To alliwhom "it may concern;

Be it known that l, lNILLIAM J. BAKER,

residing at Newport, inthe county of Campor bolts.

Specifically my inventionembodies an imoroved construction of frame having interoclring parts for the screen clamping portion, so arranged that the screen can be readily removed from the frame for replacemerit when worn.

In, its more subordinate nature, the in vent-ion embodies certain novel features of construction, and detailed arrangement of parts, all of which will. be first described, then be specifically pointed out in the appended claims, and illustrated in the accor panying drawings, in which Figure 1 is a front elevation of a screen embodying one form'of my invention, showing how the same maybe secured in the Window frame. -Fi 2, is a horizontal section von the line 22 oil Fig. 1. Figs. 3 to '16 inclusive are detail views of various modifications hereinafter specifically referred to.

Referring now to the accompanying drawings, in which like letters and numerals of retterence indicate-like parts in all of the figures, itwill be seen that the screen A comprises a sheet metal frame consisting of the top frame section a-and the bottom frame section 7), both of which may be of the same cross sectional type, or form, while the side sections 0 maybe of-the same sectional -form as the too and bottom sections a and b, or

they mayliave a different sectional form and prcvidedwith integral guides, when 1t is desired to use the metal screen in a Window frame having wooden slide bars B 1n place of metal slides.

ries sliding lock members D to engage the slide bars B, the sliding lock members D being capable of withdrawal from engagement with the slide bars l) to permit of the removal of the screen. The screen also includes a wire screen section V? which is held by the sheet metal frame sections a, b and c.

The frame sections, a, l) and c ma be of various forms in cross section and I have illustrated numerous modifications of my improved form of screen in the accompanying drawings by reference to which it will be seen tlin the form shown in Fig. 3,. the

screen f1 ame section consists of a list bottom I or base 1 with upwardly extending integrally formed

sides

2 and 3 arranged parallel to one another and spaced apart, the upper ends of which are bent as 2 and 3, one of said ends 2 overlapping the other 3 as shown. Each of the

overlapping ends

2, 3* have their edgesbent back upon themselves as at 3* and 2 res actively, the edges 2* and 3 being bent to he between the

ends

2 and 3 respectively, as clearly shown in the drawings.

The screen wire W is clamped between the

ends

2 and 3 and the

edges

3 and 2 and the side wall2 of the frame section, as clearly shown in the drawings, giving the screen wire, as it were, an S-shaped bend Where it passes between the

ends

2 and 3 of the sheet metal frame section. It will also .be seen that by this construction the edges 2 3 lie substantially in the same plane when the screen is clamped in the frame and thus prevent the screen drawing out, and furthermore keep the

sides

2 and 3 in parallel relation.

Instead of making the screen sections in one iece, as shown in Fig. 3, the same effect can e obtained by constructing the sections as shown in Fig. 4, wherein the screen section is formed of two parts, the base 1 being formed partly on one part and partly on the other, and consists of the portion 1 bent at right angles to the side 2 and toward the other side 3 and given a slightly curved. form to cooperate with the base portion 1 that is formed with the side 3 and extends toward the side 2, the edge of the base portion 1 being bent under, as at 1, to cooperate with the.

base portion l and form, as it were, a rigid structure. g I In Fig. 5, I have shown a further modificain place and by reason of the folded or bent this-{form of my invention the bent over edge 1 into two different planes, one portion 1 of 5 gether into a rigid structure.

' the drawings and in this form where the side form shown in Fig. 4:, but the base 1 in this from the side 3, the edges of which are bent the edges 3"'2 of the screen clamping por- "tion of the frame, and when this form s tion duly performed, the bottom-1 is bent tion of my invention, and in this form the screen section 1s made in two pieces, as in the form consists of flat base portions 1 bent over at right angles from the side '2 and the fiat base portion 1 bent over at right angles over as at 1 and l, in a manner similar to used, it will be seen, when the two parts are placed togetherthey will, owing to the resiliency of the metal, spring lock themselves over edges.1 1- and 3' 2 the twoparts will be prevented from coming apart.

