INBOARD MOTOR BOAT Filed May 9, 1960 2 Sheets-Sheet l IN V EN TOR.
b'gar I; $210129 United States Patent 3,010,423 INBOARD MOTOR BOAT Le Roy B. Sanders, Palmyra, Pa. (Box 555, Lebanon, Pa.) Filed May 9, 1960, Ser. No. 27,694 9 Claims. (Cl. 11535) This invention relates to inboard motor boats, and particularly to the instrumentalities through which they are driven and steered.
As is well-known, inboard motor boats utilizing the conventional propeller and drive-shaft possess numerous, and serious, disadvantages. Primarily, they lack safety, due to poor control. The control-and consequently the maneuverabilityof boats of this type is relatively poor in general, but is extremely poor when reversing the boat, or trying to dock it across running tides or cross winds. In reverse, the jet stream is forced in a forward direction against the bottom of the boat, defeating, to an appreciable degree the attempt to move the boat rearwardly.
In addition, conventional inboard motor boats are easily damaged. Both their steering and propulsion mechanisms can be, and frequently are, ruined by going aground or by striking submerged objects, thus completely incapacitating the boat.
Leakage in inboard motor boats is common, due to loosening of bolts, etc., from the vibration of the drive shaft.
It is among the objects of the present invention to provide a novel and improved inboard motor boat which will not only eliminate all of the characteristic disadvantages of inboard motor boats set forth hereinbefore, but which provides other advantages as will be described hereinafter.
Another object is the attainment of the immediate foregoing in a manner which is both simple and inexpensive.
More especially, the present invention makes completely unnecessary a number of troublesome and expensive parts that make up the conventional equipment in present day usage to propel and to maneuver inboard boats,
(1) That portion of the drive shaft which is disposed underneath the boat, together with the bushing and stufiing box which are supported by a large and shaped brass housing and base plate, with its twenty or more brass screws and packing, required by the shaft as it passes diagonally through the keelpiece;
(2) The strut which supports the lower portion of the shaft and propeller, and the through-the-hull and keel bolts attaching it to the hull. Frequently, leakage occurs at this point due to vibration of the shaft;
(3) The strut bushing which also is a major source of trouble, whether composed of brass, fibre or rubber. No lubrication of this bushing, other than water, is practical, so any sand or dirt getting into it quickly causes wear, thus necessitating the installation of a new bushing. On a sand bar, this bushing can be ruined by sand in a matter of but a few minutes;
(4) The strut skeg;
(5) The rudder and rudder shaft, with their throughhull fittings and bolts or screws; and
(6) The stuffing box and the bolts or screws holding it, which is another area that requires frequent checking for leaks, etc.
It is manifest that repairs to all of the aforementioned parts require either drydocking, raising the craft, or diving underneath.
The present invention seeks to replace the aforementioned submerged propulsion and control items of conventional design with a combination of elements which are assembled as a unit, all of which may, by a single operator alone and with but a few simple tools, be quickly 3,010,423 Patented Nov. 28, 1961 Fee and easily repaired from wholly within the boat and above water level.
Briefly stated, the present invention contemplates the provision of a unit composed of a pair of box-like elements in substantially close telescopic disposition, the outer element being almost, but not quite, bottomless with its lower end stationarily secured to the bottom of the hull, and in substantially flush relationship therewith. The inner (and removable) box-like element is provided with a closed bottom which is closed except for an apertured through which the propulsion and control elements extend, the same being rotatable from above, and preferably take the form of the lower end of the lower leg of a conventional (rudderless) outboard motor unit.
A boat constructed in accordance with the teachings of the present invention, as briefly described hereinbefore, may be not only repaired in the manner described hereinbefore, but so maneuvered as to permit the boat to be docked across running tides or cross winds. Also, steering is completely controllable so that the boat may be readily turned in a complete circle and/or the angular position of the propeller changed to to permit reversing the boat without reversing the drive-shaft. It will, of course, be understood that a reasonable amount of care must be exercised in order to avoid the possibility of overturning the boat at relatively high propeller speeds.
To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but several of various ways in which the principle of the invention may be used.
In the annexed drawings:
FIGURE 1 is a side elevational view of a boat which embodies the teachings of the present invention;
FIGURE 2 is a plan or top view.
FIGURE 3 is an enlarged fragmentary elevational view, partly in section, and taken on the line 33 of FIGURE 2; and
FIGURE 4 is a sectional view taken on the line 4-4 of FIGURE 3.
Referring more particularly to the drawings, the numeral 2 generally designates the outer box-like element or housing of the apparatus of the present invention. This outer housing or well 2 is constructed of suitable material, such, for example, as non-corrosive metal (i.e., bronze, etc.), marine plywood, etc., and may be of any desired shape, rectangular in most cases being preferable, not only because of ease of manufacture, but also from the standpoint of having it becoming a part of, and lending additional strength to, the bottom of the hull of the boat.
The size of the outer housing or well 2 (and, accordingly, that of the telescopically disposed inner housing) may, of course, considerably vary, depending upon the size of the boat, etc. However, it may be stated that, for a small boat of 20 to 30 feet in length, the outer rectangular housing may acceptably be approximately 16 inches long, approximately 14 inches wide and approximately 10 inches deep.
The outer surface of the outer housing 2 is shown as provided with a right-angularly extending peripheral flange 4 which is disposed adjacent to, but spaced u-pwardly from, its bottom and which is stationarily secured to the inner surface of the bottom of the hull 6 of the boat and closely adjacent the stern thereof. While keelpiece lag bolts or wood screws maybe utilized for this purpose, riveting and/ or welding, etc., will probably prove preferable when both the hull 6 and the flange 4 are composed of compatible materials.
