3,049,088 DRAIN FOR BOATS Gerald J. Curtis, 8806 Glen Loch, Houston, Tex. Filed Get. 31, 1960, Ser. No. 66,231 4 Claims. (Cl. 114-197) This invention relates to a device for draining water out of boats, and more particularly to a drain plug and valve device adapted to be inserted in the drain opening of a boat, and which operates automatically to permit the outflow of water from the boat and to prevent the inflow of water through the drain opening.
The invention has for an important object the provision of admin for boats which is operated by the suction or radtiction in pressure which takes place in the water rearwardly of the stern of the boat due to forward movement of the boat in the water to cause an outflow of water from the boat, and which is also constructed to prevent any inflow of water into the boat through the drain.
Another object of the invention is to provide a boat drain device, which is formed in one piece of resilient material and which is designed to be easily installed in the drain opening of a boat in a manner to close the opening against any inflow of water therethrough but which allows water to flow out of the boat through the device.
A further object of the invention is the provision of a drain device of the character mentioned adapted for insertion through a drain opening in a boat and which is constructed to be used in drain openings of widely different sizes and on boats having diiferent wall or transom thickness.
Another object of the invention is to provide :a boat drain formed of flexible, resilient and stretchable material having a tubular portion which is inset-table through a drain opening in a boat and externally enlarged annular portions on the tubular portion which are positioned for sealing engagement with the inner and outer surfaces of the boat surrounding the drain opening to securely close the opening against the leakage of Water through the opening externally of the tubular portion.
A further object of the invention is the provision in a boat drain of the type mentioned of closure means which is insertable in the tubular portion of the device to close the same and including means on the closure and tubular portion positioned for coaction to resist removal of the closure therefrom.
Another object of the invention is to provide a boat drain device which is of simple and rugged construction, economical to manufacture, easy to install and which is effective in operation to exclude the inflow of water into the boat from the exterior while functioning readily to allow water to dnain out of the boat.
The above and other important objects and advantages of the invention may best be understood from the following detailed description, constituting a specification of the same, when considered in conjunction with the annexed drawings, wherein- FIGURE 1 is a fragmentary side elevational view, partly broken away and partly in cross-section illustrating a preferred embodiment of the invention and showing the same in its operative position extending through a drain opening in a boat;
FIGURE 2 is a top plan view of the device of the invention, :as shown in FIGURE I, removed from the boat;
FIGURE 3 is a fragmentary, side elevational view, on an enlarged scale, of the rear end portion of the device of the invention showing details of structure of the same; and
FIGURE 4 is a rear end view of the device as illustrated in FIGURE 3.
Referring now to the drawings in greater detail, the invention is illustrated herein in connection with its use on a boat having a wall portion W, through which a drain opening 0 is provided for the purpose of drawing water out of the boat. Such opening is customarily located in the transom of the boat at or close to the bottom of the boat or in the bottom of the boat so that the water will be substantially completely drained out of the boat, due to the suction created by forward movement of the boat. Various means are customarily provided for preventing the 'backflow of water into the boat through such drain openings, such as stoppers, check valves, or the like, which are subject to leakage or accidental removal, and it is for the purpose of overcoming such difliculties that the present invention has been developed.
The drain device of the invention comprises a gen erally tubular body formed of tough, elastic stretchable material, such :as rubber, or the like, having a portion 10 of cylindrical shape in cross-section, which is adapted to be inserted through the opening 0, and formed with longitudinally spaced, externally enlarged, annular portions 12 and 14, which are tapered to provide converging faces 16 and 18, respectively, positioned for engagement with the Wall W about the inner and outer end portions of the opening 0 to close the opening against the leakage of Water past the body externally thereof.
The body has a flattened portion or tail 20, extending from one end of the cylindrical portion 10, formed with thin flexible walls 22 and 24, which are spaced apart throughout the major portion of their lengths and which are in contact throughout the outer end portion of the body as indicated at 26.
Each of the walls 22 and 24 is formed with a hollow, tapered, external rib 28, extending outwardly from the externally enlarged portion 14 and shaped to somewhat rigidify the wall and to yieldingly resist movement of the spaced apart portions of the walls into contact with each other.
The externally enlarged portion 12 of the body is provided with an internal annular groove 30, positioned to receive an external annular rib 32 formed on a stopper 34, when the stopped is inserted in the body to close the body. The rib 32 is engageable in the groove 30 to securely hold the stopper in the body against accidental removal. The stopper 34 is attached to the body by means of a flexible strip 36 to hold the stopper in a convenient location for insertion into the body when it is desired to closethe drain device.
The entire drain device of the invention may conveniently be formed by molding in one piece of suitable resilient and stretchable material, such as rubber, or the like, so that it will be adapted for use with boats having widely differing wall or transom thicknesses and in which the drain opening 0 may vary substantially in diameter.
