AIR-SUPPLY APPARATUS FOR SUBMABINE VESSELS.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed February 27, 1914. Serial No. 821,574.

To all whom it may concern:

Be it known that 1, PAUL PARNITZKY, a subject of the King of Hungary, and resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Air-Supply Apparatus for Submarine Vessels, of which the following is a specification.

The present invention relates to a submarine boat, and more particularly to means which insures a constant circulation of pure air in the living compartments of the vessel.

One of the objects of the present invention is to produce an air supply apparatus for submarine vessels which is simple in construction, efficient in operation, and that will permit the vessel to remain submerged for any desired time.

Another object of the invention is to produce an air supply apparatus that furnishes air to the vessel by the action of the water in which it is submerged, so that the vessel need not carry along an air supply or an air refreshing supply.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction Within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawing, which illustrates a side elevation, partly in section, of a submarine boat constructed in accordance with the present invention.

The vessel is constructed on the theory that sea water contains a certain amount of air, which can be liberated from the water when the latter is allowed to enter a vacuum or partial vacuum in the form of a spray.

Referring now more particularly to the drawings, the numeral 1 indicates the body or hull of the vessel and 2 the conning tower. The hull may be of any suitable construction. The other parts of the vessel, which do not relate directly to this invention, are

not described herein. The hull is divided by partitions 3 and 4 into three sections or compartments, that is a middle section 5, that forms the living compartments, a front or bow section 6 and a rear orstern section 7. The front and rear sections communicate through a tube 8, that is disposed, preferably, immediately above the keel of the boat. To the front or how compartment 6 leads a tube 9, having a flaring mouth 10 and terminating in a sprinkler 11 at its inner end, which is disposed within the said compartment. An opening 12 is provided 1n the partition 3 for accommodating a fan or similar device 13, that is mounted upon a shaft 14:, the latter being actuated in any suitable manner by the engine of the boat. The fan 13 is of the suction type, or more particularly it creates a partial vacuum in the compartment 6. Within the rear or stern compartment 7 is disposed a water pump 15, its suction pipe 16 terminating a suitable distance above the bottom of the said compartment, and its pressure pipe 17 leading through the wall thereof. It is obvious that the pump 15 may be disposed within the compartment 5 of the boat without departing from the invention. In the partition 4 is formed an opening 18, in which is located a fan 19, its shaft 20 being actuated in any suitable manner. The fan 19 is of the pressure type, it causing air to be delivered from the compartment 5 into the compartment 7. The exhaust pipe 21 of the motor of the boat leads into the compartment 7.

It is to be observed that the capacity of the pump 15 is such that it prevents the water from rising in the bow compartment 6 a substantial distance above the upper level of the connecting tube 8.

The operation of the device is as follows: The pump 15, and the fans 13 and 19 are put into operation before the vessel is submerged. As soon as the level of the water rises above the flaring mouth 10 of the tube 9, water enters the latter. The water so entering is sprayed as it is being discharged through the sprinkler 11 into the partial vacuum which exists in the bow compartment 6. This partial vacuum is created due to the fact that the fan 13 is continuously rotated, and thus causes air to move from the compartment 6 into the living compartment The air which is contained in the water is liberated due to the partial vacuum existing in the compartment 6, and is then sucked by the fan 13 into the compartment 5. The waterv that enters the compartment 6 flows through the tube 8 into the compartment 7 from which it is discharged through the pump 1-5. The fan 19 causes a flow of air into the compartment 7, whence it is caused, together with the products of combustion that enter the said compartment through the exhaust pipe 21, to flow through the pump tothe exterior of the vessel. It is to be noted that a valve maybe mounted in the pipe 9 to regulate the flow of water therethrough or to shut it off altogether, if necessary.

What I claim is 1. In a submarine boat, the combination with a body section, of two interconnected compartments, a water supply pipe leading to one of said end compartments provided with a sprinkler located within said coinpartment, a water' discharge pipe leading from the other one of said compartments, means for forcing the water from the last named compartment through said discharge pipe to the exterior of the boat, and means for causing air to flow from said first named compartment to said body section and from the latter to said second named compartment.

- 2. In a submarine boat, the combination with a body section, of a bow compartment, a stern, compartment connected with said bow compartment, a water supply pipe leading to said bow compartment provided with a sprinkler located therein, a water'discharge pipe leading from said stern compartment, a pump for discharging the water from said how compartment through said discharge pipe, and means for causing air to flow from said bow compartment into said body section and from the latter to said stern compartment.
