- Application filedAugust 17, 1926. Serial No. 129,762..

This invention relates to new and useful improvements in window screens of the rolling type and has for its primary object to provide a screen constructian that is at-' tached to the lower frame bar,-the lower window sash at one end and arranged withina housing at its opposite end and being of such a construction that when the window is raised the screen will be extended nation, and arran from the housing and that when the win-- dow is lowered the screen will automatically move into the housing. j

, One of the main. features ofthe present 'inventidn resides in the provision of means for causing the screen material to automatically wind within a casing as the window is lowered and this without the provision of the usual spring roller now depended upon in the operatlon of rolling screens ofthis character.

A further and important feature of the invention is to provide guide means for the side edges of the window screen. so as to overcome any-buckling of the screen while being raised or lowered, said guidemeans being further provided for covering a slot in the top side of the screen casing when the window is lowered or when the screen is not desired foruse.

Other objects will ,become apparent as the nature of the invent-ion is better understood the same comprising the novel form, combiement of parts hereinafter more fully descri ed shown in the accompanying drawing and claimed.

In the drawings wherein like numerals indicate like parts:

Figure 1 is a fra entary view in side elevation of a built i fg window equipped with my novel screen construction-which is fragmentarily disclosed in extended position.

Figure 2 is a detail vertical section thereof.

Figure 3 is a fragmentary longitudinal section for disclosing the screen casing in top plan and the screen guide means in cross drawings,

with a pairof conventional sliding sashes, the lower one of which is disclosed and designated by the reference character B. The present invention consists of a metallic cas- -1ng"5 of heavy-metal, and of circular shape information. This casing consists of; a pair of telescopic sections 6 and 7 in order that the length of the same may be increased or diminished at will. Formed or arranged 1 thereof is a suitable bracket 8 that is constructed forflush engagement with the sill C of the window to'permit of the attachment of the casing to the sill by' reason of bolts or screws 9. 1

Rearwardly of' its center, said casin is formed at its top side with a longitu inal slot 10, while at opposite ends of the section directly above the slot arevertical lugs 11- 11 to which are pivotally secured the lower ends of L-shape length substantially equivalent to the length of the respective sections of the casing 5. The invention further consists of a pair of screen strips 13.13 of a width substantially equivalent to the length of each of d guide bars 1212 of aon each of the sections at the bottom side length. The inner edge of these screen strips are arranged in overlap ing relation as 'clelgrly disclosed in both-Flgures 1 and 4.

1g1 dinal edges of the screen strips 13--13 are reinforcing strips 14 of spring metal that is normally of coil formation.

In actual practice the casing 5 is first an-' chored to the sill of the window after which the guide bars 1212 are raised vertically into contact with the inner surfaces of the side bars of the window "frameA, and inwardly of the sash B. Th outer ends of the screen strips 13-13 are then' attached to the lower bar of the sash frame in an desirable manner. Obviously when the sa is raised, the screen strips will be drawn from the-casingto cover the opening'beneath the sash. By reason of the spring strips 14 of normallycoil formation, the screen-strips will be drawn into the casing andi be rolled therein when the sash is lowere It will thus be seen that I have provided 'a highly novel, simple and eflicient screen construction for windows that is well adapt-' described the lnventi'on as consisting of cordly attached to .theopposite longitutsin detail structural elements it is neverthe= less to be understood that some changes may be made therein'without effecting the spirit and scope of the appended claim,

Having thus described theinventiomwhm; I claim as new and desire to secure by Letters Patent is:

In a' screen construction for windows, a hollow casing constructed for disposition upon the window sill, said casing; being formed at its top 'side'with a longitudinal slot a predetermined length of screen we terisl, reinforcing strips extehding along the a sesses opposite longitudinal edges of the screen macoil formation within the casing, the outer end of the screen material being attached to the lower portion of the adjacent sliding window sash in order that when the sash is raised, said screen material will he withdrawn from the casing through the longitndinal slot In testimony whereof I efiix my signature.
