IVIETIAL WINDOW-SCREEN.

' Patented. Jan. 250, 1906.

Application filed November 14, 1905. Serial No. 287,273.

To all whom it may concern: I

Be it known that I, ALLEN H. MIX, of Burlington, in the county of Chittendenand .State of Vermont, have invented a new and- I the wire-cloth.

I shall proccedto describe in connection with the accompanying drawings, forming part of this specification, the screen construction in which my invention is embodied and will then point out in the claim that which I believe to be new andof my own invention.

In the drawings, Figure 1 is a face view of the screen, the center portion of it being broken way to reduce its dimensions. Fig.

2 is a cross-section of one of the frame-bars be mitered and welded or soldered together,

or the bars at these points may be secured together in any other suitable way, my present invention having to do only with the construction of the frame-bars. Each bar A is made of a strip of sheet metal which is bent into a box-like hollow structure of rectangular form in cross-section with parallel sides and top and bottom, the top, however, not being completely closed, but being formed by inturned portions a, extending toward each other in the same plane from opposite sides of the bar with an openingb between their opposed edges. Each filling-strip O is made i'rom shect metal bent so that it will have a channel-bar or L] form in cross-section. It is of a width to fit and fill the opening 1) between the op osed edges of the limbs a of the bar A, and

its free ends are bent slightly inward toward, each other, so as to facilitate the entrance of the filling-strip into the opening I).

The edge of the Wire-clothis laid over the" opening I) so as to partly bridge the latter,

and then the filling-strip is pressed down into the opening, bending down in its course the wire-cloth, which is caught and held, as shown in Fig. 2, between the edge of one of the limbs 11 and theadjoining side of the filling-strip. The farther the strip is pushed" down the tighter is the grip on thecloth, until by the time the fillmg-strip is forced home the head of the strip will be between the edges of the limbs a, which act as bitingjaws to grasp and hold the parts most firmly in position. At the same time it' will be noted that by means of a proper tool the fill- 'ing-strip can be easily lifted out and removed from the frame-bar whenever it is desired to remove the wire-cloth.

"The form of the frame-bar A itself, with inturned limbs a lying in the same plane, 1m-

parts to the bar great stiffness and strength,

and as the filling-strip is grasped only by the opposed biting edges of these'limbs the arrangement is such that the thrust of the filling-strip on these limb's a is effectively resisted. v

I am aware that it is not new to use a longitudinal filling-strip applied to and fitting with a longitudinalopening. b between their opposed edges, in combination with a sheetmetal filling-strip, of substantially channelbar or [H] cross-section to fit and fill said opening, an wire-cloth gripped between one side of the filling-strip and the op osed biting edge oftheadjoining limb a, o the bar, as and for the purposes hereinbefore set forth. In testimony whereof I affix my signature in presence of two witnesses.
