Patent number: 8931676Abstract: A fastening tool can include a housing comprising a nosepiece and a handle. The handle can define a first longitudinal axis. A magazine can be connected to the housing for storing a fastener. The magazine can define a second longitudinal axis that is substantially parallel to the first longitudinal axis and a fastener channel for receiving a fastener. The magazine can be movable relative to the housing between an alignment position wherein the distal tip of the fastener engages a workpiece and an activation position wherein the magazine moves toward the housing upon movement of the handle toward the workpiece. A driving mechanism can be disposed within the housing for driving the fastener into a workpiece. A trigger assembly can be coupled to the housing for activating the driving mechanism upon actuation of a primary trigger and movement of the magazine into the activation position.Type: GrantFiled: August 11, 2008Date of Patent: January 13, 2015Assignee: Black & Decker Inc.Inventor: C.

Patent number: 8439124Abstract: A pneumatic power tool with a housing assembly, a pneumatic motor assembly, an output member, and a trigger assembly. The housing assembly has a body, a cap member and a gasket assembly. The body defines a motor cavity and an inlet manifold. The cap member defines an air inlet port. The gasket has a first portion being a band formed of a compressible material and a second portion formed of a porous material. The band of the first portion is sealingly abutted against the body and cap member. The pneumatic motor assembly is received in the motor cavity defined by the body. The output member is driven by the pneumatic motor assembly. The trigger assembly is coupled to the housing assembly and is operable for selectively operating the pneumatic motor assembly. Pressurized air received into the air inlet port is filtered by the second portion of the gasket assembly and flows into the inlet manifold when the pneumatic motor assembly is operated. A related method is also provided.Type: GrantFiled: July 17, 2007Date of Patent: May 14, 2013Assignee: Black & Decker Inc.Inventor: C. Kerwin Braddock

Patent number: 7503473Abstract: A pneumatic fastener includes a housing and a handle coupled to the housing. The handle defines an inlet channel for delivering compressed gas to the housing. A trigger valve is in communication with the inlet channel and configured to actuate the pneumatic fastener. A fastener driving assembly is disposed within the housing. The fastener driving assembly includes a cylinder and a piston that reciprocates within the cylinder to drive a fastener. A valve piston is coupled to the fastener driving assembly. Actuation of the valve piston causes compressed air to drive the piston within the cylinder to drive the fastener. An outer cap is coupled to the housing and an inner cap is disposed at least partially within the outer cap. The inner cap includes an opening in communication with the trigger valve for porting the compressed air to a region above the valve piston.Type: GrantFiled: January 25, 2007Date of Patent: March 17, 2009Assignee: Black & Decker Inc.Inventors: James R.

Patent number: 5921997Abstract: A clip, clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier. The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.Type: GrantFiled: September 19, 1997Date of Patent: July 13, 1999Assignee: Ethicon Endo-Surgery, Inc.Inventors: Mark Fogelberg, J.
