mum of water friction;

Third, to provide a boat of this class in which all the decks and cargo space are positioned above the water line;

Fourth, to provide a boat of this class in'which the propeller mechanism is positioned between two buoyant streamline floats thereby providing a maximum capacity for propelling mechanism;

Fifth, to provide a boat of this class in which there are mounted propellers at both bow and stern of the beat and may be provided with additional propellers intermediate the ends if desired;

Sixth, to provide a boat of this class in which the propellers and propeller shaft are readily accessible for repair or change;

Seventh, to provide a boat of this class in which the shaft and driving mechanism that is submerged is enclosed in a casing;

Eighth, to provide a boat of this class in which the joints are doubly sealed by a rubber cement 30 supported by metallic tanks under pressure, and

Ninth, to provide a boat of this class which is verysimple and economical of construction, durable, efficient in its action, easy to operate, buoyable and non-sinkable.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly 40 set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application, in which:

Figure l is a top or plan view of my boat show- 45 ing some of the parts and portions broken away to facilitate the illustration; Fig. 2 is a sectional view through 2-2 of Fig. 1 showing some of the parts and portions in elevation to facilitate the illustration; Fig. 3 is a front elevational view of 50 my boat; Fig. 4 is a fragmentary side elevational view intermediate the ends showing a portion of the outer surface broken away; Fig. 5 is a fragmentary sectional view on an enlarged scale through 55 of Fig. 1; Fig. 6 is a fragmentary 55 sectional View on an enlarged scale showing the joint filled with rubber cement of one side of the main float runner section shown in Fig. 5; Fig. 7 is a sectional view through 'I'I' of Fig. 2, and Fig. 8 is an enlarged sectional view of the propeller shaft and casing through 8-8 of Fig. 2.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The float runners I and 2, metal tanks 3, rub ber cement 4, upper deck 5, lower deck 6, rudders I, shaft 8, shaft supports 9, propellers Ill and I I, propeller guards I2, sprocket and chain casing I3, sprockets I4 and I5, chain I6, and power plant I'I, constitute the principal parts and portions of my non-sinkable boat.

The float runners I and 2 are streamlined at both bow and stem to reduce to a minimum the friction when passing through the water. They are preferably composed of planks about twelve inches wide and of'suitable thickness and may be covered with steel plate on the outer surface and their sides are secured together by a plurality of cross partitions Ia and 2a, as shown best in Fig. 4 of the drawings. Mounted in these runners I and 2 and filling the space between the partitions are metallic tanks 3 which are adapted to fill the space between the sides of each of these members I and 2 and between the partitions Ia and 2a. These tanks 3 are provided on their outer surface with a rubber cement 4 and are sufiiciently yieldable that when air pressure on the interior of the tanks 3 is provided the cement 4 is forced out through the cracks between the planks forming the side walls of the members I and 2 and filling the joints and also filling the space between the tanks and its enclosing walls, thus providing means for making the joints tight throughout the whole of the submerged portion of the boat. Pressure is provided for the tanks by means of valves 30!. which are used for the entrance of compressed air into the interior of the tanks 3. Thus it will be noted that the tanks are supported on all sides by means of planking secured to the cross partitions and these supports form the float runners I and 2.

The partitions Ia and 2a extend upwardly above the upper sides of said runners l and 2 and these runners I and 2 are positioned in considerably spaced relation to each other and parallel to each other, as shown best in Figs. 1 and '7 of the drawings, and are supported in this relation by means of cross members 5a secured to these partitions and extending from one runner to the other, as shown best in Fig. 1 of the drawings. These members are provided with a plurality of cross braces 51), thus rigidly supporting the members I and 2 in their parallel spaced relation to each other.

At the upper side of the members I and 2 is provided a lower deck 6 which covers the full space including the width of the members I and 2 and at the upper side of the members 501. is provided the upper deck 5 which covers the whole upper surface.

It will be here noted that any kind of housing may be supported over this upper deck 5 as desired for the different uses or purposes to which the boat may be put.

It will be here noted that the lower deck 6 extends upwardly on an angle at Get at the bow of the boat to conduct the Water under the lower deck 6 in a series of high waves or the like.

The boat is propelled through the water by means of propellers l0 and I! mounted between the float runners l and 2, preferably two of these propellers, one near the bow and the other near the stern. They are supported by means of a shaft casing 8a, shown best in Fig. 8 of the drawings, which shaft casing is supported by means of the supports 9 which are provided with bearings Set for supporting the ends of the shaft casing 8a. Mounted inside of the shaft casing 8a is a journal 8b for supporting the shaft, it being noted that there is a plurality of these supports 9 and each of them is bifurcated upwardly some distance above the shaft and above the normal water line and the ends extend in through the lower deck 6 and are secured to the partitions la and 2a between the decks 5 and 6, as shown best in Fig. 5 of the drawings.

It will be here noted that other propellers may be mounted on the shaft 8 intermediate the propellers Ill and II if desired for increasing the propulsion power of the boat.

Secured to the casing 8a is a sprocket and chain casing I3 which is shaped as shown best in Figs. 2 and '7 of the drawings and adapted to enclose the lower portion of the sprocket and chain for operating the shaft. Mounted on the shaft 8 in said casing I3 is a sprocket l4. Mounted on this sprocket I4 is a chain I6 which extends up through the decks 5 and 6 and is mounted on a sprocket I5 in connection with the power plant H.

The supports 9 are supported relatively to each other by braces 91). Mounted in front of the propeller II are propeller guards l2 one at each side of the propeller and extending from the upper deck 5 downwardly on an angle and then backwardly and secured to the lower portion of the front support 9, as shown best in Fig. 2 of the drawings. These are for the purpose of providing a guard against floating objects striking the propeller.

Mounted on the rear of the boat between the float runners I and 2 and on opposite sides of the rear propeller ID are tandem rudders which are for the purpose of guiding the boat and are positioned on opposite sides of the propeller in close relation thereto to provide for efliciency in propelling the boat.

It will be here noted that cargo may be placed between the decks 5 and 6 or in some cases some cargo may be placed in the tanks 3. However, it is highly desirable that sufflcient bulkhead space be provided to float the craft and cargo regardless of its position and to float it if one or two of the tanks are damaged so that they leak and fill with water or partially fill with water.

It will also be noted that additional tanks may be secured between the members I and 2 if desired to provide additional buoyancy in case of heavy loading. It will be noted that tanks may be placed in the space between the decks 5 and 6, if desired, in case of heavy loading.

Though I have shown and described a particular construction, combination and arrangement s of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a non-sinkable boat, a pair of streamlined float runners in parallel spaced relation to each other, spaced decks bridging said float runners and holding them in their spaced relation to each other, said decks connected at their sides and ends forming a hollow, closed buoyant hold, said float runners being hollow and each provided with a plurality of transverse partitions, and tanks filling the hollow spaces in said float runners, said tanks covered with rubber cement adapted to fill the joints and leaks in said float runners around said tanks.
