BOAT.
Application filed November 19, 1917. Serial N 0. 202,709.
To all whom it may concern:
Be it known that I, FRANK O. MITTAG, a citizen of the United States, and a resident of Park Ridge, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Boats, of which the following is a specification.
The invention resides in a novel type and construction of power-driven boat.
One object of the invention is to provide a boat of very staunch construction and capable of attaining a high speed. A furproduction of a high speed boat which will ride steadily through and to a large extent on or over the surface of the water and have no tendency to turn over. 'Another purpose of the invention is the production of a boat which although comparatively wide and long may be turned or deflected from its course quickly and within a short space.
In carrying out my invention I make the hull of the boat comparatively wide, as distinguished from the narrow sharp-pointed types of high-speed boats, and except for a curved bow my boat presents, preferably, when viewed in top elevation, an oblong outline, the longitudinal lines of the sides of the hull being parallel and straight and the transverse line of the stern being straight. The bow portion of my boat is of special construction in that it is preferably convexly curved along its upper forward lines, that its bottom extends downwardly and rearwardly and more particularly that said bottom is formed with two plain side sections of comparatively narrow width and between said sections with a wide downwardly and rearwardly extending concave section which starts at the bow and finally merges into the lines of the main bottom of the boat. My construction of bow results in the forward portion of the boat riding up out of the water when the boat is in motion, thereby minimizing friction and resistance, and also in the boat riding steadily and safely. In rear of the how I provide the bottom of my boat with a number of vertical fins or blades arranged longitudinally and in' staggered order and these fins or blades aid in steadying the boat and facilitate the short-turnin or deflection of the same. I also prefera 1y provide horizontal fins or plates at the opposite'sides of the rear end of the boat and close down to the'bottom of the boat. The -'propeller-shafts issue through the bottom of the boat and the propellers are preferably below the rear end of the boat and are submerged when the boat is 1n use. a v
The invention will be fully understood Fig. 5 is a like-section through the same taken on the dotted line 5-5 of Fig. 3;
Fig. 6 is a top view, partly broken away, of the interior framing within the forward portion of the boat;
Fig. is a view partly in section and partly broken away and partly in side'elevation of a portion of the rear part of the boat, the section being on the dotted line 77'of Fig. 5'; v i
Fig. 8 is a front elevation, partly broken away, of the interior framing at the bow of the boat, and
Fig. 9 is a front elevation of the boat.
Inthe drawings, 10 designates the opposite sides of the boat, 11 the bow, 12 the stern, 13 the usual steering wheel, 14 the rudder, 15 the engines, 16 the propeller shafts, 17 the propellers on the rear ends of said shafts, 18 fins or blades secured to the bottom 19 of the boat, 20 lateral fins 01' plates secured "to the sides of the stern of the boat and in near relation to the bottom thereof, 21 a compartment having seats 22 for passengers or crew, and 23 a compart-,
ment having a seat 24 for passengers or per: sons using the boat.
The sides 10 are preferably parallel and straight, and the stern 12 is transverse and preferably straight.
The bow 11 is covered over or'has a deck 25, and the upper front portion of said bow is on convexlines, as shown.
The bottom construction of the bow of the boat is of special importance, and said bottom extends downwardly and rearwardly and comprises two side sections 26 and a concave section 27 (Figs. 2 and 9), which is. between and wider than the sections 26. The sections 26 curve downwardly and rear- Specification of Letters latent. Patented Feb. 25,1919. 7
wardlyand merge into the fiat bottom 19 of the boat, and the concave section 27 starts well up at the front of the bow and-extends downwardly and rearwardly and finally merges into said bottom 19.
The bottom 19 connects the sides 10 and extends rearwardly from the bow-sections or blades 18 secured thereto, therebeing three rows ofsaid fins or blades, instaggeredrelation,onthe main portion of said bottom and two rows of said'finson said section 28. v
I have found the fins or blades 18 to be of considerable. importance in a boatof the construction presented; by me, in that they aid in steadying the boat and keeping it on its course and also permit of the turning of the boat within a short space. The fins 18 on the upwardly offset portion 28 ofthe bottom of the boat are particularly useful in a boat of my construction, because. when this boat is in use the bow, ridesupwardly and the stern to a certain extent submerges, and at this time the; fins 18 on said bottom section 28 act to steady the stern of the boat and aid in guiding the boat on -its course. The.,,-latera-lly projecting fins .or plates 20 secured to the opposite sides of the stern of the boat and near the bottomthereof cooperate with the general construction of the boat inavoidin rockin of the boat and also cooperate wlththens 18 in facilitatingthe keeping-ofthe boat on a straight course oron such course as nay be imparted to itfromthe rudder.
