Original application led October 3,1900, Serial No. 31,895. Divided and this application filed January 26, 1903. Serial No. 140,573.

To all whom it may 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 Shades, of which the following is a specification. Y

This invention relates to improvements in `shades for windows, doors, and other open.

means wholly within the shade-stick and construct it so that its tension will be overcome by force applied to raise and lower the shade in the usual manner.

In the accompanying drawings, Figure 1 illustrates my invention embodied in a window-shade and is shown partly in section. Fig. 2 is a longitudinal sectional view of a part of the shade-stick and showing the clamping device. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2. Figs. 4 and 5 are detail views of parts shown in Figs. 2 and 3. Fig. 6 shows the clamping device located at one end of the stick, which is partly in sec- Figs. 7 and 8 are transverse sectional views illustrating different ways in which the clamping device may be constructed.

Referring to the drawings, 10 designates' the curtain of my improved shade, mounted ,on a spring-roller 11 in a window-frame 12,

and provided with a ho1low shade-stick 13,

through which pass the squaring-cords 14.. I-

have chosen to illustrate my invention in this manner Jfor the purpose of convenience and as showing, perhaps,l the principal form in which the invention will be used; but I do not restrict the invention to the use of a springroller for giving the shade an upward tendency nor to the use of separate squaring-cords having their ends attached to the frame at diagonally opposite points,as shown, and the shade may be mounted in a frame or casing of any suitable character for windows; doors, or other openings.

vThe'shade-stick is preferably made in rectangular form in cross-section, as shown in Figs. 3, 7 ,and 8; but other forms can be used andV the clamping device correspondingly` shaped without departing from my invention.

lThe clamping device comprises a member 15 and a yielding member 16, located within the stick and'held in a suitable manner against endwise movement.A In Figs. 2 and 3 I have shown the member 15 supported by a removable plate 17, which is arranged to fit in an opening 18 in the stick and has its ends 19 struck up to rest within the stick upon the end walls of the opening and providing shoulders 20 to abut against said end walls, which form stops, preventing endwise move,- ment of the plate. A pair of screws 21. have threaded engagement with the member 15 and are provided with radial flanges 22 interj mediate of their ends for resting upon the are anchored to the plate 17, and they can be readily operated to adjust said clamping member without removing any of the parts. The yielding member is shown held against endwise movement by stop-lugs 25, struck down from the stick, and this member of the clamping device is constantly under tension oi' a spring 26, located between itself and the wall of the stick. I may use a leaf-spring, as shown in Fig. 2, or a coil-spring 26', as shown in Figs. 7 and 8, and more than one spring may be employed if necessary to provide sufcient tension.

The clamping device illustrated in Fig. 2

atlorded by the spring-roller or other means.

I may, however, locate the clamping device at any point in the shade-stick and employ one or more, as desired. In Fig. 6 I have shown a clamping device embodied with the cord-guide at the end ofV the stick. This Aclamping device is in all respects the same as that shown in Fig. 2; but the figure shows another way of securing the device in the stick. The cord-guide 27 is arranged in the IOO end of the stick and has a top plate 28 and a bottom plate 29 integral or otherwise connected therewith and projecting-into the stick, with their ends 3() inwardly turned. 'I` he clamping members are retained in place against end wise movement between the cordguide and the ends ot' the top and bottom plates, and the screws for the adjustable members have their heads seated in openings in the bottom plate 29, which in this respect corresponds to all intents and purposes with the plate 17 shown in Fig. 2. Openings 31 are provided in the stick, so that access can be had to the screws for adjusting the member 15. A leaf-spring 26 is arranged between the yielding member 16 and the top plate 28, as in Fig. 2; but one or more coiled springs may be used. Instead of the two adjusting-screws shown in Figs. 2, 6 I may obviously use one screw at the middle ot the adjustable member or some other suitable adjusting device, and ot' course I may reverse the relative position of the members or arrange them side by side.

The clamping device may be constructed to engage both of the cords, as shown in Fig. 3; but it will ordinarily be suiicient to clamp only one of the cords. and the clamping members may be constructed with this end in view. In Fig. 7 I have shown clamping members 15 16/ with their adjacent faces rabbeted, one deeper than the other` so that only the cord 14' will be clamped. In Fig. 8 I have also shown a construction tor clamping one ot the cords, the stick being divided by a partition 32 into a compartment 33 for the cord 14C and a compartment 35, in which the other cord 14 and the clamping members 15 16 are located, these clamping members operating only upon the single cord 14C Any ot the clamping devices can be used with the divided stick.

The operation of the invention will be readily apparent from an inspection of the drawings, and it will be understood that the ten-y sion ot' the clamping device is regulated by adjusting the member 15 to hold the shade against its upward tendency; but when force is applied to raise or lower the shade in the usual manner the tension oi' the clamping device will be overcome and permit adjustment of the shade. The clamping device is concealed within the stick, and while it cannot be tampered with it is still arranged for easy adjustment by the proper persons. In this construction I dispense entirely with handles or devices ot' any kind for releasing the clamping device, which greatly simplifies the construction and operation and also provides a restraining device which is not apt to get out ot' order through carelessness or unskilul handling. The use of a device of this character avoids the necessity ot' keeping the squaringcords taut and giving the shade constant attention for this purpose, and besides the wear on the cords and guides is greatly reduced.

In the construction ol theJ invention as shown in the drawings and heretot'ore described I have referred to the clamping devices as comprisinga. yielding member and an adjustable member; but l do notlimit the invention to this specitic (amstruetion and would have it understood that l reserve the right to make all changes which tairly come within the scope of the invention.
