To all whom 'it mag/concern: Y

`Be it vknown that I, Jol-IN H. STonLT, a citie zen of the United-States,` residing at Sebewaing, in the 4county of Huron and State-of Michigan, Yhave invented newfand useful Improvements in Life-Boats, of whichthefollowing is afspecification This'in'vention relates-to life boats, and has for its objectto produce'a safe, reliable and non-collapsibleA boatfof the classv described adapted to be driven by al motor and either to be carried as al fart ofthe -equip' ment of a sea-going vesse for` to be usedfby` 'life saving corps, the boat being especially adapted for the latter purpose. y y

With the above and other objects in view, thenature of which wil-l more fully appear as the description proceeds, the inventionconsists the novelconstruction, combination and arrangement' of parts rasfherein fully described, illustrated and claimed.

yIn the accompanying drawings z-Figu-re 1 is a plan view of the lifeboat embodying the present invention, showing one ofthe side extension boats set in position for useand the other side extension-boatffolded. Fig. 2 is a plan view of the boat on al1-enlarged scale omitting the `deck in order to `illustrate `the'interior construction Fig. Sis aside elevation of theboat. fFig. 4 is a vertical fore and aft section through the rear end of the boat, showing a portion ofthe steering mechanism. Figp is amid-ship section.

Fig. v6 is a detaillongitudinal section through 'a portion of one of the buoyant side-fenders. Fig. 7 is a verticalcross section Vthrough one of the foldingfside lextension-boats showing the meansfor holding' the same extended.

Fig. 8 is an enlarged detail longitudinal section through one of the bumper rods. Y

In the Y preferred embodiment of the invention the hull 1 of the boat is long, narrow and deep or what is usually termed theJ cutter type in order to lgive the requisite, stability and speed to the boat. The boat is equipped with twin screw p-ropellers arranged one at.

each sideas shown in Fig. 5, each of said pro"-k pellersbeingin theff-or'm-of as'pirals'crew as shown at 2.v `The propellers 2 are hungin suitable bearings Vat their `forward and rear endsand may be geared in any suitable -manner to a motor of any desired type such'gearing and motor not being illustrated asthey forni no part of the `present invention.

^ The form ofpropeller' shown and described however, willbe found especiallyeective- The 'hull is alsoequ'ipped with the usual rude der `3 located at the stern Vand provided with `a rudder post' 4 which .extends throughthe counter of the `hull ,andV isrprovided `at its upperlend with a beveled gear wheel 5vwhich meshes with and 4is 4actuated-by another beveled'gear vwheel -on the rear'end of a steer ing shaft J7 mounted in suitable bearings and provided with a-steeri-ng wheel fast thereon.

lin carrying out the presentinvention, the yhull Vof the boat is completely decked over as best illustrated-in Figs. 1 and 5, the deck being -peeked centrally as shown and slanting 'infopposite directions from the center toward the sidesofgthe boat,-the major portions of the sides being described en straight parallel lines as shown .in'Fig Lto provide for the attachment theretoiof the folding side eXten sion boats hereinafter more `particularly described.' The hull is also divided into a plurality of independent water tight compartments by means` of bulkheadls 9, 10 and 11 While the deck-.above the several compartments thus formed is provided` with a corresponding numberof hatches 12v giving-access tothe compartments andrenderingrthe same independentof each other so that in .case one of said compartments shouldfbecome flooded the others' will: be protected, Extending upward frornthedeclr at suitable-intervals vare rail 13 V.which preference extends entirely around the boat as shown in Fig. :1.

1.4 designates al turret `Vwhich as will be seen l by referenceto fFig. 5 iswfrusto-conical in` shape for provided `with a slanting outer sur- `stanchions 13 which support a hand or'guard face tobetter'deflect the sea,the said turret i. i

beingl provided with any .desired number .of

Vdead lines 15 to enable the helfmsmanto make observationsinheither direction to assisthiminmanagin thelboat. Thetop or nmay-be Aopenfto give accessto the rear compartment over whichthe-turret is located.

