WINDOW-SCREEN.

Patented Nov. 2, 1909.

the drawings by letter, A designates the sill of a window, B the jamb and C the lintel, all of the usual construction. Mounted between the jambs of the Window are the upper and lower sashes, designated respectively by letters D and D, between which is the usual parting strip (Z. F astened to the faces of the window jambs are the blind strips E to each of which are fastened the pins or studs F, the shank portion of each of which forms, 5 preferably, a bearing surface fora hollow roller F, thereby reducing the friction intermediate the pins or studs and the walls of the guide grooves G, formed in the vertical bars H of the screen H, to a minimum. Each of said bars H is rabbeted upon one face thereof and adapted to receive the guide strips I which, when fitted in place, have their outer faces flush with the faces of the screen.

Each of the bars H of the screen frame is recessed or slotted as at J, .afiording means whereby the screen may be swung outward when the slot comes opposite one of the studs or pins F. The bottom wall of each groove G formed in the screen bars H is recessed as at L, and L designates a spring fastened at one end within said recess, and having a curved portion projecting in the manner shown so as to contact with the end of one of the studs or pins F with suflicient frictional force, when the screen is at. its highest limit, to hold the same in such adjusted position. Projecting from the lintel .of the window is a stud or pin N which is adapted, when the screen is at its highest position, to engage a socket N formed in the upper marginal edge of the screen frame. Projecting also from the under edge of the lintel is a screen retaining strip 0 which is positioned outside the screen and serves as an additional means for holding the upper end of the screen from moving outward when raised to its highest position, said strip 0 forming, when the screen is raised and engaging the same, a lap joint, either one of these means being utilized for preventing the screen from moving outward.

Fastened'to the upper end of the screen is a plate Q, which overhangs and forms a closure to the groove G which is formed in the edge of the screen bar and adapted to rest upon the roller F mounted upon the upper of the studs or pins. F, it being understood that each vertical edge of thescreen In Fig. 5 of the drawings, I have shown a slight modification of the form of rabbet strip in which, instead of rabbeting thescreen frame entirely through the wall of the'slot or groove therein, I form a recess, preferably with a concaved wall as shown and adapted to receive a guide or rabbet strip R having a convexed edge conforming to the concaved wall of the rabbeted portion and with its other two edges flush with the face and edge of the screen frame.

In Fig. 6 of the drawings, I have shown a modified form of removing the screen from the window jambs, consistin of forming a slot T on the outside of t e screen, thus affording means whereby the screen may be removed by swinging the same out- .ward and in such position giving the same a downward movement, as will be readily understood. In order to hold the screen locked, in its lowest position, any suitable fastening means S may be applied thereto and adapted to engage the sill of the win- In operation, when it is desired to adjust the screen in place, the slots J are brought opposite one of the pins F, allowing the screen to be inserted intermediate the blind stops. The anti-friction rollers mounted upon the pins will serve as guides to the slots or grooves to allow the screen to be raised and lowered as an ordinary vertically movable window sash. \Vhen it is desired to hold the screen at its highest position, it is done by the spring L engaging frictionally the head or ends of the studs or pins F while the upper end of the screen will be held from lateral movement by means of the stud or pin N engaging the socket N or the retaining strip 0, either one or both of which may be employed. When it is desired to remove the screen from the window, it may be done by lowering the screen so that one of the slots or recesses J will come opposite the stud F, allowing the screen to be pushed outward. When the screen is adjusted to swing, the plates Q will rest upon the upper of the studs or rollers F forming bearing surfaces.

By'the provision of the rollers engaging thegrooves in the screen frame, the usual tongues are dispensed with and the friction between the screen and the guide rollers will be reduced to a minimum.

What I claim to be new is 1. In combination with a window frame, a screen frame having grooves in its'outer vertical edges, said grooves being closed at their upper ends, projections from the j amb ofthe window frame extending into said grooves and serving as guides to the frame, one wall of each of said grooves being recessed for allowing the screen to swing laterally.

2. In combination with a window frame, a screen frame having grooves in the outer vertical edges, said grooves having closures at their upper ends, guide studs projecting from the jamb of the window frame into said grooves and adapted to contact with said closures to form bearings upon which the screen is allowed to swing.
