A. DELANEY WAVE-ACTUATED BOAT PUMP Filed April 13, 1962 Feb. 4, 1964 l l H'L /A/z/EA/ra@ 14K NaLZJ .DEL A/vg y 'fi-f" United States Patent 3,126,212 WAVE- ACTUATED BGA? PUM? Delaney, Sor/ernment Road, Nords Wharf,
New South Wales, Australia Filed Apr. i3, i952, Ser. No. 187,333 Clair?" priority, application Ausraia Apr. l?, 1961 6 (Cl. 114-133) rhis invention has been devised to provide a boat pump adapted for attaching to a hull on the outside when a boat is moored. The pump incorporates a lioat a1'- ranged so that waves or movement of the boat will cause the Float to actuate the pump. The pump is particularly devised to remove water from the bilge of unattended small craft.
This Wave actuated pump comprises a plunger pump, means for removably attaching the pump to the outside of a boat hull, means connecting the plunger oi the pump to a .Float in the water in s ch manner that the plunger is reciprocated by the lloat due to wave movement or boat movement, and a pump suction pipe is extended into the boat bilge. Preferably the pump barrel is open on the discharge side and is so located that it is automatically maintained primed.
@ne embodiment of the invention is described with reference to the annexed drawings wherein:
FIG. l is a perspective View of the invention attached to the outside of a boat hull.
FG. 2 is an elevation of the invention with parts of the pump and the attaching means shown in section and with part of the attaching means broken away.
As illustrated, the pump consists of a pump barrel 1 having a sludge sump 2 at the bottom thereof, an inlet connection 3 above the sump 2, and an outlet 4 at the top. A valve seat 5 is iixed in the pump barrel l above the inlet 3 and has a foot Valve 6 to register therewith. A plunger 7 in the pump barrel l has a valve seat 8 formed therein and a head valve 9 seats thereon.
ri`he plunger rod l@ is connected at one end to the plunger and at its other end it is connected to a lever l. The lever il is connected at one end to a oat l2 and its other end it is ulcrumed as at 13 to a bracket fixed on and projecting from an offset limb l5 of base member le. The bracket Je has a screwed opening E7 in the bottom thereof and the pump barrel 1 is mounted in the opening i7, which is also in communication with outlet 4. The bracket 14 also has spaced limbs 18 thereon which, with the body of the bracket 14, provide side guides and upper and lower stops for the lever il. The base member i6 as illustrated, is removably mounted on a mounting plate l@ Which is fixed to the outsi e of the boat hull 29.
The iioat i2 is saucer shaped and has a line edge 21. The float "r2 is so constructed that it is normally submerged to a suicient degree whereby the edge 2l Will minimise side loading on the lever ll due to wave movement. The plunger is reciprocated by the float due t0 wave movement or boat movement.
A flexible pump suction pipe 22, preferably formed from a plastic material such as polytnene, is connected at one end to the inlet 3 and has its other end located in a bilge of the boat.
I claim:
l. A wave-actuated boat pump comprising, a barrel having a closed bottom and an open top, said open top forming an outlet in said barrel, means for removably attaching said barrel to the outside or" a boat, an inlet to said barrel adgacent said bottom for receiving a ilexible inlet pipe, a foot valve in said barrel above said inlet, a plunger in said barrel above said foot valve and having a head valve therein, a rod carried by said plunger and projecting from said open top o said barel, a float adapted to ride on the surface of the water, movable means connecting said float to said rod, whereby relative motion between the surface of the water and the boat causes vertical movement of said float to actuate said plunger.
2. Wave-actuated boat pump according to claim l wherein the pump outlet is located below Water level for the purpose of maintaining automatic priming.
3. Wave-actuated boat pump according to claim l wherein the tioat is a saucer-like vessel constructed to be substantially submerged.
4. A wave-actuated boat pump according to claim 3, wherein, said float is provided with a line peripheral edge adapted to ride upon the surface of the water.
5. A wave-actuated boat pump according to claim 1, wherein, said movable means comprises a lever fulcrummed at one end on said attaching means and having its free end connected to said float.
6. A wave-actuated boat pump according to claim 5, wherein said attaching means includes a bracket having side guides and upper and lower stops to limit the movement of said lever.
