To all whont it may concern:

Be it known that I, MARSHALL B. BURK,

a citizen of-the United States, residing'at Prescott, in the county of Walla Walla and Territory of Washington, have invented. certain new and usefullmprovements in .Windows 5 and I do declare the following to be a full, clear, and exact description of the'invention, such as will enable othersskilled in the art to which it appertains to make anduse the same,

reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to windows; and the and, comprises the top A, "sill B, and sides B andB. The sides are provided with strips 0, between which the sashes D are fitted. .There may be as many of these sashes as desired, the

number beingimmaterial to the spirit of,,my

invention.

It may be greater or less than that shown, which represents three sashes. They are pivoted by L-angled plates E, "which are secured to the side rails of the sashes, and have the parts E standing at right angles, to the 'plane of the sashes and resting against the inedge of one of the strips 0, and is held from It is located alongside the lateral displacement by keepers G, and has a vertical reciprocating movement. The lower end,which extends within convenient reach, is provided with a handle, 9, aid has a longitudinal slot, f, through which a set-screw, H, is passed and screwed into the frame for fastening the rodat any stage of its movement and holding the sashes at any desired adj ust-' ment.

It will be observed that the means. plates E-are the same as those used for swing; ing the sashes, and the edge of the side Eis provided with teeth 0, which differ in form from the others; but this departure is only one of taste, and not one affecting the vital point of the improvement. The sash is swung held at any adjustment by a spring-catch, I, secured to the frame, engaging the propertooth on the part E of the plate E. The adjacent.
