IMPaoynn INSIDE WINDOW-BLIND.

`TO ALL WHOM IT MAY CONOERN':

Be it known that I, S. W. SHOREY, of Galesburg, in thecounty 4of Knox, and State of Illinois, have invented a new and improved Inside lliindcw-Blind; and I do hereby declare that the following is a full, clear,

and exact description thereof,'which will enablethose skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specification. 9

This invention relates to anew and improved method of constructing and operating inside blinds for the windows of dwellinghouses and public buildings g and the invention consists in the peculiar manner in which the slats forming the blind are connected together, andiu the manner in which they are closed, and secured 'in a closed position, as will be hereinafter more fully described.

Figure 1 is a vertical front view of the blind, partly iu section, represented as it appears when attached to the window, with the slats open.

Figure 2 is a; side view ot' the same.A

Figure 3 represents a sidewview of the blind as closed.

Figure 4, a top view ot' the blind.

Figure 5 is a detached view of one of the slats.

Similar letters of reference indicate corresponding parts.

This blind is composed of slats, constructed of wood or metal, similar to those in ordinary use, and of two 'distinct frames, to one of Whichframes the s lats`are secured or hung, and which is attached to the inside of the window, being stationary. The otherframc is connected with the first by metalli-c straps, which form ajointed connection, the dutyof which frame is'to closethe slats of the blind andsecurethem in a closed position.A

A represents vthe first-mentioned or stationary frame, which -is permanently attached to the window. B is the other, or movable frame, which is connected.- with A by the straps C, as seen in the drawing. D represents the slats. I -The form of the frame A is seen more distinctly in -g. 4. The upright vpieces of both frames are grooved or recessed, as seen'at a, toalIOWthewcbbing by'which the slats are connected together to work up and down without friction or wear. This-webbing is attached to both edges of the slats, atpeach end, by cords, or wires passing thrcughholes in each edge of thc'slats, as seen in iig. 5. c represents thc webbing. E represents the lifting-cords, which passover pulleys d, in the top rail of the stationary frame, as seen in figs. 1 and 4. The cords pass down through holes near the ends= of'the slats, and are attached to the lower slat. The upper'ends of these cords are brought together, as seen in the drawing, tig. 1, at E. It will be seen that the arrangement is such that, by pulling down 'on the united cords, or on the tassel f, the slats will be raised, and occupy a space in the upper partof the window corresponding to their combined thickness,-when their sides are in close contact with each other. The inner sides ofthe slats, at each end, are grooved or cutout to make room for the cord, so that they may lie close together when closed, as seen in iig. 3. In the, position of the blind seen in iig. .3, the frame B is closed down tightly on to, the slats, in which position it may be scoured on the inside, by hooks or bolts,thus giving the window the protection afforded by a close inside'shutter, but with the superior advantage of being entirely opened and closed at will, and much more conveniently. When the slats are let down, they naturally assume the open position seen in iig. 2, from their own weight o r gravity. To close the blind, as seen in iig. 3, theframe B is pressed against the slats. The upward motion given it by the straps C in this operation serves to raise the edges ot" the sl'ats and fold them together.

In this example of my invention, the sides ofthe frame B are'not rigidly connected, but they are united in such a manner that they may act independently of each other. The sides are connected at top and bottom by wires or rods, g; but this arrangement is by no means necessary for the proper working of the blind, as a rigid frame would serve the same purpose, and, perhaps, be morevconvenient. h represents knobs on the frame B, for operating or raising the frame.

Having thus described my invention, I claim as new, and desire to secure by Letters Patentv 1.An inside window-blind, constructed, arranged, and operating Asubstantially as herein show'n-nnd described.

2. The combination of the frame A, having the grooves a, webbing c, slats D, frame B, and hinges C, as herein described, for the purpose specified. y l l l 3. The combination ot' the adjustable frame B with the grooved frame A, for closing, and holding 'in a closed or partially closed position, the slats ot' a window-blind, as herein shown and described.

The above specification of my invcntionsigned by me, this 12th day cf September, 1867.
