To all whom it may concern:

Be it known that I, JAMES WV. TOOHEY,

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.

One object of the invention is to provide an improved construction of screen-frame whereby thesame may be readily adjusted to fit the window opening.

Another object is to provide an improved adjustable screen-frame to enable the screenfabric to be readily attached thereto without the aid of tools so that renewal of the fabric when necessary, may be accomplished with ease.

A further object is to provide an improved screen that may be quickly attached to or detached from the window and which will effect a close joint with the bottom rail of the window and thus prevent the entrance of insects, and another object is to provide an improved construction of ad justable screen whereby the fabric may be -maintained in-a stretched condition when in use and which may be quickly detached and rolled up in a small roll for convenience in storage.

With these and other objects in view the accompanying drawings illustrate the invention, wherein.

Figure 1, shows a front elevation of a window-frame and the lower portion of the raised lower sash to which the improved screen is attached. Figs. 2 and 3 are perspective views respectively of the upper and lower adjustable screen bars. Fig. 4 is a vertical sectional elevation, on an enlarged, scale, of the upper and lower screen bars with the screen fabric secured therein and also shows the means employed for securing the screen to the frame and the relative po sitions of the screen and window sash,the section being taken on the line H of Fig. 1. Fig. 5 shows a vertical cross-section through the upper screen bars and the screen-fabric secured therein -this section being taken on the line 5 5 of Fig. 1 but the bars being shown in a spread condition to better illustrate the construction. Fig. 6, is a similar section, but through the lower screen bar and the section being taken on the line 6-6 of Fig. 1. Fig. 7 shows a horibe explained.

zontal or longitudinai cross-section through the upper screen-bar,-the section being taken on the line 7-97 of Fig. 4, and Fig. 8, shows a similar view through the lower screen-barthe section. being taken on the line 8-8 of Fig. 4:. I

In the drawing the numeral 1 designates the sill of the window-frame; 2 rho vertical side members thereof; 3 the usual guide strips and 4 the lower sash which is held in the frame by the guide strips. The sash has the usual bottom and top rails 5 and 6 respectively and the side rails 7 that connect te said bottom and top rails whereby to form the sash frame. The screen employs upper and lower adiustable bars 8 and 9 respectively to which the upper and lower edges of the wire fabric 10 are secured. The

upper bar 8 of the screen comprises two sections 11 and 12 which cooperate as best seen in Fig. 2 of the drawing wherein the sections are viewed from the outer side or from the side reverse to that shown in Fig. 1. The section 11 is slightly smaller than section 12 otherwise the two sections are substantially alike in construction. fore to Figs. 2 and 4 it will be seen that the sections are formed of sheet metal each hav-.

ing a front wall 13 with an upturned flange 141 at the inner and lower horizontal edge and a clamping wall 15 extending downwardly from the upper horizontal edge of the said front wall 131 An upwardly-extending inclined flange 16 carried from the lower edge of the clamping wall 15the object and function of which will presently be explained. In the present instance the flange 1G is of less length than the length of the clamping wall 15 and front wall 13 thus providing a notch or cut-out 17 at the extreme outer ends of the sections for a purpose also presently to The upper edge of flange 16 on the section 11 is provided with a down turned hook 18 so that the two sections may be t-elescoped and the edge 19 of flange 16 on section 12 may pass beneath and be held by the hook on the flange 16 of section 11.

The outer end of the walls 13 and 15 of sections 11 and 12 each have registering eyes 20 and one end of a spiral spring 31 passed through said eyes whereby to hoid the spring thereto.

It will be noted by reference to Fig. 12, that when the sections 11 and 1 2 of the top screen bar are telescopically engaged the By reference there flange 14 on section 11 enters in the flange 14 on section 12 receives the edge 19 of section 12.

The lower screen bar 9 is also formed of two sheet- metal sections 21 and 22 both of which have an intermediate longitudinal bend or fold 23 which forms front and rear walls 24 and 25 respectively. The front wall 24 has a down-turned flange 26 along its upper rear edge and the rear wall 25 has a down-turned flange 27 along its upper rear edge. The outer ends of walls 24: and 25 of lower screen bar sections. 21 and 22 have registering slots 28-- the slots being located 5 immediately above the longitudinal bend or fold 23 and below the lower edges of downturned flanges 26 and 27. i

