Abstract

A tool for aiming a nozzle assembly having a fluid outlet and a cap is provided. The tool includes a housing defining a bore. The bore has a side wall radially disposed about an axis. The tool also includes a laser assembly including a laser emission source configured to produce a light beam collinear with the axis of the housing. The laser assembly also includes a power supply. The tool further includes at least one of a switch and an electrical contact provided within the housing and adapted to be in electrical communication with the power supply and the laser emission source based on a contact with the nozzle assembly. The tool is installed on the nozzle assembly such that the bore is adapted for placement about an outer surface of the nozzle assembly so that the fluid outlet is substantially concentric about the axis.

Claims4

Dependent claims

An alignment assembly, comprising:

a tool comprising
a housing having an internal surface that defines a bore therethrough, the bore extending from a first aperture at a first end of the housing to a second aperture at a second end of the housing;
a laser assembly disposed within the bore of the housing, the laser assembly including:
a laser emission source configured and arranged to produce a light beam that projects through the first aperture of the housing, and
a power supply;
and
a switch disposed entirely within the bore of the housing between the laser emission source and the second aperture, the switch being configured to effect selective electrical communication between the power supply and the laser emission source;
and a nozzle assembly disposed within the bore of the housing between the switch and the second aperture,
the nozzle assembly bearing on the switch, thereby energizing the laser emission source by effecting electrical communication between the power supply and the laser emission source via the switch.
