GUIDE FOR WINDOW-SHADES.

Specification of `Lett-ers IEatent.l

Yjlvttented Feb. 27, 1917.

Original application 1ed March 2, 1915, Serial No. 11,640. Divided and this application filed September 9, 1915. Serial N0. 49,677.

To all whom t may concern.'

Be it known Athat I, ALEXANDER ZoRBA, a

citizen of the United States of America, residing at Herrick, in the county of Gregory and State of South Dakota, have invented certain new and useful Improvements in Guides for Window-Shades, of which the following is a specification.

This invention relates to guides for window shades, and it has for its object the provision of an improved device of this character which will be simple and inexpensive in construction, may be attached yin a few minutes time and when in position will not only cause the shade to run true upon the roller but will also limit the movementof the shade both at the top and bottom as it travels, so that at the top of its travel it will not be Ipermitted to run upon the roller to jam the window stick between the roller and the window frame and at the bottom of its travel will be prevented from coming in contact with the window sill.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawings:

Figure l is a front elevation of a window having my attachment supplied thereto and Fig. 2 is a perspective view of the guide and associated parts.

Like numerals designate corresponding parts in both of the gures of the drawings.

The subject matter of the present applicationis divided from my copending application, Serial No. 11,640 filed on the 2nd day of March, 1915, which became Patent Neiasosi, issued Aprii 25, 191e.

In the drawings, 5 designates a window frame of usual construction, 6 a shade roller and 7 a shade. The ends of the shade stick 8 are reinforced by sheathings 9 and these sheathings carry stems 10 having balls 11 upon their outer ends. These balls are disposed to travel 'in tubular guides l2 secured by ears 13 and screws 14: to the window frame. These guides have slots 15 formed in their inner sides through which the stems 10 pass and in which said stems travel. The slots 15 terminate short of the `bottom of the tubular guide as indicated in Fig. 2 at 16. It will therefore be apparent that the downward movement of the shade is limited by the stems 10 contacting with the bottoms of the slots 15. Caps 17 having knurled portions 18 to provide for their convenient manipulation are threaded upon the upper end of the tubular guide at 19, and these caps 'limit the upward movement of the shade to thereby prevent the shade stick 8, and the lower portion of the shade from being jammed between the shade roller 6 and the window frame while the provision of the balls 11 prevent lateral movement of the shade stick and the lower portion of the shade and causes the shade to run true upon the roller 6, while at the same time the movement .of the shade is limited both at the top and the bottom of its travel.

While the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as maybe made within the scope of the appended claims.

Having described my invention, what I claim is:

1. A guide for window shades comprising a hollow, cylindrical, elongated shell having a slot formedl in one of its sides which opens at the top of said shell but terminates short of the bottom thereof, a guide member comprising a shank which passes through said slot and an enlarged head which lies and travels within said shell, means for securing said member to a shade stick and a cap screwed upon the upper end of the shell the lower edge of which overlies and prevents said shank from passing out of said slot until said cap is removed.

2. A device of the character described comprising in combination a shade and its stick, a member embracing the end of the shade stick, a shank carried by said member, an enlarged head carried by said shank, a slotted, cylindrical shell having a slot formed in its wall through which said shank passes and which slot terminates short of the bottom of said shell a suicient distance to prevent the lower edge of the shade from coming into contact with the window sill when the shade is drawn down to its limit of vmovement anda cap threaded upon the upper end of said shell the lower edge of which overlies said shank and limits the upward movement of said shade. i

3. A device of the character described comprising in combination a shade and its shells and thereby limiting stick, headed members projecting in longitudinal alinement with and beyond the opposite ends of the shade stick, low, cylindrical shells one disposed at each side of said shade said shells having slots formed in their sides which are disposed toward the shade and through'whieh slots said headed members extend with their heads disposed Within said shells7 said slots terminating short of the bottoms of said the downward Copies of this patent may be obtained for a pair of holmovement of the shades and caps upon the upper ends of said shells and closing the upper ends of said slots and by which the upward movement of the shade is limited.

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