Abstract
Abstract An adjustable combination lock key safe includes telescoping inner and outer stamped sheet metal cylinders, the outer of which releasably carries a U-bolt shackle for securing the key safe to a mounting member such as a door knob and the inner of which carries locking means adapted to lockingly engage the shackle and outer cylinder to thereby maintain a secured relationship therebetween, the inner cylinder including a storage area for retaining contents such as a key or other desired limited access articles and having a multiple disc combination lock with an outer knob and dial for effecting release of the locking means and an inner adjustable dial for changing the combination of the lock whereby the key depositor may select a unique combination so as to provide limited access to the key safe for use of the contents therewithin.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
An adjustable combination lock safe which can be set to a plurality of discrete lock combinations to provide limited and variable access thereto comprising: telescoping inner and outer members defining in assembly relationship a compartment adapted to secure contents therewithin; shackle means releasably carried by the outer member for retaining the safe on a mounting member; first lock means carried by the inner member adapted to be actuated to lockingly engage the shackle means to prevent separation thereof; actuating means carried by the inner member operable upon telescopic insertion into the outer member to actuate the first lock means to effect locking engagement with the shackle means; second lock means lockingly engagable between the inner and outer members to prevent telescopic separation thereof; adjustable combination lock means operatively connected to the second lock means for unlocking the latter upon dialing a predetermined changeable code to permit separation of the members and thereby provide access to the contents therewithin.
Claim 2
Dependent Claim
