The element 99 comprises vertical'cylinder |00 having its bottom formed with an axial opening IDI and a depending collar |02 surrounding the latter. The cylinder |00 is open at its upper end. The deck 8 is formed with an opening |03 to the wall of which is anchored the upper end of cylinder |00. A spring controlled cover |04, hinged to deck 8, is provided for normally closing the upper end of the cylinder I00.- The cover is hinged to deck 8, as at |05, and has an upstanding lip |06 engageable by a pivoted latch |06a for releasably retaining the cover I 04 in position to close the upper end of` cylinder I 00. The latch |06a is pivoted, as at |01, to deck 8 and carries a depending operating handle |08 which passes through an opening |09 in deck 8. Suitable resilient sealing means is arranged in opening |09 and through which passes handle |08. Pivotally connected to the cover |04, as at ||0, is a spring controlled pull member I I for quickly pulling cover |04 open when the latch IIlEiL is moved to release the cover.` The member includes a curved outer part ||2 and a straight inner part ||3. The member passes through an opening I|4 formed in deck 8. Suitable resilient sealing means is arranged in opening ||4 and through which passes the member I I I. Anchored at its lower end, as at 6 with the vessel is a controlling spring ||1 for member II The lower end of part |I3 of member is connected to the upper end of spring II1, as at IIB. The cover |04 is shifted to closing position relative to cylinder |00 and latched in such position against the action of spring I I1. Arranged within the cylinder |00 is a set of spaced parallel expelling springs ||9 for the element 68. The springs H9 are anchored at their lower ends, as at |20, to the upper face of the bottom of cylinder |00. The upper ends of springs ||9 are anchored, as at |2|, to the lower face of a follower plate |22 formed with an axial opening |23.

At this` point nthe circuit for the ,lamps will `be closed whereby the signals will be made active, magnet 8| energized and the bolt 92 shifted to release the spring 93 to provide for the projecting of the antenna to above the lamps. In the meantime, the line I6 will have been opened and the compressed air supplied to the lifting elements. If the compressed air from the tank is not suflicient to completely ll the lifting elements to project the sections 29 of these latter, the compressor will be thrown into operation to supply the necessary additional compressed air. When the sections 29 of the lifting elements have been extended to their outermost position, the lifting elements will then act to raise the submerged or sunken vessel to the water level.
