SCREEN.

'ratentea May 22, 1906.

Application filed August 28, 1905. Serial No. 276,046.

To all whom t may concern.-

Be it known that I, WILLIAM OBYRNE, a citizen of the United States, and a resident of `Port Chester, in the county of Westchester and State of New York, have invented new and useful Improvements in Screens, of which the following is a full, clear, and exact description.

This invention relates to screens, such as are placed in the windows of buildings to prevent the entrance of insects. More speciiically, the invention relates to that type of screen which is attached to the casement and to the sash and which extends itself automatically, as it were, to lill the open space at the window.

The object of theinvention is to provide an improved arrangement for attaching such screens to the sash and'to the easement, to the end that the screens may be removed or replaced with the greatest facility. i

Reference is to be had to the accompanying drawings, forming a part of this specifica tion, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective showing a window provided with my screens. Fig. 2 is a vertical section of the window-easement and taken substantially in the plane of the upper sash in order to illustratethe manner of attaching the upper screen. In this View certain parts are broken away and shown in sec tion, Fig. 3 is a vertical section similar to Fig. 2, but representing the corresponding arrangement for the lower sash. In this view certain parts are broken away and shown. in section. Fig. 4 is a fragmentary perspective showing a portion of the upper corner of an upper sash and illustrating a leaf-spring or plate, which is representedas thrown back and in the position which 1t assumes when A the batten carrying the screen is being fixed in position. Fig. 5 is a view similar to Fig. 4, but representing the spring in its normal position. Fig. 6 is a perspective of the lower corner of the lower sash and showing the leafspring or plate which retains the roller of the lower screen. Fig. v7 is a fragmentary perspective further illustratingvthe manner in which the lower screen is attached to the lower sash, and Fi 8 is a cross *section taken at the end of one o? the rollers which carry the screens.

Referring more particularly to the parts, 1 represents the window-easement, comprising side members 2, a sill 3, and a lintel 4. The sides 2 are provided with the usual longitudinally-disposed partingstrips 5, which are disposed between the sashes 6 and 7 and afford means for guidi-ng the same vertically in the usual manner.

Referring especially to Fig. 2, the manner of attaching the upper screen 8 in position will now be described. The body of this screen isformed of a flexible fabric of mesh, such as stout mosquito-bar, the same being wrapped upon a roll 9. In order to receive this roll neatly, the lower face of the lintel 4 is preferably formed with a longitudinal recess 10, in which the roll is placed,- as indicated. At one extremity of the recess l0 and at one side of the easement a pivot-stud 11 is rigidly attached, which constitutes a center or axis of rotation for the adjacent end of the roller in a well-understood manner.

'Opposite this point a recess 12 is formed in the upper extremity of the opposite side member, and at this recess there is attached a resilient plate or leaf-spring 13. The lower extremity of this plate is attached rigidly to the inner face of the side member 2, and the plate projects longitudinally of the side member, as shown, the upper extremity of the plate being received in the aforesaid recess 10. This plate 13 is provided on its inner face with a pair of gudgeons i4, the purpose of which will appear more fully from an inspection of Fig. 8. Referring to this latter ligure, I provide the body-of the roller 9 with the usual recess 15 at its extremity, in which recess there is centrally and rotatably mounted a button 16. This button is connected by a spiral coil-spring 17 with the roller. The button is provided with a pair of openings 18, which may receive the aforesaid gudgeons. From this arrangement when the gudgeons are in engagement with the openings they prevent the rotation of the button, so that as the roller is rotatedthe spring will be wound up. The recess 12 facilitates placing the roller 9 in position. In setting the roller in place the gudgeons 14 are inserted in the button 16 in the end of the roller and-the spring 13 is forced back into the recess 14 sufficiently to enable the opening in the opposite end tov engage the stud 1 1.

ICO

The roller is then moved laterally in the direction of the stud 11, and the spring 13 returns to its normal position.

The width of the screen 8 is substantially the same as the distance between the inner faces of the side members 2, and the lower extremity or edge of the screen is attached to a batten 19. In order to receive this batten 19, the upper rail 20 of the upper sash is provided with a longitudinally-disposed rabbet 21, as indicated in Figs. 4 and 5. To the.

stiles 22 and 23, at the upper extremities thereof, I attach resilient plates or leaf- springs 24 and 25, and these project attheir upper ex tremities so as to lie opposite the ends of the rabbet 21. On their inner faces these plates are provided with pins 426, which project inwardly and are adapted to engage recesses 27, which are formed in the extremities of the batten to receive them, as will be readily understood. The batten is of substantially the same length as the distance between the inner faces of the side members 2. In order to enable the batten to be placed in position at a suitable point on the inner face of the side member 2, which lies adjacent to the plate 25, I provide a recess 28. When it is desired to insert the batten, the sash 6 will be drawn down into the position shown in Fig. 2, so that the plate 25 will come opposite to the recess 28. The batten will then be applied4 in the position shown and so that the corresponding opening 27 in its extremity will receive the pin 26 of the plate 25. At the same time the batten will be forced longitudinally, so as to force the spring 25 rearwardly into the recess 28. In this way the batten is moved sufficiently to the side to enable the pin which is carried by the plate 24 to be received in the corresponding opening 27 at the opposite extremity of the batten. The batten is then forced toward the left and the plate 25 resumes its normal position, such as that shown in Fig. 5. From this arrangement it will be observed that the two plates 24 and 25 lie with theirl outer faces against ythe inner faces of the side members 2, and as they are of inappreciable thickness I am enabled to bring the edge of the screen close against the faces of the side members. Furthermore, by this arrangement the batten 19 may be quickly removed or replaced when desired.

