Application filed February 1;,"1923. sw rm. 618,497.

To all whom it may concern! Be it known that I,"WILLIAMI LATHRorn WVRIGHT, a citizen of the United States, re

siding at Kansas City, in the county of Jackson and State of Missouri, have'invented certain new and useful Improvements in Window Screens, ofwhich the following is a specification.

Myinvention relates toan all-metal window screen and one objectis to provide a durable frame for screens. of this character which is fireproof and will outlast the ordinary wooden frame usually employed in the lengths and can be quickly installed for use, or removed when it is desired to wash the windows.

Another object is to provide a frame of such cross sectional-configuration and provided with retaining elements whereby the wire screen can be drawn taut and firmly held in place, or quickly removed when worn out and replaced by another. I

Other objects will hereinafter appear,and in order that the invention may be fully understood, reference will now be had to the accompanying drawing, in, which:

Fig. 1 is a broken front elevation of a window with the screen in position therein.

Fig. 2 is an enlarged detail perspective view of one of the elbows and a portion of one of the strips which connect said elbows.

Fig. 3 is a detail perspective view of a retaining strip, a plurality of which areemployed in holding the wire screen in the frame.

Fig. 4 is an enlarged cross section of the frame and the screen on line IV of Fig. 1.

Fig. 5 is-a fragmentary side elevation 0f the screen frame in positlon 1n the window frame. 1

Referring now 1n detail to the various parts, A designates thB'WIIIClOWV frame, B

the upper window sash, and C the vertical stops which coact with other stops usually employed in holding the upper sash B in place in the frame A.

Referring now more particularly to the 1 screen frame constituting an important feat me of the invention, 2, designates a lurality of sheet metal elbows, one of w eh is employed at each corner of'the frame-as disclosed by Fig. 1. The-intermediate front portion 4 of each elbow 2 projects outwardly and has an abrupt longitudinal portion 6 and an oblique angular longitudinal portion 8, which reinforce the elbow and assist in firmly holding the wire screen .30 in position as Will hereinafter appear. tudinalmargins 10 of the elbows 2' turn in wardly' towards'each other to assist in hold ing-side and end sheet metal strips 12 and 14 in assembled relation with said elbows.

The strips 12 and 14 are of substantially the same cross sectional configuration as the elbows 2, excepting that their margins 16 are not turned toward each other like the margins 10. The strips 12 and 14 slidably engage the elbows 2, so that theframe may be adjusted longitudinally and transversely to fit window frames of different lengths and widths. After being adjusted in the elbows 2, the strips 12 and 14 are firmly locked in position by bolts 18 and 20 extending throughholes22 in the elbows and longitudinal slots 24 and 26 in the strips 12 and 14, respectively.

28 designates retaining strips one of which is associated with each strip 12 and 14. The retaining strips 28 are of substantially the same cross sectional configuration as the strips 12 and 14 in order to snugly fit therein and firmlyhold the wire screen 30 in place as shown more clearly by Fig. 4. Each re- The longltaining strip 28 is provided near its ends with longitudinal slots 32, ,to register with the slots-24 or 26, so that the boltslS and 20 may be placed through said slots .to hold the severalparts together. V f The two uppermost elbows 2 of the frame are provided with pivots 24 adapted to detachably engage brackets 36 secured to the adjacent sides of the window frame as shown more clearly by Fig. 1. The brackets 36 have downwardly. and rearwardly extending slots 38to receive and carry the pivots 34 backwardly, so that they in turn will hold the'metal frame against the stops C. When the Window panes E are to be washed the metal frame carrying the screen 30 may be swung outwardly and propt in open position to gain access to said panes, or said frame may be entirely removed by disengaging the pivots 34 from the brackets 36, as preferred.

In assembling the screen frame the strips 12 and 14 are slipped into the respective legs of the elbows 2 and are adjusted longitudinally until said frame fits the window frame A. The wire screen is then laid across the back of the screen frame, after which the retaining strips 28 are placed against the back of the screen 30' and pressure is applied to force the same into the intermediate front portions 4L of the elbows and the corresponding portions of the strips 12 and 14:. This operation draws the screen 30 taut after which the retaining strips 28 are secured in place by the bolts 18 and 20,

which also firmly secure the strips 12 and 14 in the elbows 2.

While in the drawing I have only shown the screen frame covering the lower half of the window frame A, it is to be understood that said screen frame may be made in longer sizes to cover the entire opening'm the window frame A. I also reserve the right to make such changes in the construction, combination and arrangement of parts as properly fall within the spirit and scope of the appended claim.

Having thus described my invention, what I claim and desire to secure'by Letters Patent, is:

A frame consisting of elbows having inturned margins and outwardly projecting intermediate portions, side and end strips capable of longitudinal adjustment in said 7 elbows but held from lateral displacement by said .inturned margins, and retaining strips similar in cross section to the side and end strips and adapted to hold a screen in said frame.

In-testimony whereof I afiix my signature.

' WILLIAM LATHROPE WRIGHT.
