INVENTOR A TTORNE Y8 citizen of the United States, residing PATENT o FFICE- LEOIPOLD SIMON, OF NEW YORK, N. Y.

' WIN DOW-SCREEN.

Application filed July 8,

To all whomit may concern: 7

Be it known that I, LEOPOLD SIMON, a at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window- Screens, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it a-ppertains to make and use the same.

, This invention relates to screens, and with respect to certain more specific features thereof, to adjustable and foldable light and air deflectors for window, porch and other building purposes.

- One of the objects of the invention is to provide a device of the above character which is capable of easy manipulation and is reliable and eflicient in operation.

A further object is to provide an improved screen adapted to control effectively the passage of light or air therethrough, as desired.

A. further object is to provide a weather shield of the above character which includes various features of structural and functional advantage.

Other objects and advantages will be in part obvious and in part noted hereinafter in connection with the following description of the accompanying drawings, which illustrate a typical embodiment of the invention.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the drawings,

Figure 1 represents a screen applied to a window opening;

Fig. 2 is a vertical sectional view thereof; Fig. 3 is a perspective view of a part;

Fig. 4 is a sectional detail .of a screen strip and clamp; f

Fig. 5 is an isometric view of a rod support; and

Fig. 6 is a sectional view of a locking device.

Referring more particularly to the draw- I ings, there is indicated a window casing having upright sides 1 and a transverse top 2, adjacent the corners of which are secured a pair of supporting brackets 3. A guidmg support 4, preferably in the form of a square rod or bar with round extremities,

is journaled to rotate freely in the brackets 3. A pair of screen-carrying devices are suspended from the rod 4 and are provided with a plurality of flexibleor collapsible screens or screen strips 5 extending therebetween. ably comprise transversely mounted angle members or cross pieces 6 and 7 arranged at opposite ends of the rod 4 and having a pair of vertically disposed parallel links ,8

pivotally connected to their ends. Additional cross members 9 are pivotally connected between the links of each frame for attaching the screensv and for insuring a parallel transverseand opposite simultaneous movement thereof when the rod 4 is rotated. The angle member 7 is preferably fixed to the bar 4 adjacent one side of the window casing 1, while the other angle member 6 is secured to a sleeve member or bracket 11 having a square bearing aperture for the rod 4. The sleeve 11 is thus mounted for translatory movement on the support 4 toward and away from the other frame for collapsing or extending the flexible screens therebetween. In order to render the sliding movement of the sleeve 11 free, ball bearings 12 are seated inthe sleeve to ride on the support.

Locking means are preferablyprovided to either extended or retracted position and thus maintain the screen strips taut or securely folded. As illustrated, the locking means forthe first men? tioned purpose comprises a latch 13, pivoted to one end ofa bell crank lever 14, which is in turn pivoted at 15 to the sleeve 11. A second and oppositely disposed bell crank lever 14 is also provided to operate the latch 13 for withdrawing the same from a -recess'18 in the left end of shaft, its position for holding the screen folded. A coil spring 16 located in a recess 16' in an offset lug of one bell crank lever works against a plunger 17 in said recess and bears on the sleeve Patented Aug. 2, 1921.-

These devices or frames prefer-' 11 to urge the latch 13 to locking position, I

that is, toward one of two recesses 18 provided in the support 4 adjacent its ends. An operating cord 19 is secured to the lever 14 at 20 and runs in a pulley 21, whereby the erablyadjacent ever, being attached to the free end of the bell crank lever 14 and runnln'g over a pu 1' ley 23, so that, on manipulation of the said cord, the latch 13 is withdrawn from looking position and the translatable frame then moved.

A foldin longitudina ly device or brace 24 is provided their lower ends or other the support 4, for rigidly spacing the frames when separated. In practice, this brace comprises a loosely articulated member, as two arms pivoted at their ends to cross channel irons connecting point remote from 1 the paral-lel' linlfsbf the screen frames and b extending down through apertures provided therefor in the screen strips, the same being knotted below a pivotal eye 29 on the brace adjacent the elbow thereof. A suitable pendent weight 30 is carried b the cord 27 for normally straightening t e latter. The offset forked arm of the sliding sleeve or bracket 11, above mentioned, is provided with a roller 31 which travels in a path to intercept the take-up cord 27 so that, as the translatable frame is pulled to the left, after the brace is manually broken, theroller 31 engages the cord and carries thesame there with to fold the brace and screen strips upwardly between the side frames.

There are also the sides of the window casing having studs or pivot members 33 which take into central openings in certain of the cross members 9 of the frames and afford a rigid axis in addition to the support 4 about which the screen strips may be rotatably adjusted by suitable means, such as a handle 34. To

' prevent displacement of the screen when the same is operated to folded position, a guide wire or rod 35 is provided at the lower end of the window and a pivoted central e e 36 on the lowest cross iron 9 serves to hoo the translatable screen thereto. The rod 35 thus holds the screen against swinging when extended or collapsed.