Vith the batten attached to the sash as described it should be understood that as the sash 6 is lowered the screen will unroll itself from the roller 9, so that it always fills the open space of the window above the sash, the spring 17 operating to maintain the spread portion of the screen taut and operating also to roll up the screen when the sash is being raised. I provide a very similar arrangement for mounting the lower screen 29. This screen is wrapped upon a roller 30. This roller is attached in an auxiliary'rail 3 1 ,whichis attached tothe under side of the rail 32 of the lower sash 7. I prefer to adopt this arrangement, as it enables me to apply my invention more readily to a sash which is already mounted in a window. In order to do this, I simply cut away the lower side of the lower rail 32 and then apply my special rail 31, so as to give the combined rails at this point substantially the same depth which was formerly had by the original rail. In this way the window closes in the same manner as before. The auxiliary rail 31 is provided on its under side with a longitudinally-disposed groove or channel 33, as indicated most clearly in Figs. 3 and 7. To the stile 34 at the left I attach a plate 35, which projects downwardly into the end of the channel 33, as indicated, and opposite to this plate 35 there is a similar resilient plate 36, which projects down into the end of the channel 33 in a similar manner. The construction of the roller 3() and its manner of attachment to the screen 29 is the same as that of the roller 9 described above. The manner of attaching the roller 3() in position between the plates 35 and 36 is also the same as that of mounting the roller 9 between the plates 24 and 25. For this purpose the plate 35 is provided on its inner face and at its projecting extremity with inwardly disposed gudgeons 37, and these are received in openings 38, as indicated in Fig. 7, in which figure the plate 35 is represented as bent back into abnormal position to facilitate a disclosure of the construction. The plate 36 is provided on its inner face with a pin 38a similar to the pivot-pin 11 described in connection with Fig. 2.

In order to enable the roll 30 to be applied in position at a suitable point on the inner face of the side member 2, which lies adjacent to the plate 36, I rovide a recess 39, as indicated in Fig. 3. en it is desired to place the roller 30 in p'osition, the sash 7 will be run up to a sufficiently high position as to bring the plate 36 opposite the recess 39, and the roller 30 would then be applied to the pin 38'nl and the gudgeons 37 in a manner similar to that described in connection with the mounting of the batten 19.

The lower extremity or edge of the screen 29 is attached to a batten 40, which is adapted to rest longitudinally on the sill 3. The manner of mounting this batten is substantially the same as that of the batten 19, described above, except that a plate 41 is employed only at one side, the said plate being attached over a recess 42, formed in the face of the side member at this point. In this way opportunity is afforded for the plate 41 to be forced rearwardly. The outer face of this plate is provided with a pin 43, which is adapted to be engaged by the adjacent extremity of the batten 40, as will be readily understood. A.

IIO

pin 44 is rigidly attached in the side member 2, which lies opposite, and this pin is adapted to engage the opposite extremity of the batten 40 in the same manner. When applying the batten, the engagement will be first made at the left, as yshown in Fig. 3, and the plate 41 will be forced rearwardly, so as to enable the engagement to be made at the right, as will be readily understood. It is not necessary to recess the sill 3 to receive the batten. I make the channel 38 deep enough to allow for the thickness of the batten as well as the roller 30. In this way the batten in no way interferes with closing the window.

The two screens 8 and 29 are ofsubstantially the same material. By the arrangement adapted of mounting the screens they become extensible, and I am enabled to use screens for both the upper and lower sashes which substantially fill the entire width between the side members of the easement, and, furthermore, either of the screens may be quickly removed when desired.

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent* l. In combination, a casement, a sash movably mounted therein, a member adapted for attachment to the sash and carrying an eXtensible screen, and a resilient plate attached to the side of said sash and affording means for retaining said member, said casement having a recess in the side thereof into which said plate may be forced for attaching said member to said sash.

2. In combination, a movable sash, a pair of oppositely-disposed plates attached to the sides of said sash and having pins on their inner faces, a member adapted to be engaged by said pins and retained thereby, a screen attached to said member, and a Casement in which said sash is guided and having a recess into which one of said plates may be forced laterally in attaching said member `between said plates.

3. In combination, a casement, an upper sash and a lower sash guided vertically therein, a roller attached to the under side of said lower sash and carrying a screen, a batten attached to said screen and attached at the sill of said casement, means carried by one side of said lower sash for engaging said roller, and a resilient plate carried by the o posite side of said sash and affording means fdr supporting the opposite end of said roller, said ca/sement having a recess into which said resilient plate may be forced in mounting said roller.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
