SWINGING WINDOW-SCREEN.

Specication of Letters Ilatent.`

Patented J une 4, 1912.

Application led April 15, 1909. Serial No. 489,977.

To all whom t may concern,

Be it known that I, JOHN H. CoRNLIsoN, a citizen of the United States, residing at the city of St. Louis, in the State of Mis-l souri, have invented a certain new and useful Swinging Window-Screen, of' which the following is such a full, clear, and exact description as will `enable any one skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, forming part of this specication.

The object of my invention is to produce a swinging window screen which will be as simple as possible in construction and vhence will not only be easy to manufacture and low in costbut which will also be reliable in action and not likel to get out of order.

A further object o my. invention is so to construct a screen that it may be made in half lengths and reversed so as to be applied to either the lower or the upper half of the window frame.

In the accompanying drawings, which illustrate some forms of screen made 1n accordance wlth my 1nvent1on, Flgure 1 1s a vertical central section of a window frame provided with my preferred form of screen; Fig. 2 is a slightly enlarged view of the upper part of Fig. 1 showing the screen reversed; Fig. 3 is an enlarged section on the line 3 3 of.Fig. l; Fig. 4 is a view similar to Fig. 1 but showing the full length screen; Fig. 5 is an'enlarged view of the upper portion of Fig. 4; Fig. .6' is a section on the line 6 6 of Fig. 4; Fig. 7 is an enlarged view showing a modification in which the screen is placed between the blind parting strips; Fig. 8 is a view showing means for yieldingly supporting the screen without springs; Fig. E) is a section on the line 9 9 of Fig. 7, and Fig. IOis a section through the lower part of the screen showing a modification.

Like marks of reference refer to similar parts in the several views of the drawings.

15 is the window frame which is provided with a lower sash 16 sliding between guide strips 17 and 18 and an upper sash 19 sliding between the guide strip 18 and the blind parting strips 20.

In my preferred form of screen, as shown in Figs. 1, 2 and 3, the screen 21 is arranged to hear against blind parting strips 20. The end of the screen 21 which is at the top when the screen is in the position 'upper 'in Fig. 5 of the drawings.

shown *in 1 is provided vwith a filling strlp 22 which is of greater thickness than the remalnder of the screen and this filling strip 22 is provided with bearings 23.adapt' ed to engage with pins 24 in the blind part? ing strips 20' at a point slightly above the middle of the window frame. In order to hold the screen in position against the pins 24 sprmgs 25 are provided, one end of each of sald springs being secured to the screen 21 at its central point and the other being 'adapted to engage with a hook 26 inthe blind parting s trip adjacent to the bearing pms 24. It willbe evident that the tens1on of the spring 25 will hold the screen in position. against these bearing pins and at the same timel allow the lower end of the screen to be swung outwardly.

In order to allow for the reversal of the screen so that it maybe used at the upper part of the window frame, I place adjacent to the transverse blind parting strip aprojection or strip 27 leaving a recess 28 adapted to receive the end of the screen opposite "to the filling strip 22, as is showny in Fig. 2.

Adjacent to these recesses 28 is a hook 29 adapted to be engaged with the end of the spring 25 so that the same spring may be used to hold the screen in place` in either position. As the lower sash of,.a Window is somewhat longer than the upper, the pins 24 will come in such a position as to miss the lling strip 22 when the screen is in its position, as shown in Fig. 2 of the drawings. In Figs. 4, 5 and 6 I have shown a modification in which a screen 30 is made the entire length of the window frame and hence can not be reversed. It is held in position in substantially the same manner as the screen 21 when in the position shown in Fig. 2. In this modification, however, it is not necessary-to have a spring which extends to the central portion of the screen as the spring is not reversed. Consequently I use a short spring 31 `as shown in detail the length of the screen 30 it is desirable to have means for securing the lower end of4 it in position when it is not desired to open it and consequently I provide it with a re taining hook 32, as shown in Fig. 6.

On account of"v In Fig. 7 of the drawings I have shown i a modification in which a screen 33, in place of fitting agamst the blmd partmg strips 20, is arranged between such strips so that v is 'obtained a blind mayl bel used in'eonjunetion withthe screen@ -f I'n,f order to:l allow" this, aperturesf'3'4 are "formed inthe 'upper rail of the-` screen and through theseL apertures pass wires 35 attached to-'sprin'gs 36 'which 'arethis modification the screen is beveled at its upper end as shown at-40 and is provided with a pin 41 adapted to engage with 'a suitable aperture in the upper portion of the window frame. As will be seen from Fig. 8 of the drawings, the -screen is Amade slightly shorter in this construction so that it may move upwardly as 1t 1s swung outwardly at the bottom. In place of the spring 31 I use a wire 42 secured to the screen and to the hook 29. It will be evident that in this construction the weight of the screen itself furnishes the yielding means for holding it in position and that the pin `41 retains it against accidental displacement.

In `Fig..10 I have shown a modification which is useful in connection with the form of screen shown in Fig. 7 which lies between -the blind parting strips. In order to allow for the fastening of the blinds 43 the lower portion of this screen is cut away at 44 so as to admit access to the fastening hook 45 of the blind. This-cut away portlon 44 is covered by a board 46 which is secured in position by means of pins 47 in the bottom of the window frame and detachable hooks 48.

I-Iaving vfully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l.- In combination with a window frame,

" a swinging screen, longitudinally extensible springs' permanently fastened at corresponding ends to the inner face of the screen and their other ends pivotally connected to and readily detached from the frame, allowing the entire screen to be moved away from the frame and held in parallel or oblique planes thereto, said springs serving, when under tension, to hold `one edge of the screen in revoluble contact with the frame and normally holding the inner -face of the screen -yieldingly against `the frame, as set forth.

2.-In combination with a window frame, a swinging screen, longitudinally extensible springs loosely connected at corresponding ends to the inner face of the screen and to said frame, allowing theentire screen to be moved away from the frame and held in parallel or oblique planes thereto, said springs serving, when under tension, to hold one ledge of th, iscreenfrevolublyfin contact with the frame and normally'ho'lding 4the inner face of the screen yieldinglyagainst the 3.
