Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed January 25, 1912. Serial No. 673,387.

To all whom it may concern y Be it known that I, MORTON G. BUNNELL, aqcitizen of the United States of America,

and'resident of Chicago, Cook-county, Illinois, have invented a certain new and useful Improvement in iVmdow-S'creens, of

which the followingis a specification.

' My invention relates to automatic window screens of that kind in which the wire cloth the screen being automatically brought into use each time the window is opened by raising orlowering the sash, it being understood that a screen of this kind can be used at either the top or the bottom of the window. i The object of my invention is to provide novel and effective means for removably securing the edge of the screen to the window sash, whereby the window can be opened without operating the screen, as will here inafter more fully appear.

To this and other useful ends, my invention consists in matters hereinafter set forth and claimed. V

In the accompanying drawingsFigure 1 is a front elevation of a window with the lower sash thereof partially open. Fig. 2 is an enlarged cross section through the lower portion of the sash on line 22 in Fig. 1; Fig. 3 is a front elevation of a portion of the mechanism. Fig. a is a perspective of a fragment of the lower portion of the sash.

As thus illustrated, my invention comprises a screen A attached to the lower'sash B of a window ofany suitable form or character. The lower edge of this screen, which is made of wire cloth, is secured to a roller (not shown) in the box a which sets in the window frame below the sash. The side edges of the screen travel up and down in the'guides a at the sides of the window frame. As the said roll and guides are not a part of the present improvement, no further explanation thereof is necessary.

The screen A has. its upper edge provided with a metal binding a in the form of a strip of sheet .metal folded to receive and hold the upper edge portion of the screen. This metal binding strip a is provided at intervals with openings a which engage the heads. of screws a? inserted in the sash These screw heads serve also to hold a strip of felt a or similar material, upon the face of the sasln A metal strip a is held in place on the sash by screwsa, whereby the strip a is further clamped and held in place. The metal binding strip a? bears against the cloth strip a below the clamping strip a to make a tight joint. The locking levers a are'pivoted on the strip a by rivets a and are provided with portions (2- which move over the binding strip a to holdthe latter in place on the sash. These levers have their upper'ends connected by a rod a and the middle lever has a handle a, wherebythe operatlon of one lever serves to operate them all in unison. When the levers are disengaged from the strip a the screen can then be disengaged from the sash, and the latter can then be opened and closed without operating the automatic screen. The sash isprovided with'the usual handles a by which it is raised and lowered.

From the foregoing it will be seen that by my invention I provide an automatic window screen that can be readily'connected with and disconnected from the sash. The mechanism by which the screen is locked to the sash is controlled by the single handle a in the manner shown and described. In this way the screen can be quickly brought into use, and when not needed is easily disconnected to leave the sash free to open and closeindependently. Also, this makes it possible to readily disconnect the screen in cleaning the window. 7