The present invention also contemplates, wherever necessary or desirable, gasketing between the hull and the outer housing 2 and/ or the use of suitable caulking compounds. 7
Referring to FIGURE 3, the outer housing 2 is provided with a bottom portion 8 having an opening 10 therein. The said bottom portion 8 maysimply comprise a right-angular flange extending inwardly from the lower end of each of the walls of the housing with the adjacent ends of the flanges connected together, if
desired. On the other hand, the bottom portion 8' of the outer housing 2 may take the form of a floor having therein an aperture of substantial size. 3
' However, it is essential to the teachings of the present invention that the opening 10 in the bottom 8 of the outer housing 2 be of such size and shape as to permit passage therethrough of the lower portions of the steering column, drive shaft and propeller'mechanism of the boat.
The inner housing of the apparatus of the present invention-is generally indicated at '12 and, as before stated, it is of such size and shape as will permit it to assume relatively close telescopic relationship within the outer housing 2 with its lower end resting on the upper surface of the'bottom of the latter.
As shown in FIGURE 4, the inner housing 12 has a e floor or bottom 14 provided with an aperture '16 which preferably is much smaller in area than the opening 10 in the bottom of the outer housing 2, but which communicates therewith. To the underside of the floor or bottom 14 of the inner housing 12 there is secured a reinforcing plate 15 which has approximately the same configuration as the aforementioned opening 10 in the outer housing 2, thereby providing a smooth and uninterrupted underside.
The top of the inner housing 12 carries a peripheral flange 18 which extends outwardly at right-angles and a similar flange 20 is carried by the outer housing 2 at a position which is therebelow.
-It will be observed that the flanges 4 and 20 (carried by the outer housing 2) and the flange 18 (carried by the inner housing 12) are all shown in the drawings as comprising simple angle-irons which are secured in their respective positions by welds X, which very materially strengthens the units to which they are attached.
It will also be noted that the angle-iron which forms the peripheral flange 18 at the top of the inner housing '12 has, its depending leg portion disposed within the latter, thus providing an uninterrupted outer. surface which telescopes closely within the outer housing 2.
The outwardly extending flanges 18 and 20 are provided with bores which align with one another, and through which there extend suitable interconnecting fastening instrumentalities, such as machine screws 21 and nuts 22, the latter. of which may, if desired, be
welded to the bottoms of the flange 20 to facilitate quick detachment and reassembly.
.According to the foregoing construction and arrangement, the inner housing 12 may be forcibly drawn down into the outer housing 2; and a compressible gasket 25 of suitable material is disposed between their respective bottoms.
The numeral designates a vertically disposed tubular housing whose lower end is secured to the bottom 14 of the inner housing 12 and which communicates with the aperture 16 through a suitable water-tight bearing 32.
A drive shaft 46 is concentrically disposed in the tubular steering column'36 and is operatively connected in conventional manner (i.e., through bevel gears, wormand-worm gear, etc.) to the propeller shaft 42.
Thus, it will be seen that both the driving of'the propeller 44 and the rotative adjustment of the steering column 36 by which the propeller is carried are controllable either from within or through the intermediary of the interior of the inner housing 12.
In the event it is desired to steer the boat from a point which is relatively remote from the inner housing 12, one of its side walls and the immediately adjacent portion of the side wall of the outer housing 2 are intercommunicatingly apertured, as at 48, to permit the passage therethrough of any conventional control media which may be operatively connected with the tubular steering column 36. For example, the tubular steering column 36 may, as shown in FIGURES 3 and 4, be provided with a ling gear which meshes with a pinion secured to a shaft 49, the latter projecting through the said apertures 48 and carrying a (steering) rope pulley, etc.
Correspondingly, intercommunicating apertures 50 may be provided in the walls of the inner and outer housings for the passage therethrough of a power drive shaft 52 which is operatively connected to the drive shaft 46, as by means of a'bevel gear arrangement within a gear box 53 which is mounted atop the vertically disposed tubular housing 30. The forward end of the drive shaft 52 is shown as connected to a marine engine 54 which may, if desired, be disposed amidship.
From the foregoing, it will be perceived that the apparatus of the present invention provides greater safety in the handling and maneuverability of a boat upon which it is installed through (1) The ability of the operator to swing the propellers axis of rotation through acomplete circle or at least through a wide arc; and
(2) The elimination of a rudder.
Additional safety while afloat is provided by the ability of the operator of the boat to quickly and easily detach and remove the inner housing 12 and all of the aforementioned instrumentalities which are connected therewith simply by unscrewing the'machine screws 21 and disconnecting the elements which operate the tubular steering column 36 and the drive shaft 46; thereby enabling the repair or replacement of any part of the propelling and steering mechanisms from wholly within the boat and above water level.
This is particularly important in the case of comparatively small boats which are frequently operated by persons whose strength isquite limited.
While I have shown and described certain specific embodiments of the present invention, it will be readily understood by those skilled'in the art that I do not wish to be limited exactly thereto, since various modifications 7 'may be made without departing from the scope of the in- A- tubular steering column 36 is disposed concentrically in, and extends downwardly through, the tubular.
'The lower end of' the tubular steering column 36 carries a housing 40' which rotatably supports a rightangularly extending propeller shaft 42 having a propeller 44 secured to its outer end.
