The operatlng device Bcomprises a frame :or base section 5 in the form of a plate which is rigidly secured'to the door A by screws or equivalent fastenings 6 and which has a circular flange 7Q Infront of the base or back section 5 is a rotatable plate 8 which turns one central stud oripivot 9 screwed into a central boss 10 on'the back section; 5,- and on this front section or plate 8 are fixed 5 pins 11 which extend into the chamber 12 and engage in elongated openings 13 in the :ofiset ends 14 of the locking bolts 1 and 2, "which latter enter the casing of the locking device throughuopenings 15- in the circum-i ferentialflange On the stud 9swings an operating handle 16 which has avlost motion connection with the plate or disk 8, by reason of a pair of screws 17 and 18, which screwhinto the under side of the handle and are engaged respectively in slots 17 and 18. in the disk 8. The head of the screw 17 is countersunk in the disk 8 and :the slot 18? for the screw 18 islocated in anextension 19 in one edge of of this extension are spaced lugs 20 which are adapted to engage the bosses 21 on the base 7 section to limit the swinging movement of the handle 16, asclearly shown in Fig.6.,

a The 7 lost motion between the handle and the bolt-throwing plate 8 is utilized for the ignate double doors, the new door being normally locked by head an'd foot bolts 1, and 2 actuated by an operating device B and movable in guides 3 to engage keepers lat -10 the plate or disk 8:; On the under side throwingni to nd out ofwoperatio of? ies meansfor preventing the? belt if rom being bpei'ated frein eithrextrern'e position,
