Abstract:
A housing (12) for a power tool (12) includes a primary handle (34) configured for accommodating a primary hand used to control the operation of the tool, the handle having a first end closer to a power source (14) of the tool, and a second end distal of the power source, a secondary handle (50) configured for accommodating a secondary hand, being associated with the distal end and defining a distal extremity of the tool offsetting the power source.
Abstract:
An interface adaptor connector (200) for effectively connecting one end of a seismic sway brace or restraint pipe (218), which is fixedly connected to, for example, a water pipe of a building sprinkler system, to a suitable support anchor (230) which is adapted to be fixedly connected to an overhead ceiling or structural beam member of a building within which a sprinkler system has been installed.
Abstract:
A combustion tool having a gas actuated magazine advance includes a combustion chamber defined in part by a cylinder (40), a valve sleeve (38) axially reciprocating relative to the cylinder and an upper surface (48) of a piston (34), a pneumatically actuated magazine fastener mechanism (56), and an exhaust driven actuation feed tube (60) having a first end (62) configured for insertion into an opening in the cylinder in fluid communication with the combustion chamber and a second end (66) connected to the magazine fastener advance mechanism.
Abstract:
A driver blade (40) for use in a combustion-powered fastener-driving tool (11) includes an elongate tubular body (42) having a combustion end (44) and a driving end (46), the combustion end being configured for attachment to a piston (28), and the driving end having a substantially solid cross-section. The tubular body is in fluid communication with a tool combustion chamber (10).
Abstract:
An air filter assembly comprising a filter element (70) for a combustion tool includes a filter medium having pores with a pore size greater than a target particle size.
Abstract:
A pneumatic fastener driving tool is configured to drive a threaded fastener using both linear and rotational motion. The tool allows a fastener to first be driven linearly, without rotation, through a surface material and into a substrate material, preferably to a depth that causes the fastener to at least pierce the substrate material. The tool then rotates the threaded fastener and causes it to fully engage the substrate material, thereby fastening the surface material to the substrate material. The tool has sufficient linear force to drive a fastener into relatively hard substrate materials, such as steel studs, and has a stationary air motor assembly to reduce recoil generated during the driving process. The tool further comprises a gear reducer assembly that uses a compound planetary gear in order to reduce the overall length of the tool.
Abstract:
A housing (12) for a power tool (10) having a power source (14), includes a fuel cell chamber (40) configured for attachment to the power source (14) and dimensioned for operationally receiving a fuel cell (60) in either one of a first orientation and a second orientation.

A housing for a power tool having a power source, includes a fuel cell chamber configured for attachment to the power source and dimensioned for operationally receiving a fuel cell in either one of a first orientation and a second orientation.
Abstract:
A cage and upper probe assembly for use in a fastener-driving tool includes a cage (46) including a base (48) and a plurality of generally normally extending arms (50) configured for attachment to a valve sleeve (22) , a probe (42) configured for direct attachment to the cage and having at least one lobe formation (58) for receiving a pusher rod (38), and the probe being attached to the cage so that impact of the pusher rod upon the probe is directly transmitted to the cage.
