To all 'whom lit may concern: l, forin of the invention shown in Fig. 1 each of Be it known that I, DALE VHINERY, a these rollers comprises an oval or oblong` citizen of the United States, residing at i shaped ring 13,- the opening oi' aperture 14- Hoboken, in the county of Hudson and l of which has the saine shape or outline as 3 State of New Jersey, have invented certain i, its periphery and engages a cross-pin 15 in 60 new and useful Improvements in Shadethe head. Surrounding the ring is acirculai Y Fixtures, of which the following is a speciii l elastic ring or tire 16 which ma be formed cation. l of a thin strip of resilient metal, this latter struction and combination of n,

55 engaging ro connection with car windows. The lower or free ends of shades of this class are provided with devices adapted to enter guide-ways in the sides of the window-frame to guide the shades during .1 the adjustment thereof vxiid to engage said Ides in positions of guide-ways to hold the sh adjustment. .w

The object ofthe invention is to provide a simple and etiicient holding and guiding dev'ice to guide the shades during the vadjustment thereof, and to hold tirshade in position for adjustment. The invention consists in th" novel condiereinafter fully described and clainie The principle of the invention is illust ated in the-accompanying drawings, whereinlq,

Figure 1 is a side elevation, partly in seictioii 'of a portion of a window frame, a sha e, and a holding device therefor eni'. bodying the invention; Fig. 2 lis a detail, partly in section, showing a modification; and Fig. 3 isa view similar to Fig. 2, illustrating a further modification.

Referring to the drawings, 5 designates the usual guide-grooves in the sides of the window-frame, and 6 the lower portion of a spring-actuated shade.

7 designates the usual tubular curtain stick secured in a pocket S formed in and across the lower end of `the shade, within which curtain stick are the usual oppositely disposed rods 9 normally forced apart by a spring 10 located between their inner oposed ends, said rods being provided with the 'usual pinch-handles 11, by which the rods may be drawn toward eachother in opposition to the spring 10 to release the s ade, in a manner well understood.

The outer projecting ends of the rods 9 are provided with shoes 12 disposed at right anglesto *the rods and arranged within the guide-ways 5, said shoesbeiiig substantially ehannele-shapled to accommodate the guideers mounted therein. In the This invention relates to spring-actuated constituting the guide-engaging surface of shades adapted foruse 1n the roller.

roller spring tends to raise the fixture in its guidegroove, such raising tendencybeing resisted during each half revolution of the rollers by the constantly increasing radius between the center of the pin 15 and the point o the periphery of the elastic ring 16, which is contacting the guide-groove during the first half of each half revolution. The resiliency or elasticity of the circular ring 16 causes it to flatten slightly as the llat sides of the ring 13 come opposite the base of the guide-groove, ally or yieldingly retained against the upward pull of the shade roller spring, and

whereby the outward thrust of the ends ofV the fixture against the guide-grooves is opposed by an elastic or yielding resistance which maintains the ixture always in snug engagement with the groove and prevents rattling, noise and wearing loose of t ie parts.

described, the elastic resistance to the out ward thrust of the fixture heads being effective during the engagement of the narrow or pointed portion of the roller with the l guide, at which time the pin 15 tends to crowd and force the spring 17 into the narrow end of the opening 14a.

Fig. 3 shows a still further modification wherein a substantially oval or oblong@v shaped ring 13", Similar to the ring 13, is einploy-ed; while the circularspring ring 17 of Fig. 2 is substituted by a sinall coil compression spring 1S that seats in a notch 13c in the inner periphery of the ring 13b and at its other end bears against a wearing ring 19 on 110 whereby the fixture is elasticor f i Y '898947 the bea-ring spindle 20. The principle Vand manner of operationl of this forni is substantially identical withtht of Fig. '2.

It is Obvious that the principle of the invent-ion might be embodied in still other specific forms; and hence I do not limit the ini vention to the particular form shown, except to the extent indicatedin'specie claims.
