WINDOW-SHADE STRUCTURE AND VENTILATOR THEREFOR.

Specification of Letters Patent.

PatentedMay 6, 1919.

Application filed November 13, 1918. Serial No. 262,341.

To all whom it may concern:

Be it known that I, GILBERT E. Losnn, a

citizen of the United States, residing at 1822 North Bouvier street, Philadelphia, in the county of Philadelphia and State of Penn-,

sylvania, have invented new and useful Improvements in .Window-Shade Structures and Ventilators Therefor, of which the following is a specification.

The invention relates to window shades or blinds, and to ventilating devices therefor, and has for an object, to provide a window shade structure and ventilating device in which the shade can be operated in the usual manner and the ventilating device operated independently of the shade or so arranged that the ventilatingdevice willbe in ventilating or non-ventilating positions whether the shade proper be in raised or lowered thereon.

position.

I am aware that various forms of shades and window ventilating devices have been used heretofore, but in the majority of the instances the ventilating attachment or device forms a part of-the shade or curtain,

wherein the lowering of the shade relative,

to the window sash will not expose the ventilating device or bring it into ventilating position, whereas the continued lowering of the shade will do so because of the fact that the ventilating structure forms an integral part of the shade proper, or is so rigidly attached thereto, so that when one is operated, the other must also operate. This has been found to be highly undesirable because when the shade is lowered to its lowermost extremity, the ventilating device must necessarily be exposed. I

In my invention I overcome these. defects by having the shade proper operated independently of the ventilating devlce although the ventilating device or structure is so arranged anddisposed relative to the window sash or shade proper that the effect to the observer is that of a shade with an ornamental border and thus the entire structure presents a more attractive arrangement than is ordinarily observed with the form of shade that is now generally used in connection with the window sash.

In the further disclosure of the invention,

drawings, forming a part of this specification, in which similar characters of reference denote corresponding parts in all views, and inwhich Y Figure 1 is a front elevation of the shade and curtain of the ventilating device, the ventilating device being in non-ventilating position, the side brackets not being shown in this view.

'Fig. 2 is a similar view with the ventilat ing device, however, shown in ventilating position.

Fig. 3 is an end view of the structure shown in Fig. 1.

Fig. 4: is an end view of the structure shown in Fig. 2.

Fig. 5 is. a-fragmentaryelevation of my device,'showing a bracket construction and themanner of mounting my invention Fig. 6 is a horizontal sectional view taken on the line 66 in Fig. 5.

Fig. 7 is a viewof the bracket by itself, looking into the same, and-- Fig. 8 is an elevation of a modified form of bracket. i

Referring more particularly to the views, the numeral 10 indicates a shade or blind, as the case may be, which is of the ordinary construction made inthe same manner as the shades that are generally employed on window or window sashes, the mentioned shade being mounted upon a roller 11 of the usual construction and which therefore, is what is ordinarily termed a sprin roller, the latter having the shade normally wound thereon with the usual studs'12 of the shade roller mounted ,in'suitable brackets which will be more particularly described hereinafter. The shade 10 also carries the usual shade cord 13, and an ornamental or suitable form of ring or holder 14 whereby the shade can be conveniently raised or lowered.

A second superposed roller 15 is employed, being similar in every respect to the roller 11, and therefore being provided with the usual studs 16, this roller 15 being also of the well-known spring variety. ound upon the roller 15 and having its upper end suitably secured thereto is a ventilating curtain 17 having series of openings 18 therein, which are preferably covered with the cloth or wire mesh indicated by the numeral 19, provided for the purpose of excluding flies, mosquitoes, and other insects from the room.

The ventilator curtain 17 depends, as

shown in Fig. 4, to connect at its lower edge border strips or curtains acting as a part of the ornamental fixtures of my structure, will enhance the appearance of the entire device and also prevent the general observer, whether he be in the room or on the outside, from seeing the lower roller 11. The inner border strip 21 has the usual cord 22 and handle or holder 23 provided for the purpose of raising or lowering the border and consequently also the ventilator curtain, an additional cord 22, being EtttiLCllGCltO one of the border strips and the cross piece 20 so as to relieve the border strips of the strain that ordinarily would result when the pull is exerted upon the cord 22.