, In certain installations of the device, particularly with a screen of relatively great length, e. 9., more than six feet, it is desirable to provide an intermediate supporting means, brace or carrier for the rod or bar 4 to prevent the same from sagging.

For this purpose, a bracket 37 is secured to the top of the window casing 2, and is provided with a depending shaft 38 which has journaled thereon a plurality, in the present of. horizontally disposed and equidistantly spaced arms or levers 39, 40,

between the frames 8, 8, pref-- provided brackets 32 on' 41 and 42. These arms are curved downward slightly and one of the same is normally turned at right angles to the rod 4 to engage the lower surface thereof and support the same. As will be apparent, this arm extends in the path of movement of the translatable screen frame, but as said arms are free to rotate, the same will be turned through 90 by the right frame link 8 as the latter travels to the left. Accordingly, the adjacent arm 39 will move under and suport the rod 4 as the arm 42 leaves the same.

imilarly, reverse movement of the translatable frame, when extending the screen, rotates the arms in an opposite direction, thus allowing the sleeve 11 to travel to the right and returning the arm 42 beneath the rod 4. The bracket 37 is illustrated as provided with four arms since the screen is preferably divided into sections, when the same is rela tively long, and in such instances four or more screen frames and sliding sleeves may successively pass and rotate'the arms 39, 42.

As illustrated in Figs. 2 and 3, the pivotally movable screen strips 5 are superposed in parallel lanes and each comprises a flat longitudina body portion 5 and longitudinal or axially disposed edge portions 5 and 5 reversely inclined with respect to the body portion and transversely of the axes of rotation. The screens are. mounted substantially equidistantly apart with axes in vertical alinement so that, as the same are turned to approach an approximately vertical plane, the down-turned edge 5 of each effected so that light and air may be subi stantially excluded from passage therethrough. Furthermore, the contour of the screen units serves to materially prevent the entrance of rain or snow through the screen, even when the same are adjusted to admit a free current of air.

In order that the screen units may be readily assembled or withdrawn from the other parts of the device when desired, end members, or clamps 43 are provided therefor, consisting of flexible metal strips reflexed over the ends of the screen strips and then doubled to provide curved or exteriorly V-shaped members laterally insertible in the holders 9, which also constitute cross members for the links 8 and are bent to provide longitudinally extending transversely curved open channels 9 having a wall or web 9" lying within the channel and projecting partway thereacross to lie in the recess, or concavity, in the 'U-shaped member. The screen clamps may thus be readily telescoped laterally to nest within the holders, the clamps bein preferably longer than the holders, so that the ends of the former ex- 2. After assembly these projecting ends are inclined or offset, as indicated, for the purpose of inclining the edges of the screen member 5, as above set forth, and also for locking the screen members against unintentional displacement.

While the operation of the device will be largely obviousfrom the foregoing description of thestructure, the same may be briefly set forth as follows: Assuming the screen to be in extended operative position, as illustrated in Fig. 1, the same may be folded or collapsed by manual release of the brace lock 26 and operation of the cord 22. The latter serves to automatically release the sleeve latch 13 and thereafter slide the sleeve 11 and the right frame members to the left,

thereby collapsing the screens.' When the bracket 11 reaches mid-position on the support 4, the roller 31 picks up the brace cord 27 and the latter, with the brace 24, takes up the slack in the screen strips thus successively looping the strips and renders the whole device compact and firm when folded. Thereafter, manipulation of the opposite cord 19 releases latch 13 and moves the translatable frame to the right. whereupon the sleeve 11 will be locked in extended position and the brace simultaneously stralghtened to rigidly longitudinally space the lower ends of the links 8, In the operation of extending the screen, the right frame will fit over the pivotal stud- 33 provided onthe right window casing. It will be understood that the arms 39, 40, 41, and. 42 operate in the manner above described to support the rod 4 and thereby prevent sagging or bendto provideone or more metal stripss44 secured longitudinally to certain of the links 8.. These strips serve to close any gap between the sides of the screen and the-window frame, and also to reinforce the links. Furthermore, when a plurality of the screens are provided to operate in opposite directions on a single su port 4, the metal strips 44 overlap when t e sereens are extended and thereby prevent any objectionable openings between the screens when closed.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention couldbe made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not me limiting sense.

It is also to be understood that the langua e used in the following claims in ten ed to cover all of the generic and specific features of .the invention herein described, and all statements of the scope of the in vention which, as a matter of language, mi ht be said to fall therebetween.
