The tanks are further errg nged with expansion heads so that theyiney at all times be kept withouhsleck fluid ecting on the Walls of the banks The tanks are of such dimensions that they will provide such capacity as will be sinncien'bto allow the vessel to carry her hotel deedyveight ofoil, but it may also be arranged iao carry part of the oil in the exhallast tanks of any such vessel.

Ti lie method of securing the tanks is by Wedge sheped pieces running vertically be tween the isnks or between eaclrtenk and ship side or bulkhead. Each pair of upright is connected by bolhs, the screwup 0 any set of Whichacting both as supp to the tanks sides and securing the two ienks thus connected together, and also ngg the tanks to the ships side or bulkhead; in short making a combination be tween all tanks and the ships side and hulk-v he fl but the connection being only frictional and not permanently binding any of the parts. i

Said drums'are all connected with pipelines,

I tiguous drums, between the drums and the "shi -s sides, and between the drums and the bu heads. Bolts, as j, unite each pairof wedges, and on being tightened up, thereby ra wing the wedges together, serve to 'frictionally connect the drumsone with ana j: other and to the ships sides and bulkheads;

[whereby said drums become positively stabilized' within the compartments of the hold.

other contingency to be provided against is thatof the interference ofhold stanchions,-.

To -this end I may, for example, place a vertical post as Z within .a'drum between the head and-bottom thereof'and in position thereinwliensaid drum is adjusted mlplaoe, to be. in alinement with the verti-' cal line of said interfering'st anchion.

Obviously under the arran ement described my improved system 9 removable tanks for steamships, or other vessels) for the shipment of oil and other fluid in. ulk, is applicable either to vessels of ordinary construction, inwhich case the oil tanks will be designed to be of suitable dimensions to .occupy the hold or compartment space afforded, or both vessel and removable I o-1l tanks may be especially designed to serve the purpose of economizing space. Withal, the main factors prevai mg are those of the convertibility" of an ordinary freighter into an 'oil tank f-vessel and back into an ordinary freightemthe vessel maintaining its 'normal strength and stability under both conditions, and, as a tankshi where, the oil retaining parts are not sub jected to strain due to working'of vessel.

I claim:

1. In a convertible a freighter and tank "vessel, a ships hold, a number of removable cylindrical tanks vertically placed therein; and adjustable means connecting said tanks together and to the sides of the hold.

2. In a convertible freighter and -tank I vessel, havin water tight compartments, with bulkheads, a number of vertical cylindrical tanks. removably placed therein, and pairs of wedges fitting-between adjacent surfaces of said tanks, compartment sides vessel, aships hold, anumber of cylindrical.

tanks vertically and rcmovably fitted therein, a tank 'occupyingtlie position of a di s.

placed stanchion, and 1a post within said tankto support the stanchion strains.
