WVhile my invention is adaptable for holdving' down the flexibleelements of various rolledclosures for windows and the like,

screen closures; These comprise generally ahou'sing at the top of the window opening containing the well known spring roller upon which the screen is wound," and supports therefor. .The scireen itself'is prefer- -vably specially woven ofthe correct width and there areprovided guides into which {the-edges of the screen may enter so as to r a effect a completeinsect-proof closure for the i v drawn from the housing bymeansof a tenentire window spacewhen the screen is withsionbarn It 1s an ob ectof my lnvention' to prov de a 1 construction of guides'and tension bar which Qutilization of such agencies as are possessed by the Imanufacturer of metal-framed It is an object of my invention to }provide a construction which is readily attached-to a window opening in cooperation ischeaply and-easily nmade through the with-the housing containing the roll; Furany desired position along thefguides, or fully closed withouta latchgit nevertheless is and all of thisin aconstructionwhich is very inexpensive These and other objects of my invention will be apparentto one skilled in -the art upon reading these specifications;

ther it is my objecttodesign the guides and bars so; that; while the screencan be held at v Figure 6 is a view from the rear of an end thereof. v I 1 i Figure 7shows one of my guides.

The screen guides, as will be seen in Figures 1 and 7' are formed of two pieces of sheet metal 1 and 2 on each of which there is a turned over edge portion 3 and 4, the pur-i pose of which is to provide a thickened and reinforced edging for the slot 5. The metal piece 2 is bent in a general U shape to provide the guideway 6. This is of rectangular cross section inside and out, and furnishes a channelin which one member of the tensionbar slides "as will be fully described. The pieces. 1 and 2 are fastened together along their flat portions by rivets 7 as shown in Figure 7, or by spot welding, or may be onepiece of metalfolded on itself. The flat portion may also where desired be perforated for the passage of screws or bolts to The shape of the guides will be understoodby reference to Figure 7 and it will be clear that the shape of themembers is such as to provide a flat portion for attachmentya channel or guideway anda slot. The portions 3 and 4 approach each other closely, since thisjslot, whilevwide enough toallow free passage for the edge of the screen, and the easy working ofthe tension bar, must be narrow enough to cooperate with the screen-edge in forming an insect-proof closure. I i, 4

My tension bar comprises a main or body member 8 of sheetmetal'bent upon itself as is shoWninFigureZ. The front ofthe bar will have the appearance of a solid bar shown in Figure 5'; but from the rear it will be seen that the metalforms a rectangular D section (9 inFigure 2) of less thanthe' full width of the bar, and that one arm of the D'isbent over so as to lie parallel with the face of the bar and is preferablyfastened thereto for strength, as by spot-welding. The

projecting end of the metal beyond the D is This construction forms a channel 13, witha in which the screen is fastened; and'it will be, observed. that the bent-over section .12 forms. a shoulder within the said channel.

To fasten my screen, I make use of a member ofspring sheet-metal shaped as shown in Figure 3. There is a screenengaging edge 14, a shoulder 15, a U shaped portlon v 16,-and a fiat portion 17 adapted to lie above the The method of attachment of the screen will be understood from F1gure'4; where the screen cloth 18 is shown as enter- I ing thechannel'l? The screen fastening clamp of'spring metal is insertedover the screen cloth in the channel 13. The springiness' of the metal causes the clamp to expand in the channel, pinching the screen against the shoulder at 12, and holding it fast to the channel bar. It Will be obvious that other means than the specific clamp which I have illustrated and described may be used if desired to hold the screen in the channel.

Having now described my guides and the tension bar body together with the preferred method of fastening the screen thereto, I will in the guideway and of sufficient length so 7' that the tension bar may be held throughout "itsfmovement in fixed angular relationship tot-he guides, a narro w'member rpassing through the slot and adapted to'join'the first member to the tension bar, and frictional means restricting the movement of the first finentioned member'in the guideway.- lrVhile these means may, if-desired 'be constructed integrally with the tension bar, I prefer to embody them in a separate metallic struc- I ture which is shown clearly in Figure This structure is formed of a single piece'ofsheet metal cut and bent so as to form a back piece 19 upon one end of which are upset two pieces 19 forming'what might betermed atongue.

' This tongue fits within the D section of the tension bar tightly, so as to fasten the piece 19 very firmly thereto. Upon the other end back, ends,

of the back piece 1 9, the metal is bent "so as to form a boxlike section 20, closed uponits and sides but open toward the tension bar. The shape of this boX section is such as to allow it to slide within the guide Way while conformingyery closelythcreto, j

- -anol' its'length is such' as to maintain 'affixed angular relationship bet-ween the guide and the tension bar as Will be understood 'Wi-thin the section 20 I place a spring '21,

the purpose of which is to bear against the I side of guide vvay to'cause the portion- QO-to bmdtherein sufiiciently so that my ten sion bar may be held against the tension of thejspring operating upon the screen in any 6o desired'p osition along the, guideways. I In operation the screen cloth lies in the guides and extendsbeyond the tension bar .proper, {and in order to minimize wearf in the-slot of the guides,l prefer to protect the iewe r edges '-ofthe cloth by thin sheet metal Y Broadly these members 22, which may conveniently be of thin sheet brass or copper, and which l e along the back of the part 19 as shown 1n Figure 6 and are held thereto by a rivet 23.

In this specification I have'described a specific embodiment of my i'nvention lout various modifications therein are posslble to one skilled in the art without depart ng from j the spirit of my invention. 7 Having thus described. my i vention, what I claim as new and desireto secure by Letters Patent, is l 1.
