EXTENSIBLE WINDOW-SCREEN.

Specification of Letters Patent. Patented Oct, 1, 1912,

Application filed May 13, 1911.. Serial No. 627,021.

ble Window-Screens, of which the following is a description, reference being had to the accompanying drawlngs, forming a part I hereof.

My invention relates to extensible window 1 screens and has for its object to provide means by which a single window screen may I be readily adjusted in width so as to fit windows of different width and will automat1-:

cally operate to fit a window in which the width at different levels may differ to a substantial extent.

With this object in view my invention consists in the construction and combination of elements hereinafter described.

Referring to the drawings Figure 1 is a front View of a window screen embodying my invention in place in a window frame; Fig. 2 is a horizontal sectional view taken on line 2-2 of Fig. 1;-Fig. 8 is a perspective view of the metal strip Fig.4 is a perspective view of the preferred form of traveler; and Figs. 5,6 and 7 are horizontal sectional views of modified forms of the traveler.

at their ends to the top bar 3 and bottom bar 4, also shown as formed of strips of wood.

though if preferred the stile and top. and

bottom bar may be of metal either solid or bent up of sheet metal. These-stiles and top and bottom bars form a frame of usual form to carry the netting 5 which is secured at its edges in any'usual manner. From the outer edges of each of the stiles extends inward a longitudinal slit 6 preferably extending inward nearly to the inner edge Into this slit 6 near the top and near the bottom of the stile extends the tongue 7 of a traveler which is provided at its outer end with a pair of recurved arms 8 and 9 which are adapted to inclose the edges of a guide rail 10 which is secured in any convenient manner as by screws 11 to the sides of the window frame. The travelers are each formed from a strip of sheet metal preferably somewhat over an inch wide which is bent at its middle until the two portions are close together, the end portions being each bent outward and then bent inward so that the extreme ends are both directed inward and are separated a short distance. The curve of the arms 8 and 9 will correspond somewhat to the cross section of the guide rail 10' which may be conveniently formed from a half round meta l rod preferably slightly flattened where it rests against the side of the window frame. The tongue 7 of the traveler is slotted as shown at 12 about midway between its upper and lower edges the slot extending parallel with the upper and lower edges from a point near its inner end to a point a short distance from the arms 8 and 9. The slot '12 is of just sufficient width to permit of the passage of a pinornail13 which is driven into the faceof the stile. The traveler is thus held against removal but is permitted to move in or out a distance determined by the length of the slot.

Between-the flat portions which form the tongue 7 'is arranged a strip of metal 1 1 ex- 1: and-as thestrip is made ofsuch width that In the drawings, '1 and 2 are the stiles or L side bars of a window screen here shown as formed of strips of wood suitablyjoined,

its outer edge will extend between the inner ends of the curved arms 8 and 9 so as to be nearly in contact with the face of the guide strip 10.

In order to place the screen in position in a window the guide rails are first inserted through the travelers, one "through the travelers of each stile and the screen with the guide rails is then placed in position in the window frame and the rails screwed or otherwise fastened to the sides of the window frame. Should the window frame be wider. than the screen the travelers will be pulled out afgreater or less distance dependirregularities in the width of windows are compensated for. At the same time no opportunity is afi'orded for the entrance of flies.

Instead of the half round guide rail a sheet metal guide rail having a depressed center as shown at 16 in Fig. 6 may be used, the form of the recurved arms 8 and 9 being guide rails are more than the normal distanee apart and that in such movement they carry the filler strip with them.

In order to provide for removing the screen from the window the rails may be made in two partsseparated at 20, so that by removing a single screw 11 near the upper end of the lower part of each rail the end of this part of the rail maybe sprung inward sufliciently to permit the arms 8 and 9 to pass off when the screen is slipped upward. In this way the screen may be removed and by a reversal of the operation may be put into place provided, of course, that the screen does not exceed in height one-half the height of the window casing.

Having thus described my invention, what I claim is:

1. In a window screen the combination with the stile having a slit extending inward from its outer edge, a guide rail secured to the side of the window frame and a relatively short traveler having a tongue extending into the slit of the stile and having its free end adapted to grip the guide, rail and be held against disengagement therefrom.

2.-In a window screen the combination with the stile having a slit extending inward from its outer edge, a guide rail secured to the side of the window frame and a relatively short traveler having a slotted tongue extending into the slit of the stile and movable inward and outward therein, a pin extending through the slot of the tongue -to limit the movement of the tongue, the

free end of the traveler being adapted to grip the guide rail and be held from disengagement therefrom.

3. In a window screen the combination with the stile having a slit extending inward from its outer edgethroughout its length, a

If preferred, in-

guide rail secured to the side of the window frame, a traveler having a tongue extendin into the slit of the stile and movable inward and outward therein and having its free end adapted to engage the guide rail and be held against disengagement therefrom and a filler strip extending in the slit of the stile from end to end thereof, and means by which the filler strip is caused to move with the traveler in its outward movement.

1-. In a window screen, the combination of a stile having a slit extending inward from its outer edge throughout its length,

a guide rail secured to the sideof the window frame, a traveler having a slotted tongue extending into the slit of the stile and movable inward and outward therein and having its free end adapted to engage the guide rail and be held against disengagement therefrom, a filler strip extending in the slit of the stile from end to end thereof and having slots corresponding to the slot of the tongue, a pin extending through the slots of the tongue and filler strip to limit the movement of the tongue and filler strip and means by which the filler strip is caused to move with the traveler in its outward movement.

5. In a window screen the combination of a stile having a slit extending inward from its outer edgethroughout its length, a guide rail secured to the side of the window frame, a traveler formed from a strip of metal to form a tongue having the outer ends of its side port-ions adapted to engage the guide rail and be held againstdisengagement therefrom, the traveler extending into the slit of the stile and movable inward and outward therein, a filler strip extending in the slit of the stile from end to end thereof and arranged between the portions forming the tongue of the traveler.

6. In a window screen the combination of a stile and a slit extending inward from its outer edge throughout its length, a guide rail secured to the side of the window frame and having the portion thereof in contact with the side of the window frame of less width than the opposite face, a relatively short traveler having a tongue extending into the slit of the stile and movable inward and outward therein and having its free end adapted to extend over the side edges of the guide rail and to engage the inner face of the rail.

This specification signed and witnessed this 15th day of April A. D. 1911.
