Joined lo'ihe tnhnho: section is a section which extends from the boss 7 to wan-(l the iii: 'n cock 6, and coinnn'inicates "with :i seci'ion 18, which leads outward lln'ough an apeinn'e 01' poi-r 1?. The bent pipe made up of hhe end 9 21ml the sections 10 to H3 inclusive llHlF-E establishes communic: lion holwcen the inside of the boss 7 and innl; '1, and the outside of the some, and the object oi this hem; pipe is to permit the tank to he fillod with water when it is sunk iii be attached to the Wreck that is lo he mined.

The numeral 18 represents a Pomhiii' which leznls lo the simle of the holly oi the using 1 adjacent l'hc (h'oin cock (3, and the outer cool of ihisconihiiii is open to receive the eml oi a: eonclnit 1i 9 through which air "on he pumped into the-tool: "l. inside of the tank 1 the l inside of the boss nally in the opposite direction,

pumped it is bent as shown at 21 to extend again to-' ward the boss 7, and this section 21 is secured to the inside of the tank bymeans of a strap 22. At the end of the section 21 which is near" :t to the boss 7 the conduit 18 is bent toward its point of entry, as shown at 23, and then is again bent toward the y pumping out the water by the force of theboss 7 as shown at 24:. Adjacent the edge of the boss 7 this conduit is bent longitudinally, as shown at 25, and then longitudi- 26 extending substantially the aperture leading to the 7, and the length of the conduit 18 beyond the section 26 is returned on itself so as to extend in the same direction as the section 25, and then is bent down Ward, as shown at 27, into the boss, and then upward as shown at 28, reference being had to Fig. 2. The end 28 is of course open.

Expressed in another way, the air supply 26, this section along the edge of pipe within the tank 1 is composed of two parts, the first consisting of the portions 20, 21, 23 and2 l, forming oppositely-disposed connected S-shaped sections constituting a compound coil extending approximately transversely to the axis of the tank, and the second part consisting of the pornoises, 26, 27 and 28, forming an S-shaped section disposed approximately parallel to the axis of the tank and extending to opposite'sides of the boss 7.

In practice, the tanks are utilized by hav ing them secured in place under the water to the wrecks that are to be raised by the divers. When the tank is sunk it is con-" nected up to the air pumping apparatus, but no air is pumped into the same at this time. Instead the drain cock 6 will be opened and water will fiow into the interior of the tank through the port 17 and pipe connected thereto and terminating in the end 9 and the boss 7 so that the interior of the tank is filled with water, any air that may be trapped therein passing out through the drain cock 6, as will be readily understood. In this condition the tankcan be sunk to any depth, because the internal and external pressure of the water is balanced and there is no crushing stress exerted on the walls of the tank. When the diver reaches the wreck he fastens the rings 3 to the hulk thereof, preferably in horizontal position. Nhen the raising operations are to begin the drain cocks must be shut, and this is attended to by the diver after he fastens the tanks in place. Air is now down through the conduit 19 and into the conduit 18, and this air will be discharged into the boss .7 and pass through the open inner end of the same and the ionas shown at i 1 is connected in position by means of the rings 3, it will nbrmally remain in such position that the boss '7 will be below the same, and, if necessary, the diver .may-ho-ldit in such relation when the pumping operations forced drain cock 6 first being closed, the water gitudinal conduits 8, and force the Water in the tank out through'the port 17. These tanks can of course be made of any required size, and it is only necessary to connect a sufiicient number of them to a sunken wreck to raise the same to the surface.

The longitudinal conduits 8 which are connected to the sides of the boss 7 enable the water and air when they enter the tank a 1 to be more readily distributed, and the operation of filling the tank with water or incoming air can therefore be more readily and easily effected.

It will be understood that, when thetank begin. As soon as the air begins to be down through the conduit 18, the

inside of the tanks begins to flow out through the water port 17, and the air of course rises to the top of the tank. The water in the tank then acts as ballast to keep the same from revolving around on its side until all of the water in the tank has been discharged;

Nhen the tank 1 has once been filled with air it makes no difference what position it may assume, because of the manner in which the pipe terminating in the end 9 and leading to the water" port 17 is bent. In other words, so long as the drain cock remains closed and the airis not cut oli from the conduit 18, no water cah liow back into the tank. If the tank remains horizontal, with the boss 7 lowermost, of course the pressure of the air inside of the same will be exerted upon the surface of the water in the boss 7, as long as the level of the water in this boss remams gust about at the end of the pipe 9. Should it turn 'nto vertical position, with either end uppel most, the air pressure will be exerted down upon the surface of the water in the section 10 or the section 14, as the case may be, to check the inflow. Or

should, for any reason, it be turned so that the section 15, the slant of the section 15 being made suilicient for this purpose; and should the tank ever cometo such a position that the drain cock 6 would point downward and the boss 7 upward, water would in this till claim as new and desire to roemoe:

case also be prevented from entering. This feature of my invention is very important, as sunken hullis do not always remain on an even keel when they are raised, but may roll to some extent. ltis ojt course unlikely that they will ever roll so as toniove the tanks into all. or any one of the extreme positions which I have mentioned. Consequently, the tank l have devised never becomes re-tilled with water when the water hos once heen pumped on; of the some, so as to cause the vessel to sink to the bottom otter the reisi ug operations have been begun, unde any conditions met with in actual practice.

From the manner in which the conduit 18 bent on the inside of the tankfil, it will be econ that similar effects are secured. When the tank is being sunk down to be put in position by the diver, no matter in what position he may take the some, that is, whether .ie takes it vertically with either end upward, or horizontally, with any part of the tank facing downward, there will elways he a certain length of that portion of the conduit 18 which is inside of the tank through which the water must pass in an upward direction to till this conduit. In such a section it will be subjected to a downard action of the air PIQSSUI'Q and stopped, end it will be understood that this result will follow for any depth.

From the above description it will be seen th: t l have devised an improvement in buoyancy tanks which is eziccedingl simple in its construction and therefore can be readil and cheaply made, and which is also exceec ingly etlicient in use' lVhen being taken down to be attached to a wreck by a diver, the water inside. of the tank balances the pressure of the water outside of the tank, and no crushing stress is exerted at any time upon the device. Furthermore, when the water in the tank is pumped out or forced out by the pressure of the incoming air, this air pressure performs the some function as the water it is displacing, namely, it balances the external pressure on the :mteide of the tank and eliminates the crushing force of the water just as el'lfecti'vely.

My buoyancy tank can be used of course with submarine boats on account of the (52 with which the some can be tilled with water and emptied. lhulcr: any coudit' ms of work i can either discharge the o' tirely therefrom or only in pert. way i ran regz'ulute lhelnioyunt eii cct of my invention so as to be able to keep eulr marine boat in a. condition of stable r-quililr riuin at any. depth when my tanks used .l'or sohn'mrine navigation.
