WINDOW-SCREEN.

Specification of Letters Patent. I

Application filed December 30, 1911. Serial No. 868,788.

To all whom it may concern:

Be it known that I, THOMAS H. RANEY, a citizen of the United States, residing at Chapel Hill, in the county of Orange and 6 State of North Carolina, have invented a new and useful Window- Screen, of which the following is a specification.

This invention relates to window screens, using the term in a generic sense. as includin screens for windows transoms doors and the like adapted to the exclusion of flies, mosquitoes and'other insect pests.

A particular object of'the invention is the provision in such a screen of means for aflording access therethrough to outside shutters, awning cords and other exterior equipment for the operation of the same without the necessity of removin the screen bodily, or raising the same and t us leaving 80 a large opening for the entrance of insects.

The invention as thus outlined and hereinafter particularly claimed will be readily understood from the following detailed description, taken in connection with the accompany'ing illustrative drawings,'showing a preferred embodiment of the same and also one modification.

In these drawings:-'F1gure 1- 1s a perspective view representing the inside of a full-length window screen' embodying the invention. Fig.2 is a partial outside elevation' of the same. ,Fig. 3 is a similar inside view partly in section, showing the panels in one position of adjustment. Fig. 4; is an .5 inside elevation with the panels otherwise adjusted. Fig. 5 is a vertical section, taken between the two sides of the sliding panels.

Figs. 6 and 7 are elevations showing the inside of the screen embodying a modification of the invention.

I Referring first to Figs. 1 to 5 of the drawings, these figures show'a full-length window screen especially adapted to beniounte'd outside the sash upon the blind stops. The

frame proper comprises the usual stiles 1 and top and

bottom rails

2 and 3. The lower portion of the frame is also provided with aspacing rail 4, arranged at a slight distance above the bottom rail and forming 5. The upper face of the bottom rail 1s provided in the median plane of the screen with a track member 6 and the bottom face of the spacing rail with a similar track 7 arranged in opposition to the track 6. These track mem-' bers 6 and 7 may comprise sheet metal strips let into the spacebetween the two parts of the bottom. rail and spacing rail, as shown in Fig. 5-, such strips being secured to the rails by tacks, brads, or screws 8.

Screen panels

9 and 10 are provided on their upper and lower edges with grooves engaging the tracks ,6 and 7 whereby they are mounted Patented May 'i, 1912.

for horizontal sliding movement within the planeof the screen and between the bottom rail and the spacing rail. The aggregate width ofthetwo

screen panels

9 and 10 is less than the width of the screen frame proper, and preferably they have a combined width equal to substantially two-thirds of the total wldth of the screen frame, so that when the

screen panels

9 and 10 occupy a position at the opposite sides of the panel opening, as shown in Fig. 5, there is left a space between such panels.

The bottom and spacing rails are provided in their side faces with

track members

11 and 12, projecting from the plane of the screen frame at substantially right angles and a third panel 18 is provided in its rear face with grooves adapted to engage

thesaid track members

11 and 12 to guide the same for sliding horizontal movement over the full width of the screen frame and in a plane parallel thereto, the front faces of the bottom and spacing rails and of the

screen panels

9 and 10 being in close contiguous relation to the rear face of the screen panel 13.

Spanning the screen frame and preferably at points immediately above and below the

screen panels

9 and 10 are supporting wires upper edge ofv the panel while the lower wire 15 is preferably threaded through the stiles of said panel. It will thus be seen that the

panels

9 and 10 are independently slidable in the plane of the screen so as to leave an opening in the center of the screen,

as shown in Figs 3 and 5,-or 'at either side of said frame, while the third panel .13 is slidable in a plane parallel to the frame to control the opening left by the

panels

9 and 10. a

That portion of the screen above the spacing rail is covered with screen cloth in the usual manner, while the portion below the spacing rail is left uncovered. Each of the screen panels is also covered with screen cloth, and when the panels occupy the position,.shown in Fig. 1, the entire screen frame is covered and in this normal posit-ion the admission of insects is effectually prevented. If it is desired to reach the'shutter or blind on the right hand side, the panel 9 is shoved to the center, as shown in Fig. 4, leaving an opening on that side sufiicient only to accommodate the hand or arm. To reach the left hand shutter,'the panel 10 is restored to its normal position and the panel 9 shoved to the right thus making an opening on the left hand side of the screen. If it is desired to reach the shutters at the meeting edges, the center panel 13 is shoved to one side, as shown in Fig. 3.

It will be observed that the lower rail 3 is provided with a notch 21 to accommodate the catches of the shutter, so that the shutter can close tightly against the screen, as the keepers for the shutter catches are usually arranged in the plane containingthe blind stops. When the blinds are closed, the catches occupy a posit-ion in this notch beneath the screen frame, and the screen panel 13 is for this reason made of 'sufiicient height to extend to the bottom of the bottom rail 7 3, and thus control the opening of the said screen frame adapted to be mounted on the stops inside the sash, under which circumstances"; it is necessary to afford access there-' through to the sash in order to raise and lower the same. In this case it is not only desirable to be able to operate the lower sash, but also to be able to reach the upper sash to draw it downward for top ventilation. In this modification of the invention I have shown the stiles 22, the top rail 23, and the bottom rail 24 and the spacing rail 25 arranged midway of the height of the' screen. lso middle stiles 26 forming therebetween a vertical panel opening 27. The middle stiles 26 are spaced apart a distance nearly sufficient to accommodate the hand or arm. In this case, as before, the screen frame proper is covered with cloth with the exception of the panel opening 27. The

front faces of the spacing rail 25 and the bottom rail 24 are provided with

inset track members

28 and 29, which cooperate with grooves formed on the inside of a vertical panel 30 to guide the same for horizontalmovement in a plane parallel to that of the screen frame, and with the opposing faces of said panel and the middle stiles 26 in contiguous relation. In this case also guide wires 31 and'32 are secured at one -end to the studs33 and 34 and at the other end wound upon

thumb screws

35 and 36. Under normal conditions the panel 30 0(: cupies the position shown in Fig. 6. When it is desired to adjust the height of the sash, thepanel 30 is shoved to one side affording access thereto through the opening 27.

I am aware that window screens heretofore have been provided with panels afford-v ing access to the blinds and the like, but in the constructions known to me, the arrangement has been such as to leave exposed a large opening during the manipulation of the blinds and sash, which permits the entrance of insects, and it has been "my particular effort to minimize this disadvantage as much as possible, by providing in the preferred embodiment shown cooperating panels having such slidable overlapping relation one to the other as to reduce the necessary opening as much as ossible, and in the modified form by provi ing a very narrow opening, extending one half the height of the window in a central line to likewise enable the adjustment of the sash to be accomplished with the least exposure.

What is claimed is 1. A Window screen having an opening therethrough, a. track spanning the'screen frame and projecting laterally from the plane of the screen, a screen panel disposed against the face of the screen over the opening and sliding on the track, supporting wires spanning the screen adjacent the rails of the track and slidably connected to the screen panel, a fixed connection between one end of the wires and the'screen, and a tensioning' connection between the otherend and the opposite side of the screen.
