wmnow-Bmnn Specificatidn of Iietters' Patent.

Patented May 25, 1909.

Application filed April 25, 1908. Serial No.429,269.

To all whom it may concern:

Be'it known that I, GEORGE P. MITCHELL, a citizen of the United States, residing at Shenandoah, in the county of Page and State of Iowa, have invented a new and useful Window-Blind, of which the following is a s ecification.

. he object of the invention is to provide a blind that shall be capable of ready adiust-- ment to window frames of different wi ths,

and which may be disposed either above the,

-- upper or below the lower sash,-and which s all be of such construction as to allow free passage of air through a room but at the same time positively preclude theentrance of rain, whereby it will be unnecessary to close the windows during a rain storm, thereby obviating a source of considerable discomfort to the occupants, the storm be of long duration.

Furthermore, it 1s one of the objects of the invention to render it possible to air ahouse,

- an ofiice or any style of building, either pubtaken from a view 1n vertlcal transverse section, taken All of the parts of the lie or private, while the tenant is absent, and

.without subjecting the latter toworry from fear that rain will beat in the windows.

"With the above and other objects in view,

as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of 'parts'of a window-blind, as will be hereinpfter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in'which like characters of reference indicate correspondmg parts, Figure 1 is a view in elevation the front of the blind. Fig. 2 is on the line 22 of Fig. 1, and looking in the direction of the arrow.

The blind comprises two stiles 1 andv 2, a plurality ofslats 3 carried by the stile 1, a plurality of slats 4 carried by the stile 2, and a keeper 5 secured to the inner terminals of the slats 4. j

blind are, by preference, made. of galvanized iron, on account of its strength, and rust-resisting qualities; but any other sheet metal may be utilized -fo r the purpose that may be found applicable therefor. t

Each of the stiles 1 and is a trou h-like structure, and between the flanges 6 t ereof the outer terminals of the slats are secured,

as by soldering. In order torender the slits thoroughly, effective for preventing enolpposed faces of the flanges 6, s o

the rear edges 8 especially if the article,

simple in character, will be found thoroughly trance of rain between them, and also to provide for a stable attachment between them and the flanges 6 of the stiles, the outer edges 7 of the slats are turned downward, and their inner ends8 are turned upward, and these to the upper edge of tension 10 and 11- respectively in front of of the slats 4 to which it is which the lower sash rail is ada ted to rest,

and to the extension 11 the eeper 5 is soldered.

In order to stay the extensions 10 and 11,

and also to impart a finished. appearance to 12 of which are downturned and are secured by solder to the inner faces of the front flanges of the stiles and to the extensions 10 and 11 of the slats 3 and. 4.

stiles, they will have the appearance of being continuations of the same and will therefore materially add to the mechanical structure of the device.

As a means for limiting the outward movement of the two sections of the blind, the upper and lower slat of the series 3 is provided with an outturned toe 13 which, by

- contact with the keeper 5, as shown in Fig. 1,

will secure the object sought.

The improvements herein defined, while eflicient for the purposes designed, and wil result in the production of a durable and in expensive form of window blind.

I claim A blind comprising two sections arranged for sliding movement relative to each other,

As these bracesare of the same width as the flanges of the there is a brace 12 employed in connection with each of the stiles, the edges each section comprising an upright stile and the upper slat of each set being provided with a vertical extension; a guide having its laterally extendmg slats mounted thereon,

upper'te iminal rigidly attached to the yer tic, 1 extension of the upper slat of one of the sets, the free termina of the guide bein carried downward in contact with the rear In testimef y that I claim the foregoing as edges of the slats of both sets, being passed a my own, I have hereto affixed my signature beneath the slats, and thence carried upward in the presenceof two witnesses.' 1 in contact with the forward edges of the slats GEORGE 'P.
