water, ice or snow and more particularly to ways and means-to enable such amachine to arise and fly up from the 'water, ice or snow into the airwhich constitute a valuable improvement upon the construction shown in my former patent of February 23, 1909, and numbered 913,515. The desirability of such a device is well known, andmuch effort has heretofore been made to accomplish it, but owing to the great suction and adhesion of the water to the ship, it appears thatthe greater the power that .is applied on "the lines of present practice the greater becomes the suction and adhesion.

The main object of this invention therefore, is to obviate or alleviate this suction by providing means for introducing and main taining a layer or body of air or gas between the water and the floatable bottom of the ship with sufiicientforce and volume to repel the water from suction, 0r adhesivecontact with the under surface of the ship, thus breaking the suction and relieving the frictional resistance of the water, and whereby greater speed is readily obtained; to auxiliate and supplement the aerial propeller in the propulsion of the ship, by providing means for utilizing the waste energy of the exhaust gases from the motor together with energized air projected in a current of elastic fluid that is directed rearwardly between tlfie water and the bottom surface of the s 1p.

A further object is -to auxiliate and assist the planes of a ship in performing their function of lifting and supporting the ship, by the use of rarefied and expanding air projected in the form of elastic fluid under the ship while in motion; to provide means ,to enable the ship to run 'up' out of water upon and over ice and snow, and to ascend there-from into theair orv tjolrun from ice or snow into .water without danger of in jury to person or property, which obviously means a very valuable acquisition to the art of navigation and the saving of lives andv property in'times of drifting ice, and finally to "connect the water and aerial rudders to ef fect a combined steering movement when run-ningjo'n the water, without the use of 1mdesirable extension of the water rudder below thebottom of the ship.

invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in-the accompanying drawings, and pointed out 1n the cl'alms hereto appended, it being understood that various changes in the form,

proportions, and size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Upon the accompanying two sheetsof drawin'gs forming ajpartof; this specification, similar characters of reference'will be found to designate like or corresponding arts throughout the several figures, an of wh1ch proved shipcomplete, except that a part of the bow and stern are broken away to better show their construction.

Referring in detail to the characters of reference marked upon the drawings 10 represents the body of the ship which as will be noted is of the usual general elongated shape 'though"provided with a fiat bottom. Immediately beneath the bottom or floor of the bow of the. boat I provide a compartment 11 that extends across the width of the boat,- and is-providecl with a contracted discharge opening 12 at its rear and lower end. A series of keels 13 extend along the central portion of the bottom of the ship from bow to stern in a way .to strengthen and support the bottom, and

more especially to form longitudinal channels 14 beneath the ship and intermediate of its bottom, and the water. The outer or side 'keels 15 are formed slightly deeper than the .intermediate keels, but like the latter run the full length of the ship in a Withithese and other objects in view. the

way to properly support the edge portions I provided with an exhaust manifold with an open air intake '17, in its forward end and through which the air is conveyed past the several exhaust nozzles 18 from the respec-: tive cylinders and together conveyed through the pipe 19 to the compartment 11 where the said exhaustand air is discharged and directed beneath the ship through the several channels'in a way to not only tend to force the boat forward, but upwa'rd as well, producing a displacement of the ves-" sel in the water and lessening the resistance of the ship when in motion;

The two outer keels 15 are'each provided with arunner or shoe 20 upon which the forward portion of the ship rests and which together with the rear runners 20,.'on"'rudders 21 pivotallyconnected to the body,

serve to support and guide the ship. when.

. the same is being operated on snowg'or ice. In addition to the features befor'e 'described for lightening the welght of the ship upon. the water by the use ofjthe exhaust:

ases from the motor employedfto drive the s 1p, 1 provide a series of airplanes so constructed and arranged as to coiiperate with the elastic fluid and further impart a lift- .ing tendency to the shipwliendriven at high speed, and 1n fact whereby the ship -may be made to clear the water entirely,

' thus making it possible to v rise from thewater into theair. In connection with the air planesl also. employ two adjustable rudders one'of which is designed to raise and lower; the craft'while the other permits it-to -he guided to the right or left. This lattenirudder'is connected to be 015-. erated simultaneously with the'rear rudders 21 and serves to'assist in directing the line of travel ofthe ship whether in the water or upon thesnow or ice.

To the body of the ship is secured a frame. work 23 which includes a series of vertical, crosswise and longitudinal braces that are formed of pipe or wood, and serve to support the lateral steering rudder 22.

as well as the two main air planes 2& and 25 which as will be noted are inclined from front to rear in a way to tend'to lift the craft up when driven rapidly against the air.

The ship as constructed isprovided with a single propeller 26 which is mounted upon a longitudinal shaft 27 journaled in the before mentioned frame 23 and provided with a chain 28 connected to the motor 18,.and whereby the said propeller may be operated againstthe air very rapidly to-drive the craft forward. a

The aerial rudder for raising and lowering .the ship consists of a triangular ,75 shaped jshieldhinged at 3.0 tothe frame, and having its forward end connct'ed j with' a Tape 31 for raising and lowering asper dotted lines (see Egg-5.)] said-rope guide roll 32 and likewised'own and under the lower rolls 33 and then f're arw a connect with the operating lever 34 at 35 to a suitable part of the;, bod

From this operating lever 39 the ropes age carried rearward, one from the upper and the other from the lower end portion of the lever, and directed around the guide rolls ll-located in each side of theboat and connect'edEintermediate. of said guiderolls to the'operating or handle end of the rudders 21. inya way to insurethem moving together and; simultaneously {with they movement of the'lforw' rd lateral steering rudder 22.

instant the motor is ,starte'di theijpropeller is rotated against the air in'a;way to force; the ship forward, the exh'aust gases from the motor together with. the airgf taken into the rearward under the bow of the ship and through the several channels thus giving the boat a forward and upward impulse. Withthiscondition it will be apparentthat the will readily rise therefrom and that the faster the ship is traveling, the greater the blast of gas beneath the ship and consequently the greater the tendency of the ship to leave the water or ice dverwhich it mayv 120 be traveling. 1

Having thus described my inventionwhat I claim and desire to secure by Letters'Pat-. ent, is-

combination with a ship, ofa motor contained therein, means for creating a current of intermingled air and-gases by directing the discharge of the exhaust gases from the cylinders directly into and through a mixing 139 being carried up, over and around a; central 50 v From t e foregoing it will lie-seen that the exhaust pipe is at the same time discharged 11 o ship rests but lightly upon the water and 1.
