JOHN CARLIN, OF CHICAGO, ILLINOIS.

AWNING.

Specification of Letters Patent.

Patented May 23, 1916.

Application filed October 8, 1914. Serial No. 865,620.

To all whom it may concern Be it known that LJOHN CARLIN, a citizen of the United States, residing at Chi: cago, in the county of Cook and State of Illinois,.haveinvented a certain new and useful Improvement in Awnings, of'which the following is a specification. I

My invention relates to awnings and-the general object of the invention .is to provide an awning which may be easily manipue lated' also one which will, when furled or raised, occupy but small space and cause the component parts to assume a position I invention which contribute to the accomferred form of cord guide.

plishment of the general object are; first, to provide an extension member located in position to be engaged and disengaged by the front rod of the awning when the latter is lowered and raised: second, tofiprovide simple and ellicient means for attaching the extension member to thewindow. frame and at the same time tending to holdsaid extension member invertical position where it will be up out of the way when not in active use: third, to provide certain details of construction which will be hereinafter more particularly described and claimed.

I accomplish my objects "by the construction illustrated in the accompanying draw.- ings, in which i,

Figure 1 is I a front view of a window equipped with my awning, the awning being shown to be in raised position. Flg. 2

is a side view of the parts shown in Fig. 1.

Fig. 3 is similar to Fig. 2, but shows the awning lowered. Fig. 4 is a detail viewed from the front of the window showing the manner of attaching the extension element to the window casing. Fig. 5-is a vertical sectional view transverse to the cross bar of the extension member showing a pre- Similar numerals refer to similar parts throughout the several views. I

In the forms selected to illustrate the invention, the awning, 1 is in-the form of astrip 'ofcanvas or other suitable fabric, carried by a spring roller 2 mounted inbrackets 3se'cured to the casing 4. .By preference the ordinary Hartshorn or spring shade roller is used. In order to stifienthe lower edge of the awning a front rod 5 is preferably secured thereto in the ordinary manner. The awning is manipulated by a pull cord 6 which is fastened to the lower end of the awning and preferably is connected directly to the front rod itself.

A horizontal roller 7 is journaled in bracketsS fastenedto the front ofthe win-.

dow casing, and by preferencethis is 10- ca'ted substantially on a level'with the cross barswhich form the lower bar of the upper sash and the upper bar ofthe lower sash. Below roller-7 is an extension element comprising the cross bar 9 and the side bars 10, 10.v

The partsare so arranged that cross bar 9 will come about an inchbelow the bottom of the roller/7, approximately at the elevation of the sash bars just mentioned. The side bars 10 are arranged in front of the upright side members of the window casing 4. As a result of this arrangemenain which the side bars.l0 are hidden from the view of a person within the Window by the side members of the frame, and the roller 10 andcross bar9 are hidden-from the person by the above mentioned cross bars of the upperand lower sash, and the shade roller 2 is located at or near-the top of the window frame, the parts of the awning, when out of use, are practically invisible frominside the window and hence do not in any way obstruct the view. For this-reason by simply removing the awning and its shade roller, the remaining parts may be left in position during thewinter without causing any annoyance to the persons within the room; henceflwithan awning of my construction it becomes -unnecessar'y-.-to attach and detach the fixtures every spring and fall, as is common with most devices of this class.

At the lower end the extension bars 10 are secured by'cotter pins 12for otherwise to helical springs 13, the lower endof the bar passing down into the springs part way to obtain rigid connections. The lower end of each spring-is connected by a screw 14 or other means to the front of the window casing. In consequence the springs ,12 tendto normally hold the extension'bars l0 upright,

but permit said bars to be swung down when I in position upon the pulley and also acts as a stop against which the front rod 5 of the awning engages when the awning is be ing lowered. At the window sill 18 cord 6 passes under a pulley 19, which is preferably a catch pulley so that the cord may be retained in any desired position.

