D. G. HARVEY SCREEN STRUCTURE Filed Sept. 16. 1929 Feb. 3, 1931.

Patented Feb. 3, 193 1 DOUGLAS GRAY.HA-BVEY, or DIXON, znninorslnssicnon To nnYivoLns wrfaii 0b.,10F 1 DIXON, VILLIANQIS, n conronnrron OF ILLInoIs v scams SiTR'UGTfiBiE Application. filedseptembcr 16, 1929.1 semi m3. 392,7e'of My invention relates to screen structures of the type adapted to be positioned over window or'door openings and on-porches and the like to prevent theentry thereinofinsects.

It is now customary in screening windows and doors to provide a wooden screen frame which'is inserted into the window or door frame and to which the screen is attached. It is apparent that to prevent the entrance of insects it is necessary that this screen frame. be made to fit the window or door frame accurately. At the same time,in order toenclude as little light or air as possible, 1t is necessary that the sides of the frame be relatively narrow. Thus, there is'the necessity for an accurately shaped but lightly constructed frame the construction of which requires considerable skill. For this reason 1t is usually sert in or remove from the frame, and tend to corrode and thus discolor the adj acent frames or walls. It is also difficult to properly stretch the screen across the openlng to provide a uniformly taut screen-throughout its area. This is one of the greatest 'difliculties the'average individual encounters inapplying screens.

In order to overcome these difii'culties I have provideda screen structure which may be easily and properly applied bythe average individualfwithout the use of tools otherthan' a hammer, to the frame itself in the case of windows or if desired to frames of the usual I type. It will be apparent that when used upon openings, such as doors, it is necessary; to employ a screen frame topermit the screen to be opened and closed. The screenstructure comprises a screen arrangedtobe tacked over the opening and strip -materlal adapted to be positioned on the frame at the edge of the opening, having-an inwardly. pro ect1ng' bead for tightening the screen;

One of the objects of my invention 1s the provisionlof a screen structure which maybe manufactured and applied at a relatively small cost.

I have also aimed to provide a screen struc 3 ture adapted to be applied directly to a win-- dow or door frame-eliminating the use of the customary screen frame. r i Another objectof-theinvention is the provision of a screen structure havingmeans' for easily and un formly tlghtening the screen.

'A still further object of the invention ish 7 the provision of ascreen structure-which may be appl ed by the average individualwith the use of a hammer alone. r

O-ther objects and advantagesof improved structurewill become apparent from T the following disclosure and the ing drawings, in 'which 1 Figure l isa perspective showing the-screen structure applied to a window frame;

accompany I Fig. 2 is a section; showihgthscreen held 7 against the lower sill and is a section on,the-

line 2-2of Fig.1; 1' o Fig. 3 is asection on the line 3.3'ofFig. 1

and shows the manner in which the strip ma terial rests againsttheframeand tightens the wire screeny I Fig. 4 1s a viewof a corner member showing 't'he reenforcing ribs and a' portion .of the strip material;

Fig." 5; is asection on the 1156.595 ofFigL: 4 and shows the manner in which the strip' ranged tobe-positioned over anopening such as that formed by the window frame indicat'ed' generally by 9 inFig. 1. The wire 7 screen 8 may be loosely tacked thereon: by means of tacks "10 or'other suitable means. -While the screen may be laid flat upon the sides ll and 12 and the top 13 of the frame it is necessary to bend the'screen a right angle or -more' at the bottomand tack the lower end thereof to the sill, since the latter projects out beyond the other members of-theframe. The manner in} which this is per formed is clearly shown in Fig. 2. :It will be. apparent that burlap, cloth, or the like, may

be applied to the frame in like manner.

In order tocover the edges of .the wire screen'whioh has been applied tothe frame in the manner indicated strip material designated generally by 14 is applied to the inner edge of the frame 9. This material consists of metal strips having a central portion 15 provided with reinforcing ribs 16 extending crosswise thereof, as best shown in Fig 4. The sides 17 and 18 of the strip material ex tend downward on either side of the central portion, as shown in Fig. 5, the side18 having its lower edge beaded, as shown at 19, to promer is positioned to extend over the edge of the frame into the opening, as shown in Fig. 3. The lower. edge of the side 17 lies in contact with the frame 9 whereby nails 20 driven through openings in the strip material and into the frame 9; cause the edge '19 which lies in contact with the wire screen 8 to be drawn over the edge of the frame and tightened. It will thus be apparent that if thenails passing through the strip material 22, 23 and 24 on the sides 11, 12, and 13 of the frame are drawn do'wn'to approximately the same extent the' screen will be uniformly tightened ifthe edge of the screen in contact. with the sill 21 is'held stationary. 7

In order to cover the lower edge of the screen in contact witlrthe sill 21 and hold it firmly during the tightening operations described, strip material'25 is positioned thereon as shown in Fig. 2 with the edge 19 thereof 1 holding the screen tightly against the sill 21.

A feature of the invention is the provision of scores 26 and 27 at intervals throughout the length of the strip material, the scores being. placed, opposite each other, 26 inthe it side 17 and 27 in the side 18. It will be apparent that the individual seekingto apply the screen structure may easily breakthe strip material to provide a suitable length there-ofpsuch as a side 28. 'However, the

4. length thereof conformingto a score in the strip material may be shorter than the desired length whereby a small space may be left at the corner of the frame. tancewil-l be covered by the ends of the corners presently to be described Referring now more particularly-to Figs;

land'tx, the corner members will be seen to be constructed in the same general manner as thes'trip material. The inner side 28, however, corresponding to the side 18 of the strip material, is bent vertically downward and the central'port'ion 29 corresponding to portion 15 of the strip material is made to extend inward to a point even with the edge19, as best shown in Fig. 4. A side 32 is similar This disto and corresponds to side 17 iAn outwardly projecting lip 30 is provided'on the inner edge of the corner and is arranged to bear against the wire screen at the corner of the frame and tighten the screen thereat. Reinforcingribs31 corresponding to ribs 16 in size and shape areiimpressed in the corner members. The ends 33 and 34 of the corner members are of suflicient length to cover any portion-of the fra'ine' sidesleft uncovered due to breaking the strip material at a score point.

In the. drawings, the length of each end is equal to or slightly greater than the distance between the scores onthe strip material.

It will be apparent from the foregoing thatI have provided an economical but high- 1y improved screen structure which, may be easily, xquiclrly,.and, conveniently applied by i .the average individual 'tdproduce atight' wire screen, pleasing in appearance. It provides a means for applyln'g screens to openingswhere the cost has hitherto been'pr'oh'ibit ve because of the necessityof employing a carpenter or others'skilled in the work to produce frames for the screens and mount the wire screen therein.

WhileI have thus described and illustrated aspecific embodiment of my invention 1 am aware that numerous alterations may be made therein withoutdeparting from the invention and I donot wish to belimited except as required by;the 'prior art and thescreen,.and means acting between'said frame and strip material for tightening said screen.
