3,347,202 APPARATUS FOR RELEASAELY CONNECTING A BOAT HULL FITTING WITH A SOURCE OF FLUSHING WATER James E. McCurry, 2171 Nautical St., Anaheim, Calif. 92802 Filed Jan. 21, 1966, Ser. No. 522,102 2 Claims. (Cl. 115.5)
ABSTRACT OF THE DISCLOSURE A removable inverted suction cup which is attachable to a slotted boat hull fitting to direct flushing water through the fitting. The suction cup is connectible to a water hose whereby water is directed into the confines of the suction cup. An upstanding threaded mounting post is vertically slidably supported on the suction cup, with the upper end of the post being formed with a T-head that is greater in length than the width of the slot so that the head may be aligned with and then forced through a The present invention relates generally to boating and more particularly to apparatus for releasibly connecting a boat hull fitting with a source of flushing water.
If the water cooling passages of a motorboats internal combustion engine are not flushed with fresh water after use in salt water the salt water remaining in the passages and lines will evaporate leaving salt deposits. These salt deposits not only corrode metals, but also gradually accumulate to thereby reduce the interior dimensions of the water passages restricting water flow therethrough. The same is true with the bait tank lines of boats operated in salt water. Generally, water cooling passages and bait tank lines are flushed with fresh water by means of a conventional garden hose, such hose being manually supported against the hull inlet fittings leading to the engine or to the bait tank. This conventional operation is tedious, and moreover, considerable water leakage takes place with this arrangement.
It is a major object of the present invention to provide apparatus readily attachable to and detachable from a boat hull fitting to direct flushing water through such fitting.
Another object of the present invention is to provide apparatus of the aforedescribed nature which may be connected to and detached from a boat hull fitting in a minimum period of time and without requiring the use of any tools.
A further object of the present invention is to provide apparatus of the aforedescribed nature which positively remains in position on the hull fitting without any manual support.
It is yet .a further object of the present invention to provide apparatus of the aforedescribed nature that is economical of construction, simple in design and extremely compact.
A more particular object of the present invention is to provide apparatus of the .a'foredescribed nature that includes a resilient inverted suction cup the upper periphery of which is sealingly engageable with the portion of a boat hull adjacent the hull fitting that is to receive flushing water. The suction cup vertically slidably carries an 3,347,202 Patented Oct. 17, 1967 upstanding threaded mounting post, the upper end of the post being formed with a T-head, that is removably insertable within the slot of a hull fitting when such head is aligned with the slot. A coil spring carried by the post between the underside of the T-head and the upper portion of the suction cup constantly biases the post away from the boat hull fitting. A nut is threaded upon the post exteriorly of the suction cup, with tightening of such nut after the T-head has been rotated to a position transverse to the direction of the slot serving to temporarily but securely lock the suction cup in place upon the boat hull.
These and other objects and advantages of the present invention will become apparent from the following detailed description, when taken in conjunction with the appended drawings herein:
FIG. 1 is a side elevational view of a boat provided with a preferred form of apparatus embodying the present invention, such apparatus being arranged in operative position upon a hull fitting of said boat;
FIG. 2 is a perspective view of said apparatus in enlarged scale; and
FIG. 3 is a further enlarged centrally vertical sectional view of said apparatus arranged in operative position upon a boat hull.
Referring to the drawings and particularly FIGURE 1 thereof, a preferred form of flushing apparatus F embodying the present invention is shown secured to the hull fitting 10 of a boat B, such boat being carried upon a conventional boat trailer 12. The flushing apparatus F is adapted to connect a fresh water flushing hose 14 with the hull fitting 10. The hull fitting 10 may be in communication with an internal combustion engine (not shown) mounted within the boat B, or alternatively such fitting may be connected to a bait tank (not shown) carried by the boat B. With the flushing .apparatus F connected to hull fitting 10 fresh water will flow from the hose 14 through the hull fitting 10 to the water passages of the internal combustion engine or to the bait tank in communication with the hull fitting and then out a discharge pipe 16 carried by the boat B in the manner indicated by the directional arrows in FIG. 1.
More particularly and with additional reference to FIGS. 2 and 3 the flushing apparatus F includes a suction cup, generally designated 20, formed of a resilient material such as natural or synthetic rubber. The suction cup 20' is adapted to be arranged in an inverted position with its upper periphery 22 sealingly engaged with the portion of the boat hull 24 adjacent the hull fitting 10. The interior of the suction cup 20 is formed at one of its sides with an integral depending neck 26. The lower end of the neck 26 is provided with a conventional female fitting 38 that is removably engageable with a conventional male fitting 30 secured to one end of the hose 14.
The mid portion of the suction cup 20 is formed with a vertical bore 32 that vertically slidably receives an upstanding externally threaded mounting post generally designated 34. The shank 36 of the mounting post 34 extends through a pair of vertically aligned inner and outer washers 38 and 40, respectively, disposed on opposite sides of the central portion of the suction cup 20. The upper end of the mounting post 34 is integrally formed with an elongated T-head 42. The width of the head 42 should be less than the width of the slots 44 formed in the hull fitting 10. Slid ably disposed upon the mounting post 34 below the T-head 42 is an upper Washer 46. A coil compression spring 48 encircles the mounting post 34 between the underside of the upper washer 46 and the inner washer 38.
Preferably, the lower end of the mounting post 34 is formed with a horizontal fixed indexing finger 50 which is vertically aligned with the T-head 42 to indicate the position of the T-head. Alternative indexing means may 3 also be employed. A wing nut 52 is threaded upon the mounting post 34 below the outer washer 40.
In the operation of the aforedescribed apparatus, the suction cup 20 is secured to the boat hull portion 24 by first aligning the T-head 42 with one of the slots 44 of the hull fitting 10. Thereafter, the mounting post 34 is rotated approximately 90 degrees so as to position the T-head 42 transverse to the direction of hull fitting slot 44 and thereby restrain the mounting post 34 from movement away from the hull fitting 10. Finally, the wing nut 52 is tightened to partially compress spring 48 and thereby maintain T-head 42 tightly engaged with the inside surface of hull fitting 10. In this manner the suction cup 20 and its parts will be positively secured in place upon the boat hull. The position of the T-head 42 relative to the direction of the slot 44 may be readily detected by means of the indexing finger 50.
With the fresh water hose 14 connectedto the lower end of the neck 26 fresh water from the hose will flow upwardly through the interior of the suction cup 20 and then through the slots of the hull fitting 10. To remove the suction cup 20 from the side of the boat hull B it is merely necessary to back off the wing nut 52. Thereafter, the F head 42 is rotated into alignment With the direction of the hull fitting slot 44 to align this head with the slot. The suction cup 20 then may be easily removed from the boat hull.
It will be readily apparent that the aforedescribed flushing apparatus F is easily and quickly attachable to and detachable from the hull fitting 10, and when so ap- 3 plied the suction cup 20 will remain in position without further attention. It will also be apparent that water may be introduced through the hull fitting 10 without any water leakage. The flushing apparatus F makes it possible "for a boat engine to be operated for testing purposes, or while the 'boat is being stored out of the water.
parting from the spirit of the invention or the scope of the following claims.
