' WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 594,606, dated November 30, 1897. Application filed March 5, 1896. Serial No. 581,390. (No model.)

To all whom it may concern:

Beit known that I, E GENE COOK, a citizen of the United States, residing at the city of Niles, in the county of4 Berrien and State of Michigan, have invented a certain new and useful Improvement in Window-Screens, of which the following is a specication.

My invention relates to improvements in window-screens.

The objects of my invention are, first, to provide a window-screen which can be quickly and conveniently attached to the window casing or frame without the use of frames or other cumbersome means; second, to provide a window-screen for the entire window which can be easily placed on the outside windowcasing from the inside ofthe window; third, to provide an improved window-screen so constructed that the frame can be dispensed with and cross-bars substituted at the top or bottom and .the screen drawn tight between them. Other objects will appear more deiinitely in the detailed description. I accomplish these objects of my invention by the devices and means described in the following specification and illustrated in the accompanying drawings, in Which- Figure lis an outside view of a window with one of my improved screens in position, portions of the screen being broken away to show the character of the adjusting devices. Fig. 2 is a vertical sectional View on line 2 2 ofvFig. l, looking in the direction of the little arrows at the end of the sectionlines. Eig. 3 is an enlarged detail elevation of one of the tension devices. Fig. fi is a sectional view on line 4 4 of Fig. 3, looking in the direction of the little arrows at the ends of the section-line. Fig. 5 is an enlarged detail View of one of the lower corners of the Fig. 6 is an enlarged detail View of one of the upper corners of the screen, as shown.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A represents the window-casing, which can be either an outside or an inside Windowcasing.

B represents the screen held in place. The cross-bar D is secured by suitable means to the lower end of the screen and is held securely in place` against the bottom of the window casing or frame by the brackets E E,

which extend outwardly and slightly downward to engage the bottom bar D securely, as indicated in Figs. 2 and 5. A bar O extends across the top of the screen and lits Within the window casing or frame. A molding or straight strip O is secured to the outside of this cross-piece O and affords an attachment for the screen beyond the inner edges of the window-casing. A notch a" is cut or mortised into the top bar O, between it and the molding O'. To each side of the window-casing at the top a bracket F is secured, Within which a bolt or bar G reciprocates. On the upper end ofthe bar is an ear a, which fits into the notch c to retain the bar O in its proper position. A point A projects into the under side of the cross-bar O to hold it' securely. The bottom part of the bracket E is supplied with rack-teeth. The lower end of the bolt G projects slightly outward, and to it is pivoted the lever H. Upon the lever I-I is a pawl or dog I for engaging the rack-teeth H, and itis pivoted at a point which lies within a line through the center of the .pivot between the lever and the bolt and t-he point of 'contact with the dog and the rack. It will be seen that Ywhen the lever is pressed close to thebracket F the pivotal point of the dog I will pass the dead-center,and the lever will be automatically locked. A number'of teeth are provided on the rack to permit of a properadjustment to put due strain upon the screen B, so that its edges will come close enough to the Window-casing to prevent the passage of insects.

place the screen over a window from the inside without the use of ladders or scaffolding.

I desire to state that my improved windowscreen can be considerably varied in its details Without departing from my invention..

ICO

The fastening devices can be located at the bottom, with the brackets E at the top of the window, and in narrow windows the bars can be placed upon the sides of the window and the corresponding change of the position of the fasteners and brackets made. Other styles of fastenings might be used where a window screen and the cross-bars are constructed as I have indicated and the screen still beattached to the window from the inside.

IIaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a window-screen, the combination of the window-screen B, cross-bar D at one end thereof the brackets E, E, on the window casing or frame to engage said cross-bar; crossbar O with notches a therein; molding C/ clamping the screen onto said bar O at the opposite end, so that the molding shall project beyond the inner edge of the casing; a fastening device consisting of the brackets If with bolts G therein, having ears a to pass into notch a between the cross-bar C and the molding C; a lever lI pivoted to the bottom of said bolt or bar; and a dog upon said lever so pivoted in relation to the pivotal point of the lever II that when the lever is moved next to the casing the pivot of the dog passes the dead-center and locks the same in position, as specified.

2. In a window-screen, the combination of cross-bars to eac-h end of the screen; suitable fasteners for one of the cross-bars and a tensionfastening for the opposite cross-bar, consisting of the bracket F with the bolt G therein; the lever H pivoted to said bolt and the dog I pvoted to said lever so situated that when the lever is pressed next to the easing the pivot of the dog passes the dead-center and locks the same in position, as specified.

3. In a window-screen, the combination of the screen B, bar D at one end with suitable means of attaching the same to the windowcasing; bar O at the opposite end; the molding C to clamp upon said bar and hold the screen between the two; a bolt G with an ear a to project between the bar O and the molding O'; suitable means of supporting the bolt on the casing inside the screen and means of adjusting the same, coaeting as specified.

4. In a Window-screen, the combination of the screen B; bar D, at one end with suitable means of attaching the same to the windoweasing; bar C, at the opposite end of said screen; the molding (y, to clamp upon said bar O, and hold the screen between the two; a bolt G, with an ear a, to project between the bar O, and the molding O', and pointed lug a', to engage the bar O, to prevent its rotating; and suitable means of supporting the bolt on the casing inside the screen and m cans of adjusting the same coaeting as specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
