Application filed March 22, 1886. Serial No. 196,104. (No model.)

To all whom it may concern:

Be it known that I, James Naylor, of Providence, in the county of Providence and State of Rhode Island, have invented a new 5 and Improved Slat-Adj uster for WindowBlinds, of which the following is a full, clear, and exact description.

The object of my invention is to provide a practical and convenient device for adjusting io the slats to window-blinds to hold them at any desired angle when the blinds are closed; and the invention consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

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

Figure 1 is an inside sectional view of the 20 lower part of a window casing and blinds, showing my invention applied to the blinds, the right-hand screw or worm shaft being removed to show the lifting device and the slot in the casing to receive it. Fig. 2 is a sec25 tional elevation taken on the line xxof Fig. 1, and Fig. 3 is a plan view of one of the lifting devices removed.

A represents the window-sill, and B the inside portion of the sill or a casing closed by 30 the top piece or _zcover, C. In the casing B and cover 0 are journaled the two screws or worm-shafts D, one for each blind E. The worms D are each provided at their upper ends, above the cover C, with a knob, c, by which they may be conveniently turned to the 35 right or left, and on each worm is placed a lifting device, F, so that by turning the worms these may be raised or lowered for raising or lowering the slat-rods G, to which the slats g of the blinds are attached. The slat-rods G 40 are kept in position in line with the lifters F by the sleeves H, secured to the window-blind. The lifters in this instance are each formed with an upright portion, / top plate, /', and lower horizontal arm,/², which is flattened 45 and formed with the threaded aperture /³, through which the screw or worm shaft passes, and the lifters in this instance are held in position for direct vertical movement by being placed in narrow cavities J, formed in the 50 window-sill. The lower ends of the shaft D are journaled upon step-blocks K, as shown clearly in the drawings.
