To all whom it'may concern:

Be it known that I, Wmrmno B.-'PHIIr use, citizen of the United States, residin at Fenton, in the county of Genesee an State of Michi an, have invented certain new and useful m rovements in Window- Screens, of which t I e following is a specification.

The present invention relates to screens andmore particularly, the invention is designed to provide in a screen, a novel constr'uction and arrangement ofparts looking to 'a reduction in t 0 cost of manufacture, efficiency in operation, and combining strength and durabilitywith lightness} It is a matterof common knowledge that screen sections formedofwood-with parts slidably interlocked, will, in the course of time, warp or split or swell and become forced into wedging contact at their connecting joints, thus rendering it diflicult to adjust the sections. I

In an endeavor to overcome the above difiiculties, it has been proposed to constructenall-metallic screen ora" screen in which the framework is wholly of metal but all of theseconstructions, with-which am familiar, aremore or less faulty because of their weakness, andthe tendency to wabble bend or buckle. It has also been proposed to reinforce the screens which are formed wholly of metal at the corners thereof since if the corner joints are not reinforced with an extra corner piece, they are so weak that the frames readily collapse, but such constructions have proven objectionable, because of the increased cost incident to the metallic joints at the corners and the likelihood of said corner pieces becoming detached. 4

It is contemplated by'the resent inven-' tion to overcomeexistingde sets and may be said to comprise screen frame sections, the sides of which are wood, and the interlockin 'tops and bottoms of which are of metal %ormation throughout, with the result that any binding at the'slidable' interlocking parts is absolutely provided against,-and at the same time the sides are rigid and effectively resist the shock of slamming the sash down upon the screen. The improved method of corner construction provides rigid and stiff frames,

insuring the greatest possible stren th and durability at the smallest manu acturing cost.

' Other improvements and novel details in the constructionand arrangement of arts will be more particularly referred to ereinafter and the description to follow should be rea in connection with the accom anying drawings, forming a part hereo and w ierein is disclosed, for the purpose of illustration, a satisfactory embodiment of the invention.

In the drawings, Figure 1 is a front view of a screen comprising two sections slidably interlocked, Fig. 2 is an end view of one section, Fig. 3 IS a perspective view of one corner cut away, Fig. 4 is a detail view of theinterlockin connection between the screen sections, igs. 5, 6 and 7 are detail sectional views.

Referring more particularly to the drawings, like reference numerals refer to corresponding parts throughout the several views, and'the' screen is'shown as comprising two sections slidably interlocked one with the other, whereby the screen is adapted to fit windows of various widths. One of the screen sectionsis preferably made up of an and frame in two'parts, the lower one 1, and the upper one 2, being of wood construction and preferably solid throughout, the sections 1 'and 2 being secured together in any desired manner as by nails or the like 3, and adapted to support therebetween one edge of the screen member'4. The top and bottom framemembers of this screen section are of metallic formation throughout, and are substantially the same in construction, so that a descriptlon of one will suffice for the other. In forming the top and bottom frames, an elongated strip of sheet metal or the like isprovided,'th'e same being bent longitudinally upon itself thereby presenting a double thickness for added rigidity and strength. The free edges 5 and 5" are adapted to overlie the adjacent edges of the screenand be secured thereto if desired, but it is found in practice. that this securing means may be done away with, since the edges 5 and-'5' are adapted to rest in a recessed portioml at the end of the bottom .end section 1, and in this way will frictionally hold or clamp the screen. The edges 5 and 5 are secured in position through the medium ofinail's or the like passing through the top e'ridSetition 2. The metallic strips are then bent longitudinally so as to present an angled extension 7 adapted to fit over the end ofthe end frame section 1, andsaidmetallic strip is'fnrther bent longitudinally, to l present an angled sectiorrS, which overlies, the under surface of said end section 1. Se-

curing nails or the like pass through the metallic strip and the end of the section 1, as at 8', and similar securing devices pass through the metallic strip and'under surface of the end section 1, whereby the metallic strip is secured at a plurality of points and firmly supported thereby. F It is observed thatsince the, metallic strips constituting the top/and bottom frames of the section extend over the end of the end section 1. the groove or guideway formed between the bent edges of said strip is provided witlrafilling at its end/tending to prevent any collapsing and maintaining a practically uniform guideway or groove for the interlocking tongue formed by the top and bottom frames of the cooperating section.,

The cooperating section of the screen comprises an end frame made up ofthe lower part 9 and upper part 10 secured to one another as by nails 11, said parts being constructed "of wood, as are the parts 1 and 2 of the cooperating section, and adapted'to support therebetween. the edge ofthe screen member 12, a The top. and bottom frame members of this screen section comprise metallic strips, conveniently sheet metal, bent longitudinally uponthemselves withthe free edges 13 and'14: thereof overlying the adjacent, edges of thescreen member This metallic strip is bent at an angle mtermediate its ends, the angle portion 15 being of a width to freely play in the groove formed by the cooperating metallic frame of the other screen section, whereby the-screen sections are free to slide relative to one another. The overlying free edges 13 and 14 of the metallic strip are arranged to rest within a recessed portion 9 in the end of frame member 9 and to be secured in position by nails or the like passing through the other end frame section 10. Again, the an.- gled flange 15 of the metallic strip "fits over the endof the end frame part -9 and is secured thereto as by nails or the like 15.

The inner edges of the screen memberare supported between overlying edges 16 of metallicbrace bars 16, which latter areconveniently of sheet metal construction and haveflat ends- 16.-fitting between-the free edges of the. folded metallic top and bottom frame sections, and-secured ,by means of nails or thelikeat 16. These .brace=bars 16 the outward sliding "ble screen is provided, one whic an operation, -connect1ons are free from any are laterally oifsct at 17, said oli'set portion adapted to contact with the screen of the cooperating section. thereby providing a close fit, and the offset portions of the respective brace bars constituting means for limiting movement of the screen sections, and preventing separation thereof.

By the construction ust described, it 'Wlll be appreciated that a very stron and durais efficient since the interlocking sliding binding action or swelling and war ingincident to weather influences, and at t e same time the screen is strong and durable since the end parts or sections are of solid wood construction, thereb reinforcing the sheet metal construc tion 0 the interlocking sections and affording means capable of withstanding the jars and slamming of the window upon the screen in the usage of the same. Again, it should be borne in mind that were the end sections of the screen formed of metal, the weight will not only. be increased, but the expensive constructions at the ends looking to rigidity will vastly increase the cost of production.
