ABSTRACT:
Firemen and other rescue workers customarily use various portable rescue equipment, such as, saws, or prying tools, and air evacuation or exhaust fans powered by internal combustion motors. As a lack of atmospheric air or a reduction to levels not supporting internal combustion affects the proper functioning of such motors, atmospheric air is excluded from the carburetors thereof by an air exclusion hood means attached thereto or associated therewith, and air from an air pack worn by the worker or other suitable remotely located source of compressed air is introduced thereinto through a line from such source to a demand type regulator valve as such fresh air is demanded or required by the motor. Thus, a supply of uncontaminated air from the air pack or remote source may be fed into the demand regulator valve and, thence, into the carburetor to fulfill the requirements of the motor and to insure the proper functioning thereof.
