(on. ea-es) I 2 Claims.

This invention relates to a screen for sliding closures in general, and for windows in particular, having means for compactly carrying a window screen and actuating means to extend the screen when desired.

The primary object of this invention, is to provide an improved screen for windows which may be left in place throughout the year, and provided with means whereby the screen may be extended to cover the opening in the window frame, as desired, when the sash is raised.

More particularly, it is anobject of this invention to provide an improved window screen construction comprising an apparatus whereby a strip of mesh wire fabric can be retained in a rolled position in a window sash, and means connected to one end of said fabric engageable with the window frame causing the fabric to be unwound when the sash is raised or lowered.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, which illustrate a preferred form of the invention, and wherein:

Figure 1 is a side 'elevational View of a window provided with sliding sashes, and illustrating the invention shown applied to the lower sash and in an inoperative position,

Figure 2 is a View similar to Figure 1 showing the screen in an extended position,

Figure 3 is a transverse vertical sectional View taken on the line 3-4 of Figure 2,

Figures 4 and 5 are horizontal sectional views taken on the lines 4-4 and 5-5, respectively, of Figure 2, t

Figure 6 is a vertical sectional view taken on the line 6-6 of Figure 5, and

Figures 7 and 8 are end views in elevation of the opposite ends of the low-er rail of the lower sash.

Referring more particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout the difi'erent views, Hi designates generally a window frame provided with an opening I l in which is mounted the upper sash l2 and the lower sash l3.

As best seen in Figure 3, the bottom rail it of the lower sash I3 is provided with a longitudinal bore 15, which is preferably cylindrical shaped, and a slot to in the bottom edge, extending the length of the bore 5 and communicating therewith. The plates H and It are mounted on the opposite ends of the rail It, in a countersunk position, as best seen in Figure 4, to close the opposite ends of the recess l5.

Lil

A spring winding roller designated generally it is disposed longitudinally and centrally of the recess is, and comprises a rod 29 having a polygonal shaped head 2| at one end adapted to fit into a corresponding opening 22 in the plate ll, and a head 28 at its opposite end provided with a reduced shank 2t adapted to be journaled in an opening 25 in the plate 18.

A coil'spring 26 is mounted on the rod 20, and extends substantially the length thereof, with one of its ends secured to said rod at 27. A tube 23 encloses rod 20 and spring 26 and extends from theplate ll to the plate It, and is adapted to be rotatably mounted relatively to the rod 2%. The opposite end of the spring 25, designated 29, is secured to the tube 28.

A strip of mesh wire fabric, designated 3%], has one of its ends suitably secured to the tube 23, and is adapted to be wound thereon as indicated at 3! with its opposite end extending through the slot 55. A base member 32 is provided with an arcuately shaped slot '33 in its upper face, in which the free end 34 of the fabric ill! is positioned and secured by any suitable The tension of the coil spring 26 will normally cause the fabric 39 to be wound on the roller it to hold the base member 32 in. engagement with the bottom edge of the rail I l, as seen in Figure 1.

Referring particularly toFigures 5 and 6, it will be seenthat the base member '32 is provided with a wedge shaped slot disposed intermediate of its ends, designated 35, and with the longitudinally disposed opposed bores 36 which extend from the opposite ends of the member 32 to the slot 35. Reciprocally mounted in the bores 35 are the corresponding rods 31, which are slightly longer than said bores, and which are provided with the heads it on their inner ends, which are disposed in the slot 35. A wedge shaped cam member 39 is provided with the slots til, disposed adjacent its opposite corresponding edges and opening outwardly of its converging end.

The slots to are provided with the restricted portions ll which open outwardly of the opposite corresponding edges of the member 39. Member 39 is adapted to be slidably mounted in the slot 35 with the heads 33 slidably positioned in the slots 48 and the rods 3'! extending through the restricted portions ti.

As best seen in Figure 5, the frame It is provided with the oppositely disposed correspondingly positioned recesses 42 which open inwardly of the guideway of the frame in a position to align with the bores 35 when the base meme her 32 is in its lowermost position as seen in Figure 3. Base member 32 is provided with the arcuately shaped cut-out portions 43 which communicate with the slot 35 and by means of which the outer edge of the member 39 may be grasped. Member 39, as seen in Figure 3, is provided with a recess 44 in its upper side adjacent its diverging end to form a fingerhold for actuating the member 39 when the base member 32 is in its lowermost position.

As seen in Figures 1 and 2, rail 14 is provided with an arcuately shaped outwardly tapering recess 45 communicating with the recesses 43 when member 32 is in the position as seen in Figure 1 to expose the finger grip 44 and to form a fingerh'old for raising the sash l3 relatively to the member 3 2.

As seen in Figures '7 and 8 the base members l1 and I8 are preferably removably secured to the ends of the rail l4 by means of the fastenings 46.

From the foregoing it will be seen, that when the member 39 and the bolts 31 are in a retracted position, the tension of the spring 26 will retain the member 32 in engagement with the bottom edge of the rail I 4 so that it will be raised or lowered therewith. When it becomes desirable to employ the fabric 30 as a window screen for the frame l0, sash I3 is moved to its lowermost position and the cam member 39 is pushed inwardly or projected to project rods 31 into engagement with the recesses 42 so that when the sash I 3 is again raised the member 32 will be held rigidly relatively to the frame in to unwind fabric 30- to close the opening II in the frame In formed by raising the sash 13. By withdrawing or retracting cam 39 bolts 3'! will be retracted out of engagement with the recesses 42 and the spring 26 will raise the base member 32 back into engagement with the rail l4, as heretofore described. It will thus be seen, that during the winter or when a window screen is unnecessary the invention can be in its inoperative position to move with the sash l3 as indicated in Figure 1, or when a window screen is necessary as in the summer cam 39 can be projected so that the apparatus will be in its operative position to form a window screen for the opening ll whenever the sash I3 is raised.

While the invention has been illustrated and described in connection with the lower sash J3, it may obviously be mounted on the top rail of the upper sash l2 and inverted in its position to close the opening formed by lowering the sash l2 when the device is in its operative position. The device is also adapted for use with any other form of sliding closure and may employ any other type of flexible material in lieu of the mesh wire fabric, as for example mosquito netting.

Various other modifications and changes may likewise be made, and the construction and arrangement of the parts forming the invention may also be varied, as the drawings and description are only intended to illustrate a preferred form thereof, and the right is reserved to make such variations and changes as do not depart from the spirit and scope of the invention as hereinafter defined by the appended claims.

I claim as my invention:

1. A look for sliding closures comprising a member slidably mounted in a closure frame, rods, having heads on their inner ends, slidably mounted longitudinally of said member, a wedge slidably mounted transversely of said member and provided with converging slideways having portions complementing said heads for slidably engaging the adjacent ends of said rods for projecting and retracting said rods relatively to the member, and said rods forming bolts for engaging the closure frame, when in a projected position.

2. A window screen latch for a rolling window screen mounted on a spring roller carried by a sliding sash, comprising a bar fastened to the free end of the window screen and supported thereby to normally move with the sash, bolts, having head-s on their inner ends, slidab-ly mounted longitudinally of the bar, said bar having a transverse V-shaped recess intermediate of its ends, and a wedge slidably mounted in said recess and provided with converging guideways having portions complementing said heads for slidably engaging the adjacent ends of the bolts for projecting and retracting the bolts, the remote ends of the bolts extending beyond the ends of the bar, when in a projected position, for engaging a frame in which the bar is disposed for latching thebar in a fixed position relatively to the frame.
