SHIP.

Specication of Letters Patent.

Patented Dec. 1, 1914.

Application led May 1, 1912. Serial No. 694,487.

To all whom t may concern Be it known that I, ROBERT SMTTH CLIFT, master mariner, of Montreal, Province of Quebec, Dominion of Canada, have invented certain newV and useful Improvements in Ships; and I do hereby declare that the following is a full,` clear, and exact description of the same.

This invention relates more particularly to the providing of a ship with life saving means for use in case of shipwreck and it has for an object to provide an improved form of releasable or detachable float or pontoon'or compartment constituting part of `boat under normal conditions and adapted to be easily loosened from the hull in the event of accident.

For further comprehension of the invention and of the objects and advantages thereof reference will be had to the following description and appended claims, and to the accompanying drawings forming part of this specification inV which similar reference characters indicate the same parts and wherein- Figure 1 is a plan view of the after portion of a vessel having the invention embodied therein. Fig. 2 is a longitudinal section view thereof, and Fig. 3 isa transverse section taken on the line 3 3 Fig. 2.

In the drawings the after part of the hull of a ship is shown at 1, the propeller and rudder being shown at 2 and 3 respectively. According to my invention the upper portion of the said rear part of the hull is constructed to form a compartment separate and releasable from the rest of the vessel and which may be termed a pontoon or float and which extends the full width of the vessel and whose interior forms a compartment adapted to receive the crew and passengers in case of accident. This float or pontoon is shown at 4 and has a bottom 5, side walls 6 and front and rear walls 7 and 8 respectively, the bottom and walls being joined to form a water tight structure. The'v length of the pontoon proportionately to the hull may vary but I prefer to make it about one-eighth the length of thehull.

As shown in the drawing the pontoon is supported upon the second to topy deck 9 ofthe ship with the top 10 of the pontoon constituting ythe top deck` of the after portion of the ship, while the sides and rear of the pontoon conform in outline to the hull of the vessel. v i

The bottom 5 of the pontoon is preferably spaced slightly apart from the deck 9 by suitable means such as the channel irons v11 secured upon the deck 9 and extending transversely thereacross, and on which irons the bottom '5 of the pontoon rests freely. The purpose of this spacingis to allow for washing out and lcleaning and also to permit of oil or' the like being poured in under the pontoon to keepv the deck from rusting or corroding, andV to provide an airspace to facilitate the floating of the pontoon inV the event of accident. The pontoon is retained against lateral displacement by carrying up, as at l2, the vupper plate of the hull on either side to overlap the lower edges of the pontoon. i'

The walls and top of the pontoon are constructed of the usual hull forming material, the weight of all but the'bottom ones of the plates forming the sides of the pontoon being preferably the same as that of the plates forming the hull (including the overlapping plates 12) while the bottom of the pontoon and thelower side plates thereof are preferably reinforced or of double thickness, this construction being provided in order that, should the vessel before sinking take an abnormal .list to one side the weight of the pontoon will break ofin the plates 12 and allow the pontoon to slide laterally linto the water, the reinforcing of the bottom and floor plates ofthe pontoon insuring the giving way of the side overlapping plates 12 Vwhich lare weaker.

In theembodiment of the invention illustrated in the drawings the pontoon is arranged to haveits top flush with' and forming the rear portion of the main deck of the vessel andthe front end abuts against a bulkhead l5 extending completely and unbroken across the vessel between decks, access tothe pontoon being entirely from the top as willbe presently Vset forth, a slight air spacel indicatedv at 15 being left between the pontoon and bulkhead to prevent `any chance of suction interfering with the floatingof the pontoon.

Suitable releasable devices are provided for locking the pontoon against rearward displacement.- As here shown .one or more y arms 16 are pivoted at one end to stanchions 17 secured upon the deck of the ship adjacent the forward end of the pontoon and are adapted to be swung down between the lugs of a pair of forked standards 18 upon the pontoon, while locking pins 19 may be inserted through suitable registering perforations in the standards and arm. A second arm 2O is pivoted upon the upper end of a link 21 pivoted in turn at its lower end to a bracket 29 upon the stern of the hull just below the deck 9. This arm 20 is adapted to swing down between the lugs of a pair of forked standards Q3, similar to the standards 1S, upon the rear of the top 10 of the pontoon, to which standards the arm is locked by pins 2li similar to the pins 19. Although not shown in the drawings similar locking devices may be provided at the sides to reinforce the side plates 12.

rlfhe details of the interior arrangements and fitting of such pontoon and the manner of access thereto may of course be varied to suit individual requirements but l will describe the arrangement preferred b y me.

