ATTORNEY Patented Oct. 29, 1940 UNITED STATES 7 VEHICLE Edmond Th. Dgallier, Lausanne, Switzerland Application July 6, 1938,Serial No. 217,681 In Switzerland July 6, 1937 9 Claims. (Cl. 114-67) This invention relates to vehicles, and more particularly to marine vessels having rotatable float members which are adapted for propelling and supporting the vessel abovewater.

The form of the invention illustrated in the accompanying drawings, by way of example, is a marine vessel which rests in the water upon a plurality of rotatable float members analogous to those employed in the pending U. S. application SerialNo. 183,278. The float members are mounted upon suitable float bearing frames which are adapted for telescopically engaging 0 downwardly extending side frames of a chassis or frame Work. The plurality of floats are enabled to follow the irregular changing surface, for example, of a heavy sea, without causing appreciable rolling or pitching of the chassis. A cylinder and piston arrangement is provided for governing the telescopic engagement of' said float bearing frames with said side frames. The cylinders are interconnected by a'suitable conduit system and a gaseous medium is introduced 20 therein which assists-in controlling the motion of the floats and supports the chassis. The floats are operatively connected to power means. for propelling the vessel. The float bearing frames which oscillate substantially in a vertical direction may be operatively connected to means for converting this movement into power." The latter means: are preferably tobe operated when the vessel is at anchor whereby the energy of sea swells may be utilized. I

In the form shown in' Figs l to 3 the, vehicle comprisesa rigid chassis or framework 2' having downwardly extending side frame portions 3 and 4 which extend longitudinally the full length of the vessel on opposite'sides thereof. Rigid interconnecting bodies 5 and l are provided at the upper and lower surfaces respectively of portions 3 and 4. The lower part of body 1 is com,-

prised by a longitudinal body 8 which is covered with sheet iron which forms stream, lined por tions 9 and ill at the forward and after extremities of the vessel. I I z i In the side frame portions 3 and 4 are mounted a plurality of floatbearing frames H which are adapted for sliding substantially in a vertical direction (Figs. 5 to 10), These frames support at their lower part the bearings l3 of floats I2, which in the form shown, are cylindrical hollow bodies having partitions l4 forming peripheral cells contiguous to one another in which air is compressed by an effect of inertia of the water" when the vessel- .has attained a predetermined speed at which-time the vessel is lifted relative compressed air and a vertical hydrodynamic reaction.

In the form shown each frame II is constituted by four vertical ribs joined by reinforcing bars 22. A rigid bottom floor I6 is secured to these vertical bars and at the center of the floor is secured a. rod I5 of a piston I8 which moves within a cylinder I9. Beneath floor I6, a bearing support I! for trunnions 29 is provided, said bearings sustaining all the weight of the frames II and a proportional weight of the chassis 2. The chassis is supported by means of a gaseous medium within the cylinders, preferably compressed air which is conducted to the cylindersby conduits 23 and 24. Means for securing each cylinder to the chassis are provided comprising bars 20, 2I which project downwardly into frame II.

In order to facilitate the telescopic motion of a float bearing frame within the side frames 3 and 4, the four vertical ribs of frame Ii are adapted for engaging rollers 4? and 48 (Figs. 5 and 6), eight of the former being journalled in the lower floor 1 (Figs. 5 to '7) and eight of the latter being journalled in an upper beam 45, two rollers engaging each corner or vertical rib at each floor.

The above mentioned conduit 24 constitutes an interconnecting means for all of ie cylinders I9 thereby insuring an equalization of pressure of the gaseous medium therewithin, permitting an outward stroke of one group of pistons and an inward stroke of another group when, for example, the former group is in the trough of a Wave and the latter upon the crest. An inlet tube 25 connected to conduit 24 is provided having communication with a motor driven fluid pump (not shown) and having attached thereto a safety valve 26 and an inlet valve 21. The latter valve may be connected to a pump 65 which is actuated when the vessel sinks into the water a predetermined amount. The pump comprises in. the form shown a piston 65 which by means of a rod 64 is connected to a float 63 situated beneath'body 8. The float 63 comes in contact with the water when the vessel is at rest, at which time the cylinder I9 is close to floor I6.

' Means are provided for operatively connecting float I2 with suitable power means comprising, in the form shown, a gear train within a gear box I3a, which is constituted by a spur gear 28 upon a cylindrical neck 29a of said float. Gear 28 meshes with a pinion 30 which is keyed to a bevel gear 30a. The latter meshes with a second bevel gear 31 to which is secured a shaft 32 having a longitudinal key 33 which extends the length of the shaft. Shaft 32 is keyed to a bevel 35 and is adapted for a sliding motion therethrough. Bevel 35 engages another bevel 38, which by means of a shaft 31 is connected to power means (not shown) through suitable clutch means (not shown).

It is desirable to establish a mean or reference position of the chassis relative to the floats and also to provide means for governing the period of oscillation of the floats as they follow the changing levels of the water. Such means also acts as a return mechanism to restore the abovementioned reference position after the action of thesea or waves has altered the same. These means, in the form shown, comprise a toothed rack 38 secured to the side of the float bearing frame II,.i. e., to bars 22 by means of two vertical rails 39 and 40 (Fig. 8). Rack 38 engages a spurgear M on which is keyed a pinion 42 which in turn engages a spur gear 43. A cam 44 is secured to gear 43 and is yieldingly retained in a predetermined position by means of spring bars which contact said cam on oppoiste sides thereof and which are secured at their upper extremities to the beam 46.

