R. SATO WINDOW SHADE Filed Jan. 6, 1922 J0 JJ 16\ 7% w '17 21 17 21 3 Patented May 26, 1925.
UNITED STATES PATENT "WINDOW SHADE.
Application filed January 6, 1922. sefiarmfi5az'4o3.
To all whom it 'may concern:
"Be it known that I, RY JrSa'ro, a citizen of Japan, residing-at New York city, in the eountyof New'Yorl: and StatebfNew York, have invented new and useful Improvements ly efficient for the purpose for-whiclrit is designed.
Another object is to producea'device of this nature having special reinforcement" for preventing stretching and distort on :at the points of greater strain.
IVith these and other objects in view, the invention resides in'certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing', in which Figure 1 is a view of a window frame provided with my improvement and arranged to obstruct a portion of the light from the top of the window.
Figure 2 is a similar view with the obstruction at the bottom.
Figure 3 is a longitudinal section of one of the curtain rods.
Figure l is an extended view of the curtain.
Figure 5 is an enlarged detail vertical sectional view on the line 5-5 of Figure 1.
Like characters of reference refer to like parts in all views.
Referring to the drawing in detail, it will be noted that the curtain proper which is indicated at 10 is three times the length of the ordinary window curtain necessary for the desired length of window aperture. The third of the curtain at each end is solid as is the ordinary curtain and the central third is apertured as at 1 1 forming side strips 12, the material from the aperture 11 being folded back so as to finish and reinforce the edges of the aperture. At the top and bottom of the aperture 11 springy strips 13 preferably of" tin 1r sheet steel" are-sewed into the structu-re so as toprevent the crushing together of the eurtain andi to 'cause it to roll in rp'i oper ly at*'each end. The' window frame is i'shown at 144 having the usual aperture 15 toregisterwith the aperture 11 inthe curtain.
The brackets are showmat 16 and a re preferably formed 'of spring'steel which tend constantly: to press toward the 1 center. As two rollers are used in the present construction, twopai-rs of brackets aresho'wnfiarranged above and 3 below i the .aperture- 5 '15,
respe'ctively. The roller proper'isnuinbered 17 and 1S1 provided: with the usual bracket engaging'studs 1S. lVIounted-loosely on:'a
reduced portion at'oneend of the 'rol ler is a pulley member 19 having ratchet teeth. 20 formed oir-i'ts inner face and adapted toengage with ratchet teeth-"21 on the-adjacent "portion of the-ro'ller 17. 'Dhe'tetath are so set that when the pulley isturned' tm\viard the curtain on the respective roller, the teeth on the pulley of the other roller will ratchet idly so as to permit of the necessary advance in movement due to the difference in size of the rolls as the curtain is Wound from one to another. A cord or belt 22 connects the two pulleys so that by turning the belt in one direction one pulley will be caused to roll the curtain upwardly while in turning the belt in the opposite direction the other pulley will be caused to roll the curtain in the opposite direction.
IVhile I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.
hat is claimed as new is 1. A device of the class prising a pair of curtain rollers one adapted to be arranged in spaced relation to the other upon a window frame, a curtain equal to three times the length of the window frame having its opposite ends secured to said rollers, and an aperture in said curtain equal to the length of the window opening in said frame. v
2. A device of the class described comprising a pair of curtain rollers one adapted to be arranged in spaced relation to the other described com upon a window frame, a curtain equalto three times the length of the window frame having its opposite ends secured to said rollan opening formed centrally therein equal,
to one-third its length and having its ends secured to saidrollers, a manipulating means connecting said rollers and common to both for moving said curtain in opposite directions.
4. A device of the class described comprising a pairof curtain rollers, a curtain equal to three times the length'of a window .frame on which the same is to be used and having an opening therein equal to onethird its length and having its ends secured to I said rollers, strips of springy material inserted in said curtain at opposite ends of said opening, a manipulating means connecting said rollers and common to both for moving said curtain in opposite directions.
5. A device of the class described comprising a pair of rollers, a curtain provided with an aperture and havin its ends secured to said rollers, strips of springy material inserted in said curtain at opposite ends of said aperture, ratchet teeth formed on one end of each of said rollers, pulleys mounted adjacent said rollers and having ratchet teeth for co-action with the teeth on said rollers respectively the ratchet teeth of one roller and its mating pulley being opposite those of the other roller and pulley,- andxa belt connecting said pulleys for effecting movement of said curtain in either direction.
6. In a device of-the class described, the combination with a window, 'a pair of rollers, one of said rollers arranged at the top of said window and the other at the bottom thereof, a curtain equal to three times the length of said window, provided centrally thereof with an aperture and equalto, onethird the length of said curtain, and means formovingsaid curtain in opposite directions for bringing said aperture into and out registration with said window'whereby theamount of light through said window may be regulated.
In testimony whereof I haveaflixed my signature. I Y
