Patent ID: 7456350

Claim:
A drum for an elongated tool member having a first end portion, the drum comprising: a shell having a first end and a second end; a first head and a second head; a first rim coupled to the first head and to the first end of the shell; a second rim coupled to the second head and to the second end of the shell; a plurality of coupling members, each having a passageway with a first end portion and a second end portion, each of the coupling members coupled to the shell; a plurality of first elongated members, each having an longitudinal dimension, having a first end portion rotatably coupled to the first rim, having a second end portion rotatably coupled to the first end portion of the passageway of a different one of the coupling members, and extending therebetween the first rim and the coupling member a first distance, each of the first elongated members rotatably coupled to rotate about the longitudinal dimension to change the first distance and thereby change a first force imparted upon the first rim by the first elongated member, each of the first elongated members having a second passageway extending therethrough the first elongated member along the longitudinal dimension from the first end portion to the second end portion, the second passageway sized to receive a portion of the elongated tool member to allow the portion of the elongated tool member to be removably inserted into the second passageway to extend from the first end portion through the second passageway to position the first end portion of the elongated tool member at a first location outside of the second passageway past the second end portion; and a plurality of second elongated members, each having an longitudinal dimension, having a first end portion rotatably coupled to the second rim, having a second end portion rotatably coupled to the second end portion of the passageway of a different one of the coupling members, and extending therebetween the second rim and the coupling member a second distance, each of the second elongated members rotatably coupled to rotate about the longitudinal dimension to change the second distance and thereby change a second force imparted upon the second rim by the second elongated member, each of the second end portions positioned within the respective coupling member relative to a different one of the first elongated members and configured to engage with the portion of the elongated tool member when the portion of the elongated tool member is positioned at the first location.