The dimensions of the spring bars 45 are so calculated that the elastic reaction transmitted to the float bearing frame by means of the gear train and toothed rack 38 determines a period of oscillation of from ten to twenty seconds, for example, dependent upon the load borne by the particular piston, so that the framework 2 will have the same period of oscillation (vertical) when said spring bars act in the same direction simultaneously.

The embodiment of Fig. 4 is similar to the previously described embodiments with the exception that the float bearing frames are guided by rollers 41, 48. in a direction inclined slightly to the vertical. This direction is normal to the average acclivity of the largest waves and acts upon the device to reduce the transverse components of the forces applied to the float frames.

In operation the power means rotates the float members which propel the vessel over the water. The float members being yieldingly mounted upon the chassis will follow the motion of the waves or swells whereby the vessel remains substantially stable, thus avoiding a sudden submersion or emersion of the floats. When the vessel is riding a wave its length is sufficient to insure that there is an equal number of ascending and descending floats I2 except when the vessel is parallel to the waves crest. freely from the cylinders of the ascending float frames to those of the descending frames thus permitting a cushioned yielding action of the float frames. The operative connection of the power means to floats I2 remains uninterrupted despite the undulations of the floats because of the sliding shaft 32 which engages gear 35 at all times regardless of the position of the floats relative to the chassis.

When a float frame is displaced from its midposition the cam 44 will distend bars 45 and initiate a yielding return movement of the piston I 8 and the frame to the original position as shown in Fig. 6. 'Each cam is in its position of equilibrium when the volume of the compressed air within the cylinder is such that the pistons are in the middle of their stroke.

The load is borne entirely by the compressed gas in the cylinders and not by the return mechanism when the cam 44 is at the initial or zero position thereof (Fig. 6), a sufficient quantity of compressed gas being contained in the cylinders at this'position of the cam. The return mechanism therefore is relatively lighter, and smaller than is required in road vehicles. The springs 45 tend to create a depression when there is insufficient air or gas in cylinders I9, and, in the contrary case, an'excess of pressure relative to the necessary supporting pressure in the mid-position. When a suflicient number of springs act to produce an excess of pressure the valve 26 will open before the excess of gas will have elevated the frame work 2 beyond a predetermined point.

Because of the action of the yieldingly mounted float members which follow the motion of the The gaseous medium passes "might also be connected to a pump which in turn from striking floor It. A Suitable pump, for example, pump 65 may be kept in operation for this purpose. V I

In Figs. 9 and 10 there is shown ayvariation of the toothed rack apparatus.-- Each float bearing frame is provided with four racks secured to its vertical corners, said racks comprising, for example, railroad rails each of which engages guide wheels 41 and meshes with .a spur gear Me, the latter gear being operatively connected to a return mechanism as described in co nnection with Fig. 6.

Figs. 11 to 13 show'a second form of mounting the floats l2 upon the float bearing frames M. This mounting permits a transverse inclination of the floats and comprises a support ring 49 in which are secured bearings 50 for the trunnions 29. Axially perpendicular to trunnions 29 are bearings 5| in which are journalled trunnions 52 which are secured to a-framework' 53 surrounding the upper half of float l2. Support ring 49 is adapted also for supporting bearings 54 of a bevel gear 55' which engages another bevel 56 keyed to the float.

Gear 55 is connected to a power shaft 6 I, which rotates in a bearing 62, by means of a double universal joint '58, having a shaft 59. Joint 58 is connected to gear 55 by means of shaft 51.

A compression chamber (not shown) may be placed in communication with the conduit system in order to increase the volume thereof, in order to prevent the formation of an excessive pressure, for example, as in the case of a vessel smaller than a wave length where all the pistons 58 would rise suddenly upon encountering a wave. Such a chamber would also diminish the loss of air through valve 26.

A wind from the port side will cause a list to starboard, a submersion of the starboard'floats, and consequently a change of course to starboard. Suitable means may be provided for compensating for this yawing effect comprising, for example, a rudder which may be constituted by a rotatable float similar to float 12 but which may be turned about a vertical axis upon a siutable mounting situated preferably at the rear of the vessel.

Instead of employing a rudder the yawing of the vessel when listing may be compensated by speeding up the overloaded floats'or by employing one or more gyroscopic stabilizers which may be mounted preferably amidship.

There is thus provided a novel vehicle which is especially adapted for use as a marine vessel.

The vessel is capable of high speeds, i. e., from approximately 60 to miles per hour, in heavy seas with almost a complete absence of rolling and pitching. The vessel, furthermore, is easily maneuvered and meets with only a small hydrodynamic resistance as compared to that met by ordinary vessels.

Although only two embodients of the invention have been illustrated and described in detail it is to be expressly understood that the invention is not limited thereto. For example, the apparatus may be employed as a land vehicle as well as a marine vessel, provided suitable changes are made in the rolling surfaces or floats I2 to adapt the same for land. It is also possible to employ the device as a buoyant installation which may be attached to suitable fixed guides, the latter being anchored to the bottom of the sea in such a manner that the float members, which will undulate with the motion of the water, will be able to transfer the energy of the sea swells to suitable power generating means. The valve 21 may be actuated by the axial oscillations of shaft 32 not only while under way but when at rest. Various changes may also be made in the design and arrangement of -the parts withoutdeparting {5 from the spirit and scope of the invention as the same will now be understood by those skilledin the art. For a definition of the limits of the invention reference will be had primarily to the appended claims.
