BOAT BAILER Filed Nov. 15, 1948 Patented Nov. 21, 1950 UNITED STATES PATENT OFFICE Claims.

In the operation of power driven boats, the seepage of water into the boat is quite a problem. While the boat may be perfectly water-tight when floating at the dock, the vibration of the motor, when the boat is being driven, has a tendency to open the seams slightly permittin water to enter. Even if the boat is tight when moving the spray often enters the boat so that the floor becomes wet and the inconvenience spoils the pleasure of the ride. As the prow of the boat is usually raised when traveling, the water invariably flows to the back of the boat.

The object of the present invention is to provide means for removing the water from the boat by the vacuum created from the revolving propeller of the motor.

A further object of the invention is to construct the device such that it will not be injured.

by the collection of weeds around the propeller.

A further object of the invention is to construct the device in a very simple and inexpensive manner and designed such that it will offer very little resistance to the passage of the water therepast.

A further object of the invention is to design the device such that the pipe through which the boat water is passed will never collapse but be maintained open at all times.

A further object of the invention is to provide means for regulating the bailin capacity of the device so that the water can be removed quickly from the boat or regulated to remove the water as it comes in, or it can be shut off entirely.

A further object of the invention is to design the device as an attachment so that no alteration is required to the boat or the motor.

With the above important objects in view, the invention consists essentially in the construction and arrangement of parts hereinafter more particularly described, reference being had to the accompanying drawings in which:

Figure 1 is a section through a boat, equipped with an outboard motor, and showing the invention attached thereto.

Figure 2 is a perspective View of the bracket and reinforcing wire.

Figure 3 is an enlarged horizontal sectional View taken on the line 33, Figure 1, and showing the rear tubing in position and in clotted outline.

Figure 4 is a vertical sectional view taken on the line 4-4, Figure 3, showing how the reinforcing wire enters the rear tubing and reinforces same.

Figure 5 is an enlarged horizontal section through the valve and showing how the tubings are connected.

In the drawings like characters of reference indicate corresponding parts in the several figures. A boat is generally indicated by the reference numeral l and the rear end thereof is provided with an outboard motor 2 which, in Figure l, is

shown in the lower or operating position. All such outboard motors are provided with a downwardly projecting streamlined vertical blade or skeg 3 through which the driving mechanism passes for power transmission to the propeller indicated at 4. It will be noticed that the propeller is positioned to the rear of the skeg 3 so that in the operation of the motor the skeg cuts through the Water ahead of the propeller and protects same against damage by collision; The cross-section of this skeg is shown by the crosshatched portion in Figure 3. Should weeds or other trash collect on the propeller, the motor can be tipped up at the back of the boat to expose the propeller and the space between the propeller and the skeg permits plenty of clearance so that the removal of such weeds is comparatively simple. The principle of the invention now to be described merely consists of interconnected flexible tubings 5 and 6 having one end in the boat for the entrance of water therein and the other end positioned adjacent to the propeller so that the suction therefrom will draw the Water out of the boat.

A comparatively heavy wire 7 is bent in a V- shape as indicated in Figure 2. The two ends of the wire are threaded, as at 8, while the bent portion thereof is rounded, as at 9 so that it conforms to the profile of the skeg over which it fits. This is clearly shown in Figure 3. A second wire H) (see Figure 2') is bent in a long fiat loop and is received over the threaded ends of the wire 1 so that it acts as a keeper or a clamp against the enlarged rounded end of the skeg. One end ll of the wire I0 is cut off short while the other end [2 loops around the end I I as indicated at l3 and then passes forwardly and upwardly in a curve as indicated at I4.

The above mentioned two wires 1 and ID are positioned on the skeg as shown in Figure 3 and suitable nuts l5 are screwed onto the threads 8. When tightened up they bend the clamp I 0 around the large end of the skeg as shown at I6 thus firmly securing the wire to the skeg. When tightened in position, the corners of the nuts catch between the wires of the clamp [B which prevents them from unscrewing while the excess threaded portions 8 are nipped off with a cutter as indicated at I! which burrs the ends and further prevents unscrewing.

