PATENT OFFICE NELS NELSON, 0F DES MOINES, IOWA WINDOW-AWNING CONSTRUCTION Application filed June 8, 1925. Serial No. 35,775. i i

The object of my invention ,is to provide a window awning construction of simpleand aratively easy to manufacture. i More particularly,my invention relates to a track or guidein which a U-frame to which the awning canvas is fixed may travel a predetermined distance and thereafter the u-frame will swing outwardly and downwardly as though pivoted to'the track.

Still a further object is to provide a casing for the awning when it is in rolled-up position 7 and to provide a connection between the canvas proper and the U-frame, so that the connection will serve as a closuremember for completely enclosing the casing in which the canvas isreceived and thereby preventing any portion of the canvas being exposed to outside atmospheric conditions.

Still a further object is to provide a substantially grooved track in which is slidably mounted ball members formed on the free ends of the U-frame, which ball members hecome temporarily anchored in the lower ends of the track, whereby the frame may be swung outwardly and downwardly and retained in its downward position.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various partsof my construction, whereby the objects contemplated are attained, as hereinafter more fully set forth pointed out in my the accompanying drawings, in which:

V Figure 1 is a front plan View of a window with my window 1y withdrawn. o 7 Figure 2 is a side view of the awning showing it in partly withdrawn position. I

Figure 8 is anenlarged, sectional view of the track in which the U-frame of the awning travels, one position being'shown in dotted lines.

Figure 4 is a sectional view through the awning shown thereon partcasing in which the awning is mounted showing the connection between one endof the canvas and the cross memberof the U frame; and V a 1 Figure 5 is a detailed, sectional view taken by screws or the like.

substantially at the joint between two portions of the track shown in Figure 3 of the drawings.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally a window frame or casing, which is provided with the ordinary window sashes 11. y

Secured to the upper cross member of the frame 10 is a casing 12 having an opening formed in its bottom near the forward wall. The edge of the material of the casing12 at the opening referred to by the reference numeral 13 is bent back and doubled over, so as to provide a smooth edge over which the can vas of the awning, which will hereinafter be described, may travel. p i V Mounted within the casing 12 in anysuitable manner is a spring-actuated roller 14. I have not shown the spring of the roller 14 and any suitable type of spring actuated V roller may be employed.

'Mounted upon the roller 14: is a strip of canvas 15, which is adapted to be rolled. around the roller,as clearly shown in Figure 4 of the drawings. 1

Oneach side of the frame 10 is a track 16, which is formed of a pair of similar sections of sheet metal, which are formed so as to be substantially circular in cross section, and to have a pair of out-turned flanges 17. The flanges 17 tend to reinforce and strengthen the track 16. 5

The two parts of the track 16 are connected togetherbyany suitable fitting 18, which is screwed or otherwise fastened to the frame 10. I p v V The upper end of thetrack 16 is secured to the casing 10 by a screw 19 passing through an opening in the track and entering the frame 10.

The lower end of the track 16 below the fitting 18 is inclined slightly outwardly.

A fitting '20 having a substantially u-sha'ped opening 21 therein coacts with the lower end of the track 16 and forms a continuous passageway. r

Thefitting 20 is secured to the frame 10 i It is formed with a yoke-shaped socketportion 29 which engages thelower end of the track 16.

Slidably mounted relative to the track 16 is a U-shaped frame 22, which has a pair of ball members 23 fitted in its free ends.

The ball members are designed to travel in the tracks 16. The space between the two the ball members 23 therein and prevent accidental displacement sucl as might occur, dueto the action or" the wind. For this purpose, the ball members 23 are of elongated form, being substantially semi-spherical at their terminal portions and of greater diameter thanthe end portions of the U-shaped frame 22 to which they are attached. The innerendportions of the ball members 23 are substantially frusto-coni'cal and taper gradually toward the frame arms. The depth of the socket openings in the fittings 2O corresponds substantially with the length of the ball members 23. V

W'h en draft is applied to the U-shaped "frame 22 by means oi the member 27, the ball members 23 travel downwardly in the channeled guides 16 and when they reach the lower ends of said guides, they move rear wardly. and upwardly into the socket openings of the fittings 20 and are efiectively retained therein so long as tension is maintained on, the draft member 27 for holding the awning in any of its adjusted positions. When draft onthe member 27 is released, the action of the spring roller 14 serves to pull upwardly on the awning 15 and on the outer end of the U-shapedframe 22. Such pull causes the ball members 23 to slip past the lower ends of the sockets inthe fittings 20, the tapered portions of the ball members sliding around'the point which separates the sockets from the guide tracks. Thereafter, the ball members travel upwardly in the channeled members to the position shown by solid lines in Figure 3.

The awning or canvas 15 is secured to the cross member 24 of the U-frame the use of a metal clip 25, which is bentto substantially U-shape and extends around the cross member 24 and has its ends turned inwardly towards each other to receive therebetween the free edge of the canvas 15.

The connecting member24 ofthe U-frame 22 is permitted to move relative to the clip 25 The canvas 15 is connected to the clip 25 by suitable rivets or the like 26, which ex tend through two sides of the clip 25 and also through the canvas which is received therebetween.

The clip 25 is designed to extendup into the casing 12 and fill the opening 13 thus sealing the entire casing 12 and protecting the canvas 15.

The metal clip 25 around the U-frame 22 gives me a connection which permits tree and easy movement of the U-itrame, and at the same time serves as a closing member .t'or the opening in the casing 12.

Any suitable control may be used for movement of the awning from one position to another, and I have shown in the drawings a chain 27, which extends around a suitable pulley or the like 28 mounted on the sill of the frame 10.

The roller 14, which is spring-actuated, tends to hold the awning in its closed or rolled up position, and when in this position, the parts are as shown in Figure 3 of the drawings.

When the chain 27 is pulled downwardly, the first thing that happens is to cause the awning or canvas 15 together with the U- frame to be pulled directly downwardly until the lower ends ofthe U-frame or balls 23 are engaged with the passageway 21 in the fitting 20.

The position of the parts just described is clearly illustrated in Figure 2 of the drawings.

Further pulling on the chain 27 will cause the U-frame to swing outwardly and thereafter to swing, downwardly, so that the awning may really be substantially flat against the window when completely drawn down.

In most cases, however, the awning is used as an ordinary awning, that is with the canvas portion inclined outwardly, as shown in Figure ,2 of the drawings.

The awning when serving as a curtain or the like is completely drawn down, and the U frame assumes the position shown in dotted lines in Figure 2.

The ball members 23, traveling in the passageway21 and the fitting 20, pass around a shoulder formed in the fitting 20, which gives to the U-frame the desired movement, that is engagement of the balls 23 around the shoulder in the fitting 20 causesthe inner ends of the U-shaped member to remain positive.

When the inner ends of the Ushaped member 22 are'in engagement with the fitting 20, then the parts, move as though the inner end of the U-member were directly pivoted thereto.

The metal clip 25 extending around the connecting member 24 of the, U-trame tends to strengthen the U-frame and prevent any possible bending or sagging at the cross member 24. The metal clip 25 also serves to prevent the awning or canvas, which otherwise would extend around the connecting member 24 from wearing out.

Some -changes'may be made in the arrangement .and construction of the various parts .ofmy device, without departing from'the real spirit and purpose of my invention, and it is my intention to cover bymy claims, any modified forms of structure or use of mechanical equivalents, which may be included within their scope.
