11 Claims. c1. 74-531 My invention'relates primarily to improvements in jalousie operators or the like although not limited thereto; and it is a continuation in part of my copending application Serial Number 573,241, filed March 22, 1956 and now abandoned. Briefly and generally stated, the invention aims to provide a device as characterized which (1) eliminates the necessity for gearing; (2) is simple, durable and inexpensive in construction while being highly efficient in operation; and (3) which embodies positive means for effectively locking the louvers or the like in adjusted position j. 1 L 1 Various other objects and advantages of my advance in the art will be readily understood and appreciated by those versed in the art-upon'reference to the accompany ing drawings which-illustrate two presently preferred examples of the invention:- It is to be understood, how ever, that the disclosures are to be taken" illustrative, rather than limitative, since my inventive concept is sus ceptible of other-mechanical expressions within the spirit and scope of the" subject matter claimed hereinafter.

In the drawings, wherein the same reference characters have been used to the designate the same parts wherever they appear throughout the several views- 1 'Fig. 1 is an inside elevation of a typical jalousie window, showing a device embodying the invention mounted at a conventional location on the jamb;

n p 2 bearing pin 7 between lever-carried bearing ears 3a.' The arm extension of lever 3 has a pivotal connection as at with the lower end of an upwardly extending link member 9 whose upper end is pivoted as at 12 to the usual louver control bar 11. Louver control bar 11 has j the conventional pivot connections 13 with the end flanges 14 of louvers 15. Thus, when the lever 3 is swung about pivot 4, 5 by handle 6 in the full line position of the latter (Fig. 3), the louvers 15 are rocked in unison through the intervening linkage 9 and bar 11.

-Fig. 2 shows the lever 3 as having a disk-form major portion 3b extending through the window jamb structure and (see- Figs. 3 and 4) through a slot 1b in the base flange of bracket 1. As indicated in Figs-3 and 5, the supporting ears 3a for handle pivot pin or bearing 7 are disposed adjacent the plane of the opposite side of bracket flange portion 1a from the disk-form major portion 3b of lever 3. The drawing also shows that the handlesuppo-rting ears 3a are carried by an edge of the disk portion 3b of lever 3 which is remote from the arm extension which carries the link-connecting pivot 10.

' The means for clamping the louvers 15 in a set position will now be described. In carrying out this phase of the invention, I provide a relatively stiff pressure plate 8 which is pivoted on the lever pivot 4, 5 at the opposite side of the bracket flange portion 1a from the major portion 312 of lever 3. The free end of pressure plate 8 extends between the lever-carried ears 3a so that it will be thereby swung with lever 3 and will always be in a position to be engaged by the cam end 6a of handle 6 when the latter is swung to the dotted line position of Fig. 3, which is the full line handle (6) position of Fig. 4. Engagement of cam 6a with pressure plate 8 locks the louvers 15 in a set position by so frictionally engaging pressure plate 8 with the bracket flange portion It: as to lock the handle-carrying lever 3 against movement. The reason for the semi-circular outline of bracket Fig; 2 is a vertical section of a typical jalousie, as

taken'on line 2-2 of Fig. l;

Referring" to the drawings by reference characters 3 turning toFig's. PSI-inclusive, it will be seen'that' louvers 15 are operated mantrally through lever member 3 whicli is*piyotally j eonnected by pin 4' andbushing 5 to the semi-circular xtension la ofjthe outstanding flange of an L br acket 1. The 'baseflange of L-bracke't 1 is an flange portion 3b is so that there will always be a bracket flange portion adjacent handle cam 6a and the underlying outer portion of pressure plate 8 to be engaged by thelatter. Pressure plate 8 constitutes a shiftable offset extension of bracket flange portion 1a. Thus, flange portion 121 need not be of such size as to marginally underlie cam 6a, and economy of metal is effected.

I Referring to the secon'd form of the invention illus trated in F igs. 69, inclusive, numeral 20 indicates end carriers for the glass louvers 21, which 'carriers are pivoted as at 22 to the window jamb structure 23 asindicated. "The louver carriers 20 have rearwardly extending arms 20a which are pivoted as at 24 to a vertically shiftable control bar 25 corresponding to the control bar 11 of Fig. 2.

Actuation of the control bar 25 is efiected by the link 27 which is pivoted to the control bar as indicated at 26 adjacent one end. The other end of link 27 is pivoted as at 28 to the lever extension 29 of the disk 30 which projects through the window jamb structure and through the slot 31 in the base flange 32a of the L-bracket 32' which is-generally similar to the bracket 1 of Figs. 1-5, inclusive. r

The bracket 32 is secured as at 33 to the jamb structure 23 andsaid L-bracket 32 has the outwardlyex tending flange 34 providing the arginally curved medial extension 34a "to which the disk 30 is. pivoted as indicated at 35. The lever-carrying disk 30 has, at is opposite edge from the lever 29, the extension 30a which chored to the jamb'structure at the window openingby I bolts 2, 2, and-the lever'3 is' fitte'd at one endwith a pivotally connected operating handle 6. ':..The'lever-bpertaing handle'6 provides'a camf6a at its inner. endand isipiv'oted inwardly thereof on'the extends rearwardly of the rear edge of the flange extension 34a of bracket flange 34. The disk extension 30a carries the spacedly opposed and laterally extending ears 36 which extend across the plane of flange extension 34a and pivotally support, as at 37, the inner end of the handle 38 at the opposite side of flange portion 34g 3 from disk 36. The handle 38 is preferably of plastic friction-like material and its cam-providing inner end 38a isadapted to swing as in Figs. 7 and 8 to lockingly engage the adjacent surface of flange portion 34a.

Thus, the handle 38 as shown, has a dual funtioninthat it functions as a locking member and alsov as an operating handle for the disk 30,, 29 as indicated in Fig. 6. It will be understood, as above indicated, thatafter the louvers have been appropriately adjusted. by manipulation of the handle 38 in the Fig. 6 position, it is swung about its pivot 37 as indicated in Figs. 7 and. 8-, so that the cam action inner end 38a will bear against the adjacent face of the bracket flange portion 34aso as to lock the lever 29 and disk 30 against. movement.

A modified form of the handle 38 is shown at 40 in Fig. 9 and provides cross-sectionally U-shaped major portion 41 into the outer end of which is fitted the friction block 42 which is held in place by a pivotpin such. as 37 (Fig. 8) and can be renewed when necessary so as to avoid replacing the entire handle due to wear at the cam action end thereof.