In installing the device in the boat, the body may be folded longitudinally and inserted through the opening 0, whereupon the cylindrical portion 10 may be pulled into position in the opening with the externally enlarged portions 12 and 14 located beyond the ends of the opening and the tapering faces 16 and 18 in sealing engagement with the wall W at the ends of the opening, the stopper end 12 of the device being positioned in the boat and the tail portion 20 extending rearwardly therefrom outside of the boat. With the drain device thus installed, suction caused by forward movement of the boat will tend to draw water from the boat through the cylindrical portion and tail of the body, such outflow of water resulting in separation of the wall portions 22 and 24 at the outermost end portion 26 of the device. Upon cessation of the forward movement of the boat, however, the pressure of the water on the external surface of the tail portion 20 will force together the wall portions 22 and 24 at the outermost portion 26 to close the device against the inflow of water therethrough into the boat. The outermost portion 26 of the device will ordinarily be closed, but due to the separation of the wall portions 22 and 24 forwardly of the portion 26, due to the rigidifying, hollow ribs 28, any tendency for Water to flow outwardly through the device will easily open the portion 26 to permit such outflow.
The drain device may be manufactured by molding the same of elastic, resilient material, using an inner core shaped to form the cylindrical portion 10, ribs 28 and spaced apart wall portions 22 and 24, the core being very thin between the wall portions 22 and 24 in the end portion 26. After the device has been removed from the mold and the core withdrawn, the edge portions of the tail portion 26 may be slitted or removed and the wall portions 22 and 24 pressed together throughout the length of the portion 26 and vulcanized or other-wise joined along their edges as indicated at 38, so that the device will be closed against the flow of fluid therethrough through the portion 26. By so forming the drain device of the invention, the device will be normally closed against inflow of water into the boat, but will readily open to permit outflow therethrough.
In the event that the drain device should be damaged or leak, or when it is desired to leave the boat afloat for long periods, the stopper 34 may be inserted to assure that there will be no accidental inflow of water.
It will thus be seen that the invention, constructed and installed as described above, provides a boat drain device which is of simple design and rugged construction, which is affective to allow outflow of water from the boat while preventing inflow and which is capable of application to boats having widely differing wall thicknesses and various drain opening diameters.
The invention is disclosed herein in connection with a certain specific embodiment of the same, but it will be understood that this is intended by way of example only, and that various changes can be made in the structure of the device within the spirit of the invention and the scope of the appended claims.
Having thus clearly shown and described the invention, what is claimed as new and desired to secure by Letters Patent is 1. In a boat drain a tubular body shaped to be extended through and outwardly beyond a drain opening in a boat and having externally enlarged portions positioned for engagement with the boat at the inner and outer ends of the opening to close the opening against the fiow of fluid therethrough exterally of the body, Said body having spaced apart wall portions formed of flexible material located outwardly beyond the opening and formed with body also having wall portions located outwardly beyond external longitudinally outwardly tapering ribs, said body also having wall portions located outwardly beyond said spaced apart wall portions whose inner faces are in contact to close the body against the inflow of fluid therethrough and movable apart to open the body under the influence of the pressure of fluid in the body when said pressure exceeds the pressure of fluid on said wall portions externally of the body.
2. In a boat drain a tubular body shaped to be extended through and outwardly beyond a drain opening in a boat and having externally enlarged portions positioned for engagement with the boat at the inner and outer ends of the opening to close the opening against the flow of fluid therethrough externally of the body, said body having spaced apart wall portions formed of flexible material located outwardly beyond the opening and formed with external, longitudinally extending, hollow ribs, said body also having wall portions located outwardly beyond said spaced apart wall portions positioned for coaction to close the body against the inflow of fluid therethrough and to be moved apart to open the body under the influence of the pressure of'fluid in the body when the pressure of fluid on said wall portionsexternally of the body falls below the pressure of fluid in the body.
3. In a boat drain a tubular body formed in one piece of elastic material shaped to be extended through a drain opening in a boat in sealing contact with the boat in the opening to close the opening against the flow of fluid therethrough externally of the body, said body having wall portions located outwardly beyond the outer end of the opening positioned for coaction to close the body when the pressure of fluid externally of the body on said wall portions exceeds the pressure of fluid in the body, each of said wall portions being formed with an external longitudinally extending, hollow rib, whose interior is in communication with the interior of the body.
4. In a boat drain a tubular body formed in one piece of elastic material shaped to be extended through a drain opening in a boat and having externally enlarged portions positioned for engagement with the boat at the ends of the opening to close the opening against the flow of fluid therethrough externally of the body, said body having oppositely disposed flat wall portions located outside of the boat positioned to be held in contact to close the body under the influence of the pressure of fluid outside of the boat on the exterior of said wall portions when such pressure exceeds the pressure of the fluid inside of the body on said wall portions, and means formed integrally with the body and shaped to be removably inserted in the body to close the body.
