Abstract
This invention relates to an apparatus (10) for cleaning a helical member (52) such as a tabulator blade. The apparatus comprises opposed scrubbing brushes (32, 34) for removing deposits from the helical faces of the helical member (52) as it is passed between opposed bristles of the scrubbing brushes (32, 34). The opposed scrubbing brushes (32, 34) are mounted with the apparatus via a rotatable bearing (12) such that as the helical faces are reciprocated between the brushes, the continuously curving profile of the helical member (52) causes the brushes to rotate. Accordingly, the opposed scrubbing brushes (32, 34) maintain good contact with the helical surfaces thereby simplifying and improving the removal of deposits.
Claims19
Apparatus for cleaning a helical member, the apparatus comprising a first scrubbing member having a working surface adapted to remove deposits from a first helical face of a helical member passed thereover, the first scrubbing member being rotatably mounted on the apparatus such that, as the first helical face of the helical member is reciprocated over the first scrubbing member, the first helical face causes the first scrubbing member to rotate such that a working surface of the first scrubbing member remains substantially in contact with the first helical face to thereby remove deposits from the first helical face of the helical member.
A method of cleaning a helical member, the method comprising a steps of reciprocating the helical member through an apparatus comprising a first scrubbing member having a working surface adapted to remove deposits from a first helical face of a helical member passed thereover, the first scrubbing member is being rotatably mounted on the apparatus such that, as the first helical face of the helical member is reciprocated over the first scrubbing member, the first helical face causes the first scrubbing member to rotate such that a working surface of the first scrubbing member remains substantially in contact with the first helical face to thereby remove deposits from the first helical face of the helical member.
Apparatus for cleaning a helical member, the apparatus comprising:—
- a first helical member retaining arrangement adapted to hold an end portion of a helical member, and
- a handle member,
- the retaining arrangement being rotatably mounted relative to the handle member such that, when a user reciprocates the helical member past a scrubbing arrangement to remove debris from the helical member, the helical member is able to rotate relative to the handle member.
A method of cleaning a helical member comprising the steps of securing an end of a helical member to an apparatus comprising a first helical member retaining arrangement adapted to hold an end portion of a helical member and a handle member, the retaining arrangement being rotatably mounted relative to the handle member such that, when a user reciprocates the helical member past a scrubbing arrangement to remove debris from the helical member, the helical member is able to rotate relative to the handle member, and reciprocating the helical member through or over a scrubbing arrangement in order to remove deposits from the helical member.
A kit of parts for cleaning a helical member, the kit of parts comprising:
- a handle member;
- a first helical member retaining arrangement adapted to hold an end portion of the helical member, the retaining arrangement being rotatable relative to the handle member;
- and
- a scrubbing arrangement comprising:
- a fixed first scrubbing member having a working surface adapted to remove deposits from a first helical face of the helical member passed thereover such that, as the first helical face of the helical member is reciprocated over the first scrubbing member, the first helical face causes the helical member to rotate relative to the handle member such that a working surface of the first scrubbing member remains substantially in contact with the first helical face to thereby remove deposits from the first helical face of the helical member:
- and
- a second scrubbing member adapted to remove deposits from a second helical face of the helical member passed between the first and second scrubbing members such that, as the second helical face of the helical member is reciprocated over the second scrubbing member, the second helical face also causes the helical member to rotate such that a working surface of the second scrubbing member remains substantially in contact with the second helical face to thereby simultaneously remove deposits from the second helical face in addition to the first helical face of the helical member.
