Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
A battery-operated device for fanning a fire comprising a first housing, said housing including an inlet and an outlet, a fan supported by said housing for driving air through said outlet, a battery housing connected to said first housing, and a motor supported by one of said housings, said motor being positioned adjacent said first housing and being operably connected to said fan, switch means on said battery housing adapted to selectively couple said motor to batteries in the battery housing, said first housing and said battery housing are elongated members and are disposed at generally right angles with respect to each other, said first housing supporting a laterally extending projection that defines a recess intermediate said projection and said battery housing for receiving a portion of a barbecue pit, said recess is in generally facing relation to said battery housing, further including an elongated conduit, said conduit having one end connected to said outlet to form an extension of said first housing, and the other end of said conduit being substantially dish shaped.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
60 words
A device as defined in claim 2 wherein a portion of said bracket has an adjustable loop that cooperates with said batterY housing to restrain it in position, and another portion of said bracket has a laterally extending bar that cooperates with said recess to hold said first housing in position so that said outlet is received in said opening.
Claim 5
Dependent Claim
45 words