roof ofthe turret .em' odies` a hatch 15 which n Extendingoutwardly in substantially hori- .Zontal planesfrolnthe sides `andbow and stern ofthe boat are bumper -rods:17A which are connected at@ their outer en-ds by bumper rails 18 forminga guar-dto. prevent damage tolthefboat'by'rcontact.with other vessels or mooring places. Each of said rods: is ofthe .construction illustrated f in* detail in Fig.8 :wherein itwill'beseen thatlthe outer section of the rod passes Athrough an Aopening A119,-in the side-.ofthe hull `and isi-provided with a head 20 which operates against a spring 21 'arranged in a tubular ,section 22 of the bumper rod. The section 22 is provided at its inner end with a head 23 which slides in a tubular sectionv 24 containing another spring` 25. InV like manner the section 24 is provided at its inner end with a head 26 which bears against another spring 27 housed on the innermost section 28 of the bumper rod. As many tubular telescopic sections vmay be employed as may be found necessary side extension boat embodies the oppositely arranged side sections 30 and a pair of bottom sections 31 which are hinged at their outer edges to the sides 30 and hinged in other inner edges to a keel 32. At the bow and stern, each folding side extension boat is provided with triangular bottom sections 33 Vwhich are hinged to a keel section 34, the latter being hinged to the main gear section as shown at 35 while the triangular bottom secj tions 33 are hinged to the main bottom sections 31 as shown at 36. The bow and stern of each folding side extension boat also comprises the triangular side sections 37 which are hinged to the triangular bottom sections 33 and also hinged to the side sections 30 as shown at 38. By means of the construction just described, each of the folding side extension boats is adapted to be folded from the position shown at one side of Figs. 1 and 5 to the position shown at the opposite side and when in the latter position said extension boats occupy but small space while they are extended and they not only accommodate a large number of persons but they also V add materially to the ease, readiness and stability of the boat, as a whole.

The folding side extension boats are held extended by means of seats 39 any number of which may be employed, the opposite ends of each seat being received between parallel cleats 40 on the sides of the boats while a tie rod 41 extends from an eye 42 on the seat to an eye 43 on the keel as shown in Fig. 7, thus firmly anchoring the seat in place and preventing any liability of the extension boat from accidentally collapsing.

Each folding side extension boat has connected therewith a plurality of stays 44 shown in Figs. 3 and 5 each of said stays being hinged to the side of the hull as shown at 4,5 while the outer end thereof is provided `with a tee-shaped head 46, the stay being adapted to slide through an eye or loop 47 adjacent to the outer lower angle or corner ofthe extension boat. At one or more intermediate points, each stay 44 is jointed or provided with sections hinged together as shown at 48 to enable said stay to fold alongside of the folded extension boat as shown at the left hand of Fig. 5. The stays 44 effectk ively guard against the extension boats being turned away from the sides of the main hull and this is further aided by the bou7 and stern connections 49 and 50 respectively, said connections being preferably in the form of chains, each of which has one end con nected to the corresponding end of the extension boat while the other end is connected to the main hull as clearly shown in Figs. 1 and 3. The boat is further provided on opposite sides with buoyant fenders 51 extending practically the entire length thereof each of said fenders being in the form of a hollow tube as shown in Fig. 6 containing a plurality of air-tight sections 52 each containing air and each being independent of the other so that in case one of said sections should become flooded the remaining sections will not be affected. The fenders not only add to the buoyancy of the boat as a whole but also act in the capacity of fenders to prevent injury to the hull when the hull comes in contact with other hulls or obstacles. The boat is also equipped with bow fenders 53 illustrated in Figs. 1 and 3, the same being hinged to the stem of the boat at 54 and having rearwardly diverging sides conforming to the shear of the bow of the boat as shown in Fig. 1, the fender being held forward by means of one or more cushioning springs 55 interposed between the stem of the boat and the stem of the fender. The bow fender 53 protects the stem of the hull and also will be found effective in rescuing persons from a wreck or grounded vessel.

ln addition to the usual rudder 3, l provide two series of emergency rudders each series comprising a forward rudder 56 and a rear rudder 57. These rudders are preferably led into recesses in the keel as best indicated in Fig. 3 and have posts 58 and 59 provided at their upper ends with tillers 60 and 61. The forward tillers 6() comprise two arms each while the rear tillers comprise but a single arm. To operate the emergency rudders l provide two sets of treadles, each set comprising a right hand treadle 62 and a left hand treadle 63. Fromthe right hand treadle 62 a steering rope or cable 63 passes upward over a guide pulley 64 to the rear end of the tiller arm 61 and from thence around other pulleys 65 and 66 to the left hand treadle 63. From the right hand treadle 62 a steering rope or cable 67 extends around suitable guide pulleys to the forward arm of one of the forward tillers 60 while from the opposite arm of said tiller another back to the left hand treadle 63. The hel msman sitting upon a seat 69 just over the treadles may readily depress one or the other of either pair of treadles and thus' swing the emergency rudders 56 and 57 outward and inward, correspondingly deflecting the course of the boat. The emergency rudders are particularly Auseful incase of injury of the ordinary or main rudder 3 and may also be used as an auxiliary to the rudder 3 when it is necessary'to make unusually quick or abrupt turns in the boat.-
