WIND OUT-AWNING.

riosaoos.

To all wiiom it may concern:

Be it known that I, WI LIAM F. Kant rm, acitizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in VVindowis so designed that it can be manufactured at a low cost and installed easily.

Other objects and desirable features of my invention will be hereinafter pointed out.

Figure 1 of the drawings is a perspective. view 1llustrat1ng my improved window awning closed orraised; Fig. 2 shows the awning open; Fig. 3 is a vertical sectional view of a window provided with an awning constructed in accordance with my inven tion, the awning being closed; Fig. 41- is a similar view showing the awning open; Fig. 5 is an enlarged front elevational View of the awning rolled up; and Figs. 6 and 7 are transverse sectional views taken on the lines 6-6 and 77, respectively, of Fig. 5.

Referring to the drawings which illustrate the preferred form of my invention, A designates a roller which is journaled in brackets l and 2 that are connected to a window frame B at a point adjacent the up- .peredge of the top sash of the window. A

piece of fabric C is connected to said roller, and a pair of pivotally mounted arms 3 are provided for holding the lower edge of said fabric extended so as toform an awning for the window. The lower edge of the fabric C may be connected to the arms 3 in any suitable manner but I prefer to connect the fabric to a erosspiece 4 that joins the arms 3 together. A stationary cross-bar 5 is arranged at approximately the middle of the window frame so as to hold the upper'portion of the fabric Q in a substantially vertical position, as shown in Figs. 2 and 4, and thus cause the awning to start to slope Specification of Letters Iatent.

outwardly at a point adjacent the'gmeeting rails of the top-and bottom sashes, the crossbar 5 extendingztransversely across the fabric, as shown in Figs. 1 and 2, and being provided at its ends with inwardly projecting arms 6 that are permanently fastened by screws or other suitable devices 'tothe side members of-the-window frame B. The

arms dare-so arrangedrthat they will slide vertically when the awning is raised and lowered, and in thepreferred formvofmy invention'as herein shown, :each of the arm.-.

3 ispivotally' connected at'itsinner end to a sleeve or hearing 7 that 'isslidingly mount ed on a vertically disposediguide rod or track 8 which is-fastened at its opposite ends .to the'front'face of one of the side, pieces of the window'frame.

The roller A is provided with a winding spring 9 and a pawl sand; ratchet mechanism 10 ofwany suitable design for automatically winding the fabric onto the roller, andran 'operating'device 11 which preferably con sists of a-fiat tape or piece of webbing, is

connected at its upper-rend to" the roller so as to rotate the roller in an opposite direction to thatwhi'ch the'sprin-g rotates it,-forth"e purpose of tripping the'pawl and ratchet mechanism or for downwardly.

In order that the'awning may-be operated without raising the screen D'that extends acrossthe lower sash of thewindow, I arrange the tape oroperatin device '11 liottom rail of the upper sash of the window, as shown in .Fig. 4, and fasten a knob or cleatlO to the window frame B at a p'oint'inside of the screen so as to enable the'tapebrto be secured by wrapping it around said knob.

Any suitable kind of spring-operated roller A may be used for carrying. the fabric C, and any suitable kind of brackets may be used for supportingtheroller, the-break.

ets herein shown beingsimilar to those generally used for supporting the roller. of a window-shade except that the bracket 2 is provided with a pin 12 that prevents the trunnions on the end of the roller from jumping out of thefopen-ended slot in said bracket, as shown in Fig. 6.

To close or raise the awning, the operator simply pulls the operating device 11 downwardly far enough to trip the pawl and drawing the awning ISO roller to rotate the roller in the proper direction to cause the fabric to be wound onto same, .As the fabric winds up it'first pulls,

ratchet mechanism of the roller andthus permit the winding spring inside of the the arms 3 into an upright position and the continued upward movement of the fabric causes said arms to move upwardly into the position shown in Figs. 1 and 3, the upward travel, of said arms being arrested when the sleeves or bearings 7-, to whit the inner ends of the arms are connected, strike against the upper ends of-the' tracks 8. If it is desired to raise the awning only-partway, the operator grasps the tape 11 so as to arrest the movement of the roller A and thus cause the roller to be locked by the pawl and ratchet mechanism of the roller when the fabric has, moved upwardly the desired distance. To lower the awning the operator pulls the tape 11 downwardly so as to turn the roller A'in the opposite direction to that in which the spring rotates it, the arms 3 sliding downwardly on the rods-8 and also swinging. outwardly into the position shown in Fig. 4 after the crosspiece 4 at the lower edge of the fabric has passed the stationary cross-bar 5.

A window awning of the construction above described presents a neat and ornamental appearance, and when it is closed it does not detract from the appearance ofthe window owing tothe fact that the fabric is wound up into a roll which is arranged at the extreme upper end of the window open.- ing, as shown in Fig. 1. The awning can be raised and lowered easily without even raising the window screen, and as the roller comprises a pawl and ratchet mechanism that automatically locksthe roller when the rotary movement of the-roller is arrested, it is not necessary totie the operating tape to a cleat so as to securethe awning in adjusted position.

Another desirable feature ofmy improved awning is that the upper'portion of the window is shaded or protected when the awning is only part-way idownyand still another desirable feature is that the awning is of such simple construction that it can be manufactured cheaply and installed easily. Having thus described my invention, what I claim asnew and desire to secure by Let-v ters Patent is: a

1. A window awning comprising a springactuated roller arranged adjacent theupper edge of a window opening, a pawl and ratchet mechanism for locking said roller, manuall -Operated means for rotating said 6O roller so as to store up energy in the spring that actuates the roller, apiece of flexible material connected to said roller to form a shade for the window, arms which hold the" lower edge portion of said material extended, vertically disposed guide rods connected to the front face of the side pieces of the window frame, sleevesslidably mounted onsaid guide rods to which the inner ends of said arms are pivotally connected, said guide rods having portions which arrest theupward movement of said sleeves, and a ratchet mechanism, bearings arranged ad-.

jacent the upper edge of a window opening for supporting said roller, means for looking the roller in said bearings,'a stationary crossbar arranged transversely across the window openingat approximately the middle of same, vertically disposed tracks connected to the front faces of the side members of the window frame,slidable bearingson said tracks provided with pivotally mounted arms whose outer ends are connected together by an integral cross member, a piece of fabric connected at its lower end to said cross member and at its upper end to said roller and adapted to pass under the cross-bar at the middle of the window opening, and a flat tape connected to said roller and adapted to be wound up with the fabric for controlling the roller.

stationary cross-bar for holding the upper In testimony whereof I hereunto aflix my signature in the presence of two witnesses, this seventeenth day of February 1912.
