LOUISE E. DODDS AND WILBERT J. DODDS, F DETROIT, MICHIGAN, ASSIGIIOB-S TO THE W. J. BAKER COMPANY INCORPORATED, OF NEWPORT, KENTUCKY, A CORPORATION OF KENTUCKY SOREENED WINDOW Application filed April 27,

This invention relates to improvements in screened window operating devices, and

refers more particularly to such arrangements applicable to casement windows having pivotal sashes.

Theinvention aims, among other things, to provide a screened window operatmg devlce wherein a rod is mounted on the latch on the pivotal sash and extends through the wards adjacent the side of the screen remote from the sash when the 'latter is closed; wherein the rod may be employed for opening the window to any desired extent or for closing the same; wherein means are provided on the rod for allowing that portion of the latter which extends on the inner side ofthe screen to lie vertically downwards ad jacent the latter when the window has been partially opened; wherein a plate on the screen through which the rod passes is provided with means for engaging recesses in the rod so that the sash, when opened to varying extents, may be held against accidental movement; wherein means are provided for covering the otherwise exposed portion of the opening through the plate through which the'rod passes when the sash is in open position and the engaging means on the plate are coacting with some of the rod recesses; and wherein the rod is readily detachable from the latch so that the latter may be used in the normal manner without the rod when the screen is not in use.

'With these and other objects and advantages in view which will become apparent as the specification proceeds, the invention is hereinafter more fully described with the aid of the accompanying drawings, in which:

Figure 1 illustrates a screen in position on a window frame with the sash in closed position.

Figure 2 is a fragmentary perspective view, somewhat enlarged, showing a portion of a window frame with a portion of a screen against it and a portion of a sash in slightly opened position.

OPERATING DEVICE 1929. Serial No. 358,724.

Figures 3 and 4 are sectional views show ing the screen in position on a window frame with the sash in the latter in closed and partially opened positions respectively.

Figure 5 is a sectional view showing a portion of awindow frame and a portion of its sash in fully open position.

Figure 6 is an enlarged detail of the plate on the screen through which the rod passes and a section through the latter.

Figure 7 is an enlarged detail showing a preferred means of fastening one side of the screen to the frame, and

Figure 8 is an enlarged detail view of the latch and the pivotal connectionof the latter to the rod.

Referring to the drawings, 1 designates a window frame having a screen 2 mounted on its inner side. The screen may be supported as by upwardly projecting pins 3 secured to the frame which pass through eyes 4 projecting from the screen, or in any other desired manner. It is however preferable that the screen be pivotally mounted on the frame, and it may be held in closed position at its opposite side in any desired manner. A preferred means of holding this side of the screen is to provide a recess 5 in its face adjacent the frame and to securea resilient member 6 in the latter. The said member is adapted to coact with a projection, such as the head of a screw 7, which extends inwardly from the frame 1. In locking the screen 2 rises on the pins 3 as the member 6 passes over the top of the screw head or other projection 7, and the latter then engages the member and holds thescreen in closed position. A knob 8 is arranged on the front of 'the screen 2 by which the latter may be raised latch member 11 terminates at one end in a T locking member 12 adapted to engage the inner side of the frame 1 to' hold the sash in closed position and at its opposite end in a handle 13. Projecting inwardly in line with the axis of the shank 11a is a projection 14 the purpose of which is hereinafter described. v I r p i V 7 On the inner side of the screen 2 and attached preferably to its vertical margin on its side remote from the eyes is a plate 15 in front of which the screening 2a is partly cut away as indicated at 2?; in Figures 3, a and 5. Through this plate a substantially circular aperture 16 is provided for the passage of a rod 17, and .18 designates a slot cut through the said plate and having its upper end opening into the said aperture.

In the outer end of the rod 17 a'slot 19 is formed intowhich the'latchprojection 1 1 extends. The latter andv the rod end are pivotally connected as by a pin 20. The distance of the pin 20 from the latch 11 should be such that when the sash 2 is in closed position the rod 17 may lie vertically adjacent the inner sideflof the screenas shown inrFigures 1 and 3, at which time the latch locking member 12 is in engagement with the window frame 1. V WVhen the latch locking member is turned so that it is disengaged from the window frame thepin20 is substantially vertical and the projection let is therefore free to swingwith the sash 9 outof alignment from the rod 17 as shown in Figures 1 I and 5. l

When the sash is partly'openas shownin Figure 4, the rod 17 extends partly outside and partly insidethe screen 2, and'if the said rodwere rigid it would project some little distance horizontally-inwards through the portion 17 a is pivotally connected to its outer portion, by a pin 22 arranged preferably substantially at right angles to the pin 20. Thus when the sash is partly open theinner trod portion 17ais free to lie vertically adjacent the inner side of the screen as shown in Figure l. v v V At various distances along the rod 17 and its extension 17 a opposed recesses 23 are provided'therein which are adapted to be en gaged by the vertical marginsof the slot 18 in the plate 15, thus providing means for holding the rod .17 or its extension 17 a, and v the sash 9 against accidental -movement. Moreover when the rod 17 or its. extension 17a, is engaged by the margins of the said slotted portion at least a small part of the aperture 16 is'uncovered.v To cover this a pivotal guard 24 is mounted on the plate 15 the lower margin 241a of-whichis preferably formed to fit around the upper portion of the rod 17, or its extension 17a. 1 j

The frame of the screen 2 may, of course,

be made of any desired section. In the present instanceits front and rear faces are subtypes ofsash plates 9a now onthe market,

and obviously the rod 17 may be readily disconnected from the latch projection 14: so that the latch may be employed in the normal manner by operating the handle-portion 13 when the screen is not in use.

YVhile in the foregoing the'preferredembodiment of the invention has been described and shown, it is understood that the construction of the invention is susceptible tO;:Sl1Ch modifications as fall within the scope of the I appended claims.