Fig. 6, shows the same general idea disclosed in Fig. 5, with the exception that in 1 is omitted, and in order to have its func-' upwardly to form a bead 1 which corre-' sponds to the end 1 of Fig. 5-.

In Fig. 7, I have shown the same form of screen shown in 6, but .adapted for use as the side screen section '6, of the-screen, and in .thisform an integral guide l is projected downwardly from the member 1 and this guide may haveits end 1 bent back to form a stiffening portion, as may be found desirable.

Fig.8 shows essentially the same idea disclosed in Fig; 7 with the. exception that in this form the bent over edge 1 is omitted and its function is performed by providing the bottom 1 with a bead 1 to bring the bottom apping, as before, but each of these bottom portions 1 1."are provided with a longitudmal corrugation or bead 1 and 1 which are i 1 adapted to register with one another and thus lock the two bottom portions 1 1 to- Fig. 11 illustrates the same form shown in Fig. 10, with an integrally formed guide 1 formed with the bottom portion 1 Fig. 12 illustrates a further modification of the clamping surfaces of the frame section. ,In this form the upper ends of the sides 2 & 3 are bent inwardly toward one an other to lie in arallel planes, as at 3 2 in a manner similh-r to that shown inFig. .3 of

3 and ends 3 meet an inwardly depressed corrugation 3 is provided to cooperate with.

a bead 2 correspondinglyformed on'lthe edge of the end 2'. v

Fig. 13 shows another modlhcatlon of the general type disclosed in Fig. 3, of the drawings, but in this form the bent over edge 3 is omitted and 1n lieu thereof its function is performed by bending up the edge 3 of the end ,3 of the side 3 thereof so as to form a channel for the screen of substantially an S-shape similarly to the mannerdisclosed' in Fig. 3, but in this form the base 1 is formedintegral with the

sides

2 and 3.

Fig. 14 illustrates the same formshownin Fig. 13 with the base lforined of two members, one of which 1, is formed with the side 2 and the other 1 is formed with the side 3, the two members over-lapping and interlocking, as shown.

F ig. 15 shows another modification of' my invention which is. substantially the same as Fig. 12, except that both the top and bottom portions of the screen sections are formed alike and in this form also the fixed guide 1 may be provided, or omitted, as the case may be.

From the foregoing, it will be seen that in each from of my invention the screen frame section comprises a base '1,

parallel sides

2 and 3 and a top 5, formed by bending over the upper ends of the

sides

2 and 3, as hereinbefore described, and in some cases the bottom is made by bending over the lower ends of the

sides

2 and 3 as at 1 -1 thus forming what is known in the art as a twopiece screen. When I refer to the upper ends of the

sides

2 and 3 of the screen section I intend that term to be read inconnection with the parts in the position shown in Sheet 2 of the drawings containing Figs. 3 to 16, inclusive, and to include within its definition the parts ,2 --3 of the

sides

2 and 3, and the equivalents of

such parts

2 and 2 the expression upper ends being a relative term used in order to clearly define the features of applicant's invention.

From the foregoing description taken in connection with the accom anying drawings, 1t 1s ,thought the -comp ete constructlon, operation and many advantages of my mvention will be readily understood by those skilled in the art to which the invention appertains, andin order to release the screen cloth from the frame, it is only necessary to insert a screw driver, or other'similar tool, between the

ends

3 and 2 and pry the same apart, thus permitting the

sides

2 and 3 to be pried apart out 'of parallelism, or when the form of the general type shown in Fig. 5

is used, by prying apart t e ends 3 and 2 which form the top the part having the side 3 may be entirely removed.v

Any suitable corner braces nlay be provided for'the screen, such for instance, as

shown in Fig. 16, of the drawings, by refer-- over end of one side portion projecting toward that of the other side portion, one of said ends overlapping the other, said ends being provided with portions lving in the same plane and other portions lying in different parallel planes, and a wire screen member clamped by said frame section, substantially as shown and described.
