'Ihe present invention relates to improvements in means for -removing water from boats and more particularly to the provision of a bailer in the underside of a boat through which water is automatically drained when th boat is in motion.
General objects of this invention are to provide anautomatic bailer which may easily and quickly be installed in a boat and which, at the same time, embodies a simple, practical construction which will be rugged and durable in use, and which may be manufactured and assembled with comparative economy.
With these and other objects in view, the invention consists in certain novel features of construction and combination and arrangement of parts as will be more fully hereinafter set forth and pointed out in the claims, reference being had to the accompanying drawings forming a part hereof, wherein like -numbers refer to like parts.
In the drawings:
Figure 1 is a sectional view of the new boat bailer taken along lines v1-1 of Figure 3; j p
Figure 2 is a sectional view of a boat bailer attached to a fragmentary section of the boat with parts of the boat bailer removed; Y
Figure 3 is a top plan view of the new boat bailer;
Figure 4 is a top plan view of the evacuator plate; A Figure 5 is a top plan view of means remotely controlling the new boat bailer; and,
Figure 6 is a side view of the remote device for controlling the boat bailer with a portion of the boat bailer shown in broken lines.
The common practice in the installation of boat bailers of the self-bailing type is to bore or drill a hole in the underside or bottom of the hull of the boat. This hole is usually located near the center line and as near the stern as possible. This hole, while it may vary slightly in size, for general description could be stated to be threequarters of an inch in diameter.
The objective is to provide means of readily opening this hole when it becomes desirable or necessary to remove water, technically knownl as bilge water, from the boat and to provide a means of quickly closing this hole when the water has been drained.
lForward speed of tive miles per hour or more is required to draw the bilge water from the boat out through `the boat bailer.
The instant action boat bailer consists of a drawn brass or the like valve housing with three feet-like plates drilled for attaching the housing permanently to the inside of the hull and directly on center over an opening.
The mechanism is activated by the valve lifting handle which is attached by means of a locking pin to a valve lifting stem. The valve lifting stern is inserted through a neoprene or like material valve plug with a pressure Valve activating spring placed between the inside of the valve housing and the valve plug.
To place the instant action boat bailer in action, the valve lifting handle is raised to the vertical position and, being an eccentric, it in turn raises `the valve plug to the ICC open position. When the valve plug is in the open posi-- tion and with the boat travelling forward at a speed of, or in excess of, ve miles per hour, the bilge water will be drawn out of the hull through the bailer.
To close the instant action boat bailer through which the bilge Water has been drawn out of the boat, the valve handle is simply flicked down, that is, to the original horizontal position, and the pressure spring automatically closes and seats the valve plug into the opening in the hull, stopping the flow of water either way.
Referring to the drawings in detail, the numeral 10 is used to designate the bottom of a boat having an opening 20 therein and having valve seat 14 suitably secured to the boat about the opening 20. On the outside of the boat is secured evacuator plate 12 having sloping channel therein. The channel 40 is preferably in the form of an arc `of a circle. The valve seat '14 is provided with openings which will cooperate with the openings 42 in the evacuator plate 12 in securing the feet 118, valve seat 14 and evacuator plate '12, in place separately; that is, the plate 12 to the boat, the valve seat 14 to the boat, and the feet 18 to the valve seat ring.
The housing 16 is threaded for reception of removable top 34 and openings A15 are provided between legs of the housing 16. The legs are bent at substantially right angles to the legs to provide feet 18. Valve stem 26 passes through valve plug 22 and top 34. Positioned between valve plug 22 and top 34 is spring 24 which normally urges the Valve plug outwardly from the housing 16. The upper end of valve stem 26 is drilled to provide opening 28 through which lock pin 30 extends in. securing valve handle 32. The valve handle includes substantially bifurcated circular portion generally indicated at 38, ilat nose portions 314 which provide space 33. The handle 32 is secured off center of the portion 38. Y
To place the bailer in operating position the handle 32 is raised until the portions 31 rest upon the top 34. The raising of the'V handle raises thervalve plug 22 against the spring 24 placing the interior of the boat in communication to the outside of the boat through openings 15 between legs extending f-rom body 16, opening 20 in boat, and channel 40. When the valve plug is in the open position just described with the boat travelling at the proper rate of speed, the bilge water is drawn out of the hull through the bailer.
On movement of the valve handle downwardly the pressure Ispring 24 automatically seats the valve plug on the valve seat X14 closing hole 20 in the hull.
The diameter of valve plug 22 is greater than the diarneter of the hole 20. The nose of valve plug 22 extends into hole 20 when in the closed position. The valve plug may be made of suitable material such as neoprene or the like.
The valve stem 26 being eocentrically attached to portion 38 of handle 32 requires only a light touch to cause the release thereof. This action makes it easy to use remote control for opening and closing of the bailer. Figure 5 is an arrangement that permits remo-te control. Encircling band 46 is secured around body 16 by means of adjustable member 48. Pivotally attached to band 46 at 58 is bail 50. Attached to bail 50 and extending from one of the pivots 5S is arm 52. Secured to arm 52 and extending, for example, to the forward part of the boat is cable S4. Valve lifting handle 32 of the bailer extends through member `56 or rests in a slot therein.
The arrangement of part of the bailer in the manner shown insures that the bailer will not foul with sand, dirt, or other materials in the bilge water. By way of example a cylindrical member, such as brass tubing, in a length of about 21/2 inches long has three sections removed to provide legs about 1 inch in length. The three legs are bent at their free end to form feet by which the bailer is s) secured to the boat. Betwen the legs are openings through which the bilge water flows when being removed from the boat. The valve body should extend substantially perpendicular :to the boat bottom.
