AWNING-FIXTURE.

Application filed October 30, 1916.

To all whom it may concern:

Be it known that I, Davn) H. HARNLY, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Awning-Fixtures, 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 more particularly to those which are wound upon a spring roller. The object of the invention is to provide an improved fixture for holding the awning in extended position, the improvement residing more especially in a construction which permits an automatic release of the awning from the fixture when the awning is to be raised.

In the accompanying drawings,

Figure 1 is a perspective view showing an awning equipped with one form of the improved fixture.

Figs. 2, 3 and 4 are front elevations of the improved fixture showing the movable part of the same in different positions, the associated part of the awning rod being shown in section and a further position of the movable part of the fixture being shown by dotted lines in each of the said views.

Fig. 5 is similar to Fig. 2, but shows a difierent form of the improved fixture, and

Fig. 6 is a side elevation of the parts shown in Fig. 5.

The drawings illustrate the use of the improved fixture in connection with an awning which is wound upon a spring roller 10. This roller is of Well known construction and comprises the usual concealed spring 11. It is shown as being extended between the two sides 1213 of the window frame near the top of the window. The awning 14: is also of a familiar form, having its lower end mounted upon the cross piece 15 of an arch 16. The two ends 17-18 of the arch 16 slide in grooves, as 19, in a well known manner.

When the awning 1 1 is completely raised the arch 16 occupies an upright position in the plane 'of the window frame with the cross piece 15 of the arch extending along the underside of the roller 10. When the awning is lowered the ends 1718 of the arch 16 slide in the grooves, as 19, until the lower ends of the said grooves are reached. The cross piece 15 of the arch then swings outwardly to support the awning in Specification of Letters Patent.

extended position. If desired a guide rod 20 may be extended between the two sides 1213 of the window frame in front of the awning to confine the extension of the awning to that part of the same which is below the said rod. The awning 11 may also be drawn down to a position in which the arch 16 is inverted at the lower end of the window and the entire awning is extended in the plane of the window. This last mentioned position of the awning serves for darkening the room.

The improved fixture provided by the invention is employed for maintaining the arch 16 in the horizontal position illustrated in Fig. 1. The form of construction illustrated in Figs. 1 to a inclusive may also be used for maintaining the arch 16 in a downwardly inclined position indicated in Fig. 3. The last mentioned position of the arch 16 corresponds to a depressed position of the awning for shutting out a low sun without darkening the room. As the spring roller 10 serves to raise the awning, the improved fixture is only required to resist upward movement of the arch 16. i

In carrying out the invention a notched plate, as 21, (Figs. 1, 2, 3 and 4:) or 22, (Figs. 5 and 6) is mounted to swing across the path of each of the end portions, as 17-18, of the arch 16. As shown, each of the plates 21 or 22 is supported in front of the corresponding side 12-13 of the window frame at substantially the same elevation with the lower end of the groove, as 19. For this purpose a bracket 23 having an inturned outer end 24L, is secured against each of the side members 12-l3 of the window frame to project outwardly therefrom and each of the plates 21 or 22 is pivotally secured against the end 24 of the corresponding bracket 23.

I11 the form of construction illustrated in Figs. 1 to a the pivot, as 25, is located between the ends of the corresponding plate 21 and is only sufficiently removed from the mid-length of the plate to permit the plate to assume a definite position by gravity. WVhen so mounted the plate 21 is preferably provided with notches 26 and 27 at its upper and lower ends respectively. In the normal position of the plate 21, the notch 26 opens upwardly at one side of the path of movement of the corresponding end portion, as 17, of the arch 16. Under these circumstances the upper end portion, as 28,

of the plate 21 extends over the inner end of the notch 26 in the form of a hook for engagement with the arch. On the other hand, that portion, as 29, of the plate 21, forming the other wall of the notch 26, extends inwardly beyond the end of the hooked por tion 28 and provides an abutment for engagement. by the corresponding end portion, as 17, ot' the arch for swinging the plate during downward movement of the arch. In the gravity supported position of the plate 21, the notch 27 faces downwardly and is located directly in the path of movement of the corresponding end portion of the arch 16. Under these circumstances the notch 27 is entered by the corresponding end portion, as 17, of the arch, during the upward movement of the arch, to turn the plate for permitting the arch to pass by the plate.

In the form of construction illustrated in Figs. 1 to 4 the plate 21 may also be formed with a third notch, as 30. As shown, the notch 30 faces inwardly when the plate 21 occupies the position illustrated by dotted lines in Fig. 2. It follows that if the arch 16 is lowered to a position in which its end portions 17-1S have cleared the parts 29 of the correspondii-ig plates 21, but have not been cleared by the adjacent sidewalls, as 31, of the notch 27, the end portions of the arch will enter the notch 30 when the arch is released. This position of the parts is illustrated by full lines in Fig. 3, the arch being held in a depressed position providing a lowering of the awning for obscuring a low sun without darkening the room. For releasing the arch from this position it is only necessary to lower the awning through a sutficient distance to permit the end portions 1718 of the arch to enter the notches 27 of the corresponding plates 21. Upward movement of the arch resulting from the winding of the awning upon the spring roller 10 will. then serve to rotate the plates 21 to the position indicated by full lines in Fig. 1, thereby permitting the arch. to pass by the said plates.

In the form of construction illustrated in Figs. 5 and 6, the pivot, as 32, by which each plate 22 is secured against the end portion 2-l of the corresponding bracket 23, is located near the top of the plate. Under these circumstances the plate 22 has but one notch, as 33, and this notch faces inwardly in the normal position of the plate. As shown, that part as 3st, of the plate 22 which constitutes the bottom wall of the notch 33, projects inwardly beyond the part 35, forming the upper wall of the notch, and the part 35 is curved downwardly to form a hook for engagement with the corresponding end portion, as 17, of the arch 16. This form of construction requires that the swinging movement of the plate 22 should be limited in one direction, as by the formation of a stop lug 36 upon the plate for engagement with the bracket 23. This form of construction also requires that the lower margin, as 37, ot the plate 22, should be beveled for cam engagement with the corresponding end portion, as 17, oi the arch.

In using the form of construction illustrated in Figs. 5 and 6, the awning is maintained in extended position if lowered only far enough to bring the end portions, as 17, of the arch 16, in front of the mouth of the notch 33 in the corresponding plate 22. During downward movement of the arch to this position the plate 22 is swung outwardly by a cam engagement'ot the adjacent end portion, as 17, of the arch, with the margin of the plate above the notch 33. If the downward movement of the arch 16 is arrested when itsend portions, as 17 are each in line with the mouth of the notch 33, the plate 22 will be returned by gravity to enter the end portion, as 17, of the arch in the notch. On releasing the awning the hooked 7 wall 35 of the notch becomes engaged with the corresponding end portion, as 17, of the arch for maintaining the awning in extend.- ed position. When it isdesired to raise the awning, it must first be lowered to a position in which the end portion, as 17 of the arch, may be engaged with the oblique margin, as 37, of the plate 22. On being released from this last mentioned position, the winding of the awning upon the spring roller 10 serves to raise the arch 16 quickly and the plate 22 is swung outwardly to permit the adjacent end portion, as 17, of the arch, to pass by without entering the notch 33.

In both of the forms of construction illustrated'in the drawings the swinging of the plates 21 or 22 is entirely automatic; It is accordingly unnecessary to reach through the window for the manipulation of these plates and no cord or other releasing device, extending through'the window, is required. l