From the above it will be seen that the wire i is secured firmly in place on the skeg 3 so that it cannot move and forms a firm bracket to support the curved wire 14 which is in front of and slightly off center from the propeller 4.

The tubing 5 is preferably formed from synthetic rubber or plastic as such material is not affected by oil or gasoline. This tubing has a hole 18 punched in the side thereof slightly in from the lower end. The extending upper end of the wire i4 is passed through this hole into the tubing and the tubing is then slid theredown until the hole [8 is received by the upper portion of the loop 13. By observing Figure 4, it will be seen that the Wire I4 is positioned on the bottom of the passage through the tubing and as it projects up inside the tubing it will lay against the front inner wall. The lower end of the tubing projects past the bracket formed by the Wire 7 and is positioned directly in front of the propeller, adjacent the periphery of its travel so that the maximum suction is acting thereagainst. In actual practice, the tubin is made slightly longer and when so attached is cut off in a position where it just misses the propeller blade.

The upper end of the tubing 5 is pressed over the corrugated ends of a well known rotary cylinder shut-off valve 19 which is suitably positioned on the back of the boat. The other end of the valve is also corrugated and receives the end of the tubing 6 which is the same as the tubing 5. The lower end of the tubing 6 is suitably secured by a clamp 26 to the boat so that the end is close to the bottom of the boat for the entrance of water therein.

In operation the suction from the propeller creates a partial vacuum in the tubes 5 and 6 so that water is drawn from the rear interior of the boat and is discharged into the water passing the propeller blades. The rate of flow can be regulated by the valve 19. The water passing under the bottom of the boat strikes the tubing 5 and accordingly presses the front portion against the wire M. This wire amply reinforces the tubing, keeps it in position at all times and yet forms very little obstruction for the passage of water down the tubing. As the bracket and clamps are formed from wire and the tubing is round, very little resistance is offered to the passage of water under the boat and accordingly the speed restriction is slight. Should weeds entangle in the propeller blades and collect, such collection of weeds will strike the end of the tubing and as it is flexible, it will move sideways, offering no resistance, and accordingly does not become damaged. When the motor is swung up out of the rod or to clear the weeds, the tubing 5 flexes to permit this movement and when the weeds have been cleared its flexibility brings it back into position in front ofv the propeller. By this arrangement, the water can be bailed quickly from the boat, either when it is traveling over the water or when the motor is operated at the wharf. If the water is slowly coming into the boat the valve H! can be regulated so that the water is bailed out as fast as it is coming in. Under such operating conditions, if the water is bailed out slightly faster than it is coming in, the slight amount of air sucked into the tubings will not alfect the speed of the boat to any great extent. On the other hand, if the water is being bailed at full capacity from the boat and air passes through when the water has been bailed, the sudden slackening of speed, due to air getill 4 ting in front of the propeller, will notify the operator and this will remind him to shut off the valve. Accordingly, the valve will seldom, if ever, beleft open when the boat is stopped so obviously the water will not be able to syphon back into the boat.

While I have shown the device as attached to an outboard motor, it is well known that most small inboard operated boats have a skeg similar to 3 on the bottom thereof in front of the propel-ler.-v Accordingly, the same clamp could be used on this skeg, the tubing passed under and over the rear end of the boat in the same manner as shown in Figure l and so used for inboard motors as well as outboard. The bracket and clamp, of course, will be made the correct size to fit the under skeg.

While I have shown the wire 12 as an extension from the loop I3, the wire l0 could be cut off at the loop and the wire [2 could be formed as an extension of the end I I. The wire l2, with the curve [4, would work in the same manner but the tubing would be positioned farther away from the skeg 3. This might be advantageous in certain installations.
