DAVID H. HARNLY, OF CHICAGO, ILLINOIS.

AWNING.

Application filed October 6, 19-21. Serial No. 505,725.

To all whom it may concern:

Be it known that 1, DAVID H. HARNLY, a citizen of the United States, and resident of Chicago, county of Cook, and State of 11- linois, have invented certain new and useful Improvements in Awnings, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates: to awnings and has for its object the provision of an improved device, which, while of exceedingly simple construction, is capable of use in a plurality of desirable positions, is readily applied to and removed from the window and when furled, occupies a positioned; the top of the window whereby the entire window opening is unobstructed. A further object is to provide fixtures which are readily secured in the window frame for firmly holding the awning in any adjusted position.

This application, is a substitute for and in part a continuation of my prior applications for patent on awning, Serial No. 411,100, filed September 18, 1920, and Serial No. 429,955 filed December 11, 1920.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which Fig. l is a, front elevation of a window with the improved awning applied thereto, the position of the awning being that which it assumes at the moment of being released;

Fig. 2 is a vertical section on line 2-2 of Fig. 1;

Figs. 3 and 4 are detail perspective views showing two different forms of one of the fittings;

Figs. 5 and 6 are each similar to 2. but show different positions to which the awning may be adjusted, part of the canvas being omitted in Fig. 5 to avoidconcealing some of the other parts;

Fig. 7' is a detail perspective view illustrating the manner in which the awning frame "is firmly locked against accidental displacement by the wind or otherwise when the awning is completely lowered;

Fig. 8 is a detail perspective view of a re movable hinge for the awning frame, and Fig. 9 is adetail perspective view of a detail of the canvas and rigging.

The canvas 10 of the awning is supported by and furls upon a spring roller- 11, the

same being of usual construction and preferably equipped with the customary manually controlled pawl (not shown) designed to permit the roller to run free at all times when in puse, but to prevent unwindin of the spring when the roller is removed t rom the window. As shown, the roller 11 is mounted at its opposite ends in fittings 12 and 18, one of which is slotted as'usualto permit the roller to be put up and taken down exactly as is done with window shades.

To extend theawning, when lowered, the cross bar 14 of a bail-shaped frame is passed through a hem at the end of the canvas 10 and the arms 15 ofsaid frame are pivotally supported to permit the frame to swing outwardly away from the window. As shown in Figs. 1, 2, 5, 6, 7 and 8, the inner ends of the arms 15 are pivotally mounted in fittings 16 applied to the blind stops of the window frame at about the level of the parting rail between the upper and lower sash. To permit complete removal of the awning from the window without detaching the fittings 16,.each of thesefittings, Fig. 8, may be formed to'provide a socket 29 to receive the headed and overturned end 26 of the corresponding arm 15. Under these circumstances each fitting 16 also preferably includes a pivoted latch 27, which swings over the end of the arm to prevent accidental displacement of the same from the fitting. In using the form of construction illustrated in Fig. 4 the arms 15'of the awning framewill preferably each be formed with an eye (not shown) atits inner end, the fitting shown in Fig. 4 being provided with an integral apertured lug 34 through which a pivot pin (not shown)- for entering said eye may be introduced.

In carrying out the invention the arms 15 of the awning frame are bent intermediate their ends to provideelbows, as 17, which engage the window frame below the fittings 16 whilethe cross bar 19 is located at a substantial distance outwardly in front of the window. For; cooperation with the frame in adjusting the awning to different positions and'for locking the frame in its lowermost position, a stiffening rib or batten 19 is extended across the canvas 10 at a distance from its lower end preferably substantially equal to the length of the arms 15 beyond the elbows 17. Q

In order that the batten 19 will not interfere with the winding of the canvas upon'the extent that the unfurled part of the canvas above the batten extends in a substantially vertical plane in front of the upper part of the window while the part of the canvas between the batten and the cross bar 1d of the awning frame is inclined and provides a hood over the lower part of the window. For this purpose the pull cord, as 20, which serves for drawing the canvas from the spring roller 11 leads to the batten 19 rather than to the end of the canvas. As bending of the batten is to be avoided, the cord 20 is attached thereto through a bridle 22 which connects with the batten'at two widely separated points. The curved form of the batten also materially resists bending.

