v l kf IMPROVEMENT IN BLIND-CATCH.

The Schedule referred to in these Letters Patent and making pax-t o! the lame.

To all whom it may concern:

n The catches now in use for blinds are all open to l criticism from the fact that when the blind is to be closed, it is necessary to raise the window some distance, and extend the arm and hand, in order to reach the catch,rbefore it can be released from its attachment tothe house.

In -stormy weather, whether in summer or winter, this necessarily-exposes the person, and not unfrequently in driving storms the rain or snow beats into the room.

To obviate this difficulty, by means at once simple, cheap, and eiective, is the purpose of my invention.

My device is the application of a lever to a blindcatch, said lever having an arm long enough to extend to the inner edge of the blind, by means of which the catch may be detached from its fasteuings without extending the arm or raising the window more than a few inches.

This arm also closing the blind.

The operation pf my invention will be readily unde'rstood by reference to the drawings. a shows the lever attached to the catch b, which has the spurs o and d, the former catching when the blind gives a leverage, which assists in Yis open and the latter when it is shut. (See fig. 2.)

The spring shown at e is a spiral.

-The catches and spring are here enclosed in a box, f, to which a cover is secured by a screw passing through g, which also serves as a pivot for the lever. `An opening in the box at i j allows the lever to swing a proper distance, and the edge j serves as a bearing-shoulder, or fulcrum, for the arm when einployed to draw the blind to, after it has been released from the wall of the house.

The length of the lever-arm is shown in iig. 2, as are also at h, the stubs or staples on the window-sill and house.

The end of the lever-arm is formed into a ring for the nger.

When the blind is to be closed, the window is raised to a sufficient height to allow the hand to be 'put out.

Oatchin g the ring. with the fore-inger, the lever may be drawn out a short distance beyond the blind, disengaging the catch.

It will be observed as a point of -convenience that the same motion which frees the blind draws it toward the window, requiring the exertion of but very little strength.

From the slight distance to which it is necessary to raise the window, no water or snow can enter, and only the hand need be exposed.

The catches c and d, shown in the drawing, enclose the staple on three sides, thus preventing the usual objectionable rattle in windy weather. i l v I do not claim the spring-catch, nor the method of its attachment to the blind; neither do I claim operating the spring-catch by a lever.

J. Gurriexs patent, No. 72,609, December 24, 1867, is dierent from mine in construction, and is not intended to e'ect the same purpose, and I do not claim the subject of his invention.

. The particular object of my invention is 4to produce a blind-catch by which the blind, whenyopen, can be unhooked and swung to by an elongated lever, the inner end of lwhich is so near tothe window that a person is not compelled to stretch the body out of the lwindow in order to reach the catch, but simply to extend the hand far enough to reach the bottom edge of the blind next 4to the window, to which point the elongated lever extends. i

My device is attached t'o the bottom edge of the blind, and the lever a swings or is operated in a horizontal plane; but

What I do claim as my invention, and desire to secure by Letters Patent, is

A blind-catch, constructed and arranged as herein set forth and described.
