AWNING.

Appiicafrion inea Aprn 1e, 192s. seriar No. 102,378.

The object of my invention is to provide new and improved means for mounting awnings, and also for holding them in` normal extended position. Vith these objects in view my invention consists in the matters hereinafter described and pointed out in the appended claims. K v ln the accompanying drawing, vFigure 1 is a perspective view of an awning embodying the features of my invention and mounted in position for use, only part of the window-casing being shown; Fig. 2 is a detail side view with parts broken away; Fig.V 3 is a detail frontview of the frame-fixture with parts of the frame in section on the line 3-3 in Fig. 2; and Fig. 4 is a detail sectional viewon .the line4-4'in Fig. 2.

The reference numeral 1 .indicates a spring-roller mounted in suitable brackets 2 secured upontlie outside of a windowcasing 3, usually at or near the line whereV the upper and lower sashes meet. The awning-cloth, consisting of a suitable length of canvas or other material, is connected intermediate its ends to the roller so that its upper and lowersections 4 and-5l will wind thereon. The lower section 5 is attached at its free end to the cross-piece of a bowed metallic frame-6, which is pivotally mounted at its endson the window-casing, andthe upper section 4 has a head-rod 7 to which an operating cord 8 is connected and passed over one or more pulleys 9, according tov whether it is extended down on the outside ofthe window or through the window-casing into the room.k The freeend of the cord may be suitably fastened either inside Vor outside the window to hold it in any desired position. Vhen the cord is drawn up the upper section 4 of the awning-cloth is extended or drawn upwardly tothe position shown in Fig. 1, the roller is revolved to place its spring section 5 of the cloth, and the frame 6 swings down by gravity to its extended position. lVhcn the cord is released the spring-roller automatically winds up thesections of the awning cloth to withdraw them from their extended positions and to swing the frame 6 up to positionalongside the window-casing below the roller. v

The frame Gis detachably securedto the window-casing by devices which permit it to be attached and detached without swinging the frame down below its normal extended position. 1n this type of awning as hereunder tension andunwind the lower tofore constructed hooks on the free ends of the frame engaged supports on the'casing, and in order to prevent disengagement of the hooks by the wind blowing the. awning upwardly it was necessary to extend or prolong the ends of the hooks around their supports, and consequently the hoolrs'conld be engaged thereon only when the frame was swung down below its normal extended position to permit the hooks to pass onto their supports from above. This is objectionable as it requires unrolling the awning-material which *isy then cumbersome and difficult to handle.L I obviate this objection by providmgthe frame 6 with endeyes or loops 10 which pivotally` engage opposite pintles 11 extending laterally from brackets 12 on thev casing.V The vfree ends of the pintles are reduced, and gravity latches 18 of approximately the same diameter as the pintles arepivoted thereon.intermediate their ends but offset from their centers as shown at 14;

when the latches are turned to align with the pintles theloops 10 may be easily slipped on or' off'the latter, and when the latches are releasdthey will turn by gravity to position tobloclr the loops and holdthem on the pintles. This construction simplifies the in-v stallation and removal ofthe awning, as it may be put up or taken down while thek cloth is wound on the roller and the frame is in one of its normal positions.

The frame 6 is held in its extended position by a friction lock` which has sufhcient grip to prevent the lower section of the awning being blown upwardly by the wind,

but wlnch readily yields to the, superiorv strength of the spring of the lroller when the cord is released to permitthe latter to revolve. In the form here shown, annular metallic collarsl are slidably'mounted on the side arms of the frame G, and each collar is provided with upwardly projecting ears 16 in which one end of a link 17 is pivoted, the other end ofthe link having a downwardly'opening hook A1,8 to vengage the iook cross-pin 19 of a jaw-hinge i2() on the casing Y above the bracket 12. Each collar is provided with a chamber in which a friction ball 21 is located and held by an expansion spring 2Q in contact with the associated side arm ofthe frame 6, which is provided with a recess or notch 23 so located that the ball engages it when the frame is in its extended position. inplace by a cap 249 and the pair of springs Each ball and spring are heldV Ii i) i'or each :trame is ot less strength than the roller-spring. lVhen the traine and awning` are extended by the cord 8 the balls engage the notches and hold the lower section 5 against 'flappingg or being blown upwardly by the wind. 'frvhen the cord is released the superior strength ot' the roller-spring overcomes the resistance of the relatively weaker springs 22 and the roller winds up the awning' and swings the trame G upwardly. The links move the collars inwardly and outwardly on the sides ot' the iframe as tlie'latter swings on its pivots.

The pivotal bracket l2 and jaw-hinge 2() tor each side ot the `trame are mounted in line on a base which is screwed to the window-casingg each base and its bracket and jaw-'hinge constitute a unitary fixture on 'which oneY side ot the traine G and its associated' link 1T are detachably supported, andall' these parts can be 'positioned by merely engaginT the hooks 1S with their pins i9 and the eyes 10 with their pintles Il, and can be removed by merely disconnecting` .the same. Both operations can be accomplished with the awning-cloth wound on its spring-roller. rl`h`c .tixtures provide a permanent assembly 'lor each pair of brackets and jaw-hinges, it being understood that the construction and arrangement ot the various parts are the same on each side of the awning.

I claim:

l. In a device of the class described, an awning, a swinging' iii-ame therefor pivotally mounted at its ends on a window-casing and having` a recess in oney oft its arms, a collar slidably mounted on said arm, a link pivotally connected to the collar and casing, a pressure member in the collar in line with said recess when the trame 'is cxtenoed, and

a spring in the collar adapted to torce the pressure member into engagement with the recess.

2. In a device oli the class described, an awning, a swinging` iframe there lor pivotally mounted at its ends on a window-casine` and having` a recess in one olf its arms. :i collar slidably mounted on said arm and having al chamber in line with said recess when the frame is extended, a link pivotally connected to the collar and casing, a ball inthe chamber, and a spring in the chamber adapted to force the ball into engagement with the recess.

3. In a device of the class described, an awninpcomposed olf upper and lower sections connected to a spring-roller adapted to be revolubly mounted on a window-casing;` a. swinging trame connected to the :tree end ot said lower sectionv and adapted to be pivotally mounted at its ends` on the window-casing and havinga recess in one ot its arms, a collar slidably mounted on said arm, a link pivotally connected to the collar andcasing, a pressure member in the collar inline with said recess when the frame is extended, and a spring in the collar ot less strength 'than the springi in the roller and adapted to'iorce the pressure member into engagement with the recess.

fl. In a device of the class described, a swingingawning' trame having an eye, a collar slidably mounted on the frame, a link pivotally connected at one end to the collar and having a downwardly opening hook at its other end, means to yieldingly hold the collar in position on the trame when the latter is extended, and a unitary fixture foithe eye and hook ot the frame comprising a base, a pivotal support at the lower end of the base for the eye, and a pin at the upper end of the base t'or the hook.

5. In a device ol' the class described, a swinging awning` frame having an eye, a collar slidably mounted on the trame, a link pivotally connected at one end to the collar and l aving a downwardly openingT hook at its other end. and a unitary lixture for the eye and hook ot the trame comprising a base constructed to be mounted on a window casing', a lateral pintle at the lower end ot the base having a pivoted latch tor the eye, and a pin at the upper end ot the base for the hook.

In testimony whereof I hereto aliix my signature.

HENRY E. SMITH.
