596,473. Latch handles. WILMOTBREEDEN, Ltd., and HARRIS, R. July 26, 1945, No. 19202. [Class 44] The outside handle f of a door is adapted to be retracted into a recess e so as to be flush with the door and retained by a spring-pressed catch r engaging the handle boss i, the handle being in this position disengaged from the latchactuating spindle g ; on withdrawal of the catch r by means of push-button q, the boss i is ejected by a spring j, a square-bored part n of the boss then engaging a correspondingly shaped part g<2> of the spindle to render the outer handle operative. Outward axial motion of the boss is limited by a collar k on the spindle. Rotation of the boss i when in the inner position is prevented by a feather connection o with the fixed boss a. The inside handle h being mounted on part g<1> of the spindle, to which the latch mechanism (not shown) may be connected, is operative in both positions of the outer handle. The spring j abuts a collar u on the spindle separated from a fixed plate v by a spring washer n. The push-button q has a wedge-like extension t engaging the edge of a hole in the catch r. The push-button q may be formed as a barrel-type lock which may be operated by a key so as to turn the extension t into a position wherein it can slide through the hole in the catch r without operating the catch.
