SHADE-ROLLER.
Application filed August 28, 1919. Serial No. 320,351.
To all whom it may 0012061 11 Be it known that I, DOCK- G. HORTON, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Shade-Rollers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to spring wound rollers for window shades and has for one object to provide a novel substitute forthe usual ratchet mechanism thereof, so con structed as to arrest rapid winding ofthe roller in case it is accidentally released, thereby preventing the shade from being entirely rolled up as now often occurs.
A further object is to provide a simple, inexpensive, durable and'reliable sheet metal roller having novel construction for holding several of the interior working parts in place, as well as the shade.
With the foregoing in view the invention resides in the novel construction and arrangement of parts hereinafter fully described and claimed, the,descriptive matter being supplemented by the accompanying drawing which forms a part of this application.
Figure 1 is a longitudinal section of a shade roller constructed in accordance with my invention.
Figs. 2 and 3 are transverse sections on the planes of lines 2-2 and 3-3 of Fig. 1.
Fig. 4 is a perspective view of the nonrotating pintle and the head carried. thereby.
Fig. 5 is a plan viewv of part of the metal blank from which the roller is constructed.
In the drawing above briefly described, the numeral 1 designates the preferably sheet metal shell of the roller, the ends of said shell being crimped at 2 around the edges of two end members 3 and 4, said member 3 having an opening 5 while the member 4 carries the cylindrical pintle 6 of the roller. The non-rotating or flat pintle 7 is rounded at its inner end as seen at 8 and is received in the opening 5, said pintle extending from a head 9 having a notch 10 in its periphery receiving a ball 11 which travels on an annular brake sur face within the roller, said surface being preferably formed by the inner side of an annular flange 12 which extends from the end member 3.
' The notch 10 is provided with an inclined side 13 which converges with respect to the flange or brake surface 12, and the ball 11, although beingof such size as to roll freely on said flange or surface when the shade is being wound or unwound, either slowly or rapidly, is sufficiently large to wedge between the sides 13 and said flange or surface, if the shade roller quickly moves in shade-winding direction. Thus, when the shade has been raised or lowered to the proper extent, a sudden upward movement thereof will dispose the ball to active position so as to hold the roller against further movement until required. Should the shade be accidentally released, the sudden quick movement of the roller will throw the ball 11 to. locking position and thus the roller cannot entirely wind the shade thereon as now often occurs with the common types of rollers.
The usual spring 14 is positioned in the roller and at 15 is passed through an opening in head 9 and seated in a groove 15, While the other end of said spring has a suitable connection with the roller. In the present showing, this spring is attached at 16 to a disk 17 in the shelll, said disk ing a peripheral notch 18 receiving an internal rib 19 which extends longitudinally of said shell. meeting edges of the metal sheet of which the shell is constructed, and said edges may well overlap for a part of their length. as seen in Fig. 2 to form an anchorage "for the upper end of the shade 20. A rod 21 passes longitudinally through the spring 14 to prevent bowing 0f thelatter, one end of said rod fitting into a socket 22 in the head .9
i Specification of Letters Patent. 7 Patented Sept. 7, Tid /3G.
The rib 19 is formed at the while the other end passes loosely through. a
central opening in the disk 17, the latter being held in place by a cotter pin or the like 23. A The rod 21 is provided with a lateral flange 24 which retains the ball 11 in the notch 10, and said flange may well be formed by a washer held in place by the spring 14.
When the shadeis pulled downwardly, all parts rotate except the pintle 7, the head 9, the rod 21, and one end of the spring 14. This spring is thus wound to rotate the roller in a direction to wind the shade thereon whenever required, and after raising or lowering said shade to the proper extent,
the ball 11, the side 13, and the brake sur face 12, come into play to hold theshade in adjusted position. When raising or lower ing the shade, should it be accidentally released, or should such releasetake place af ter the shade has been properly positloned,
it is prevented from totally winding up, by its rapid movement shifting the ball 11 to locking position.
The device may be constructed easily and inexpensively, yet will be highly etiicient' v having a notch in its lower side provided with a side wall in converging relation with said brake surface, and a ball supported by said brake surface and positioned in said notch for coaction with said wall and said brake surface to hold the roller in adjusted position and to prevent rapid winding' thereof.
2. A hollow spring-wound shade roller having an annular internal brake surface at one end, a non-rotating stub shaft passing centrally into said end of the roller and having a head surrounded'by said annular brake surface, the periphery of said head having a notch provided with a side wall in converging relation with said brake surface, a ball in said notch for coaction with said wall and said brake surface to hold the roller in adjustedposition and to prevent rapid winding thereof, a'coiled spring in said casing connected at one end with said roller and at its other end with said head, a rod extending from said head through said spring, and alateral flange on said rod for retaining said ball in said notch.
3. Ashade roller comprising a tubular shell, end members secured to the ends of said shell, one of said end members having a cylindrical pintle-and the other having a central opening, an annular flange extending inwardly from said last mentioned end member concentric with said opening, a nonrotating pintle passing through said open-- ing'and having ahead surrounded by said flange, the peripheral edge of said head having a notch in its lower side provided with a side wall disposed in converging relation 7 with said flange,,a ballsupported by said flange and disposed in said notch and c0- acting with said wall and said flange to hold the roller in adjusted position, and spring in said shell connected at one end with said head and connected at its otherend with said shell.
4:. A hollow spring-wound curtain roller consisting of circular end members,a metal shell-crimped at its ends around the edges of-said end members, one of said end members carrying a cylindrical pintle and the other having an opening, a non-rotating pintle passing loosely through said opening, a spring in said shell connected atone .end with the latter and at its other end with said non-rotating pintle, and means-for holding the roller in adjusted position. v
5. A shade roller comprising two end members, one of said members carrying a cylindrical pintle and the other having an opening, a single sheet of metal bent into tubular form with its ends secured :to the edges of said end members, the edges of said metal sheet being overlapped and stamped inwardly to :providean internalrib nd to formanchoring means for the upper end of the shade, a non-rotating-pintle passing loosely through the aforesaid opening, a spring in said shell connected at one'end to said non-rotating pintle, a disk in said shell attached to the other end of 'thespring and having a peripheral notch IIGCGilVlIIgISald rib, and means for holding the-roller in adjusted position. 7 V
In testimony whereofl have hereunto set my hand.
