The above mentioned mountings constitute but
one element of the device. According to the in

provide a marine platform suitable for revictual

If we assume such a platform as above de
scribed, being supported by'its buoyant rollers F
on the surface of the water, the side beams of
the frame C may perform either a tilting, swing

the beams D are mounted on the tie bars 3 or
