CURTAIN FOR LAMP SHADES 0R DOMES.
Patented Dec. 6. 1921.
Application filed April 28, 1921. Serial No. 465,085.
To all whomit may concern:
Beit .known that I, HENRY AUGUST F.
KUnnn, a citizen of the United States, and a resident of the city of New Yorkyborough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Curtain for Lamp Shades or Domes, of which the following is a full, clear, and exact description.
The invention relates to lighting fixtures, and its object. is to provide a new and mm proved curtain more especially designed for use on lamp shades or domes and arranged to permit the user of the lamp to readily shade the eyes against the direct rays of light. emanating from the burning lamp.
Another object is to provide a curtain which is normally in inactive, "out ofsight position, and can be readily drawn into actlve position by the user of the lamp.
Another object is to permit of conveniently and quickly attaching the curtain to the lamp shade or dome.
lVith these and other objects in view, the invention consists of certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings forming. a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure l is a plan view of the improved curtain as applied to a dome, the latter being shown in section;
Fig. 2 is an enlarged sectional side elevation of the same on the line 2-2 of Fig. 1;
Fig. 3 is an enlarged sectional side elevation of the spring end of the curtain roller;
Fig. l is an end elevation of the improved curtain with the supporting frame shown in section; and
Fig. 5 is a perspective view of a modified form of curtain as. applied to the dome shown in section To the inner face of the lower portion of a lamp shade or dome 10 is secured a frame 11, preferably made of spring wire bent into hexagonal or other polygonal shape with the corners 12 rounded off and bearing against the inner face of the dome by the resiliency of the spring frame. On any one or on two or more of the sides 13 of the frame 11 are hooked brackets 15, 16 provided at their lower ends with bearings 17 and 18 in which are journaled the ends of a spring controlled roller 20 on which winds a curtain 21 of silk or other suitable flexible material. The roller 20 at the bearing 18 of the bracket 16 is made hollow to receive a spring 25 fastened at one end to the roller and at the other end to the bearing 18, and this spring is wound up on pulling the curtain 21 downward and thereby rotating the roller 20. When the curtain 21 is drawn downward into open position, as shown in Fig. 2,then
it extends below the dome 10 and thus shades the eyes of the user of the lamp against the direct rays of the light emanating from the lamp of which the dome 10 forms a part.
In order to hold the curtain 21 in extended position use is made of two spring pawls 26 and 27 forming part of the bearing 18 and adapted to engage grooves 28, 29 formed lengthwise 011 the hollow end of the roller 20, as plainly shown in Fig. 3. It is understood that when the curtain 21 is drawn down and the roller 20 is thereby rotated then the spring 25 is placed under compression and the roller is locked against aocidental return movement by the pawls 26, 27 engaging the shallow grooves 28 and 29. When it is desired to return the curtain '21 to inactive, wound-up position then a slight pull on the curtain turns the roller 20 sufficiently to disengage the pawls 26, 27 from the shallow grooves 28. 29, and then on the operator quickly releasing the curtain 21 the spring 25 turns the roller 20 with a view to wind up the curtain 21.
It will be noticed that the frame 11 can be readily sprung into position on the inner face of the lower portion of the dome or lamp shade l0, and a pair of brackets 15, 16 with a roller 20 journaled thereon can be readily hooked onto any one of the sides 13 of this frame to locate the curtain 21 in the proper position to shade the eyes of the user of the lamp. It will also be noticed that when the curtain 21 is in wound-up position it is completely concealed within the dome 10 together with the supporting frame 11 and hence the attachment does not affectthe appearance of the dome 10.
Instead of using the supporting frame 11, use may be made of shade roller brackets 40 mounted or otherwise attached to the inner face of the lower portion of the dome 10, as indicated in Fig. 5. It is understood that the brackets 40 support the roller 11 on which winds the curtain 4E2.
Having thus described my invention, I claim as new and desire to secure by Letters Patent;
1. A curtain for lamp shades 0r domes, comprising a frame made of apiece of spring wire bent into polygonal shape, the corners of the frame frietionally engaging comprising a frame made of a piece of spring wire bent into polygonal shape, the corners of the frame frictionally engaging the inner face of a lamp shade or dome. brackets suspended from the sides off the said frame and arranged in pairs, a springcontrolled shade roller jonrnaled in the said pairs of brackets and having an exterior groove at one end. a spring pawl adapted to engage the said groove and mounted on the adjacent bracket, and a curtain o'l flexible material Winding on the said roller.
