ISHMAEL F. HURLIBUT, OF SAN FRANCISCO, CALIFORNIA.
CURVED SHADE-ROLLER AND CURTAIN-ROD.
To all whom it may concern:
Be it known that I, ISHMAEL F. HURLBUT, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented a new and useful Improvement in Curved Shadedtollers and Curtain-Rods, of which the following is a specification.
My invention relates to curved shade rollers and curtain rods wherein parallel rods are suitably supported by means of end brackets and the inner rod, or that rod nearest the window, is provided with a plurality of rotatable telescoping sections connected to each other at one point only, and are supported upon the said inner rod, and wherein a coiled spring is adapted to rotate the tele' scoping sections for the purpose of rolling or unrolling the shade upon the roller. I also employ novel means on the same brackets for the support of a curved curtain rod upon which may be hung the lace or other curtains which are usually provided inside of the shade, and the objects of my invention are, first, to provide a curved shade roller which is adapted to hold a shade suspended in a curve parallel with the curved window near which it is attached, second, to provide a flexible tube which is adapted to rotate upon and readily conform to the curve of a stationary curved supporting rod, third, to provide means for readily rewinding a shade upon the roller, fourth, to provide a simple and substantial connection between each section of the flexible tube, novel and practical means for the support of a curved curtain rod so that the said curtain rod shall be maintained in a horizontal plane.
For a full and clear comprehension of my invention, reference should be had to the drawings forming a part of this specification, wherein like numerals of reference designate similar parts throughout the said specification and drawings and in which- Figure 1 is a broken plan view of the curved shade roller disclosing the telescoping sections rotatably mounted upon the stationary supporting rod. F ig. 2 is a broken detailed view of one end of the flexible tube, disclosing the manner in which the rotating spring is wound upon the rod and connected at one end to the end section. Fig. 3 is an end view, on an enlarged scale, of Fig. 2, disclosing the manner in which the pawls are secured to the end section Specification of Letters Patent.

and engage the stationary supporting rod.
Fig. 4: is an end View, on an enlarged scale, of the bracket and the flexible tube, also showing the manner in which the curved curtain rod is secured to the end of the bracket. Fig. 5 is a detailed broken view of one end of the curtain rod disclosing the manner in which the end of the bracket engages the end of the said curtain rod.
My invention consists substantially of suitable supporting brackets 1 having slots 2 adapted to engage and hold against rotation the ends of the curved inner parallel rod 3. Hollow telescoping sections 5 are pivotally secured to each other at one point only as at 6 and are adapted to rotate around the stationary rods 3. Each of the end sections 5 are provided with the circular, flanged end plate 7 to which are pivotally secured the pawls 8 adapted to engage the squared portions 3 of the rod 3. A disk 10 is rigidly secured to the center of the rod 3 and to this disk 10 is secured the center of a coil spring 9, the opposite ends of the said spring9 being rigidly secured to the end plates 7. The brackets 1 are provided with offset extensions 12 at the outer ends thereof, the said extensions 12 being adapted to engage, support and held against rotation the curved parallel curtain rod 1 1 by means of the slot 15 which is provided in the lower surface of each end of the said rod 14. (See Fig. 5 of the drawings.) In this manner the curved curtain rod is supported and held against rotation for the reason that the greater part of the curved rod is inside of an imaginary line drawn between the extensions 12 of both brackets. As the tendency of the curved rod would be to rotate until the center thereof rested at a point below the points of support, the edge of the slot 15 which is below the extension 19. would tend to move upward. As this tendency of the lower edge of the slot to move upward is checked by the extension 12, it is apparent that the curved curtain rod 14E will be held so that the curve thereof is always in a horizontal plane.
The operation of the curtain roller is as follows: The inner parallel rod 3 is held against rotation by means of the slots 2 in the brackets 1 and acts as a support to the rotatable telescoping sections 5 thereon. The shade is secured in any suitable manner to the outer surfaces of the telescoping sections 5. By pulling downwardly, the shade will cause the telescoping sections 5 to rotate against the tension of the spring 9 which is secured to the said sections 5 and to the inner parallel rod 3. Then the shade is released, the tension of the spring 9 will cause the sections 5 to rotate in the opposite direction and thereby wind up the shade. As the combined sections 5 rotate they readily conform to the curvature of the inner parallel rod 3 for the reason that each section 5 is pivotally seclured to the succeeding section at one point on y.
I am aware that telescoping sections have been heretofore employed wherein the said sections were pivotally connected to each other on diametrically opposed points in their adjacent peripheries and the combined sections inclosed by means of a flexible covering. But the flexibility of such an arrangement has been proved in practice to be insufficient for the reason that two adj oining sections could only turn on one axis and the consequent friction of the flexible covering was also adapted to resist a free conformity to the curvature of the supporting rod. In my device I have provided connection of the sections at one point only so as to insure an easy and free movement between the sections. In this manner my device is adapted to readily and freely adapt itself to the curvature of the inner sup-porting rod in any position.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A curved shade roller and curtain rod comprising curved parallel rods; means for supporting the parallel rods above a window casement; telescoping sections rotatably mounted upon the inner parallel curved rod and connected to each other at one point in their adjacent peripheries; and a coil spring secured to the inner parallel rod and adapted to rotate the telescoping sections in one direction.
2. A curved shade roller and curtain rod comprising curved parallel rods; suitable brackets adapted to engage the ends of the parallel rods and to support the same .above a window casing; telescoping sections rotatably mounted upon the inner parallel curved rod and connected to each other at one point in their adjacent peripheries; a coil spring secured at both ends to the end telescoping sections, the center of the said spring being secured to the inner parallel rod; and means for retaining the telescoping sections against rotation.
3. In a curved shade roller and curtain rod, the combination of suitable brackets, each bracket having a slot in the upper edge and an oifset extension on the outer end thereof; an inner curved rod adapted to be rigidly held within the slots of the brackets and having a squared portion near the outer ends thereofand within the brackets; an outer curved rod having slots in the under surfaces at the outer ends thereof said slots being engaged by the offset extensions of the brackets; telescoping sections rotatably mounted upon the inner curved rod and pivotally connected to each other at one point in their adjacent peripheries; a disk set within the outer end of each outer section; and pawls pivotally secured to each disk and adapted to engage the squared portions of the inner rod and prevent the rotation of the telescoping sections when the said sections are rotated slowly.
In witness whereof I hereunto set my signature in the presence of two subscribing witnesses.
