UNITED STATES PATENT OFFICE.
THOMAS W. DOWLING, OF DETROIT, MICHIGAN.
WINDOW-SCREEN.
EPECIPICATION forming part of Letters Patent No, 380,747, dated April 10,1888.
Application filed August 15, 1887. Serial No. 246.958. (No model.)
To aZZ whom, it may concern:
Be it known that I, THoMAs W. DOWLING, a citizen of the United States, residing at Detroit, in the county of tVayne and State of Michigan, haveinvented certain new and usefulImprovementsinWVindow-Screenspfwhich the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to new and useful improvements in adjustable window-screens; and the invention consists in the construction of different parts and in the peculiar combinations and arrangement of parts, all as more fully hereinafter described and claimed.
In the drawings which accompany this specification, Figure l is a perspective view of my window-screen, looking at its inner face. Fig. 2 is a similar perspective view, but looking at its outer face, and with one of the adjustable wings detached and shown separately. Fig. 3 is a vertical central section of the screen. Fig. 4 is a vertical section through a window sash and frame to which my screen is applied. Fig. 5 is a horizontal section of Fig. 4. Fig. 6 is a perspective View corresponding with Fig. 1, but with the side rail differently secured.
In the drawings, A and B are the top and bottom rails. G O are the side rails, and D is the wire-gauze secured thereto. The top and bottom rails, A and B, are preferably made of a length to suit the greatest normal width of windows, and the side rails are secured to these top and bottom rails to fit the smallest normal width of windows. The side rails are preferably let into the top and bottom rails, as shown in Fig. 1, so as to bring them flush with the top and bottom rails on what is to be the inner face of the screen, and when this mode of securing them is used the side rails are made of thinner stuff than the top and bottom rails, so as to be of a thickness corresponding with the width of the parting-strip in the windowframe, for a purpose which will appear hereinafter.
Instead of securing the side rails as just described, they may be secured on the outside of the top and bottom rails, as shown in the modified construction in Fig. 6, which in all other respects is identical with the screen in the other figures.
E are extension-wings slidingly secured by engaging into grooves F, formed in the upper and lower faces, respectively, of the top and bottom rails, said guide-grooves being prefer ably formed two-sided only,with a corresponding bevel formed in the ends of the wings for the purpose of least affecting the strength of the rails, and for convenience in manufacturing these grooves may extend the whole length of the top and bottom rails.
The extensionwings E form a close joint with the side rails for the purpose of excluding insects, and they are of suitable width to afford adjustability within the usual limit required by the difference in the width of the window-sashes.
G is a stop or rest pivotally secured to the under side of the upper rail of the screen, and this stop I preferably make of one piece with its pivot, which is screw-threaded, and may be easily turned underneath the rail to be out of the way when not required, as hereinafter described.
In practice, to fit a screen so constructed to a window, I saw ofi the ends of the top and bottom rails, so that they will fit in length between the parting-strips of the window-frame. Then I extend the wings until they abut against the window -jamb with their outer edges, as shown in Fig. 5. In this position I then secure the screen, preferably by means of little strips H, nailed in the corner between the window-jambs and the extension-wings and to the outside thereof. The top and bottom rails being of a relative thickness, as described, it will be now seen that the lower sash may be freely raised and lowered without removing the screen, and by turning the pivotal stop G forwardly the lower sash in its upraised position may be supported thereon and held against accidental displacement, as shown in Fig. 4, wherein it is also shown how the top rail, in connection with the window-frame of the lower sash, forms a tight joint without the interposition of a flexible strip, as used in other constructions heretofore. Should it be desired to remove the window-screen, the same is ac- I complished easily by withdrawing the wings from between the parting-strip and the strip H. Instead of the strips H, other means for preventing the screen from falling outside may be used.
I am aware'of the Patent No. 329,287, dated October 27, 1885, in which there is made use of aso-called keeper to keep the screen in position. This construction I do not consider to be of practical value for screens which are manufactured for the trade, on account of the variable thickness ofwindow-sashes, and, moreover, if such a keeper is used the windowscreen will be deprived of its hold Whenever the lower sash is closed, and the advantages to be derived from a screen stationarily secured under the upper sash are altogether lost. By arranging the extension-wings so as to be on the outer face of the screen, and letting the top rail of the screen project inwardly, I produce a perfectly-tight joint, insect-proof, without any further means, as required in the patent alluded to, and I therefore succeed in gaining the objects described in a more economical and efficient manner.
What I claim as my invention is- 1. In a window-screen, a frame consisting of top and bottom rails of a length to suit the greatest normal width of window-sashes, and of side rails secured thereto at a distance apart to suit the normally-smallest width of window- 25 sashes, said top and bottom rails being provided with a two-sided groove, one side being beveled, as shown, and the wings having a corresponding bevel engaging said grooves, substantially as and for the purpose described.
2. In a window-screen, the combination of a frame consisting of top and bottom rails of a length to suit the greatest normal width of window-sashes, and of side rails secured thereto at a distance apart to suit the normally-smallest 3 5 width of window-sashes, and of extension-wings slidingly secured between the top and bottom rails and at a distance from the inner face of the top and bottom rails equal, or nearly so, to the width of the parting-strips, substantially 0 as andvfor the purpose described.
In testimony whereof I affix my signature, in presence of two witnesses, this 2d day of Au- Witnesses:
