To all whom may concern:

Be it known that l, llAnIur L. THOMAS, a citizen of the United States, residing at Urn Lynne, in the county of Delaware an bate of Pennsylvania, have invented certain new and useful Improvements in Combination. Screens and Ventilators, of which the following is a specification, reference'being had to the accompanying draw- 111 's,

dhis invention relates to an improved combination screen and ventilator and an object of the invention is to provide an adjustable screen for insertion between the lower part of the lower sash and the base of the window frame, thereby screening the window as Well as constituting o ventilator.

The invention further aims to provide a device of this kind, which is constructed in two sections, slidahly connected or united,

whereby the combined screen or ventilator may fit window frames of various widths.

The invention further aim to provide means on the opposite ends of the sections, for locking the combined screen and ventilater to one of the guides cit-the lower sash. This locking or connecting means of the ventilator or screen to the guide for the sash is of such construction and design as to hold the screen or ventilator tightly against the lower rail of the sash when lowered, as shown clearly in Figures 1 and 2.

The invention further aims to provide a combined screen and ventilator, each section of which is constructed from a single piece of sheet metal. v

A further object of the invention is to provide a combined screen and ventilator that will lit any size window.

A. further object of the invention is to provide aj comhined ventilator and screen which can be so installed and regulated as to permit the window to be easily raised and lowered, and to further provide a'screen or ventilator, that can be easily manipulated by ahybody with case and convenience.

The combined screen or ventilator can be moved from one rooin'to another, and it is obvious tha'r the same is storm proof,

and since the screened openings in the sec- While the design and construction at present illustrated andset forth is deemed preferable, it is obviousthat as a result of a reduction of the invention to a .more

practical form for commercial purposeathe invention may be susceptible to changes, and the right to these changes is claimed,

provided they are comprehended within the scope of what is claimed.

lheinvention coniprlses further features and combinat on of parts, as will be hereinafter set forth, shown in the drawings and detail perspective "Fig. 4-. an enlarged plan view of the blank from which on e'ofithc ventilator is constructed.

Referring more especially to the drawings ctione of the "l and 2 designate the 'jtivo sections of the on and ventilator. As shown in Fig. l it obvious tl'iat e'ach section is constructed from a single-I piece of sheet metal. bent upon itself .3, to provide the Front downwardly. inclined face and the upper inclined portion 5. This portion 5 has an elongated opening 6, the marginal edge portions of which are slitted asshown at 7 to provide the holding tongues 8. 'lhcse tongues 8 are so deflected as to overlie parts of a piece of wire fabric 9, to cover the opening. By thisconstruetion it is to be noted that the pieces oi wire fabric may be easily removed, for the insertion of new pieces, if so desired. The sheet metal blank is bent upon itself as at 10, to provide the cud piece l1. and also bent at 12 to provide the end flange l3. When the blank is bent longitudimtlly upon itself as previously stated, and the bends l0 and 12 having been made, the flange is riveted to the under piece, thereby closing the end ofthe screen or ventilator section. in this regard each section of the ventilator is similarly constructed. It is to be noted that the opposite end oi each section is minus the endpiece,

thereby permitting two sections to he slidably united, one to overlie the other, as shown clearly in Fig. 1. The lower part of the front wall of one of the sections an outwardly turned flange 15, provided with a guide If to receive the outwardly turned flange 17 of the lower part of the front wall of the other section. The upper part of the sectionv having the guide 16, is provided with a guide 18, for the reception of the upper part of the other section. By virtue of these guides, it is obvious that the two sections may be slidabiy united one over the other. The end piece 11 of each section has a laterally disposed flange 19. A headed stud projects vfrom the end piece 11, and the shank of this stud 20 engages through the slot 21 of the adjustable plate This plate 22 has a thumb engaging flange 23, and is also provided with an additional flange 24, to cooperate with the flange of the end piece 11, to lock the screenor ventilator and the inner guides of the lower sash, so as to hold the upper part of the screen or ventilator tightly against the inner surface of the lower rail of the sash. In order to fasten the screen or ventilator in position, the plates are moved upwardly and outwardly, so asto widen the space between the flanges of said plates and the flanges of the end pieces, to permit of the reception of the guides for the lower sash of the window. After the guides of the lower sash of the window are inserted between the flanges ot' the plates and the flanges of the end pieces 11, the plates may be adjusted downwardly toward the lower rail sash, so as to clamp the guides between the cooperating flanges.

The invcntion having bccn (l lorth. what is claimcd as new and useful is;

1. In a combined scrccn and ventilator, the. combination with a pair of sections slidably united and provided with scrccncd openings, the rcmotc ends of the sections having end picccs provided with ll:l|l; "t. and movable members carried by lhc end pic c having mcans cooperating with said llangcs tor clamping the guides for the lower sash of a window.

Z. in acombincd screen and ventilator, the combination with a pair of sections. of means for slidably uniting the two sci-lions. said sections having scrccncd openings, the remote ends of the sections having cnd pieces, and means carried by the end pieces for clamping engagement with the guides for the lower sash of tlic window.

3. In a combined. screen and ventilator, the combination with a pair of sections, of means for slidably uniting the two sections, said sections having screened openings, the ren'iote ends of the sections having end pieces, said end pieces having flanges vertically disposed. plates huvingtlangcs to cooperate in parallelism with the first flanges for clamping the guides for the lower rail of a window, said plates having inclined slots, and means passing through the slots and carried by the end pieces, for slidably supporting said plates.

In testimony whereof I hereunto atiix my signature in the presence of two witnesses.
