Patent CA-2099291-A1 (CA)
Inventor: TROUTEAUD LEE E
IPC: B65C1/02
Filed: 1993-06-28
Abstract: Label applier of an automatically operated label applying system is selectively controlled by a machine operator to rotate self-adhesive labels to any of a variety of different angular orientations in response to interception of a driving bevel gear at a predetermined position.  A driven pinion gear which carries a vacuum wand with a vacuum gripper on an end thereof rotates the wand and label to any one of 90, 180 or 270 degrees, depending on which of three intercepting pins is activated under selective control of an operator.  In the event no intercepting pin is activated, the drive gear rotates through the same angle as its supporting shaft and effectively avoids rotation of the driven gear and turning of the label.  The label applier is remotely controlled by automatic means, thereby avoiding the necessity to make manual changes to the applier each time a new angular orientation becomes necessary.

Abstract: A manually powered fastening tool which stores and instantly releases the energy of a spring (41) such that it may force a staple type fastener (61) into an object by an impact blow. The squeeze handle (22) is hinged (52) near the end of the tool body opposite the end from which the staples (61) exit. The user grips the tool near the staple exit end and pushes the squeeze handle (22) toward the intended staple impact point. This novel arrangement causes the user to force the staple into the receiving object with the same hand that pushes the squeeze handle (22) toward the tool body (10). Improving from the prior art, the present design ensures that the staple exit end of the tool body will not lift away from the receiving object.

Inventor: ROBERTS PETER M
IPC: B25B21/00
Filed: 1994-04-08
Abstract: A tool of the type having a drive stud for receiving and releasing a tool attachment includes an opening in the drive stud and a locking pin movably mounted in the opening.  The opening defines upper and lower ends, and the lower end of the opening is located at a portion of the drive stud constructed for insertion into the tool attachment.  The lower end of the locking pin is constructed to engage the tool attachment when the locking pin is positioned in an engaging position and to release the tool attachment when the locking pin is moved to a release position.  An actuating element is movably positioned on the drive stud, and the actuating element is coupled to the locking pin to move the locking pin from the engaging to the release position as the actuating element moves along the longitudinal axis.  An anti-rotation key is positioned between the actuating element and the drive stud to slide in a groove formed in either the actuating element or the drive stud and thereby to limit rotation of the actuating element and associated side loading of the locking pin.  If desired, a resilient retaining element can be positioned in a recess in either the actuating element or the drive stud to limit movement of the actuating element relative to the drive stud along the longitudinal axis.
