WINDOW-SHADE HOLDER.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed September 18, 1912. Serial No. 721,057.

To all whom it may concern Be it known that I, Joserrr PETRITSCH, a citizen of the United States of America, residing at Chicago-Heights, in the county of 5 Cook and State of Illinois, have invented certain new and useful Improvements in Window-Shade Holders, of which the following is a specification.

' This invention relates to adjustable win- 10 dow shade holders and the object of the invention is to provide means for supporting the shade which will protect the means for making the shade adjustable.

Another object of the invention is to provide a shade holder held between the j ambs of a window which holder is adjustable but which requires no special means for keeping its adjusted position.

A further object of the invention is to provide a novel arrangement of supporting cords which will permit the shade to move vertically but will prevent horizontal swinging and tilting of the ends of the shades.

With these and other objects in view the invention consists of certain novel constructions, combinations and arrangement of parts as will be hereafter described and claimed.

In the drawings, Figure 1 shows a front elevation of a window frame with my improved shade holder applied thereto. Fig. 2 is a vertical transverse section taken on the line 22 of Fig. 1. Fig. 3 is a horizontal section taken on the line 33 of Fig. 1. Fig. 4: is an enlarged detail view of the bracket and pulley and cords associated therewith. Fig. 5 is a front elevation of a window frame having attached thereto a modified form of my invention, and Fig. 6 is a detailed section taken through the telescoping supporting means for the shade in the modified form. Fig. 7 is an enlarged vertical sectional view on line 77 of Fig. 6.

Like characters of reference designate similar parts throughout the several views.

I-Ieretofore, window shade supporting devices have been objectionable in that they have not been securely fastened to the jambs of the window frame. Other objections to the present forms are, thatthere is usually a counterweight or a spring for the purpose of holding the shade holder in any fixed position, a cord sometimes being made use of when counterweights or springs are. not used. These cords for the purpose of bold ing the window shade roller in any fixed posltlon are generally exposed and if for any reason, made possible by their exposure,

they are not severed the shade and shade.

holder will be disabled. My invention aims to overcome these objections by providing 1n the jambs of the window frame suitable channel members which are designed to guide the shade holder and also to house the cords'which allow the shade holder to be moved to adjustable positions.

The drawings show two forms of the invention, but it is to be understood that slight changes such as are necessary to aflix my invention to various types of window jambs will be well'within the scope of the invention.

Referring to the drawings, it will be seen that each side of the window frame has secured thereto a vertical channel member 1,

the strips being made of suitable material such as aluminum, iron, copper, brass, or in fact any suitable material which will be at once sufficiently strong to stand the strains to which the channel member may be subjected and at the same time of a pleasing appearance. Among the objects for using this channel member, are the provision of guiding means for the shade holder and housing means for the cords, so that any form of channel member could be used, but as shown, particularly in. Fig. 3, I prefer to have the flanges 2, bent inwardly toward one another. The shade holding form which is used in conjunction with the channel members may be made of a single channel member, but I prefer to use adjustable channel members, although this construction is obviously not necessary. As shown in the drawings, there is provided a central section 3, made of any suitable material, and hollow to receive telescoping sections 4 and 5, the said sections being also hollow for the purposes hereinafter indicated. The sections 4 and 5 have mounted upon their outer ends respectively, pulleys 6 and 7, which pulleys are suitably journaled in their respective sections and adapted to receive the shadesupporting cords to be referred to hereinafter, it being entirely within the. scope of the invention to form the rollers large enough to take the requisite number of cords or'to provide a separate roller for each cord. The outer ends of the sections 4 and 5 each carry a shade hanger 8, between which is mounted in the usual manner a shade 9, this shade being in every respect similar to the ordinary shades in use.

Secured as at any suitable point 10, in one of the channel members 1 is a flexible rope or cord 11, which is trained over the upper part of the pulley 6, through the sections 4c, 3, and 5 respectively to the lower surface of the pulley 7 and from thence is led upwardly and fixed as at 12 to the upper end of the other of the channel members. Secured in the lower end of the last mentioned channel member as at 13, is a second cord 14:, which is led upwardly over the pulley 7, through the sections 5, 3, and 4: respectively under the pulley 6 and is led upwardly and fixed to the upper end of the first mentioned of the channel members 1 at a suitable point such as 15. These cords 11 and 14: may be made of the ordinary flexible cord or rope, or they may be made of metal in the form of flat chains or hands, the cords being made suiliciently flexible to admit of an easy movement of the shade holder.

