(UNITED STATES PATENT FFICE;

BOAT.

Application filed march 19, aaasenarno. 86, 034. Renewed June This invention relates to boats, the general object being theprovi'sion of a board having buoyant members provided uponits opposite ends and fitted with both propulsionand steering apparatus and which may prove of great value as a lifeboat or afford a mechanical addition to the usual and con} v-entional form 'or forms of surfboards.

lVith the above and other objects in view,

) the invention further includes the following novel features and details of construction,

to be hereinafter more fully described, illustrated in the accompanying drawings, and

pointed out in the appended claims.

In the drawings i V Figure 1 is a side elevation ofthe invention.

Figure 2 is a fragmentary longitudinal section taken through the board proper and illustrating the construction and arrangement of the propulsion apparatus.

Figure 3 is a top' plan view of the invention.'

Figure 4t is a vertical 1 ftf of Figure 1.

Figure 5 is a sectional View taken through a buoyant member and the supporting means therefor. Referring to 'thef -drawings in' detail,

section taken on line wherein like characters of reference denote corresponding parts, thereference character indicates aboard having enlarged end portions 11 and including.semi-circular longitudinally split gconcave plates 12 having theirmeeting lower edges arranged in overlapping relation and secured to the upper side of the enlarged end portions adjacent the edges thereof. vide openings 13 therein through which air l valves 14 may protrude from buoyant air filled tubes 15 housed within the compartments defined by the plates 12. Such tubes 15 serve to float a person or persons upon the hoard when submerged an appropriate depth withinthe water. The above entitled invention is primarily adapted for occupancy and operation of two persons, one upon eachend for operating a propulsion steering apparatus, which will be presently apparent. p

The propulsion apparatus consists of an operating lever 16 pivotally mounted off center upon the board and extends and adapted for oscillatory movement within an 5 elongated slot 17 provided in the board. A

relativ ly narrow board 18 suspended at its Their upper sides proouter endnpon the under side of theboard 10 and adjacent one end thereof through the instrumentality of a pivoted bar 19 is adapted for simultaneousoperationwith the lever 16 which in turnhas its lower endipivoted within abifurcated portion 20 defined ithin the forward end of the board 18. A multiplicity of plates or paddles 21 are i' ot- 'ally mounted'upon'the under side of the board 18 and restricted as to pivotal movement in one direction oppositely disposed plates 22 suspended from the under side of the board 18. Such plates or paddles 21 are adapted for operation and for relative pivotal swinging movement in the positions as clearly illustrated in Figures 1 and2 of the drawings. Said plates 12 also serve as an enclosure or seat for the operators of the boat. k ,7

' The steering apparatus consists of asteei ing post 23 set at an inclination and in an opposite direction with respect to the oper- "ating lever 16, in order that the latter may be easily manipulated upon the board 10. A spool-124; is mounted thereon and adapted for simultaneous rotation therewith. A rudder such as indicated ,at 25 provides a cutout portion '26 within its upper side for the reception of an appropriate portion of the enlarged end portion 11 of the board '10 and pivotally mounted upon the upper side thereof while a reduced elongated extension 27 extends beneath and longitudinally of'tlre boardan'd has the opposite ends ofa cable 28-secured to its opposite sides. Said cable has its intermediate portionwrapped upon the spool 24- and its remaining length trained over grooved pulleys 29 positioned upon the under side of the particular enlarged end portion 11.

In the use and operation of the propulsion apparatus it is clearly apparent and 'inanifest that the operator may be seated upon an enlarged end portion .11 of the board 10 and held againstaccidental displacement thereon through the instrrnnern tality of the-plates 12 housing the tube 15 while he may support andbrace' himself upon foot rests 3O suspended from the under side ,of the board lOp as may the person seated upon the opposed enlarged end 11 of the board 10. The oscillatory movement imparted to, the board 18 by the operation of, the lever 16 will allow the plates or pad dles to rise and fall upon their pivots to thrust the Water in opposite dire tion with respect to the direction of travel pursued by the occupants ot the boat.

It will thus be noted that the invention as previously described and illustrated affords an exceedingly useful and advantageous form of boat capable of being stored within a confined area upon vessels or transports to serve as a medium of life saving apparatus,

seating two persons and offering propulsion" and steering means therefor in order that the boatmay leave the immediate vicinity of a sinking vessel, which creates a suction upon snbmerging and tends to draw the lite boats and survivors downwardly therew1th.- The invention in addition provides a boat which may he used/at water fronts and bathing beaches and which owing to the construction thereof maybemanufactured in great numis claimed is z 1. A 'boat comprising a board, buoyant members arranged upon its upper side and adjacent its opposite ends to prevent displacement of persons seated thereon, a rudder mounted tor pivotal and lateral swing ing movementupon the under side of the board, a steering post journaled upon the upper side or the board and connected with the rudder, and a propulsion apparatus .mounted upon the under side of the board and having an operating lever connected therewith. 2. A boat comprising a board. having semi-circular buoyant members secured to its upper side and adjacent its opposite ends to provide seats and prevent accidental displacement of persons seated upon the board comprising a longitudinally movable plate suspended upon the underside of the board adjacent its opposite end, and a lever operable upon the upper side of the board and having its lower end connected with the atoreniei'itioned plate to impart the necessary momentum thereto.

3. A'boat comprising a board having semicircular buoyant members secured to its upper side and adjacent its opposite ends, a rudder mounted for pivotal lateral swinging movement upon the under side of the board and adjacent one end thereof, a steering post journaled upon the upper side of the board and having a spool fixed thereto upon which is wrapped the intermediate portions of a cable having its remaining length trained over pulleys mounted upon the under side of the board and having its ends con nected with the opposite sides ot the rudder, an operating mechanism comprising a relatively narrow plate suspended from the under side of the aforementioned board and having a plurality of spaced parallel pivotal y mounted plates upon its under side and an operating lever mounted for oscillatory movementwithin a slotted portion in the board and having its lower end connected with one end of. the relatively narrow plate for imparting the necessary momentum thereto and to the plates suspended there from. v p

In testimony whereof I atlix my signature.
