WIN DOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 369,261, dated August 30, 1887.

Application filed June 8, 1887. Serial No. 240,646.

To aZZ whom it may concern.-

Be it known that I, SAMUEL RoEBUoK, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvementsin W'indowScreens; and I do declare the following to be a full, clear, and exact dcscriptionof the invent-ion,such as will enable others skilled in the art to which it ap'pcrtains to make and use the same, reference bei ng. had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Hy invention relates to window-scrcens which have wire or other woven netting applied to them, and it consistsin a novel manner of constructing the wooden uprights of the frames with kerfs, as well as joint framinggrooves, whereby frames can be constructed as heretofore with rabbets and couplingtongues, and to afford facilities whereby the said netting can be confined at two of its edges in said kerl's and fastened by brads or nails made without heads, and the othertwo edges can, if desired, be confined by surface-finishing moldings abutting against shoulders and fastened by similar headless brads or nails.

In the accompanying drawings, Figure 1 is a front elevation of a well-known style of'extension window-screen, the same having my invention embodied in it and being partly extended. Fig. 2 is a top view of the same. Fig. 3 is a horizontal sectionin the-liney yof Fig. 1. Fig. i is a perspective view of my improved extension-screen partly extended, and Fig. 5 is a broken section.

The window-screen represented comprises two wire work or woven screens, A A, fastened in frames B B,which are coupled and fitted to slide upon one another by means of rabbet grooves 51 g ofthe horizontal guiding portions (1. c of said frames, and tongues 9", formed on two of the upright portions a a. of the frames, said frame portions cut on which the tongues are formed entering, by means of their tongues 9 the rabbets g g, and at the same time occupying a position so close to the screen material A A as to prevent insects entering the room between said screen material and their edges, which nearly touch the same, while one frame (No model.)

is being slid upon the other for the purpose of extending the screen, as well as while at rest. The tongues and rabbet grooves, though old, are importantin this particular construction of window-screen, and while I retain the same I have changed the construction of the upright portions a c by increasing their crossscction area, so as to provide in them the framing-grooves 71/ h to receive the shouldered ends 9 g of the horizontal portions a a; and on one side of the rabbeted portions a a, I form the kerfs b b, with one of their surfaces just about flush with the surface of said horizontal guide-pieces a a, as shown, while the other broad surfaces of the kerfs stand beyond the same to the extent of the thickness of the woven screen material A A, which is placed into said kerfs. seen, are located behind the screen material A of one frame B, and in front of said screen material in the other frame, and, as above stated, serve to receive the tongues g and act as guidesto and meansi'or coupling said frames. The kerfs b b are of a width corresponding to the thickness of the screen material,and are of a depth, as shown, sufficient to retain the said screen material in position after it has been bent into a curved form and sprung into them, or otherwise applied.

Then the wire screen material or other The rabbets g y, it will be woven fabric has been placed into the kerfs Z1 b, tacks f with narrow heads or headless brads are passed into the wooden uprights a a and through the wire or other screen material, as shown, and in addition thereto suitable tacks or nails, f, are also passed through the screen material into the horizontal pieces a a of the frame B B, or, if deemed desirable, finishingmoldings 0 C may be fitted upon the exposed edges of the screen material and fastened by headless brads passed through them and the screen material and into the horizontal guiding portions a a, as shown.

It will be seen that the up rights a a, in which the kerfs b b are formed, are made thicker in cross-sectional areathan ordinarily, and that shoulders are formed against which the ends of the finishing-moldings C O can abut, said moldings lying just flush with the surfaces of 1100 while the necessity of using large-headed nails is avoided.

By my invention considerable expense is avoided in manufacturing the particular window-screen frames, B B, herein shown, and, while this is so,these frames are rendered more serviceable and can be put upon the market in a neater shape and at less cost than heretofore. The lumber for forming. the upright frame portions a a can be formed by machinery,with the framing joint-grooves h h, and in addition thereto with the kerfs b b and ornamented surfaces z produced by similar means, and in this form "furnished to window -screen-frame makers along with the rabbeted and shouldered horizontal portions a aatless cost than separate framing-lumber and separate moldings for the uprights a a can be produced.

This invention is specially useful and important in connection with the style of manufacture represented, inasmuch as the cost of window-screens must be very slight in order to meet the demands of the public and the trade.

I am aware of Letters Patent Nos. 108,348, 211,962, 257 ,348, and 334,876,wherein kerfs for receiving wire or screen material are shown in various ways, but different from the construction shown by me. Ialso am aware of Letters tongue frame-pieces are shown; but these do not provide kerfs at the outer surfaces of the rabbets in solid portions of the frames. My improvement combines the kerfs and rabbeted and tongued frame-pieces in a very useful and new way, avoiding in this special character of window-screen, which is acknowledged to be the best in use, the extra expense of finishing moldings, as hereinbefore described.

What I claim, is-

The window-screen composed of two parts, 13 B, having solid upright portions a a, provided with kerfs b b, tongues and joint framing-grooves, and parts a a, provided with shouldered tongues adapted to be received by said grooves and having rabbcts g g, in which the tongues slide, and the said kerfs being flush with one of the rabbeted surfaces of the parts a a, substantially as and for the purpose deseribed.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL ROEBUGK.
