UNITED STATES PATENT OFFIC ALBERT A. CARTER, OF PHILADELPHIA, PENNSYLVANIA.-

. IMPROVEMENT IN DOOR-SCREENS.

Specification forming part of Letters Patent No. 171,501, dated December 28, 1875 application filed August 24, 1875.

To all whom it may concern Be it known that I, ALBERT A. CARTER, of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Screens applicable to door and window openings, for excluding dust and insects from apartments while permitting ventilation through such openings; and I do hereby declare the following to be a suflicient-ly full, clear, and -exact description thereof to enable one skilled in the art to make and use the said invention.

Referring in so doing to the drawing annexed forming acomponent part of this specification, and letters of reference marked thereon, the same letters of reference apply to the same parts in the several figures.

The nature of my invention consists in the construction of a lip upon the upper edge of one door to cover the gap left by the overlapping of the frames holding one way from the casing or sash of the door or window.

Figure I shows a perspective elevation of one form of my invention; Figs. 2, 8, and 9, another form with parts detached to show their construction. Figs. 3, 4, 5, 6, and 7 show detached parts.

In the form shown in Fig. 1 two frames, B and 0, covered by netting are hung upon gudgeons or pivots 0 (see Fig. 6) at the outer side turning in horizontal stripes I and F, respectively, secured to the inner sill of the window and the molding next the sash. The strip F has a rabbet formed in it, and the strip I is fastened, by knee or angle piece Y, (shown in Fig. 5) to the inner molding next the window-sash. The frames B and 0 overlap each other in the center, and are held shut I by buttons marked N in Fig. 7. The buttons N are made of Z-shaped pieces of ductile metal perforated in the center for the screws on which they turn, and'with the wings or end bent up to afford an easy hold to turn them. The advantage of this form of button is that it is made with but very little waste of metal, and possesses sufficient elasticity to easily adapt itself to any changes in the thickness of the frames consequent upon moisture. The strips I and F are of sufficientbreadth to cover the thickness of both frames B and (l. The netting should be applied to the frames B and (J, so as to be in contact where the frames overlap.

In the forms shown in Figs. 2 and 9 the strips F and I are dispensed with, and the pivots are inserted directly into the windowsill below, and directly into angle-pieces y, applied to the inner side moldings of the window. The cap R (shown in Figs. 8 and 9) is secured to the upper edge of the frame 13, thus closing the space between the frame B and the sash. Metallic corner-pieces Z are inserted in kerfs cut through the mitered joints of the frames B and G, having their outer edges turned at right angles, as shown at d d in Fig. 2, and pins or screws passing through the parts of the frames B and O and the plates Z securely hold them. The same form of button N is applicable to hold this form of frames when closed, but is only used at the lower corners.

It will be seen on inspection that the motion of the sash of a window or door is not interfered with in openings to which this invention is applied by making the frames B and O to overlap. They can, without alteration, be applied to several-sized windows.

I am aware that overlapping sliding-screen frames, and also flush hinged frames, have been made and used; and these, therefore, I distinctly disclaim but What I do claim as my invention is-- The hinged overlapping screen-frames B and 0, combined with the cap R, as and for the purpose set forth.

ALBERT A. CARTER.
