This invention relates to new and useful provementsin boats, and has particular reference lto a safety water cradle boat.

rate air compartments.

"insofar as the float is concerned, it is proposed that a plurality of arms be mounted on the sides of thehull and support said floats extended along the sides of the hull.

It is further proposed that each oat include a metal casing, a plurality of discs dividing it into separate compartments and air bladders mounted within said compartments and adapted to be inflated with air. Y

The invention also contemplates a mechanism for propelling and steering the boat.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appendled claims in which the various novel features o'f the invention are more particularly set forth.

'I'he safety water cradle boat, in accordance with this invention,V includes `a `hull l5 compris'- ing a plurality of transverse framel sections lli and a completely enclosed sheet metal casingl I1 mounted on said transverse frame sections and forming a plurality of separate air compartments I8, i9, etc. Each of said transversev frame 'sec tions I6 has a central core layerZ of wood, and sheet metal face layers 2l mounted Ontheside faces ofthe core layersl 20. The core layers are formedwith a plurality of perforationsl 22 or other passages. However, these perforations or passages are closed by the face-layers 2|. Fastening elements, such as rivets 23 connect the layers' 2li and 2l together as a unit. Y Each of the air compartments I8, I8,.etc., is provided with an air valve 24 by which'l compressed air may be forced into said compartment. The compartments are hermetically sealed f so that if one or more becomes punctured, the remaining lcompartments will still function to hold the boat afloat. The traverse frame sections IE are provided with plates 25 mounted at the top corners thereof and provided with projecting studs 26 which engage through the metal casing il. Suitable nuts-or other fastening elements 21, are engaged on the outer ends of thesestuds 26 tol assist in joining the transverse frame sec'- ti'ons 'f5 v"and casing v'I'l togetherv (see particularly Fig-."6 in thisrespect); w z 1,51 i, -'Inehull' li'sprovide'd withan ,open top cabin 28' provided witli'a vfloor-2 il anda seat back 3llff the-,co-nvenince c" f fa'fr 1 foperatoif- 'of the boat'.

The construction .is such that the crank 32 may be manuallyv turned for driving the propeller 36 to p'ropel't'hel boat.

Means is also provided for steering the boat, and this means includes a steering bar 38 pivotally mounted at its center by a pintle 39 mounted on the cabinet oor 29. The steering bar 38 is provided with a, pair of foot rests 40 on opposite sides of the pintle 39 by which the bar 38 may be pivoted in one direction or the other. Cables 4l connect with the ends of the bar 38 and are guided over pulleys 42 and through passages 43 in the side Walls of the cabin 28 (see Fig. 6). These cables 4I extend to the rear of the boat and extend over additional guiding pulleys 44 and then connect with opposite sides of a rudder 45 which is pivotally mounted in a frame 46 mounted on the boat.

A plurality of arms 50 is mounted on the sides of the hull I and support floats 5I. There are two of these oats 5I, each extending along one of the sides of the hull. Each float 5I includes a hollow metal casing 52 divided by a plurality of discs or partitions 53 into a-plurality of separate chambers. AEach of the chambers is provided with a bladder 54 which has the usual air control valve 55 by which the bladder maybe supplied with compressed air. The rear ends 5I of the oats `are bent upwards, as clearly shown in Figs. 1 and 5.. The iront ends 5I of the floats are also benil upwards. These front ends are provided with wedge shaped members 55 which will assist in cutting the water when the boat moves forwards. Each .of `these wedge shaped members 56 is formed from a hollow body which is open at its rear end 51. The upturned ends 5I extend into the open rear ends 5l' and then up through top openings in the top walls of the members 56. The discs 53 may also be connected kbysuitable connecting rods 53' to reinforce the floats 5I.

Each arm 55 is made from a stationary section 58 and an'adjustable'section 59. Each'stationary section-58 is fixedly mounted on the hull I5 of the boat and lextends outwards. Each section 59 is fixedly mounted on a float 5I and extends inwards. The inner ends of the sections 59- are pivotally connected by hinge constructions 60 with slides 6I sldably mounted on the sections 58. A set screw 62 threadedly engages through eachstationary section and is adapted to abut a movable section for holding these parts in relative pivoted positions. Set screws 63 engage through the slides 4(il and abut the edges of `theV stationary sections 58 to hold the slides 6 I .in relatively fixed positions.

The set 'screws 63 may be loosened and then the :floats 5| may be movedyinwards or outwards, so ,as toplace Vthem at selectedpositions relative tothe hull Ii5. Then the'rset'screws 63 are tightened. ,In the event .that a relatively light person is using the boat, it-will be found that the hull I5 floats ata higher elevation. In this event the floats 5l will hang downwards andrest on the water. Ihesetscrews maythen be extended downwardssoasto hold the hinge sections 59 in their .downwardly extended positions. Thus the set screws 62 prevent loose flapping of the floats 5! and serve todirectly communicate the buoyancy ofthe floats 5'I to the hull I5.

The operation of the device is as follows:

A passenger may sit on the floor 28 of the cabin 28 and operate the propelling and steering mechanisms of the boat. 'I'he oat-s 5I extend laterally of the hull of the boat and stabilize the boat to preventA it from easily tipping over. The floats 5I are of such design that they facilitate cutting the Water and so reducing the head on resistance of the boat.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
