Mr Walter Paddon ( ex-chief engineer of the merchant service who lives at Bayswater in London ) claims that he can save the lives of every member of the crew in a submarine disaster - he has constructed a model of a submarine in wood - it is two feet long with a baby submarine a quarter of its size is in a floating dock on its deck - Mr Paddon calls his invention Paddon's Detachable Safety Chamber - he says it would enable a crew of 100 men to leave a sunken submarine and come to the surface quite dry within 15 minutes - as soon as a submarine was sinking and orders were given that it was unable to rise the crew would leave the parent ship by an airlock with doors at each end - as soon as they had all passed into the smaller boat the door to the airlock would be closed and bolted - Jack screws would then free the baby submarine from the floating dock and it would rise by its own buoyancy with the crew in it - this method would be more expedient than the Davis apparatus where each man left separately - photo shows Mr Walter Paddon and his model March 20th 1934
