LIFE-BOAT.

Application filed August s, 1916.

To all whom it may concern:

Be it known that I, HARRY FISHER, a subject of the British Dominions, residing at 12 Doris St, Kensington Rd, London, Eng land, have invented certain new and useful. Improvements in Life-Boats, of which the following is a specification.

My invention relates to that class of life boats which have a passenger car suspended within them which retains its horizontal position independent of any rolling action of its supporting body and is intended to be an improvement upon the life boat shown,

described and claimed in the British patent numbered 8570 which was accepted on the 6th day of November A. D. 1913.

The principal object of the invention is to provide a life boat with a passenger car suspended in such a manner that it always retains its upright position independent of any rolling action of its supporting body. The car equipped for the carriage of passengers has a suflicient buoyancy to support on the water when fully loaded the whole of its supporting body, should such body be swamped forward and aft and holed amidships below the water line thus losing its buoyant powers.

A further object of the invention is to provide a covering for the passengers within the car and in such a manner that a constant supply of fresh air is admitted to them direct from the bow or stern of the boat, or through openings on the beam of the boat.

-Doors are provided in the semi-circular covering over the waist of the boat to allow of ingress and egress from the car to the outside or vice versa.

Further objects of the invention will appear from an examination of the drawings, and the following description and claims:

The invention consists principally in the combination of a life boat, an oscillating passenger car arranged therein semi or threequarter circular bulkheads secured inside the boat and means for suspending the oscillating passenger car from these bulkheads substantially as hereinafter set forth.

The invention consists finally in the features, combinations. and details of construction hereinafter described and claimed.

Fig. III is an elevation of one of the part circular bulkheads from which the passenger car is suspended.

Fig. IV is an elevation of one of the inverted bulkheads or hoods, which are attached to the ends of the semi-circular covel'llg over the passenger car, one at either en Fig. V is a cross section of the boat at points where aventilating shaft is situated and an inlet pipe to the ballast tank.

Fig. VI is a ground plan of the ballast tanks and fuel tanks.

F 1g. VII is a cross section showing the end of the passenger car and the method of suspension.

Fig. VIII is a broken part of the side of the boat and the wall of the passenger car showing the friction wheel brake.

The principal object of my invention is to prov de a perfect life boat, one that will afford its passengers complete protection from exposure, a life boat that cannot sink or be submerged even if swamped forward and aft and holed amidships, a life, boat that shape of an ordinary boat, having the beam somewhat cylindrically shaped. This offers less resistance to the action of the sea as it offers no grip.

The bow and stern of the boat are opened to all weather conditions, this being essential in a life boat, to permit of persons bein picked up from the water who may not 111v? boarded the boat before it left the ship, or in the case of rescuing persons from a vessel in distress.

The improved life boat does not solely rely for its buoyancy on the supporting shell.

The waist of the boat cannot be swamped under sea conditions. itself to keep the boat well afloat if swamped forward and aft yet if by misadventure the waist of the boat should be stove in below the water line, the passenger car in itself is suflicient to support the whole of the outer structure, even should it be fully loaded and swamped, as sea water cannot enter the passenger car as it is protected overhead by a semicircular covering, carried from one gunwale to the other. The forward and after ends of the covering are fitted with inverted bulkheads or hoods, these protect the passenger car from end-on seas. The hoods do not lie close to the bulkheads from which the car is suspended. This space allows free access of air to the passenger car. This space may be enlarged and thus allow of passengers in the bow or stern entering the passenger car over the ends. To lnsure the permanent stability of the boat a ballast tank is provided at the keel, this automatically fills with water as soon as the boat touches the water and is automatically retained against any rolling action by the same device.

Having briefly described the objects aimed at to obtain a perfect life boat and for what purpose they are used reference will now be made to the numerals as shown on the drawings and the parts they refer to. 1 is the open how 2 is the floor line of the bow 2 is a tank beneath the floor for containing oil for calming purposes. 3 is a partial circular bulkhead from which the passenger car is suspended 4: is the inverted bulkhead or hood attached to the semicircular covering 43* are observation ports fitted to the hoods capable of being opened or shut as desired 5 is a swinging hinged flap attached to the lower end of the hood, this is to close the opening to the space between the two bulkheads 3 and 4. 6 is a hand rail running fore and aft the covering over the passenger car 7 are ventilating shafts, which lead from openings in the side of the boat or covering. These are just above water line at swamped and full loading point. Attached to the openings are casings or chutes led up inside the semicircular covering and attached thereto. These freely admit air to the car which is suspended from the bulkheads 3 by means of a cambered bar 8, the ends of which pass through the ends of the passenger car and have pivotally mounted on them a friction wheel 10 which runs freely on its axle and within a bearing ring 9 securely attached to the bulkhead 3. A boss or shoulder 8 is attached to the cambered bar 8 and butts up against the inside ends of the passenger car 11 to which it is securely attached. 12 are supporting stays, 12 is an upright secured to the cambered bar 8 and the lower This is sufficient in end bolted to a band partially encircling the passenger car. This method of suspension permits the car to be very lightly constructed as the central weight is taken by the cambered bar 8 by means of the upright 12 The stern of the boat 13 is entirely open to the weather and is fitted under seagoing conditions with the usual detailed seat lockers, steering gear, engines and all necessary appliances.

The ballast tank 15 is subdivided into compartments preferably one forward and one aft, these two contain the water ballast. The compartments amidships numbered 17 are for containing fuel for a motor. The water enters the ballast tank 15 by means of the pipes 16 which have one end open to the sea, the pipes being led across the bottom of the tank inside. By this automatic device, the ballast water is held in the tank, no rolling action of the boat being able to release it. Only when the boat is being lifted direct from the water on an even keel, as when being put aboard a ship can the ballast be released, this action being auto matic. 18 are the openings in the semicircular covering. These are fitted with slidably operated covers, 19 are the fuel feed pipes led from the fuel tanks 17 to the motor, being secured close in the angle formed by the tank and boats bottom. This affords complete protection to the pipes. 20 is an air escape from the ballast tank, this is to be carried well above the car. The lines at the bow and stern marked A and B show full load line at A with the boat swamped forward and aft and holed amidships. B is water line at full load with the boat clear of water inside the difference of the draft being approximately five inches.

Having thus described my invention I claim as new 1. A boat having its bow and stern open, two transverse bulkheads in segmental form erected at some distance apart, a semi-cylindrical covering securely attached to the gun wale and extending fore and aft beyond the said bulkheads, two inverted segmental bulkheads securely attached at each end of the semi-cylindrical covering and being placed a short distance respectively from the first named segmental bulkheads, there being a space between the upper surface of the first named bulkhead and the covering and also a space between the lower edge of the second named segmental bulkhead and the bottom of the boat substantially as set forth.

2. In a life boat an oscillating passenger car suspended from and between two bulkheads in the waist of a boat that has its bow and stern open to all weather substantially as and for the purpose set forth.

3. In a life boat, a cambered bar for suspending the passenger car from two bulkheads, fore and aft and athwartship stays, a boss, a friction axle roller,and bearing ring substantially as set forth.

4. In a life boat, an automatic ballasting tank attached to the keel of the boat, the ballast being automatically admitted to the tank, automatically retained in the tank and automatically emptied from the tank when required by the same device, including a pipe or pipes led through the tank from the 10 Water ballast, substantially as set forth and 15 shown in the drawings.
