Change Yourself into a Fish 



Here's an invention that supplies every- 

 thing a man lacks to swim under water 



A one-man marine 

 suit which can 

 be used for salvag- 

 ing, life saving and 

 for wartime duty 



IF you know the story of the submarine 

 you will at once see the similiarity 

 between the invention illustrated and 

 the first submarine, built during the reign 

 of King James I. That old U-boat was 

 constructed of wood and was designed to 

 be propelled by oars extending out 

 through holes, the water being prevented 

 from coming in by goat skins tied about 

 the oars and nailed to the sides, to make a 

 watertight joint. In the one-man sub- 

 mersible described here, human arms take 

 the place of oars, rubber and steel sup- 

 plant goatskin and the propelling power 

 consists of two separate units, one for sur- 

 face and the other for underwater running, 

 such as we have in our modern submarines.

The propelling power consists of two separate units, one 

 of them for surface and the other for underwater swimming 



portion has its sides fitted with glass win- 

 dows and the bottom portion has a tele- 

 scoping window, so that the operator can 

 guide the vessel where he desires, lying in 

 a longitudinal position with his legs pro- 

 jecting out behind like the tail of a fish. 

 Directly above the shoulders of the opera- 

 tor is a gasoline engine connected with 

 a shaft which revolves the propeller. A 

 compressed air motor with a storage tank 

 takes up the space beneath the operator's 

 body and is to be used when the boat is 

 submerged. Collapsible tanks under his 

 arms correspond with the ballast tanks 

 of a submarine and water is taken in or 

 expelled according to whether it is de- 

 sired to rise or sink. Levers to operate 

 both engines are within convenient reach. 

 To work them, the operator must remove 

 one hand from its rubber sleeve. 



To supply air for the interior of the 

 shell when the boat is running on the sur- 

 face, floating-ball ventilators are provided 

 which automatically close when water 

 strikes them. The body portion of the 

 apparatus is fastened by straps to the 

 shoulders of the operator, so that he can 

 walk upright with it, or swim in any 

 direction — something no m.an can do with 

 an ordinary diver's equipment. The 

 boat in its present form weighs about one 

 hundred and twenty pounds, but for navi- 

 gating work at a depth of one hundred 

 feet or more, it would have to be very 

 much sturdier and heavier than it now is. 



The inventor 

 says it is possi- 

 ble to make his 

 boat the fastest 

 underwater 

 machine in 

 the world, 

 capable of 

 a speed of 

 forty miles 

 an hour, 

 with a radi- 

 us of action 

 of twenty 

 miles.
