Abstract
A pneumatically driven tool (e.g., an impact tool) includes a pneumatically driven motor; an electric generator generating electrical power from movement of the pneumatically driven motor, or an impact mechanism connected thereto; and an on-board light that is powered by the generated electrical power. The pneumatically driven motor is rotated by compressed air or gas and drives an impact mechanism with one or more hammers and an anvil. Impact of the hammer(s) with the anvil, in turn, move an output shaft of the pneumatically driven tool. The electric generator harnesses the rotational movement of the pneumatically driven motor and/or the impact mechanism to electrically power the on-board light.
Claims16
An impact tool that is pneumatically driven by compressed air or gas, the impact tool comprising:
- a housing;
- an output shaft passing through the housing and configured to receive a socket;
- a pneumatically driven motor disposed within the housing, the pneumatically driven motor configured to rotate from the compressed air or gas and drive movement of the output shaft;
- an electric generator configured to generate electrical power from rotation of the pneumatically driven motor being driven by the compressed air or gas;
- a clutch to engage and disengage the electric generator to the pneumatically driven motor;
- and
- a light source configured to be electrically powered using the electrical power generated by the electric generator, the light source disposed on the housing and at least substantially encircling the output shaft.
