ADJUSTABLE wINDcw-sonnnn'.

To all whomat may concern: j

Be it known that I, ADAM J. BAUER, a citizen of the United States, residing at Owego, in the county of Tioga, State of New York, have invented certain new and useful Improvements in Adjustable Window-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable lothers skilled in the -art to which it appertains to make and use the same.

This invention relates to window screens and has for an object to provide a window screen that may be adjusted to fit any size of Window and may be then locked in such adjusted position so that it will always be adjusted to that window.

A further object of the invention is to provide an extremely simple and inexpensive window screen that will be formed of a few parts that will not easily get out of order.

With the above objects in view the inventionconsists of certain novel details of construction and combination of parts here'- inafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawingillustrating this invention z-Figure 1 is a front elevation of the screen." Fig. 2 is a longitudinal sectional view through the window screen, on the line .2--2 Fig. 1. Fig. 3 is a cross sectional view through the window screen on the line 33 Fig. 1. Fig. 4 is a rear elevation of the screen showing the same in position for adjustment to a window prior to being locked in such adjusted position,

with the nuts shown 1n dotted position to lock'the screen in adjusted position.

Referring now to the drawing in which like characters of reference designate simi- .lar parts,

the screen is shown to comprise a pair of oblong frames 10 and 11 placed end to end and joined together at their confrontd ing ends by a pair of spaced-tension devices Each frame'is equipped on the outer end bai` with a friction element 12 of rough material. l U Each tension devlce comprises a bolt 13- which asses throu h the confronting end bars. 1 and 15 o both framesand is equipped between-the bars with a helical Specication of Letters Patent.

spring 16 or other spring that will serve to urge the frames apart. 'I he head 17 of the bolt bears against the inner face of the end bar 14 of one frame and the nut 18 of the bolt is tightened up against the inner face of the end bar 15 of the other frame.

The frame 11 is equipped on the top rail and the bottom rail with respective channeliron guide extensions 19 and 20 which slidably receive the corresponding rails of the frame 10 and are each formed of a single sheet of metal bent upon itself to produce a double angle iron structure as shown, this construction serving to firm] hold the screen elements about to be escribed in place.

A screen element 21 is stretched over the frame 10, and a similar screen element 22 1s Y stretched over the frame 11, these elements being held firmly in place by the channeliron extensions 19 and 20. Both channel iron extensions are connected by a single u right metal bar 23 which serves to hold te extensions in rigid spaced relation so that binding of the frames will be positively prevented during their relative movement toward and away from each other. It will be noted that the screen elements are substantially incontinuation with each other so that the screen presents a substantially fiat 4surface on one side from end to end.

screen has been adjusted to a. window it can p be easily removed or replaced by pressing the frames 10 and 11 together against the pressure of the springs 16. l

From the above description it will be seen that I have provided an extremely simple and inexpensive screen that may be adjusted to windows of various sizes and may be locked in any adjusted position, and further that the screen is formed of a few strong and durable parts that will not easily get out of order.

9o p l itv said trame including l the two What is claimed, is

1. An extensible screen said frame including a transverse bar, guide members carried bythe frame, and extending beyond the transverse bar, a fabric stretched over the frame'and extending beyond the transverse bar, a second trame engaged slidably in the guide members, and Ahaving a transverse bar lying between the guide members, a fabric stretched over the second frame, and tensioning devices engaged between the 'two transverse bars to hold them yieldably against movement toward each other. y

A2. An extensible screen including a frame, a transverse bar, guide members carried by the iframe, and extending beyond the transverse bar, a fabric stretched over the frame and extending beyond the transverse bar, a second frame engaged slidably in the guide members, and having a fabric stretched over the second frame, tensioning devices engaged between transverse bars to hold them yieldably against movement .toward each other, and means for limitingthe movement of the transverse bars away from each other'.

3. An extensible screen including a frame, said frame including a transverse bar, guide members carried by the frame, and extending beyond the transverse bar, a fabric stretched over the frame and extending beincluding -a frame,

. of frames,

` yond the transverse bar, a second frame enm the guide member, and

gaged slidably having a fabric stretched overthe second frame, tensioning devices engaged between the two transverse bars to hold them. yieldably 'against movement toward each other, and adjustable means for limiting the movement of the transverse .bars away from each other. 1

4. An extensible screen including a pair a fabric element stretched over each frame, guide members carried by one frame slidably receiving the other frame, and tension devices connecting both frames,

each tension device including a bolt passed through the confronting end bars of both frames, a helical spring on the bolt between said bars serving normally to urge said frames apart, the head of said bolt bearing against the vinner face of one of said bars, and a nut on said bolt bearing against the inner face of the other of said bars, said nut being positionable at various points on the end of said bolt to limit expansion of said spring and hold said frames anchored at a i predetermined relative position.v

In testimony 'whereof,`I aiiixmy signature,

in the presence of two witnesses.
