Abstract
Abstract A floatable suction head is used with a hydraulic pump and is adapted to float in a body of water such as a settling pond. The floatable suction head is especially adapted for use with a hydraulic pump of the type used in drilling operations, and includes a housing having a bouyant body positioned interiorly thereof, the bouyant body having a ballast chamber therein. The ballast chamber communicates with the inlet and outlet of the suction head and, when filled with water, serves as a counter balance for the weight of the hose connected to the outlet of the suction head. With this arrangement, during operation of the pump, the suction head will float on the body of water in a horizontal level condition.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
A floatable suction head for use with a pump, comprising a symmetrical housing formed of rigid material having a lower wall, a bouyant core within said housing and substantially filling the same, a counter balance ballast chamber in said core material adjacent one side of said housing, a coupling member connected with said housing and being spaced from and opposed to said ballast chamber, said coupling member being connected with one end of an elongate pump-connected suction hose, an elongate passage in said core intercommunicating said coupling and said ballast chamber, an inlet in said lower wall communicating with said ballast whereby water flowing through said inlet will fill said ballast chamber to counter balance the combined weight of the hose, and the weight of water flowing through the hose to thereby permit said suction head to float in a substantially horizontal level condition.
Claim 2
Dependent Claim
144 words
A floatable suction head for use with a pump, comprising a symmetrical housing formed of rigid material having a lower wall, a bouyant core within said housing and substantially filling the same, a counter balance ballast chamber in said core material adjacent one side of said housing, a coupling member connected with said housing and being spaced from and opposed to said ballast chamber, said coupling member being connected with one end of an elongate pump-connected suction hose, an elongate passage in said core intercommunicating said coupling and said ballast chamber, an inlet in said lower wall communicating with said ballast whereby water flowing through said inlet will fill said ballast chamber to counter balance the combined weight of the hose, and the weight of water flowing through the hose to thereby permit said suction head to float in a substantially horizontal level condition.
Claim 3
Dependent Claim
37 words
The floatable suction head as defined in claim 1 wherein said houwing and said core are each of elongate generally rectangular configuration, said housing including opposed side walls, opposed end walls, and opposed upper and lower walls.
Claim 4
Dependent Claim
39 words
The suction head as defined in claim 2 wherein said ballast chamber is of generally rectangular configuration and is positioned adjacent one of said end walls, and said coupling element is connected with the other of said end walls.
Claim 5
Dependent Claim
36 words
The suction head as defined in claim 3 wherein said passage interconnecting said coupling element and said ballast chamber is located adjacent said upper wall and communicates with said ballast chamber adjacent the upper portion thereof.
Claim 6
Dependent Claim
35 words
The suction head as defined in claim 3 wherein said inlet is spaced from said ballast chamber and is interconnected therewith by a passage which extends upwardly from said inlet and longitudinal of the housing.
Claim 7
Dependent Claim
26 words
The suction head as defined in claim 5 wherein the vertical dimension of said housing is substantially less than either the width or length dimension tHereof.
