CHARLES I. NIELSEN, WEEHAWKEN, NEW JERSEY Application led December 20, 1929-. 'Serial No. 415,375.

vide the lifeboat with two mast-s and with an engine and with means for controllingthe engine and the sails and the steering from a single position, namely, a control cockpit.

Y A further object of my invention is to provide. within the bulkheads a sealed compartment for the engine, a cabin for small children and a toilet compartment.

It is a further object of my invention to 2c supply disappearing housing hooks on the lifeboat so that once the weight of the boat has been removed from the hooks there will be no chance for the tackle blocks which support the lifeboat to rehook.

2a For a more complete exposition of my invention reference may be had to the annexed drawings and specification at the end whereof -my invention will be fully pointed out and claimed. a

eo In the drawings,

Figure l represents an elevation showing the lifeboat under sail.

Figure 2 is a plan View, one half in horizontal cross section.

Figure 3 is a vertical cross section.

Figure 4 is a horizontal cross section taken at point below the tank deck or cellular under body of boat showing the entire buoyancy tank or cellular system'.

4o* Y Figure 5 is a vertical transverse cross section taken from directly in front of the control cockpit or other bulkhead.

Figures 6, 7 and 8 are, respectively, plan and side elevations of my improved housing hook.

Figure 9 is a partial horizontal cross section of a modified form of lifeboat -suitable for warships. l y

Figure l0 is a vertical cross section of the V-inodiiication shown in Figure 9.

My improved lifeboat has a hull built ofv any suitable materialand will be a staunch, able, seaworthy boat designed inl compliance with the U. SfSteam Ship Inspectors Rules i and' Regulations as prescribed. by law. I lTo 55' give the lower body-extra weight or to, in other words, hold the center of gravity down as low as possible a system of ballast tanks as shown in Figures 8: and 5` are-located inthe central partof the boat directly over the '60 keel. These tanks will'haveaV pipe connection leading vout-thI-oughthe bottomof the boat and ay small air' tube leading up to the tank deck for therelease of the air inl the tanks; 'sthe boat `immerges into the water 65-k these tanks will; all iill automatically t'o the water line of the boat and act as or constitute the ballast, tending tokeep theboat always v on an even keel. f V

In the main andcentral partof the boat, 7o

as willrbe" noted on Figures 3 and; 4', are located: a number of largeY size pipes thatfex.-l tendy from well deck or tank top deck down through: the bottomV of the vboat and will be made with the usual iiood valves.4 pipesrareused-` for automatic bailing of the boat inl a. heavy seawa'y and. will. also prevent the boat from going down by suction of a sinking vessel on which the lifeboat is' carried, as these pipes relieve any vacuum from the Se` bottom of the boat. 1

The hull is also dividedl into compartments by water-tightv bulkheads. The forward bulkhea'd':separates a forward compartment',

7 from the remainder of the hulll N ear the: e5

stern of the boat thereis provided a watertight bulkhead 8 which cooperates with lon.-y gitudinal bulkheads 9v and` l0 (see Figure l)r to provide..threercompa'rtments'11, 12 and 13 in thestern. rIhe compartment l2, which; 90'

is the center one, contains the motor 14 and. also anv oxygen tank 15. I'f desired, means for starting the motor may be arranged soy as to project from the central compartmentthrough a waterstight bushing. The central 95 body of the hullr between the' bulkheads and. 8 is adapted to contain alarge number of variously shaped tanks 16 which givebuoyancy tothe boat. In caseof injury the water Will enterthe main or'cent-ralp'artof 10U These p the boat, then and at no other time will these tanks come into play for buoyancy and it is for just such cases that these tanks are placed there. Above these air tanks is arranged the horizontal deck 17 which supports a tank top deck 18 which in turn supports wearing strip floors 88. Above the deck 18 is arranged a series of transverse seats 19. Convenient to certain of the seats 19 on the gunnels are oarlocks 20.

At the fore andaft po-rtions of the boat are arranged hoisting hook housings 21 which are connected to the frame work of the hull by reenforcing members 22.

Housings 21 are adapted to contain hoisting hooks 23 of an improved design. Hooks 23 carry at the rear parts thereof counterweights 24, which, when the weight of the boat is removed from the hooks 23 cause the hooks to fall into position within the housings 21 and to assume the dotted line position shown in Figure 8. In this position hooks 23 are caught by latches 25 which are pressed by springs 25 and which latch hooks 23 in such a position that the tackle-blocks cannot rehook on the hooks 23.

The upper portion of compartment 12 is provided with a water-tight manhole 26 whereby the compartment is carefully sealed and the motor 14 protected against Water. At the rear of the boat there is also provided a control cockpit 26 convenient to which is located steering wheel 27 which controls rudder 28 through a system of shafting and gearing 129. Adjacent to control tower 26 is also provided lever 29 for controlling the connection of motor 14 with the propeller 30 so that the propeller may be actuated to drive the boat either forward or backward.

There is also provided in the central portion o the boat masts 31 and 32 which are iitted into convenient mast chests 33 and 34 so as to be readily raised even by persons unfamiliar with sails and boats. Mast 31 is provided with a fore staysail 35 and a schooner rigged foresail 36 and mast 32 is provided with a schooner rigged sail 37. Sails 35, 36 and 37 are provided with convenient tackle for manipulating them. The halyards 38 for sail 37 are conveniently located to control tower 26.

The forward compartment 7 contains bread tank 39, fuel oil tank 40 and a pair of buoyancy tanks 41 located, respectively, beneath tanks 39 and 40.

Compartment 11 is intended as a shelter for children or the most feeble members of the occupants of the boat. Compartment 13 may contain an electric stove for cooking and also the articles required by law to be carried in lifeboats, such as sea anchor, oil, waste, iares, compass, etc.

On either side of the hull there are mountfloats 43, also preferably of balsa wood, mounted on a rope.

The modification disclosed in Figures 9 and 10 is intended as a lifeboat for use with vessels subjected to shell fire. In this modification balsa Wood 44 is substituted in place of the buoyancy tanks 16 shown in the first inodilication. Such a Wood is extremely light and buoyant and will, therefore, serve to keep the lifeboat afloat even though struck -by shell fire. There is also disclosed in this modication a pump 45 adapted to be driven from the motor 14 in any desired manner.

I claim:

A lifeboat comprising a hull having at the forward end'thereof a water-tight'compartment, a tank top deck, at the conter of the boat a compartment containing means for buoying up the boat in case of injury to the boat that would permit the water to enter the space below the tank top deck and at the stern three transversely spaced compartments the center ofwhich has a Water-tight closure and which contains a motor, a control cockpit, a steering wheel adjacent said control cockpit, a control lever for said motor adjacent said cockpit for controlling said sail and all operations of the boat.
