Abstract

Abstract A body defining a cylindrical passage receives a wire rope to be cleaned. An annular orifice extends about the wall of the passage and cooperates with a supply chamber for supplying pressurized fluid to the orifice. A duct between the chamber and the orifice directs fluid against the rope and is angled at more than 45* with respect to the axis of the passage.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 227 words
A tool for cleaning or treating wire rope comprising: a. a body defining a cylindrical passage along which passes the wire rope to be cleaned or treated; b. the diameter of at least a portion of the passage corresponding to the nominal gauge of the rope with only a small clearance substantially less than the gauge of the rope; c. a supply chamber in the body for supplying pressurized fluid; d. an annular duct terminating in an annular orifice extending around said portion of the passage coupling the supply chamber to the orifice for conveying the fluid; e. the duct being defined by the space between the portions of the body with closely spaced frusto-conical surfaces so as to be inclined at the orifice end towards the end of the passage at which the rope enters, the angle defining the inclination between the axis of the passage and the duct being greater than 45* and less than 90*; f. said body being split in a plane containing the axis of the passage to define two similar body halves; g. removable means holding the body halves in their assembled relationship; and, h. means attached to the removable means to enable the body halves to be quickly separated in the event the rope should become blocked in said portion of said body where only said small clearance is provided.
Claim 2
Dependent Claim 227 words
A tool for cleaning or treating wire rope comprising: a. a body defining a cylindrical passage along which passes the wire rope to be cleaned or treated; b. the diameter of at least a portion of the passage corresponding to the nominal gauge of the rope with only a small clearance substantially less than the gauge of the rope; c. a supply chamber in the body for supplying pressurized fluid; d. an annular duct terminating in an annular orifice extending around said portion of the passage coupling the supply chamber to the orifice for conveying the fluid; e. the duct being defined by the space between the portions of the body with closely spaced frusto-conical surfaces so as to be inclined at the orifice end towards the end of the passage at which the rope enters, the angle defining the inclination between the axis of the passage and the duct being greater than 45* and less than 90*; f. said body being split in a plane containing the axis of the passage to define two similar body halves; g. removable means holding the body halves in their assembled relationship; and, h. means attached to the removable means to enable the body halves to be quickly separated in the event the rope should become blocked in said portion of said body where only said small clearance is provided.
Claim 3
Dependent Claim 20 words
A tool as claimed in claim 1, in which said removable means includes hinge means having a removable snatch pin.
Claim 4
Dependent Claim 26 words
A tool as claimed in claim 1 wherein the angle of inclination of the duct with respect to the axis of the passage is substantially 60*.
Claim 5
Dependent Claim 32 words
A tool as claimed in claim 1 wherein the one of said frusto-conical portions which includes the acute-angled rim of the orifice is part of a removeable wear bush in the body.
Claim 6
Dependent Claim 17 words
A tool as claimed in claim 1 wherein the width of the duct is substantially 0.020 inch.
Claim 7
Dependent Claim 21 words
A tool as claimed in claim 1 wherein the entry end of the passage is flared outwardly away from the orifice.
Claim 8
Dependent Claim 25 words
A tool as claimed in claim 1 wherein the passage terminates at the entry end in a cross-bore from which air-suspended material is carried away.
