a lication filed my a,

To all whom it Be. it known that I, Isaac L. LArrnR'rY, a citizen of the United States, residing at Fredonia, county of Wilson, and State of Kansas, have invented certain new and-useful Improvements in livotally-Mounted Glass Louvers, of which the following is a specification, reference being had tothe accompanying drawings, which form a part of this specification.

M invention relates to glass louvers for win ows or doors;

The object of my invention 1s to provide a glass louver, pivotally mounted and opera provide a translucent glass louver, that can shown in Figs. 1 and 2.

lieferring to the drawings, Fig. 1 is a front elevation, Fig. 2 is a detailed side view, parts being removed for convenience of illustrati'on; Fig. 3 is a detail "of the louver con 1 is the side casings of a window frame, 2 is the head casing, 3 is the stool, 4 is the apron, 5 is the window sill, 6 is the. head and side jambs, 7 is the stops engaging in the grooves of said jambs and against which the louvers will engage when closed as The said louvers each 9 grooved to receive the glass 8 and the said frame being U-shaped in construction, the rail 10 of which is rabbeted to receive the a top edge of the glass snugly of the louver next below making a weatherproof joint therewith. a

The said louver frame has trunnions 12 on each end thereof and in axial alignment with rail 10, the said trunnions function as pivotal bearings for each end of the louvers, engagin in apertures in the side jambs of the win ow frame, and one of said trunnions being of 'suilicient length to ass through the jamb and receive on the en thereof an arm 13, and the opposite end of said am bein pivotally connected to a vertically dispose bar 15, 16 is an operating lever pivotedly 1923. Serial No. 649,333.

connected to the bar 15, the said lever having an aperture 18 adapted to engage on one of the lower louver trunnions in operative relation with the arms 13. The opposite end ofsaid lever 16 is adapted toextend outward through the casing 1, engaging through a plate having a segmental slot 19, and the outward end-thereof functions as a handle for oscillating the bar 15 which is the medium by which the louvers are opened and closed, the upper edge following the dotted lines A as shown in Fig. 2. 20 is a coil spring positioned on the outwardly extending arm of the operating lever, said spring tensioning between pin B and a washer C,

said spring engaging said washer tofrictionally engage edges of the segmental slot 7 19, so that the louvers when partly opened will remain in such position by reason of the I tensioning means on the arm of the operating lever. I

Such modifications may be employed as lie within the scope of the appended claims,

and having thus described my invention,-

what I claim as new and desire to secure by Letters Patent is f In a pivotally mounted glass louver, the -combination of a frame and a plurality of U-shaped louver frames, said louver frames having a groove therein to receive a glass louver, glass louvers interposed within the grooves of said frames, a rabbet in rail 10 of said frames adapted to receive the upper edge of the glass of the adjacent louver, said .frames having trunnions in axial alignment with said frame portion 10, said trunnions have ametal frame engaging in apertures in the 'ambs of first said-frame, stops in parallel ignment with said apertures so that the ends of said louver frames will engage snugly thereon, arms rigidly mounted on the trunnions at one end of said jam from said louvers, an operating lever rigidly mounted on one'of saidtrunnions the end of which is pivotally connected of said -l ouvers, said arms and actuating .means be1n positioned on the opposite sideslot, all for the
