. March 1.0, 1942- F. G. DUEWEKEI METAL AWNING Filed May 24, -1940 Patented Mar. 10, 1942 UNITED STATES `PATENT OFFICE METAL AVVNING Florian G. .Dueweke, Detroit, Mich.

Application May 24, 1940, Serial No. 336,971 4 claims. (cl. 15o-44') The present invention pertains to new and useful improvements in an awning structure.

The invention embodies utilitarian features in that owing to the entire structure being formed of metal, certain desirable conditions conducive to fire prevention are apparent.

It is an object of my invention to Iprovide an awning structure so :constructed and arranged as to afford adequate protection against natures elements, wind, rain Iand sunshine, while also sewing to beautify dwellings and buildings.

Another object of the invention is in the provision of an awning structure of fire resisting material, that may be raised or lowered with ample ease.

A further object of the invention is to provide an awning structure that may remain axed to a building throughout an entire season, obviating seasonal installations.

Still a further object is to so arrange and construct parts as to provide a simple awning structure having ease of operation and lbeing economical of manufacture.

Other objects will appear hereinafter.

The invention can best loe interpreted by reference to the appended drawing, which forms a -part of this specication, with similar reference numerals referring to similar parts throughout the several views and in which:

Fig. l is a front elevational View of the awning structure secured to a :conventional window, with parts of the frame broken away, the awning being in raised position;

Fig. 3 is an enlarged fragmentary view of the awning and supporting rod with -parts broken away;

Fig. 4 is a plan view taken upon line 4-4 of Fig. 3, with parts broken away;

Fig. 5 is a sectional view taken along line 5-5 f Fig. 3; l

Fig. 6 is an enlarged side elevational view of the supporting arms in their relation, when the awning is in lowered position;

Fig. 7 is a bottom plan View of the structure shown in Fig. 6; and

Fig. 8 is an elevational view taken upon line 8-8 of Fig. 1.

The invention is shown mounted upon a conventional window easement 3, provided with the upper and lower sashes and 'I slidable therein.

'lhe awning structure is attached to the upper u section 9 of the window easement by a semi-circular housing II having right angle flanges I3 thru which .project fastening screws I5 into the window Casement. The housing is formed with end walls Il into which are suitably journalled stub shafts I9 and 2 I at the respective ends of a roll 20 therein. Upon this roll a flexible metal shade 4I is adapted to be rolled, one end thereof being attached to said roll.

The shaft I9 terminates in the side wall of the housing. The shaft 2| has a collar 23 upon the inner side of the side wall, and continues therethrough, having a sprocket wheel 25 xedly mounted thereon, the shaft extending into a suitable journal or bracket 2l, a'ixed to the aforementioned flange I3 on the housing,

The awning structure proper is constructed of a frame having a horizontal lower member 29 and vertical side-members 3| which, at their upper ends, are swing-ably mounted on pins 33 in the end Walls Il of the housing, permitting the frame to be swung into an angularly raised positicn or into a lowered position against the Windowcasement. Each of the side mem'bers is so constructed as to form a track, each side member having a right angular flanged portion 35 along its outer side, and each, upon its inner side, has a parallel member 3l spaced therefrom. Sound insulating material 39, such as felt, may be positioned there-between to accommodate the ilexible metal shade 4I, adapted to slide therein.

The frame as described thus far is maintained in its respective positions, i. e. parallel or angular to the Window easement by means of a pair of arms. Each arm consists of two sections 43 and 45, each section 43 being pivoted in a bracket A inner side of the flange 44 of the ,arm AsectionV Y v43, with the other end received in a ygroove 5l.

in the `arm section 45, normally urging the respective arm sections into parallel axial relation to one another.

Referring to Fig. 1 it will be noted that the y awning, or flexible shade 4I, is shown in a raised position, admitting clear, unobstructed vision thru the window sashes and 'I in the casement.

The metal shade or awning is raised or lowered to its respective positions thru suitable means here shown as comprising a handle 59, mounted conveniently upon the inside of the easement and journalled therein as at 6I, with an extension shaft 63 protruding beyond the outer side of the veasement and having a gear or sprocket wheel 64 keyed thereon for rotation therewith, with a cooperating endless chain 65 having its other end passing around the periphery of the aforementioned gear upon the shaft 2|, and passing over an idler or guide sprocket 66 of smaller diameter `for rotation of the shade roll.

The flexible shade 4| slides in the track-like groove formed by the flanges and 31 and is retained therein by a transverse supporting bar 61, around which one end of the shade 4l is secured.

A pair of chains 69 are so positioned on the inner side of the side members 3l, each having one end thereof attached to the transverse bar 61 of the shade 4I, and the other end secured to the pivot pin 49, journalled in the arms 43 and 45, that upon rotation of the shade-rolls 25J in a direction to raise the shade 4l from the lowered position as partly shown in Fig. 3 to the raised position shown in Fig. 1, first the retention spring will yield and then the pairs of arms will assume a position as indicated by the dotted lines in Fig. 2 and subsequently fold parallel and adjacent one another into a closed position of the awning frame structure as shown in full lines in Fig. 2.

Operation As shown in Fig. l the shade is in its raised position and the frame proper is in parallel adjacent relation with the easement.

Upon rotation of the handle inside the casement by the operator, the sprocket and chain means will rotate the shadelroll, effecting a lowering of the shade in its track, and the pin 5I in arm will descend until it reaches the bottom of the slot 53. At this point the retention springs will endeavor to return to a normal relaxed position, eiecting the l-owered position of the entire awning structure.

Aside from the specific embodiment of the invention herein shown and described, it will' be understood that numerous details of the construction may be altered or omitted without departing from the spirit and scope of the invention as disclosed and claimed, and .that'I do not desire to limit the invention to the exact construction herein set forth.
