Fig. 3, there being an open slot 25 in their inner 'walls for the screen and the clamping members. These guides hold the edges of the screen straight and prevent passage of insects past these edges, and also provide means to cooperate with the locking device.

The locking device is mounted in the horizontal bar 17. This bar is provided with a longitud na greova 26 the top wall in keyumayt beainsertedi humane front; The
