This invention relates to easement window actuating mechanism foriopening andclosing such a window and for holding the same in any position to which it may be swung'.

An object of the invention is the provision of such mechanism which is simple and inexpensive to manufacture, easy to manipulate, efficient in operation, unlikely to get out of order and inconspicuous in apearance.

The following is av description of a casement window actua-ting mechanism embodying the invention in its present preferred.

form but it will be understood that various modifications andchanges may be made therein without departing from the vspirit of the invention and without exceeding lthe scope of the claims.

The invention will best be understood by reference to the accompanying drawings, wherein itis illustrated in its present preferred form, and in which 1 is a' fragmentary `elevation of a window casing and sill "defining a window opening in which are installed a hinged screen and a caserne-nt window to which latter the invention has been applied; Fig. 2 shows altransverse section of the casing, screen frame, screen netting and Casement window, and, in plan, thewin- Vdow sill and the Casement window actuating mechanism embodying the invention, f the window and the device being indicated in the closed position by solid lines, and, in an open position, by dotted linesfthe handle for actuating the mechanism being also shown in dotted lines; Fig.vr 3 is a fragmentary detail on a somewhat largervscal'e, show ing a portion ofthe screen frame, of the window frame and of the glass mounted in the latter, and also showing,-in Vtop plan, a portion of the window sill, with a portion of the device installed therein and with.v the coa'cting portions in operative position--one pore tion of the device being removed to more clearly disclose the structural details; Fig. 4i;v

is a topplan of the device installed position in the window sill and upon .the frame ofthe easement window, said view being gen? erally similar to that of Fig. 3, but with the lever element which was removed from.. 3 restored inpar'tjand'in part broken away to show the'structural details; Fig. 5 is a sec` tion' of Vthe device on the'line 5 5 of Fig. 3, looking in the direction of the arrows; Fig. 6 is a fragmentary detail on the line 6-6 of Fig., 3, looking in the direction of the ar-` rows; and Fig. 7 is a fragmentary detail on the line-7 7 of Fig. 3.

Like reference characters indicate like parts throughout the drawings.

Referring to the drawings 1 and 2 indi` cate side members ofla window casing, and 3 indicatesa window sill. Mounted in theinnerside of the window openingis a hinged screen` comprising a frame et and a netting 5. Y

Mounted in the outer side of the window opening is a Casement window, comprising a frame 6 and a pane of glass 7 the windowy being supported upon j hinges such as V8. Mounted ina recess formed inthe window sill 3 near one end of said sill and disposed in a substantially central position with refverence to the vertical plane of the screen is s Seated in the recess 10 is an` annular disk 18.

A second lever 19 cooperates with the lever 12 ina" manner to be hereinafter described. rlhis lever 19, has an oii'set, disk-shaped portion 20 which serves as a cover for recess 10.

A bolt 21 axially disposed with reference to recess. 1() passes through a central aperture formed in the. disk-shaped portion 20 of lever 19, through the elongated aperture 14 of .lever12, through a central `aperture in annulary disk 18: and through' a central aperture in thelbottfom` wall of recess 10. A washer 22anda nut 23 co-operate with the bolt to maintain :the levers and the annular disk in position. :An aperture 24, formed in the Adiskshapedportion 20 of lever-.19, and an aperture 25, formed in they annular disk 18,

serve as aseatv fora cylindrical lever-shift,-

' ing element 26, preferably provided with a Surrounding screw 31 is tubular spacingl member 33; and similarly surroundingscrew 32 is a like tubular spacing member 34. These spacing members serve toV maintain the relative positionsof lever 19 and annular disk 18, and also restrict undue deflection of spring`35. vMounted in annular disk 18 are pins 36' and 37, serving as stops to limit the movement of lever 12 relative to said disk.

Formed in the outer end of lever 12 is elongated aperture 38; and formed in the outer endv of lever 19'is a circular aperture, 39. The outer ends of the two levers are operatively ield between the jaws of a slidable element, 40, being maintained therein bya bolt 41, passing through said jaws and the aforesaid aper-` tures formed in the levers. Three sides of this slidable element 4() contact with correspondingl sides of a square shaft 42, supported between brackets 43 and 44 attached to the lower member of easement window frame 6. Supported by a pin 45 between the jaws of slid- Y. able element is a friction shoe, 46, which its position of contact with friction shoe 46, A,6,0

ts loosely on said pin 45, whereby it can be brought into intimate contact with the front side of the square shaft 42 to create friction therebetween.

The mode of operation of the device is as follows: With the easement window closed, the urge of spring 35 forces the outer end of lever 12 against the friction shoe 46, the wedge Y action therebetween causing said friction shoe to bind against the front face ofsquare shaft 42 thereby locking the window in place.

Under this condition the positions of the respective parts are as shown in Fig. 3. Levershifting element 26 is provided with lugs 47 and 48, adapted respectively to engage lugs 16 and 17 of the arm portion 13 of lever 12. When it is desired to open t-he window, the

Asquare end of handle 28 (indicated by dotted lines in Figs. 2 and 4) is inserted inthe square socket 27 of lever-shifting element 26. The application of pressure to the handle in a clockwise direction first slightly rotateslevershifting element 26 about its axis, bringing lug 48 intoengagement with lug 17 of the arm iortion 13 of lever 12.I in the manner shown in Fig. 4. Lever 12 is thereby retracted from leaving slidable element 40 free to move-along square shaft 42. Further pressure applied to the handle 28 causes the disk-shaped portion of lever 12, together with its associated elements, to rotate in the recess 10 about the axis of bolt 21. This causes slidableelement element 26 is shown in solid lines in the position which it occupies when the window is closed; and in dotted lines in the position to which it andthe handle 28 have been moved in the process 'of swinging the window 90 to the position indicated by the dotted lines.

It will be understood that, regardless of the position ofthe window, whenever pressure on ythe handle 28is released, the spring 35 again urges lever 12 into wedging contact with friction show 40, and thereby locks the window against movement in either direction. It will be further understood that, when it is desired to .close the window, the handle 28 is swung in a counter-clockwise direction,

whereby-lug 47 engages lug 16, releasing` the contact between the frictional shoe 46 and the face of the square shaft 42 and permitting the slidableelement 40 to move freely along said square shaft.

, As appears from Figs. 1, 2 and 3, the device is inconspicuous, being normally concealed in the space between the lower member of screen frame 4 and the lower .member of window frame 6. No parts of the device protrude either intothe room or out of doors. Less than half the plate 9 is visible, and, because of its being iush, its appearance is not objectionable. The handle 28 may be permanently attached or det-ached and conveniently suspended from a' hook on the face or edge of the window casing, where it ordinarily will be concealed by draperies. The invention possesses the further advantages that it is unnecessary in installing it to cut through the screen frame, as is the case with certain i the easement window is vautomatically locked l in any position to which it may be swung; and the leverage applicable by means of the handle is ample to render the opening and closing of the window an easy task for a person of ordinary strength.
