Specification of Letters Patent.

AWNING.

Patented Oct. 27, 1914.

Application filed March 4, 1914.. Serial No. 822,344.

To all whom it may concern Be it known that I, Hans lVnnwATI-I, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Awnings, of which the following is a specification.

My present invention relates to improve ments in awnings and is particularly designed to provide a simplified supporting frame for the awning.

The primary object of the invention is to simplify the construction and operation of window and similar awnings, by fashioning adjustable guide armsor brackets which are operable and. co-act with the awning as it is raised orlowered.

The invention consists essentially in certain novelcombinations and arrangements of parts as hereinafter set forth and pointed out in the appended claims.

In the accompanying drawings 1 I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure 1 is a sectional view through a window showing the application thereto of my invention. Fig. 2 is an outside view of the window of Fig. 1 with the awning fixtures attached. Fig. 3 is an enlarged view of one of the awning brackets or guide bars of the supporting frame. Fig. 1 is an edge view of Fig. 3. Fig. 5 shows an automatic locking device employed to hold the movable portion of the bracket in the extended position assumed when the awning is in operative position. Fig. 6 is an edge view of Fig. 5. Fig 7 is a diagrammatic view showingthe awning when in lowered posi- .tion.

In the preferred embodiment of my invention I employ two stationary brackets as l and 2 attached to theright and left sides of the Window frame 3 by means of the flanges or lugs 4 located at either end. These brackets are made in pairs and are duplicates, except that one may have a perforation, and the other an open slot as 5, as bearings for j ournaling the pins 6 upon which the roller 7 turns. 1 The roller is j ournaled near the top of the brackets and is adapted to revolve on its bearing pins 6 in the bearings, and a shade or awning of usual or suitable material indicated bythe numeral 8 is adapted to be wrapped or rolled about the roller. It will be understood that the roller suspended and free to revolve n its hearings and a cord or cable9 which 1s wound around the drum 10 on the roller in the opposite direction to thewindingof isemployed'to opthe curtain or awning, crate the roller and through it the awning. The cable is brought through a suitable opening in the wall of the building. passed over a sheave l1 and may be attached to a cleat 12 as shown, so that the awning may be operated from the interior of the buildmg without opening the window as willnbe understood.

At the lower free end of the awning or curtain a weighted bar 13 is attached which performs the functions of holding the awn-. mg taut at all tunes and also acts as a guide and retainer when the awnlng is being,

lowered or raised.

I11F1g. 3 1s shown the right bracket 1 and inasmuch as the left. bracket is similar in a traveling retainer rod 17 which has a.

movement limited. to the lengthof :the slot 13. This rod has at each end a' forked looking member 18, outside the bracket and provided with end recesses 19, 19 for apurpose to be described.

In connection with the bifurcated or forked section of the bracket I employxan oscillatable or swingingsection 20 which is pivoted at 21 by a pin to the bracket 1, and: by mcans of a second pin 22 movable inthe guide slot 23 in the fork 14 the radius of the swinging or oscillation of the sectionlis limited. This section is also provided with a slot as 241 forming a. continuation of the slot 13' and at its lower end the section 20 is enlarged to provide a space for the heart shaped plate 25. which is fined by a bridge plate 26 to the scctionQOin proper position, because of its size and shape, to form a loop in the slot which at its end is closed by means of the spring detent 27. The loop 28 at its extreme end is bounded by a wall 29 which forms a cam face or edge and the plate 25 is fashioned with a bearing edge 30 extending each side of the ridge or apeX 31 of the cam face 29, and this edge is the contact point when the lu'acket section is being raised as will be described. Below this bearing or contact edge and at the side of the apex 31 opposite the cam 29 a second cam face 32 is provided, and then the loop returns to the slot 24- by way of the gate or detent 27.

At 33 a notch is provided for the reception of the retainer rod 1'? and this notch or recess is located near the lower end of the slots 13 in the wall of the forked brackets 1 and 2.

it will be understood of course that practically all the parts of the brackets and operative parts are of metal, and the parts of suitable size, shape and dimensions.

In operation, when it is desired to lower the awning from the position of Figs. 2, 8, a, for instance, the cord 9, is loosened from the cleat 12 in Fig. 1 and is permitted to slip through the hand as the weighted bar 13, by gravitation, falls and causes the awning to unroll from the revolving roller 7 As the roller revolves it winds the cord on the drum 10. The weighted bar 18 descends through the slots 13 and the retainer rod 17 with the automatic locking devices 18 also travels with the bar, but when the bar reaches the lower end of the slot 13 the notches or recesses 19 of the locking members 18 engage the two pins 21 and 22 and the movement of the retainer rod is stopped. The weighted bar however continues its descent into and through the slots 24, passing over the detents 27 and into the loops 28 of the oscillatable brackets. The weighted bar gradually passes around the first turn of the loop and is halted at the cam edge 29. The cord 9 is now drawn upon, the roller is started to revolve, but the weighted bar is lifted in direct contact with the lifting edge 30' of the plate 25 and as the pull on the cord continues and the rolling or winding of the roller is impeded, the result, is that the oscillatable bracket is swung on its pivot pins 21 to the dottedposition in Fig. 3 and guided by the pins 22 in the slots 23. The cord is now tied to the cleat 12 and the load of the brackets and extended awning is taken at the edges 30 of the plate 25. It will be remembered that the recesses 19 of the locking members 18 are engaging the pins 21 and 22, but during the swing of the brackets the retainer rod 17 has been brought to the position in Fig. 5 where it is seated in the: notches 33, and this rod has also retained the upper half of the awning in a vertical plane as in Fig. 7, while the lower half has swung out with the oscillating brackets with the rod 17 as a pivot point. In this manner the desired angle and shape to the lowered awning is secured. It will be understood of course that this angle and shape may be varied by changes in dimensions and locations of parts and such changes are con templated.

W hen it is desired to raise the awning, the cord is loosened and the brackets with the weighted bar swing back to the full position of Fig. 3. The brackets may swing back by gravity, and the cord is held taut so that when the brackets arrive at the position in Fig. 3 the weighted bar falls from the edge 30 down upon the cam edge 32. A continued hauling of the cord now revolves the roller 7 and the awning is wound upon the roller, the weighted bar travels up the return side of the loop 28, forces its way past the spring detent 27, into the slot 24, through this slot into the slot 13 where it picks up the retainer rod 17 and with said rod is lifted to the top of the slot 13' the rod being carried into theenlarged opening 16. The cord is now secured to the cleat 12 and the awning is thus held in raised position.

Having thus fully described my invention what I claim is z- 1. The combination with a pair of stationary brackets, and a rolling awning supported and guided therein, of movable bracket sections connected thereto and adapted to extend, support and retain a portion of the awning when lowered, and means for releasing the awning preparatory to being raised.
