WINDOW-SHADE-HOLDING DEVICE. V"

Application filed May 15, 19211. Serial 11'0. 713,612.

being had to the accompanying drawingsand the marks thereon, and which form a part of this specification.

The object of my invention is to provide a shade holding device that can be effectively operated in combination with the adjustable window shade holder now in com mon use, yet to be concealed from view within the room.

Another object is to provide a shade holding device that can be readily installed within the top window pocket of the ordinary window casing, and so designed and arranged as to be adapted to supporting and operating the adjustable shade holder and at the same time conceal the supporting and operating device.

A further object is toy produce a shade holding device that will at all times retain the adjustable shade holder supported therein, in a horizontal position across the window sash.

A still further object is to produce a shade holding device that is simple in construction, easily and efficiently operated and can be manufactured at a low cost.

These several objects are attained under the preferred construction and arrangement of parts more fully hereinafter set forth.

ySimilar parts on all drawings are marked by similar numerals.

I will now describe more fully the detailed construction of my' window shade holding device, referring to the drawings and the marks thereon.

lIhe general construction of my device consists of an elongated roller installed in the top window pocket of the window cas ing, and extending the entire width of the window opening. The roller being so positioned that the front edge thereof lies near the inside face of the window casing cap, and is supported by bearings at either end thereof. Attached to each end of the roller are suspension ropes which are coiled around. the roller, and extend through openings in the top of the window casing, attaching lto the ends of an adjustable shade holder, holding same suspended in the window opening. The roller as installed in the top window pocket, is provided with means for operating same by rotating same on the roller bearings, thus providing means for raising and lowering the adjustable shade holder to any desired position in the window. At the present time it is difficult to secure proper ventilation through the opening of the upper sash of a window, due to the presence of the ordinary window shade mounted in the casing at the top, and which obstructs the free passage of air therethrough. My device is used in combination with an adjustable curtain holder as set forth in a former Patent No. 1,158,677, Nov. 2, 1915, and is a special means for suspending same in the window opening, and provided for a stable, rigid adjustable support for the shade holder, allowing said holder to be placed at any desired position in the window before drawing the shade mounted therein, and providing a clear, und

obstructed opening at the top of the window for ventilation and light.

The roller 1 may be made of any suitable material, as wood or sheet metal, and extends across the entire width of the window opening. Both ends of the roller are provided with pintles Q and 3 which are mounted in the support brackets 4 and 5 The brackets iand 5 are securely attached to the inner face of the window casing cap G Inside the roller 1 at one end thereof, is an operating spring 7 having its inner end attached to the retaining roller 1 and the outer end of said coil spring being attached to the pintle 3 loosely mounted in the end of the roller. The pivot 3 is engaged in a slot in the bracket bearing 5 preventing any rotation of the pivot, and is engaged to the roller only through the ratchet hooks 8 attached thereto. The pintle Q is free to rotate in the bracket bearing The roll construction is similar to the construction of the ordinary spring window shade roller. Small adjustable cord supports Q and 10 are attached to the ends of the roller 1 at the points ll said cords being coiled around the roller drum with a suflicient number of turns to allow for the length of adjustment desired for the supported window shade holder. The cord coils being wound on the roller in such amanner that the free ends pass from the roller over the front side thereof, and near the inner face of the window casing cap. The lower ends of the cord supports are attached to the ends of a window shade holder 12 by a knot in the end of the ropes. A wire frame 20 is adjusted on the roller 1 so as to partially inclose the coiled section of the support cords, for preventing them from loosening or sliding out of place, should the shade holder be raised and remove the weight from the cords. Inside the shade roller holder l2 is mounted the ordinary window shade roller 13 of the spring roller type. This patent does not lay claim to the shade holder l2 or the inclosed window shade 13 but is confined to the operating device for supporting and operatingv the shade holder. The shade roller l3 is also provided with an internal coil spring lta said roller being so designed that the said coil spring will operate the roller 12- and cause it to wind up when released by pulling on the attached shade lll- It is essential to the operating of my device that the coil spring 7-- in the roller 1 be somewhat stronger than the coil spring 14a in the shade roller 13 thus preventing the holding device from operating when it is desired only to operate the shade within the shade holder. The curtain holder 12 is provided with a draw cord 15 attached to the end of the holder, shown in Fig. l, or the cord may be attached to the center of the holder as illustrated in the Fig. 3. The position of the draw cord makes no difference to the invention and is only a matter of choice. In operating my device by pulling on the cord l5 the adjustable shade holder may be raised or lowered as desired, by reason to the action of the coil spring 7 and connecting ratchets 8- in roller l which is concealed in the top window pocket of the window casing, and may raise the shade holder to the top of the window and retain it firmly against the window casing cap, giving the window the appearance of permanently attached window shade. One of the important features about my device is that it is completely concealed within the top window pocket, and also provides a means for lowering the window shade for the purpose of an unobstructed passage for ventilation and fbr light, yet retaining the full use of the window shade.

A modified form of my shade holding device is shown in Figs. 5, 6, 7, and 8. The principle involved is exactly the same as already set forth in the roller described, and the mechanical detail is varied only in the end of the roller 19 by omitting the internal coil spring 7- shown in Fig. 3. The roller 19 is operated by means of the pull cord 16 which is coiled about the end of the roller so as to unwind as the support cords Q and 10 are wound thereon. The weight of the curtain holder 12- is sufficient to unwind the roller A9- when released by the. pull cord 16 thus lowering the shade holder 12 to any desired position. Same is also raised as desired by pulling on the cord 16 thus rewinding the support cords on the roller 19 The cord 16- is passed through a. cam pinch pulley l7 fastened to the outside of the window casing, and which is provided with a self locking device for holding the cord 16 in any position desired. The shade is adjusted in the same manner as described in the preferred form heretofore set forth. Over the coiled section of the

ropes

10 and 16 is also a wire frame 18 inclosing the pull cord with onel of the support cords, and prevents same from loosening and uncoiling should the weight of the shade holder be removed, The center ring a of the wire frame 18 is of a size to allow the roller body 19 to rotate freely therein, while the end rings b are slightly enlarged to slide freely over the coils of the rope, or cord as wound on the roller 1Q- The wire frame is prevented from rotating by the extension of the cords leading from the roller, but the said roller and coils move freely therein as the device is in operation. -The center ring -afd being placed on the roller so as to come between the support cord -10- and the pull cord -16-. It Will be seen that as one cord unwinds, the other cord Winds up on the` roller, causing the frame 1S- to move slightly along the body of the roller, and always in a position to prevent any loosening of the coils should the cord be slackened.

Having fully described my shade holding device, What I claim as my invention and desire to secure by Letters Patent, is:
