Underwater rotatable tool equipment

Claim 2

A fluid pressure actuated driving means for an underwater power tool comprising: a body having a pressurized fluid receiving chamber therein; conduit means for delivering pressurized fluid to said chamber; a fluid actuated member in communication with said chamber to receive pressurized fluid therefrom; means for exhausting said fluid to impart movement to said member; said fluid exhausting means including a plurality of fluid dispensing nozzles communicating from the interior of said member to disperse fluid into the ambient water outside of said member; said nozzles being canted so as to impart tool actuating movement upon emergence of pressurized fluid therefrom.

Claim 3

The device of claim 1 wherein the pressurized fluid comprises environmental fluid.

Claim 4

The device of claim 1 wherein the fluid actuated member in communication with the fluid receiving chamber is mounted for rotational movement.

Claim 5

The device of claim 3 wherEin the fluid actuating member is provided with pressurized fluid discharging nozzles tangentially mounted to impart rotary movement to said member.

Claim 6

The device of claim 1 wherein a portion of the pressurized fluid is emitted in a direction opposite to the direction of tool approachment to the work to thereby urge the tool into work approachment.

Claim 7

Equipment for working underwater with a rotating tool comprising, flexible conduit means for supplying fluid under pressure, a submergible, manipulatable, unitary tool connected to one end of said conduit means, said unitary tool comprising rigid means having a pressurized fluid receiving chamber in communication with said conduit means, a fluid actuated member having a central chamber with an inner fluid entry end in communication with said chamber to receive pressurized fluid therefrom and closed at its outer end by an end wall, fluid-tight means rotatably supporting the inner end of said fluid actuated member on said rigid means, tool-carrier means mounted on said outer end wall of said fluid actuated member and rotatably driven by the same, and means for exhausting said fluid to impart rotational movement to said member, said fluid exhausting means including a plurality of fluid dispensing nozzles located between said rotatable supporting means and said tool-carrier means and communicating with the central chamber in said member to disperse fluid therefrom into the ambient water outside of said member, said nozzles being canted so as to impart tool actuating movement to said member upon emergence of pressurized fluid therefrom.

Claim 8

Equipment for working underwater with a rotating tool comprising, flexible conduit means for supplying fluid under pressure, a submergible, manipulatable, unitary tool connected to one end of said conduit means, said unitary tool comprising rigid means having a pressurized fluid receiving chamber in communication with said conduit means, a fluid actuated member having a central chamber with an inner fluid entry end in communication with said chamber to receive pressurized fluid therefrom and closed at its outer end by an end wall, fluid-tight means rotatably supporting the inner end of said fluid actuated member on said rigid means, tool-carrier means mounted on said outer end wall of said fluid actuated member and rotatably driven by the same, and means for exhausting said fluid to impart rotational movement to said member, said fluid exhausting means including a plurality of fluid dispensing nozzles located between said rotatable supporting means and said tool-carrier means and communicating with the central chamber in said member to disperse fluid therefrom into the ambient water outside of said member, said nozzles being canted so as to impart tool actuating movement to said member upon emergence of pressurized fluid therefrom.

Claim 9

Equipment as defined in claim 6, including a plurality of guide members carried by said fluid actuated member so as to be associated with the jets of fluid discharging from said nozzles, said guide members being configured to provide openings level with the discharged jets of fluid and permitting the free evacuation of such jets into the ambient water.

Claim 10

Equipment as defined in claim 6, in which the discharge openings in said nozzles are each in the form of an elongated narrow slot having its greatest dimension disposed parallelly to the axis of rotation of said fluid actuated member.

Claim 11

Equipment as defined in claim 6, in which the discharge openings in said nozzles are each in the form of an elongated narrow slot having its greatest dimension disposed transversely to the axis of rotation of said fluid actuated member, said discharge openings being constructed and arranged to produce a thin circular jet in a plane disposed at right angles to such axis of rotation.

Claim 12

Equipment as defined in claim 6, including a deflecting plate mounted on said fluid actuating member between said fluid dispensing nozzles and said tool-carrier means, said reflecting plate extending beyond the discharge openings in said nozzles and being configured so that the fluid jets discharging through such openings apply a thrust thereon in the direction of said tool-carrier means.

Claim 13

Equipment as defined in claim 10, including means for supporting said deflecting plate for free rotational movement relative to said rotatable fluid actuating member.

Claim 14

Equipment as defined in claim 6, including a hood mounted on said unitary tool and enclosing the discharge ends of said fluid dispensing nozzles, a portion of said hood in the region of said nozzle ends being grated to permit the fluid jets discharged from said nozzles to pass therethrough, such grated portion of the hood being constructed to cause such jets to lose sufficient of their kenetic energy so that they do not appreciably disturb the water bottom.

Claim 15

Equipment as defined in claim 12, including means rotatably supporting said hood on said unitary tool to permit free rotational movement thereof relative to said nozzles.

Claim 16

Equipment as defined in claim 12, in which said hood in the region of said nozzle ends has a deflecting section located between said nozzle ends and said tool-carrier means, said grated portion of said hood being locaTed on the other side of said nozzle ends.
