SPECIFICATION forming part of Letters Patent No. 440,238, dated November 11, 1890.

Application filed November 26, 1889. Serial No. 331,669. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN P. CLARK, J r., of Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Window-Blinds, of which the following is a full, clear, and exact description.

My invention relates to improvements in inside blinds for windows; and it consists in the construction and combination of parts as hereinafter described and claimed.

The objects of my invention are to provide a cheap, convenient, and substantial inside blind for a window.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an elevation of the inside of a window having the improved blind. Fig. 2 is asectional side elevation of the window-frame and the sashes, taken on the line 2 2 in Fig. 1, the blind being shown as open; and Fig. 3 is a sectional plan view of one of the blinds and the window-frame to which it is attached.

A A are the stiles of a window frame or casement, A the cap-plate therefor, and A \Vithin the frame the sashes a a" the sub-sill. are adapted to slide in the usual way, or they may be hinged together and adapted to swing inwardly, as I do not wish to limit the application of the blinds to any particular type of window.

Upon the stiles A inner blinds B are secured by hinges, said blinds being preferably constructed of narrow strips of board 0; or lathing material may be utilized in their man ufacture, if desired. Said strips are of sufficient length to extend from the cap-plate to the sub-sill of the window-frame, and are hinged together at b, so as to adapt them to fold properly together when the blind is opened.

Any suitable number of the vertical strips 0 are employed, and they are longitudinally grooved, as shown in Figs. 1 and 3, whereby a corrugated surface is produced on each side of the blind strips, the grooves on one side alternating with those of the opposite side, so as to produce a serpentine effect in cross-section, as shown in Fig. 3. This plan of construction lightens the material, ornaments the blind strips, and also serves to prevent them from warping or twisting out of correct shape.

There may be one or two blinds provided for a window. Two of equal width are preferably employed and meet at the center of the window when closed.

To afford a substantial connection of the blinds to the stiles of a window, they are each connected to vertical bars d by hinges d, and the bars are secured to the window-stiles by hinges 6, attached to the bars and stiles at right angles to the hinges 02, said hinges being secured to the flat sides of the adjacent blind-strips 0, whereby a more substantial connection is provided than would be effected if they were put upon the edges of the same.

By connecting the blinds B to the bars (1 and connecting the bars to the stiles A of the window-frame greater strength is afforded, a neat finish is produced, and the blinds are adapted to fold fiat against the wall of the apartment when opened, as shown in Fig. 3.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with a window-frame and sash therein, of a vertically-slatted blind com-
