Patent number: 10723009Abstract: A powered tool is depicted which includes a transmission that permits an input shaft to rotate in a single rotational direction during operation of the powered tool, but otherwise allowing the rotation of an output shaft to change direction depending on the arrangement of the transmission. In one form a first shaft is coupled with a planetary gearing arrangement which includes planetary gears and a ring gear. A second shaft is coupled with a moveable clutch. When the clutch is moved to a first position it is coupled to bypass the ring gear which provides rotation of the second shaft in the same direction as the first shaft. When the clutch is moved to a second position to engage the ring gear the direction of rotation of the second shaft is opposite the first shaft.Type: GrantFiled: November 13, 2017Date of Patent: July 28, 2020Assignee: Ingersoll-Rand Industrial U.S., Inc.Inventors: Warren A.

Patent number: 10569343Abstract: An attachment retainer having a collar that, when at a collar locked position, has a first surface that is positioned above an open end of a passageway of a spindle to assist in retaining locking members in locking engagement with a driven tool. When in a collar release position, a second surface of the collar is positioned above the open end of the passageway to provide a space to receive a portion of the locking members so that the locking members can be disengaged from the driven tool. A plunger is displaceable to a position beneath another opening of the passageway to assist in retaining locking members in the passageway. A cam surface of a release ring can engage, and facilitate linear displacement of, release members as the release ring is rotated, which can facilitate axial displacement of the collar from the collar locked position to the collar release position.Type: GrantFiled: November 6, 2017Date of Patent: February 25, 2020Assignee: Ingersoll-Rand CompanyInventor: Mark T.
