JOHN CLARK, OF WILLIAMSBURG, NEW YORK.
MODE OF OPERATING WINDOW-BLINDS.
Specification of Letters Patent No. 22,625, dated January 18, 1859.
To all whom it may concern:
Be it known that I, JoHN CLARK, of VVilliamsburg, in the county of Kings and State of New York, have invented a new and useful Improvement in VVindow-Blinds; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which i Figure 1, is a side or face view of a window blind having one of its stiles bisected or portion of it removed in order to show my invention. Fig. 2, is a section of the stile above referred to taken in the line 00, 00, Fig. 1.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to an improved mode of operating the slats of the blind as hereinafter fully shown and described, whereby many advantages are obtained over the old modes or over all those that have come under my observation, to wit, the blind having a far neater appearance, more durable, less liable to get out of repair and the slats more readily adjusted, the cost of construction not being materially if at all enhanced.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A, B, Fig. 1, represent the two stiles of a window blind, a, being the upper and b, the lower cross rail.
0, are the slats of the blind. The slats are constructed of the usual form, provided with tenons 0, c, at their ends, the tenons being fitted in the stiles A B, and allowed to turn freely therein.
The tenons c, of the slats G, are fitted in the stile B, and each tenon 0, has a spiral toothed flanch cl, placed on it, or an ordinary pinion will answer the same purpose.
In both drawings spiral toothed fianches are shown instead of pinions. The form of these fianches are clearly shown in Fig. 1.
In the stile B, a rack bar D, is fitted or placed longitudinally and allowed to slide freely up and down therein. Into this rack bar the fianches (Z, gear as shown plainly in both figures. The lower part of the rack bar has teeth 6, formed on it at one side and into the teeth 6, a pinion f, gears. The pinion f, is placed on a spindle or arbor g, which passes into the lower part of the stile B, and has a knob h, on its outer end, the inner end of the arbor g, being stepped or having its bearing at 2', as shown in Fig. 2, the knob it, being at the inner side of the blind. At the inner side of the blind a projection j, is attached through which the arbor g, passes, and 7c, is a pin which is attached by a chain Z, to the lower part of the blind, said pin forming a lock to the arbor or spindle, preventing it from turning by passing it, the pin, when desired through the projection j, into the arbor or spindle, a hole m, being made in the arbor to receive the pin.
From the above description it will be seen that by turning the knob h, the rack bar D, will be actuated and the slats C, opened and closed or turned as desired. The friction attending the movement of the working parts is sufficient to prevent any casual movement of the slats and the slats may be secured in a closed state so that they cannot be turned at the outer side of the blind, by inserting the pin is, in the spindle or arbor g.
I would remark that the arbor 9, may project through the knob 71-, and have a square 2', formed on it to receive a key which may be passed through the lower rail of the window sash and thereby permit the slats C, to be adjusted without raising the window sash. I would also remark that when the flanches d, are used or employed the rack bar D, is provided with a curved sunken gear j, to receive the toothed fianches cl. I/Vhen however pinions are used a simple straight rack is attached to the bar D.
By the above invention the usual slat rod is dispensed with, a clear unobstructed space being obtained in front of the slats. The slats may be adjusted with facility far more so than by the slat rod or all other modes of adjustment with which I am acquainted. The blind by my improvement is also rendered more durable, the slats are not liable to be split or injured by being turned as is the case where the slat rod is employed. The blind as a whole has a far neater appearance than usual.
Having thus described my invention What S. COLT.
