WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 553,006, dated January 14, 1896.

Application filed August 22,1896. Serial No- 560,l37. (No modem To a whom it may concern:

Be it known that 1, JOHN J. LINCKS, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain newand useful Improvements in \Vindow-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 appcrtains to make and use the same.

My invention relates to improvements in that class of window-screens which are designed to be raised and lowered independently of the window-sashes, and its novelty and advantages will be fully understood from the following description and claim, when taken in connection with the annexed drawings, in which Figure l is a front elevation, partly in section, of a window equipped with my im provements. Fig. 2 is a vertical transverse section of the same, and Figs. 3 and 4. are detail sections taken in the planes indicated by the lines a: a; and 3 g respectively of Fig. 1.

In the said. drawings similar letters designate corresponding parts in all of the views, referring to which- A indicates a window frame provided with the usual sill a. and beads l).

B B indicate the window-sashes, which may be of the usual sliding pattern, and O indicates the spring-actuated roller of my improved screen. This roller C may be constructed in the ordinary manner, and it is arranged in a casing D, mounted upon the win dow-sill a, and has the trunnions c at its ends mounted in the metallic brackets E, as better illustrated in Fig. 3 of the drawings. The brackets E are respectively cast or otherwise formed in one piece, and they comprise the body portions 6?, in which the bearings for the roller are formed and which rest against the inner sides of the beads b and the angularlydisposed branches e, which rest against and are connected by screws or the like to the faces of the side stiles of the frame A, as shown, so as to secure the brackets in position.

F indicates vertical grooved strips which are connected to the beads b and extend the full height of the window-opening, as shown in Fig. 1, and Gr indicates the screen proper of myimprovements, which is formed of flexible wire or other suitable material. This screen G is of such a width that its side edges will extend well into the grooves of the strips F in order to prevent insects from passing between such edges and the window-casing, and it is of such a length that when entirely unwound from the roller 0, to which its lower end is suitably connected, it will extend from the bottom to the top of the window-casing. At its upper end the screen G is connected to a transverse strip ll, which has its ends arranged and adapted to move in the grooves of strips F. To this strip His connected one end of a screen-hoisting cord I, which passes through a pulley J, secured at the upper end of the window-frame, and may be provided at its free end with a ring or the like.

The pulley J is of the toggle-wheel type and is adapted to hold a cord against movement, when the same is properly adjusted with respect to the wheel of the pulley, in the ordinary well-known manner.

In using my improved screen when the sash B is raised, as shown, and it is desired to screen the opening beneath the same, it is simply necessary for the operator to draw upon the cord 1, so as to raise the screen to the position shown in Fig. 1. The screen may be held in this position by properly adjusting the cord so that the pulley J will hold it against movement.

hen the sash B is raised and the sash B lowered to afford openings at the top and bottom of the window-frame and it is desired to screen such openings so as to prevent the en trance of insects into a room, it is simply necessary for the operator to raise the screen through the medium of the cord I to the top of the window-frame and then secure the cord by the pulley J in the manner before described.

\Vhen the window-sash is closed, as in winter, the screen G is wound upon the roller 0 in casing D, the said roller being adapted to automatically wind the screen when released, as before described.

It will be appreciated from the foregoing that by reason of my improvements flies, mosquitoes, and other insects may be effectually excluded from an apartment; and it will be observed that with all of its advantages my improved screen is very cheap and simple and may be connected with any ordinary windowframe Without the employment of skilled labor, which is a desideratum.

I am Well aware that a check-pulley used in conjunction with a curtain-cord is old, and I therefore make no claim to the same; but

\Vhat I claim,and desire to secure by Letters Patent, is

The herein described Window-screen construction, consisting essentially of the following elements in combination, viz: the Window frame, the vertically movable sashes B, B, arranged therein, the vertical grooved strips F, connected to the inside of the side stiles of the frame, the brackets E, each formed in one piece and respectively consisting of the body portion having a bearing in its inner side and the branch 6, disposed at right angles to the body portion. at an intermediate point in the length thereof; said branches e, being connected to the faces of the side stiles, the spring actuated roller C, having trunnions mounted in bearings in the body portions of brackets E, the casing D, arranged on and connected to the frame sill and inclosing the roller C. the screen connected at one end to the roller 0, and having the transverse strip H, at its opposite end and also having its side edges and the ends of the strip I-I, arranged and adapted to move in the grooves of strips F. the pulley J, connected to the upper end of the Window frame and the cord connected at one end to the end strip of the screen and passed through the pulley J the said pulley being adapted to hold the cord and screen in various adjusted positions, substantially as and for the purpose set forth.

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