My'invention is directed to novel means and
to a novel device for manually operating, adjust

the louvers, only'a fragment of one of Which’is
f_»shown, and each of Vwhich louvers have their op-v
posite ends bent at right angles to form end wings
to regulate light, air, sunlight, wind, dust, etc.
It is an important object of my invention to
provide means for manually adjusting the same
to any one of a plurality of desired positions and
or mounting flanges. A fragment only »of one
of said -louvers is shown in Fig. 1.

pivoted louvers of a window awning, a pivotally
mounted pintle connected to and along one of
said louvers; a crank arm mounted on one end
of said pintle; a shaft adapted to be journalled
in a window frame and in a position spaced from '
said pintle; a crank lever on the outer end of
said shaft; a link having one end portion opera
ary-window frames of a building, theregular

awning frame is hingedly secured to the building
window frame by a plurality of hinges which are 15 having a separable operative connection -with
said crank lever whereby rotation of said shaft
sec-ured at suitably spaced apart points to one
will normally rock said pintle; a grippablevpiv
side member of the awning frame to permit the
ctal lever on the other end of said shaft; and
awning to be hinged into an outward position
releasable locking means mounted adjacent said
over the window. Such installations particularly
have the advantage of permitting convenient ac 20 grippable lever for selectively holding said lever
mechanism with a connecting link and a head
in desired positions, said separable operative con
nection between said link and said crank lever
providing for quick outward movement of said
window awning away from said crank lever of
said shaft to permit access to the window adja
cent to which said awning is mounted.
