To allwhom 'it mafy conce-m.'

Be it known 'that I", Sinon C.. Joiixsox, :i citizen 'ofthe United States, residing at- De Kalbinthe county (if-Dekalb and State of Illinois, have invented a new and .useful Ioat, of which the following is a specification.

This'ini'ention relates to a boat of the nousinkable type, lwhich may he used for life g service or for pleasure use.A

The principal object of the invention is -the 'provision of a boat which is constructed with a novell arrangement'. of air compartments sothat the lioa't is rendered nactically unsinkllble, there being meansv suelh as shift- .ngballast balls serving to maintain the boat in i'ipright osition.

ith suci and other objects in view, the invention comprises the various novelfeatures of construction and arrangement of arts which will be more fully described hereinafter and set foyth with partieularity in .the claims appended hereto.

l VIn the-accom anying drawings, wliieh illnstrateoneeniliodiment of the invention. Figurev lisa side view of the boat.' Fig. i!

Fig. 3 is a phiii view partially in section. Figs. Land 5 are transverse sections taken, res ectivelyyonflines 4-4 and 5-5, Fig. il.

imitar reference characters are employed to designate corresponding parts throughout the views.,

Referrinl rto the drawings,' l designates the inner siell of the boat constituting the hold -or cockpit, and extending transrerlselitherein. are seats 2 which are preferahl wa- V ter-ti ht conipartn'ients and extend t'roin oneside to thc'other to hraee the shell. tending*.loiigitudinally. of the shell l is a falso-,bottom 3 which cooperates with the hottni'4 of the boat to form a longitudinal airftight compartment. extending ilafull length of the hold. fixtending entirely of the cock-pit or hold are provided with air-tight ,foinpartiuents S, and extendin .over thi-se end eoinpartiiieiits 8 and the. ein s of the` compartment i' are bow and stern compartments il and 10 which are formed by decking over the ends of the hoat from one side thereof t0 the other. .\s shown in Figs. laud 5, the tops of the compartments 9 and l() are rounded so that the water dashing over the saine will readil)l run oli froni the sides of the boat. lu order to prevent the water froni entering the cock-pit and filling the spaces between the seats and the end compartments. a plurality of scuppcr tubes ll are provided which are equipped with valves l2 for periuitting'the water to pass out of the boat. ln the intermediate seat compartments 2 are arranged shifting ballast halls l2', whit-h are normally maintained in tli` middle of ilie seat compartments by the latter being,r provided with false bottoms Il that slope inwardly toward tlie`ceiiter. 'l'hese halls serve to right the boat,`and in' ease the lat'ter is upset. they render the i righting of the boat less ditlicult. 'l`he boat ina r be propelled iii any suitable manner, as

isi-.a central longitudinal section thereof. 5

lor instance. hy oars, and for this purpose the oar-locks li are provided at tliesides of the boat adjacent the seats. Extending around the boat is a life line 1t. which is pas d through the fixed handles IT spaced around the. outside of the boat, whereby a reliable means is allorded for any persoii` overlaaird to iiiaiiitaiu a iriii hold ouA the hoat and thereby avoid drowning. ln i. 'oat constructed in this nuuiner. itI is -.\t'.-.'uiely tlillieult. if not iiiipossil'ile. to overturn the lmat'l'roiu the inside. and in ease of puin-tn ring ol' any eoinpartnieul, the boatI will still reinain alloat sinetthe water eannot, )ass around the shell l is an outer `hell t' which 5 provides a`n air-tight eoinp-.rtnieu'tl 't' extending from how to sti-rn alon; r both sides f of the boat. 'l`lie outer sla-ll t is approxi mately sein-eireular in eross st-etion. as

shown in Figs. 't and 5, and is hotelied to 4 I I l 1 desri'ilaaithe principle of operation of the the inner shell l approxiueuely alan-- the normal water hue.

he outer shell is pref i eriihly shaped to forni a pointed how and i 'from one i-oiupaitineuti to another.

tile the boat is especially useful with thtl lifesaving service. it may he used as a pleasure or other ei'at't..

l"ro|n .the foregoing description, taken in eouneetiou with tlnaeeonipairring drawings. the advantages of the eonstruetion and of the inethoil ol' operation will he readily apparent Io those skilled iu the art to whieh tlninvention apprrlains. and niiile. I have invention. together with thel derive which l now eonsider to he the hes-t enihiuliinentl thereof. l desire to luirerit understood thattlie device shown is iueiely illustrative, and

that suxh changes may ,be made when desired as are within the scope of the claims applended hereto. aving thus described the invention, what I claim as new, and desire lto secure by Letters Patent, isz- 1. A boat comprisinfjr an inner shell having a false bottom forming an air-tight chamber below the same, an outer shell extending entirely around the inner shell to cooperate therewith to form an air-tight compartment extending from the water line to the top of the inner shell, end air-tight compartments in the inner shell, and rbow and stern air-tight compartments formed at the ends of. the shell and separate from the other compartments.

2. A boat comprisin f an inner shell having a false bottom ibrming an air-tight chamber below the same, an outer shell cxtending entirely around the inner shell to cooperate therewith to form an air-tight. compartment extending from the Water line to the top of the inner shell, end air-tight compartments in the inner shell, seats forming air-tight compartments extending transversely of the inner shell, and bow and stern air-tight compartments formed at the ends 'of the shell. l

3. A boat comprising a shell having a lfalse bottom to provide an air-,tight compartment .extending from the bow to' the stern along the bottom of the boat, an ext-ernal shell securedto the tiret-mentioned shell to form an air-ti ht compartment extending along the sides o the boat and from bow to stern, box-like seats forming air-tight compartments arranged in the mner shell, each seat compartment having la false bottom sloping toward the center from opposite sides, and shiftable ballast balls mounted in the seat compartments.

'4. A boat comprising a shell having a false -bottom to providean air-tight compartaient extending from the bow to the stern along` the bottom of the boat, an external shell secured to the first-mentioned shell to form an air-tight compartment extending along the sides of the boat and from bow to stern, box-like seats forming airtight compartment-s arranged in the inner shell, each seat compartmentvhavin a false bottom slopin toward the centerrom opposite sides, s iiftable ballast balls mounted `1n the seat com artments, scupper tubes .passing through t e inner-.and outer shells,

and valves in the said' tubes.

1A boatl comprising innerl and outer shells, box-like seats forming air-tight compartmentsin the inner shell, each seat compartment having a false bottom slo ing toward thecenter from opposite si es, and shiftable bullas` balls mounted in the seat compartments.

In testimony that I claim the foregoing as m ture in the presence of two witnesses.
