This invention relates to a new and useful device in the nature of a curtain roller adapted for the purpose of providing a means of extending a curtain in combination with a means of holding the said curtain in a closed or rolled position when not in use.

The object of the invention is to provide a curtain roller of novel construction and arrangement of parts hereinafter more fully described, claimed, and illustrated in the accompanying drawing.

Fig. 1 is a front elevational view of my improved curtain roller showing the curtain partially extended.

Fig. 2 is a longitudinal central sectional View thereof.

F ig. 3 is a transverse sectional view thereof.

Fig. 4 is a similar view to that shown in Fig. 2, illustrating a further development of my improved device.

As here embodied my improved curtain roller comprises a tubular member 10, of any desired length, depending upon the width of the window, door, or the like, to which same is attached. The tubular member 10 is provided with closed ends 11 and 12, secured thereto. The handle member 13 is secured te one of the said ends, and has preferably formed therein an aperture 14 so as to provide a ready and convenient means of handling my improved device.

The rod 15 is secured at its extremities to the central portion of the ends 11 and 12 and extends longitudinally of the tubular member 10. The spiral spring 16 is freely wound on the rod 15 and is secured at one extremity as at 1 8 to the rod 15 at one end near one extremity thereof, and is secured as at 19 to the end member 20.

The end members 20 and 21 are rotatively mounted on the rod 15 adjacent to the extremities thereof, and are secured to the extremities to the inner elongated hollow member 22, preferably of triangular cross- 5 section, having three surfaces somewhat con- Vex extending longitudinallj,7 of the rod The curtain 23 is secured at one extremityY to the inner elongated hollow member and normally wound thereon. The curtain 23 may be of any desired plan or ornamental design, and made of any desired suitable material, such as ordinarily used for curtains, draperies, hangings, and the like. The cur= tain 23 is extended through an elongated opening 24, formed longitudinally in the low- 55 er portion of the tubular member 10 and has secured at its extended or free extremity at the center thereof an eyelet 25, or a plurality' of apertures 26 may be formed in the tree extremity of the curtain 24 adapted to 6C ene'age over a hook, or hooks secured tothe lower portion of the window sill or door trame, as a. means of holding the curtain 24 in an extended or in use position. Rollers 27 and 28, are rotatively mounted on the 65 rods 29 and 30, respectively, secured to the above mentioned ends 11 and 12, and extended longitudinally of the tubular member 10 and located adjacent to the said elongated opening The above described constru'c- 70 tion is such as will permit the said curtain when extended to engage the said rollers 27 and 28 so as to prevent injury to the said curtain. The plate member 31 is secured as at 32, by rivets, screws, bolts, or the like, to the rear portion of the tubular member l0 and extends longitudinally thereof. The plate member 31 is adapted to slidably engage in the bracket 32, which is provided with up ier and lower extended elements 33 80 and 34, havi g inwardly formed or bent extremities, so as to provide longitudinal recesses adapted to receive the upper and low-l er edges et' the said plate member. The brach et is secured to the upper portion of the win-dow or door trame so as to removably hold my improved curtain roller in the desired position. y

lt is obvious from the foregoing description that the said spring 16 will normally 90 hold the curtain 24 in a wound position.

VYvJhen the shade is unroll'ed and attached at its tree end to the window sill or other means, there are two factors which determine the tension applied thereon. `One factor' is' the extent to which the shade is unwound and the spring tensioned and the other is the position or" the spherical-triangular shapedv roller in cross-section. It should be under'- stood that when the roller is in the position shown in Fig. 3 that portion of the shade about to be rewound is engaged by one of the angular` portions thereof and the force applied on the shade by the roller is less than when the shade portion about to be rewound is engaged by the convex section of the roller between the angles thereof. This relation will be understood by comparing the distance from the center of the roller to the convex sides and the distance from the center of the roller to the corners or edges thereof.

When it is necessary to extend the shade a considerable distance it may be found de sirable to secure the bottom or ree end of the shade in such a position as to have one of the edges of the roller apply the force of the spring. This arrangement will protect the material comprising the shade from excessive tension over a long period of time. When it is only necessary to extend the shade a slight amount it may be desirable to stop the roller in such a position as to have the force of the spring applied on the shade by one of the convexed sides of the roller so as to have sulicient tension in the shade to retain it smooth and unwrinlrled. Obviously the positioning of the roller can be determined by the pull required by the shade in adjusting it.

In Fig. 4 of the accompanying drawing I have shown the spring secured at one extremity thereof, to the rod 35 secured at one extremity to the central portion of the end 11, slidably engaging in the tubular member 36, secured at one extremity to the end 12. The tubular member 37 similar to the above mentioned elongated hollow member 22, is secured at one extremity to the end 21, and is provided with an extended portion 38, somewhat smaller, adapted to slidably engage in the elongated hollow member 39, similar to the above mentioned elongated hollow member 22 secured to the end 20.

The tubular member 40, similar to the above mentioned tubular member 10 is secured to the closed end 11, and is adapted to slidably vengage in the tubular member 41, similar to the said tubular member 10, and is secured to the closed end 12. Clips 42 are secured at one extremity as at 43, to the free extremity of the tubular member 40, and are provided with inwardly extended element 44 adapted to engage in apertures 45, formed in the tubular member 44. The clips 42 are preferably of spring steel, tempered so as to be normally urged inwardly and engage in the said apertures 45. The above described construction is such as will permit my improved curtain roller to be extended, as may be desired, to accommodate doors and windows of various widths. It should be understood that the said curtain 24 will be smoothly wound on the said tubular members 37 and 39 inasmuch as the edges of the said curtain engage in the. portions of the tubular members 37 and 39 which are of the same or identical size.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. In a device of the class described, a casing comprising a pair of telescoping sections, a tubular member secured to one end of one of said telescoping sections, a rod secured to the end 0I the other telescopng sections and extending into said tubular member, a hollow roller substantially in cross section and comprising telescoping sections journaled on said rod and tubular member, a spring disposed around said rod and tubular member secured at one end to said hollow roller and at its other end to Said rod adapted to be varied in tension by extension of the telescoping section of said casing and roller, and a shade wound on said roller attached thereto at one end and disposed outwardly through a slot in said casing adapted to be urged inwardly with a force of one intensity by said spring when the force of said spring is applied by the edges of said roller and to be urged inwardly by the same spring with a greater force when the force of said spring is applied by a side of said roller.

2. In a curtain roller of the class described, an elongated hollow member rotatively mounted for holding a wound curtain and being of spherical-triangular cross-section, and a spring within the member acting to mainain the curtain wound on the hollow mem- 3. In a curtain roller of the class described, an elongated hollow member of s heriealtriangular cross-section and provi ed with end members, a rod for rotatively supporting the hollow member and extending thru the end members, and a spring coaxial on the rod and having one end secured on the rod and the other on one of said end members for acting to maintain a curtain wound on the hollow member.

I n testimony whereof I have afixed my signature.

GASPAR GARCIA.
