The casopening 27 of a configuration best shown in Figure ing 6 has its closed end provided with a tubular 2 and having a spring receiving enlargement l28 11g at one side thereof, the bolt being positioned in the recess 27 with its locking end 26 normally yieldably projected beyond the peripheral surface of the barrel by a spring 29 confined between the bottom 30 of the spring receiving enlargement 28 and a laterally off-set arm 31 on the locking bolt. A pin 32 yanchored in the barrel and a projection or tit 33 on the transverse arm 31 serves to maintain the spring in its proper relation.

The innermost end of the locking boltA has an elongated opening 34 through which a pin 35, anchored in the inner closed end portion 15 of the barrel, extends, to secure the locking bolt against outward displacement by the spring while permitting the same to be `depressed andV swung about the pin 35 as a pivot. It is noted that the tendency of the spring 29 is to swing the locking bolt about its retainingpin 35 in a counterclockwisedirection, with respect to Figure 2, to align its outer locking end 26 with the transversely offset extension 25 of the keeper recess, thus automatically engaging the locking bolt with the off-'- set' portion 25 whenever the movable lock unit is lmoved` inwardly into its mounting unit sufficientlyY far vto bring `the bolt in alignment there- Disengage'rnent of the locking bolt from the offset portion 25-to permit movement of the movable lockfunit to unlocked position is accomplished by vturningpthe lock cylinder 14. The cylinder 14 is rotatably mounted in the bore 36 of the barrel and is secured against longitudinal movement therein s? :med in the inner end of the lock cylinder.

As is customary, the cylinder 14 is provided .'withj a plurality of locking tumblers 41 which are Vldable urged to engagement with one of a pair or'longitudinalgrooves 42 formed on the barrel nl communication with its bore 36, the tumblers being retractible within the peripheral surface of the cylinder to `free the cylinder for rotation upon the insertion of a proper key 43.

At the extreme inner end of the lock cylinder isan eccentrically located driving cam 44 which is adapted to engage the side of the locking bolt opposite its spring 29, and upon rotation of the lock cylinder imparted thereby through the medium` of the'key 43, rock thelocking vbolt about its retaining pin 35 against the action of its A lspring 29 in a clockwise direction withlrespect to lFig-ure 2, and thus disengage its` locking end 26 f'froin the transversely off-,set portion 25 of the e keeper recess.

Upon Abeing disengaged from the transversely off-set portion 25, the locking end 26 of the bolt yis, aligned with the elongatedlongitudinal portion 24 of the keeper recess to free the movable lock unit for outward movement by the expansive 1springp19. Such outward movement of the mov- .able lock' unit is limited by the engagement of the end'` 26 ofthe bolt'with the outermostr end 45 of the elongated longitudinal -portion 24 of the keeper'recess. The movement of the movable A.lock unit in the performance of its normal locking functions is thus dened by the lengthof the longitudinal portion 24 of the keeper recess.

If? it'is desired to remove the movable lock unit Yfromits mounting unit those authorized to do so may effect such removal by merely inserting `a. suitable tool 46 into an opening 47 in the outer casing 6, which, being aligned with the Vcylinder 14 to be withdrawn from its barrel 13.

During insertion of the movable unit in its mounting member, it is only necessary to initially depress the locking bolt until it is moved into thebore 12 of the inner shell and to continue the inward movement of the movable unit until the bolt snaps into the off-set portion 25 of the keeper recess.

From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art to which an invention of the character described, appertains, that I provide a lock structure having a novel manner of readily removably securing the movable unit in itsmounting structure, wherein -ing functions, but also provides depressible means for readily removably securingy the elements assembled.
