3 Claims (01. 160-369) This invention relates to improvements in insect screens and the mounting means therefor in conventional window structures.

It is an object of the present invention to form an insect screen having a frame of extruded metal and guide means for the support of the frame in a conventional window opening having resilient means in both the guide and the frame to permit shifting of the frame to uncover the opening, while the frame is maintained in various degrees of adjustment under the influence of V the resilient means.

A further object of the invention resides in the provision of insect screens having a rigid frame of extruded metal adapted to be shifted easily and conveniently to open or closed position and which will remain in the various positions of shifting and metallic spring projected guide devices arranged in the window opening for the sliding reception of the frames, such guides formed of a fixed channel member and an overriding channelmember shiftable laterally thereon under the influence of a plurality of springs whereby the fixed and overriding members provide an equalizing guide for the screen frames in those windows having irregular side walls.

It has been found extremely desirable to provide in the conventional double hung windows, screen devices capable of being shifted to an uncovering position to permit an exit through the opening for the exterior cleaning of windows, will always remain in any position of adjustment, "may he used either as single screens oras double overlapping screens, readily adjust' themselves to overcome irregularities in the window, are light I in weight, strong, durable, cheap to manufacture and are highly convenient in use.

Qther objects and advantages of the invention ,will be readily apparent during the course of the follOWlIlg description, reference being had to the accompanying drawings, wherein has been illustrated a preferred form thereof.

In the drawings:

Figure 1 is an outer side elevation of a conventional window, showing the invention in use,

Figure 2 is a vertical section, taken on line 2-2 of Figure 1, v

Figure 3 is a fragmentary horizontal section, taken on line 33 of Figure 1,

Figure 4 is a fragmentary vertical section taken on line 4-4 of Figure 3, Y 1

Figure 5 is a fragmentary perspective view of a corner of one frame member and,

Figure 6 is a perspective view of a friction Spring device. r

Like numerals are employed to designate like parts throughout the several figures of the drawings.

Referring specifically to the drawings, the numeral 5 designates a conventional window of the doubl hung type, having side rails 6 and top header 1 and sill 8. Window sash 9 are mounted in the usual manner to be'raised and lowered in the guides ill, formed by the usual strips ll.

Rig idly secured to the inner faces of the side rails 6, in the space normally provided for Wood frame screens, are channel members E2, of a height substantially that of the window opening. The channels If! are held in fixed position against shifting, by screws is. The screws l3 further serve as mounting means for generally V- shaped leaf springs M. The terminal ends of the springs are'curved, at 55. It is contemplated that any suitable number ofthe springs I l may be employed in each channel, although it has been found that a spring adjacent the upper and lower end of the channel and one in the center is sufficient for normal use. Overriding the channel l2, is a channel member it, having an inside width suflicient to permit a sliding fit over the channel l2. The channel it has its outer side wall extended at ll, for its full length and parallel ribs l8, forming identical guide grooves l5, likewise extend for the full length of the channel. The grooves 59 are adapted to slidably receive upper and lower screen frames 26 and 2!, to be described. As before pointed out, the channels l6 slidably override the channels l2 and are 'normally urged outwardly by the engagement of the curved ends I 5 of the springs i 4, against the inner wall of the channel It, thus presenting a resilient mounting for the screen frames 26 and 2! throughout the sliding of the frames. The resiliency of the mounting forv the channels it adequately compensates for slight irregularities that might be present in the window frame, providing at all times parallel guides upon opposite sides of the window.

The upper screen frame 2c is formed generally rectangular and comprises parallel sides rails and parallel upper and lower rails 22 and 23. The rails 22 and 23 are preferably extruded light weight metal, such as aluminum and the several rails are mitered at their corners, as at 24. The several railsare provided with a generally rectangular shaped channel 25 throughout their length and the channel 25 communicates with the marginal edge of the frame through the medium of "a relatively narrow slot 25, having its edges ifil l lied- The rails are further provided with an undercut channel 2'1, for the reception of the marginal edge of the screen cloth 28. The edge of the screen cloth is held against displacement from the channel 2?, by a compressible bead 29 that is forced into the channel. The frame is rigidly held in assembled position at the mitered corners, by angle bars 35, crimped or otherwise held in the channel 25 of adjoining frame sections, as clearly shown in Figure 4. The slot of the upper rail 23 may carry a strip therein that projects slightly above the rail to overcome any slight irregularity in the header of the window. This strip is indicated at 3|, in Figure 2.

