This invention relates "to improvements in locks es useci upon swinging doors of various types, Where ed iii-ate promotion 1S desired, the lock being of the cylinder clues.

One of the objects of the invention is wore-ride a ice-l1 having a plurality of hell, elements, in piece of a single holt as usually employecl one or more of which may engage with ihe threshold or casing oi the door at points remote from the lock, trans rersclv to bile main. horizontal halt.

Anofiher object is to provide tumblers which cenno b be damaged by iiifieinpis ii:- riliina into ihen'n "whereby they may he OKQGd RIHl the lock opened nnentiiorizeclljg.

Another ohi'eci; is to provide means wiicrel'w doe lock may he operated from the inner side of ihe door, irrespective of the (J-Ol'Mll'iTiOn off the tmnhler herreh anii finally in "provide means whereby should the her-- rel. stem he removed by iorce or otherwise, that the lioite would; still ren'iziin in. ii locked position end in which. it is impossible to i-c-edjnst the operative perks from the. on torior of? the eloor. 1

These and other ohjecis are :it-teinedl by the novel adaptation, combination incl constri. ion oil ports hcrcinniter riescriberi and shown in the cccoinpanfng (herring form-- ins" material part of this specification, end. in hiich: I

Within the casing are two slidzible bolt elements LG and 18, connected. by a rigid integral bar 17, the bolts being guided by the recessed member 19, formed with a. fixed stop at its inner end. Also formed with the bolt 18 is :i resii'ivardly extending :irin 622 having rack teeth 23, the some engaging); with the teeth on the elongated pin.- ion 2 3: mounted to rotate freely Within the casing 14: flIHl provided with n stein which extends outwardly beyond locli. casing 15 and has pinned to it ii lcnnrlcci knob 26 by which it may he rotated. lhe pinion is held. normallyagiiinsi; the inner cover 28 of the loci: by means of tee coilccl push spring which :ihutsnt one enol c ains the pinion 52 i, curl at the other against the iiangcil extension 30 of the casing 15. Elm gngcii with. the pinion 9A rack 32 con- 152 for is disposed upon ,necleci by e rod 33,to the cylindrical holl;

49 between the pins and rods are in register with the periphery of the cylinder 48.

At the rear end of the cylinder l8 is a rectangular stem 50, and engaged with the stem is a'rectangular bar 51 formed with'a slot 52 and clamped by the bolt 53, a teetangular enlargement 54: extending into an opening 55 formed in the pinion 24', the enlargement terminating in apin 56, revoluble in the bearing 57 formed in the pinion and by which it is maintained normally in aline- 'ment with the key barrel. Should the tumbler barrel be removed as by force or other-. wise, and the pin 56, together with the driver 54 be withdrawn from the pinion, the lat-.

' use, what I claim as new and desire to secure by Letters Patent, is

1. In a lock of the class described, thecombination with a casing, a bolt movable horizontally therein, said bolt having two spaced extending elements, a vertically movable bolt. means for actuating said bolts simultaneously, said means being operated by a knob upon one side and by a key on the other, means for disengaging said key'operatedmeans from said actuating means and means for preventing reengagement of said I actuating means. i

2. In a lock of the class described, the combination with a casing, bolts movable therein, and a rack combined therewith, of a pinion engaging said racks revoluble in said casing, said pinion being inclinablypaounted, a knob for actuating said pinion,'a key barrel havinghardened pins operative therein, a cylinder rotatable within said barrel,.

an adjustable connection between said cylinder and said pinion, said connection having a part normally maintaining said pinion in a horizontal position and, means preventing the reinserti0n of said part after withdrawal.

3. In a lock of the class described, a casing, one or more bolts slidable' in transverse planes in. said casing, racks combined with said bolts, a pinion common to all of said racks, direct means for rotating said pinion on one side of the lock, a key operated rotating means on the other, a pivot mounting for one end of said pinion, an extension from said key operating means entering said pinion at the other, and means, operative upon the withdrawal of said extension, for raising said pinion out of alinement therewith and preventing its retntrance.

In testimony whereof I have signed my name to this specification.
