WILLIAM WALLACE MOORE, OF PHILADELPHIA, PENNSYLVANIA.

WINDOW OR DOOR SCREEN.

SPECIFICATION forming partrof Letters Patent No. 439,751, dated November 4, 1890.

'Application filed April 25, 1887. Serial No. 236,084. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WALLACE MOORE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Vindow or Door Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in window and door screens; and it consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in front elevation of a window having my invention applied thereto. Fig. 2 is a view in section on line A B of same. Figs. 3 and 5 are views in elevation showing the screen applied to a door. Fig. 4 is a View on line N and O of Fig.3. Fig. 6 is a view on line R S of Fig. 5. Fig. 7 is an end view in elevation of the segment, showing also the rock-shaft and lower end of the screen. Fig. 8 is a face View in elevation of same. Fig. 9 is a view in section through the segment. Fig. 10 is a view of a portion of the rock-shaft. Fig. 11 is a plan view of the parts shown in Fig. 8. Fig. 12 is a view in end elevation of the tube or casing. Fig. 13 is a view of one of the end caps of the casing. Fig. 14 is a View in longitudinal section of the casing. Fig. 15 is a view in transverse section of same. Fig. 16 is a view of the lower end of the screen. Fig. 17 is a view in section of same. Fig. 18 is a view of the binding or covering for the lower end of the screen.

When the device is employed on windows, as shown in Figs. 1 and 2, I prefer to attach a screen to the frame above the upper sash and one to the frame below the lower sash, so that when either sash is moved from its normal closed position the space formed by the movement of the sash will be covered by the screen; but insteadof attaching the screen-casing to the frames they can be attached to the sashes or doors. IVith either arrangement of parts when used on windows I employ two tubes or casings, each inclosing a screen c, having at one end a bar n, provided with a series of holes as, into which the hooks c enter. Inlthe constructions disclosed in Figs. 1, 2, 3, and 4 the casing or tubes e are secured, respectively, to the frame at the upper end thereof and within a recess formed in the sill, and the upper sash carries at its upper end a shaft havingva series of hooks for engaging the free end of the upper screen, and thelower sash carries at its lower end a shaft having a series of hooks for engaging the free end of the lower screen. The screens a are each attached to a roller d, located within its respective tube or casing e, and each tube is provided longitudinally with a slot f for the passage` of its screen. Within each tube or casingis a spring g, one end of which is attached to the tube or casing and the other end to the roller d, upon which the screen is wound. The upper casing is secured to the frame by the screws 7c, and the lower casing to the under side of sill r, or other convenient parts, by screws 7e. The hooks c, before referred to, are secured to the rock-shafts Z, each carrying an arm or lever m, by which it is rocked. The shafts Z, carrying the hooks o, are supported in bearings p and rocked by the lever or handle m, which, if desired, may be retained in place by the notched segment or clutch o. (Shown in Figs. 7, S, and 9.) When the screen is disconnected, the arm m will rest in the upper notch o', as shown in dotted lines in Fig. 9, and when connected to the screw will rest in the lower notch o2, as shown in full lines in said figure. The segments o are shown only in connection with the upper sash; but they can be employed, if desired, on the lower sash. The ends of the rollers d are supported by perforated caps V, secured on the ends of the slotted casing. (See Fig. 14.) The object of the spring is to wind the screen on its roller as the sash is moved toward its roller, and the tension should be so adjusted as to completely wind up the entire screen when the latter is released. This adjustment can be secured by a key or crank, which can be placed on the squared end of the roller d.

In the event that the device is to be attached to old window-frames the slotted tubes may be arranged in front of the casing or on the ICO which latter, when the. lower sash is down,

rests within the recess in the lower edge of the sash.

The springs which actuate the roller in one direction are separated from the screen by the disk w. (Shown clearlyin Fig. 14.) The spring g, being wound on the roller in the opposite direction from the way in which the screen a is Wound, will be rolled or wound up when the screen is unwound, and vice versa. 'If desired, the slotted casing may be attached to the movable sash or door and the rock-shaft carrying the hooks to the sill or frame, as.

shown in Figs. 3 and 4 butI prefer the method previously described. When two doors are in use, the slotted casing may be attached to one and the rockshaft to the other door. Where swinging or sliding doors are in use, the slotted casing'may be attached tovor let into the lintel and the rock-shaft let into the floor or sill, as shown in Figs. 5 and 6, the screen being drawn down by hand and hooks.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isv 1. The combination, with a spring-roller anda screen wound thereon, the latter being provided at its free end with a series of holes, of a rock-shaft having a series of hooks arranged to enter said holes and an arm securedto said shaft for actuating same, substantially as set forth.

2. The combination, with a spring-roller, a screen thereon, and a bar secured to the free end of the screen and provided with a series of holes, of a rock-shaft having a series of hooks adapted to enter said holes, and an arm, and a segment for engaging the arm and locking the shaft against movement.

The combination, with a casing attached to a sill, a spring-roller located within said casing, and a screen wound on said roller, of a sash having a groove in its lower edge and a shaft located within said groove and provided with hooks for engaging the screen, substantially as set forth.

4. The con1bination,with asash and a frame, of a spring-actuated roller carrying a screen attached to one of said parts and a rock-shaft carrying hooks carried by the other part for engaging the free end of the screen.

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

WILLIAM WALLACE MOORE.
