SCREEN FOR USE WITH. XVINDOTVS OF THE SLIDING-EASE TYIEE.

Application filed October 1, 1927, Serial No. 223,397, and in Great Britain June 20, 192?.

The invention relates to an improved screen for use with windows of the sliding type.

According to the present invention, I provide a wire-mesh or like screen adapted to be associated with a widow of the type stated so that, when the window is openechthe screen moves automatically into position over the opening, and, when the window closed, the screen moves automatically out of position so as not to hinder the access of. light or obscurethe view throughthe window.

Preferably, the wire-mesh or like screen isv secured at one end to the window sash and is adapted to move between guide members carried by the window frame or sill. The screen may be held in spaced relationship, if necessary, with respect to the window sash, and, if desired, be adjustable towards or away from the sash.

Referring to the drawings Fig. 1 is an elevation, illustrating one embodiment of screen as applied to a window.

Fig. 2 is a section on line 11-11 in Fig. 1. Fig. 3 is an elevation of a further embodiment.

Fig. 4. is a section on line IV-IV in Fig. 3, but shows the screen partly collapsed.

Fig. 5 is a plan view, partly in section, of the screen detached;

Fig. 6 is a fragmentary view illustrating a slight modification.

In one embodiment of my invention as shown in Figs. 1 and 2, as applied to the lower sash of a window, the screen comprises a rectangular frame 1 over which is stretched a. piece of wire mesh 2. Adjacent each side, the screen is fitted with an upright metal guiding strip 3, the two strips being kept in spaced relationship to the screen by a distance piece 1 at top and bottom.

The bottom of each strip 3 with its corresponding distance piece 4 is secured to the wire-mesh screen by a bolt 5 fitted with a wing-nut 6. At the top, each strip and distance piece are secured to the wire-mesh screen by a bolt 7 which has at one end a shoulder 8 bearing against strip 3 and a wing nut 9 and at the other end a screwed part 10 which passes through a hole 11 in the bottom bar of the window sash 12. This bolt serves to attach the top edge ofthe screen to the sash frame, the two nuts 13-14= being adapted to grip therebetween the said bottom bar of the window sash.

Guides for the screen are secured on the window frame 17 and each comprises a bolt 18 having an integral apcrtured attachment portion 19 adapted to be secured at oneend to the window frame and having a bifurcated outer end 20 provided with a pair of spaced pinsfll extending transversely thereof, a roller 22 being rotatably mounted on each pin. The bolts 7 and 18 may be made extensible and cont-ractible so as to allow a standard screen to be fitted to windows hav ing sills of different widths.

.l Vhen the screen is in use, the upright strips at the sides of the screen are adapted to pass through the bifurcated end, between the pairs of rollerscarried from the window frame, the outermost roller in each case projecting between the strip and the wire-mesh.

It will be clear from the foregoing that, when the Window sash isin its lowerposition, and the window is closed, the wiremesh screen is located at the side of the wall of the building, below the window sill and thus does not interfere with the view out of the window and does not hinder-the access of light. On the other hand, whenever the window sash is raised, the wire-mesh screen is drawn upwards therewith to cover the opening between the bottom bars of the sash and window frame. it

lnthe further embodiment shown in Figs. 3, 4L and 5 the screen member is made in three sections marked 30, 31 and 32, each section as before comprising a rectangular frame on to which is fixed a piece of wire-mesh 3 One section 31 is provided on both sides with spaced channel members 35. Two such chan nel members are provided on each side in the particular construction illustrated. The other sections 30 and 32 are provided on one side only with a bar-like projection 36, which extends across the, screen from top to bottom thereof, and is fixed in spaced relationship to the screen by pins 37, the projection on section 30 extending slightly beyond the lower edgethereof and the projection on the section 32 extending slightly beyond the upper edge thereof. These bar-like projections slidably engage in the channel members and are so arranged that the sections can be moved into a position in which they extend one beyond the other as shown in Fig. 3, or into a position in which they lie side by side. The projections and channels are so con structed as to prevent their disengagement.

The section 30 is provided with two spaced attachment devices by which it can be detachably secured upon the window sash, this device comprising two plates 41, the plate 40 "having a shoulder 42 and a screwed shank .43, which latter can be passed through a hole in a projecting boss part 44 on the frame and receives a wing nut 45, serving to clamp it to said frame. The plates 40, 41 are provided with slots marked 46 and 47 respectively through which pass studs 48 having wing nuts 49. 7 By this means the devices can be extended and contracted'so as to make a standard screen applicable to windows having various shapes and sizes of'sills. The plate 41 hasa; screwed-shank 50 with a plain nut 51 and. a wing nut 52 by which it can be detachably clamped upon the sliding sash of the window- The screen sections are supported by a guiding member comprising two plates 55, 56, one of which has a slot 57 and the other carries two studs 58 whichproject through the slot 57 and receive'nuts 59 so that the guiding member is extensible and contractiblewithin limits, for a similar reason to that for which the attachment device is extensible and contractible. The plate 56 is provided with an apertured attachment portion 60 adapted to be secured to the window frame by screws 61, and the plate is provided with an apertured attachment portion adapted to be secured to the window frame by screws 61, and the plate 55 is provided with a'bifurcated end 63 carrying two pins 64 on which are rotatably mounted rollers 65.

Between these rollers 65 is disposed a guide rail 66 fixed in spaced relationship upon section 32. This guiding member therefore not onlyserves to support the sections, but also allows the section 32 to slide in relation thereto. It will be readily understood that if the window sash is in its lower position the sections will lie side by side, but when the sash is raised the sections will be raised successive ly to cover the opening; If the sash is moved into the position shown in 4 section 30 alone is raised, if now the sash is again raised section 31 will be lifted and if the sash is moved to open fully the window all three sections will be lifted, and will extend one above 7 the other to close the window opening.

Instead of the guiding member being in the form of strips of metal, this may be constituted, as shown in Fig. 6, by a piece of wire 70 attached to the screen frame by bending it over the distance pieces 71 and forming eyes in the wire, one at each end thereof, to engage the bolt 74, in which case instead of the rollers, the guiding member 72 is provided with an eye 73 through which the wire passes.

The invention is applicable to ordinary window sashes without any alteration in the structure or arrangement thereof, and, when not required, can be readily detached and stowed away. The screen is particularly adapted for use on the outside of a window, but can be disposed, if convenient, on the inside thereof.

I claim 1. A unitary screen structure for application to existing sliding sash windows, comprising, a screen member, extensible and contractible attachment means for detachably securing one end of said screen member to the window, guide rails extending vertically across said screen member, distance pieces spacing said guide rails from the screen member, extensible and contractible guide members adapted to be attached to a window frame and rollers rotatably mounted on said guide members adapted to contact with said guide rails, to guide and retain the screen member in its proper position.

2. A unitary screen structure for application to existing sliding sash windows, comprising, a plurality of screen sections, means slidably interconnecting said sections so that they can extend one beyond the other and contract to lie side by side, extensible and contractible means for supporting the screen sections, and extensible and contractible means for attaching one screen section to a moving part of a window. whereby the screen moves extensively to close the opening when the window is opened and contractibly to reduce the size of the screen when the window is closed.

In testimony whereof I afiix my signature.
