TECHNICAL FIELD
[0001] Fire
fighters, particularly fire fighters that fight forest fires, can
find themselves surrounded by water, but without a way to convey the
water to the source of the fire. Often these brave souls have hiked miles
into the wilderness supplied only with what they can carry. What they
can carry typically includes a chainsaw, but does not include a water
pump. The present disclosure provides portable pump systems,
chainsaw accessories, and chainsaw pump accessory kits that can be
used by those that fight forest fires, for example.
BACKGROUND
[0002] Water pumps and chainsaws are two very important tools for
combatting wildfires. They are also extremely heavy for firefighters to
carry, especially when walking for miles into and around massive fires.
The energy of these brave public servants is probably the most valuable
tool in combatting large, destructive fires. Thus,
with all of the
equipment that a firefighter already has to have to do his or her job,
efficiency and reduction of bulky equipment are paramount. The current
disclosure helps the firefighter by providing a centrifugal water pump
that can be attached to the bar of a chainsaw, eliminating the necessity
of carrying excessive gear, such as different fuel for different motors,
