Patent number: 10632559Abstract: A drive roll carrier includes a hub coupled to and extending axially from a gear along a rotational axis, an engagement feature coupled to and extending axially from the gear, and a retainer disposed about the hub. The gear is rotatable via a wire feed motor. The engagement feature is configured to engage the drive roll and urge rotation of the drive roll as the gear is rotated. The retainer includes an alignment feature configured to receive the drive roll. The retainer may be selectively locked into one of a first position relative to the hub and a second position relative to the hub. The alignment feature and the engagement feature are aligned in the first position and not aligned in the second position, and the retainer may be transitioned between the first and second positions without being translated along the hub in a direction of the rotational axis.Type: GrantFiled: April 10, 2017Date of Patent: April 28, 2020Assignee: ILLINOIS TOOL WORKS INC.Inventors: Jon Michael Patterson, Thomas Don Lahti
