Abstract
A pneumatic lighting apparatus for use with a pneumatically driven tool includes a pneumatic motor driven by compressed air, and an electrical generator that is driven by the mechanical output of the motor for generating an electrical current. A lamp is provided in a circuit with the generator for emitting light adapted to be directed onto an area in which the tool is being used. A conduit is provided which is connected between the outlet of the motor and an inlet of the tool in order to deliver compressed air from the apparatus to the tool. In order to permit control of the lighting apparatus independent of operation of the tool, a control valve is provided for controlling the flow of compressed air through the motor, and an exhaust valve controls the flow of compressed air between the conduit and an exhaust.
Claims26
A pneumatic lighting apparatus comprising:
- a lamp;
- an electrical generator for generating electrical current in response to a mechanical input;
- an electrical circuit connecting the generator with the lamp for energizing the lamp when current is available from the generator;
- a pneumatic motor for providing the mechanical input to the generator;
- a valve means for selectively directing compressed air through the motor to drive the motor;
- and
- a ventilation manifold for exhausting compressed air from the apparatus after the compressed air has passed through the pneumatic motor, the ventilation manifold including a plurality of holes for directing the air exhausted from the apparatus, and being movable relative to the lamp so that the direction in which the air is exhausted may be changed.
A pneumatic lighting apparatus for use with a pneumatically driven tool provided with an air inlet, the apparatus comprising:
- a lamp for emitting light adapted to be directed onto an area in which the tool is being used;
- generator housing including an inlet adapted for connection to a source of compressed air, an outlet, and an exhaust;
- a conduit for connecting the outlet of the housing with the air inlet of the tool to deliver compressed air from the apparatus to the tool;
- a pneumatic motor in the housing connected between
- the inlet and the outlet, the motor being driven by compressed air passing through the apparatus and providing a mechanical output;
- an electrical generator that is driven by the mechanical output of the motor for generating electrical current;
- an electrical circuit including the generator and the lamp for supplying electricity to the lamp;
- a control valve means for controlling the flow of compressed air through the motor;
- and
- an exhaust valve means for controlling the flow of compressed air from the exhaust, the exhaust valve means permitting compressed air to flow from the exhaust when the tool is not in use so that the lighting apparatus may be used independent of the tool.
A pneumatic tool comprising:
- a housing including an inlet adapted for connection to a source of compressed air, and an exhaust means for exhausting compressed air from the housing;
- a first pneumatic motor in the housing connected between the inlet and the exhaust means, and being driven by compressed air;
- an output shaft supported on the housing and driven by the first pneumatic motor;
- a second pneumatic motor in the housing connected between the inlet and the exhaust means, and being driven by compressed air to provide a mechanical output;
- an electrical generator that is driven by the mechanical output of the motor for generating electrical current;
- a lamp supported on the housing;
- an electrical circuit connecting the generator and the lamp for supplying electricity to the lamp;
- and
- a control valve means for controlling the flow of compressed air through the first and second motors.