As shown in Figs. 5, 6, 7, the structure.

described is mounted upon a plurality of brackets 2&, one being provided for each side of the sash. Each bracket is preferably formed of a single piece of metal to provide upper and lower bearings 25 for the studs on the upper and lower rollers, and these hearings have lateral attaching flanges 26 through which suitable screws are passed to rigidly securethe brackets to the sides of the window sash, each bracket further including a vertical guide portion 27, having a longitudinal slot 28 and of a triangular shape in cross-section, said guide portion being formed'between the upper and lower bearings 25. Referring now to Figs. 5, 6 it will be seen that the cross piece 20, at the ends thereof is provided with fingers or proections 29, which are shaped to conform to the sides of the guide portion therefore overlapping said guide portion and it will also be seen that the vertical end portions of the ventilator curtain 18 will pass through theslots 28 of the guide portions and ride up and down therein as the ventilator curtain is raised or lowered.

It will now be seen that when the structure described is assembled with the lower roller journaled in the lower bearings of the brackets and the upper roller journaled in the upper bearings of the brackets, that the vertical end portions of the ventilator curtain will ride in the guide portions of the brackets, and the whole structure being disposed in the window sash, it will be seen that whether the ventilator curtain is in nonven'-' it is desired to bring the same into ventilat-' ing'position, it is only necessary to exert a pull upon the cord and

holder

22, 23,'thus causing the border strips to be drawn down and resulting in the unwinding of the flexible ventilator curtain from its roller to expose the ventilating openings thereof at the top of the window, the upper sash of which has been previously lowered so that fresh air can readily enter the room. It should be particularly noted that by having the vertical end portions of the ventilator screen operating in the guide portions of the brackets, that the tendency of the ventilator screen to flap and be noisy is overcome, it being well-known that in the use of the ordinary window shade when the window is raised from the bottom or lowered from the top, the result usually is a flapping of the shade that is decidedly an inconvenience and may result in the tearing or mutilation of the shade. With my device-this is overcome by having the ventilator curtain arranged so that it would be drawn in to ventilating position immediately adjacent the upper part of the sash, and thus there is less tendency of rain, sleet or snow to enter the room than there would be if the ventilator were at the bottom ofthe sash, further providing proper ventilation by having ventilating openings at the top.

In 1 ig. 8 I disclose a modified form of bracket and which is preferably employed in cases Where the spring roller is not of the usual construction involving a pawl and ratchet wheel construction, but wherein the latter is dispensed with and the spring of the roller continually exerts a pull to wind up the ventilator curtain thereon. Therefore the form of bracket shown in Fig. 8 and indicated by numeral 27 has a plurality of opposed projections 30, formed integrally with the body of the bracket and near the upper end ofthe guide portion, the lower end of the latter on one side being formed with a notch 31. With this arrangement the projecting fingers 29 will bear against and be held by the projections 30 to prevent the ventilating device from entirely winding up upon its roller, and when a pull is exerted on its cord to bringv the ventilator curtain down, oneof the fingers on each end of the cross piece will fit into the notch 31 on each bracket when the ventilator curtain is unwound from the roller to be brought in the ventilating position, and upon releasing the pull on the cord the ventilator curtain will be held in this position.

From the foregoing description it will now be clearly seen that the device described is so arranged that the ventilator curtain can be operated independently of the usual shade, and that the shade can be operated independently of the ventilator curtain, although it must be remembered that a relation exists between the ventilator curtain and the shade because the border strips, forminga part of the ventilator structure, provide a means for inclosing the shade roller and are a necessary part of the construction in order to bring about the desired result and orna mentality.

By employing brackets of the character I have described, it is possible to bring about a standard form of construction which will be applicable to various kinds of windows and which will be a commercial asset from the standpoint that it will not require the use of skilled labor to mount the entire de vice upon a standard form of window sash, the invention consists of few and simple parts that can be readily assembled in proper relation to each other to bring about the desired result.

It will be understood that I do not limit myself to the particular disclosure in the drawings and description herein; that various slight changes may be made without departing from the spirit of the invention and that the scope thereof is defined in the appended claims.

It will be further understood that my form of ventilating device, can be used with any form of standard shade and therefore my ventilating device can be applied to a. window sash which has previously been equipped with a shade, although of course it will be understood that a particular form and kind of shade can be cut for my particular kind of ventilating device, if desired. However by providing a device that can be applied to window sashes that are already equipped with shades it will be apparent that it is only necessary to provide the ventilator curtain and the component parts thereof in sizes suitable to the usual standard sizes of window sashes and the shades that have been previously mounted thereon.

Having described my invention, I claim,

1. A window shade structure and ventilator therefor, comprising a movable shade for the window, a movable ventilator curtain for the window in superposition to the window shade, the said curtain being movable independently of the shade and the shade being movable independently of the curtain, said ventilator curtain being movable into Or out of ventilating position and border curtains movable with said ventilating curtain and overlying the window shade, whether the ventilator curtain be in or out of ventilating position.
