The headed bolt 11 extends through the pivot openings 12 and 18, as shown in Fig. 4, and its reduced threaded end enters the recess 19 and receives a nut 21. The intermediate portion of this pivoting and securing bolt 11 is adapted to be engaged by the notches 8 in the lever so that it also serves as a locking detent for the lever. The notched edge of the lever is forced toward this detent 11 by a suitable spring 22 which preferably consists of a coil arranged on a stud or post 23 depending from the underface of the rotary housing. ()ne end 24 of the spring is anchored against the inner face of the wall 13 and the other end 25; of the spring is preferably bent at right angles and carries a grooved roller 26 to engage the edge of the lever opposite to the one which is notched. The spring thus keeps the lever constantly under tension and coacts with the notches 8 and the detent in looking it in adjusted position. In order to prevent the pressure of the wind from forcing the notches 8 off of the bolt 11, the notches are formed at one side with undercut portions orseats 8 which insure a secure grip of the lever on the bolt.

As the lever is moved laterally against the tension of the spring to free it from the detent, it will'be seen that the housing 10 will rotate on the detent or pivot since the outer. slot 14 is just slightly larger than the lever and causes the housing to shift as the lever is moved. The inner slot or opening 15 in the wall of the housing is made sufficiently large to take care of the curvature and swing of the lever so that the window 3 magnbe opened to a ninety degree angle.

the window sill may be provided a catch 27 to be engaged by the free end of the lever when the sash is closed to hold the latter in that position.

In applying the device it is simply necessary to fasten the bracket .6 to the sash, to position the lever on the sill as shown in Fig. 1 when the sash is closed, to arrange the casing beneath the screen and recess the latter and to then fasten the casing and catch on the sill.

In operation, it is only necessary to grasp the lever with one hand and move'it laterally against the tension of the spring arm 25 to cause its notched edge to clear the detent- 11 and to then push or pull the lever longitud nally to swing the sash to the desired position. When the lever is released, the tension of the spring is exerted automatically to hold the lever in any desired adjustment but should the wind be strongert-han the tension of the spring and thus swing the sash in either direction, one of the notches in the lever will drop over the vdetent and thus lock the sash against further movement.

lit will be seen that the device is of simple, strong and durable construction, may be made at a minimum of cost, may be readily applied by unskilled persons and may be easily operated with one hand and without moving the fly screen. In the movement of the lever in adjusting the sash and by the force of the wind on the sash considerable strain is placed on the pivot bolt and detent but by constructing the base plate as set same time the rotary housing may turn easily as the lever shifts. I claim:

1. A casement window operating device comprising a lever having a curved end for attachment to a swinging window, a casing including an attaching base plate and a rotary housing thereon, the housing being of circular shape and having a surrounding depending wall formed with openings to receive the lever, the base plate having an upstanding circular rib to receive within it the depending wall of the housing and form a bearing therefor, a spring within the easing acting on the lever, and a pivot unit ng the housing to the base plate and holding the parts assembled when the device is not applied.

2. A casement window operating device comprising a lever having a curved end for attachment to a swinging window, a casing Including an attachlng base plate and a rotary housing thereon, the housing being circular and formed with a pivot opening at its center and with a surrounding depending wall formed with openings to receive the lever, the base plate being formed with an upstanding circular rib to receive within it the depending wall of the housing and form a bearing therefor, the base plate being also formed with a central ralsed portion having a pivot opening and havlng its upper surface in the plane of the top of said rib whereby the lever may slide on said portion and rib, a headed pivot bolt passed through the said pivot openings and having a threaded end in the recess formed by the 'raised central portion of the base plate, a nut in said recess engaged with the bolt to hold the parts assembled, and spring means in the casing acting on the lever.

In testimony whereof I have hereunto'set my hand. I
