SUBMARINE WITH BINS
A submarine which will sink or rise in the water at will, without onvard or backward motion, was (.says the Baily Mail") shown by Mr H. Almdloton, -ts inventor, in the swimming bath o£ the Northampton Institute, L.C., J '?f e ?tlj. It was only'a 7ft model, but it fully bore out the claims made for it. Air Middleton worked out the idea some time ago, but has now brought it to perfection. The submarine is provided with two “fins" on each side, as well as a propeller. No. rudder is wanted, as the nrooellor shaft can be turned at an angle, directing the boat to port or starboard. The fins consist of curved flexible metal plates, and. like the propeller, they are driven, by electric motors running from accumulators. The submarine model can be propelled by the motion of the fins alone, and it then appears exactly like some large fish swimming gracefully. By bending the fins into the correct p Station the boat goes under and travels at anv depth below the surface. There is no “porpoise” motion, as in so many actual submarines when running under water. The most interesting feature of the boat is its ability to “sink or swim.” It was loaded with weights, and sank to the bottom of the bath; then, the “fins” were set in correct motion for rising, and in a few seconds it had come direct to the surface of the water. By working the fins at a different angle the submarine sank like a stone. The whole of the movements were governed hy electricity.