The pontoon is provided with a double bottom 25 forming a space in which fresh water is carried, this space preferably being divided into several compartments by vertical partitions 26. The water contained in. the double bottom is intended for drinking purposes for the people in the pontoon when the latter has been detached from a sinking vessel, the pontoon being provided with a suitable pump, not necessary here to be shown, which may be connected to any one of the compartments in the double bottom.

Access to the interior is had through a pair of raised hatchways 28 from which stairways 29 lead into the interior of the pontoon while steps-30 also lead from the deck l0 to the tops of the hatches, which latter may be provided with hinged covers 3i. A water tight bulkhead or partition 32 provided with a suitable door preferably extends across the pontoon near the end therec the deck 10 of the pontoon.

of forming a compartment in which may be stored sails, fuel, lamps, rope and hand pump, while another bulkhead preferably extends across the pontoon between the hatches. Along the sides of the pontoon may be arranged lockers indicated at 83 adapted to contain supplies of provisions while above such lockers are provided bunks 3-1 for sleeping accommodation. The pontoon may also be provided with a heater or heaters 35. As shown at 36 mast sockets are also preferably secured to the fore parts of the hatchways while a boat, masts, gafs and rigging (not shown) may be carried upon To admit of light entering the pontoon when the hatches are closed deck dead lights (not shown) of very thick glass may be provided. y s i ln event ot' accident to the ship the arms 16 and Q0 will be released, the passengers and crew will enter the pontoon, the hatch covers will be closed and as the vessel sinks the pontoon floats ofi'.

lf desired, to contend with weather conditions, masts can be fitted in the sockets 36 and sails set.

With my improved device the deck space of the vessel is not in any way obstructed while the pontoon under ordinary conditions forms part of the ships hull and passengers may be accommodated therein, or it may be used for mail and postal rooms.

lli/hat l claim is as follows:

1. A vessel having a removable pontoon or floatresting on one deck thereof and having a false bottom, the sides of the hull of the vessel overlapping and engaging the sides of the pontoon, being carried up above the lowermost level of the pontoon and terminating below the level of the false bottom.

2. A vessel having a removable pontoon or float resting on one deck thereof and having a false bottom, the sides of thehull of the vessel overlapping and engaging the sides of the pontoon, being carried up above the lowermost level of the pontoon and terminating below the level of the false bottom, the sides of the pontoon increasing in thickness downwardly from the false bottom and being of greater thickness than the overlapping sides of the hull.

3. ln a vessel the upper deck of which terminates at a point spaced from the rear of the vessel to expose a second deck, transversely extending supports secured to the second deck, a. pontoon resting loosely upon the supports, the top of the pontoon being substantially on a level with the top deck and the outlines of such pontoon conforming to those of the hull of the vessel, means at the front of the pontoon for securing the latter in place comprising an arm pivoted to the top deck, extending over and being detachably secured to the top of the pontoon and securing means at the rear of the pontoon comprising a link pivoted to the hull below the second deck, extending up to near the top of the pontoon and an arm, one end of which is pivoted to the upper end of the link and the opposite end detachably secured to the top of the pontoon.

t. ln a vessel the upper deck of which terminates at a point spaced from the rear of the vessel to expose a second deck, transversely extending supports secured to the second deck, a pontoon resting loosely upon the supports and having a false bottom, the top ofthe pontoon being substantially on a level with the top deck and the outlines of such pontoon conforming to those of the false bottom, means at the front of the pontoon for securing the latter in place comprising an arm pvoted to the top deck, eX- tending over and being detachably secured to the top of the pontoon and securing means at the rear of the pontoon comprising ay link pvotecl'to the hull below the second deck, extending up to near the top of the pontoon and an arm, one end of which is pivoted to 10 the upper end of the link and the opposite end detachably secured to the top of the pontoon.
