This invention relates to sun'shades, and especially that type employed in conjunction with the windows of an automobile, orthe like. The objects of the. present invention is to generally. improve and simplify the constructionland operation of shades of the character described; t-o'provi'de a shade and a sup I port therefor whichis adjustable towindows ofzvarying width; to provide a shade and a support which is adapted to be attached to the inner side of a windowandparallel therewith, so that the window may be opened or closed without interference/with the shade;

to providea shade which may be swung out: wardly from'the window to; assume anyangur 'lar position desired, and which also permits substantial closing of the window :when the shade is so extended; to provide vmeansfor frictionally securing the shade. when in angular extended position, and further to provide means forrpositively 'maintaining the shade against accidentalrelease when extend-,

ed, and for. maintaining a constant tension .on the shade to prevent flapping and noise when drivingi .The shade is. shown by. of'illustration in the accompanying drawings, inwhich: l I I Fig. 1 is a perspective view" of a portion ofan enclosed typeof automobile,such as'a 1 sedan or the like, showing the attachment of the sun shade.

one or more. side doorsfwhi'ch. are opened for entranc e or'ex'it from the car. Doors of such cars are usually provided'with sliding windows, which may be opened-or closed for ventilation and circulation of air.

Fig. H is; a perspective View of one of the. friction-spring arms." v Automobiles of the'enclosed type, such as sedans, coupes, etc., are usually provided with vol Windows of this character usually consist" i of a section of plateiglass,such as shown'at A', which are supported in a frame which;

may be raised and loweredflby mechanism,

not herej i-llustrated- .The plateglass window is mounted in guideways,rsuchas shown at B, formed in opposite sides of the door, and these guideways, are lined with 'felt strips or the like, :to prevent rattle. ;The

problem'of mounting a sun shade in the window opening of an automobile door islnotfa simple one, as the shade, together with its support andjoperating mechanism must be neatand compact,-it 1nust assume as little space as possible. and it must not interfere: with theopening and closing of the window.

The sun shadeforming the subject matter of the present application is simple and neat in appearance, it may be rigidly secured to the inner surface of the door,,andit does not interfere with'the opening and closing of the window. r The sun shade, here illustrated, consists of a shade clothC, and a spring actuated roller D, upon which it may be Wound in the manner of an ordinary shade cloth, when not inuse. Any desired form of shade cloth may be employed. It is attached to the sur- 7 face of the shade roller D, in the usual manner, and the shade roller is provided with a the usual internal spring mechanism, which is Wound when the shade cloth is extended, so as to be placed under suiiicient tension to rewind the shade cloth when it is not required. This mechanism is all common and illustration thereof is thought unnecessary."

The shade roller is, in this instance, supported in a pair of brackets,s,uch as shown in Figs. and 13. These brackets are sub 2 stantially identical in construction. They consist of side and top plates, such as indi cated at 2 and 3, bent at right angles to each tor-media the upper plates 3 bfthe respective brackets- The end plates 2 ofthe brackets are slightly spaced with relation to the sides of the window opening, and the purpose of this spacing will later be described;

Qne of the brackets, such as shown. in Fig. 5 is provided with a slotlike opening 8, for the reception or the flattened pins of the shade roller, while the opposite-bracket is merely provided with a rounded hole for the reception ofthe shaderoller pin. The free end of the shade cloth is, in this instance rovided. with a-sha'de stick generally indicated at Eg which is grasped whenit is desired to extend or retract the same. The

shade stick employed in this instance consists of a rod see Fig. 9, which is adapted to receivea socket member 11 at each end.

The socket member as 'shown'in Fig. 10, is

provided with a socket orire'c'ess to receive the end o-f the rod 10-, and is provided with V a head 12, and a reduced portion 13, which is adapted to be received by a slot or guide way 14, formed in the extension bracket 15-- see Fig. 11. There are two of these brackets,

one at each end of the shade roller, and they are pivotally attached to the brackets shown I in Figs. 5 and13, as will now :be described.

