Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
In a bilge pump, the combination comprising a vacuum body in the form of two (semi)- hemispherical cases opposed (by) at their bigger diameter, a master unbalanced rotating weight with a vertical axle mounted in said cases, a high frequency working water pump driven through a ring an offset wheel connection by said master weight, a ball bearing g oil pump, a second unbalanced weight rotatable about said axle, (an oil bag tearable), a floating ball water valve connected to said water pump, a support holding the second unbalanced weight, and an offset ball bearing support with liner holding the lower end of said vertical axle for causing said axle to operate said oil pump.
Claim 2
Dependent Claim
115 words
In a bilge pump, the combination comprising a vacuum body in the form of two (semi)- hemispherical cases opposed (by) at their bigger diameter, a master unbalanced rotating weight with a vertical axle mounted in said cases, a high frequency working water pump driven through a ring an offset wheel connection by said master weight, a ball bearing g oil pump, a second unbalanced weight rotatable about said axle, (an oil bag tearable), a floating ball water valve connected to said water pump, a support holding the second unbalanced weight, and an offset ball bearing support with liner holding the lower end of said vertical axle for causing said axle to operate said oil pump.
Claim 3
Dependent Claim
21 words
A gravity bilge pump as defined in claim 1 wherein the mechanism actuating the water pump is working under vacuum condition.
Claim 4
Dependent Claim
25 words
A gravity bilge pump as defined in claim 1 wherein the second unbalanced weight swings around its vertical axle to unbalance the master unbalanced weight.
Claim 5
Dependent Claim
38 words
A gravity bilge pump as defined in claim 2 wherein a tearable oil bag is initIally affixed between the two unbalanced weights while the vacuum is created and automatically torn when the said bilge pump starts to work.
Claim 6
Dependent Claim
30 words
A gravity bilge pump as defined in claim 1 wherein said floating ball water valve keeps the water inside the pump inlet pipe when the water level is too low.
Claim 7
Dependent Claim
32 words
A gravity bilge pump as defined in claim 1 wherein a flexible support holding the second unbalanced weight by a screw and spring lets said second unbalanced weight move up and down.
Claim 8
Dependent Claim
31 words
A gravity bilge pump as defined in claim 1 wherein said offset ball bearing support using a liner holds the lower end of the master unbalanced weight''s axle to unbalance it.
Claim 9
Dependent Claim
20 words
A gravity bilge pump as defined in claim 1 wherein the unbalanced weights are hollow and filled with heavy material.
