SHADE-GUIDE.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Original application iiled August 20, 1900, Serial No. 27,490. Divided and this application led August 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 Shade-Guides, of which the following is a specification.

This invention relates to novel improve ments in shade guides and has particular reference to means for guiding and holding the shade against the tension of a spring roller upon which the shade is mounted.

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

The invention consists essentially of guiding devices carried by the shade stick and traveling in grooves a casing and an independent friction device for holding the shade in its adjusted position against the tension of the spring roller, the friction device being operable `to permit the ordinary adjustment of the shade without affecting the guiding device, and being capable of operation to release the guiding device so that the shade may be disengaged from the easing for cleaning and other purposes.

In the accompanying drawings Figure 1 illustrates a shade embodying my invention in a window casing. Fig. 2 is a sectional view of the guiding and holding means on one end of the stick. Fig. 3 shows a guiding device provided with ball bearings at the ends of the shoe. Fig. 4 is a sectional view on the line CD of Fig. 3. Figs. 5 and 6 show a modified construction of the invention Fig. 5 being a front view and Fig. 6 a vertical sectional view. Figs. 7 and 8 are details showing the manner of arranging the rollers in the friction shoe illustrated in Fig. 6, Fig. 7 being a sectional view on the line 6-6 of Fig. 6. Fig. 9 is a sectional view on the line E-F of Fig. 6.

Referring to the drawing, in which like numerals of reference denote corresponding parts in the several figures, 10 designates the curtain of my improved window shade which is attached to the spring roller 1l in the usual manner and provided at its lower end with a tubular shade stick 12 carrying guiding devices 13 at its ends which are arranged t0 travel in the vertical grooves 1-1 in the casing 15.

The guiding device consists of an elongated guide shoe 1G provided with a hollow shank 17 which is arranged to operate loosely in the end of the shade stick 12 and to hold it in the groove of the casing in operative position I provide a spring 18 which is arranged within the stick and bears against the inner end of said shank and against a stop 19 located within the stick. In order to provide an adjustment for the guiding device so that it can be adapted to casings which vary more or less in width I make the stop 19 in the form of a peripherally threaded disk to screw into the threaded section 20 of the stick which is formed by making an annular depression 21 on the outside thereof. The stop device can therefore be adjusted lengthwise of the stick to control the tension of the spring and can be tightened or loosened as it may be desired to increase or decrease the tension of said spring as well as to obtain the proper normal position of the guiding shoe with relation to the end of the stick.

At the ends of the guide shoe I provide anti-friction devices which may consist of rollers 22 journaled in the sides of the guide shoe, as shown in Fig. 2, or loosely arranged in the guide shoe, as shown in Figs. 6, 7, and 8, or I may employ a ball-bearing, as shown in Figs. 3 and 4.

In Figs. 7 and 8 the rollers 23 are held within the guide shoe by means of the inwardly turned langes 24 on the sides 25 and these rollers are arranged to engage with each other and with the friction device, as shown in Fig. G.

In Figs. 3 and I I have shown the guide shoe provided at each end with a race 2G for a series, of anti-friction balls 27 which project beyond the face of the guide shoe so as to bear against the back wall of the groove. The guide shoe in this instance is formed of sheet metal bent or stamped to form two leaves 28, 29, spread apart throu'ghout the middle portion to accommodate the friction device and drawn together at their upper and lower ends and secured by a screw or rivet 30. The ball race encircles this screw or rivet and is formed by depressing each of the leaves of the shoe to provide a continuous groove therein which will hold the balls loosely and yet prevent them from falling out.

The invention is not limited to the use of anti-friction devices of any particular kind and others may be employed besides the three species shown and described.

The friction device consists of a foot 31 which is provided with a hollow shank 32 and is normally held in operative position by means of a spring 33 which bears against the inner end of the shank and against the stop 19. The foot of the friction device may be of any suitable shape or configuration and it is constructed to engage the guide shoe to press said shoe against the tension of its spring 18 when it is desired to release the guide shoe from operative position in the groove. The friction foot is operated by means of a pinch handle 34 which has an integral broadened outer portion 34, and an enlarged head 347 and a reduced neck 34 (Fig. 9). The head is adapted to be inserted through the slot 35 in the stick and i turned transversely thereof into operative position in the stick and is carried by a rod 36 which enters the hollow shank of the fric'- tion foot and is provided with a head 37 which enga-ges a shoulder 38, said head being shown screw threaded on the rod but it may be rigid therewith as shown in Fig. 3. The pinch handle has a screw threaded eng-agement with the end of the rod so that it can be adjusted longitudinally of the stick to obtain the proper adjustment for the fric'- tion foot. A nut 39 is fixed on the inner end of the rod to limit the adjustment, and when it is desired to take the fixture apart this nut is held rigid, while the rod is being turned, by means of a tool inserted through the slot 35 and into a slot 4() in the side of said nut.

In Fig. 6 I have shown a modified construction of my invention in which the guide shoe spring 18 is arranged on the shank 17 to bear against the end of the stick proper 12 and the inturned end 41 of a sleeve 42 inclosing the spring and the end of the stick, and the friction foot spring 33 is arranged on the shank 32 to bear against the foot 31 and the guide shoe. The operation of the parts in this construction is precisely similar to that shown in Fig. 2 and the arrangement of the spring, is to all intents and purposes, the same.

This invention provides simple and effective means for holding and guiding a shade under tension which do not easily get out of order and which can be manipulated to adjust the shade without affecting the guiding devices or by further operating the friction device the guiding devices may be adjusted so that they can be readily disengaged from the grooves. The guiding device a-nd the friction device are lyiel-din'gly mounted and normally arranged to operate independently of each other so that in the ordinary use of the shade the guiding devices will be undisturbed, but when it is desired to clean the shade or to withdraw it from its guided position for any other purpose, the friction foot is further withdrawn to release the guiding device from engagement with the wall of the groove. My invention, therefore, toa very large extent prevents the accidental withdrawal of the guiding devices from the grooves as under all ordinary conditions it will simply be necessary to release the fricti'onal engagement of the foot with the wall of the groove, whereupon the spring roller immediately operates to roll up the shade withoutcausing the friction foot to engage the guiding device.

I do not claim broadly herein a yielding stop for the guiding device as this is claimed in my Patent No. 716,832 granted December 23, 1902, of the appli-cation for which this aplication is a divisi-on.
