J. KESSLER BOAT PROPELLING SYSTEM Filed Au 31, 1952 INVENTOR JOHANNES KESSLER BY ATTORNEY Patented Apr. 18, 1933 V 7 i Application filed August 31, "Seria I 631,213.
This invention relates to propulsion sys tems for advancing boats and has as an object to provide a power operated device for producing water suction at one end of the boat BOAT rnornnni'r reisvsrmlr f JonANNEs KES'SLER, or IoNd IsLAn'nfoiriY; was i v extend asstraight spaced tubesfQO' to outlets 21in the 'boat'sides near'the stern; aspl'a 'ly i 1 shown.

5 and to deliver the water at the other end 7 through tubes secured in the hull of the boat. rear Afurther feature is in theprovision of two 25. I i V i i longitudinally extending tubes, arranged in The forwardly extending -portionsof the" spaced relation inthe hull, below the water shafts 24 pass throughstufiingboxes 260mm,, L 7

to support hearings-23 for shatts 24 was in spaced relation and'ea'ch'provided with an independently driven screw propeller, either of which may be actuated separately, in either direction, or driven in unison, as may be desired. 1
Finally it is a'purpose of the invention to produce an eflicient system of boat propulsion in which the propellers are housed centrally in the length of: the tubes being thus prevented from becoming damaged by contact with objects in the water.
These advantageous objects are, attained by the novel construction and arrangement of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a side elevational view of a con ventional type of dispatch or pleasure boat, showing an embodiment of the invention as built therein.
Figure 2 is a top plan View of the same. Figure 3 is a transverse sectional view taken on line 33 of Fig. 1, and drawn to an enlarged scale. 7 u
The hull 10 of the boat is shown to be of stream line design, provided witha seat 11,
These engi nes .a 2e independent of each other, so that one or both may be driven'in either direction, or in opposite directions, as.. in turning, effectively and materially assist-'1 in r the operation of the rudder 14.
Tt is to be noted that thearea of the tube elements 17-18, is in excess of the area/of the delivery tubes 21, so that a full water supply is obtained. V
'Due' to the symmetry of the arrangement, the small spaceoccupiedand the efficiency obperformance is highly advantageous. V i
Obviously a single central tubeniight be" i used in place of the pair shown, or even in' combination with them and it isto be noted 5 that no Wash? :orebulition of the water is i i set up, therefor being particularly valuable v,
in canals.
made within the scope of the invention,"it is intended that all matter contained in the foregoing description or shown in the accompanying drawing shall be'interpreted as illustrative and notin a limiting sense.
The boat shown in the drawing is for pur-. pose ofillustration only, the system is not re-' stricted thereto however, but may be, used for all water vehicles Letters Patent, is
1. A boat having tubes extending longiis tudinally throughout the lengths of its hull in spaced relation and below the water line, a screen at the bow entrance to said tubes,-
propellers rotatably mounted substantially centrally in the length ofsaid tubes, and/independent motors coupled to' eaich ro 11 IDO v 1.
. '80 As changes in the construction could be i Having thus described the invention, what .is claimed as new and desiredto be secured by 52; 7 "l; a 1,904,792 f gl-LI-J i said motors being inset froin the forward V A portions .of said tubes.
V 2. A'boat havlng apair of tubes extending longitudinally within its bull in close relation 5 thereto in the forward part of the boat, and
having parallel extensions of lesser area open "at the stern, an engine alined with each extension, shafts from the engines passing through ,stufling lboxes into the tubes, and propellers V 7 fixed on said shafts to cause a forced 1 m he 7 tion of watertli-rough said tubes:
, 3. A boat: having tubes extendlng longia tudinally within its hull in spaced relation 7 1 and below the water line in a substantially 15 level plane, said tubes'having openings spaced'uniformly at theiropen forward ex- 7 tremities and {closely following the hull to a point amidship, thereafter extending in par- 7 7 allelic-their open rear vends at the stern, a 1
screen at the entrancejof said tubes, engines I disposed adjacent the forward e portions of tubes to aline with the parallel portions thereof, andprop llers intermediate the lengths of said tubes driven by said engines. 7
In witness whereof I have signedmy name to this specification.
