zc/ 54 V l ATTORNEY Patented Apr. 2, 1935 UNITED STATES PATENT OFFICE This invention relates to devices such as rolling window screens.

, One object of the invention is to provide a device of the character described having improved means for mounting a window screen roller so as to facilitate repair or replacement with particular reference to the screen, and to permit removal of the screen and roller from the window casement in a highly simplified manner, ,0 if such removal be necessary.

Another object of the invention is the provision of a device of the nature set forth having improved means associated with a screen movable into a window casement or frame, so as to render [5 the latter weatherproof as against entry of rain thereinto. v i

A further object of the invention is to furnish a device of the nature set forth having relatively few and simple parts, and which is inexpensive to manufacture, adapted to be embodied with widely different types of windows, which is conveniently operated by a person with little or no mechanical skill, which is neat in appearance, compact in arrangement, durable, reliable and eificient in use. 1

Other objects and advantages of the invention v will become. apparent as the specification proceeds;

With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

In the-drawing: Y j Figure Us a view in front elevation of a device embodying the invention, with the sashes partly 40 open;

Fig'. 2 is an enlarged fragmentary view taken on line 2-2 of Fig. l.

Fig. 3 is a fragmentary sectional view taken on line 3-3 ofFig. 2. Fig.4 is an enlarged sectional view of the weather proofing element, showing a slightly modified arrangement.

sectional In devices of this character heretofore known, it has been difficult to remove the screen and 50 roller when desired, and hasrequired considerablemechanical skill to accomplish such removal.

By my invention this can be done in a particularly simplified manner by anyone.

The advantages'of the invention as here out- 55 lined are best realized'when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.

Referring in detail to the drawing, Ill denotes a device embodying the invention. The same may include a window frame I I which may be a standard stock or special window frame of varying size. construction and arrangement. Said frame may include the head and sill portions l2, l3, respectively, and the side uprights M. The window frame may be provided with suitable means for guiding sashes, such as, for example, the respective upper and lower sashes l5 and I6, and the guide means may be in the nature of the channels I! and I! for the respective sashes, these channels being separated by the parting strip IS. The sash [5 may include the usual head rail 20, and the sash Ii may have a sill rail 2|, the screens being connected to these rails as hereinafter described. It will be understood that, the illustration of a window as herein shown is conventional, but that the invention is not limited thereto, and other window constructions may also be used.

In'general, it may be noted that the window frame structure may bear any suitable relation to the thickness of the wall, and may bearranged in any manner well, known in the art. 'I'he,win-.

.dow'frame is modified by this invention in that. it includes upper and lower pockets, chambers or movable compartments, in the head and sill {I 2, I3, and openings or slotsbeingflprovided inthe,

head and sill in communication with said com:

'partments for movement of screens from said compartments along the. window frame, as by connection with the individual upper and lower sashes, whereby a screen and its respective sashv is movable as annit. Since the structure for the head of the frame is merely the inverted form of that used at the sill of the frame, only the latter is shown and described in detail herein;

The sill portion of the window frame may include a longitudinal pocketor chamber'ZIextending therealong, for example, in a horizontal direction. If desired, this chamber may be formed wholly in the wall 2: into which the window frame is set,'or partly in said wall and partly inthe frame, or wholly in the frame. As

the term window frame is used herein, it may,

comprehend any necessary portion of the wall 23, according tothe construction used, and the term window is to be understood as including any desired closure or ventilation control.

The chamber 22 may be closed on top by the sill element 24 which may have an opening or slot 25 extending longitudinally thereof and arranged to communicate with the chamber and to aline with the proper cooperating sash, in this case, the lower sash l3.

Movably or slidably mounted in the chamber 22 is a supporting means 26. The latter may, for instance, be in the nature of a drawer which may have one or more walls, such as a bottom wall 21 and a front wall 23. The drawer is thus of substantially skeletonized construction so as to be light in weight and inexpensive in construction. This drawer is movable inwardly, that is, toward the left, through an opening 29 that may be formed in the front face element 33 ofthe window frame. If desired, the drawer may be wholly removable from said chamber, but in the closed position shown, the wall 23 of the drawer may lie substantially in the plane ofthe frame element 30 so as to afford a finished appearance.

