WINDOW SHADE AND AWNING.

SPECIFICATION forming part of Letters Patent No. 317,238, dated Why 5, 1885.

Application filed August 27, 1884.

To all whom it may concern.-

Be it known that 1, DAVID It. STEDMAN, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in YVindow-Shade Fixtures, of which the following is a specification.

My invention principally relates to devices or fixtures for utilizing window-shades as awnings, in which the shadeis held extended from the window, and thus made to serve as an awning, by means of arms extended outward from the window-casing and connected to the shade; and the invention consists in features hereinafter described, and specifically claimed at the end of this specification.

In the accompanying drawings, Figure l is a front elevation of a window and shade with my invention applied, and Fig. 2 is a transverse vertical section of the same. Fig. 3 is a View similar to Fig. 2, showing the application of the invention to a shade, the roller of which is mounted at the lower part of the window instead of at the top. Fig. 4 is a front view of the shade and one of the arms for holding it extended from the window, showing the connection of the arm to the window-casing in detail; and Fig. 5 is a detached view showing detail parts hereinafter described.

In the drawings, a is a window-casing; b, the sill of the same, and c c the sashes.

d is a shade secured, as usual, to a roller, 6.

The arms ff, which are used for holding the shade extended from the window to form an awning, are pivoted to the sides of the casing a, preferably just below the lower rails of the two sashes c 0, when both sashes are fully raised, as shown. The arms f are of such a length and are pivoted to the casinga at such a height above the sill b that they may be placed in a vertical position against the sides of the casing without being removed from their pivots, as will be understood from the drawings. (See Fig. 2.) This position of the arms (in which they can be conveniently placed by simply turning them on their pivots) renders them entirely out of the way when not in use for holding the shade projected from the window. Then, also, the arms are in this position, the shade may be lowered to (No model.)

the bottom of the window and held in a vertical position by being secured to the ends of the arms, and thus be prevented from being blown out of place or fluttering when the window is open.

The manner in which the arms are secured and pivoted to the casing a is as follows: Metallic plates 71, having stems 9 cast with them or otherwise rigidly united with them, are secured to the sides of the casing. The stems g are screw-threaded and each formed with a longitudinal groove, 9. (See Fig. 5.) Ahole is formed in the upper ends of the arms f, through which the stems g extend. \Vashers 75, having inwardly-projecting tongues or lugs 7r, fitting in the grooves g in the stems g, are

passed over the stems and clamped against the arms f by means of thumb-nuts 2'. therefore be seen that although the washers k may be clamped tightly against the arms f by the nuts 2' the turning of the arms upon the stems g, for projecting the shade from the window or changing the arms from one position to another, will not cause the nutsito rotate,and consequently tighten or loosen,the arms by friction, since the washer is, intervening between the arm and nut, will be locked against rotation by means of the lug k and groove 9''. The arms may therefore be clamped tightly to the casing a, so as to be held in the desired position and be turned from one po sition to another at will without disturbing their connection with the casing, and consequently they will be held with equal firmness in their new position.

The sides of the upper ends of the arms f adjacent to the plates h are preferably cut away, so that the remaining portion of said sides will be flush with the casing c,as will be understood from Fig. 4. This enables the arms to bear against the casing as well as against the plates, and a broader bearing-surface and more rigid connection of the arms with the casing are thereby secured.

hen the shade is hung from the roller atthe top of the window, as shown in Fig. 2, the arms f f may preferably be connected to the lower part of the shade by means of rings 0, secured to the stiffening-rod s, and adapted to he slipped over hooks p on the arms, as best It will shown in Fig. 4. By this means the shade may be very simply and quickly attached to and detached from the arms.

It will be seen from the dotted lines in Fig.

2 that by adjusting the arms finward from the window at an angle to the casing 11, with the shade attached to them, the latter may serve to deflect the light coming in at the window to the lower part of the room, as is sometimes desirable. In this case, in order that the lower portion of the shade alone may be at an angle, as is preferable and asis shown, Iprovide wire projections t,adapted to be projected horizontally in a direction across the window at the side of the shade which faces the interior of the building, to hold the upper portion of the shade in a perpendicular position, as shown. These projections may be formed of wire doubled, and having its free ends bent at right angles and adapted to fit in bearings formed in the sides of the notches Z in the plates h, as will be understood from Fig. 5. The projec tions t may thus be turned up perpendicularly against the sides of the casing 0 when not in use, and thus be out of the way.

In Fig. 3 the roller 6 is represented as secured to the bottom of the Window and arranged to be raised (instead of lowered) by means of a cord passing over a pulley at the top of the window, as is well understood. In

applying my improvements to the shade as thus arranged I mount the ends of the roller upon the armsf, as shown. The ends of the armsf to which the rolleris attached should be united by means of a rod, 1", rigidly secured at its ends to each of the arms f, to prevent them from separating accidentally or otherwise far enough to render the roller liable to be unintentionally detached from its bearings.

lVhat I claim as my invention is- 1-. The combination, with the shade d and arms f, of the stems g, to which the arms are pivoted, the washers 70 upon said stems at the sides of the arms and locked against rotation, and the clampingnuts z, substantially as set forth.

. 2. The combination, with the shade d and arms f, of the plates 71, having grooved screwthreaded stems g, to which the arms are pivoted, the washers 7c, having lugs 70, fitting in the grooves in said stems, and the clampingnuts 1', turning upon said stems, substantially as set forth. 7

3. The combination, with'the shade d and arms f, of projections, as t, secured to the casing a at the inner side of the shade, substantially as and for the purpose set forth.

Signed by me this 25th day of August, 1884.

DAVID R. STEDMAN.
