ALAMEDA, CALIFORNIA ROLLER SHADE GUIDE AND HOLDER Application filed July 29,

This invention relates particularly to an apparatus for confining a window shade to movement in a predetermined path over a window opening or other analogous enclo- 5 sure.

An object of the invention is to provide a pair of parallel guide members on opposite sides of a window frame to which means on a'window shade may be slidably guided 0 for controlling the movement of the window shade in a predetermined path over the window frame, and for preventing the edges of the shade from dropping or sagging from the Weight of the shade.

15 A further object of the invention is to provide a support and guide for roller windows that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and facility and convenience in use and general efficiency.

Other objects and advantageswill appear as this description progresses.

In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

In the accompanying one sheet of drawings:

Fig. 1 represents a front elevation, from 0 the inside, of a window frame having a roller shade mounted thereon on a guide device constructed in accordance with my invention.

Fig. 2 is a vertical section taken through Fig. 1 on the line 2-2.

Fig. 3 is a cross section taken through Fig. 1 on the line 33.

Considerable difficulty has been encountered in holding a window shade in a drawn position parallel to the face of that type of window sash which opens into either a vertical, or horizontal angular position in a window frame. On a sash made to swing into an angular position, a window shade mounted thereon would in a drawn position tend to sag of its own weight. My invention con- 1931. Serial No. 553,797.

templates a guiding apparatus, which is mounted on the opposite side stiles of a Window sash, to receive the opposite side edges of a window shade therein, whereby the edges of said shade will be prevented from sagging from the weight of the said sash, and at all timesthe shade will be supported in a substantially planar position.

In detail, the construction illustrated in the drawing comprises a window frame generally designated by the numeral 1, having a sash 2 therein, slidably and pivotally connected to opposite sides of the window frame by the sash supporting arms 3. I do not Wish to limit myself to any particular form of sash supporting and controlling mechanism, as I am awarethere are many types of such apparatuses for operating and controlling sashes in a swinging position.

A window shade 4, mounted on a spring roller 5, is secured to the inside face of the sash on each of the opposite stiles by'the spaced brackets 6 and 7. An end of the shade i has a pull string 8, extended around a cam roller 9 secured on an end rail 10 of the sash, to draw the shade over the sash and hold it by means of a cam roller,- in any selected position. lVhile the cam roller 9 is commonly used to hold a shade in a drawn position on a sash which is stationary or which slides in a vertical or horizontal plane, or which. swings in vertical or horizontal plane, I have found that'the cam roller is essentially necessary to a shade arranged on a horizontally swinging sash, such as I haveindicated inmy drawing, to obtain an efficient operation of the shade. 1

In order to :hold the opposite side edges of the window shade 4c in close proximity to the inside face of theopposite side'stiles of the sash 2, I arrange a pair of U shaped brackets 9-10 and 1112 on each of the said oppo site stiles of the sash. enthe inside face thereof. adjacent each of the opposite end rails of the sash. ihe U shaped brackets are arranged so that one leg 13 thereof may be fastened to the face of the sash by means of fastening screws 14. The opposite leg 15 of each of the brackets is bended or arranged in some desirable manner to receive and support an end of the guide members 16-1 6. Although I have shown each of the gu de members 16-16 to be a wire or rod having the opposite ends looped over or headed and 5 enlarged to be received in the sockets 15' formed on the ends of the bracket legs 15, it is to be understood that a non-extensible ribbon guide might be substituted in lieu of the wire or rod 16 or 16. The respective pairs of brackets 910 and 1112 are each arranged on opposite stiles of the sash on a line substantially parallel to the edges of the window shade when in the drawn position, so that the legs 15 on each 15 bracket are in substantial alignment and the guide members 16--16 will be in parallel alignment with the side edges of the window shade.

The respective pairs of U shaped brackets 8 9-40 and 11-12, together with the connecting guide members 1616, are so arranged that the window shade 4 will be received between the projecting legs 15 of the said brackets, and the inside face of the sash 2. Thus when the window shade 4 is placed into a drawn position on the window sash 2, the shade edges Will be confined between the respective brackets and the guide members 16--16, and the edges of said shade 4 will "be so supported that the weight of the said shade will not cause it to sag or droop when the sash is swung into any angular open or closed position. The sash guiding and supporting apparatus will guide a window shade on a sash in a true manner, and because sagging or dropping of the shade is prevented, the sash life is prolonged, and in moving the shade into and from the drawn and rolled positions it is subjected to a minimum of 4. abuse.

Having thus described this invention, what I claim and desire to secure by Letters Patcut is:

1. A window guide to support a side edge of a Window shade comprised of a bar having a head formed on each of its opposite ends; and a bracket arranged adjacent each of the V opposite ends of the bar, each bracket having a socket therein in which one of the opposite enlarged heads of the bar is confined.

2. A guide to support a side leg of a window shade comprised of a pair of U shaped brackets, each bracket having one leg thereof arranged for attachment to a shade support and the other leg provided with a socket therein, said bracket being spaced apart and connected by a guide member, having an enlarged head on each of its opposite ends that is confined in the bracket sockets, to guide the window shade thereon.

In testimony whereof, I have hereunto set my hand at San Francisco, Calif., this 1st day of July, 1931.

THOMAS E. MGNULTY.
