11 Claims. (01. 15614) My invention relates to window screens and struct the screen and sash operator as one commore particularly to a means mounted entirely plete and compact unit whereby this unit may be upon a screen frame and which may be detacheasily applied to a sash frame and the operator ably connected to an associated window sash thereafter may be quickly attached to the sash by whereby to serve as an operator for the sash. means of a readily detachable connection.

screen itself whereby the disadvantages above The turret is drilled and tap at 16 t0 TeceiVe a headed locking bolt 17 which may be rotated llll Fig. 5.

whereby the bolt will engage and lock the operator 7 in any desired position after its adjustment. A sash connector head 18 is pivotally mounted as at 19 upon the outer reduced end of the operator which engages within a slot 26 formed in the head. A bracket 21 is attached to the lower rail of the sash 5 and a downturned hook 22 is formed as a struck-out portion of the bracket 21. The hook is adapted to engage within a slot 23 formed in the head 18, which head is preferably tubular in cross-section and having the slot 23 formed in the lower bottom wall of the head.

The rail 10 is slotted at 25 to receive the casing 9 and permit the operator to swing angularly through the slot. The flanges 26 provided on the rear end of the casing 9 may be welded to the rail 10 whereby the casing and screen rail 10 become an integral unit. It will be noted in Figs. '7 and 8 that an appreciable length of the operator 7 is housed within the casing 9. It will be noted also that the screen is provided with a skirt like flange extension 27 which projects rearwardly from the screen frame. The main screen frame and the extension 27 affords an appreciable depth to the screen frame whereby the connecting link 18 may be completely housed within the plane of the screen frame when the screen is closed against the frame 2.

In operation, with the screen and sash in their closed position, when it is desired to open the sash, the latter is first unlocked from the frame 2. The locking bolt 17 is rotated to release the operator '7 and the latter is then rotated clockwise and pushed outwardly until the sash has reached an intermediate or an extreme position under control by the operator. With the screen and sash connected by the operator, the screen may be unlocked from the frame 2 and the screen, sash, and operator may be swung fore and aft as a unit about the respective hinges. If it is desired to open the screen or sash, or either of them, to their maximum opening, the screen and sash are swung inwardly until ones arm can be extended in rear of the screen in order to grasp the connecting head 18 which may then be lowered slightly whereby to release the hook 22 from the slot 23. The screen and attached operator may then be swung inwardly as far as desired and the sash may be swung outwardly as far as desired. This feature of operation permits a full opening through the casement frame and affords a decided advantage in that a clear passage to the exterior of the building is obtained in a manner to permit cleaning the windows or for operation of awnings.

, Another-advantage secured by supporting the operator upon the screen frame is that it allows the sash and thereafter both screen and sash may be'moved to their full open position as shown in In this figure, a hinge is shown which permits an appreciable gap between the sash and frame in the open position of the sash whereby,

with the screen in its fullopen position as shown H and the operator disconnected from the sash, an unobstructed access may be had to both sides of the sash for cleaning the same.

of the frame 2, while the head 18 is positioned within the plane of the screen frame. In effect,

the inner end of the operator bar 7 and the head 18 constitute a toggle arrangement affording an efiicient leverage and this toggle is mounted within the casing 9 and the adjacent space between the side bars of the screen frame in a manner to permit the screen to be positioned closely adjacent the sash.

While I have shown a preferred form and arrangement of my invention for the purpose of illustration, it is to be understood that various modifications thereof are contemplated as will be embraced within the scope of the claims which follow.

I claim:

1. A screen comprising a frame member, means for pivotally connecting said member to a casement frame, a sash operator, a casing supported on said member, and means for slidably and rotatably securing said operator within said casing to provide a unitary screen and operator unit.

2. A screen comprising a frame member, means on said member for pivotally connecting said member to a casement frame, said member having an opening therethrough, a sash operator extending through said opening, a bracket secured to said frame member adjacent said opening, means on said bracket displaced from said member and providing a fulcrum for pivotally supporting said operator in a position parallel to the member.

3. A screen comprising a frame member, a sash operator pivotally supported entirely upon said member, means for pivotally connecting said frame member to a casement frame, said member having a slot therethrough, said operator being movable through said slot and means for its iio

connecting said operator to a sash whereby the 7 screen, sash and operator may swing as a unit, or said sash may be operated independently by said operator said frame member and operator being removable from the easement frame as a unit. 7

4;. A screen comprising a frame, a casing integrally attached to said frame, a sash operator rotatably secured to said casing with one end of the operator extending within the casing, means for connecting said end to a sash said operator 7 being movable to a position close to said frame and parallel thereto.

5. A screen comprising a'frame member, a sash frame, said frame member and sash frame being pivotally connected together, a sash operator adustably mounted on said frame member, said member being provided'with an opening, a sash connecting link pivotally connected to said operator and being operably movable through the opening, a flange extension on said frame member adapted to contact the sash frame when the screen is closed, said link being housed within the plane containing the frame member and flange extension when the screen member is closed against the sash frame.

for connecting said member to a casement frame, a sash operator, and fulcrum means on said member for supporting said operator upon the member, said fulcrum means permitting the operator to move to a position parallel to the member and means for pivotally connecting one end of said operator to a fixed point on a sash.

7. A screen including a frame member, said frame member having hinge means for side attachment to a casement frame, a sash operator, said member being provided with an opening, a

- casing permanently attached within said openoperator to a fixed point on a sash, said operator being movable to a position parallel to the frame member with the inner end of the operator housed within the casing.

9. A screen as set forth in claim 8, wherein the fulcrum point of the operator is positioned adjacent one side of the casing.

10. A screen as set forth in claim 8, wherein the operator is slidably and. rotatably mounted within the casing.

11. A screen comprising a frame member, said member having an opening therethrough, a bracket secured to said member opposite to said opening, a sash operator slidably and rotatably mounted on said bracket, a link connected to the inner end of the operator and having means at its free end for attachment to a sash, the fulcrum point of said operator being displaced from said frame member whereby the operator may be positioned parallel to said frame member.
