A replaceable baffle for dropping high pressure air to low pressure air for atomization and for pattern shaping in a high volume low pressure (HVLP) air paint spray gun. The baffle has a first plurality of orifices for distributing and dropping the air pressure to a low pressure for atomization and has orifices arranged in two stages for dropping the air pressure to a low pressure for pattern shaping. The baffle may be replaced with a baffle having different sized orifices to permit use of different air cap and/or fluid tip designs on the spray gun when applying paints having different flow properties.

Baffle for HVLP paint spray gun

A safety device for an electrode-type steam vaporizer having an electrode assembly enclosed in a protective housing allows access to the electrodes for cleaning or adjustment only when a key, preferably the electric plug for the vaporizer, is inserted through an opening in the protective housing to release an interlock mechanism normally precluding removal of the protective housing from the electrode assembly. When the protective housing is removed, the key is automatically locked in the opening in the protective housing by a spring-biased lock pin and cannot be removed until the electrode assembly is again repositioned in the housing with the electrode assembly and housing properly assembled relative to each other. The safety device can be used in other electrical appliances, such as a toaster, that have electrical elements enclosed in a protective housing.
