DANIEL HARTLICY, OF OLATIIE, KANSAS.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 417,179, dated December 10, 1889.

Application filed June 13, 1889. Serial No. 314,083. (No model.)

To all whom t may concern:

Beit known that I, DANIEL IIARTLEY, of Olathe, in the county of Johnson and State of Kansas, have invented certain new and useful Improvements in Vindow-Screens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specific-ation, and in which- Figure I is a perspective view of my improved screen in position, showing a portion of the wire-gauze broken away in order to more clearly illustrate certain portions of the device. Fig. II isa vertical section taken on line II II of Fig. I. Fig. III is a transverse section taken on line III III of Fig. I. Fig. IV is a front view of one of the screenguides. Fig. V is an enlarged detail perspective view of the screen-frame.

My inventionrelates to an im provementin window-screens; and it consists in features of novelty hereinafter described, and pointed out in the claims.

Referring to t-he drawings, l represents the window-frame, to which is attached two guides or strips 2. The guides 2 serve to hold the screen in position inthe frame, but permit it to move or slide in a vertical direction.

-i represent the frame, which is made in four sections, the sections being riveted to each other and to the wire-gauze 5. I form the screen-frame of metal, and prefer to make it of tin, but do not coniine myself to this material. The top and bottom sections 3 of the frame are formed into a T shape, the ribs 6 servingto strengtl'ien the frame and to give the same a neat appearance.

8 il represent two parallel extensions ol' thc frame, between which the top and bottom of the wire-gauze is clamped. The gauze may be further secured by rivets passing through the extensions and the wire-gauze. The side sections l ofA the frame are formed with V-shaped extensions 10 l1, a rib 12, and parallel extensions 13 la. Between the parallel extensions the side of the gauze is held. The extensions may be held firmly together by means of rivets. Between the V- shaped extensions 10 11 are V- shaped grooves l5. The guides E. it into the V- shaped grooves 15, thus forming a guideway between thc screen and the window-frame, and

as the guides fit loosely in the grooves the screen may be raised or lowered at will, and as the guides only extend about half-way up the window-frame it will be seen that the screen may be removed entirely when so desired. The rib 12 gives strength to the frame, the same being essential, as where the frame is made of so light a material as tin itis necessary that it be formed in such a shape as to give it strength.

1G represents a clamp or bracket which extends in a transverse direction across the screen, and whichis riveted thereto. To this bracket is secured a rubber strip 17. The object of the strip 17 is to ll up the space between the screen and the window-pane (see Fig. I) in order to prevent insects from passing through between the screen and pane when 'the lower sash is only raised a portion of the way.

1S represents the window-sash, and 19 the window-panes.

By my improved method of making the very light material (such as tin) and still make the frame perfectly rigid. The sections may be stamped ont and then formed into the shape described, or otherwise manufactured, as may be desired.

I claim as my inventionl. As a new article of manufacture, a window-screen frame formed of thin metal having V- shaped grooves and strengthening-ribs projecting at an angle to the frame, substantially as set fort-h.

2. A win dow-screen frame composed of sheet metal having V-shaped grooves in its outer edges and strengthening-ribs projecting at an angle to the frame, substantially as set forth.

3. In a window-screen, the combination of the top and bot-tom sections of the frame formed of sheet metal bent substantially in a T shape, and the side sections of sheet metal formed with a strengthening rib, said T- shaped projection and strengthening-rib extending beyond t-he line of the screen in order to protect the same, substantially as described, and for the purpose set forth.
