LIFE-BOAT.

Spepication of Letters Patent.

Patented Nov, l?, 908.

Application led August 23, 1.067. Serial No. 389,880.

To all whom it may concern.'

Be it known that I, Jol-IN H. S'xonL'r, e subject of the Emperor of Gern'reny, residet Seben/sing, in the county of Huron and State of Michigan, have invented new und useful Improvements in Lifeoets, of which the followin is e, specification.

This invention rates to an improved life boat adapted to be carried by passenger end other vessels for emergency use in the event of ship wreck; and the invention has for its object to rovide a boat of this character which sh l be simple in construction and efficient in operation; which may be readily and safely launched; which shell be self r' htin which, if it should be cerried vwith e oun ering vessel below the surface of the Water, will speedily rise to the surface; which shall be covered over so that the occupants will be protected from the elements; which shall be rovided with means for propulsion .operable from the inside; und which shall possess superior advantages in point of simplicity, durability and general efficiency.

'With these end other ends in view which V will readily lappear as the nature of the invention is better understood, .the same consists inthe improved construction and novel arrangement and combination of parts which will hereinafter be fully described and perticularly pointed out in the claims.

In the aeeompanyin drawing has been illustrated a sim le en preferred form f the invention, it eing, however, understood that no limitation is necessarily made to the precise structural details therein. exhibited but that changes, alterations and modifications within the scope. of the claims may be resorted to when desired. I

In the drawin s:--Figure 1 is n side elevetion of a life oet constructed in accordenceV with the invention. Fig. 2 is e longitudinal vertical sectional View of the same. Fig. 3 is u' vertical transverse sectional view teken on the f lane indicated by the line 3*-3 in Fig. 2. Fig. 4 is e detail view of the spur Wheel 7. Fig. 5 is eideteil plan view.

Correspondin parts in the several figures are denoted by like characters of reference.

The improved life boat in its preferred form consists .of en fipproxinmM drlcel body A which is secured suitably connected with un el'. Y member B preferably` consisting ot a me tallic casting which is sul'licienily Emery to cause the boat to be self righting; mid keel member beit formed with e. down- Wurdly extendinglongitudinal rib 3 which constitutes the keel, and with an elongated tubular passage 2 wherein the propulsion member is mounted, es will be presently fully described. The tubular passage Q has been iilustreted es bcing provided with a lining 3, which muy be interiorly polished so as to resent u smooth and iioirobstructive enti-friction surface. The tubular tissage is provided with crosspieces ai Ording bearings Ator a slinttveerrying e plurality of propellers 6 Aund carrying .else

a spur wheel t which is @contested by e. trein of gearing' 5?. with a shaft J snpui-refi for rotation inside fait tlze body ot' the boei" und having e bend Wheel i0 Wire.. f it may be operated for the purpose of t... emitting motion to the propeller sbr-ttt.. imssage and the lining oii the ettm vided with enlarged portiere.; il rij the cross bars 4 and to the gearing.; purpose of permitting Water to pms reely throufrh the seid passage without lfnn; fueterialy obstructed by seid cross buis and gearing. The spur Wheel 7, skeleton construction, being provided with s okee 1Q. which latter are preferably set s antingly, as will be seen in Fig. 4f of the drawings,

thus transformingr thc spur Wheel into a propeller which will assist in the propulsion of the boat.

The body A. of the bont muy be constructed in any suitable and convenient menner of matched or iep ed lumber, end the forward portion of the ody is protected and reinforced by e. sheathing 13 of sheet metal.

'I he rib 1 constitutes the keel which projects rearwardly of the body of the keel member B, as will be clearly seen in Figs, l and El, und it affords u bearing for thc lower cxil'eniitv of the post lll curivins the rudder 1:3 which letter is :lt-oommodatml in the space between the keel l and 'thc stern post l through which the rudder post extends, said The tubular moreover, ofY

rudder post being provided at its upper end with a cross bar or lever 17 to the ends of which the steering lines 18 are attached; said lines being guided throuvh casing tubes 19 to a conveniently accessible point within the body oitl the boat.

The body of the boat is provided at intervals with transverse partitions 20 which not only serve to brace and reinforce the structure, but which also divide the body of the boat into a plurality of Water tight coinpartmcnts 21; the partitions 20 being provided with apertures 22 sufciently large to permit passengers to pass therethrough, and provided i th suitable closures 23.` The compartments of the boat are accessible through hatch ways 24 in the deck or upper portion of the boat; said hatch ways being provided with tightly fitting hatches 25 Which are preferably constructed in such a manner as to be perfectly Water tight. The compartments of the boat are rovided with seats 26 which are referalily arranged lengthwise, along the sides of the compartments, so as to enable the occupants to pass from one end of the boat to the other conveniently and without discominoding each other. At the stem and at'the stern of the boat are formed air chambers 27, and air tanks 28 are suitably arranged lengthwise in some of the compartmentsl for the purpose of assisting the boat in rising to the surface of the Water in ca'se it should become sublockers 29 are also provided at various laces for water and provisions. Deadights 30 are inserted at various places in the sides of the boat forthe purpose of at'- fording light to the occupants.

The operation and advantages of this invention will be readily understood from the foregoing description taken in connection with the drawings hereto annexed by those skilled in the art to which it appertains.

The improved life boat may be carried upon the deck of a vessel, or it may be slunor from suitable davits, or it may be supporte upon a suitably constructed slide which will enable it to be readily launched in case of einer ency. It is intended that the boat shall e constantly supplied with water and provisions, and that the air chambers and tanks shall be kept tightly closed. In case of emergency, the passengers and crew may enter the compartments of the boat through the hatch ways of the latter, the crew being instructed by previous drills how to take their stations and how to manipulate the boat. If time permits the boat Will be promptly launched, but if in the event of sudden disaster the boat should go down with the vessel, it is intended that it shall be .secured in such a manner that it will become detached by its own buoyancy, induced by the air tanks and compartments, so that it will readil rise to the surface. The boat may be readi y steered, and propelled either in a forward or rearward direction by proper1 rotating the lpro elling shaft; the propu sion of the boat lieing effected Without necessity of opening the hatches or exposing the occupants to the elements. The hatches, however, may be slightly raised, at intervals, for the purpose of supplying fresh air.

The improved life boat will be manageable and etlicient under circumstances Where boats propelled by oars and provided with sails will be useless and unserviceable. The construction is simple; it Will be found thoroughly efficient for the purposes for which it is rovided.

aving thus described the invention, what l. In a life boat a cylindrical body, an elongated keel member having a longitudiial tubular passage provided at intervals with expanded portions, a propulsion member fitted in the passage and including a spur Wheel arranged in one of the expanded portions of the passage, and cross bars constitutinfv bearings for the propeller shaft disposed adjacent to the expanded portions.