Secured at a point preferably central of the section 3, is a lifting cord 16, which is adapted to pass over a pulley 17, and hang downwardly to present an accessible end 18. The pulley 17 may be provided with any of the ordinary retaining means for holding the shade holder in any desired position, this retaining means forming no part whatever of the present invention.

In the operation of the form of the invention already described, it will be noted that when it is desired to lift the shade for instance, the end 18 of the cord 16 will be pulled down as usual, which will be accompanied by the raising of the sections 3, 4 and 5, and the consequent passing of the pulleys 7 and 8 over a part of the cords 11 and 1%. Evidently, it will not be possible for one end of the shade holder to be raised higher than the other end when the cords are once adjusted, inasmuch as this would require that the cords be stretched, but it is presumed that the cords will not yield sufficiently for this.

Fig. 3 shows one end of the adjust-able holder, but it will be understood from this figure that the outer end of each. of the sections which slidably engage the central section 8 passes into the adjacent channel member 1, so that lateral movement of the holder is prevented and the shade and holder therefore move smoothly between the channel members 1.

The upper and lower surfaces of the outer ends of the members 4 and 5 respectively, are provided with slots 15), through which the cords pass, these slots 19 being preferably no deeper than the depth of the flanges 2, formed on the channel members 1, although I do not wish to be limited to this construction (see Figs. 3 and 4).

In the modified form of the invention shown in Fig. 5, the only change made over the preferred form is that the section 3 has pivoted in the central portion thereof a pair of rollers 20 and 21. In this form of the invention, one cord 22 is secured in the channel member 1, preferably in the lower part thereof as at 10 and extends upwardly over the pulley 6, which is identical with the pulley 6 of the preferred form, through the section 4 and under pulley 20, from whence it is led upwardly to any suitable securing means 23. The other cord Q-l secured as at 13 in the lower end of the opposite channel member is led upwardly over pulley 7 comparable with pulley 7 of the preferred form and through section 5 under the pulley 21 and upwardly to the securing means 23, the cords and pulleys on each half of the window being symmetrical. The manner of operation of this form is identical with that of the preferred form, the only material difference being that part of the supporting cords are not protected by the channel members 1, but it will be noted that the unprotected port-ions of the cords in the modified form are near the upper part of the window where they will be out of reach and danger. As in the preferred form, it is not necessary to supply set screws or any means for fastening the telescoping sections t and 5 with the section 3, inasmuch as the cords serve to hold these respective parts suiiiciently rigid, although set screws can be used if desired, as shown in the drawings.

What I claim is:

1. In a window shade holder, a horizontal channel hanger adapted to hold the window shade, vertical channel guides adjacent the ends of the horizontal channel member, and flexible shade supporting means secured to the vertical channel members and passing through the vertical and horizontal channels.

2. In a window shade holder, a channel hanger, channel guides, pulleys mounted in the ends of the channel hanger, and flexible supporting members engaging the pulleys and contained within the'channel members.

3. In a window shade holder, a vertical movable channel hanger, guide channels adjacent the ends of the hanger, the ends of the hanger sliding within the guide channels, pulleys mounted in the ends of the hanger, and supporting flexible members secured in the guides and passing over the rollers and through the horizontal channel hanger whereby the flexible member is completely housed.

4. In an adjustable shade hanger, telescoping channel hangers, guide channels adapted to receive the ends of the telescoping channels, shade supporting brackets secured to the ends of the hanger, and means for supporting the hanger passing through the channel hanger whereby the brackets are held adjacent the ends of the shade.

5. In an adjustable shade hanger, telescoping channel hangers, guide channels adapted to receive the ends of the telescoping channels, shade supporting brackets secured to the ends of the hangers, pulleys mounted in the ends of the hanger, and flexible supporting means secured to the guide channels and engaging the pulleys, whereby the Weight of the shade draws the brackets together.

6. In a shade hanger, a channel hanger adapted to support a shade, a pulley mounted in each end, channel guides adjacent each end of the hanger, a flexible supporting means secured in the top of each guide channel, said flexible member passing under the pulley adjacent the guide in which said flexible member is secured and over the other pulley and secured to the lower end of the other guide member. 7

In testimony whereof I aflix my signature in presence of two witnesses.
