LIFE-BOAT.

SPECIFICATION forming part of Letters Patent N o. 642,622, dated February 6, 1900.

Application filed December 5, 1898. Serial No. 698,350. (No model.)

To all whom, it may concern:

Be it known that we, WILLEM PETRUS MULI, a subject of Her Majesty the Queen of Holland, residing at Leyden, in the Kingdom of the Netherlands, and BENJAMIN HY- MANs vAN DEN BERG, a subject of His Majesty the King of Belgium, residing at Antwerp, in the Kingdom of Belgium, have invented a new and useful Life-Boat, (for which we have obtained provisional protection in Great Britain, No. 23,314, bearing date November 5, 1898, while a patent has also been applied for in Germany, dated November 8, 1898, and in France, Serial No. 270,634, dated November 8, 1898,) of which the following is a specification.

The present invention relates to an improved life-boat for sea-going vessels and the like, which boat is absolutely secured against upsetting, but which when in the folded condition does not take up more room than an ordinary ships boat.

Ships boats of the usual kind, in which the passengers in case of shipwreck endeavor to save their lives, lose much of their value because in the case of storms and rough sea the danger of upsetting is very great, and this also often occurs when in the panic the passengers press to one side of the boat. Consequently these boats deserve the name of lifeboats only partially,because their safety is not by any means assured.

The object of the present invention consists of a boat especially for sea-going ships, which in reality deserves the name of a lifeboat, because it not only possesses all the advantages which the present boats possess, but, in addition to this, it possesses an arrangement whereby the upsetting or sinking is practically made impossible, even under the most unfavorable circumstances. This arrangement, which forms the subject of the present application for a patent, is carried in the inside of the boat while the same is out of use, and thereby the dimensions of a boat of this kind are rendered no greater than those of an ordinary ships boat. In case of into compartments by water-tight divisions. These cylinders possess a great buoyancy and are fixed to long supports, which eect the connection with the boat. These floating outriggers, connected by a long leverage, form a support which resists the capsizin g of the boat.

The invention is illustrated in the accompanying drawings in connection with a boat which itself is devised to comply with the requirements Which may be made in the case of a life-boat.

In the drawings, Figure l represents a longitudinal section; Fig. 2, a transverse section; Fig. 3, a plan view, and Figs. 4 to 6 various details on a larger scale. Fig. 7 shows, on an enlarged scale, the locking mechanism securing the supports of the iioat to the side of the boat.

The boat R is provided in the well-known manner with a double bottom, and the intermediate space is filled with water-tight cylinders M. Over this double bottom,at each side,

are placed the lockers K, which act at the V same time as seat-s and as water-tight compartments for containing tools and food. The cisterns H are .Iilled with oil, whichcan be discharged through the tubes I and serve in case of need to render the water smooth in the neighborhood of the boat. In the bottom of the boat are placed the tubes G, Figs. 2, 3,

and 6, through which any water coming onboard can flow out and which are provided with back-pressure valves to prevent any water flowing in from the outside. Three strong bars D are secured at each side of the boat,- which terminate at the gunwale in hinges. Upon these hinges the supports B revolve, which supports B connect the hollow cylinders A with the boat by aid of the connectingbars S, which serve to hold the cylinders A in their placeand to strengthen the aforesaid bars B. The cylindrical hollow bodies A are divided by means of water-tight partitions into compartments, and they terminate in front and behind in pointed ends. The supports VB are connected by means of the tierods F.

N indicates a handle for the purpose o f bringing the cylinders inboard. In Figs. 2 and 3 the position of the cylinders A when the boat is out of use is indicated by dotted Ioo of the boat as a life-boat, the cylinders Aare lturned overboard into the position shown in full lines in Fig. 3 and the supports B locked at E. The boat can then be lowered into the water. The hollow water-tight cylinders A possess a very great buoyancy, which, being placed on the long leverage of the supports Il, gives a stability which renders the capsizing of the boat almost impossible.

boat sinking is also almost excluded. The division of the cylinders into water-tight com partments causes in the case of an injury that the same is limited to the compartment actually damaged and prevents the water passing into the remainder of the cylinder. The tapering form in front and behind aids the progress of the boat in thewater through the diminished resistance. The bars F and C serve also as hand-rails-the bars F for the support of persons who may have fallen into downward and passes through a horizontal slot at the lower end of the supports. Said bolt is revolved a quarter-turn, which releases the support. The bolt E is secured inside the boat by means of the Cotter-pin e.

Owingto its very great buoyancy the danger of the The bolt can, however, be secured by means of a wedge or the like in order to connect the support at E rmly with the rails D or the sides of the boat, or the bolting device mayact automatically by means of a spring-catch or the like locking the end of the bolt when inserted in the aperture of the bar D. At the front of the boat there is a device arranged for the rower, for which purpose the rowlocks q are attached.

Q, Fig. 5, is au adjustable row-lock which can be placed at any convenient point, so that the boat may be steered also from the interior thereof, and the oars can reach over the cylinders A in case of need.

What we claim isl. In a life-boat, hollow buoyant cylinders parallel to the sides `of the boat, horizontal rails on the gunwales of said boat, supporting-arms pivoted on said rails and rigidly attached to said cylinders, `locking devices for said arms on the outside of the boat, and a lever-handle operated from the interior of the boat for raising the said cylinders and brin ging them into the interior ot' the boat.

2. In a life-boat, in combination adjustable iloats A, supporting-bars D secured to the boat, horizontal rails C supported by said bars, duplex connecting-bars B attached to the floats, and pivoted at their upper inward ends to the rail C, transverse supports S between the bars B, a handle N, and outer locking devices E engaging with the lower inward ends of the bars B.

In witness whereof we have hereunto set our hands in presence of two witnesses.
