.To @ZZ whom it may concern.- Y
Beit known that I, MARTIN GEORG MITTER, manufacturer, of the city of Berlin, Prussia, Germany, have invented certain new and useful Improvements in Window Blinds or Shades;
and I do hereby declare that the following is a full, clear, and exact description thereof.
The object of myinvention is to produce an adjustable blind or shade for windows that can be drawn up like an ordinary blind, and lowered from the top and raised from the bottom to any extent without entirely removing it from the window.
Referring to the drawings, Figure I is a side View of my improved window-blind and adjustable attachment. Fig. II is a side view of the same. Fig. III is a plan sectional view of the same. Fig. IVis an enlarged side View of the roller and attachment. Fig.Vis a detached sectional view of the roller. .Fig.VI is a side elevation of a modification. Fig.VII is a front elevation of the modification of Fig. VI. Fig.VIII is a plan View of Fig.VII. Fig. IX is a detached enlarged side view of Fig. VII. Fig. X is a detached enlarged side and end view of Fig. VII.
a a are two ratchet bars placed one on each side of a window or opening.
C C are two rollers, provided with cog-wheels b b at their outer extremities, corresponding with the teeth of the ratchet-bars c a. These rollers are suspended on the movable frame lc, which slides in grooves cut in the window-casing. (See Fig. III.) These rollers are` made double, the object of which is to enable the said rollers to fit any size window or opening. In some cases the rollers are provided withaspiral spring, c, to give elasticity to the movements of said rollers. Over these rollers is placed the blind or shade, which is wound and unwound from one roller to the other. The two rollers, with their carriers, are moved up and down bythe cord which passes over wheel h, and is connected to winding-roller g. Although the roller C can move with roller Owhen the said roller Gis moved upward, yet there are times when it is necessary to roll the shade up from the lower roller. In order` to accomplish this I use the cordA D, attached at one end to the sliding frame la, and passing over the pulley 13, att-ached to the frame 7c, secured to the upper roller.
The operation of my invention is as follows: The window blind or shade is rst attached to the rollers C aud C. If the blind or shade is first required to be entirely rolled up, it is wound around roller C. If it is required to be rolled down, it is wound around roller C. Should the blind or shade be required to cover but only half of the window, the roller C is lowered by cord I. As the rdller C is lowered the cog-wheels b brotate the same by coming in contact with teeth of the ratchet-bars c a. lf the lower roller is likewise required to be rolled up to admit light through the window under the blind or shade, all that has to be doneis to pull up the cord I. As the rollermovcs itlikewise rotates the same, owing to the cog-wheel comingin contact with the teeth of the ratchetbars a a.
In the modification shown in FigsVI, VII, and VIII, .ris a guide-rail, made of wood or metal, placed on both sides of the racks. The part m at the end of the rollers is smaller in diameter than the roller itself. The parts m extend beyond the cog-wheel b, Figs; VI and VIII, and are placed in the guide-rail x, for guiding the same in ascending and descending. By this means the blind can be xed closer to the racks and allow the window to move up and down. Again, by these guide-rails the blind receives an easier motion,as the friction of the bearing in sliding is avoided,which is an advantage, because the blind is exposed tothe influence of the weather.' Furthermore, in Figs. VI and VIII a contrivance is presented which has for its object the tting of the blind when arranged out of doors in rough and stormy weather, and likewise prevents the falling of the rollers. This c ontrivance consists of a plate, B, to which the cords I and II are fastened. The plate B has a slit, o, in which the narrower part of the'roller m of the upper and lower roller is placed, respectively, so that it can revolve. The plate B has over the periphery of the cog-wheels b a peg, n, which, when desirable, enters between two teeth of the cog-wheels lying under it. W'hen this contrivance is put in action, the rods I II are loosened, respectively. The plate B will then, by its own weight, fall so far that the peg u comes in close contact with the cog-wheel, and in this way holds fast the roller. By drawing the cord the plate B moves on peg m in slit o. rThis movement frees the peg n from the action ofthe cog-wheel.
The above-described device for adjusting blinds or shades has these advantages: It enables the blind to be drawn up like an ordinary blind. It also enables the blind to be lowered from the top or raised from the bottoni without necessitating` the removal of the blind entirely from the window.
Having thus described my invention, I dcsi re to claim- In a window blind or shade, the rollers (l C', provided with cog-wheels I) Il at cach endy and made in two parts, which are forced outward by spiral springs c, the roller C being connected to the roller C by cord D, fastened at one end to the roller C', and passing over pulleyfzl on franiek, and both these rollers as connected being)r moved np and down by a cord, I, passing over wheel la, attached to the windowframe and fastened to theWinding-roller g, and rotated by the ratchetebars a af, fastened onto the sides of the windowframc, all arranged substantially as and foll the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 3d day ofMay, 1886.
