Qne edge :oa fleXible-shadeelement8fis secured te the.4 roller so. thatit may be Wrapped; about l the same, Whileitsopposite f endis secured ftoal rigid bar 9. The shade is supportedwhen extended'at a desired anglerelative; to horizontali plane. transversely of the-carby folding arm units extending. between the brackets ears and `the -bar 9 at the ends of the latter. The arm 1units each 80;

and in a. substantially vertical plane so that the said members can fold in a horizontal plane. The opposite end of the block abuts against the inner face of the bracket ear 5. A rigid washer member 14 abuts against the opposite face of the block in alinement with the ear and is recessed into the block as shown in Fig. 7.

The washer extends to the plate 6 and abuts flatly thereagainst so that it cannot turn. The screw l passes through the ear, block, and washer, and is threaded in the ear and washer. By this means not only do the` opposed screws form the bearings for the roller f spindles but also provide means for clamping theblocks 13 firmly in place, while allowing them to be turned up or down somewhat about said screws as an axis. Since the arm members are rigid with the block in a vertical plane such movement of the blocks turns the arms up or down also and of course alters the angular setting of the shade roll to a horizontal plane. The shade extends to the bar from over the roller, as shown in Fig. 4, so that said arms may fold under the shade.

Springs 15 are applied to lthe arm members and act to normally hold the same extended, so that the shade will likewise be held extended. To rotate the roller so that the shade will be wound thereon, and the arm units moved to a folded position against the resistance of the springs, and to also hold said springs constantly under tension so that the shade will always be taut, I provide the following means:

Mounted on the inside of the door in transverse alinement with one end or the other of the roller, as may be most convenient according to the particular design of car, is a verJ tical guide bar 16. Slidably mounted in this bar'for movement lengthwise of the same is a slide block 17 having an outwardly nroj ecting finger piece 18 rigid therewith. ivoted in connection with the block above the finger piece is a. pawl 19 which is adapted to engage a row of ratchet teeth 20 or the like provided in the bottom of the guide. The ratchets and pawl are arranged so as to hold the slide block against upward movement in the guide and the pawl may be released at will from the ratchet teeth by means of a finger pad 21 which is provided with the pawl and which extends outwardly therefrom in overhanging relation to the finger piece 18, as shown in Fig. 6.

Fastened at one end to the pawl above its pivot is a flexible element 22 which is preferably in the form of a thin fiat metal band, so that it has little or no tendency to stretch. This band extends tothe top of the guide over a pulley 23 and turns through a hole 24 cut transversely through the door and the bracket plate 6 on a level with the top of the roller'. Outwardly of the door said element 22 is wrapped about and secured to the adjacent end of the roller beyond the shade. The band passes about the roller from the top so that with a pull on the band the latter becomes unwound from the roller as the latter rotates, while the shade is rolled thereon. lVhen the `slide block is at the top of the guide the shade necessary to prevent such extension of the shade as would cause the members of the arm units to move to a full dead-center position relative to each other, which would of course prevent or seriously interfere with the desired folding movement of the same. In other words said arm members even when the shade is fully extended are disposed so that they assume an angle of less than 180 degrees vwith each other, and so that the 1ncluded angle faces toward the adjacent end of the shade. This of course enables and causes said arm units when folding up to project under the shade instead of folding in the opposite direction or beyond the ends of the shade. Since the springs 15 are constantly tending to straighten the arm units they alsov L.. exert aconstant effect on the shade, the roller,

and the band 22, so that the shade and said band are always` under tension. It 1s .therefore unnecessary to apply a spring directly to the pawl to hold the same engaged with the guide bar ratchets, since the natural and constant pull of the bands on said pawl automatically holds it in engagement with the ratchet. From the foregoing description it will be readily seen that I have produced such a device as will substantially fulfill the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is j j 1. In a sunshade including spaced bracket ears,fa roller extending between the ears and having end spindles, and arm units, a shade element secured along one edge to the roller and arm units extending between the ears and the opposite edge of the roller; blocks on the arm units abutted against` the inner adjacent faces of the ears, washer elements abutting against the opposite faces of the blocks, and combination clamping and pivot screws passing through the contactin T ears, blocks and washers the adjacent inner ends of the screws iro being bored to a certa-in depth to formV bearings for the roller-spindles.

2. In a sunshade including spaced bracket ears, a roller extending between the ears and having end spindles, and arm units, a shade element secured along one edge to the roller and arm units extending between the ears and the opposite edge of the roller; blocks on the arm units abutted against the inner adjacent faces of the ears, and a common means for yieldably and pivotally clamping the blocks against the ears and for supporting the roller-spindles.

In testimony whereof I aiiX my signature. BENJAMIN F. WALKER.
