AWNINGr.

Application led. October 18, 1924. Serial No. 744,351.

This invention relates to improvements in awnings and particularly to awnings which are lowered and elevated by means of a cord. One object of the invention is to arrange such an awning and its support so that it can be dependably operated under all conditions, and another object is to simplify the mechanism for supporting and operating the awnings. Other objects of the invention will be apparent from a consideration of the accompanying drawings and the following descrip tion thereof Of the drawings Fig. 1 is a front elevation of an awning and the operating mechanism thereof; Fig. 2 is an enlarged side elevation of the awning; Fig. 3 is an enlarged detail elevation of the operating mechanism and support of the awning, showing in dotted lines the relative positions of the parts when the awning is being raised yor lowered; Fig. 4 is a side elevation of a modification of the awning and support; and Fig. 5 is another modified form of the operating mechanism.

The awning, as shown by the drawings herein, is fixed to the window sill by means of a bracket 11 and guide rods 12, one end of each rod being fixed to the sill and the other end being held in by the lugs 13 of the bracket 11. Slidably and rotatably mounted on the rods 12 are brackets 14 to the flanges 15 of which are pivoted bars 16, the outer ends of the bars 16 supporting a rod 17 to which the lower end of the awning fabric 18 is fixed. From the rod 17 the fabric 18 normally extends upwardly and towards the window and passes'under a rod 19, supported by the brackets 2O which are ixed to the window sill. The fabric then passes upwardly and is fixed to a roller` 21. rlhe roller 21 is rotatably mounted by means of brackets 22 hxedto the window sill.` A reel 23 is fixed to, and concentric with, one end of the roller 2l, and an operating cord 24 has r one end lined to the reel 23 and is wound around the reel sutiiciently, and then passes directly downwardly to a point where it may be conveniently reached by the operator of the awning. The weight ofthe bars 16, the rod 17, and the awning fabric 18 will tend to rotate the roller 21 and thus to wind up the cord on the reel. But if the lower end of the cord is .fixed in any manner the awning will remain supported, and may be thus maintained at any desired position. Any suitable means may be used for holding the lower end of the cord. I prefer to pass it around a pulley 25 supported by a bracket 26 and then to a cleat 27 about which the cord may be wrapped.

I also provide means for firmly holding each of the bars 16 against upward moven ment when the awning is in place. These means comprise a pawl 28 pivoted to each of the bars 16. These pawls are adapted to coact with teeth 29 fixed to the flange 15 of the bracket 14. When the awning is in the position shown by Fig. 2, it is obvious that the ends of the bars 16 can not be pulled upwardly; hence, by pulling tightly on the cord 25 the awning will be held firmly in place, and the particular angle of the bars 16 will depend upon the particular tooth 29 with which the pawls 28 coact.

In order to suitably operate the bars 16, in adjusting the position of the awning, or to remove the entire awning from the front of the window, the shape of the pawls 28 is such that when. the cord 24 is loosened and the bars 16 are turned downwardly, the pawls 28, after passing away from the teeth 29, will turn downwardly as indicated at 30 in the 3. The bars 16 may then be pulled upwardly to a vertical position. When in this position the force of gravity acting on the pawls will turn them to the position indicated by Fig. 3. lf now the cord 24 is again loosened the force of gravity will rotate the upper ends of the bars 16 downwardly and the pawls will take positions such as are indicated by the full lines in Fig. 3; and, obviously, when the vpawls thus coact with any of the teeth 29 the bars will be held from upward movement by the pawls; so that the bars may be held at any angle which may be desired so long as the pawls coact with the teeth. It is usually desired to hold the bars at substantially right angles in the position indicated in Fig. 1, but the outer ends of the bars 16 may be supported materially higher 100 if desired.

In order to remove the entire awning fab ric awa-y from in front of the window, the brackets 14 are slidably mounted on the rod 12, and, by pulling downwardly on the cord 24 after the bars 16 are substantially vertical, the awning fabric will be rolled up on the roller 21 until the ends of the rods reach the roller, when, if the various parts are properly proportioned, the awning fabric will be entirely above the window. From this position, in order to replace the awning, it is necessary only to release the cord 24 and the weight of the Various parts .will force the brackets 14 downwardly until they rest upon the flanges 13, when thebars 16 will rotate outwardly and downwardly to the desired positions.

In order that the bars 16 will rotate. downwardly from the elevated positions the arrangement is suoli that these ,bars never reach a vertical position; and to prevent'this any suitable means maybe taken. I prefer to provide lugs 11 fixed at the back of the pawls 2S, and these lugs andthe pawls themselves strike against the brackets 1-1 when the arms 16 have been raised sufliciently.

In order to prevent any improper coaction ot the pawls 2S with the flanges 15 or the teeth 29, as the awning is being lowered, I provide lugs 42 extending upwardly from the flanges 15, so that, as the arms 16 are lowered, the ends of the pawls 28 will strike upoirthe lugs 42' and prevent any possibility of the pawls striking on the upper' surfaces L13 of the flanges 15 or the upper teeth and thus preventing downward movement of the bars 16.

Fig. i illustrates a modification of my awning support. In this case the brackets 50, which take the place of the sliding brackets 14, are permanently fixed to the window sill, the rods 12 are dispensed with.

By operating' the cord 51 the bars 52 may be elevated or lowered in the'same manner as has been described herein with referenceto the bars 16. The pawls 53 coact with teeth in the same manner as the coaction of the pawls 2S with the teeth 29'when the barsr52 are elevatedA to substantially the vertical position, however, the awning as a whole can not be elevated, as is the case with the'awning illustrated in Fig. 1. A further modification is to increase the length of the bars 52, and, if desired, the outer ends of those bars will rise substantially to the roller 55 and the awningmay thus be removed cntirely or substantially from in front of the window. As a further modification I'pro- 'vide means for varying the length of the bars 52. rl"hese means comprise sockets 56, which are pivoted to the brackets 50, `and sockets 57 which are fixed to the rod 58.

rIlh'elength oit the bars may thcnbe varied asdesired by mounting a rod or pipe 59'in the sockets 56 and 57. In order tiovary the length of the bars 52 it is necessary only to insert'in the sockets bars 59 of the desired length. A

5 illustrates a further modification which can be used with either type of mechanism. This comprises, a toothle'ss surface 60` onthe flange 61 with which thepawl 62 pivotally connectedto 'said 'arm and normally extending inwardly and upwardly `from its'pivoted end, holding means mountedyon said bracket with which the end ot said pawl is normally engaged, and from which vit 'is' disengagedby the loi'vering oi the arm, said paw] being arranged to be forced downwardly by gravity when so disengaged from said'holding means.
