Application filed October 11, 1915.

To all whom it may concern:

Be it known that I, EDWARD G. PFAN- SCHMIDT, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Awnings; and I do hereby de clare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and i to the numerals of reference marked there on, which form a part of the specification.

My invention relates to awnings, of that type wherein the awning fabric is wound upon a roller at the top of the window, and has for its object to provide certain improvements in the construction and operation of the same, whereby the device may be applied to a window frame with a minimum of effort and whereby the arrangement will be such that the awning may be manipulated from the interior without the necessity for raising or lowering the sashes or the screens which may be in position.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a front elevation of the assembled awning parts of one side of the window frame.

Fig. 2 is an edge view thereof.

Fig. 3 is a sectional view on the line IIIIII of Fig. 1, with the parts in elevation and parts omitted.

Fig. i is a detail view showing the offset extension brace.

Fig. 5 is a conventional exterior view with a window equipped with an awning embodying my improvements, showing the awning rolled up into a position out of use.

Fig. 6 is a view similar to Fig. 5, with the awning lowered and extended for use.

As shown on the drawings:

Reference numeral 1, designates the wall of a building having a' window aperture therein for mounting a window frame 2, within which are slidably mounted in any suitable manner the usual upper and lower window sashes. Removably mounted in said window frame 2, outside of the sashes, is a full length screen, comprising stiles 5 and 6, a top rail, and a bottom rail 8, said stile 5, and bottom rail 8, being cut away to permit the screen to fit over a locking or ad justing mechanism 9, rigidly secured in the Specification of Letters Patent.

' integrally Patented July 3, 191%.

Serial No. 55,154.

2, as clearly shown in Figs. 5 and 6.

Rigidly secured on the upper outer surface of the window frame 2, by means of screws, are long carrying plates l2 and 13, of any suitable type, on which are secured brackets 12 and 13, respectively. Said brackets are adapted to receive detachably journaled therein the gudgeons of a spring controlled curtain type of roller 14:, provided, with a small pulley or sheave l5, rigidly secured thereon to receive an actu ating rope or cord 16, having one end attached to said pulley to permit said cord 16, to be wound therearound, the other end of said cord extending downwardly to the bottom of the window casing 2, and passing through the casing 9, into the interior of the building for conveniently operating the roller. In order that said cord 16, may be prevented from winding up completely around the pulley 15, a ring or stop (not shown) is knotted in said cord 16, at a convenient point, and is adapted to strike an eye 17*, near the upper end of said attaching plate 12, through which the cord is trained.

The awning fabric is designated by reference numeral 18, and has one end thereof secured upon the roller 1%, which is adapted to receive the fabric wound thereon. Inserted through a hem on the lower end of the awning fabric is an oflset unbalanced U- shaped extension brace 19, the ends of which are pivotally mounted on pins 20, formed on sleeves 21. Said sleeves are slidably mounted upon guide rods 22, of square crosssection, which thus hold said sleeves rigid in all movements ably secured at each side of said window frame 2, approximately half way between the upper and lower ends thereof, on the plates 12 and 13*, are bracket plates 23, having integrally formed on the outer ends thereof tubular members 24:, bent to extend over and in front of the guide rods 22, and oppositely disposed from one another to support a cross brace rod 25, the ends of which fit into said tubular members. Said brace rod 25, is adapted to hold the upper portion of the awning fabric in the plane of the window frame when the awning fabric is moved upwardly or downwardly behind said brace rod.

The operation is as follows:

The attachment of the awning on a window frame is made an easy matter due to the fact that practically all of the parts are assembled on the plates 12 and 13 ready to be screwed on the window frame, thus obviating the labor and inconvenience of mounting the individual parts separately and assembling the same. The entire structure, after attachment on the window frame is exceedingly rigid due to the fact that said plates are not only secured at a. number of points throughout their length, but owing also to the transverse brace plates 26, at the upper ends of each of said plates and further due to the transverse brace rod 25, connected rigidly between the attached bars 12 and 13 With the window screen in position, as shown in Fig. 5, with the lower window sash 4:, raised for ventilating purposes, if it is desired to lower the awning from its retracted position as shown, it is unnecessary to move the screen from its position in the window frame, the only operation required being that of slightly pulling on the lower end of the adjusting cord 16, which extends into the interior of the building. This pull releases the cord from the looking or adjusting means, and by continuing the pull, the cord gradually unwinds from the pulley 15, turning the pulley and awning roller 14, simultaneously, thus unrolling the awning fabric 18, which is guided downwardly by the sleeves 21, sliding on the guide bars 22. When the awning has been lowered to such a position that the sleeves 21, strike the bottom of the guide bars 22, the brace 19, which is offset so as to be overbalanced, automatically pivots on the pins 20, said brace swinging outwardly drawing the awning fabric therewith. The brace rod 25, being positioned across the fabric holds the upper portion of the awning in a plane with the window frame, the lower portion of the fabric, however, taking an extended oblique position.

If it is desired to hold the awning in this position, it is only necessary for the op erator to engage the cord 16, with its locking mechanism 9. The action of the spring roller 14:, tends to pull outwardly and upwardly on the cord 16, which becomes caught, said locking mechanism thus ho1d the movement of the awning in that direc tion, and when the awning is being raised,- its upward movement is limited by the sleeves 21, contacting the upper end of the guide rods 22, or by the stop device, contacting with the screw eye 17 or other suitable means secured to the window frame 2, through which the operating cord 16, may be threaded.

It will, of course, be understood that the operation of the awning may be as equally well accomplished fronithe interior of the building when the windows are closed and when no screens are used, by mounting the locking mechanism on the bottom of the window frame underneath the window sash, and cutting away a portion of the bottom rail of the sash to fit oversaid mechanism.

I am aware that the details of construction may be varied through a wide range without departing fromthe principles of. this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

In an awning construction of the class described, carrying plates adapted to be secured upon and extending longitudinally of the sides of a window frame, each plate carrying a roller receiving bracket, a guide bar below said bracket having one end of'an. unbalanced extension brace slidably mounted thereon, and a bracket plate mounted in termediate the length of said carryingplate and adapted to carry one end of a cross brace rod.

In testimony whereof I have hereunto subscribed by name in' the presence of two subscribing witnesses.