In operation, assuming the parts to be in the normal non-acting condition shown in Figs. 1 and 2, the operator lowers the awn ing by simply drawing in' upon the pull cord 6. For the first half of its movement, that is, until the front rod-5 reaches the roller 7, it will passstraight down, close to'the front of the window casing. If the operator continues to draw in on the cord the'front rod '5 of the fabric strip will pass behind the roller 7 and almost immediately thereafter will seat upon the stop 17 on the cross bar 9 and from that point on will draw said cross bar and the side bars 10 downwith it; until the parts have reached the limit of their movement, as suggested in Fig. 3'. If the operator now releases the cord the parts will move in the reverse direction, the springs 13 causing the bars 9 and 10 to rise in unison with the front rod 5 until'they have resumed their upright position adjacent tothe front of the window casing. Thereafter, the awning will rise in the-manner of an ordinary shade, the roller. 7 holding he cord-6 close to the window frame and thus assisting in retaining the front rod 5 of the fabric strip close to the front of saidframe. F urthermore, by fastening the lower end of the pull cord at the catch pulley 19, said'cord cooperating with the roller 7 will keep the rod 9 and side bars 10, 10 close to the window frame. r i

From the foregoing it will be evident that with my awning the difficulties of manipulation are reduced to a minimum, it being necessary merely to draw the cord 6 in or out, the springs in the roller 2 and at the bottom of the side bars 10, relieving the op erator of the need of personally raising any weight. Another advantage in my construction is thatthe extension member, consisting of the bars 9 and 10, simply swings up and down but never leaves its place in the sense of traveling upward with the awning. In

other words, the extension member does not travel vertically but simply swings from verticalto horizontal position and vice versa. Consequently there is no weight to be raised and lowered by the operator, nor does the spring of the roller 2 have to raise the weight of the extension member. Said extension member is capable of raising its own weight in rising to standing position and in fact as commonly constructed asslsts the spring roller 2 in raising the awning so long as the awning remains in engagement with said extension member. Another. advantage of-my construction lies in the fact that there are no loose parts. I have dispensed with all vertical guide rods and with sliding members, and the result is. that there is nothing to rattle in the wind eitherwhen the awning is lowered or when it is raised or when it is in intermediate position.

As a result of my. preferred method. of connecting the side bars 10 to the springs 13, the tension of said springs may be readily adjusted. If a greater stiffness or tension is desired, all that is necessary is to withdraw the cotter pin 12 and lower the rod to a point farther down in the spring. In the lower position a shorter portion of the spring is left for flexure and in consequence (within reasonable limits) the tension of said spring may be increased or decreased to any desired extent.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is;- 4

1. In an awning, the combination of a shade roller, a fabric strip mounted thereon, a cross roller in an intermediate position upon the window frame, a cross bar beneath said cross roller in position to be engaged by said strip when said strip is being lowered,

sidebars. supporting said cross bar, means attached. to said side bars and attached to the window frame for normally holding said side bars upright, and means passing in engagement with said cross roller when the awning. is raised for bringing said strip into engagement with said cross bar as thestrip descends.

2. In an awning, the combination of a shade roller supported at the top of the window frame, a fabric strip wound thereon, acord for raising and lowering said strip, a cross bar, .an eye on said cross bar through which said cord passes, side bars supporting said cross bar, and means connecting said side bars with the window frame, said connecting means permitting said side bars to rotate in a vertical plane and preventing said side bars from moving bodily in a vertical direction.

3. Inan awning, the combination of a spring roller near the top of the window frame, a fabric strip mounted on said roller, a pull cord-for operating said strip, a center rollerbehind-which said cord passes, a cross bar near said roller, a guide for said cord located on said cross bar, said guide also serving as a stop to engage the lower edge of the strip, and connecting means, for articulately connecting said cross bar to the window frame, said connecting means constraining said cross bar to travel approximately on the arc of a circle only.

4. In an awning, the combination of a spring roller near the top of the Window frame, a fabric strip mounted on said roller, a center roller, a cross bar beneath said center roller, side bars supporting said cross bar, springs fastened at one end to said side bars, and at the other end immovably fastened to @opies of this patent may be obtained for he cents eseh, by dressing the "Commissioner or Patents,

the window frame, an eye on said cross bar, 15

and a pull 'cord fastened to said strip and passing behind said center roller and through said eye to thereby cause the strip to actuate the cross bar when the strip descends, and rotate the cross bar and side bars 20 in opposition to the ressure of the springs.