-' The drawer may be locked shut in any suitable manner as by easily removable screws 3|, and may be fitted 'in'the frame along angular lines 29a. 1

Mounted in the drawer 23 is a feeding means 32 for flexible or pliable element, that may consist of a suitable fabric, or sheet material, as, for example, a screw 33. Said feeding means may be in the nature of a conventional window shade roller 34 having the usual internal coil spring (not shown) for tending to cause the roller to wind up the screen thereon. The roller differs merely in that the usual ratchet and dogs for stopping the roller in a desired position are omitted. Said roller may be removably mounted in a well known manner, as by axial-end pins 35 journaled in brackets such as 33 secured to the drawer bottom 21 as at 31. At least one of the brackets may have an angular slotted bearing 38 for removably receiving its coacting pin ll.

It will be understood that the screen feeding or control means 32 is disposed in suitable operative juxtaposition to the slot 15. Ifthe depth of thewindow frame is greater than shown, the drawer bottom 21 may be correspondingly increased in size, as will be obvious.

The screen 33 may extend the full width of the sash and the slot 25 may be correspondingly long. Free edges of the screen may be reenforced in a suitable manner by closer weaving, or by suitable tapes or strips such as 39 and 40, the former of which may be secured along the side edges of the screen, and the latter along the free end thereof. These strips may consist of fabric, metal, or composition material.

The screen 33 is preferably detachably connected to the sash, at an adjacent rail thereof as by providing the sill rail 2| of the sash IS with a rabbet, groove or undercut ll in which the connection is made. Various types of connecting means may be used, and for illustrative purposes, I show aplurality of headed pins or screws 42 secured to the sash, the screen having keyhole slot openings 43 in the reenforcement 40, for detachably receiving and engaging over said screws. As thus arranged there is no projection on the sash.

To prevent the entrance of rain through the slot 25, a suitable Weatherstripp or deflector is provided adapted to slidingly engage the screen on the outer face thereof, in such manner as not to interfere with the up and down movement thereof. Preferably also, the deflector is movable, so that should the screen be disconnected from the sash and removed from the slotpassage 25, the deflector will-be movable downward to cover and close the slot. Said deflector may be omitted at the head of the window frame.

The deflector 44 may include a plate having a thin sheet of pliable fabric or rubber 46 extended thereover and having along its longitudinal edges oppositely formed beads 41, 38 within which the sheet is clamped. The lower bead 48 may have a rod-l9 extending therethrough and suitably iournaled in the uprights ll of the window frame. The upper bead section I! may have a relatively large radius for wiping contact with the screen. Said deflector 44 may be mounted in a recess 50 of the frame element 24 as shown in Fig. 2, or on the upper surface of the sill as shown in Fig. 4. In the latter case, the sash may merely come to rest on the deflector, in the closed position. A weak leaf or wire spring Il may be slidably engaged over the lower bead structure as at 52 and may rest on the bottom of the rabbet with an end 53 of the spring bearing upward on the deflector to tend to elevate the same. The springs may be provided at opposite ends of the deflector.

In operation, when a sash is raised or lowered the screen connected thereto is correspondingly moved and winds or unwinds automatically on its roller. Thus the screen is exposed only to the extent that the window is open. In case it rains, the water running down the screen is deflected by the means 44 so as not to enter the window frame. If the lower sash is closed, the means 44 is depressed into the recess I0, so that the upperbead section moves the screen laterally and substantially closes the slot opening 25. When the sash is again raised, the means 44 is frictlonally elevated, with the aid of spring 5|. The weight of the means 44 may normally be relied upon to hold the same in suitable contact with the screen. The entire arrangement is such that binding or jamming with the screen is avoided. If a; person desires, he may readily detach the screen from the window, at the inner face thereof. If the screen and roller are to be removed for replacement or repair, it is merely necessary to remove the drawer screws, and withdraw the screws, after which the roller may be disengaged from its brackets in the usual manner. It. will be noted that the tension of the roller spring will affect the counterbalanced condition of the sash, and hence any suitable sash locks such as 54 may be provided. to hold the sash in predetermined position.

It will be appreciated that various changes and modifications may be made in the device as shown in the drawing, and that the same is submitted in an illustrative and not in a limiting sense, the scope of the invention being defined in the following claims.
