SPECIFICATION forming part of Letters Patent No. 544,371, dated August 13, 1895.
Application filed September 23,1891. Serial No.406,557. (No model.) Patented in Germany April 18, 1889, 110.50.792, and in England January 22, 1890,110. 1,189.
To all whom it may concern.-
Be it known that I, PAUL ORTMANN, of Zittau, in the Kingdom of Saxony, Germany, have invented a new and useful Improvement; in
IVindow-Blinds. (for which I have obtained a patent in England, No. 1,189, dated January 22, 1890, and in Germany, No. 50,792, dated April 18, 1889,) of which the following is a specification.
IO This invention relates to a Window-blind composed of a series of flexible sections that may be either revolved similar to the ordinary slats or may be wound upon a drum.
The invention consists in the various features of improvement more fully pointed out in the claims.
In the accompanying drawings, Figure 1 is a front elevation of my improved window-.
blind; Fig. 2, a top view thereof; Fig. 8, an end view thereof; Fig. 4, a vertical cross-section on line I 11, Fig. 1, with the key It, lowered; Fig. 5, a similar section with the key raised; Fig. 6, a top view of the blind with the flexible slats inclined. Fig. 7 is a front elevation of part of a window-blind, showing a modification of my invention; Fig. 8, a vertical section on line M M, Fig. 7; Fig. 9, a top view of a modification; Fig. 10, across-section on line 0 0, Fig. '7; Fig. 11, a front elevation 0 of a further modification; Fig. 12, a vertical section on line P P, Fig. 11; Fig. 12, an end view of upper part of Fig. 11; Fig. 13, a section similar to Fig. 12 with bar I) disengaged from spring-rod N; Fig. 14., a cross-section on 5 line T T, Fig. 11; Fig. 15, a top view of pin y. With particular. reference to Figs. 1 to 6,
the letters a a represent a series of upright flexible strips secured at their upper and lower ends to short bars I) a respectively, so
.0 as to constitute a set of adjoining flexible slats. The lower bars 0 are pivotally connected to a rod (1. The upper bars I) are of semicircular shape in cross-section and are pivotally connected by pins g to a semicircu- 5 lar roller e, journaled in the window-frame. The parts I) 6 together, when in line, form a complete circular roller. A connecting-rodf, secured to all the bars b, serves to simultaneously incline the slats in the well-known manner by the motion of a single slat. The upper bar of the central slat is marked 11', and to this bar is affixed a pin or arbor h, passing loosely through rod 6. A key 70, depending from the ceiling by a cord n and carrying a sheave i, may be raised or lowered by means of said cord. When lowered, the key engages arbor h, and by pulling on either of a pair of cords Z m, wound around a sheave i, the arbor is turned to revolve bar b. The motion of bar I) is, by rodf, transmitted to the sev- 6o eral slats,so that the same are opened, as in Fig. 6, or closed, as in Fig. 2. The roller 6 carries near one end a sheave 0', around which passes the cord 0. After the key has been raised to release arbor h the roller 6 may be re- 6 5 volved by means of cord 0 to roll up the blind to any desired extent. Of course all the slats should be brought into line, as in Fig. 2, before the blind is rolled up.
In Figs. 7 to 10 there passes through one of 70 the lower bars 0 a shaft N, free to be revolved by hand-wheel R in its bearings t.- The shaft N is connected to a forked arm 11,, that engages slat b, Fig. 9. By revolving shaft N the bars 0 b are likewise revolved. The lat- 7 5 ter, being by the rodf connected to the bars 0 b of all the other slats, cause the blind to be opened to any desired extent.
In Figs. 11 to 15 the revolution of the slats is effected by a divided spring-shaft N. The lower end of this shaft sets in a socket of a crank q, pivoted to the window-frame. The upper spring end of the shaft engages a notch w of bar I) and is guided by a bearing q. When the crank q, and with it the shaft N, is moved in an are around the pivot of the crank, the shaft will impart an opening or closing motion-to the slats by means of the rods f. I
If the blind is to be wound upon the drum 0 e, the upper end of the spring-shaft is first drawn down to become disengaged from notch w, and to thus liberate bar I).
In order to permit the opening and closing of this blind by means of a cord, one of the 5 barse is provided with a downwardly-extending pin or pivot y, that carries a double sheave i, surrounded by cords w. By revolving the sheave the pin y will revolve its bar 0, and this motion will, by rodsf, be transmitted to the entire series of slats.
Vhat I claim is- 1. The combination in a window blind of flexible slats pivoted at the top and bottom with means for rolling them up in the direction of their longer axes, and with means for simultaneously vibrating them on their pivots, substantially as specified.
2. The combination of a divided flexible blind, with bars 12, secured thereto, a roller 6, to which the bars are pivoted and rod f, connecting the blind sections, substantially as specified.
3. The combination of a divided flexible
