FRANK L. RICKER, OF PORTLANIL MAINE, ASSIGNOR TO AUSTRAL WINDOW COMPANY, OF NEW YORK, N. Y., A CORPORATION OF MAINE.

WINDOW-SCREEN.

cation. 7

My'invention relates to window screens and it relates particularly to screens adapted to be used on the so-called Austral or balance sash windows. These windows are illustrated in United States Letters Patent No. 821,510 issued May 22, 1906 and they consist of an upper and lower sash with the usual meeting rails, the lower portion of the upper sash and the upper portion of the lower sash being pivoted at a point a short distance from the end to the ends of a pair of centrallypivoted balance levers which in turn are pivoted tothe parting strip. The upper end of the'upper sash and the lower end of the lower sash are pivoted in a vertical slot in the casing so that they are capable of vertical movement. As a result of this construction the upper end of the lower sash may be swung inwardly and the lower end of the upper sash outwardly at the same time opening a space at the top and bottom of the window. These windows while they have gone into extensive use have always been difficult to screen. p

The objects of my invention are to devise a screen whichwill perfectly close the window opening whether the sash are opened or closed, which may easily be applied to any window of this character, which will present a neat and attractive appearance and which will cut off as little ofthe air supply as possible. These objects I accomplish bv means of the window screen hereinafter described 7 and claimed.

Application filed October 24, 1913. Serial N 0. 796,987.

F ig. 4 is a section on the line wac of Fig. 1, and Fig. 5 is a vertical section showing a modification.

Referring to the drawing, a represents the window casing, b is, the parting strip, 0 the upper sash, d the lower sash and 0 and cl the meeting rails. The upper and lower sashes are connected with the casing by means of a pin and vertical slot connection as indicated by dotted lines in Fig. 1. This enables them to slide verticallv in the casing'a limited distance. The balance levers are pivoted to theparting strip and to' the upper and lower sash. As here shown, the lever e is formed flush on the inner surface and it has a hub or enlargement in the center and a pivot on the outside which extends into the parting strip. (See Fig. 4). In screening this window I make use of an upper and a lower screen each approximately the size of its corresponding sash. The upper screen fits in the casing above thelower sash and against the inner face of the parting strip. The lower screen fits the casing and outer surface of the parting strip. In other words each screen fits against the face of the parting strip opposite the sash.

As here shown, the upper screen f fits against the face of the parting strip opposite the sash c and the lower screen 9 fits the face of the parting strip opposite the sash d. The screens are fastened in place by dogs f, g which engage recesses in the sides of the casing in the well known manner. The screens which are on opposite sides of the partlng strip are connected bv a connecting portion which extends through a space or opening formed between the meeting rails and makes with the screens a complete closure of the window opening. The connecting portion which joins the screens is preferably made separable so that the screens mav be detached from each other and I prefer to form an interlocking separable joint within the opening. I

As here shown, the upper screen is provided with two thin strips preferably of metal superposed on one another and each bent at an agle to form an upper vertical portion which is attached to the lower end of the screen and a flat socket or recess extending obliquely downward This socket or recess extends substantially the entire width of the screen but it is cut away at the ends to embrace the hub of the lever e as shown in'Figs-3 and 4. 7 On the upper edge of the lower screen is a thin strip a bent at an angle toform avertical portion secured to the upper end of'rthe lower screen and an inclined portion extending diagonally upward and engaging the socket formed'by the strips h and h. striph is bent so as to give-a flaring opening to the lower end of the socket into which the strip 11 will readily slide. The joint thus made is easily put together and, takenapart and it makes. a tight joint which effectually excludes rain, snow and air whenthe window is closed. The screens I have illustrated are metal screens but wood screens may be applied in identically the same manner to these windows, WVhen-the' screens are removed from. the windows the opening .be

1 tween the meeting rails maybe filled by a filling piece which may besecured in place in any suitable manner. Screens applied in this manner to this class of windows have theiadvantageof making artight joint with the face of the partingstrip and with the inner surface of the casing they offer a minimum obstruction to the admission of air when the window is open. The windows may be freely opened and closed without interfering with the screens and they involve little or no change in the construction of .the window. Other separable joints differingfrom the one here shown may be used but this joint has many practical advantages, especially when used with metal screens.

Instead of having an opening between the meeting rails they may be made to fit closely I apart.
