CHARLES A. LLOYD, OF BALTIMORE, MARYLAND.

VENTiLATiNG-AWNING.

SPECIFICATION forming part of Letters Patent No. 476,662, dated June 7, 1892.

Application filed April I, 1890. Serial No. 346,536. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES A. LLOYD, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Ventilating-Awnin gs; and I do declare the f ollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

My invention relates to certain novel and valuable improvements in ventilating awnings or shades for windows, which improvement will be fully understood from the following description and claim, taken in connection with the annexed drawings,in which Figure 1 represents a perspective view of a window with a sun-shade embodying the invention attached. Fig. 2 represents a front view of the window-frame with the shade drawn up. Fig. 3 represents a transverse central vertical section of the frame and attached shade. Fig.4 is a reduced view in detail showing the sliding connection or sleeve of the cloth with the upper jointed frame, and Fig. 5 is a front view of the awning as it appears with both frames depressed.

Referring to the drawings by letter, A designates a window-frame comprising the sill B, the jambs G C, and the top rail D.

Secured to the sill B, preferably centrally between the jambs, is the cleat b, and to the inner surfaces of the sills O C ararespectively secured the similar cleats o c at a convenient height above the sill.

Secured to the lower surface of the top rail D is the eyebolt or pulley d, which is situated centrally between the jambs.

To the sides of the window-casing are pivoted the ends of the arms f and g of the rectangularly-bent shade-frames F G, respectively, the arms ff being suitably pivoted to the jambs at points below the arms g g, so that the frame F is at a suitable distance above the sill and the frame G at a suitable distance below the top rail D.

II is the web or cloth of the sun-shade, having its upper edge attached to the frame G and its lower edge to the frame F, the side portions of said web being attached at their upper and lower edges respectively, to the arms of the said frames, so that the window can be well shaded when the webis drawn up.

I is a cord secured at one end to the center of the frame G, and passes thence through the eyebolt (Z, whence it depends toward or to the sill.

K is a similar cord secured centrally to the frame F, passing upward and through the said eyebolt and depending therefrom.

In operation both cords I and K may be drawn down to the fullest extent, so that the upper portion of the web maybe drawn against the top rail of the window-frame and the lower part of the web drawn against the upper part; or the cords may be drawn up, more or less, according to the degree of shade necessary. When the cord K is drawn up, more or less, raising the frame G, and the cord I not drawn u p,the warm air can pass out over the top of the web of the shade and establish a ventilating-draft in the room. The cords I and K, when the upper and lower edges of the web have been raised, are wrapped around the cleats h, c, or c to keep the shade in proper position. It will also be observed that the cloth covering II is applied to the arms g of the upper jointed frame by means of sleeves g, loosely applied, so that these sleeves are free to slip on said arms toward and from the connecting-bar of the frame G. The side attachments of the cloth H will slide downward and assume the position shown in Fig. 3. It is therefore obvious that when. the frame G is depressed the loosely-sliding sleeve 9 will allow the upper end of the sides or cheeks of the awning-cloth, which I now letter H, to slide down and fold compactly about the transverse bar 9 of the upper frame. This position of the awning is very clearly shown in Fig. 5. In this position of the parts the lower frame may still be held as shown in Fig. 3 5 but the entire upper area included between the frame G and the window-frame below the lintel D will admitlight into the room, the lower portion of the awning above being used as a shade. By a further manipulation of the lower frame F, so as to bring it within the vertical plane of the window-frame and then dropping the upper frame G, the two means, substantially as described, whereby awning-frames Will closely and compactly fold the upper and lower frames may be operated together. independently, as and for the purpose set Having described my invention, I claimforth. 5 In an awning of the class described, in coln- In testimony whereof I affix my signature in 15 bination with thelowerhingedfrzune F fend presence of two witnesses. the upper frame G, hinged at a fixed point, of the awning-cloth H, having its cheeks H lVitnesses: secured to the upper hinged frame Gby loose THos.
