3 Claims. (Cl. 268--23) The invention relates to jalousie windows and has more particular reference to the operating means and also the means for holding the sections in any positlon of adjustment thereof. The invention, therefore, consists in the construction for such purpose as more full hereinafter set forth.

In the accompanying drawings:

Fig. 1 is an elevation of a portion of a jalousie viewed from the inside and in which my improvements are incorporated.

Fig. 2 is a section on line 22, Fig. 1.

Fig. 3 is a section on line 33, Fig. 1.

As specifically shown, the jalousie is incorporated in a door and includes a supporting frame extending across the space between the stiles. This frame has side members A which extend longitudinally of and are secured to the stiles B. The rockable sections C of the jalousie are pivotally secured to the said side members to hold the glass strips in overlapping relation to each other when in closed position. Each of these sections C have a rock arm C and all of said rock arms are pivoted to a common connecting bar D which is located in a vertical channel within said side member. To actuate these rockable sections and also to hold them in any position of adjustment thereof, I have provided the following construction. E is an angle member which is located in the corner between the stile B and the inwardly projecting portion of the frame member A being rigidly secured in this position by screws or other fastening means. E is a casing integral with the member E and having at its inner end a portion E of smaller external diameter extending through an aperture A in the frame A and forming a shoulder bearing against said frame. Such casing E constitutes a bearing for a rotatable member F which latter extends through the bearing and the aperture A in the member A to the channel within said member where it is attached to a crank arm G. A connecting rod H pivotally attached to this crank arm extends longitudinally of the channel and at its opposite end is pivotally attached to the common connecting bar D. At its outer end the member F is attached to an actuating rock arm or handle I by which it may be rotated to move the section C from closed to open position. However, it is desirable that these sections in any position of adjustment thereof should be held against accidental displacement. This is accomplished by forming the member F of two sections F and F The section F is cup-shaped to receive the coil spring J which surrounds a pin K having a threaded engagement with the section F The pin K has at its outer end a head K which has a projecting cross rib or tongue K engaging a groove 1' in the member I. At the outer end of the member F is a head F which contacts the end of the bearing E and this head is bifurcated as at F to receive the arm I between the furcations thereof. A pivot pin I connects said arm to said furcations. The member F is conical and engages a corresponding conical surface E in the bearing E. With the construction as just described ice frictional contact with the corresponding conical face E of the bearing E'. This friction will be suflicient to hold the member F from turning in its bearing and'there- I by holding the crank G and rod H from movement.

These, in turn, will hold the jalousie sections from movement. When, however, it is desired to adjust these sections it is only necessary to rock the member I inward on its pivot I which will compress the spring I and will move the member P out of frictional engagement with the face E The member I may then be rocked about the axis of the member F to adjust the jalousie sections to any desired position. Upon releasing the handle I, the spring I will instantly move the conical face of the member F into frictional contact with the face E which will lock the parts from further move- 1. An operator for jalousie windows provided with a Y supporting frame, comprising an open ended casing member mounted on and extending through an aperture in the supporting frame, said casing being interiorly cylindrical in its outer end portion and flaring to form a conical seat in its inner end portion, a crank arm for operating the jalousie windows having a projecting conical portion about its axis fitting within said flaring conical seat portion, a cup member fitting within said cylindrical portion and having an outer enlarged bifurcated head portion bearing against the outer end of said casing, a headed rod within said cup member passing through a central aperture therein into threaded engagement with said conical portion, a coil spring sleeved on said rod abutting against the head thereof and said cup member to resiliently press saidconical portion into frictional engagement with said conical seat and to normally hold said crank arm from movement, an actuating rock arm pivotally connected to said bifurcated head between the furcations thereof and bearing against and non-rotatively connected to said headed rod, whereby pressure of said rock arm against said headed rod will release said conical portion from frictional engagement with said conical seat and permit rocking of said conical portion and crank arm to operate the jalousie windows, said spring automatically relocking the jalousie windows when said rock arm is released.

2. The construction as in claim 1 in which said casing has its inner end portion of smaller external diameter extending through the aperture in the frame and forming a shoulder bearing against said frame.

3. An operator for jalousie windows provided with a supporting frame, comprising an open ended casing mounted on and extending through an aperture in the supporting frame, said casing being interiorly cylindrical in its outer end portion and being flared in its inner end portion to form a conical seat, a rotatable member in said casing and having two sections, one having a cup-shaped portion fitting within said cylindrical portion and provided with an outer enlarged bifurcated head portion bearing against the outer end of said casing, the other having a conical portion fitting within said flaring seat portion, a crank arm for operating the jalousie windows secured to said conical portion, a rod extending axially through said cup-shaped portion and connected to said conical portion, a coil spring within said cup-shaped portion and sleeved on said rod, a wall of said cup-shaped portion forming an abutment for one end of said spring, an abutment for the other end of said spring carried by said rod, said spring cooperating with said abutments and said rod Patented Sept. 4, 1956 3 4 to forc'e said conical portion into frictional'en'gagernent the conical portion into frictional engagement with said with said conical seat and thereby normally hold said conical seat to hold said crank arm and jalousie windows crank arm from movement, an operating rock arm pivagainst movement when said rock arm is released. otally connected to said bifurcated head portion between the furcations thereof and having a tongue and groove 5 R fere e Ci i h fil of i patent engagement with said.rod, whereby pressure of said operating rock arm against said rod will release said conical UNITED STATES PATENTS portion from frictional engagementwith said conical seat 2,119,710 Holder June 7, 1938 and permit rocking of said conical portion and crank arm 2,5 81,321 Fletcher J an. 1, 1952 to operate the jalousie windows, said spring cooperating 10 2,605,648 Sanderlin et al Aug. 5, 1952 with said abutments and said rod to automatically return
