Lock assembly 30 includes a combination lock 24, an operating arm 35 enabled to turn when combination lock 24 is open, and a pair of live bolts 25 linked together for movement by arm 35 between locked and unlocked positions. A pair of dead bolts 19 arranged on an inner wall of cabinet 20 opposite live bolts 25 cooperate with lock assembly 30 in holding deposit box 50 securely in place. Opposite ends of the deposit box have internal steel channels 54 and 55 enclosing recesses into which the live and dead bolts enter through apertures 60 in the side walls of box 50. When locked, live bolts 25 pin together lock assembly 30, a crossbar 16 at the back of cabinet 20, and deposit box 50, making the system highly resistant to attack. ## Claims ### Claim 1 A wall safe comprising: a. a steel cabinet sized for mounting flush within a wall; b. said cabinet being formed with a frame around an open front; c. a crossbar anchored within a rear region of said cabinet and extending along a line dividing said cabinet into a lock region and a box region; d. a lock assembly enclosed within said cabinet in said lock region; e. a deposit box removably lockable within said cabinet in said box region; f. said lock assembly comprising a combination lock, an operating arm enabled to turn when said combination lock is open, and a pair of live bolts linked together for movement by said arm between locked and unlocked positions; g. said crossbar having a pair of holes registered with said live bolts, so that when said live bolts are in said locked position, said live bolts extend through said holes to lock said live bolts and said lock assembly to said cabinet; h. a pair of dead bolts arranged on an inner wall of said cabinet opposite said live bolts; i. opposite ends of said deposit box having steel channels enclosing recesses within said deposit box; and j. outer walls at opposite ends of said deposit box having bolt receiving apertures opening into said channels, said apertures being arranged so that said deposit box can be placed in said box region of said cabinet where said dead bolts extend through a pair of said apertures and into said channels, and said deposit box can be locked in place by moving said live bolts through said crossbar and through another pair of said apertures into said channels. ### Claim 2 (depends on 1) The wall safe of claim 1 wherein said deposit box closely fits within said box region of said cabinet and has an inclined surface confronting said lock assembly and oriented to allow tilted placement of said deposit box onto said dead bolts and pivotal movement of said deposit box against the rear of said cabinet while said inclined surface moves adjacent said lock assembly. ### Claim 3 (depends on 2) The wall safe of claim 2 wherein said apertures for receiving said live bolts are formed in said inclined surface of said deposit box. ### Claim 4 (depends on 3) The wall safe of claim 3 including a carrying handle arranged on said deposit box adjacent said inclined surface and disposed forward of said lock assembly when said deposit box is locked in place. ### Claim 5 (depends on 1) The wall safe of claim 1 wherein said deposit box has a cover with a lock, said cover is disposed against the rear of said cabinet when said deposit box is locked in place, one of said channels within said deposit box has a locking slot, and said lock for said cover of said deposit box locks into said slot in said channel. ### Claim 6 (depends on 1) The wall safe of claim 1 wherein said operating arm for said lock assembly is turned by a key fitting a lock or said arm. ### Claim 7 (depends on 6) The wall safe of claim 6 wherein said deposit box has a cover with a lock, said cover is disposed against the rear of said cabinet when said deposit box is locked in place, one of said channels within said deposit box has a locking slot, said lock for said cover of said deposit box locks into said slot in said channel, and said key for said operating arm lock also fits said lock for said cover of said deposit box. ### Claim 8 (depends on 1) The wall safe of claim 1 including means for securing said lock assembly to said crossbar, supporting tabs of said lock assembly interlocking with said cabinet opposite said support bar, and guides for said live bolts mounted on said lock assembly and disposed adjacent said crossbar. ### Claim 9 (depends on 8) The wall safe of claim 8 wherein said deposit box closely fits within said box region of said cabinet and has an inclined surface confronting said lock assembly and oriented to allow tilted placement of said deposit box onto said dead bolts and pivotal movement of said deposit box against the rear of said cabinet while said inclined surface moves adjacent said lock assembly. ### Claim 10 (depends on 9) The wall safe of claim 9 wherein said deposit box has a cover with a lock, said cover is disposed against the rear of said cabinet when said deposit box is locked in place, one of said channels within said deposit box has a locking slot, and said lock for said cover of said deposit box locks into said slot in said channel. ### Claim 11 (depends on 10) The wall safe of claim 10 wherein said apertures for receiving said live bolts are formed in said inclined surface of said deposit box and including a carrying handle arranged on said deposit box adjacent said inclined surface and disposed forward of said lock assembly when said deposit box is locked in place. ### Claim 12 (depends on 11) The wall safe of claim 11 wheein said operating arm for said lock assembly is turned by a key fitting a lock for said arm, and said key for said operating arm lock also fits said lock for said cover of said deposit box.