In assemblingthe screen the lower sash 4 is first raised to its limit. The wirefabric is then cut slightly longer than the distance from the sill to the bottom rail of the raised sash. Ifthe width of the wire fabric is the same as the width of the window opening to be covered no manipulation of the side edges of'the fabric will be necessary, but if the fa ie is wider than the opening, then a fold will be formed on said side edges of the wire fabric to enable it to snugly fit between the vertical portions 2 of the frame. This fold may readily be formed by utilizing one of the sections as a straight edge by laying the same on the wire fabric and turn ing the latter back over the edge of said section. After the proper width of wire fabric has been provided the next operation is to form an open hook at the upper and lower horizontal edges of the wire fabric,the

hooks on these opposite edges being turned so as to lie adjacent to that surface of the wire fabric that is to form the inner surface when the screen is in use. The hook on the upper edge will be turned downwardly and that on the lower edge will project upwardly. The next step may be the attachment of the upper screen-bar in which case the up turned flange 14 of section 11 will be telescoped with the down t-urned hook29 on the upper edge of the fabric. This operation will take place from one side edge of the wire fabric and thesection 11 will be moved along the hook. until its outc' becomes flush with the vertical side edge of the fabric. The section 12 will then be telescopically engaged with the same hook 29 but from the opposite vertical side edge of the wire fabric, and when the inner end of this section 12 reaches the inner end of the previously positioned section 11 the flange 14 on section 12 will pass over the flange 14 on section 11 and at the same time the hook 18 on section 1 1 will pass over the edge 19 of section 12, thus telescoping the inner ends .of the two sections. The movement of section 12 onto section 11 will continue until the outer end of section 12 beend . screen bar 9 as follows:

comes [lush with the vertical side edge of but that hook 18 on section 11 i the wire fabric, whereupon if desired, the lip-turned flange 14 and the clamping wall 15 may be squeezed or mashed together, as shown in Fig. 4 and the hook 29 at .the upper edge of the wire fabric will thus be secured in place. The lower edge of the wire fabric may then be secured in the lower- The hook 30 which turns upwardly will be telescopically engaged with the down turned flanges 26 on the sections 21 and 22 and the inner ends of said sections will-be telescopically engaged. with said hook 30 of the wire between them, as seen in Figs. 4 and 6. The walls 24 and 25 of these lower bar sections may then be pressed sufficiently close together to. hold the wire cloth, and the screen will then be in condition for attachment to the window. It will be seen that the op erations pf assembling the screen are-simple and such as most any one of'ordinary intelligence can perform. The next and final operation is to properly attach the screen with respect to the sash and window.

By reference to Figs. 1 and 4 it will be seen that each guide strip 3 at the sides of the side rails 7 of the sash carriesa hook 32 and that the upper ends of the spiral springs 31 have eyes 33 that engage the hooks 32 and thus'enabl'e the upper screen bar to be sustained from said hooks. At the sill 1 I provide hooks 34.and these latter hooks are so positioned that they may be made to pro ject through the slots 28 in the ends of the lower screen-bar sections and thus hold said sections down close against the sill.

When the screen is in position in-a window opening the lower bar thereof will be rigidly held by the hooks 34 while the upper bar will be yieldingly sustained from the hooks 32 by the springs 31. These springs maintain a constant pull on the screen and keep the latter in a uniformly stretched condition.

' By providing the notches 17 at the ends of the upper screen-bar sections the latter will seat against the guide strips 3 and the inclined flange 16. will project between the two guide strips and seat against the bottom rail 5 of the sash thus effectually closing the space that would otherwise be present between said window rail and top bar.

It is obvious that the screen may be readily removed by simply drawing the lower bar away from the lower hooks 3st and then disengaging the springs from the hooks 32.

lower rail of a window sash when the latter is raised; a sheet of wire fabric having its opposite side edges free and its upper edge secured to the two telescoping upper bar sections in front of the inclined flanges on the latter and the lower edge of the said fabric being secured to the two telescoping lower bar sections; and means for yieldingly stretching the wire fabric by drawing on one set of said telescoping bars whereby to tilt the inclined flange on the telescoping upper bar sections against the rail of the window sash.

2. In a window screen the combination with a sheet of wire fabric, of telescoping lower bar sections at the lower edge of the wire fabric; telescoping upper bar sections at the upper edge of said fabric and each of said upper bar sections being disconnected from the lower bar sections and the outer ends of said upper and lower bar sections each having a perforation; yielding means engaging the perforations in the outer ends of the upper bar sections; means for secur ing the yielding means with respect to the frame of a window and means for engaging the perforations in the outer ends of the lower bar sections to detachably hold the said lower bar sections with respect to the frame. v

3. In a window screen the combination with a sheet of wire fabric having a loose down-turned fold at its upper edge and a loose up-turned told at its lower edge; an upper bar having an up-turned flange with which the down-turned fold of the wire fabric eItgages and also having a Wall to clamp the fabric against said up-turned flange; a lower bar having a down-turned flange to engage the up-turned fold at th. lower edge of the wire fabric; means for yieldingly sustaining the upper bar and means'for securing the lower bar.

4. In a window screen the combination with asheet of wire fabric, of telesco ing upper bar sections at the upper edge 0 the fabric and each of said sections having an inclined flange projecting at one side that is shorter than the bar proper whereby to leave a notch at the outer ends of the sections; a lower telescoping bar section at the lower edge of the wire fabric and spiral springs attached to the upper bar sections between their outer ends and the ends of the inclined flange.

In testimony whereof I allix my signature in presence of two witnesses.