When the canvas is completely wound up the spring roller 11, the bridle 22 and a part of the cord 20 are also wound upon the roller between the adjacent turns of the canvas, Pulling the cord accordingly serves to lower the awning although the cord is not attached to the extreme end of the canvas. in this connection it will be observed that the bent form of the arms 15 of the awning frame insure that there will be a sufficient over" hang of the frame in front of its pivotal connection with the fittings 16 to cause the frame to fall by gravity from its upright po sition whenever the canvas is drawn from the roller 11 by the cord.

The position of the awning illustrated in Fig. 6 is obtained by pulling upon the cord 20 until the canvas 10 has been lowered to the extent desired where it is held against the winding effort of the roller 11 by the cord. For this purpose the cord will preferably be fastened at the bottom of the window, as upon a cleat 23 which may be applied to the window sill, outside of the sash. If desired a pulley 29, about which the cord turns, may be provided upon 'the sa mounting with the cleat 23. in this pn i tion of the awning, weight of the aw frame is relied upon entirely for tensioniii the extended part of the canvas.

Upon further lowering the canvas the elbows 1'? of the arms 15 engage the window frame, as in Figs. and 7. Since, when the awning is used at all in stormy weather, it will customarily be employed in this position, it is desirable that provision be made for firmly holding it against being raised. by the wind or the like. As shown, the batten 19 is made of such length that its ends 28 project beyond the canvas at each side to overlie the arms of the awning frame and downwardly and outwardly facing hooks 30, secured to the window frame below the fittings 16 at a distance slightly less than the length of the arms 15 above the elbows 17, are provided for receiving the projecting ends of the batten and urging the batten inwardly upon the said arms of the awning frame when the elbows 17 are engaged with the frame of the window. In this manner the awning frame is securely locked in position and the canvas 10 is held taut and prevented from flopping inthe wind.

in the form of construction illustrated in Figs. 1, 2, 3, 5, t5, and 7, the hooks 30 are formed upon fittings 31 which are applied to the blind stops of the window below the fittings 16. To prevent the engagement of the projecting ends of the batten 19 with the hooks 30 when the awning is to be raised, the fittings 81 preferably each includes a hinged gate piece 32 designed to close the hook opening when it is lifted by the batten, as in Fig. 2. To prevent the batten sliding over the end of the gate piece 32 before the gate piece has been lifted to a sufficient height to close the hook opening, the lower edge of the gate piece is preferably notched, as at 33. In order to release the awning from the locked position it is only necessary to pull upon the cord 20, causing the batten 19 to slide over and beyond the inclined upper edges of the gate pieces 32. On now slackening the cord the spring roller- 11 will cause the batten 19 to engage the notches 33, thus swinging the gate pieces upwardly for guiding the batten 19 clear of the hooks 80.

In the form of construction illustrated in Fig. 4, the hook 530 is formed upon a fitting which also includes the bracket lug 34 to which the corresponding arm 15 of the awning frame is pivotally attached. The fitting 35 includes a stationary part 36 for guarding the open end of the hook 30. When this form of construction is used the projecting ends of the batten become engaged with the books 30 only when the awning las been lowered to a position in which the batten just clears the ends of the hooks. If the awning is further lowered and then released, the guards 36 will so deflect the bat ten during its upward movement as to prevent its engagement with the books. It follows that to release the awning from its locked position, it is only necessary to pull upon the cord 20 until the batten is lowered beyond the guards 36 and then release the cord in the same manner as when the form of fitting illustrated in Fig. 3 is used. With either form of fitting, the ends of the batten when engaged with the hooks 30 are urged inwardly upon thearins 15 of the awning frame due to the spring tension of the roller 1.1 and the downward and forward inclination of the hooks. There is accordingly no llll Czi

opportunity for any movement of the awning frame under the influence of the wind or from any cause when it occupies its said locked position.

The awning is suitable for use at any time of the day. At noon, when the sun is hot and its rays directed almost vertically downward the canvas is only partly lowered and is held out from the window by the arms 15, as'in Fig. 6, thus allowing free circulation of air beneath the awning. Later in the day, when the rays are more nearly horizontal, but when the heat is not so intense, the awning is lowered to the position shown in Fig. v5, where the upper part of the canvas is closely drawn against the window, while the lower part only is sloping.
