INSIDE BLIND.

SPECIFICATION forming part of Letters Patent No. 357,888, dated February 15, 1887.

Application filed Mart-h 14, 1885. Renewed Janiiary 11, 1987. Serial No. 224,057. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN \V. ANDERSON, a citizen of the United States, and a resident of St. Louis, in the county of St. Louis and State of Missourhhaveinvented certain new and useful Improvements in Inside Blinds for Windows; and Ido hereby declare that the following isa full, clear, and exact description of the invention, which will enable others skilled in the art to whichit appcrtains to make and use the same, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure 1 is afront view of my improved inside blind, showing the same applied to awindow in position for operation. Fig. 2 is a side View of the same, with dotted lines showing the slats in a raised position; and Figs. 3 and 4 are perspective views, on a largerscale, of the sockets or clamps used at the two ends of the slats.

The same letters refer to'the same parts in all the figures.

My invention has relation to that class of Window-blinds which are composed of a number of slats connected so as to havetheir edges overlapping each other, having cords for drawing them up to rest with their fiat sides packed close upon each other, and having cords or chains attached near their edges, by means of which the inclination of the slats may be regulated; andit consistsin theimproved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the drawings hereto annexed, A designates the window-frame to which my improved blind has been applied.

B designates the blind, which is composed of a series of slats, C G, the ends of which are pro vided with metallic clamps or sockets. (Des ignated, respectively, byD and D Said sockets are provided with staples E E by which they are pivoted or connected to the links F of the chains G, whereby the slats are connected so as to form the blind. When thelatter is extended, the slats will overlap each other, as will be seen in Fig. 2 of the drawings.

The upper ends of the connecting-chains are attached within a box-like cornice or casing, H, which is secured under the top of the windowframe, and which serves to receive and accommodate the blind when the latter is folded.

I is a cord passing around the blind under the bottom slat, as shown, and the ends of which pass over a pair of parallel pulleys, J J, arranged in the cornice-box, respectively in front and inrear of the blind. The ends of the cord pass together through a screw-eye or guide, K, and over a pulley, L, at one end of the cornice'box, whence it depends so as to be readily reached and manipulated for the purpose of raising or lowering the blind, as the case may require. The sockets D at one end of the blind are, in addition to the staples Eflprovided with perforated lugs or eyes M at their lower corners, whereby they are attached to a cord, N, running over a pulley, O, at one end of the cornice box, whence it hangs down within easy reach of the operator, who, by pulling the said cord, will lift the lower free edges of the slats, which are thus raised to an approximately horizontal position,s0 as to offer no hinderance to ventilation.

The operation of this invention will bereadily understood from the foregoing description, taken in connection with the drawings hereto annexed. Vfhen the depending ends of the cord 1 are released, the blind will be unfolded by its own weight. By pulling the said cord the blind may be partially or entirely folded, and it may be thus retained by simply making the cord I fast to some suitable hook attached to the window frame or sill. By pulling'the cordN the slats of the blind, or as many of them as are at the time unfolded, maybe raised toward a horizontal position, as shown in Fig. 2, for the purpose of ventilation. The cordN may also be made fast in any suitable manner.

It will be seen that the metallic caps at the ends of the slats will serve as secure points of attachment for the connecting-chains and for the adjustingcord, avoiding the necessity of securing cords or staples to the slats, which are preferably strips of wood, which would easily split or break during use.

I am aware that slat-blinds have been made having chains connecting the slats, so as to have their edges overlapping each other, and having cords or chains connected to their free edges for the purpose of adjusting the angle of inclination of the slats, andI do not wish to make any broad claims for such constructions;
