Abstract A safe for protecting valuables such as jewelry with an outer casing having an open top and an inner casing for receiving the valuables. A hydraulically operated, mechanical linkage within the outer casing mounts the inner casing for movement by the application of hydraulic force between a lower and elevated position. First and second locks are disposed in the hydraulic path which elevates the inner casing and each include a rotatable annular element and a second element rotatable therein, each element having a passage therethrough so that the hydraulic elevating path is completed when the passages are aligned by choice of the correct combination. At least one of the elements includes a drain path for releasing the hydraulic pressure to lower the inner casing. An alarm coupled to the hydraulic path sounds whenever pressure greater than a given value is detected indicating that pump has been operated without the locks being in the correct positions.
A safe for protecting valuables comprising: an outer casing having an open top, an inner casing for receiving said valuables, a linkage means within said outer casing for mounting said inner casing within said outer casing for movement between a lower, protected position within said outer case and a stable elevated position permitting entry into said inner casing, hydraulic means mounted within said outer casing and connected to said linkage means and defining a first hydraulic path for applying a force to elevate said inner casing to said elevated position and a second path permitting said inner casing to return to said lower position, a source of hydraulic fluid within said outer casing and connected to said hydraulic means for supplying hydraulic fluid under pressure to said hydraulic means, and first and second locks each includng a first rotatable and annular element and a second element rotatable within said first element and having a dial for rotating the same, each element having a first passage therethrough so that when said elements are rotated to a rise position in which said first passages are aligned whereby a first path is completed to elevate said inner casing and at least one of said element having an oil drain passage so that, when said one element is rotated to a lower position, the oil pressure is released and said inner case is lowered.