'Formed in the side "section 2 of each bracket, is a journal opening 16, and journal'ed therein is a short-section of hexagon rod, such as shown at 17, se'eFigs. 3 and 8. r

S'ecur'ed tio'th'e inner end of the hexagon rod or pin 17 by riveting or the like, is a friction -:spring ar1n 18, see Figs. 3, 5 and 14. Se-

cured to the opposite end of the hexagonal rod or pin is a sleeve or socket member 19,

and this is adapted to receive a cross rod 320,

surface to slip over the rod 17, and it is riveted or otherwise secured thereto, as indicated at 21. The upper ends of the extension brackets 15 are slightly oifset, as shown at 22, see Figs. 3 and 11, andthe offset ends are provided with hexagonal perforations 23, to permit them tobe slipped over the pins or rod section l7.- A friction washer 24, see Figs. 3 and12, is interposed between the side late 2 of the bracket, and the extension racket l 5,'andthis washer cooperates with the spring arm 18, to frictionally secure the extension bracket arm 15, in'any angular extended position desired, see, for instance, the dotted line positions shown at 25 and 26in Fig. 2.

From the foregoing lescriptioii itshould be noted that the shade stick 10, and the rod 20, are both supported in socket members in dicated at 11 and 1-9 respectively. This is important as it permits-the shade to be installed in windows of varying'widththat is, the rods 10 and20n1'ay be cut to desired length to suittheparticularw-indow in which'it is to 'beiinstalled, and they are then merely insert'ed in the socket members 11 and 19. In actualbperation; hexagon pins are inserted in the respective brackets shown in Figs. 5 and 1 3.- Thespring arms 18 are-attached and e The friction washers 24 are then applied on the opposite; side, and so are the extension bracket arms 15. The sleeves or socket members 19 ar'e'next applied and riveted, or otherwise secured and the assembly is then completed. This, of course, is all done at the factory'andithe brackets, when so com- -pleted, are. sold to the'di'stributo-rs or retailerstogether'with the shade roller D. -These are provided in different lengths. Long rods,

such as shown at lO and 20, may at the same time be supplied and these are then merely cut to the desired length when installation is mad; i i 5 Everything required, is accordingly standard with the exception of the shade roller, and this may be provided in different lengths.

to suit windows of 'difierent widths.

' In actual operation, when installing the sun shade, the rods 10. and-20 are-'cut-the' proper length and placed in the socket memhers 11 and 19 respectively. The shade roller is placed'between thebr'ackets and the brackets are secured on the insideofthe window opening by inserting the screws6. This'completes theinstallation'andthe shade is ready for use. v

It will be noted that the entire installation is made interior of :the' plate glass window, indicated at A,Isee Figs. 2 and 4-.

These slots iarelhook-shaped at their. lower ends, as shown. at 14 in other words, the shade is lowered until the headed members 12, and the reduced ends 13 of the socket'members engage the hooks 14*. "They will here' secure the shade against accidental release,

and the spring in the shade roller will maintain the shade cloth under sufficient tension to prevent flapping and noise when driving.

Onthe other hand,'if it is desired to extend the shade to assume an an- L 4, dow opening,it is, possible to substantially close the window'A. That is, it may be. raised up into contact with the extension bracketarm or substantially so,'this being a great advantage, as itis often desired to exclude both wind and rain when driving undercertain conditions, and still retain the benefit of having the shadeexteriorof the window.

stated that a slight spacing was provided between the sidesof the brackets shown in Figs. 5' and 13, and the sides of the window 7 opening. This spacing is clearly shown at 35,

see Fig. 3. This spacing is necessary, as free movement of the spring arms 18 is thereby permitted. These springs, together with the washers 24, take up wear, and at all times exert sufficient friction'to vprevent rattle and to secure the extension bracket arms 15 whenever extended. The 'olfset 22, at the upper .ends of the extension bracket arms, as shown in Fig. 11, is approximate tothe thickness of the washers '24. The extension bracket arms thus lie substantially flush with the inner surface of the side ,plates 2 of the brackets,

and a neat, compact structural arrangement is provided.