The lower screen frame 2| includes extruded side rails 32, parallel with each other and upper and lower extruded rails 33 and 34. The rails 32 and 33 are identical in shape and are provided with rectangular channels 35, communicating with the marginal edge of the frame, through the medium of the relatively narrow slot 36. Undercut channels 37 are provided for the reception of the marginal edges of the screen cloth 38. The frame members 32 and 33 are identical to the frame members 22 and 23. The lower frame member 34 is formed relatively wider than the frame members 32 and likewise is provided with the channel 35 and the undercut channel 31. An identical slot 36 extends from the channel 35 to the marginal edge of the member 34. A strip 39 is positioned in the slot 36 of the member 34 for engagement with the sill of the window as an equalizer to overcome any irregularities of the sill. The frame 2| is assembled in a manner identical with that of the frame 20, by mitering the corners and rigidly binding them together by the angle bars 30. The frame member 34 is provided with a horizontal lip 4|], as a means to facilitate the raising and lowering of the frame. Any suitable locking means, not shown, may be employed for retaining the screen frames in closure position against unauthorized movement.

As clearly shown, the upper and lower frames 20 and 2| are adapted to partake of vertical sliding movement in the guide grooves !9 of the channel I6, with the frame 20 being arranged in the outer groove, while the frame 2| is arranged in the inner groove and, in closed position, the

lower rail 23 and the upper rail 33 are in parallel alignment, with the rails spaced a distance equal to the thickness of the ribs l8. The frames 28 and 2| are independently shiftable in their respective grooves l9.

As before pointed out, the springs l4 exert a continuous outward pressure upon the channels [6, which pressure would, under certain favorable conditions, be suflicient to hold the frames 20 and 2| against accidental sliding in the grooves. However, to insure against such accidental sliding, due to jarring or excess weight in larger screens, it has been found desirable to provide additional friction means that will maintain the screen frames in any position of adjustment. For this purpose, a plurality of semi-circular leaf springs 4|, having angularly disposed terminal ends 42 of a width that permit of a snug engagement in the channels 25 and 35 of the side rails 22 and 32, and are arranged at predetermined points in the side rails 2 2 and 32, with the semicircular leaf projecting through the slots 26 and 36 for frictional engagement with the bottom walls of the grooves l9. The terminal ends 42 are further bent at an abrupt angle, as at 43, so that, when the spring 4| is flexed inwardly, the ends 42 will-rock upon the bottom of the channels 25 and 35, causing the ends 43 to bite against the opposite wall of the channels, thus preventing any tendency of the springs 4| to slip in the channels when the screen frames are moved to open or closed position.

In the use of the device, the channel members l2, having first been installed, with their springs l4, the channels are then positioned thereover. Limit screws 44 are then engaged in suitable openings formed in the side walls of the channels I6 and freely ride in horizontal slots 45, formed in the side Walls of the channels l2. Thus, the channels l2 and M; are yieldably held in mounted position against the sides of the window frame against displacement. The frames 29 and 2| are then mounted in their respective grooves l9 by first engaging one edge of the frame in a groove at one side of the window and, by a sidewise pressure, compressing the springs 4, provides suflicient clearance for the opposite side of the frame to engag in its groove. This method of engagement is identical with both frames and the removal of the frames is done in a similar manner. The combined yieldable pressure of the springs l4 and 4| assure that the screen frames will remain in any position of adjustment, providing an easy vertical shifting of the frames. Further, the yieldable nature of the channels l2 and i6 assures of a perfectly aligned guide for the frames, regardless of the irregularities of the window frame.

While the structure hereinbefore described was designed primarily for insect screens, it will be obvious, that by slight modifications in the frames, a sheet of glass may be substituted for the screen wire, thus providing a very desirable storm window.

It will be apparent from the foregoing, that a very simple and highly efficient window screen has been provided. The parts are few and simple, are easily extruded for economy in manufacture, are rigidly held in assembled relation against twisting by the corner angles, is neat in appearance, readily lends itself to installations upon various types of windows, permits ready access to the outer sides of the window and is simpl and easily installed or removed.

It is to be understood, that the invention is not limited to the precise arrangement shown, but that it includes within its purview, whatever changes fairly come within either the terms or the spirit of the appended claims.
