The lock can, however, be released by the emergency key 66, which is somewhatlonger than the change key, and is bitted to engage and actuate the rearmost pin' tumbler 60 to lock the sleeve to the key plug and release it from the casing. On turning the emergency key in the lock, the` dead bolt can be retracted by the cam 63 in an obvious manner. During this operation, the lower tumbler cooperating with the thumb turn member is released frein its locking position bythe tumbler' connector 53 which depresses said tumbler and permits the wing on the thumb turn hub to be shifted from the notch 52 to the notch 5l."

My improved lock, as herein described, is very simple, compact and inexpensive, and is reliable and secure. The partsare comparatively few'in number,'can be readily made, and are not liable to get out of order.l

Various changes mayv be'made in the details of the construction without departing from the scope of the invention as defined in the claims.

That I claim is: p

l. In a lock, a case, a dead bolt therein,

a tumbler for said bolt ,carried thereby, aA

tumbler mounted on the case, operating means cooperating with the first tumbler,

and another operating means cooperating with the second tumbler.

3. In a lock, a case, a dead bolt therein, a tumbler for said bolt pivoted thereon a second tumbler for said bolt pivoted to the case, means for interconnecting said tumblers, and means for operating said tumblers.

-L In a lock, a case, a dead bolt therein, a tumbler pivoted on said bolt, a fence cooperating with said tumbler, means for actuating said tumbler, and arsecond tumbler pivoted to the case and connected with the first tumbler.

5. In a lock, a case, a dead bolt therein, a tumbler for said bolt carried thereby, a second tumbler for said bolt pivoted to the case, key mechanism for operating` one of said tumblers and protracting and retracting the bolt, and a thumb turn member for operatf ing the other tumbler and protracting and retracting the bolt.

6. In a lock, a case, a dead bolt therein, a tumbler for said bolt Vcarried thereby, a second tumbler for said bolt pivoted to the case, a thumb turn hub coperating with said second tumbler, and a cylinder lock mechanism coperating with the first turnbler.

7. In a lock, a case, a dead bolt therein,

a tumbler for said dead bolt carried thereby,'a cylinder lock cooperating with said ating in said cut out portion and having 4 a wing coacting with said gate, and a tumbler having notches to engage the wing of said hub. i

9. In a lock, a bolt having a shank with a cut out portion therein and a gate in said cut out portion having inclined sidewalls, a thumb turn hub having a wing coacting with said inclined wallsofl the gate indeadlocking the bolt, and means for holding the edge of the'wing in coperation with said inclined side walls.`

' l0. In a lock, a bolt having a shank with afcut out portion therein, and a gate in said cut out portion having inclined'side walls, a thumb turn hub having a wing coacting with said inclined walls of thev gate in deadlocking the bolt, and meansv for holding the edge of the wing in coperation with said inclined side walls, said means comprising a spring pressed tumbler having convergent notches to receive the wing.

l1. In a lock, a case, a dead bolt therein having talons vat the upper part, a tumbler pivoted on said bolt and having an operating projection disposed between said talons, key mechanism coperating with said projection and said talons, a fence cooperating with said tumbler, the lower part of the bolt shank having a cut away portion, a thumb turn hub operating in said cut away portion to advance and retract\ the bolt, a tumbler pivoted to the caseand cooperating with said thumb turn hub, and means for interconnecting said tumblers.v
