Cool.
Looks like he pioneered the use of clear plastic tubing for watertight cylinders. I wonder if some of his subs survive today.
some modern flying RC subs or diving RC planes.

Excerpt from the patent describing the operation of his RC submarine's ballast system
The operation of this radio controlled model submarine is quite entertaining, amusing and instructing. When ready to sail the model submarine air is first removed by deflating the inflatable members 126 by Submerging the submarine in water to the conning tower level. Drawing out the air may be hastened by using a rubber tube and drawing in air by the mouth thus deflating the inflatable member 126. Of course, the timer 148 must be in an open position. Then, the balloon 172 in the conning tower 32 is in flated so as to regulate the depth to which the submarine will submerge. This step is empirically tested by inflat ing the balloon 172 varying amounts as may be desired so that water will not enter the breather or snorkle tube 54 through which the antenna conduit extends. The balloon 72 may be then closed using the closure mem ber 176. It is not necessary to use excessive pressure on the balloon 172. When ready to launch the submarine the timer 48 may be held in the open position and the inflatable member 26 may be inflated by detaching the conduit i46 and blowing into the inflatable member 126 by use of the breath or by any other suitable means. The submarine may then be placed on the water and engine and radio switch turned on with the timer 148 opened to full position for timing to shut off. As the ship travels through water air slowly leaves from the pump and ballast tank through the timer air escape unit valve i68 and the sub slowly sinks to near the top of the conning tower level as was previously adjusted leav ing snorkle tube 54 exposed. The timer finally snaps to the off position stopping the air escape and causing the air pump to inflate the ballast tank drawing air in through snorkle tube 54, it being noted that the selected depth to which the sub marine will submerge will not immerse the snorkle tube 54. The pump is of course normally operating upon operation of the motor. This causes the submarine to re Surface back to normal exposed running position with deck and Superstructure again visible above the surface of the water.Make it simple, make strong, make it work!Comment
