Abstract: An anvil assembly for a rotary tool is provided. The anvil assembly includes an anvil body having a cylindrical portion operably coupled to the rotary tool's drive mechanism and having a drive output portion configured to releasably engage a corresponding socket thereon. The anvil body may also have a transition region between a shape of the drive output portion and a shape of the cylindrical portion, wherein the transition region gradually transitions the shape of the drive output portion to the shape of the cylindrical portion. A collar may be releasably coupled to the anvil body, the collar having a first end and a second end, the first end configured to engage the shape of the drive output portion and the second end configured to engage the cylindrical portion, wherein the first end has a flat face defining a shoulder for contacting the socket releasably engaged on the anvil body.

Abstract: A device containing fragments of a failed high torque device such as hydraulic torque device, geared air driven torque machine or impact wrench. The device is a sleeve formed of a woven or web-like material that is positioned around at least a driving or socket end of the high torque device. The sleeve absorbs the impact of fragments upon failure of the high torque device, preventing the fragments from becoming airborne. The sleeve may be assembled with the high torque device during construction of the high torque device, or may be added to the high torque device at a later time. The sleeve may be retro-fit onto the high torque device. The sleeve may be pre-molded, shrink-fit, hot-dipped, slid, rolled or woven onto the high torque device.

Abstract: A pneumatic motor having a motor chamber having an inner surface with an eccentric longitudinal axis, a motive gas fluid inlet, and at least one end wall located transversely to the longitudinal axis with an exhaust aperture located therethrough. A rotor is rotatably disposed in the motor chamber on the eccentric longitudinal axis and having a plurality of radial slots, the rotor defining a first rotational position with respect to the longitudinal axis at which the distance between the rotor and the motor chamber is a minimum. A plurality of vanes is slidably carried within the plurality of radial slots and rotationally moving between the fluid inlet and the exhaust aperture during rotation of the rotor.

Abstract: A forward/reverse mechanism and a pneumatic pressure operated power tool incorporating the mechanism are provided. The mechanism includes a rocker button having two lever portions and an actuator disposed next to one lever portion or a pair of actuators disposed next to both lever portions for engaging and rotating opposite sides of a periphery of a rotary valve spool for effecting rotation of the rotary spool in response to movement of the rocker button.

Abstract: A rotary impact tool having a twin hammer mechanism that generally includes a housing having a hollow cage or carrier member positioned therein. A pair of hollow hammer members are pivotally positioned relative to the hollow cage or carrier member so the hollow hammer members rotate with the hollow cage or carrier member under drive from an air motor output shaft. An anvil is positioned inside the hollow hammer members and the anvil rotates relative to the hollow hammer members. The anvil preferably includes a forward anvil lug, a rearward anvil lug and an annular ring positioned intermediate the forward anvil lug, and the rearward anvil lug. To facilitate assembly of the anvil through the hollow hammer members, the annular ring could be a reduced diameter annular ring or the sides of a full diameter annular ring could be reduced or narrowed. Positive spacing of the hollow hammer members can be achieved by placing a spacer between the hollow hammer members.

Abstract: A spring clip retainer for securing a spool in a bore in, for example, a power tool wherein the spool forms a swivel connection for a source of pressure fluid to operate and or control the device.
