Ntra STATES Arena" OBEN WILLIAMS, OF GOUVERNEUR, NEW YORK.

Specification forming part of Letters Patent No. LllQQS, dated pri 1564.

To all whom it may concern.'

Be it known that I, OBEN WILLIAMS, of Gouverneur, in the county of St. Lawrence and State of New York, have invented a new and useful device for opening and closing window-blinds, and also for opening and closing the slats thereof; and Ido hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is an inner side or face view of a window-blind having my invention applied to it; Fig. 2, a vertical section of the same, taken in the line :v Fig. l; Fig. 3, a horizontal section of the same, taken in the line y y, Fig. 1 5 Fig. 4, an enlarged detached view ot' a pinion pertaining to the same, with the .parts to which it is connected, the latter beingin section, as indicated by the line zz, Fig. 3.

Similar letters of reference indicate corresponding parts in the severa-l figures.

This invention consists in having the lower hinge ofthe blind formed of a semi-spherical socket provided with an internal gear, into which a screw meshes or Works, the screw leing on a shaft which is fitted in a tubular shaft, the latter passing horizontally through thejainb of the window-frame, and having a pinion upon it which gears into a segmentrack at one end of the lever, the latter being attached to the slatrod of the blind, and all arranged in such a manner that the blind may be opened and closed from the inner side of the window without raising the sash, and the blind-slats also opened and closed, as hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the frame of a window; and B a blind, which may be constructed in the usual way, and attached to the frame A by hinges C O', the upper one, G, being constructed in any proper manner,but the lower one,C/,con strueted in a novel way, as follows: The part A ofthe hinge which is attached to the blind is of hollow semispherical form, and has teeth e within it, which extends all around, and into which a screw, b, gears a pin, c, on an arm, d, which is attached to the frame A, fitting centrally into the upper end of a, as shown ink jamb, e, of the frame A, and into a tubular shaft, E, which extends entirely through the janib e, and is provided with a crank, F, at

its inner end. The shaft D has a collar, f, upon it which bears against a plate, g, on the outer side of the jamb, and it also has a collar, h, upon it at the inner side of said plate g. This plate g, which is secured to the jamb, and the two collars f h, prevent the shaft D from having any longitudinal movement, as will be fully understood by referring to Fig. 3. The orifice t' of the tubular shaft E at its inner end is square, and when the shaft E is shoved inward or toward the hinge C covers a square, j, onk the shaft D, so that when the shaft E is shoved inward and turned the shaft D will be turned with it, and the screw b, in consequence of gearing into the teeth a of the semi-sphere a., will open and close the blind B, and also secure lor hold the same at any intermediate point between an open and a closed state. The inner end of the tubular shaft E is provided with a flange, k, having a tooth or projection, Z, which, when the shatt E is pulled outward, catches into one of a series of holes, m, made in a pinion, G, which is fitted loosely on the shaft E, and is thereby made to turn with the latter. When the shaft E is thus pulled outward in order to connect the pinion G with it, the inner end of said shaftis off from the squarej on the shaft D,and consequently the screw b is not turned when the pinion G is turned, and when the shaft E is shoved inward, so that its orice 'i is over the square j, to turn the screw b, the projection l will be out from the hole m in the pinion. It will be seen therefore that the screw b and pinion Gcannotbe simultaneously turned by the shaft E.

H is a lever which is attached by a fulcrumpin, n, to the inner side ofthe blind B. One end of this lever is connected to the lower end of the Slat-rod I ot' the blind, as shown at o, and the opposite end is provided with a segmentrack, p, into which the pinion G gears; hence it will be seen that when the pinion G is turned the slats g of the blind will be opened and closed, and that they may be retained at any point between an open and closed state.

opposite end` with :L segment-rack, p, with which J:he pinion G gears the shaft'J D E, being` connected and disconnected7 and the pinion G connected with and disconnected from the shaft E, as shown, and all arranged to operate substantially as and for the purpose specified.

OBEN WILLIAMS.
