b To all whom it concern:

the novel construction Be it known that I, LnoNAnno CRIMAUDO,

a subject of the King of Italy, residing at New York in the county of New York and State of New York, have invented new and useful Improvements. in Flying-Boats, of which the following is a specification.

This invention has to do with flying boats, and the principal objects thereof are: first, to produce a device of this character, provided with elements arranged in such manner as to adapt it for travel on the land, in the water and through the air; and, second, to provide such a device with a main steering mechanism common to the mecha-.

nisms by which the device is guided or steered on the land, in the water and through the air.

Another object is the provision of a device of this character having hinged wings or planes which are designed to be reciprocated or flapped in vertical arcs in unison for sustaining flight through the air, and which may be brought to rest when the boat is to travel on the land or in the sea.

With the foregoing and other objects,

which will become apparent as the description progresses, the invention consists in combination and arrangement of parts hereinafter described and shown in the accompan drawings, forming ,-'a material part of this specification, and in which Flgure 1 is a view in side elevation of the device, the operating mechanism being shown in dotted outline, and the rudder mechanism being partly broken away.

Fig. 2 is a longitudinal sectional view, taken on the line 2-2 of Fig. 1.

Fig. 3 is a similar view, taken on the line H of Fig. 1.

4 is a cross sectional view, taken on the line 44 of Fig. 1.

Fig. 5 is a similar view, taken on the line 5-5 of 1.

Fig. 6 is a rear elevational view.

Fig.1 is an elevational view of the main steermg mechanism, showing the same set in position for steering the device on land.

Fig. 8 is a similar view, but showing the mechanism set in-position for steering in the water and through the air.

Fig. 9 is a view 1n side elevation of the eccentric means for flapping the wings, and

Fig. 10 is a detail fragmental view of the steering column illustratingthe ball and socket joint connection.

In describing the invention in detail reference will first be had to Fig. 1, wherein the numeral represents the hull of the boat which is provided throughout its length with a longitudinal partition or floormg 16, upon which is located in the forward end a motor 17, and in the stern motor 18, and adjacent the center therebetween a series of batteries 29 representing a source of power for the motors and connected threwith with the usual electric wiring connectlons. 21 represents the seat-for the pilot who is protected from the elements by the wind shields 22. Secured exteriorly of the bow of the boat on the main drive shaft 23 is an air propeller 24, which serves to propel or drive the boat through the air and also on the land. Secured exteriorly of of the boat on the drive shaft 25, driven by the motor- 18 is a water propeller 26" to drive the boat through the water.

Exteriorly hinged to the stern of the boat 3y the hinges 27 and 27' is a vertical ruder.28, which is designed to guide or steer it when traveling in the water and throu h the air. To enable it to travel on land, t e boat is provided with a runnin gear which is secured to the underside 0 part adjacent the bow, and a part adjacent the stern.

The forward running gear consists of the supporting frame 29, in the rear element of which is journaled an inflated wheel 30, and

in the forward element of which is swiveled a shaft 32, having a lower bifurcated end in which is journaled a similar wheel 31.

The rear running gear consists of the frame 33 carrying an axle 34, to which are at tached the wheels 35, similar to those carried-b the forward running gear.

As est shown in Figs. 7 and 8, the upper end of the shaft 32 is journaled in bearing 36 and in angular bracket 37, both secured to the inner side of the hull. Fast on shaft 32 between the bearings 36'. and 37 is a rocker arm 38, the free end of which is provided with a toothed gearing-head 38'. Also secured to the innerbottom of the hull is a longitudinal bracket 39 having its opposed ends formed with upwardly projecting shoulders or bearings 40 and 40. Revoluble in the bearing 40' and held vertically the 111111, a

75 thestern' employ a in position by the bracket 41, on the vertical support 42, is a steerin column 43 carrying at its top end a ban wheel 44, ositioned immediately in front of the pi ots seat 21 for convenient manipulation by the pilot. In order to compensate for the angle it is required to make, the-steering column 43 is made in two parts operatively coupled by means ofthe ball and socket joint 44 provided just above the bracket 41. vertical portion of the steering column is provided with a longitudinal lug 45 adapt ed to fit in a groove provided in the hub of the gear 46, and which with the grooved head 38' when ati ts lowest elevation.

Revolubly mounted at its lower end in the bearing 40 and at its upper end in the bearing 47 provided in the end of the angular bracket 48 is a vertical shaft 49 on which is rigidly secured the bevel gear 50. Also fast on 49, immediately below said bevel gear is a rocker arm 51 which is formed with a toothed head 51, similar to the head formed with the arm 38, designed to mesh with the gear 46 when in elevated position.

To provide for the shifting of gear 46, I lever 52 which is pivoted at one end as at 53 to abracket 54, and at the other end to a sleeve formed on the underside of said gear 46. Positioned within convenient reach of the pilot, and provided with a shank of bell-crank formation, pivoted at 55, is an operating lever 56. The lower end of this lever is pivotally connected with the forward portion of 52 by a link 57.

J ournaled in the bearing 58 provided inthe bracket 48 is a longitudinal shaft 59 which carries a bevel gear 60 in mesh with the bevel gear 50. As shown in Fig. 1, this shaft 59 extends to the stern of the boat and is supported in the bearings provided in brackets 61 and 62, the latter bracket being angular in form and having at its free end a bearing 63 wherein is journaled the lower end of the vertical shaft 64, the upper end of which is journaled in the bracket 65, and provided with a gear 66 (Fig. 2). A pair of bevel gears 67 and 68 provide for the transmission.

of motion from shaft 59 to shaft 64. As

best shown in Fig. 2, a transmission arm 69 having a gearing-head in mesh with the gear 66 serves to transmit motion to the rudder28. From the foregoing it will be obvious that vvhen the gear 46 is in mesh with the rocker arm 38, each movement of the steering column 43 will produce a similar turn of wheel 31. Also it will be obvious that when the adjustable gear 46 is raised so as to mesh with the head of the transmission arm 51, each movement of the steering. column will be transmitted to the rudderg28.

In Fig. 1, it will be seen that the longitudinal shaft 70, journaled inthe bearings as 71 on the under-side ofthe flooring 16, is

The

is adapted to mesh aaeaeee driven by the main shaft 23 through the engaged gears 72 and 73. Asshown in Fig. 5, the shaft 7 0 carries a gear to drive the large gear 74 which has formed on its face an eccentric groove 75. A horizontal arm 76 is centrally secured to a pin 77 the opposite end of which is provided with a roller 78 (Fig. 9) operative in the eccentric groove 75. Hinged in the oppositely disposed brackets 79 and 79 on the exterior of the hull arewings or planes 80 and 80', whicn are provided with arms 81 and 81' angularly pro ecting therefrom and extending into the hull. Pivotally connecting the free ends of arms 81 and 81 with the free ends of the horizontal lever 76 are links 82 and 82'. By means of this arrangement, the lever 76 is given a vertical motion in the same plane when the shaft 70 is rotatated, by -which motion the wings 80 and 80' are reciprocated or flapped in vertical arcs once with each rotation of the shaft. In order to make the flapping movements of thewings positively uniform, a spring 83 is'employed to connect the pivoted ends of the arms 81 and 81.

A second pair of wings 84 and 84 are similarly secured near the bow of the boat. These are operated by identical mechanism driven b the shaft 70. .In this manner I provide or the flapping in unison of the two pairs of wings.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is -1. In a device of the character described, the combination with a hull carrying a running gear including a swiveled wheel, an air propeller carried on the bow of the boat and means for driving it, a water propeller carried on the stern of the boat and independent means for driving it,- a rudder car- 2.
