UNITED STATES CIRCLE-HEAD-WINDOW SHADE.

Application filed March 18, 1926. Serial No. 95,520.

This invention relates to improvements in circle head window shades, and more particularly to shades for windows having a semi-circular section at their top, and which ordinarily is treated separately in equipping such windows with shades.

The object of the invention is to provide a shade which will be of a simple construction, readily installed, and ornamental in appearance.

A further object of the invention is to provide a shade in which plaited material is used, the plaits radiating from the central point of the base, giving what may be termed a sunburst effect, adapted to harmonize with plaited draw shades in the rectangular portion of the window below.

Shades constructed in accordance with the present invention may be either permanent or adjustable, both'types being herein disclosed.

In the accompanying drawings,

Figure 1 is a view in rear elevation of a shade of the character hereinbefore described.

Figure 2 is an enlarged perspective view showing the details of the shade construction.

Figure 3 is an enlarged end view showing the method of attaching the plaited material to the supporting frame.

Figure 4 is a similar view showing another method of applying the shade material to the frame.

'Figure 5 is a view in rear elevation of a shade having adjustable sections.

Figure 6 is an enlarged perspective view showing the details of construction ofthe shade illustrated in Figure 5.

Figure 7 is an enlarged detail view in vertical section as taken on line 77 .of Figure 6, showing one curtain section lowered and the other raised; and

. Figure 8 is a detail view in vertical section taken on line 88 of Figure .7. p A shade of the form shownin Figures 1 to 4, consists generally of a body 1 of suitable shade fabric, fixed to a frame, 2, of semi-circular shape, the whole forming a unitary self-sustaining structure adapted to be mounted in the semi-circular portion or head A of awindow frame. Theframe 2 isof skeleton form, made up of a straight horizontal bar 3, preferably of a light gauge angle iron, which forms the base of the shade, and a round rod-4t bent in semi-circiv lar form and of a radius slightly less than the radius of the completeshade. The ends of the rod are secured to the bar 3 by passing the threaded ends thereof through holes drilled in the horizontal web of the bar near its ends and securing the same by means of nuts 5 applied to the threaded ends of the rod above and below the web.

Thefabric body portion 1 of the shade is fashioned from a sheet of shade cloth, preferably of a relatively stiff grade, which has been subjected to a plaiting process. These plaits for an average sized shade would be about 1 inches in width, and would extend transversely of the sheet, it being assumed that the plaiting would re-f quire a sheet of considerably greater length than width, this latter dimension being equal to the radius of the finished shade.

The shade material in its plaited form is first gathered along one edge with the plaits pressed together, whereupon holes 1 are punched through the plaits near the gathered end. Midway between the ends of the bar 3, is mounted a central anchor rod 6 of semi-circular shape, of a radius of an inch or so. The ends of this rod are also threaded and adapted to be inserted through holes drilled in the horizontal web of the bar 3 and secured by nuts 7,7 in somewhat the same manner as the outer semi-circular rod 4:. The center of the shade material being' anchored in place, the remainder is spread fan-like throughout a semi-circle with the end edges or plaits lying fiatwise along the semi-circular rod 4, the material being disposed toward the front so that the rod is concealed, it being assumed that the vertical web of the bar 3 faced toward the front; As a preferable means of securing the end edges of the fabl'ic body flatwise along the bar 3, thin strips of metal 8 are laid along the endmostplaits and either sideof the central anchor rod 6, and fastened to the bar 3 by short bolts or screws passing through the ends of the strips, the plaits and the horizontal web of said bar. 7 Y

' It is to be noted that in assembling the fabric on the frame, that the vertical web is considered the front of the shade, so that the fastening strips 8 are applied from the rear and thus are concealed or covered by thefplaits. 'In this way, the metal framework of the shade is 'quite concealed, thus giving a finished appearance To further enhance the appearance, a suitable rosette or r 1,609,877 PATENT OFFICE.

medallion 10 may be placed at the center and at the front side of the bar 3, where the plaits converge to a point, thus concealing the mounting at that point as well as adding to the sunburst effect.

As a preferred means of attaching the fabric body to the outer rod 4, a strand of thin Wire 9 isthreaded th ro ughthe edges of the plaits at several points of contact with the rod and thence wrappedaround the rod, this process being carried from plait to plait throughout the length of the rod, as clearly shown in Figure "3; I

As disclosed in Figure 4, another method may also be used, namely, that of punching a. line of 11016 as at 1 through the plaits at the outeredge of thematerial, andthreading the .plaits o'ntothe rod, the friction of the inaterial on the, rod serving to hold the material in place; after it has been spread.

Theshade having thus been. assembled. it is mounted in place by securing the ends of the bar 3 to the vertical side frame members of the window sash A, by suitable supporting fixtures, preferablyallowing for the removal of the. shade so that the window can be cleaned. Thus supported, the body of the shade stands upright closing the semicircular head of the window. without attachment to the .windowframe except perhaps by-a single book a depending .fromrtheto'p of the window frame and engaging the rod t to prevent undue strain. The angle bar 3 may also serve as the transverse top support forextensible draw shades for the window section below, theseshades being suspended fromthebar by cordsor wires, anclraised or lowered by. other. cords andpulleys .se cured to the bar and conveniently concealed behind the vertical front Web therof.

As already suggested, a shade of this character may be made so that it man be adjusted, that is o say. lowered and raised to regulate the amount of light admitted through the top semi-circular section of the window, Figures 5 to 8 disclose a preferred construction where such a modification. is desired. The essential feature of departure in this construction is the parting ofthe plaited shade material into two sections or halves 11., 11 which in the closed position come together, in the vertical line, radiant from the center of the shade. Along the parting edges of each adjustable section are flat bars 12 inserted through; tubular hems 1.1 formed along: these edgesflthe lowerends of these bars having holes .12 whereby these ride on1the;centratlfU-shaped pivot rod 13, which in this constructionis of a slightly greater radius, and flattened at its top, as shown;in Figurefl These bars 12 serve two purposes,.first, tostiflenwthe edges ,of the plaited sections, and s ec ondyv give the necessary Weight, so that the two sections will fall apart and drop down by gravity into open position, with the plaits folded together on opposite sides of the cenl .I f1. ,1,

To a 0rd the shade more stability in its operation; the lower ends of the bars 12, 12 are preferably hinged to a block 14, mount edo'ii the topface of the bar 3. between the ends of the anchor rod 18 suitable hinges 1.5 being for thisf'pui-pase; Theblocl; 15 is anchored ,to the rodby rivets'la and thelhinges similarly "fixedftothe block by rivets Asrl'eai'ly she ii iii Fists-e17, the plaited shade nia t'erialfis punched at both ends to provide holes through, the rods 12-} and h wliich are threaded the liolesjn size so that plaitedinateiial will run freeover the rods in the opening and closingof thefsections."
