Specification of Letters'Patnt.

Patented Nov. 14. 1905i Original application filed August 20,1900, Serial No. 27,490. Divided and application filed August 19, 1901l Serial No. 72,602. Again i divided and this application iiled May 16, 1904. Serial No. 208,187.

To t2/Z whom, it muy concern:

Be it known that I, PLATO G. EMERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois` have invented certain new and useful Improvements in Shade-Guides, of which the following is a specification.

This application is a division of my application, Serial No. 72,602, filed August 19, 1901, which was a division of Vmy original application, Serial No. 27,490, iiled August 20, 1900.

This invention relates to guides for shades operating in frames or casings for windows, doors, o1' other openings, and it has particular reference to means for guiding and holding the shade against the tension of a springroller upon which the shade is mounted.

The object of the invention is to guide the shade so that it will not become disarranged during its adjustment and to hold the shade in its adjusted position against the tension of the spring-roller.

In the accompanying drawings I have illustrated one embodiment of the invention, and, referring thereto, Figure 1 illustrates a shade embodying my invention in a window frame or casing. Fig. 2 is a sectional View of the guiding and holding means at one end of the shade-stick. Fig. 3 is a sectional view on the line 3 3 of Fig. 6. Fig. 4 is a plan view of the head.

Referring to the drawings, 10 is a curtain mounted on a spring-roller 11 in the frame or casing 12 and provided at its lower end with a tubular shade-stick 13, carrying guideheads 14 at its ends, which are arranged to travel in the vertical grooves 15 of the frame or casing. The guide-head extends above and below the end of the shade-stick and is provided with a shank 16, which is arranged in the end of the stick. A spring 17 is arranged on said shank between the end of the stick and the inturned end 18 of a sleeve 19, which incloses the spring and the end of the stick..

A frictionl holdingdevice or shoe 22 is elastically connected with thehead by a spring 23, arranged on the shank 24 to bear against said friction device and the head. The friction device is carried by a rod 25, which may or may not be connected with a pinch-handle or other operating device at or about the middle of the stick.

The guiding and holding means will generally be duplicated at each end of the stick, although it is not essential that they should be the same.

In practice the bearings of the head and the friction-shoes are arranged normally to make contact with the frame or casing, and the friction-shoe is mounted so that the same may have yielding body movement independent of the guide, which is yieldably connected with the stick. The friction member can be moved bodily toward the outer edge of the head to release the shade by operating the pinch-handle, and after the shade is adjusted the spring 23 will move the friction device bodily from the outer edge of the head into engagement with the frame or casing to hold the shade in its adjusted position.

Without limiting myself to the exact construction and arrangement of parts herein shown and described, whatI claim, and desire to secure by Letters Patent, is-

la In a curtain fixture, the combination with a window-frame, a spring-actuated shade and a shade-stick, of heads carried by the stick, springs tending to force said heads outwardly, rollers carried by said heads, and friction-shoes elastically connected with said heads, said rollers and said shoes being arranged normally to contact with the windowframe, substantially as described.

2. In a curtain-fixture, the combination with heads, outwardly-thrusting springs acting upon said heads, antifriction-surfaces carried by said heads, friction-shoes elastically connected with said heads, said antifrictionsurfaces and said shoes being arranged normally to make contact with the window-frame, substantially as described.

3. In a curtain-holding device, the combination with a shade-stick, of a guide yieldably connected therewith, a friction holding device in said guide, and means for mounting said friction holding device so that the same may have an independent, yielding body movement toward and from the edge of the guide.

IOO

4. In a curtain-holding device, the combination with a shade-stick, of heads carried thereby, springs for normally thrusting said heads outwardly, curved bearings at the ends of the heads adapted to normally contact with the window-frame, and a yielding friction member connected to the head between said end bearings, said friction member being adapted for bodily movement toward and from the outer edge of the head, substantially as described.

5. 1n a curtain-fixture, the combination of a shade-stick, slidable rods arranged within the stick, heads at the ends of said stick, anti.- friction-surfaces at the ends of said heads, friction-shoes, springs interposed between the shoes and the heads for forcing the shoes and outward.