The i terior of the boat 's composed of staunch framing to which the outer planking orcoverlng is applied, and in Figs, 4:
and SI indicate theinterior framing of the bowportionof the boat, this construction being also to, a certain extentindicated by dotted lines, in Figs, 1 and 3. In the interior of the bow portion of the boat I provide a: series of upper ancllower transverse beams numbered, respectively, 29, 30 whose outline is represented in Figs. 4 and 8 The beams 29, 30 are .secured at their ends; to vertical ams 3 n t e r mi p io hey are connected by vertical. beams 32, said beams 31,, 32varyingin length from-the extremebow portion of the boat toward the compartment 21, The vertical beams 31, 32 are connected together-wherever conven- 1e nt and possibleby crossed timbers 33 (Fig. 4
The upper:- and lower beams 29, 30v are, adgacent,,to,.,the.;beams .31, connected together by vertical beams 34, and these beams 3l are connected together by longi tudinally extendingbeams 35. I also con- .nect the vertical beams 31 by means of longitudinal beams or bars 36, and from the short forward vertical beam 32 (Fig. 8) I extend brace beams 37 which, .as indicated'by dotted lines in vFig. 1, are secured to and diverge rearwardly from the said forward vertical beam 32 and at their rearendsare securedto the vertical beams 34:. The construction just described may vary, but it is one which has proven to be desirableand results in a bow construction ofvery strong and durable character and capable of withstanding the treatment to which it is subjected when the boat is in actual use, I preferably arch the upper beams 29, and the lower beams 30 are concaved in their middle portions so as to create the bottom side sections 26 and bottom concave section 27, a
which portions, as hereinbefore described,
extend downwardly and rearwardly to about in line with the front endiofthe compartment 21. V V
r The interior structure of those portions of the boat at the rear of the bow portion may vary but preferably will comprise vertical bars or ribs 38, transversebeams 39, long1- tudinal beams'lO set upon said transverse tending downwardly and inwardly from the vertical members 38 to the transverse'beams 39 and secured-t0 said vertical and transverse members, as shown in Fig. 5. The braces 41 arepreferably mortised in the vertical beams 38 and on the transverse beams 39 and bear upon the longitudinal timbers or beams 40 I-also, as shown at the righthancl side of Fig. 6, employ additional longitue; dinal, transverse, diverging and vertical members, but these need not be specifically explained since they may vary with the determination or will of the builder ofthe boat, My boatis of special exterior outline, and have described the essential portions of; the
- beams 39, and angularly set braces ll .ex-
skeleton frame to receive the outerplanliing that the boat constructed as describedmay employ engines 15 of'high H. e Am ng th purp s s rl' h eaccQmpHshed i-my en tru ion f b atis theat nment of high speed, steady and safe riding, and
capability of short turning or deflection within limited space. My construction of boat also permits me to use engines of high H. P. and to minimize friction and resistance, all this being true even though the boat of my invention 1s comparatively broad as distinguished from high speed boats having sharp pointed bows and which otherwise lack the characteristics of my boat.
What I claim as my invention and desire to secure by Letters-Patent, is:
1. A boat of the character described hav ing arallel vertical sides from how to stern, a su stantially straight stern, a slightly for wardly arched bow-line, a main flat bottom and a bow portion which extends downwardly and rearwardly and comprises two parallel flat side sections and an upwardly concaved intermediate section and which sections merge into the flat bottom of the boat adjacent to the bow portion of the boat, and which boat is provided at its stern with propelling means.
2. A boat of the character described having parallel vertical sides from bow to stern, a substantially straight stern, a slightly forwardly arched bow-line, a main fiat bottom and a bow portion which extends downwardly and rearwardly and comprises two parallel fiat side sections and an upwardly concaved intermediate section and which sections merge into the flat bottom of the boat adjacent to the bow portion of the boat, and which boat is provided at its stem with propelling means, said flat bottom having at the stern of the boat an upwardly ofi'set section, and. said propelling means comprising propellers which with their shafts are below said upwardly ofi'set section of the bottom.
3. A boat of the character described having parallel vertical sides from bow to stern, a substantially straight stern, a slightly forwardly arched bow-line, a main flat bottom and a bow portion which extends downwardly and rearwardly and comprises two parallel flat side sections and an upwardly concaved intermediate section and which sections merge into the flat bottom of the boat adjacent to the bow portion of the boat, and
which boat is provided at its stern with propelling means, said flat bottom in rear of said bow portion having a series of vertical fins spaced apart both longitudinally and transversely considered.
