Application filed April 15, 1916. Serial No. 91,453.

To all whom it may concern:

Be it known that I, SWAN G. ANDERSON, a citizen of the United States, residing at Virginia, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Window-Screen Frames, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to frames for windows and especially to such upon which wire screen is stretched and placed within.

window openings to act as a barrier to files, mosquitos and the like.

The principal object in view is to provide a frame of this character composed wholly of metal made of a plurality of unassem bled interlocking and telescoping parts that may be obtained in such knockdown form and subsequently assembled by the purchaser in such a manner as to perfectly fit his individual requirements.

Another object is to provide such a frame wherein the only tool necessary in assembling same is a ammer.

Other objects and advantages will appear in the further description of the device.

In the accompanying drawings forming part of this application and in which like reference characters represent like parts:

Figure l is a plan view of the interlocking parts of the frame.

Fig. 2 is an illustration of the method of assembling a corner of the frame.

Fig. 3 is anunder side perspective view of oneof the corners of the frame after being assembled and clenched.

Fig. 1 is a cross section taken on the line mew, Fig. 1 looking toward the center cross bar, and

Fig. 5 is a perspective view of one of the fastening clips.

In Fig. 1 one complete side of the'frame is illustrated and having adjacent the ends thereof, the fractional'ends ofeach cooperating side, it being understood thatthe construction of the four sides are identical.

Each sideof the frame is composed ofa female member formed of a flat piece of sheet metal bent longitudinally at right angles as at 1 forming a horizontal. floor ortion 2 and verticalwall portion 3. The extreme upper edge of the wall 3 is bent in wardly and downwardly forming a longitudinal flange 4 at an angle to the wall 5.

The free edge of the floor downward, forming tongue 15 extends 2 is also turned inward forming flange 4 though is greater than wall 3. .7

The end of the female member which is designed to receive one end of the male member forming the adjacent side of the frame is provided with an opening 6 across the floor thereof, formed by cutting three sides of the depending tongue 7 therefrom and spaced a distance from the end, and the flange 5 terminates a distance from the extreme end just equal to the width of the floor of the male member.

The male member which snugly telescopes within the female member and completes one side of the frame, is formed in cross section identical with the female 'member, except being just sufficiently smaller to properly fit therein and that the upper flange 8 thereof may not necessarily be as extensive but preferably at least sufii a flange 5 similar to the that of the flange lto the cient to form a smooth iron-cutting edge to the wall, 9 of such mem- The flange 10 upon the floor 11 of the male member terminates a distance from the free end of the member just equal to the width of the cooperating end of the adjacent side ofthe frame and the extreme end 12 of the wall 9 extends considerably beyond the end whose angle to the base 2 of the floor 11 and is bent at right angles inwardly to fit in under the flange 4: of the cooperating end of the adjacent side of the frame.

' The extreme outer end of the floor 11 0f the male member is cut away somewhat as at 13, out again as at 1 1 and lnward a distance.

from the end just equal to the len h of the opening 6 in the depending curved tongue 15 which snugly fits within theopening 6 and upon the correspondingly shaped tongue 7 when the corner of the frame is madecomplete by the assembling of the cooperating members.

-llt-is evident that from thefact that the below aplane with the lower face of the bottom t being engaged therewith to admit of the end 12 being surmounted by the flange 41 of the female member. I Then as the vertical walls of the two members are thus enteredgthe tongue'15 of the entering member may be snapped into to be tipped up somewhat 11 the male mem- 7' hll place within the opening 6 in the receiving member by bringing the two members into alinement.

The attitude of the engaging members for such assembling is clearly depicted in Fig.

of the drawings. After th thus engaged they four telescopic sides to the rame, as described, it is evident that such be adjusted within certain limits to flt any sized opening preparatory to the wire screen being applied thereto.

fter the corners of the frame are assemhen the wire screen 16 is cut of a size to freely fit within the side walls of the frame and rest upon the edge of the flanges 5 and 10 now completely surrounding the inner wall of the frame.

0 bind the screen to the flanges, flat metal strips 17 are placed upon the edges thereof and forced downward within the side walls of the frame members and held therein by transverse clips 19, any number of which, to suit circumstances, may be employed.

One edge 18 of the strips 17 is preferably in the form of a flange by being slightly turned at an angle to the body portion thereof, and against which the end 20 of the clips 19 are designed to impinge when the downward into place. By of the strips is snugly against the screen under the flanges of t 1e frame, a firmer joint resulting than if the strips were not flanged.

The strips 17 may be composed of one or more pieces for each side of the frame as desired and may be readily cut to suit individual requirements.

In a frame of this character, large to require additional strengthening, I provide a telescopic cross bar comprising sufiiciently the male and female semi-tubular members 22 and 23 respectively, the ends 24 of which are pinched tightly together and bent at right angles to the body of the bar. When in place within the frame, the ends 24 are sprung in under the flange 4c of opposite sides of the frame and the flange forced tightly thereagainst with a hammer.

While the body portion bears against the screen upon the edge of the flange 5 of the frame, the members comprising the bar may be fixed against longitudinal movement by being forced together with a hammer and tie screen fastened thereto by a suitable iece of wire 25, where desired.

Thus I have provided a form of screen frame that can be made of a plurality of relatively small and inexpensive pieces of scoping members, the innermost flange be ing for the reception of a suitable wire screen, strips for placing within and holding the screen against the flange and clips for holding the strips securely in place.

2. A screen frame of the character described comprising side members of angular shaped pieces of thin metal having inwardly turned flanges formed upon the opposite edges thereof, the innermost flange being for the reception of a suitable screen,
