Abstract: A pneumatic motor includes a stator having a stator inner wall including a dwell region and a rotor eccentrically disposed within the stator. The rotor is configured to rotate about the axis of rotation and includes a plurality of vanes disposed around the rotor. Each vane of the plurality of vanes is configured to slide within a respective slot formed in the outer surface of the rotor between a fully retracted position and a fully extended position as the rotor rotates about the axis of rotation to maintain contact with the stator inner wall. The stator inner wall has a radius relative to the axis of rotation that is substantially constant within the dwell region so that vanes of the plurality of vanes are in the fully extended position within the dwell region.

Abstract: A pneumatic wrench including a pneumatic motor that includes a rotor, a rotor housing, an endplate, and a wear plate. The rotor has an output shaft configured to rotate about an axis and a plurality of vanes that extend radially from the axis that compressed air exerts work against to drive the rotor. The rotor housing has a cavity configured to house the rotor, receive the compressed air, and direct the compressed air about the rotor and out of the rotor housing. The endplate is coupled to the rotor housing and configured to receive the output shaft. The endplate includes a channel that is in fluid communication with the cavity. The wear plate is disposed between the endplate and the rotor housing and defines an exhaust port between the cavity and the channel for directing airflow from the cavity to the channel in an axial direction.

Abstract: An impact tool having a front lubrication assembly. The front lubrication assembly includes a lubrication port, a lubrication passage and at least one lubrication channel that directs a lubricant injected from a front end of the impact tool directly into an impact assembly of the impact tool. The lubrication passage extends through an anvil assembly of the impact tool, along an axis of rotation of the impact drive mechanism. The at least one lubrication channel extends away from the lubrication passage and delivers the lubricant to at the impact mechanism. The front lubrication assembly is accessed on a front end of the impact tool. The anvil assembly may be a split anvil assembly having an external anvil portion and an external anvil portion.

Abstract: An impact tool having a split anvil assembly includes an internal anvil portion fixed inside a housing of the impact tool and an external anvil portion that is removably attached to the internal anvil portion and extends outside of the housing. The external anvil portion includes a retractable pin biased to an extended position to engage the internal anvil portion to secure the external anvil portion to the internal anvil portion and depressed to a retracted position to permit the external anvil portion to be disengaged from the internal anvil portion. The internal anvil portion and the external anvil portion may include respective internal and external grooves that interconnect with each other to link the movement of the internal anvil portion to the external anvil portion.

Abstract: A power tool comprises an adjustable auxiliary handle assembly that facilities safe use of the tool by the operator when handling heavy duty handheld machinery. The adjustable auxiliary handle assembly comprises a strap, a handle base, an over-center linkage assembly, a locking lever, a locking lever and an adjustable knob. The strap is easily released and able to rotate and be locked in a different position convenient and comfortable to the operator. The auxiliary handle assembly is adjustable and can be operated with one hand (e.g., one-handed operation). The over-center linkage assembly holds the auxiliary handle position in place while allowing the power tool to be used in high-torque/high load applications.

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 door for an outdoor cabinet such as those used in telephony or CATV systems. The door has a first gasketed section to provide a first area of the cabinet with an airtight seal for protecting components housed therein from the outside environment. This first section of the door also includes a multi-point compression latch. The door has a second ungasketed section which ventilates gases around its unsealed perimeter from a second area of the cabinet housing batteries. This second section of the door includes a slam latch that is automatically engaged when the compression latch on the first door section is engaged.

Abstract: A mounting tree for power transfer devices such as those used in hybrid fiber/coaxial systems. The mounting tree is installed inside an outdoor cabinet housing the power transfer devices. The mounting tree is located in a corner of the cabinet that is partially exposed to the outside environment. An intermediate mounting bracket is used to attach the mounting tree to the cabinet. The intermediate mounting bracket is permanently installed near the aforementioned corner such that the power transfer devices may be installed on the mounting tree before the tree is attached to the intermediate mounting bracket inside the cabinet.
