In view of the Eutherford clock, the watch- man's time detector, and, indeed, the clocks and watehes which are commonly in use, the improvement seems to me to have been so obviously and plainly a mechanical one, that it is unnecessary to dwell upon this part of the case. �The Sargent invention, being re-issue No. 7,947, consisted, in the language of the specification — " Third, in the combi- nation, with the boit work of a safe or vault door, of a combi- nation lock, controUable mechanieally from the exterior of said door, with a time lock controUable automatically for unlocking by the operation of its time mechanism ; both of said locks arranged to control the locking and unlocking of the boit work, so that said safe or vault door cannot be opened when locked until both of said locks have been unlocked, or released their dogging action to enable the door to be opened, substantially as hereinafter described." �The patentee further says : "The combination and arrange- ment of the time lockwill be more fully hereinafter described; but it is evident that any form or construction of a time lock may be used as a part constituting one element of the com- bination called for in my claims.

Therefore such locks are not a safeguard against robbery. Clock locks have also been used upon safe or vault doors for the purpose of opening the door at a pre- determined hour, thus placing it beyond the power of any ��� �
